2.      LEASED PREMISES, TERM AND FAILURE TO GIVE POSSESSION

2.01    Lease of Premises

        Landlord hereby leases to Tenant and Tenant hereby leases from Landlord
the premises (the "Leased Premises") shown on Exhibit A which are or will be
contained in the office building (the "Building") located at 111 West Jackson
Boulevard, Chicago, Cook County, Illinois, for the term and upon the conditions
provided in this Lease.

2.02    Term

        The term of this Lease ("Term") shall commence on the date
("Commencement Date") specified in 1.01.E.3. The term shall expire on the date
("Expiration Date") specified in 1.01.E.5, unless sooner terminated as
otherwise provided elsewhere in this Lease.

2.03    Failure to Give Possession

        If Landlord shall be unable to give possession of the Leased Premises on
the date specified in Section 1.01.E.2 ("Possession Date") by reason of any of
the following: (i) Landlord has not completed its preparation of the Leased
Premises, (ii) Landlord is unable to give possession of the Leased Premises by
reason of the holding over or retention of possession of any tenant, tenants or
occupants, or (iii) for any other reason, Landlord shall not be subject to any
liability for the failure to give possession on said date. Under such
circumstances the Monthly Base Rent reserved and covenanted to be paid herein
shall not commence until three days after the Leased Premises are available for
occupancy by Tenant (which date shall then be the Lease Commencement Date and
Rent Commencement Date, amending the dates specified in subsections 1.01.E.3
through 7 to provide full term; in such instance, the Parties shall execute an
addendum ("Commencement Date Addendum," setting forth said Lease Commencement
Date and Rent Commencement Date), and no such failure to give possession on the
specified Possession Date shall affect the validity of this Lease or the
obligations of Tenant hereunder. In the event that the afore-described delays
occurs, Landlord and Tenant shall memorialize the amended operative dates in an
addendum hereto, nor shall the same be construed to extend the term of this
Lease. If the Leased Premises are ready for occupancy prior to the Possession
Date and Tenant occupies the Leased Premises prior to said date, Tenant shall
pay Monthly Base Rent for the period of occupancy prior to the date specified in
1.01.E.4 ("Rent Commencement Date") on a proportionate per diem basis. The
Leased Premises shall not be deemed to be unready for Tenant's occupancy or
incomplete if only minor insubstantial details of construction, decoration or
mechanical adjustments remain to be done in the Leased Premises or any part
thereof, or if the delay in the availability of the Leased Premises for
occupancy shall be due to special work, changes, alterations or additions
required or made by Tenant in the layout or finish of the Leased Premises or any
part thereof or shall be caused in whole or in part by Tenant through the delay
of Tenant in submitting plans, supplying information, approving plans,
specifications or estimates, giving authorizations or otherwise or shall be
caused in whole or in part by delay and/or default on the part of Tenant and/or
its subtenant or subtenants. In the event of any dispute as to whether the
Leased Premises are ready for Tenant's occupancy, the decision of Landlord's
architect shall be final and binding on the Parties.

        (A)    Payment Schedule
<PAGE>
                                                                          PAGE 5

              (1)    Monthly Installment of Annual Base Rent
                     Tenant shall pay to Landlord as Annual Base Rent for the
              Leased Premises from and after the date specified in Section
              1.01.E.4 (the "Rent Commencement Date") the sum set forth in
              Section 1.01.F, payable in Monthly Installments of Base Rent as
              set forth herein, and Additional Rent, as set forth herein, on the
              first day of every calendar month, in advance. The provision by
              Landlord of monthly statements is a courtesy and shall not create
              any liability upon Landlord therefor, or condition Tenant's
              obligation to remit Monthly Rent upon receipt thereof.

              (2)    Additional  Rent (Tenant's Proportionate Share of Taxes,
              Insurance, and Operating Expenses)
                     Tenant shall further pay Additional Rent (which is
              comprised of Taxes, Insurance, and Operating Expenses, defined
              under subsection 3.02(A)), on an annual basis, unless Landlord
              provides written notice to Tenant that, pursuant to subsection
              3.02(B), monthly installments therefor shall be due. In the
              absence of such notice, annual payments shall be due within thirty
              (30) days of Tenant's receipt of written invoice therefor.

              (3)    Additional Rent (Remaining Charges)
                     Tenant shall pay all other Additional Rent (which is
              comprised of all other charges, costs and sums required under the
              Lease (e.g. Additional and After-Hours Services) within ten (10)
              days of receipt of written invoice therefor.

        In the event that the Rent Commencement Date shall occur on a day other
        than the first day of the month, the payment of all Rent due for such
        partial month shall be adjusted for the proportionate fraction of the
        whole month and shall be due and payable on the Commencement Date. All
        subsequent Rent payments shall be made and become due and payable, in
        advance, on the first day of each calendar month during the term hereof.
        Rent shall in same manner be prorated in the event that the date of
        termination of the Lease, after either the original term or option
        period, shall fall on other than the last day of the month.

        (B)   In the event of Tenant's failure to remit monies specified in this
        section on the date due, certain late payment fees and interest charges,
        as specified in subsection 25.01, may apply, in addition to all of
        Landlord's other rights and remedies provided under this Lease and by
        law.

3.02    Additional Rent

        All other charges, costs and sums required to be paid by Tenant to
Landlord under this Lease shall be deemed Additional Rent, and together with
Monthly Installments of Annual Base Rent, shall hereinafter be collectively
called "Rent." Tenant's covenant to pay Rent shall be independent of every
other covenant in this Lease.

        (A)   Tenant's Obligation.
              In addition to Annual Base Rent, Tenant shall reimburse to
        Landlord as Additional Rent, Tenant's Proportionate Share, as set forth
        in Section 1.01.G.2 hereof, of Taxes, Operating Expenses, and Insurance,
        each as hereinafter defined, in excess of Landlord's

<PAGE>

                                                                          PAGE 6

actual expenses for Taxes, Operating Expenses and Insurance paid in the Base
Year.

     (1)  TAXES.
          (a)  For purposes hereof, "Taxes' shall mean all real estate taxes,
          rates, levies, charges and assessments, general and special, ordinary
          and extraordinary, of every kind and nature whatsoever, whether now
          known to law or hereafter created, which may be taxed, charged,
          assessed or levied or imposed during the term of this Lease, or any
          renewal or extensions hereof, upon the Building. Any reasonable cost
          incurred by Landlord in an effort to minimize, reduce, protest,
          negotiate or otherwise adjust any real estate tax bill, tax assessment
          or assessed valuation, including the cost of appraisals, witness fees
          and attorneys' fees related thereto, shall be included in the
          definition of Taxes. With regard to betterments and special
          assessments attributable to and levied or assessed against the
          Building Landlord and Tenant agree that they shall be paid for over
          the maximum period allowed by laws and "Taxes" shall include only of
          those installments which fall due during the term of this Lease. In
          the event that Landlord secures a refund or reduction in Taxes for a
          particular year for which Tenant has paid its share of Taxes
          hereunder, Tenant shall be given a credit against Rent for its
          proportionate share of such refund or reduction, less the reasonable
          costs identified supra. In the event that the term hereunder shall
          have ended, Landlord will remit such monies to Tenant in the manner
          provided in 3.01(B).

          (b)  Anything contained in this Lease to the contrary
          notwithstanding, Tenant shall not be obligated to pay any capital,
          stock, franchise, income, estate, gift, inheritance, excise or other
          similar taxes or impositions which may be levied against Landlord or
          its successors in title. If however, at any time during the term
          hereof, the methods of taxation prevailing at the Commencement Date
          shall be altered so that, by virtue of new legislation which either
          specifically provides or demonstrates by its legislative history that
          the taxes or fees therein levied, assessed or imposed are in lieu of
          or a substitute for the whole or any part of the Taxes then levied,
          assessed or imposed on the Building, real estate and the improvements
          thereon, and through such legislation, there shall be levied, assessed
          and imposed(a) a tax, wholly or partially as a capital levy or
          otherwise, on the rents received under this Lease or (b) a tax or
          license fee measured by the rent payable to Landlord hereunder, then
          to the extent that Landlord shall be required to pay such tax which is
          attributable to the Leased Premises, Tenant shall pay and discharge
          same, (or pay same to Landlord, if collected from Landlord) on the
          later of thirty (30) days after being notified of such tax or prior to
          delinquency, which ever is later.

     (2)  INSURANCE.
          For purposes hereof, "Insurance" shall mean such insurance that
     Landlord if required by this Lease to carry with respect to the Building,
     including but not limited
<PAGE>

                                                                          PAGE 7

     to, indemnifications, Landlord's fire and extended coverage and all
     endorsements thereon, liability insurance incurred in connection with the
     Common Areas, rent interruption, and plate glass insurance policies as such
     relate to the all or any portion of the Building, underlying Land (as
     described in Exhibit A-1), and Landlord's operations. The cost of Insurance
     which is apportionable to Tenant shall relate to insurance which a prudent
     owner would maintain, in type, amount, and deductible.

     (3)  OPERATING EXPENSES.
     For purposes hereof, "Operating Expenses" shall mean all reasonable costs,
     expenses, and disbursements of every kind and nature which Landlord shall
     pay or become obligated to pay in connection with the management,
     operation, maintenance, alteration, replacement and repair of the Building,
     its underlying Land, and of the personal property and fixtures thereof; the
     items of Operating Expenses shall be comparable to market rates at the time
     at which such were incurred by Landlord.

          (a)  Such Operating Expenses shall include, but are not limited to,
          expenditures or obligations relating to:

               (i)  gross salaries and wages, benefits, payroll taxes, social
               security, insurance, and other payments made with respect to
               employees of Landlord and independent contractors engaged in the
               maintenance and/or operation of the Building, except as
               hereinafter provided;
               (ii)  maintenance and repair of Building facia, curtain wall,
               elevators, machinery, equipment, control systems, sprinklers and
               fire control systems, plumbing systems, heating systems,
               ventilating and cooling systems, general systems, and apparatus
               located in or used in connection with such functions for the
               Building, the foregoing shall not include costs attendant to
               replacement of complete systems, elevators, Building facia, or
               curtain wall;
               (iii)  reasonable administrative costs of Landlord for
               bookkeeping, telephone, and other ordinary office expenses
               incurred in operating the Office of the Building, except as
               hereinafter provided;
               (iv)  janitorial, security, gardening, and utility expenses,
               except as hereinafter provided;
               (v)  cost of charges for gas, electricity, air conditioning,
               water, sewer, other utilities, refuse and rubbish removal,
               exterminator services;
               (vi)  legal, accounting, and related professional expenses,
               except as hereinafter provided;
               (vii)  current amortization expenses of capital improvements
               reasonably necessary to reduce the costs of the operation and
               maintenance of the Building. As a limitation to the foregoing
               sentence, the maximum amount of items which may be

                                                                          PAGE 8



          included in Operating Expenses shall be the lesser of (x) the
          reasonable amortization, in the manner Landlord has calculated such
          amortization in the past, of the capital expense incurred to reduce
          said costs of operation and maintenance and (y) the actual savings
          caused by such capital expenditure. The current amortization program
          concerning certain elevator renovations in the Building may be

          not limited to tax on capital gains;

          (iii)   real estate brokerage and leasing commissions or other
          compensation, advertising expenses or any other expenses incurred in
          leasing or selling the Building or any portion of the Building,

          notwithstanding anything to the contrary herein, Taxes shall be
          allocated to the calendar year in which payment is due, without regard
          to whether Taxes are paid in arrears.

(4)  Partial Occupancy
     For purposes of determining adjustments to Operating Expenses for any
Adjustment Year if the Building is not fully rented during all or a portion of
any year subsequent to the Base Year, the Landlord may elect to make an
appropriate adjustment of portions of the Operating Expenses for such year
employing sound accounting and management principles, to determine the amount of
the Operating Expenses that would have been paid or incurred by the Landlord
had the Building


<PAGE>
                                                                         PAGE 10




     been fully occupied and which vary with such occupancy (i.e. cleaning and
     management fees), and the amount so determined shall be deemed to have been
     the amount of Operating Expenses for such year. The Base Year shall be
     adjusted to comport with full occupancy in the same manner as provided
     supra. Landlord agrees to adjust Operating Expenses based on partial
     occupancy in a consistent manner from year to year. In no event shall
     Landlord collect more than its actual expenditure for Operating Expenses by
     means of this Sub-section 3.01(A)(3).

          (a)  "Adjustment Year" means the Calendar Year or any portion thereof
          after the Commencement Date of this Lease for which a Rent Adjustment
          computation is being made.

(B)  Method of Payment of Additional Rent.
     Taxes, Insurance and Operating Expenses are herein collectively referred to
as "Additional Rent Items." On the first day of each month from and after the
Rent Commencement Date, Tenant shall pay to Landlord, together with Tenant's
Monthly Installment of Annual Base Rent, a sum equal to one-twelfth (1/12) of
Landlord's reasonable estimate of Tenant's anticipated Proportionate Share for
that calendar year, as described in subsection 3.02(A), supra. Such monthly
payments shall be applied toward Tenant's Proportionate Share of the actual
Additional Rent Items for the current calendar year, when determined, over the
Base Year.

     Within thirty (30) days after the end of each calendar year Landlord shall
notify Tenant in writing of its actual expenses for the Additional Rent Items
for such calendar year and Tenant's Proportionate Share with a statement in
reasonable detail showing such annual expenses and the amount chargeable to
Tenant, subtracting therefrom the monthly payments made by Tenant for the
calendar year. In the event that Tenant shall have paid to Landlord as
Additional Rent an amount greater than Tenant's Proportionate Share of
Additional Rent Items, Landlord shall credit such excess to Tenant's account for
purposes of Additional Rent for the succeeding calendar year. In the event that
Tenant shall have paid less than Tenant's Proportionate Share of Additional Rent
Items, Tenant shall remit to Landlord such deficiency within thirty (30) days
after receipt of Landlord's invoice and statement therefor. In the event that
Tenant has paid an amount in excess of that due as of the end of the Lease term,
Landlord shall refund such excess to Tenant within thirty (30) days after the
later of (1) the final calculation of actual Operating Expenses for the
applicable year, which will be provided on or about 1 April of the following
year or (2) Tenant fully vacating the Leased Premises. If Annual Base Rent is
abated or apportioned for any reason, the amounts due pursuant to this Section
shall similarly abate or be apportioned. For the calendar years which include
the Rent Commencement Date and the end of the term, Tenant's Proportionate Share
of Additional Rent Items, if any, and its monthly payments therefor, shall be
prorated based upon the number of days after the Rent Commencement Date during
the term within such calendar month, or days prior to the end of the terms
within such month.

(C)  Audit Provisions.
     Tenant reserves the right, upon reasonable notice to Landlord, to make an
audit of all of Landlord's bills and records relating to the Base Year and
Tenant's Proportionate Share of Additional Rent Items and any other charge or
item Tenant is liable for under this Lease. If
<PAGE>
                                                                         PAGE 11


      such audit discloses a discrepancy between the amounts actually payable by
      Tenant and the amounts that Tenant has been charged or billed, Tenant
      shall be allowed to deduct the overpayment from the next succeeding
      minimum Rent payments. In the event that the term has expired, Landlord
      shall refund such to Tenant within thirty (30) days after the later of (1)
      the final calculation of actual Operating Expenses for the applicable
      year, which will be provided on or about 1 April of the following year, or
      as soon as practicable after the close of the previous year, or (2) Tenant
      fully vacating the Leased Premises. If such audit discloses a discrepancy
      in excess of five percent (5%), Landlord shall be obligated to pay all
      reasonable cost actually incurred by Tenant with respect to the audit, the
      cost of which is not to exceed that sum found discrepant by Tenant of its
      proportion.

      (D)  Billing Procedure.
           All billing statements concerning Additional Rent Items shall be
      sent to Tenant at its address indicated in Section 1.01.C.; the Parties
      acknowledge that Landlord is not obligated to provide statements for Base
      Rent.


4.    SECURITY DEPOSIT

4.01  General

      As security for the performance of its obligations under this Lease and
the Workletter, Tenant upon its execution of this Lease shall pay to Landlord a
security deposit ("Security Deposit") in the amount specified in Section
1.01.I. The Security Deposit may be applied by Landlord to cure any default of
Tenant under this Lease, and upon notice by Landlord of such application,
Tenant shall replenish the Security Deposit in full by promptly paying to
Landlord the amount so applied. The Security Deposit may be commingled with
Landlord's other funds and Landlord shall not pay any interest on the Security
Deposit. In the event that the Security Deposit has not been paid by the Tenant
to the Landlord as of the Commencement Date of this Lease, Tenant shall be
prohibited from taking occupancy and or use of the Leased premises; there shall
be no other agreements or promises to the contrary binding upon Landlord unless
such are in writing and executed by the parties hereto. However, the Lease will
remain in effect and all obligations for any Rent obligations will continue.
Within 45 days after the Expiration Date, provided Tenant has vacated the
Leased Premises, Landlord shall return to Tenant the Security Deposit, less any
monetary damages caused by Tenant's default, expenses incurred due to damage to
the Leased Premises or the Building, and such other deductions as may be
provided under this Lease. The Security Deposit shall not be deemed an advance
payment of Rent or measure of damages for any default by Tenant under this
Lease, nor shall it be a bar or defense of any action which Landlord may at any
time commence against Tenant.

4.02  Tendering of Security Deposit and First Month's Rent, and Certain
      Information

      Notwithstanding any provision in this Lease to the contrary, Landlord
shall not be obligated under any covenant or agreement under the Lease until
such time that Tenant has tendered the Security Deposit and the first payment of
monthly Base Rent. Tenant must tender such within seven (7) calendar days after
the execution of the Lease. In the event that Tenant fails to so tender payment,
without notice required of Landlord to Tenant, such failure shall be an Event of
Default under Section 12.01 and Tenant shall be prohibited from taking occupancy
or commencing use of the Leased Premises. However, the Lease will remain in
effect and all Rent obligations will continue.

          and any other such costs as Landlord may expect to incur.

     final and unappealable court decision to have acted recklessly or
     maliciously with respect to its refusal.

     (G)  No Third Party Rights.  The provisions of this clause may be enforced
     solely by the Tenant and Landlord, and are not for the benefit of any other

remodel, decorate, clean or improve the Leased Premises or the Building and no
representation regarding the condition of the Leased Premises or the Building
has been made by or on behalf of Landlord to Tenant except as stated in this
Lease.

8.        ASSIGNMENT AND SUBLETTING

8.01      Consent Required
          Without prior written consent of Landlord, Tenant may not sublease,
assign, mortgage, pledge, hypothecate or otherwise transfer or permit the
transfer of this Lease or the interest of Tenant in this Lease, in whole or in
part, by operation of law or otherwise. The withholding or granting of any such
consent shall be in the sole discretion of the Landlord. If Tenant desires to
enter into any

                                                                         PAGE 17

sublease or assignment of the Leased Premises, Tenant shall deliver written
notice thereof to Landlord, together with financial and other information
sufficient for Landlord to make an informed judgment with respect to such
proposed subtenant or assignee and a copy of the proposed sublease or assignment
agreement at least 20 days prior to the commencement date of the term of the
proposed sublease or assignment. In making its determination of whether to
consent to any proposed sublease or assignment, Landlord may take into
consideration the business reputation and credit worthiness of the proposed
subtenant or assignee; the intended use of the Leased Premises by the proposed
subtenant or assignee; the estimated pedestrian and vehicular traffic in the
Leased Premises and to the Building which would be generated by the proposed
subtenant or assignee; and any other factors which Landlord shall deem relevant;
provided, that Landlord shall in no event be obligated to consider a consent to
any proposed sublease or assignment of the Leased Premises if Tenant is then in
default under this Lease. The withholding or granting of any such consent shall
be in the sole discretion of Landlord. Any approved sublease or assignment shall
be expressly subject to the terms and conditions of this Lease. In the event
that the premises or any portion thereof are sublet or assigned at a rate that
is greater than the Monthly Base Rent set forth herein (the monies collected
from sublessee or assignee in excess of Monthly Base Rent hereinafter "Net
Profits") Tenant shall, on the first day of each month during the term of such
sublease or assignment, pay to Landlord, in addition to the Monthly Installment
of Annual Base Rent due under this Lease, all of the Net Profits due from
assignee or subtenant for each month.

8.02      Exclusion from Lease
          In the event Tenant desires to enter into any sublease or assignment
of the Leased Premises, Landlord shall have the option to exclude from the
Leased Premises covered by this Lease, the space proposed to be sublet or
assignment by Tenant, effective as of the proposed commencement date of
sublease or assignment of said space by Tenant. Landlord may exercise said
option by giving Tenant written notice thereof within forty-five (45) days after
receipt by Landlord of Tenant's notice of the proposed sublease or assignment.
In the event Landlord exercises said option, Tenant shall surrender possession
of the proposed space subject to sublease or assignment to Landlord on the
effective date of exclusion of said space from the Leased Premises covered by
this Lease, and neither party hereto shall have any further rights or
liabilities with respect to said space under this Lease. Effective as of the
date of exclusion of any portion of the Leased Premises covered by this Lease
pursuant to this paragraph, (i) the Monthly Installments of Annual Base Rent
specified in subsection 1.01.F shall be reduced in the same proportion as the
number of square feet of rentable area contained in the portion of the Leased
Premises so excluded bears to the number of square feet of rentable area
contained in the Leased Premises prior to such exclusion, and (ii) the rentable
area of the Leased Premises specified in subsection 1.01.H and Tenant's
Proportionate Share specified in subsection 1.01.G.2. shall be decreased in the
same proportion that the Leased Premises has been decreased, for all purposes
under this Lease.

8.03      No Release
          In the event of any approved sublease or assignment, Tenant shall not
be released or discharged from any liability, whether past, present or future,
under this Lease, including any renewal term of this Lease. For purposes of
this Section 8, an assignment shall be deemed to include a change in the
majority control of Tenant, if Tenant is a partnership or a corporation whose
shares of stock are not traded publicly. If Landlord grants consent to such
sublease or assignment, Tenant shall pay all of the reasonable attorneys' fees
of Landlord incurred with respect to such assignment
<PAGE>


                                                                         PAGE 18


or sublease. In addition, if Tenant has any options to extend the term of this
Lease such, options shall not be available to any subtenant, directly or
indirectly.

9.    MAINTENANCE

9.01  Landlord's Maintenance
      Landlord shall maintain and make necessary repairs to foundations, roofs,
exterior walls, marquees, and the structural elements of the Building, and,
subject to the provisions of Section 15, the electrical, plumbing, heating,
ventilation and air conditioning systems of the Building and the public
corridors, washrooms and lobby of the Building, except that:

      (A) Landlord shall not be responsible for the maintenance or repair of any
      such systems which are located within the Leased Premises or which are
      supplemental or special to the Building's standard systems or floor or
      wall coverings or fixtures in the Leased Premises; and

      (B) the cost of performing any of said maintenance or repairs caused by
      the negligence of Tenant, its employees, agents, servants, licensees,
      subtenants, contractors or invitees, shall be paid by Tenant, except to
      the extent of insurance proceeds, if any, actually collected by Landlord,
      as Additional Insured, with regard to the damage necessitating such
      repairs. As used in this Section 9.01, the "exterior walls" do not include
      interior glass, windows, doors, window sashes or frames, door frames or
      office fronts of the Leased Premises.

9.02  Tenant's Maintenance

      Tenant, at its expense, shall keep and maintain the Leased Premises in
good order, condition and repair and in accordance with all applicable legal,
governmental and quasi-governmental statutes, requirements, ordinances and
rules, including but not limited to the Board of Fire Underwriters and the
Americans with Disabilities Act, as such may be amended or replaced from time to
time. Tenant shall promptly and adequately, under the control and supervision of
Landlord as provided under Article 10, infra, (A) repair all damage to the
Leased Premises, (B) replace or repair all damaged or broken glass in the
interior of the Leased Premises, fixtures or appurtenances, and (C) repair all
damage to the Building caused by Tenant's employees, contractors, invitees, or
agents. If Tenant fails to perform any of its obligations set forth in this
Section 9.02, Landlord may, in its sole discretion, perform the same, and Tenant
shall pay to Landlord the cost thereof upon demand. In the event that Landlord
provides its approval, if required or volunteered, such shall create no
responsibility or liability on the part of the Landlord for the completeness,
design, sufficiency, or compliance with the afore-mentioned laws, regulations,
and requirements.

10.   ALTERATIONS AND IMPROVEMENTS

10.01 Tenant's Alterations
      Tenant shall not, without the prior written consent of Landlord, make or
cause to be made any alterations, improvements, additions, installations, or
decorations in or to the Leased Premises. If Landlord so consents, before
commencement of any such work or delivery of any materials to the Leased
Premises or the Building, Tenant shall furnish to Landlord for approval:
architectural plans and specifications, names and addresses of all contractors
and subcontractors, copies of all contracts,


<PAGE>
                                                                         PAGE 19

affidavits from engineers acceptable to Landlord stating that the alterations
will not in any way adversely affect the mechanical, heating, ventilation, air
conditioning, and the electrical systems in the Building, necessary permits and
licenses, certificates of insurance and instruments of indemnification against
any and all claims, costs expenses, damages and liabilities which may arise in
connection with such work, and such other documents reasonably requested by
Landlord, all in such form and amount as may be satisfactory to Landlord.
Landlord shall respond in writing to Tenant within fifteen (15) days after
receipt of any information necessitating the consent or approval of Landlord,
indicating reasons for its refusal to consent. In addition, prior to
commencement of any such work or delivery of any materials into the Leased
Premises, Tenant shall provide Landlord with appropriate evidence of Tenant's
ability to pay for such work and materials in full, and if requested by
Landlord, shall deposit with Landlord at such time such security for the
payment of said work and materials as Landlord may require. Whether or not
Tenant furnishes the foregoing, Tenant agrees to indemnify, defend and hold
Landlord, the beneficiaries of Landlord, the parties of such beneficiaries, any
mortgage of the building, the Manager and their respective directors, offices,
agents and employees (hereinafter for convenience sometimes collectively
referred to as the "Landlord Indemnitees") harmless against all claims and
liabilities of every kind, nature and description which may arise out of or in
any way be connected with such work, including, but not limited to,
environmental related claims and/or liabilities. All such work shall be done
only by contractors or mechanics approved by the Landlord and at such time and
in such manner as Landlord may from time to time designate. Tenant shall pay
the cost of all such work and the cost of decorating the Leased Premises and
the Building occasioned thereby. Upon completion of such work, Tenant shall
furnish Landlord with Contractors' affidavits and full and final waivers of
lien and receipted bills covering all labor and materials expended and used in
connection therewith together with any governmental acceptances required by
applicable law. All such work shall be performed and completed in accordance
with all applicable legal, governmental and quasi-governmental statutes,
requirements, ordinances and rules, including but not limited to the Board of
Fire Underwriters, federal and state EPA, ADA, and all requirements of
applicable insurance companies, as such may be amended or replaced from time to
time. In the event that Landlord provides its approval, if required or
volunteered, such shall create no responsibility or liability on the part of
the Landlord for the completeness, design, sufficiency, or compliance with the
afore-mentioned laws, regulations, and requirements. All such work shall be
done in a good and workmanlike manner and with the use of good grades of
materials. Tenant shall pay Landlord a fee based on a fifteen percent (15%)
mark-up of the cost of the work to be completed for coordinating and
supervising construction operations in connection with such work. In no event
shall such supervision by Landlord nor shall any approvals given by Landlord
under this Lease constitute any warranty by Landlord to Tenant of the adequacy
of the design, workmanship of quality of such work or materials for Tenant's
intended use or impose any liability upon Landlord in connection with the
performance of such work. All alterations, improvements, temporary or
permanent, additions and installations to or on the Leased Premises, whether
placed there by Landlord or Tenant, shall, unless Landlord requests their
removal, become part of the Leased Premises at the time of their installation
and shall remain in the Leased Premises at the expiration or termination of
this Lease, or termination of Tenant's right of possession of the Leased
Premises, without compensation or credit to Tenant.

10.02 Liens

     Tenant shall not permit any lien or claim for lien of any mechanic, labor
or supplier or any other lien to be filed against the Building, the Land (as
hereinafter defined), the Leased Premises, or
<PAGE>

                                                                         PAGE 20

any part thereof arising out of work performed, or alleged to have been
performed by, or at the direction of, or on behalf of Tenant. If any such lien
or claim for lien is filed, Tenant within 14 days after notice of such lien or
claim for lien, shall have such lien or claim for lien released of record or
shall deliver to Landlord either:

      (A)  a bond in form, content, amount and issued by surety, satisfactory to
      Landlord, indemnifying Landlord, the Indemnitees and others designated by
      Landlord against all costs and liabilities resulting from such lien or
      claim for lien and the foreclosure or attempted foreclosure thereof, or

      (B)  endorsements to the title policies of Landlord and Landlord's
      mortgagee "insuring over" such liens satisfactory to Landlord and
      Landlord's mortgagee, respectively.

If Tenant fails to have such lien or claim for lien so released or to deliver
such bond or title endorsement to Landlord, the Landlord, without investigating
the validity of such lien, may pay or discharge the same, and Tenant shall
reimburse Landlord upon demand for the amount so paid by Landlord, including
Landlord's expenses and attorneys' fees.

10.03 Landlord's Work

      It is further agreed that this Lease is made by the Landlord and accepted
by the Tenant with the distinct understanding and agreement that the Landlord
shall have the right and privilege to make and build additions to the Building
of which the Leased Premises are a part, and make such installations,
alterations (which alterations may include alteration or replacement of
freon-based HVAC equipment), replacements and repairs (including the erection of
scaffolding and barricades) to said Building interior and exterior as it may
deem wise and advisable without any liability to the Tenant therefor. During any
disruption caused by Landlord's work, this Lease and all obligations, including
the obligation to pay Rent, shall continue in full force and effect. In no event
shall any Landlord Indemnitee be liable for any loss, cost, expense, demand,
damage or injury to or suffered by Tenant, its employees, agents, invitees,
representatives, heirs, successors, assigns, or any other person or entity
claiming by, through or under the foregoing, or any property, real or person,
owned by any of the foregoing, in connection with such alteration, installation,
repairing and/or replacement of Building systems and or any asbestos removal,
abatement or containment occasioned thereby. Such work performed by Landlord
shall be at its expense. Landlord shall exercise reasonable efforts to minimize
disruptions to Tenant's operations and conduct such work during other than
regular business hours.

11.   WAIVER OF CLAIMS AND INDEMNITY

11.01 Tenant

      (A)  Waiver of Claims

           To the extent permitted by law, Tenant releases the Landlord
      Indemnitees from, and waives all claims for, damage to property sustained
      by the Tenant or any occupant of the Leased Premises resulting from any
      act or neglect of Landlord or its employees, agents or servants. The
      foregoing waiver of claims by Tenant in favor of Landlord shall be limited
      to the greater of (1) the extent insurance coverage is maintained by
      Tenant or (2) the insurance coverage which would be maintained by a
      reasonably prudent person in the position of

<PAGE>

              Tenant.

              (B)    Indemnification

                     Tenant agrees to indemnify and hold the Landlord
Indemnities harmless against any and all claims, demands, costs and expenses for
injury to person or property, including reasonable attorney's fees for the
defense thereof, arising from Tenant's occupation of 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 of negligence of Tenant, its agents, servants, employees
or invitees, in or about the Building, Leased Premises, or at other locations,
subject to the waiver provision infra. In case of any action or proceeding
brought against the Indemnitees by reason of such claim, upon notice from
Landlord, Tenant covenants to defend such action or proceeding by counsel
reasonably satisfactory to Landlord.

11.02         Landlord Indemnification

              Landlord agrees to indemnify and hold the Tenant Indemnitees
harmless against any and all claims, demands, costs and expenses for injury to
person or property, including reasonable attorney's fees for the defense
thereof, arising 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, servants, employees or invitees, in or about the Building
or at other locations, subject to the waiver provision supra. In case of any
action or proceeding brought against the Indemnitees by reason of any such
claim, upon notice from Tenant, Landlord covenants to defend such action or
proceeding by counsel reasonably satisfactory to Tenant.


12.           LANDLORD'S REMEDIES

12.01         Events of Default

              Each of the following shall constitute a breach of this Lease by
Tenant and, in the event that Tenant fails to cure said breach within the
applicable period, if any, an Event of Default by Tenant:

              (A)  Tenant fails to pay any Monthly Installment of Annual Base
Rent or other payment of Rent when due;

              (B)  Tenant fails to observe or perform any of the other
covenants, conditions or provisions of this Lease or under the Workletter to be

periods provided in this Lease or, if not so provided, within fifteen (15) days
after written notice thereof to Tenant.

              (C)  the interest of Tenant in this Lease is levied upon under
execution or other legal process and such action is not dismissed within
fifteen (15) days thereof;

              (D)  a petition is filed by or against Tenant to declare Tenant

<PAGE>

                                                                         PAGE 22

capital structure or upon the dissolution of Tenant, and such action is not

        (E)   Tenant is declared insolvent by law or any assignment of Tenant's
property is made for the benefit of creditors;

        (F)   a receiver is appointed for Tenant of Tenant's property, and such
action is not dismissed within fifteen (15) days thereof; or

        (G)   Tenant abandons the Leased Premises.

12.02   Landlord's Remedies
        In the event of any default under this Lease by Tenant, Landlord, at
its option, without further notice or demand to Tenant, may, in addition to all
other rights and remedies provided in this Lease, at law or in equity exercise
the following rights:

         (A)   Landlord shall have the immediate right of re-entry and may
remove all persons and property from the Leased Premises and such property may
be removed and stored in a public warehouse at the cost of, and for the account
of Tenant, after service of notice and resort to legal process but without
being deemed guilty of trespass, or becoming liable for any loss or damages
which may be occasioned thereby;

         (B)   Landlord may, from time to time, without terminating this Lease,
and without releasing Tenant in whole or part from Tenant's obligation to pay
Rent and perform any of the covenants, conditions and agreements to be
performed by Tenant as provided in this Lease, make such alterations and
repairs as may be necessary in order to relet the Leased Premises. Landlord
shall exercise reasonable business judgment, including but not limited to
consideration of market conditions and the type and reputation of the proposed
replacement tenant to relet the Leased Premises or any part thereof for such
period (which may be for a term extending beyond the Term of this Lease), at
such rental rates, and upon such other terms and conditions as Landlord in its
sole discretion may deem advisable; upon each such reletting all rent received
by the Landlord from such reletting shall be applied first, to the payment of
any indebtedness other than the Rent due hereunder from Tenant to Landlord,
including but not limited late fees and interest; second, to the payment of any
costs and expenses of such reletting, including brokerage fees and attorneys'
fees and of costs of such alterations and repairs; third, to the payment of
Rent due and unpaid hereunder; and the residue, if any, shall be held by
Landlord and applied in payment of future Rent as the same may become due and
payable hereunder. If such rent payments received form reletting during any
month be less than that to be paid during that month hereunder, Tenant shall
pay any such deficiency to Landlord. Such deficiency shall be calculated and
paid monthly. Landlord may apply its reasonable criteria as to the
acceptability of a prospective tenant for said relet, including but not limited
to its financial status, business reputation and activity, proposed use of the
premises, violation of exclusive rights granted others at the time, and
character of tenant population. Notwithstanding any such reletting without
termination, Landlord may at any time thereafter elect to terminate this Lease
for such previous breach;
<PAGE>
                                                                         PAGE 23

          (C)  Landlord may terminate this Lease in which event it may recover
from Tenant all damages it may incur by reason of such breach, including the
cost of recovering the Leased Premises, reasonable attorneys' fees, and the
amount of Rent and charges equivalent to Rent reserved in this Lease for the
remainder of the stated Term, all of which amounts shall be immediately due and
payable from Tenant to Landlord. Landlord shall use good faith efforts to
mitigate damages in the event of Tenant's default.

          The Landlord's re-entry, demand for possession, a notice that the
tenancy hereby created will be terminated on the date therein named, institution
of an action of forcible detainer or ejectment or the entering of a judgment
for possession in such action, or any other act or acts resulting in the
termination of Tenant's right to possession of the Leased Premises shall not
relieve Tenant from Tenant's obligation to pay the Rent hereunder during the
balance of the Term or any extension thereof, except as herein expressly
provided. The Landlord may collect and receive any Rent due from Tenant, and
the payment thereof shall not constitute a waiver of default or affect any
notice or demand given, suit instituted or judgment obtained by Landlord, or be
held to waive, affect, change, modify or alter the rights or remedies which
Landlord has in equity or at law or by virtue of this Lease.

12.03     Waiver of Notice
          Tenant hereby expressly waives the service of any notice of any
election of remedies made by Landlord under this Section 12, demand for payment
of Rent or for possession, except any form of demand and notice (including, but
not limited to a five-day notice) prescribed by any applicable statute or other
law.

13.       SURRENDER OF PREMISES
13.01     General
Upon expiration or termination of this Lease or termination of Tenant's right
of possession of the Leased Premises, or any part thereof, for any reason
whatsoever, Tenant shall surrender and vacate the Leased Premises immediately
and deliver possession thereof to Landlord in a clean, good and tenantable
condition, ordinary wear and tear excepted, including removal of all personal
property not permanently affixed. For purposes hereof, the term "personal
property" shall include, but is not limited to, office furniture and equipment,
safes, and supplies, all such personal property not being affixed to the
ceiling, floor, or walls of the Leased Premises. With regard to any
improvements which were not authorized by Landlord, at Landlord's option,
Tenant shall remove such improvements and return the Leased Premises to their
original condition, ordinary wear and tear excepted, or abandon such leasehold
improvements to Landlord, title thereto passing to Landlord. For purposes
hereof, the term "leasehold improvements" shall include, but is not limited to,
original build-out, Landlord-authorized Tenant's subsequent improvements,
unauthorized improvements, and Landlord work performed at Tenant's request. In
the event that Tenant fails to remove all personal property, Landlord may
remove such at Tenant's expense; in such circumstance, Tenant abandons such
personal property to Landlord, title thereto passing to Landlord free and clear
of all encumbrances and Tenant indemnifying Landlord therefor. Tenant shall
additionally comply with such Rules and Regulations as may apply to moving out
of the Leased Premises and Building.

13.02     Removal of Certain Chemicals and Related Equipment
<PAGE>


                                                                         PAGE 24


        (A) In addition, upon termination of this Lease or Tenant's right of
        possession of the Leased Premises, whether by lapse or time or
        otherwise, Tenant shall remove any and all equipment situated on the
        Leased Premises, which Tenant has installed therein (regardless of
        Landlord's prior written consent therefor), which contain or use freon,
        chlorofluorocarbons, or any material which is deemed hazardous or
        regulated under applicable municipal ordinances and state and federal
        statutes, regulations, or other governmental restrictions. Such removal
        shall be done in accordance with all legal requirements and industry
        practices by a qualified contractor, and the procedures of Section
        10.01 hereof with respect to alterations shall apply. Specifically, but
        without limitation, all plans and drawings for removal of such equipment
        and/or materials and all contractors to be employed in connection
        therewith shall be approved by Landlord, the work shall proceed
        expeditiously and in good and workmanlike manner, and Landlord and its
        representatives shall have full and unlimited access to the Leased
        Premises to ensure that all proper procedures for removal of such
        materials and/or equipment are being followed and to assure that the
        Building and Building systems are not being affected and no asbestos
        problem is being created as a result of such removal.

        (B) Tenant, at its sole cost and expense, shall be required to repair
        and restore the Leased Premises and the Building and any part thereof
        which may be damaged as a result of the removal of the items described
        in subsection 13.02(A), no matter how extensive such damage may be
        including, but not limited to, any asbestos abatement, containment or
        removal which may be necessitated as a result of such work. Tenant
        agrees to indemnify, defend and hold harmless the Indemnitees from and
        against any and all losses, costs, expenses, damages, liability, claims,
        demands, causes of action and fees (including, but not limited to, any
        asbestos abatement, containment or removal which may be necessitated as
        a result of such work). Tenant agrees to indemnify, defend and hold
        harmless the Indemnitees from and against any and all losses, costs,
        expenses, damages, liability, claims, demands, causes of action and fees
        (including, but not limited to, reasonably attorneys' fees) of whatever
        nature which may arise from or be attributable to the work required to
        be done hereunder, including, but not limited to, tenant losses for
        business interruption and contamination cleanup. In the event Tenant
        fails or refuses, for any reason whatsoever, to perform or cause to be
        performed the aforesaid removal, Landlord shall be entitled to cause
        such work to be done without affecting or waiving any liability or
        responsibility of Tenant therefor.

13.03.  Personal Property
        Upon any termination which occurs other than by reason of Tenant's
default, Tenant shall be entitled to remove from the Leased Premises all movable
personal property of Tenant, provided Tenant immediately shall repair all damage
resulting from such removal and shall restore the Leased Premises to a
tenantable condition. In the event possession of the Leased Premises is not
immediately delivered to Landlord or if Tenant shall fail to remove all of
Tenant's movable personal property, as aforesaid, Landlord may remove any of
such property therefrom without any liability to Tenant. Landlord shall give
written notice to Tenant of the existence of such personal property and Tenant
shall retrieve such from Landlord, wherever located, within thirty (30) days
thereafter. All movable personal property which may be removed from the Leased
Premises by Landlord shall be conclusively presumed to have been abandoned by
Tenant and title thereto shall pass to Landlord,

<PAGE>

                                                                         PAGE 25

free and clear of all encumbrances and Tenant indemnifying Landlord therefor,
without any cost or credit therefor and Landlord may, at its option and at
Tenant's expense, store and/or dispose of such property.

14.    HOLDING OVER

       If Tenant retains possession of the Leased Premises after the Expiration
Date of the Term set forth in Section 1.01.E.5, or the termination or
expiration of this Lease for any other reason, Tenant shall pay Landlord double
the Monthly Base Rent, for the final month of the Term for each month or
partial month after the expiration or termination of this Lease. The provisions
of this Article shall not constitute a waiver by Landlord or any re-entry rights
of Landlord hereinbefore or by law provided. Payment by Tenant of monies
pursuant to this Article shall not be construed as liquidated damages or a
limitation upon Landlord's remedies in the event that Landlord is reasonably
unable to consummate a transaction with a third party prospective tenant due to
Tenant's unauthorized holdover.

15.    DAMAGE BY FIRE OR OTHER CASUALTY

15.01  Substantial Untenantability.

       If the Building or the Leased Premises are made substantially
untenantable by fire or other casualty, Landlord may elect either to:

       (A)  terminate this Lease as of the date of the fire or other casualty
       by giving Tenant written notice thereof within ninety (90) days after
       said date; or

       (B)  proceed to repair or restore the Building or the Leased Premises,
       other than leasehold improvements and personal property paid for or
       installed by Tenant, and this Lease shall remain in full force and
       effect.

If Landlord elects to proceed with subsection (B) above, Landlord shall
notify Tenant thereof within ninety (90) days after the date of such fire or
other casualty, which notice shall contain Landlord's reasonable estimate of
the time required to substantially complete such repair or restoration. In the
event such estimate indicates that the time so required will exceed two hundred
fifty (250) days from the date of the casualty, then Tenant shall have the
right to terminate this Lease as of the date of such casualty by giving written
notice thereof to Landlord not later than twenty (20) days after the date of
Landlord's notice. If Landlord's estimate indicates that the repair or
restoration can be substantially completed within said two hundred fifty (250)
days from the date of the casualty, or if Tenant fails to exercise its right to
terminate this Lease, as aforesaid, this Lease shall remain in force and effect.

15.02  Insubstantial Untenantability

       If the Leased Premises or the Building are damaged by fire or other
casualty but neither is rendered substantially untenantable, then Landlord
shall proceed to repair and restore the Building or the Leased Premises, other
than the leasehold improvements and personal property paid for or installed by
Tenant, unless such damage occurs during the last twelve (12) months of the
Term, in which event Landlord shall have the right to terminate this Lease as
of the date of such fire or other casualty by giving written notice thereof to
Tenant within thirty (30) days after the date of such fire

or other casualty.

15.03  Leasehold Improvements

       In the event the Leased Premises or the Building are damaged by fire or
other casualty, and this Lease is not terminated, Tenant shall proceed to
repair and restore all leasehold improvements and personal property paid for or
installed by or for the benefit of Tenant, in accordance with the provisions of
Section 10 hereof. In the event such leasehold improvements and/or personal
property use or contained chlorofluorocarbons and substitute or alternative
materials and/or equipment are then commercially available, Tenant shall alter
and/or replace such leasehold improvements and/or personal property in
accordance with the terms and provisions of this Lease.

15.04  Rent Abatement

       Except for the negligence or willful act of Tenant or its agents,
employees, contractors or invitees, if all or any part of the Leased Premises
are rendered substantially untenantable by fire or other casualty and this Lease
is not terminated, Monthly Base Rent shall abate for that part of the Leased
Premises which is untenantable on a per diem basis from the date of the fire or
other casualty until Landlord has substantially completed the repair and
restoration work in the Leased Premises which it is required to perform,
provided, that as a result of such fire or other casualty, Tenant does not
occupy the portion of the Leased Premises which is untenantable during such
period.


16.    EMINENT DOMAIN

16.01  Taking of Whole or Substantial Part

       In the event the whole or any substantial part of the Land, Building or
Leased Premises is taken or condemned by any competent authority for any public
use or purpose (including a deed given in lieu of condemnation), this Lease
shall terminate as of the date title vests in such authority, and Rent shall be
apportioned as of said date.

16.02  Taking of Part

       In the event that less than all or a substantial part of the Building or
Leased Premises, or the entirety thereof for a temporary period, is taken or
condemned by any competent authority for any public use or purpose (including a
deed given in lieu of condemnation) and this Lease is not terminated pursuant to
Section 16.01, the Lease shall be amended to reduce Rent, and otherwise reflect
the decrease in space within the Leased Premises, in the same ratio as the
number of square feet of rentable area in the Leased Premises so taken or
condemned bears to the number of square feet of rentable area then leased by
Tenant. Landlord, upon receipt and to the extent of the award in condemnation or
proceeds of sale, shall make necessary repairs and restorations (exclusive of
Tenant's leasehold improvements and personal property paid for or installed by
or for the benefit of Tenant, which shall be restored in accordance with the
provisions of Section 15.03 hereof) to restore the Leased Premises remaining to
as near its former condition as circumstances will permit, and to the Building
to the extent necessary to constitute the portion of the Building not so taken
or condemned as a complete architectural unit. In the event of a partial taking
or condemnation of the Leased Premises and/or the Building as herein described,
the rentable area of the Leased Premises then leased by Tenant and/or the
rentable area of the Building as specified in this Lease, respectively, shall be
reduced for all purposes under this Lease by the number of square feet of
rentable area of the Leased Premises and/or the Building as specified in this
Lease, respectively, so
<PAGE>

                                                                         PAGE 27

taken or condemned. Notwithstanding the foregoing, if as a result of any taking
including a governmental order that the grade of any street or alley adjacent to
the Building is to be changed and such taking or change of grade makes it
necessary or desirable to substantially remodel and restore the Building,
Landlord shall have the right to terminate this Lease upon 90 days prior written
notice.

16.03 Compensation

      Landlord shall be entitled to receive the entire price or award from any
such sale, taking or condemnation without any payment to Tenant, and Tenant
hereby assigns to Landlord Tenant's interest, if any, in such award; provided,
however, Tenant shall have the right separately to pursue against the condemning
authority an award in respect of the loss, if any, to leasehold improvements
paid for by Tenant without any credit or allowance from Landlord or deduction
from the Landlord's award.

17.   TENANT'S INSURANCE

17.01 Minimum Insurance

      Tenant, at Tenant's expense, agrees to maintain in force during the Term:

      (A)  Comprehensive General Liability Insurance on an occurrence basis with
      minimum limits of liability in an amount of One Million Dollars
      ($1,000,000) for bodily injury, personal injury or death to any one person
      and Three Million Dollars ($3,000,000) for bodily injury, personal injury
      or death to more than one person and Five Hundred Thousand Dollars
      ($500,000) with respect to damage to property, including water and
      sprinkler damage; and

      (B)  Fire Insurance, with extended coverage, vandalism and malicious
      mischief endorsements, in an amount adequate to cover the full replacement
      value of all leasehold improvements and all fixtures, contents and wall
      and floor coverings in the Leased Premises.

17.02 Additional Insureds; Endorsements

      The policy referred to in 17.01 shall name the Landlord Indemnitees as
additional insureds and shall not provide for deductible amounts in excess of
One Thousand Dollars ($1,000). Each policy referred to in 17.01 shall be issued
by one or more responsible insurance companies licensed to do business in
Illinois and reasonably satisfactory to Landlord and shall contain the following
provisions and endorsements:

      (A)  that such insurance may not be canceled or amended without thirty
      (30) days' prior written notice to the Landlord;

      (B)  an express waiver of any right of subrogation by the insurance
      company against the Landlord Indemnitees; and

      (C)  that the policy shall not be invalidated should the insured waive in
      writing prior to a loss, any or all rights of recovery against any party
      for losses covered by such policies.

17.03 Certificates

      Tenant shall deliver to Landlord, certificates of insurance of all
      policies and renewals thereof

<PAGE>
                                                                         PAGE 28



to be maintained by Tenant hereunder, not less than ten (10) days prior to the
Commencement Date and not less than ten (10) days prior to the expiration date
of each policy.

17.04  Waiver of Subrogation
     Notwithstanding any provision in this Lease to the contrary, but subject to
Article IX concerning Tenant's maintenance and repair obligations, the parties
release each other, and their respective authorized representatives, from any
claims for damage to any person or to the Leased Premises and the Building, and
to the fixtures, personal property, Tenant's improvements, and alterations of
either Landlord or Tenant in or on the Leased Premises and the Building that are
caused by or result from risks insured against under any insurance policies
carried by the parties and in force at the time of any such damage.

     Since this mutual waiver will preclude the assignment of any such claim by
subrogation (or otherwise) to an insurance company (or any other person),
Landlord and Tenant each agree to give each insurance company which has issued,
or in the future may issue, its policies of fire, extended coverage or material
damage insurance written notice of the terms of this mutual waiver, and to have
such insurance policies properly endorsed if necessary, to prevent the
invalidation of any of the coverage provided by such insurance policies by
reason of such mutual waiver.

18.    RULES AND REGULATIONS
18.01  General
     Tenant agrees for itself and for its subtenants, employees, agents, and
invitees to comply with the following rules and regulations and with all
reasonable modifications and addition thereto which Landlord may make time to
time, which shall neither conflict with an express provision hereof, materially
interfere with Tenant's business operations, nor materially increase Tenant's
monetary costs; Landlord shall give Tenant written notice of any changes to
Rules and Regulations;

     (A)  Move-in, Move-out Rules.

     following:

          (1)  Move-ins.
               Tenant may not move into its Leased Premises until the Security

          Landlord.

          (2)  Move-outs.
               Tenant may not schedule a move-out unless it has a fully funded

          then Tenant shall pre-pay additional costs (if any) for extra-hours
          elevator use and other Landlord services, and shall guarantee the
          payment of any other items which Landlord may reasonably charge.

          Tenant shall schedule with the Office of the Building the date and

        circumstances.

        within the Leased Premises which is visible from the public corridors
        within the Building shall be installed in such manner and be of such
        character and style as Landlord shall approve in writing.

        (C)  Tenant will not make or permit to be made any use of the Leased
        Premises which, directly or indirectly is forbidden hereunder or by

        the premium cost of any policy of insurance carried on the Building or
        covering its operations. Tenant shall not do, or permit to be done, any
        act or thing upon the Leased Premises which will be in conflict with

        rules, regulations or requirements of the Illinois Inspection and Rating

        Department, Illinois Inspection and Rating Bureau, Fire Insurance Rating
        Organization or other authority having jurisdiction and then only in
        such quantity and manner of storage as not to increase the rate of fire,

        which is explosive or inherently dangerous is not allowed in the
        Building;

        (D)  Tenant shall not use any picture or likeness of the Building in any

        company or corporation by which the Building may be known or named;

        (F)  Sidewalks, entrances, passages, courts, corridors, halls, elevators
        and stairways in and about the Leased Premises shall not be obstructed
        nor shall objects be placed against glass partition, doors or windows
        which would be unsightly from the Building's corridors or from the
        exterior of the Building;

        (I)  Tenant shall not waste electricity, water or air conditioning and

<PAGE>

                                                                         PAGE 30


      with Landlord to assure the most effective and efficient operation of the
      Building's heating and air conditioning systems. All controls shall be
      adjusted only by authorized building personnel; Tenant shall lower and
      adjust the venetian blinds on the windows in the Leased Premises, if such
      lowering and adjustment reduces the sun load;

      (J)  No locks or similar devices shall be attached to any door except by
      Landlord and Landlord shall have the right to retain a key to all such
      locks;

      (K)  Tenant assumes full responsibility of protecting the Leased Premises
      from theft, robbery and pilferage; the Indemnitees shall not be liable for
      damage thereto or theft or misappropriation thereof. Tenant hereby
      acknowledges and agrees that security services contracted and/or devices
      installed or otherwise effected by Landlord are for the sole purpose of
      safeguarding Landlord's property and interests and neither Tenant nor any
      other person shall be deemed a beneficiary thereof or to rely thereon.
      Except during Tenant's normal business hours, Tenant shall keep all doors
      to the Leased Premises locked and other means of entry to the Leased
      Premises closed and secured. All corridor doors shall remain closed at all
      times. Tenant shall be solely responsible for the actions of its employees

      obligation, without opportunity for cure by Tenant, to exclude the
      Tenant's employee or independent contractor from the Building and deny any
      and all access thereto to such person. Such right shall be in addition to
      any and all rights Landlord may have under this Lease and law;

      (L)  Only machinery or mechanical devices of a nature directly related to
      Tenant's ordinary use of the Leased Premises shall be installed, placed or
      used in the Leased Premises. In the event that Tenant desires telegraphic,
      telephones, burglar alarms or other electronic mechanical devices, the
      Landlord will, upon request, direct where and how connections and all
      wiring for such services shall be introduced and run. Without such
      directions, no boring, cutting, or installation of machinery, mechanical
      devices, wires or cables is permitted and the installation and use of all
      such is subject to the other rules contained in this Section 18, general
      construction practices and rules of the Building, and the other portions
      of this Lease;

      (M)  Except with the prior approval of Landlord, all cleaning, repairing,

      the Leased Premises shall be done only by authorized Building personnel;

      (N)  Safes, furniture, equipment, machines and other large or bulky
      articles shall be brought to the Building and into and out of the Leased
      Premises at such times and in such manner as the Landlord shall direct
      (including the designation of elevator) and at Tenant's sole risk and
      cost. Prior to Tenant's removal of any such articles from the Building,
      Tenant shall obtain written authorization of the Office of the Building
      and shall present such authorization to a designated employee of Landlord;

<PAGE>


                                                                         PAGE 31


        (O)  Tenant shall ascertain from Landlord the maximum amount of
        electrical current which can safely be used in the Leased Premises,
        taking into account the capacity of the electric wiring of the Building
        and the Leased Premises and the needs of other tenants, and shall not
        use more than such safe capacity. Landlord's consent to the installation
        of the electrical equipment shall not relieve Tenant from the obligation
        not to use more electricity than such safe capacity;

        (P)  To the extent permitted by law, Tenant shall not permit picketing
        or other union activity or distribution of written material involving
        its employees in the Building, except in those locations and subject to
        time and other limitation as to which Landlord may give prior written
        consent;

        (Q)  Tenant shall not cook, otherwise prepare or sell any food or
        beverages, including but not limited to vending machines, in or from the
        Leased Premises or use the Leased Premises for housing accommodations or
        lodging or sleeping purposes, except use of microwave ovens, coffee
        makers, and/or warmers in Tenant's kitchen area. Notwithstanding the
        foregoing, should Tenant desire vending machines in the Leased Premises,
        then Landlord's vendor shall have the option to install and maintain
        vending machines in the Leased Premises, subject to Tenant's request for
        such, at competitive market rates, and applicable federal contracting
        requirements under which Tenant may be obligated. Under all
        circumstances, vending machines shall be limited to two (2) in number;

        (R)  Tenant shall not permit the use of any apparatus for sound
        production or transmission in such manner that the sound so transmitted
        or produced shall be audible or vibrations therefrom shall be detectable
        beyond the Leased Premises; nor shall Tenant permit any noise or odor
        that is objectionable to other occupants of the Building to emanate from
        the premises, and shall not create or maintain a nuisance thereon, and
        shall not do any act tending to injure the reputation of the Building.

        (S)  Tenant shall not place a load upon any floor of the Leased Premises
        exceeding the floor load capacity for which such floor was designed or
        allowed by law to carry;

        (T)  No floor covering shall be affixed to any floor in the Leased
        Premises by means of glue of other adhesive without Landlord's prior
        written consent.

18.02   Landlord Not Liable for Violations
        Landlord shall not be responsible for any violation of the foregoing
rules and regulations by other tenants of the Building and shall have no
obligation to enforce the same against other tenants. Nothing in this Lease
shall be construed to impose upon the Landlord any duty or obligation to enforce
provisions of this Section 18 or any rules and regulations hereafter adopted, or
the terms, covenants or conditions of any other lease as against any other
tenant, and Landlord shall not be liable to the Tenant for violation of the same
by any other tenant, its servants, employees, agents, visitors or licensees,
unless such violation constitutes a default by Landlord under this Lease.
Notwithstanding the foregoing, Landlord shall take commercially reasonable
efforts to address rules violations by other tenants which substantially
interfere with Tenant's operations.

       In addition to all other liabilities, rights and remedies for breach of
any covenant of this Section 18, the Tenant shall pay to the Landlord all
damages caused by such breach and shall also pay to the Landlord as additional
rent an amount equal to any increase in insurance premium or premiums caused by
such breach. Any violation of this Section 18 may be restrained by injunction.
The Tenant shall be liable to the Landlord for all damages resulting from
violation of any of the provisions of this Section 18, regardless of whether the
Tenant took corrective action during any cure period.

       Landlord shall have the following rights exercisable without notice
(except as expressly provided to the contrary in this Lease), without liability

21.    RELOCATION OF TENANT

       At any time after the date of this Lease, Landlord may substitute for
the Leased Premises, other premises in the Building (the "New Leased
Premises"), in which event the New Leased Premises shall be deemed to be the

located. If Tenant is then occupying the Leased Premises, Landlord shall pay
the actual reasonable expenses of physically moving Tenant, its property and
equipment to the New Leased Premises; Landlord shall give Tenant not less than
thirty (30) days prior written notice of such substitution; and Landlord, at
its expense, shall improve the New Leased Premises with improvements
substantially similar to those in the Leased Premises at the time of such
substitution. Tenant shall cooperate fully with Landlord in relocating to the
New Leased Premises.

22.    REAL ESTATE BROKERS: INDEMNIFICATION

       Tenant represents that, except for Klaff Realty, LP and the firm, if
any, identified in
<PAGE>

                                                                         PAGE 34

subsection 1.01.K, Tenant has not dealt with any real estate broker, sales
person, or finder in connection with this Lease, and no such person initiated
or participated in the negotiation of this Lease, or showed the Leased Premises
to Tenant. Tenant hereby agrees to indemnify and hold harmless Landlord from
and against any and all liabilities and claims for commissions and fees arising
out of a breach of the foregoing representation. Landlord shall be responsible
for the payment of all commissions to the broker, if any, specified in this
Section 22, based upon the leasing commission policy of Landlord applicable to
the Building and in effect as of the date of this Lease.


23.   SUBORDINATION AND ATTORNMENT

23.01 Subordination

      (A)  This Lease shall be subject and subordinate to the lien of any deed
      of trust or mortgage which Landlord may place upon the Leased Premises and
      Building, and to any renewals, extensions, modifications or replacements
      thereof provided, however, that if the Lease is in full force and effect
      and there are no Defaults thereunder on the part of the Tenant the right
      of possession of Tenant to the Leased Premises and Tenant's rights arising
      out of this Lease shall not be affected or disturbed by any mortgagee, or
      any party claiming title through such a mortgagee or deed of trust in the
      exercise of any of its rights under a holder of a deed of trust or
      mortgage or any note secured thereby, subject to the following, Landlord
      agrees to provide Tenant with a Non-Disturbance Agreements reasonably
      acceptable to such mortgagee or deed of trust holder and Tenant, covering
      any existing lenders or underlying fee owners. Tenant agrees to
      subordinate its leasehold estate to future mortgages or encumbrances only
      on the condition that the instruments creating such mortgages or
      encumbrances contain an apt provision recognizing the existence of this
      Lease and agreeing that so long as no Default shall be continuing under
      this Lease, this Lease shall not be terminated or otherwise affected in
      the event of a foreclosure, sale or default under such mortgages or
      encumbrances. In the event that a mortgagee, or any other person, acquires
      title to the Leased Premises pursuant to the exercise of any remedy
      provided for in the deed of trust or mortgage, this Lease shall not be
      terminated or affected by said foreclosure or sale, or any such
      proceeding, and said mortgagee shall agree that any sale of the premises
      pursuant to the exercise of any rights and remedies under the deed of
      trust or mortgage, or otherwise, shall be made subject to this Lease, and
      the rights of the Tenant hereunder, provided that Tenant shall attorn to
      said mortgagee or such person as its new landlord. Tenant shall sign such
      agreements evidencing said subordination as Landlord may reasonably
      request, if such form is reasonably acceptable to Tenant in accordance
      with the above criteria.

      (B)  Tenant shall at anytime and from time to time within fifteen (15)
      days after written request from Landlord execute and deliver to the
      Landlord or any prospective Landlord or mortgagee or prospective mortgagee
      a sworn and acknowledged estoppel certificate, settingforth such items as
      indicated in Article 20, supra ("Estoppel Certificate"). It is intended
      that any such statement delivered pursuant to this subsection may be
      relied upon by any prospective purchases or mortgagee and their respective
      successors and assigns and Tenant shall be liable for all loss, cost or
      expense resulting from the failure of any sale or funding of any loan
      caused by any misstatement contained in such estoppel certificate only to
      the extent such statements pertain to this Lease. To the extent Tenant is
      required under

<PAGE>


                                                                         PAGE 35



       this Lease to provide Landlord with an estoppel certificate, Landlord
       shall also be required to provide Tenant with an estoppel certificate
       upon Tenant's reasonable request. In either event, the party requesting
       the estoppel certificate shall also join in the execution of the
       document.

23.02  Attornment
       In the event of the cancellation or termination of any ground lease,
accordance with its terms or by the surrender thereof, whether voluntary,
involuntary or by operation of law, or by summary proceedings, or the
foreclosure of any such Mortgage by voluntary agreement or otherwise, or the
commencement of any judicial action seeking such foreclosure, or deed in lieu of
foreclosure, Tenant, at the request of the then Landlord, shall attorn to and
recognize such ground lessor, mortgagee or purchaser in foreclosure as Tenant's
Landlord under this Lease. Tenant agrees to execute and deliver at any time upon
request of such ground lessor, mortgagee, purchaser, or their successors, any
instrument to further evidence such attornment. This Lease may be terminated by
the mortgagee or ground lessor if Tenant is named as a party, by other than the
mortgagee or ground lessor, and served with process in any applicable proceeding
and a warrant or judgment for possession of the Premises is issued in such
proceeding or a foreclosure sale is held. However, if Tenant is not named as a
party in such proceedings, then Tenant hereby waives its right, if any, to elect
to terminate this Lease or to surrender possession of the Premises in the event
of any such ground lease termination or mortgage foreclosure.

23.03  Attorney-in-fact
       As and for additional security for the performance of its duties
hereunder and to induce Landlord to enter into this Lease, the Tenant shall
execute promptly such instruments or certificates to carry out the intent of
Section 20 and Sections 23.01 and 23.02 above as shall be requested by the
Landlord, or any mortgagee. If within fifteen (15) days after the date of a
written request by Landlord, or any mortgagee to execute such instruments, the
Tenant shall not have executed the same, the Landlord may, at its option,
execute same on behalf of Tenant without incurring any liability on account
thereof.

23.04  Mortgagee Protection
       Tenant agrees to give any mortgagees and/or trust deed holders, by
registered or certified mail, a copy of any notice of default served upon the
Landlord by Tenant, provided that prior to such notice Tenant has received
notice (by way of service on Tenant of a copy of an assignment of rents and
leases, or otherwise) of the address of such mortgagees and/or trust deed
holders. Tenant further agrees that if Landlord shall have failed to cure such
default within the time provided for in this Lease, then the mortgagees and/or
trust deed holders shall have an additional thirty days after receipt of notice
thereof within which to cure such default or if such default cannot be cured
within that time, then such additional notice time as may be necessary, if,
within such thirty days, any mortgagee and/or trust deed holder has commenced
and is diligently pursuing the remedies necessary to cure such default
(including but not limited to commencement of foreclosure proceedings, if
necessary to effect such cure). Such period of time shall be extended by any
period within which such mortgagee and/or trust deed holder is prevented from
commencing or pursuing such foreclosure proceedings by reason of Landlord's
bankruptcy. Until the time allowed as aforesaid for mortgagee and/or trust deed
holder to cure such defaults has expired without cure, Tenant shall have no
right to, and shall not, terminate this Lease on account of default. This Lease

                                                                         PAGE 36

may not be modified or amended so as to reduce the Rent or shorten the term, or
so as to adversely affect in any other respect to any material extent the
rights of the Landlord, nor shall this Lease be canceled or surrendered,
without the prior written consent, in each instance, of the ground lessor or
the mortgagee.

24.       NOTICES
          All notices required or permitted to be given hereunder shall be in
writing and shall be deemed given and delivered, whether or not received, when
deposited (A) with a reputable commercial courier, by overnight delivery or (B)
in the United States Mail, certified mail, return receipt requested, under
either method, properly addressed and all charges and/or postage paid, at the
following addresses: (Y) To Landlord at the address set forth in Section
1.01.B, or such other address as Landlord shall designate by written notice to
Tenant, and; (Z) To Tenant at the address specified in 1.01.C. prior to the
Commencement Date, and at the Leased Premises after the Commencement Date, or
such other address as Tenant shall designate by written notice to Landlord.

25.       MISCELLANEOUS
25.01     Late Fee and Interest Charge
          All Rent as defined in Section 3 (unless otherwise provided herein)
owed by the Tenant to the Landlord hereunder shall be paid in a timely manner.
In the event that the Tenant fails to so remit Rent when due:

          (A)  Late Fee.
               A late fee will accrue for all Base Monthly Rent or monthly
Additional Rent if not remitted within ten (10) days of the date due pursuant
to section 3.01. A late fee will accrue if Rent, other than Base Monthly Rent
or monthly Additional Rent (e.g. Landlord's additional or after-hours services)
is not remitted within ten (10) days of the date due, as for Rent, and from the
date the Landlord renders written statements of account therefor, as for
Additional Rent items. Said late fee shall be to help defray the additional cost
to Landlord for processing such late payments and other administrative expenses
caused by the tardy payment.

          (B)  Interest Charge.
               An interest charge will accrue for all Base Monthly Rent or
monthly Additional Rent if not remitted within five (5) days of the date due
pursuant to section 3.01. An interest charge fee will accrue if Rent, other
than Base Monthly Rent or monthly Additional Rent (e.g. Landlord's additional
or after-hours services) is not remitted within five (5) days from the date
due, as for Rent, and the Landlord renders written statements of account
therefor, as for Additional Rent items. Said interest charge shall compensate
Landlord for the time value of monies outstanding.

The afore-mentioned late fee and/or interest charge shall be determined from
the date payment was originally due until the date paid, calculated at the rate
of three percent (3%) per annum above the prime rate of interest in effect at
the First National Bank of Chicago as same may change from time to time, or at
the maximum legal rate of interest allowed by law, if such maximum legal rate is
<PAGE>
                                                                         PAGE 37


applicable and lower.

       Such late fee and/or interest charge shall accrue without demand for
payment by Landlord and shall be payable upon written demand, and shall be
Additional Rent hereunder. The failure of Tenant to pay such within twenty (20)
days after written notice of demand shall be an additional event of default
hereunder. The provision for such late fee and interest charge shall be in
addition to all of Landlord's other rights and remedies provided hereunder and
at law and shall not be construed as liquidated damages or a limiting Landlord's
remedies in any manner.

25.02  Entire Agreement

       This lease, the Exhibits attached hereto and the Workletter, if
applicable, contain the entire agreement between Landlord and Tenant concerning
the Leased Premises and there are no other agreements, either oral or written.

25.03  No option

       The execution of this Lease by Tenant and delivery of same to Landlord or
the Manager does not constitute a reservation of or option for the Leased
Premises or an agreement to enter into a Lease. This Lease shall become
effective only if and when Landlord executes and delivers same to Tenant;
provided, however, the execution and delivery by Tenant of this Lease to
Landlord or the Manager shall constitute an irrevocable offer by Tenant to lease
the Leased Premises on the terms and conditions herein contained, which offer
may not be withdrawn or revoked for thirty days after such execution and
delivery.

25.04  Accord and Satisfaction

       No payment by Tenant or receipt by Landlord of a lesser amount than any
installment or payment of Rent due shall be deemed to be other than on account
of the amount due, and no endorsement or statement on any check or any letter
accompanying any or payment of Rent shall 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 installment or payment of Rent or pursue
any other remedies available to Landlord. No receipt of money by Landlord from
Tenant after the termination of this Lease of Tenant's right of possession of
the Leased Premises shall reinstate, continue or extend the Term.

25.05  Landlord's Obligations on Sale of Building

       In any event of any sale or other transfer of the Building, Landlord and
the seller or transferor (and the beneficiaries of any selling or transferring
land trust) shall be entirely freed and relieved of all agreements and
obligations of Landlord hereunder accruing or to be performed after the date of
such sale or transfer, provided said transferee assumes Landlord's obligations
hereunder.

25.06  Binding Effect

       This Lease shall be binding upon and inure to the benefit of Landlord and
Tenant and their respective heirs, legal representatives, successors and
permitted assigns.

25.07  Modification of Lease

       Should any mortgagee, leasehold or otherwise, require a modification or
modifications of this Lease, which modification or modifications will not bring
about any increased cost or expense to Tenant or in any other way substantially
change the rights and obligations of Tenant hereunder, then

                                                                         PAGE 38


and in such event, Tenant agrees that this Lease may be so modified.

convenience and in no way define, limit, construe, or describe the scope or
intent of such Sections.

25.09  Applicable Law
       This Lease shall be construed in accordance with the laws of the State of
Illinois. If any term, covenant or condition of this Lease or the application
thereof to any person or circumstance shall, to any extent, be invalid or
unenforceable, the remainder of this Lease, or the application of such term,
covenant or condition to persons or circumstances other than those as to which
it is held invalid or unenforceable, shall not be affected thereby and each
item, covenant or condition of this Lease shall be valid and be enforced to the
fullest extent permitted by law.

obligations hereunder.

       If Tenant fails timely to perform any of its duties under this Lease or
the Workletter, Landlord shall have the right, but not the obligation, after the
expiration of any grace period elsewhere under this Lease or the Workletter
expressly granted to Tenant for the performance of such duty, to perform such
duty on behalf, and at the expense of Tenant, without further prior notice to
Tenant, and all sums expended or expenses incurred by Landlord in performing
such duty shall be deemed to be additional Rent under this Lease and shall be
due and payable upon demand by Landlord.

be deemed to be a part hereof and hereby incorporated herein.

25.13  Beneficiary
       The term "Beneficiary" or "Beneficiaries", as used in this Lease, means
the individual or legal entity which from time to time is the beneficial owner
of title to the Real Property. Any liability or obligation of Landlord, where

limited to the fee simple estate which Landlord owns in the Leased Premises,
Building, and underlying real property. The parties hereby covenant and
acknowledge that neither the Beneficiary, its general and limited partners,
including any of the Indemnitees as heretofore defined in Section 10.01, nor
their respective officers, employees, and agents shall be individually or
personally liable for any claims arising out of this Lease beyond their
respective interests in the Property. A deficit capital account of any such
partner shall not be deemed an asset or property of said partnership.

25.14  Land Trustee Exculpation
       It is expressly understood and agreed that nothing in this Lease
contained shall be construed as creating any liability whatsoever against any
land trustee which may, from time to time, hold legal title to the Building and
underlying real property, or any successor thereof or thereto, without
<PAGE>
                                                                         PAGE 39

limiting the generality of the foregoing, there shall be no personal liability
to pay any indebtedness accruing hereunder or to perform any covenant, either
express or implied, herein contained, or to keep, preserve or sequester any
property of said Trust, and that all personal liability of said Trustee of
every sort, if any, is hereby expressly waived by Tenant, and by every person
now or hereafter claiming any right or security hereunder, and that so far as
the parties hereto are concerned, the owner of any indebtedness or liability
accruing hereunder shall look solely to the Trust Estate from time to time
subject to the provisions of a trust agreement for the payment thereof. It is
further understood and agreed that the said Trustee has no agents or employees
and merely holds naked legal title to the property herein described; that said
Trustee has no control over, and under this Lease, assumes no responsibility
for (1) the management or control of such property, (2) the upkeep, inspection,
maintenance or repair of such property, (3) the collection of rents or the
rental of such property, or (4) the conduct of any business which is carried on
upon such property.

          Tenant represents and warrants that it is duly formed and in good
standing, and has full corporate or partnership power and authority, as the
case may be, to enter into this Lease and has taken all corporate or

contemplated herein, so that when executed, this Lease constitutes a valid and
binding obligation enforceable in accordance with its terms. Tenant shall
provide Landlord with corporate resolutions or other proof in a form acceptable
to Landlord, authorizing the execution of the Lease at the time of such
execution.

25.16     No Presumption Against Drafter

          interpretation, validity or enforceability of this Lease or any of its
          terms or conditions, there shall be no inference, presumption, or
          conclusion drawn whatsoever against either party by virtue of that
          party having drafted the Lease or any portion thereof.

25.17     Attorney's Fees and Costs
