will not exceed US$3,500.00 per year:

     A.   The premium of a fire insurance policy on the Leased Property
(including the Building and improvements thereof) with extended coverage,
including insurance against any loss or damage by fire and against any loss or
damage by lightning, explosion, hurricane and hail, airplanes, vehicles and
smoke, earthquake and/or volcanic eruption, strikes, riots and vandalism and any
other risks now or hereafter embraced by so called "Extended Coverage"

or LESSEE from becoming a co-insurer under the terms of the applicable policies,
but in any event in an amount not less than one hundred percent of the then
"full insurable value" (replacement value indicated in US$) of the Building and
improvements which exist on the Leased Property. For the purpose of this clause,
replacement value shall be deemed to be the cost of replacing the Building less
the cost of excavations, foundations, and footings and without any deductions
for physical depreciation of the Building. Such "full insurable value" shall be
determined from time to time, but not more frequently than once in every twelve
months, by mutual agreement of the parties. If the parties cannot reach an
agreement with respect to such determination on replacement value, LESSEE at its
expense may determine replacement value by hiring a licensed appraiser and
certified by a Mexican credit institution authorized for that purpose.

     B.   General public liability insurance, covering claims, demands and
actions for injury or death of any person, in an amount not less than
$500,000.00 currency of the United States of America; and for accidental injury
or death of more than one person from any one accident, and for any liability
arising from damages to property of third parties, with a limit of $100,000.00

actions arising from, related to, or connected with the use by LESSEE of the
Leased Property. LESSOR shall be named as additional insured under this policy.

     C.   Insurance against loss or damage by boiler (or compressor) malfunction
or by internal explosion by boiler (compressor), for any high pressure vessel
installed in the Building

<PAGE>

which is part of the Leased Property, in such amounts as LESSOR, from time to
time, reasonably requires; and

     D.   Rental interruption insurance, covering risk of loss of rentals due to
occurrence of any hazard set forth in this clause in an amount required to pay
the rent, taxes and insurance premiums then required hereunder for a twelve-
month period.

     LESSOR hereby waives its right of recovery against LESSEE for damages
caused by fire, explosion and other casualty to any of the Leased Property to
the extent that LESSOR makes recovery under insurance policies in effect at the
time of loss.  LESSEE hereby likewise waives its right of recovery against
LESSOR for damages caused by fire, explosion and other casualty to the Leased
Property if is covered by insurance policies in effect at the time of loss.
This provision does not extend, and the waiver does not apply, to any damages
suffered by either party hereto which are not covered by the insurance policies
above mentioned, or which are under the deductible thereof.

     The LESSOR and the LESSEE agree to use good faith efforts to have any and

                                   EXHIBIT C

                       FORM OF THE GUARANTY OF THE LEASE

     The undersigned ("Guarantor") absolutely and unconditionally guarantees the
full payment, performance and observance of all the rent, covenants, conditions,
and agreements provided to be performed and observed by SPECTRUM CONTROL DE
MEXICO, S.A. DE C.V. ("Lessee") in that certain Lease Contract (the "Lease")
dated effective as of March 15, 2000 between INDUSTRIAS DE AMERICA, S.A. DE C.V.
("Lessor") and Lessee relating to the Land and Building located at Boulevard
Zaragoza 2910, in the City of Juarez, State of Chihuahua, Mexico.

     The undersigned expressly agrees that its obligations hereunder shall not
be terminated, affected or impaired by reason of the granting by LESSOR of any
indulgences to LESSEE or by reason of the assertion against LESSEE of any of the
rights or remedies reserved to LESSOR pursuant to the provisions of said Lease
or by the release of LESSEE from any of LESSEE's obligations under said Lease by
operation of law or otherwise, the undersigned hereby waiving all suretyship
defenses.  The undersigned further covenants and agrees that this Guaranty shall
remain and continue in full force and effect as to any renewal, assignment,
modification or extension of the Lease whether or not the undersigned shall have
received any notice of or consented to such renewal, modification or extension.

     The undersigned further agrees that its liability hereunder shall be
primary, and that in any right to action which shall accrue to LESSOR under the
Lease, LESSOR, may at its option, proceed against the undersigned and LESSEE,
jointly and severally, and may proceed against the undersigned without having
commenced any action or having obtained any judgment against LESSEE; provided
however, that the undersigned shall have no liability to LESSOR unless and until
the undersigned shall receive notice of default by LESSEE and have been given
the same time period provided to LESSEE under the Lease to cure such default.

     It is agreed that the failure of LESSOR to insist in any one or more
instances upon strict performance or observance of any of the terms, provisions
or covenants of the Lease or to exercise any right therein contained shall not
be construed or deemed to be a waiver or relinquishment for the future of such
term, provision, covenant or right, but the same shall continue and remain in
full force and effect. Receipt by LESSOR of rent or other payments with
knowledge of the breach of any provision of the Lease shall not be deemed a
waiver of such breach.

     No assignment or other transfer of the Lease, or any interest therein,
shall operate to extinguish or diminish the liability of the undersigned
hereunder.

     The undersigned represents and warrants that (a) the undersigned is
authorized to execute

                                      -24-
<PAGE>

and deliver this Guaranty, (b) the person executing this Guaranty is authorized
to execute the same for and on behalf of the undersigned, (c) the undersigned
has all requisite power and authority to enter into this Guaranty, (d) neither
the execution or delivery of this Guaranty, nor the performance of the terms,
conditions or provisions of this Guaranty, constitute a default under, or result
in the creation of any lien pursuant to, any other agreement or instrument under
which the undersigned is obligated, and (e) at the time of execution and
delivery of this Guaranty, nothing exists to impair the effectiveness of the
liability of the undersigned to LESSOR hereunder, or to impair the immediate
taking effect of this Guaranty as the sole agreement between the undersigned and
LESSOR with respect to guaranteeing all of Company's obligations to LESSOR under
the Lease Agreement. Upon execution hereof the undersigned shall provide to
LESSOR certified copy of the resolutions authorizing the Guaranty.

     In the event LESSOR discounts, collaterally assigns or assigns the Lease
and the Guaranty to a bank or other lending institution (hereinafter referred to
as "Lender"), the undersigned upon written request, to the extent applicable and
true, shall furnish to Lender a letter stating that the undersigned acknowledges
receipt of notice of an assignment by LESSOR of the Guaranty; that the Guaranty
is in full force and effect; that no changes to the Guaranty as originally
executed have been made; that the undersigned will not enter into any
modification of the Guaranty without first obtaining Lender's prior written
approval; and provided that the LESSOR's notice to the undersigned includes an
irrevocable authorization and direction by LESSOR to pay all payments due under
the Lease to Lender, that all payment made thereafter shall be made to Lender or
its assigns in U.S. Dollars, at such times and at such places as directed by
Lender or its assigns.

     This Guaranty shall be irrevocable.

     The undersigned represents that the undersigned directly or indirectly
benefits from making this Guaranty.

     This Guaranty shall be governed by and construed in accordance with the
internal laws of the State of Texas excluding any principles of conflicts of
laws. In any action prosecuted by LESSOR for the interpretation and performance
of this Guaranty, Guarantor agrees to and hereby submits Guarantor to the
personal and subject matter jurisdiction of the Federal District Court of the
Western District of Texas, and/or the State Courts in El Paso, El Paso County,
Texas.  The undersigned expressly waives the right to any other jurisdiction
that Guarantor may have as a result of the undersigned's present or future
domicile, or due to any other cause whatsoever.

     The rights and remedies of LESSOR under this Guaranty, and the rights and
remedies of LESSOR created under the Lease or under applicable law, are
cumulative and may be exercised singly or concurrently, and the exercise of any
one or more of them will not be a waiver of any other.

                                      -25-

     This Guaranty is binding upon the undersigned and its legal representatives
and successors and shall inure to the benefit of LESSOR, its legal
representatives, successors and assigns, provided however that the undersigned
shall not assign its obligations hereunder.

     The whole of this Guaranty is set forth herein and there is no verbal or
other written agreement and no understanding or custom affecting the terms
hereof.  This Guaranty can be amended only by a written instrument specifically
referencing this Guaranty and executed by both parties hereto.

     Notwithstanding anything to the contrary set forth herein, the undersigned
shall have the benefit of any rights which the LESSEE may have pursuant to the
provisions of the Lease, and the liability of the undersigned hereunder shall in
no event exceed the liability of the LESSEE under the covenants, conditions, and
agreements provided to be performed and observed by the LESSEE under the terms
of the Lease.

     In Witness Whereof, this Guaranty is executed this March 16, 2000.
