"Effective   Date")   between  BOATRACS,   INC.,   a   California
corporation  (the "Company"), having an address  for  notices  at
6440  Lusk  Blvd., Suite D-201, San Diego, California  92121-2758
and  CHARLES  J. DROBNY, JR., ("Drobny"), having an  address  for
notices  at 2457 Summerwood Drive, Gulfport, MS 39507, who  agree
as follows:

     1.   Hiring.  The Company hereby hires Drobny as, and Drobny
hereby   agrees   to  act  as  Vice  President   of   Application
Development.   The  Company and Drobny intend to  enter  into  an
employer-employee  relationship, subject to  the  terms  of  this
Agreement,  based  upon  Drobny's ability  to  design  and  build
integrated  information and communication systems in  the  marine
industry  and  other related technical skills  and  further  upon
Drobny's  ability to expand and develop the Company's ability  to
offer its customers integrated marine information systems.

     2.   Duties.  Drobny shall faithfully and diligently perform
the  duties  described on attached Exhibit A  and  the  following
described  duties  on a full-time basis:  (a)  Devoting  Drobny's
entire productive time, ability and attention to the business  of
the  Company; and (b) Performing such other duties as  the  Chief
Executive Officer and President of the Company (the "CEO"), shall
from  time  to time specify that are consistent with  the  duties
normally performed by an employee in Drobny's position.

     3.  Base Compensation.
     
          3.1.  Drobny's total compensation ("Base Compensation")
under  this  Agreement, prorated for any partial year,  shall  be
$150,000.00 per year commencing on the Effective Date and  ending
on  the  second  anniversary of the Effective  Date  (the  "First
Half"), and $180,000.00 per year commencing on the expiration  of
the First Half and continuing until the fourth anniversary of the
term   of   this  Agreement  (the  "Second  Half").    The   Base
Compensation  shall  be  payable biweekly  in  arrears  from  the
Effective Date, in accordance with and at the same times  as  the
Company's ordinary payroll procedures.
          
          3.2.   During  the  First  Half,  Drobny  may,  at  his
election,  receive up to $30,000.00 per year of Base Compensation
in  the  form  of  shares  of  the Company's  common  stock  (the
"Stock").   During the Second Half, Drobny may, at his  election,
receive  up  to $60,000.00 per year of Base Compensation  in  the
form of Stock.  Drobny may exercise such option, with respect  to
any  particular semi-annual period (defined as January 1-June  30
and  July 1-December 31), by written notice to the Company on  or
before  5  days  before the beginning of such semi-annual  period
(such  exercise,  an "Election"). Such notice will  specify  that
portion  of  his  Base Compensation for the upcoming  semi-annual
period  that Drobny elects to receive in the form of  Stock.  The
value of Stock for purposes of this Paragraph shall be determined
as follows:
     
                (i)   If  the Stock is not at the time listed  or
admitted  to trading on any stock exchange but is traded  in  the
over-the-counter  market,  the fair market  value  shall  be  the
average mean between the highest bid and lowest asked prices (or,
if  such information is available, the closing selling prices) of
one  share of the Stock in the over-the-counter market,  as  such
prices  are  reported by the National Association  of  Securities
Dealers through its NASDAQ system or any successor system, on the
first  three trading days of the semi-annual period to which  the
Election relates.  If there are no reported bid and asked  prices
(or closing selling prices) for the Stock on any of the dates  in
question, then the average mean between the highest bid price and
lowest  asked prices (or the closing selling price) on  the  last
three  preceding dates for which such quotations exist  shall  be
determinative of fair market value.
     
                (ii)  If  the  Stock  is at the  time  listed  or
admitted  to trading on any stock exchange, then the fair  market
value shall be the average closing selling price of one share  of
Stock  on the first three trading days of the semi-annual  period
to  which  the Election relates, on the stock exchange determined
by  the  Company, in its reasonable discretion, to be the primary
market  for the Stock, as such price is officially quoted in  the
composite tape of transactions on such exchange.  If there is  no
reported sale of Stock on such exchange on the dates in question,
then  the fair market value shall be the average closing  selling
prices  on  the  exchange on the last three preceding  dates  for
which such quotations exist.
     
     4.    Benefits.   Drobny shall be entitled to the  following
benefits during the term of this Agreement:

          4.1.   Vacation benefits generally available  to  other
executives  of  the  Company of comparable  seniority  and  rank,
accrued  over  the  course of each year in  accordance  with  the
Company's policy.

          4.2.  Reimbursement for reasonable expenses incurred in
the  proper  performance of Drobny's duties under this  Agreement
and in accordance and consistent with the Company's policy.

          4.3.   Inclusion in the Company's medical plan for  the
Company's other employees.

          4.4.    All  benefits  generally  available  to   other
employees  of  the  Company, including without limitation  profit
sharing  benefits generally made available to other employees  of
Drobny's rank and seniority.
          
          4.5.   Reasonable  moving expenses  in  the  event  the
Company   requires  Drobny  to  relocate  his  residence  outside
Gulfport, Mississippi.
          
     5.   Term.   The term of this Agreement shall  be  four  (4)
years,  commencing on the Effective Date and ending on the fourth
anniversary of the Effective Date, unless terminated  earlier  in
accordance with the terms hereof.

     6.   Termination.  At any time that Good Cause  (as  defined
below)  exists  or has arisen, the Company may, at its  election,
terminate  this  Agreement upon 3 days written  notice.   In  the
event  of  such  Good  Cause  termination,  Drobny  may,  at  his
election,  appeal such termination to the Board of  Directors  of
the  Company, whose determination shall be final and binding. For
purposes of this Agreement, "Good Cause" shall mean the existence
or occurrence of any of the following:

          6.1.   Any neglect or breach of duty by Drobny, or  any
failure  by Drobny to perform, to the reasonable satisfaction  of
the CEO, such duties as may be delegated to Drobny by the Company
from time to time.

          6.2.   If Drobny is convicted of a felony or files  for
any  protection under the federal bankruptcy laws  (or  any  such
proceeding  is  filed against Drobny and is not dismissed  within
90 days of such filing).
          
          6.3.   If  Drobny commits theft, larceny, embezzlement,
fraud,  any  acts of dishonesty, illegality, moral  turpitude  or
gross  mismanagement, as determined in good  faith  by  the  CEO,
whose determination shall be final and binding.

          6.4.   If  Drobny breaches any obligation set forth  in
Paragraphs  8, 9, 10 or 11 or materially and repeatedly  breaches
any other provision of this Agreement.
          
          6.5.  If Drobny breaches any term of that certain Asset

extent  that Drobny is precluded from performing the  duties  set
forth in this Agreement for a period of three (3) months or  more
within  any  twelve (12) month period.  Disability shall  not  be
proper  grounds for termination in the event that such disability
arises  from injuries received by Drobny while traveling  in  the
scope of his employment.
          
          6.8.   If Drobny fails to adhere to any Company  policy
or any future policy of Company.

     7.    Representations   and   Warranties.    Drobny   hereby
represents and warrants that as of the date of execution of  this

     8.   Confidentiality.  Drobny hereby acknowledges  that  the
Company  has  made  (or  may make) available  to  Drobny  certain
customer lists, product design information, performance standards
and  other  confidential and/or proprietary  information  of  the
Company  or licensed to the Company, including without limitation
trade secrets, copyrighted materials and/or financial information
of the Company (or any of its Affiliates, as defined in Paragraph
10  below)  including  without limitation  financial  statements,
reports  and  data  (collectively, the "Confidential  Material").
Except as essential to Drobny's obligations under this Agreement,
neither  Drobny nor any agent, employee, officer, or  independent
contractor of or retained by Drobny shall make any disclosure  of
this  Agreement,  the  terms of this Agreement,  or  any  of  the
Confidential   Material.   Except  as   essential   to   Drobny's
obligations under this Agreement, neither Drobny nor  any  agent,
employee,  officer, or independent contractor of or  retained  by
Drobny  shall make any duplication or other copy of  any  of  the
Confidential  Material.   Immediately  upon  request   from   the
Company,  Drobny  shall  return to the Company  all  Confidential
Material.  Drobny shall notify each person to whom any disclosure
is  made  that  such disclosure is made in confidence,  that  the
Confidential Material shall be kept in confidence by such person,
and  that  such person shall be bound by the provisions  of  this
Paragraph.

     9.    Proprietary   Information.   For  purposes   of   this
Agreement,  "Proprietary Information" shall mean any information,
observation,  data, written material, record, document,  computer
program,  software, firmware, invention, discovery,  improvement,
development,   tool,   machine,  apparatus,  appliance,   design,
promotional  idea,  customer  list, practice,  process,  formula,
method,  technique, trade secret, product and/or research related
to  the  actual  or  anticipated research, marketing  strategies,
pricing  information,  business records,  development,  products,
organization, business or finances of the Company (or any of  its
Affiliates).   All right, title and interest of  every  kind  and
nature  whatsoever  in and to the Proprietary  Information  made,
discussed,  developed, secured, obtained  or  learned  by  Drobny
during   the  term  of  this  Agreement,  or  the  60-day  period
immediately following termination of this Agreement, shall be the
sole  and  exclusive property of the Company for any purposes  or
uses whatsoever, and shall be disclosed promptly by Drobny to the
Company.  The covenants set forth in the preceding sentence shall
apply  regardless of whether any Proprietary Information is made,
discovered, developed, secured, obtained or learned (a) solely or
jointly  with  others,  (b) during the usual  hours  of  work  or
otherwise,  (c)  at  the request and upon the suggestion  of  the
Company or otherwise, or (d) with the Company's materials, tools,
instruments  or  on  the Company's premises  or  otherwise.   All
Proprietary  Information developed, created,  invented,  devised,
conceived  or discovered by Drobny that are subject to  copyright
protection are explicitly considered by Drobny and the Company to
be  works  made for hire to the extent permitted by law.   Drobny
hereby  assigns to the Company all of Drobny's right,  title  and
interest  in  and to the Proprietary Information.  Drobny  hereby
forever fully releases and discharges the Company, any Affiliates
of  the  Company  and  their respective officers,  directors  and
employees, from and against any and all claims, demands, damages,
liabilities,  costs  and expenses of Drobny arising  out  of,  or
relating  to, any Proprietary Information.  Drobny shall  execute
any  documents and take any action the Company may deem necessary
or  appropriate  to effectuate the provisions of this  Agreement,
including  without limitation assisting the Company in  obtaining
and/or  maintaining patents, copyrights or similar rights to  any
Proprietary Information assigned to the Company, if the  Company,
in  its sole discretion, requests such assistance.  Drobny  shall
comply with any reasonable rules established from time to time by
the  Company  for  the protection of the confidentiality  of  any
Proprietary Information.  Drobny irrevocably appoints the CEO  to
act  as  Drobny's agent and attorney-in-fact to perform all  acts
necessary  to  obtain  and/or maintain  patents,  copyrights  and
similar rights to any Proprietary Information assigned by  Drobny
to  the  Company under this Agreement if (a)  Drobny  refuses  to
perform those acts, or (b) is unavailable, within the meaning  of
any  applicable laws.  Drobny acknowledges that the grant of  the
foregoing power of attorney is coupled with an interest and shall
survive the death or disability of Drobny.  Drobny shall promptly
disclose  to  the  Company,  in confidence  (a)  all  Proprietary
Information  that  Drobny  creates  during  the  term   of   this
Agreement, and (b) all patent applications filed by Drobny within
one  year  after termination of this Agreement.  Any  application
 for  a  patent, copyright registration or similar right filed  by
Drobny within one year after termination of this Agreement  shall
be  presumed  to  relate  to Proprietary Information  created  by
Drobny during the term of this Agreement, unless Drobny can prove
otherwise.   Nothing  contained  in  this  Agreement   shall   be
construed  to  preclude the Company from exercising  all  of  its
rights  and privileges as sole and exclusive owner of all of  the
Proprietary Information owned by or assigned to the Company under
this  Agreement.   The  Company, in exercising  such  rights  and
privileges  with  respect to any particular item  of  Proprietary
Information, may decide not to file any patent application or any
copyright  registration  on  such  Proprietary  Information,  may
decide  to  maintain such Proprietary Information as  secret  and
confidential,   or   may  decide  to  abandon  such   Proprietary
Information or dedicate it to the public.  Drobny shall  have  no
authority  to exercise any rights or privileges with  respect  to
the  Proprietary Information owned by or assigned to the  Company
under  this  Agreement.  This Agreement does  not  apply  to  any
Proprietary Information that qualifies fully under the provisions
of California Labor Code Section 2870 or any similar or successor
statute.

     10.  Competition. Drobny acknowledges that this Agreement is
being  entered in connection with the purchase by the Company  of
substantially all of the assets of a corporation with respect  to
which  Drobny and his spouse are the sole shareholders.   To  the
extent permitted by applicable law, during the period of time set
forth in Paragraph 10.5 below:
     
          10.1.  Drobny shall not, directly or indirectly, engage
or   invest  in,  own,  manage,  operate,  finance,  control,  or
participate in the ownership, management, operation,  or  control
of,  be  employed by, associated with, or in any manner connected
with,  or  render  services  or advice  to,  any  business  whose
products  or  activities compete in whole or  in  part  with  the
products or business of the Company within the world.
          
          10.2.  Drobny  shall not undertake  any  employment  or
activity  competitive  with  the  Company's  business,  including
without  limitation  the  inducement  or  solicitation   of   the
Company's customers, if the duties or work of, in connection with
or  related to such competitive employment or activity  would  or
might cause Drobny to reveal or use any Confidential Material  or
Proprietary  Information.   The restriction  set  forth  in  this
Paragraph  10.2 shall not be limited to a particular geographical
area.
          
          10.3.  Drobny shall not, directly or indirectly, either
for  himself or any other person, (A) induce or attempt to induce
any  employee of the Company or any Affiliate (as defined  below)
to  leave  the  employ of such company, (B) in any way  interfere
with  the  relationship between the Company or any Affiliate  and
any employee of such company, (C) employ, or otherwise engage  as
an  employee, independent contractor, or otherwise, any  employee
of  the  Company or any Affiliate, or (D) induce  or  attempt  to
induce any customer, supplier, licensee, or business relation  of
the  Company or any Affiliate to cease doing business  with  such
company,  or  in any way interfere with the relationship  between
any  customer, supplier, licensee, or business relation  of  such
company.
          
          10.4.  Drobny shall not, directly or indirectly, either
for  himself  or  any other person, solicit the business  of  any
person  known  to Drobny to be a customer of the Company  or  any
Affiliate, whether or not Drobny had business or personal contact
with such person, unless Drobny's solicitation of such person  is
done  in connection with a business that is not competitive  with
that of the Company or any Affiliate.
          
          10.5.  The duration of the covenants set forth in  this
Paragraph 10 shall be the entire term of Drobny's employment with
the  Company plus a period of two years after the termination  of
such  employment. Drobny agrees that this covenant is  reasonable
with  respect  to  its duration, geographical  area,  and  scope.
Notwithstanding   such  restriction,  Drobny  may   purchase   or
otherwise acquire up to (but not more than) three percent (3%) of
any  class of securities of any enterprise (but without otherwise
participating  in  the  activities of such  enterprise)  if  such
securities  are  listed  on any national or  regional  securities
exchange  or  have  been registered under Section  12(g)  of  the
Securities Exchange Act of 1934.
     
     In the event of a breach by Drobny of any covenant set forth
in  this Paragraph 10, the term of such covenant will be extended
by  the period of the duration of such breach, provided, however,
that  such extension shall be limited to two years.  In  addition
to  the  Company's right to damages and any other rights  it  may
have,  to obtain injunctive or other equitable relief to restrain
any  breach  or  threatened breach or otherwise  to  specifically
enforce  the  provisions of this Paragraph,  Drobny  agrees  that
money damages alone would be inadequate to compensate the Company
and would be an inadequate remedy for such breach.  If a court of
competent  jurisdiction  holds that  the  obligations  of  Drobny
pursuant  to  this  Paragraph 10 are  unenforceable  due  to  the
duration, geographical area or scope of this covenant, then  such
duration,  geographical area or scope of this covenant  shall  be
reduced  to  the least degree necessary to render  this  covenant
enforceable.   For purposes of this Agreement, "Affiliate"  shall
mean  any  partner, employee, director, shareholder,  officer  of
Company  or  any person or entity controlled by, controlling,  or
under common control with, directly or indirectly, the Company.
     
     Drobny  shall  be released from his obligations  under  this
Paragraph  10  upon  the occurrence of either  of  the  following
events:   (a)  the  material breach by  the  Company  under  this
Agreement   adjudicated  as  such  by  a   court   of   competent
jurisdiction,   or  (b)  Jon  Gilbert  and  Michael   Silverman's
termination of their involvement with the Company.
     
     11.   Business  Opportunities.   During  the  term  of  this
Agreement,  if  Drobny  (or  any  agent,  employee,  officer   or
independent  contractor of or retained by Drobny)  becomes  aware
of,   or  develops,  creates,  invests,  devises,  conceives   or
discovers,  any project, investment, venture, business  or  other
opportunity  (any  of  the preceding, an "Opportunity")  that  is
similar to, competitive with, related to or in the same field  as
the  Company  or  any  Affiliate,  or  any  project,  investment,
venture, or business of the Company or any Affiliate, then Drobny
shall  so  notify  the Company immediately  in  writing  of  such
Opportunity  and shall use Drobny's good-faith efforts  to  cause
the Company to have the opportunity to invest in, participate  in
or otherwise become affiliated with such Opportunity.

     12.    Survival.    The  representations,   warranties   and
covenants   of  Drobny  in  this  Agreement  shall  survive   any
termination of this Agreement.

     13.  Governing Law.  This Agreement shall be governed by and
construed in accordance with the laws of the State of California.

     14.  Further Assurances.  Each party to this Agreement shall
execute all instruments and documents and take all actions as may
be reasonably required to effectuate this Agreement.

counterparts, each of which shall be deemed an original  and  all
of which together shall constitute one document.

     17.    Time  of  Essence.   Time  and  strict  and  punctual
performance are of the essence with respect to each provision  of
this Agreement.

     18.    Attorney's  Fees.   In  the  event  any   litigation,
arbitration,  mediation,  or other proceeding  ("Proceeding")  is
initiated  by  any  party(ies) against any  other  party(ies)  to
enforce, interpret or otherwise obtain judicial or quasi-judicial
relief   in   connection  with  this  Agreement,  the  prevailing
party(ies)  in such Proceeding shall be entitled to recover  from
the  unsuccessful  party(ies)  all costs,  expenses,  and  actual
attorney's fees relating to or arising out of (d) such Proceeding
(whether  or  not  such  Proceeding proceeds  to  judgment),  and
(e)  any post-judgment or post-award proceeding including without
limitation  one  to enforce any judgment or award resulting  from
any such Proceeding.  Any such judgment or award shall contain  a
specific  provision  for the recovery of  all  such  subsequently
incurred costs, expenses, and actual attorney's fees.
