Option, in which event Tenant's right to exercise the Renewal Option shall be
deemed to be null and void and of no further force or effect. If Tenant elects
to exercise the Renewal Option within the time period set forth herein, the Base
Rent shall be adjusted for the first annual period of the Renewal Term to an
amount which is equal to the CMRR, and for each succeeding annual period of the
Renewal Term, the Base Rent shall be adjusted to one hundred three percent
(103%) of the immediately preceding annual Base Rent amount. If Tenant neither
elects to exercise its Renewal Option nor elects not to exercise its Renewal
Option, such inaction shall be deemed an election to not exercise the Renewal
Option.

underground reserved parking spaces as may then be available, that Landlord is

of time which corresponds to the remaining Lease Term hereof.

     (b) Tenant shall have five (5) Business Days following its receipt of the
Offer Notice to notify Landlord, in writing, that Tenant elects to lease all
(but Tenant shall have no right to elect to lease less than all) of the
Opportunity Space. If Tenant fails to notify Landlord within such five (5)
Business Day period, Tenant shall be deemed to have elected not to exercise its
Opportunity Right and Landlord shall be free to lease the applicable Opportunity
Space to any third party within one hundred twenty (120) days following
delivery of the Offer Notice; provided that Landlord shall not grant any
renewal rights beyond an initial term with respect to any lease of the
Opportunity Space, and this Section 2.13 will continue to apply upon expiration
of any lease of the Opportunity Space to a third party.

     (c) If Tenant does exercise its Opportunity Right by providing written
notice to Landlord within such five (5) Business Day period, the Opportunity
Space shall be added to the Premises at the equivalent Base Rent amount (on a
per square foot basis) then being paid by Tenant to Landlord under this Lease,
and with Tenant being entitled to a pro-rated portion of the Tenant Improvement
Allowance (if the Opportunity Right is exercised during the initial Term only,
but not during any Renewal Term). With respect to the Tenant Improvement
Allowance, by way of illustration, if the Opportunity Right is exercised with 13
months left in the initial Term of this Lease, Tenant will be entitled to an
allowance equal to $7.00 for each square foot of the Opportunity Space (13/65
months = .20 x $35.00 = $7.00). Except as set forth herein, the Opportunity
Space shall be leased to Tenant on all of the same terms and conditions set
forth in this Lease.

     (d) Subject to Landlord providing an improvement allowance as set forth in
Landlord's Offer Notice, any Opportunity Space shall be leased to Tenant "as-is"
and any improvements desired by Tenant shall be constructed subject to the terms
and conditions set forth elsewhere in this Lease. The commencement date for the
Opportunity Space shall be the earlier of sixty (60) days after Landlord makes
the applicable

                                      -7-

Opportunity Space available to Tenant for the construction of leasehold
improvements or the date Tenant begins conducting business in the Opportunity
Space.

     (e) Notwithstanding anything contained in this Section 2.1 to the contrary,
unless Tenant has exercised its Renewal Option pursuant to Section 2.12 hereof,
the Opportunity Right granted herein shall expire automatically on the Renewal
Option Exercise Date.

SECTION 3: BASE RENT, ADDITIONAL RENT AND OTHER SUMS PAYABLE UNDER LEASE

     3.1 PAYMENT OF RENTAL. Tenant agrees to pay Base Rent, Additional Rent and
any other sum due under this Lease to Landlord without demand, deduction,
credit, adjustment or offset of any kind or nature, in lawful money of the
United States when due under this Lease, at the offices of Manager at Manager's
Address, or to such other party or at such other place as Landlord may from time
to time designate in writing. If this Lease does not specify a due date with
respect to any sum payable by Tenant hereunder, such sum shall be due ten (10)
calendar days after written demand for such payment is given to Tenant.

     3.2 BASE RENT. Tenant agrees to pay Base Rent to Landlord without demand,
in advance on or before the first day of each calendar month of the Lease Term.
Base Rent for any partial month at the beginning or end of the Lease Term shall
be prorated. On execution of this Lease, Tenant has paid to Landlord the amount
specified in the definition of Prepaid Rent for the month specified in the
definition of that term. Base Rent for any partial month at the beginning of the
Lease Term shall be paid by Tenant on the Commencement Date.

     3.3 INTENTIONALLY OMITTED.

     3.4 ADDITIONAL RENT. Definitions of certain terms used in this paragraph
are set forth in subparagraph 3.4.5. Tenant agrees to pay to Landlord additional
rent as computed in this paragraph (individually and collectively the
"Additional Rent"):

          3.4.1 RENTAL ADJUSTMENT FOR ESTIMATED OPERATING COSTS. Landlord shall
furnish Tenant a written statement of Estimated Operating Costs Allocable to the
Premises for each Year and the amount payable monthly by Tenant for such Costs
shall be computed as follows: one-twelfth (1/12) of the amount, if any, by which
the Estimated Operating Costs Allocable to the Premises exceeds the Base Amount
Allocable to the Premises shall be Additional Rent and shall be paid monthly by
Tenant for each month during such Year after the Commencement Date. If Landlord
fails to deliver a written statement of the Estimated Operating Costs for any
Year, Tenant shall continue to make monthly payments on account of the Estimated
Operating Costs in an amount equal to the estimated monthly payment amount
established for the preceding Year. If any such written statement is furnished
after the commencement of the Year (or as to the first Year during the Lease
Term, after the Commencement Date), Tenant shall also make a retroactive
lump-sum payment to Landlord equal to the monthly payment amount multiplied by
the number of months during the Year (or as to the first Year during the Lease
Term, after the Commencement Date) prior to delivery of such written statement,
less any payments made by Tenant for Estimated Operating Costs Allocable to the
Premises for such period.

                                      -8-

<PAGE>   13
          3.4.2 ACTUAL COSTS. Within four (4) months after the close of each
Year, Landlord shall deliver to Tenant a written statement setting forth the
Operating Costs and the Operating Costs Allocable to the Premises during the
preceding Year. If such Operating Costs Allocable to the Premises for any Year
exceed the Estimated Operating Costs Allocable to the Premises paid by Tenant to
Landlord pursuant to subparagraph 3.4.1 for such Year, Tenant shall pay the
amount of such excess to Landlord within thirty (30) calendar days after receipt
of such statement by Tenant. If such statement shows the Operating Costs
Allocable to the Premises to be less than the Estimated Operating Costs
Allocable to the Premises paid by Tenant to Landlord pursuant to subparagraph
3.4.1, then the amount of such overpayment shall be paid by Landlord to Tenant
within thirty (30) calendar days following the date of such statement or, at
Landlord's option, shall be credited towards the installment(s) of Additional
Rent next coming due from Tenant.

          3.4.3 DETERMINATION. The determination of Operating Costs Allocable to
the Premises shall be reasonably made by Landlord. Any sums payable under this
Lease pursuant to this paragraph shall be Additional Rent and, in the event of
nonpayment of such sums, Landlord shall have the same rights and remedies with
respect to such nonpayment as it has with respect to nonpayment of the Base Rent
due under this Lease. Tenant shall have the right to contest any determination
of Operating Costs Allocable to the Premises and the Base Amount allocable to
the Premises within 90 days after delivery of Landlord's statement of same to
Tenant. Landlord shall make its books and records available to Tenant and/or
Tenant's agent at Landlord's place of business during Landlord's normal business
hours. Notwithstanding the foregoing in the event such audit indicates
negligence or fraud on Landlord's part, and the Tenant overpaid by more than 5%
of the actual Operating Costs Allocable to the Premises. Landlord shall
reimburse Tenant for the cost of Tenant's inspection if Landlord's books and
records. In any event, if an audit reveals that any excess amount was
incorrectly charged to Tenant, such excess amount shall be promptly refunded by
Landlord to Tenant.

          3.4.4 END OF TERM. If this Lease shall terminate on a day other than
the last day of a Year, (a) Landlord shall estimate the Operating Costs
Allocable to the Premises for such Year predicated on the most recent reliable
information available to Landlord; (b) the amount determined under clause (a) of
this sentence shall be prorated by multiplying such amount by a fraction, the
numerator of which is the number of calendar days within the Lease Term in such
Year and the denominator of which is 365; (c) the Base Amount Allocable to the
Premises shall be prorated in the manner described in clause (b); (d) the clause
(c) amount (i.e., the prorated Base Amount Allocable to the Premises) shall be
deducted from the clause (b) amount (i.e., the prorated Operating Costs
Allocable to the Premises); (e) if the clause (d) amount exceeds the Estimated
Operating Costs Allocable to the Premises paid by Tenant for the last Year in
the Lease Term, then Tenant shall pay the excess to Landlord within thirty (30)
calendar days after Landlord's delivery to Tenant of a statement for such
excess; and (f) if the Estimated Operating Costs Allocable to the Premises paid
by Tenant for the last Year in the Lease Term exceeds the clause (d) amount,
then Landlord shall refund to Tenant the excess within the thirty (30) calendar
day period described in clause (e). Landlord's and Tenant's obligations under
this paragraph shall survive the expiration or other termination of this Lease.

          3.4.5 DEFINITIONS. Each underlined term in this subparagraph shall
have the meaning set forth next to that underlined term:

          BASE AMOUNT ALLOCABLE TO THE PREMISES: ____ (Zero (0) if not filled
          in).

          of the net rentable area of the Building is occupied by tenants at all
          times during any Year, then Operating Costs for such Year shall
          include all additional costs and expenses that Landlord reasonably
          determines would have been incurred had ninety-five percent (95%) of
          the Building been occupied at all times during such Year by tenants;
          it being understood that fixed expenses not dependent upon occupancy
          levels, such as real estate taxes, shall not be included as part of
          the foregoing computation.

          OPERATING COSTS ALLOCABLE TO THE PREMISES: The product of Tenant's Pro
          Rata Share times Operating Costs.

     3.5 UTILITIES.

          3.5.1 Landlord shall have the right from time to time to select the
company or companies providing local telephone and telecommunication services to
the Building. Tenant shall contract directly and pay for all telephone and other
telecommunication services used on or from the Premises together with any taxes,
penalties, surcharges or similar charges relating to such services. If Tenant
desires to use the services of a provider of local telephone or
telecommunication services whose equipment is not then servicing the Building,
no such provider shall be permitted to install its lines or other equipment
within the Building without the prior written consent of Landlord, which consent
shall not be unreasonably withheld or delayed.

          3.5.2 Tenant shall, as part of the Tenant Improvements, install
necessary electricity meter reading devices and separately meter the Premises
for the provision of electricity to the Premises and may use the Landlord's
electrical distribution system with respect to such installation; provided,
however, that Landlord reserves the right to select the electric utility
provider to the Building and that the obligation of Landlord to make available
electricity or other utilities at the Building shall be subject to the rules and
regulations of the supplier of such utilities and of any municipal or other
governmental authority regulating the business of providing such utility
service. Tenant shall pay for electricity based on such meters directly and
shall pay any meter reading charges which may be incurred by Landlord. Tenant
shall not use any electrical equipment which may overload the wiring
installations or electrical load capacity of the system or interfere with the
use of electricity by Landlord or other tenants of the Building. Tenant shall
not at

                                      -11-
<PAGE>   16

any time submeter the Premises without Landlord's prior written consent.
Notwithstanding anything contained herein to the contrary, in any and all
events. Tenant shall be responsible to pay for all electricity, other than
electricity which is used in connection with HVAC and which is included as part
of Tenant's Additional Rent payments hereunder, consumed in the Premises during
the Lease Term. If at any time during the Term the Premises are not separately
metered, or the Tenant's electricity is not being provided by or through such
separate metering, whether temporarily, sporadically or permanently, Tenant
shall pay for electricity based on Landlord's reasonable estimate of Tenant's
usage.

          3.6 HOLDOVER. If Landlord agrees in writing that Tenant may hold
over after the expiration or termination of this Lease, and Landlord and Tenant
do not otherwise agree in writing on the terms of such holding over, then the
hold over tenancy shall be subject to termination by Landlord at any time upon
not less than thirty (30) days advance written notice, or by Tenant at any time
upon not less than thirty (30) days advance written notice, and all of the
other terms and provisions of this Lease shall be applicable during that period,
except that Tenant shall pay Landlord from time to time upon demand, as Base
Rent for the period of any hold over, an amount equal to 150% of the Base Rent
in effect on the termination date, computed on a daily basis for each day of the
hold over period. Such payment shall not release the Tenant from Tenant's
obligation to pay Additional Rent and any other sums due under this Lease. No
holding over by Tenant, whether with or without consent of Landlord, shall
operate to extend this Lease except as otherwise expressly, agreed by Landlord
in writing. The foregoing notwithstanding, if Landlord does not agree in writing
that Tenant may hold over after the expiration or termination of this Lease.
Tenant shall pay the daily Base Rent, Additional Rent and other sums during the
period of such holding over as set forth above, and Landlord shall be entitled
to pursue all remedies at law and in equity to which Landlord is entitled,
including, without limitation, rights to ejectment and damages.

          3.7 LATE CHARGE. If Tenant fails to make any payment of Base Rent,
Additional Rent or other amount within five (5) days of the date when due under
this Lease. Tenant shall also pay a late charge equal to five percent (5%) of
the amount of any such payment; provided that Landlord agrees to waive the late
charge for the first late payment in any Year of this Lease. Landlord and Tenant
agree that this charge compensates Landlord for the administrative costs caused
by the delinquency. The parties agree that Landlord's damage would be difficult
to compute and the amount stated in this paragraph represents a reasonable
estimate of such damage. Assessment or payment of the late charge contemplated
in this paragraph shall not excuse or cure any Event of Default or breach by
Tenant under this Lease or impair any other right or remedy provided under this
Lease or under law.

          3.8 DEFAULT RATE. Any Base Rent, Additional Rent or other sum payable
under this Lease which is not paid within five (5) days of the date when due
shall bear interest at a rate equal to the lesser of: (a) the published prime
rate of Riggs Bank, N.A. or such other national banking institution designated
by Landlord if such bank ceases to publish a prime rate (the "Prime Rate"), then
in effect, plus two (2) percentage points, or (b) the maximum rate of interest
per annum permitted by applicable law (the "Default Rate"), but the payment of
such interest shall not excuse or cure any Event of Default or breach by Tenant
under this Lease or impair any other right or remedy provided under this Lease
or under law.

                         SECTION 4: GENERAL PROVISIONS

          4.1 MAINTENANCE AND REPAIR BY LANDLORD. Subject to the paragraphs
captioned "Damage or Destruction" and "Condemnation", Landlord shall maintain
the public and common areas of the Building

                                      -12-
<PAGE>   17

in reasonably good order and condition, except for damage occasioned by the act
or omission of Tenant or Tenant's Agents which shall be paid for entirely by
Tenant upon demand by Landlord, and ordinary wear and tear. In the event any or
all of the Building becomes in need of maintenance or repair which Landlord is
required to make under this Lease, upon knowledge, discovery or intent to
undertake such maintenance or repair, Tenant or Landlord, as the case may be,
shall promptly give written notice to the other party; it being understood that
Landlord shall not be obligated in any way to commence such maintenance or
repairs until a reasonable time elapses after Landlord's receipt or delivery of
any such notice.

          4.2 MAINTENANCE AND REPAIR BY TENANT. Except as is expressly set forth
as Landlord's responsibility pursuant to the paragraphs captioned "Maintenance
and Repair by Landlord" in paragraph 4.1 hereof, and "Building Service" in
paragraph 4.4 hereof. Tenant shall at Tenant's sole cost and expense keep and
maintain the Premises in good condition and repair. If Tenant fails to maintain
or repair the Premises in accordance with this paragraph, then Landlord may, but
shall not be required to, enter the Premises upon ten (10) calendar days prior
written notice to Tenant (or immediately without any notice in the case of an
emergency) to perform such maintenance or repair at Tenant's sole cost and
expense. Tenant shall pay to Landlord the reasonable cost of such maintenance or
repair within thirty (30) calendar days after written demand from Landlord.

          4.3 COMMON AREAS/SECURITY/PARKING. The common areas of the Building
shall be subject to Landlord's sole management and control. Without limiting
the generality of the immediately preceding sentence, Landlord reserves the
exclusive right as it deems necessary or desirable to install, construct,
remove, maintain and operate lighting systems, facilities, improvements,
equipment and signs on, in or to all parts of the common areas; change the
number, size, height, layout, or locations of walks, driveways and truckways or
parking areas now or later forming a part of the Land or Building; make
alterations or additions to the Building or common area; close temporarily all
or any portion of the common areas to make repairs, changes or to avoid public
dedication: grant easements to which the Land will be subject, replat,
subdivide, or make other changes to the Land; place, relocate and operate
utility lines at the Land and Building; and use or permit the use of all or any
portion of the roofs of the Building. Landlord has no duty or obligation to
provide any security services in, on or around the Premises, Land or Building,
and Tenant recognizes that security services, if any, provided by Landlord will
be for the sole benefit of Landlord and the protection of Landlord's property
and under no circumstances shall Landlord be responsible for, and Tenant waives
any rights with respect to, Landlord providing security or other protection for
Tenant or Tenant's Agents or property in, on or about the Premises, Land or
Building. During the Lease Term, as may be extended, and provided that an Event
of Default has not occurred and is not then continuing, Tenant shall be entitled
to eight (8) underground reserved parking spaces at the Building. Landlord shall
maintain a 4.0/1,000 square foot ratio for outdoor surface parking spaces at the
Building and the Land; provided that Landlord reserves the right to relocate
parking areas and driveways and to build additional improvements in the common
areas of the Building and the Land; provided that the parking areas shall remain
in reasonably close proximity to the Building.

     4.4 BUILDING SERVICES.

          4.4.1 Landlord shall use all commercially reasonable efforts to
provide the following services and facilities to the Premises:

                                      -13-
<PAGE>   18

          (a) Heating, ventilating and air conditioning during Business Hours
subject to such regulations as the Department of Energy or other Governmental
Agency shall adopt from time to time. Tenant agrees to cooperate fully with
Landlord and to abide by all the rules and regulations which Landlord may
reasonably prescribe (which rules and regulations shall be uniformly prescribed
and applied) for the proper functioning and protection of the heating,
ventilating and air conditioning systems. If Tenant requires heating,
ventilation and air conditioning service at times other than Business Hours,
Landlord shall use diligent efforts to supply the same upon reasonable prior
notice, to be paid for by Tenant, within ten (10) calendar days of billing, at a
rate to be determined from time to time by Landlord, which rate shall equal
Landlord's reasonably estimated actual cost for such service, which the parties
acknowledge is currently equal to, and shall not in any event exceed, $75.00 per
hour.

          (b) Subject to payment of the charges therefor by Tenant, electricity
for normal office use, including normal office equipment, in the Premises.

          (c) Cleaning and maintenance of common areas in the Building in a
manner consistent with first class buildings in northern Lake County,

          (d) Continuous passenger elevator service during Business Hours, and
service via at least one (1) elevator car at all other times, 24 hours per day,
each day of the Year.

          (e) Janitorial services, including cleaning of the Premises, in
accordance with Exhibit E and consistent with first class buildings in northern
Lake County. Landlord shall furnish cleaning services to kitchens, lunchrooms
and non-Building standard lavatories in the Premises; provided that Landlord
shall not be required to provide cleaning services to any personal items
comprising such kitchens, lunchrooms, and non-Building standard lavatories,
including without limitation, washing dishes, stacking chairs, replacing
accouterments, etc.

          (f) Water for lavatory and drinking purposes.

          4.4.2 Tenant shall reimburse Landlord for any and all additional
cleaning expenses incurred by Landlord, including garbage and trash removal
expenses over and above the normal cleaning provided by Landlord or due to the
presence of a lunchroom or kitchen or food or beverage dispensing machines
within the Premises. No food or beverage dispensing machines shall be installed
by Tenant in the Premises without the prior written consent of Landlord, which
consent shall not be unreasonably withheld or delayed.

          4.4.3 The services described in subparagraph 4.4.1 may be subject to
slowdown interruption or stoppage due to the order of any Governmental Agency,
Force Majeure, or the maintenance, repair, replacement or improvement of any of
the equipment involved in the furnishing of any such service. No such slowdown
interruption or stoppage of any such service shall be construed as an eviction,
actual or constructive, of Tenant, nor shall same cause any abatement of Base
Rent or Additional Rent or relieve Tenant from any of its obligations under this
Lease. Landlord agrees to use all commercially reasonable efforts to resume the
affected service promptly following any such slowdown interruption or stoppage.
Landlord will provide Tenant, whenever reasonably possible, advance notice of
any scheduled service slowdowns, interruptions or stoppages of which it has
knowledge. Notwithstanding anything to the contrary aforesaid, if, as a result
of the negligence of Landlord or Landlord's Agents, there is an interruption or
discontinuance in the furnishing by Landlord of any Building Services (as
described in

                                      -14-
<PAGE>   19

paragraph 4.4.1) to the Premises which results in Tenant being unable to
reasonably operate at the Premises or having vacated the Premises due to such an
interruption or discontinuance, in each case for a period in excess of seven (7)
consecutive full calendar days after notice to Landlord by Tenant, all regularly
payable Base Rent required under this Lease shall abate from the end of such
period until the earlier of the date Tenant reenters and reasonably uses the
Premises, or such time as Building Services are restored, such that Tenant is
again reasonably able to operate at the Premises. If only a portion of the
Premises is untenantable, Base Rent shall be abated in the proportion that the
untenantable rentable area of the Premises bears to the total rentable area of
the Premises.

          4.4.4 Tenant shall be entitled to use a portion of the storage space
in the lower level of the Building (the "Storage Space"), to the extent then
available from time to time, as determined by Landlord in its reasonable
discretion. With respect to any Storage Space made available to Tenant, Tenant
shall pay to Landlord rent in an amount equal to $10.75 for each square foot of
storage space, escalating at a rate of 3% per annum. The rent to be paid for

improvements to the Storage Space unless Tenant causes damage thereto and
provided further that Tenant shall maintain the Storage Space in a good
condition and shall keep the Storage Space free of any rubbish, debris and other

contractor's willingness to enter into Landlord's form of agreement with respect
to construction of the Tenant Alterations. Tenant shall reimburse Landlord, upon
receipt of demand therefor, for all out-of-pocket costs and expenses incurred by
Landlord related to its review of Tenant's plans and specifications (regardless
of whether Landlord approves Tenant's request). Upon completion of the Tenant
Alterations, Tenant shall pay Landlord an amount equal to Landlord's reasonable
out-of-pocket costs in connection with Landlord's coordination, administration
and inspection of such work. Without limiting the generality of the foregoing.
Landlord may require Tenant (if Landlord has elected to require Tenant to
perform the Tenant Alterations), at Tenant's sole cost and expense, to obtain
and provide Landlord with proof of insurance coverage and a payment and
performance bond, in forms, amounts and by companies acceptable to Landlord. All
Tenant Alterations to the Premises, regardless of which party constructed them,
shall become the property of Landlord (except for Tenant's trade fixtures, which
shall remain Tenant's property) and shall remain upon and be surrendered with
the Premises upon the expiration or earlier termination of this Lease; provided
that, upon the expiration or earlier termination of this Lease, at Landlord's
election and upon notice to Tenant (which

consent, Landlord may do so and Tenant shall pay to Landlord the entire cost
thereof plus an administrative charge of five percent (5%) within ten (10)
calendar days after Tenant's receipt of Landlord's written demand therefor.

captioned "Mechanic's Liens".

perform the Tenant Alterations, then the Tenant Alterations shall be performed
by contractors employed by Tenant under one or more construction contracts, in
form and content approved in advance in writing by Landlord (which approval
shall be subject to Landlord's discretion (but shall not be unreasonably
withheld) and may include a requirement that the prime contractor and the
respective subcontractors: (a) be parties to, and bound by, a collective
bargaining agreement with a labor organization affiliated with the Building and
Construction Trades Council of the AFL-CIO and (b) employ only members of such
labor organizations to perform work within their respective jurisdictions).
Tenant's contractors, workers and suppliers shall work in harmony with and not
interfere with workers or contractors of Landlord or other tenants of Landlord.

cause such disharmony or interference, Landlord's consent to the continuation of
such work may be withdrawn upon written notice to Tenant. All Tenant Alterations
shall be (1) completed in accordance with the plans and specifications approved
by Landlord, (2) completed in accordance with all Governmental Requirements; (3)
carried out promptly in a good and workmanlike manner; (4) of all new materials;
(5) free of defect in materials and workmanship; and (6) inspected for quality
control (punchlisted) by Landlord's construction manager. Any and all portions
of the Tenant Alterations not meeting Landlord's quality and building standards
shall be corrected by Tenant, at Tenant's expense, within thirty (30) days
after notification of such defects by Landlord. If Tenant fails to bring the
work in question up to the required standards within such 30 day period.

Tenant shall pay the entire cost thereof to Landlord within ten (10) calendar
days after Tenant's receipt of Landlord's written demand therefor. Tenant shall
pay for all damage to the Premises, Building and Land caused by Tenant or
Tenant's Agents. If Tenant performs the Tenant Alterations, Tenant shall

twenty (20) calendar days prior to vacating the Premises and shall arrange to
meet with Landlord for a joint inspection of the Premises prior to vacating. In
the event of Tenant's failure to give such notice or arrange such joint
inspection, and after the further failure of Tenant to meet with Landlord for a
joint inspection within two (2) days of Landlord's written demand to Tenant for
a joint inspection, Landlord's inspection at or after Tenant's vacating the
Premises shall be conclusively deemed correct for purposes of determining
Tenant's responsibility for repairs and restoration.

     4.8 REMOVAL OF PROPERTY. Upon expiration or earlier termination of this
Lease, Tenant may remove its trade fixtures, affixed personal property, office
supplies and office furniture and equipment if

                                      -16-

other part of the Premises or Building, shall become the property of Landlord

expiration or earlier termination of this Lease or at such time as Landlord
exercises its right of re-entry, Tenant has failed to remove any property from
the Premises, Building or Land which it is entitled or required to remove as
provided in this Lease, Landlord may, at its option, remove and store such
property without liability for loss of or damage to such property, such storage
to be for the account and at the expense of Tenant. If Tenant fails to pay the
cost of storing any such property, Landlord may, at its option, after
reasonable written notice providing an opportunity to cure to Tenant, sell or
permit to be sold, any or all such property at public or private sale (and
Landlord may become a purchaser at such sale), in such manner and at such times
and places as Landlord in its sole discretion may deem proper, without further
notice to Tenant, and Landlord shall apply the proceeds of such sale: first, to
the cost and expense of such sale, including reasonable attorney's fees actually
incurred; second, to the payment of the costs or charges for storing any such
property; third, to the payment of any other sums of money which may then be or
later become due Landlord from Tenant under this Lease; and, fourth, the
balance, if any, to Tenant.

     4.9 ACCESS. Tenant shall permit Landlord and Landlord's Agents to enter
into the Premises at any reasonable time, and upon reasonable prior notice in
any non-emergency situation, for the purpose of inspecting the same or for the
purpose of repairing, altering or improving the Premises or the Building.

upon Landlord not expressly stated elsewhere in this Lease. When reasonably
necessary, Landlord may temporarily close Building or Land entrances, Building
doors or other facilities, without liability to Tenant by reason of such closure
and without such action by Landlord being construed as an eviction of Tenant or
as relieving Tenant from the duty of observing or performing any of the
provisions of this Lease. Landlord shall have the right to enter the Premises
for the purpose of showing the Premises to prospective tenants within the period
of one hundred eighty (180) calendar days prior to the expiration or sooner
termination of this Lease. Landlord shall not be liable for the consequences of
admitting by passkey, or refusing to admit to the Premises. Tenant or any of

          4.10.1 If the Premises are damaged by fire, earthquake or other
casualty, Landlord shall, within forty-five (45) calendar days, estimate whether
the damage can be repaired within two-hundred-seventy (270) calendar days, and
if so, and if there are sufficient insurance proceeds available to repair such
damage, then Landlord shall proceed with reasonable diligence to restore the
Premises to substantially the condition which existed prior to the damage and
this Lease shall not terminate. If, in Landlord's estimation, the damage cannot
be repaired within such 270 day period or if there are insufficient insurance
proceeds available to repair such damage, Landlord may elect in its absolute
discretion to either:

                                      -17-
<PAGE>   22

(a) terminate this Lease or (b) restore the Premises to substantially the
condition which existed prior to the damage and this Lease will continue. If
Landlord restores the Premises under this paragraph, then (1) Tenant shall pay
to Landlord, upon demand, Tenant's Pro Rata Share of any applicable deductible
amount specified under Landlord's insurance and (2) Landlord shall not be
required to repair or restore any or all furniture, fixtures, equipment,
inventory, improvements or other property which was in or about the Premises at
the time of the damage, Tenant Alterations or Tenant Improvements which are in
excess of the Tenant Improvement Allowance, unless Landlord or Landlord's Agents
caused the damage which requires such repair or restoration. Base Rent,
Additional Rent and any other sum due under this Lease during any reconstruction
period shall be abated as equitable under the circumstances. Tenant agrees to
look to the provider of Tenant's insurance for coverage for the loss of Tenant's
use of the Premises and any other related losses or damages incurred by Tenant
during any reconstruction period.

          4.10.2 If the Building is damaged by fire, earthquake or other
casualty and more than fifty percent (50%) of the Building is rendered
untenantable, without regard to whether the Premises are affected by such
damage. Landlord may in its absolute discretion and without limiting any other
options available to Landlord under this Lease or otherwise, elect to terminate
this Lease by notice in writing to Tenant within sixty (60) calendar days after
the occurrence of such damage. Such notice shall be effective thirty (30)
calendar days after receipt by Tenant unless a later date is set forth in
Landlord's notice. If, within the last twelve (12) months of the Term of this
Lease, the Premises is damaged by fire, earthquake or other casualty and more
than one-third (33.33%) of the Premises is rendered untenantable. Tenant may
elect to terminate this Lease by notice in writing to Landlord within thirty
(30) calendar days after the occurrence of such damage, in which event this
Lease shall be null and void. Such notice shall be effective ten (10) calendar
days after receipt by Landlord unless a later date is set forth in Tenant's
notice.

          4.10.3 Notwithstanding anything contained in this Lease to the
contrary, if there is damage to the Premises, or Building and the holder of any
indebtedness secured by a mortgage or deed of trust covering any such property
requires that the insurance proceeds be applied to such indebtedness, then
Landlord shall have the right to terminate this Lease by delivering written
notice of termination to Tenant within fifteen (15) calendar days after such
requirement is made by such holder.

     4.11 CONDEMNATION. If all of the Premises, or such portions of the Building
as may be required for the Tenant's reasonable use of the Premises, are taken by
eminent domain or by conveyance in lieu thereof, this Lease shall automatically
terminate as of the date the physical taking occurs, and all Base Rent,
Additional Rent and other sums payable under this Lease shall be paid to that
date. In case of taking of a part of the Premises or a portion of the Building
not required for the Tenant's reasonable use of the Premises, then this Lease
shall continue in full force and effect and the Base Rent shall be equitably
reduced based on the proportion by which the floor area of the Premises is
reduced, such reduction in Base Rent to be effective as of the date the physical
taking occurs. Additional Rent and all other sums payable under this Lease shall
be abated and Tenant's Pro Rata Share may be redetermined as equitable under the
circumstances. Landlord reserves all rights to damages or awards for any taking
by eminent domain relating to the Premises, Building, Land and the unexpired
term of this Lease. Tenant assigns to Landlord any right Tenant may have to such
damages or award and Tenant shall make no claim against Landlord for damages for
termination of its leasehold interest or interference with Tenant's business.
Tenant shall have the right, however, to claim and recover from the condemning
authority compensation for any loss to which Tenant may be entitled; provided
that, such expenses or costs may be claimed only if they are awarded separately
in the eminent domain proceedings.

against any and all third party Claims, arising in whole or in part out of (a)
the possession, use or occupancy of the Premises or the business conducted in
the Premises, (b) any act, omission or negligence of Tenant or Tenant's Agents,
or (c) any Event of Default under this Lease by Tenant. Except as expressly
provided to the contrary in the last sentence of this paragraph 4.13, neither

liability to Tenant, or to Tenant's Agents, for any Claims arising out of any
cause whatsoever, including repair to any portion of the Premises; interruption
in the use of the Premises or any equipment therein; any accident or damage
resulting from any use or operation by Landlord, Tenant or any person or entity

paragraph captioned "Maintenance and Repair by Landlord" provided that, in no
event shall Landlord be responsible for any interruption to Tenant's business or

keep and maintain in full force and effect:

          (a) A policy of commercial general liability insurance, including a
contractual liability endorsement covering Tenant's obligations under the
paragraph captioned "Indemnification", insuring against claims of bodily injury
and death or property damage or loss with a combined single limit at the
Commencement Date of this Lease of not less than Two Million Dollars
($2,000,000.00), which limit shall be reasonably increased during the Lease Term
at Landlord's request to reflect both increases in liability exposure arising
from inflation as well as from changing use of the Premises or changing legal
liability standards, which policy shall be payable on an "occurrence" rather
than a "claims made" basis, and which policy names Landlord and Manager and, at
Landlord's request Landlord's mortgage lender(s) or investment advisors, as
additional insureds; and

          (b) A policy of extended property insurance (which is commonly called
"all risk") covering overstandard Tenant Improvements, Tenant Alterations, and
any and all furniture, fixtures, equipment, inventory, improvements and other
property in or about the Premises which is not owned by Landlord, for one
hundred percent (100%) of the then current replacement value of such property.

                                      -19-
<PAGE>   24

          4.14.2 All insurance policies required under this paragraph shall be
with companies having a Best's rating of A-VIII or better, and each policy shall
provide that it is not subject to cancellation or reduction in coverage except
after thirty (30) calendar days' written notice to Landlord. Tenant shall
deliver to Landlord and, at Landlord's request Landlord's mortgage lender(s),
prior to the Commencement Date and from time to time thereafter, certificates
evidencing the existence and amounts of all such policies.

          4.14.3 If Tenant fails to acquire or maintain any insurance or provide
any certificate required by this paragraph, Landlord may, but shall not be
required to, obtain such insurance or certificates and the costs associated with
obtaining such insurance or certificates shall be payable by Tenant to Landlord
on demand.

     4.15 LANDLORD'S INSURANCE. Landlord shall, throughout the Lease Term, keep
and maintain in full force and effect:

          4.15.1 A policy of commercial general liability insurance, insuring
against claims of bodily injury and death or property damage or loss with a
combined single limit at the Commencement Date of not less than Five Million
Dollars ($5,000,000.00), which policy shall be payable on an "occurrence" rather
than a "claims made" basis; and

          4.15.2 A policy of extended property insurance (what is commonly
called "all risk") covering the Building, Tenant Improvements and Landlord's
personal property, if any, located on the Land in the amount of one hundred
percent (100%) of the then current replacement value of such property.

          Landlord may, but shall not be required to, maintain property
insurance coverage for earthquakes, floods and such other perils in such amounts
as Landlord deems appropriate. Such policies may be "blanket" policies which
cover other properties owned by Landlord and shall be with an insurance company
having a Best rating of A-VIII or better. The cost of all insurance policies
maintained by Landlord relating to the Land, Building or Premises or the income
derived from "loss of rent" insurance, as the case may be, shall be Operating
Costs. To the extent that any payment on an insurance claim under any Landlord's
policy is reduced by a deductible, such deductible shall be an Operating Cost.

     4.16 WAIVER OF SUBROGATION. Notwithstanding anything in this Lease to the
contrary, Landlord and Tenant hereby each waive and release the other from any
and all Claims or any loss or damage that may occur to the Land, Building,
Premises, or personal property located therein, by reason of fire or other
casualty regardless of cause or origin, including the negligence or misconduct
of Landlord, Tenant, Landlord's Agents or Tenant's Agents, but only to the
extent of the insurance proceeds paid to such releasor under its policies of
insurance or if it fails to maintain the required policies, the insurance
proceeds that would have been paid to such releasor if it had maintained such
policies. Each party to this Lease shall promptly give to its insurance company
written notice of the mutual waivers contained in this subparagraph, and shall
cause its insurance policies to be properly endorsed, if necessary, to prevent
the invalidation of any insurance coverages by reason of the mutual waivers
contained in this subparagraph.

      4.17 ASSIGNMENT AND SUBLETTING BY TENANT.

            4.17.1 Except for a sublease of all or a portion of the Premises or
an assignment of this Lease to (i) the survivor of a merger or consolidation
with Tenant, (ii) any entity acquiring all or substantially all of the voting
securities or assets of Tenant or (iii) an affiliate or wholly-owned subsidiary
of Tenant, which sublease or assignment shall be permitted hereunder and shall
not require Landlord's consent (provided that Tenant shall give Landlord prior
written notice, and a true and correct copy, of the sublease or assignment
document), and which sublease or assignment shall be subject to further
prohibitions against sublease or assignment in accordance with the terms of this
Section 4.17, Tenant shall not have the right to assign, transfer, mortgage or
encumber this Lease in whole or in part, nor sublet the whole or any part of the
Premises, nor allow the occupancy of all or any part of the Premises by another,
without first obtaining Landlord's consent, which shall not be unreasonably,
withheld or delayed but may be granted or withheld in accordance with the
provisions set forth in Section 4.17.3 hereof. Notwithstanding any permitted
assignment or subletting, Tenant shall at all times remain directly, primarily
and fully responsible and liable for the payment of all sums payable under this
Lease and for compliance with all of its other obligations as tenant under this
Lease. Upon the occurrence of an Event of Default, if the Premises or any part
of the Premises are then subject to an assignment or subletting, Landlord, in
addition to any other remedies provided in this Lease or by law, may at its
option collect directly from such assignee or subtenant all rents becoming due
to Tenant under such assignment or sublease and apply such rents against any
sums due to Landlord from Tenant under this Lease, and no such collection shall
be construed to constitute a novation or release of Tenant from the further
performance of Tenant's obligations under this Lease. Upon the occurrence of an
Event of Default, Tenant hereby makes an absolute assignment to Landlord of such
assignments and subleases and any rent, security deposits and other sums payable
under such assignments and subleases as collateral to secure the performance of
the obligations of Tenant under this Lease.

            4.17.2 In the event Tenant desires to assign this Lease or to sublet
all or any portion of the Premises, except in the circumstances set forth herein
where consent is not required as contemplated and governed by paragraph 4.17.1,
Tenant shall give written notice of such desire to Landlord setting forth the
name of the proposed subtenant or assignee, the proposed term, the proposed
commencement date of the assignment or sublease, the nature of the proposed
subtenant's or assignee's business to be conducted on the Premises, the rental
rate, and any other particulars of the proposed subletting or assignment that
Landlord may reasonably request. Without limiting the preceding sentence, Tenant
shall also provide Landlord with: (a) such financial information as Landlord may
reasonably request concerning the proposed subtenant or assignee, including
recent financial statements certified as accurate, complete and prepared in
conformance with generally accepted accounting principles by the president,
managing partner or other appropriate officer of the proposed subtenant or
assignee; (b) proof reasonably satisfactory to Landlord that the proposed
subtenant or assignee will promptly occupy and thereafter use the entire
Premises (or any sublet portion of the Premises) for the remainder of the Lease
Term (or for the entire term of the sublease, if shorter) in compliance with the
terms of this Lease, and (c) a copy of the proposed sublease or assignment or
letter of intent. At the same time that Tenant provides Landlord with notice of
its desire to assign or sublease, Tenant shall pay to Landlord the reasonable
cost incurred by Landlord (not to exceed the sum of $750) in connection with
processing such proposed assignment and sublease, including attorneys' fees
incurred by Landlord with respect to such processing. Receipt of such fee shall
not obligate Landlord to approve the proposed assignment or sublease.

<PAGE>   26
            4.17.3 In determining whether to grant or withhold consent to a
proposed assignment or sublease, Landlord may consider, and weigh, any
commercially reasonable factor it deems relevant. Without limiting what may be
construed as a factor considered by Landlord in good faith, Tenant agrees that
any one or more of the following will be proper grounds for Landlord's
disapproval of a proposed assignment or sublease:

            (a) The proposed assignee or subtenant is or will be unwilling or
unable to execute and deliver to Landlord an ERISA Certificate in a form
consistent with the provisions of the paragraph captioned "ERISA
Representations", as may be updated by Landlord, or Landlord believes that the
proposed assignment or sublease will constitute a prohibited transaction under
or otherwise violate ERISA;

            (b) The proposed assignee or subtenant does not, in Landlord's good
faith judgment, have sufficient financial worth to insure the full and timely
performance under this Lease;

            (c) Landlord has received insufficient evidence of the financial
worth or creditworthiness of the proposed assignee or subtenant to make the
determination set forth in clause (b);

            (d) The proposed assignee or subtenant has a reputation for disputes
in contractual relations, for failure to observe and perform its contractual
obligations in a timely and complete manner or for negative business relations
in the business community as a tenant of property or otherwise;

            (e) Landlord has received from any prior lessor of the proposed
assignee or subtenant a negative report, in writing concerning such prior
lessor's experience with the proposed assignee or subtenant;

            (f) Landlord has had prior negative leasing experience with the
proposed assignee or subtenant;

            (g) The use of the Premises by the proposed assignee or subtenant
will not be substantially similar to the Permitted Use;

            (h) In Landlord's reasonable judgment the proposed assignee or
subtenant is engaged in a business, or the Premises or any part of the Premises
will be used in a manner, that is not in keeping with the then standards of the
Building, or that is inappropriate for the Building, or that will violate any
negative covenant as to use contained in any other lease of space in the
Building;

            (i) The use of the Premises by the proposed assignee or subtenant
will violate any Governmental Requirement or create a violation of Access Laws;
or

            (j) An Event of Default (after expiration of any cure period) by
Tenant under this Lease has occurred and is then continuing, or an Event of
Default (after expiration of any cure period) by Tenant under this Lease has
occurred on three (3) or more occasions during the twenty-four (24) months
preceding the date that Tenant shall request such consent.

            4.17.4 Within fifteen (15) calendar days after Landlord's receipt of
all required information to be supplied by Tenant pursuant to this paragraph,
Landlord shall notify Tenant of Landlord's approval, disapproval or conditional
approval of any proposed assignment or subletting, or of Landlord's

                                      -22-
<PAGE>   27
election to recapture the space as provided in subparagraph 4.17.7. Landlord
shall have no obligation to respond unless and until all required information
has been submitted. In the event Landlord approves of any proposed assignment or
subletting, Tenant and the proposed assignee or sublessee shall execute and
deliver to Landlord an assignment (or subletting) and assumption agreement in
form and content satisfactory to Landlord.

            4.17.5 If Landlord consents to any assignment or sublease and Tenant
receives rent or any other consideration, either initially or over the term of
the assignment or sublease, in excess of the Base Rent and Additional Rent,
Tenant shall pay to Landlord, after deducting Tenant's reasonable out-of-pocket
costs incurred in connection with such assignment or sublease, one-half of the
excess rent or other consideration derived therefrom.

            4.17.6 If Tenant delivers a notice to Landlord requesting approval
of a proposed assignment or sublease, then Landlord may elect to terminate this
Lease as of the date set forth in that notice, with respect to that portion of
the Premises covered by the proposed assignment or sublet, for the proposed
commencement date of the assignment or the sublease, provided that, if no date
is set forth in Tenant's notice, then Landlord may elect to terminate this Lease
as of a date at least sixty (60) calendar days after the date of the notice.
Landlord shall exercise its rights under this subparagraph by written notice to
Tenant no later than fifteen (15) calendar days after its receipt of the last of
the materials delivered by Tenant to Landlord under this paragraph 4.17.

      4.18 ASSIGNMENT BY LANDLORD. Landlord shall have the right to transfer and
assign, in whole or in part, its rights and obligations under this Lease and in
any and all of the Land or Building. If Landlord sells or transfers any or all
of the Building, including the Premises, Landlord and Landlord's Agents shall,
upon consummation of such sale or transfer, be released automatically from any
liability relating to obligations or covenants under this Lease to be performed
or observed after the date of such transfer (provided and to the extent the
transferee or purchaser assumes such obligations and covenants to be performed
or observed after the date of such transfer), and in such event, Tenant agrees
to look solely to Landlord's successor-in-interest with respect to such
liability; provided that, as to the Security Deposit, if any, and Prepaid Rent,
Landlord shall not be released from liability therefor unless Landlord has
delivered (by direct transfer or credit against the purchase price) the Security
Deposit, if any, or Prepaid Rent to its successor-in-interest.

      4.19 ESTOPPEL CERTIFICATES AND FINANCIAL STATEMENTS. Tenant shall, from

Additional Rent and the date to which such Base Rent and Additional Rent have

specifying the date of the agreement so affecting this Lease); (2) Landlord is

it is intended that any Tenant's statement may be relied upon by a prospective
purchaser or mortgagee of Landlord's interest or an assignee of any such
mortgagee; (9) the representations in the paragraph captioned "ERISA
Representations" remain true and correct; and (10) such other information as may
be reasonably requested by Landlord. If Tenant fails to respond within ten (10)

to have admitted the accuracy of any information supplied by Landlord to a
prospective purchaser, mortgagee or assignee. In addition, Tenant shall, from
time to time, upon the written request of Landlord, deliver to or cause to be
delivered to Landlord or its designee then current financial statements

construction, interim or permanent financing for the Building or Land,
Landlord's lender, if any, shall request reasonable modifications to this Lease
as a condition to such financing. Tenant will not unreasonably withhold or delay
its consent to such modifications; provided that such modifications do not
increase the obligations of Tenant under this Lease or adversely affect Tenant's
rights under this Lease.

      4.21 HAZARDOUS SUBSTANCES.

            4.21.1 Tenant agrees that neither Tenant, any of Tenant's Agents nor
any other person acting at the direction or being under the control of Tenant or
any of Tenant's Agents will store, place, generate, manufacture, refine, handle,
or locate on, in, under or around the Land or Building any Hazardous Substance,
except for storage, handling and use of reasonable quantities and types of
cleaning fluids and office supplies in the Premises in the ordinary course and
the prudent conduct of Tenant's business in the Premises, provided that, (a) the
storage, handling and use of such permitted Hazardous Substances must at all
times conform to all Governmental Requirements and to applicable fire, safety
and insurance requirements; (b) the types and quantities of permitted Hazardous
Substances which are stored in the Premises must be reasonable and appropriate
to the nature and size of Tenant's operation in the Premises and reasonable and
appropriate for a first-class building of the same or similar use and in the
same market area as the Building; (c) no Hazardous Substance shall be spilled or
disposed of on, in, under or around the Land or Building or otherwise discharged
from the Premises or any area adjacent to the Land or Building; and (d) in no
event will Tenant be permitted to store, handle or use on, in, under or around
the Premises any Hazardous Substance which will increase the rate of fire or
extended coverage insurance on the Land or Building, unless: (1) such Hazardous
Substance and the expected rate increase have been specifically disclosed in
writing to Landlord; (2) Tenant has agreed in writing to pay any rate increase
related to each such Hazardous Substance; and (3) Landlord has approved in
writing each such Hazardous Substance, which approval shall be subject to
Landlord's sole discretion.

            4.21.2 Tenant shall indemnify, defend and hold harmless Landlord and
Landlord's Agents from and against any and all Claims arising out of any breach
of any provision of this paragraph, which expenses shall also include laboratory
testing fees, personal injury claims, clean-up costs and environmental
consultants' fees. Tenant agrees that Landlord may be irreparably harmed by
Tenant's breach of this paragraph and that a specific performance action may
appropriately be brought by Landlord; provided that,

                                      -24-
<PAGE>   29
Landlord's election to bring or not bring any such specific performance action
shall in no way limit, waive, impair or hinder Landlord's other remedies against
Tenant.

            4.21.3 As of the execution date of this Lease, Tenant represents and
warrants to Landlord that, except as otherwise disclosed by Tenant to Landlord,
Tenant has no intent to bring any Hazardous Substances on, in or under the

            4.21.4 Landlord represents and warrants to Tenant that, to the best
of its knowledge, no Hazardous Substances exist at the Building or the Land in
violation of any Governmental Requirements pertaining to Hazardous Substances.
Landlord shall indemnify, defend and hold harmless Tenant from and against any
and all Claims incurred by Tenant arising out of or in connection with Landlord
or Landlord's Agents bringing any Hazardous Substances onto the Land or Building
in violation of Governmental Requirements.

      4.22 ACCESS LAWS.

            4.22.1 Tenant agrees to notify Landlord immediately if Tenant
receives notification or otherwise becomes aware of: (a) any condition or
situation on, in, under or around the Land or Building which may constitute a
violation of any Access Laws or (b) any threatened or actual lien, action or
notice that the Land or Building is not in compliance with any Access Laws. If
Tenant is responsible for such condition, situation, lien, action or notice
under this paragraph. Tenant's notice to Landlord shall include a statement as
to the actions Tenant proposes to take in response to such condition, situation,
lien, action or notice.

            4.22.2 Tenant shall not alter or permit any assignee or subtenant or
any other person to alter the Premises in any manner which would violate any
Access Laws or increase Landlord's responsibilities for compliance with Access
Laws, without the prior approval of the Landlord. In connection with any such
approval, Landlord may require a certificate of compliance with Access Laws from
an architect, engineer or other person acceptable to Landlord. Tenant agrees to
pay the reasonable fees incurred by such architect, engineer or other third
party in connection with the issuance of such certificate of compliance.
Landlord's consent to any proposed Tenant Alteration shall (a) not relieve
Tenant of its obligations or indemnities contained in this paragraph or this
Lease or (b) be construed as a warranty that such proposed alteration complies
with any Access Law.

            4.22.3 Tenant shall be solely responsible for all costs and expenses
relating to or incurred in connection with: (a) failure of Tenant's use of the
Premises to comply with Access Laws; and (b) bringing the Building and the
common areas of the Building into compliance with Access Laws, if and to the
extent such failure or noncompliance arises out of or relates to: (1) Tenant's
use of the Premises in violation of this Lease; or (2) Tenant Alterations to the
Premises.

            4.22.4 Landlord shall be responsible for all costs and expenses
relating to or incurred in connection with bringing the common areas of the
Building into compliance with Access Laws, unless such costs and expenses are
Tenant's responsibility as provided in the preceding subparagraph. Any cost or
expense paid or incurred by Landlord after initial construction to bring the
Premises or common areas of the Building into compliance with Access Laws which
is not Tenant's responsibility under the preceding subparagraphs and which is
not required as a result of Landlord's negligence (which shall be Landlord's

                                      -25-
<PAGE>   30
sole expense), shall be amortized over the useful economic life of the
improvements using an amortization rate reasonably determined by Landlord, and
shall be an Operating Cost for purposes of this Lease.

            4.22.5 Tenant agrees to indemnify, defend and hold harmless Landlord
and Landlord's Agents from and against any and all Claims arising out of or
relating to any failure of Tenant or Tenant's Agents to comply with Tenant's
obligations under this paragraph 4.22. Landlord agrees to indemnify, defend and
hold harmless Tenant and Tenant's Agents from and against any and all Claims
arising out of or relating to any failure of Landlord or Landlord's Agents to
comply with Landlord's obligations under this paragraph 4.22.

            4.22.6 The provisions of this paragraph shall supersede any other
provisions in this Lease regarding Access Laws, to the extent inconsistent with
the provisions of any other paragraphs.

      4.23 QUIET ENJOYMENT. Landlord covenants that Tenant, upon paying Base
Rent, Additional Rent and all other sums payable under this Lease and performing
all covenants and conditions required of Tenant under this Lease shall and may
peacefully have, hold and enjoy the Premises without hindrance or molestation
by Landlord or Landlord's Agents.

      4.24 SIGNS. Tenant shall not install any signs on the Building exterior
or inscribe, post, place, or in any manner display any sign, notice, picture,
placard or poster, or any advertising matter whatsoever, anywhere in or about
the Land or Building (including without limitation the interior of the Premises)
at places visible (either directly or indirectly as an outline or shadow on a
glass pane) from anywhere outside the Premises without first obtaining
Landlord's consent, which shall not be unreasonably withheld. Notwithstanding
the foregoing, Landlord shall provide to Tenant, at Landlord's expense, standard
identification signage on the main directory in the lobby of the Building.

      4.25 SUBORDINATION. Tenant subordinates this Lease and all rights of
Tenant under this Lease to any mortgage, deed of trust, ground lease or similar
instrument which may from time to time be placed upon the Premises (and all
renewals, modifications, replacements and extensions of such encumbrances), and
each such mortgage, deed of trust, ground lease or other instrument shall be
superior to and prior to this Lease. Notwithstanding the foregoing, the holder
or beneficiary of such mortgage, deed of trust, ground lease, or similar
instrument shall have the right to subordinate or cause to be subordinated any
such mortgage, deed of trust, ground lease, or similar instrument to this Lease.
Tenant further covenants and agrees that if the lender or ground lessor acquires
the Premises as a purchaser at any foreclosure sale or otherwise, Tenant shall
recognize and attorn to such party as landlord under this Lease, and shall make
all payments required hereunder to such new landlord without deduction or
set-off and, upon the request of such purchaser or other successor, execute,
deliver and acknowledge documents confirming such attornment. Tenant waives the
provisions of any law or regulation, now or hereafter in effect, which may give
or purport to give Tenant any right to terminate or otherwise adversely affect
this Lease or the obligations of Tenant hereunder in the event that any such
foreclosure or termination or other proceeding is prosecuted or completed.
Notwithstanding the foregoing to the contrary, Landlord shall use best efforts
to deliver to Tenant a non-disturbance agreement, in reasonable and customary
form and substance, from any lender or ground lessor, whether now existing or in
the future. Landlord represents and warrants to Tenant that, as of the date of
this Lease, there is no mortgage recorded against the Building.

      4.26 INTENTIONALLY OMITTED.

      4.27 BROKERS. Landlord covenants and agrees to pay the Brokers with
respect to this Lease pursuant to separate agreements with the Brokers. Each
party to this Lease shall indemnify, defend and hold harmless the other party
from and against any and all Claims asserted against such other party by any
real estate broker, finder or intermediary relating to any act of the
indemnifying party in connection with this Lease.

      4.28 EXCULPATION AND LIMITATION OF LIABILITY. Landlord has executed this
Lease by its trustee signing solely in a representative capacity.
Notwithstanding anything contained in this Lease to the contrary, Tenant
confirms that the covenants of Landlord are made and intended, not as personal
covenants of the trustee, or for the purpose of binding the trustee personally,
but solely in the exercise of the representative powers conferred upon the
trustee by its principal. Liability with respect to the entry and performance of
this Lease by or on behalf of Landlord, however it may arise, shall be asserted
and enforced only against the Landlord's estate and interest in the Building and
Landlord shall have no personal liability in the event of any claim against
Landlord arising out of or in connection with this Lease, the relationship of
Landlord and Tenant or Tenant's use of the Premises. Further, in no event
whatsoever shall any Landlord's Agent have any liability or responsibility
whatsoever arising out of or in connection with this Lease, the relationship of
Landlord and Tenant or Tenant's use of the Premises. Any and all personal
liability, if any, beyond that which may be asserted under this paragraph, is
expressly waived and released by Tenant and by all persons claiming by, through
or under Tenant.

      4.29 ERISA REPRESENTATIONS. Tenant represents to Landlord that with the

or more of the entities named in clauses (1) (a) through (e) are known by the
Tenant to have an ownership interest.

      4.30 MECHANIC'S LIENS AND TENANT'S PERSONAL PROPERTY TAXES.

            4.30.1 Tenant shall have no authority, express or implied, to create
or place any lien or encumbrance of any kind or nature whatsoever upon, or in
any manner to bind, the interest of Landlord or Tenant in the Premises or to
charge the rentals payable under this Lease for any Claims in favor of any
person dealing with Tenant, including those who may furnish materials or perform
labor for any construction or repairs. Tenant shall pay or cause to be paid all
sums legally due and payable by it on account of any labor performed or
materials furnished in connection with any work performed on the Premises on
which any lien is or can be validly and legally asserted against its leasehold
interest in the Premises and Tenant shall indemnify, defend and hold harmless
Landlord from any and all Claims arising out of any such asserted Claims.
Tenant agrees to give Landlord immediate written notice of any such Claim.
Notwithstanding the foregoing to the contrary, Tenant may pay any materialmen or
other lien

                                      -27-
<PAGE>   32
claimant under protest in satisfaction of this paragraph, without being deemed
to have waived any rights Tenant may have at law or equity against such
materialmen or lien claimant.

            4.30.2 Tenant shall be liable for all taxes levied or assessed
against personal property, furniture or fixtures placed by Tenant in the
Premises. If any such taxes for which Tenant is liable are levied or assessed
against Landlord or Landlord's property and Landlord elects to pay them or if
the assessed value of Landlord's property is increased by inclusion of such
personal property, furniture or fixtures and Landlord elects to pay the taxes
based on such increase, Tenant shall reimburse Landlord for the sums so paid by
Landlord, upon demand by Landlord.

         4.31 LANDLORD'S SECURITY INTEREST. In addition to any statutory lien
for rent in Landlord's favor, Landlord shall have and Tenant hereby grants to
Landlord a continuing security interest for all Base Rent, Additional Rent and
other sums becoming due under this Lease from Tenant, upon all goods, wares,
equipment, fixtures, furniture, inventory, accounts, intangibles, chattel paper
and other personal property of Tenant situated in or arising out of the
Premises, and such property shall not be removed therefrom without the consent
of Landlord until all arrearages in Base Rent, Additional Rent and other sums
due under this Lease shall first have been paid and discharged. On the
occurrence of an Event of Default, Landlord shall have, in addition to any other
remedies provided herein or by law, all rights and remedies under the Uniform
Commercial Code, including, the right to sell the property described in this
paragraph at public or private sale upon five (5) calendar days notice to
Tenant. Tenant hereby agrees to execute such financing statements and other
instruments necessary or desirable in Landlord's discretion to perfect the
security interest hereby created. Any statutory lien for rent is not waived, and
the express contractual lien granted in this paragraph constitutes a security
agreement and is in addition and supplementary to such statutory lien.

                         SECTION 5: DEFAULT AND REMEDIES

      5.1 EVENTS OF DEFAULT.

            5.1.1 The occurrence of any one or more of the following events
shall constitute a material default and breach of this Lease by Tenant ("EVENT
OF DEFAULT"):

            (a)   vacation or abandonment of the Premises, together with the
failure to pay Base Rent, Additional Rent or any other sum payable by Tenant
under this Lease in accordance with the provisions governing the payment
thereof;

            (b)   failure by Tenant to make any payment of Base Rent, Additional
Rent or any other sum payable by Tenant under this Lease after it is past due
and within five (5) days of written notice thereof;

            (c)   an assignment of this Lease by Tenant or a sublease of any or
all of the Premises without Landlord's permission;

            (d)   failure by Tenant to observe or perform any covenant or
condition of this Lease, other than the making of payments, where such failure
shall continue for a period of thirty (30) calendar days after written notice
from Landlord, and provided that if such failure requires more than 30 days to

                                      -28-
<PAGE>   33
cure, Tenant shall have such additional time as is necessary to cure such
failure so long as Tenant has promptly commenced to cure and diligently pursues
such cure to completion; provided that in no event shall such cure period extend
beyond ninety (90) days;

            (e) (1) the making by Tenant of any general assignment or general
arrangement for the benefit of creditors; (2) the filing by or against Tenant of
a petition in bankruptcy, including reorganization or arrangement, unless, in
the case of a petition filed against Tenant, the same is dismissed within
forty-five (45) calendar days; (3) the appointment of a trustee or receiver to
take possession of substantially all of Tenant's assets located in the Premises
or of Tenant's interest in this Lease; (4) any execution, levy, attachment or

fraud of creditors; or (7) the failure of Tenant to generally pay its debts as
they become due; or

            (f) any information furnished by or on behalf of Tenant to Landlord
in connection with the entry of this Lease is determined to have been materially
false when made.

            5.1.2 Tenant shall notify Landlord promptly of any Event of Default
or any facts, conditions or events which, with the giving of notice or passage
of time or both, would constitute an Event of Default.

            5.1.3 If a petition in bankruptcy is filed by or against Tenant, and
if this Lease is treated as an "unexpired lease" under applicable bankruptcy law
in such proceeding, then Tenant agrees that Tenant shall not attempt nor cause
any trustee to attempt to extend the applicable time period within which this
Lease must be assumed or rejected.

      5.2 REMEDIES. If any Event of Default occurs, Landlord may at any time
after such occurrence, with notice and the expiration of the cure period as
provided in paragraph 5.1.1 of this Lease, and without limiting Landlord in the
exercise of any right or remedy at law which Landlord may have by reason of
such Event of Default, exercise the rights and remedies, either singularly or in
combination, as are specified or described in the subparagraphs of this
paragraph.

            5.2.1 Landlord may terminate this Lease and all rights of Tenant
under this Lease either immediately or at some later date by giving Tenant
written notice that this Lease is terminated. If Landlord so terminates this
Lease, then Landlord may recover from Tenant the sum of:

            (a)   the unpaid Base Rent, Additional Rent and all other sums
payable under this Lease which have been earned at the time of termination;

            (b)   interest at the Default Rate on the unpaid Base Rent,
Additional Rent and all other sums payable under this Lease which have been
earned at the time of termination; plus

            (c)   the amount by which the unpaid Base Rent, Additional Rent and
all other sums payable under this Lease which would have been earned after
termination until the time of award exceeds the amount of such rental loss, if
any, as Tenant affirmatively proves could have been reasonably avoided and
interest on such excess at the Default Rate; plus

                                      -29-
<PAGE>   34
            (d)   the amount by which the aggregate of the unpaid Base Rent,
Additional Rent and all other sums payable under this Lease for the balance of
the Lease Term after the time of award exceeds the amount of such rental loss,
if any, as Tenant affirmatively proves could be reasonably avoided, with such
difference being discounted to present value at the Prime Rate at the time of
award; plus

            (e)   any other amount necessary to compensate Landlord for the
detriment proximately caused by Tenant's failure to perform Tenant's obligations
under this Lease or which, in the ordinary course of things, would be likely to
result from such failure, including, leasing commissions, tenant improvement
costs, renovation costs and advertising costs; plus

            (f)   all such other amounts in addition to or in lieu of the
foregoing as may be permitted from time to time by applicable law.

            5.2.2 Landlord shall also have the right, with or without
terminating this Lease, to re-enter the Premises and remove all persons and
property from the Premises. Landlord may cause property so removed from the
Premises to be stored in a public warehouse or elsewhere at the expense and for
the account of Tenant.

            5.2.3 Landlord shall also have the right, without terminating this
Lease, to accelerate and recover from Tenant the sum of all unpaid Base Rent,
Additional Rent and all other sums payable under the then remaining term of the
Lease, discounting such amount to present value at the Prime Rate.

            5.2.4 If Tenant vacates, abandons or surrenders the Premises without
Landlord's consent, or if Landlord re-enters the Premises as provided in
subparagraph 5.2.2 or takes possession of the Premises pursuant to legal
proceedings or through any notice procedure provided by law, then, if Landlord
does not elect to terminate this Lease, Landlord may, from time to time, without
terminating this Lease, either (a) recover all Base Rent, Additional Rent and
all other sums payable under this Lease as they become due or (b) relet the
Premises or any part of the Premises on behalf of Tenant for such term or terms,
at such rent or rents and pursuant to such other provisions as Landlord, in its
reasonable discretion, may deem commercially reasonable, all with the right, at
Tenant's cost, to make reasonably necessary alterations and repairs to the
Premises and recover any deficiency from Tenant as set forth in subparagraph
5.2.5.

            5.2.5 None of the following remedial actions, singly or in
combination, shall be construed as an election by Landlord to terminate this
Lease unless Landlord has in fact given Tenant written notice that this Lease is
terminated: an act by Landlord to maintain or preserve the Premises; any efforts
by Landlord to relet the Premises; any repairs or alterations made by Landlord
to the Premises; re-entry, repossession or reletting of the Premises by Landlord
pursuant to this paragraph; or the appointment of a receiver, upon the
initiative of Landlord, to protect Landlord's interest under this Lease. If
Landlord takes any of the foregoing remedial action without terminating this
Lease, Landlord may nevertheless at any time after taking any such remedial
action terminate this Lease by written notice to Tenant.

            5.2.6 If Landlord relets the Premises, Landlord shall apply the
revenue from such reletting as follows: first, to the payment of any
indebtedness of Tenant to Landlord other than Base Rent, Additional Rent or any
other sums payable by Tenant under this Lease; second, to the payment of any
cost of reletting (including finders' fees and leasing commissions limited to
the then remaining term of this Lease); third, to the payment of the cost of any
reasonably necessary alterations, improvements, maintenance and repairs to the
Premises; and fourth, to the payment of Base Rent, Additional Rent and

                                      -30-

<PAGE>   35
other sums due and payable and unpaid under this Lease. Landlord shall hold and
apply the residue, if any, to payment of future Base Rent, Additional Rent and
other sums payable under this Lease as the same become due, and shall deliver
the eventual balance, if any, to Tenant. Should revenue from letting during any
month, after application pursuant to the foregoing provisions, be less than the
sum of the Base Rent, Additional Rent and other sums payable under this Lease
and Landlord's expenditures for the Premises during such month, Tenant shall be
obligated to pay such deficiency to Landlord as and when such deficiency arises.

            5.2.7 Pursuit of any of the foregoing remedies shall not preclude
pursuit of any of the other remedies provided in this Lease or by law (all such
remedies being cumulative), nor shall pursuit of any remedy provided in this
Lease constitute a forfeiture or waiver of any Base Rent, Additional Rent or
other sum payable under this Lease or of any damages accruing to Landlord by
reason of the violation of any of the covenants or conditions contained in this
Lease.

            5.2.8 Notwithstanding anything contained in this Lease to the
contrary, Landlord shall use reasonable efforts to mitigate its damages upon the
occurrence of an Event of Default by Tenant under this Lease.

      5.3 RIGHT TO PERFORM. If Tenant shall fail to perform any act on its part
to be performed under this Lease, and such failure shall continue for thirty
(30) calendar days after notice of such failure by Landlord, or such shorter
time if reasonable under the circumstances, Landlord may, but shall not be
obligated to, and without waiving or releasing Tenant from any obligations of
Tenant, make such payment or perform such other act on Tenant's part to be made
or performed as provided in this Lease. Landlord shall have (in addition to any
other right or remedy of Landlord) the same rights and remedies in the event of
the nonpayment of sums due under this paragraph as in the case of default by
Tenant in the payment of Base Rent.

      5.4 LANDLORD'S DEFAULT. In the event that Landlord defaults under or
breaches this Lease, Tenant shall notify Landlord of such default or breach in
writing, and Tenant shall not exercise any right or remedy which Tenant may have
under this Lease or at law if Landlord commences to cure such default or breach
within thirty (30) calendar days after receipt of Tenant's notice and thereafter
diligently prosecutes the cure to completion.

                      SECTION 6: MISCELLANEOUS PROVISIONS

      6.1 NOTICES. Any notice, request or written communication required or
permitted to be delivered under this Lease shall be: (a) in writing; (b)
transmitted by personal delivery, express or courier service, United States
Postal Service in the manner described below, or electronic means of
transmitting written material; and (c) deemed to be delivered on the earlier of
the date received or four (4) calendar days after having been deposited in the
United States Postal Service, postage prepaid. Such writings shall be addressed
to Landlord or Tenant, as the case may be, at the respective designated
addresses set forth opposite their signatures, or at such other address(es) as
they may, after the execution date of this Lease, specify by written notice
delivered in accordance with this paragraph, with copies to the persons at the
addresses, if any, designated opposite each party's signature. Those notices
which contain a notice of breach or default or a demand for performance may be

above, but if transmitted by personal delivery or electronic means, shall also
be sent concurrently by certified or registered mail, return receipt requested.

      6.2 ATTORNEY'S FEES AND EXPENSES. In the event either party requires the
services of an attorney in connection with enforcing the terms of this Lease, or
in the event suit is brought for the recovery of Base Rent, Additional Rent or
any other sums paid or payable under this Lease or for the breach of any
covenant or condition of this Lease, or for the restitution of the Premises to
Landlord or the eviction of Tenant during the Lease Term or after the expiration
or earlier termination of this Lease, the prevailing party shall be entitled to
its reasonable attorney's and paralegal's fees, expenses and court costs,
including those relating to any appeal.

      6.3 NO ACCORD AND SATISFACTION. No payment by Tenant or receipt by
Landlord of an amount less than the Base Rent or Additional Rent or any other
sum due and payable under this Lease shall be deemed to be other than a payment
on account of the Base Rent, Additional Rent or other such sum, nor shall any
endorsement or statement on any check or any letter accompanying any check or
payment be deemed an accord and satisfaction, nor preclude Landlord's right to
recover the balance of any amount payable or Landlord's right to pursue any
other remedy provided in this Lease or at law.

      6.4 SUCCESSORS; JOINT AND SEVERAL LIABILITY. Except as provided in the
paragraph captioned "Exculpation and Limitation of Liability" and subject to the
paragraph captioned "Assignment and Subletting by Landlord", all of the
covenants and conditions contained in this Lease shall apply to and be binding
upon Landlord and Tenant and their respective heirs, executors, administrators,
successors and assigns. In the event that more than one person, partnership,
company, corporation or other entity is included in the term "Tenant," then each
such person, partnership, company, corporation or other entity shall be jointly
and severally liable for all obligations of Tenant under this Lease.

      6.5 CHOICE OF LAW. This Lease shall be construed and governed by the laws
of the state in which the Land is located. Tenant consents to Landlord's choice
of venue for any legal proceeding brought by Landlord or Tenant to enforce the
terms of this Lease.

      6.6 NO WAIVER OF REMEDIES. The waiver by Landlord or Tenant of any
covenant or condition contained in this Lease shall not be deemed to be a waiver
of any subsequent breach of such covenant or condition nor shall any custom or
practice which may develop between the parties in the administration of this
Lease be construed to waive or lessen the rights of Landlord or Tenant to insist
on the strict performance by the other party of all of the covenants and
conditions of this Lease. No act or thing done by Landlord or Landlord's Agents
during the Lease Term shall be deemed an acceptance or a surrender of the
Premises, and no agreement to accept a surrender of the Premises shall be valid
unless made in writing and signed by Landlord. The mention in this Lease of any
particular remedy shall not preclude Landlord or Tenant from any other remedy it
might have, either under this Lease or at law, nor shall the waiver of or
redress for any violation of any covenant or condition in this Lease or in any
of the rules or regulations attached to this Lease or later adopted by Landlord,
prevent a subsequent act, which would have originally constituted a violation,
from having all the force and effect of an original violation. The receipt by
Landlord of Base Rent, Additional Rent or any other sum payable under this Lease
with knowledge of a breach of any covenant or condition in this Lease shall not
be deemed a waiver of such breach. The payment by Tenant of any sum or amount
due or payable under this Lease may be made under protest and shall not be
deemed a waiver of any breach or default by Landlord under this Lease. The
failure of Landlord to enforce any of the rules and regulations attached to this
Lease or later adopted,

                                      -32-
<PAGE>   37
against Tenant or any other tenant in the Building, shall not be deemed a
waiver. Any waiver by Landlord must be in writing and signed by Landlord to be
effective.

      6.7 OFFER TO LEASE. The submission of this Lease to Tenant or its broker
or other agent does not constitute an offer to Tenant to lease the Premises.
This Lease shall have no force or effect until: (a) it is executed and delivered
by Tenant to Landlord; and (b) it is executed and delivered by Landlord to
Tenant.

      6.8 FORCE MAJEURE. In the event that Landlord shall be delayed, hindered
in or prevented from the performance of any act or obligation required under
this Lease by reason of Force Majeure, then performance of such act or
obligation shall be excused for the period of the delay and the period for the
performance of any such act or obligation shall be extended for the period
equivalent to the period of such delay.

      6.9 LANDLORD'S CONSENT. Unless otherwise provided in this Lease, whenever
Landlord's consent, approval or other action is required under the terms of this
Lease, such consent, approval or action shall be subject to Landlord's
reasonable judgment or discretion, not unreasonably withheld, exercised in good
faith and shall be delivered in writing.

      6.10 SEVERABILITY; CAPTIONS. If any clause or provision of this Lease is

invalid or unenforceable, there be added as a part of this Lease a clause or
provision as similar in terms to such illegal, invalid or unenforceable clause

agreement, term or provision, (c) "at law", that term shall mean at law or in
equity, or both, and (d) "day", that uncapitalized word shall mean a calendar
day. This Lease shall be given a fair and reasonable interpretation of the words
contained in it without any weight being given to whether a provision was
drafted by one party or its counsel. For purposes of this Lease, any reference
to Landlord's "knowledge" shall mean, refer and be limited to the actual
knowledge, without imputation of knowledge, of officers of the trustee of
Landlord having responsibility for the Building.

      6.12 INCORPORATION OF PRIOR AGREEMENT; AMENDMENTS. This Lease contains all
of the agreements of the parties to this Lease with respect to any matter
covered or mentioned in this Lease, whether oral or written, and no prior or
contemporaneous agreement or understanding pertaining to any such matter shall
be effective for any purpose. No provision of this Lease may be amended or added
to except by an agreement in writing signed by the parties to this Lease or
their respective successors in interest.

      6.13 AUTHORITY. If Tenant is a partnership, company, corporation or other
entity, each individual executing this Lease on behalf of Tenant represents and

performance of every covenant and condition of this Lease.

      6.15  SURVIVAL OF OBLIGATIONS. Notwithstanding anything contained in this
Lease to the contrary or the expiration or earlier termination of this Lease,
any and all obligations of either party accruing prior to the expiration or
termination of this Lease shall survive the expiration or earlier termination of
this Lease, and either party shall promptly perform all such obligations whether
or not this Lease has expired or terminated. Such obligations shall include any
and all indemnity obligations set forth in this Lease.

      6.16  CONSENT TO SERVICE. Tenant irrevocably consents to the service of
process of any action or proceeding at the address of the Premises, unless
Tenant has vacated the Premises and provided Landlord with written notice of
another address in which event service of process may be made at such other
address for Tenant. Nothing in this paragraph shall affect the right to serve
process in any other manner permitted by law.

             prior to the Committee's action.

         the sole purpose of determining the benefits payable under the Plan and

             4.2.2 At the time the Participant selects Investment Index(es) for
             new deferrals, a different allocation may be selected among
             Investment Funds for current Account balances, which may be
             different from the allocation for new deferrals. A Participant may
             change his or her investment allocation at any time, but not more
             frequently than once in any 30-day period, in accordance with the
             electronic, telephonic, or other methods designated by the
             Committee.

         4.3 Timing of Credits; Withholding. A Participant's deferred
         Compensation shall be credited to the Account and Subaccounts at the
         time it would have been payable to the Participant. Any withholding of
         taxes or other amounts with respect to deferred Compensation that is
         required by state, federal or local law shall be withheld from the
         Participant's corresponding nondeferred Compensation.

         4.4 Determination of Accounts and Subaccounts. Each Participant's
         Account shall consist of the balance of such Participant's account
         under the TSC Plan immediately prior to the Effective Date increased by
         any deferred Compensation credited to such Participant's Account
         pursuant to Section 3, reduced by any benefits distributed to the
         Participant and increased or decreased by the Earnings credited on the
         balance in the Account as of each day on which the Nasdaq National
         Market or the New York Stock Exchange is open.

         4.5 Vesting of Accounts. Each Participant shall be one hundred percent
         (100%) vested at all times in the amounts credited to such
         Participant's Account, Subaccount and Earnings thereon, for amounts
         attributable to deferrals.

         4.6 Statement of Accounts. The Committee shall give to each Participant
         a statement showing the balances in the Participant's Account and
         Subaccount(s) on a quarterly basis and at such other times as may be
         determined by the Committee.

5.       PLAN BENEFITS

         5.1 Early Withdrawals. A Participant's Account may be distributed to
         the Participant before termination of employment as follows:

             5.1.1 Election for In-Service Distribution. A Participant may elect
             in the Participation Agreement to have returned to such Participant
             any portion of the principal amount deferred by the Participation
             Agreement as soon as administratively practicable after the
             beginning of the fifth year following the commencement of the
             Deferral Period. The portion of the principal amount to be returned
             shall be elected in the Participation Agreement. The amount
             distributed shall be limited to the Account balance, if it is less
             than the principal amount deferred.

             5.1.2 Hardship Withdrawal. Upon a finding that a Participant or
             Beneficiary has suffered an Unforeseeable Emergency, the Committee
             may, in its sole discretion, make distributions from the
             Participant's Account. "Unforeseeable Emergency" means an
             unanticipated emergency that is caused by an event beyond the
             control of the Participant or Beneficiary and that would result in
             severe financial hardship to the individual if early withdrawal
             were not permitted. In no event shall declining earnings rates be
             considered an Unforeseeable Emergency. Any early withdrawal
             approved by the Committee shall be limited to the amount necessary
             to meet the emergency. If a Participant is deemed eligible to
             receive a hardship withdrawal, no additional deferrals shall be
             made for the Participant for the remainder of the Deferral Period
             in which withdrawal is made or for the immediately succeeding
             Deferral Period.

             5.1.3 Form of Payment. Withdrawals shall be paid in a lump sum and
             shall be charged to the Participant's Account as a distribution.

         5.2 Termination of Employment. If a Participant terminates employment
         with Employer for any reason, including death or disability, the
         Employer shall pay to the Participant (or the Participant's
         Beneficiary, in case of death) benefits equal to the balance in the
         Account.

                                       6
<PAGE>   9

         5.3 Form of Benefits. Except as provided below, benefits payable as a
         result of termination of employment shall be paid in the form elected
         by the Participant prior to the beginning of the first Deferral Period
         or as thereafter changed pursuant to Section 5.4. If the Participant
         participated in the TSC Plan prior to the Effective Date, benefits
         payable to the Participant hereunder shall be paid in the form elected
         under the TSC Plan. If a Participant's termination of employment is a
         Retirement or Disability, the form of benefit shall be, as elected by
         the Participant:

             5.3.1 A lump sum amount which is equal to the applicable Account
             balance; or

             5.3.2 Equal monthly installments of the Account amortized over a
             period of sixty (60), one hundred twenty (120), or one hundred
             eighty (180) months. Earnings on the unpaid balance shall continue
             to be credited to Subaccounts at the appropriate Investment Fund
             rate; or

             5.3.3 Equal annual installments of the Account amortized over a
             period of five (5), ten (10), or fifteen (15) years. Earnings on
             the unpaid balance shall continue to be credited to Subaccounts at
             the appropriate Investment Fund rate.

         If a Participant's termination of employment is a Termination, the form
         of benefit shall be, as elected by the Participant:

             5.3.4 A lump sum amount which is equal to the applicable Account
             balance; or

             5.3.5 Equal monthly installments of the Account amortized over a
             period of twelve (12), twenty-four (24), or thirty-six (36) months.
             Earnings on the unpaid balance shall continue to be credited to
             Subaccounts at the appropriate Investment Fund rate; or

             5.3.6 Equal annual installments of the Account amortized over a
             period of one (1), two (2), or three (3) years. Earnings on the
             unpaid balance shall continue to be credited to Subaccounts at the
             appropriate Investment Fund rate.

         Benefits payable due to a Participant's death shall be distributed as
         follows:

             5.3.7 If the Participant's death occurs before benefit payments
             have commenced, the Participant's Beneficiary shall receive payment
             in a lump sum.

             5.3.8 If the Participant's death occurs after benefit payments have
             commenced, the Participant's Beneficiary shall continue to receive
             payments in the form elected by the Participant.

                                       7
<PAGE>   10

         Notwithstanding the form elected, if the Participant's total Account is
         five thousand dollars ($5,000) or less as of the date the Participant's
         employment terminates, the benefit shall be paid in a lump sum.

         5.4 Change in Form of Benefits. A Participant may amend the form of
         benefit distribution previously selected at any time prior to the
         calendar year in which the Participant's employment terminates so long
         as the amendment does not increase the number of years during which
         payment is to be made. Notwithstanding the above, the Participant may
         not amend any distribution election made pursuant to Section 5.1.1,
         Election for In-Service Distribution.

         5.5 Disability Payments. If a Participant is to receive payments from
         the Plan due to Disability, and wishes to alter the form of benefit
         payment previously elected, the Participant shall submit a request to
         postpone payments until the Participant would have otherwise qualified
         for Retirement had the Participant remained employed at the Company in
         the full capacity of his or her duties. Amendment of the form of
         payment shall be subject to approval by the Committee. Any alteration
         of the elected payment shall be at the sole discretion of the Committee
         and the Committee reserves the right to deny any application to alter
         the elected payment form.

         5.6 Withholding Payroll Taxes. The Employer shall withhold from
         payments hereunder any taxes required to be withheld from such payments
         under federal, state or local law. A Beneficiary, however, may elect
         not to have withholding of federal income tax pursuant to Section 3405
         of the Internal Revenue Code, or any successor provision thereto.

         5.7 Valuation. The amount of a lump sum, monthly installment, or annual
         installment payment shall be based on the value of the Participant's
         Account on the date the Participant's employment terminates. Except as
         provided in Section 5.8, payments shall be made or commence within
         ninety (90) days after such date.

         5.8 Covered Employee. Notwithstanding Section 5.7, if any portion of a
         payment in a calendar year would be disallowed as a deduction to the
         Employer because the Participant is a "covered employee" for that
         calendar year under Section 162(m) of the Internal Revenue Code, that
         portion shall instead be paid in the immediately following

                                       8
<PAGE>   11

         calendar year, by January 30. This Section does not apply to early
         withdrawals under Section 5.1.

         5.9 Payment to Guardian. If a distribution is payable to a minor or to
         a person declared incompetent or to a person incapable of handling the
         disposition of property, the Committee may direct payment to the
         guardian, legal representative, or person having the care and custody
         of such minor, incompetent, or person. The Committee may require proof
         of incompetence, minority, incapacity or guardianship as it may deem
         appropriate prior to distribution. Such distribution shall completely
         discharge the Committee from all liability with respect to such
         benefit.

6.       BENEFICIARY DESIGNATION

         6.1 Beneficiary Designation. Each Participant shall have the right at
         any time to designate one or more persons or an entity as Beneficiary
         (both primary as well as secondary) to whom benefits under this Plan
         shall be paid in the event of a Participant's death prior to complete
         distribution of the Participant's Account. Each Beneficiary designation
         shall be in a written form prescribed by the Committee and will be
         effective only when filed with the Committee during the Participant's
         lifetime. The Beneficiary designated by a Participant under the TSC
         Plan shall continue in effect under this Plan until changed by such
         Participant. Designation by a married Participant of a Beneficiary
         other than the Participant's spouse shall not be effective unless the
         spouse executes a written consent that acknowledges the effect of the
         designation and is witnessed by a notary public, or the consent cannot
         be obtained because the spouse cannot be located.

         6.2 Amendments. Except as provided below, any nonspousal designation of
         Beneficiary may be changed by a Participant without the
         consent of such Beneficiary by the filing of a new designation with the
         Committee. The filing of a new designation shall cancel all
         designations previously filed.

         6.3 Change in Marital Status. If the Participant's marital status
         changes after the Participant has designated a
         Beneficiary, the following shall apply:

             6.3.1 If the Participant is married at death but was unmarried when
             the designation was made, the designation shall be void unless the
             spouse has consented to it in the manner prescribed above.

                                       9
<PAGE>   12

             6.3.2 If the Participant is unmarried at death but was married when
             the designation was made:

             6.3.2.1  The designation shall be void if the spouse was named as
             Beneficiary.

             6.3.2.2 The designation shall remain valid if a nonspouse
             Beneficiary was named.

             6.3.3 If the Participant was married when the designation was made
             and is married to a different spouse at death, the designation
             shall be void unless the new spouse has consented to it in the
             manner prescribed above.

         6.4 No Beneficiary Designation. If any Participant fails to designate a
         Beneficiary in the manner provided above, or if the Beneficiary
         designated by a deceased Participant dies before the Participant or
         before complete distribution of the Participant's benefits, the
         Participant's Beneficiary shall be the person in the first of the
         following classes in which there is a survivor:

             6.4.1 The Participant's surviving spouse;

             6.4.2 The Participant's children in equal shares, except that if
             any of the children predeceases the Participant but leaves issue
             surviving, then such issue shall take by right of representation
             the share the parent would have taken if living;

             6.4.3 The Participant's estate.

7.       ADMINISTRATION

         7.1 Committee; Duties. This Plan shall be administered by the Committee
         which shall be comprised of the outside directors serving on the
         Board's Compensation Committee or a committee of at least two members
         composed of non-Participants, designated by the Board's Compensation
         Committee. The Committee shall have the authority to make, amend,
         interpret and enforce all appropriate rules and regulations for the
         administration of the Plan and decide or resolve any and all questions,
         including interpretations of the Plan, as may arise in such
         administration. A majority vote of the

                                       10
<PAGE>   13

         Committee members shall control any decision. Members of the Committee
         may be Participants under this Plan.

         7.2 Agents. The Committee may, from time to time, employ agents and
         delegate to them such administrative duties as it sees fit, and may
         from time to time consult with counsel who may be counsel to the
         Company.

         7.3 Binding Effect of Decisions. The decision or action of the
         Committee with respect to any question arising out of or in connection
         with the administration, interpretation and application of the Plan and
         the rules and regulations promulgated hereunder shall be final,
         conclusive and binding upon all persons having any interest in the
         Plan.

         7.4 Indemnity of Committee. The Company shall indemnify and hold
         harmless the members of the Committee to the fullest extent authorized
         by the Delaware General Corporation Law pursuant to "Article VIII
         Indemnification" of the Company's By-Laws.

8.       CLAIMS PROCEDURE

         8.1 Claim. Any person claiming a benefit, requesting an interpretation
         or ruling under the Plan, or requesting information under the Plan
         shall present the request in writing to the Committee, which shall
         respond in writing as soon as practicable.

         8.2 Denial of Claim. If the claim or request is denied, the written
         notice of denial shall state:

         has not received a response within thirty (30) days may request review
         by notice given in writing to the Committee. The claim or request shall
         be reviewed by the Committee which may, but shall not be required to,
         grant the claimant a hearing. On review, the claimant may have
         representation, examine pertinent documents, and submit issues and
         comments in writing.

                                       11
<PAGE>   14

         8.4 Final Decision. The decision on review shall normally be made
         within sixty (60) days. If any extension of time is required for a
         hearing or other special circumstances, the claimant shall be notified

         shall be in writing and shall state the reasons and the relevant Plan
         provisions. All decisions on review shall be final and bind all parties
         concerned.

9.       AMENDMENT AND TERMINATION OF PLAN

         9.1 Amendment. The Board may at any time amend the Plan by written
         instrument, notice of which shall be given to all Participants and to
         Beneficiaries receiving installment payments, subject to the following:

             9.1.1 Preservation of Account Balance. No amendment shall reduce
             the amount accrued in any Account to the date such notice of the
             amendment is given.

             9.1.2 Changes in Investment Indexes. The Committee may change the
             Investment Indexes available to Participants for any date
             subsequent to the date of such change.

         9.2 Employer's Right to Terminate. The Board may at any time partially
         or completely terminate the Plan if, in its judgment, the tax,
         accounting, or other effects of the continuance of the Plan, or
         potential payments thereunder would not be in the best interest of the
         Employer.

             9.2.1 Partial Termination. The Board may partially terminate the
             Plan by instructing the Committee not to accept any additional
             Participation Agreements. If such a partial termination occurs, the
             Plan shall continue to operate and be effective with regard to
             Participation Agreements entered into prior to the effective date
             of such partial termination.

             9.2.2 Complete Termination. The Board may completely terminate the
             Plan by instructing the Committee not to accept any additional
             Participation Agreements, and by terminating all ongoing
             Participation Agreements. If such a complete termination occurs,
             the Plan shall cease to operate and the Employer shall pay out each
             Account. Unless the Committee determines otherwise, payment shall
             be made as a lump sum or in equal monthly installments over the
             following period, based on the Account balance:

                                       12
<PAGE>   15

                Account Balance                            Payout Period
                ---------------                            -------------
                $50,000 or less                            Lump Sum
                More than $50,000 but less than $250,000   3 Years
                $250,000 or More                           5 Years

         Earnings at the appropriate rate shall continue to be credited on the
         unpaid balance in each Account. The Employer reserves the right to pay
         each Account in a lump sum, notwithstanding the above schedule.

10.      MISCELLANEOUS

         10.1 Unfunded Plan. This Plan is an unfunded Plan maintained primarily
         to provide deferred compensation benefits for a select group of
         "management or highly-compensated employees" within the meaning of
         Sections 201, 301 and 401 of the Employee Retirement Income Security
         Act of 1974, as amended ("ERISA"), and therefore is exempt from the
         provisions of Parts 2, 3 and 4 of Title I of ERISA. Accordingly, the
         Board may terminate the Plan and make no further benefit payments or
         remove certain employees as Participants if it is determined by the
         United States Department of Labor, a court of competent jurisdiction,
         or an opinion of counsel that the Plan constitutes an employee pension
         benefit Plan within the meaning of Section 3(2) of ERISA (as currently
         in effect or hereafter amended) which is not so exempt.

         10.2 Unsecured General Creditor. Participants and their Beneficiaries,
         heirs, successors, and assigns shall have no secured legal or equitable
         rights, interest or claims in any property or assets of the Employer,
         nor shall they be Beneficiaries of, or have any rights, claims or
         interest in any assets or financial instruments which may be acquired
         by the Employer. Except as provided in Section 10.3, such assets of the
         Employer shall not be held under any trust for the benefit of
         Participant, their Beneficiaries, heirs, successors or assigns, or held
         in any way as collateral security for the fulfilling of the obligations
         of the Employer under this Plan. Any and all of the Employer's assets
         and policies shall be, and remain, the general, unpledged, unrestricted
         assets of the Employer. The Employer's obligation under the Plan shall
         be that of an unfunded and unsecured promise to pay money in the
         future.

                                       13
<PAGE>   16

         10.3 Trust Fund. At its discretion, the Employer may establish one or
         more trusts, with such trustees as the Board may approve, for the
         purpose of providing for the payment of benefits owed under the Plan.
         Although such a trust shall be irrevocable, its assets shall be held
         for payment of all the Employer's general creditors in the event of
         insolvency. To the extent any benefits provided under the Plan are paid
         from any such trust, the Employer shall have no further obligation to
         pay them. If not paid from the trust, such benefits shall remain the
         obligation of the Employer. Notwithstanding the existence of such a
         trust, it is intended that the Plan be unfunded for tax purposes and
         for purposes of Title I of ERISA.

         10.4 Nonassignability. Neither a Participant nor any other person shall
         have any right to commute, sell, assign, transfer, pledge, anticipate,
         mortgage or otherwise encumber, transfer, hypothecate or convey in
         advance of actual receipt the amounts, if any, payable hereunder, or
         any part thereof, which are, and all rights to which are, expressly
         declared to be unassignable and nontransferable. No part of the amounts
         payable shall, prior to actual payment, be subject to seizure or
         sequestration for the payment of any debts, judgments, alimony or
         separate maintenance owed by a Participant or any other person, nor be
         transferable by operation of law in the event of a Participant's or any
         other person's bankruptcy or insolvency.

         10.5 Not a Contract of Employment. This Plan shall not constitute a
         contract of employment between the Employer and the Participant.
         Nothing in this Plan shall give a Participant the right to be retained
         in the service of the Employer or to interfere with the right of the
         Employer to discipline or discharge a Participant at any time.

         10.6 Protective Provisions. A Participant will cooperate with the
         Employer by furnishing any and all information requested by the
         Employer as the Employer may reasonably require.

         10.7 Governing Law. The provisions of this Plan shall be construed and
         interpreted according to the laws of the State of Illinois, except as
         preempted by federal law.

         10.8 Validity. In case any provision of this Plan shall be held illegal
         or invalid for any reason, said illegality or invalidity shall not
         affect the remaining parts hereof, but this Plan shall be construed and
         enforced as if such illegal and invalid provision had never been
         inserted herein.

         10.9 Notice. Any notice required or permitted under the Plan shall be
         sufficient if in writing and hand delivered or sent by registered or

         delivery or, if delivery is made by mail, as of the date shown on the
         postmark on the receipt for registration or certification. Mailed
         notice to the Committee shall be directed to the Company's address.
         Mailed notice to a Participant or Beneficiary shall be directed to the
         individual's last known address in the Employer's records.

         10.10 Successors. The provisions of this Plan shall bind and inure to
         the benefit of the Employer and its successors and assigns. The term
         successors as used herein shall include any corporate or other business
         entity which shall, whether by merger, consolidation, purchase or
         otherwise acquire all or substantially all of the business and assets
         of the Employer, and successors of any such corporation or other
         business entity.
