                                    -3-

      (13) That no assent, express or implied by the Lessors, to any breach of
any of the Lessee's covenants shall be deemed to be a waiver of any succeeding
breach of the same covenant.

      Provided always that these presents are upon this condition that if the
Lessee or its representatives, successors or assigns, shall neglect or fail to
perform and observe any covenant herein contained which on the Lessee's part is
to be performed, or if their leasehold estate shall be taken in execution, or if
the Lessee shall be declared bankrupt or insolvent according to law or shall
make an assignment for the benefit of their creditors, then and in any case the
Lessors or those having the estate of the Lessors in the premises, lawfully may
immediately or at any time thereafter and without notice or demand, enter into
and upon the demised premises or any part thereof and repossess the same as if
of their former estate and expel the Lessee and those claiming under it and
remove Lessee's effect forcibly if necessary without being taken or deemed to be
guilty of any manner of trespass. And thereupon this demise shall absolutely
determine but without prejudice to any remedies which might otherwise be used by
the Lessors for arrears of rent or any breach of the Lessee's covenants herein
contained.

      Provided also that in case the demised premises or any part thereof shall
at any time during said term be destroyed or damaged by fire or other
unavoidable casualty so as to be unfit for occupancy and use and so the premises
cannot be rebuilt or restored by the Lessors within one (1) year thereafter,
then and in that case this demise shall terminate, but if the premises can be
rebuilt or restored within one (1) year, and if proceeds of insurance payable
for such casualty are sufficient therefor, the Lessors will at their own expense
and with due diligence so rebuild or restore the premises and Lessee shall
continue to pay the rents hereunder without abatement.

      Provided also that in case the whole or any part of the premises hereby
demised shall be taken by the City or State or other public authority for any
use, then this demise shall terminate from the time when such possession of the
whole or any part so taken shall be required for such public use and the rents
properly apportioned shall be paid up to that time; and such taking shall not be
deemed a breach of the Lessors' covenant for quiet enjoyment hereinbefore
contained.

      (14) Lessee covenants and agrees to pay all taxes due and payable and all
assessments hereafter levied during the term or extension thereof of this lease.

      (15) Each party hereto hereby waives all claims for recovery from the
other party for any loss or damage to any of its property insured under valid
and collectible insurance policies to the extent of any recovery collectible
under such insurance, subject to the limitation that this waiver shall apply
only when the fire and extended coverage policies of both parties contain a
clause to the effect this waiver shall not affect said policies or the right of
both parties to recover thereunder. Both parties agree that such insurance
policies will include such clause as long as the same is includable without
extra cost.

                                    -4-

      This lease shall be subject to and subordinate to the lien of any mortgage
or mortgages or deed or deeds of trust which at any time may be placed upon the
fee title to the premises above described; provided, however, that the rights of
the Lessee, its successors and assigns hereunder shall not be cut off or
affected by foreclosure of any such mortgage or mortgages or deed or deeds of
trust so long as the Lessee, its successors and assigns, shall not be in default
hereunder.

      Lessor hereby grants to Lessee an option to purchase the Leased Premises
for a stipulated and agreed upon sum of $1,389,000. The term of said purchase
option shall commence on the date hereof and shall expire on July 31, 1999. In
the event Lessee desires to exercise its option to purchase the Leased Premises,
Lessee shall notify Lessor in writing of Lessee's exercise of such purchase
option on or before January 31, 1999; otherwise, the purchase option shall be
null and void and of no further force or effect. In the event Lessee timely
exercises its option to purchase the Leased Premises, Lessor and Lessee agree to
cooperate with each other in good faith to close the purchase of the Leased
Premises within thirty (30) days following the date that Lessee notifies Lessor
in writing that Lessee has exercised its purchase option. The purchase option
shall cover the entire Leased Premises, including all improvements, structures,
buildings and fixtures, located therein or thereon, and all of Lessor's right,
title and interest in and to all easements and other appurtenances thereto, and
the same shall be conveyed by Lessor to Lessee by warranty deed and bills of
sale and assignments, with covenants of general warranty, free and clear of all
liens and encumbrances.

      Concurrently with the execution of this agreement, Lessor and Lessee agree
to execute and file of record in the appropriate public records of Winona
County, Minnesota, a Memorandum of Option specifying the leased premises and the
term of the option described in the preceding paragraph, in the form attached
hereto as "Exhibit A".

      IN WITNESS WHEREOF, the parties hereto have executed this agreement,
effective the day and year first above written.

                              AMENDMENT TO LEASE

      This Amendment to Lease (this "Amendment") is made and entered into on
this 30th day of July, 1996, by and between David H. Arnold and Muriel M.
Arnold, husband and wife, and Daniel M. Rukavina and Patricia A. Rukavina,
husband and wife (collectively, "Lessor"), and EMD Associates, Inc., a Minnesota
corporation ("Lessee").

      WHEREAS, Lessor and Lessee entered into a Lease Agreement dated July 30,
1996 (the "Lease"), whereby Lessor demised and let unto Lessee the premises
located at 4155 Theurer Boulevard, Goodview Minnesota, and legally described in
said Lease as Lots Four (4) and (5), Block One (1), record plat of Goodview
Industrial Park, for a term commencing September 1, 1996, and continuing until
August 31, 2006, and thereafter from year to year until terminated as provided
therein, for a net rent of $17,150 per month, subject to adjustment as provided
therein; and

      WHEREAS, the Lease remains in full force and effect; and

      WHEREAS, the parties have agreed that the legal description of the
premises was incorrectly described, and the parties desire to modify and amend
the Lease to correct the legal description of the premises covered by the Lease,
and to otherwise modify the Lease in other respects, all as more particularly
described herein;

      NOW, THEREFORE, in consideration of the premises, the mutual covenants
herein contained and other good and valuable consideration, the receipt and
sufficiency of all of which is hereby acknowledged and confessed, the parties
hereto hereby agree as follows:

      (16) The legal description of the premises described in the Lease was
incorrect and the parties hereby agree that the premises described in the Lease
shall be modified to be those certain premises located at 4155 Theurer
Boulevard, Goodview, Winona County, Minnesota, and legally described on Exhibit
A attached hereto and incorporated herein for all purposes.

      (17) In the event Lessor is unable to deliver the premises to Lessee free
and clear of all other tenancies, and with all of the prior tenant's property
removed therefrom, on or before September 1, 1996, then the term of the Lease
(and Lessee's obligations thereunder, including, without limitation, the
obligation to pay rent) shall not commence until such premises are delivered to
Lessee in the aforementioned condition. Notwithstanding the foregoing, however,
in the event Lessor is able to deliver the entire manufacturing portion of the
premises to Lessee prior to delivering the office portion of the premises to
Lessee, then Lessor and Lessee agree that the Lease shall commence (and Lessee's
obligations under the Lease, including the payment of rent) only with respect to
the manufacturing portion of the premises on the date that the entire
manufacturing portion of the premises is delivered to Lessee in the
aforementioned conditioned; provided, however, until the remainder of the
premises is delivered to Lessee, all rent and other charges payable under the

                                    -7-


Lease shall be prorated such that Lessee shall only be obligated to pay a
percentage thereof based upon the ratio that the square footage of the
manufacturing portion of the premises bears to the total square footage of the
manufacturing portion and the office portion of the premises. Notwithstanding
any of the foregoing or anything in the Lease to the contrary, Lessor covenants
and agrees to deliver the entirety of the premises to Lessee in the
aforementioned condition not later than September 30, 1996.

      (18) Except as amended herein, the said Lease shall be and remain in full
force and effect.

      IN WITNESS WHEREOF, the paries hereto have executed this Amendment,
effective July 30, 1996.
