terms and conditions and for the consideration set forth in this Agreement, and
Employee is desirous of entering the employ of Employer pursuant to such terms
and conditions and for such consideration;

         NOW, THEREFORE, for and in consideration of the mutual promises,
covenants, and obligations contained herein, Employer and Employee agree as
follows:

ARTICLE 1: EMPLOYMENT AND DUTIES:

         1.1 Employer agrees to employ Employee, and Employee agrees to be

Employee's best efforts, to the business and affairs of Employer. Employee may
not engage, directly or indirectly, in any other business, investment, or
activity that interferes with Employee's performance of Employee's duties

to Employee during the employment relationship or that he learned while employed
by Employer that could reasonably be considered to have a detrimental effect on
the Employer's business.

         1.5 It is agreed that any direct or indirect interest in, connection
with, or benefit from any outside activities, particularly commercial
activities, which interest might in any way adversely affect Employer or any of
its Affiliates, involves a possible conflict of interest. In keeping with
Employee's fiduciary duties to Employer or any of its Affiliates, Employee
agrees that during the employment relationship Employee shall not knowingly
become involved in a conflict of interest with Employer or its Affiliates, or
upon discovery thereof, allow such a conflict to continue. Moreover, Employee
agrees that Employee shall disclose to the audit committee of Employer's board
of directors ("Employer's Board") any facts, which might involve such a conflict
               ----------------

as a whole.

person or entity in question, (ii) any officer, director or stockholder of such
person or entity in question; and (iii) any person or entity that, directly or
indirectly, controls, is controlled by, or is under common control with, any
officer, director or stockholder of such person or entity in question. For the
purposes of this definition, "control" (including, with correlative meaning, the
terms "controlled by" and "under common control with") as used with respect to
any person, shall mean the possession, directly or indirectly, of the power to
direct or cause the direction of the management and policies of such person or
entity, whether through the ownership of voting securities or by contract or

Exhibit A, subject to increase at the sole discretion of the Employer, which
shall be paid in installments in accordance with Employer's standard payroll
practice. Any calculation to be made under this Agreement, with respect to

made.

         2.2 While employed by Employer, subject to the sole approval and
discretion of Employer's Board, Employee may be allowed to participate in the

ARTICLE 3: TERMINATION PRIOR TO EXPIRATION OF TERM AND EFFECTS OF
SUCH TERMINATION:

         3.1 Notwithstanding any other provisions of this Agreement, Employer
shall have the right to terminate Employee's employment under this Agreement at
any time prior to the expiration of the Term for any of the following reasons:

                  a. For "cause" upon the good faith determination by Employer's
Board that "cause" exists for the termination of the employment relationship. As
used in this Section 3.1.a, the term "cause" shall mean (i) Employee's gross
negligence or willful misconduct in the performance of the duties and services
required of Employee pursuant to this Agreement, (ii) Employee's final
conviction of a felony, (iii) Employee's involvement in a conflict of interest
as referenced in Sections 1.4-1.5 for which Employer makes a determination to
terminate the employment of Employee which remains uncorrected for thirty (30)
days following written notice to Employee by Employer, or (iv) Employee's
material breach of any provision of this Agreement which remains uncorrected for
thirty (30) days following written notice to Employee by Employer of such
breach. It is expressly acknowledged and agreed that the decision as to whether
"cause" exists for termination of the employment by Employer is delegated solely
to Employer's Board for determination as to whether a reasonable basis for cause
exists;

                  b. for any other reason whatsoever, including termination
without cause, in the sole discretion of Employer, on ninety (90) days prior
written notice to Employee, subject to Employer's compliance with Section 3.5
hereof. Any material failure to comply with Section 3.5 shall be considered a
breach of this Agreement;

                  c. upon Employee's death; or

                  d. upon Employee's becoming disabled as to entitle Employee to
benefits under Employer's long-term disability plan or, if Employee is not
eligible to participate in such plan or if such plan is not available, then
Employee is permanently and totally unable to perform Employee's duties for
Employer as a result of any medically determinable physical or mental impairment
as supported by a written medical opinion to the foregoing effect by a physician
selected by Employer.

         The termination of Employee's employment by Employer prior to the
expiration of the Term shall constitute a "Termination for Cause" if made
                                           ---------------------
pursuant to Section 3.1.a, and the effect of such termination is specified in
Section 3.4. The termination of Employee's employment by Employer prior to the
expiration of the Term shall constitute an "Involuntary Termination" if
                                            -----------------------

                                       3

<PAGE>

made pursuant to Section 3.1.b, and the effect of such termination is specified
in Section 3.5. The effect of the employment relationship being terminated
pursuant to Section 3.1.c as a result of Employee's death is specified in
Section 3.7. The effect of the employment relationship being terminated pursuant
to Section 3.1.d as a result of the Employee becoming disabled is specified in
Section 3.8.

         3.2 Employee shall have the right to terminate the employment
relationship under this Agreement at any time prior to the expiration of the
Term for any other reason whatsoever, in the sole discretion of Employee, on
ninety (90) days prior written notice to Employer. The termination of Employee's
employment by Employee prior to the expiration of the Term shall constitute a
"Voluntary Termination" if made pursuant to Section 3.2; the effect of such
 ---------------------
termination is specified in Section 3.3.

         3.3 Upon a Voluntary Termination of the employment relationship by
Employee prior to expiration of the Term, all future compensation to which
Employee is entitled and all future benefits for which Employee is eligible,
with the exception of any and all statutory rights and benefits, shall cease and
terminate as of the date of termination. Employee shall be entitled to pro rata
salary through the date of such termination, but Employee shall not be entitled
to any bonuses, if applicable, not yet paid at the date of such termination.

         3.4 Upon a Termination for Cause of the employment relationship by
Employer prior to expiration of the Term, all future compensation to which
Employee is entitled and all future benefits for which Employee is eligible,
with the exception of any and all statutory rights and benefits, shall cease and
terminate as of the date of termination. Employee shall be entitled to pro rata
salary through the date of such termination, but Employee shall not be entitled
to any other bonuses, if applicable, not yet paid at the date of such
termination.

         3.5 Upon an Involuntary Termination of the employment relationship by
Employer prior to expiration of the Term, Employee shall be entitled, after such
termination, to receive his Monthly Base Salary through the remainder of the
Term, or for a period of 12 months commencing with the month following the month
of termination, whichever is longer, payable in installments in accordance with
Employer's standard payroll practices. All other future compensation to which
Employee is entitled and all future benefits for which Employee is eligible,
with the exception of any and all statutory rights and benefits, shall cease and
terminate as of the date of termination. Employee's rights under this Section
3.5 are Employee's sole and exclusive rights against Employer or its Affiliates,
and Employer's sole and exclusive liability to Employee under this Agreement, in
contract, tort, or otherwise, for any Involuntary Termination of the employment
relationship. Employee covenants not to sue or lodge any claim, demand or cause
of action against Employer for any sums for Involuntary Termination other than
those sums referred to in this Section 3.5. If Employee breaches this covenant,
Employer shall be entitled to recover from Employee all sums expended by
Employer (including costs and attorneys fees) in connection with such suit,
claim, demand or cause of action.

         3.6. Upon a Change of Control Termination prior to the expiration of
the Term, Employee shall be entitled in consideration of Employee's continuing
obligations hereunder after

                                       4

relationship during the Term and after the occurrence of a Change of Control for
any of the following reasons:

                           a) by Employee for "Good Reason" which shall mean
                                               -----------
         that (i) the Employee's Monthly Base Salary is reduced to an amount
         less than the Monthly Base Salary in effect for such Employee
         immediately prior to consummation of a Change of Control transaction,
         (ii) the benefits that Employee is entitled to receive immediately
         after a Change of Control are not substantially similar, in the
         aggregate, to the benefits that Employer is required to provide to
         Employee under this Agreement, or (iii) due to a Change of Control
         transaction, the Employee is required to relocate to a different
         metropolitan area; or

the date of such termination.

         3.9 In all cases, the compensation and benefits payable to Employee
under this Agreement upon termination of the employment relationship shall be
offset against any amounts to which Employee may otherwise be entitled under any
and all severance plans (including, without limitation, any severance plans with
a change of control feature), and policies of Employer or its Affiliates.

of the Term, such employment shall convert to a month-to-month relationship
terminable at any time by either Employer or Employee for any reason whatsoever,
with or without cause. Upon such termination of the employment relationship by
either Employer or Employee for any reason whatsoever, all future compensation
to which Employee is entitled and all future benefits for which Employee is
eligible shall cease and terminate. Upon the expiration of the Term, Employer

ARTICLE 5:  MISCELLANEOUS:

         5.1 For purposes of this Agreement the term "Change of Control" means
                                                      -----------------
(i) the Company merges or consolidates with any other entity and is not the
surviving entity (or survives only as the subsidiary of another entity), (ii)
the Company sells all or substantially all of its assets to any other person or
entity, (iii) the Company is dissolved, (iv) if any third person or entity
together with its Affiliates shall become, directly or indirectly, the
beneficial owner of more than 50% of the Voting Stock (as defined below) of the
Company, or (v) if, during such time as the Company has a class of Voting Stock
registered under the Securities Exchange Act of 1934, the individuals who
constituted the members of the Company's board of directors ("Incumbent Board")
upon the effective date of such registration cease for any reason to constitute
at least a majority thereof, provided that any person becoming a director whose
election or nomination for election by Company shareholders was approved by a
vote of at least eighty percent (80%) of the directors comprising the Incumbent
Board (either by the specific vote or approval of the proxy statement of the
Company in which such person is named as a nominee for director, without
objection to such a nomination) shall be, for purposes of this clause (v),
considered as though such person were a member of the Incumbent Board. "Voting
Stock" means all the outstanding shares of capital stock of Company entitled to
vote generally in elections for directors, considered as one class; provided,
however, that if Company has shares of Voting Stock entitled to more or less
than one vote for any such share, each reference to a proportion of shares of
Voting Stock shall be deemed to refer to such proportion of the votes entitled
to be cast by such shares.

         5.2 Employer and Employee shall refrain, both during the employment
relationship and after the employment relationship terminates, from publishing
any oral or written statements about the other party (which in the case of
Employer includes any of its subsidiaries or Affiliates, or any of such
entities' officers, employees, shareholders, agents or representatives) that are
slanderous, libelous, or defamatory; or that disclose private or confidential
information about the other party (which in the case of Employer includes any of
its subsidiaries or Affiliates, or any of such entities' business affairs,
officers, employees, shareholders, agents, or representatives); or that
constitute an intrusion into the seclusion or private lives of the other party
(which in the case of Employer includes any of its subsidiaries or Affiliates,
or such entities' officers, employees, shareholders, agents, or
representatives); or that place the other party (which in the case of Employer
includes any of its subsidiaries or Affiliates, or any of such entities' or its
officers, employees, shareholders, agents, or representatives) in a false light
before the public; or that constitute a misappropriation of the name or likeness
of the other party (which in the case of Employer includes any of its
subsidiaries or Affiliates, or any of such entities' or its officers, employees,
shareholders, agents, or representatives). The courts may enjoin a violation or
threatened violation of this prohibition. The rights afforded the parties under
this provision are in addition to any and all rights and remedies otherwise
afforded by law.

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.

Guarantor further waives notice of the acceptance of this guaranty and waives
grace, notice of intent to accelerate maturity, notice that Lessor will not
accept late payments, presentment for payment, protest notice of pretest and of
dishonor, and diligence en

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
any claim or remedy of Lessor against Lessee or any other guarantor of the
Obligations or any collateral which Lessor now has or hereafter acquires,
whether or not such right , claim or remedy arises in equity or under contract ,
statute or common law including without limitation, the right to take in receive
from Lessee, directly or indirectly, in cash or other property or by setoff or
in any other manner, payment or security on account of such right , claim or
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

                                       2

<PAGE>

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
