the Adjustment Year in which such Adjustment Date falls shall be the annual
rate of rent for the immediately preceding Adjustment Year.

     C. Tenant shall pay the rent provided for in Section 4.01(B) above, to or

CONSTRUCTION STAGING AREA", being an area thirty-five (35) feet by one hundred
twenty (120) feet, adjacent to the Premises, for temporary storage and use of
construction materials and equipment during any time, from time to time, that
Lessee is constructing, installing, removing, repairing or replacing
improvements or Equipment upon or in the Premises as permitted by this
agreement, and during the time of clean-up operations after completion of any
such construction, installation, removal, repairs or replacements; provided,
however, that Lessee shall not place any buildings or structures on the area
covered by such Easement; and provided that Lessee shall repair and restore the
area covered by such Easement after any such construction, installation,
removal, repairs or replacements to at least as good a condition as when Lessee
first entered upon the area covered by such Easement; and provided further that
Lessee's use of such Easement shall not exceed sixty (60) days consecutively
during any twelve (12) month period; and provided further that Lessee shall
store such construction materials and equipment at Lessee's own risk.

The Easements shall remain in effect during the Term and any Extended Terms.
Lessor shall maintain, in at least its present condition and repair, the areas
covered by the Easements ("Easement Areas") throughout the Term and any
Extended Terms.  No additional rent or other consideration shall be payable by
reason of Lessor's grant of the Easements.

     B. (i)  Lessor represents that Lessee shall have free and unrestricted
access over Easement #1 for ingress and egress and passage of pedestrians,
vehicles and construction materials and equipment to and from the Premises
during the Term and any Extended Terms, twenty-four (24) hours each and every
day, seven (7) days per week, for the purpose of constructing, installing,
removing, repairing, replacing, maintaining and operating Lessee's improvements
and Equipment, and that Lessor shall not permit or suffer any interference with
such free and unrestricted access.  Notwithstanding anything to the contrary
contained herein, if Lessor's performance of its obligations hereunder is
delayed due to a "Cause" (as hereinafter defined), Lessor shall have such
additional time to perform its obligations as is equal to the period of delay
resulting from the Cause.

     (ii) Throughout the Term and any Extended Terms, Lessor shall provide snow
removal services, at least between the hours of 9:00 a.m. and 5:00 p.m., at
least on weekdays other than legal holidays, on concrete or asphalt paved
portions of Easement #1, as, when and where necessary to ensure that Lessee

an open public street, road or way.  Throughout the Term and any Extended
Terms, Lessor shall provide Lessee with a telephone number which, if called by
Lessee, will ring at a location that is staffed by Lessor or its agents or
employees at least between the hours of 9:00 a.m. and 5:00 p.m., at least on
weekdays other than legal holidays.  If Lessee calls such telephone number from
time to time and requests snow removal services from Lessor, Lessor will cause
such snow removal services to be provided so that the aforedescribed free and
unrestricted access will be restored within two (2) hours of the time of that
call.  Notwithstanding anything to the contrary contained herein, if Lessor's
performance of its snow removal obligations is delayed due to a "Cause" (as
hereinafter defined), Lessor shall have such additional time to perform its
snow removal obligations as is equal to the period of delay resulting from the
Cause.

     (iii) For purposes of this paragraph 4B, a "Cause" means any one or more
of the following: a strike, lockout or labor difficulty; explosion, sabotage,
accident, riot, or civil

<PAGE>   11



commotion; act of war; fire or other catastrophe; or any other cause beyond
Lessor's reasonable control; provided that a lack of funds on the part of
Lessor shall not be deemed to be a cause beyond Lessor's reasonable control.

     C. At Lessee's request from time to time, and without further payment or
consideration, Lessor shall grant and convey to the electric and/or telephone
utility companies serving or authorized to serve the Premises, by and using
such forms of instrument or easement agreement as are then being used by such
companies, perpetual easements to use the Easement Areas described in
subparagraph 4A (ii) hereof for the purposes set forth in said subparagraph 4A
(ii), on such terms and conditions as are customarily contained in such forms
of instrument or easement agreement as are then being used by such companies;
and Lessor shall take any and all actions acceptable to Lessor in its
reasonable discretion and execute, acknowledge and deliver any and all
documents (acceptable to Lessor in its reasonable discretion) requested by such
companies or Lessee in order to accomplish the foregoing.  Lessee shall
indemnify Lessor for any expense in connection with the foregoing.

     5. Lessor represents that Lessor owns good and marketable title in fee
simple to the Premises and the Easement Areas described in paragraph 4A hereof,
free and clear of all liens and encumbrances except as set forth on Exhibit C
attached hereto and made a part hereof, and Lessor acknowledges that Lessee is
relying upon the foregoing in entering into this agreement and in expending
monies in connection herewith.  Other than a mortgage on the Property, Lessor
shall not encumber or permit any encumbrances, liens or restrictions on the
title to the Premises or the Easement Areas other than those set forth on
Exhibit C hereto, except with the prior written approval of Lessee.  Lessor
may, at its option, subordinate this agreement and Lessee's interest hereunder
to any mortgage, deed of trust, prime lease, or other lien hereafter placed on
the Premises; provided that Lessor shall first obtain and deliver to Lessee
from any future mortgagee, trustee, fee owner, prime lessor or any person
seeking to have an interest in the Premises superior to this agreement, a
written non-disturbance agreement providing that (a) as long as Lessee attorns
to the mortgagee, trustee, fee owner, prime lessor or other person, its
successors and assigns, this agreement shall be recognized by the mortgagee,
trustee, fee owner. prime lessor or other person, and that all of the rights of
Lessee, including, without limitation, Lessee's options to extend the Term of
this agreement, shall remain in full force and effect during the Term and any
Extended Term, and (b) as long as Lessee attorns to the mortgagee, trustee, fee
owner, prime lessor or other person, its successors or assigns, and performs
all of Lessee's obligations hereunder, Lessee shall not be named or joined in
any action or proceeding to foreclose or terminate the interest of Lessor or
enforce any such mortgage, deed of trust, prime lease or fee owner's rights, or
the rights of such other person, brought or filed by any such person. in the
event of foreclosure or any enforcement of any such mortgage, deed of trust,
prime lease or fee owner's rights, or the rights of such other person, Lessee's
rights hereunder shall expressly survive, and this agreement shall in all
respects continue in full force and effect; provided that Lessee performs all
its obligations hereunder and attorns to the mortgagee, trustee, purchaser at
the foreclosure sale, prime lessor, fee owner or other person.  The
subordination of this agreement and Lessee's interest hereunder to any such
mortgage, trust deed, prime lease or other instrument is expressly conditional
upon Lessor obtaining and delivering to Lessee such non-disturbance agreement.
Provided such non-disturbance agreement is delivered to Lessee, Lessee agrees
to execute, if the same is required, any and all instruments in writing which
may be requested by Lessor to subordinate Lessee's rights under this agreement
to the lien of any such

<PAGE>   12



mortgage, deed of trust, prime lease or any other instrument, all as aforesaid.

     6. A. Lessee shall pay directly all charges for heat, light, power,
telephone and other utilities used in connection with the Premises during the
Term and any Extended Terms.  In connection with the foregoing, Lessee shall
also pay the cost of installation of any necessary separate meters.  If Lessee
shall fail to pay any such charges when due, Lessor may pay the same, and
Lessee shall repay Lessor for any amounts so advanced within fifteen (15) days
after receipt of Lessor's statement therefor.

     B. Lessee shall pay as additional rent during the Term and any Extended
Term any portion of the real estate taxes for the parcel of real estate owned
by Lessor of which the Premises are a part (which parcel is designated by
Permanent Tax Index Number 10-29-105-006-0000) directly attributable to
additional improvements included as part of the improvement portion of the
assessed valuation of said parcel for and by reason of improvements or
additions constructed or made by Lessee on the Premises; provided that Lessee
and its agents, in Lessee's name or in the name of Lessor, shall have the right
at Lessee's expense to contest the amount and validity, in whole or in part, of
any tax or portion thereof for which Lessee is responsible pursuant to the
terms hereof, by appropriate proceedings diligently conducted.  If any rebate
of such real estate taxes is made, the rebate shall be retained by or paid to
Lessee based on the proportion which the real estate taxes paid by Lessee bears
to the total amount of real estate taxes to which such rebate relates.  Lessor
shall promptly forward to Lessee copies of all applicable assessment notices
and tax bills and other matters relating to the real estate taxes to the end
that Lessee is not prejudiced in exercising the rights granted hereunder.

     C. Lessee shall pay all personal property taxes levied on the Equipment
installed by Lessee on the Premises.

     7. Lessee shall have the right at any time during the Term and any
Extended Terms, at their own expense, to construct or make upon or in the
Premises any improvements or additions of whatever kind or description
necessary or convenient to the use of the Premises in accordance with paragraph

remove any such improvements, additions and Equipment so constructed, made or
installed.  Upon completion of initial construction and installation of
improvements, additions and Equipment on the Premises, Lessee shall secure the
Promises by installing on the Premises at Lessee's expense a ten (10) foot tall
fence, or such smaller fence as may be the highest fence permitted under local
law.  Any and all improvements or additions so constructed or made, and any and
all Equipment so installed, upon or in the Premises, shall remain personal
property notwithstanding the fact that any or all of same may be affixed or
attached to the Premises, and, during the Term and any Extended Terms, and upon
expiration thereof, or the termination of this agreement, shall belong to and
be removable by Lessee.

     8. Lessee shall keep the Premises in good condition and repair in
accordance with applicable federal, state and municipal laws, and, at the
expiration of the Term and any Extended Terms, or such earlier date as this
agreement is terminated, Lessee will remove (to the ground level on the date
hereof) all above-ground improvements, additions and Equipment constructed,
made or installed by Lessee, will place the Premises in a reasonably level and
non-hazardous condition, and will otherwise yield up the Premises in at least
as good a condition as when the

<PAGE>   13



same were entered upon by Lessee, loss by casualty and ordinary wear and tear
excepted.

     9. Lessee and its agents may apply to the appropriate governmental
authorities and public utilities for any Approvals and easements required of or
deemed necessary or useful by Lessee for its use of the Premises, or in order
to construct or make improvements or additions, or to install Equipment, upon
or in the Premises.  Lessor shall join in any such applications as requested by
Lessee and shall cooperate fully with Lessee in connection with the foregoing
and, upon request of Lessee, shall take any and all actions and execute,
acknowledge and deliver any and all documents and instruments reasonably
requested by Lessee (including, without limitation, the grant of utility
easements), provided that none of the foregoing actions, documents or
instruments shall impose any liability on Lessor.  Lessee shall pay directly
any costs in connection with the foregoing.  Lessee shall pay all license,
permit and inspection fees required in connection with its use of the Premises
or the conduct of its business thereon.  Notwithstanding anything to the
contrary contained herein, Lessee shall not apply for any zoning change the
effect of which will interfere with the current use of the Property or make the
current use of the Property non-conforming under the applicable law, and no
aspect of any zoning change granted in connection with Lessee's initial
construction and installation of improvements, additions and/or Equipment upon
or in the Premises shall rely on any other portion of the Property to satisfy
zoning requirements applicable to the Premises.

1987:  Lessee shall have received the Approvals and easements referred to in
paragraphs 2, 4C and 9 hereof.  If by said date one or more of such events
shall not have occurred, then at Lessee's option, which shall be exercised, if
at all, on or before April 30, 1987, Lessee may waive such contingencies and
thereby continue this agreement in full force and effect, or Lessee may

Upon such termination by Lessee, this agreement, the Term and all of Lessee's
obligations contained herein shall forthwith terminate and end on the date
specified in such notice; provided that if Lessee terminates this agreement
pursuant to this paragraph 10, Lessor shall refund the Lump Sum Payment to
Lessee within ten (10) days after Lessee's notice of termination, but Lessor

Notwithstanding anything to the contrary contained herein, upon such
termination, Lessee shall indemnify Lessor for any liabilities arising prior to
such termination due to Lessee's acts or omissions on the Premises or the
Easement Areas.

     11. Lessee Shall indemnify and hold harmless Lessor, Lessor's
beneficiaries, any mortgagee of the Premises and/or the Easement Areas
("Mortgagee") and the Premises and the Easement Areas from and against all
liens or claims for lien for material or labor by reason of any work done
and/or material furnished Lessee in connection with the construction by Lessee
of any improvements or additions upon or in the Premises.  If any such lien or
claim for lien is filed against the Premises or the Easement Areas, or any part
thereof, by reason of the construction of any improvements or additions by
Lessee, Lessor shall give notice thereof to Lessee and demand that Lessee
remove such lien or claim for lien, and if the same is not removed within
thirty (30) days after Lessee receives such notice and demand, then (and only
then) Lessor may (unless within such thirty (30) day period Lessee furnishes to
Lessor a surety bond protecting Lessor against such lien), without inquiring
into the validity thereof, remove the same at its own expense, and Lessee shall
repay Lessor for any amounts so advanced within fifteen (15) days

<PAGE>   14



after receipt of Lessor's statement therefor.

     12. Lessee shall, at its own expense, during the Term and any Extended
Terms, insure Lessor, Lessor's beneficiaries from time to time, and any
Mortgagee whose existence has been made known to Lessee by a notice from

company or companies authorized to do business in the State of Illinois against
any liability which may be incurred by Lessor, Lessor's beneficiaries or any
such mortgagee on account of death, bodily injury or property damage which may
be sustained by any person or persons or their property who or which might at
any time be in or about the Premises.  Said policy or policies of insurance
shall provide coverage on an occurrence basis and shall be in limits of not
less than One Million Dollars ($1,000,000.00), in the event of either bodily
injury or death, or property damage, or both, as the result of any one accident
or occurrence.  Lessee shall deliver certificates therefor to Lessor upon
request.  The certificate shall contain a statement to the effect that should
said policy or policies be canceled prior to the expiration date therof, the
issuing company or companies will endeavor to mail thirty (30) days written
notice to the certificate holder.  In the event Lessee shall fail to procure
such public liability insurance or pay the premiums therefor or deliver said
certificates therefor to Lessor upon request, Lessor may procure such insurance
and pay the premiums therefor, and Lessee shall repay Lessor for any amounts so
advanced within fifteen (15) days after receipt of Lessor's statement therefor.
In addition, Lessee shall, at its own expense, obtain the following: (a)
automobile liability insurance in limits of not less than One Million Dollars
($1,000,000.00); (b) workman's compensation as required by Illinois law; and
(c) umbrella liability insurance in limits of not less than Four Million
Dollars.

     13. Lessee and Lessor shall each be responsible for maintaining insurance
covering their own property, whether or not located on the Premises.  Lessor
and Lessee each hereby waive any and all rights of recovery, claim, action, or
cause of action, each may have against the other, its agents, officers or
employees, on account of any loss or damage occasioned to Lessor or Lessee, as
the case may be, their respective property, the Premises or any improvements
thereon or therein, or any personal property of such party thereon or therein,
or the Easement Areas, by reason of fire, the elements or any other cause which
customarily is insured against under the terms of standard .all risk' property,
fire and extended coverage insurance policies, regardless of cause or origin,
including negligence of the other party hereto, its agents, officers or
employees.  Each party hereto, on behalf of its respective insurance companies
insuring its property against any such loss, does hereby waive any right of
subrogation that such companies may have against the other party hereto.  The
parties hereto covenant with each other that, to the extent such insurance
endorsement is available, they will each obtain, for the benefit of the other,
an explicit waiver of any such right of subrogation from its respective
insurance companies.

     14. Lessee may terminate this agreement by thirty (30) days' notice to
Lessor accompanied by a termination fee equal to the greater of (a) Five
Thousand Dollars ($5,000.00) and (b) an amount equal to three (3) months rent
at the then current rate, and upon such termination the Term and all
obligations of the Lessee contained herein shall forthwith terminate and end on
the date specified in such notice.  If Lessee terminates this agreement
pursuant to this paragraph 14, Lessor shall be entitled to retain all rent
theretofore paid by Lessee.  Notwithstanding anything to the contrary contained
herein, upon such termination, Lessee shall indemnify Lessor, Lessor's
beneficiaries and any Mortgagees for any liabilities arising prior to

<PAGE>   15



such termination due to the acts or omissions of Lessee and its agents and
employees on the Premises or the Easement Areas.

     15. Lessee shall have the right, without the consent of Lessor, to assign
this agreement and the Easements contained herein or sublet all or any part of
the Premises for any use permitted by paragraph 3 hereof.  In addition, Lessee
shall have the right, without the consent of Lessor, to assign or otherwise
transfer this agreement, the Easements contained herein, and each, every and
all of Lessee's rights, privileges and obligations hereunder, in consideration
of or as additional security for any financing or equipment leasing arrangement
into which Lessee may enter which may affect Lessee's interest hereunder, and
any such assignment or transfer shall not constitute a default under this
agreement.  Further, Lessee shall have the right to record, register or file
such evidence of any such assignment or transfer as may be required in
conjunction with any such financing or equipment leasing arrangement, and such
recording, registration or filing shall not constitute a default under this
agreement.  An assignment to a person, firm or corporation which, at the time
of such assignment, has a smaller net worth than Lessee then has shall not
release Lessee of its obligations under this lease, except an assignment to a
corporation into which or with which Lessee merges or consolidates.  Lessee
shall, within a reasonable time after any assignment, transfer or subletting,
notify Lessor of the name and address of the assignee, transferee or sublessee;
and Lessee shall, within a reasonable time after any assignment or transfer,
provide Lessor with a copy of an instrument whereby the assignee or transferee
has assumed Lessee's obligations under this agreement.

     16. Lessor, on behalf of itself and all persons, corporations and other
entities claiming by, through or under Lessor, covenants and agrees with Lessee
that as long as Lessee pays the rent herein reserved and performs all of
Lessee's obligations hereunder, subject only to the right of Midwesco, Inc., an
Illinois corporation, as Tenant of the Property under a certain lease dated
November 18, 1976 between said corporation as Tenant and Lessor hereunder as
Landlord, to concurrent use of the Easement Areas, Lessee shall have quiet and
peaceful enjoyment and possession of the Premises and the Easement Areas
throughout the Term and any Extended Terms, free from claims by any person,
corporation or other entity claiming by, through or under Lessor or any person,
corporation or other entity claiming under title paramount to Lessor, and shall
be entitled to exercise all of Lessee's rights hereunder (including, without
limitation, Lessee's options to extend the Term of this agreement) during the
Term and any Extended Terms.

     17. Lessee will, from time to time, upon ton (10) days' prior request by
Lessor, execute, acknowledge and deliver to Lessor a certificate of Lessee
stating that this agreement is unmodified and in full force and effect (or, if
there have been modifications, that this agreement is in full force and effect
as modified, and setting forth such modifications) and the dates to which rent
and additional rent have been paid, and either stating that to the knowledge of
Lessee no default exists hereunder or specifying each such default of which
Lessee has knowledge.  Lessor will, from time to time, upon ten (10) days'
prior request by Lessee, execute, acknowledge and deliver to Lessee a
certificate of Lessor stating that this agreement is unmodified and in full
force and effect (or, if there have been modifications, that this agreement is
in full force and effect as modified, and setting forth such modifications) and
the dates to which rent and additional rent have been paid, and either stating
that to the knowledge of Lessor no default exists hereunder or specifying each
such default of which Lessor has knowledge.  Any such certificate of Lessee or
Lessor may be relied upon by any person or entity.

<PAGE>   16


     18. A. If Lessee shall default in the payment of any installment of the
rent hereby reserved and any such default shall continue for a period of ten
(10) days after written notice thereof is received by Lessee, or if Lessee
shall default in the performance of any other obligation herein contained to be
performed by Lessee and any such default shall continue for a period of thirty
(30) days after written notice thereof is received by Lessee (provided,
however, that if the default reasonably cannot be cured within thirty (30)
days, said thirty (30) day period shall be extended for such additional time as
is reasonably necessary to cure the default), or if Lessee is adjudicated a
bankrupt or a trustee is appointed for Lessee after a petition for
reorganization or arrangement has been filed by or against Lessee under the
Bankruptcy Act of the united States, or a receiver is appointed for Lessee's
business or property (and the order of adjudication or for the appointment of a
trustee or receiver has not been vacated within sixty (60) days after the entry
thereof), then upon ten (10) days' notice to Lessee (which notice shall not be
required if Lessee is adjudicated a bankrupt or a trustee is appointed for
Lessee after a petition for reorganization or arrangement has been filed
against Lessee under the Bankruptcy Act of the United States, or a receiver is
appointed for Lessee's business or property and the order of adjudication or
for the appointment of a trustee or receiver has not been vacated within sixty
(60) days after the entry thereof), the right of Lessee to possession of the
Promises may be terminated and the mere retention of possession thereafter by
Lessee shall constitute a forcible detainer of the Promises, and if the Lessor
so elects, but not otherwise, and upon notice of such election, this agreement
shall thereupon terminate, and upon termination of Lessee's right of possession
as aforesaid, whether this agreement be terminated or not, Lessee agrees to
surrender possession of the Premises immediately.  Lessor hereby expressly
waives any and all right to distrain for rent due and any and all landlord's
liens or claim of such upon any or all property of Lessee and Lessee's Related
Parties, on the Premises or the Easement Areas.

     B.  Concurrently with the execution of this agreement, Lessor's
beneficiaries have executed an instrument entitled "Consent to Site Agreement
By Lessor's Beneficiaries" whereby said beneficiaries recognize and consent to
the terms of this agreement and agree that they will not take any action or
suffer any action to be taken which does in any way impair or limit the
performance by Lessor of its obligations under this agreement, or which does in
any way impair or limit the exercise by Lessee of its rights under this
agreement.  Lessor hereby agrees that any breach by any of Lessor's
beneficiaries, or by any of their respective heirs, executors, administrators,
personal representatives, successors or assigns, of any of the covenants
contained in said instrument shall constitute a breach by Lessor of its
obligations under this agreement.

     19. If any suit or action shall be brought to enforce any of the terms,
covenants or conditions of this agreement, to restrain any breach of this
agreement, to recover any rent under this agreement, to terminate this
agreement or to recover possession of the Premises, the party not prevailing in
such suit or action shall be liable to the prevailing party for the prevailing
party's costs and expenses, including, without limitation, court costs and
reasonable attorneys' fees, the amount of which shall be fixed by the court and
shall be made a part of any judgment rendered.  Each party shall pay all costs
and expenses, including, without limitation, court costs and reasonable
attorneys' fees, incurred or sustained by the other party in any litigation in
which the other party, without its fault, becomes involved or concerned by
reason of this agreement.

     20. All notices to be given under this agreement shall be in writing and
shall be delivered in person or mailed by United States registered or certified
mail, postage prepaid,

<PAGE>   17



return receipt requested, addressed to Lessor, if intended for it, at the
address for payment of rent, and addressed to Lessee, if intended for it, at

Business Manager, and shall be deemed given when personally delivered, or on
the date indicated on a return receipt that delivery was made or refused.
Either party hereto may change the place for notice to it by like written
notice to the other.

     21. Each party hereto represents that it has full power and authority to
enter into this agreement and to perform the covenants and obligations herein
contained.  Each person executing this agreement represents that he or she is
duly authorized to execute this agreement.

     22. This agreement and all the rights, covenants and obligations contained
in this agreement shall inure to the benefit of-and be binding upon Lessor,
Lessor's beneficiaries from time to time, Lessee, and their respective heirs,
executors, administrators, personal representatives, successors and assigns as
permitted by this agreement.

     23. A.  In any case where the approval or consent of Lessor is required
under this agreement, and if Lessor consists of more than one person or entity,
an approval or consent by any of the persons or entities comprising Lessor
shall be sufficient, and Lessee may rely upon such approval or consent.  In
furtherance thereof, each of the persons and entities comprising Lessor does
hereby irrevocably make, constitute and appoint each of the other persons and
entities comprising the Lessor, acting alone, as its, his or her agent and true
and lawful attorney-in-fact, for and in its, his or her name, place and stead
to approve, authorize, sign, execute, acknowledge and deliver any and all
documents, instruments and certificates in connection with approvals or
consents from time to time required, requested or otherwise to be given under
this agreement, hereby conferring upon said attorney the most comprehensive
powers possible to be given in connection with the foregoing, and hereby
ratifying all that said attorney lawfully shall do or cause to be done by
virtue of the power of attorney hereby conferred.

     B.  In any case where the approval or consent of either party hereto is
required under this agreement, such party shall not unreasonably delay or
withhold its approval or consent.

     24. This agreement represents the entire, integrated agreement of the
parties hereto.  No alteration, amendment or addition to this agreement shall
be binding upon any party hereto unless contained in a writing signed by the
parties.  If any clause, phrase, provision or portion of this agreement or the
application thereof to any person or circumstance shall be invalid or
unenforceable under applicable law, such event shall not affect, impair or
render invalid or unenforceable the reminder of this agreement, nor any other
clause, phrase, provision or portion hereof, nor shall it affect the
application of any clause, phrase, provision or portion hereof to other persons
or circumstances.  Changes in the number, gender and grammar of terms and
phrases herein, where necessary to conform this agreement to the circumstances
of Lessor and Lessee, shall in all cases be assumed as though in each case
fully expressed herein.  This agreement shall be construed in accordance with
the laws of the State of Illinois.

     25. Lessee shall have options to extend the Term of this agreement for two
(2) additional periods of ten (10) years each (the "Extended Terms') upon
giving written notice to Lessor of Lessee's exercise of any such option at
least one hundred twenty (120) days prior to the expiration of the original
Term or any Extended Term; provided that neither such option shall be

<PAGE>   18



exercisable if, at the time of exercise or at the time any such Extended Term
is to commence, Lessee is in default under this agreement and has failed to
cure such default within the time permitted under paragraph 18 of this
agreement; and provided that the second option to extend shall cease to exist
if Lessee does not exercise the first option to extend.  All of the terms and
provisions of this agreement shall be effective during each Extended Term,
except that the monthly rent payable during the first Extended Term shall be as
follows:

     $2,700 per month for the period from May 1, 2017 through April 30, 2022;
and

     $3,000 per month for the period from May 1, 2022 through April 30, 2027;

and the monthly rent payable during the second Extended Term shall be as
follows.

     $3,300 per month for the period from May 1, 2027 through April 30, 2032;
and

     $3,600 per month for the period from may 1, 2032 through April 30, 2037.

The word "Term" as used in this agreement shall include the Extended Terms when
and as Lessee's options to extend shall be exercised.

     26. As additional security for the performance of Lessee's obligations
under this agreement, Lessee has concurrently with the execution of this
agreement deposited with Lessor the sum of Three Thousand Dollars ($3,000) (the
"Security Deposit").  Lessor may apply any part or all of the Security Deposit
for the purpose of curing any defaults of Lessee under this agreement if (and
only if) Lessee has failed to cure any such default within the time permitted
under paragraph 18 of this agreement.  Lessee shall pay to Lessor within ten
(10) days after receipt of Lessor's written notice a sum of money to replenish
such amounts as are properly applied by Lessor from the Security Deposit so
that, at all times during the Term and any Extended Terms, the Security Deposit
will equal the aforesaid sum.  At the expiration or earlier termination of this
agreement, if Lessee is not then in default hereunder, Lessor shall return to
Lessee the Security Deposit, less such amounts, if any, as have been properly
applied by Lessor to cure any defaults of Lessee hereunder.  Lessor shall keep
the Security Deposit in an interest-bearing "money market account", or a
similar interest-bearing demand deposit account, of the type available from
major banks.  The interest earned on the Security Deposit shall be paid to
Lessee not less often than annually.

     27. If there occurs a casualty which partially or completely destroys the
improvements, additions and/or Equipment constructed, made or installed upon or
in the Premises, such event shall not relieve Lessee of the obligation to pay
rent hereunder.
     IN WITNESS WHEREOF, the parties have executed this agreement the day and
year first above written.

assessments, levies, impositions or charges, or the part thereof, to the extent
that they are so measured or based, shall be deemed to be included within the
term Impositions for the purposes hereof to the extent that such Impositions
would be payable if the Leased Premises were the only property of Landlord
subject to such Impositions, and Tenant shall pay and discharge the same as
herein provided in respect to the payment of Impositions.  There shall be

Impositions as the same become due and payable. The existence of said fund
shall not limit or alter Tenant's obligation to pay Impositions (respecting
which the fund was created; provided, however, that said fund shall be fully
utilized for the payment of Impositions). The amount of the fund shall be
re-adjusted annually, on the first day of the month after the tax bills showing

reflect the actual amount of Impositions).  Tenant shall not be entitled to
interest on said fund.

Imposition or charge upon or against the Leased Premises, or any part thereof,
or the improvements at any time situated thereon, so long as the Tenant shall
in good faith and with due diligence, contest the same of the validity thereof

collection of the Imposition or charge so contested; provided that, pending any
such legal proceedings Tenant shall give Landlord such security as may be
deemed satisfactory to Landlord to insure payment of the amount of the
Imposition or charge, and all interest and penalties thereon.  If, at any time
during the continuance of such contest, the Leased Premises or any part thereof
is, in the judgment of Landlord, in imminent danger of being forfeited or lost,

         (b)     To inspect the Leased Premises and to make repairs, additions
                 or alterations to the Leased Premises;

         (c)     To show the Leased Premises to prospective purchasers,
                 mortgagees, or other
<PAGE>   43

                 persons having a legitimate interest in viewing the same, and,
                 at any time within one (1) year prior to the expiration of the
                 Lease term, to persons wishing to rent the Leased Premises;

         (d)     During the last year of the Lease term, to place and maintain
                 the usual "For Rent" signs on the Leased Premises; and

         (e)     During the last ninety (90) days of the Lease term, if during
                 or prior to that time Tenant vacates the Leased Premises, to
                 decorate, remodel, repair, alter or otherwise prepare the
                 Leased Premises for new occupancy.

Landlord may enter upon the Leased Premises for any and all of the said
purposes and may exercise any and all of the foregoing rights hereby reserved
without being deemed guilty of an eviction or disturbance of Tenant's use or
possession of the Leased Premises, and without being liable in any manner to
Tenant.

                              XV.  QUIET ENJOYMENT

         15.0    Quiet Enjoyment.  So long as Tenant is not in default under
the covenants and agreements of this Lease, Tenant's quiet and peaceable
enjoyment of the Leased Premises shall not be disturbed or interfered with by
Landlord or by any person claiming by, through or under Landlord.

                       XVI.  SUBORDINATION OR SUPERIORITY

         16.0    Subordination or Superiority.  The rights and interest of
Tenant under this Lease shall be subject and subordinate to any first mortgage
or trust deed creating a first mortgage that may be placed upon the Leased
Premises by Landlord and to any and all advances to be made thereunder, and to
the interest thereon, and all renewals, replacements and extensions thereof, if
the mortgagee or trustee named in said mortgages or trust deeds shall elect to
subject and subordinate the rights and interest of Tenant under this Lease to
the lien of its mortgage or deed of trust and shall agree to recognize this
Lease of Tenant in the event of foreclosure if Tenant is not in default.  Any
such mortgagee or trustee may elect to give the rights and interest of Tenant
under this Lease priority over the lien of its mortgage or deed of trust.  In
the event of either such election and upon notification by such mortgagee or
trustee to Tenant to that effect, the rights and interest of Tenant under this
Lease shall be deemed to be subordinate to, or to have priority over, as the
case may be, the lien of said mortgage or trust deed, whether this Lease is
dated prior to or subsequent to the date of said mortgage or trust deed.
Tenant shall execute and deliver whatever instruments may be required for such
purposes, and in the event Tenant fails so to do within ten (10) days after
demand in writing.  Tenant does hereby make, constitute and irrevocably appoint
Landlord as its attorney in fact and in its name, place, and stead so to do.

                                XVII.  SURRENDER

         17.0    Surrender.  Upon the termination of this Lease whether by
forfeiture, lapse of time or otherwise, or upon the termination of Tenant's
right to possession of the Leased Premises, Tenant will at once surrender and
deliver up the Leased Premises, together with all improvements thereon, to
Landlord in good condition and repair, reasonable wear and tear excepted.  Said
improvements
<PAGE>   44

shall include all plumbing, lighting, electrical, heating, cooling, and
ventilating fixtures and equipment and other articles of personal property used
in the operation of the Leased Premises (as distinguished from operations
incident of the business of Tenant; articles of personal property incident to
Tenant's business are hereinafter referred to as "Trade Fixtures").  All
additions, hardware, non-Trade Fixtures and improvements, temporary or
permanent, in or upon the Leased Premises placed there by Tenant shall become
Landlord's property and shall remain upon the Leased Premises upon such
termination of this Lease by lapse of time or otherwise, without compensation
or allowance or credit to Tenant, unless Landlord requests their removal in
writing at or before the time of such termination of this Lease.  If Landlord
so requests removal of said additions, hardware, non-Trade Fixtures and all
improvements and Tenant does not make such removal at said termination of this
Lease, or within ten (10) days after such request, whichever is later, Landlord
may remove the same and deliver the same to any other place of business of
Tenant or warehouse the same, and Tenant shall pay the cost of such removal,
delivery and warehousing to Landlord on demand.

         17.1    Removal of Tenant's Property.  Upon the termination of this
Lease by lapse of time, Tenant may remove Tenant's Trade Fixtures provided,
however, that Tenant shall repair any injury or damage to the Leased Premises
which may result from such removals.  If Tenant does not remove Tenant's Trade
Fixtures from the Leased Premises prior to the end of the term, however ended,
Landlord may, at its option, remove the same and deliver the same to any other
place of business of Tenant or warehouse the same, and Tenant shall pay the
cost of such removal (including the repair of any injury or damage to the
Leased Premises resulting from such removal), delivery and warehousing to
Landlord on demand, or Landlord may treat such Trade Fixtures as having been
conveyed to Landlord with this Lease as a Bill of Sale, without further payment
or credit by Landlord to Tenant.

         17.2     Holding Over.  Any holding over by Tenant of the Leased
Premises after the expiration of this Lease shall operate and be construed to
be a tenancy from month to month only, at the same monthly rate of rent and
other charges payable hereunder for the Lease term, or at the election of
Landlord expressed in a written notice to Tenant, otherwise holding over shall
constitute a renewal of the Lease for one (1) year at the same rental at which
all of the covenants and agreements contained in this Lease.  If Tenant
continues to hold over any written demand by Landlord for possession at the
expiration of the Lease or after termination by either of a month to month
tenancy created pursuant to this Section, or after termination of the Lease or
of double the rate of rent payable hereunder immediately prior to the
expiration or other termination of the Lease of Tenant's right to possession.
Nothing contained in this Section 17.2 shall be construed to give Tenant the
right to hold over at any time and Landlord may exercise any and all remedies
at law or in equity to recover possession of the Leased Premises.

                                XVIII. REMEDIES

         18.0    Defaults.  Tenant further agrees that any one or more of the
following events shall  be considered events of default as said term is used
herein, that is to any, if

         (a) Tenant shall be adjudged an involuntary bankrupt, or a decree or
         order approving, as properly filed, a petition or answer filed against
         Tenant asking recognition of Tenant under the Federal bankruptcy law
         as now or hereafter amended, or under the laws of any State, shall be
         entered, and any such decree or judgment or order shall not have been
         vacated or set
<PAGE>   45

         aside within sixty (60) days from the date of the entry or granting
         thereof; or

         (b) Tenant shall file or admit the jurisdiction of the court and the
         material allegations contained in, any petition in bankruptcy, or any
         petition pursuant or purporting to be pursuant to the Federal
         bankruptcy laws as now or hereafter amended, or Tenant shall institute
         any proceedings or shall give its consent to the institution of any
         proceedings for any relief of Tenant under any bankruptcy or
         insolvency laws or any laws relating to the relief of debtors,
         readjustment of indebtedness, reorganization, arrangements,
         composition or extension: or

         (c)  Tenant shall make any assignment for the benefit of creditors or
         shall apply for or consent to the appointment of a receiver for Tenant
         or any of the property of Tenant; or

         (d)  The Leased Premises are levied upon by any revenue officer or
         similar officer, or

         (e)  A decree or order appointing a receiver of the property of Tenant
         shall be made and such decree or order shall not have been vacated or
         set aside within sixty (60) days from the date of entry or granting
         thereof, or

         (f)   Tenant shall abandon the Leased Premises or vacate the same
         during the tem hereof; or

         (g) Tenant shall default in any monthly payments of rent or in any
         other payment required to be made by Tenant hereunder when due as
         herein provided and such default shall continue for ten (10) days
         after notice thereof in writing to Tenant.; or

         (h)  Tenant shall fail to contest the validity of any lien or claimed
         lien and give security to Landlord to insure payment thereof, or
         having commenced to contest the same and having given such security,
         shall fail to prosecute such contest with diligence, or shall fail to
         have the some released and satisfy any judgment rendered thereon, and
         such default continues for ten (10) days after notice thereof in
         writing to Tenant; or

         (i) Tenant shall default in any of the other covenants and agreements
         herein contained to be kept, observed and performed by Tenant, and
         such default shall continue for thirty (30) days after notice thereof
         in writing to Tenant; or

         (j)  Tenant shall repeatedly be late in the payment of rent or other
         charges required to be paid hereunder or shall repeatedly default in
         the keeping, observing, or performing of any other covenants or
         agreements herein contained to be kept,. observed or performed by
         Tenant (provided notice of such payment or other defaults shall have
         been given to Tenant, but whether or not Tenant shall have timely
         cured any such payment or other defaults of which notice was given).

Upon the occurrence of any one or more of such events of default, Landlord may
at its election terminate this Lease or terminate Tenant's right to possession
only, without terminating the Lease.  Upon termination of this Lease or of
Tenant's right to possession, Landlord may re-enter the Leased Premises with or
without process of law using such force as may be necessary, and remove all
persons, fixtures, and chattels therefrom and Landlord shall not be liable for
any damages resultant therefrom.  Upon termination of the Lease, or upon any
termination of the Tenant's right to
<PAGE>   46

possession without termination of the Lease, the Tenant shall surrender
possession and vacate the Leased Premises immediately, and deliver possession
thereof to the Landlord, and hereby grants to the Landlord the full and free
right, without demand or notice of any kind to Tenant (except as hereinabove
expressly provided for), to enter into and upon the Leased Premises in such
event with or without process of law and to repossess the Leased Premises as
the Landlord's former estate and to expel or remove the Tenant and any others
who may be occupying or within the Leased Premises without being deemed in any
manner guilty of trespass, eviction, or forcible entry or detainer without
incurring any liability for any damage resulting therefrom and without
relinquishing the Landlord's rights to rent or any other right given to the
Landlord hereunder or by operation of law.  Upon termination of the Lease,
Landlord shall be entitled to recover as damages, all rent and other sums due
and payable by Tenant on the date of termination, plus (1) an amount equal to
the value of the rent and other sums provided herein to be paid by Tenant for
the residue of the stated term hereof, less the fair rental value of the Leased
Premises for the residue of the stated term (taking into account the time and
expenses necessary to obtain a replacement tenant or tenants, including
expenses hereinafter described relating to recovery of the premises,
preparation for reletting and for reletting itself), and (2) the cost of
performing any other covenants to be performed by Tenant.  If the Landlord
elects to terminate the Tenant's right to possession only, without terminating
the Lease, the Landlord may, at the Landlord's option enter into the Leased
Premises, remove the Tenant's signs and other evidences of tenancy, and take
and hold possession thereof as hereinabove provided, without such entry and
possession terminating the Lease or releasing the Tenant, in whole or in part,
from the Tenant's obligations to pay the rent hereunder for the full term or
from any other of its obligations under this Lease.  Landlord may, but shall be
under no obligation so to do, relet all or any part of the Leased Premises for
such rent and upon terms that shall be satisfactory to Landlord (including the
right to rent the Leased Premises for a term greater than that remaining under
the Lease term, and the right to relet the Leased Premises as a part of a
larger area, and the right to change the character of use made of the Leased
Premises).  For the purpose of such reletting, Landlord may decorate or make
any repairs, changes, alterations or additions in or to the Leased Premises
that may be convenient.  If Landlord does not relet the Leased Premises, Tenant
shall pay to Landlord on demand damages equal to the amount of the rent, and
other sums provided herein to be paid by Tenant for the remainder of the Lease
term.  If the Leased Premises are relet and a sufficient sum shall not be
realized from such reletting after paying all of the expenses of such
decoration, repairs, changes, alternations, additions, the expenses of such
reletting and the collection of the rent accruing therefrom including, but not
by way of limitation, attorneys' fees and brokers' commissions, to satisfy the
rent herein provided to be paid for the remainder of the Lease term.  Tenant
shall pay to Landlord on demand any deficiency and Tenant agrees that Landlord
may file suit to recover any sums falling due under the terms of this Section
from time to time.  If Tenant shall default under subsection (1) hereof, and if
such default cannot with due diligence be cured within a period of thirty (30)
days, and if notice thereof in writing shall have been given to Tenant, and if
Tenant promptly commences to eliminate the cause of such default, then Landlord
shall not have the right to declare said term ended by reason of such default
or to repossess the Leased Premises without terminating the Lease so long as
Tenant is proceeding diligently and with reasonable dispatch to take all steps
and do all work required to cure such default and does so cure such default,
provided, however, that the curing of any default in such manner shall not be
construed to limit or restrict the right of Landlord to declare the term ended
or to repossess without terminating the Lease, and to enforce all of its right
and remedies hereunder for any other default no so cured.

     18.1        Remedies Cumulative.  No remedy herein or otherwise conferred
upon or reserved to Landlord shall be considered to exclude or suspend any
other remedy but the same shall be
<PAGE>   47

cumulative and shall he in addition to every other remedy given hereunder, or
now or hereafter existing at law or in equity or by statute, and every power
and remedy given by this Lease to Landlord may be exercised from time to Lime
and so often as occasion may arise or as may be deemed expedient

     18.2        No Waiver.  No delay or omission of Landlord to exercise any
right or power arising from any default shall impair any such right or power or
be construed to be a waiver of any such default or any acquiescence therein.
No waiver of any breach of any of the covenants of this Lease shall be
construed, taken or held to be a waiver of any other breach or waiver,
acquiescence in or consent to any further or succeeding breach of the same
covenant.  The acceptance by Landlord of any payment of rent or other charges
hereunder after the termination by Landlord of this Lease or of Tenant's right
to possession hereunder shall not. in the absence of agreement in writing to
the contrary by Landlord, be deemed to restore this Lease or Tenant's right to
possession hereunder, as the case may be, but shall be construed as a payment
on account, and not in satisfaction, of damages due from Tenant to Landlord.

                              Section 18.3 Omitted

                             XIX.  SECURITY DEPOSIT

Tenant of all of the covenants, conditions and agreements in this Lease set
forth and contained on the part of the Tenant to be fulfilled, kept, observed
and performed, including, but without limiting the generality of the foregoing,
such covenants, conditions and agreements in this Lease which become applicable
upon the termination of the same by re-entry or otherwise, Tenant has deposited
herewith the sum of $55,000 with David Unger & Henry Mautner as beneficiaries
of Landlord("Agent") as a Security Deposit on the understanding: (a) that such
deposit or any part or portion thereof not previously applied, or from time to
time, such one or more parts or portions thereof, may be applied to the curing
of any default that may then exist, without prejudice to any other remedy or
remedies which the Landlord may have on account thereof, and upon such
application Tenant shall pay Agent on demand the amount so applied which shall
be added to the Security Deposit so the same may be restored to its anginal
amount; (b) that should the Leased Premises be conveyed by Landlord or should
Agent cease to be the beneficiaries of Landlord, the deposit or any portion
thereof not previously applied may be turned over to Landlord's grantee or the
new agent, as the case may be, and if the same be turned over as aforesaid, the
Tenant hereby releases Landlord and Agent from any and all liability with
respect to the deposit and/or its application or return, and the Tenant agrees
to look to such grantee or agent, as the case may be, for such application or
return; (c) that Landlord shall have no personal liability with respect to said
sum and Tenant shall look exclusively to Agent or its successors pursuant to
subparagraph (b) hereof for return of said sum on the termination of this
lease; (d) that Agent or its successor shall not be obligated to hold said
deposit as a separate fund, but on the contrary may commingle the same with its
other funds; (e) that if Tenant shall faithfully fulfill, keep, perform and
observe all of the covenants, conditions, and agreement in this Lease set forth
and contained on the part of Tenant to be fulfilled, kept, performed and
observed, the sum deposited or the part or portion thereof not previously
applied, shall be returned to the Tenant without interest no later than thirty
(30) days after the expiration of the term of this Lease or any renewal or
extension thereof, provided Tenant has vacated the Leased Premises and
surrendered possession thereof to the Landlord at the expiration of said term
or any extension or renewal thereof as provided herein; and (f) that Agent on
behalf of itself and its successor, reserves the right, at its
<PAGE>   48

sole option, to return to Tenant said deposit or what may then remain thereof,
at any time prior to the date when Agent, or its successors is obligated
hereunder to return the same, but said return shall not in any manner be deemed
to be a waiver of any default of the Tenant hereunder then existing nor to
limit or extinguish any liability of Tenant hereunder.

If Landlord is an Illinois Land Trust, the following Section 21.0 shall be

     21.0        Exculpatory Clause.  This Lease is executed by American
National Bank & Trust Company, not personally but as Trustee as aforesaid, in
the exercise of and power and authority conferred upon and vested in it as such
Trustee, and under the express direction of the beneficiaries of a certain
Trust Agreement dated September 15, 1976, and known as Trust Number 39340 to
all provisions of which Trust Agreement this Lease is expressly made subject.
It is expressly understood and agreed that nothing in this Lease contained
shall be construed as creating any liability whatsoever against said Trustee or
said beneficiaries, 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, to keep, preserve or acquiesce any property of said Trust, and that
all personal liability of said Trustee (and said beneficiaries to the extent
permitted by law), of every sort, if any, is hereby expressly waived by Tenant,
