      7.4    Administration of Funding.
             -------------------------

      7.4.1  Sources of Funds. Funds necessary to pay all costs set forth in the
             ----------------
Project Budget shall be derived from Lessor's Funds and from Lessee's funds.
Advances from Lessor's Funds and the funding of Lessee's funds shall be made as
follows:

             (a)   Subject to the satisfaction of the applicable conditions set
             forth herein, Lessor's Funds of up to a total of $8,134,044 (eight
             million one hundred thirty-four thousand forty-four dollars) for
             Total Project Costs shall be disbursed.

             (b)   Lessee's funds, which may be required at any time if Lessor
             determines, in its reasonable opinion, that (i) the total costs
             actually incurred or estimated by Lessor to be incurred for any
             line item in any Cost Category theretofore approved by Lessor
             exceed (ii) the amount budgeted for such line item, and there are
             then no funds remaining in the Construction Cost Contingency (as
             hereafter defined to cover such excess). Upon Lessor's demand,
             Lessee shall deposit cash in an account approved by Lessor, and the
             funds so deposited shall be disbursed in accordance with the terms
             of this Lease prior to any subsequent advance of Lessor's Funds. In
             any event, Lessee shall be responsible for funding (I) Total
             Project Costs that exceed $8,134,044 (eight million one hundred
             thirty-four thousand forty-four dollars), and (II) all Total
             Project Costs incurred and not funded on or before September 15,
             1997.

      7.4.2  Retainage and Other Reserves. At the time of each advance, the
             ----------------------------
total unadvanced Lessor's Funds plus Lessee's funds deposited as provided above
shall be equal to the sum of the following:

             (a)   Retainage. Retainage in an amount to be determined by Lessor
                   ---------
             upon review and approval of each Construction Contract not to
             exceed 10% of labor and materials wrought into construction and/or
             eligible for payment for costs set forth in Cost Category I
             (Construction Costs) and Cost Category III (Tenant Finishes).
             Retainage with respect to a Construction Contract, less an amount
             (the "Holdback Amount") determined by Lessor but not to exceed 200%
             of the cost estimated by Lessor to complete punchlist items, shall
             be advanced upon Substantial Completion for such Construction
             Contract pursuant to Section 7.5 of this Lease.

             (b)   Remaining Development Costs. An amount sufficient, in the
                   ---------------------------
             opinion of Lessor, to pay the remaining cost of acquisition and
             development of the Expansion, including the following specific
             reserve:

                                       10
<PAGE>

             An amount to be established by Lessor not more than 5% or less than
             3% of the contract sum under each Construction Contract to which
             shall be added amounts of cost savings as hereafter defined) as
             they occur (the "Construction Cost Contingency"). A "Cost Saving"
             means the amounts by which the total amount budgeted for any line
             item in any Cost Category of the Project Budget exceeds the total
             costs actually incurred and estimated by Lessor to be incurred
             under such line item prior to Project Final Completion. The amount
             of the Construction Cost Contingency shall be reduced by (i) the
             amount of additional construction costs from any change, and (ii)
             the amount of any cost overages that occur in specific line items
             in Cost Category I (Construction Costs). The initial amount of the
             Construction Cost Contingency is $250,000 (two hundred fifty
             thousand dollars).

             If at any time Lessor determines that there are insufficient funds
             in the reserve listed above, additional cash funds may be required
             of Lessee.

Upon achievement of Project Final Completion, any Lessor's Funds that remain
undisbursed will not be disbursed, but shall be retained by Lessor and shall not
be part of the Total Project Cost.

      7.4.3  Limitations on Lessor's Obligations. Except as provided above,
             -----------------------------------
under no circumstances shall Lessor be obliged to advance any Lessor's Funds for
any line item or Cost Category in excess of the total amount specified for such
line item or Cost Category in the Project Budget, and neither Lessee nor any
third party shall be entitled to rely on amounts in any line item or Cost
Category being available for any purpose whatsoever other than payment of costs
in that line item or Cost Category. Furthermore, Lessor shall have no obligation
to make any advance if it, in its sole discretion, whether based on reports from
the Consultant or otherwise, determines that actual costs relating to any line
item or Cost Category are expected to be in excess of the total of the amounts
set forth for such line item or Cost Category in the Project Budget or that
other costs will necessarily be incurred by Lessee which are not contemplated in
the Project Budget, unless there are sufficient funds in the Construction Cost
Contingency, or unless Lessee shall fund, or (if required by Lessor) deposit in
an account approved by Lessor, the full amount of any such excess or of such
uncontemplated cost. Such amounts shall be disbursed in accordance herewith
prior to any further advance of Lessor's Funds.

      7.4.4  Timing of Advances.  Parts or the whole of any advance of Lessor's
             ------------------
Funds may be made before or after the date requested by Lessee if Lessor
believes it advisable to do so.

      7.4.5  Direct Advances to Contractors and Subcontractors.  Lessor, at its
             -------------------------------------------------
option, may make advances directly to any Contractor or Subcontractor, provided
Lessor provides notice thereof to Lessee.

      7.4.6  Deadline for funding of Lessor's Funds.  Notwithstanding anything
             --------------------------------------
herein to the contrary, Lessor shall have no obligation to advance Lessor's
Funds after October 30, 1997.

                            MAINTENANCE AND REPAIRS

     9.1  Lessor shall not be required to make any improvements to or repairs of
any kind or character to the Leased Premises except structural and roof
maintenance and repair of the Building as may be required to maintain the Leased
Premises in tenantable condition; provided, however, Lessor's failure to make
such repairs shall not relieve Lessee of the obligation to pay all sums that
become due under this Lease, except to the extent provided by Section 18.4
hereof.

     9.2  Lessee, at Lessee's sole cost and expense, shall promptly make all
repairs, perform all maintenance, and make all replacements in and to the Leased
Premises, including the Land and parking lots, that are necessary or desirable
to keep the Leased Premises in first class condition and

                                       14

repair, in a safe and tenantable condition, and otherwise in accordance with the
requirements of this Lease. Lessee shall maintain all fixtures, furnishings and
equipment (excluding Lessee's personal property) located in, or exclusively
serving, the Leased Premises in clean, safe and sanitary condition, shall take
good care thereof and make all required repairs and replacements thereto. Lessee
shall suffer no waste or injury to any part of the Leased Premises, and shall,
at the expiration or earlier termination of the Lease Term, surrender the Leased
Premises in an order and condition equal to or better than their order and
condition on the Commencement Date, ordinary wear and tear excepted. Without
limitation of the generality of the foregoing, Lessee (with respect to the
Existing Building) and at the completion of the Expansion (with respect to the
Expansion), at Lessee's sole cost and expense, shall promptly make all repairs
to (a) any pipes, lines, ducts, wires or conduits contained within the Leased
Premises, (b) Lessee's signs, (c) any heating, air conditioning, electrical,
ventilating or plumbing equipment installed in or serving the Leased Premises,
(d) all glass, window panes and doors, and (e) any other mechanical systems
serving the Leased Premises. Lessee shall be responsible, at Lessee's sole
expense, for providing all janitorial and cleaning services for the Leased
Premises. All such services shall be provided in accordance with cleaning
standards customarily maintained for similar first class properties. Lessee
shall maintain, at Lessee's sole cost and expense, a maintenance contract, or
provide comparable services by trained and qualified employees of Lessee, on the
heating, ventilation an air conditioning equipment and systems in or serving the
Leased Premises. Such contract, if entered into, shall be with a Contractor
licensed to do business in the jurisdiction in which the Leased Premises are
located and approved by Lessor, and shall cover all parts and labor. From time
to time at Lessor's request, Lessee shall provide copies of all such contracts
to Lessor. In addition, Lessor reserves the right to establish a regular
inspection and maintenance program for all Building equipment (e.g. HVAC and
elevators) maintained by Lessee and to provide all necessary or appropriate
repairs at Lessee's expense. Lessee shall pay all expenses of Lessor in
connection with Lessor's membership in the Maryland Farms Owners Association,
Inc. and Lessee shall receive all benefits arising from said membership.

     9.3  Lessee shall not paint or decorate any part of the exterior of the
Leased Premises. Additionally, Lessee shall not decorate or paint any part of
the common areas of the Leased Premises visible from the exterior thereof,
without first obtaining Lessor's prior written consent, which consent shall not
be unreasonably withheld. Lessee shall not install displays of merchandise or
other advertising in the windows of the Leased Premises.

     9.4  In the event Lessor or Lessee fails to comply with the requirements of
this Article, the non-defaulting party may perform such maintenance and repair,
and the costs thereof, plus five percent (5%) of said costs to cover overhead
with interest at the Default Rate, shall be payable to the non-defaulting party
within ten (10) days of demand therefor. In the event Lessor fails to maintain
and repair the roof of the Building as provided for in Section 9.1 above and
such failure continues for thirty (30) days after written notice from Lessee to
Lessor ( or if the maintenance or repair is of a nature as to require more than
thirty (30) days to effect a cure, then if Lessor fails to commence such
maintenance or repair within such thirty (30) day period and thereafter proceeds
diligently to effect such maintenance or repair), Lessee may itself effectuate
such maintenance or repair and may thereafter (after written notice to Lessor)
offset the reasonable cost thereof against Base Rentals payable thereafter.

     9.5  Prior to either party commencing repairs or maintenance for the other,
except in the case of an emergency (defined as a matter that immediately
threatens the life, safety or property of Lessee or its agents, employees or
invitees (e.g. roof leaks)), the non-defaulting party shall provide to the
defaulting party ten (10) days' written notice of the failure to comply with the
maintenance and repair obligations set forth herein. If the defaulting party
cures said default within said ten (10) day period or if said default cannot be
cured within a ten (10) day period and the defaulting party commences to cure
the default within said period and diligently pursues said cure to completion,
then the defaulting party shall not be deemed to be in default for purposes of
declaring this Lease in default under Article XXI and the non-defaulting party
shall have no right to commence or be reimbursed for any repairs and maintenance
which was the obligation of the defaulting party.

                                       15
<PAGE>

     9.6   If a dispute arises as to which party is responsible for repair and
maintenance, the parties shall each appoint a qualified independent engineer
having seven (7) years experience with no previous engagement with either party
to resolve the dispute. If Lessor's and Lessee's engineers are unable to resolve
the dispute, Lessor's and Lessee's engineers shall choose a third qualified
independent engineer having seven (7) years' experience with no previous
engagement with either party, and the decision of the majority of the engineers
shall be final and conclusive.


                                   ARTICLE X
                                  ALTERATIONS

     10.1  Lessor is under no obligation to make any structural or other
alterations, decorations, additions or improvements in or to the Leased Premises
except as otherwise expressly provided in this Lease.

     10.2  Lessee will not make or permit anyone to make any alterations,
additions, improvements or other changes (collectively, the "Alterations"),
structural or otherwise, in or to the Leased Premises without the prior written
consent of Lessor, except as provided in Article VI above or paragraph 10.3
below, which consent may be withheld or granted in Lessor's sole and absolute
discretion. Any Alterations made by Lessee shall be made: (a) in a good,
workmanlike, first-class and prompt manner; (b) by a contractor or by Lessee's
employees and in accordance with plans and specifications approved in writing by
Lessor; (c) in accordance with all applicable legal requirements and the
requirements of any insurance company insuring the Leased Premises or portion
thereof; and (d) after Lessee has obtained public liability and workmen's
compensation insurance policies approved in writing by Lessor, which policies
shall cover every person who will perform any work with respect to such
Alterations. If any mechanics' or materialmen's lien (or a petition to establish
such lien) is filed against the Leased Premises or any equipment within the
Leased Premises for work claimed to have been done for, or materials claimed to
have been furnished to, the Leased Premises, Lessee shall either discharge the
lien within ten (10) days thereafter, at Lessee's sole cost and expense, by the
payment thereof or file a bond acceptable to Lessor transferring the lien to the
bond.

     10.3  Notwithstanding the foregoing, Lessee shall have the right to make
Alterations without the Lessor's consent, provided such Alterations (a) are made
to the interior tenant space of the Building, (b) do not adversely affect the
structural integrity or exterior of the Building, (c) do not affect the common
areas of the Building, including but not limited to the elevators and lobby, and
(d) do not adversely affect the electrical, heating or plumbing systems
servicing the Building. Additionally Lessee shall comply with the provisions of
paragraphs 10.2(a) and 10.2(c).

     10.4  If any Alterations other than those permitted by paragraph 10.3 are
made without the prior written consent of Lessor, Lessor shall have the right at
Lessee's expense to remove and correct such Alterations and restore the Leased
Premises to its condition immediately prior thereto, or to require Lessee to do
the same. All Alterations to the Leased Premises made by either party shall
immediately become the property of Lessor and shall remain upon and be
surrendered with the Leased Premises as a part thereof at the expiration or
earlier termination of the Lease Term; provided, however, that if Lessee is not
in default under this Lease, then Lessee shall have the right to remove, prior
to the expiration or earlier termination of the Lease Term, all movable
furniture, furnishings, equipment, fixtures and Alterations (permitted by
Section 10.3) installed in the Leased Premises solely at the expense of Lessee,
provided any damage to the Leased Premises caused by such removal is promptly
repaired. If such furniture, furnishings, equipment, fixtures and Alterations
other than those permitted by Section 10.3 are not removed by Lessee prior to
the expiration or earlier termination of the Lease Term, Lessor shall have the
right at Lessee's expense to remove from the Leased Premises such furniture,
furnishings, equipment, fixtures and any Alterations other than those permitted
by Section 10.3 that Lessor designates in writing for removal

                                       16
<PAGE>

or to require Lessee to do the same and Lessee shall pay to Lessor the cost of
such removal and repair.

     10.5  Notwithstanding anything to the contrary contained herein, Lessee
shall have the right to install into the Building equipment, conduits, cables
and materials at mutually agreed upon penetration points, including the right to
install additional rooftop HVAC units, associated distribution and duct work and
microwave installation to conduct its business. Lessee shall further have the
right to install connecting equipment in the shafts, ducts and conduits of the
building, and antennas and/or microwave receivers or "up-link" on the roof, so
long as such installations are (a) in compliance with and certified by local
fire and zoning codes, (b) approved by Maryland Farms Owners Association
Architectural Control Committee, and (c) do not violate the Declaration of
Protective Covenants For Maryland Farms, dated January 1, 1987, of record in
Book 635, page 680, Register's Office for Williamson County, Tennessee and in
Book 7079, page 59, Register's office for Davidson County, Tennessee (the
"Restrictive Covenants").

                             SIGNS AND FURNISHINGS

     No sign, advertisement or notice referring to Lessee shall be inscribed,
painted, affixed or otherwise displayed on any part of the exterior of the
Building (including Lessee's windows and doors) that (a) has not been approved
by Maryland Farms Owners Association, Inc., or (b) violates the Restrictive
Covenants. If any exterior sign, advertisement or notice that does not conform
to the requirements set forth in the preceding sentence is exhibited or
installed by Lessee, Lessor shall have the right to remove the same at Lessee's
expense. All of Lessee's signs shall be: (a) installed after Lessee has
obtained, at Lessee's sole cost and expense, all permits, approvals, and
licenses required therefor, and delivered copies thereof to Lessor, and (b) at
Lessee's sole cost and expense, installed, maintained, repaired and replaced in
a first-class manner. Lessor reserves the right to affix, install and display
signs, advertisements and notices on any part of the exterior or interior of the
Leased Premises to sell or lease the Leased Premises during the six (6) month
period immediately prior to the expiration if notice to renew has not been
provided pursuant to Article XXXIV hereof or earlier termination of the Lease
Term.

                             INSPECTION BY LESSOR

     Lessor or its agents or representatives shall have the right (a) to enter
into and upon any part of the Leased Premises at all reasonable hours to inspect
the same as Lessor may deem necessary or desirable, and (b) to show the Leased
Premises to prospective tenants or brokers during the last six (6) months of the
Lease Term, as extended, and to prospective purchasers or mortgagees at all
reasonable times, provided prior notice is given to Lessee in each case, and
Lessee's use and occupancy of the Leased Premises shall not be materially
inconvenienced thereby, and Lessee shall have the right to have an employee or
representative accompany any such inspection. Lessee shall not be entitled to
any abatement or reduction of Rent by reason of the exercise of the foregoing
rights on the part of Lessor.


                                 ARTICLE XIII
                                 COMMON AREAS

     For so long as Lessee is not in default hereunder, Lessor grants Lessee a
non-exclusive license to use and occupy in common with others so entitled, the
common areas of Maryland Farms Office Park (the "Common Areas") and to exercise
all rights of Lessor as owner of the Leased Premises in connection with
membership in Maryland Farms Owners Association, Inc., as set forth in the
Restrictive Covenants.

                                    PARKING

     Lessee shall at all times during the term of this Lease have the right to
park automobiles in the outdoor parking area of the Building at no charge.
Lessor shall provide for Lessee's use paved parking spaces as shown on the site
plan prepared in connection with the Leased Premises. Lessor may change the
location of the parking lots on the Land on which the Building is situated
subject to Lessee's approval which shall not be unreasonably withheld.


                                  ARTICLE XV
                                PERMITTED USES

     Lessee shall use and occupy the Leased Premises for general office space
including an operations center with appropriate communication and informational
systems, employee cafeteria and any other lawful use; provided, however, Lessee
shall not occupy or use, or permit any portion of the Leased Premises to be
occupied or used, for any business or purpose that is unlawful or deemed to be
extra-hazardous on account of fire, or permit anything to be done that would in
any way materially increase the rate of fire or liability or any other insurance
coverage on the Building and/or its contents, cause the load upon any floor of
the Building to exceed the load for which the floor was designed or the amount
permitted by law, or use electrical energy exceeding the capacity of the then
existing feeders or wiring installations. Lessee shall further conduct its
business and control its agents, employees, invitees, and visitors in such a
manner as not to create any nuisance, or interfere with, annoy or disturb any
other tenant or owner in the Maryland Farms Office Park. Lessee's operation of
its business at its present location at 5301 Maryland Way, Brentwood, Tennessee,
is not deemed to be extra-hazardous.

                    LAWS, REGULATIONS AND RULES OF BUILDING
                         AND ENVIRONMENTAL COMPLIANCE

     16.1  Compliance with Laws and Restrictions.  Lessee shall comply with all
           -------------------------------------
applicable laws, ordinances, rules, regulations, and Restrictive Covenants
relating to the use, condition or occupancy of the Leased Premises and all
Common Areas.

     16.2  Hazardous Materials.
           -------------------

     (a)   As used herein, the term "Hazard Materials" shall mean any substance
     or material which has been determined by any federal, state or local
     governmental authority to be capable of posing a risk of injury to human
     health and safety or the environment, including all of those materials and
     substances designated as hazardous or toxic by the state in which the
     Leased Premises are located, the U.S. Environmental Protection Agency, the
     U.S. Consumer Product Safety Commission, the U.S. Food and Drug
     Administration, or any other federal, state or local governmental agency
     now or hereafter authorized by law to regulate materials and substances in
     the environment (collectively, "Hazardous Materials").

     (b)   Except for such Hazardous Materials as are used or stored in the
     Leased Premises in commercial quantities, similar to those quantities used
     or stored in similar premises by others in the same business or profession
     and which are used and/or stored in compliance with all applicable laws,
     regulations and restrictions, Lessee agrees not to introduce any Hazardous
     Materials in, on or near the Leased Premises without (I) providing Lessor
     with notice of the estimated amount and nature of such Hazardous Material,
     and (ii) complying with all applicable federal, state and local laws, rules
     and regulations relating to the use,

                                       18
<PAGE>

     storage, disposal and clean-up of Hazardous Materials including, but not
     limited to, the obtaining of proper permits with respect thereto.

     (c)  Lessee shall promptly notify Lessor of any inquiry, test,
     investigation, or enforcement proceeding by or against Lessor or Lessee
     with respect to the Leased Premises concerning any Hazardous Material.
     Lessee shall have the right, at its election to negotiate, defend, approve,
     and appeal, at Lessee's expense, any action taken or order issued by any
     governmental authority with respect to any Hazardous Materials placed in,
     on or near the Leased Premises by Lessee, its agents, employees,
     contractors or invitees.

     (d)  If Lessee's use, storage or disposal of any Hazardous Material in, on
     or near the Leased Premises results in any contamination by Hazardous
     Materials of the Leased Premises, or the soil or surface water or
     groundwater thereof (I) requiring remediation under any applicable federal,
     state or local statutes, ordinances, regulations or policies, or (ii) at
     levels which are unacceptable to Lessor, in Lessor's reasonable and good
     faith judgment, Lessee shall be obligated to clean up the contamination to
     the levels required by law or reasonably required by Lessor. Lessee further
     agrees to indemnify, defend and hold Lessor harmless from and against any
     claims, suits, causes of action costs, fees, including reasonable
     attorneys' fees, and reasonable costs arising out of or in connection with
     any such clean-up work, inquiry or enforcement proceeding in connection
     with any Hazardous Materials at any time used, stored or disposed of by
     Lessee or Lessee's agents, employees, contractors or invitees in, on or
     near the Leased Premises.

     (e)  Notwithstanding any other right of entry granted to Lessor under this
     Lease, Lessor shall have the right to enter the Leased Premises or to have
     Lessor's environmental consultants (retained by Lessor at its expense)
     enter the Leased Premises during the term of this Lease for the purpose of
     inspections to determine (i) whether the Leased Premises are in conformity
     with federal, state and local statutes and regulations pertaining to the
     environmental condition of the Leased Premises; (ii) whether Lessee has
     complied with its obligations under this Article XVI, and (iii) the
     corrective measure, if any, required to Lessee to comply with laws
     governing the use, storage and disposal of Hazardous Materials or governing
     the removal of Hazardous Materials. Lessee agrees to provide access to the
     Leased Premises and reasonable assistance to Lessor or its environmental
     consultants for such inspections. Such inspections may include, but are not
     limited to, entering the Leased Premises or adjacent property leased by
     Lessee upon such consultant's recommendation with drill rigs or other
     machinery for the purpose of obtaining laboratory samples. Lessor shall not
     be limited in the number of such inspections during the term of this Lease.
     If such consultants determine that the Leased Premises are contaminated by
     Hazardous Materials, Lessee shall, in a timely manner, at its expense,
     remove such Hazardous Materials to the extent required pursuant to this
     Article XVI. The rights granted to Lessee herein to inspect the Leased
     Premises shall not create a duty on Lessor's part to inspect the Leased
     Premises or liability of Lessor for Lessee's use, storage or disposal of
     Hazardous Materials, it being understood that Lessee shall be solely
     responsible for all liability in connection therewith.

     (f)  Lessee's obligations under this Article XVI shall survive termination
     or expiration of this Lease.


                                 ARTICLE XVII
                              PEACEFUL ENJOYMENT

     Lessee shall have the right to peacefully occupy, use and enjoy the Leased
Premises during the Lease Term, subject to the other terms hereof and the
exceptions to Lessor's title set forth on Exhibit N, provided Lessee pays the
                                          ---------
Rent and other sums herein required to be paid by Lessee and performs all of
Lessee's covenants and agreements herein contained.

                                 ARTICLE XVIII
                       LIMITATION OF LESSOR'S LIABILITY

     18.1  Lessor and its employees and agents shall not be liable to Lessee,
Lessee's employees, agents, assignees, subtenants, licensees, concessionaires,
or to any other person or entity for any damage (including indirect and
consequential damage), injury, loss, compensation or claim, including but not
limited to claims for the interruption of or loss to Lessee's business, based
on, arising out of or resulting from any cause whatsoever (except as otherwise
provided in this Article), including but not limited to the following: repairs
to any portion of the Leased Premises which are the obligation of Lessee;
interruption in the use of the Leased Premises or any equipment therein; any
accident or damage resulting from the use or operation (by Lessor, Lessee or any
other person or entity) of the heating, cooling, electrical, sewerage, or
plumbing equipment or apparatus; the termination of this Lease by reason of the
destruction of the Leased Premises; any fire, robbery, theft, vandalism,
mysterious disappearance and/or any other casualty; the actions of any other
tenants of the Leased Premises or of any other person or entity; and any leakage
in any part or portion of the Leased Premises, or from water, rain, ice or snow
that may leak into, or flow from, any part of the Leased Premises, or from
drains, pipes or plumbing fixtures in the Leased Premises, provided that Lessor
shall be liable for any damage caused by leakage or any other cause resulting
from Lessor's failure to properly maintain the structural systems and the roof
of the Building pursuant to Article IX hereof. It further is understood and
agreed that any failure or inability to furnish any services required by this
Lease to be furnished by Lessor shall not be considered an eviction, actual or
constructive, of Lessee from the Leased Premises and shall not entitle Lessee to
terminate this Lease or to an abatement of any Rent payable hereunder, except as
set forth in Section 9.4 above. Any goods, property or personal effects stored
or placed by Lessee, its employees or agents in or about the Leased Premises
shall be at the sole risk of Lessee, and Lessor shall not in any manner be held
responsible therefor. Notwithstanding the foregoing provisions of this Article,
Lessor shall not be released from liability to Lessee for any physical injury to
any natural person or damage to personal property caused by the gross negligence
or willful misconduct of Lessor or its employees to the extent such injury or
damage is not covered by insurance (a) carried by Lessee or such person, or (b)
required by this Lease to be carried by Lessee.

     18.2  Lessee shall indemnify and hold Lessor harmless from and against all
costs, damages, claims, liabilities and expenses (including attorneys' fees)
suffered by or claimed against Lessor, directly or indirectly, based on, arising
out of or resulting from (i) use and occupancy of the Leased Premises, (ii)
repair or maintenance of the Leased Premises which are the obligations of
Lessee, (iii) any act or omission by Lessee or Lessee's employees, agents,
assignees, subtenants, contractors, licensees or invitees, or (iv) any breach or
default in the performance or observance of Lessee's covenants or obligations
under this Lease.

     18.3  In the event that at any time any landlord hereunder shall sell or
transfer the Leased Premises or such landlord's interest therein, said landlord
shall not be liable to Lessee for any obligations or liabilities based on or
arising out of events or conditions occurring after the date of such sale or
transfer. Within five (5) days after the written request of any purchaser or
transferee of the Leased Premises of any landlord's interest therein, Lessee
shall attorn to such purchaser or transferee.

     18.4  In the event that at any time during the Lease Term Lessee shall have
a claim against Lessor, Lessee shall not have the right to set off or deduct the
amount owed or allegedly owed to Lessee from any Rent or other sums payable to
Lessor except with respect to claims made by Lessee concerning Lessor's failure
to make timely repairs to the Leased Premises' roof and/or structural systems,
it being understood that Lessee's sole remedy for recovering upon a claim not
concerning the roof or structural systems shall be to institute an independent
action against Lessor.

     18.5  Lessee agrees that in the event Lessee or any of Lessee's employees,
agents, subtenants, licensees, or concessionaires is awarded a money judgment
against Lessor, the sole

                                       20
<PAGE>

recourse for satisfaction of such judgment shall be limited to execution against
the estate and interest of Lessor in the Leased Premises; in no event shall any
other assets of Lessor, or of any officer, director or employee of Lessor or of
any other person or entity associated with Lessor be available to satisfy or
subject to such judgment, nor shall any officer, director or employee of Lessor
or any other person or entity be held to have any personal liability for
satisfaction of any claims or judgments against Lessor and/or any officer,
director or employee of Lessor in such person's capacity as an officer, director
or employee of Lessor


                                  ARTICLE XIX
                             DAMAGE OR DESTRUCTION

     19.1  If the Leased Premises are totally or partially damaged or destroyed
from any cause, thereby rendering the Leased Premises totally or partially
inaccessible or unusable, Lessor shall diligently restore and repair the Leased
Premises to substantially the same condition it was in prior to such damage;
provided however, that (a) if such repairs and restoration cannot be completed
within one year after the occurrence of such damage or destruction (taking into
account the time needed for effecting a satisfactory settlement with any
insurance company involved, removal of debris, preparation of plans and issuance
of all required governmental permits), then either Lessor or Lessee shall have
the right to terminate this Lease by giving written notice of termination to the
other within forty-five (45) days after the occurrence of such damage or
destruction, or (b) if such damage or destruction occurs within forty-eight (48)
months prior to the expiration of the Lease Term, then Lessor shall have the
right, at its sole option, to terminate this Lease by giving written notice of
termination to Lessee within forty-five (45) days after the occurrence of such
damage or destruction, except that should such damage or destruction occur
during the last forty-eight months of the initial fifteen (15) year term or the
first five (5) year extension period described in Article XXXIV and Lessee
exercises its option to extend the Lease Term for five (5) years pursuant to
Article XXXIV within forty-five (45) days of the date of such damage or
destruction, then Lessor shall not have the right to terminate this Lease and
will proceed to repair and restore the Leased Premises. If this Lease is
terminated by Lessor in accordance with the above procedure, then Base Rental
and Additional Rental payable hereunder shall be apportioned and paid to the
date of said damage or destruction. If this Lease is not terminated as a result
of such damage or destruction, then until such repair and restoration of the
Leased Premises are substantially complete, the Base Rental and Additional
Rental shall be abated as to that portion of the Leased Premises which is
unsuitable for occupancy by Lessee until such repair or restoration is
completed. If this Lease is not terminated as a result of such damage or
destruction, then except as otherwise specified in Section 19.2, Lessor shall
bear the cost and expenses of such repair and restoration of the Leased Premises
to the extent of the insurance proceeds paid in connection with such damage or
destruction, and Lessee shall pay to Lessor the amount by which such costs and
expenses exceed the insurance proceeds, if any, actually received by Lessor on
account of such damage or destruction. Notwithstanding anything above to the
contrary, Lessor shall have the right to terminate this Lease in the event (a)
the insurance is insufficient to pay the full cost of such repair and
restoration, (b) the lenders fail or refuse to make such insurance proceeds
available for such repair and restoration, or (c) zoning or other applicable
laws or regulations do not permit such repair and restoration.

     19.2  Notwithstanding anything above to the contrary, if Lessor repairs and
restores the Leased Premises as provided in Section 19.1, Lessor shall not be
required to repair, restore or replace any decorations, alterations or
improvements to the Leased Premises previously made by Lessee unless adequate
insurance proceeds are available to pay the full costs thereof. It shall be
Lessee's sole responsibility to repair, restore or replace any trade fixtures,
furnishings, equipment or personal property belonging to Lessee to substantially
their same condition prior to such damage or destruction; provided, however,
Lessee shall not be obligated to restore or replace such items.

     19.3  Notwithstanding anything to the contrary contained herein, if there
is damage to or a destruction of the Building that exceeds 25% of the
replacement value of the Building, then

                                       21

Lessee shall have the right to terminate this Lease by written notice to Lessor
within forty-five (45) days after the occurrence of such damage or destruction.


                                  ARTICLE XX
                                 CONDEMNATION

     20.1  If the whole or a substantial part (as hereinafter defined) of the
Leased Premises, or the use or occupancy of the Leased Premises, shall be taken
or condemned by any governmental or quasi-governmental authority for any public
or quasi-public use or purpose (including a sale thereof under threat of such a
taking), then this Lease shall terminate on the date title thereto vests in such
governmental or quasi-governmental authority, and all Rent payable hereunder
shall be apportioned as of such date. If less than a substantial part of the
Leased Premises, or if the use or occupancy of less than a substantial part of
the Leased Premises, is taken or condemned by any government or quasi-
governmental authority for any public or quasi-public use or purpose (including
a sale thereof under threat of such a taking) then this Lease shall continue in
full force and effect as to the portion of the Leased Premises not so taken or
condemned, except that as of the date title vests in the governmental or quasi-
governmental authority, Lessee shall not be required to pay Base Rental and
Additional Rental with respect to the portion of the Leased Premises taken or
condemned. For purposes of this Section, a substantial part of the Leased
Premises shall be considered to have been taken if more than twenty-five percent
(25%) of the rentable area of the Leased Premises is rendered unusable as a
result of such condemnation.

     20.2  All awards, damages and other compensation paid by the condemning
authority on account of such taking or condemnation (or sale under threat of
such a taking) shall belong to Lessor, and Lessee hereby assigns to Lessor all
rights to such awards, damages and compensation. Lessee agrees not to make any
claim against the Lessor or the condemning authority for any portion of such
award or compensation attributable to damages to the Leased Premises and
leasehold improvements, except for expenses of leasehold improvements paid for
by Lessee or severance damages. Nothing contained herein, however, shall prevent
Lessee from pursuing a separate claim against the condemning authority for
relocation expenses, the value of furnishings, equipment and trade fixtures
installed in the Leased Premises at Lessee's expense and which Lessee is
entitled pursuant to this Lease to remove at the expiration or earlier
termination of the Lease Term, the value of the unexpired Lease Term, and loss
of profits, provided that such claim shall in no way diminish the award or
compensation payable to or recoverable by Lessor in connection with such taking
or condemnation.

     20.3  Notwithstanding anything to the contrary contained herein, if twenty-
five percent (25%) or more of the Leased Premises or the Building is taken,
condemned, or sold under threat of such a taking, then, whether or not any
portion of the Leased Premises is condemned, Lessee shall have the right, in
Lessee's sole discretion, to terminate this Lease as of the date title vests in
the governmental or quasi-governmental authority.


                                  ARTICLE XXI
                                    DEFAULT

     21.1  The occurrence of any of the following shall constitute a default by
Lessee under this Lease:

     (a)   If Lessee shall fail to pay any payment of Base Rental when due and
     such failure shall continue for a period of ten (10) days after written
     notice from Lessor to Lessee; provided, however, no such written notice
     shall be required for the third and any subsequent failure to pay Base
     Rental before such failure shall constitute a default hereunder.

                                       22
<PAGE>

     (b)  If Lessee shall fail to pay any payment of Additional Rental when due,
     or shall fail to make when due any other payment required by this Lease,
     and such failure shall continue for a period of ten (10) days after written
     notice thereof;

     (c)  If Lessee shall violate or fail to perform any other term, condition,
     covenant or agreement to be performed or observed by Lessee under this
     Lease, and such failure shall continue for a period of thirty (30) days
     after written notice thereof (plus such additional time as is reasonably
     necessary in the event such non-monetary default is incapable of being
     cured in thirty (30) days);

     (d)  If Lessee shall vacate, abandon or fail to continuously occupy the
     Leased Premises or diligently operate its business at the Leased Premises,
     provided that a reduction in the number of Lessee's employees at the Leased
     Premises due to increased automation shall not constitute a default under
     this paragraph (c);

     (e)  An Event of Bankruptcy occurs as specified in Article XXII with
     respect to Lessee;

     (f)  A dissolution of Lessee or liquidation of substantially all of
     Lessee's assets occurs; or

     (g) If any of the following occur with respect to the provisions of Article
     VII of this Lease:

         (i)    Lessee fails to comply with any of the material covenants and
         agreements made by it in Article VII of this Lease or in any Project
         Document;

         (ii)   any representation contained in Section 7.3.1 or in any other
         Project Document is false in any material respect on the date made;

         (iii)  Lessee fails to furnish to Lessor, when requested, copies of
         Drawings and Specifications, shop drawings and technical background
         material, to the extent they have been done, which relate to the
         Expansion;

         (iv)   any of the materials, fixtures or articles used in the
         construction of the Expansion, or to be used in the operation thereof,
         are not in accordance with the Drawings and Specifications;

         (v)    the construction of the Expansion, or any part thereof, shall be
         materially different from the Drawings and Specifications;

         (vi)   Lessee fails to purchase and pay for any of the materials,
         fixtures or articles, to be incorporated in the Expansion, unless
         payment is being properly contested and Lessee shall have bonded over
         or otherwise obtained the release of any lien that may arise in
         connection therewith, to Lessor's satisfaction;

         (vii)  Lessee permits construction of the Expansion to stop for any
         period after its commencement in excess of 15 successive calendar days,
         unless caused by general labor strike, civil disturbance or act of God,
         in which event the following conditions shall be satisfied in order to
         avoid default:

                    (A)  Lessee shall make adequate provision for the protection
                         and security of the Expansion and materials stored on
                         site;

                    (B)  Lessee shall furnish satisfactory evidence that such
                         cessation will not adversely affect the rights of
                         Lessor in any way or of Lessee under any Construction
                         Contract, any other material contract relating to the
                         construction or operation of the Expansion or of the
                         Leased Premises; and

                                       23
<PAGE>

                    (C)  Lessee shall furnish evidence to Lessor that Project
                         Final Completion, if not then achieved, can be achieved
                         on or before the date specified in section 7.3.2(b);

               (viii) Lessee fails to make any deposit with Lessor required by
               this Agreement;

       (ix) any writ, lien, attachment or other encumbrance not approved in
       writing by Lessor is filed against the Leased Premises and remains
       unsatisfied or unbonded for a period of 30 days after the date of filing.

    21.2 If there shall be any default by Lessee under this Lease, Lessor shall
have the right, at its sole option, to terminate this Lease. In addition, with
or without terminating this Lease, Lessor may re-enter, terminate Lessee's right
of possession and take possession of the Leased Premises and the provisions of
this Article shall operate as a notice to quit, any other notice to quit or of
Lessor's intention to re-enter the Leased Premises being hereby expressly
waived. If necessary, Lessor may proceed to recover possession of the Leased
Premises under and by virtue of the laws of the jurisdiction in which the Leased
Premises are located, or by such other proceedings, including re-entry and
possession, as may be applicable. If Lessor does not elect to terminate this
Lease, Lessor also shall have the right, at its sole option, at any time
following a default by Lessee hereunder to terminate all renewal options granted
to Lessee pursuant to this Lease. If Lessor elects to terminate this Lease
and/or elects to terminate Lessee's right of possession, everything contained in
this Lease on the part of Lessor to be done and performed shall cease without
prejudice, subject, however, to the right of Lessor to recover from Lessee all
Rent and other sums accrued up to the time of termination or recovery of
possession by Lessor, whichever is later. If there shall be any default under
this Lease by Lessee, then whether or not this Lease and/or Lessee's right of
possession is terminated by reason of Lessee's default, Lessor may relet the
Leased Premises or any part thereof, alone or together with other premises, for
such term(s) (that may be greater or less than the period that otherwise would
have constituted the balance of the Lease Term) and on such terms and conditions
(that may include concessions or free rent and alterations of the Leased
Premises) as Lessor, in its reasonable discretion, may determine, but Lessor
shall not be liable for, nor shall Lessee's obligations hereunder be diminished
by reason of, any failure by Lessor to relet the Leased Premises or any failure
by Lessor to collect any rent due upon such reletting. If there shall be any
default under this Lease by Lessee, then whether or not this Lease is terminated
by reason of Lessee's default, Lessee nevertheless shall remain liable for any
Base Rental, Additional Rental or damages that may be due or sustained prior to
such default, all reasonable costs, fees and expenses including, but not limited
to, reasonable attorneys' fees, reasonable brokerage fees, expenses incurred in
placing the Leased Premises in first-class rentable condition, and reasonable
costs and expenses incurred by Lessor in pursuit of its remedies hereunder and
in renting the Leased Premises to others from time to time. In addition, Lessee
also shall be liable for an amount equal to Base Rental and Additional Rental
that would have become due during the remainder of the Lease Term, less the
amount of rental, if any, that Lessor receives during such period from others to
whom the Leased Premises may be rented (other than any additional rent received
by Lessor as a result of any failure of such other person to perform any of its
obligations to Lessor), which shall be computed and payable in monthly
installments, in advance, on the first day of each calendar month, following
Lessee's default and continuing until the date on which the Lease Term would
have expired but for Lessee's default. Separate suits or actions may be brought
to collect any such damages for any month(s), and such separate suits or action
shall not in any manner prejudice the right of Lessor to collect any damages for
any subsequent month(s) by similar proceedings, or Lessor may defer any suits or
actions until after the expiration of the Lease Term, in which event Lessee
hereby agrees that such suit or actions shall be deemed not to have accrued
until the expiration of the Lease Term. The provisions contained in this Section
shall be in addition to, and shall not prevent the enforcement of, any claim
Lessor may have against Lessee for anticipatory breach of this Lease.

          21.3  Remedies.  If Lessee shall be in default as defined by Section
                --------
21.1(g) of this Lease and such default shall not be cured within 10 days after
Lessor shall have given Lessee notice of such default,

                (a) Lessor may exercise any right or remedy it has under this
                Lease, any other document, or otherwise available to Lessor at
                law or in equity; and

                (b) Lessor will also have the right to enter and take possession
                of the Leased Premises and take any and all actions necessary in
                its judgment to complete construction of the Expansion,
                including, but not limited to, making changes in the Drawings
                and Specifications and entering into, modifying or terminating
                any contracts, all without any liability whatsoever to Lessee,
                and Lessee hereby expressly waives any rights or claims it may
                hereafter have with respect thereto; and Lessee hereby
                irrevocably appoints Lessor as its attorney-in-fact with full
                power of substitution, to complete the Expansion in Lessee's
                name. In any event, all sums expended by Lessor in completing
                the construction (whether or not contained in the Project
                Budget) and not reimbursed by Lessee or Ceridian Corporation
                will constitute advances of Lessor's Funds, and such expenditure
                by Lessor shall not be deemed to be or constitute a waiver of
                the default giving rise to such expenditure. Notwithstanding the
                foregoing, Lessor shall have the right at any time to
                discontinue any or all work on the Expansion without liability
                to Lessee.

          21.4  All rights and remedies of Lessor set forth in this Lease are in
addition to all other rights and remedies available to Lessor at law or in
equity.  All rights and remedies available to Lessor pursuant to this Lease or
at law or in equity are expressly declared to be cumulative.  The exercise by
Lessor of any such right or remedy shall not prevent the concurrent or
subsequent exercise of any other right or remedy.  No delay or failure by Lessor
to exercise or enforce any of Lessor's rights or remedies or Lessee's
obligations shall constitute a waiver of any such rights, remedies or
obligations, Lessor shall not be deemed to have waived any default by Lessee
unless such waiver expressly is set forth in a written instrument signed by
Lessor.  If Lessor waives in writing any default by Lessee, such waiver shall
not be construed as a waiver of any covenant, condition or agreement set forth
in this Lease except as to the specific circumstances described in such written
waiver.

          21.5  If Lessor shall institute proceedings against Lessee and a
compromise or settlement thereof shall be made, then the same shall not
constitute a waiver of any subsequent default of a similar nature or of any
covenant, condition or agreement set forth herein, nor of any of Lessor's rights
hereunder. Neither the payment by Lessee of a lesser amount than the monthly
installment of Base Rental, Additional Rental or of any sums due hereunder nor
any endorsement or statement on any check or letter accompanying a check for
payment of Rent or other sums payable hereunder shall be deemed an accord and
satisfaction, and Lessor may accept such check or payment without prejudice to
Lessor's right to recover the balance of such Rent or other sums or to pursue
any other remedy available to Lessor. No re-entry by Lessor, and no acceptance
by Lessor of keys from Lessee, shall be considered an acceptance of a surrender
of this Lease.

          21.6  If Lessee defaults in the making of any payment to any third
party or in the doing of any act herein required to be made or done by Lessee,
then Lessor may, but shall not be required to, make such payment or do such act.
The taking of such action by Lessor shall not be considered as a cure of such
default by Lessee or prevent Lessor from pursuing any remedy it is otherwise
entitled to in connection with such default. If Lessor elects to make such
payment or do such act, then all costs and expenses incurred by Lessor, plus
interest thereon at the Default Rate, from the date incurred by Lessor to the
date of payment thereof by Lessee, shall constitute Additional Rental due
hereunder; provided however, that nothing contained herein shall be construed to
permit Lessor to charge or receive interest in excess of the maximum rate then
allowed by law.

                                       25
<PAGE>

     21.7  If Lessee fails to make any payment of Base Rental, Additional Rental
or any other sum due hereunder on or before the date such payment is due and
payable (without regard to any grace period specified in Section 18.1), then
Lessee shall pay to Lessor a late charge of one and one-half percent (1-1/2%) of
the amount of such payment. In addition, such payment and such late fee shall
bear interest at the Default Rate from the date such payment or late fee,
respectively, became due to the date of payment hereof by Lessee; provided,
however, that nothing contained herein shall be construed as permitting Lessor
to charge or receive interest in excess of the maximum rate then allowed by law.
Such late charge and interest shall constitute Additional Rental due hereunder.

     21.8  Lessee hereby expressly waives, for itself and all persons claiming
by, through, or under it, any right of redemption or for the restoration of the
operation of this Lease under any present or future law, including without
limitation any such right that Lessee would otherwise have in case Lessee shall
be dispossessed for any cause, or in case Lessor shall obtain possession of the
Leased Premises as herein provided.


                                 ARTICLE XXII
                                  BANKRUPTCY

     22.1  The following shall be Events of Bankruptcy under this Lease:  (a)
Lessee becoming insolvent, as that term is defined in Title 11 of the United
States Code (the "Bankruptcy Code"), or under the insolvency laws of any state,
district, commonwealth or territory of the United States (the "Insolvency
Laws"); (b) the appointment of a receiver or custodian for any or all of
Lessee's, property or assets or the institution of a foreclosure action upon any
of Lessee's real or personal property; (c) Lessee's filing or consenting to a
petition under the provisions of the Bankruptcy Code or the Insolvency Laws or
in any bankruptcy, reorganization, composition, extension, arrangement or
insolvency proceeding; (d) the filing of a petition against Lessee as the
subject debtor under the Bankruptcy Code or Insolvency Laws, which is not
consented to by such subject debtor and which either (i) is not dismissed within
ninety (90) days of filing, or (ii) results in the issuance of an order for
relief against the debtor; or (e) Lessee's making or consenting to an assignment
for the benefit of creditors or a common law composition of creditors.

     22.2
           (a)  Upon occurrence of an Event of Bankruptcy, Lessor shall have all
           rights and remedies available to Lessor pursuant to Article XXI;
           provided, however, that while a case in which Lessee is the subject
           debtor under the Bankruptcy Code is pending, Lessor shall not
           exercise its rights and remedies pursuant to Article XXI so long as
           both (i) the Bankruptcy Code prohibits the exercise of such rights
           and remedies and (ii) Lessee or its Trustee in Bankruptcy (the
           "Trustee") is in compliance with the provisions of Sections 22.2(b)
           and (c) below.

           (b)  To the extent not prohibited under the Bankruptcy Code, Lessor
           and Lessee agree that in the event Lessee becomes the subject debtor
           in a case pending under the Bankruptcy Code, Lessor's right to
           terminate this Lease pursuant to Section 22.2(a) shall be subject, to
           the extent required by the Bankruptcy Code, to any rights of Trustee
           to assume or assign this Lease pursuant to the Bankruptcy Code.
           Trustee shall not have the right to assume or assign this Lease
           unless Trustee promptly (i) cures all defaults under this Lease (ii)
           compensates Lessor for monetary damages incurred as a result of such
           defaults, (iii) provides adequate assurance of future performance (as
           defined in Section 22.2(c)) on the part of Lessee as debtor in
           possession or on the part of the assignee of Lessee, and (iv)
           complies with all other requirements of the Bankruptcy Code. Lessee
           agrees in advance that this Lease may be terminated by Lessor in
           accordance with Section 22.2(a) if the foregoing

                                       26
<PAGE>

          criteria for assumption or assignment are not met, or if, after such
          assumption or assignment, Lessee, Trustee or such assignee defaults
          under this Lease.

          (c) To the extent not prohibited under the Bankruptcy Code, Lessor and
          Lessee hereby agree in advance that adequate assurance of future
          performance, as used in Section 22.2(b) above, shall mean that all of
          the following minimum criteria must be met: (i) Lessee's gross
          receipts during the thirty (30) day period immediately preceding the
          initiation of the case under the Bankruptcy Code must be equal to or
          greater than the next monthly installment of Base Rental due under
          this Lease; (ii) Both the average and median of Lessee's gross
          receipts (calculated on a monthly basis) during the six (6) month
          period immediately preceding the initiation of the case under the
          Bankruptcy Code must be equal to or greater than the next monthly
          installment of Base Rental due under this Lease; (iii) Lessee must pay
          its estimated pro rata share of the cost of all services provided by
          Lessor (whether directly or through agents or contractors and whether
          or not previously included as part of Base Rental), in advance of the
          performance or provision of such services; (iv) Trustee must agree
          that Lessee's business shall be conducted in a first class manner, and
          that no liquidating sales, auctions, or other non-first class business
          operations shall be conducted on the Leased Premises; (v) Trustee must
          agree that the use of the Leased Premises as stated in this Lease will
          remain unchanged and that no prohibited use shall be permitted; (vi)
          Trustee must agree that the assumption or assignment of this Lease
          will not violate or affect the rights of other tenants in the Leased
          Premises if any; (vii) Trustee must pay to Lessor at the time the next
          monthly installment of Base Rental is due under this Lease, in
          addition to such installment of Base Rental, an amount equal to the
          monthly installments of Base Rental and Additional Rental due under
          this Lease for the next two (2) months thereafter, said amount to be
          held by Lessor in escrow (the "Escrow Account") until either Trustee
          or Lessee defaults in its payment of Rent or other obligations under
          this Lease (whereupon Lessor shall have the right to draw on the
          Escrow Account) or until the expiration or earlier termination of the
          Lease Term (whereupon the funds shall be returned to Trustee or
          Lessee); (viii) Lessee or Trustee must agree to pay to Lessor at any
          time Lessor is authorized to and does draw on the Escrow Account the
          amount necessary to restore the Escrow Account to the original level
          required by Section 22.2(c)(vii); and (ix) all assurances of future
          performance specified in the Bankruptcy Code must be provided.


                                 ARTICLE XXIII
                                 HOLDING OVER

     Provided Lessee gives written notice to Lessor of Lessee's intent not to
exercise any renewal options provided herein or negotiate a new lease for the
Leased Premises, Lessee shall have the right to hold over for a period not
exceeding one (1) year from the expiration of the Lease Term (the "Holdover
Period"). Said right shall be contingent upon Lessor receiving the aforesaid
written notice six (6) months prior to the expiration of the Lease Term, which
notice shall specify the length of the Holdover Period. If Lessee retains
possession of the Leased Premises or any part thereof after the termination of
this Lease, Lessee shall pay Rent (including Base Rental and Additional Rent)
during the six (6) month period commencing upon the termination of the Lease
Term at a rate of one hundred ten percent (110%) of the Rent payable on the last
month of the Lease Term computed on a daily basis for each day that Lessee

equal to twelve (12) on the Building, including additions and improvements by
Lessee. Lessee shall maintain at its expense all risk property insurance on all

replacement cost of the Building as determined by Lessor, including all
additions and improvements made by Lessee and its personal property. Said policy
shall name Lessor and the lender, if any, as additional insureds and loss
payees. In addition, Lessee, shall, at its expense, provide the following
insurance policies for Lessor's benefit: (a) when applicable, flood insurance as
needed to conform with all requirements of the National Flood Insurance Program
as if Lessor had been required to comply with said program, in an amount equal
to the lesser of the estimated replacement cost of the improvements or the
maximum coverage made available by the Federal Insurance Administration, and (b)
any other insurance reasonably required by Lessor that is customarily required
by institutional lenders in similar office developments. Lessee shall furnish
Lessor with a certificate evidencing such coverage that shall contain an
obligation by the insurer to give Lessor and any lenders thirty (30) days prior
written notice of any modification or cancellation of the coverage afforded by
such insurance.

    Beginning on the Commencement Date, Lessee shall maintain commercial general
liability insurance against claims for bodily injury, death or property damage
occurring in, on or about the parking areas, Building or the Leased Premises in
a combined single limit of not less than Two Million and No/100 Dollars
($2,000,000.00) per occurrence. Such insurance shall be effected under policies
satisfactory to Lessor that shall name Lessor and the lender, if any, as an
additional insured thereunder.


                                 ARTICLE XXVI
                            INSURANCE REQUIREMENTS

    Each insurance policy referred to in Articles XXIV and XXV shall: (a) be
issued by a company which is satisfactory to Lessor and which is licensed to
conduct business in the jurisdiction in which the Leased Premises are located;
(b) contain an endorsement that such policy shall remain in full force and
effect notwithstanding the insured may have waived its right of action against
any party prior to the occurrence of a loss, and shall provide that the insurer
waives all right of recovery by way of subrogation against Lessor and the
lender, if any, their agents, employees and representatives in connection with
any loss or damage covered by such policy; (c) be acceptable in form and content
to Lessor; (d) be primary and non-contributory; and (e) contain an endorsement
prohibiting cancellation, failure to renew, reduction of amount of insurance or
change in coverage without the insurer's first giving Lessor and Lessors thirty
(30) days prior written notice of such proposed action. No such policy shall
contain any deductible provision except as otherwise approved in writing by
Lessor. Lessee shall deliver to Lessor a duplicate original of each such policy,
together with a receipt evidencing payment of the premium for such insurance on
or before the Commencement Date and at least annually thereafter. If Lessee is
unable to obtain insurance with the required waiver of subrogation, Lessee may
provide Lessor such additional insurance as will give Lessor the same protection
as if the waiver of subrogation had been obtained.

                         WAIVER OF RIGHTS OF RECOVERY

    Anything in this Lease to the contrary notwithstanding, Lessor and Lessee
each hereby waives any and all rights of recovery, claim, action or cause of
action, against the other, its agents, officers, or employees, for any loss or
damage that may occur to the Leased Premises, or any improvements thereto, or to
the Building, or any improvements thereto, or any personal property of such
party therein, by reason of fire, the elements, or any other cause to the extent
that such loss or damage is covered by insurance, regardless of cause or origin,
including negligence of the other party hereto, its agents, officers or
employees, and each covenants that no insurer shall have any right of
subrogation against such other party.


                                ARTICLE XXVIII
                         SUBORDINATION AND ATTORNMENT

    Lessee agrees that, provided Lessee receives a non-disturbance agreement
which provides that so long as Lessee is not in default under the Lease,
Lessee's leasehold estate, use, possession, tenancy, rights, options, and
occupancy shall remain undisturbed and shall survive any foreclosure, its rights
hereunder shall be subordinate to the lien of any mortgage or the lien resulting
from any other method of financing or mortgages, or refinancing, now or
hereafter in force against the Building and/or the Land and to all advances made
or hereafter to be made upon the security thereof.  Lessee shall, in the event
any proceeding is brought for the foreclosure of, or in the event a deed is
given in lieu of foreclosure of, any mortgage made by Lessor covering the
Building, attorn to the purchaser upon any such foreclosure or sale and
recognize such purchaser as the Lessor under this Lease.

Lessee agrees to pay LaSalle the sums due LaSalle, it being understood that
certain sums payable to LaSalle as identified in the Project Budget shall be

provided out of Lessor's Funds.  Lessee shall indemnify and hold Lessor harmless

arising out of any claim or claims, actions, demands or judgments for brokerage

                                 ARTICLE XXXI
                             ASSIGNMENT BY LESSOR

    Prior to Project Final Completion and the full funding of all of Lessor's
funding obligations in connection therewith, Lessor shall not assign the lease
or its rights thereunder without the prior written consent of Lessee.
Thereafter, Lessor shall have the right to transfer and assign, in whole or in
part, all its rights and obligations hereunder and in the Leased Premises.  In
such event and upon such transfer, no further liability or obligation shall
accrue against the assigning Lessor from the date of such transfer.


                                 ARTICLE XXXII
                           ASSIGNMENT AND SUBLETTING

    32.1  Except as set forth herein, Lessee shall not assign, transfer,
mortgage or otherwise encumber this Lease or all or substantially all or any of
Lessee's rights hereunder or interest herein or sublet all or substantially all
of the Leased Premises, without obtaining the prior written consent of Lessor,
which consent may be withheld or granted in Lessor's sole and absolute
discretion. No assignment or transfer of this Lease or the right of occupancy
hereunder may be effectuated by operation of law or otherwise without the prior
written consent of Lessor. The consent by Lessor to any assignment, subletting
or occupancy shall not be construed as a waiver or release of Lessee from
liability for the performance of any covenant or obligation to be performed by
Lessee under this Lease, nor shall the collection or acceptance of Rent from any
assignee, subtenant or occupant constitute a waiver or release of Lessee from
any of its liabilities or obligations under this Lease. Lessor's consent to any
assignment, subletting or occupancy shall not be construed as relieving Lessee
or any assignee, subtenant or occupant from the obligation of obtaining Lessor's
prior written consent to any subsequent assignment, subletting or occupancy. For
any period during which Lessee is in default hereunder, Lessee hereby assigns to
Lessor the Rent due from any assignee, subtenant, licensee, concessionaire or
occupant of Lessee and hereby authorizes each such assignee, subtenant or
occupant to pay said Rent directly to Lessor.

    32.2  Notwithstanding anything to the contrary contained herein, and
provided Lessee is not in default hereunder, Lessor (a) expressly consents to
Lessee's assignment or subletting of the Leased Premises or any part thereof to
any parent, subsidiary or affiliate of Lessee or of Ceridian Corporation and (b)
agrees not to unreasonably withhold its consent to a subletting of less than
substantially all of the Leased Premises to third parties, provided such
assignment or subletting shall not relieve or release Lessee from any
obligations of Lessee under this Lease.

    32.3  If at any time during the Lease Term Lessee desires to transfer,
assign or sublet all or substantially all of the Leased Premises, then in
connection with Lessee's request to Lessor for Lessor's consent thereto, Lessee
shall give notice to Lessor in writing ("Lessee's Request Notice") of the
identity of the proposed assignee or subtenant and its business, the terms of
the proposed assignment or subletting, and the commencement date of the proposed
assignment or subletting (the "Proposed Sublease Commencement Date").  Lessee
shall also transmit therewith the most recent financial statement or other
evidence of financial responsibility of such assignee or subtenant and a
certification executed by Lessee and such proposed assignee or subtenant stating
whether or not any premium or other consideration is being paid for the proposed
assignment or sublease.

    32.4  (a)  Upon receipt of a Lessee's Request Notice, other than for an
          assignment or subletting to any parent, subsidiary or affiliate of
          Lessee or of Ceridian Corporation pursuant to Section 32.2 hereof,
          Lessor shall have the right in its sole and absolute

                                       31
<PAGE>

          discretion to terminate this Lease by sending Lessee written notice of
          such termination within thirty (30) days after Lessor's receipt of
          Lessee's Request Notice.

          (b) If the Lessor elects to terminate this Lease, then (i) Lessee
          shall tender the Leased Premises to Lessor on the Proposed Sublease
          Commencement Date, and (ii) this Lease shall terminate on the Proposed
          Sublease Commencement Date.

          (c) In no event will Lessee be permitted to assign or sublet less than
          the entire Leased Premises, except as provided in Section 32.2 above.

    32.5  If any sublease, assignment or other transfer (whether by operation of
law or otherwise) provides that the subtenant, assignee or other transferee
thereunder is to pay any amount in excess of the Rent and other charges due
under this Lease, whether such excess be in the form of an increased monthly or
annual rental, a lump sum payment, payment for the sale, transfer or lease of
Lessee's fixtures, leasehold improvements, or any other form (and if the
subleased or assigned space does not constitute the entire Leased Premises, the
existence of such, excess shall be determined on a pro-rata basis), Lessor shall
be paid fifty percent (50%) of any such excess or other premium applicable to
the sublease, assignment or other transfer; it is understood and agreed,
however, that acceptance of any payments by Lessor hereunder shall not be deemed
to constitute approval by Lessor of any sublease, assignment or other transfer,
nor shall such acceptance waive any rights of Lessor hereunder.  Any such
premium shall be paid by Lessee to Lessor as Additional Rental upon such terms
as shall be specified by Lessor and in no event later than ten (10) days after
any receipt thereof by Lessee.  Lessor shall have the right to inspect and audit
Lessee's books and records relating to any sublease, assignment or other
transfer.  Any sublease, assignment or other transfer shall, at Lessor's option,
be effected on forms supplied or approved by Lessor.

    32.6  All restrictions and obligations imposed pursuant to this Lease on
Lessee shall be deemed to extend to any subtenant, assignee, licensee,
concessionaire or occupant of Lessee, and Lessee shall cause such persons to
comply with such restrictions and obligations.

    32.7  Any attempted assignment or sublease by Lessee in violation of the
terms and covenants of this Lease shall be null and void.


                                ARTICLE XXXIII
                                PURCHASE OPTION

    Lessee will have a right to purchase the Leased Premises in accordance with

                                   EXTENSION

    Lessee shall have two (2) options to extend the Lease under the same terms
and conditions as provided herein for consecutive five (5) year terms (the
second to be exercisable only if the first extension option is exercised),
exercisable by providing Lessor written notice (the "Notice") of Lessee's intent
to exercise the extension at least one year prior to the expiration date of the
Lease Term or the applicable option period.  The Base Rental for each renewal
option period shall be calculated in accordance with the formula set forth on
Exhibit D, provided Lessee shall have no obligation to extend pursuant to this
---------
Article XXXIV until the Base Rental for the option period in question is
established and Lessee accepts such rate within sixty (60) days of Lessor's
receipt of the Notice extending said option period.

    Lessee shall provide to Lessor on or before the Expansion Completion Date
statements executed by Gresham Smith and Partners and any inspecting architects
stating that to the best of their knowledge the Expansion is constructed in
accordance with the Plans.


                                 ARTICLE XXXVI
                                   GUARANTY

pursuant to this Lease and in connection herewith are being guaranteed by
Ceridian Corporation, owner of all outstanding stock of Lessee, pursuant to a
Guaranty of Lease in the form of Exhibit Q attached hereto.

representation inducement, warranty, understanding or agreement that is not
