     3. CONSTRUCTION. LESSOR will construct for LESSEE, upon the agreed leased
premises, a building with the mechanicals and landscaping pertinent thereto, in
accordance with certain plans and specifications (Exhibit "A" attached)
therefore prepared by Nick Fullerton Architects PC & Schmit Construction,
Contractor, which bears the written approval of both LESSEE and LESSOR
(hereinafter referred to as the PROJECT). LESSOR agrees to complete the PROJECT
by October 15, 1993, strictly in accordance with the aforesaid plans and
specifications, unless LESSOR and LESSEE agree to changes in such plans and
specifications as they may occur during construction. The LESSOR agrees to
assume the cost incurred for the PROJECT including the cost of the land,
construction of the building and


   2

required landscaping. LESSOR further agrees to guarantee the quality of
workmanship and other materials as provided in the Construction Contract (see
Exhibit "A") for a period of one (1) year after completion, with the exception
of those items covered by a specific manufacturer's warranty may differ from
above.

     4.  TERM. The primary term of this lease shall commence on November 1,
1993, provided that LESSOR has completed the PROJECT and LESSEE has accepted the
PROJECT and shall continue for a period of ten (10) years thereafter, unless
sooner terminated or extended as hereinafter provided. LESSEE shall have and is
hereby granted a total of three (3) successive five (5) year options to extend
the term of this lease beyond the initial term, upon the same covenants and
conditions as herein provided, except as hereinafter specifically set forth. If
LESSEE shall elect to exercise one or more of such options, it shall do so by
giving LESSOR written notice at least ninety (90) days prior to the expiration
of the primary term or the then current extension, and in such notice LESSEE
shall state the date which it elects to extend the term.

     5.  RENT. LESSEE agrees to pay to LESSOR or its designee a monthly rental
of $11,500, payable in monthly installments during the term of this lease.

     (a) In the event the LESSEE shall exercise its options to extend the
primary term of this lease, the monthly rental during the first option period
shall be $12,650; the monthly rental during the second option period shall be
$13.250 and, the monthly rental during the third option period shall be $13,900.

     (b) All rental provided for herein shall be paid in advance on or before
the fifth (5th) day of each month (unless such rental shall be abated or
diminished as provided hereinafter).

charges used by it, including but not limited to gas, electricity, and water.



                                       2

     7.  TAXES. LESSEE agrees to be responsible for all taxes levied upon
personal property, including trade fixtures and inventory, not owned by LESSOR
and kept on leased premises. LESSEE agrees to pay all taxes and assessments,
including RID's OR SID's, levied against the land and building and improvements,
and, upon request, agrees to furnish LESSOR with receipts showing payment
thereof. LESSEE shall have the right to direct LESSOR'S vote for or against any
new SID's or RID's.

     8.  MAINTENANCE. LESSEE agrees to maintain in good repair the outside
walls, roof and floor of the building and the surface of the parking area,
sidewalks and driveways, as well as the structural soundness of the building,
and all underground gas, water and sewer pipes. LESSEE agrees to keep the inside
of the building in good repair including plumbing, electrical, wiring, air
conditioning and heating equipment and those parts of underground gas, water and
sewer pipes as are contained in or are directly beneath the floor of the
building, and paint the exterior walls and be responsible for all glass,
casualty damage, reasonable wear and tear expected.

     9.  HAZARDOUS SUBSTANCE. Except those as currently in use as listed in
Exhibit "B" Hazardous Chemical List, and those considered as common cleaning
products commercially available, LESSEE shall not use any hazardous or toxic
substances without prior written notice to LESSOR. Said notice shall identify
the substance to be used, the area in which the substance is to be used, the
manner in which the substance is to be stored and applied, and the plans to
dispose of any excess. LESSOR has the option of refusing to consent to such use,
storage or disposal of toxic substances, and LESSEE's failure to comply with
such decision shall constitute a default by LESSEE. All hazardous or toxic
materials shall be used strictly in accordance with all applicable laws, rules
and ordinances, and LESSEE shall not allow any hazardous or toxic waste into the
air, ground or water that is not in compliance with said laws or regulations.
LESSEE shall indemnify and hold LESSOR harmless from any claims, liability,
loss, cost or expense


                                       3

   4


(including but without limitation, attorney fees) resulting from hazardous or
toxic wastes placed on the property by LESSEE.

     10. ALTERATIONS. LESSEE shall not make any alterations involving structural
changes after the initial construction of the improvements on the property,
without securing LESSOR'S written consent, which shall not be unreasonably
withheld. Other alterations or additions, such as to signage and
non-weightbearing partitions, may be made by LESSEE in good workmanlike manner
without cost to LESSOR and without LESSOR'S permission. LESSEE shall permit no
liens to attach to the premises by virtue of alterations or additions by LESSEE.

     11. TRADE OR OTHER FIXTURES. LESSEE may install or cause to be installed
such equipment as reasonably necessary for the operation of its business. Such
equipment may be installed prior to acceptance of the improvements and shall
remain personal property, and title hereto shall continue in the owner thereof,
regardless of the manner in which same may be attached or affixed to the
premises. In the event such equipment is subject to a lien or title retention
instrument, the holder of such liens or title retention instrument, shall have
the right and be able to enforce the same as stated therein.

     12. BUILDING EXPANSION. The entire acreage described in paragraph 2 is
reserved for the present or future use of the LESSEE. Without the written
consent of the LESSEE the LESSOR shall not subdivide the property during the
term of this lease or any extension thereof. Should the LESSOR be unable or
unwilling to construct additional facilities as requested by the LESSEE during
the initial term of this lease or any extension thereof, LESSEE may exercise an
option to purchase the property as provided in paragraph 21.

     13. CASUALTY DAMAGE AND INSURANCE. With respect to the building to be
erected on the leased premises, the LESSEE shall procure and maintain in force,
at LESSEE'S expense, a standard fire and extended coverage insurance policy of
the type then commonly purchased by the owners of commercial buildings in the
same area in which the leased


                                       4

   5


premises are situated, in an amount not less than $1,000,000. In the event of
loss by reason of the perils covered under such insurance, proceeds of any
insurance allowance of settlement shall be made available to the LESSEE for the
use for the purpose of repairing, restoring and/or replacing such damaged
building to the extent of such insurance proceeds. If the building cannot be
used during such repairing, restoring or replacing, the rentals reserved to the
LESSOR shall be temporarily abated and the LESSEE shall cause the required
repairing, restoring or replacing to be completed as expeditiously as possible.
In the event of loss by reason of perils covered by said insurance in excess of
the face amount of said insurance policy or of a loss from perils not covered by
said insurance, LESSOR shall have the option of receiving any insurance proceeds
and, at LESSOR'S expense, repairing and restoring said premises to its original
condition, or leaving the premises unrepaired. If the LESSOR elects not to so
repair and restore said premises, then the LESSEE shall have the option to
receive the insurance proceeds, if any, and so repair and restore the premises
at the LESSEE'S expense. In the event that neither the LESSOR nor the LESSEE
elect to repair and report the premises as aforesaid, then the insurance
proceeds shall be payable to the LESSOR and this lease shall thereupon
terminate. The LESSEE agrees to have such insurance as is required to be
procured and maintained by the LESSEE issued in the name of the LESSOR with
LESSEE as an additional insured, with a loss payable to any mortgages designated
by the LESSOR, and to deliver to the LESSOR and the LESSOR'S mortgagor, if any,
appropriate evidence of the existence of such insurance, together with the said
premium receipts therefore, and to keep the same in effect and in full force and
effect throughout the entire term of this lease or extension or renewal thereof.

     14. LIABILITY INSURANCE. LESSEE agrees at LESSEE'S expense to maintain in
force continuously throughout the term of this lease and any extension thereof
public liability insurance covering the leased premises, with limits of ONE
MILLION DOLLARS ($1,000,000.00) for death or injury to one person; FIVE HUNDRED
THOUSAND DOLLARS ($500,000.00) for death or



                                       5

   6

injury to more than one person; and FIFTY THOUSAND DOLLARS ($50,000.00) for
property damage with a $2,000,000.00 COMBINED SINGLE LIMIT, and shall upon
written request of LESSOR, furnish LESSOR a certificate by the insurer that such
insurance is in force. The LESSOR shall be named as an additional insured in
such policies of insurance.

     15.  COMPLIANCE'S WITH LAWS. LESSEE will promptly comply with all
applicable and valid laws, ordinances, and regulations of Federal, State,
County, Municipal or other lawful authority pertaining to the use and occupancy
of the leased premises.

     16.  BANKRUPTCY. Should LESSEE make an assignment for the benefit of
creditors, or be adjudicated bankrupt, such action shall constitute a breach of
this lease for which LESSOR, at its option, may terminate all rights of LESSEE
or its successors in interest under this lease.

     17.  EMINENT DOMAIN. If all of the leased premises is taken under the power
of eminent domain or conveyed under threat of condemnation proceedings, or if
only a part of such premises is so taken or conveyed and LESSEE shall determine
that the remainder is inadequate or unsatisfactory for its purposes, which
determination shall not be arbitrarily or capriciously made, then in either
event, this lease shall terminate effective as of the date LESSEE is required to
give up the right to occupy or use any part of the leased premises. The
termination of this lease as above provided shall not operate to deprive LESSEE
of the right to make claim against the condemning authority for any damage
suffered by LESSEE, but LESSEE shall have no right to make any claim against
LESSOR because of any such termination. If this lease is not terminated as above
provided, LESSOR and LESSEE shall agree upon an equitable reduction of the
rental.

     17a. ARBITRATION. If the parties fail to agree upon such reduction within
sixty (60) days from the date of the final award or payment for the part of the
leased premises so taken or conveyed, LESSOR and LESSEE shall each choose one
arbitrator and the two arbitrators so chosen shall choose a third arbitrator.
The decision of any two of the arbitrators as to the rental



                                       6

   7

reduction, if any, shall be binding on LESSEE and LESSOR and any expense of the
arbitration shall be divided equally between LESSEE and LESSOR.

     18. ATTORNEY'S FEES. If suit is brought to enforce any covenant herein
contained, the parties hereto agree that the losing party shall pay the
prevailing party a reasonable attorney's fee, which shall be fixed by the court,
and court costs.

     19. DEFAULT. In the event LESSEE shall default in the payment of the
monthly rent as provided herein, LESSOR shall promptly so notify LESSEE in
writing, and failure of LESSEE to cure such default within twenty (20) days
after receipt of such notice shall, at the option of the LESSOR, work as a
forfeiture of this lease, or LESSOR may enforce performance in any manner
provided by law, and LESSOR'S agent or attorney shall have the right without
further notice or demand to re-enter and remove all persons from LESSOR'S
property without being deemed guilty of any manner of trespass and without
prejudice to any remedies for arrears of rent or breach of covenant, or LESSOR'S
agent or attorney may resume possession of the property and relet the same for
the remainder of the term at the best rental such agent or attorney can obtain
for the account of LESSEE, who shall pay any deficiency, and LESSOR shall have a
lien as security for such rental upon the fixtures and equipment belonging to
LESSEE which are on the demised premises. In the event LESSEE shall default in
the performance of any of the terms or provisions of this lease other than the
payment of monthly rent, LESSOR shall promptly so notify LESSEE in writing. If
LESSEE shall fail to cure default within twenty (20) days after receipt of such
notice, or if the default is one of such character as to require more than
twenty (20) days to cure and LESSEE shall fail to commence to do so within
twenty (20) days after receipt of such notice and thereafter diligently proceed
to cure such default, then in either such event, LESSOR may cure such default
and such expense shall be added to the rent otherwise due, but any such default
shall not work as a forfeiture of this lease.


                                       7

   8


     In the event LESSOR shall default in the performance of any of the terms or
provisions of this lease, LESSEE shall so promptly notify LESSOR in writing. If
LESSOR shall fail to cure such default within twenty (20) days after receipt of
such notice, or if the default is of such character as to require more than
twenty (20) days to cure and LESSOR shall fail to commence to do so within
twenty (20) days after receipt of such notice and thereafter diligently proceed
to cure such default, then, in either such event LESSEE may cure such default
and such expense shall be deducted from the rent otherwise due or cancel and
terminate this lease.


     20. RIGHT OF FIRST REFUSAL. If during the term of this lease, or any
extension thereof, LESSOR shall receive a bona fide offer to purchase the
demised premises, which offer is acceptable to LESSOR, LESSOR agrees that LESSEE
shall have and is hereby granted an option to purchase the demised property upon
the same terms and provisions. LESSOR agrees immediately after receipt of such
an offer to give LESSEE notice in writing of the terms and provisions thereof,
and that LESSEE may exercise its option to purchase said property at any time
within twenty (20) days after such notice is received by LESSEE. If LESSEE shall
elect to exercise such option it shall do so by giving written notice to LESSOR
within such twenty (20) day period and a contract of sale shall be executed by
the parties and title closed within a reasonable time thereafter. The failure of
LESSEE to exercise the option provided in this article shall in no way relieve
or release LESSOR or its assigns from the terms and effect of the option granted
in paragraph 21.

     21. OPTION TO PURCHASE. Any time after the tenth (10th) lease year, or
earlier as provided in paragraph 12, by notification to LESSOR of LESSEE'S
intentions, LESSEE may exercise an option to purchase the property at a price to
be determined by the average of two MAI appraisals, but in no event may the
purchase price be less than eleven (11) times the annual rental at the time the
option is exercised; provided, however, that written notice of the exercise of
said option, accompanied by an earnest money deposit of TWENTY THOUSAND DOLLARS
($20,000.00) must be given to LESSOR within sixty (60) days of exercise of the
option. Upon



                                       8

   9


receipt of said notice and earnest money by LESSOR, the parties shall execute an
agreement to consummate said sale and the sale shall be closed within a
reasonable time thereafter, but, in all events, not later than one hundred
twenty (120) days of the notice of exercise of the option. Rent is to be
apportioned to date of closing.

     22. LESSOR'S COVENANTS. LESSOR covenants that it has good and marketable
title to the demised premises in fee simple absolute. In the event LESSEE
exercises its option to purchase as described above, LESSOR shall convey the
premises free and clear of all encumbrances except right-of-way, federal patents
and mineral reservations, easements, and building and use restrictions of
record.

     23. QUIET ENJOYMENT. That LESSEE upon paying the rent and performing the
covenants and agreements of this lease shall quietly have, hold and enjoy the
demised premises and all rights granted LESSEE in this lease during the term
thereof and extensions thereto, if any.

     24. SUBORDINATION. LESSEE hereby agrees that its lease-hold interest
hereunder is subordinate to any mortgages now on, or hereafter to be placed on
the premises leased hereunder; provided, as a condition precedent to such
subordination, each such mortgage shall expressly covenant or each mortgage
shall expressly provide that so long as the LESSEE is not in default under said
LEASE AGREEMENT, the LESSEE'S quiet possession of the portion of the premises
leased hereunder shall remain undisturbed, on the terms and conditions stated
herein, whether or not the mortgage is in default and notwithstanding and
foreclosure or other action brought by the holder of the mortgage in connection
therewith.

     25. ASSIGNMENT AND SUBLETTING. LESSEE shall have the right to assign or
sublease the whole or any part of the demised premises, provided that any
assignment or sublease shall be subject to all of the terms and conditions of
this lease and that LESSEE shall remain primarily liable for the payment of the
rent and the performance of the terms and conditions of this lease, unless
LESSOR shall agree otherwise.
