2.  DEMISE AND TERM.  Landlord leases the Premises to Tenant and Tenant leases
the Premises described in section 1.3 above from Landlord subject to the
provisions of this Lease; provided, that any space in the Premises used for
shafts, pipes, conduits, ducts, electrical or other utilities or Building
facilities, as well as access thereto through the Premises for the purposes of
installation, operation, maintenance, inspection, repair and replacement are
reserved to Landlord and are excluded from the Premises, provided that, except
as otherwise set forth herein, Landlord shall not enter the Premises for such
purpose without reasonable prior notice to Tenant and only in the presence of an
authorized representative of Tenant.  The Term of this Lease shall commence on
the Commencement Date set forth in section 1.6 and shall end on the Termination
Date set forth in section 1.7 unless extended or sooner terminated as provided
herein.  Tenant acknowledges that the Commencement Date set forth in section 1.6
is an anticipated date; the actual Commencement Date shall be the date which is
the later of (i) 15 days following the date upon which Landlord shall
substantially complete the remodeling of the Premises as set forth on Exhibit D
attached hereto or (ii) April 1,

                                       2
<PAGE>

2000. If Landlord shall be unable to deliver possession of the Premises to
Tenant on or before March 15, 2000 because Landlord has not sufficiently
completed such remodeling, because of the holding over or retention of
possession of any tenant or occupant, or because of any other reason, Landlord
shall not be subject to any liability for the failure to deliver possession, but
the Commencement Date shall be delayed one day for each day after March 15, 2000
that Landlord does not achieve substantial completion of the remodeling of the
Premises and the Termination Date shall be extended for an equal period plus the
number of days necessary to end the Term on the last day of a month.
Notwithstanding the foregoing, if Landlord's delay in completing the remodeling
of the Premises is due to the fault of Tenant, the Commencement Date shall be
April 1, 2000 and there shall be no extension thereof; further the last sentence
of this section 2 shall not apply. Each party agrees, at the request of the
other, to execute and deliver an instrument confirming the actual Commencement
Date and the Termination Date when determined. Landlord agrees to provide Tenant
with access to the Premises at least 15 days prior to the Commencement Date at
no cost, during which time Tenant shall be permitted (at Tenant's sole risk) to
install Tenant's furniture, communications equipment, card access and security
system and complete Tenant's cabling into work stations, but not to conduct
Tenant's business.

     Notwithstanding the foregoing, Tenant shall have the option to terminate
this Lease effective as of March 31, 2005 on the following terms and conditions:

          (i) Landlord must receive from Tenant no later than March 31, 2004
written notice of Tenant's intent to terminate (a "Termination Notice").

          (ii) The Termination Notice must be accompanied by a payment to
Landlord (the "Termination Fee") equal to the sum of:

               [a] one year of Base Rent for the Premises at the rate in effect
for the period from April 1, 2005 through March 31, 2006; plus

               [b] the entire unamortized principal portion of the Tenant
Improvement Component of the Base Rent for the remainder of the original Lease
term. ((If Tenant exercises any of the expansion options set forth in section 41
of this Lease, the unamortized principal portion of the Tenant Improvement
Component in the Base Rent applicable to such expansion areas shall also be
payable to Landlord.); plus

               [c] the entire unamortized principal portion of all real estate
brokerage commissions paid by Landlord in connection with this Lease (including
payments made in connection with Tenant's exercise of its expansion options)for
the remainder of the original Lease term, with such commissions amortized on the
same basis as the Tenant Improvement Component.

3.  RENT.  Tenant agrees to pay to Landlord at Landlord's address set forth in
section 1.11 or such other place designated by Landlord, without prior demand or
notice, the rent for the Premises consisting of Base Rent set forth in section
3.1 and the Operating Charges set forth in section 3.2 and any other additional
payments due under this Lease.  The obligation of Tenant to pay rent is hereby
declared to be an independent covenant.  Landlord agrees to accept regular
monthly payments of Rent using Automated Clearing House ("ACH") and agrees to
execute such reasonable paperwork as may be necessary to allow such payment
process.

                                       3
<PAGE>

     3.1  Base Rent.  The amount specified in section 1.8 shall be payable in 12
equal installments in advance on the first day of each month during the Term.
In the event the Term commences on other than the first day of a calendar month,
the rent for such partial month shall be prorated based upon the actual number
of days of the Term during such month.  The parties hereto agree that the Base
Rent payable under the terms of this Lease shall be an absolute net return to
Landlord for the Lease Term free from any expense, charge, deduction, offset or
counterclaim by reason of any obligation of Landlord or any other reason and all
of the provisions of this Lease shall be construed and interpreted to such end.

     3.2  Operating Charges.  From and after the Commencement Date, Tenant shall
pay to Landlord, as additional rent, Tenant's Proportionate Share of Operating
Charges (as defined below).  Such additional rent shall be paid within ten days
after demand from Landlord or, at Landlord's option, in advance in monthly
installments on the first day of each calendar month during the Term in an
amount estimated by Landlord from time to time to provide funds sufficient to
pay Tenant's annual obligation for such costs and expenses.  Landlord shall
deliver to Tenant a budget setting forth anticipated Operating Charges for the
remainder of the first calendar year of the term of this Lease (an "Estimated
Budget").  Prior to the commencement of each successive calendar year during the
term of this Lease, Landlord shall deliver to Tenant an Estimated Budget for the
upcoming calendar year.  The Estimated Budget shall set forth the estimated
Operating Charges in reasonable detail with respect to each category of expense.
From time to time during the Term (but not more than once annually), Landlord
may notify Tenant in writing of any reasonable adjustment in the monthly
installments due hereunder, and thereafter Tenant shall make payments
accordingly.  Within ninety days after the expiration of each calendar year, or
as soon thereafter as is reasonably practicable, Landlord shall provide Tenant a
statement in reasonable detail showing the actual amount of additional rent, if
any, payable by Tenant under this section 3.2, and showing the amounts with
respect to the various categories of Operating Charges.  Within ten days after
such notice, Tenant shall pay to Landlord or Landlord shall credit against the
obligations of Tenant or if at the end of the term, refund any excess amounts
paid by Tenant, as the case may be, the difference between the estimated
payments made by Tenant during the prior calendar year and the actual amount of
additional rent due from Tenant as shown on such statement.  Tenant's obligation
for additional rent under this section 3.2 for the year in which the Term
commences and ends shall be prorated based upon the number of days of the Term
during such years.  Tenant's obligation for additional rent under this section
3.2 through the Termination Date and Landlord's obligation to refund any excess
amounts paid by Tenant shall survive termination.

     "Operating Charges" as used herein shall mean all reasonable sums expended
or obligations incurred by Landlord with respect to the Building, whether or not
now foreseen, determined on an accrual basis, including, but not limited to,
real estate taxes, special and/or area assessments and charges then due and
payable (or any substitutes hereafter collected by any governmental authority in
lieu thereof or in addition thereto) and any costs of seeking or obtaining a
reduction or refund thereof; assessments and/or charges under any covenants
and/or easements; salaries, fringe benefits and related costs of employees
engaged on site in operation, maintenance or security; insurance covering
hazards, casualties and potential losses; license, permit and inspection fees; a
management fee not greater than four percent of the gross rent paid by Tenant
and other tenants of the Building; auditors' fees; legal fees incurred in
connection with protesting property taxes; materials and supplies, including
charges for telephone, telegraph, postage and supplies; repairs and maintenance
of the Building, including costs of

                                       4
<PAGE>

materials and supplies; replanting of landscaped areas; landscaping and ground
maintenance; snowplowing and snow removal; costs incurred in connection with the
operation, maintenance, repair, inspection and servicing (including maintenance
contracts) of electrical, plumbing, heating, air conditioning and mechanical
equipment and the cost of materials and supplies used in connection therewith;
cost of services including heat, air conditioning, electricity, gas, water and
sewer and other utilities; all other expenses and costs reasonably necessary or
desirable to be incurred for the purpose of operating, cleaning, securing,
repairing, equipping, supplying and properly maintaining the Building and the
facilities and equipment contained therein and its Common Areas as an office and
warehouse facility, whether or not similar to the foregoing. Operating Charges
shall not include (a) Landlord's cost of utilities or other services, if any,
separately sold by Landlord to tenants or separately metered for the Premises or
other tenant space in the Building, (b) costs incurred by Landlord for any
alterations for other tenants, (c) depreciation of the Building and major
components, (d) debt service on indebtedness of Landlord or rental under any
underlying lease, (e) all costs of a capital nature except for capital
expenditures which reduce other operating expenses (but only to the extent of
the cost savings) or such capital expenditures that are required by changes in
any governmental law or regulation first enacted after the date of this Lease,
in which case such expenditures, plus interest on the unamortized principal
investment at 10% per annum, shall be amortized over the life of the
improvements, (f) future installments of special assessments not yet due and
payable, (g) costs of correcting defects in the design or construction of
improvements included in the Project, (h) broker's commissions and attorneys'
fees (except as specified above), (i) costs related to removal, abatement or
similar actions relating to asbestos or Hazardous Substances located on, under
or about the Project, (j) costs incurred because Landlord or another tenant
violated the terms of any lease or any law and any enforcement costs, (k) any
expense for which Landlord is reimbursed by insurance or otherwise, and (l) any
expenses that are not reasonable, actual, necessary and obtained at competitive
prices.

          If Tenant shall not dispute any item or items shown on Landlord's
statement within 60 days after such notice, Tenant shall be deemed to have
approved such statement and shall be estopped from contesting such statement or
the amount due. Tenant and its agents and representatives shall have the right
upon reasonable notice to inspect and review Landlord's books and records with
respect to Operating Charges. If Tenant shall dispute any item or items
included by Landlord in determining Operating Charges, Tenant shall nevertheless
pay to Landlord in full the amount claimed by Landlord and shall not offset or
withhold any payment while its dispute is pending, and Tenant's payment thereof
shall not preclude a later objection thereto.  If such dispute is not amicably
settled between Landlord and Tenant within 30 days after such notice, either
party may during the 15 days after the expiration of such 30 day period refer
such disputed item or items to a reputable firm of independent certified public
accountants reasonably approved by Landlord and Tenant for resolution, and the
decision of such firm shall be conclusive and binding upon Landlord and Tenant.
The expenses involved in such determination shall be borne by the party against
whom a decision is rendered by such accountants, provided that if more than one
item is disputed and the decision shall be against each party in respect to any
item or number of items disputed, then the expenses shall be apportioned
according to the monetary value of the items decided against each party.
Further, in no event shall Landlord be responsible for the costs incurred in
such determination in excess of the amount by which Tenant's share of Operating
Charges is reduced.

                                       5

          Tenant acknowledges that certain costs and services such as insurance,
security, landscaping, snow plowing and maintenance may be incurred or performed
on a Project-wide basis and that an equitable allocation of the cost thereof
will be made to the various buildings within the Project.  If during all or any
portion of any calendar year the Building is not at least 95% rented and
occupied, Landlord shall make an appropriate adjustment to any components of the
Operating Charges which vary due to changes in occupancy levels (including, but
not limited to, janitorial services, water, sanitary sewer, common utilities and
common services in operating the Building) for such year, employing sound
accounting and management principles, to determine the Operating Charges that
would have been paid or incurred by Landlord had the Building been 95% rented
and occupied and the amount so determined shall be deemed to have been the
Operating Charges for such year.  If any Operating Charge, though paid in one
year, relates to more than one calendar year, such expense shall be
proportionately allocated among such related calendar years.

          If Landlord receives a refund of real estate taxes that were included
in Tenant's pro rata share of Operating Charges paid by Tenant, then Landlord
shall credit against the obligation of Tenant (or if at the end of the term,
reimburse Tenant) Tenant's pro rata share of the refunded taxes. This obligation
shall survive the expiration or termination of this Lease.

          Notwithstanding any provision to the contrary, any annual increase in
the pro rata share of Operating Charges for the Premises shall not exceed 5% of
the prior year's pro rata share of actual Operating Charges for the Premises.

     3.3  Personal Property Taxes.  Tenant agrees to timely pay when due all
personal property taxes, whether assessed against Landlord or Tenant, on
Tenant's furniture, equipment and other items of personal property owned by
Tenant and located in or about the Premises.

     3.4  Late Charge.  Tenant acknowledges that late payment of rent (Base Rent
or additional rental) involve additional costs to Landlord for collection and
bookkeeping, and, accordingly, Tenant agrees that, if rent (Base Rent or
additional rental) due hereunder is not paid by the fifth day after it is due,
then Tenant shall pay upon demand, as additional rent, a late charge equal to 5%
of the amount required to be paid.  The foregoing provision for payment of a
late charge shall not be construed to extend the date for payment of any sums
required to be paid by Tenant hereunder or to relieve Tenant of its obligation
to pay all such sums at the time or times herein stipulated, and neither the
demand for, nor collection by, Landlord of such late charge shall be construed
as a cure of Tenant's default in the payment of rent.

4.  Intentionally left blank.

5.  CONDITION OF PREMISES.  Prior to March 15, 2000, Landlord shall
substantially complete the work of remodeling the Premises which is identified
and described on Exhibit D attached hereto.  If the cost of such work is less
than $1,021,555, then the Base Rent shall be adjusted in accordance with the
formula set forth in section 1.8.2, above.  If Tenant requests changes to the
work that increase the cost thereof, Landlord shall not be obligated to
accommodate such changes unless Tenant pays the amount of increased costs in
advance.  All such work shall be done in a good and workmanlike manner in
compliance with all building codes and regulations.  Upon substantial
completion, the Premises and Building shall be in compliance with all applicable
codes, laws, rules and

                                       6
<PAGE>

ordinances, including without limitation the Americans With Disabilities Act.
Except as specifically provided above, Landlord shall not be required to perform
any improvements or to rework, remodel or recondition the Premises in any manner
whatsoever for Tenant's use and occupancy thereof. Tenant's taking possession of
the Premises shall be conclusive evidence that Tenant accepts the Premises and
that they are in satisfactory condition except for any punch list of
unsatisfactory items of which Tenant gives written notice to Landlord within 30
days after the Commencement Date and except for latent defects. Punch list items
shall be corrected or repaired by Landlord in a timely manner. Latent defects
shall be corrected or repaired by Landlord promptly after Tenant's notice to
Landlord of Tenant's discovery thereof. Tenant, at Tenant's sole cost and
expense, shall perform all other alterations, improvements and other work
necessary to prepare the Premises for Tenant's use. All such work shall be done
in accordance with section 13 below.

6.  USE.  The Premises shall be used only for the purpose set forth in section
1.10 above and for no other purposes without Landlord's prior written consent,
which shall not be unreasonably withheld.  Tenant shall have seven days a week,
24 hours a day access to the Project, Building and Premises.  Tenant expressly
acknowledges that it shall be the sole responsibility of Tenant to secure all
necessary and appropriate permits, licenses and approvals from all governmental
authorities having jurisdiction for the operation of Tenant's business, if any.
It shall be Landlord's responsibility to obtain any necessary certificate of
occupancy with respect to Tenant's occupancy of the Premises.  Tenant shall not
do or permit anything to be done in or about the Premises which in any way will
obstruct or interfere with the rights of any other occupants of the Project, or
use or allow the Premises to be used for any improper, immoral, unlawful or
objectionable purpose or which could injure the reputation of the Project or
otherwise violate any recorded covenant or restriction affecting the Project.
Landlord represents and warrants that Tenant's use for its data service business
will not violate such recorded covenants and restrictions.  Tenant shall not
cause or maintain or permit any nuisance or commit or suffer the commission of
any waste in, on or about the Project.  Tenant expressly acknowledges and agrees
that the foregoing covenant is a material inducement for Landlord to enter into
this Lease and that since damages for breach of such covenant will be difficult
to ascertain, such covenant shall be enforceable by injunction.

7.  COMPLIANCE WITH LAWS AND BUILDING RULES.  Tenant shall, at its sole cost and
expense, promptly comply with all laws, statutes, ordinances and governmental
rules, regulations or requirements now or hereafter in force, and with the
requirements of the local Board of Fire Underwriters or any similar body now or
hereafter constituted relating to or affecting the manner of Tenant's occupancy
and use of the Premises; provided, however, Tenant shall have no obligation to
make capital repairs or improvements in order to achieve compliance except if
the requirement for compliance arises because of the particular use by Tenant of
the Premises as opposed to general office use or arises as a result of
improvements or alterations made by Tenant.  Tenant shall also observe and
comply with the requirements of all policies of insurance at any time in force
with respect to the Project, and Tenant shall not do or permit anything to be
done on or about the Project or bring or keep anything there which will in any
way increase the cost of any insurance now or thereafter carried on the Project
or any of its contents or that will invalidate any such insurance.  Tenant shall
also comply with the Rules and Regulations attached to this Lease as Exhibit C
and such other reasonable rules and regulations to regulate the use, occupancy
and operation of the Project which may from time to time be established by
Landlord in writing,

                                       7
<PAGE>

and any reasonable modifications or amendments thereto (the "Building Rules"),
provided such Building Rules are applied and enforced uniformly to all tenants
of the Project. Landlord shall not be responsible to Tenant for the
noncompliance of other tenants or occupants with the Building Rules. The
provisions of this Lease shall supersede any contrary provision in the Building
Rules.

8.  ENVIRONMENTAL REQUIREMENTS.  With respect to Tenant's use and occupancy of
the Premises, Tenant shall comply with all applicable federal, state and local
environmental laws, ordinances and all amendments thereto and rules and
regulations implementing the same, together with all common law requirements,
which relate to discharge, emissions, waste, nuisance, pollution control,
hazardous substances and other environmental matters as the same shall be in
existence during the Lease Term.  All of the foregoing laws, regulations and
requirements are hereinafter referred to as "Environmental Laws".  Tenant shall
obtain all environmental licenses, permits, approvals, authorizations,
exemptions, certificates and registrations (hereinafter collectively referred to
as "Permits") and make all applicable filings required of Tenant under the
Environmental Laws required by Tenant to operate at the Premises.  The Permits
and required filings shall be made available for inspection and copying by
Landlord at Tenant's offices upon reasonable notice and during business hours.
Tenant shall not cause or permit any flammable explosive, oil, contaminant,
radioactive material, hazardous waste or material, toxic waste or material or
any similar substance which is or may become regulated under any applicable
federal, state or local law (hereinafter collectively referred to as "Hazardous
Substances") to be brought upon, kept or used in or about the Premises except
for small quantities of such substances as is necessary in the ordinary course
of Tenant's business, provided that Tenant shall handle, store, use and dispose
of any such Hazardous Substance in compliance with all applicable laws and the
highest standards prevailing in the industry for the storage and use of such
substances or materials, in a manner which is safe and does not contaminate the
Premises.  It is understood however that Tenant shall have the right to install
at its option an emergency back-up generator and at its option a diesel fuel
tank which falls in the category of Hazardous Materials and requires reporting
under the SARA Act.  If any lender or governmental agency shall ever require
testing to ascertain whether or not there has been any release of any Hazardous
Substance, then the reasonable costs thereof shall be reimbursed by Tenant to
Landlord upon demand as additional rent if such requirement applies to the
Premises as a result of a release of a Hazardous Substance caused by Tenant.
Tenant shall, from time to time, at Landlord's request, execute such other
affidavits, representations and the like concerning Tenant's best knowledge and
belief regarding the presence of Hazardous Substances on the Premises.  Tenant
hereby agrees to indemnify and hold Landlord harmless from any liability, claim
or injury, including reasonable attorneys' fees, and the cost of any required or
necessary repair, cleanup, remediation or detoxification, arising out of (a) the
installation, use, maintenance and operation of the back-up generator, (b) the
use, manufacture, handling, storage, disposal or release of any Hazardous
Substances by Tenant, its agents and employees on, under or about the Premises,
or (c) an actual or alleged violation of Environmental Laws in connection with
the occupancy of the Premises by Tenant or any occupant of the Premises or the
operation of Tenant's business on the Premises during the Lease Term.  Landlord
shall indemnify and hold Tenant harmless from any liability, claim or injury,
including reasonable attorneys' fees and the cost of any required or necessary
repair, cleanup, remediation or detoxification arising out of the presence or
release of Hazardous Substances, the presence or release of which was not caused
by Tenant or its employees, agents or contractors.  The foregoing covenants and

                                       8
<PAGE>

indemnification shall survive the expiration or termination of the Term of this
Lease.

9.  COMMON AREAS.  Tenant and its employees, customers and invitees shall have
the reasonable nonexclusive right to use, in common with Landlord and the other
tenants and occupants of the Project and their respective employees, customers
and invitees and all others to whom Landlord has or may hereafter grant rights
to use the same, the public portion of the Common Areas as may from time to time
exist.  Landlord shall have the right to close any or all portions of the Common
Areas to such extent as may, in Landlord's opinion, be necessary to prevent a
dedication thereof or the accrual of any rights to any person or the public
therein.  Landlord shall at all times have full control, management and
direction of the Common Areas.  Tenant shall not cause or allow any storage of
materials or equipment outside of the Premises on any of the Common Areas.
Landlord reserves the right at any time and from time to time to reduce,
increase, enclose or otherwise change the size, number, location, layout and
nature of the Common Areas, to construct additional buildings and stories, to
create additional rentable areas through use and/or enclosure of Common Areas,
to close portions of the Common Areas for maintenance, repair or replacement, to
place signs in the Common Areas and on the Building or in the Project, to change
the name of the Project or the Building and to change the nature of the use of
any portion of the Project or the Building, provided that none of the foregoing
shall unreasonably interfere with Tenant's use, occupancy or enjoyment of the
Premises.

10.  PARKING.  Tenant and Tenant's employees, customers and invitees shall have
the nonexclusive right to use the parking spaces located within the Common
Areas.  Landlord shall provide Tenant with unreserved  parking spaces sufficient
for 350 employees at the Premises (only employees who occupy the Premises).
Landlord reserves the right to reasonably regulate parking within the Common
Areas, including the right to preclude Tenant from parking in certain parking
spaces.  Tenant shall not permit vehicles to be abandoned or stored in the
parking areas of the Project.

11.  REPAIRS.  Landlord shall maintain the Common Areas and the exterior walls,
roof and foundation of the Building and the heating, ventilating, air
conditioning, electrical, plumbing and mechanical systems provided by Landlord
in the Building, the cost of which shall be included in Operating Charges.
Except as set forth herein, Tenant shall, at its expense, keep the Premises and
every part thereof, in good condition and repair, and Tenant shall also be
responsible for the entire cost of all repairs and replacements otherwise the
responsibility of Landlord hereunder that are required by reason of acts or
negligence of Tenant, its agents, employees, customers or invitees, or the
particular nature of Tenant's use of the Premises (as opposed to general office
use).  Tenant shall be responsible for repairing any damage to the Building
caused by the installation or moving of Tenant's furniture, equipment and
personal property.  Tenant shall, at its expense, also repair or replace with
glass of equal quality any broken or cracked plate or other glass in doors,
windows and elsewhere in or adjacent to the Premises (except for exterior glass
which is subject to reimbursement as provided in section 3.2 of this Lease shall
be repaired by Landlord).  Tenant shall not defer any repairs or replacements to
the Premises (except those due to normal wear and tear) by reason of the
anticipation of the expiration of the Term.  Landlord, at Landlord's option, but
only after Tenant's failure to correct same within 30 days after written notice
to Tenant of its failure, may elect to perform all or part of the maintenance,
repairs and servicing which is the obligation of Tenant hereunder which Tenant
failed to do, and/or the obligation of all of the other tenants of the Project
with respect to

                                       9
<PAGE>

the premises occupied by them, in which event the costs thereof shall be billed
directly to and paid by Tenant or such other tenants as the case may be as
additional rent. Except as aforesaid, in the event that, at the request of
Tenant, Landlord performs any maintenance, repairs or servicing of the Premises
which is the obligation of Tenant hereunder, then Tenant shall pay Landlord
directly therefor.

12.  UTILITIES.  Landlord shall provide interior janitorial services in the
Premises five days per week, except holidays, pursuant to the Schedule attached
as Exhibit E, and the costs therefor shall be paid for by Tenant as additional
rent.  Tenant shall pay for such services within ten days after receipt of the
bill for such services.  Janitorial services to any tenant space in the Building
shall not be included in Operating Charges.  Landlord shall furnish water,
sanitary sewer, heating, air conditioning and ventilating for the permitted use
of the Premises to maintain comfortable temperatures and the cost of such
services shall be included in Operating Charges.  Heating, ventilating and, from
May 1 through September 15 of each year, air conditioning service, shall be
provided seven days a week, 24 hours a day.  Landlord shall cause at Landlord's
expense electricity for the Premises to be separately metered.  It is understood
that Operating Charges shall not include electricity charges for any tenant
space.  Tenant shall be responsible for obtaining its own telephone service, and
Tenant shall timely pay for its separately metered electricity and telephone
service as and when payment are due.

     In no event shall Landlord be liable for damages, nor shall the rental
herein reserved be abated or subject to offset or deduction for failure to
furnish or any delay in furnishing any utility services nor shall the temporary
failure to furnish any of such services be construed as an eviction of Tenant or
relieve Tenant from the duty of observing and performing all of the provisions
of this Lease, provided, however, Landlord shall make all reasonable efforts to
promptly restore such service to the Premises, and in the event of an
interruption of an essential service which is in Landlord's reasonable control
which continues for 72 consecutive hours and as a result of said interruption,
Tenant is not able to operate its business from the Premises, then all Rent
shall abate from the date of said interruption until the essential service is
restored.  Tenant shall not use any apparatus or device in the Premises which
will in any way increase the amount of water or sewer usually furnished,
consumed or supplied for use of the Premises as general office and warehouse
space.  In the event that Tenant requires water or sewer use in excess of that
usually supplied for use of the Premises as general office and warehouse space,
then Tenant shall first procure the written consent of Landlord for such use,
which consent Landlord may grant or withhold in its sole discretion, and Tenant
shall pay additional rent for such services at a rate to be determined by
Landlord in its reasonable discretion or Landlord may require Tenant to install
a submeter, at Tenant's cost, to measure such usage.  In the event that Tenant
desires air conditioning during times in addition to those set forth above,
Landlord shall provide the same and Tenant shall pay therefor as additional rent
at a rate to be determined by Landlord in its sole discretion.  Tenant agrees
not to connect any apparatus or device to the cooling or heating system of the
Building for the purpose of using additional or unusual amounts of such air
conditioning and heating services without the prior written consent of Landlord.
Landlord agrees that Landlord shall not change the electric service provider for
the Premises without first consulting with and addressing any reasonable service
concerns of Tenant.

13.  ALTERATIONS.  Except as permitted hereunder, Tenant shall not make any
alterations, additions or improvements ("Alteration") in, on or to the Premises

                                       10
<PAGE>

or any part thereof without delivering to Landlord the plans and specifications
therefor and obtaining the prior written consent of Landlord.  Landlord's
consent to an Alteration may be granted or withheld in its sole discretion or
may be made contingent upon Tenant agreeing to such conditions relating thereto
as Landlord may impose.  Any Alteration shall be made at Tenant's own cost and
expense and in a good and workmanlike manner in accordance with the laws,
ordinances and codes relating thereto and free from any claim or claims for
construction liens, and Tenant shall indemnify and hold Landlord harmless from
and against any and all claims, liens, costs and expenses on account of such
work.  Upon completion of any Alteration, Tenant shall provide Landlord with a
copy of any as-built plans and blueprints produced for the same.  Landlord
hereby consents to the installation by Tenant of a roof-top satellite for
Tenant's exclusive use (provided that the plans, specifications and location
shall be acceptable to Landlord and the operation and maintenance of such
satellite shall not interfere with the rights of any other tenant on the roof-
top), Tenant's card access and security system and such cabling and wiring as
necessary from time to time for the operation of Tenant's business.

14.  SIGNS.  Tenant shall not install, affix or place any sign or other
advertising or identifying media upon the exterior of the Premises or the
Building or upon the interior or exterior of the windows of the Premises without
first obtaining the written consent of Landlord in each instance.

15.  LIENS.  Except with respect to the construction described in Exhibit D,
Tenant shall not create or permit any liens under any construction lien law to
be filed or recorded against the Premises or against the interest of Landlord or
Tenant therein.  If any such lien is filed or recorded, Tenant shall immediately
cause such lien to be discharged of record.  This provision shall not apply to
any work performed by Landlord unless such work was performed on Tenant's behalf
and was to be paid for by Tenant.

16.  RIGHT OF ENTRY.  Except in the event of an emergency, in which case prior
notice shall not be required, Landlord and its agents shall upon reasonable
prior notice to Tenant and in the presence of an authorized representative of
Tenant, at all times have the right to enter the Premises to inspect the
condition thereof, to supply any service to be provided by Landlord to Tenant
hereunder, to show the Premises, and to alter, improve, or repair the Premises
and any portion of the Building.  Tenant shall not add or change the locks to
any doors of the Premises except in connection with its card access and security
system.  Tenant agrees to deposit or permit Landlord to deposit on Tenant's
behalf a key to the Premises in a lock box if required by and for the benefit of
the local fire department.  Any entry to the Premises shall not under any
circumstances be construed or deemed to be a forcible or unlawful entry into, or
a detainer of, the Premises, or an eviction, of Tenant or impose any liability
on Landlord.  Nothing contained herein shall be deemed to impose on Landlord any
obligation or duty to make repairs or alterations to the Premises except as
expressly provided in this Lease.

17.  INSURANCE.  Tenant shall, at its expense obtain and carry at all times
during the Term of this Lease (a) commercial general liability insurance with
respect to the Premises, including contractual liability coverage for the
indemnification obligations of Tenant contained in this Lease covering injury to
or death of persons and damage to property in an amount not less than
$2,000,000.00 combined single limit per occurrence, and (b) property damage
insurance with extended coverage, vandalism and malicious mischief and theft and
mysterious disappearance endorsements, covering the equipment, personal property
and other

                                       11
<PAGE>

contents of the Premises and all alterations, additions and leasehold
improvements (except the build-out described in Exhibit D attached hereto) made
by or for Tenant in the amount of their full replacement value.  All such
policies shall be written by  a responsible insurance company or companies
licensed to issue insurance in the State of Wisconsin and with an A.M. Best
rating of A, Class IX, or better, shall name Tenant and include Landlord as an
additional insured, as their interests may appear, and shall contain a clause
that the insurer will not cancel or change the insurance coverage without at
least 30 days' prior written notice to Landlord.  Evidence of such insurance
shall be furnished to Landlord when requested.  Such insurance may be furnished
by Tenant under any blanket policy carried by it or under a separate policy
therefor.  Landlord may at any time and from time to time inspect and/or copy
any and all insurance policies required to be procured by Tenant under this
Lease.

18.  WAIVER OF SUBROGATION.  Each party hereby expressly releases the other for
liability it may have on account of any loss to the Premises or Building or
contents of either due to fire or any peril included in the coverage of any
applicable fire and extended coverage and material damage insurance, however
caused, including such losses as may be due to the negligence of the other
party, its agents or employees, but only to the extent of any amount recovered
by reason of such insurance, and each party hereby waives any right of
subrogation which might otherwise exist in or accrue to such party on account
thereof, provided that such release of liability and waiver of the right of
subrogation shall not be operative in any case where the effect thereof is to
invalidate such insurance coverage under applicable state law (or increase the
cost thereof, unless the other party reimburses the insured for any cost
increase).  If Tenant or Landlord fails to maintain in force any insurance
required by this Lease to be carried by it, then for purposes of this waiver of
subrogation it shall be deemed to have been fully insured and to have recovered
the entire amount of its loss.

19.  INDEMNITY.  Except if caused by the negligence or willful acts or omissions
of Landlord or its agents, employees, or contractors, Tenant hereby indemnifies
Landlord and agrees to save it harmless from and against any and all claims,
actions, damages, liability and expense in connection with loss of life,
personal injury and/or damage to property arising from or out of any occurrence
in, upon or at the Premises or by reason of any breach or default by Tenant in
the performance of any term of this Lease on Tenant's part to be performed.  In
case Landlord shall be made a party to any litigation arising out of any such
occurrence, then Tenant shall protect and hold Landlord harmless and shall pay
all costs, expenses and reasonable attorneys' fees incurred or paid by Landlord
in connection with such litigation.  Except if caused by the negligence or
willful acts or omissions of Tenant, or its agents, employees or contractors,
Landlord hereby indemnifies Tenant and agrees to save it harmless from and
against any and all claims, actions, damages, liability and expense in
connection with loss of life, personal injury and/or damage to property arising
from or out of any occurrence in, upon or at the Common Areas or by reason of
any breach or default by Landlord in the performance of any term of this Lease
on Landlord's part to be performed.  In case Tenant shall be made a party to any
litigation arising out of any such occurrence, then Landlord shall protect and
hold Tenant harmless and pay all costs, expenses and reasonable attorneys' fees
incurred or paid by Tenant in connection with such litigation.  Tenant's and
Landlord's obligations under this section shall survive the termination of this
Lease.

20.  NON-LIABILITY OF LANDLORD.  Except for the negligence or willful acts or
omissions of Landlord or its agents, employees or contractors, Landlord

                                       12
<PAGE>

shall not be liable to Tenant, and Tenant hereby waives all claims against
Landlord, for any injury or damage to any person or property in or about the
Project resulting from the Project, Building or Premises, or any part thereof,
or any equipment thereof becoming out of repair; flooding of basements or other
areas; damages caused by sprinkling devices, air conditioning apparatus, snow,
frost, water leakage, steam, excessive heat or cold, falling plaster, broken
glass, sewage, gas, odors or noise or the bursting or leaking of pipes or
plumbing fixtures; or any act or neglect of other tenants or occupants in the
Project or their respective employees, contractors or invitees. Except for the
negligence or willful acts or omissions of Landlord or its agents, employees or
contractors, all property in or about the Project or in the Premises belonging
to Tenant, its agents, employees or invitees shall be there at the risk of
Tenant or other person only, and Landlord shall not be liable for damage thereto
or theft, misappropriation or loss thereof.  If Landlord shall fail to perform
any covenant or condition of this Lease upon Landlord's part to be performed,
and, as a consequence of such default, Tenant shall recover a money judgment
against Landlord, such judgment shall be satisfied only out of the proceeds of
sale received upon execution of such judgment and levy thereon against the
right, title and interest of Landlord in the Project and out of rents or other
income from such property receivable by Landlord, and Landlord shall not be
personally liable for any deficiency.

21.  CASUALTY.  If the Premises or the Building is damaged or destroyed by fire
or other casualty covered by insurance, then (unless this Lease is terminated as
hereinafter provided) this Lease shall continue in full force and effect and
Landlord shall proceed, after adjustment of such loss, to repair or restore the
Premises to the condition which Landlord furnished to Tenant upon the
commencement of the Term.  Landlord shall be under no obligation to restore any
Alterations to the Premises made by Tenant unless the same is covered by
Landlord's insurance, but nothing herein shall be construed to require Landlord
to insure such property.  In no event shall Landlord be obligated to expend an
amount in excess of the insurance proceeds available to Landlord for such repair
or restoration.  In the event the Premises are repaired as provided herein, then
Tenant shall repair and restore its furnishings, furniture, equipment and
personal property to at least a condition equal to that prior to its damage.  If
the Premises or any part thereof shall be rendered untenantable by any
destruction or damage, then a pro rata portion of all rent based upon the number
of square feet of area in the Premises which are untenantable shall be abated
until the Premises or such part thereof shall have been put in tenantable
condition.  Notwithstanding the foregoing, if any destruction or damage to the
Premises, Building or Project (whether or not the Premises are affected) is so
extensive that Landlord, in its reasonable discretion, elects not to repair or
restore the Premises, Building or Project, or the proceeds of insurance are not
sufficient or available to fully pay the cost of the repair or restoration, then
Landlord may terminate this Lease effective as of the date of the damage by
written notice to Tenant given within thirty (30) days after the date of such
casualty.  Notwithstanding any provision to the contrary Landlord shall, within
thirty (30) days after the date of any damage or destruction to the Premises or
access thereto, advise Tenant in writing as to the reasonably estimated time
within which the damage or destruction will be repaired or restored.  If more
than 40% of the square footage of the Premises has been rendered untenantable
and if Landlord reasonably estimates that such damage or destruction cannot be
repaired within one hundred eighty (180) days from the date of the damage, then
Tenant may, by written notice to Landlord within fifteen (15) days after the
receipt of Landlord's notice estimating a time for restoration, elect to
terminate this Lease.  The provisions of this Paragraph are subject to the
rights of Landlord's mortgagees, if any.

                                       13
<PAGE>

22.  CONDEMNATION.  If all or substantially all of the Premises are sold to or
taken by any public authority under its power of condemnation or the threat
thereof, this Lease shall terminate as of the date possession shall be
transferred to the acquiring authority, and the rental payable hereunder shall
be apportioned accordingly.  If any material part of the Project is sold or
taken (whether or not the Premises are affected), Landlord shall have the right
to terminate this Lease as of the date possession is transferred to the
acquiring authority upon giving written notice thereof to Tenant, and the rental
payable hereunder shall be apportioned accordingly.  In the event this Lease is
not terminated pursuant to this section 22, then this Lease shall continue in
force as to the part of the Premises not taken and the rent payable thereafter
shall be reduced in proportion to the amount of total floor area of the Premises
taken, provided however, Tenant may terminate this Lease upon written notice to
Landlord if as a result of a partial taking, Tenant reasonably determines it is
no longer feasible to operate its business from the remaining Premises.  In the
event of any such taking, Landlord, upon receipt and to the extent of the award
in condemnation or proceeds of sale, shall, unless this Lease has been
terminated, make necessary repairs and restorations (exclusive of Tenant's
leasehold improvements and Alterations made subsequent to Commencement Date) to
restore the Premises remaining to as near its former condition as circumstances
will permit.  All damages awarded by or amounts paid by the acquiring authority
for any such taking, whether for the whole or a part of the Premises or the
Building, Common Areas or Project shall belong to and be the sole property of
Landlord whether such damages are awarded as compensation for loss of, or
diminution in value to, the leasehold or the fee thereof, provided, however,
Tenant shall have the right to pursue such claim or claims as Tenant may have
legally for relocation expenses, interruption of business and such items such as
trade fixtures and equipment, which do not reduce the award or proceeds of sale
payable to Landlord.  In the event that this Lease is terminated, Tenant shall
not have any claim against Landlord for the value of the unexpired term hereof.
The provisions of this section are subject to the rights of Landlord's
mortgagees, if any.

23.  ASSIGNMENT AND SUBLETTING.  Except as permitted below, Tenant shall not
assign, pledge, mortgage or otherwise transfer or encumber this Lease or sublet
any part or all of the Premises and shall not permit any use of any part of the
Premises by any other party, or any transfer of its interest in the Premises by
operation of law, without the prior written consent of the Landlord, which
consent shall not be unreasonably withheld or delayed.  The following shall be
deemed to be an assignment of this Lease within the meaning of this Paragraph:
(a) the sale, issuance or transfer of any voting stock of Tenant (if Tenant is a
nonpublic corporation or if Tenant is a public corporation and such sale,
issuance or transfer results in Tenant becoming a nonpublic corporation) which
results in a change in voting control of Tenant; (b) the sale, issuance or
transfer of any partnership or membership interest in Tenant if Tenant is a
partnership or limited liability company; (c) the change or conversion of a
general or limited partnership to a limited liability company, limited liability
partnership or any other entity which possesses the characteristics of limited
liability; (d) the sale, issuance or transfer of any beneficial interest in
Tenant if Tenant is a trust; and (e) the death or incapacity of Tenant if Tenant
is a natural person.  Without waiving Landlord's right hereunder to declare a
default in the event of an assignment of this Lease or a subletting of the
Premises or any part thereof or occupancy of the Premises by anyone other than
Tenant, Landlord may collect from the assignee, sublessee or occupant, any
rental and other charges herein required, but such collection by Landlord shall
not be deemed an acceptance of the assignee, sublessee or occupancy, nor a
release of Tenant from the performance by Tenant of this Lease.

                                       14
<PAGE>

Further, Tenant at all times and under all circumstances shall remain liable to
Landlord for the payment of rent due and to become due and the performance of
all other obligations of Tenant hereunder for the term hereof. Tenant shall pay
to Landlord, as additional rent, any reasonable costs and expenses including
attorneys' fees incurred by Landlord in connection with its consent to any
proposed or purported assignment, sublease or other transfer. Subject only to
Landlord's prior reasonable review and approval of the creditworthiness of the
successor tenant, Tenant shall have the right to assign this Lease or sublet the
Premises in whole or in part to an entity affiliated with Tenant or in
connection with mergers, consolidations or the sale or transfer of all or
substantially all of the assets or stock of Tenant or the division or the
operating business unit occupying the Premises.

24.  DEFAULT.  If (a) Tenant (i) shall fail to pay the rent or any charge due
hereunder within five days after Landlord notifies Tenant in writing that such
amount is delinquent or, (ii) if Landlord has within the preceding 12-month
period previously delivered such a written notice of delinquency to Tenant,
Tenant shall fail to pay the rent or any charge due within five days after the
same is due, or (b) Tenant shall fail to perform any of the other covenants or
conditions herein contained on the part of Tenant, and such default shall
continue for thirty days after written notice thereof shall have been given to
Tenant (except that such thirty day period shall automatically be extended for
an additional period of time, up to a maximum of ninety days, reasonably
necessary to cure such default, if such default cannot be cured within such
thirty day period and provided Tenant commences the process of curing such
default within said thirty day period and diligently pursues such cure to
completion), or (c) except as permitted by this Lease, if this Lease shall, by
act of Tenant or by operation of law or otherwise pass to any party other than
Tenant, or (d) if Tenant shall abandon or vacate the Premises or permit the
Premises to become vacant without paying the rent or any charges required by
this Lease, or (e) Tenant or any guarantor of this Lease shall become insolvent
or bankrupt or make an assignment for the benefit of creditors, or (f) a
receiver or trustee of Tenant's property or that of any guarantor of this Lease
shall be appointed and such receiver or trustee, as the case may be, shall not
be discharged within 30 days after such appointment, then in any such case,
Landlord may, upon notice to Tenant, recover possession of and re-enter the
Premises without affecting Tenant's liability for past rent and other charges
due or future rent and other charges to accrue hereunder.  In the event of any
such default, Landlord shall be entitled to recover from Tenant, in addition to
rent and other charges equivalent to rent, all other damages sustained by
Landlord on account of the breach of this Lease, including, but not limited to,
the costs, expenses and reasonable attorneys' fees incurred by Landlord in
enforcing the terms and provisions hereof and in re-entering and recovering
possession of the Premises and for the cost of repairs, alterations and
brokerage and reasonable attorneys' fees connected with the reletting of the
Premises.  Further, at the election of Landlord, Landlord shall have the right
to declare this Lease terminated and canceled, without any further rights or
obligations on the part of Landlord or Tenant (other than Tenant's obligation
for rent and other charges due and owing through the date of termination), so
that Landlord may relet the Premises without any right on the part of Tenant to
any credit or payment resulting from any reletting of the Premises.  In case of
a default under this Lease, Landlord may, in addition to terminating this Lease,
or in lieu thereof, pursue such other remedy or combination of remedies and
recover such other damages for breach of tenancy and/or contract as are
available at law or otherwise.

     After any requisite written notice and the expiration of the applicable
cure period, Landlord may, but shall not be obligated to, cure any default by
Tenant

                                       15
<PAGE>

(specifically including, but not by way of limitation, Tenant's failure to
obtain insurance, make repairs, or satisfy lien claims) and whenever Landlord so
elects, all costs and expenses paid by Landlord in curing such default,
including without limitation reasonable attorneys' fees, shall be payable to
Landlord as additional rent due on demand, together with interest at the rate
provided in Paragraph 26 below from the date of the advance to the date of
repayment by Tenant to Landlord.

     A waiver by Landlord or Tenant of a breach or default by Tenant or Landlord
under the terms and conditions of this Lease shall not be construed to be a
waiver of any subsequent breach or default nor of any other term or condition of
this Lease, and the failure of Landlord or Tenant to assert any breach or to
declare a default by Tenant or Landlord shall not be construed to constitute a
waiver thereof so long as such breach or default continues unremedied.

     No receipt of money by Landlord from Tenant after the expiration or
termination of this Lease or after the service of any notice or after the
commencement of any suit, or after final judgment for possession of the Premises
shall reinstate, continue or extend the Term of this Lease or affect any such
notice, demand or suit.

25.  COSTS AND ATTORNEYS' FEES.  If Landlord or Tenant shall fail to abide by or
comply with the terms of this Lease, such party shall pay all costs, expenses
and reasonable attorney fees that may be incurred or paid by the other party in
enforcing the covenants and agreements of this Lease against it.  In the event
that any dispute between Landlord and Tenant arising under this Lease proceeds
to litigation, then the nonprevailing party in such litigation shall pay the
reasonable costs and attorneys fees of the prevailing party in such litigation.

26.  INTEREST.  Any amount due from Tenant to Landlord hereunder which is not
paid within five days after its due date shall bear interest at an annual rate
equal to the  lesser of (a) 3% per annum in excess of the reference rate of
interest announced, from time to time, by the Firstar Bank Milwaukee, N.A. or
its successor or (b) 12% per annum (but in no event shall such rate of interest
exceed the maximum rate of interest permitted to be charged by law) from the
date due until paid, compounded monthly, but the payment of such interest shall
not excuse or cure any default by Tenant under this Lease.

27.  SURRENDER.  Upon the termination of this Lease, by expiration or otherwise,
Tenant shall peaceably surrender the Premises to Landlord in good condition and
repair consistent with Tenant's duty to make repairs as provided herein.  All
Alterations and decorations made to the Premises by Tenant after the initial
build-out shall remain and be the property of Landlord unless Landlord shall
require Tenant (which election shall be made by Landlord at the time of
Landlord's consent to same), at Tenant's expense, to remove any or all thereof
and repair the damage caused by such removal.  All furniture, equipment and
unattached movable personal property owned by Tenant may (and upon Landlord's
request shall) be removed from the Premises by Tenant no later than the
termination date, and Tenant shall repair any and all damage caused by such
removal.  Tenant shall also remove its satellite dish from the roof of the
Building, its card access security system hardware and all cabling, wiring and
ancillary equipment installed by Tenant in the Premises or the Building and
repair any damage caused by such removal.  If the Premises are not surrendered
upon the termination of this Lease as set forth herein, Tenant shall indemnify
Landlord against all loss or liability resulting from delay by Tenant in so
surrendering the Premises including, without

                                       16
<PAGE>

limitation, any claim made by any succeeding tenant founded on such delay.
Tenant shall also surrender all keys to the Premises and shall inform Landlord
of combinations in any locks, safes and vaults, if any, in the Premises.

28.  HOLDOVER.  In the event Tenant remains in possession of the Premises after
the expiration of this Lease with the written consent of Landlord and without
the execution of a new lease, it shall be deemed to be occupying said premises
as a tenant from month-to-month, subject to all of the conditions, provisions
and obligations of this Lease insofar as the same are applicable to a month-to-
month tenancy.  Such month-to-month tenancy may be terminated by either party
effective as of the end of any calendar month 28 days' prior written notice to
the other party.  If Tenant remains in possession of the Premises without the
written consent of Landlord or remains in possession of the Premises following
the termination of a hold-over month-to-month tenancy as created pursuant to the
provisions of the preceding sentences, then Tenant shall pay to Landlord the
damages suffered by Landlord because of the failure of Tenant to vacate the
Premises as aforesaid and, in the absence of proof of greater damages, Landlord
may recover as minimum damages from Tenant twice the base rent apportioned on a
daily basis for the time Tenant remains in such possession.  This provision
shall not be deemed to waive Landlord's right of reentry or any other right
hereunder or at law.

29.  TRANSFER BY LANDLORD.  In the event of a bona fide sale or conveyance by
Landlord of the Building and its associated parking, the same shall operate to
release Landlord from any future liability upon any of the covenants or
conditions herein contained, and in such event Tenant agrees to look solely to
the successor in interest of Landlord in and to this Lease.  This Lease shall
not be affected by any such sale or conveyance, and Tenant agrees to attorn to
the purchaser or grantee, which shall be obligated on this Lease only so long as
it is the owner of Landlord's interest in and to this Lease.

30.  SUBORDINATION.  This Lease is and shall be subject and subordinate at all
times to all ground or underlying leases which now exist or may hereafter be
executed affecting the Building and to the lien of any mortgages now or
hereafter placed on or against the Building, or on or against Landlord's
interest or estate therein, and including all extensions, renewals, amendments
and supplements to any such lease or mortgage, provided that any subordination
to a ground or underlying lease or a mortgage entered into or granted subsequent
to the Commencement Date shall be conditioned upon such lessors or holders
recognizing the rights of Tenant under this Lease so long as Tenant is not in
default beyond any applicable cure period.  Tenant covenants and agrees to
execute and deliver upon demand such further reasonable instruments evidencing
such subordination of this Lease to such ground or underlying leases and to the
lien of any such mortgages as may be required by Landlord provided that any
lessor under any such ground or underlying lease or the holder of any mortgage
has agreed to recognize the rights of Tenant under this Lease so long as Tenant
is not in default hereunder beyond any applicable cure period.  Notwithstanding
anything herein above contained in this section, in the event the holder of any
mortgage or the lessor under any ground or underlying lease shall at any time
elect to have this Lease constitute a prior and superior lien to its mortgage or
lease, then and in such event, upon any such holder notifying Tenant to that
effect in writing, this Lease shall be deemed prior and superior in lien to such
mortgage or lease, whether this Lease is dated prior to or subsequent to the
date of such mortgage or lease.

                                       17
<PAGE>

31.  Intentionally Left Blank.

32.  ESTOPPEL CERTIFICATES.  Tenant agrees that at any time and from time to
time upon not less than ten days' prior request of Landlord, Tenant shall
execute, acknowledge and deliver to Landlord a statement in writing certifying
(a) that this Lease is unmodified and in full force and effect (or if there have
been modifications, specifying the same), and (b) the dates to which the rent
and other charges have been paid, and (c) that, so far as Tenant knows, Landlord
is not in default under any provisions of this Lease (or if Tenant knows of any
such default, specifying the same), and (d) such other matters as Landlord or
Landlord's mortgagee may reasonably require.  It is intended that any such
statement may be relied upon by any person proposing to acquire Landlord's
interest in this Lease or any prospective mortgagee of, or assignee of any
mortgage upon, such interest.  Upon Tenant's request, Landlord shall provide a
similar estoppel certificate.

33.  SORTING AND SEPARATION OF REFUSE AND TRASH.  Tenant agrees, at its sole
cost and expense, to comply with all present and future laws, orders, and
regulations of all state, federal, municipal, and local governments,
departments, commissions and boards regarding the collection, sorting,
separation and recycling of waste products, garbage, refuse and trash into such

products, garbage, refuse and trash shall be placed in separate receptacles
specified by Landlord.  Such separate receptacles may, at Landlord's option, be
removed from the Premises in accordance with a collection schedule prescribed by
law.  Landlord reserves the right to refuse to collect or accept from Tenant any
waste products, garbage, refuse or trash that is not separated and sorted as
required by law or in accordance with the provisions of this paragraph, and to
require Tenant to arrange for such collection at Tenant's sole cost and expense,
utilizing a contractor satisfactory to Landlord.  Tenant shall pay all costs,
expenses, fines, penalties or damages that may be imposed on Landlord or Tenant
by reason of Tenant's failure to comply with the provisions of this paragraph,
and, at Tenant's sole cost and expense, shall indemnify, defend, and hold
Landlord harmless (including attorneys' fees and expenses) from and against any
actions, claims, and suits arising from such noncompliance, utilizing counsel
reasonably satisfactory to Landlord.

35.  EXECUTION.  The submission of this document for examination does not
constitute an offer to lease, or a reservation of, or option for, the Premises
and this document becomes effective and binding only upon the execution and
delivery hereof by both Landlord and Tenant.  Tenant confirms that Landlord has
made no representations or promises with respect to the Premises or the making
or entry into of this Lease except as are expressly set forth herein, and agrees

41.  EXPANSION OPTIONS.  Provided that Tenant is not in default at the time
Tenant delivers the written notices required by this section, Tenant shall have
the following options to expand the Premises, which any one or all may be
exercised by the Tenant:

     A.  Adjacent Space.  Tenant shall have the option to lease in its entirety
the approximately 45,000 rentable square foot premises located adjacent to the
Premises described on attached Exhibit F (the "Adjacent Space").  If Tenant
elects to so lease the Adjacent Space, Tenant shall provide written notice to
Landlord of such election on or before November 30, 2000 and shall specify in
such notice the

                                       19
<PAGE>

tenant improvements for the Adjacent Space desired by Tenant. Subject to the
limits of the tenant improvement allowance provided for herein, the Landlord
shall deliver the Premises in the condition requested by Tenant between July 1,
and September 30, 2001. The Base Component of the Base Rent applicable to the
Adjacent Space shall be equal on a per rentable square foot basis to the Base
Component of the Base Rent then in effect for the original Premises. If, prior
to delivery of Tenant's election notice, the Adjacent Space is improved in a
manner consistent with Tenant's requirements, then the annual Base Rent for the
Adjacent Space shall include a Tenant Improvement Component equal to (i) the
unamortized cost of such tenant improvements over the remaining term of the
Lease at an annual interest rate of 10%, plus (ii) the cost of any additional
tenant improvements requested by Tenant, amortized over the remaining term of
the Lease at an annual interest rate of 10%. Such Tenant Improvement Component
of the Base Rent for the Adjacent Space shall be payable in the same manner as
the Tenant Improvement Component of the Base Rent for the initial Premises.
Further, the principal amount to be amortized under (i) and (ii), above, shall
not exceed $16 per rentable square foot of the Adjacent Space. If, prior to
delivery of Tenant's election notice, the Adjacent Space has not been improved
beyond its present condition, then Tenant shall be granted a tenant improvement
allowance of up to $16.00 per rentable square foot of the Adjacent Space and
Landlord shall improve the Adjacent Space to Tenant's specifications set forth
in Tenant's election notice (up to the maximum amount of the tenant improvement
allowance). In such case, the annual Base Rent for the Adjacent Space shall
include a Tenant Improvement Component equal to the actual amount of the tenant
improvement allowance expended amortized over the remaining term of the Lease at
an annual interest rate of 10%, payable in the same manner as the Tenant
Improvement Component of the Base Rent for the initial Premises. Upon delivery
of the Adjacent Space to Tenant (with the applicable build out completed), the
terms of this Lease shall be made applicable to the Adjacent Space and Tenant's
obligation to pay rent for the Adjacent Space shall commence.

          If (i) Landlord has leased the Adjacent Space to an interim tenant
prior to April 1, 2000, or (ii) Landlord has not leased the Adjacent Space to an
interim tenant prior to April 1, 2000 but Tenant exercises its option to lease
the Adjacent Space on or before July 31, 2000, then the option granted to Tenant
for the Adjacent Space shall be provided to Tenant for no additional
consideration. If neither of the two preceding conditions are met, then Tenant
shall retain the right to exercise the option for the Adjacent Space from August
1, 2000 through December 31, 2000, only if Tenant pays to Landlord on or before
July 31, 2000 the amount of $135,000. If Tenant fails to make such payment by
such date, Tenant's option for the Adjacent Space shall terminate. If Tenant
makes such payment and thereafter timely exercises such option, the amount of
such payment shall be credited against the first rental payments due for the
Adjacent Space.

     B.  Mezzanine Space.  Tenant shall also have the option to lease the
approximately 15,200 rentable square foot premises located in the Mezzanine
described on attached Exhibit F (the "Mezzanine Space").  If Tenant elects to so
lease the Mezzanine Space, the Tenant shall provide written notice to Landlord
of such election on or before June 30, 2000, provided, however, that if Landlord
has secured an interim tenant for the Adjacent Space on or before April 1, 2000,
then tenant shall have until November 30, 2000 to exercise its option for the
Mezzanine Space.  Such election notice shall specify the tenant improvements for
the Adjacent Space desired by Tenant.  Subject to the limits of the tenant
improvement allowance provided for herein, Landlord shall deliver the Mezzanine
Space to Tenant in the condition requested by Tenant within seventy five days
after delivery

                                       20
<PAGE>

of Tenant's notice. The Base Rent for the Mezzanine Space shall be calculated in
the same manner as the Base Rent for the Adjacent Space (i.e., the Base
Component to be equal to the Base Component then in effect for the original
Premises and the Tenant Improvement Component to be equal to the remaining
unamortized cost of improvements made prior to Tenant's election notice, if any,
plus the amortized cost of the tenant improvements requested by Tenant to the
extent of a $16 per rentable square foot tenant improvement allowance), as
described above. Upon delivery of the Mezzanine Space to Tenant (with the
applicable build out completed), the terms of this Lease shall be made
applicable to the Mezzanine Space and Tenant's obligation to pay rent for the
Mezzanine Space shall commence.

     C.  Northwest Corner Space.  Tenant shall also have the option to lease the
approximately 25,000 rentable square foot premises located in the northwest
corner described on attached Exhibit F (the "Northwest Corner Space") formerly
known as Gareth Stevens, Pro Tel Marketing and Journal Sentinel space.  If
Tenant elects to so lease the Northwest Corner Space, the Tenant shall provide
written notice to Landlord of such election on or before November 30, 2000 and
shall specify in such notice the tenant improvements for the Northwest Corner
Space requested by Tenant.  Subject to the limits of the tenant improvement
allowance provided herein, the Landlord shall deliver the Northwest Corner Space
to Tenant in the condition requested by Tenant within seventy five days after
delivery of Tenant's notice.  Landlord shall grant Tenant a tenant improvement
allowance of up to $16 per rentable square foot of the Northwest Corner Space.
The Base Rent for the Northwest Corner Space shall be calculated in the same
manner as the Base Rent for the Adjacent Space (i.e., the Base Component to be
equal to the Base Component then in effect for the initial Premises and the
Tenant Improvement Component to be equal to the amortized cost of the actual
amount of the tenant improvement allowance expended), as described above.  Upon
delivery of the Northwest Corner Space to Tenant (with the applicable buildout
completed), the terms of this Lease shall be made applicable to the Northwest
Corner Space and Tenant's obligation to pay rent for the Northwest Corner Space
shall commence.

     D.  Tenant's Proportionate Share; Parking.  At such times as Tenant
exercises any of the foregoing options, Tenant's Proportionate Share shall be
readjusted to reflect the percentage of the Building occupied by Tenant.
Further, Landlord shall provide Tenant with additional unreserved parking spaces
sufficient to accommodate the additional number of employees occupying the
Premises subsequent to such expansion.

42.  OPTIONS TO EXTEND.  Provided that Tenant is not then in default either at
the time Tenant delivers the written notice required by this section or at the
time of commencement of an extension term, Tenant shall have the option to
extend the term of this Lease for up to fifteen years in three separate and
additional terms of five years each (provided that Tenant may, if it chooses,
combine the first two extension options and extend the term of the Lease for ten
years upon delivery of the requisite notice) under the same terms and conditions
as set forth in this Lease except that the Base Rent shall be adjusted as
hereafter provided.  Tenant shall exercise any of its options to extend this
Lease by delivering written notice of such exercise to Landlord at least one
year prior to the expiration of the original or extended term of the Lease, as
the case may be.  The Base Rent for the first year of each extension term shall
be 95% of the Fair Market Rental (as hereafter determined); provided, however,
that in no event shall the Base Rent for the Premises for the first year of each
extension term be less than 100% of the average

                                       21
<PAGE>

per rentable square foot of the Base Component of the Base Rent for the entire
Premises during the immediately preceding year nor more than 102.5% of the
average per rentable square foot of the Base Component of the Base Rent for the
entire Premises during the immediately preceding year. Thereafter, the Base Rent
for the Premises for each year of the extension term shall increase by 2 1/2%
per year. For each five year extension exercised by Tenant, Tenant shall receive
a Tenant improvement allowance of $2.00 per rentable square foot of the
Premises, which allowance shall be credited against the monthly rental payments
next due and payable by Tenant under the Lease until the full amount has been
credited to Tenant. If Tenant elects to exercise its first option to extend the
Lease for a period of ten years rather than five years, then the tenant
improvement allowance to Tenant shall be $4.00 per rentable square foot rather
that $2.00 per rentable square foot.

     For purposes of this section, Fair Market Rental shall mean the base rent
for comparable space in the Project's market area.  The determination of Fair
Market Rental shall take into account the tenant improvement allowance offered
to Tenant and all other relevant factors.  If Landlord and Tenant are unable to
agree on the Fair Market Rental within thirty days after Tenant's exercise of
each of the options to extend, then the Fair Market Rental shall be determined
by appraisal.  Landlord and Tenant shall each designate by written notice within
ten days after the expiration of said thirty day period, the name of a qualified
appraiser who shall have at least five years experience relative to office space
in said market area.  Each of the appraisers shall submit to Landlord and Tenant
within thirty days after his or her appointment, a written determination of the
Fair Market Rental for the applicable option period.  If both of the appraisers'
determinations are within the minimum and maximum Base Rent amounts previously
set forth in this section, then the Fair Market Rental shall be the average of
the two appraisals.  If only one of the appraiser's determinations is within
such minimum and maximum Base Rent amounts, then the Fair Market Rental shall be
equal to such determination.  If neither appraiser's determinations is within
the minimum and maximum Base Rent amounts, then the Fair Market Rental shall be
the average of such minimum and maximum Base Rent amounts.

43.  EXCLUSIVE USE.  Notwithstanding any provision to the contrary, Landlord
covenants that Landlord will not lease to or allow any space in the Building not
leased by Tenant to be leased to or used by any person or entity whose principal
use of such space in the Building would be providing data services to financial
institutions.  Landlord acknowledges that money damages in the event of default
by Landlord are inadequate and accordingly Tenant shall have the right, in
addition to any other remedy available, to apply for and receive from a court of
competent jurisdiction equitable relief by way of restraining order, injunction,
specific performance or otherwise to prevent a breach or to enforce the terms
hereof.  Landlord further acknowledges that said covenant and agreement of
Landlord herein is material inducement for Tenant to enter into this Lease.

44.  ADDENDA.  The provisions, if any, included at the end of this Lease, and
any riders and exhibits appended to this Lease, are hereby made a part of this
Lease as though set forth in full at this point Base Rent amounts.

     EXECUTED as of the date first written above.

     A.  Landlord and Tenant entered into an Office Lease dated as of March 9,
2000 (the "Lease") for approximately 50,547 square feet of space in a building
known as the 1515 RiverCenter Drive Building in the Schlitz Park Complex in

foregoing shall remain in full force and effect.
