contained.  In addition, Lessee shall have three (3) options to renew the Lease
term for an additional five (5) years per option.  Each option to renew may be
exercised by Lessee providing Lessor written notice of Lessee's intention to
exercise that option, which written notice shall be given not less than thirty
(30), but not more than ninety (90), days before the expiration of the then
current lease term (including as extended by virtue of options to renew

nonpayment of any late charges, Lessor shall have, in addition to all other
rights and remedies, all the rights and remedies provided for herein and by law
for nonpayment of rent.  No failure by Lessor to insist upon the strict
performance by Lessee of Lessee's obligations to timely pay late charges shall
constitute a waiver by Lessor of its rights to enforce the provisions of this
Section in any instance thereafter occurring or to demand payment of accrued
and unpaid late charges.

         SECTION 2.7.  REAL PROPERTY TAXES AND ASSESSMENTS: Lessor shall pay,

                  PERSONAL PROPERTY, FIXTURES, MAINTENANCE
                                     AND
                           ALTERATION OF PREMISES

          SECTION 4.1. ALTERATIONS, FIXTURES, AND IMPROVEMENTS:  All
Improvements installed upon the Leased Premises by Lessee shall be or remain
the property of Lessor.  All Improvements made or placed in or on the Leased
Premises by Lessee shall, on expiration or earlier termination of this Lease,
belong to Lessor without compensation to Lessee, provided, however, that Lessor
shall have the option, to be exercised not less than ninety (90) days prior to
the expiration or earlier termination of this Lease, to require Lessee to
remove any or all such Improvements.  Before making any structural alterations
or modifications to the Leased Premises, Lessee shall submit plans and designs
therefor to Lessor for approval, which approval shall not be unreasonably

disapproved by Lessor, such modifications shall not be installed.

          SECTION 4.2. COMPLIANCE WITH THE AMERICANS WITH DISABILITIES ACT:
Lessee assumes all liability, obligation and expense for compliance with the

<PAGE>   6

Leased Premises only if required because of tenant's specific use of the Leased
Premises.  To the extent that such compliance with the Act requires alteration
of the Leased Premises and consent by Lessor under Section 4.1, such consent
shall not be unreasonably withheld.  Lessee further agrees to indemnify and
hold Lessor harmless for any claim made against Lessor arising from, through or
in any manner relating to the Lessee's non-compliance with this provision.

         SECTION 4.3.  FIXTURES AND PERSONAL PROPERTY:  Any equipment,
inventory, or other personal property stored or situated on or about the Leased
Premises by and at the expense of Lessee shall remain the property of Lessee,

property which it may have stored or situated on or about the Leased Premises.

         SECTION 4.4.  CONDITION AND REPAIR OF PREMISES:  Lessor will keep the
structural elements and exterior of the Leased Premises in good repair

interior of said premises in good repair, replacing all broken glass with glass
of the same size and quality of that broken, and will keep the Leased Premises
and appurtenances, as well as all catch basins, drains, stools lavatories,
sidewalks, adjoining alleys and all other facilities and equipment located
within the interior of Leased Premises, according to the applicable rules,
regulations, laws and ordinances, and the direction of the proper public
officers, during the term of the Lease, at its own expense.  Upon the
termination of this Lease in any way, Lessee will yield up said premises to
Lessor in good condition and repair (loss by fire or  other casualty,
condemnation and ordinary wear excepted) and will deliver the keys to Lessor.

         SECTION 4.5.  DAMAGE AND DESTRUCTION:  In the event the Leased
Premises are damaged by any peril covered by Lessor's policies of insurance to
an extent which is less than twenty-five percent (25%) of the cost of
replacement of the Leased Premises, the damage to that portion of the Leased
Premises together with such of Lessee's installations that become a part of the
real property shall promptly be repaired by Lessor, at Lessor's expense, except
under the conditions hereinafter stated.  Lessor shall not be obligated to
expend for such repairs an amount in excess of the insurance proceeds recovered
as a result of such damage and in no event shall Lessor be required to repair
or replace Lessee's stock-in-trade, trade fixtures, furniture, furnishings, or
other property which Lessee is required to insure under the terms of this
Lease.  In the event of such damage and (a) Lessor is not required to repair as
hereinabove provided, or, (b) the Leased Premises are damaged to the extent of
twenty-five percent (25%) or more of the costs of replacement of the Leased
Premises, or (c) the building of which the Leased Premises are a part is
damaged to the extent of fifty percent (50%) or more of the cost of
replacement, or (d) such damage occurs during the last year of the term of this
Lease, and Lessor and Lessee do not agree upon an extension of this Lease or
Lessee fails to exercise an option





                                      6
<PAGE>   7

to renew this Lease should there be such right, Lessor may elect either to
repair or rebuild the Leased Premises or the building of which the Leased
Premises are a part, as the case may be, or to terminate this Lease upon giving
notice of such election in writing to Lessee within sixty (60) days after the
occurrence of the event causing the damage.  If the casualty, repairing, or
rebuilding shall render the Leased Premises untenantable, in whole or in part,
a proportionate abatement of the Base Rent shall be allowed from the date when
the damage occurred until the date Lessor completes the repairs or rebuilding,
the proportion to be computed on the basis of the relation which the
untenantable portion of the Leased Premises bears to the gross square foot area
of the Leased Premises.  If Lessor is required or elects to repair the Leased
Premises as herein provided, Lessee shall repair or replace its stock-in-trade,
trade fixtures, furniture, adornments, special equipment, and all other items
of Lessee's personal property located on or within the Leased Premises and all
Improvements previously installed by Lessee upon the Leased Premises such
repair and replacement by Lessee shall be in a manner and to at least a
condition equal to that existing prior to the damage or destruction.

charges for utilities used by Lessee, which are separately measured and
assessed to the Leased Premises.

         SECTION 4.7.  SIGNS:  Lessor agrees to permit Lessee to place signs
advertising Lessee, or the goods, wares or services offered by Lessee, in and
about the Leased Premises, upon the exterior of any buildings thereon and to

harmonious in size, style and type to other signs as may be erected in the
neighborhood or vicinity immediately surrounding the Leased Premises.

express written consent of Lessor, which consent shall not be unreasonably
withheld or delayed.

                                 ARTICLE 5.
                                  INSURANCE

         SECTION 5.1.  LESSEE'S OBLIGATION TO MAINTAIN:  During the term of
this lease, Lessee shall maintain, or cause to be maintained, at Lessee's sole
cost and expense, policies of insurance as follows:

                 5.1.1.  FIRE INSURANCE:  Lessee will at all times during the
         term of this Lease insure and keep in effect on the Leased Premises,
         fire and casualty insurance with additional coverage commonly known as
         supplemental contract or extended coverage, in the amount of the
         replacement value of the Improvements on the Leased Premises, written
         by an insurance company or companies authorized to do business in the
         State of Indiana.  Lessee shall name Lessor as an "additional insured"
         and shall cause all notices including invoices from the insurer to be





                                      7

<PAGE>   8

         simultaneously made to Lessor at Lessor's address stated herein.
         Also, Lessee shall not be allowed to cancel such insurance for any
         reason without first notifying Lessor in writing ten (10) days prior
         to the intended cancellation.  Lessee shall also obtain insurance
         against loss or damage to Lessee's stock-in-trade, trade fixtures,
         furniture, adornments, special equipment, floor and wall coverings,
         and all other items of Lessee's personal property located on or within
         the Leased Premises and also upon all Improvements installed by Lessee
         upon the Leased Premises.  Such insurance shall include fire and
         extended coverage and coverage for such other hazards as may be
         covered by the form of all-risk insurance in effect, in an amount
         sufficient to cover at least eighty percent (80%) of the replacement
         cost (without depreciation) of such property and to prevent any
         co-insurance provision from becoming effective.

                 5.1.2.  GENERAL LIABILITY INSURANCE:  Lessee shall obtain
         Comprehensive general liability insurance (containing so-called
         "occurrence clause") against claims for bodily injury, death, and
         property damage occurring in or about the Leased Premises, including
         but not limited to any streets, alleys, sidewalks or parking areas,
         malls, vaults, passageways, or common areas adjoining or appurtenant
         to the Leased Premises.  Such insurance shall afford minimum
         protection of $1,000,000.00 with respect to the personal injury or
         death occurring or resulting from one occurrence and $100,000.00 with
         respect to property damage.

                 5.1.3.  OTHER INSURANCE REQUIRED:  Lessee shall obtain such
         other insurance in such amounts as may from time to time be reasonably
         required by Lessor or any mortgagee against other insurable hazards
         which at the time are commonly insured against in the case of premises
         similarly situated.

         SECTION 5.2.    INCREASE IN POLICY LIMITS:  If by reason of changed
economic conditions the insurance amounts referred to above become inadequate,
Lessee agrees to increase the amounts of such insurance promptly upon Lessor's
request.  All policies of insurance carried by Lessee pursuant to this Lease
shall name Lessor and Lessee as insureds, and, if required, any mortgagee, as
their respective interests may appear; provided, however, that rent insurance
shall provide that the proceeds thereof shall be paid to Lessor solely and said
proceeds shall then be held by Lessor as security for the payment of the rent
provided for herein until restoration of the Leased Premises by Lessee.  To the
extent Lessor receives and applies the proceeds of rent insurance, Lessee shall
receive a credit against net annual rent payable hereunder.

         SECTION 5.3.    RESPONSIBILITY FOR PREMIUMS:  All premiums on policies
of insurance which Lessee is obligated to obtain shall be paid by Lessee.  The
originals of such policies shall be delivered to Lessor except when such
originals are required to be held by any mortgagee, in which case certificates
of insurance shall be delivered to Lessor.  Policies or certificates with
respect to renewal policies shall be delivered to Lessor by Lessee not





                                      8

<PAGE>   9

less than thirty (30) days prior to the expiration of the original policies, or
succeeding renewals, as the case may be, together with receipts or other
evidence that the premiums thereon have been paid for at least one year. 
Premiums on polices shall not be financed in any manner whereby the lender, on
default or otherwise, shall have the right or privilege of surrendering or
canceling the policies; provided, however, that Lessee may pay premiums in
annual installments so long as such method of payment does not constitute a
default under any mortgage.

         SECTION 5.4.  LIMITATION OF OBLIGATION AND CANCELLATION:   Each policy
of insurance required of Lessee under this Lease shall have attached thereto an
endorsement that such policy shall not be canceled or modified without at least
ten (10) days' prior written notice to Lessor, and, if required, to each
mortgagee.  Each such policy shall contain a provision that no act or omission
of Lessee shall affect or limit the obligation of the insurer to pay the amount
of any loss sustained.

         SECTION 5.5.  SATISFACTION OF INSURER'S REQUIREMENTS:  Lessee shall so
perform and satisfy the requirements of the companies writing any insurance
policies referred to in this Lease so that at all times insurers of recognized
responsibility satisfactory to Lessor shall be willing to issue or continue
such policies of insurance.

         SECTION 5.6.  APPROVED INSURERS:  All insurance provided for in this
Lease shall be effected under valid and enforceable policies issued by insurers
of recognized responsibility which are licensed to do business in the State of
Indiana.

         SECTION 5.7.  WAIVER OF SUBROGATION:  Each policy of insurance
provided for in this Lease shall contain the standard form of waiver of
subrogation.

         SECTION 5.8.  FAILURE TO SECURE INSURANCE:  If Lessee, at any time
during the term hereof, fails to secure or maintain the insurance required
hereunder, Lessor shall be permitted to obtain such insurance in Lessee's name
or as the agent of Lessee and Lessee shall pay Lessor as additional rent the
cost of such insurance.

         SECTION 5.9.  INDEMNITY:  Lessee, during the term hereof, shall
indemnify and save harmless Lessor from and against any and all claims and
demands, whether for injuries to persons or loss of life, or damage to
property, occurring on or about the Leased Premises and arising out of the use
and occupancy of the Leased Premises by Lessee.

         SECTION 5.10.  INSURANCE HAZARDS  PROHIBITED:  Lessee shall not commit
or permit any act or acts in or on the Leased Premises or use the Leased
Premises or suffer them to be used in any manner which will increase the
existing fire, liability, and other insurance rates on the Leased Premises or
which will cause a cancellation of any insurance policy covering the Leased
Premises or any portion thereof.  Lessee shall not keep, hold, store, use, or
sell in or on the Leased Premises any product or article prohibited by the
standard





                                      9

<PAGE>   10

form fire insurance policy, as it now exists or may hereafter provide, covering
the Leased Premises and its contents, or permit or suffer any such product or
article to be kept, held, stored, used, or sold in or on the Leased Premises
and Lessee shall, at Lessee's sole expense, comply with any and all
requirements of Lessor's insurance carriers pertaining to the Leased Premises
necessary for the continued maintenance of fire and liability insurance at
standard rates of the Leased Premises and appurtenances thereto.  If any act or
failure to act by Lessee shall cause an increase of insurance premiums paid by
Lessor, Lessee shall pay all such increases within fifteen (15) days of
Lessor's demand thereof.

         SECTION 5.11.  LESSOR'S INSURANCE OBLIGATION:  Lessor may obtain its

         SECTION 6.2.  NOTICE OF DEFAULT AND TERMINATION:  If an Event of
Default shall occur, Lessor, at any time thereafter, may at its option give
notice thereof to Lessee stating that this Lease and the term hereby demised
shall expire and terminate on the date specified in such notice,  and upon the
date specified in such notice, this Lease and the term hereby demised, and all
rights of Lessee under this Lease shall expire and terminate as if that date
were the date herein definitely fixed for the termination of the term of this
Lease.  Lessee shall thereupon quit and surrender the Leased Premises but shall
remain liable as hereinafter provided.  After any such termination Lessor may
at its option file a written declaration of termination in the official records
of the county in which the Leased Premises are located, which written
declaration shall be deemed a conclusive termination of this Lease.

         SECTION 6.3.  REENTRY BY LESSOR:  If any Event of Default shall occur,

force for that purpose as may be necessary without being liable to indictment,
prosecution, or damages therefor, and Lessee shall nevertheless remain liable

expense of retaking, repossessing, repairing and/or altering the Leased
Premises, and the cost and expense of removing all persons and property
therefrom; second, receive payment for the cost and expense sustained in
securing any new lessees, and if Lessor shall maintain and operate the Leased
Premises, the costs and expense of operating and maintaining the Leased
Premises; and, third, receive payment for any balance remaining on account of
the liability of Lessee to Lessor.  No reentry by Lessor shall absolve or
discharge Lessee from liability hereunder.  Lessor shall not be responsible or
liable for any failure to relet the Leased Premises or any part thereof, or for
any failure to collect any rent due on any such reletting.  If any rent so
collected by Lessor after the aforementioned payments be insufficient to fully
pay to Lessor a sum equal to all such rent and other payments and charges
reserved herein, the deficiency shall be paid by Lessee on the dates herein
specified for payment of rent.

         SECTION 6.4.    REMEDIES CUMULATIVE:  No remedy herein or otherwise
conferred upon or reserved to Lessor shall be considered to exclude or suspend
any other remedy, but the same shall be cumulative and shall be in addition to
every other remedy given hereunder, or now or hereafter existing at law or in
equity or by statute.  Every power and remedy given by this Lease to Lessor may
be exercised from time to time and so often as occasion may arise or as may be
deemed expedient.

         SECTION 8.1.  "EMINENT DOMAIN" DEFINED:  "Eminent domain" is the power
to take private property for public or quasi-public use.  As used in this
Lease, the words "condemned" and "condemnation" are coextensive with such
right, and a voluntary conveyance by Lessor to the condemnor under threat of a
taking under the power of eminent domain in lieu of or after commencement of
formal proceedings shall be deemed to be such a taking within the meaning of
this Lease.

under such power as to prevent or substantially impair the conduct of Lessee's
business thereon.

         SECTION 8.3.  "PARTIAL CONDEMNATION" DEFINED:  As used in this Lease,
the terms "partial condemnation" and "partial taking" mean the taking of a
portion of the Leased Premises under the power of eminent domain where such
taking does not constitute a total taking as defined in this Lease.

         SECTION 8.4.  EFFECT OF TOTAL CONDEMNATION:

                 8.4.1.  TERMINATION OF LEASEHOLD:  In the event that there is
         a total condemnation of the Leased Premises during the lease term or
         any extension hereof, the leasehold estate hereby created shall cease
         and terminate as of  the date title to the property is taken by the
         condemnor or at the time the condemnor is authorized to take
         possession of the property as stated in an order for possession,
         whichever is earlier.

                 8.4.2.  DISPOSITION OF AWARD:  Upon such total condemnation as
         in this Section provided, all compensation and damages for such taking
         shall belong to and be the sole property of Lessor, and Lessee shall
         have no claim thereto and hereby irrevocably assigns and transfers to
         Lessor all right, title and interest Lessee may have to compensation
         for damages to which Lessee may become entitled thereby.
         Notwithstanding the foregoing, Lessee shall be entitled to receive any
         award made for the taking of or damage to Lessee's trade fixtures and
         any Improvements made by Lessee to the Leased Premises which Lessee
         would have had the right to remove on expiration or earlier
         termination of this Lease but for the condemnation and for any
         reasonable and necessary moving expenses.

                 8.4.3.  RENT OBLIGATION:  Upon termination of this Lease by a
         total condemnation of the Leased Premises, all rents and other charges
         payable by Lessee to or on behalf of Lessor under the provisions of
         this Lease shall be paid up to the date on which actual physical
         possession of the Leased Premises shall be taken by the condemnor.
         The parties hereto shall thereafter be released from all further
         liability in relation thereto.

         SECTION 8.5.  EFFECT OF PARTIAL CONDEMNATION:

                 8.5.1.  TERMINATION OF LEASEHOLD:  In the event that there is
         a partial condemnation of the Leased Premises during the lease term or
         any extension hereof, this Lease shall terminate as to the portion of
         the Leased Premises so taken on the date title to the property is
         taken by the condemnor or at the time the condemnor is authorized to
         take possession of the property as stated in an order for possession,
         whichever is earlier.

<PAGE>   17


                 8.5.2.  DISPOSITION OF AWARD:  Upon such partial condemnation,
         all compensation and damages for such partial condemnation shall
         belong to and be the sole property of Lessor, and Lessee shall have no
         claim thereto and hereby irrevocably assigns and transfers to Lessor
         all right, title and interest Lessee may have to compensation for
         damages to which Lessee may become entitled thereby.  Notwithstanding
         the foregoing, Lessee shall be entitled to receive any award made for
         the taking of or damage to Lessee's trade fixtures and any
         Improvements made by Lessee to the Leased Premises which Lessee would
         have had the right to remove on expiration or earlier termination of
         this Lease but for the condemnation.

                 8.5.3.  REPAIR OF THE LEASED PREMISES:  In the event the
         Leased Premises are condemned in an amount which is less than
         twenty-five percent (25%) of the cost of replacement of the  Premises,
         the damage to that portion of the Leased Premises and the improvements
         shall promptly be repaired by Lessor, at Lessor's expense, except
         under the conditions hereinafter stated.  Lessor shall not be
         obligated to expend for such repairs an amount in excess of the
         condemnation proceeds recovered.  In no event shall Lessor be required
         to repair or replace Lessee's stock-in-trade, trade fixtures,
         furniture, furnishings, or other property of Lessee.  In the event of
         a condemnation and (a) Lessor is not required to repair as hereinabove
         provided, or, (b) the Leased Premises are condemned to the extent of
         twenty-five percent (25%) or more of the cost of replacement of the
         Leased Premises, or (c) such condemnation occurs during the last year
         of the term of this Lease, and Lessor and Lessee do not agree upon an
         extension of this Lease or Lessee fails to exercise its option to
         renew this Lease should there be such right, Lessor may elect either
         to repair or rebuild the Leased Premises or to terminate this Lease by
         giving Lessee thirty (30) days notice of the same.  If the repairing
         or rebuilding of the Leased Premises renders the Leased Premises
         untenantable, in whole or in part, a proportionate abatement of the
         Base Rent shall be allowed from the date when the condemnation
         occurred until the date Lessor completes the repairs or rebuilding,
         the proportion to be computed on the basis of the relation which the
         untenantable portion of the Leased Premises bears to the gross square
         foot area of the Leased Premises.  If Lessor is required or elects to
         repair the Leased Premises as herein provided, Lessee shall repair or
         replace its stock-in-trade, trade fixtures, furniture, adornments,
         special equipment, and all other items of personal property of Lessee
         located on or within the Leased Premises and all Improvements
         previously installed by Lessee upon the Leased Premises.  Such repair
         and replacement by Lessee shall be in a manner and in a condition at
         least equal to that existing prior to the damage or destruction.

                 8.5.4.  RENT OBLIGATION:  Upon termination of this Lease in
         whole or in part as herein provided, all rentals and other charges
         payable by Lessee to or on behalf of Lessor hereunder shall be paid up
         by Lessee to the date on which actual physical possession shall be
         taken by the condemnor, and, Lessee shall thereafter be liable





                                      17
<PAGE>   18

         only for rent in an amount in proportion to the amount of the Leased
         Premises remaining.

                                  ARTICLE 9.
                       MISCELLANEOUS RIGHTS AND DUTIES

         SECTION 9.1.  ASSIGNMENT AND SUBLETTING:  Lessee shall not assign any
interest in this Lease or sublet the Leased Premises, or any part thereof,
without the express written consent of Lessor obtained in advance which consent
shall not be unreasonably withheld or delayed.

         SECTION 9.2.  INSPECTION  BY LESSOR:  Upon reasonable prior notice,
Lessor shall have the right to inspect the Leased Premises at any time during
normal business hours and during the last ninety (90) days of the term of this
Lease, to advertise the Leased Premises as for sale or rent and to enter the
Leased Premises for the purpose of showing the same to prospective lessees or
purchasers.

         SECTION 9.3.  NON-WAIVER:  Any waiver by Lessor of any Event of
Default or breach of this Lease shall not be construed as a waiver of
subsequent Events of Default or breaches which may be committed by Lessee, and
failure of Lessor to exercise any right or remedy herein granted to Lessor
shall not operate as a waiver of such right or remedy.

         SECTION 9.4.  WAIVER OF LESSOR LIABILITY:  Lessor shall not be liable
for any damage either to person or property sustained by Lessee or by other
persons due to any act or neglect of any other person other than Lessor, its
employees, agents, invitees, Licensees, or contractors.  If any damage shall be
caused to the Leased Premises by the acts or neglect of Lessee, its employees,
agents, invitees, licensees, or contractors, Lessor may, at its option, repair
such damage, and Lessee shall on demand reimburse Lessor for any amount
expended.  Lessee further agrees that all personal property upon the Leased
Premises, whether belonging to Lessee or to any other person, shall be at the
risk of Lessee only, and Lessor shall not be liable for any damage thereto or
theft thereof.  Lessee  hereby waives any claim against Lessor, including
incidental and consequential damages, arising from, through or in any manner
related to this Lease, the Leased Premises, Lessor's negligence or Lessor's
obligations hereunder.

         SECTION 9.5.  CONDITION OF LEASED PREMISES:  The Leased Premises are
leased to Lessee "AS IS".  Lessor makes no representation or warranty of any
kind concerning the condition of the Leased Premises.  Lessee assumes all
obligations for the care and maintenance of the Leased Premises not
specifically assumed herein by Lessor.

         SECTION 9.6.  LESSOR'S WARRANTIES:  Lessor warrants that Lessee shall
have peaceful possession and quiet enjoyment of the Leased Premises during the
term of this Lease (including any renewal thereof) and that Lessee may use the
same in the manner





                                      18

<PAGE>   19

provided in Section 1.4, including any activities which are ancillary or
incident to such use; provided, however, that Lessee shall, at its own cost and
expense, obtain any and all licenses and permits necessary for any such use.

         SECTION 9.7.  HOLDOVER PROVISIONS:   If Lessee fails to notify Lessor
in the manner provided in this Section of its intention to exercise this option
and thereafter remains on the Leased Premises upon the expiration of the term
of this Lease, Lessor may determine that no tenancy of any duration shall be
created; that a tenancy shall exist and be deemed to continue for month to
month; or that Lessee has exercised its option to renew and extend as provided
by this Section and in such latter event both Lessor and Lessee shall be bound
by the terms of such renewal and extension.  If Lessor deems the tenancy to
continue for month to month it shall so continue at One and one-half (1  1/2)
times the monthly installment of Base Rent above provided and on the terms
herein expressed where applicable.

         SECTION 9.8.  ABANDONED PERSONAL PROPERTY AND LIENS:  At Lessor's
election and demand, Lessee shall remove all of Lessee's personal property from
the Leased Premises at the termination of the tenancy hereby created or at any
time Lessee vacates the Leased Premises or fails to occupy the same for 15
days, whichever first occurs.  In the event Lessee fails to remove Lessee's
stock-in-trade, trade fixtures, furniture, adornments, special equipment, and
all other items of personal property of Lessee located on or within the Leased
Premises and all Improvements installed by Lessee upon the Leased Premises as
may be required hereunder, Lessor shall have no obligation to store or protect
the same and may dispose of the same without notice to Lessee in any manner,
including without limitation, by:

                  gift of the same to charity;

                  disposal of the same as rubbish; and

                  sale of the same in any manner.

In the event such personal property is sold, Lessor shall be entitled to
compensation for the costs of such sale including, without limitation, an
amount equal to the value of Lessor's labor. If Lessee makes no claim to the
proceeds of any such sale within six (6) months thereof, all such proceeds
shall become the property of Lessor.

         SECTION 9.9.  LESSOR'S LIEN:  The rent hereunder and each and every
installment thereof, and all costs, reasonable attorneys' fees, or other
expenses which may be incurred by Lessor in enforcing the provisions of this
Lease, or on account of any delinquency of Lessee in carrying out the
provisions of this Lease, shall be and hereby are declared to constitute a
valid lien upon the interest of Lessee in this Lease and the stock-in-trade,
trade fixtures, furniture, adornments, special equipment, and all other items
of personal property of Lessee located on or within the Leased Premises and all
Improvements installed by





                                      19
<PAGE>   20

Lessee upon the Leased Premises.  Lessor is hereby authorized by Lessee, at
Lessor's expense, to cause this Lease, or any statement or other instrument in
respect to this Lease showing the interest of Lessor in the property of Lessee,
including Uniform Commercial Code Financing Statements to be filed or recorded
and refiled and rerecorded.  Lessee further grants Lessor the right to file such
statements without Lessee's signature.

         SECTION 9.10.  SUBORDINATION:  Lessor reserves the right to subject
and subordinate this Lease to the lien of any mortgage hereafter placed upon
the Leased Premises or the land and building of which the Leased Premises are a
part, provided that the Lease will only be subordinate if Lessee receives a
non-disturbance agreement.

         SECTION 9.11.  INDIANA RESPONSIBLE PROPERTY TRANSFER ACT:  If, during
the term of this Lease, Lessor transfers the Leased Premises, Lessee shall
provide such information required by the Indiana Responsible Property Transfer
Act ("Act"), Ind. Code  13-7-22.5-1, et seq., to enable Lessor to deliver the
environmental disclosure document for transfer of real property, as required by
the Act.

         SECTION 10.1.  ATTORNEYS' FEES AND COSTS:  If litigation occurs
between the parties, the successful party shall pay and discharge all
reasonable costs, attorney's fees and expenses that shall be made and incurred
by the successful party in enforcing the covenants and agreements of this
Lease, including the agreement to deliver possession for any reason herein
provided.

         SECTION 10.2.  FORCE MAJEURE:  If Lessor or Lessee is delayed or
prevented from the performance of any act required by this Lease by reason of
an act of God, strikes, lockouts, labor troubles, inability to procure
materials, restrictive governmental laws or regulations, or any other cause
without fault and beyond the reasonable control of Lessor, performance of such
act shall be excused for the period of the delay.  The performance of such act
shall be extended for a period equivalent to the period of such delay,
provided, however, that nothing in this Section shall excuse Lessor from the
prompt payment of any sum or charge required except as may be expressly
provided elsewhere in this Lease.

         SECTION 10.3.  ADDITIONAL DOCUMENTS:  Lessor agrees to assist and
cooperate in any application or petition to any governmental authority
necessary or convenient to obtain any permit, license, or approval of such
authority as needed for Lessee's Use and to sign any additional documents, as
landowner, necessary or convenient to such application or petition.  Such
assistance shall be without cost or expense to Lessor and shall not create any
obligation for the payment of any expense by Lessor.  Any such cost and expense
to be incurred by Lessor shall be paid in advance by Lessee.

number of counterparts and each such counterpart shall, for all purposes, be
deemed to be an original.
