repossess the Subleased Premises and be entitled to recover forthwith, in
addition to any other sums owing to Sublessor from or damages caused by
Sublessee, as damages a sum of money equal to the worth, discounted at the rate
of the Prime Rate at the Chase Manhattan Bank, New York, in effect at the time
of Sublessor's termination, of the excess, if any, of the amount of Base Rent
and all other sums to be paid by Sublessee under this Sublease throughout the
balance of the Sublease Term in effect at the time of termination (as if not
terminated by Sublessor because of Sublessee's

                                       8

default) over the then fair market rental value of the Subleased Premises for
the same period. Should the fair market rental value of the Subleased Premises
for the balance of the Sublease Term exceed the value of the Basic Rent and
additional rent provided to be paid by Sublessee for the balance of the Sublease
Term, Sublessor shall have no obligation to pay to Sublessee the excess or any
part thereof.

All installments of Base Rent or Additional Rent not paid when due and payable
shall bear interest at the lesser of (a) the rate of ten percent (10%) or (b)
the maximum interest rate permitted by law, from the date due until paid. In
addition, Sublessee shall pay to Sublessor five percent (5%) of the overdue
amount as a late charge. Sublessor's acceptance of any late charge or interest
shall not constitute a waiver of Sublessee's default with respect to the overdue
amount nor prevent Sublessor from exercising any of the other rights and
remedies available to Sublessor under this Sublease or any law now or hereafter
in effect.

24.  Utilities and Services
     ----------------------

Sublessee shall be entitled to all of the services and rights to which Sublessor
is entitled under the Prime Lease. Sublessor shall take all reasonable steps
necessary to ensure that all utilities and services called for under the Prime
Lease are made available to Sublessee; provided, however, Sublessor shall have
no liability or responsibility should Prime Landlord not provide any of the
services required under the Prime Lease, and Sublessee's responsibility to pay
Base Rent under this Sublease shall not be affected in any way unless Sublessor
is excused from paying rent under the Prime Lease; and further provided,
however, that in the event of a breach of the Prime Lease by Prime Landlord
which would entitle Sublessor to terminate the Prime Lease, Sublessee shall be
entitled to terminate the Sublease. Sublessor shall cause the Subleased Premises
to be submetered for electricity at Sublessor's expense, and Sublessee shall pay
electricity costs directly to the utility company.

25.  Sublessee's Obligations and Sublessor's Right to Perform Sublessee's
     --------------------------------------------------------------------
     Obligations
     -----------

Subject to the terms of this Sublease, Sublessee, with respect to the Subleased
Premises, will duly and faithfully observe all the applicable terms and
restrictions and perform all the applicable obligations imposed on Sublessor as
tenant under the Prime Lease. Sublessor shall have the right (but not the
obligation) to take any and all applicable actions required to be taken by
Sublessee pursuant to the provisions hereof or the Prime Lease, but not timely
taken by Sublessee, which may be necessary to prevent a default under or to
assure complete compliance with the terms of this Sublease or the Prime Lease.
All costs and expenses reasonably incurred by Sublessor, including, but not
limited to, counsel fees, for any actions taken pursuant to this Article 25
shall be payable by Sublessee, as additional rent, within five (5) days after
delivery of a statement of any such costs to Sublessee.

26.  Not to Cause Default
     --------------------

Neither Sublessor nor Sublessee shall do or permit anything to be done which
would cause the Prime Lease to be terminated or forfeited by reason of any
right of termination or forfeiture reserved or vested in the Prime Landlord
under the Prime Lease, and each party shall indemnify and hold the other party
harmless from and against all claims of any kind whatsoever by reason of any
breach or default on the part of the indemnifying party by reason of which the
Prime Lease may be terminated or forfeited. Furthermore, in no event shall
Sublessee be liable to both Sublessor and the Prime Landlord for damages,
arising from the same breach, default or holdover, and Sublessor shall indemnify
and hold Sublessee harmless from and against any claims the Prime Landlord to
the extent the same have been paid by Sublessee to Sublessor. The indemnities in
this Section 26 shall be applicable to Sublessee's liabilities in the event of
an exercise by Prime Landlord of Prime Landlord's rights under Section 5(b) of
that certain Consent to Sublease Agreement by and among Sublessor, Sublessee and
Prime Landlord.

27.  Waiver
     ------

Failure of either party to insist upon the strict performance of any of the
terms or conditions herein shall not constitute a waiver of such party's rights
to thereafter enforce such terms and conditions.

28.  Arbitration
     -----------

All disputes and other matters in question between Sublessor and Sublessee shall
be decided by arbitration in accordance with the applicable rules of the
American Arbitration Association. The foregoing agreement to arbitrate shall be
enforceable under the prevailing arbitration law. The award rendered by the
arbitrators shall be final, and judgment may be entered upon it in accordance
with applicable law in any court having jurisdiction thereof. Arbitration shall
be the exclusive method of resolving disputes and other matters in question
between Sublessor and Sublessee, unless the parties shall otherwise agree in
writing.

30.  Brokers
     -------

Sublessee covenants, warrants, and represents that it has not dealt with any
broker in connection with this Sublease other than Julien J. Studley, Inc. (the
"Brokers"), and Sublessor agrees to pay the commission of the Broker in
accordance with a separate agreement. The Parties agree to indemnify and hold
each other harmless from any and all liability, damage, costs, expenses and fees
(including attorneys' fees) which either may incur or be required to pay as a
result of the other's dealings with any other broker.

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

This Sublease shall be governed by and construed in accordance with the laws of
the State of Illinois.

33.  Full Negotiation
     ----------------

This Sublease, although drafted by Sublessor, is the result of extensive
negotiations between Sublessor and Sublessee and their respective counsel and,
therefore, shall be interpreted and construed only by the contents hereof, and
there shall be no presumption or standard of construction in favor of or against
either Sublessor or Sublessee.

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

in writing executed by Sublessor and Sublessee.

35.  Partial Payment
     ---------------

No payment by Sublessee or receipt by Sublessor of a lesser amount than the
correct Base Rent due hereunder shall be deemed to be other than a payment on
account, nor shall any endorsement or statement on any check or letter
accompanying any check or payment be deemed to effect or evidence an accord and
satisfaction, and Sublessor may accept such check or payment without prejudice
to Sublessor's right to recover the balance or pursue any other remedy in this
Sublease or at law provided.

36.  Partial Invalidity
     ------------------

If any one of the provisions of this Sublease, or the application thereof to any
person or circumstance, shall, to any extent, be invalid or unenforceable, the
parties shall incorporate in this Sublease a lawful clause with similar and
equivalent economic consequences so that the respective rights and obligations
of the

                                       11
<PAGE>

parties shall be maintained. Further, the remainder of this Sublease, or the
application of such provision or provisions to persons or circumstances other
than those to whom or which it is held invalid or unenforceable, shall not be
affected thereby, and every provision of this Sublease shall be valid and
enforceable to the fullest extent permitted by law.

37.  No Offer
     --------

This Sublease is transmitted for examination only and does not constitute an
offer to lease. This Sublease shall not be binding on either Party in any way
unless and until it is duly executed and unconditionally delivered by both
Parties and the Prime Landlord.

and sealed as of the day and year first above written.
