         Seller.

         raw materials, work-in-process, finished goods, consigned goods, and

         by any party of any condition, or of any breach of any term contained
         in this Agreement, in any one or more instances, shall be deemed to be

         any breach of any other term.

         7.7. NO THIRD-PARTY BENEFICIARIES. The provisions of this Agreement are
         solely between and for the benefit of the two Parties, and do not inure
         to the benefit of, or confer rights upon, any third party, including,
         without limitation, any employee of the Parties.

         7.8. SEVERABILITY. The invalidity or unenforceability of any particular
         provision of this Agreement shall be construed in all respects as if
         the invalid or unenforceable provision were omitted. All provisions of
         this Agreement shall be enforced to the full extent permitted by law.

         7.9. HEADINGS. The headings of the sections of this Agreement have been
         inserted for convenience of reference only and shall not restrict or
         otherwise modify any of the terms or provisions of this Agreement.

         and enforced in accordance with the laws of the State of Minnesota as
         applicable to contracts made and to be performed in that state as to

                                    EXHIBIT C

                            EQUIPMENT LEASE AGREEMENT

         This Equipment Lease ("Lease") is entered into effective December 1,
2000, by and between Magstar Technologies, Inc., a Minnesota corporation
("Lessor"), and Reuter Manufacturing, Inc., a Minnesota corporation ("Lessee").

         1. LEASE. Lessor hereby lease to Lessee, and Lessee hereby leases and
hires from Lessor, upon the terms set forth herein all machinery, equipment,
vehicles and other property described in Exhibit A attached hereto (the
"Equipment")

         2. TERM. The term of this Agreement respecting each item of Equipment
commences on the date of this Agreement and expires 72 months following the date
of this Agreement.

         3. RENT. The rent for all of the Equipment, for the term of this
Agreement shall be a principal amount equal to $486,461 (the "Rent") which Rent
shall be payable in monthly installments of rent and interest of $4,512 per
month for the first six months, $8,100 per month for the next six months and
$8,988 per month for the last sixty months. Lessee shall pay Lessor each
installment of Rent in advance, on or before the 1st day of each month at the
offices of the Lessor, or to such other person and/or at such other place as
Lessor may from time to time designate in writing. In the event items in
addition to those specified in Exhibits A become Equipment, then any schedule
executed by the parties shall specify the additional amount to be paid as Rent
(and the additional monthly installment) in light of the additional items.

         4. USE. Lessee shall use the Equipment in a careful and proper manner
and shall comply with and conform to all national, state, municipal, and other
laws, ordinances and regulations relating to the possession, use or maintenance
of the Equipment. If at any time during the term hereof Lessor supplies Lessee
with labels, plates or other markings, stating that the Equipment is owned by
Lessor, Lessee shall affix and keep the same upon a prominent place on the
Equipment.

         5. LESSEE ACCEPTANCE; CONCLUSIVE PRESUMPTIONS. Lessee shall inspect the
Equipment within forty-eight (48) hours after receipt thereof. Unless Lessee
within said period of time gives written notice to Lessor, specifying any defect
in or other objection to the Equipment, Lessee agrees that it shall be
conclusively presumed, as between Lessor and Lessee, that Lessee has fully
inspected and acknowledged that the Equipment is in good condition and repair,
and that Lessee is satisfied with and has accepted the Equipment in good
condition and repair.

         6. LESSOR INSPECTION. Lessor shall, at any and all times during
Lessee"s normal business hours, have the right to enter the premises where the
Equipment is located for the purpose of inspecting the same or observing the use
thereof. Lessee shall not be permitted to remove any item of Equipment from the
location indicated on the Schedule without the prior written consent of Lessor.

         7. ALTERATIONS. Without the prior written consent of Lessor, which
consent shall not be unreasonably withheld, Lessee shall not make any
alterations, additions or improvements to the Equipment. Such permitted
alterations, additions or improvements may, at Lessee's option, be removed

<PAGE>


by Lessee upon the expiration or earlier termination of this Agreement if and
only if such removal may be accomplished without damage to the Equipment or
otherwise reducing its value below that which it would have been in the event no
such alterations, additions or improvements had been made.

         8. REPAIRS. Lessee, at its own cost and expense, shall keep the
Equipment in good repair, condition and working order, ordinary wear and tear
excepted, and shall furnish any and all parts, mechanisms and devices reasonably
required to keep the Equipment in good mechanical and working order.

         9. LOSS AND DAMAGE. Lessee hereby assumes and shall bear the entire
risk of loss and damage to the Equipment from any and every cause whatsoever. No
loss or damage to the Equipment or any part thereof shall impair any obligation
of Lessee under this Agreement which shall continue in full force and effect. In
the event of loss or damage of any kind whatever to any item of Equipment,
Lessee shall, at its own election, promptly place the same in good repair,
condition and working order, or replace the same with like Equipment in good
repair, condition and working order, or pay to Lessor an amount equal to the
fair market value of the Equipment so lost, damaged or destroyed, or pay over to
Lessor any insurance proceeds received on account of said loss or destruction.
Notwithstanding the foregoing, in no event shall the total of all payments under
this Lease for rent and for Equipment lost or destroyed be less than the total
scheduled rent payments.

         10. SURRENDER. Subject to the rights granted to Lessee pursuant to
paragraph 31 hereof, upon the expiration or earlier termination of this
Agreement, with respect to any item of Equipment, Lessee shall return the same
to Lessor in good repair, condition and working order, ordinary wear and tear
resulting from proper use thereof alone excepted, in the following manner as may
be specified by Lessor:

                  (a) By delivering such item of Equipment at Lessee's cost and
expense to such place as Lessor shall specify within the state of Minnesota; or

                  (b) By loading such item of Equipment at Lessee's cost and
expense on board such carrier as Lessor shall specify and shipping the same,
freight collect, to the destination designated by Lessor.

         Lessee shall not be required to return the Equipment if Lessee
exercises its option to purchase the Equipment at the end of the Lease term in
accordance with this Agreement.

         11. INSURANCE. Lessee shall keep the Equipment insured against all
risks of loss or damage by fire and such other risks as are covered by
endorsement commonly known as supplemental or extended coverage for not less
than the replacement value thereof. Lessee may effect such coverage under its
blanket policies. All such policies shall be written by companies presently
insuring the Lessee or other companies reasonably satisfactorily to the Lessor
and certificates showing such coverage to be in effect shall be furnished to the
Lessor upon request.

         12. TAXES. Lessee shall keep the Equipment free and clear of all
levies, liens and encumbrances and shall pay when due all fees, assessments,
charges and taxes (municipal, state and federal) which may now or hereafter be
imposed upon the ownership, leasing, renting, sale possession or

<PAGE>


use of the Equipment, excluding, however, all taxes on or measured by Lessor"s
income.

         13. LESSOR PAYMENT. In case of failure of Lessee to procure or maintain
said insurance or to pay said fees, assessments, charges and taxes, all as
hereinbefore specified, Lessor shall have the right, but shall not be obligated,
to effect such insurance, or pay said fees, assessments, charges and taxes, as
the case may be. In that event, the cost thereof shall be repayable to Lessor
with the next installment of Rent, and failure to repay the same shall carry
with it the same consequence, including interest at ten percent (10%) per annum,
as failure to pay any installment of Rent.

         14. REPRESENTATIONS AND WARRANTIES. Lessor represent and warrant that:

                  (a) Lessor is now and will at all times remain the absolute
and outright owners of the Equipment;

                  (b) Lessor has the power and authority to enter into this
Lease and to grant and fully perform the agreement to sell the Equipment upon
exercise of the purchase option

                  (c) This Lease does not conflict with any other agreement to
which Lessor is a party or of which Lessor has knowledge;

                  (d) This Lease is valid and binding upon Lessor;

                  (e) Lessor has not granted other options to purchase the
Equipment;

                  (f) Upon Lessee's exercise of the purchase option in
accordance with paragraph 31 of this Lease, Lessor will transfer the Equipment
to Lessee free and clear of all liens, claims and encumbrances of any kind or
nature;

                  (g) So long as Lessee is in compliance with the terms and
provisions of this Lease, Lessee shall peaceable and quietly have, hold and
enjoy the Equipment for the uses and purposes permitted under the Lease;

                  (h) Lessor shall indemnify, defend and hold harmless Lessee
from and against any claims asserted by third parties claiming ownership or
possessory rights to all or any of the Equipment except to the extent such
claims are the result of an act, omission or agreement of Lessee.

EXCEPT AS SET FORTH ABOVE, LESSOR MAKES NO WARRANTIES, EITHER EXPRESS OR
IMPLIED, AS TO ANY MATTER WHATSOEVER, INCLUDING, WITHOUT LIMITATION, THE
CONDITION OF THE EQUIPMENT, ITS MERCHANTABILITY OR ITS FITNESS FOR ANY
PARTICULAR PURPOSE.

         15. INDEMNITY. Lessee shall indemnify Lessor against, and hold Lessor
harmless from, any and all claims, actions, suits, proceedings, costs, expenses,
damages and liabilities, including reasonable attorneys' fees arising out of,
connected with, or resulting from Lessee's use, possession, delivery or return
of the Equipment. Each party agrees that it will give the other prompt notice of
the assertion of any such claim or the institution of any such action, suit or
proceeding.

<PAGE>


         16. DEFAULT BY LESSEE. If Lessee with regard to any item or items of
Equipment fails to pay any amount herein provided within thirty (30) days after
the same is due and payable, or if Lessee with regard to any item or items of
Equipment fails to observe, keep or perform any other provision of this Lease,
required to be observed, kept or performed by Lessee, and if Lessee fails to
remedy, cure or remove such failure in payment of such other failure in
observing, keeping or performing the provisions of this Lease within thirty (30)
days after receipt of written notice thereof from Lessor, Lessor shall have the
right to exercise any one or more of the following remedies: (a) To declare the
entire amount of rent hereunder immediately due and payable as to any or all
items of Equipment, without notice or demand to Lessee; (b) To sue for and
recover all rents, and other payments, then accrued or thereafter accruing with
respect to any or all items of Equipment; (c) To take possession of any or all
items of Equipment, without demand or notice, wherever same may be located,
without any court order or other process of law; (d) To terminate this Lease as
to any or all items of Equipment; or (e) To pursue any other remedy available to
Lessor at law or in equity. Lessee hereby waives any and all damages occasioned
by such taking of possession unless caused by Lessor"s gross negligence or
willful misconduct. Any such taking of possession shall not constitute a
termination of this Lease as to any or all items of Equipment unless Lessor
expressly so notifies Lessee in writing. Notwithstanding any said repossession,
or any other action which Lessor may take, Lessee shall be and remain liable for
the full performance of all obligations on the part of Lessee to be performed
under this Lease. All such remedies are cumulative, and may be exercised
concurrently or separately. In no event, however, shall these remedies be
exercised in such a manner that the Lessor recovers more than the balance of
rent and any other amounts payable by Lessee to Lessor hereunder, plus the fair
market value which the Equipment would have at the end of the initial term of
this Lease, discounted from the date of the default to the end of the initial
term of this Lease at a rate of nine percent (9%) per annum.

         17. DEFAULT BY LESSOR. In the event Lessee is deprived of the peaceable
and quiet enjoyment of the Equipment for the uses and purposes permitted under
the Lease or in the event upon Lessee's exercise of the purchase option in
accordance with paragraph 31 of this Lease, Lessor fail to transfer the
Equipment to Lessee free and clear of all liens, claims and encumbrances of any
kind or nature, provided Lessor are first given thirty (30) days written notice
and an opportunity to cure, Lessee may, at its sole option: (i) proceed by
appropriate court action, either at law or in equity, to enforce performance by
Lessor of the applicable covenants of this Lease, or (ii) file an action to
recover damages for breach hereof. Lessor shall be liable for all damages,
assessments, reductions in value, losses, claims, obligations, liabilities,
costs, charges and expenses of any kind or nature, including reasonable
attorneys' fees, costs, expenses and disbursements incurred by Lessee by reason
of the occurrence of the foregoing default or exercise of any of Lessee's
remedies with respect thereto. The remedies provided herein shall be cumulative.

         18. BANKRUPTCY. Neither this Agreement nor any interest therein is
assignable or transferable by operation of law. If any proceeding under the
United States Bankruptcy Code, as amended, is commenced by Lessee, or such an
action is commenced against Lessee and is not dismissed within sixty (60) days
after the commencement thereof, or if Lessee is adjudged insolvent, or if Lessee
makes any assignment for the benefit of its creditors, or if a writ of
attachment or execution is levied on any item or items of the Equipment and is
not released or satisfied within thirty (30) days thereafter, or if

<PAGE>


a receiver is appointed in any proceeding or action to which Lessee is a party
with authority to take possession or control of any item or items of the
Equipment (each of the foregoing is referred to as an "Event"), Lessor shall
have and may exercise any one or more of the remedies set forth in paragraph 16
hereof; and this Agreement shall, at the option of Lessor on notice to Lessee,
immediately terminate effective on the date of such Event and shall not be
treated as an asset of Lessee after the exercise of said option.

         19. LESSOR EXPENSES. Lessee shall pay Lessor all costs and expenses,
including reasonable attorneys' fees, incurred by Lessor in exercising any of
their rights or remedies hereunder or enforcing any of the terms, conditions, or
provisions hereof.

         20. ASSIGNMENT. Without the prior written consent of Lessor, which
consent shall be given or withheld in the Lessor's sole discretion, Lessee shall
not: (a) assign, transfer, pledge or hypothecate this Agreement, the Equipment
or any part thereof, or any interest therein; or, (b) sublet or lend the
Equipment or any part thereof, or permit the Equipment or any part thereof to be
used by anyone other than Lessee or Lessee's employees. Consent to any of the
foregoing prohibited acts applies only in the given instance; and is not a
consent to any subsequent like act by Lessee or any other person; provided,
however, that without such prior written consent but with notice to Lessor,
Lessee may assign this Agreement to any corporation or other legal entity into
which Lessee may merge or consolidate or which may acquire all or substantially
all of Lessee's assets, and may sublease any of the Equipment subject to this
Agreement to any subsidiary of Lessee or to Lessee's parent or any subsidiary of
Lessee's parent. No such permitted sublease shall operate to relieve Lessee of
its obligations hereunder which shall remain those of a principal and not a
guarantor.

         Subject always to the foregoing, this Agreement inures to the benefit
of, and is binding upon, the heirs, legatees, personal representatives,
successors and assigns of the parties hereto.

         21. LESSOR ASSIGNMENT. It is understood that Lessor, subject to the
terms of this Agreement, may assign this Agreement and/or mortgage the Equipment
and that said assignee may assign the same, and all rights of Lessor hereunder
may be assigned, pledged, mortgaged, transferred, or otherwise disposed of,
either in whole or in part, upon sixty (60) days notice to Lessee. Anything
herein contained to the contrary, Lessor shall not have the right to, and agree
that they will not, include in any such assignment any of Lessor' rights against
vendors, manufacturers or suppliers of any of the Equipment.

         22. OWNERSHIP OF EQUIPMENT. The Equipment is, and shall at all times be
and remain, the sole and exclusive property of Lessor; and Lessee shall have no
right, title or interest therein or thereto except as expressly set forth in
this Agreement.

         23. PERSONAL PROPERTY; UCC-1 FINANCING STATEMENT. The Equipment is, and
shall at all times be and remain, personal property notwithstanding that the
Equipment or any part thereof may now be, or hereafter become, in any manner
affixed or attached to, or imbedded in, or permanently resting upon, real
property or any building thereon, or attached in any manner to what is permanent
as by means of cement, plaster, nails, bolts, screws or otherwise, except as is
necessary or appropriate to operate the Equipment within manufacturer
specifications and instructions. Lessee agrees

<PAGE>


to execute a Form UCC-1 Financing Statement and any financing statements or
other documents reasonably required by Lessor to provide notice of this Lease.
Upon termination of this Lease, Lessor shall promptly execute and deliver such
documents as may reasonably be requested by Lessee to terminate such notice
filing.

         24. INTEREST. Should Lessee fail to pay any part of the Rent herein
reserved or any other sum required by Lessee to be paid to Lessor, within thirty
(30) days after the due date thereof, Lessee shall pay unto Lessor interest on
such delinquent payment from the expiration of said thirty (30) days until paid
at the rate of ten percent (10%) per annum.

         25. NON WAIVER. No covenant or condition of this Agreement can be
waived except in writing. Forbearance or indulgence by either party in any
regard whatsoever shall not constitute a waiver of the covenant or condition to
be performed by the other party to which the same may apply, and, until complete
performance of said covenant or condition, the other party shall be entitled to
invoke any remedy available to such party under this Agreement or by law or in
equity despite said forbearance or indulgence.

         26. ENTIRE AGREEMENT. This instrument constitutes the entire agreement
between Lessor and Lessee relating to and governing the lease and use of the
Equipment and it supersedes and replaces all prior agreements with respect
thereto. It shall not be amended, altered or changed except by a written
agreement signed by the parties hereto.

         27. NOTICES. Service of all notices under this Agreement shall be
sufficient if given personally delivered, telecopied or mailed via registered
mail to the party involved at its respective address hereinafter set forth, or
