     This Office Space Lease, which includes the preceding Summary of Basic
Lease Provisions and Exhibits (the "Summary") and exhibits attached hereto and
incorporated herein by this reference (the Office Space Lease and Summary to be
known sometimes collectively hereafter as the "Lease"), dated as of the date set
forth in Section 1.1.14 of the Summary, is made by and between Landlord and
Tenant.

1.   LEASE OF PREMISES
     -----------------

     1.1  Premises and Building.  Landlord hereby leases to Tenant, and Tenant
          ---------------------
hereby leases from Landlord the premises set forth in Section 1.1.5 of the
Summary ("Premises") which Premises are located in the building whose address is
303 West Madison, Chicago, Illinois (which building, together with the parking
garage therein and all equipment, fixtures, and machinery which may now or
hereafter exist therein or thereon are collectively referred to herein as the
"Building"), for the Lease Term and upon the terms, covenants and conditions set
forth in this Lease.  This Lease shall be in full force and effect from the date
it is signed by Landlord and Tenant.

          With respect to any or all exterior balconies, patios, terraces or
similar areas which may be appurtenant to the Premises, such areas shall not be
used by Tenant, its employees, invitees, guests, agents or contractors for any
purpose whatsoever and Tenant shall indemnify, defend, protect and hold harmless
Landlord, its beneficiaries and their respective employees, officers, directors,
agents, contractors, successors and assigns from and against all claims,
damages, losses, liabilities and causes of action whatsoever arising out of
Tenant's breach of the foregoing prohibition.

     1.2  Property.  The term "Property" as used in this Lease, shall mean (a)
          --------
the Building, (b) the land upon which the Building is located and all other
improvements now or hereafter located upon said land, and all appurtenances
thereto, and (c) at Landlord's discretion, any additional real property, areas,
buildings or other improvements added thereto.  Landlord reserves the right to
make alterations or additions to or to change the elements of the Property;
provided that exercise of any such rights shall not unreasonably interfere with
Tenant's use of the Premises.  Tenant acknowledges that Landlord has made no
representation or warranty regarding the condition of the Property except as
specifically set forth in this Lease.

                                       1


2.   LEASE TERM
     ----------

     The term of this Lease ("Lease Term") shall commence on the date set forth
in Section 1.1.7 of the Summary (the "Commencement Date"), (subject, however, to
the terms of Section 5 of the Work Letter attached hereto as Exhibit 2), and
expire on the date set forth in Section 1.1.8 of the Summary (the "Expiration
Date") unless sooner terminated as provided in this Lease.  If Landlord shall be
unable to deliver possession of the Premises to Tenant on or before the
anticipated Commencement Date set forth in Section 1.1.7 of the Summary for any
reason whatsoever (including holding over by an existing tenant or occupant of
the Premises), Landlord shall not be subject to any liability for the failure to
do so nor shall such failure affect the validity of this Lease or the
obligations of Tenant hereunder.  Following the Commencement Date, Landlord
shall deliver to Tenant the Confirmation of Lease Term Dates attached hereto as
Exhibit 5, which Confirmation of Lease Term Dates Tenant shall execute and
- ---------
return to Landlord within five (5) days after receipt thereof.

     In the event the Commencement Date shall not have occurred on or before
June 1, 2000, Tenant shall have the right to terminate this Lease by giving
written notice of termination ("Termination Notice") to Landlord on or before
June 10, 2000. In the event Tenant exercises the termination right in the
preceding sentence, this Lease shall terminate unless the Commencement Date
shall have occurred on or before July 1, 2000 in which event the Termination
Notice shall be deemed null and void. In the event this Lease shall terminate,
Landlord shall return the Security Deposit or the Letter of Credit (as
hereinafter defined) delivered by Tenant to Landlord and Monthly Base Rent for
the first full calendar month of the Lease Term paid pursuant to Paragraph 3
below, whereupon neither party shall have any further rights, obligations or
liabilities under this Lease, except for any obligations or liabilities that
expressly survive termination.

3.   BASE RENT
     ---------

     Tenant shall pay to Landlord in the manner and at the place set forth in
Section 4.3 of this Lease, the monthly Base Rent ("Monthly Base Rent") specified
in Section 1.1.9 of the Summary monthly, in advance, on the first day of each
calendar month during the Lease Term, except that Monthly Base Rent for the
first full calendar month of the Lease Term shall be paid concurrently with the
execution of this Lease by Tenant.  If the Lease Term commences on a day other
than the first day of a calendar month or terminates on a day other than the
last day of a calendar month, then Monthly Base Rent for such month will be
prorated on a per diem basis based on the number of days in such month and the
excess of the installment of Monthly Base Rent paid concurrently with the
execution of this Lease by Tenant over such prorated amount for the first
calendar month of the Lease Term shall be applied against Monthly Base Rent for
the first full calendar month of the Lease Term.

          violations by Landlord (as opposed to violations by any tenant and/or
          the Tenant) of

                                       5


          any governmental rule or authority, this Lease or any other lease in
          the Property, or due to Landlord's negligence or willful misconduct.

                    (xxii)    Costs for sculptures, paintings, or other objects
          of art (nor insurance thereon or extraordinary security in connection
          therewith).

                    (xxiii)   Wages, salaries, or other compensation paid to any
          executive employees above the grade of building manager.

                    (xiv)     The cost of correcting any building code or other
          violations which existed prior to the Commencement Date.

                    (xv)      The cost of containing, removing or otherwise
          remediating any contamination of the Property (including the
          underlying land and ground water) where such contamination was not
          caused by Tenant.

                    (xvi)     The cost of capital investment items except as
          provided in subdivision (viii) of the items included in Operating
          Expenses.


          If at any time the Building is less than 95% occupied or Landlord is
     not supplying services to at least 95% of the rentable areas of the
     Building during an entire calendar year, then Landlord may adjust actual
     Operating Expenses to Landlord's estimate of that amount which would have
     been paid or incurred by Landlord as Operating Expenses had the Building
     been 95% occupied or serviced, and the Operating Expenses as so adjusted
     shall be deemed to be the actual Operating Expenses for such calendar year.
     If Landlord does not furnish during any Expense Year any particular work or
     service (the cost of which, if performed by Landlord, would constitute an
     Operating Expense) to a tenant which has been authorized by Landlord to
     perform such work or service in lieu of the performance thereof by
     Landlord, then Operating Expenses shall be deemed to be increased by an
     amount equal to the additional expense which would reasonably have been
     incurred during such Expense Year by Landlord if it had, at its cost,
     furnished such work or service to such tenant.

          (e)  "Taxes" shall mean and include all federal, state and local
     government taxes, assessments and charges of any kind or nature, now or
     hereafter imposed, whether general, special, ordinary or extraordinary, and
     any increases resulting from the reassessments caused by any change in
     ownership of the Property, incurred by Landlord or assessed against the
     Property, in a calendar year with respect to the value, ownership, use,
     occupation, management, operation, maintenance, vehicle parking, repair or
     leasing of the Property.  If any special assessment payable in installments
     is levied against all or any part of the Property, then, at Landlord's
     discretion, Taxes for the calendar year in which such assessment is levied
     and for

                                       6


     each calendar year thereafter shall include only the amount of any
     installments of such assessment plus interest thereon paid or payable
     during such calendar year (without regard to any right to pay, or payment
     of, such assessment in a single payment).  Taxes shall include, without
     limitation, real estate and transit district taxes and assessments, sewer
     charges, sales and use taxes (unless included in Operating Expenses), ad
     valorem taxes, personal property taxes, and all taxes, assessments and
     charges in lieu of, substituted for or in addition to any or all of the
     foregoing taxes, assessments and charges.  Taxes shall also include the
     amount of all fees, costs and expenses (including, without limitation,
     attorneys' fees and court costs) paid or incurred by Landlord during such
     calendar year in seeking or obtaining any refund or reduction of Taxes or
     for contesting or protesting any imposition of Taxes, whether or not
     successful and whether or not attributable to Taxes assessed, paid or
     incurred in such calendar year.  Notwithstanding any provision of this
     Section 4.1(e) to the contrary, Taxes shall not include any federal, state
     or local government income, franchise, capital stock, transfer, inheritance
     or estate taxes, except to the extent such taxes are in lieu of or a
     substitute for any of the taxes, assessments and charges previously
     described in this Section 4.1(e).

     4.2  Allocation of Direct Expenses.  Direct Expenses are determined
          -----------------------------
annually for the Property as a whole.  The portion of Direct Expenses allocated
to the tenants of the Building shall consist of:  (a) all Direct Expenses
attributable solely to the Building and the land parcel(s) upon which the
Building is located to the extent the same are separately identifiable and
capable of separate assessment, as reasonably determined by Landlord; and (b) an
equitable portion of the Direct Expenses attributable to the Property as a whole
and not attributable solely to, and/or not separately identifiable for, the
Building.

     4.3  Payment of Rent.  Tenant shall pay to Landlord's Management Agent, as
          ---------------
custodian on behalf of Landlord, at the address specified in Section 1.1.2 of
the Summary, or to such other person or entity or at such other place as
Landlord may from time to time direct in writing, all amounts due Landlord from
Tenant under this Lease, including, without limitation, Monthly Base Rent and
the Estimated Direct Expenses and payments of Direct Expenses pursuant to
Sections 4.5 and 4.6 below (such Estimated Direct Expenses and Direct Expense
payments and all other amounts payable by Tenant, other than the Monthly Base
Rent, shall hereinafter be referred to collectively as "Additional Rent"; the
Monthly Base Rent and Additional Rent are hereinafter referred to collectively
as the "Rent").  Except as specifically provided in this Lease, Rent shall be
paid without abatement, deduction or setoff of any kind, it being the intention
of the parties that, to the full extent permitted by law, Tenant's covenant to
pay Rent shall be independent of all other covenants contained in this Lease.
All of Tenant's theretofore accrued obligations hereunder to pay Rent shall
survive the termination of this Lease.

     4.4  Calculation and Payment of Tenant's Share of the Direct Expenses.
          ----------------------------------------------------------------
Tenant shall pay to Landlord, in the manner set forth in Sections 4.5 and 4.6
below, and as

                                       7


Additional Rent, an amount equal to Tenant's Share of the Direct Expenses for
each Expense Year any portion of which falls within the Lease Term.

     4.5  Statement of Actual Direct Expenses and Payment by Tenant.  Landlord
          ---------------------------------------------------------
shall endeavor to give to Tenant on or before the first day of April following
the end of each Expense Year, a statement (the "Statement") which shall state
the Direct Expenses incurred or accrued for such preceding Expense Year, and
which shall indicate the amount of Tenant's Share thereof and payment of
Tenant's Estimated Direct Expenses.  Upon receipt of the Statement for each
Expense Year ending during the Lease Term, if the amount of Tenant's Share of
Direct Expenses exceeds Tenant's payment of Tenant's Estimated Direct Expenses
for such Expense Year, then Tenant shall pay, with its next installment of
Monthly Base Rent due, the full amount of such excess (the "Excess") for such
Expense Year.  If Tenant's payment of Tenant's Estimated Direct Expenses exceeds
the amount of Tenant's share of Direct Expenses for such Expense Year as shown
on the Statement, then the amount of such excess shall be credited against
Tenant's Estimated Direct Expenses next due under this Lease, or if the Lease
Term has expired and no further amounts are due from Tenant under this Lease,
Landlord shall refund to Tenant the amount of any unapplied excess not later
than 30 days following delivery of the Statement.  The failure of Landlord to
timely furnish the Statement for any Expense Year shall not be deemed a default
by Landlord nor shall it prejudice Landlord from enforcing its rights under this
Section 4.

     Even though the Lease Term has expired and Tenant has vacated the Premises,
when the final determination is made of Tenant's Share of the Direct Expenses
for the Expense Year in which this Lease terminates, if an Excess is present,
Tenant shall immediately pay to Landlord an amount as calculated pursuant to the
provisions of Section 4.4 of this Lease.  The provisions of this Section 4.5
shall survive the expiration or earlier termination of the Lease Term.

     4.6  Statement of Estimated Expenses.  In addition, Landlord shall endeavor
          -------------------------------
to give Tenant a yearly expense estimate statement (the "Estimate Statement")
which shall set forth Landlord's reasonable estimate ("the Estimate") of what
Tenant's Share of the total amount of the Direct Expenses allocated to tenants
of the Building pursuant to the terms of Section 4.2 above for the then-current
Expense Year shall be (the "Estimated Direct Expenses").  Such Estimate may be
revised by Landlord whenever it obtains information relevant to making such
Estimate more accurate.  The failure of Landlord to timely furnish the Estimate
Statement for any Expense Year shall not be deemed a default by Landlord nor
shall it preclude Landlord from enforcing its rights to collect any Estimated
Direct Expenses under this Section 4.  Tenant shall pay to Landlord, at the time
and place and in the manner that payments of Monthly Base Rent are due
hereunder, one-twelfth of the Estimate of Tenant's Share of Direct Expenses.  In
addition, if pursuant to the Estimate Statement an estimated Excess is
calculated for the then current Expense Year, Tenant shall pay, with its next
installment of the Monthly Base Rent due, the amount of such estimated Excess
for the then-current Expense Year.  Until a new Estimate Statement is

                                       8


furnished, Tenant shall pay monthly, with the Monthly Base Rent installments, an
amount equal to 1/12th of the total Estimated Direct Expenses set forth in the
previous Estimate Statement delivered by Landlord to Tenant.

     4.7  Tenant's Right to Inspect Books and Records.  On reasonable advance
          -------------------------------------------
notice, Landlord shall make available to Tenant's licensed, certified public
accountant, at Tenant's cost, during the 45 days following the receipt by Tenant
of the Statement of Direct Expenses with respect to the Expense Year applicable
to such Statement, Landlord's books and records where the same are maintained
with respect to the Direct Expenses for such Expense Year.  Landlord shall have
no obligation to allow its books and records to be reviewed by any person other
than Tenant's licensed, certified public accountant.  If Tenant wishes to
contest any item of Direct Expenses within a particular Statement, Tenant shall
do so in a written notice received by Landlord within 30 days following Tenant's
receipt of such Statement, which notice shall specify in detail the item or
items being contested and the specific grounds therefor.  However, the giving of
notice shall not relieve Tenant from the obligation to pay any amounts
(including amounts contested by Tenant) in such Statement in accordance with
Sections 4.5 or 4.6 above.  If Tenant timely gives said notice to Landlord, any
dispute with respect to any item or items in such Statement, including any
calculations therein, shall be submitted to Landlord's firm of certified public
accountants ("CPA"), whose decision (the "CPA Decision") shall be submitted to
and binding on the parties.  If the CPA Decision reveals that Landlord has over-
charged Tenant, then within 30 days after the results of the CPA Decision are
made available to Landlord, Landlord shall credit against future Additional Rent
the amount of such over-charge.  If the CPA Decision reveals that the Tenant was
undercharged, then within 30 days after the results of such CPA Decision are
made available to Tenant, Tenant shall reimburse to Landlord the amount of such
undercharge.  Tenant shall pay on demand all fees of the CPA with respect to any
such dispute, unless the amount of the Tenant's Share of Direct Expenses, as
provided in such Statement, exceeds the amount of Tenant's Share of Direct
Expenses as finally determined by the CPA by more than 10%.  In addition, if the
CPA Decision indicates that the Statement exceeded the actual Direct Expenses
which should have been charged to Tenant by more than 10%, the reasonable cost
of Tenant's audit shall be paid by Landlord.  Notwithstanding anything else in
this Section 4.7 to the contrary, if Tenant fails to give such notice within
said 45 day period or fails to pay all amounts (including amounts contested by
Tenant) in such Statement, in accordance with Section 4.5 or this Section 4.7,
whether or not contested, Tenant shall have no further right to contest any item
or items in such Statement and Tenant shall be deemed to have accepted such
Statement.

     4.8  Taxes and Other Charges for Which Tenant Is Directly Responsible.
          ----------------------------------------------------------------
Subject to Section 30.9 of this Lease, Tenant shall reimburse Landlord upon
demand for any and all taxes or assessments required to be paid by Landlord
(except to the extent included in Taxes by Landlord), excluding state, local and
federal personal or corporate income taxes measured by the net income of
Landlord from all sources and estate and inheritance taxes, whether or not now
customary or within the contemplation of the parties hereto, when:

                                       9


          (a)       Said taxes are measured by or reasonably attributable to
     the cost or value of Tenant's equipment, furniture, fixtures and other
     personal property located in the Premises, or by the cost or value of any
     leasehold improvements made in or to the Premises by or for Tenant, to the
     extent the cost or value of such leasehold improvements exceeds the cost or
     value of a building standard build-out as determined by Landlord regardless
     of whether title to such improvements shall be vested in Tenant or
     Landlord;

          (b)       Said taxes are assessed upon or with respect to the
     possession, leasing, operation, management, maintenance, alteration,
     repair, use or occupancy by Tenant of the Premises or any portion of the
     Building or Property;

          (c)       Said taxes are assessed upon this transaction or any
     document to which Tenant is a party creating or transferring an interest or
     an estate in the Premises; or

          (d)       Said assessments are levied or assessed upon the Property or
     any part thereof or upon Landlord and/or by any governmental authority or
     entity, and relate to the construction, operation, management, use,
     alteration or repair of mass transit improvements (collectively, "Mass
     Transit Assessments").

5.   SECURITY DEPOSIT
     ----------------

     Concurrently with the execution and delivery of this Lease, Tenant shall
provide Landlord with a security deposit in the amount set forth in Section
1.1.12 of the Summary as security for the full and punctual performance by
Tenant of all of the terms and provisions of this Lease.  At Tenant's option,
the security deposit may be either cash or a letter of credit ("Letter of
Credit").  For purposes of this Section 5, if Tenant shall have elected to
deposit cash, all references herein to proceeds of the Letter of Credit shall be
deemed to refer to the cash security deposit.  In the event Tenant defaults in
the performance of any of the terms of this Lease (including, without
limitation, the payment of Monthly Base Rent and/or Additional Rent) and such
default is not cured before the expiration of any applicable notice and cure
period, Landlord may draw upon the Letter of Credit, and apply all or any part
of the proceeds of the Letter of Credit to the extent required for the payment
of any Monthly Base Rent or Additional Rent or for any sum for which Tenant is
liable to Landlord under any of the terms of this Lease, including any payments,
damages or deficiency which Landlord is then entitled to collect from Tenant
under this Lease, whether accruing before or after summary proceedings or other
re-entry by Landlord.  In the case of every such use or application of the
proceeds of the Letter of Credit, Tenant shall, on demand, either pay to the
Landlord the sum so used or applied (or deliver a second letter of credit
identical in form and substance to the original letter of credit and issued by
an Acceptable Bank (as hereinafter defined) in such amount to Landlord) which
sum shall be added to the security held hereunder so that the same shall be

                                       10


replenished to its former amount. In the event of an assignment by Landlord of
its interest in this Lease, Landlord shall transfer the Letter of Credit or the
cash security deposit, as the case may be, to the assignee and Landlord shall so
notify Tenant in writing of any such transfer. Upon such transfer of the Letter
of Credit or the cash security deposit, as the case may be, Landlord shall ipso
facto be released by Tenant from all liability for the return of such Letter of
Credit or cash security deposit and in such case, Tenant agrees to look solely
to the new Landlord for the return of such Letter of Credit or cash security
deposit. The provisions of the preceding sentence shall apply to every transfer
or assignment made of the Letter of Credit or the cash security deposit to a new
Landlord. Tenant shall not assign or encumber or attempt to assign or encumber
the Letter of Credit or the cash security deposited herein as security and
neither Landlord nor its successors or assigns shall be bound by any such
assignment, encumbrance or attempted assignment or encumbrance. In the event the
Letter of Credit is to expire by its terms prior to the expiration date of this
Lease (including, without limitation, a notice from the bank that issued the
Letter of Credit that it is not automatically renewing the expiration date for
an additional one (1) year period) and Landlord shall not have received at least
thirty (30) days prior to the expiration date of the Letter of Credit a
substitute Letter of Credit issued by an Acceptable Bank (as hereinafter
defined) which is substantially identical to the original Letter of Credit
except for a later expiration date at least sixty (60) days beyond the then
current expiration date, Landlord may draw upon the entire proceeds of the
Letter of Credit. In the event the Landlord draws upon the Letter of Credit as
aforesaid, the proceeds of such drawing shall be held by the Landlord in
accordance with the terms of this Section 5, as if such proceeds constituted the
Letter of Credit.

     If Tenant elects to deposit a Letter of Credit as the security deposit,
such Letter of Credit shall be a clean, irrevocable standby Letter of Credit in
the form of Exhibit 4 attached hereto, shall be issued by a federally chartered
            ---------
commercial bank which is reasonably acceptable to Landlord ("Acceptable Bank"),
having an office in Chicago, Illinois, and shall have an expiration date which
is at least one (1) year after the date of issuance of the Letter of Credit.

     Provided Tenant is not in default under this Lease, the Security Deposit or
Letter of Credit, as the case may be, shall be reduced by Thirty-Three Thousand
Three Hundred Thirty-Three and 33/100 ($33,333.33) Dollars on each anniversary
of the Commencement Date.  If Tenant has deposited a Letter of Credit with
Landlord, then provided that Tenant is not in default under this Lease on the
anniversary of the Commencement Date, Landlord shall return to Tenant the Letter
of Credit then being held by Landlord upon receipt of a replacement Letter of
Credit issued by an Acceptable Bank and identical to the Letter of Credit then
being held by Landlord except that such replacement Letter of Credit shall be in
the reduced amount provided for herein.  If Landlord is holding a cash Security
Deposit, then provided Tenant is not in default under this Lease on the
anniversary of the Commencement Date, Landlord shall refund to Tenant the
amount, if any, by which the Security Deposit then being held by Landlord
exceeds the reduced amount provided for herein.

                                       11


     Neither the application of the proceeds of the Letter of Credit or of any
cash security deposit, as the case may be, set forth above nor the payment by
Tenant to restore such security deposit shall operate to cure such default or to
estop Landlord from pursuing any remedy to which Landlord would otherwise be
entitled.

     Within thirty (30) days following the expiration of the Lease Term or
earlier termination of this Lease, and provided there exists no default by
Tenant hereunder and no amounts are owing to Landlord by Tenant, the Security
Deposit or any balance thereof or the Letter of Credit, as the case may be,
shall be returned to Tenant (or, at Landlord's option, to Tenant's assignee).

6.   USE OF PREMISES
     ---------------

     6.1  Permitted Uses.  Tenant shall use and occupy the Premises solely for
          --------------
the Permitted Uses set forth in Section 1.1.11 of the Summary and for no other
use or purpose.

     6.2  Prohibited Uses.  Tenant shall not suffer or permit the Premises or
          ---------------
any part thereof to be used in any manner, or anything to be done therein, or
suffer or permit anything to be brought into or kept in the Premises which would
in any way (i) violate any law or requirement of public authorities, (ii) cause
structural injury to the Building or any part thereof, (iii) interfere with the
normal operation of the heating, air conditioning, ventilating, plumbing or
other mechanical or electrical systems of the Building or the elevators
installed therein, (iv) constitute a public or private nuisance or waste, (v)
alter the appearance of the exterior of the Building or any portion of the
interior thereof other than the Premises, (vi) impair or disturb the use for
normal office or retail purposes of any other area of the Building or Property
by, or occasion physical discomfort to, any of the other tenants or occupants of
the Building or Property or permit any vapors, fumes or odors to escape to, or
permeate into any other portion of the Building or Property or into the
ventilation system, (vii) permit excessive sound or offensive noise to be heard
outside of the Premises, or (viii) violate any of Tenant's other obligations
under this Lease.  Tenant shall not discharge or permit to be discharged any
materials into waste lines, vents or flues of the Building which might
reasonably be anticipated to cause damage thereto.  The water and wash closets
and other plumbing fixtures in or serving the Premises shall not be used for any
purpose other than those for which they shall have been designed or constructed
and no sanitary napkins, paper towels, sweepings, rubbish or rags shall be
deposited therein.  Tenant is expressly prohibited from using cooking stoves,
ovens (other than consumer-rated microwave ovens), space heaters and vending
machines.

     6.3  Removal of Equipment.  Tenant, at any time may remove its movable
          --------------------
trade fixtures and equipment from the Premises.  Tenant shall repair any damage
to the Premises caused by such removal, failing which Landlord may remove the
same and repair the Premises and Tenant shall pay the cost thereof to Landlord
on demand.

                                       12


     6.4  Reimbursement of Landlord.  Within ten days of written demand
          -------------------------
therefor, Tenant shall reimburse and compensate Landlord as Additional Rent for
all reasonable expenditures made by, or damages or fines sustained or incurred
by, Landlord due to non-performance or non-compliance with or breach or failure
to observe any term, covenant or condition of this Lease upon Tenant's part to
be kept, observed, performed or complied with.

     6.5  Compliance with Laws.  Prior to the commencement of the Lease Term, if
          --------------------
Tenant is then in possession, and at all times after commencement of the Lease
Term, Tenant, at Tenant's sole cost and expense, shall promptly comply with all
present and future laws, orders and regulations of all state, federal, municipal
and local governments, departments, commissions and boards and any direction of
any public officer pursuant to law, and all orders, rules and regulations of the
American Insurance Association (formerly the National Board of Fire
Underwriters), or any similar body which shall impose any obligation or duty
upon Landlord or Tenant with respect to the Premises, whether or not arising out
of Tenant's use or manner of use thereof (including Tenant's Permitted Uses),
or, with respect to the Building and/or Property if arising out of Tenant's use
or manner of use of the Premises, the Building and/or Property (including the
use permitted under this Lease); provided, however, that nothing herein shall
require Tenant to make structural repairs or alterations unless the same are
required due to Tenant's alterations (or alterations made on behalf of Tenant
and any alterations made at or prior to the Commencement Date other than the
Tenant Improvements, whether done by Landlord's contractor or by Tenant's
contractor) or Tenant has, by its specific manner of use of the Premises or
method of operation therein, violated any such laws, ordinances, orders, rules,
regulations or requirements with respect thereto or has otherwise given rise to
requirements under any such laws, ordinances, orders, rules, regulations or
requirements. If during the last six (6) months of the Lease Term Tenant would
have to spend in excess of Twenty-Five Thousand and No/100 ($25,000.00) Dollars
in capital improvements to comply with its obligations hereunder, Tenant shall
be responsible for a portion of the cost of such capital improvements ("Capital
Improvement Cost") equal to the Capital Improvement Cost multiplied times a
fraction, the numerator of which is the number of months remaining in the Lease
Term and the denominator of which is the useful life (in months) of the
applicable capital improvement(s) under the Internal Revenue Code; provided that
nothing herein shall be deemed to limit Tenant's obligation to make and pay the
entire cost of any such capital improvement(s) which result from Tenant's manner
of use of the Premises or method of operation therein or any alterations made by
Tenant or made on behalf of Tenant other than the Tenant Improvements.  Provided
Tenant does not occupy the Premises prior to the Commencement Date, nothing
herein shall obligate Tenant to comply with any laws requiring removal,
abatement or remediation of hazardous or toxic materials and/or asbestos located
in the Premises prior to the Commencement Date.  Tenant may, after securing
Landlord to Landlord's satisfaction against all damages, interest, penalties and
expenses, including, but not limited to, reasonable attorneys' fees, by cash
deposit or by surety bond in an amount and in a company satisfactory to
Landlord,

                                       13


contest and appeal any such laws, ordinances, orders, rules, regulations or
requirements provided same is done with all reasonable promptness and provided
such appeal shall not subject Landlord to prosecution for a criminal offense or
constitute a default under any lease or mortgage under which Landlord may be
obligated, or cause the Premises or any part thereof to be condemned or vacated,
and provided further that Tenant's right to contest and appeal laws relating to
such non-compliance shall have no adverse effect on the Building or Property
including, without limitation, on the ability to obtain (a) a building permit
for the Property, (b) a certificate of occupancy for the Property or any
portions thereof, or (c) a building completion sign-off for any work performed
in or on the Property.

     6.6  Tenant's Covenants.  Tenant shall comply with all applicable federal,
          ------------------
state and municipal laws, ordinances and regulations, and Building and Property
rules.  Nothing herein shall obligate Tenant to comply with any laws requiring
removal, abatement or remediation of hazardous or toxic materials and/or
asbestos located in the Premises prior to the Commencement Date.  Tenant shall
not directly or indirectly make any use of the Premises which may be prohibited
by any of the foregoing or which may be dangerous to persons or property or
which may increase the cost of insurance or require additional insurance
coverage.  Tenant agrees, at its sole expense, to comply with and conform to all
of the rules, regulations and requirements of any fire insurance rating
organization or similar organization and with all governmental authorities
having jurisdiction thereof, present or future, relating in any way to the
condition, use and occupancy of the Premises throughout the Lease Term,
including, without limitation, any applicable Illinois Inspection and Rating
Bureau, Fire Insurance Rating Organization and by the fire department having
jurisdiction over the Property; provided, however, that nothing herein shall
require Tenant to make structural repairs or alterations unless the same are
required due to Tenant's alterations (or alterations made on behalf of Tenant
and any alterations made at or prior to the Commencement Date other than the
Tenant Improvements, whether done by Landlord's contractor or by Tenant's
contractor) or Tenant has, by its specific manner of use of the Premises or
method of operation therein, violated any such laws, ordinances, orders, rules,
regulations or requirements with respect thereto or has otherwise given rise to
requirements under any such laws, ordinances, orders, rules, regulations or
requirements. If during the last six (6) months of the Lease Term Tenant would
have to spend in excess of Twenty-Five Thousand and No/100 ($25,000.00) Dollars
in capital improvements to comply with its obligations hereunder, Tenant shall
be responsible for a portion of the cost of such capital improvements ("Capital
Improvement Cost") equal to the Capital Improvement Cost multiplied times a
fraction, the numerator of which is the number of months remaining in the Lease
Term and the denominator of which is the useful life (in months) of the
applicable capital improvement(s) under the Internal Revenue Code; provided that
nothing herein shall be deemed to limit Tenant's obligation to make and pay the
entire cost of any such capital improvement(s) which result from Tenant's manner
of use of the Premises or method of operation therein or any alterations made by
Tenant or made on behalf of Tenant other than the Tenant Improvements.  Tenant
shall comply with and participate in any emergency and fire evacuation and
safety programs adopted by Landlord.  Tenant shall not permit inflammables such
as gasoline, kerosene, naphtha,

                                       14


benzene, or explosives or other intrinsically dangerous articles, goods or
merchandise to be brought into the Building. Tenant shall not use or allow
another person or entity to use any part of the Premises for storage, use,
treatment, manufacture or sale of any hazardous or toxic substance, material or
waste which is or becomes regulated by any local governmental authority, the
State of Illinois or the United States Government, except that nothing herein

reference, and such revised or additional rules and regulations reasonably
adopted by Landlord during the Lease Term and applied generally to all office
tenants of the Building (the "Rules and Regulations"). Tenant has reviewed the
Rules and Regulations and understands that Landlord shall have the right, but
not the obligation, to enforce the Rules and Regulations in order to preserve
the value and integrity of the Property. Any violation by Tenant or any of its
employees, agents, clients, customers, guests or invitees of any of the Rules
and Regulations so adopted by Landlord shall be a default by Tenant under this
Lease and may be restrained by court injunction; but whether or not so
restrained, Tenant acknowledges and agrees that it shall be and remain liable

enforce the Rules and Regulations or the terms, covenants and conditions of any
other lease against

                                       16


any other tenant or any other persons; Landlord shall not be liable to Tenant
for violation of the same by any other tenant, its employees, agents, guests,
invitees, licensees, customers, clients, family members, or by any other person;
and no such violation or failure of Landlord to enforce same shall constitute,
or be treated as contributing to, an eviction, actual or constructive, or affect
Tenant's covenants and obligations hereunder, or allow Tenant to reduce, abate
or offset the payment of any Rent or other sum due under this Lease. Landlord
shall not enforce any such Rule or Regulation against Tenant in a discriminatory
manner. Notwithstanding anything to the contrary contained in this Section, if
any rule or regulation is in conflict with any provision of this Lease, the
provisions of this Lease shall prevail. In addition, no such rule or regulation,
or any subsequent amendment thereto adopted by Landlord, shall in any way
materially adversely alter, reduce or affect any of Tenant's rights or
materially adversely enlarge any of Tenant's obligations under this Lease.

8.   SERVICES PROVIDED
     -----------------

     8.1  Standard Services.  Landlord shall furnish:
          -----------------

          (a)  Cooled or heated air as and when necessary for normal comfort as
     reasonably determined by Landlord under normal business operations and in
     the absence of the use of equipment or quantity of inhabitants which
     materially affects the temperature which would otherwise be maintained in
     the Premises, Monday through Friday from 8:00 am. to 6:00 p.m. and
     Saturdays from 8:00 am. to 1:00 p.m., Holidays (as defined below) excepted.
     If the use of heat generating equipment in the Premises materially affects
     the temperatures otherwise maintained by the air conditioning system for
     normal business operations, and thereby requires, in the reasonable
     judgment of Landlord, the modification of the air conditioning or
     ventilation systems of the Building or the air conditioning or ventilating
     equipment in the Premises or the installation of supplementary air
     conditioning units in the Premises, Landlord reserves the right to perform
     such modification or installation, and the cost thereof shall be paid by
     Tenant to Landlord at the time of completion of such modification or
     installation. Any increased expense in maintaining or operating the system
     resulting, in Landlord's reasonable opinion, from such modification shall
     be paid by Tenant. In addition, Tenant shall reimburse Landlord for all
     direct and indirect costs of installation and maintenance of any
     supplementary air conditioning equipment or units installed in accordance
     with this Section 8.1(a). Tenant agrees to keep and cause to be kept closed
     all windows in the Premises and at all times to cooperate fully with
     Landlord in the operation of said system and to abide by all reasonable
     regulations and requirements which Landlord may prescribe to permit the
     proper functioning and protection of the heating, ventilation and air
     conditioning systems. For purposes of this Lease, "Holidays" means those
     federal or state holidays which Landlord, in its sole discretion,
     designates to Tenant as "Holidays" for purposes of this Lease, such
     designation being subject to change from time to time; provided, Landlord
     shall not designate any day as a Holiday

                                       17


     unless a substantial number of first-class Chicago office buildings
     recognize such day as a holiday. Tenant hereby acknowledges that the
     windows of the Premises are sealed, and that the temperature conditions in
     the Premises may cause the Premises to become uninhabitable during the
     times when Landlord is not required pursuant to this paragraph to furnish
     heat, ventilation or air conditioning, unless after hours heating,
     ventilating and/or cooling is provided to the Premises pursuant to Section
     8.4. Such condition of the Premises shall not constitute nor be deemed to
     be a breach or a violation of this Lease or of any provision hereof, nor
     shall it be deemed an eviction nor shall Tenant claim or be entitled to
     claim any abatement or reduction of Rent nor make any claim for any damages
     or compensation by reason of such condition of the Premises.

          (b)  Washroom facilities, not within the Premises, for use by Tenant
     in common with other tenants on the floor on multi-tenant floors.

          (c)  Janitor service in and about the Premises, Saturdays, Sundays and

     consumed.

          (d)  Automatic passenger elevator service in common with Landlord and
     other tenants, at all times, day and night, including Holidays. Landlord
     shall provide limited non-exclusive freight elevator service at such times
     as Landlord shall determine and upon payment of such uniform charges as
     Landlord may establish from time to time.

          (e)  Window washing of the inside and outside of all peripheral
     Building windows at such times as Landlord may determine, but at least two
     times per year.

     8.2  Interruption of Use.  Interruptions of any service to be provided by
          -------------------
Landlord under this Section 8 or of any utility or other services to the
Building or the Premises, in whole or in part caused by repairs, maintenance,
replacements, breakdowns, improvements, changes of service, alterations,
accidents, acts of God or an enemy, strikes, lockouts, labor controversies,
insurrections, riots, picketing (whether legal or illegal), laws, orders or
regulations of any federal, state, county or municipal authorities, any
accidents or casualties whatsoever, inability of Landlord to obtain electricity,
fuel, water or supplies, or by the act or default of Tenant or any person other
than Landlord, or by any cause or causes beyond the reasonable control of
Landlord, shall not be deemed an eviction or disturbance of Tenant's use and
possession of the Premises or any part thereof, or render Landlord liable for
damages (unless due to Landlord's negligence or willful misconduct) by abatement
or reduction of Rent or otherwise or relieve Tenant from performance of Tenant's
obligations under this Lease. In addition, Tenant agrees that compliance with
any mandatory or voluntary energy conservation measures or other legal
requirements instituted by any appropriate governmental authority shall not be
considered a violation of

                                       18


any terms of this Lease and shall not entitle Tenant to terminate this Lease or
require abatement or reduction of Rent hereunder. Landlord agrees to use
reasonable efforts to cause the restoration of services in the event of any
interruption described in this paragraph. Notwithstanding the foregoing, if an
interruption or cessation of utilities which renders the Premises untenantable
results from Landlord's breach of this Lease or the negligence or willful
misconduct of Landlord, or its employees, agents and contractors and the
Premises are not used by Tenant for the conduct of Tenant's business as a result
thereof for a period of five (5) consecutive business days, Base Rent and
applicable Operating Expenses shall be abated for the period which commences
five (5) business days after the date Tenant gives to Landlord notice of such
interruption until such utilities are restored or Tenant resumes using the
Premises, whichever is earlier. In the event of any dispute between the parties
as to whether Tenant is entitled to an abatement of Base Rent and Operating
Expenses, such dispute shall be resolved by the arbitration under the then
prevailing commercial rules of the American Arbitration Association, which
arbitration shall be conducted in Chicago, Illinois. Pending the final
determination of the arbitrator(s), Tenant shall continue paying the
installments of Base Rent and Operating Expenses as provided in this Lease. If
the arbitrator(s) determine that Tenant was entitled to an abatement of Base
Rent and/or Operating Expenses, Landlord shall promptly refund to Tenant the
amount which the arbitrator(s) determined is owing to Tenant.

     8.3  Tenant's Equipment/Overstandard Use/Electricity.
          -----------------------------------------------

          (a)  The Premises is separately metered for electricity and Tenant
     shall make arrangements with the utility company for provision of
     electrical service to the Premises. Tenant shall pay, when due, directly to
     the utility company all bills for electrical consumption in the Premises.
     Landlord shall not be liable for any interruption in electrical service or
     for the character or quality of electrical service provided to the
     Premises, unless due to its negligence or willful misconduct.

          Tenant shall not install or operate in the Premises any equipment or
     other machinery, other than a telephone system, facsimile machines,
     electric typewriters, word processing machines, adding machines, radios,
     televisions, tape recorders, Dictaphones, bookkeeping machines, clocks,
     standard size office copiers, mini-computers, computer servers customary
     for general office use, and other standard office machines requiring
     similarly low utility consumption, without (i) obtaining the prior written
     consent of Landlord, which consent shall not be unreasonably withheld or
     delayed but may be conditioned upon the payment by Tenant of Additional
     Rent for additional consumption of utilities, additional wiring or other
     expenses resulting therefrom, (ii) securing all necessary permits from
     governmental authorities and utility companies and furnishing copies
     thereof to Landlord, and (iii) complying with any other requirements
     reasonably imposed by Landlord. Tenant shall not install any equipment or
     machinery which may necessitate any changes, replacements or additions to
     or material changes in the use of the water, heating, plumbing, air
     conditioning or electrical systems of the

                                       19


     Building without obtaining the prior written consent of Landlord. Further,
     Tenant shall not place a load upon the floor of the Premises which exceeds
     the floor load per square foot which such floor was designed to carry.

          (b)  If at any time during the Lease Term, Tenant's connected
     electrical load from its use of equipment and fixtures (including
     incandescent lighting and power), as reasonably estimated by Landlord,
     exceeds the reasonable capacity available at the Premises (taking into
     account the electrical usage of Landlord and other tenants and occupants of
     the Building), then following notice to Tenant and a reasonable period in
     which Tenant may correct such situation, Landlord shall have the right to
     install additional transformers, distribution panels, wiring and other
     applicable equipment at the expense of Tenant. Landlord agrees to install
     such equipment at any time, at Tenant's expense, upon a written request
     from Tenant that such equipment be installed. None of the equipment so
     installed shall be deemed to be Tenant's property. In all events, the
     Premises shall be separately metered for all electrical usage at the
     Premises, including lighting, and Tenant shall pay all charges therefor
     prior to the date the same become delinquent.

          (c)  If business machines and equipment belonging to Tenant cause
     noise or vibration that may be transmitted to any part of the Building to
     such degree as to be objectionable to Landlord or to any tenant of the
     Building, Tenant shall install and maintain, at Tenant's expense, devices
     that eliminate the noise and vibration.

     8.4  Additional Services.  Landlord shall in no event be obligated to
          -------------------
furnish any services or utilities, other than those specified in Section 8.1
above; provided, so long as Tenant is not in default of any of its obligations
under this Lease, Landlord shall furnish after hours heating, ventilation and
air conditioning to the Premises upon such advance notice to Landlord by Tenant
as Landlord shall require of tenants generally. If Landlord furnishes services
or utilities requested by Tenant in addition to those specified in Section 8.1
(including heating, ventilating and air conditioning at times other than those
specified in paragraph (a) of Section 8.1), Tenant shall pay to Landlord
Landlord's then prevailing rates for such services and utilities within 30 days
after receipt of Landlord's invoices therefor. If Tenant shall fail to make any
such payment, Landlord may, upon five days' advance notice to Tenant, and in
addition to Landlord's other remedies under this Lease, discontinue any or all
of the additional services and utilities, including the furnishing of after-
hours heating, ventilating and air conditioning and such discontinuance shall
not be deemed to constitute an eviction or disturbance of Tenant's use and
possession of the Premises nor shall same relieve Tenant from paying Rent or
performing any of its obligations under this Lease.

     8.5  Building Directory.  Landlord shall list Tenant on the Building
          ------------------
directory. Any additional names requested by Tenant to be displayed in the
Building directory must be approved by Landlord and, if approved, will be
provided at the sole expense of Tenant.

                                       20

     ------------------------

     9.1  Landlord's Consent to Alterations.  Tenant shall not, without
          ---------------------------------
Landlord's prior written consent, permit any alteration, improvement, addition
or installation in or to the Premises (all of which is collectively referred to

paging systems or other similar systems, or the performance of any decorating,
painting and other similar work in the Premises. The construction of the initial
Tenant Improvements (as defined in Exhibit 2) to the Premises shall be governed
                                   ---------
by the terms of the Work Letter attached to this Lease as Exhibit 2, and not the
                                                          ---------
terms of this Section 9. Notwithstanding the foregoing, Tenant may, without
              ---------
obtaining Landlord's prior consent but with prior notice to Landlord, decorate
the interior of the Premises at Tenant's sole discretion; provided such
decorations do not involve structural changes or improvements to the Premises or
the Building, do not involve or affect any of the Building Systems, do not
exceed $10,000.00 in cost in any one instance, cannot be seen from the exterior
of the Building or from any common areas of the Building and are otherwise
performed in compliance with the provisions of this Article 9.

     9.2  Manner of Construction.  In the event Landlord consents to any Work,
          ----------------------
such Work shall be performed by contractors, subcontractors, and mechanics that
Landlord has consented to in advance, which consent shall not be unreasonably
withheld; conditioned or delayed, provided, Landlord reserves the right to cause
any portion of such Work which affects the Building's structure or any Building
system (such as the heating, ventilating and air conditioning systems, the
plumbing system, life safety and the electrical system) to be performed by
contractors, subcontractors and mechanics of Landlord's choosing, in which event
Tenant shall pay the reasonable cost of preparation of the plans and permits and
fees of said contractors, subcontractors and mechanics. Furthermore, Landlord
reserves the right to require Tenant to retain only union contractors. Before
commencement of any Work or delivery of any materials into the Premises or the
Building, Tenant shall furnish to Landlord, for its prior written approval,
architectural plans and specifications certified by a licensed architect or
engineer reasonably acceptable to Landlord, and such other documentation as
Landlord shall reasonably request. Tenant agrees to contract directly with such
approved contractors, subcontractors and mechanics. Tenant agrees to indemnify,
defend, protect and hold Landlord, its agents, partners, officers, servants and
employees forever harmless from and against all claims and liabilities of every
kind, nature and description which may arise out of or in any way be connected
with any such Work. Tenant shall pay the reasonable costs incurred by Landlord
in reviewing plans and materials submitted to Landlord for approval. In
addition, promptly after being billed therefor by Landlord, Tenant shall pay to
Landlord a supervisory fee equal to 5% of the cost of all Work. Landlord's
review of the plans and materials submitted to Landlord as set forth in this
Section 9.2, shall be for its sole purpose and shall not imply Landlord's review
of the same, or obligate Landlord to review the same, for quality, design, Code
compliance or other like matters. Accordingly, notwithstanding that any plans
and materials submitted to Landlord are reviewed by Landlord or its space
planner, architect, engineers and consultants, and notwithstanding any advice or
assistance which may be rendered to

                                       21


Tenant by Landlord or Landlord's space planner, architect, engineers, and
consultants, Landlord shall have no liability whatsoever in connection therewith
and shall not be responsible for any omissions or errors contained therein, and
Tenant's waiver and indemnity set forth in Section 14 of this Lease shall
specifically apply thereto. Tenant shall pay the cost of all such Work and the
cost of repairing, decorating and altering the Premises and the Building
occasioned by any such Work. In the event the cost of the Work exceeds Twenty-
Five Thousand and No/100 ($25,000.00) Dollars, Landlord shall have the right, as
a condition to approval, to require Tenant to provide reasonable security to
insure the payment of all costs of the Work. All alterations, improvements,
additions and installations to or on the Premises (including the initial Tenant
Improvements constructed pursuant to the Work Letter), if any, shall become part
of the Premises at the time of installation.

     9.3  Insurance; As-Built Plans.  Prior to the commencement of any Work or
          -------------------------
the delivery of any materials to the Building, Tenant shall submit to Landlord
for Landlord's approval, the names and addresses of all contractors (other than
those chosen by Landlord), contracts, necessary permits and licenses,
certificates of insurance (including, without limitation, builder's all-risk,
worker's compensation, commercial general liability and architect's professional
errors and omissions insurance) naming Landlord and Landlord's agents as
additional insureds and instruments of indemnification against any and all
claims, costs, expenses, damages and liabilities which may arise in connection
with the Work, all in such form and amount as shall be satisfactory to Landlord.
In addition, Landlord may, in its discretion, require Tenant to obtain a lien
and completion bond or other alternate form of security satisfactory to Landlord
in an amount sufficient to ensure the lien free completion of such Alterations
and naming Landlord as a co-obligee. All Work shall be done only at such time
and in such manner as Landlord may from time to time reasonably designate. Upon
completion of any Work, Tenant shall furnish Landlord with two sets of as-built
plans of the Work and with contractors' and subcontractors' affidavits, full and
final waivers of lien, and receipted paid bills covering all labor, services and
materials expended and used in connection with such Work. All Work shall comply
with all insurance requirements, all laws, ordinances, rules and regulations of
all governmental authorities, and all collective bargaining agreements
applicable to the Building, and shall be done in a good and workmanlike manner
and with the use of new high-quality grades of materials.

condition and repair, and agrees to keep the Premises in such condition.

     10.2  Tenant's Repair Obligations.  Except as provided in Section 10.3,
           ---------------------------
Tenant shall, during the Lease Term, at its own expense, keep the Premises,
including all improvements, fixtures and equipment therein, clean and safe and
in as good repair and condition as when all of the work described in the Work
Letter, if any, was completed (or as to subsequent work, as when such Work was
completed), ordinary wear and tear excepted. Tenant shall be responsible for all
damage or injury to the Premises or any other part of the Building or Property
and the systems and equipment thereof, whether requiring structural or
nonstructural repairs, caused by or resulting from carelessness, omission,
neglect or improper conduct of Tenant, Tenant's agents, employees, invitees or
licensees, or which arise out of any work, labor, service or equipment done for

work, labor, service or equipment performed or provided by Landlord) or arising
out of the installation, use or operation of the property or equipment of
Tenant. Tenant shall also be responsible for all damage to the Property, the
Building and the Premises caused by the moving of Tenant's fixtures, furniture
and equipment. Tenant shall promptly make, at Tenant's expense, all repairs in
and to the Premises for which Tenant is responsible, under the supervision of
Landlord and using only such contractors and subcontractors as Landlord has
approved, which approval shall not be unreasonably withheld. Any other repairs
in or to the Property or the Building or the facilities and systems thereof for
which Tenant is responsible shall be performed by contractors retained by
Landlord at Tenant's expense. In connection with all such repairs to the
Premises or other parts of the Building or Property, Tenant shall reimburse
Landlord within ten days of receipt of a bill therefor for Landlord's costs
incurred in connection with such work, together with a fee for supervising such
work (whether or not performed by Landlord) equal to 5% of the cost of such
work. Notwithstanding anything to the contrary in this Lease, Lessee's
obligation to repair or maintain shall not include the making of any structural

Building, the exterior windows of the Building, and, subject to the provisions
of Section 8, the electrical, plumbing, heating, ventilation and air
conditioning systems of the Building. Tenant agrees to give prompt notice of any
defective condition in the Premises for which Landlord may be responsible
hereunder. Inconvenience, annoyance or injury to business arising from Landlord
or others making repairs, alterations, additions or improvements in or to any
portion of the Property, the

                                       23


Building or the Premises or in and to the fixtures, appurtenances or equipment
thereof, shall not be deemed an eviction or disturbance of Tenant's use and
possession of the Premises or any part thereof, or render Landlord liable for
damages by abatement or reduction of Rent or otherwise or relieve Tenant from
performance of Tenant's obligations under this Lease. Landlord will use
reasonable efforts to schedule work in the Premises so as to minimize any
adverse effect thereof on Tenant's business. If Tenant requests that such work
be done after normal business hours, and if Landlord consents thereto (such
consent not to be unreasonably withheld), Landlord will cause such work to be
done after normal business hours and Tenant will pay the increased cost thereof
within ten days of Tenant's receipt of a bill therefor. Tenant hereby waives and
releases its right to make repairs at Landlord's expense under any law, statute,
or ordinance now or hereafter in effect.

known to the Landlord the combination of all combination locks in the Premises,
and shall, subject to Sections 12 and 13, return the Premises and all equipment
and fixtures of the Landlord therein to Landlord in as good condition as when
Tenant originally took possession (or as to subsequent Work, as when such Work
was completed), ordinary wear and tear excepted, failing which Landlord may
restore the Premises and such equipment and fixtures to such condition and the
Tenant shall pay the cost thereof to Landlord on demand.

     11.2  Removal of Property.  Upon termination of this Lease or of Tenant's
           -------------------
right to possession of the Premises, by lapse of time or otherwise, all
installations, additions, partitions, hardware, light fixtures, floor coverings,
non-trade fixtures and improvements, temporary or permanent, except movable
furniture and movable equipment belonging to Tenant, in or upon the Premises,
whether placed there by Tenant or Landlord, shall be Landlord's property and
shall remain upon the Premises, all without compensation, allowance or credit to
Tenant; provided, however, that if prior to any such termination Landlord so
directs by notice, Tenant, at Tenant's sole expense, shall, prior to such
termination or promptly thereafter, remove such of the installations, additions,
partitions, hardware, cabling and data lines, light fixtures, floor coverings,
non-trade fixtures and improvements placed in the Premises by or on behalf of
Tenant as are designated in such notice and repair any damage to the Premises
caused by such removal, failing which Landlord may remove the same and repair
the Premises, and Tenant shall pay the cost thereof to Landlord on demand.
Notwithstanding anything to the contrary in this Lease, Tenant shall not be
required to remove any alterations, additions, improvements or utility
installations for which Tenant has obtained Landlord's consent, unless Landlord
has indicated at the time of granting such consent that removal will be required
at the end of the Lease term.

                                       24


     11.3  Survival.  All obligations of Tenant under this Section 11 shall
           --------
survive the termination of this Lease, by lapse of time or otherwise.

12.  DAMAGE OR DESTRUCTION
     ---------------------

     12.1  Repair of Damage to Premises by Landlord.  Tenant shall promptly
           ----------------------------------------
notify Landlord of any damage to the Premises resulting from fire or any other
casualty. If the Premises or any common areas of the Building or Property
serving or providing access to the Premises shall be damaged by fire or other
casualty, Landlord shall promptly and diligently, subject to reasonable delays
for insurance adjustment or other matters beyond Landlord's reasonable control,
and subject to all other terms of this Section 12, restore the Premises and such
common areas. Such restoration shall be to substantially the same condition of
the Premises and such common areas prior to the casualty, except for
modifications required by zoning and building codes and other laws or by the
holder of any mortgage on the Building and/or the Property, or the lessor of any
ground or underlying lease with respect to the Building and/or the Property, or
any other modifications to such common areas deemed desirable by Landlord,
provided access to the Premises and any common restrooms serving the Premises
shall not be materially impaired. Notwithstanding any other provision of this
Lease, upon the occurrence of any damage to the Premises, Tenant shall assign to
Landlord (or to any party designated by Landlord) all insurance proceeds payable
to Tenant under Tenant's casualty insurance required under Section 15 of this
Lease, to the extent applicable to Landlord's restoration and Landlord shall
repair any injury or damage to the improvements at or in the Premises, whether
or not installed by Tenant or previously existing, including the Tenant
Improvements (as modified by any subsequent Work) installed in the Premises and
shall return such improvements to their original condition subject to 12.2
below. Landlord shall not be liable for any inconvenience or annoyance to Tenant
or its visitors, or injury to Tenant's business resulting in any way from such
damage or the repair thereof; provided however, that if such fire or other
casualty shall have damaged the Premises or common areas necessary to Tenant's
occupancy, and if such damage is not the result of the negligence or willful
misconduct of Tenant or Tenant's employees, contractors, licensees, or invitees,
Landlord shall allow Tenant a proportionate abatement of the Monthly Base Rent
and Tenant's Share of Direct Expenses to the extent the Premises are unfit for
occupancy for the purposes permitted under this Lease, and not occupied by
Tenant as a result thereof.

     12.2  Landlord's Option to Repair.  Notwithstanding the terms of Section
           ---------------------------
12.1 of this Lease, Landlord may elect not to rebuild and/or restore the
Premises, the Building and/or the common areas and instead terminate this Lease
by notifying Tenant in writing of such termination within 90 days after the date
of damage, but Landlord may so elect only if the Building and/or the common
areas shall be damaged by fire or other casualty or cause, whether or not the
Premises are affected, and one or more of the following conditions is present:
(i) repairs cannot reasonably be completed within 120 days of the date of damage
(when such repairs are made without the payment of overtime or other premiums);
(ii) the holder of any mortgage on the Property and/or Building or the lessor of

                                       25


any ground or underlying lease with respect to the Property and/or Building
shall require that the insurance proceeds or any portion thereof be used to
retire the mortgage debt, or shall terminate the ground or underlying lease, as
the case may be; or (iii) the damage is not fully covered, except for deductible
amounts, by Landlord's insurance policies.

     12.3  Waiver of Statutory Provisions.  The provisions of this Lease,
           ------------------------------
including this Section 12, constitute an express agreement between Landlord and
Tenant with respect to any and all damage to, or destruction of, all or any part
of the Premises, the Building or the Property and any statute or regulation of
the State of Illinois, with respect to any rights or obligations concerning
damage or destruction in the absence of an express agreement between the
parties, and any other statute or regulation, now or hereafter in effect, shall
have no application to this Lease or any damage or destruction to all or any
part of the Premises, the Building or the Property.

     12.4  Damage Near End of Term.  In the event that the Premises, the
           -----------------------
Building and/or any common areas of the Building or Property servicing or
providing access to the Premises or Building is destroyed or damaged to any
substantial extent during the last 6 months of the Lease Term, then
notwithstanding any other provision contained in this Section 12, both Landlord
and Tenant shall have the option to terminate this Lease by giving written
notice to Tenant of the exercise of such option within 30 days after such damage
or destruction, in which event this Lease shall cease and terminate as of the
date of such notice, Tenant shall pay the Monthly Base Rent and Tenant's Share
of Direct Expenses properly apportioned up to such date of damage, and both
parties hereto shall thereafter be freed and discharged of all further
obligations hereunder, except as provided for in provisions of this Lease which
by their terms survive the expiration or earlier termination of the Lease Term.

     12.5  Tenant's Right to Terminate.  Notwithstanding anything to the
           ---------------------------
contrary contained herein, if Tenant's use of the Premises is substantially
impaired due to any fire or other casualty for a period of more than one hundred
fifty (150) consecutive days after the date of such fire or other casualty,
Tenant shall have the right to terminate this Lease by giving written notice of
termination to Landlord at any time thereafter until Tenant's use of the
Premises is substantially restored; provided that any such termination shall not
be effective if the damage to the Premises shall have been substantially
repaired within thirty (30) days following Landlord's receipt of the
aforementioned written termination notice.

13.  EMINENT DOMAIN
     --------------

     13.1  Permanent Taking of Premises/Termination.  In the event that the
           ----------------------------------------
whole or a substantial part of the Premises shall be condemned or taken in any
manner for any public or quasi-public use (or sold under threat of such taking),
and as a result thereof, the remainder of the Premises cannot be used for the
same purpose as prior to such taking, the Lease Term shall terminate as of the
date possession is taken; provided, however, if Landlord elects to make
comparable space in the Building available to Tenant according

                                       26


to the terms and provisions of Section 26 of this Lease, Tenant shall accept
such space and this Lease shall not terminate but shall then apply to such
space.

     13.2  Partial Taking of Premises.  If less than a substantial part of the
           --------------------------
Premises shall be so condemned or taken (or sold under threat thereof) and after
such taking the Premises can be used for the same purposes as prior thereto as
reasonably determined by Tenant, the Lease Term shall cease only as to the part
so taken as of the date possession shall be taken by such authority, and Tenant
shall pay full Rent up to that date (with appropriate refund by Landlord of such
Rent attributable to the part so taken as may have been paid in advance for any
period subsequent to the date possession is taken) and thereafter Monthly Base
Rent and Tenant's Share shall be equitably adjusted to reflect the reduction in
the Premises by reason of such taking. Landlord shall, at its expense, make all
necessary repairs or alterations to the Building so as to constitute the
remaining Premises a complete architectural unit, provided that Landlord shall
not be obligated to undertake any such repairs or alterations if the cost
thereof exceeds the award resulting from such taking. If Landlord fails to fund
such excess cost in order to complete such repairs or alterations, Tenant shall
have the right to terminate this Lease by giving Landlord notice thereof;
provided, if Landlord notifies Tenant within ten days after receiving Tenant's
notice that Landlord shall fund such excess cost and promptly complete such
repairs or alterations, then this Lease shall continue as if Tenant had not
given Landlord such notice of termination.

     13.3  Taking Building.  If part of the Building or common areas of the
           ---------------
Building or Property servicing or providing access to the Building shall be so
condemned or taken (or sold under threat thereof), or if any adjacent property
or street shall be condemned or improved by a public or quasi-public authority
in such a manner as to alter the use of any part of the Premises or the Building
and, in the opinion of Landlord, the Building or any part thereof should be
altered, demolished or restored in such a way as to materially alter the
Premises or access to the Premises or Building, Landlord may terminate this
Lease by notifying Tenant of such termination within 60 days following such
taking of possession or improvement by such public or quasi-public authority,
and this Lease shall expire on the date specified in the notice of termination,
which shall be not less than 60 days after the giving of such notice, as fully
and completely as if such date were the date hereinbefore set forth as the
expiration of the Lease Term, and the Monthly Base Rent and Tenant's Share of
Direct Expenses shall be apportioned as of such date.

     13.4  Condemnation Award.  Landlord shall be entitled to receive the entire
           ------------------
award, including the damages for the property taken and damages to the
remainder, with respect to any condemnation proceedings affecting the Building
and/or Property. Tenant agrees not to make any claim against Landlord or the
condemning authority for any portion of such award or compensation, whether
attributable to the value of any unexpired portion of the Lease Term, the loss
of profits' goodwill, leasehold improvements or otherwise, Tenant irrevocably
assigning any and all such claims to Landlord. Nothing herein contained shall be
deemed or construed to prevent Tenant from prosecuting a separate claim against
the

                                       27


condemning authority for the value of any fixtures or improvements installed in
or made to the premises by Tenant, at its cost, or for its costs of moving or
loss of business by reason of such condemnation; provided that any such claim
does not reduce the amount of Landlord's award.

14.  WAIVER AND INDEMNIFICATION
     --------------------------

     14.1  Release and Waiver.  To the extent not expressly prohibited by law,
           ------------------
Tenant releases Landlord, its beneficiaries, all Mortgagees (as defined in
Section 24), and their respective agents, partners, shareholders, members,
directors, managers, officers, servants and employees (collectively, "Landlord
and its Affiliates"), from and waives all claims for damages to person or
property sustained by Tenant or by any occupant of the Premises or the Building,
or by any other person, resulting directly or indirectly from fire or other
casualty, any other cause or any existing or future condition, defect, manner or
thing in the Premises, the Building, the Property or any part thereof, or from
any equipment or appurtenances therein, or from any accident in or about the
Building or Property, or from any act or neglect of any tenant or other occupant
of the Building or Property or of any other person. This section shall apply
especially, but not exclusively, to damage caused by water, earth movement,
snow, frost, steam, excessive heat or cold, sewage, gas, odors or noise, or the
bursting or leaking of pipes or plumbing fixtures, falling plaster, broken
glass, sprinkling or air conditioning devices or equipment, or flooding of
basements, and shall apply without distinction as to the person whose act or
neglect was responsible for the damage and whether the damage was due to any of
the acts specifically enumerated above, or from any other thing or circumstance,
whether of a like nature or of a wholly different nature. All personal property
belonging to Tenant or any occupant of the Premises that is in the Premises or
the Building or on the Property shall be there at the risk of Tenant or other
person only and Landlord and its Affiliates shall not be liable for damage
thereto or theft or misappropriation thereof.

     14.2  Indemnification.  To the extent not expressly prohibited by law,
           ---------------
Tenant agrees to protect, hold harmless and indemnify Landlord and its
Affiliates from and against any and all claims, losses, expenses and
liabilities, including without limitation reasonable attorneys' fees, for
injuries to all persons and damage to or misappropriation or loss of property
occurring in the Premises due to theft or other crimes occurring in the Premises
and for injuries to all persons and damage to or loss of property arising from
Tenant's use or occupancy of the Premises or the conduct of its business or from
activity, work, or thing done, permitted or suffered by Tenant in or about the
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 due to any other act or omission of Tenant, its
agents, employees, contractors, licensees, clients, customers or invitees. In
the event any action or proceeding is brought against Landlord and its
Affiliates (or any or all of them) by reason of any such indemnified claims,
losses, expenses and liabilities, then, upon notice from Landlord, Tenant
covenants to defend such action or proceeding by counsel reasonably satisfactory
to such indemnitee.

                                       28


     14.3  Tenant's Liability for Damage.  If any damage to the Premises, the
           -----------------------------
Building or the Property, or any equipment or appurtenance therein, whether
belonging to Landlord or to other tenants of the Building or Property, results
from any act or neglect of Tenant, its agents, employees, guests or invitees,
Tenant shall be liable therefor and Landlord may, at Landlord's option, repair
such damage, and Tenant shall, upon demand by Landlord, reimburse Landlord for
the total cost of such repairs in excess of amounts, if any, paid to Landlord
under insurance covering such repairs. If Landlord elects not to repair such
damage, Tenant shall promptly repair such damages at its own cost and in
accordance with the provisions of Section 9 as if such repair constituted Work
under Section 9. If Tenant occupies space in which there is exterior glass, then
Tenant shall be responsible for the damage, breakage or repair of such glass
caused by Tenant or Tenant's employees, agents, contractors, licensees, clients,
customers or invitees, except to the extent that such loss or damage is
recoverable under Landlord's insurance, if any.

     14.4  Landlord's Liability.  Notwithstanding any provision of this Lease to
           --------------------
the contrary other than Section 15, Tenant shall not be deemed to exempt
Landlord from liability for damage or injury to persons or damage to property to
the extent such damage (i) is actually caused by or results from the negligence
or willful misconduct of Landlord, its agents, servants or employees in the
operation or maintenance of the Building or a breach by Landlord of its
obligations hereunder, and (ii) is not otherwise covered by insurance maintained
by Tenant under this Lease (or would have been so covered had Tenant maintained
insurance as required under this Lease).

     14.5  Survival.  The provisions of this Section 14 shall survive the
           --------
expiration or sooner termination of this Lease.

15.  INSURANCE

                                  which the Premises are located, and in
                                  any event sufficient to protect
                                  Tenant from liability


          15.1.2  Physical Damage Insurance covering all office furniture, trade
fixtures, office equipment, merchandise and all other items of Tenant's property
on the Premises. Such insurance shall be written on an "all-risk" of physical

for depreciation of the covered items and in amount that meet any co-insurance
clauses of the policies of insurance and shall include a vandalism and malicious
mischief endorsement and sprinkler leakage coverage.

          15.1.3  Business interruption, loss of income and extra expense
insurance in amounts sufficient to pay for Tenant's expenses and lost income

          15.1.4  Form of Policies.  The minimum limits of policies of insurance
                  ----------------
required of Tenant under this Lease shall in no event limit the liability of
Tenant under this Lease. Such insurance shall (i) name Landlord, Landlord's
beneficiaries, Landlord's Management Agent, the Mortgagees, any ground or

as additional insureds, (ii) specifically cover the liability assumed by Tenant

carried by Landlord is excess and is non-contributing with any insurance
requirement of Tenant; (v) provide that said insurance shall not be canceled or
coverage changed unless 30 days' prior written notice shall have been given to
Landlord, Landlord's Management Agent, and any Mortgagee or ground or underlying
lessor of the Building; and (vi) contain a cross-liability endorsement or
severability of interest clause acceptable to Landlord. Tenant shall deliver
said policy

                                       30


or policies or certificates thereof to Landlord on or before the
Commencement Date and at least 30 days before the expiration dates thereof.  In
the event Tenant shall fail to procure such insurance, or to deliver such
policies or certificates, Landlord may, at its option, procure such policies for
the account of Tenant, and the cost thereof shall be paid to Landlord as
Additional Rent within five days after delivery to Tenant of bills therefor.

     15.2  Subrogation.  Landlord and Tenant agree to have their respective
           -----------
insurance companies issuing property damage insurance waive any rights of
subrogation that such companies may have against Landlord or Tenant, as the case
may be provided, however, the foregoing waiver shall not be operative in any
case where the effect thereof is to invalidate any insurance coverage of the
waiving party and provided further that Landlord and Tenant each agree to give
written notice of the terms of this mutual waiver to each insurance company
which has issued, or in the future may issue, property damage insurance to it,
and to have said insurance policies properly endorsed, if necessary, to prevent
the invalidation of said insurance coverage by reason of said waiver.  Landlord
and Tenant hereby waive any right that either may have against the other on
account of any loss or damage to their respective property to the extent such
loss or damage is insurable under policies of insurance for fire and all-risk
coverage, theft, general liability, or other similar insurance.

     15.3  Additional Insurance Obligations.  Tenant shall carry and maintain
           --------------------------------
during the entire Lease Term, at Tenant's sole cost and expense, the insurance
required to be carried by Tenant pursuant to this Section 15.  In addition to
Tenant's obligation in Section 6, Tenant shall, at Tenant's expense, comply as
to the Premises with all insurance company requirements pertaining to the use of
the Premises.  If Tenant's conduct or use of the Premises causes any increase in
the premiums for insurance policies maintained by Landlord, then Tenant shall
reimburse Landlord for any such increase.

16.  LANDLORD'S RIGHT OF ACCESS
     --------------------------

     16.1  Landlord's Entry.  Landlord and its representatives shall have the
           ----------------
right to enter the Premises at all reasonable times to inspect the same, to
perform janitorial and cleaning services, to make repairs, alterations,
additions or improvements, to maintain the Premises or the Building,
specifically including, but without limiting the generality of the foregoing, to
make repairs, additions or alterations within the Premises to mechanical,
electrical and other facilities serving other premises in the Building, to make
repairs, additions or alterations to the Building and/or Property which may
change, eliminate or remove common areas, parking areas, if any, or the method
of ingress to or egress from the Building and such areas, to convert common
areas into leaseable areas, or otherwise alter, repair or reconstruct the common
areas or change the use thereof, and to perform any acts related to the safety,
protection, preservation, reletting, sale or improvement of the Premises, the
Building and/or the Property and to post such reasonable notices as Landlord may
desire to protect its rights.  Landlord and its representatives shall have the
right to enter the Premises at all reasonable times to exhibit the Premises to
prospective

                                       31


purchasers, mortgagees or lessors of the Building and/or Property, and, during
the 180 days prior to the expiration of the Lease Term, to exhibit the Premises
to prospective tenants. In the event the Premises are vacant, Landlord may place
upon the doors or in the windows of the Premises any usual or ordinary "To Let,"
"To Lease," or "For Rent" signs. Tenant shall permit Landlord to erect, use,
maintain and repair pipes, cables, conduit, plumbing, columns, shafts, vents and
wires, in, to and through the Premises, to the extent Landlord may now or
hereafter deem necessary or appropriate for the proper operation, maintenance
and repair of the Property and any portion of the Premises. Landlord and its
representatives, for any of the foregoing purposes, may enter on and about the
Premises and the Building with such material as Landlord may deem necessary, may
erect scaffolding and all other necessary structures on or about the Premises,
the Building and the Property and may close or temporarily suspend operations of
entrances, doors, corridors, elevators, driveways, parking areas, loading docks
or other facilities. Tenant waives any claim for damages, including the loss of
business resulting therefrom, and agrees to pay Landlord for overtime and other
expenses incurred if such work is done other than during ordinary business hours
at Tenant's request. Notwithstanding anything in this Lease to the contrary,
except with respect to an emergency, Landlord shall endeavor to provide Tenant
with at least 24 hours' prior actual notice (which need not be in writing)
before entering the Premises. In the event of an emergency, the determination of
which shall require Landlord to be reasonable, Landlord shall, based on the
circumstances, endeavor to provide Tenant with notice (which need not be in
writing) of any contemplated entry upon the Premises. In the event of any entry
by Landlord onto the Premises, Landlord shall minimize, to the extent feasible,
interference with the conduct of Tenant's business.

     16.2  Additional Landlord's Rights.  Landlord shall also have the right to
           ----------------------------
take all material into the Premises that may be required for the purposes set
forth in the foregoing Section 16.1 without the same constituting a constructive
eviction of Tenant, in whole or in part and Rent shall not abate (except as
provided in Section 12) while said repairs, alterations, improvements or
additions are being made, by reason of loss or interruption of business of
Tenant, or otherwise.  Landlord shall, to the extent feasible, minimize
disruption to Tenant's use of the Premises in connection with any such entry.
If Tenant shall not be personally present to open and permit entry into the
Premises, at any time, when for any reason entry therein shall be necessary or
desirable, Landlord or Landlord's agents may enter the Premises by a master key,
or may forcibly enter the same, without rendering Landlord or such agents liable
therefor (if during such entry Landlord or Landlord's agents shall accord
reasonable care to Tenant's property), and without in any manner affecting the
obligations and covenants of Tenant under this Lease.  Landlord shall also have
the right at any time, without the same constituting a constructive eviction and
without incurring any liability to Tenant therefor, to change the arrangement or
location of entrances or passageways, doors and doorways, corridors, elevators,
stairs, toilets or other public parts of the Building or Property, and to close
entrances, doors, corridors, elevators, plaza or other facilities so long as the
Premises are reasonably accessible and usable.  Landlord shall not be liable to
Tenant for any expense, injury, loss or damage resulting

                                       32


from work done in or upon, or the use of, any adjacent or nearby building, land,
street, alley or underground vault or passageway.

     16.3  Scheduling.  Landlord will use reasonable efforts to schedule the
           ----------
work referred to in Sections 16.1 and 16.2 to be done in the Premises so as to
minimize any adverse effect thereof on Tenant's business, and if Tenant
reasonably requests and Landlord consents thereto (which consent shall not be
unreasonably withheld, conditioned or delayed), Landlord will cause such work to
be done after normal business hours and Tenant shall pay the increased cost
thereof within ten days after Tenant's receipt of a bill therefor.

17.  RIGHTS RESERVED TO LANDLORD
     ---------------------------

     Landlord shall have the following rights exercisable without notice and
without liability to Tenant for damage or injury to property, person or business
(all claims for damage being hereby waived and released by Tenant) and without
effecting an eviction or disturbance of Tenants use or possession or giving rise
to any claim for set-offs or abatement of Rent:

           (a) To change the name or street address of the Building or Property,
     or the suite number of the Premises;

           (b) To install and maintain signs on the exterior and interior of the

           (c) To designate all sources furnishing sign painting and lettering,
     towels, coffee cart service, vending machines, or toilet supplies used or
     consumed in the common areas or facilities of the Building and/or Property;

           (d) To have pass keys to the Premises;

           (e) To grant to anyone the exclusive right to conduct any business or
     render any service in the Building or Property, provided such exclusive
     right shall not operate to exclude Tenant from the use expressly permitted
     by this Lease;

           (f) To have access to all mail chutes or boxes according to the rules
     of the United States Postal Service;

           (g) To require all persons entering or leaving the Building during
     such hours as Landlord may from time to time reasonably determine to
     identify themselves to a watchman by registration or otherwise, and to
     establish their right to enter or leave and to exclude or expel any
     peddler, solicitor or beggar at any time from the Premises, the Building
     and/or the Property; and

                                       33


           (h) To close the Building between the hours of 6:00 p.m. and 7:00 am.
     the following day on weekdays, 1:00 p.m. on Saturdays, and all day on
     Sundays and Holidays, or at such other reasonable times as Landlord may
     determine, subject, however, to Tenant's right to admittance to the
     Premises at all times (including Holidays, but excluding emergencies) under
     such regulations as shall be prescribed from time to time by Landlord in
     its reasonable discretion.

18.  ABANDONMENT
     -----------

     Tenant shall not abandon the Premises at any time during the Lease Term.
Any reentry by Landlord following abandonment by Tenant shall not, unless
Landlord so elects in a written notice to Tenant, constitute or be deemed to
constitute acceptance by Landlord of a surrender of this Lease, but rather, upon
such abandonment, Tenant's right to possession of the Premises shall cease but
Tenant shall remain liable for all of its obligations under this Lease.  Without
limitation of the foregoing, upon any such abandonment, Landlord shall have the
remedies provided for in Section 21.  If Tenant shall abandon or surrender the
Premises or be dispossessed by process of law or otherwise during the Lease Term
or at the termination of the Lease Term, any personal property left on the
Premises shall be deemed to be abandoned at the option of Landlord, and title
thereto shall pass to Landlord under this Lease, which shall constitute a bill
of sale.  For purposes of this Lease, and at the option of Landlord, the
Premises shall be deemed vacated or abandoned if Tenant, or an agent or employee
of Tenant, shall not have conducted Tenant's ordinary business upon the Premises
during any period of 60 consecutive days.

19.  TRANSFER OF LANDLORD'S INTEREST; LIABILITY OF LANDLORD
     ------------------------------------------------------

     Landlord hereby reserves the right to sell, assign or transfer this Lease.
In such event this Lease shall remain in full force and effect, subject to the
performance by Tenant of all the terms, covenants and conditions on its part to
be performed, and provided either Landlord continues as, or such assignee or
transferee becomes, the Landlord hereunder.  In the event that such assignee or
transferee agrees to perform all the terms, covenants and conditions of Landlord
pursuant to this Lease which are to be performed by Landlord from and after the
effective date of such sale, assignment or transfer of this Lease (as the case
may be), then, upon any such sale, assignment or transfer, other than merely as
security, Tenant agrees to look solely to the responsibility of assignee or
transferee with respect to all matters in connection with this Lease and the
transferor Landlord shall be released from any further obligations hereunder
that arise subsequent to the date of such sale, assignment or transfer.

20.  TRANSFER OF TENANT'S INTEREST
     -----------------------------

     20.1  Transfers.  Tenant shall not sell, assign, encumber, mortgage or
           ---------
transfer this Lease or any interest therein, sublet or permit the occupancy or
use by others of the

                                       34


Premises or any part thereof, or allow any transfer hereof or any lien upon
Tenant's interest by operation of law or otherwise (collectively, a "Transfer"),
without the prior written consent of Landlord, which, except as otherwise
provided in this Section 20.1, Landlord may withhold in the exercise of its
absolute discretion, provided that if Landlord, upon receiving Tenant's Notice
(defined below) of a proposed subletting or assignment, does not elect to
Recapture (as defined below), Landlord shall not unreasonably withhold,
condition or delay its consent to such subletting or assignment. Any Transfer
which is not in compliance with the provisions of this Section 20 shall, at the
option of Landlord, be void and of no force or effect. Tenant shall, by written
notice, in the form specified in the following sentence ("Tenant's Notice"),
advise Landlord of Tenant's intention on a stated date (which shall not be less
than 60 days after the date of Tenant's Notice) to sublet any part or all of the
Premises for the balance or any part of the Lease Term or to assign its interest
in this Lease, and, in such event, Landlord shall have the right, to be
exercised by giving written notice to Tenant within 30 days after receipt of
Tenant's Notice, to recapture ("Recapture") the space described in Tenant's
Notice and such notice of Recapture shall, if given, cancel and terminate this
Lease with respect to the space therein described as of the date stated in
Tenant's Notice. Tenant's Notice shall state the name and address of the
proposed subtenant or assignee; the nature of proposed subtenant or assignee's
business; and a description of that portion of the Premises to be occupied,
including the number of square feet of net rentable area within that portion and
a true and complete copy of the proposed sublease or assignment and all related
documentation, and current credit reports and financial statements of the
proposed subtenant or assignee, shall be delivered to Landlord with Tenant's
Notice. If Tenant's Notice shall cover all of the space hereby demised, and
Landlord shall elect to give the aforesaid notice of Recapture with respect
thereto, then the Lease Term shall expire and end on the date stated in Tenant's
Notice as fully and completely as if that date had been herein definitely fixed
for the expiration of the Lease Term. If, however, this Lease is terminated
pursuant to the foregoing with respect to less than the entire Premises, the
Monthly Base Rent and Tenant's Share then in effect shall be adjusted on the
basis of the number of rentable square feet retained by Tenant in proportion to
the original rentable square feet of the Premises, and this Lease as so amended
shall continue thereafter in full force and effect. In such event, Landlord
shall pay the cost of erecting demising walls and public corridors and making
other required modifications to physically separate the portion of the Premises
remaining subject to this Lease from the rest of the Premises. Without limiting
Landlord's right to reasonably withhold its consent to a proposed subletting or
assignment, the withholding of such consent will be deemed reasonable if:

           (a) in the reasonable judgment of Landlord, the subtenant or assignee
     (i) is of a character or engaged in a business or proposes to use the
     Premises in a manner which is not in keeping with the standards of Landlord
     for the Building, or (ii) has an unfavorable reputation or credit standing;

                                       35


           (b) either the area of the Premises to be sublet or the remaining
     area of the Premises is not regular in shape with appropriate means of
     ingress and egress suitable for normal renting purposes;

           (c) a direct result of such subletting would be that more than six
     tenants would be occupying the floor(s) of the Building on which the
     Premises is located;

           (d) the transferee is either a government agency or instrumentality
     thereof;

           (e) the proposed Transfer would cause Landlord to be in violation of
     another lease or agreement to which the Landlord is a party or would give
     an occupant of the Property a right to cancel its lease;

           (f) the terms of the proposed Transfer will allow the transferee to
     exercise a right of renewal, right of expansion, right of first offer, or
     other similar right held by Tenant (or will allow the transferee to occupy
     space leased by Tenant pursuant to such right);

           (g) Tenant is in default under this Lease;

           (h) such proposed assignment or subletting is to an existing tenant
     of the Property (or any affiliate of an existing tenant) or to any person
     or party with whom Landlord is in the process of negotiating a lease of
     space in the Property;

           (i) the transferee intends to use the portion of the Premises which
     is subject to the Transfer for purposes not permitted under this Lease;

           (j) such proposed assignment of subletting would result in a
     violation of any applicable law, ordinance or government regulation;

           (k) such proposed assignee or subtenant is a high traffic tenant or
     is engaged in any type of sales where the public is invited to enter and
     use the Premises;

           (l) the proposed assignee or subtenant is a trade or labor union
     office;

           (m) the proposed assignee or subtenant will be using any portion of
     the Premises as an educational or training facility or is in the primary
     business of providing education or training; or

           (n) the proposed assignee or subtenant is an employment office.

                                       36


Each time Tenant requests Landlord's consent for any assignment of this Lease or
any sublease of all or any portion of the Premises, Tenant shall pay to Landlord
the actual reasonable costs, charges and expenses (including reasonable
attorneys' fees) incurred by Landlord in connection with such request and
Landlord's review of the proposed assignment or sublease as provided in Section
21.6 of this Lease, whether or not such consent is given; such payment shall be
made by Tenant to Landlord within ten days after demand by Landlord.

     Notwithstanding anything herein to the contrary, Tenant shall have the
right, without obtaining Landlord's consent, to assign this Lease or sublease
the Premises to a Related Entity (as hereinafter defined), subject to compliance
with the terms hereof. Within fifteen (15) days following the assignment of this
Lease to a Related Entity, and as a condition to the effectiveness thereof,
Tenant shall deliver to Landlord a fully executed Assignment and Assumption
Agreement pursuant to which the Tenant assigns to the Related Entity all of the
transferring Tenant's right, title and interest in this Lease and the Related
Entity assumes all of the Tenant's obligations and liabilities under this Lease.
The form and substance of the Assignment and Assumption Agreement shall be
reasonably acceptable to Landlord. No assignment of this Lease to a Related
Entity shall serve to release the assigning Tenant from any of its obligations
or liabilities under this Lease. Within fifteen (15) days following the sublease
of the Premises to a Related Entity and as a condition to the effectiveness
thereof, Tenant shall deliver to Landlord a fully executed sublease agreement
which shall be reasonably acceptable to Landlord in form and substance. No
sublease shall serve to release Tenant from any of its obligations or
liabilities under this Lease. The term "Related Entity" shall mean a
corporation, partnership, limited liability company or other entity that
controls, is controlled by or is under common control with Tenant. The term
"control" shall mean with respect to (a) a corporation, the ownership of more
than fifty (50%) percent of the issued and outstanding voting stock together
with the right to manage the affairs of the corporation and (b) with respect to
a partnership, limited liability company or other entity, the ownership of more
than fifty (50%) percent of the legal and equitable interests, together with the
right to manage the affairs of the partnership, limited liability company or
other entity.

     20.2  Excess Rent; Effect of Transfer.  If Tenant shall sublet or assign
           -------------------------------
the Premises or any part thereof or assign any interest in this Lease at a
rental rate (or additional consideration) in excess of the then current Monthly
Base Rent and amount of Direct Expense payments per rentable square foot, fifty
(50%) percent of all such excess proceeds ("Excess Proceeds") shall be and
become the property of Landlord and shall be paid to Landlord as it is received
by Tenant after first offsetting Tenant's reasonable out-of-pocket costs and
expenses of such assignment or subletting.  Tenant shall furnish Landlord with a
statement executed by Tenant's chief financial officer, setting forth in detail
the computation of all such proceeds and Landlord or its representatives shall
have access to the books, records and papers of Tenant in relation thereto and
shall have the right to make copies thereof.  Any non-monetary consideration
shall be paid to Landlord in such form as is satisfactory to Landlord.  If
Tenant shall assign or sublet the Premises or any

                                       37


part thereof, (i) Tenant shall be responsible for all actions and neglect of the
assignee or subtenant and its officers, partners, employees, contractors,
agents, licensees, clients, customers and invitees as if such actions and
neglect had been committed or omitted by Tenant, (ii) with respect to all
obligations and responsibilities of Tenant under this Lease, all references to
Tenant shall be deemed to include any assignee or subtenant, and all references
to Tenant's officers, partners, employees, contractors, agents, licensees,
clients, customers or invitees shall be deemed to include, respectively, each
assignee's or subtenant's officers, partners, employees, contractors, agents,
licensees, clients, customers and invitees, and (iii) each waiver made by Tenant
under this Lease shall be deemed to have also been made by each such assignee or
subtenant. Nothing in this Section 20.2 shall be construed to relieve Tenant
from the obligation to obtain Landlord's prior written consent to any proposed
sublease or assignment.

     20.3  Continuing Liability.  The consent by Landlord to any Transfer shall
           --------------------
not be construed as a waiver or release of Tenant from liability for the
performance of all covenants and obligations to be performed by Tenant under
this Lease, and Tenant shall remain liable therefor, nor shall the collection or
acceptance of Rent from any assignee, subtenant, transferee or occupant
constitute a waiver or release of Tenant from any of its obligations or
liabilities under this Lease.  Any consent given by Landlord to a Transfer
pursuant to this Section 20 shall not be construed as relieving Tenant from the
obligation of obtaining Landlord's prior written consent to any subsequent
Transfer.

     20.4  Additional Transfers.
           --------------------

           (a) If Tenant is a partnership or limited liability company, a
     withdrawal or change, whether voluntary, involuntary or by operation of law
     or in one or more transactions, of partners or members owning directly or
     indirectly a controlling interest in Tenant, or the dissolution of the
     partnership or limited liability company, without immediate reconstitution
     thereof, or the change or conversion of Tenant to a limited liability
     company or limited liability partnership, shall be deemed an assignment of
     this Lease and subject to the provisions of this Section 20.  If Tenant is
     a corporation, any dissolution, merger, consolidation or other
     reorganization of Tenant, or the sale, transfer or redemption of a direct
     or indirect controlling interest in the capital stock of Tenant, in one or
     more transactions, shall be deemed a voluntary assignment of this Lease and
     subject to the provisions of this Section 20.  However, the preceding
     sentence shall not apply to corporations the stock of which is traded
     through a national or regional exchange or over-the-counter.  Neither this
     Lease nor any interest therein nor any estate created thereby shall pass by
     operation of law or otherwise to any trustee, custodian or receiver in
     bankruptcy of Tenant or any assignee for the assignment of the benefit of
     creditors of Tenant.

           (b) The provisions of this Section 20.4 shall not apply to
     transactions with a corporation into or with which Tenant is merged or
     consolidated or to which substantially all of Tenant's assets are
     transferred provided that in any of such

                                       38


     events (i) the successor to Tenant has a net worth computed in accordance
     with generally accepted accounting principles at least equal to the greater
     of (1) the net worth of Tenant immediately prior to such merger,
     consolidation or transfer, or (2) the net worth of Tenant herein named on
     the date of this lease, and proof satisfactory to Landlord of such net
     worth shall have been delivered to Landlord at least fifteen (15) days
     prior to the effective date of such transaction, (ii) such merger,
     consolidation or transfer is for a good business purpose and not
     principally for the purpose of transferring the leasehold created hereby,
     and (iii) the liabilities of Tenant under this Lease are assumed by the
     successor to Tenant, whether by operation of law or by the effective
     provisions contained in the instruments of merger, consolidation, transfer
     or assignment.

21.  TENANT'S DEFAULT; LANDLORD'S RIGHTS AND REMEDIES
     ------------------------------------------------

     21.1  Events of Default.  The occurrence of any one or more of the
           -----------------
following matters constitutes a default ("Default") by Tenant under this Lease:

           (a) Failure by Tenant to pay within five business days following
     written notice of delinquency, any Rent or any other amounts due and
     payable by Tenant under this Lease or under any other agreement between
     Landlord and Tenant;

           (b) Failure by Tenant to observe or perform any of the covenants in
     this Lease in respect to assignment, subletting or other Transfers;

           (c) Abandonment of the Premises as prohibited in Section 18;

     Landlord any hazardous condition that Tenant has created in violation of
     law or of this Lease;

           (e) Failure by Tenant to observe or perform any other covenant,
     agreement, condition or provision of this Lease, if such failure shall
     continue for ten days after written notice thereof to Tenant by Landlord
     provided, said ten day period shall be extended, if Tenant commences to
     cure said failure within said ten day period, said failure is not capable
     of being cured within said ten day period, and Tenant diligently and
     continuously prosecutes the cure thereof to completion;

           (f) The levy upon or the attachment by legal process of the leasehold
     interest of Tenant, or the filing or creation of a lien in respect of such
     leasehold interest;

           (g) Tenant becomes insolvent or bankrupt or admits in writing its
     inability to pay its debts as they mature, makes an assignment for the
     benefit of creditors,

                                       39


     or applies for or consents to the appointment of a trustee or receiver for
     itself or for all or a part of its property;

           (h) Proceedings for the appointment of a trustee, custodian or
     receiver of Tenant or for all or a part of Tenant's property are filed
     against Tenant or such guarantor and are not dismissed within sixty (60)
     days;

           (i) Proceedings in bankruptcy, or other proceedings for relief under
     any law for the relief of debtors, are instituted by or against Tenant,
     and, if instituted against Tenant, are allowed against or are consented to
     by Tenant or are not dismissed within sixty (60) days thereof;

           (j) The rejection of this Lease under Section 235 of Title 11 of the
     United States Code;

           (k) Tenant shall repeatedly default in the timely payment of Rent or
     any other charges required to be paid, or shall repeatedly default in
     keeping, observing or performing any other covenant, agreement, condition
     or provision of this Lease, whether or not Tenant shall timely cure any
     such payment or other default.  For the purposes of this subsection, the
     occurrence of similar defaults three times during any 12 month period shall
     constitute a repeated default;

           (l) Tenant dissolves or winds up its business;

           (m) any representation or warranty made by Tenant is incorrect or
     misleading in any material respect;

     Any notice periods provided for under this Section 21.1 shall run
concurrently with any statutory notice periods and any notice given hereunder
may be given simultaneously with or incorporated into any such statutory notice.

     21.2  Remedies Upon Default.  Upon the occurrence of a Default by Tenant,
           ---------------------
Landlord shall have, in addition to any other remedies available to Landlord at
law or in equity, the option to pursue any one or more of the following
remedies, each and all of which shall be cumulative and nonexclusive, without
any notice or demand whatsoever.

           (a) Landlord may terminate this Lease, in which event Tenant shall
     immediately surrender the Premises to Landlord, and if Tenant fails to do
     so, Landlord may, without prejudice to any other remedy which it may have
     for possession or arrearages in rent, enter upon and take possession of the
     Premises and expel or remove Tenant and any other person who may be
     occupying the Premises or any part thereof, without being liable for
     prosecution or any claim or damages therefor, and Landlord may recover from
     Tenant the following:

                                       40


                    (i)    The worth at the time of award of any unpaid rent
          which has been earned at the time of such termination; plus

                    (ii)   The worth at the time of award of the amount by which
          the unpaid rent for the balance of the Lease Term after the
          termination exceeds the amount of such rental loss that Tenant proves
          could have been reasonably avoided; plus

                    (iii)  Any other amount necessary to compensate Landlord for
          all the detriment proximately caused by Tenant's failure to perform
          its obligations under this Lease, specifically including but not
          limited to, brokerage commissions and advertising expenses incurred,
          expenses of remodeling the Premises or any portion thereof for a new
          tenant, whether for the same or a different use, and any special
          concessions made to obtain a new tenant; and

                    (iv)   At Landlord's election, such other amounts in
          addition to or in lieu of the foregoing as may be permitted from time
          to time by applicable law.

     The term "rent" as used in this Section 21.2 shall be deemed to be and to
     mean all sums of every nature required to be paid by Tenant pursuant to the
     terms of this Lease, whether to Landlord or to others.  As used in Section
     21.2.(a)(i) above, the "worth at the time of award" shall be computed by
     allowing interest at the Interest Rate set forth in Section 30.5 of this
     Lease.  As used in Section 21.2(a)(ii) above, the "worth at the time of
     award" shall be computed by discounting such amount at the discount rate of
     the Federal Reserve Bank of Chicago at the time of award plus 1%.

           (b) Landlord may terminate the right of Tenant to possession of the
     Premises without terminating this Lease by giving notice to Tenant that
     Tenant's right of possession shall end on the date stated in such notice,
     whereupon the right of Tenant to possession of the Premises or any part
     thereof shall cease on the date stated in such notice but Tenant's
     obligations under this Lease shall continue in full force and effect.

           (c) Landlord may enforce the provisions of this Lease and may enforce
     and protect the rights of Landlord hereunder by a suit or suits in equity
     or at law for the specific performance of any covenant or agreement
     contained herein, or for the enforcement of any other appropriate legal or
     equitable remedy, including injunctive relief and recovery of all moneys
     due or to become due from Tenant under any of the provisions of this Lease.

                                       41


           (d) If Landlord exercises either of the remedies provided for in
     Sections 21.2(a) or 21.2(b), Tenant shall surrender possession and vacate
     the Premises immediately and deliver possession thereof to Landlord, and
     Landlord may then, or at any time thereafter, re-enter and take complete
     and peaceful possession of the Premises, full and complete license so to do
     being granted to Landlord, and Landlord may remove all occupants and
     property therefrom, using such force as may be necessary, without being
     deemed in any manner guilty of trespass, eviction or forcible entry and
     detainer and without relinquishing Landlord's right to Rent or any other
     right given to Landlord hereunder or by operation of law.

           (e) If Landlord terminates the right of Tenant to possession of the
     Premises without terminating this Lease, such termination of possession
     shall not release Tenant, in whole or in part, from Tenant's obligation to
     pay the Rent due hereunder for the full stated Lease Term.  At Landlord's
     option, the amounts described in clauses (i) through (v) of Section 21.2(a)
     shall at once mature and be immediately due and payable by Tenant to
     Landlord, together with any other amounts then due hereunder, and Landlord
     shall have the right to immediate recovery of all such amounts.
     Alternatively, at Landlord's option, Landlord shall have the right, from
     time to time, to recover from Tenant, and Tenant shall remain liable for,
     all Monthly Base Rent and Tenant's Share of Direct Expenses and any other
     sums then due under this Lease and thereafter accruing as they become due
     under this Lease during the period from the date of such notice of
     termination of possession to the end of the Lease Term.  Landlord may file
     suit from time to time to recover any such sums and no suit or recovery by
     Landlord of any such sums or portion thereof shall be a defense to any
     subsequent suit brought for any other sums due under this Lease.

           (f) In the event Landlord terminates the right of Tenant to
     possession of the Premises without terminating this Lease as aforesaid,
     Landlord shall use reasonable efforts to relet the Premises or any part
     thereof for the account of Tenant for such rent, for such time (which may
     be for a term extending beyond the Lease Term) and upon such terms as
     Landlord in Landlord's sole discretion shall determine; provided, if other
     vacant space then exists in the Building, Landlord may endeavor to lease
     such other space to prospective tenants rather than the Premises. Landlord
     shall not be required to accept any tenant offered by Tenant or to observe
     any instructions given by Tenant relative to such reletting. Also, in any
     such event, Landlord may make repairs, alterations and reasonably necessary
     additions in or to the Premises and redecorate the same to the extent
     reasonably deemed by Landlord necessary or desirable, and, in connection
     therewith, change the locks to the Premises, and Tenant shall upon demand
     pay the cost thereof together with Landlord's expenses of reletting.
     Landlord may collect the rents from any such reletting and apply the same
     first to the payment of the expenses of re-entry, redecoration, repair and
     alterations and the expense of reletting (including without limitation
     brokers' commissions and attorneys' fees) and second to the

                                       42


     payment of Rent herein provided to be paid by Tenant. Any excess or residue
     shall operate only as an offsetting credit against the amount of Rent as
     the same theretofore became or thereafter becomes due and payable
     hereunder, but the use of such offsetting credit to reduce the amount of
     Rent due Landlord, if any, shall not be deemed to give Tenant any right,
     title or interest in or to such excess or residue and any such excess or
     residue shall belong solely to Landlord. No such re-entry or repossession,
     repairs, alterations and additions, or reletting shall be construed as an
     eviction or ouster of Tenant, an election on Landlord's part to terminate
     this Lease or an acceptance of a surrender of this Lease, unless a written
     notice of such intention be given to Tenant, or shall operate to release
     Tenant in whole or in part from any of Tenant's obligations hereunder.
     Landlord may, at any time and from time to time, sue and recover judgment
     for any deficiencies remaining after the application of the proceeds of any
     such reletting.

     21.3  Efforts to Relet.  For the purposes of this Section 21, Tenant's
           ----------------
right to possession shall not be deemed to have been terminated by efforts of
Landlord to relet the Premises, by its acts of maintenance or preservation with
respect to the Premises, or by appointment of a receiver to protect Landlord's
interests hereunder.  The foregoing enumeration is not exhaustive, but merely
illustrative of acts which may be performed by Landlord without terminating
Tenant's right to possession.

     21.4  Sublessees of Tenant.  Whether or not Landlord elects to terminate
           --------------------
this Lease on account of any Default by Tenant, as set forth in this Section 21,
Landlord shall have the right to terminate any and all subleases, licenses,
concessions or other consensual arrangements for possession entered into by
Tenant and affecting the Premises or may, in Landlord's sole discretion, succeed
to Tenant's interest in such subleases, licenses, concessions or arrangements.
In the event of Landlord's election to succeed to Tenant's interest in any such
subleases, licenses, concessions or arrangements, Tenant shall, as of the date
of notice by Landlord of such election, have no further right to or interest in
the rent or other consideration receivable thereunder, provided that the net
proceeds therefrom are applied to Tenant's obligations hereunder.

     21.5  Removal of Property.  All property removed from the Premises by
           -------------------
Landlord pursuant to any provisions of this Lease or of law shall be handled,
removed or stored by Landlord at the cost, expense and risk of Tenant, and
Landlord shall in no event be responsible for the value, preservation or
safekeeping thereof.  Tenant shall pay Landlord upon demand for all expenses
incurred by Landlord in such removal and storage.

     21.6  Tenant's Payment of Landlord's Costs.  Tenant shall pay all costs,
           ------------------------------------
charges and expenses, including court costs and reasonable attorneys' fees
incurred by Landlord in enforcing Tenant's obligations under this Lease, in the
exercise by Landlord of any of its remedies in the event of a Default, in any
litigation, negotiation or transactions in which Tenant causes Landlord, without
Landlord's fault, to become involved or concerned, or in consideration of any
request for approval of or consent to any action by Tenant which is

                                       43


prohibited by this Lease or which may be done only with Landlord's approval or
consent (including, without limitation, any proposed Transfer pursuant to
Article 20), whether or not such approval or consent is given.

     21.7  Remedies Cumulative.  All of Landlord's rights and remedies under
           -------------------
this Lease shall be cumulative with and in addition to any and all rights and
remedies which Landlord may have at law or in equity.  Any specific remedy
provided for in any provision of this Lease shall not preclude the concurrent or
consecutive exercise of a remedy provided for in any other provision hereof.

     21.8  Additional Restrictions.  With respect to provisions of 735 ILCS 5/9-
           -----------------------
213.1 (or any successor provision thereto) which requires that a landlord take
reasonable measures to mitigate the damages recoverable against a defaulting
tenant, Tenant agrees that Landlord shall have no obligation to relet the Leased
Premises (i) before Landlord leases other vacant space in the Building, or (ii)
to any potential tenant who Landlord could reasonably reject as a transferee,
pursuant to Section 20.1 above.

22.  COUNTERCLAIMS
     -------------

     Tenant hereby waives any right to plead any counterclaim, offset or
affirmative defense in any action or proceedings brought by Landlord against
Tenant pursuant to the unlawful detainer laws of the State of Illinois or
otherwise, for the recovery of possession based upon the non-payment of Rent or
any other Default.  This shall not, however, be construed as a waiver of
Tenant's right to assert any claim in a separate action brought by Tenant
against Landlord.  Tenant agrees to pay all Rent without offset or reduction of
any kind whatsoever.  Tenant waives trial by jury in any action brought by
Landlord under or in respect of this Lease.  So long as Tenant is in default
under this Lease or any event or omission has occurred which, but for the giving
of notice or the passage of time, or both, would result in a default by Tenant
under the terms of this Lease, Landlord shall not be in default under the terms
of this Lease it fails to perform its obligations hereunder.

23.  HOLDING OVER
     ------------

     If Tenant retains possession of the Premises or any part thereof after the
expiration or termination of the Lease Term or Tenant's right to possession of
the Premises, Tenant shall pay rent during such holding over at 150% of the rate
in effect immediately preceding such holding over computed on a monthly  basis
for each month or partial month that Tenant remains in possession.  Tenant shall
also pay, indemnify and defend Landlord from and against all claims and damages,
consequential as well as direct, sustained by reason of Tenant's holding over.
The provisions of this Section do not waive Landlord's right of re-entry or
right to regain possession by actions at law or in equity or any other rights
hereunder, and any receipt of payment by Landlord shall not be deemed a consent
by Landlord to Tenant's remaining in possession or be construed as creating or
renewing any lease or right of tenancy between Landlord and Tenant.

                                       44


24.  SUBORDINATION AND ATTORNMENT
     ----------------------------

     Landlord and Tenant agree that this Lease be and hereby is made subject and
subordinate at all times to all ground and underlying leases and to all
mortgages in any amounts, and all advances thereon which may now or hereafter
affect the Building and to all renewals, modifications, consolidations,
participations, replacements and extensions thereof.  The term "mortgage" as
used herein shall be deemed to include a mortgage, bond, trust indenture, deed
of trust, deed to secure debt or other similar security instrument.  The
aforesaid provisions shall be self-operative and no further instrument of
subordination shall be required to effectuate any such subordination.  In the
event Landlord or the existing or future lessor under any such ground or
underlying lease or the existing or future holder of any such mortgage (each
existing or future holder of any such mortgage, shall sometimes be referred to
in this Lease individually, as the "Mortgagee" and collectively as the
"Mortgagee") desires confirmation of such subordination, Tenant shall execute
promptly and without charge therefor any certificate that may be requested.
Such certificate shall also contain, at the election of the Mortgagee or lessor,
an agreement whereby Tenant will attorn to said Mortgagee or lessor as Landlord
in the event of a foreclosure of such mortgage or termination of such ground or
underlying lease, or attorn to any party taking title through such mortgage or
lease in such event.  Notwithstanding the provisions hereof, should any lessor
or Mortgagee require that this Lease be prior rather than subordinate to its
mortgage or lease, or require that Tenant attorn to such Mortgagee or lessor as
Landlord in the event of a foreclosure of such mortgage or termination of such
ground or underlying lease, or to any party taking title through such mortgage
or lease in such event, then this Lease shall become prior and superior to such
mortgage or lease, as the case may be, or Tenant shall so attorn, upon written
notice to that effect to Tenant from such lessor or Mortgagee.  The aforesaid
superiority of this Lease to any mortgage or lease, and the attornment by Tenant
to such lessor or Mortgagee, shall be self-operative upon the giving of such
notice and no further documentation other than such written notice shall be
required to effectuate such superiority or attornment.  In the event Landlord or
such lessor or Mortgagee desires confirmation of such superiority or attornment,
Tenant shall, promptly upon request therefor by Landlord or such lessor or
Mortgagee, and without charge therefor, execute a document acknowledging such
priority or attornment obligation to the lessor or Mortgagee (or any party
acquiring title through such mortgage) as Landlord in the event of foreclosure
of such mortgage or deed in lieu thereof or termination of lease.  Tenant hereby
constitutes and appoints Landlord as Tenant's attorney-in-fact to execute any
such certificates or documents for and on behalf of Tenant if Tenant shall fail
to do so within ten days after demand.  The foregoing appointment of Landlord as
Tenant's attorney-in-fact is coupled with an interest and is irrevocable.

     If any mortgage is foreclosed, or Landlord's interest under this Lease is
conveyed or transferred in lieu of foreclosure, or if any ground lease is
terminated (i) no person or entity which as the result of any of the foregoing
has succeeded to the interest of Landlord under this Lease (a "Successor") shall
be bound to recognize any prepayment by more

                                       45


than 30 days of Base Rent or Additional Rent; and (ii) no Successor shall have
any liability for any security deposit paid to Landlord by Tenant hereunder,
unless such security deposit has actually been received by such Successor.
Further, Tenant agrees that in the event of any act or omission by Landlord
hereunder which could give Tenant the right to terminate this Lease or to claim
a partial or total eviction, Tenant shall not exercise any such right until it
has notified in writing the Successor (provided Tenant has theretofore received
written notice of such Successor) and such Successor shall have failed to
commence the curing of such act or omission within 30 days after such notice and
to diligently pursue the cure thereof until completed.

25.  ESTOPPEL CERTIFICATE
     --------------------

     Tenant agrees that from time to time, upon not less than seven (7) business
days' prior written request by Landlord or any Mortgagee or ground or underlying
lessor of the Building, Tenant will, and Tenant will cause any subtenant,
licensee, concessionaire or other occupant of the Premises to, promptly
complete, execute and deliver to Landlord, such Mortgagee or lessor or any party
or parties designated by Landlord, as applicable, a statement in writing
certifying: (i) that this Lease is unmodified and in full force and effect (or
if there have been modifications that the same are in full force and effect as
modified and identifying the modifications); (ii) the dates to which the Rent
and other charges have been paid; (iii) that the Premises have been
unconditionally accepted by the Tenant (or if not, stating with particularity
the reasons why the Premises have not been unconditionally accepted); (iv) the
amount of any Security Deposit held hereunder; (v) that, so far as the party
making the certificate knows, Landlord is not in default under any provisions of
this Lease, if such is the case, and if not, identifying all defaults with
particularity; and (vi) any other matter reasonably requested by Landlord. Any
purchaser, Mortgagee or ground or underlying lessor of the Building shall be
entitled to rely on said statement. Failure to give such a statement within
seven days after said written request shall be conclusive evidence, upon which
Landlord and any such purchaser, Mortgagee or lessor shall be entitled to rely,
that this Lease is in full force and effect and Landlord is not in default and
Tenant shall be estopped from asserting against Landlord or any such purchaser,
Mortgagee or lessor any defaults of Landlord existing at that time but Tenant
shall not thereby be relieved of the affirmative obligation to give such
statement.

26.  INTENTIONALLY OMITTED
     ---------------------

27.  NOTICES AND DEMANDS
     -------------------

     27.1  Notices.  All notices, demands, approvals, consents, requests for
           -------
approval or consent or other communications in this Lease provided to be given,
made or sent by either party hereto to the other ("Notice") shall be in writing
and shall be deemed to have been fully given, made or sent when made by personal
service, when received if sent by facsimile transmission, one business day after
deposit with a national overnight courier

                                       46


service or two business days after deposit in the United States mail certified
or registered and postage prepaid and properly addressed as follows:

     To Landlord:     Landlord's Management Agent at the address set forth in
                      Section 1.1.2 of the Summary.

     To Tenant:   (i) To the address set forth in Section 1.1.3 of the Summary.

The address to which any Notice should be given, made or sent to either party
may be changed by written notice given by such party as above provided.

     27.2  Notice by Landlord's Management Agent or Attorneys.  Any notice,
           --------------------------------------------------
demand, request or consent to be made by or required of Landlord, may be made
and given by Landlord's Management Agent or its attorneys with the same force
and effect as if made and given by Landlord.

28.  CONSTRUCTION OF LEASE
     ---------------------

     28.1  Construction of Lease.  The language in all parts of this Lease shall
           ---------------------
in all cases be construed as a whole according to its fair meaning and neither
strictly for nor against either Landlord or Tenant.  Section and subsection
headings in this Lease are for convenience only and are not to be construed as
part of this Lease or in any way defining, limiting, amplifying, construing, or
describing the provisions hereof. Time is of the essence of this Lease and every
term, covenant and condition hereof. The words "Landlord" and "Tenant," as
herein used, shall include the plural as well as the singular. The neuter gender
includes the masculine and feminine. In the event there is more than one person
or entity which executes this Lease as Tenant, the obligations to be performed
and liability of all such persons and entities shall be joint and several.
Landlord and Tenant agree that in the event any term, covenant or condition
herein contained (other than with respect to the payment of Rent) is held to be
invalid or void by any court of competent jurisdiction, the invalidity of any
such term, covenant or condition shall in no way affect any other term, covenant
or condition herein contained.

     28.2  Entire Agreement; Modification.  This Lease contains and embodies the
           ------------------------------
entire agreement of the parties hereto, and no representation, inducement or
agreement, oral or otherwise, not contained in this Lease shall be of any force
or effect. This Lease may not be modified in whole or in part in any manner
other than by an instrument in writing duly signed by both parties hereto.

     28.3  Approvals.  Whenever in this Lease any consent or approval with
           ---------
respect to any matter is required to be obtained from either Landlord or Tenant
and such provision requires that such consent or approval should not be
unreasonably withheld, delayed, and/or conditioned, it is the intent of Landlord
and Tenant that, in the giving or withholding of any such consent or approval,
the determination by the party from whom such consent

                                       47


or approval is required shall be governed by standards of "commercial
reasonableness" with due regard to any other factors, standards, or limitation
otherwise expressed herein with respect to the subject matter or the giving or
withholding of any such consent or approval. In the event of any dispute as to
whether a consent or approval was unreasonably withheld, delayed and/or
conditioned, the sole remedy of the party requesting the consent or approval
shall be to commence an action for a declaratory judgment; it being understood
and agreed that any claim for monetary damages for unreasonably withholding
and/or conditioning any consent or approval is hereby unconditionally and
irrevocably waived.

29.  REAL ESTATE BROKERS
     -------------------

     Tenant represents and warrants unto Landlord that Tenant has directly dealt
with and only with Landlord's Management Agent and the Leasing Broker, if any,
identified in Section 1.1.13 of the Summary as broker in connection with this
Lease, and agrees to indemnify and hold harmless Landlord from and against any
and all claims or demands, damages, liabilities and expenses of any type or
nature whatsoever arising by reason of the incorrectness or breach of the
aforesaid representation or warranty.  Landlord shall pay Landlord's Management
Agent and the Leasing Broker for commissions arising out of the execution and
delivery of this Lease pursuant to separate agreement.

30.  MISCELLANEOUS
     -------------

     30.1  Binding Effect.  Subject to the provisions of Sections 19 and 20
           --------------
hereof, all terms, covenants and conditions of this Lease shall be binding upon
and inure to the benefit of and shall apply to the respective heirs, executors,
administrators, successors, assigns and legal representatives of Landlord and
Tenant.

     30.2  Execution and Delivery.  The execution of this Lease by Tenant and
           ----------------------
delivery of the same to Landlord or Landlord's Management Agent does not
constitute a reservation of or option to lease the Premises or an agreement by
Landlord to enter into a lease, and this Lease shall become effective only if
and when Landlord executes and delivers a counterpart hereof to Tenant;
provided, however, the execution and delivery by Tenant of this Lease to
Landlord or Landlord's Management Agent shall constitute an irrevocable offer by
Tenant to lease the Premises on the terms and conditions herein contained, which
offer may not be withdrawn or revoked for 10 days after such execution and
delivery. If Tenant is a corporation, it shall deliver to Landlord following a
request therefor, certified resolutions of Tenant's directors authorizing
execution and delivery of this Lease and the performance by Tenant of its
obligations hereunder and such other evidence of authority for execution and
performance as Landlord shall reasonably require. If Tenant is a partnership or
limited liability company, it shall deliver to Landlord concurrently with the
delivery to Landlord of an executed Lease, a certified copy of its partnership
agreement or operating agreement, as the case may be, and such other evidence of
authority for

                                       48


execution and performance as Landlord shall reasonably require. Tenant shall not
record this Lease or any memorandum or other evidence hereof.

     30.3  Default Under Other Lease.  If the term of any lease (other than this
           -------------------------
Lease) made by Tenant for any demised premises in the Building shall be
terminated or terminable after the making of this Lease, because of any default
by Tenant under such other lease, such fact shall empower Landlord, at
Landlord's sole option, to declare this Lease to be in default by Tenant by
written notice to Tenant.

     30.4  Applicable Law.  This Lease shall be governed by and construed in
           --------------
accordance with the laws of the State of Illinois.

     30.5  Late Charges.  At the option of Landlord, Landlord may impose a late
           ------------
payment fee equal to 5% of the amount due if any payment of Rent is paid more
than five days after its due date.  In addition, any amount due hereunder shall,
if not paid when due, bear interest after the due date thereof, at the annual
rate (the "Interest Rate") equal to the greater of (a) 4% above the prime rate
as announced by LaSalle National Bank, from time to time, or if the use of the
prime rate is discontinued by LaSalle National Bank, such other rate as may
thereafter be announced from time to time by LaSalle National Bank, or any other
major bank selected by Landlord as a measure of the cost to its borrowers of
short-term commercial loans, until said past due amount shall be paid by Tenant
to Landlord or, (b) 18%, but in no event with respect to (a) and (b) greater
than the maximum rate permitted by law.  All amounts due under this Section 30.5
shall be deemed Additional Rent under this Lease.

     30.6  Nonwaiver of Defaults.  No waiver of any provision of this Lease
           ---------------------
shall be implied by any failure of Landlord to enforce any remedy on account of
the violation of such provision, even if such violation be continued or repeated
subsequently, and no express waiver shall affect any provision other than the
one specified in such waiver and in that event only for the time and in the
manner specifically stated. No receipt of monies by Landlord from Tenant after
the termination of this Lease will in any way alter the length of the Lease Term
or Tenant's right of possession hereunder or, after the giving of any notice,
shall reinstate, continue or extend the Lease Term or affect any notice given
Tenant prior to the receipt of such monies, it being agreed that after the
service of notice or the commencement of a suit or after final judgment for
possession of the Premises, Landlord may receive and collect any Rent due, and
the payment of Rent shall not waive or affect said notice, suit or judgment, nor
shall any such payment be deemed to be other than on account of the amount due,
nor shall the acceptance of Rent be deemed a waiver of any breach by Tenant of
any term, covenant or condition of this Lease. No endorsement or statement on
any check or any letter accompanying any check or payment of Rent shall be
deemed an accord and satisfaction. Landlord may accept any such check or payment
without prejudice to Landlord's right to recover the balance due of any
installment or payment of Rent or pursue any other remedies available to
Landlord with respect to any

                                       49


existing Defaults. None of the terms, covenants or conditions of this Lease can
be waived by either Landlord or Tenant except by appropriate written instrument.

     30.7  Force Majeure.  Either Tenant or Landlord shall not be deemed in
           -------------
default with respect to the failure to perform any of the terms, covenants and
conditions of this Lease on its part to be performed, if such failure is due in
whole or in part to any strike, lockout, labor dispute (whether legal or
illegal), civil disorder, inability to procure materials, failure of power,
restrictive governmental laws and regulations, riots, insurrections, war, fuel
shortages, accidents, casualties, Acts of God, acts caused directly or
indirectly by the other party (or its agents, employees, contractors, guests or
invitees), acts of other tenants or occupants of the Property or any other cause
beyond the reasonable control of the party obligated to perform. Notwithstanding
anything herein to the contrary, Tenant shall not be entitled to any extension
of time due to the unavailability of funds for any reason. In such event, the
time for performance shall be extended by an amount of time equal to the period
of the delay so caused.

     30.8  Landlord's Right to Perform Tenant's Duties.  If Tenant fails timely
           -------------------------------------------
to perform any of its duties under this Lease, Landlord shall have the right
(but not the obligation), after the expiration of any grace period specifically
provided by this Lease (unless expressly provided to the contrary elsewhere in
this Lease), to perform such duty on behalf and at the expense of Tenant without
further notice to Tenant, and all sums expended or expenses incurred by Landlord
in performing such duty shall be deemed to be Rent under this Lease and shall be
due and payable to Landlord upon demand by Landlord.

     30.9  Lease Tax.  If any governmental entity or authority has imposed or
           ---------
hereafter imposes a tax or assessment upon or against any of the rentals or
other charges payable by Tenant to Landlord hereunder (whether such tax takes
the form of a lease tax, sales tax or other tax), Tenant shall be responsible
for the timely payment thereof. Unless Landlord and Tenant otherwise agree in
writing with respect to the payment thereof, Tenant shall pay the applicable tax
to Landlord together with each payment by Tenant to Landlord of Rent due under
this Lease.

     30.10 Liens.  Without limitation of the provisions of Sections 9.1 and 9.2
           -----
of this Lease, Tenant agrees not to suffer or permit any lien of any mechanic or
materialman to be placed or filed against the Premises, the Building or the
Property. In case any such lien shall be filed, Tenant shall satisfy and release
such lien of record within five days after receipt of notice thereof from
Landlord or, if earlier, within five days after Tenant has actual knowledge or
notice of such lien filing. If Tenant shall fail to have such lien immediately
satisfied and released of record, Landlord may, on behalf of Tenant, without
being responsible for making any investigation as to the validity of such lien
and without limiting or affecting any other remedies Landlord may have, pay the
same and Tenant shall pay Landlord on demand the amount so paid by Landlord.
Notwithstanding the foregoing, Tenant shall have the right to contest any such
lien claim diligently and in good faith, and during such contest shall not be
obligated to pay such lien claim, provided that Tenant is

                                       50


not in breach of any of its obligations under this Lease and Tenant, at its sole
cost and expense, provides to Landlord, through Landlord's title insurer, a
title insurance endorsement in form and substance acceptable to Landlord
affirmatively insuring against any loss relating to such claim for the benefit
of Landlord and each of the Mortgagees and ground or underlying lessors of the
Building or, at its option, Tenant shall provide Landlord with a bond from a
company satisfactory to Landlord in form, substance and amount satisfactory to
Landlord, insuring against loss arising from the existence or attempted
enforcement of such lien. Notwithstanding any such contest or title insurance,
Tenant shall pay any such claim in full within five days following the entry of
an unstayed judgment or order of sale.

     30.11  Modification of Lease.  Should any current or prospective Mortgagee
            ---------------------
or ground lessor for the Building require a modification or modifications of
this Lease, which modification or modifications will not cause an increased cost
or expense to Tenant or in any other way materially and adversely change the
rights and obligations of Tenant hereunder, then and in such event, Tenant
agrees that this Lease may be so modified and agrees to execute whatever
documents are required therefor and deliver the same to Landlord within ten days
following the request therefor. Should Landlord or any such current or
prospective Mortgagee or ground lessor require execution of a short form of
Lease for recording, containing, among other customary provisions, the names of
the parties, a description of the Premises and the Lease Term, Tenant agrees to
execute such short form of Lease and to deliver the same to Landlord within ten
days following the request therefor.

     30.12  Relationship of Parties.  Nothing contained in this Lease shall be
            -----------------------
deemed or construed by the parties hereto or by any third party to create the
relationship of principal and agent, partnership, joint venturer or any
association between Landlord and Tenant, it being expressly understood and
agreed that neither the method of computation of Rent nor any act of the parties
hereto shall be deemed to create any relationship between Landlord and Tenant
other than the relationship of landlord and tenant.

     30.13  Application of Payments.  Landlord shall have the right to apply
            -----------------------
payments received from Tenant pursuant to this Lease, regardless of Tenant's
designation of such payments, to satisfy any obligations of Tenant hereunder, in
such order and amounts as Landlord, in its sole discretion, may elect.

     30.14  Right to Lease.  Landlord reserves the absolute right to effect such
            --------------
other tenancies in the Building and Property as Landlord in the exercise of its
sole business judgment shall determine to best promote the interests of the
Building and Property. Tenant does not rely on the fact, nor does Landlord
represent, that any specific tenant or type or number of tenants shall, during
the Lease Term, occupy any space in the Building or Property.

                                       51


     30.15  Waiver of Jury Trial; Attorneys' Fees.  If either party commences
            -------------------------------------
litigation against the other for the specific performance of this Lease, for
damages for the breach hereof or otherwise for enforcement of any remedy
hereunder, the parties hereto agree to and hereby do waive any right to a trial
by jury and, in the event of any such commencement of litigation, the prevailing
party shall be entitled to recover from the other party such costs and
reasonable attorneys' fees as may have been incurred, including any and all
costs incurred in enforcing, perfecting and executing such judgment.

     30.16  Independent Covenants.  This Lease shall be construed as though the
            ---------------------
covenants herein between Landlord and Tenant are independent and not dependent
and Tenant hereby expressly waives the benefit of any statute to the contrary
and agrees that if Landlord fails to perform its obligations set forth herein,
Tenant shall not be entitled to make any repairs or perform any acts hereunder
at Landlord's expense or to any setoff of the Rent or other amounts owing
hereunder against Landlord; provided, however, that the foregoing shall in no
way impair the right of Tenant to commence a separate action against Landlord
for any violation by Landlord of the provisions hereof so long as notice is
first given to Landlord and any Mortgagee or ground lessor, of whose address
Tenant has theretofore been notified, and a reasonable opportunity is granted to
Landlord and such Mortgagee or ground lessor to correct such violations.

     30.17  Transportation Management.  Tenant shall fully comply with all
            -------------------------
present or future programs intended to manage parking, transportation or traffic
in and around the Building and Property, to the extent that any such failure to
comply by Tenant could result in Landlord or the Building being in violation of
any law, rule, order, regulation or ordinance of any kind, or in any penalty,
fine or assessment being levied against the Building, Landlord or any other
tenant. In connection therewith, Tenant shall take responsible action for the
transportation planning and management of all employees located at the Premises
by working directly with Landlord, any governmental transportation management
organization or any other transportation-related committees or entities. Such
programs may include, without limitation: (a) restrictions on the number of
peak-hour vehicle trips generated by Tenant; (b) increased vehicle occupancy,
(c) implementation of an in-house ridesharing program and an employee
transportation coordinator, (d) working with employees and any Building or area-
wide ridesharing program manager, (e) instituting employer-sponsored incentives
(financial or in-kind) to encourage employees to rideshare; and (f) utilizing
flexible work shifts for employees.

     30.18  No Air Rights.  No rights to any view or to light or air over any
            -------------
property, whether belonging to Landlord or any other person, are granted to
Tenant under this Lease.

     30.19  Partial Invalidity.  If any term, provision or condition contained
            ------------------
in this Lease shall, to any extent, be invalid or unenforceable, the remainder
of this Lease (or the application of such term, provision or condition to
persons or circumstances other than those in respect of which it is invalid or
unenforceable) shall not be affected thereby, and

                                       52


each and every other term, provision and condition of this Lease shall be valid
and enforceable to the fullest extent permitted by law; provided, however, that
if any provision of this Lease relating to payment of Base Rent or Additional
Rent is invalid or unenforceable, Landlord shall have the right to terminate
this Lease.

     30.20  Authorized Signatory.  If Tenant is a corporation or partnership,
            --------------------
Tenant represents and warrants that the person executing this Lease is a duly
authorized signatory for and on behalf of the Tenant.

     30.21  Financial Information.  Tenant represents and warrants that all
            ---------------------
financial information heretofore and hereafter delivered to Landlord is true and
correct and that no material misstatements or omissions exist therein.

31.  LANDLORD EXCULPATION
     --------------------

     It is expressly understood and agreed that notwithstanding anything in this
Lease to the contrary, and notwithstanding any applicable law to the contrary,
the liability of Landlord hereunder and any recourse by Tenant against Landlord
shall be limited solely and exclusively to the interest of Landlord in and to
the Property. Neither Landlord, nor any of its beneficiaries or their respective
constituent partners, shall have any personal liability hereunder, and Tenant
hereby expressly waives and releases such personal liability on behalf of itself
and all persons claiming by, through or under Tenant.

     In addition to the foregoing, and not by way of limitation of the
generality of the exculpation set forth in the preceding paragraph, this Lease
is executed by LaSalle National Bank, not personally, but solely as aforesaid in
the exercise of the power and authority conferred upon and vested in it as
Trustee, and under the express direction of the beneficiaries of the said Trust.

     It is expressly understood and agreed that nothing herein shall be
construed as creating any liability whatsoever against said Trustee personally,
and in particular, without 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
said Tenant, and by every person now or hereafter claiming any right or security
hereunder; and that so far as the said Trustee is concerned the owner of any,
indebtedness or liability accruing hereunder, shall look solely to the assets of
said Trust and the proceeds thereof for the payment thereof.

     It is further understood and agreed that the said Trustee merely holds
naked title to the Property herein described and has no control over, and under
this Lease assumes no responsibility for:

                                       53


          (a)  Management or control of the Property;

          (b)  Upkeep, inspection, maintenance or repair of the Property;

          (c)  Collection of rents or the rental of space in the Property; or

          (d)  The conduct of any business which is carried on upon the
               Property.

     It is further understood that the foregoing exoneration clause shall apply
to any institutional land trustee which shall at any time be the Landlord
hereunder. Moreover, in the event this Lease is assigned to a Landlord which is
not an institutional land trustee, then said Landlord shall not be personally
liable to Tenant or any party claiming by, through or under Tenant for any
liabilities or obligations arising under or in respect of this Lease or the
Building, but rather Tenant and all such other parties shall look solely to the
Building for the enforcement thereof.

the cost of Tenant Work and shall be the sole responsibility of Landlord: (i)
any costs incurred due to the remediation of Hazardous Materials, where such
were not caused by Tenant, and (ii) any costs incurred to correct any non-
compliance with codes, laws, or statutes where such non-compliance existed prior

     2.3  Standard Tenant Improvement Package.  Landlord has established
          -----------------------------------
specifications (the "Specifications") for the Building standard components to be

the base building plans, and Tenant and Architect shall be solely responsible
for the same, and Landlord shall have no responsibility in connection therewith.
Landlord's review of the Construction Drawings as set forth in this Section 3,
and Landlord's supervision of the construction of the Tenant Improvements shall

other like matters. Accordingly, notwithstanding that any Construction Drawings
are reviewed or the construction of Tenant Improvements is supervised by
Landlord or its space planner, architect, engineers and consultants, and
notwithstanding any advice or assistance which may be rendered to Tenant by
Landlord or Landlord's space planner, architect, engineers, and consultants,
Landlord shall have no liability whatsoever in connection therewith and shall
not be responsible for any omissions or errors contained in the Construction
Drawings or for any defects in the construction of the Tenant Improvements;

necessary to allow Contractor to commence and fully complete the construction of
the Tenant Improvements (the "Permits"), and, in connection therewith, Tenant

Approved Construction Drawings may be made without the prior written consent of
Landlord, provided that Landlord may withhold its consent, in its sole
discretion, to any change in the Approved Construction Drawings if such change
would directly or indirectly delay the completion of the Premises or increase
the cost of the Tenant Improvements.

     3.5  Time Deadlines.  Tenant shall use its best, good faith, efforts and
          --------------
all due diligence to cooperate with the Architect, the Engineers, and Landlord

occurred on the date the Substantial Completion of the Premises would have
occurred if no Tenant Delay or Delays, as set forth above, had occurred.
