         (q) Ground Lease: That certain Ground Lease (for a term of fifty (50)
years with two (2) twenty (20) year options to renew) dated November 16, 1999,
which is styled "University Research Park Ground Lease" by and between
University Research Park, Incorporated, a Wisconsin nonprofit corporation, as
Landlord and Rosa Point, LLC, a Wisconsin Limited Liability Company, as Tenant,
for the lease of the Property. Tenant hereby acknowledges that this Lease is
subject to the Ground Lease and that has received a copy of the Ground Lease
prior to the execution of this Lease. Landlord agrees to comply with all terms

                                    ARTICLE 1
                                    BASE RENT

         1.01 Rent Reserved and Monthly Payments. In consideration of the
leasing of the Premises, Tenant agrees to pay to Landlord without setoff,
deduction or demand, at the address set forth in the Data Sheet, or at such
other place as Landlord from time to time may designate in writing, the Base
Rent as provided in this Section 1.01. The Annual Base Rent shall be determined
by multiplying the number of square feet in the Premises by the annual Base Rent
per square foot set forth in the Data Sheet. The Monthly Base Rent shall be
determined by dividing the Annual Base Rent by twelve (12). Tenant shall pay
Landlord the Monthly Base Rent in advance on the first day of each and every
month during the Term commencing on the Commencement Date. If the Term commences
on a date other than the first day of a calendar month, Monthly Base Rent for
such partial month, as the case may be, shall be obtained by multiplying the
number of days in the Term within such month by a fraction, the numerator of
which is the Monthly Base Rent and the denominator of which is the number of
days in such month.

                                   ARTICLE II
                                 ADDITIONAL RENT

         2.01 Additional Rent. In addition to the Base Rent payable by Tenant
under the provisions of Article I hereof, Tenant shall pay to Landlord,
commencing on the Commencement Date and on the first day of each and every month
of the Term, "Additional Rent" as hereinafter provided. The term "Additional
Rent" shall mean and include Tenant's Share of Operating Expenses (as defined in
Section 2.02 (A)(i)), Tenant's Share of Taxes (as defined in Section 2.02
(A)(ii)), Tenant's Share of Utilities (as defined in Section 2.02 (A)(iii)), and
Tenant's Share of Service Charges (as defined in Section 2.02 (F)). Subject to
reimbursement hereunder, Landlord shall pay Operating Expenses, Taxes, Utilities
and Service Charges before they become delinquent.

becomes delinquent.

         2.02 Definitions. For purposes of this Article II, the parties hereto
agree upon the following definitions:

                  A. The Tenant's Share of Operating Expenses, Tenant's Share of
Taxes, and Tenant's Share of Utilities, shall be determined each Lease Year as
follows:

                           (i) Tenant's Share of Operating Expenses shall be
determined by multiplying both Operating Expenses (as defined in Section 2.02
(B) hereof) by the percentage that the square footage of the Premises is of the
total rentable square footage in the Building.

                           (ii) Tenant's Share of Taxes shall be determined by
multiplying Taxes (as defined in Section 2.02 (C) hereof) by the percentage that
the square footage of the Premises is of total rentable square footage of the
Building.

                           (iii) Tenant's Share of Utilities shall be determined
by multiplying utilities (as defined in Section 2.02(E) hereof) by the
percentage that the square footage of the Premises is of the total leased
rentable square footage of the Building.

                           (Iv) The square footage of common areas of the
Building shall not be taken into account when determining Tenant's Share of
Operating Expenses, Tenant's Share of Taxes, and Tenant's Share of Utilities, as
provided in Subsections (i), (ii), and (iii) of this Subsection (A), it being
the intention of the parties that all of such expenses be allocated to rentable
space in the Building.

                           (v) Should any of the percentages in Subsections (i),
(ii), and (iii) of this Subsection (A) change during a Lease Year, it shall be

administration, and maintenance of an office complex and not specifically set
forth herein; and assessments attributable to the Facility on account of costs
incurred by any business park association for the business park in which the
Facility is located. Operating Expenses shall be reduced by reimbursements,
credits, discounts, reductions, refunds or other allowances received by Landlord
for items of cost included in an Operating Expense, excluding reimbursements to
Landlord by Tenant under this Lease or by any other tenant under any other
lease(s) which affect the Facility.

                           (2) Except as provided in Subsection (3) of the
Subsection (B), the term "Operating Expenses" shall not include any capital

any lease or of any law, statute, ordinance, or of any insurance rating bureau
or other quasi-public authority, or of any debt agreement or the Ground Lease;

(5%) of rent and Operating Expenses (exclusive of such management fees) and all

which would be paid absent such relationship; any cost for any facility other

the Term of this Lease and are not incurred to correct defects in the original
construction of the Building, Landlord may include in Operating Expenses

payable by Tenant under this Lease other than Base Rent, Tenant's Share of

Landlord reserves the right to contract for services which will be consumed
within the Premises separately with those providing such services. To the extent
Landlord contracts separately for services to be consumed within the Premises,
Tenant shall be billed for such services as a Service Charge.

         2.03 Additional Rent Estimates. Landlord shall estimate for each such
Lease Year (i) the total amount of Operating Expenses; (ii) the total amount of
Taxes; (iii) the total amount of Utilities; (iv) the total amount of Service
Charges Payable by the Tenant. Said estimate shall be in writing and Landlord
shall use reasonable efforts to deliver or mail same to Tenant at the Premises
within ninety (90) days of the close of each Lease Year. Landlord may adjust
such estimates from time to time during the Lease Year.

         2.04 Payment of Additional Rent Estimates. Tenant shall pay the
Additional Rent so estimated, in equal monthly installments, in advance, on the
first day of each month during each applicable Lease Year. In the event that
said estimate is delivered to Tenant after the first day of January of the
applicable Lease Year, said amount, so estimated, shall be payable as Additional
Rent, in equal monthly installments, in advance, on the first day of each month
over the balance of such Lease Year, with the number of installments being equal

         2.05 Annual Determination of Additional Rent. Upon completion of each
Lease Year, Landlord shall determine the actual amount of Operating Expenses,
Taxes, Utilities and Service Charges for such Lease Year and Tenant's Share
thereof and deliver a written, itemized certification of the amounts thereof to
Tenant not later than 120 days after the end of such Lease Year. If Tenant has
paid less than Tenant's Share of Operating Expenses, Tenant's Share of Taxes,
Tenant's Share of Utilities, and Service Charges payable by Tenant for any Lease
Year, Tenant shall pay the balance of the same within thirty (30) days after the
receipt of such statement. If Tenant has paid more than Tenant's Share of
Operating Expenses, Tenant's Share of Taxes, Tenant's Share of Utilities, and
Service Charges for any Lease Year, Landlord shall credit such excess against
the most current monthly installment or installments due Landlord for Additional
Rent estimates. A pro rata adjustment shall be made for a fractional Lease Year
occurring during the Term of this Lease or any renewal or extension thereof
based upon the number of days of the Term of this Lease during said Lease Year
as compared to three hundred sixty-five (365) days and all additional sums
payable by Tenant or credits due Tenant as a result of the provisions of this
Article II shall be adjusted accordingly. Landlord shall provide Tenant with
supporting calculations for determining the Additional Rent and copies of
documentation supporting

                                      -8-
<PAGE>   9

Landlord's calculations of Additional Rent upon request by Tenant. Landlord
reserves the right to charge Tenant for the cost of copying documents which
Landlord provides to Tenant under this Section. If, after an audit by Tenant of
Additional Rent documentation for any Lease Year, it is determined that Tenant
was overcharged or undercharged for Additional Rent in any Lease Year (i) any
overcharge shall be credited against the amount Tenant owes for Landlord for
current or future Additional Rent or if this Lease has terminated, such
overcharge shall be credited by Landlord against any payments Tenant then owes
Landlord unless Tenant does not then owe Landlord any payments or the amount of
the overcharge exceeds the amount of the payments Tenant owes Landlord, in which
case Landlord shall immediately refund the net amount of the overcharge to
Tenant, and (ii) any undercharge shall immediately be paid by Tenant to
Landlord. If, after an audit by tenant of Additional Rent documentation for any
Lease Year, Tenant 's Additional Rent for such Lease Year is adjusted in
Tenant's favor by more than five percent (5%) of the Additional Rent paid by
Tenant during such Lease Year due to an error committed by Landlord or
Landlord's agent, Landlord shall pay to Tenant the amount reasonably incurred by
Tenant to conduct such audit or review of the Additional Rent documentation for
such Lease Year. Notwithstanding the foregoing, no adjustment to Additional Rent
payable by Tenant hereunder for any overcharge or undercharge in the amount of
Additional Rent paid by Tenant in any Lease Year disclosed by an audit of
Additional Rent Documentation shall be made unless notice of the amount of the
overcharge or undercharge is given by Landlord or Tenant to the other within One
(1) year after the end of such Lease Year; provided however, such time
limitation shall not apply to a continuing error for up to Two (2) Lease Years
prior to the Lease Year in which the error was discovered.

         2.06 Rental Taxes. Further, Tenant shall pay, also as Additional Rent,
any tax or excise on Rents, gross receipts tax, or other tax, however described,
which is levied or assessed by the United States of America or the state in
which the Facility is located or any political subdivision thereof, against
Landlord in respect to the Rent or other charges reserved under this Lease or as
a result of Landlord's receipt of such Rents or other charges accruing under
this Lease, all of which shall herein be termed "Rental Taxes"; provided,
however, Tenant shall have no obligation to pay net income taxes of Landlord.

         2.07 Tenant's Taxes. Tenant shall pay, prior to delinquency, all taxes
assessed or levied upon its occupancy of the Premises, or upon the trade
fixtures, furnishings, equipment and all other personal property of Tenant
located in the Premises, and when possible, Tenant shall cause such trade
fixtures, furnishing, equipment and other personal property to be assessed and
filed separately from the property of Landlord. In the event any or all of
Tenant's trade fixtures, furnishings, equipment or other personal property, or
Tenant's occupancy of the Premises, shall be assessed and taxed with the
property of Landlord, Tenant shall pay to Landlord its share of such Taxes
within twenty (20) days after delivery to Tenant by Landlord of a

                                      -9-
<PAGE>   10

statement in writing setting forth the amount of such Taxes applicable to
Tenant's personal property. Landlord shall provide supporting documentation for
such Taxes upon request by Tenant.

                                   ARTICLE III
                        OVERDUE AMOUNTS; RENT INDEPENDENT

         3.01 Payment of Rent. Any Rent or any other charges to be paid by

(10) days after becoming due, shall bear interest at the rate of two (2) points
over the quoted prime rate of interest quoted in the Wall Street Journal per
annum from the date when the same is due until the same shall be paid, but if

under the laws of the State of Wisconsin.

         4.02 Tenant Improvements. Landlord represents and warrants that the
Premises currently conforms with the Base Building Requirements referred to in
Exhibit B hereof. Landlord shall complete the common areas of the Building in
conformance with Exhibit B hereof. Landlord and Tenant acknowledge that Landlord
on behalf of Tenant, at Landlord's sole expense, will be improving the Premises
prior to Tenant's occupancy of it as provided in the Work Letter at Exhibit E
hereof (the "Initial Tenant Improvements"); provided, however, Tenant shall pay,
prior to its occupying the Premises, the cost of all Work beyond that called for
in the plans and specifications attached to Exhibit E, which is occasioned by
the change orders requested by Tenant in writing. Tenant shall pay for the extra
tenant improvements shown as Extras 1 through 4 on Exhibit F attached hereto.
All Initial Tenant Improvements shall comply with the provisions of Article VIII
hereof. Tenant shall have access to the Premises upon the execution of this
Lease for the purposes of constructing any additional Tenant improvements and
not less than 30 days prior to completion of Landlord-constructed Tenant
Improvements for installation of data and communications equipment, cabling, and
security system, and furniture. Landlord will use its best efforts to complete
the Tenant Improvements to be constructed by Landlord as shown on Exhibit E
hereof not later than April 30, 2001. In the event such deadline is missed, the
Commencement Date of this Lease, the dates for payment of Rent under this Lease,
and the Term of this Lease shall be extended on a day-for-day basis through the
date of completion. Notwithstanding anything in this Lease to the contrary,
Tenant shall not make any structural changes to the Building. For example,
Tenant shall not make any holes in any concrete floors or exterior walls or the
roof of the building or interfere in any way with any supporting beams in the
Building. LANDLORD MAKES NO WARRANTIES, EXPRESS OR IMPLIED, INCLUDING BUT NOT
LIMITED TO IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A SPECIFIC
PURPOSE IN CONNECTION WITH THE INITIAL TENANT IMPROVEMENTS. Landlord hereby
assigns all warranties, if any, supplied by the contractor(s) which construct
the Initial Tenant Improvements to Tenant until the end of the Term whereupon

and Landlord covenants and agrees to cooperate with Tenant during the Term in
the enforcement in such warranties.

         4.03 Commencement Date. Tenant shall have and hold the Premises,
without any liability or obligation on the part of Landlord to make any
alterations, improvements or repairs of any kind in or about the Premises,
except as expressly provided herein, for the Term set forth on the Data Sheet
unless sooner terminated in the manner provided herein. Subject to Section 4.02
above, the Term shall commence on the Commencement Date as set forth in the Data
Sheet. If Landlord shall be unable to give possession of the Premises on the
Commencement Date because the

                                      -11-
<PAGE>   12

construction of the common areas of Facility have not been sufficiently
completed to make the Premises ready for occupancy, or for any other reason,
Landlord shall not be subject to any claims, damages or liabilities for the
failure to give possession on said date. Under said circumstances, the
Commencement Date shall be the date the Premises are ready for occupancy. The
failure of Landlord to give possession of the Premises to Tenant and complete
Landlord's Tenant Improvements as described in Section 4.02 above by the
Commencement Date shall in no way affect the validity of this Lease or the
obligations of Tenant hereunder unless not completed by June 1, 2001, in which
case Tenant shall have the right to terminate this Lease. If Tenant is given and
accepts possession of the Premises on a date earlier than the Commencement Date
specified, the Rent reserved herein and all covenants, agreements and
obligations herein and the Term of this Lease shall commence on the date that
possession of the Premises is given to Tenant. Tenant may have access to the
Premises upon the execution of this Lease for the purpose of installing Tenant's
Tenant Improvements, fixtures and furniture and other items supplied by Tenant
and no rent shall be payable during such time.

         4.04 Acceptance of Premises. The acceptance of possession by Tenant
shall be deemed to conclusively establish that the Premises and all other
improvements of the Facility required to be constructed by Landlord for use
thereof by Tenant hereunder have been completed unless Tenant notifies Landlord
in writing within thirty (30) days after the Commencement Date as to any items
not completed or which are defective. Tenant shall have access to the Premises

         4.05 Confirmation of Commencement Date and Term. Within thirty (30)
days after the Commencement Date, the Landlord and Tenant shall confirm the
Commencement Date and the date the Initial Term expires in writing.

this Lease, Tenant shall have the right and option to extend the Initial Term of
this Lease for three (3) successive periods of three (3) years each (the
"Extended Terms"), the Extended Terms to commence immediately upon the
expiration of the Initial Term. Such option shall be exercised by delivery of
written notice by Tenant to Landlord not less than one hundred twenty (120) days
and no more than two hundred forty (240) days prior to the expiration of the
Initial Term and, if applicable, the first and second Extended Terms. During the

Annual Ground Lease Rent

                                      -12-
<PAGE>   13

in effect at the execution of this Lease by (ii) the percentage that the square
footage of the Premises is of total rentable square footage of the Building; and

         B. during the first year of the second and third Extended Terms, Annual
Base Rent shall increase by three percent (3%) over the Annual Base Rent in
effect during the immediately previous year plus the product derived from

Section 2.02(D) hereof) in effect at the beginning of each such Extended Term
has increased over the Annual Ground Lease Rent in effect at the beginning of
the immediately preceding Extended Term by (ii) the percentage that the square
footage of the Premises is of total rentable square footage of the Building; and

         C. during the second and third years of each of Extended Terms, Annual
Base Rent shall increase by three percent (3%) over the Annual Base Rent in

         D. there shall be no option to extend this Lease beyond the third
Extended Term.

all Utilities and other services consumed during hours which exceed Tenant's
normal hours as set forth in Exhibit D. The security system Landlord will
provide for the Building is described in Exhibit B of this Lease. If Tenant
desires further security services, such services shall be procured by Tenant at
Tenant's sole expense.

         5.02 Interruption of Services. No interruption in, or temporary
stoppage of, any of the aforesaid services caused by repairs, renewals,
improvements, alterations, strikes, lockouts, labor controversy, accidents,
inability to obtain fuel or supplies or other causes shall be deemed an eviction
or disturbance of Tenant's use and possession, or render Landlord liable for
damages, by abatement of Rent or otherwise or relieve Tenant from any obligation
herein set forth, unless caused by Landlord's negligent or intentional act or
omission. In no event shall Landlord be required to provide any heat, air
conditioning, electricity or other service in excess of that permitted by
involuntary guidelines or laws, ordinances or regulations of governmental
authority.

         5.03 Adjustment to Operating Expenses. Anything in this Lease to the
contrary notwithstanding, Landlord shall have the right to specially assess
Tenant a Service Charge for additional services or other items of Operating
Expenses (and shall reduce the total of Operating Expenses accordingly) to the
extent Tenant's use or consumption thereof due to hours of operation, equipment
operated from the Premises, or other reasons, reasonably warrant such
assessment. Upon written request by Tenant, Landlord shall provide backup
information to support such assessment.

                                   ARTICLE VI
                                    INSURANCE

or may in the future be, customarily covered including, but not limited to,
windstorms, hail, explosions, vandalism, theft, malicious mischief, civil
commotion, and such other coverage deemed necessary by Landlord, providing such
additional coverage is such as is customarily carried with respect to buildings
and improvements similar in construction, general location, use, occupancy and
design to the Facility. Such casualty insurance may include provisions insuring
Landlord against loss of Rent. These insurance provisions shall in no way limit
or modify any of the obligations of Tenant under any provision of this Lease.

                  B. Landlord's Liability Insurance. Landlord shall, as a
portion of the Operating Expenses, maintain, for its benefit and the benefit of
its managing agent, general public liability insurance against claims for

sole cost and expense, maintain general public liability insurance against

Tenant agrees to defend and hold Landlord, its agents, employees and servants
harmless and indemnify them against claims and liability for injuries to or
arising out of such property, except to the extent such claims or liability

employees, servants and its managing agent.

                  E. Releases. Landlord and Tenant each agree that such policy
or policies of insurance for loss or damage by fire or other risks shall permit

waiving party's property or loss of use thereof

                                      -16-
<PAGE>   17

legally permitted in the Premises, Tenant shall pay the additional premium on
such insurance.

                  A. To control, install, affix and maintain any and all signs

not visible from outside the Premises.

                  B. To reasonably designate, limit, restrict and control any

sentence, Tenant need not obtain Landlords consent to Work in any single
instance where the projected cost of such Work is less than Ten Thousand Dollars

Landlord to inspect construction operations in connection with the Work. Tenant
shall not be allowed, without Landlord's reasonable approval, to perform such
Work if such action would materially interfere with Landlord's operation of the
Facility.

and replaced promptly by Tenant at its sole cost and expense to the reasonable
satisfaction of Landlord. All repairs, restorations and replacements shall be in
quality and class equal to the original work. Tenant shall do such periodic
painting, and cleaning of the Premises as may be reasonably required by

make any repairs, alterations or improvements that are the obligation of Tenant.
Landlord shall take reasonable precautions so as to minimize the unnecessary
interruption of Tenant's business.

                                    ARTICLE X

reasonably deems necessary. In making Landlord's determination as to whether to
consent to any proposed sublease or to any proposed assignment of this Lease, it
shall be reasonable for Landlord to take into consideration, without limitation
by enumeration, the following factors: (i) the business reputation and credit
worthiness of the proposed subtenant or assignee; (ii) the estimated increased
pedestrian and vehicular traffic on the Premises and to the Facility which would
be generated by the proposed subtenant or assignee; and (iii) the proposed use
to be made of the Premises. Notwithstanding the foregoing, Tenant may assign
this Lease without Landlord's prior written consent and without release of
Tenant from liability under this Lease to any entity controlling, controlled by,
under common control with Tenant or any entity that acquires Tenant or Tenant's
subsidiary that is the user of the Premises or substantially all of the assets
of Tenant or Tenant's subsidiary that is the user of the Premises (collectively,
a "Tenant Affiliate").

         10.02 Change in Tenant Status. If, at any time during the Term, Tenant
or its guarantor, if any, is (i) a corporation, entity or a trust (whether or
not having shares of beneficial interest) and there shall occur any change in
the identity of any of the persons then having a controlling power in the
election or appointment of the directors, trustees or other persons exercising
like functions and managing the affairs of Tenant; or, (ii) a partnership or
association or otherwise not a natural person (and is not a corporation or
trust) and there shall occur any change in the identity of either the managing
partner or the controlling interest of such partnership or association who
comprise Tenant; then

                                      -20-
<PAGE>   21

Tenant shall notify Landlord in writing and Landlord may declare this Lease no
longer in effect, by written notice to Tenant given within ninety (90) days
after the date of such notice by Tenant. This Section 10.02 shall not apply if,
at the execution of this Lease, Tenant or Tenant's guarantor, if any, named
herein is a corporation and the outstanding voting stock thereof is listed on a
recognized securities exchange.

         10.03 Continuing Liability. No subletting or assignment of this Lease
shall release or discharge Tenant of or from any liability, whether past,
present or future, under this Lease, and Tenant shall continue fully liable
thereunder unless Landlord shall agree otherwise in writing. The subtenant or
assignee shall agree in a form satisfactory to Landlord to comply with and be
bound by all of the terms, covenants, conditions, provisions and agreements of
this Lease to the extent of the space sublet or assigned, and Tenant shall
deliver to Landlord promptly after execution an executed copy of each such
subtenant or assignee. Consent by Landlord to any assignment of this Lease or to
any subletting of the Premises shall not be a waiver of Landlord's rights under
this Article as to any subsequent assignment or subletting.

         10.04 Payment to Landlord.

                  A. Landlord will not unreasonably withhold, condition or delay
its consent to Tenant's assignment of the Lease or subletting of such space and
incidental rights to the party identified in Tenant's notice, provided, however,
that in the event Landlord consents to any such assignment or subletting, and as
a condition thereto, Tenant shall pay to Landlord fifty percent (50%) of all net
profit derived by Tenant from such assignment or subletting other than to a
Tenant Affiliate. For purposes of the foregoing, profit shall be deemed to
include, but shall not be limited to, the amount of all Rent payable by such
assignee or sublessee in excess of all Rent payable by Tenant under this Lease,
net of all reasonable expenses incurred by Tenant in obtaining said assignee or
sublessee. If a part of the consideration for such assignment or subletting
shall be payable other than in cash, the payment to Landlord shall be in cash
for its share of any non-cash consideration based upon the fair market value
thereof.

                  B. Tenant shall and hereby agrees that it will furnish to
Landlord upon request from Landlord a complete statement setting forth in detail
the computation of all profit derived and to be derived from such assignment or
subletting, such computation to be made in accordance with generally accepted
accounting principles. The percentage of Tenant's profit due Landlord hereunder
shall be paid to Landlord within fifteen (15) days of receipt by Tenant of all
payments made from time to time by such assignee or sublessee to Tenant.

         10.05 Miscellaneous. Any sale, assignment, mortgage, transfer, or
subletting of this Lease which is not in compliance with the provisions of this
Article X shall be of no effect and void. Landlord's right to assign its
interest in this Lease shall remain unqualified.

                                   ARTICLE XI
                        DAMAGE BY FIRE OR OTHER CASUALTY

         11.01 Premises Destruction. If fire or other casualty shall render the
whole or any material portion of the Premises untenantable, then

                  A. If the Premises can reasonably be expected to be made
tenantable within one hundred eighty (180) days from the date of such event,
Landlord shall repair and restore the Premises and the Facility to as near their
condition prior to the fire or other casualty as is reasonably possible within
such one hundred eighty (180) day period (subject to delays for causes beyond
Landlord's reasonable control) and notify Tenant that it will be doing so, such
notice to be mailed within thirty (30) days from the date of such damage or
destruction, and this Lease shall remain in full force and effect, but the Rent
for the period during which the Premises are untenantable shall be abated pro
rata (based upon the portion of the Premises which is untenantable), except if
more than fifty percent (50%) of the Premises is rendered untenantable, all Rent
shall abate.

                  B. If the Premises cannot reasonably be expected to be made
tenantable within one hundred eighty (180) days from the date of such event,
either Party, by notice in writing to the other mailed within thirty (30) days
from the date of such damage or destruction, may terminate this Lease effective
upon a date within thirty (30) days from the date of such notice.

         11.02 Complex Destruction. In the event that the Building is damaged or
destroyed by fire or other casualty to the extent of more than one-third (1/3)
of the value of the Building, and irrespective of whether damage or destruction
can be made tenantable within one hundred eighty (180) days thereafter, then at
Landlord's option, by written notice to Tenant, mailed within thirty (30) days
from the date of such damage or destruction, Landlord may terminate this Lease
effective upon a date within ninety (90) days from the date of such notice to
Tenant.

         11.03 Duty to Repair; Rent Abatement. If fire or other casualty shall
render the whole or any part of the Premises untenantable and the Premises
cannot reasonably be expected to be made tenantable within one hundred eighty
(180) days from the date of such event and neither party terminates this Lease
pursuant to Section 11.02 hereof; or in the event that the Building is damaged
or destroyed by fire or other casualty to the extent of more than one-third
(1/3) of the value of the Building and Landlord does not terminate this Lease
pursuant to Section 11.02 hereof, then Landlord shall repair and restore the
Premises and the Facility to as near their condition prior to the fire or other
casualty as is reasonably possible, the work to be commenced and prosecuted with
all due diligence and speed (subject to delays for causes beyond Landlord's
reasonable control), and the Rent for the period during which the Premises are
untenantable shall be abated pro rata (based upon the portion of the Premises
that is untenantable),

                                      -22-
<PAGE>   23

except if more than fifty percent (50%) of the Premises is rendered
untenantable, all Rent shall abate. In no event shall Landlord be obligated to
repair or restore any special equipment or improvements installed by Tenant at
Tenant's expense.

         11.04 Proration upon Termination. In the event of a termination of this
Lease pursuant to this Article XI, Rent, to the extent not abated, shall be
apportioned on a per diem basis and paid to the date of termination.

                                   ARTICLE XII
                                 EMINENT DOMAIN

         12.01 Public Taking. All damages except as specifically provided in
Section 12.03 hereinafter, awarded for such taking under the power of eminent
domain or any like proceedings shall belong to and be the property of Landlord,
Tenant hereby assigning to Landlord its interest, if any, in said award. In the
event that fifty percent (50%) or more of the Building area or fifty percent
(50%) or more of the value of the Facility is taken by public authority under
the power of eminent domain, then, at Landlord's option, by written notice to
Tenant, mailed within thirty (30) days from the date possession shall be taken
by such public authority, Landlord may terminate this Lease effective upon a
date within ninety (90) days from the date of such notice to Tenant.

         12.02 Tenant's Election. Further, if the whole or any material part of
the Premises or of the parking available to occupants of the Premises is taken
by public authority under the power of eminent domain, or taken in any manner
for any public or quasi-public use, so as to render the remaining portion of the
Premises unsuitable in Tenant's reasonable opinion, for the Tenant's operations,
upon delivery of possession to the condemning authority pursuant to the
proceedings, Tenant may, at its option, terminate this Lease as to the remainder
of the Premises by written notice to Landlord, such notice to be given to
Landlord within thirty (30) days after Tenant receives notice of the taking.
Tenant shall not have the right to terminate this Lease pursuant to the
preceding sentence unless (i) the business of Tenant conducted in the portion of
the Premises taken cannot in Tenant's reasonable judgment be carried on with
substantially the same utility and efficiency in the remainder of the Premises
(or any substitute space securable by Tenant pursuant to clause (ii) hereof),
and (ii) Tenant cannot secure substantially similar (in Tenant's reasonable
judgment) alternate space upon the same terms and conditions as set forth in
this Lease (including rental) from Landlord in the Facility. Any notice of
termination shall specify a date no more than one hundred twenty (120) days
after the giving of such notice as the date for such termination.

         12.03 Tenant's Damages. Anything in this Article XII to the contrary
notwithstanding, Tenant shall have the right to pursue, apply for and receive a
separate award for damages suffered solely by Tenant in the event of an eminent
domain or condemnation proceeding, including, but not limited to, (i) the cost
of moving, or of

                                      -23-
<PAGE>   24

realigning, removing and relocating Tenant's trade fixtures, equipment and
personal property, and (ii) Tenant's lost or diminished value of Tenant's
leasehold interest or any other matters which are separately compensable solely
to Tenant.

         12.04 Restoration and Rent. Anything in this Article XII to the
contrary notwithstanding, in the event of a partial condemnation of the Facility
or the Premises and this Lease is not terminated, Landlord shall, at its sole
cost and expense, restore the Premises and Facility to a complete architectural
unit and the Base Rent provided for herein during the period from and after the
date of delivery of possession pursuant to such proceedings to the termination
of this Lease shall be reduced to a sum equal to the product of the Base Rent
provided for herein multiplied by a fraction, the numerator of which is the
rentable square footage of the Premises after such taking and after the same has
been restored to a complete architectural unit, and the denominator of which is
the rentable square footage of the Premises prior to such taking.

                                  ARTICLE XIII
                              SURRENDER OF PREMISES

         13.01 Surrender by Tenant. On or before the date thirty (30) days prior
to the date Tenant vacates the Premises, Tenant shall arrange a meeting with
Landlord to review the condition of the Premises. On the last day of the Term of
this Lease, or on the sooner termination thereof, Tenant shall peaceably
surrender the Premises in good condition and repair consistent with Tenant's
duty to make repairs as herein provided, ordinary wear and tear excepted. On or
before the last day of the Term of this Lease, or the date of sooner termination
thereof, Tenant shall at its sole cost and expense, remove all of its property
and trade fixtures and equipment from the Premises and all property not removed
shall be deemed abandoned. Tenant hereby appoints Landlord its agent to remove
all property of Tenant from the Premises upon termination of this Lease and to
cause its transportation and storage for Tenant's benefit, all at the sole cost
and risk of Tenant, and Landlord shall not be liable for damage, theft,
misappropriation or loss thereof, and Landlord shall not be liable in any manner
in respect thereto except to the extent caused by Landlord's negligence. Tenant
shall pay all costs and expenses of such removal, transportation and storage.
Tenant shall leave the Premises in good order, condition and repair, reasonable
wear and tear and damage from fire and other casualty not caused by Tenant
excepted. Tenant shall reimburse Landlord upon demand for any expenses
reasonably incurred by Landlord with respect to removal, transportation, or
storage of abandoned property and with respect to restoring said Premises to
good order, condition and repair. All alterations, additions and fixtures, other
than Tenant's trade fixtures and equipment, that have been made or installed by
either Landlord or Tenant upon the Premises, shall remain the property of
Landlord and shall be surrendered with the Premises as a part thereof. If the
Premises are not surrendered at the end of the Term or sooner termination
thereof, Tenant shall indemnify Landlord against loss or liability resulting
from delay by Tenant in so surrendering the Premises, including, without
limitation, claims made by any

                                      -24-
<PAGE>   25

succeeding tenants founded on such delay and any attorneys fees resulting
therefrom. Tenant shall promptly surrender all keys for the Premises to Landlord
at the place then fixed for the payment of Rent and shall inform Landlord of
combinations on any vaults, locks and safes left on the Premises.

         13.02 Holding Over. In the event Tenant remains in possession of the
Premises after expiration of this Lease, and without the execution of a new
lease, but with Landlord's written consent, it shall be deemed to be occupying
the Premises as a Tenant from month-to-month, subject to all the provisions,
conditions and obligations of this Lease insofar as the same can be applicable
to a month-to-month tenancy, except that the Rent shall be escalated to
Landlord's then current Rent for the Premises according to Landlord's then
current rental rate schedule for prospective tenants. In the event Tenant
remains in possession of the Premises after the termination of this Lease and
without the execution of a new lease and without Landlord's written consent,
Tenant shall be deemed to be occupying the Premises without claim of right and
Tenant shall pay Landlord for all costs arising out of loss or liability
resulting from delay by Tenant in so surrendering the Premises as above provided
and shall pay a charge for each day of occupancy an amount equal to double the
Rent payable immediately prior to the termination of this Lease (on a daily
basis).

                                   ARTICLE XIV
                                     DEFAULT

         14.01 Remedies Cumulative; No Waiver. All rights and remedies of
Landlord herein enumerated shall be cumulative and are not intended to be
exclusive of any other remedies or means of redress to which Landlord may
lawfully be entitled in case of any breach or threatened breach of Tenant of any
provision of this Lease. The failure of Landlord to insist in any one or more
cases upon the strict performance of any of the covenants of this Lease or to
exercise any option herein contained shall not be construed as a waiver or
relinquishment for the future of such covenant or option. A receipt by Landlord
of Rent with knowledge of the breach of any covenant hereof (other than breach
of the obligation to pay the portion of such Rent paid) shall not be deemed a
waiver of such breach, and no waiver by Landlord of any provisions of this Lease
shall be deemed to have been made unless expressed in writing and signed by
Landlord. The consent or approval of Landlord to or of any act of the Tenant
requiring Landlord's consent or approval shall not be deemed to waive or render
unnecessary Landlord's consent or approval to or of any subsequent similar act
by Tenant or his successors. In addition to the other remedies in this Lease
provided, Landlord shall be entitled to the restraint by injunction of the
violation or attempted or threatened violation of the covenants, conditions and
provisions of this Lease.

         14.02 Tenant Change in Status. If, during the Term of this Lease or any
renewal Term, (i) Tenant shall make an assignment for the benefit of creditors
(but this shall not include an assignment made solely for collateral purposes),
or (ii) a voluntary

                                      -25-
<PAGE>   26

petition be filed by Tenant under any law having for its purpose the
adjudication of Tenant a bankrupt, or Tenant be adjudged a bankrupt pursuant to
an involuntary petition in bankruptcy and the same not be dismissed or stayed
within sixty (60) days of its filing, or (iii) a receiver be appointed for the
property of Tenant by reason of the insolvency of Tenant, or (iv) any department
of the state or federal government, or any officer thereof, duly authorized,
shall take possession of the business or property of Tenant by reason of the
insolvency of Tenant and such action not be stayed or terminated within sixty
(60) days thereafter, then, the occurrence of any of such contingencies shall be
deemed a breach of this Lease and this Lease shall ipso facto upon the happening
of any of said contingencies be terminated and the same shall expire as fully
and completely as if the day fixed for the termination of the Initial Term of
this Lease or any renewal thereof; as the case may be, had occurred, and Tenant
will then quit and surrender the Premises, but Tenant shall remain liable as
hereinafter provided. As used in this Section, the term "Tenant" shall also mean
any guarantor of Tenant's obligations under this Lease.

         14.03 Tenant Breach. If, during the Initial Term of this Lease or any
renewal Term, (i) Tenant defaults in any payment of the Rent expressly reserved
hereunder, or any part of the same and such default shall continue for ten (10)
days after written notice thereof by Landlord; (ii) Tenant shall default in
fulfilling any of the covenants, obligations, or agreements of this Lease (other
than the covenants for the payment of Rent payable by Tenant hereunder), or
(iii) this Lease, without the prior written consent of Landlord or except as
expressly permitted herein, shall be assigned, pledged, mortgaged, transferred,
or sublet in any manner, and such default in (ii) shall continue for thirty (30)
days after service of notice of the default by Landlord, or in the event of a
default or contingency set forth in (ii) hereinabove cannot with due diligence
be cured within a period of thirty (30) days, if Tenant fails to proceed
promptly after the service of said notice and with all due diligence to commence
to cure the same and thereafter to prosecute the curing of such default with all
due diligence (it being intended that in connection with a default not
susceptible of being cured with diligence within thirty (30) days, the time
within which Tenant is to cure the same shall be extended for such period as may
be necessary to complete the same with all due diligence), Landlord, at its
option, may pursue the remedies as set forth hereinafter.

         14.04 Remedies upon Default. In the event of a default by Tenant as set
forth hereinabove Landlord at its option may (i) terminate this Lease and upon
such termination Tenant will quit and surrender the Premises to Landlord but
Tenant shall remain liable as hereinafter provided, or (ii) without terminating
the Lease, Landlord or Landlord's agent or servant may re-enter the Premises and
remove all persons and all or any property therefrom, either by summary
dispossession proceedings or otherwise, without being liable to indictment,
prosecution, or damage therefore and repossess and enjoy the Premises, together
with all additions, alterations and improvements, without such re-entry and
repossession working a forfeiture or waiver of the Rents to be paid and the
covenants to be performed by Tenant during the full Term of this Lease.

                                      -26-
<PAGE>   27

         A. Upon termination of this Lease or expiration of Tenant's right to
occupy the Premises by reason of the happening of any of the foregoing events,
or in any other manner or circumstances whatsoever, whether with or without
legal proceedings, by reason of or based upon or arising out of a default or
breach of this Lease on the part of Tenant, Landlord may, at its option, at any
time and from time to time relet the Premises or any part or parts thereof, for
the account of Tenant or otherwise, and receive and collect the Rent therefor,
applying the same first to the payment of such expenses as Landlord may have
reasonably incurred in recovering possession of the Premises, including the
commercially reasonable attorney's fees and expenses for putting the same into
good order and condition or preparing or altering the same for re-rental to the
extent Landlord deems necessary or desirable and all other commercially
reasonable expenses, commissions and charges paid, assumed or incurred by
Landlord in or about reletting the Premises and then to the fulfillment of the
covenants of Tenant hereunder. Any such reletting herein provided for may be for
the remainder of the Initial Term or any renewal Term of this Lease, as
originally granted, or for a longer or shorter period; Landlord shall have the
right to change the character and use made of the Premises, and Landlord shall
not be required to accept any substitute tenant offered by Tenant or to observe
any instructions given by Tenant about reletting. Notwithstanding the foregoing,
Landlord agrees to use commercially reasonable efforts to re-let the Premises
and otherwise mitigate its damages.

         B. In any such case, and whether or not the Premises or any part
thereof be relet, Tenant shall pay to Landlord Rent and other charges required
to be paid by Tenant up to the later of the time of such termination of the
Lease or of such recovery of possession of the Premises by Landlord, as the case
may be, and thereafter, except in a case in which liability of Tenant (as
hereinafter provided), arises by reason of the happening of the insolvency of
Tenant, Tenant covenants and agrees, if required by Landlord, and subject to
Landlord's statutory duty to mitigate damages, to pay to Landlord until the end
of the Initial Term of this Lease, and/or any renewal Term, as the case may be,
the equivalent of the amount of all Rent reserved hereunder, and all other
charges required to be paid by Tenant, less the net proceeds of reletting, if
any. Landlord shall have the election in place of and instead of holding Tenant
so liable forthwith to recover against Tenant as damages for loss of the bargain
and not as a penalty, an aggregate sum which at the time of such termination of
this Lease or of such recovery of possession of the Premises by Landlord, as the
case may be, represents the then present worth of the excess, if any, of the
aggregate of the Rent and all other charges payable by Tenant hereunder that
would have accrued for the balance of the Initial Term, and/or any renewal Term,
as the case may be, over the then present worth of the fair market Rents and all
other charges for the Premises for the balance of such Term.

         14.05 Remedies Upon Insolvency. If this Lease shall terminate by reason
of the bankruptcy or insolvency of Tenant, as above set forth, Landlord shall be
entitled,

                                      -27-
<PAGE>   28

notwithstanding any other provisions of this Lease or any present or future law,
to recover from Tenant or Tenant's estate (in lieu of the equivalent of the
amount of all Rent unpaid at the time of such termination) as damages for loss
of the bargain, and not as a penalty, an aggregate sum which, at the time of
such termination of this Lease, represents the excess, if any, of the then
present worth of the aggregate of the Rent and other charges payable by Tenant
hereunder that would have accrued for the balance of the Initial Term and any
renewal Term, as the case may be, over the then present worth of the fair market
Rents and all other charges for the Premises for the balance of the Initial Term
and any renewal Term, as the case may be, unless any statute or rule of law
governing the proceedings in which such damages are to be proved shall limit the
amount of such claim capable of being so proved. In such case, Landlord shall be
entitled to prove, as and for liquidated damages by reason of such breach and
termination of this Lease, the maximum amount allowed by any such statute or
rule of law which may govern the proceedings in which such damages are to be
proved whether or not such amount be greater, equal to, or less than the amount
of the excess of the then present worth of the Rent and all other charges
reserved herein over the then present worth of the fair market Rents and all
other charges, referred to above.

         14.06 Fees and Expenses; Late Fee. Tenant shall pay, upon demand, all
of Landlord's costs, charges and expenses, including reasonable attorney's fees
and fees of agents and others retained by Landlord, incident to the enforcement
of Tenant's obligations hereunder or incurred by Landlord in any litigation,
negotiation or transaction in which Tenant causes Landlord without Landlord's
fault to become involved or concerned. The prevailing party in any litigation
concerning this Lease shall recover all reasonable attorney fees and other
expenses in addition to costs taxable at law. In addition to the foregoing
remedies, if any payment of Rent is not paid within ten (10) days after the time
it is due, Tenant shall pay a late charge equal to five percent (5%) of the
amount of such overdue payment per month or portion thereof as liquidated
damages for Landlord's extra expense and handling of such past due amount.

         14.07 Landlord's Default. Landlord shall be deemed to be in default
under this Lease if Landlord shall fail to perform any of its obligations under
this Lease within thirty (30) days after written notice specifying such default
from Tenant, or such longer period of times as is reasonable if the default is
not reasonably susceptible of cure within thirty (30) days, Landlord commences
cure within such thirty (30) day period and diligently pursues cure to
completion. Upon such default, Tenant shall be entitled to all remedies at law
or in equity, including but not limited to termination, suit for specific
performance, injunctive relief, and damages, and right to cure such default at
Tenant's expense and set-off such expenses against the next amounts coming due
under this Lease.

                                   ARTICLE XV
                        SUBORDINATION AND ESTOPPEL; LIENS

         15.01 Subordination of Lease. This Lease shall be subject and
subordinate to any mortgage or deed of trust now or hereafter placed upon the
Building or Facility, or any portion thereof by Landlord, its successors or
assigns and to the Ground Lease and to amendments, replacements, renewals and
extensions thereof; provided, however, that the mortgagee, trust deed holder or
Ground Lease lessor agrees in writing with the Tenant or adequate provision is
made in the mortgage, trust deed or Ground Lease so that regardless of any
default or breach under such mortgage, trust deed or Ground Lease or of any
possession or sale of the whole or part of the Premises under or through the
mortgage, trust deed or Ground Lease, this Lease and Tenant's possession shall
not be disturbed by the mortgagee, trust deed holder or the Ground Lease lessor
or any other party claiming by, under or through the mortgage, trust deed or
Ground Lease; provided further, however, that Tenant shall continue to observe
and perform Tenant's obligations under the Lease and pay rent to whomsoever may
be lawfully entitled to the same from time to time.

                  A. Tenant agrees at any time hereafter, upon demand, to
execute and deliver any instruments, releases, or other documents that may
reasonably be required for the purpose of subjecting and subordinating this
Lease, as above provided, to the lien of any such mortgage or deed of trust or
to the Ground Lease. The above subordination shall be effective without the
necessity of the execution and delivery of any further instruments on the part
of Tenant to effectuate such subordination.

                  B. Provided that the mortgagee, trust deed holder under any
mortgage, deed of trust or holder of any other security interest shall have
notified Tenant in writing of its address, Tenant shall give such mortgagee,
trust deed holder, or holder of other security interest, simultaneously with
delivery of notice to Landlord, by registered or certified mail, a copy of any
notice of default by Landlord of any provision under this Lease and the period
that Landlord has to cure such default. Further, Tenant shall give the lessor
under the Ground Lease, to the last known address of the Landlord under the
Ground Lease (a copy of which has been provided to Tenant), simultaneously with
delivery of notice to Landlord, by registered or certified mail, a copy of any
notice of default by Landlord of any provision under this Lease and the period
that Landlord has to cure such default at the address set forth in the Ground
Lease or other address given by the Ground lessor.

                  C. Landlord and Tenant agree from time to time upon not less
than twenty (20) days prior written request by the other to deliver to the other
a statement in writing certifying (i) this Lease is unmodified and in full force
and effect (or if there have been modifications, that the Lease as modified is
in full force and effect and stating the modification); (ii) the dates to which
the Rent and other charges have been paid; (iii) the

                                      -29-
<PAGE>   30

non-requesting party has no knowledge that the requesting party is in default in
any provision of this Lease or, if in default, the nature thereof specified in
detail; (iv) the amount of monthly Rent currently payable by Tenant; (v) the
amount of any prepaid Rent; and (vi) such other matters as may reasonably be
requested by the requesting party or any mortgagee or prospective purchaser of
the Facility; it being intended that any such statement delivered pursuant to
this Section 15.01 may be relied upon by third parties, including but not
limited to any prospective purchaser of the Landlords interest in the Ground
Lease or of the fee of the Facility, or any mortgagee or assignee of the
Landlord.

         15.02 Liens. Tenant shall not do any act which shall in any way
encumber the title of Landlord in and to the Premises, nor shall any interest or
estate of Landlord in the Premises be in any way subject to any claim by way of
lien or encumbrance, whether by operation of law or virtue of any express or
implied contract by Tenant. Any claim to or lien upon the Premises arising from
any act or omission of Tenant shall accrue only against the leasehold estate of
Tenant and shall in all respects be subject and subordinate to the paramount
title and rights of Landlord in and to the Premises. Tenant will not permit the
Premises to become subject to any mechanics', laborers' or materialman's lien on
account of labor or material furnished to Tenant or claimed to have been
furnished to Tenant in connection with work of any character performed or
claimed to have been performed on the Premises by or at the discretion of
Tenant; provided, however, that Tenant shall have the right to contest in good
faith and with reasonable diligence, the validity of any such lien or claimed
lien. Tenant may provide, at Tenant's expense, a bond for the same, which bond
satisfies all statutory requirements, from a bonding company licensed in
Wisconsin and reasonably acceptable to Landlord or affirmative title insurance
coverage from a title insurance company licensed to do business in the state of
Wisconsin. On any final determination of the lien or claim for lien, Tenant will
immediately pay any judgment rendered, with all property costs and charges, and
will, at Tenant's expense, have the lien released any judgment satisfied.

                  If Tenant shall then fail to contest the validity of any lien
or claimed lien within thirty (30) days after obtaining actual knowledge of the
same, or provide a bond or affirmative title insurance coverage for the same
within thirty (30) days of Landlord's request for the same; shall fail to
prosecute such contest with diligence; or shall fail to release all liens within
ninety (90) days (or such longer period as is necessary provided that Tenant
proceeds with diligence) of their filing (unless bonded or insured against as
provided in this Section 15.02 for a longer period); or satisfy any judgment
rendered thereon within thirty (30) days of the date rendered, then Tenant shall
be in default thereunder and Landlord may, at Landlord's election (but not at
Landlord's obligation), remove or discharge such lien or claim for lien (with
the right in Landlord's discretion, to settle or compromise the same), and any
amounts advanced by Landlord for such purposes, including reasonable attorney's
fees, shall be paid by Tenant to Landlord at the next rent date after any such
payment by Landlord.

         15.03 Landlord's Subordination. Landlord agrees, upon request of
Tenant, to subordinate its lien rights with respect to Tenant's property,
whether statutory or otherwise, to the security interest of Tenant's lender or
vendor, subject, however, to Sec. 704.05, Wisc. Stats., relating to storage lien
in favor of Landlord against Tenant's personal property if Tenant removes from

Operating Expense.

                  U. If either Landlord or Tenant shall be delayed or hindered
in or prevented from the performance of any act required hereunder by reason of
any strike, lockout, labor trouble, inability to procure materials, failure of
power, restrictive governmental laws or regulation, riot, insurrection,
picketing, sit-in, war or other reason of a like nature not attributable to the
negligence or fault of the party delayed in performing work or doing any act
required under the terms of this Lease, then the performance of such work or act
shall be excused for the period of the unavoidable delay and the period for the
performance of any such work or act shall be extended for an equivalent period.
However, this provision shall not operate to excuse Tenant from the timely
payment of Rent or other payments required by the terms of this Lease, subject
to other provisions of this Lease governing abatement of Rent.

                  V. Tenant shall not commit or suffer to be committed any waste

not set forth the amount of Base Rent.

                  X. This Lease may be executed in any number of counterparts,

         to be repaired at Tenant's expense and if Tenant fails to cause such
         damage to be repaired promptly upon Landlord's demand therefore,
         Landlord may, in addition to any other rights or remedies available to
         Landlord under this Lease or at law or equity, cause such damage to be
         repaired, in which event Tenant shall promptly, upon Landlord's demand,
         pay to Landlord the cost of such repairs.

                  (c) All contractors and subcontractors shall use only those
         service corridors and service entrances designated by Landlord for
         ingress and egress of personnel and the delivery and removal of
         equipment and material through or across any common areas of the
         Building, and shall only be permitted with the written approval of
         Landlord and during hours determined by Landlord. Landlord shall have
         the right to order Tenant or any contractor or subcontractor who
         violates the above requirements to cease work and to remove it, its
         equipment, and its employees from the Building.

                  (d) Landlord shall allow Tenant to have use of the freight
         elevator serving the Building. Scheduling of Tenant's work in the
         Premises and the use of said freight elevator shall be at the
         reasonable discretion of Landlord or its Contractor.

                  (e) During the performance of Tenant's work and Tenant's
         fixturing, Landlord may provide trash removal service from a location
         designated by Landlord. Tenant shall be responsible for breaking down
         boxes and placing trash in Landlord's containers at such designated
         location. Tenant shall accumulate its trash in containers supplied by
         Tenant and Tenant shall not permit trash to accumulate within the
         Premises or in the corridors or public areas adjacent to the Premises.
         Tenant shall cause each entity employed by it to perform work on the
         Premises to abide by the provisions of the Work Letter as to the
         storage of trash and shall require each such entity to perform its work
         in a way that dust or dirt is contained entirely within the Premises
         and not within any other portion of the Building and shall cause
         Tenant's general contractor to leave the Premises broom clean at the
         end of each day. Should Landlord deem it necessary to remove Tenant's
         trash because of accumulation, an additional charge to Tenant will be
         on a time and material basis. At Landlord's sole direction, Tenant
         shall be responsible for contracting

<PAGE>   54

         independently for such services. The cost to Tenant for Landlord's
         providing such service, if any, will be based on reasonable and
         competitive service Tenant could have secured independently had
         Landlord not provided such service.

                  (f) Tenant agrees that all services and work performed on the
         Premises by, on behalf of, or for the account of Tenant, including
         installation of telephones, carpeting, materials, and personal property
         delivered to the Premises shall be done in a first-class workmanlike
         manner using only good grades of material.

                  (g) Tenant agrees to protect, indemnify, defend and hold
         Landlord and its agents, partners, and employees harmless from and
         against any and all losses, damages, liabilities, claims, liens, costs,
         and expenses, including reasonable attorney's fees of whatever nature
         including those to the person and property of Tenant, its employees,
         agents, invitees, licensees and others arising out of or in connection
         with the activities of Tenant or Tenant's contractors in or about the
         Premises or the Facility and the cost of any repairs to the Premises or
         the Facility necessitated by activities of Tenant or Tenant's
         contractors.

                  (h) Tenant shall secure, pay for, and maintain during the
         continuance of its work within the premises, policies of insurance with
         such coverages and such amounts as Landlord may reasonably require,
         which policies shall be endorsed to include Landlord and its contractor
         and their respective employees and agents as additional insured parties
         and which shall provide thirty (30) days prior written notice of any
         alteration or termination of coverage, in such amounts and insuring
         such risks as Landlord may require, Tenant shall not permit Tenant's
         contractors to commence any work until all required insurance has been
         obtained by Tenant and certificates evidencing such coverage have been
         delivered to Landlord.

         6. Acceptance of Work. When Landlord is of the opinion that the Work is
completed, then the Landlord shall so notify Tenant. Tenant agrees that upon
such notification, Tenant, with its architect, shall promptly (and not later
than Three (3) business days after the date of Landlord's said notice) inspect
the Premises and furnish to Landlord a list of all items of Work which remain
unfinished and/or which are in need of correction or repair (hereinafter
referred to as the "Punch List"). Tenant agrees that at the request of Landlord
from time to time thereafter, Tenant will promptly furnish to Landlord revised
Punch Lists reflecting completion of any prior Punch List items. It is mutually
agreed that if the Punch List or any revised Punch List consists only of items
that can be completed within a relatively short period of time, and if the
non-completion of such Punch list items would not materially impair Tenant's use
or occupancy of the Premises, then, in such event, Tenant will acknowledge in
writing that

<PAGE>   55

the Work is substantially completed and accepts possession of the Premises,
provided however, that such acknowledgment or acceptance shall not relieve
Landlord of its obligations to promptly complete all such Punch List items. The
Work shall be deemed to be substantially completed on the date (the "Substantial
Completion Date") which is the earlier of either (i) the date on which Tenant
acknowledges that the Work is so substantially completed, or (ii) the date on
which the Work is determined to be substantially completed by Landlord's
architect or interior space planner for the Building (with the concurrence of
Tenant's Interior Space Planner [in the exercise of its reasonable judgment])
pursuant to the provisions of this Paragraph 6.

         7. Miscellaneous.

                  (a) Except as expressly set forth herein and in the Lease,
         Landlord has no other agreement with Tenant and has no other obligation
         to do any other work or pay any amounts with respect to the Premises.
         Any other work in the Premises which may be permitted by Landlord
         pursuant to the terms and conditions of the Lease shall be done at
         Tenant's sole cost and expense and in accordance with the terms and
         conditions of the Lease.

                  (b) This Work Letter shall not be deemed applicable to the
         Storage Space or to any additional space added to the original Premises
         at any time or from time to time, whether by any options under the
         Lease or otherwise, or to any portion of the original Premises or any
         additions thereto in the event of a renewal or extension of the Initial
         term of the Lease, whether by any options under the Lease or otherwise,
         unless expressly so provided in the Lease or any amendment or
         supplement thereto.

                  (c) The failure by Tenant to pay any monies due Landlord
         pursuant to this Work Letter within the time period herein stated shall
         be deemed a default under the terms of the Lease for which Landlord
         shall be entitled to exercise all remedies available to Landlord for
         nonpayment of rent. All late payments shall bear interest and shall be
         subject to late charges as provided in the Lease.

                  (d) This Work Letter is being executed in conjunction with the
         Lease and is subject to each and every term and condition thereof,
         including, without limitation, the limitations of liability set forth
         therein.

                  (e) Tenant shall be solely responsible to determine at the
         site all dimensions of the Premises and the Building that affect any
         work to be performed by or for Tenant hereunder.

         IN WITNESS WHEREOF, the parties hereto have executed this Lease to be
effective on the day and year first above written.

                               TERMS OF EMPLOYMENT

During the quarter ended March 31, 2001, SBS employed Mr. Grahame Rance as its
President and CEO. The parties have not completed the formal employment
agreement, but have agreed substantially on the following terms:

1.       Mr. Rance is employed as SBS's President and CEO, effective March 9,
         2001, with a signing bonus of $200,000, pretax, and at an initial base
         salary of $500,000. He will also serve as a Director.

2.       SBS will grant Employee 300,000 options, vesting over six years, on SBS
         Common Stock, at an exercise price of $18.125, the closing price on the
         day before Mr. Rance's first day of employment. In addition, Mr. Rance
         will receive an annual grant of options for 40,000 shares of SBS common
         stock, each vesting over two years, at an exercise price equal to fair
         market value on the date of grant.

3.       SBS will provide to Mr. Rance, pretax, additional compensation of $2.4
         million, which will be in the form of a combination of between 30,000
         and 50,000 restricted SBS shares, a loan, and other possible elements.
         The shares will vest, and the loan will be forgiven, over a six-year
         period on the anniversaries of Mr. Rance's employment, and part of the
         shares will vest, and part of the loan be forgiven, upon termination of
         Mr. Rance's employment under certain circumstances. Termination of
         employment by SBS will include six months termination pay at the normal
         annual base pay in effect at the time. If SBS is acquired by another
         organization during the six-year period, the remaining loan amount will
         be forgiven and restrictions on shares will be removed as provided in
         the 2000 Long-Term Equity Incentive Plan.

4.       Mr. Rance will be located in SBS' facility in Carlsbad, California. SBS
         will pay moving and certain home mortgage and home maintenance
         expenses, as well as provide standard and additional employment
         benefits.

SBS and Mr. Rance are in process of negotiating the final employment agreement.
The final agreement is expected to be filed with SBS' Form 10-K on or before
September 28, 2001.
