Tenant Improvements or changes thereto. However the Landlord warrants that the
roof, the structure, and the parking lot of the Building, and the plumbing and
HVAC servicing the Additional Leased Premises are all in good working order as
of the date of the execution of this Amendment. The Tenant shall be entitled to
receive the benefit of existing manufacturers' and contractors' warranties, if
any, regarding the Additional Leased Premises.

     B.   Subject to Article IV, Section C below, the Tenant shall be
responsible and shall pay for the cost of any and all improvements installed to
the Additional Leased Premises it determines necessary (the "Tenant Work"). The
Tenant shall obtain and pay for the cost of all permits required from the
Village for the construction of the Tenant Work performed by the Tenant or the
Tenant's contractors. The Tenant shall be responsible for the performance of all
Tenant Work in accordance with and pursuant to the following:

     (a)  Prior to the commencement of the construction of the Tenant Work, the
     Tenant shall submit to the Landlord the following: (i) the architectural
     plans and specifications (the "Tenant Plans"); (ii) a sworn contractor's
     statement listing all the contractors and/or subcontractors who will
     perform the Tenant Work, their addresses, telephone numbers, and the amount

     and/or subcontractors; (iv) copies of all permits from the Village. The
     Tenant Plans shall be subject to the prior written approval of the
     Landlord, which approval or disapproval shall be given by the Landlord
     within five (5) business days after receipt by the Landlord of the Tenant
     Plans. If approval or disapproval is not given by the Landlord within the
     said five (5) day period, it shall be conclusively presumed that the Tenant
     Plans have been approved by the Landlord. The Tenant may not commence the
     Tenant Work until this approval has been obtained from the Landlord.

     (b)  All Tenant Work shall be constructed and/or installed in a good and
     workmanlike manner and in accordance with all applicable federal, state,
     municipal and local laws and building codes, fire regulations and
     requirements of the Fire Insurance Rating Bureau.

     (c)  Tenant agrees at its expense, to obtain and maintain fire and extended
     coverage insurance, public liability insurance and Workman's Compensation

     (d)  All roof penetrations required by the Tenant, if any, shall be by the
     Landlord's roofing contractor at the Tenant's expense; provided however the
     Tenant shall have the right to review and approve all of the Landlord's
     contractor's charges, which charges shall be competitive in the
     marketplace. No attachment to or drilling or welding to or of the
     Building's structural systems or exterior walls is allowed without the
     express written permission of the Landlord, which shall not be unreasonably
     withheld or delayed.

     (e)  Any equipment and/or fixtures to be hung from the ceiling shall be
     attached to the structural members only, and not from any duct work,
     conduit, decking, ceiling grid and/or acoustical tiles.

     (f)  Tenant shall cause, at its expense, the daily removal of all trash,
     rubbish and surplus material from the Building and the Additional Leased

     cause the construction of the Tenant Work to promptly commence and will use
     every reasonable effort to cause the Tenant Work to be completed as soon as
     possible.

      C.  As an inducement to enter into this Amendment, the Landlord agrees to
pay to the Tenant the sum of One Hundred Thousand Dollars ($100,000) (the
"Tenant Inducement"), payable as follows:

     (a)  Within fifteen (15) days of the receipt by the Landlord of invoices
     and acceptable lien waivers from the Tenant's contractor(s) for the Tenant
     Work, the Landlord shall pay to the Tenant the amount of said invoices, not
     to exceed the amount of the Tenant Inducement, provided the Tenant has not
     committed an uncured Event of Default at the time of the payment; and

     (b)  The unpaid balance of the Tenant Inducement, if any, shall be paid to
     the Tenant within fifteen (15) days of the receipt by the Landlord of
     acceptable final lien waivers from all Tenant contractor(s) provided the
     Tenant has not committed an uncured Event of Default at the time of the
     payment. Tenant shall provide a copy of the occupancy permit upon receipt
     from Village.

The Landlord does not require the Tenant to expend the entire amount of the
Tenant Inducement on the cost of the Tenant Work, and should the cost of the
Tenant Work be less than the Tenant Inducement, the unexpended portion of the
Tenant Inducement will be paid to the Tenant upon compliance of its obligations
under Subsection C (b) above.

Illinois 60005 (hereinafter referred to as LAMCO), or to such other agent or at

                                   ARTICLE III
                                 ADDITIONAL RENT
                                 ---------------

It is mutually understood that the Fixed Rent does not include therein a
provision for the payment of taxes (as hereinafter defined and referred to as
TAXES) on the Building, nor does it include therein a provision for the payment
of materials, costs, expenses, and services incurred in the operation and
maintenance of the Building (as hereinafter defined and referred to as OPERATING
EXPENSES). Starting on the Commencement Date, Tenant agrees to pay to Landlord
seventy-six point eighty-five percent (76.85%), (which percentage is hereinafter
referred to as the TENANT'S PRORATA SHARE and is calculated by dividing the
Rentable Square Feet by 79,715, the total square feet of the Building) of the
total Taxes and Operating Expenses (hereinafter collectively referred to as
ADDITIONAL RENT) of the Building in addition to the Fixed Rent, as more fully
provided for hereinafter:

         A. Taxes are defined as those taxes levied or assessed against the
         Building by any lawful authority for each calendar year of the Term,
         regardless of whether or not the amount assessed or levied is payable
         in that year or in a subsequent year. Specifically, Taxes shall mean
         all taxes and assessments, of every kind and nature, special or
         otherwise, including without limitation, general real property taxes,
         personal property taxes imposed upon fixtures, machinery, apparatus
         systems and appurtenances in, upon, or used in connection with the
         Building or the operation thereof, sewer rents, water rents, special
         assessments, transit taxes, any tax or excise on Rental, or any other
         tax (however described) on account of Rental received for use and
         occupancy of any or all of the Building, whether such Taxes are imposed
         by the United States, the State of Illinois, the County of Lake, the
         Village of Libertyville (hereinafter referred to as the VILLAGE), or
         any other governmental authority or agency or political subdivision.
         There shall also be included in Taxes

                                       2
<PAGE>

         all fees and costs including, without limitation, attorney's fees paid
         or incurred by Landlord in seeking to obtain a reduction of or a limit
         on an increase in Taxes, and objecting to or defending against the levy
         of same. If at any time during the Term the method of taxation then
         prevailing shall be altered so that any tax, assessment, levy,
         imposition, or charge or any part thereof, shall be imposed upon
         Landlord (or upon the beneficiaries of Landlord) in place, or partly in
         place, of any such Taxes or increase therein heretofore described in
         this subparagraph and/or the same shall be measured by or be based in
         whole or in part upon the Building or the Rental or other income
         therefrom, then all such taxes, assessments, impositions, levies, or
         charges or part thereof shall be included in Taxes, to the extent that
         such items would be payable if the building were the only property
         and/or income of Landlord (or the only property and/or income of the
         beneficiaries of Landlord) subject thereto. Taxes shall not include any
         Federal, State or local municipal income taxes, capital stock taxes, or
         estate or inheritance taxes, other than as specifically provided for
         above, or penalties or interest on the late payment of installments of
         Taxes. From time to time, the Landlord, in its reasonable discretion,
         shall take all reasonable and proper steps and procedures to minimize
         Taxes, including, but not limited to, the contesting of or objecting to
         increases of the determination of the fair market value of the Building
         by the Lake County Assessor for real estate tax purposes and the
         objecting to the tax rate imposed by the taxing authorities. The
         Landlord does not warrant that any such steps or procedures will result
         in the reduction or minimization of Taxes.

         B. Operating Expenses are defined as all expenses and costs incurred by
         or paid on behalf of the Landlord and which, in accordance with
         generally accepted accounting practice as applied to the operation,
         repair, management, and maintenance of an office/industrial/warehouse
         building in the Lake County, Illinois area, are properly charged,
         expensed or amortized to such ownership, operation, management, and
         maintenance of the Building, including without limitation, the cost of
         window washing, repairs and maintenance, parking lot and common area
         cleaning, insurance, landscaping, snow removal, janitorial services,
         common area lighting, parking lot lighting, heating and air
         conditioning of common areas, security services, pest control,
         management fees, office expenses, service and/or lease contracts on
         equipment used in common in the Building, and professional fees.
         Operating Expenses shall not include: (a) interest and principal
         payments on mortgages and other debt service and ground lease payments;
         (b) franchise or income taxes imposed upon Landlord or Taxes charged to
         the Building as provided in subparagraph A above; (c) the cost or fees
         for any lease, work, or service performed in any instance for an
         individual tenant and not for all tenants in common; (d) capital
         improvements and replacements; (e) leasing commissions and costs
         incident thereto; (f) attorneys fees and costs connected with ownership
         and organization of the Landlord and not strictly related to the
         operation of the Building; (g) costs for services sold to tenants and
         for which Landlord is entitled or would ordinarily be entitled to be
         reimbursed directly by tenants and not chargeable to all tenants as
         Operating Expenses; (h) depreciation and amortization, except as
         allowed pursuant to above or on equipment and installations charged to
         tenants as Operating Expenses; (i) fees or other compensation paid to
         affiliates of Landlord for services to the Building, to the extent that
         the costs of such services exceed competitive costs of services of
         equal quality and quantity were they not so rendered by an affiliate;
         (j) advertising and promotion expenses; (k) wages, salaries, or other
         compensation paid to any executive employees above the grade of
         Building Manager; (l) expenses directly caused by the intentional
         violation by Landlord of any lease pertaining to the Building; (m)
         legal fees in enforcing leases of other tenants; and (n) costs
         occasioned by fire, windstorm, or other casualty or for any other
         reason, which costs are reimbursed to

                                       3
<PAGE>

         Landlord by insurers, other parties, or by governmental authorities in
         eminent domain.

         C. Operating Expenses and Taxes, provided for herein, shall be payable
         by Tenant to Landlord in monthly installments of 1/12th of the total
         amount due or estimated to be due from the Tenant in any one calendar
         year. Starting on the Commencement Date, the Landlord estimates the
         Tenant's obligation for Operating Costs and Taxes will be Seven
         Thousand Six Hundred and Eighty-Five and 08/100 Dollars ($7685.08) per
         month.

         D. On the commencement of each subsequent calendar year of the Term,
         the Tenant shall continue to pay the monthly installment of Taxes and
         Operating Costs paid in the previous year, until the Landlord delivers
         to the Tenant a written statement, certified to be true and correct by
         the Landlord, hereinafter referred to as the ANNUAL STATEMENT,
         indicating, among other items, in reasonable detail the previous
         calendar year's total Taxes and Operating Costs. The Landlord will
         endeavor to supply the Annual Statement to the Tenant by July 1st of
         each calendar year. Based upon the Annual Statement, the Tenant may be
         required to pay an additional sum, if the total of the monthly deposits
         for Taxes and Operating Costs received from the Tenant by the Landlord
         in the previous calendar year was less than the actual Taxes and
         Operating Costs attributable to the Tenant as set forth in the Annual
         Statement. Said additional sum (considered within the definition of
         Additional Rent) shall be due from the Tenant within thirty (30) days
         after the mailing of the Annual Statement to the Tenant. In the event
         the monthly deposits paid by the Tenant in the previous calendar year
         for Taxes and Operating Costs were more than Tenant's actual
         obligation, as set forth in the Annual Statement, Tenant shall be
         entitled to a refund, which shall be applied to the succeeding month's
         Rental to the extent of said overpayment, or if the Lease has expired,
         then the amount of said refund shall be paid by the Landlord to the
         Tenant within ten (10) days of the mailing of the Annual Statement,
         assuming there are no sums due from the Tenant to the Landlord, or if
         there are any sums due from the Tenant to the Landlord, then such
         amount shall be applied to the payment of such sums.

         E. The Annual Statement may further provide for an increase or decrease
         of the amount of the monthly installment due from the Tenant to the
         Landlord for Taxes and Operating Costs, should the Taxes and Operating
         Costs of the previous calendar year have either increased or decreased.
         In the event the Landlord increases the monthly installment, the Tenant
         shall further pay to the Landlord, within thirty (30) days of the
         mailing of the Annual Statement, a lump sum equal to the amount of the
         monthly increase multiplied by the number of months then elapsed
         between January 1 of the then current calendar year and the month in
         which the Annual Statement is delivered to the Tenant. In the event the
         Landlord decreases the monthly installment of Taxes and Operating
         Costs, the Tenant shall be entitled to a refund equal to the amount of
         the monthly decreased multiplied by the number of months then elapsed
         between January 1 of the then current calendar year and the month in
         which the Annual Statement is delivered to the Tenant, which sum shall
         be applied to the succeeding month's Rental, or if the Lease has
         expired, then such amount shall be paid by the Landlord to the Tenant
         within ten (10) days of the mailing of the Annual Statement, assuming
         there are no sums due from the Tenant to the Landlord, or if there are
         any sums due from the Tenant to the Landlord, then such amount shall be
         applied to the payment of such sums.

         F. The Tenant, or its representative, shall have the right to examine
         and audit the Landlord's books and records with respect only to the
         items relating to Additional Rent in the Annual Statement, after
         providing the Landlord with a prior written

                                       4
<PAGE>


         Notice (as Notice is defined hereinafter) requesting such examination
         (hereinafter referred to as FIRST EXCEPTION NOTICE), within thirty (30)
         days following the date of the mailing of the Annual Statement to the
         Tenant. Such examination or audit shall be made at the Landlord's place
         of business during normal business hours. Within thirty (30) days after
         the completion of the audit, which must take place within ninety (90)
         days of the First Exception Notice, the Tenant must deliver to the
         Landlord a written exception of any items or calculations specified in
         the Annual Statement, stating in particularity the grounds for said
         exception (hereinafter referred to as SECOND EXCEPTION NOTICE). Failure
         on the part of the Tenant to serve on the Landlord the First Exception
         Notice and/or the Second Exception Notice, as provided for
         hereinabove, all within the time periods specified, shall result in the
         binding and conclusive presumption of the approval by the Tenant of the
         computations and charges set forth in the Annual Statement and such
         Additional Rent charges shall be considered as final and accepted and
         binding upon and by the Tenant and may not be contested at any time
         thereafter; the Tenant thereafter forever waiving its right to contest
         such Additional Rent charges set forth in the particular Annual
         Statement. In the event the Tenant properly serves a Second Exception
         Notice upon the Landlord and the Landlord and Tenant cannot resolve the
         controversy within sixty (60) days after the date of the Second
         Exception Notice, then the Tenant shall have the right, within said
         sixty (60) day period, to submit to the Landlord a Notice electing to
         resolve the dispute in accordance with the procedure set forth in
         Article XX herein. If submitted to arbitration in accordance with
         Article XX, and the decision of the arbitrators is in favor of the
         Landlord, or if an overstatement of an amount chargeable to the Tenant
         as provided in the Annual Statement, as determined by the arbitration,
         is less than 5% of the total amount due from the Tenant for Additional
         Rent for the year in question, the cost of the arbitration, including,
         but not limited to, the reasonable attorneys' and accounts' fees
         incurred by the Landlord, shall be paid by the Tenant; otherwise the
         reasonable cost thereof, including, but not limited to, the reasonable
         attorneys' and accountants' fees incurred by the Tenant, will be paid
         by the Landlord. Any overstatement shall be applied to the succeeding
         month's Rental, or if the Lease has expired, then such amount shall be
         paid by the Landlord to the Tenant within ten (10) days of the
         arbitrators' written decision, assuming there are no sums due from the
         Tenant to the Landlord, or if there are any sums due from the Tenant to
         the Landlord, then such amount shall be applied to the payment of such
         sums. Failure on the part of the Tenant to submit the controversy to
         dispute resolution in accordance with Article XX within the time
         periods specified herein shall result in a conclusive and final waiver
         of the Tenant's right to contest the charges set forth in the Annual
         Statement or in the Second Exception Notice, and such Additional Rent
         charges shall be considered as final and accepted and binding upon and
         by the Tenant. Regardless of the provisions set forth in this
         subparagraph and whether or not the tenant properly contests any
         Additional Rent charges in any Annual Statement, the Tenant must pay,
         when due, all contested Additional Rent charges, subject to its right
         to secure a refund or credit therefor should the Tenant prevail
         successfully in any of the procedures set forth herein.

         G. The provisions of this Article III shall survive the termination of
         this Lease.

                               TENANT COVENANTS
                               ----------------

         A. Other than specifically provided for hereinabove, Tenant shall not
erect or install any other exterior signs or interior window or door signs,
advertising media, or window or door lettering or placards without Landlord's
prior written consent. Tenant shall not install any exterior lighting, shades,

         B. Tenant will not commit any act which will cause a mechanic's lien to
be filed against the Leased Premises or against the Building. After the initial
construction of the Tenant's Improvements, the Tenant shall not make any
repairs, remodeling, decorating, alterations or additions to the Leased Premises
(hereinafter referred to as TENANT ALTERATIONS) without first procuring
Landlord's written consent (which shall not be unreasonably withheld or
delayed). The Tenant shall deliver to Landlord plans and specifications of the
Tenant Alterations and copies of the proposed contracts and necessary permits
before the Landlord will consider approval or disapproval. In the event the
Landlord approves the proposed Tenant Improvements, the Tenant shall then
furnish indemnification against liens, costs, damages, and expenses as may be
reasonably required by Landlord. At the termination of this Lease, all Tenant
Alterations, which in any manner are attached to the floors, walls, or ceilings,
shall remain upon and be surrendered with the Leased Premises as part thereof,
furthermore any floor covering which may be cemented or otherwise affixed to the
floor shall likewise become the property of Landlord, all without compensation
or credit to Tenant. Provided the Tenant notifies the Landlord, in writing, at
the time of the installation or construction of the Tenant Alterations, that it
intends to remove same at the end of the Term, it may do so provided it restores
the Leased Premises to its condition as existed prior to the installation or
construction of the Tenant Alterations, and further, such removal shall not
cause material damage to the Leased Premises.

         C. Tenant agrees to indemnify and save Landlord harmless against any
and all claims, demands, damages, costs, and expenses, arising from the conduct
or management of the business conducted by Tenant in the Leased Premises, or
from the construction of Tenant Alterations to the Leased Premises, or from any
breach or default on the part of Tenant in the performance of any covenant or
agreement on the part of Tenant to be performed pursuant to the terms of this
Lease, or from any act or negligence of Tenant, its agents, contractors,
servants, employees, subleasees, concessionaires, or licensees, in or about the
Leased Premises and the Building. In case of any action or proceeding brought
against Landlord by reason of any such claim, upon Notice from Landlord, Tenant
covenants to defend such action and the Landlord's interest by competent counsel
(competent in the Landlord's reasonable judgement only). To the extent not
expressly prohibited by law. Tenant releases Landlord, its agents, servants, and
employees from, and waives all claims to damages to person or property,
sustained by the Tenant or by any

                                      12
<PAGE>


other occupant of the Leased Premises, the Building, or by any other person,
resulting directly or indirectly from fire or other casualty, because of
existing or future conditions, defects, matters, or things in the Leased
Premises or any part thereof; or from any equipment or appurtenances therein or
from any accident in or about the Building, EXCEPT in the event the damages are
caused by the negligence or wrongful intentional acts of the Landlord or its
employees, agents, or servants. All personal property belonging to the Tenant or
any occupant of the Leased Premises shall be there at the risk of the Tenant or
other person only, and the Landlord shall not be liable for damages thereto or
theft or misappropriation thereof.

         D. Tenant shall not carry any stock of goods or do anything in or about
the Leased Premises which will in any way tend to increase insurance rates on
said Leased Premises or the Building in which the same are located. If Landlord
shall consent to such use, Tenant agrees to pay any reasonable increase in
premiums for insurance against loss by fire or extended coverage risks resulting
from the business carried on in the Leased Premises by Tenant. After the Tenant
Improvements have been constructed and completed and the Tenant thereafter
installs any additional electrical equipment that overloads the power lines to
the Building. Tenant shall at its own expense make whatever changes are
necessary to comply with the requirements of insurance underwriters and
insurance rating bureaus and governmental authorities having jurisdiction.

         E. Tenant agrees to procure and maintain a policy or policies of
insurance at its own cost and expense, insuring Landlord and Tenant from all
claims, demands, or actions for injury to or death arising out of any one
accident to the limit of $5,000,000, and for damage to property in an amount of
not less than $1,000,000, made by or on behalf of any person or persons, firm or
corporation arising from, related to, or connected with the conduct and
operation of the Leased Premises in the Building. All said policies shall name
the Landlord as an additional insured party. Said insurance shall not be subject
to cancellation except after at least ten (10) days prior written Notice to
Landlord. A duly executed certificate for the same shall be deposited with
Landlord on or before the Commencement Date and within thirty (30) days after
the expiration of the term of such coverage upon renewal of same. If tenant
fails to comply with such requirement, Landlord may obtain such insurance and
keep same in effect, and Tenant shall pay the Landlord the premium cost thereof,
plus ten percent (10%), within thirty (30) days after billing of same by the
Landlord, said sum to be considered as Additional Rent; and/or Landlord may
elect to regard such non compliance as an Event of Default (as defined
hereinafter).

         F. Tenant represents, warrants, and covenants to Landlord that Tenant
shall at no time (a) use or permit the use of the Leased Premises, the Building
and/or the Site for the generation, manufacture, production, storage, release,
discharge, or disposal of Hazardous Materials (as hereinafter defined) except in
accordance with Environmental Regulations (as hereinafter defined); or (b) to
transport Hazardous Materials to or from the Leased Premises, except in
accordance with Environmental Regulations; or (c) perform any act or action
whatsoever which violates any Environmental Regulations; and/or (d) allow or
permit any other person or entity to do any of the above:

         (a) The term HAZARDOUS MATERIALS is defined as and includes, without
         limitation, any flammable explosives, radioactive materials, asbestos
         and asbestos containing materials, hazardous wastes, hazardous or toxic
         substances, or related materials defined in the Comprehensive
         Environmental Response, Compensation and Liability Act of 1980, as
         amended (42 U.S.C. Sections 9601, et seq.), the Hazardous Materials
         Transportation Act, as amended (49 U.S.C. Sections 1801, et seq.), the
         Resource Conservation and Recovery Act of 1976, as amended (42 U.S.C.
         Sections 6901, et seq.),

                                      13

         and in the regulations adopted and publications promulgated pursuant
         thereto, or any other federal, state, or local environmental laws,
         ordinances, rules, or regulations dealing with hazardous materials.

         (b) The term ENVIRONMENTAL REGULATIONS is defined as all federal,
         state, and local laws, including all zoning laws or ordinances, and all
         regulations, codes, requirements, public and private land use
         restrictions, rules and orders which relate to or govern Hazardous
         Materials, and/or the environmental conditions in, on, under, or about
         the Leased Premises, the Building or the Site, in force at the time of
         the execution of the Lease and at any time during the Term.

         (c) Tenant shall assume sole and full responsibility for, and shall
         remedy at its sole cost and expense, all such violations of any
         Environmental Regulations caused by it or by introducing Hazardous
         Materials into the Leased Premises or the Building or Site, or on any
         adjacent property. Tenant shall at no time use, generate, release,
         store, treat, dispose of, or otherwise deposit in or about the Leased
         Premises any Hazardous Materials except in accordance with
         Environmental Regulations; or permit or allow any third party to do so,
         without Landlord's express, prior, written consent. Tenant's compliance
         with the terms of the Article and with all Environmental Regulations
         shall be at Tenant's sole cost and expense.

         (d) Tenant shall provide Landlord with written notification,
         immediately upon the discovery or notice or upon having reasonable
         grounds to suspect, by Tenant, its successors, assigns, licensees,
         invitees, employees, and/or agents, that any provision of this Article
         has not been strictly complied with; and including, but not by
         exclusion of other circumstances requiring notice, Tenant shall give
         prompt written Notice to Landlord of (a) any proceeding or inquiry by
         any governmental authority with respect to the Leased Premises, the
         Building or the Site of any Hazardous Substance on the Leased Premises,
         the Building or the Site or the migration thereof from or to other
         property; (b) all claims made or threatened by any third party against
         Tenant, Landlord, or the Leased Premises relating to any loss or injury
         resulting from any Hazardous Substance; and (c) Tenant's discovery of
         any occurrence or condition on any property adjoining or in the
         vicinity of the Leased Premises, the Building or the Site that
         threatens to cause the Leased Premises, the Building or the Site or any
         part thereof to be subject to or in violation of any Environmental
         Regulations.

         (e) It shall be an Event of Default (as defined herein) under this
         Lease, entitling Landlord to exercise any of its rights and remedies
         under this Lease, if any provision of this Article is not strictly
         complied with at all times. Landlord's election to conduct inspections
         of the Leased Premises shall not be construed as approval of Tenant's
         use of the Leased Premises or any activities conducted thereon, and
         shall in no way constitute an assumption by Landlord of any
         responsibility whatsoever regarding Tenant's use of any Hazardous
         Materials.

         (f) In the event the Tenant violates its representations, covenants,
         warranties, and obligations set forth in this Article, the Tenant shall
         defend, indemnify, and hold harmless Landlord, the Landlord's
         mortgagee(s), and the Landlord's Beneficiaries, employees, and agents
         from and against any claims, demands, penalties, fines, liabilities,
         settlements, damages, costs or expenses of whatever kind or nature,
         known or unknown, contingent or otherwise, arising out of or in any way
         related to the acts and omissions of Tenant, Tenant's officers,
         directors, employees, agents, contractors, subcontractors, subtenants
         and invitees with respect to (a) the generation, manufacture,
         operations involving, transport, treatment, storage,

                                       14
<PAGE>


         handling, production, processing, disposal, release or threatened
         release of any Hazardous Materials in violation of Environmental
         Regulations, which are on, from, or affecting the Leased Premises, the
         Building or the Site, (b) any personal injury (including wrongful
         death) or property damage (real or personal) arising out of or related
         to such Hazardous Materials; (c) any lawsuit brought or threatened,
         settlement reached, or governmental order relating to such Hazardous
         Materials or violation of Environmental Regulations; and (d) any
         violations of laws, orders, regulations, requirements, or demands of
         government authorities, or any reasonable policies or requirements of
         Landlord, which are based upon or in any way related to such Hazardous
         Materials or violations of Environmental Regulations, including,
         without limitation, reasonable attorneys and consultant fees,
         investigation and laboratory fees, court costs, and litigation
         expenses. This indemnification shall survive the termination,
         cancellation, and surrender of this Lease however effectuated.

         (g) In the event this Lease is terminated, cancelled, or surrendered
         for any reason whatsoever, Tenant shall deliver the Leased Premises to
         Landlord free of any and all Hazardous Materials so that the condition
         of the Leased Premises shall conform with all Environmental Regulations
         affecting the Leased Premises, subject to any conditions existing prior
         to the Commencement Date.

         (h) In the event that as a result of the Tenant use of the Leased
         Premises, any investigation, site monitoring, containment, cleanup,
         removal, restoration, or other remedial work of any kind or nature,
         hereinafter referred to as the REMEDIAL WORK, is required under
         Environmental Regulations and/or any applicable local, state or federal
         law or regulation, or any judicial order, or by any governmental entity
         because of, or in connection with, the current or future presence,
         release of a Hazardous Substance in or into the air, soil, ground
         water, surface water, or soil vapor at, on, about, under, or within the
         Leased Premises (or any portion thereof), the Building and/or the Site,
         Tenant shall within thirty (30) days after written demand for
         performance thereof by Landlord (or such shorter period of time as may
         be required under any Environmental Regulations or any applicable law,
         regulation, order or agreement), commence and thereafter diligently
         prosecute to completion, all such Remedial Work. All Remedial Work
         shall be performed by qualified contractors. All costs and expenses of
         such Remedial Work shall be paid by Tenant, including, without
         limitation, Landlord's reasonable attorneys' fees and costs incurred in
         connection with monitoring or review of such Remedial Work. In the
         event Tenant shall fail to timely prosecute to completion such Remedial
         Work, Landlord may, but shall not be required to, cause such Remedial
         Work to be performed and all costs and expenses thereof, or incurred in
         connection therewith, shall become due from the Tenant within ten (10)
         days after Notice thereof, and shall be considered as Additional Rent.

         G. The Tenant agrees it will not make any structural changes to the
Leased Premises without the written approval of the Landlord, which shall not be
unreasonably withheld or delayed.

         H. The Tenant agrees it will not place fixtures, equipment, or material
of any kind in the Leased Premises, the weight of which may exceed the floor
load capacity as specified in the Tenant Plans.

         I. Tenant shall at no time permit any asbestos containing material to
be used on, under, or about the Leased Premises.

                                  ARTICLE IX
                           LANDLORD INDEMNIFICATION
                           ------------------------

         A. Except as otherwise provided for herein, Landlord agrees to
indemnify and save harmless Tenant, Tenant's successors and assigns, and
Tenant's present and future officers, directors, employees, and agents
(collectively TENANT INDEMNITEES) against any and all claims, demands, damages,
costs, and expenses, arising from the operations of the Landlord in the
Building, or from the construction of improvements to any other portion of the
Building, or from any breach or default on the part of Landlord in the
performance of any covenant or agreement on the part of Landlord to be performed
pursuant to the terms of this Lease, or from any act of negligence of Landlord,
its agents, contractors, servants, and employees in or about the Leased Premises
and the Building. In case of any action or proceeding brought against Tenant
Indemnities by reason of any such claim, upon Notice from Tenant, Landlord
covenants to defend such action or proceeding by counsel, competent in the
Tenant's reasonable judgement. To the extent not expressly prohibited by law,
Landlord releases Tenant Indemnitees, from, and waives all claims to damages to
person or property, sustained by the Landlord and/or the Building resulting
directly or indirectly from fire or other casualty, because of existing or
future conditions, defects, matters or things in the Leased Premises or any part
thereof; or from any equipment or appurtenances therein or from any accident in
or about the Leased Premises or from any act by any of Tenant's employees,
agents or servants, EXCEPT in the event the damages are caused by the negligence
or wrongful intentional acts of the Tenant Indemnitees.

         B. Landlord agrees to indemnify and save harmless Tenant Indemnitees
from and against any and all liabilities, penalties, fines, forfeitures,
demands, damages, losses, claims, causes of action, suits, judgements, and costs
and expenses incidental thereto (including cost of defense, settlement,
reasonable attorneys' fees, reasonable consultant fees, and reasonable expert
fees), which Tenant Indemnities may hereafter suffer or incur, be responsible
for or disburse as a result of any liabilities directly or indirectly caused by
or arising out of any Hazardous Materials existing on or about the Leased
Premises, the Building and/or the Site, but only to the extent that any such
existence is caused by Landlord's activities on the Leased Premises, the
Building and/or the Site. This provision shall survive termination of the Lease.

                                    ARTICLE X
                               LANDLORD'S MORTGAGE
                               -------------------

From time to time before or after the execution of this Lease, and before the
termination of the Term thereof, the Landlord may execute a mortgage or trust
deed in the nature of a mortgage of Landlord's interest in the Building. In such
event:

         A. This Lease and all rights of Tenant are subject and subordinate to
         any mortgage or mortgages, blanket or otherwise, which do now or may
         hereafter affect the Building, and to any and all renewals,
         modifications, consolidations, replacements, and extensions thereto. It
         is the intention of the parties that this provision be self-operative
         and that no further instrument shall be required to effect such
         subordination of this Lease. Tenant shall, however, upon demand at any
         time or times, execute, acknowledge, and deliver to Landlord, within
         ten (10) days after written request by Landlord, without expense to
         Landlord, any and all instruments that may be necessary or proper to
         subordinate this Lease, and all rights of Tenant hereunder to any such
         mortgage or to confirm or evidence such subordination; provided,
         however, the mortgagee shall agree to enter into a non-disturbance
         agreement with the Tenant, which agreement shall state that provided
         the Tenant is in

                                      16
<PAGE>

         full compliance with the terms and provisions of this Lease and has not
         committed an Event of Default (as defined hereinafter), the Lease shall
         remain in full force and effect and the possession of the Leased
         Premises by the Tenant shall not be disturbed.

         B. Landlord agrees promptly to notify Tenant of the placing of any
         mortgage or trust deed against the Site or the Building, and Tenant
         agrees in the event of any act or omission by Landlord which would give
         Tenant the right to terminate this Lease, or to claim a partial or
         total eviction, Tenant shall not exercise any such right until it has
         notified in writing the holder of any mortgage which at the time shall
         be a lien on the Building, of such act or omission, and such holder is
         provided with a reasonable time not exceeding thirty (30) days to cure
         any such default.

         C. Tenant covenants and agrees, in the event any proceedings are
         brought for the foreclosure of any such mortgage, to attorn to the
         purchaser upon any such foreclosure sale, if so requested to do so by
         such purchaser, and to recognize such purchaser as the Landlord under
         this Lease, provided Tenant is furnished with a non disturbance
         agreement, within thirty (30) days of the said purchase. Tenant agrees
         to execute and deliver, at any time and from time to time, upon the
         request of Landlord or any holder of such mortgage or such purchaser,
         any instrument which, in the reasonable judgment of such requesting
         party, may be necessary or appropriate in any such foreclosure
         proceeding or otherwise to evidence such attornment. In the event of
         such foreclosure, the Tenant's right to possession and quiet enjoyment
         shall not be disturbed provided it is in full compliance with all the
         material terms and conditions of this Lease.

         D. Any reference herein to the words "foreclosure, foreclosure sale,
         and/or foreclosure proceeding" shall be interpreted to include a
         conveyance by deed in lieu of foreclosure.

                                   ARTICLE XI
                          RIGHTS RESERVED TO LANDLORD
                          ---------------------------

Landlord shall have the following rights exercisable after Notice to Tenant
(except in the event of an emergency, when prior Notice will not be required)
and without liability to Tenant for damage or injury to the property, person, or
business (all claims for damage being hereby released) and without effecting an
eviction (constructive or otherwise) or disturbance of Tenant's use or
possession or giving rise to any claim for set-offs or abatement of Rental:

         A. To change the name of the Building upon three (3) month's prior
         written Notice;

         B. To install and maintain signs on the exterior and interior of the
         Building;

         C. To have passkeys to the Leased Premises;

         D. To enter the Leased Premises at reasonable business hours, after
         reasonable Notice, to make inspections, to exhibit the Leased Premises
         to purchasers, mortgagees or others, or for other reasonable purposes,
         and in the last six (6) months of the Term, to exhibit the Leased
         Premises to prospective tenants;

         E. At any reasonable time or times and during business hours, to
         decorate and to make, at its own expense, repairs, alterations,
         additions, and improvements, structural or otherwise, in and to the
         Building, and to perform any acts related to

                                       17
<PAGE>

         The safety, protection, or preservation thereof, and during such
         operations to take into and through the Leased Premises, or any part of
         the Building, all materials and equipment required and to close or
         temporarily suspend operation of entrances, doors, corridors, or other
         facilities, provided such work does not substantially interfere with
         the Tenant's ability to conduct its business, or make the Leased
         Premises any less desirable; and

         F. To enter upon the Leased Premises at reasonable times, after
         reasonable Notice, for any reasonable purposes contemplated herein.

                                   ARTICLE XII
                        DAMAGE BY FIRE OR OTHER CASUALTY
                        --------------------------------

         A. If the Leased Premises or the Building shall be damaged by fire or
other cause and if it appears in the reasonable opinion of the Landlord's
architect that the Leased Premises and/or the Building may be repaired or
restored within one hundred fifty (150) days after such damage, and should the
mortgagee of the Building elect to make sufficient insurance proceeds available
for the costs of the repair and restoration, then Landlord shall commence to
restore the Leased Premises and the Building as soon as reasonably possible and
complete such repair or restoration with reasonable promptness. Based upon the
architect's opinion and the mortgagee's decision to make the insurance proceeds
available, Landlord shall make an election to restore or not to restore within
forty five (45) days after the date of the casualty, and shall so notify the
Tenant in writing. If the Landlord elects not to restore, this Lease shall
forthwith terminate upon the date of said damage. Should no Notice be received
from the Landlord within the forty five (45) day period, it shall conclusively
be presumed that the Landlord has elected to restore the Leased Premises and the
Building.

         B. Notwithstanding anything to the contrary herein contained, Landlord
shall have no duty pursuant to this Article XII to repair or restore any Tenant
Alterations to the Leased Premises made after the Commencement Date; unless the
Tenant has notified the Landlord in writing, prior to the fire or other
casualty, that it desires the Landlord to add certain specified Tenant
Alterations to the fire and extended coverage insurance policies of the Landlord
and the Tenant has paid to the Landlord the actual cost of any additional
insurance premiums resulting therefrom. If, at the time of the casualty, Tenant
wants any other or additional repairs, restorations, additions, or alterations,
and if Landlord consents thereto, which consent shall not be unreasonably
withheld, the same shall be done by Landlord at the Tenant's expense.

         C. Rental shall abate beginning with the date of the damage causing the
Leased Premises to be untenantable and ending with the date when the Leased
Premises are again rendered tenantable, however, such abatement shall be limited
to the ratio the untenantable portion of the Leased Premises bears to the entire
Leased Premises, should only a portion of the Leased Premises be untenantable;
provided, however, if the damage had been caused by the intentional act or
neglect of the Tenant which results in one or more of the insurance companies
providing the fire and extended coverage on the claim asserting a defense to the
payment of all or a material part of the claim resulting from the casualty,
then, in such event, Rental shall not abate and the Tenant shall be obligated to
continue the payment of Rental during the period the Leased Premises or any part
thereof is untenantable.

         D. Notwithstanding any provisions herein to the contrary, in the event
the Leased Premises or the Building are not restored or rendered tenantable
within one hundred fifty (150) days after the casualty, the Tenant shall have
the right to cancel and terminate this Lease upon a prior thirty (30) day
written Notice of the Landlord.

                                  ARTICLE XIII
                                 EMINENT DOMAIN
                                 --------------

         A. If the entire Building shall be taken by any public authority under
the power of eminent domain, then the Term of this Lease shall cease as of the
day possession shall be taken by such public authority, and the Rental shall be
paid up to that date with a proportionate refund by Landlord of such Rental as
shall have been paid in advance. The Landlord shall provide the Tenant with
Notice of a taking within thirty (30) days after it receives formal notice from
the said public authority.

         B. If a material portion of the floor area of the Leased Premises shall
be taken under the power of eminent domain, Landlord and the Tenant shall each
have the right to terminate this Lease, by Notice in writing to the other on or
before the day of surrendering possession to the public authority, and Rental
shall be paid or refunded as of the date of termination. In the event this Lease
remains in effect, all of the terms herein provided shall continue in effect
except that the Rental shall be equitably abated, and Landlord shall make all
necessary repairs or alterations to the Leased Premises and the Building so as
to constitute the remaining premises a complete architectural unit.

         C. All damages awarded for such taking under the power of eminent
domain, whether for the whole or a part of the Leased Premises, shall be the
property of Landlord, whether such damages shall be awarded as compensation for
diminution in value of the leasehold or to the fee of the Building. However, the
Tenant shall be entitled to seek separate damages for any such taking so long as
the same does not diminish or reduce the Landlord's award.

                                  ARTICLE XIV
                           ASSIGNMENT AND SUBLETTING
                           -------------------------

         A. Tenant shall not assign nor in any other way transfer this Lease or
any interest therein, nor sublet the Leased Premises or any part or parts
thereof, nor permit occupancy by anyone with, through, or under it, without the
previous written consent of the Landlord, which consent shall not be
unreasonably withheld or delayed. Consent by the Landlord to one or more
assignments or subletting of this Lease or the Leased Premises shall not operate
as a waiver of Tenant's rights as to any subsequent assignments or subletting.
The Tenant specifically understands and agrees that any assignment or sublease
shall in no way release (unless by written agreement) the Tenant of any of its
obligations and covenants under this Lease, nor should said assignment or
sublease be construed or taken as a waiver of any of the Landlord's rights or
remedies hereunder against or as relating to the Tenant. It is the specific
understanding and intention of the parties that in the event the Tenant's
interest herein is assigned or sublet either through the provisions of this
Article, by operation of law or otherwise, the Tenant shall not monetarily
benefit from an increase in the Rental or other considerations paid by the
assignee or subtenant over and above the Rental provided for in this Lease. In
the event the terms of the assignment or sublease provide for an increase in
Rental over and above the rental provided for herein, or in the event the Tenant
receives, or is entitled to receive, a bonus or consideration from the assignee
or subtenant in consideration of said assignment or sublease, such increased
Rental, bonus, or consideration shall be paid directly to the Landlord by either
the Tenant and/or the assignee or sublessee, as the case may be; however, Tenant
shall have the right, prior to the payment to the Landlord of the increased
Rental, bonus, or consideration to deduct therefrom any and all costs incurred
by Tenant in acquiring such assignee or sublessee, including but not limited to
leasing commissions, advertising costs, and changes or

                                       19

Improvements to the Leased Premises.

         B. Notwithstanding the above, the Tenant has the right to assign or
sublease to a corporation which is the parent or subsidiary of or is controlled
by Tenant, or to a corporation resulting from any reorganization or merger to
which Tenant or its parent or any of its subsidiaries or any corporation
controlled by it is a party; provided further, however, in the event of any
assignment or sublease by Tenant, Tenant shall remain primarily liable and
responsible for the faithful performance of this Lease, the use of the Leased
Premises shall be substantially the same, and the Tenant gives the Landlord
written Notice of all particulars of the assignment or sublease.

                                   ARTICLE XV
                                    REMEDIES
                                    --------

<PAGE>


         filing or notice of lien to Landlord; and if the Tenant has commenced

         considered to have committed an Event of Default provided it diligently
         pursues said remedial activity for a reasonable period of time as may
         be required, but in no event more than sixty (60) days.

         B. Upon the occurrence of any one (1) or more of the above Events of
Default or any other Event of Default specified elsewhere in this Lease, and
after the expiration of the cure period provided, if any, then upon written
Notice from Landlord to Tenant, the Landlord may elect to either (a) terminate
the Lease, or (b) terminate the rights of the Tenant to possession of the Leased
Premises only without terminating the Lease. Upon termination of the Lease, or
upon any termination of the Tenant's right to possession without termination of
the Lease, Tenant shall surrender possession and vacate the Leased Premises
immediately, and deliver possession thereof to Landlord, and Tenant hereby
grants to Landlord the full and free right, without further demand or Notice of
any kind to Tenant (except as herein expressly provided), to enter into and upon
the Leased Premises in such event, with due process of law, and to repossess the
Leased Premises as Landlord's former estate and to expel or remove Tenant and
any others who may be occupying or within the Leased Premises, and remove
Tenant's personal property, signs, and other evidences of tenancy, without being
deemed in any manner guilty of trespass, eviction, or forcible entry or
detainer, without incurring any liability for any damage resulting therefrom,
and without relinquishing Landlord's rights to Rental for the entire balance of
the Term, or from any other obligations under this Lease, or any other right
given to Landlord by operation of law.

         C. Upon termination of the Lease, Landlord shall be entitled to receive
as damages all Rental (including Repayments) and other sums due and payable by
Tenant on the date of the termination, plus (a) the present value of the Rental
and other sums provided herein to be paid by Tenant for the rest of the Term
less the fair rental value of the Leased Premises, each based upon a discount
rate of nine percent (9%), plus (b) the cost of performing any other covenants
to be performed by Tenant, and (c) the cost of attorneys' fees and court costs
incurred by the Landlord, if any, in enforcing the rights of the Landlord, less
any Repayments received by Landlord.

         D. If Landlord elects to terminate the Tenant's right to possession
only without terminating the Lease, Landlord shall be entitled to receive as
damages (a) all Rental and other sums due and payable by Tenant on the date of
the termination (including Repayments), plus (b) all Rental and other sums as
such become due and payable thereafter for the rest of the Term, plus (c) the
cost of performing any other covenants to be performed by Tenant under the terms
and provisions of this Lease, plus (d) the cost of reasonable attorneys' fees
and court costs incurred by the Landlord, if any, in enforcing the rights of the
Landlord, less any Repayments received by Landlord.

         E. Upon termination of the Lease, or if in the event the Landlord
elects to terminate the Tenant's right to possession and not terminate the
Lease, the Landlord

                                      21
<PAGE>

shall have the obligation to use reasonable efforts to relet the Leased
Premises, however, Landlord shall not be deemed to have failed to use such
reasonable efforts by reason of the fact that Landlord has leased or sought to
lease other vacant premises owned by Landlord (or Landlord's Beneficiaries), in
preference to reletting the Leased Premises. Landlord may relet all or any part
of the Leased Premises for such reasonable rental and upon such terms as shall
be reasonably satisfactory to Landlord (including the right to relet the Leased
Premises for a term greater or lesser than that remaining on the Term of this
Lease, and the right to relet the Leased Premises as a part of a larger area or
a smaller area, and the right to change the character or use made of the Leased
Premises). For the purpose of such reletting, Landlord may decorate or make any
repairs, changes, cleaning, painting, alterations, or additions in or to the
Leased Premises, and may further pay for customary leasing brokers' commissions,
reasonable market rent concessions to a new tenant or tenants, and reasonable
attorneys' fees that may be necessary to induce or procure the replacement
tenant. If the Leased Premises are relet and a sufficient sum shall not be
realized from the collection of the rental of such reletting, after paying all
the expenses of such reletting as referred to hereinabove, to satisfy the
remaining Rental and other charges due from the Tenant for the remainder of the
Term, Tenant shall pay to the Landlord on demand any such deficiency, within
twenty (20) days after demand.

         F. In the event of any uncured Event of Default hereunder by Tenant,
including but not limited to, Tenant's failure to obtain insurance, make
repairs, or satisfy lien claims, Landlord may, but is not obligated to, with
Notice to the Tenant, cure the Event of Default for the account of and at the
expense of Tenant. Any such sum of money paid by Landlord, plus ten percent
(10%), shall be due and payable by the Tenant to the Landlord, as Additional
Rent, and shall be assessed annual interest thereon at the rate of three percent
(3%) in excess of the then current prime rate of interest from time to time
charged by the First National Bank of Chicago, or twelve percent (12%) per
annum, whichever is greater, from the date of payment by the Landlord.

         G. If the Landlord or the Tenant are compelled to incur any expense in
instituting or prosecuting any action or proceeding in law or in equity to
enforce any of the rights and obligations hereunder or to defend any action
brought by the Tenant or the Landlord, the losing party in such actions shall
pay to the prevailing party, the expenses incurred, including but not limited to
reasonable attorneys' fees and court costs, with interest thereon at the rate of
three percent (3%) in excess of the then current prime rate of interest from
time to time charged by the First National Bank of Chicago per annum, or twelve
(12%) per annum, whichever is greater, commencing on the date of decision by the
trial court. Any sums hereunder due from the Tenant to the Landlord shall be
considered as Additional Rent. In the event of any such actions or proceedings
arising out of this Lease, both parties agreed to waive right of trial by jury.

         H. No remedy herein or otherwise conferred upon or reserved to Landlord
shall be considered to exclude or suspend any other remedy, but the same shall
be cumulative and shall be in addition to every other remedy given hereunder now
or hereafter existing at law or in equity or by statute, and every power and
remedy given by this Lease to Landlord may be exercised from time to time and as
often as occasion may arise or as may be deemed expedient. No delay or omission
of Landlord to exercise any right or power arising from any breach of the Lease
by the other shall impair any such right or power or shall be construed to be a
waiver of any such breach or any acquiescence therein.

         I. The monthly installments of Rental are due on the 1st day of each
month. Any other charges are due within thirty (30) days of written Notice
thereof. All Rental and/or other sums due from Tenant to Landlord which are then
unpaid when due, shall be

                                       22
<PAGE>


assessed interest thereon at the rate of three percent (3%) in excess of the
then current prime rate of interest from time to time charged by the First
National Bank of Chicago per annum, or twelve percent (12%) per annum, whichever
is greater, and said sum shall be payable by Tenant as Additional Rent.

         J. The provisions of this Article shall survive the termination of this
Lease.

                             SURRENDER OF POSSESSION
                             -----------------------

         A. At the expiration of the Term, whether by lapse of time or
otherwise, Tenant shall surrender the Leased Premises in good condition and
repair, reasonable wear and tear and loss by fire or other unavoidable casualty
excepted.

         B. In the event Tenant remains in possession of the Leased Premises
after the expiration of the Term, without the execution of a new lease or the
exercise of the provisions of Article XXII, it shall be deemed to be occupying
the Leased Premises as a tenant at sufferance from month to month, at Two
Hundred Percent (200%) of the Rental and other charges due from Tenant paid or
payable during the last month of the Term, subject to all the other conditions,
provisions, and obligations of this Lease insofar as the same are applicable to
a month to month tenancy unless otherwise agreed to in writing by the parties.
Tenant shall also pay to the Landlord all consequential damages sustained by
Landlord on account of such holdover including, but not limited to, loss of
rental from prospective tenants for the Leased Premises. The provisions of this
Article XVI B shall not operate as a waiver by Landlord of any right of
re-entry, or other remedies available to Landlord hereinabove provided or by
operation of law.

         C. Upon the expiration of the Term, whether by the lapse of time or
otherwise, if Landlord so requests in writing, Tenant shall promptly remove all
personal property and those Tenant Alterations not affixed to the realty, and
repair any damage occasioned by such removals at Tenant's expense; and if in
default thereof, Landlord may effect such removals and repairs, and Tenant shall
pay Landlord the cost of such removals and repairs, plus ten percent (10%), with
interest at the rate of three percent (3%) in excess of the then current prime
rate of interest from time to time charged by the First National Bank of Chicago
per annum, or twelve percent (12%) per annum, whichever is greater, commencing
on the date of payment thereof, and same shall be due and payable by the Tenant
within ten (10) days after Notice.

                                    NOTICES
                                    -------

         A. Whenever under this Lease a provision is made for notice of any kind
(hereinafter referred to as NOTICE), the Notice shall be in writing, and signed
by or on behalf of the party giving or making the Notice, and shall be given to
the Party at its address and/or fax number set forth below or such other address
and/or fax number as the party may later specify for that purpose by Notice to

         number specified below and confirmation of complete receipt is received
         by that transmitting party during normal business hours or on the next
         business day if not confirmed during normal business hours;

         prepaid, two (2) business days after it is posted with the United

         B. If any Notice is sent by fax, the transmitting party shall send a
duplicate copy of the Notice to the other party by regular mail. In all events,
however, any Notice sent by fax transmission shall govern all matters dealing
with delivery of the Notice, including the date on which the Notice is deemed to
have been received by the other party.

         C. The provisions above governing the date on which a Notice is deemed
to have been received by a party to this Lease shall mean and refer to the date
on which a party to this Lease, and not its counsel or other recipient to which
a copy of the Notice may be sent, is deemed to have received the Notice.

         D. If Notice is tendered under the provisions of this Lease and is

considered to have been given and shall be effective as of the date of the
refusal. The contrary notwithstanding, any Notice given to a party in a manner
other than that provided in this Lease, that is actually received by that party,
shall be effective with respect to said party on receipt of the Notice.

                         AMERICANS WITH DISABILITIES ACT
                         -------------------------------

         Notwithstanding anything to the contrary contained in this Lease,
Landlord is and shall be solely responsible for ensuring that at the time of the
Commencement Date, the Leased Premises and the Building are in full compliance
with Title III of the Americans With Disabilities Act (42 U.S.C. SS. 12101 et
seq. - hereinafter referred to as ADA), and

all regulations pursuant thereto (the REGULATIONS). Landlord hereby indemnifies,
saves, and holds harmless Tenant from and against any and all claims, demands,
causes of action, suits, losses, costs, and expenses (including, without
limitation, attorneys' fees and litigation costs), damages, penalties and fines
asserted against, suffered or incurred by, Tenant in any way relating to or
arising from, in whole or in part, an actual or asserted claim that the Leased

responsible for the cost of any major structure changes which may be required to
place the Building in full compliance with said amended ADA or Regulations;

                                   ARTICLE XIX
                                     GENERAL
                                     -------

         A. Nothing contained herein shall be deemed or construed by the parties
hereto, nor by any third party, as creating the relationship of principal and
agent or of partnership or of joint venture between the parties hereto, it being
understood and agreed that neither the method of computation of Rental nor any
other provision contained herein, nor any acts of the parties hereto shall be
deemed to create any relationship between the parties hereto other than the
relationship of the landlord and tenant. Whenever herein the singular number is
used, the same shall include the plural, and the masculine gender shall include
the feminine and neuter genders.

         B. The various rights and remedies herein contained and reserved to
each of the parties shall not be considered as exclusive of any other right or
remedy of such party, but shall be construed as cumulative and shall be in
addition to every other remedy now or hereafter existing at law, in equity, or
by statute. No delay or omission of the right to exercise any power by either
party shall impair any such right or power, or shall be construed as a waiver of
any Event of Default or as acquiescence therein. One or more waivers of any
covenant, term, or condition of this Lease by either party shall not be
construed by the other party as a waiver of a subsequent breach of the same
covenant, term, or condition. The consent or approval by either party to or of
any act by the other party of a nature requiring consent or approval shall not
be deemed to waive or render unnecessary consent to or approval of any
subsequent similar act, and specifically the acceptance of a late payment of
Rental by the Landlord, shall not constitute a waiver of the obligation of the
Tenant to make all future payments in a timely manner as provided for herein.

         C. The laws of the State of Illinois shall govern the validity,
performance, and enforcement of this Lease. The invalidity or unenforceability
of any provision of this Lease shall not affect or impair any other provisions.

         D. The headings of the several articles contained herein are for
convenience only and do not define, limit, or construe the contents of such
articles.

         E. The covenants, agreements, and obligations herein contained shall
extend to, bind and inure to the benefit not only of the parties hereto but
their successors and assigns, with the exceptions as stated herein.

         F. Whenever a period of time is herein provided for Landlord or Tenant
to do or perform any act or thing, neither shall be liable or responsible for
any delays due to

                                      25
<PAGE>

strikes, riots, acts of God, shortages of labor or materials, national
emergency, acts of a public enemy, governmental restrictions, laws or
regulations, or any other cause or causes whether similar or dissimilar to those
enumerated, beyond its reasonable control.

         G. No payment by Tenant or receipt by Landlord of a lesser amount than
the Rental herein stipulated or other charges shall be deemed to be other than
on account of the earliest stipulated amount, nor shall any endorsement or
statement on any check or any letter accompanying any check or payment as Rental
be deemed an accord and satisfaction, and Landlord may accept such check or
payment without prejudice to Landlord's right to recover the balance of such
Rental or other charges or pursue any other remedy in this Lease provided.

         H. This Lease and the Exhibits, attached hereto and forming a part
hereof, set forth all the covenants, promises, agreements, conditions, and
understandings between Landlord and Tenant concerning the Leased Premises, and
there are no covenants, promises, agreements, conditions, or understandings,
either oral or written, between them other than as are herein set forth. Except
as herein otherwise provided, no subsequent alteration, amendment, change, or

to pay; and each of the parties agree to indemnify and hold harmless the other
against all liabilities arising from any such claim other than from CB
Commercial and Stein & Company, including, without limitation, the cost of
counsel fees and costs in connection therewith.

         J. So long as the Tenant shall observe and perform the covenants and
agreements binding on it hereunder, Tenant shall at all times during the Term
hereof, peacefully and quietly have and enjoy the possession of the Leased
Premises, and the Landlord shall and will warrant and defend the Leased Premises
on behalf of the Tenant against any and every person claiming the whole or part
thereof.

         K. Tenant shall from time to time, within ten (10) days after written
request by Landlord, execute, acknowledge, and deliver to Landlord an Estoppel

                              DISPUTE RESOLUTION
                              ------------------

         A. The parties shall attempt in good faith to resolve all disputes
promptly by negotiation.  Any party may give the other party written Notice of
any dispute not

                                      26
<PAGE>

resolved in the normal course of business. Senior executives of both parties
shall meet at a mutually acceptable time and place within ten (10) days after
delivery of such Notice, and thereafter as often as they reasonably deem
necessary, to exchange relevant information and to attempt to resolve the
dispute. If the matter has not been resolved within thirty (30) days from the
referral of the dispute to senior executives, or if no meting of senior
executives has taken place within fifteen (15) days after such referral, either
party may initiate mediation as provided hereinafter. All negotiations pursuant
to this clause are confidential and shall be treated as compromise and
settlement negotiations for purposes of the Federal Rules of Evidence and State
rules of evidence.

         B. In the event that any dispute arising out of or relating to this
Lease is not resolved in accordance with the procedures provided in Section A
above, the dispute shall be submitted to mediation with American Arbitration
Association (AAA), in Chicago, Illinois. If the mediation process has not
resolved the dispute within thirty (30) days of the submission of the matter to
mediation, or such longer period as the parties may agree, then the dispute
shall be decided by arbitration as set forth below.

         C. All claims, disputes, and other matters in question not resolved by
mediation, including whether either of the parties are responsible for the
payment of fees, costs and attorneys fees (hereinafter collectively referred to
as the CONTROVERSY) shall be decided by binding arbitration by the AAA in
accordance with the Arbitration Rules of the AAA then in effect. This agreement
to submit to binding arbitrate shall be specifically enforceable under the
prevailing arbitration law of any court of competent jurisdiction. Notice of
demand for arbitration must be filed in writing with the other party to this
Lease and with the AAA. The demand must be made within a reasonable time after
the Controversy has arisen. In no event may a demand for arbitration be made if
the Controversy would be barred by the applicable statute of limitations.

                            RIGHT OF FIRST REFUSAL
                            ----------------------

         A. Providing the Tenant has not committed an uncured Event of Default,
the Landlord hereby grants to the Tenant a right of first refusal to lease any
remaining space in the Building. When the Landlord has received a bona fide
written proposal signed by a third party to lease any space in the Building
acceptable to the Landlord, the Landlord shall first send a Notice to the Tenant
including a copy of the proposal, which shall include but not limited to, the
location in the Building of the offered space (herein FIRST REFUSAL PREMISES),
its rentable square feet, the rental, the term, tenant improvement allowances
and rent allowances if any, the commencement and termination dates, rights to
expansion space, renewal options, and any other special terms or conditions the
Landlord deems pertinent. This Notice and copy of the proposal shall hereinafter
be referred to as FIRST REFUSAL NOTICE. The Tenant shall have fifteen (15) days
thereafter to elect, in writing, to agree to lease the First Refusal Premises
upon the provisions set forth in the First Refusal Notice. In the event the
Tenant fails to exercise its rights hereunder by notifying the Landlord in
writing within the fifteen (15) day period the Landlord shall have the right to
enter into a lease with the said thirty party described in the First Refusal
Notice but only upon substantially the same economic terms set forth therein. If
the Landlord substantially and materially changes or alters the economic terms
of the lease to the third party, the Landlord shall give the Tenant a new First
Refusal Notice, and the Tenant shall again have the same rights as provided for
above.

         B. In the event the Tenant exercises its right of the first refusal
provided in this Article XXI, the Landlord shall thereupon prepare a lease
amendment to this Lease based upon the terms of said First Refusal Notice. If
the Landlord and the Tenant, both

                                      27
<PAGE>

acting reasonably and fairly, cannot agree upon the terminology of the said
amendment within thirty (30) days after the delivery to the Tenant of the
initial draft of the amendment, then the Landlord may elect, upon written Notice
to the Tenant, to terminate this right of first refusal as to that particular
First Refusal Premises and lease the First Refusal Premises to the third party
upon the same economic terms and provisions as in the First Refusal Notice.

         C. The Tenant's refusal or failure to exercise its rights under this
Article XXI as to a particular set of terms for a particular First Refusal
Premises, or the inability of the Tenant to agree on the terminology of a lease
agreement, shall not terminate this right of first refusal as to any other
spaces or the same space being offered for lease thereafter.

         D. After the exercise of the rights provided in this Article XXI, and
the entry by both parties into a lease agreement for the lease of the First
Refusal Premises, the term Leased Premises, as applied in this Lease, shall also
apply to the First Refusal Premises.

         E. This Right of First Refusal shall not apply to any space in the
Building being leased by Motorola, Inc. and/or any of its subsidiaries or
affiliates.

                                  ARTICLE XXII
                                OPTION TO REVIEW
                                ----------------

         Provided the Tenant has not committed an uncured Event of Default, the
Tenant shall have the right to renew this Lease and lease the Leased Premises
for one (1) five (5) year period, hereinafter referred to as the EXTENDED TERM,
upon the same terms and conditions set forth herein with the following
exceptions:

         A. The monthly Fixed Rent to be paid by the Tenant during the first
         year of the Extended Term shall be the greater of the following:

                  (a) Forty Six Thousand Nine Hundred and Sixty Five and 23/100
                  Dollars ($46,965.23); or

                  (b) Thirty-Eight Thousand Five Hundred and Forty Six and
                  53/100 Dollars ($38,546.53), plus that sum determined by
                  multiplying the percentage increase of the PRICE INDEX between
                  the month of April 1997 and April 2004 times Thirty-Eight
                  Thousand Five Hundred and Forty Six and 53/100 Dollars
                  ($38,546.53).

         B. The Fixed Rent during the second (2nd) year of the Extended Term,
         and in each year thereafter, shall be increased by two and one-half
         Percent (2.5%) of the preceding year's Fixed Rent.

         C. The word "year" as used in this Article shall mean the period from
         July 1 to June 30.

         D. The Price index means the consumer price index published by the
         Bureau of Labor Statistics of the United States Department of Labor,
         U.S. City Average, All Items and Major Group Figures for Urban Wage
         Earners and Clerical Workers (1982-84=100). If a substantial change is
         made in the manner of computing the Price Index, then the Price Index
         will be adjusted to the figures that would have been used had the
         manner of computing the Price Index be the same as that in effect as of
         the Commencement Date.

                                       28
<PAGE>


         If the Price Index is not available, a reliable governmental or other
         nonpartisan publication evaluating the information used in determining
         the consumer price index shall be applied for the purposes of this
         Article XXII.

         E. To exercise this renewal option, the Tenant must give the Landlord
         written Notice, on or before July 1, 2003.

         F. Upon the exercise of this renewal option, the word Term as defined
         in this Lease shall also apply to the Extended Term, and the term
         Termination Date shall be defined as the last date of the Extended
         Term.

         G. All other terms and conditions of this Lease shall be in full force
         and effect during the Extended Term, including the obligation to pay
         Additional Rent.

         H. This renewal option shall be exercised only as to all the Leased
         Premises leased by the Tenant at the time of the Notice.

                                  ARTICLE XXIII
                            SECURITY LETTER OF CREDIT
                            -------------------------

         A. Tenant, contemporaneously with the exception of this Lease, shall
deposit with Landlord, an unconditional and irrevocable letter of credit in
favor of the Landlord in the amount of Five Hundred Thousand Dollars ($500,000),
hereinafter referred to as the L/C DEPOSIT. The L/C Deposit shall be held by
Landlord as security for the faithful performance by Tenant of all of the terms,
covenants, and conditions of this Lease by said Tenant to be kept and performed.

         B. The form, provisions and terms of the L/C Deposit shall be as
follows:

         (a) The L/C Deposit shall be drawn on a bank approved by the Landlord
         (hereinafter referred to as the L/C BANK), which approval will not be
         unreasonably withheld or delayed.

         (b) The expiration date of the L/C Deposit shall be April 1, 2002. If
         the expiration date of the L/C Deposit is prior to April 1, 2002, the
         Tenant must supply a new L/C Deposit, extending the expiration date for
         a period of at least one (1) year, thirty (30) days prior to the
         expiration date. Failure on the part of the Tenant to supply such new
         L/C Deposit on a timely basis, shall be considered as an Event of
         Default of this Lease.

         (c) The amount of the L/C Letter shall decrease One Hundred Thousand
         Dollars ($100,000) annually on the anniversary date of the Commencement
         Date, as follows:

                  (1)      April 1, 1998 - $400,000
                  (2)      April 1, 1999 - $300,000
                  (3)      April 1, 2000 - $200,000
                  (4)      April 1, 2001 - $100,000
                  (5)      April 1, 2002 -    00

         (d) The Landlord shall have the right to draw on the L/C Letter if the
         Tenant has committed an Event of Default, and the cure period (if any)
         expired without appropriate remedial actions by the Tenant, and as a
         result thereof, the Landlord elected to either terminate the Lease or
         terminate the Tenant's right to possession of the Leased Premises
         without terminating the Lease (pursuant to Article XV B). The

                                      29
<PAGE>


         L/C Bank shall pay to the Landlord the amount of the L/C Letter when it
         is personally served with a letter from LAMCO, or from such other agent
         as Landlord may from time to time hereafter designate in writing to the
         L/C Bank, which shall contain the following wording:

                  "Allscrips Pharmaceuticals, Inc. ("Allscrips") has committed
                  an Event of Default, pursuant to the provisions of a Lease
                  agreement dated October __, 1996, and any cure period as
                  provided in the Lease Agreement has expired without Allscrips
                  remedying the Default, and the Landlord has terminated the
                  Lease Agreement or terminated Allscrips' right to possession
                  of the Leased Premises."

         (e) The form and the remainder of the working of the L/C Letter shall
         be subject to the approval of the Landlord, which approval will not be
         unreasonably withheld or delayed.

         C. At any time during the Term, should either one of the two events
occur, the Landlord shall return the L/C Letter to the Tenant and no further
security shall be required of the Tenant:

         (a) An initial public offering of the stock of the Tenant which results
         in net proceeds, after commissions and expenses, of Twenty Five Million
         Dollars ($25,000,000) or more being added to the working capital of the
         Tenant; or

         (b) The merger of the Tenant into a company which, prior to the merger,
         has a net worth of Twenty Million Dollars ($20,000,000) or more.

Site requires the prior written approval of the Declarants, or of the
Association in the event the rights of Declarants have been transferred or
assigned to the Association. Notwithstanding anything herein to the contrary,
Declarants reserve the right to change the use and zoning of any Building Site
Declarants own, subject only to approval by the Village.

required replacements.

                  6. TIME. All landscaping on each Building Site shall be
completed within sixty (60) days after occupancy of, or completion of the major
or primary building thereon, whichever event first occurs. The time for
completion may be extended by Declarants if there are delays caused by adverse
weather conditions or by other causes beyond reasonable control. If any Owner
fails to undertake and complete its landscaping within the time limit set forth
above, Declarants may, at their option, after giving such Owner ten (10) days'
prior written notice (unless within said ten (10) day period the Owner of said
Building Site shall proceed and thereafter pursue with diligence the completion
of such landscaping), undertake and complete the landscaping of such Building
Site in accordance with the approved landscaping plan therefor. If Declarants

a lien against the Building Site and may be enforced as set forth in Section
VIII.A.7. hereof.

                  7. LETTER OF CREDIT. In addition to the foregoing, each Owner
shall deliver to Declarants no later than ten (10) days subsequent to approval
of the landscaping plans by Declarants, an irrevocable unconditional letter of
credit in form satisfactory to Declarants, issued by a commercial bank or
savings and loan association approved by Declarants, in the amount of the

complete the same. Upon completion of the landscaping by Owner in accordance
with the approved plans, the letter of credit shall be promptly returned by
Declarants to Owner. Notwithstanding the foregoing, an Owner may furnish other
security satisfactory to Declarants to ensure completion of the

sign exceed ten (10) feet measured from curb elevation.

                  5. A sign cannot be located in street right-of-ways, but can
be located in any front or side yard area that does not obstruct the sight lines
at a street or driveway intersection, as determined by the Village. Sign
location should also not block or detract from adjacent property.

                  6. The base of the sign must be landscaped.

                  7. Only a corporate name, type of business, street address,

                     Package which would be compatible and harmonious with the
                     architectural scheme of the Property and the Building Site,
                     and also be in general compliance with the intent of these
                     signage guidelines, but would also allow some minor

                     allow for individualized colors and corporate logos and
                     graphics.


                  13. A simple, single line sign with uniform lettering not to
exceed 5" in height may be affixed or placed on the exterior of a loading

employees in connection with construction, and the Building Site, free from any
dirt, mud, garbage, trash or other debris which might be occasioned by such
construction.

         B. DAMAGE TO IMPROVEMENTS. If any Improvement is damaged or destroyed,
the Owner shall promptly (but in no event more than Twelve (12) months after the
date of the casualty) restore such Improvement to the condition existing prior
to such damage or destruction or, in the alternative, raze and remove such
Improvement and landscape the Building Site pursuant to a landscaping plan
approved as provided in Section V hereof.

         C. LANDSCAPE VACANT BUILDING SITE. If the Owner does not commence
construction of Improvements upon the Building Site within six (6) months of the
date of recording a Deed to an Owner, the Owner shall landscape the Building
Site with no less than an appropriate ground cover, such as field grass or sod,
and thereafter maintain such ground cover in a clean, neat and safe condition,
keeping it mowed at a height not to exceed four (4) inches until the
commencement of construction of Improvements. The aforesaid six (6) month period
may be extended with the written approval of Declarants.

         D. RIGHT TO PERFORM OWNER'S MAINTENANCE. If an Owner shall fail to
perform Owner's Maintenance as aforesaid or the landscaping work in accordance
with the provisions hereof, Declarants may give written notice to the Owner
specifying the manner in which the Owner has failed to so perform. If such
failure has not been corrected within ten (10) days after such notice, or if
such work, if it cannot be completed within such ten (10) day period, has not
been commenced within such period and thereafter diligently completed,
Declarants may enter upon the Building Site and perform such work. Declarants by
reason of their performing such work shall not be liable or responsible to the
Owner for any losses or damage thereby sustained by the Owner or anyone claiming
by or under the Owner except for gross negligence or wanton or willful acts. The
Owner shall be liable for the cost of such work and shall promptly reimburse
Declarants for such cost, together with interest calculated from the date of
expenditure until repayment, at the Default Interest Rate. If the Owner shall
fail to reimburse Declarants within thirty (30) days after receipt of a
statement for such work from Declarants then said indebtedness shall be a debt
of the Owner, and shall constitute a lien

                                      13
<PAGE>


against that Building Site on which said work was performed. Such lien shall
have the same attributes as the lien for changes set forth in Section VIII.A.7.
hereof, and Declarants shall have identical powers and rights in all respects,
including but not limited to, the right of foreclosure.

         E. MAINTENANCE EASEMENT. Declarants hereby reserves, for themselves and
for their designees or employees, and for the Association, the free and
unrestricted right, license and privilege to have free and unrestricted access
upon and across Lincoln Commerce Center and each Building Site, and, upon
reasonable notice, any Improvements thereon, for the purpose of performing any
work the Declarants shall have the right to perform pursuant to the provisions
of this Declaration, including but not limited to the performance of Owner's
Maintenance which an Owner fails to perform. Each Owner, mortgagee, tenant or
occupant of any Building Site, by accepting title thereto or an estate therein,
shall be deemed to have consented to the foregoing reservations and to have
granted the foregoing rights. The Declarants and the Association shall use all
reasonable efforts to avoid interfering with the normal business operations of
anyone occupying such Building Sites.


VII. STORM WATER FACILITIES.

         A. EASEMENTS. Easements for the retention and/or detention of water for
the benefit of the Lincoln Commerce Center and the individual Building Sites are
hereby declared upon those portions of the Property which are designated herein
for such purpose or on the Plat of Subdivision as Private Water Detention
Easements and/or Wetlands and Stormwater Management Facilities. It is understood
that any such retention and/or detention areas may, in the future, be reshaped,
altered, or relocated within the aforementioned easements to meet required
governmental standards or engineering requirements, but no such reshaping,
alteration, or relocation shall be made without the prior written approval of
the Village.

         B. MAINTENANCE. It is recognized and understood that the Private Water
Detention Easements and the Wetlands and Stormwater Management Facilities (the
Storm Water Facilities) serve both important functional and aesthetic purposes
and that their repair and maintenance are of vital concern to all parties having
an interest in Lincoln Commerce Center. In order to ensure that these areas are
in full and good working order, are sightly and well kept, and comply with
applicable governmental regulations, they are to be considered Common Area and
the responsibility for their maintenance and repair, including the cost thereof,
shall be that of the Declarants. The Storm Water Facilities on any Building Site
shall include any area designated Private Water Detention Easement on the Plat
of Subdivision. Where necessary or advisable, said delineation may be adjusted
in order to accommodate specific topographical conditions and/or the location of
Improvements and, where feasible and practical, a physical demarcation should be
utilized in order to facilitate recognition of the respective maintenance areas.
Notwithstanding anything herein to the contrary: (i) the Owners of each Building
Site shall be responsible for the maintenance, including the cost thereof, of
plantings located adjacent to any pond on the Owner's Building Site; and (ii)
areas

                                      14
<PAGE>


designated Wetlands and Stormwater Management Facilities and Private Water
Drainage Easements on the Lincoln Commerce Center Plat of Subdivision and
located on a Building Site shall be maintained by the Owner thereof (said
maintenance shall include, but not be limited to, keeping Storm Water Facilities
clear of debris and other accumulations, insuring that the flow of storm water
is not blocked or hindered, and maintaining the Storm Water Facilities in
accordance with the landscaped plan for the Building Site).

         C. IMPAIRMENT. It is understood that no Owner, by either act or
omission, shall do or refrain from doing any act the effect of which will impair
the function and/or aesthetics of the Storm Water Facilities or any
appurtenances utilized in connection therewith. Where as a result of the act or
omission of an Owner, its agents, invitees, contractors, subcontractors,
employees, etc., an extraordinary expense is incurred by the Association with
regard to the repair or maintenance of the Storm Water Facilities, such expense
shall be due and payable by the party so charged upon demand therefor, the
unpaid portion of which shall accrue interest at the Default Interest Rate, and
shall be a lien in the same manner as provided hereinafter in Section VIII.A.7.

                  5. MEMBERSHIP. Upon formation of the Association, each Owner
of a Building Site shall be a member of the Association and each purchaser of a
Building Site by acceptance of conveyance thereof, covenants and agrees to
become a member of the Association. Membership in the Association shall
automatically terminate upon the sale, transfer, or other disposition of a
member's title ownership in a Building Site, at which time the new Owner of such
title interest shall automatically become a member of the Association. No member
shall have any right or power to disclaim, terminate, or withdraw from his
membership in the Association or from any of its obligations as a member by
non-use of the Common Areas or otherwise.

                  6. VOTING RIGHTS.  The Association shall have two (2) classes
of voting membership:

                  a)       CLASS A.  Class A members shall be all those who own
                           Building sites within Lincoln Commerce Center except
                           the Declarants.  Each Class A member shall be
                           entitled to one (1) vote for each forty thousand
                           (40,000) square feet of the Property (land area) that
                           said member owns within Lincoln Commerce Center.
                           Fractional votes shall be determined by rounding the
                           remainders to the nearest ten thousand (10,000)
                           square feet and dividing the rounded number by forty
                           thousand (40,000) (thus, votes shall be cast only in
                           fractions divisible by .25). Where more than one
                           party

                                       16
<PAGE>

                           holds the particular interest or interests, the vote
                           for such square footage shall be exercised as said
                           Owners determine among themselves, but in no event
                           shall more than one (1) vote be cast with respect to
                           any forty thousand (40,000) square feet or part
                           thereof as aforesaid.

                  b)       CLASS B.  The Class B voting members shall be the
                            Declarants.  The Class B voting members shall be
                            entitled to three (3) votes for each forty thousand
                            (40,000) square feet of Property (Land Area) that
                            the Declarants own within Lincoln Commerce Center.
                            Fractional votes for the Class B voting member shall
                            be computed in the same manner as provided
                            hereinabove for the Class A members.

Notwithstanding anything to the contrary in this Declaration, amendments to this
Section VIII A. 6. Shall only be effective upon the unanimous written consent of
all Class A voting members and all Class B voting members.

                  7. LEVYING OF ASSESSMENTS.

                  a) AUTHORITY. The Declarants and/or the Association shall have
                  the power to levy general and special assessments and charges
                  upon and against the Owners of the Building Sites, the
                  Property or any portion thereof in Lincoln Commerce Center for
                  the purpose of carrying out the obligations, duties and powers
                  herein set forth, including any legal and other costs incurred
                  in enforcing this Declaration in accordance with the terms
                  hereof. Specifically, such funds received from such
                  assessments or charges shall be expended by the Declarants or
                  the Association for (i) the providing for, the maintaining and
                  operating the Common Areas, including, without limitation:
                  entrances, street rights-of-way, pathways, recreational
                  facilities, directional and informational signs, signs
                  identifying Lincoln Commerce Center, public area lighting,
                  park area, wet lands, storm sewers, detention and retention
                  areas, street medians, drainage, and any other improvements
                  relating to the enhancement of the overall quality of Lincoln
                  Commerce Center; (ii) the payment of real estate taxes on the
                  Common Areas; (iii) providing for the administration and
                  enforcement of this Declaration, including reasonable
                  administrative staff requirements and expenses; and (iv) to
                  fulfill any of the obligations of the Association and
                  Declarants hereunder. Each Owner of a Building Site by the
                  acceptance of the Deed for said Building Site, whether or not
                  such obligation be so expressed in any such deed or other
                  conveyance, for each Building Site owned by each Owner,
                  together with Declarants, hereby covenants and agrees and
                  shall be deemed to have covenanted and agreed to pay to the
                  Association and/or the Declarants, as the case may be, all
                  assessments and charges as are levied pursuant to the
                  provisions of this Declaration. All assessments and charges,
                  together with interest thereon at the Default Interest Rate if
                  not paid when due, and the costs of collection, if any,
                  including attorneys' fees, as herein provided, shall be
                  charged as a continuing lien upon the Building Site against
                  which each such charge is made. Each such assessment or charge
                  as aforesaid, together with interest and

                                       17
<PAGE>


                  costs thereon, shall, in addition, be the personal obligation
                  of the Owner of such Building Site at the time the assessment
                  or charge was levied by the Declarants or the Association.
                  Declarants, to the extent that they own any part of the
                  Property, shall be deemed subject to the provisions of this
                  Section.

                  b) PROCEDURES. Commencing with the first fiscal year and for
                  each year thereafter, the Association or the Declarants shall
                  estimate in writing its costs of operation for the coming year
                  and same shall be assessed and paid no more frequently than
                  quarterly in advance by each Owner or as Declarants or the
                  Association shall otherwise direct. Such assessment shall take
                  into consideration the cost of or reserves for any
                  contemplated repair, replacement, or renewal of a specified
                  improvement upon the Common Areas or the personal property and
                  facilities maintained by the Declarants or the Associations.
                  If the assessment proves inadequate for any reason (including
                  non-payment of any Owner's assessment) or proves to exceed
                  funds reasonably needed, then the Declarants or the
                  Association may increase or decrease the assessments payable
                  hereunder by giving written notice thereof (together with a
                  revised estimate) to each Owner not less than ten (10) days
                  prior to the effective due date for the payment of the revised
                  assessment. At least once each year, the Declarants or the
                  Association shall deliver to each Owner a statement of actual
                  costs for the prior year along with a reconciliation of
                  estimated assessments with actual costs and reserves. The
                  Association shall have the power to levy additional
                  assessments as provided in the By-Laws of the Association.
                  Each Owner shall be assessed for a prorata share of all
                  assessments, such share to be determined by a fraction, the
                  numerator of which is the number of square fee of the Property
                  owned by the Owner, and the denominator of which is the number
                  of total square feet of land contained in the entire Property
                  less any portion of the Property which is dedicated to a
                  governmental body (included but not limited to the Village),
                  public or private streets owned by the Declarants or the
                  Association and/or any Common Areas. Any Owner shall have the
                  right to examine the Declarants' or the Association's records
                  relative to any assessment, provided that reasonable notice is
                  first given and provided that said Owner bears all costs of
                  said examination. All assessments shall be prorated as of the
                  date title transfers to a new Owner.

                  c) NOTICE OF ASSESSMENT. Notice of each assessment shall be
                  given by sending a written notice by postage prepaid United
                  States mail addressed to the last known or usual post office
                  address of the Owner of any Building Site or by posting a
                  brief notice of the assessment upon the Building Site itself.

                  d) NONPAYMENT OF ASSESSMENT. Any assessments or charges which
                  are not paid within thirty (30) days after due date shall be
                  delinquent. All delinquent assessments shall bear interest at
                  the Default Interest Rate.

                  e) LIEN.  To evidence a lien on a Building Site which is

                                      18
<PAGE>

                  delinquent in the payment of an assessment or a charge,
                  Declarants shall prepare a written notice of assessment lien
                  setting forth the amount of the unpaid indebtedness, the name
                  of the Owner of such Building Site subject to such lien and a
                  legal description of such Building Site ("Notice"). The Notice
                  shall be signed by one of the officers of the Declarants or
                  the Association and shall be recorded in the Office of the
                  Recorder of Deeds of Lake County, Illinois. Such lien for
                  payment of charges shall attach to the affect Building Site
                  after recording the Notice and may be enforced by all
                  available legal methods of collection including, but not
                  limited to, the foreclosure of such lien by Declarants in like
                  manner as a mortgage on real property, or Declarants or the
                  Association may institute suit against the Owner obligated to
                  pay the assessment and/or for the foreclosure of the aforesaid
                  lien judicially. In any foreclosure proceeding, whether
                  judicial or not judicial, the Owner shall be required to pay
                  the costs, expenses and reasonable attorneys' fees incurred in
                  connection therewith. Declarants or the Association shall have
                  the power to bid on such Building Site at foreclosure or other
                  legal sale and to acquire, hold, lease, mortgage, convey or
                  otherwise deal with the same. Upon the written request of any
                  mortgagee holding a prior lien on any part of the Building
                  Site, Declarants or the Association shall report to said
                  mortgagee any unpaid charges or assessments remaining unpaid
                  for longer than sixty (60) days after the same are due.

                  f) SUBORDINATION OF LIEN TO PRIOR ENCUMBRANCES. The recorded
                  Notice evidencing the lien for any charge or assessment
                  provided in this Declaration shall be superior to all other
                  liens, encumbrances and charges against the Building Site,
                  except only as against previously recorded, or for liens
                  securing payment of taxes, special assessments and special
                  taxes heretofore or hereafter levied by any political
                  subdivision or municipal corporation or any state or federal
                  taxes which by law are a lien against the interest of any such
                  Owner prior to pre-existing recorded encumbrances; and
                  provided further, that said recorded Notice evidencing such
                  assessment lien shall be subordinate to the lien of a prior
                  recorded bona fide security device, including a mortgage,
                  trust deed or sale and leaseback encumbering said Building
                  Site, except for such amounts which become due and payable
                  from and after the date on which the holder of such security
                  device either (i) takes possession of said Building Site, or
                  (ii) accepts a conveyance of any interest therein other than
                  as security, or (iii) files suit to foreclose its security
                  device. Declarants or the Association shall have the power to
                  subordinate the aforesaid lien to any other lien. Such power
                  shall be entirely discretionary with Declarants or the
                  Association. A transfer of title shall not relieve the
                  Building Site from the lien for any charges thereafter
                  becoming due nor from the lien of any subsequent charges.

                  h) EXEMPT PROPERTY. All parts of the Lincoln Commerce Center
                  dedicated to and accepted by the Village or any other public
                  authority, or owned by the Association as Common Areas, shall
                  be exempt from assessments, charges, and liens created under
                  this Declaration.

                  i) BY-LAWS. Upon incorporation of the Association, the
                  Directors shall establish appropriate By-Laws for the
                  Association through which the Association can carry out the
                  purposes of this Declaration.

         B. ENFORCEMENT. This Declaration shall operate as a covenant running
with the land, and all provisions hereof shall be enforceable by Declarants, the
Association, Village, and every Owner by proper proceedings, either in equity or
at law. Further, Declarants, and the Association shall have the right to sue for
and obtain an injunction, prohibitive or mandatory, to prevent the breach of or
to enforce the observance of the covenants, conditions, restrictions,
reservations and easements herein set forth, but the failure of the Declarants
or the Association to enforce any of the covenants, conditions, restrictions,
reservations or easements herein set forth, at the time of any violation, shall
not be deemed to be a waiver of the rights of the Declarants or the Association
to do so as to any subsequent violation. This Declaration may also be enforced
by (i) suit to recover damages, (ii) suit to enforce a lien against the Owner's
Building Site, or (iii) any other available remedy at law or equity. Further,
Declarants and the Association are each empowered to take all immediate action
it deems necessary, at the cost and expense of any Building Site Owner, to
correct any violation of this Declaration relating to such Building Site,
including without limitation the power to exercise the right, license, and
permission to enter upon any Building Site with men, equipment, materials and
other necessary articles, all without being guilty of trespass and without being
subject to any liability or damages, to complete any work necessary to correct
any violation of this Declaration. Reasonable care will be used in the
performance of such work. In the event that Declarants or the Association deem
it necessary to secure the service of an attorney to enforce any provision of
this Declaration, the fee of such attorney and all other costs connected with
the contemplated or actual legal proceedings shall be paid by the Owner of the
Building Site which is the subject of the proceedings. Written notice of such
costs shall be given to the Building Site Owner and such costs shall be
reimbursed by the Building Site Owner within ten (10) days after the date of
such notice. If such costs remain unpaid, they shall be considered delinquent
and shall constitute a lien upon the Building Site.


IX. COMMON AREAS AND DRAINAGE FACILITIES.

         Upon the establishment of the Association, the Declarants shall convey
to the Association all of its right, title and interest to the Common Areas and
assign to the Association any or all of its obligations for the performance of
maintenance of the Common Areas and drainage facilities.


X. RIGHT TO RE-SUBDIVIDE.

         Once a Building Site has been purchased from Declarants, its successors
or assigns, such Building Site shall be considered as a single unit and further
subdivision of a portion of the Building Site is prohibited unless written
approval is given by Declarants or the

                                      20
<PAGE>

Association, which approval shall not be unreasonably withheld.


XI. ADDITIONAL LAND.

         Declarants, from time to time and at any time before and after it has
conveyed all of the Lincoln Commerce Center, shall have the right to render
other land that is adjoining to the Lincoln Commerce Center or to any other
property then subject and subservient to this Declaration in all respects by
executing and recording a supplement to this Declaration containing: A legal
description of the land to be added; a statement that Declarants is the record
owner in fee simple of such land, or in lieu thereof; a statement that all other
persons, firms or corporations having an interest in such land have joined in
such supplement; a statement of the additional restrictions or burdens to which
such land shall be subjected, if any; and a statement of the restrictions,
burdens or provisions of this Declaration which shall be applicable to such land
in modified form, if any. Following the execution, delivery and recording of
such supplement, but subject to its terms, such land and the then and future
owners, tenants, mortgagees and other occupants of all or any part thereof shall
in all respects be fully subject to this Declaration and all rights, privileges,
obligations, duties, liabilities, responsibilities, burdens and restrictions
contained herein, including but not limited to, the obligation for payment of
assessments, as though such land had originally been included in and subject to
this Declaration.


XII. DURATION OF RESTRICTIONS.

         Each of the conditions, covenants, restrictions, reservations and
easements herein contained shall continue and be binding upon Declarants and
upon its successors and assigns and upon each of them, and all parties and
persons claiming under Declarations for a term of fifty (50) years from the date
this Declaration is recorded, after which time it shall automatically extend for
successive periods of five (5) years unless an instrument has been recorded
signed by all the then Owners of all of the Building Sites, agreeing to
terminate this Declaration.


XIII. APPOINTMENT OF SUCCESSOR TO DECLARANTS.

         If Declarants transfers or leases all or substantially all of their
then interest in and to the Property in a single transaction (which transfer
shall be deemed to include a transfer resulting from foreclosure or deed in lieu
of foreclosure), all of Declarants' rights under this Declaration may be
assigned to and assumed by such transferee or lessee. The Declarants may, at any
time, transfer all of their rights, duties and obligations under this
Declaration to the Association. Such transfer shall be effective and binding
upon the Association as of the day it is notified of such transfer. The
foregoing transfers and assignments shall be evidenced by signed and
acknowledged written declarations recorded in the Office of the Recorder of
Deeds for Lake County, Illinois. In the event Declarants or their duly
designated successors shall no longer possess a fee simple interest in the
Property, the rights and obligations

                                       21
<PAGE>

of Declarants shall devolve to the Association.


XIV. RESERVATION OF EASEMENTS FOR UTILITIES.

         Non-exclusive Easements for the benefit of Declarants are hereby
declared in the designated set back areas between the building lines (designated
on the Flat of Subdivision or in Village ordinances) and the boundaries of
individual Building Sites as may be necessary or convenient for the purpose of
erecting, constructing, maintaining, and operating utility services over,
across, under and through the Property (including but not limited to public
service wiring, conduits or lighting, power and telephone lines, gas lines,
sanitary sewer, storm sewer and water). Said easement, at Declarants' election,
may be assigned to the Village, the Association and/or appropriate public
agencies and utilities. No Buildings may be located upon said easement but,
subject to the limitations of Village ordinances and this Declaration,
landscaping, parking and access drives may be located thereon.


XV. CERTIFICATE OF COMPLIANCE.

         Upon payment of a reasonable fee and upon written request of any Owner,
mortgagee, tenant or occupant, either current or prospective, of a Building
Site, Declarants shall issue an acknowledged certificate in recordable form
setting forth the amount of any unpaid charges, if any, and setting forth
generally whether or not said Owner is, to the best knowledge of Declarants, in
violation of any of the terms and conditions of this Declaration. Such statement
shall be furnished by Declarants within a reasonable time, but not to exceed
twenty (20) days from the receipt of a written request for such written
statement. If Declarants fails to furnish such statement within said twenty (20)
days, it shall be conclusively presumed that there are no unpaid charges
relating to the Building Site as to which the request was made, and that said
Building Site is in conformance with all of the terms and conditions of this
Declaration.


XVI. RULE AGAINST PERPETUITIES.

         If and to the extent that any of the covenants herein would otherwise
be unlawful or void for violation of (a) the rule against perpetuities, (b) the
rule restricting restraints on alienation, or (c) any other applicable statute
or common law rule analogous thereto or otherwise imposing limitations upon the
time for which such covenants may be valid, then the provision concerned shall
continue and endure only until the expiration of a period of twenty-one (21)
years after the death of the last to survive of the class of persons consisting
of all of the lawful descendants of President George Bush, living at the date of
this Declaration.


XVII. DECLARANTS' AGENT.

         The Declarants may appoint an agent to act in their stead for any or

                                       22
<PAGE>


all purposes provided for herein, including but not limited to the granting of
all approvals and consents of the Declarants as required herein, the assessing,
billing and collection of all charges and assessments including the imposition
of liens, and the acceptance of service and notices provided for herein. The
Declarants' appointment of said agent or any change, modification, limitation or
termination thereof shall be made by a written notice to all the Owners, sent by
U.S. Mails, by certified mail, return receipt requested.

by judgment or court order shall in no way affect any of the other portions, all
of which shall remain in full force and effect.

         B. INTERPRETATION. This Declaration shall be interpreted for the mutual
benefit and protection of the Owners and tenants of the Lincoln Commerce Center
and in furtherance of the basic goals of this Declaration. Any discrepancy,
conflict or ambiguity which may be found herein shall be resolved and determined

Sites. Neither Declarants or the Association nor their agents or employees nor
any disclosed or undisclosed principals of Declarants shall have any personal
liability with respect to any of the provisions of this Declaration or the
Property, or shall they be liable in damages or otherwise to anyone submitting
Plans and Specifications for approval or making any other request of Declarants,
or to any Owner, tenant or subtenant of Property in the Lincoln Commerce Center,
by reason of any mistake in judgment, or any negligence or nonfeasance arising
out of or in connection with (i) the approval or disapproval, or failure to
approve or disapprove, any Plans and Specifications or other request; (ii) the
enforcement or failure to enforce the terms of this Declaration; and (iii) the
administration of this Declaration; and anyone who submits Plans and
Specifications or any request to Declarants for approval, by the submission of
such Plans and Specifications or request, and the Owner, tenant, mortgagee or
subtenant, by acquiring title to or an interest in any Building Site or interest
whatsoever in the Property or any part thereof, agrees, to the extent permitted
by law, not to bring any action

                                      23
<PAGE>

or suit to recover from any such damages against Declarants. Further, if
Declarants is in breach or default with respect to Declarants' obligations under
this Declaration or otherwise, any interested party shall look solely to the
equity of Declarants in the Property for the satisfaction of any obligation of
liability.

         F. AMENDMENTS. The Declarants and/or the Association shall have and
they are hereby granted the power to amend, modify, or otherwise alter this
Declaration and each and all of the terms and provisions hereof and each and all
of the rules, covenants, easements, agreements, and restrictions herein
contained, at any time and from time to time; provided however if the
Association has been established, then such action must be recommended by the
Board of Directors and approved by the affirmative vote of 75% of the votes of
the Owners (as provided by Section VIII A. 6.), subject to the limitation that
such action shall not cause the Common Areas, or any part thereof, to be in
noncompliance with any zoning ordinance or other applicable law or governmental
regulation. The Declarants and/or the Association hereby reserves the right to
amend this Declaration at any time for the purpose of correcting clerical errors
or clarification of the terms of the Declaration without the consent or approval
of the Board of Directors, the Owners or any other party, provided said
amendments do not constitute a material and substantial change to the
Declaration. Anything herein to the contrary notwithstanding, no changes or
amendments to this Declaration which would affect the rights reserved herein to
the Village shall be effective without the prior written approval of the
Corporate authorities.

         G. RECAPTURE AND VILLAGE CHARGES. Nothing contained in this Declaration
shall in any manner limit the right of the Declarants to enter into and enforce
Recapture Agreements with the Village or any other governmental authorities
having jurisdiction over the subject matter of such Agreements.

         H. NOTICES. Any notice required or desired to be given under this
Declaration shall be in writing and shall be deemed to have been properly served
when delivered in person and receipted for or after deposit in the United States
Mail, certified mail, return receipt requested, postage prepaid, addressed to an
Owner, at its last known address as shown on the records of the Declarants or
the Association, at the address to which assessments are mailed. All notices to
the Declarants shall be sent in the manner as aforesaid to:

         TMA Group Development Corporation
         145 E. Algonquin Road

or at such other place or party as the Declarants may indicate by an amendment
to this Declaration properly recorded with the Recorder of Deed of Lake County.

         I. DELAY IN PERFORMANCE - FORCE MAJEURE. If the performance of any act
or obligation under this Declaration is prevented or delayed by an act of God,
fire, earthquake, flood, explosion, action of the elements, war, invasion,
insurrection, mob violence, sabotage, malicious mischief, inability to procure
or general shortage of labor, equipment or

                                       24
<PAGE>


facilities, materials or supplies in the open market, failure of transportation,
strike, lockout, action or labor union, condemnation, threatened condemnation,
requisitions, laws, orders of government or civil or military or naval
authorities or any other cause whether similar or dissimilar to the foregoing
not within the reasonable control of the person required to perform such act or
obligation, then such person shall be excused from the performance of such act
or obligation for so long as such person is so prevented or delayed by reason
thereof. This force majeure provision shall apply to Declarants, the Association
and each Owner's obligations hereunder except those that require the payment of
money.

         J. BINDING EFFECT OF DECLARATION. All the rights, covenants,
agreements, reservations, restrictions and conditions herein contained shall run
with the land and shall inure to the benefit of and be binding upon Declarants
and each subsequent holder of any interest in any portion of the Property and
their grantees, heirs, successors, personal representatives and assigns with the
same full force and effect for all purposes as though set forth at length in
each and every conveyance of the Property or any part thereof. Reference in the
respective deeds of conveyance, or in any mortgage or trust deed or other
evidence of obligation, to the easements and covenants herein described shall be
sufficient to create and reserve such easements and covenants to the respective
grantees, mortgagees or trustees of such parcels as fully and completely as
though said easements and covenants were fully recited and set forth in their
entirety in such documents.

         K. CONFLICTS. If Declarants obtain a zoning variance with regard to any
portion of the Property in which Declarants hold record title and such zoning
variance provides for less restrictive standards than the standards set forth in
this Declaration, then the provisions of such zoning variance shall apply to
that portion of the Property so affected and the provisions of this Declaration
as to such standards shall be unenforceable by any other Owner with regard to
such portion of the Property.

         L. RIGHTS OF THE VILLAGE. In addition to any rights, powers or
easements granted to the Village elsewhere in this Declaration, the Village
shall have the rights, powers and easements set forth in this Section.

                  1. ENTRY UNTO THE PROPERTY. The Village has the right to enter
upon, on, and over areas utilized for Storm Water Facilities, Wetlands and
Stormwater Management Facilities, Private Water Detention Easements, Common
Areas, driveways, entrances and other property used for ingress and egress to
the Property and/or to a Building Site to determine whether any of the said
areas are in violation or not in conformity with applicable restrictions,
regulations and covenants of this Declaration.

                  2. NOTICE BY VILLAGE. If the Village reasonably determine that
any of the above areas are in violation or not in conformity with this
Declaration, the Village may give the Association, the Declarants and/or an
Owner written notice of such determination. The notice which the Village shall
give shall be in writing and shall permit the Association, the Declarants, or
the Owner, as the case may be, not less than thirty (30) days to cure the
violation. Provided, however that if an

                                      25
<PAGE>


emergency exists requiring immediate intervention by the Village, the Village
shall have the right to make emergency repairs or take emergency action without
providing written notice, but may, if time permits, give oral notice.

                  3. FAILURE TO CORRECT. If the Association, the Declarant, or
an Owner fails to perform any required act or to desist from taking a prohibited
act within the time permitted under this Declaration, or in the absence of such
specific time, within thirty (30) days after receiving above described notice of
the determination, the Village shall have the right to perform or cause to be
performed such maintenance or other action or operations necessary to correct
the violation, to abate the prohibited act, to fulfill the conditions of this
Declaration or to bring the Property into compliance with such restrictions,
regulations and covenants as are being ignored or violated.

                  4. RIGHT OF REIMBURSEMENT. If the Village performs such
services or has such services performed, it shall be entitled to complete
reimbursement by the Association, the Declarants, or an Owner, as the case may
be, and, if not paid within thirty (30) days after an invoice therefor is given,
may place a lien upon the Property or the Building Site affected, in an amount
equal to the sum owed. Further, the Village shall have the right to enforce
compliance with the provisions of this Section by injunction or other legal
proceedings and to recover damages and costs of reasonable attorneys' fees which
may arise thereby.

                  5. GENERAL. The rights of the Village to enforce the
provisions of this Declaration, as set forth in this Section, may not be amended
by the Declarants, Association or the Owners without the written permission of
the Village. The Village shall not be obligated to enforce the provisions of
this Declaration, but may do so at its sole discretion.
