FOR AND IN CONSIDERATION of the agreement by Eric Juan de Dios Flourie Geffroy,
Refugio Geffroy de Flourie, Elizabeth Pierret Pepita Flourie Geffroy and Edith
Elizabeth Cuquita Flourie Geffroy, (hereinafter referred to as Lessor) and
Electronica Lowrance de Mexico, S.A. de C.V., (herein after referred to as
Lessee) and further, to induce Lessor to enter into the Lease, and for other
good and valuable consideration, Lowrance Electronics, Inc., (hereinafter
referred to as Guarantor), a corporation established in the State of
_________________, U.S.A., unconditionally and irrevocably guarantees to Lessor
the full and prompt payment of all rentals, deposits, and other sums now or
hereafter becoming due and payable pursuant to the terms and provisions of the
Lease, and any and all renewals, extensions, amendments, or modifications of the
Lease ( all of the foregoing are collectively the "Obligations").

In the event any sums owing on any of the Obligation shall become due and are
unpaid by Lessee, Guarantor shall immediately pay all of such sums due Lessor
upon written notice from Lessor. In the event any of the terms, covenants or
provisions of the Lease are not performed promptly as therein provided,
Guarantor shall immediately so perform such terms, covenants, or provisions upon
written notice from Lessor.

It shall be necessary or required in order to enforce Guarantor's obligations
under this Lease Guaranty Agreement that Lessor shall have made demand for
payment or performance upon Lessee or any other person liable on or for the
Obligations for payment to Lessee or to any other person liable thereon or have
given notice to Lessee or any other person liable thereon of non-payment or
non-performance of said Obligations, or any other notice whatsoever. It shall
not be necessary or required, and Guarantor shall not be entitled to require,
that Lessor file suit. Guarantor waives any right to the benefit of or to
require or control application of any security or the proceeds of any security
now existing or hereafter obtained by Lessor as security for the Obligations.
Guarantor shall not have any recourse or action against Lessor by reason of any
action Lessor may take or omit to take in connection with security or any other
guaranty at any time existing thereof.

This is a guaranty of payment and not merely of collection. No renewal,
extension, or rearrangement of any other indulgence with respect to the
Obligations, or any part thereof, no release of or substitution for any security
or other guaranty now or hereafter held by Lessor for Obligations, or of any
part thereof, no failure to perfect any lien or security interest, no impairment
of collateral, or any security therefor or guaranty thereof or under this Lease
Guaranty Agreement shall in any manner impair the rights of Lessor or the
obligations and liability of Guarantor hereunder.

grace, notice of intent to accelerate maturity, notice that Lessor will not
accept late payments, presentment for payment, protest notice of pretest and of

taking any action with respect to this Lease Guaranty Agreement or said
Obligations or any property , rights , or interests which secure this Lease
Guaranty Agreement or said Obligations. Guarantor consents to and waives notice
of any and all renewals, extensions, and rearrangements of said Obligations and
to the release of all or any part of any property, rights, or interests which
secure this Lease Guaranty Agreement or said Obligations or any person liable
for any or the Obligations.

The obligations, covenants, agreements and duties of Guarantor under this Lease
Guaranty Agreement shall in no way be affected or impaired by (i) the
involuntary or involuntary bankruptcy, assignment for the benefit of credits,
reorganization or similar proceeding affecting Lessee or any of Lessee's assets,
or (ii) the release of Lessee from the performance or observance of any of the
agreements, covenants, terms or conditions contained in the documents evidencing
the Obligations by Lessee's bankruptcy, receivership, or similar protective
filing. This Lease Guaranty Agreement shall continue to be effective or be
reinstalled , as the case may be, if at any time any payment or performance of
any of the Obligations is rescinded or must be otherwise returned by Lessor in
connection with the insolvency, bankruptcy or reorganization of Lessee or
otherwise, all as though such payment had not been made.

Guarantor hereby irrevocably waives any and all claims or other rights which it
may now have or hereafter acquire against Lessee or any other guarantor of the
Obligations that arise from the existence, payment, performance or enforcement
of Guarantor's liabilities or Obligations under this Lease Guaranty Agreement ,
including, without limitation, any right of subrogation, reimbursement,
exoneration, contribution or indemnification , and any right to participate in

remedy.

Lessor and each and every other person who shall from time to time be or become
the owner , assignee or holder of the Lease or any of the Obligations hereby
guaranteed, and each and every reference herein to "Lessor" shall also include
and refer to each and every successor or assignee of Lessor, where the successor
or assignee is allowed under the lease, at any time holding or owing any part of
or interest in any part of the Lease or the Obligations hereby Guaranteed. This
Lease Guaranty Agreement shall be transferable, in whole or in part, by Lessor
and its assigns, with the same force and effect and to the same extent that the
Lease or the Obligations are transferable.

Any proceeding under this Lease Guaranty Agreement may be brought by Lessor as
to some, but less than all, Obligations, at Lessor's sole discretion, and any
such proceeding brought by Lessor with respect to some, but less than all,
Obligations shall not in any manner whatsoever affect, waive, diminish, or
impair the rights of Lessor to

thereafter institute proceeding as to any or all Obligations not therefore the
subject of any proceeding under this Lease Guaranty Agreement, either
simultaneously or serially , until all Obligations have been fully and finally
paid and discharged. The exercise of any right or remedy granted to or conferred
upon Lessor in this Lease Guaranty Agreement or in any instrument, document, or
other writing now or hereafter evidencing, securing, or otherwise pertaining to
said Obligations or this Lease Guaranty Agreement shall be wholly discretionary
with Lessor, and such right or remedy shall not in any manner affect, impair, or
diminish the obligations and liabilities of Guarantor or any person liable on
said Obligations, or constitute or be deemed a waiver of any such right or
remedy or any other past, present, or future right or remedy of Lessor.

all of the terms, provisions, covenants, warranties, waivers, and agreements
contained herein or in any writing evidencing, securing, or otherwise pertaining
to the Obligations shall be binding upon Guarantor and its successors, legal

the prevailing party and if this Lease Guaranty Agreement is enforced through
any judicial proceedings whatsoever.
