machinery that Tenant may place in or upon the Premises during its occupancy
thereof and any addition or improvement not intended as a fixture as provided
above, shall be, and remain at all times, personal property, whether affixed to

reasonable vehicular and pedestrian access for Tenant, Tenant's tractors,

affected, a proportionate and equitable reduction or abatement of rent shall be
made until such access is re-established.

         8.2. Tenant Maintenance. Except as otherwise expressly provided herein,
Tenant shall be responsible for the customary and routine repair and maintenance
(excluding capital improvements, replacements or alterations) of the Premises.

Such entry by Landlord shall be under the supervision of Tenant. Landlord shall

business operations.

         11.3. Impairment. Landlord acknowledges that the visibility of the
Premises is critical to the successful operation of Tenant's business. Landlord
agrees that during the Term of this Lease, or any renewal or extension hereof,
it will not materially impair the visibility of the Premises as it exists on the

private drives that provide access to the Land without the prior written consent
of Tenant.

         11.4. Temporary Obstructions. In the event access to the Premises or
visibility of Tenant's signage and/or windows is temporarily impaired, due to
Landlord's maintenance or repairs to the Land, any improvements of which the
Premises is a part, parking lots, public roadways or other ways of access to the
Premises, then the rent and all other charges payable under this Lease shall be
equitably adjusted, or abated, for the period of such temporary impairment.

12.      PARKING: Landlord represents that Tenant shall be entitled to the use
of not fewer than 150 parking spaces in the existing parking lot on the Land,
plus the Reserved Spaces. During the renewal Term(s) Landlord reserves the right
to designate the location of the 150 spaces in the vicinity of the northwest
side of the Building. Until such designation is made, Tenant shall have access
to all parking spaces. There shall be no additional charge for Tenant's parking

                13.2.1. Commercial general liability insurance issued by one or
more insurance carriers or self-insurance, insuring against liability for injury
to or death of persons and loss of or damage to property arising out of any
negligent act or omission of Landlord, its agents, contractors or employees.
Such insurance shall name Tenant as an additional insured, shall contain a
contractual liability endorsement, shall be on an "occurrence" basis and shall
provide aggregate limits of not less than $2,000,000 and per-occurrence limits
of not less than $1,000,000. Landlord is not responsible for maintaining

                13.2.2. "All risk" property damage insurance issued by one or
more insurance carriers covering the Premises to the extent of their full
replacement value exclusive of foundation and excavation costs. Tenant agrees to
reimburse Landlord for such insurance premiums for the "all risk" property
damage insurance within 30 days after receipt of written request therefrom from
Landlord, together with a copy of the receipt evidencing payment from the
insurance carrier. If such premiums shall cover a period of time prior to or
after the expiration of the term of this Lease Tenant's share of such premiums
shall be equitably prorated to cover only the period of time during which this
Lease is in effect.

         13.3. Insurance Certificates. Upon written request of either party
hereto, Landlord or Tenant, as the case may be, shall deliver to the requesting
party either proof of self-insurance or certificates issued by their respective
insurance carriers for each policy of insurance required to be maintained

indemnify and hold harmless Tenant from and against any and all claims, actions,
damages, liability and expense (including reasonable attorneys' fees and
expenses) in connection with loss of life, personal injury and/or damage to
property occasioned by any act or omission of Landlord, its agents, contractors,
employees or invitees. The foregoing indemnification shall not be deemed a
waiver of Landlord's sovereign immunity. The scope of Landlord's indemnification
of Tenant shall not exceed the extent permitted by Missouri law, including under
ss. 537.600, Mo. Rev. Stat. (1986). Tenant hereby releases and agrees to defend,
indemnify and hold harmless Landlord from and against any and all claims,
actions, damages, liability and expense (including reasonable 



                                       6
<PAGE>   8

attorneys' fees and expenses) in connection with loss of life, personal injury
and/or damage to property occasioned by any act or omission of Tenant, its
agents, contractors, employees, or invitees. The provisions of this Section 14
shall survive the expiration or earlier termination of this Lease.

15.      MUTUAL SUBROGATION: Landlord and Tenant hereby mutually release each
other from liability for any loss such party is required to insure against
hereunder for property loss or damage, including without limitation, fire,
extended coverage and other property insurance policies and hereby waive their
respective rights of recovery against each other for any such loss including any
insurance deductible amount. Each party shall obtain any special endorsements,
if required by its insurers, to evidence compliance with the aforementioned
waiver.

16.      DAMAGE OR DESTRUCTION: In the event that the Premises shall be damaged
or destroyed by fire or other casualty and neither Landlord nor Tenant elects to
terminate this Lease as hereinafter provided, Landlord shall proceed with
reasonable diligence and at its sole cost and expense to rebuild and repair the
Premises.

         16.1. Termination Rights. Notwithstanding anything contained herein to
the contrary, (i) if the Premises shall be destroyed or are damaged to such an
extent that in Tenant's reasonable judgment it cannot conduct its business in
the Premises in the manner conducted prior to the casualty (thereby triggering
Section 16.2 below), and if said damage cannot be repaired within ninety (90)
days from the date of casualty, then this Lease may be terminated by either
Landlord or Tenant by giving written notice to the other within thirty (30) days
after the occurrence of such casualty; or (ii) if Landlord fails to proceed
diligently to complete the repairs, or should Landlord fail to complete any
repairs within ninety (90) days of the date of casualty and the unrepaired
damage prevents Tenant from being able to conduct its business in the Premises
in the manner conducted prior to the casualty, Tenant may terminate the Lease at
any time within thirty (30) days after the expiration of such ninety (90) day
period. Upon Tenant's request, Landlord promptly shall provide Tenant with
documentation confirming that the damage to the Premises can be repaired within
said (90) ninety day period.

         16.2. Discontinuation and Abatement. If so much of the Premises shall
be damaged so that in Tenant's reasonable judgment it is unable to conduct its
business in the Premises in the manner conducted prior to the casualty, then
Tenant may discontinue the conduct of business in the Premises and all rent
shall abate until the earlier to occur of (i) the date on which such damage
shall be completely repaired, or (ii) the date on which Tenant resumes
conducting business in the Premises. If rent abates in accordance with this
Section 16.2., every other charge payable by Tenant to Landlord shall abate
also.

         16.3. Surrender. If the Lease is terminated in accordance with Section
16.1. hereof, Tenant shall, after promptly removing its property therefrom,
surrender the Premises to Landlord, shall pay rent to the date of such
destruction or damage and shall not be liable for any obligation accruing after
such damage or destruction. Landlord shall promptly refund to Tenant any prepaid
rental or other prepaid charges attributable to the period of time after the
date of such destruction or damage.

<PAGE>   9

         16.4. Slight Damage. If the Premises are slightly damaged by fire or
other casualty but said damage or the repair of such damage does not or will not
interfere with Tenant's conduct of its business, or otherwise render the
Premises or any part thereof untenantable, then Landlord shall promptly proceed
to repair the damage as provided above and monthly rent shall not abate but
Tenant shall continue to pay rent as provided herein.

17.      CONDEMNATION: In the event the entire Premises or a substantial portion
of the Premises should be taken for any public or quasi-public use under any
governmental law, ordinance or regulation or by right of eminent domain or by
private purchase in lieu thereof, this Lease shall terminate and expire as of
the date of such taking. Tenant shall have the right to recover any damages
suffered or sustained by Tenant as a result of taking only the property which
belongs to Tenant and any moving expenses or other award available to Tenant,
but Tenant shall have no claim or right to any portion of the amount that may be
awarded as damages or paid as a result of such taking for the loss of any part
of Tenant's leasehold interest. In the event that the remainder is suitable for
the uses authorized herein, subject to the approval of Tenant, this Lease shall
remain in full force and effect; provided, however, that rental payments
hereunder shall be proportionately reduced according to the nature and extent of
the deprivation to Tenant. Should Tenant elect to continue this Lease in effect,
Landlord shall proceed to repair the Premises and return them to suitable
condition for Tenant's continued occupancy hereunder.

connection with any toxic waste, hazardous materials, petroleum or petroleum
by-products or underground/aboveground storage tank contamination on, under or
about the Premises, except for contamination on, under or about the Premises
caused by Tenant in its use of the Premises during the Term of this Lease.
Landlord's obligations under this Section shall survive the expiration or
earlier termination of this Lease. The foregoing indemnification shall not be
deemed a waiver of Landlord's sovereign immunity. The scope of Landlord's
indemnification of Tenant shall not exceed the extent permitted by Missouri law,
including under ss. 537.600, Mo. Rev. Stat. (1986).

         18.2. Tenant Indemnity. Tenant hereby releases and agrees to indemnify,
defend and hold harmless Landlord from and against any and all claims, actions,
damages, liability and expense (including reasonable attorneys' fees and costs)
arising at any time whatsoever under any and all Federal, State, and/or local
laws regulations, ordinances or administrative orders, in connection with any
release of any toxic waste, hazardous materials, petroleum or petroleum
by-products or underground or aboveground storage tank contamination on, under
or about the Premises caused by Tenant in its use of the Premises during the

19.      SUBORDINATION: Tenant will, upon request by Landlord, subject and
subordinate this Lease to any and all mortgages and deeds of trust now existing
or hereafter placed on the Land; provided, however, that such subordination
shall be upon the express condition that this Lease shall be recognized by the
mortgagee or trustee under the mortgage or deed of trust and that the rights of
Tenant hereunder shall remain in full force and effect during the Term of this
Lease so long as Tenant is not in default under this Lease. Subject to receipt
of such recognition and agreement not to disturb Tenant, Tenant agrees that this
Lease shall remain in full force and effect notwithstanding any default or
foreclosure under any such mortgage or deed of trust. Tenant will, upon request
by Landlord, execute and deliver to Landlord instrument(s) in recordable form
reasonably required to give effect to the provisions of this Section. Landlord
will, upon request by Tenant, cause to be executed and delivered to Tenant
instrument(s) in recordable form reasonably required to effect the recognition
of Tenant's rights hereunder by the holders of all such mortgages and deeds of
trust whether or not Tenant has been requested to subordinate this Lease to such
mortgages or deeds of trust. Tenant may record a memorandum of this Lease in the
form attached hereto as Exhibit D, which Landlord shall execute at Tenant's
request.

20.      ASSIGNMENT AND SUBLETTING: Tenant may not assign this Lease or sublet
the Premises or any interest herein without written consent of Landlord, which
shall not be unreasonably withheld or delayed. Landlord may assign or convey its
rights under this Lease upon written notice to Tenant.

21.      LIENS: Tenant shall keep the Premises free from any liens arising out
of any work performed, materials furnished or obligations incurred by or on
behalf of Tenant. If, because of any act or omission of Tenant, any mechanic's
lien or other lien shall be filed against Landlord or against the Premises,
Tenant will protect, indemnify and save harmless Landlord from and in respect to
any and all such liens.

22.      TENANT DEFAULT:

         22.1. Termination. Any failure on the part of Tenant to comply with any
of the terms of this Lease shall, at the option of Landlord, work a termination
of the Lease whereupon Landlord, its agents or attorney, shall have the right to
enter the Premises and remove all persons therefrom; provided only that Landlord
shall first give written notice thirty (30) days in advance of any lease
termination, or such other time period required by applicable law, whichever is
longer, and during said period Tenant shall have the right to commence whatever
action may be necessary to correct its default, and thereafter diligently
proceed to cure such default, and having done so may continue its occupancy
under the terms hereof. If, however, termination occurs, Tenant shall not be
liable for any obligations accruing after the date of termination.

         22.2. Re-Entry. Landlord may, however, in lieu of termination, re-enter
the Premises and take possession thereof, and Tenant shall remain liable for all
rent and other charges to be paid by Tenant hereunder, in which event Landlord
shall use its best efforts to relet the Premises for the account of Tenant for
the maximum possible rental. Should Landlord relet the Premises or any portion
thereof, Tenant shall be liable to Landlord, and shall pay as it becomes due,
the amount of 



                                       9
<PAGE>   11

any deficiency between the amount of rental received by Landlord and the amount

23.      LANDLORD DEFAULT. In the event Landlord shall default in the
performance of any of the provisions of this Lease, Tenant shall so notify
Landlord. If Landlord shall fail to correct such default within thirty (30) days
after notice of such default, or if the default is of such character as to
require more than thirty (30) days to correct after notice is given and Landlord
does not thereafter diligently proceed to cure such default, then Tenant may
either terminate this Lease and not be liable for any obligations accruing
thereafter, or cure such default. Any expense for curing Landlord's default may
be deducted by Tenant from the rent otherwise due, and the balance due, after
such deduction, shall be a claim due Tenant by Landlord.

24.      WAIVER: The failure of Landlord or Tenant to insist upon prompt and
strict performance of any of the terms, conditions or undertakings of this
Lease, or to exercise any right herein conferred, in any one or more instances,
except as to the option to extend or renew the term, shall not be construed as a
waiver of the same or any other term, condition, undertaking, right or option.

25.      NOTICES: Any notices or other communications required or permitted by
this Lease shall be in writing and delivered personally or by messenger or a
nationally recognized overnight courier service, or alternatively, shall be sent
by United States first class mail, postage prepaid, addressed to the parties
hereto at the addresses as set out below, or at such other addresses as they
