      schedule by mutual consent.  In any event the quantities of the VLUs

      quantities scheduled to be supplied within 4 months following the date

         of this termination of production.

         "Planned to be shipped" shall be interpreted in accordance with the
         last update of the monthly delivery rate.

         In such case all inventory becomes the property of Buyer, including
         all parts and partly completed units.  Seller shall ship same (at
         Buyer's expense) to a destination requested by Buyer.

     prevent the aggrieved party from applying to a court for provisional
     relief.  An application for provisional relief to a court shall not relieve
     either party of its obligation under this

    Section 14 and shall not alter the power of the mediator to determine the
    rights and obligations of the Parties under this Agreement.

16.1.1   Either party may initiate the dispute resolution process by sending a
         written notice (which the parties hereby agree will automatically toll
         any applicable statute of limitations) of the alleged dispute and the
         alleged wrong suffered, to the members of the Dispute Resolution
         Committee, consisting of the following individuals at Seller and Buyer
         or their successors, who shall be persons holding positions at a level
         substantially equivalent to those named ("Dispute Committee"):

              SELLER                        BUYER
              ------                        -----

         General Manager          The Chairman of the Board
         Telematics Division

16.1.2   Upon receipt of any such notice, the Dispute Committee, using all
         available and relevant resources of their respective companies, shall
         promptly investigate the facts and circumstances surrounding the
         disputes and shall meet (either in person or by telephone) to attempt
         to resolve the dispute.  Any resolution reached, either informally or
         in such a meeting, shall be committed to writing and signed by the
         Dis-

         pute Committee and communicated to the appropriate management of the
         parties for implementation.  This resolution shall be conclusive and
         binding upon the parties.

16.1.3   If a dispute is not resolved by the Dispute Committee, any party may
         pursue its action as set forth in Section 16.2 below.

16.1.4   Each of the parties specifically acknowledges and agrees that remedies
         at law for any breach of this Agreement would be inadequate, and that
         the parties, in addition to any other relief available, shall be
         entitled to specific performance of all of the provisions of this
         Agreement.


16.2     Within 5 days after the Dispute Committee has failed to resolve any
         dispute, the parties shall meet to discuss and agree upon the
         qualifications which they desire a mediator to possess.

         Any party may suggest one or more candidates to fill the position of
         mediator.

         The parties shall then attempt to select a mutually acceptable
         candidate.

16.2.1   Once a candidate has been agreed upon by the parties, the candidate
         shall be invited to serve as the mediator.  If the candidate declines
         to do so, the parties 



                                          21

           [****Omitted and Filed Separately With the Commission Pursuant
                     to a Request for Confidential Treatment.]


         shall meet or confer again to select another qualified candidate. 
         This process shall be repeated until a mediator is selected and agrees
         to serve.  If, however, after 30 days, the parties are unable to agree
         upon a mediator, the mediator shall be selected by the President of
         the New York Arbitration Association, whose selection shall be binding
         upon the parties.

16.2.2   During the selection and mediation processes, each party shall
         disclose to the other party any circumstances known to it which would
         create any reasonable doubt about the impartiality or neutrality of an
         individual who is being considered as a potential mediator or who is
         serving as the mediator.  The candidate or mediator may be asked to
         explain such circumstances and be required to disclose any information
         which would constitute grounds for doubt as to the candidate's or the
         mediator's impartiality or neutrality.  If any such circumstances have
         been disclosed, either before or after the individual's appointment as
         mediator, the candidate or mediator shall not serve or continue to
         serve unless both parties agree.

16.2.3   The mediator's compensation rate shall be determined and agreed upon
         at or prior to the mediator's appointment.  The mediator's
         compensation and all other inci-

                     to a Request for Confidential Treatment.]


         dental costs incurred during the mediation process will be shared
         equally by the parties.

16.2.4   The mediator shall be neutral and impartial and shall use the laws of
         the State of New York to resolve the dispute between the parties.

16.2.5   The mediator shall control the procedural aspects of the mediation. 
         The parties shall cooperate fully with the mediator at all times.

16.2.6   The mediator is free to meet and communicate separately with each
         party.

16.2.7   The mediator shall, in consultation with the parties, fix the agenda
         for all meetings.

16.2.8   Each party may be represented by counsel, who shall be authorized to
         recommend settlement options to their principals.

16.2.9   The mediation process shall be conducted expeditiously and shall be
         completed in less than 120 days from the date the mediator was
         selected.  Each representative shall make every effort to be available
         for meetings, and the mediator shall ensure that he is able to devote
         all the time necessary to quickly and effectively mediate the dispute.

16.2.10  The entire mediation process shall remain confidential.  The parties
         or the mediator shall not disclose

           [****Omitted and Filed Separately With the Commission Pursuant
                     to a Request for Confidential Treatment.]


         information regarding the process, including settlement terms, unless
         the parties agree otherwise.  The mediator may obtain assistance and
         independent expert advice with the agreement of and at the expense of
         the parties.

16.2.11  The mediator shall not be liable for any good faith act or omission in
         connection with his role as mediator.

16.2.12  The mediation shall take place in New York City.

16.2.13  The mediator's decision shall be final and binding upon both parties.


17. NEW YORK LAW

    This Agreement shall be governed by and construed in accordance with the
    laws of the State of New York as the same or any succeeding provision of
    law may be in effect from time to time.  For the purposes of any dispute
    between the parties, this Agreement shall be construed as if all parties
    were resident and doing business in New York.  If there are any ambiguities

18. MISCELLANEOUS PROVISIONS

18.1 RELATIONSHIP OF PARTIES.  This Agreement does not constitute and shall not
     be construed as constituting a partnership or joint venture between The
     Parties.  Neither party shall represent that it is an agent for the other
     party.  Both parties acknowledge that the relationship of Seller and Buyer
     shall be and at all times remain one of an independent contractor, and so
     shall represent themselves to third parties.  Neither party has the right
     to bind the other in any manner.

18.2 SUCCESSORS.  This Agreement shall be binding upon and inure to the benefit
     of the parties and their respective executors, heirs, legal
     representatives, successors and assigns.


18.3 ASSIGNMENT.  Parties shall not assign, transfer or sell any of their rights
     hereunder to any third party without the prior written permission of the
     other Party, which permission shall not be unreasonably withheld; provided,
     however, that Teletrac may assign this agreement, without the permission
     from Tadiran, as part of sale or transfer of all or substantially all of
     its assets and business.  Notwithstanding the above Tadiran may assign this
     agreement to its subsidiary created as part of a corporate reorganization,
     provided Tadiran shall guarantee the performance of such 



                                          25
<PAGE>

           [****Omitted and Filed Separately With the Commission Pursuant
                     to a Request for Confidential Treatment.]


    subsidiary.  No rights hereunder shall devolve by operation of law or
    otherwise upon any assignee, receiver, liquidator, trustee or other party. 
    The VLUs delivered hereunder shall be manufactured only by Tadiran Ltd.,
    its legitimate assigns or Tadiran LTD's subcontractors.


18.4 NO WAIVER.  Failure of either party to insist upon strict performance of
     any of the terms, conditions, provisions or Specifications within this
     Agreement (including the exhibits), or the delay in exercising any of its
     remedies, shall not constitute a waiver of such terms conditions,
     provisions or Specifications or a waiver of any default thereof nor the
     remedy of such default.


18.5 SURVIVAL OF OBLIGATIONS.  Each party's obligations under this Agreement
     which, by their nature, would continue beyond termination or expiration of
     this Agreement, including by way of illustration only and not limitation,
     Section 4 or any Section related to confidentiality, warranty and
     indemnification, shall survive termination or expiration of this Agreement
     by either party for any reason.


18.6 ENTIRE AGREEMENT.  This Agreement, together with all exhibits hereto,
     constitute the entire agreement and understanding between the parties as to
     the subject matter of this Agreement, and supersedes all previous
     communications,

                     to a Request for Confidential Treatment.]


    representations or agreements.  Any other document issued by Buyer shall be
    deemed to be issued only for administrative convenience and no term or
    condition thereof, including any purchase order, shall supersede the terms
    and conditions of this Agreement.


18.7 REMEDIES.  Except as specifically set forth in this Agreement, all remedies
     available to either party for breach of this Agreement are cumulative, and
     may be exercised concurrently or separately, and the exercise of any one
     remedy shall not be deemed an election of such remedy to the exclusion of
     other remedies.


18.8 HEADINGS.  The paragraph headings used in this Agreement are for
     convenience of reference only, and shall not in any way limit or amplify
     the terms and provisions hereof, nor enter into the interpretation of this
     Agreement.


18.9 BINDING AGREEMENT.  The persons executing this Agreement on behalf of the
     parties have been duly and validly authorized to do so, and this Agreement
     is a valid and binding obligation of the parties.

      which shall be deemed an original and all of which shall constitute
      one and the same Agreement.

18.11 SEVERABILITY.  If any term of this Agreement shall be unlawful, void
      or unenforceable, such term shall be deemed omitted to the extent
      prohibited or invalid, but the remainder of this Agreement shall not
      be invalidated and shall be given effect as far as possible.  If any
      term hereof is found by a court or arbitrator to be over-broad, such
      term shall be limited to the extent required to make it enforceable.

      otherwise changed except by a written instrument executed by both
      parties.


18.13 ATTORNEY'S FEES.  If any action or proceeding (judicial or
      non-judicial) is brought to interpret any term or provisions of this
      Agreement, the prevailing party shall be entitled to costs and
      reasonable attorney's fees in addition to any other relief to which it

                                      Amendment
                             to VLU Production Agreement
 
         This Amendment to VLU Production Agreement dated September 6, 1996
("Amendment") is made as of May 28, 1997 by and between Tadiran Ltd. ("Seller"
or "Tadiran") and Teletrac Inc. ("Buyer" or "Teletrac").

         Whereas, due to interference with proper function of the VLU caused by
unrelated third parties (the "Interference"), Specifications of the VLU Exhibit
"A" to the Agreement have to be modified; and

         Whereas, in order to resolve the above problem, Teletrac requested
Tadiran, in accordance with the Agreement, to change the Specifications of the
VLU and develop a modified VLU (the "Modified VLU"); and

         Whereas, the Parties wish to cooperate in order to resolve the above
problem.

         The Parties hereby agree as follows:

         1.   Terms used in this Agreement shall have the same meaning as
              defined in the Agreement.

         2.   Based on data and information provided by Teletrac and
              independently confirmed by Tadiran, Tadiran shall make all
              reasonable efforts to develop a Modified VLU which shall provide
              technical solution to the Interference.  Joint teams of Tadiran
              and Teletrac (the "Joint Team") shall cooperate in definition of
              the changes.  Upon development of the Modified VLU the Joint Team
              shall perform laboratory and field tests in order to determine
              the suitability of the technical solution.  Should the solution
              be found acceptable, it shall be approved by the Joint Team.

         3.   The Parties hereby acknowledge that the above development shall
              require joint efforts of both Parties.  If the proposed technical
              solutions are not successful, despite their efforts, the Parties 

                                           
<PAGE>

           [****Omitted and Filed Separately With the Commission Pursuant
                     to a Request for Confidential Treatment.]


              shall coordinate further steps in order to resolve the problem of
              Interferences.

         4.   Upon approval of the Joint Team, the Specifications shall be
              changed in writing in accordance with the approved technical
              solution (the "Revised Specifications"), which shall be signed by
              both Parties.  The Parties hereby undertake to make reasonable
              efforts to approve the Revised Specifications and to instruct
              their members of the Joint Team to promote the approval of the
              technical solution in the speediest and most efficient manner.

         5.   Upon approval of Revised Specifications, Tadiran shall submit to
              Teletrac a proposal for retrofit costs (excluding R&D) and for
              adjustment of the price for all new VLU Units to be ordered under
              the Agreement.

              5.1. It is hereby agreed that the retrofit costs shall not exceed
                   US $**** per Unit if **** has to be replaced and US $****
                   per Unit, if **** have to be replaced.  The Parties shall
                   add the retrofit costs to the VLU price defined in the
                   Agreement for all retrofit Units.

              5.2. It is hereby agreed that the price for all new VLU Units to
                   be ordered under the Agreement shall be adjusted but shall
                   not exceed US $**** per Unit, if **** has to be replaced or
                   US $**** per Unit, if **** have to be replaced.

              5.3. The above "not to exceed" estimates are based on assumption
                   that the cost of **** to Tadiran shall not exceed US $****. 
                   If the cost of **** exceeds US $****, the difference shall
                   be added to the above "not to exceed" estimates.

              5.4. As soon as production facilities could be readjusted and the
                   prices be agreed upon (the "Modification Effective Date"),
                   all Units ordered under the Agreement shall be Modified VLUs
                   and manufactured in accordance with the Revised
                   Specifications.

         6.   In order to preserve the production capacity established under
              the Agreement and within the framework of mutual cooperation, the
              Parties hereby agree to the following changes in the on-going
              production of the VLUs:

              6.1. from the date of execution of this Amendment until
                   Modification Effective Date, the VLU's shall be manufactured
                   without components which require modification and without
                   final acceptance tests.  These VLUs shall be delivered to
                   bonded warehouse in Thailand and upon such delivery the
                   title to these VLUs shall pass to Teletrac ("Warehouse
                   VLUs").  Tadiran represents and Teletrac shall have the
                   right to verify that the storing conditions in the bonded
                   warehouse are adequate.  Teletrac shall have the right to
                   inspect the bonded warehouse from time to time.

                   The cost of storage and insurance premium for the duration
                   of the storage in the bonded warehouse (up to four months)
                   shall be paid by Tadiran.  If by the end of the four-month
                   period the Revised Specifications have not been approved,
                   Tadiran shall complete the manufacture of the Warehouse VLUs
                   and shall ship them to Teletrac, unless the Parties agree to
                   continue their joint development effort.

              6.2. Starting with the Modification Effective Date, all Warehouse
                   VLUs shall be modified according to Revised Specifications
                   and delivered to Teletrac in accordance with the Agreement
                   at a minimum monthly rate of **** Units a month (in addition
                   to regular deliveries as per section 6.3 below).  Warranty
                   for Warehouse VLUs shall begin upon actual delivery to
                   Teletrac in accordance with the Agreement.

              6.3. For the duration of the development of the Modified VLUs
                   until Modification Effective Date, the monthly delivery rate
                   defined in the Agreement may be decreased to **** VLUs.  For
                   the purpose of determination of the monthly delivery rate,
                   delivery to the bonded

                     to a Request for Confidential Treatment.]


                   warehouse shall be considered a "delivery."  On Modification
                   Effective Date the monthly delivery rate of regular
                   deliveries shall be raised to a minimum of **** Units a
                   month.

              6.4. Notwithstanding the above, it is hereby agreed that payments
                   for Warehouse VLUs shall be made in the following manner: 
                   ****% of the payment due for each delivery shall be paid
                   upon delivery to the bonded warehouse and the other ****%
                   plus retrofit costs shall be paid upon shipment of the
                   Modified VLUs in accordance with the Agreement.  For
                   avoidance of doubt these terms of payment shall apply to
                   Warehouse VLUs only and terms of payment for any other VLUs
                   shall be in accordance with the Agreement.

                   The Letter of Credit issued under the Agreement in favor of
                   Tadiran shall apply to all payments under the Agreement and
                   under this Amendment.

         7.   All other provisions of the Agreement unless amended specifically
              herein shall remain intact and Teletrac shall remain importer of
              record of all VLUs and Modified VLUs.

                                 MOBILE DATA TERMINAL
                                  PURCHASE AGREEMENT


    This Mobile Data Terminal Purchase Agreement (this "Agreement") by and
between Teletrac Inc., 7391 Lincoln Way, Garden Grove, California 92641
("Teletrac") and Micronet Ltd., 7 Hashalom Road, Tel-Aviv, Israel 67892
("Micronet"), is made effective as of the 8th day of February, 1996.  The
parties hereby agree as follows:

1.  AGREEMENT TO PURCHASE AND SELL.

1.1 SALE OF PRODUCTS.  Teletrac shall purchase from Micronet a minimum of ****
Terminals, and Micronet shall sell to Teletrac a minimum of **** Terminals, on
the terms set forth herein and on the attached purchase order #****.  Terminals
are defined as Micronet's production level Net-950 Mobile Data terminals.  The
description and technical, engineering, and operational specifications for the
Terminals and the protocol (the "Specifications") are set forth in Appendix "A",
all of the terms of which are incorporated herein by this reference.  Micronet
shall imprint serial numbers (including bar coded serial numbers) on the back
panel of each Terminal, and shall print, in white, "Net-950" on each Terminal.

1.2 INITIAL ORDER.  Teletrac hereby places a firm and irrevocable order for
**** Terminals from Micronet (the "Initial Order"), all of which will be
purchased in accordance with the terms and conditions of this agreement.

1.3 SUBSEQUENT ORDERS.  After the Initial Order for **** Terminals ordered
hereunder have been purchased, orders for additional Terminals shall be in
writing and shall specify arrival dates of not less than 10 weeks from delivery
of the order to Micronet.  Micronet may, by written notification delivered to
Teletrac within 10 working days of Micronet Receipt of a subsequent order, elect
not to fill the subsequent order.  If Micronet does not notify Teletrac of its
election to not fill the subsequent order, the order shall be filled as
described in this paragraph 1.3 and in accordance with the other terms of this
Agreement.  All subsequent orders shall be for at least **** Terminals per
order.  The prices set forth in paragraph 3.1 shall apply to subsequent orders,
but shall be subject to an annual increase on each anniversary of the effective
date of this Agreement, in an amount 


                                           
<PAGE>

           [****Omitted and Filed Separately With the Commission Pursuant
                     to a Request for Confidential Treatment.]



equal to the increase in the U.S. Consumer Price Index ("CPI") over the prior
12-month period.  Micronet shall use its reasonable efforts to expeditiously
fill subsequent orders.

1.4 PURCHASE ORDERS.  Purchase orders will be issued by Teletrac for purposes
of administration of delivery and quantity schedules.  No term or condition of
any purchase order shall supersede the terms and conditions of this agreement. 
In the event of any conflict between the terms of any purchase order and this
Agreement, the terms of this Agreement shall control.  Micronet shall promptly
honor and fulfill all purchase orders in accordance with the terms and
conditions of this Agreement.

2.  QUALITY CONTROL.

2.1 DEVELOPMENT.  Micronet acknowledges and agrees that Teletrac is not a
participant in the development of the Terminals and is not liable for the
design, any design defects, product liability, strict liability (i.e, liability
without fault), or failure of the Terminals to meet the Specifications.

2.2 TEST UNITS.  Teletrac acknowledges that it has been supplied **** test
units and that it has tested these units and found them acceptable and
conforming to the specifications and that the plastics and graphics are also
acceptable.  Teletrac confirms that Micronet may proceed with production units
based on these test units.  The test units shall be included in the count of
Spare terminals as defined in Paragraph 5.2.

2.3 ACCEPTANCE/REJECTION OF TERMINALS.  Within two weeks of receipt, Teletrac
shall inspect all incoming Terminals (each shipment of Terminals shall be
referred to as a "Lot") to insure compliance with the Specifications.  Teletrac
may reject the total lot received (if more than ****% of the Lot does not comply
with Specifications), or portions of the Lot, as to those Terminals that do not
comply with Specifications.  Teletrac shall inspect Terminals on a sampling
basis.  Rejected Terminals shall be promptly returned to Micronet; provided,
however, that rejected Terminals shall be Held so that they can be shipped in
bulk, and will be shipped to Micronet not more frequently than once per month. 
Micronet shall bear all costs of freight, duty, insurance and other costs
incurred in returning the Terminals to Micronet and shipping new Terminals to
replace the rejected Terminals to Teletrac.  Micronet acknowledges and agrees
that timely receipt of conforming Terminals is critical to Teletrac and that
Teletrac shall suffer severe damages if substantial numbers of Terminals are
non-conforming.  The parties recognize that the full impact of such breach would
be very difficult to assess and it would be difficult to fix the actual amount
of damages.  Therefore, to avoid possible disputes, the parties agree that if
more than 



                                          2
<PAGE>

           [****Omitted and Filed Separately With the Commission Pursuant
                     to a Request for Confidential Treatment.]



****% of a Lot is rejected and returned, Micronet shall pay to Teletrac
liquidated damages of US $**** per rejected Terminal per day beginning after the
tenth day following Micronet's receipt of each non-conforming Terminal unit
replaced.  This amount shall be invoiced and paid by Micronet within 30 calendar
days of receipt of invoice.  If not paid by Micronet, the amount shall be
applied against monies owed for Terminals.  The amount established under this
paragraph for liquidated damages represents a reasonable attempt by the parties
to state an amount that bears a reasonable relationship to actual damages and
does not constitute a penalty.  Notwithstanding anything in this paragraph to
the contrary, Teletrac shall specify the reasons for the rejection and give
Micronet an opportunity to discuss the rejection prior to imposition of the
liquidated damages described in this paragraph.

3.  PAYMENT.

3.1 PRICE.  The purchase price for each Terminal (including bracket and screws)
shall be U.S. $**** per unit (the "Purchase Price").  The Purchase Price
includes packaging, export duties, Israeli taxes, and handling costs.  Except as
otherwise provided herein, Teletrac is responsible for insurance and shipping
costs and shall select the carrier.  Teletrac is also responsible for import
duties and U.S. taxes, provided that Micronet includes with each shipment a
"Country of Origin Certificate (Form A)".

3.2 INVOICING.  Invoices for Terminals shall contain, at a minimum, the
Purchase Price in U.S. dollars, purchase order number, invoice date, quantity,
description, invoice number, reference to this Agreement, ship to name and
address, remit to name and address and method and name of carrier.

3.3 TERMS OF PAYMENT.

    DOWN PAYMENT.  Teletrac, by Bank wire transfer, shall make a down payment
to Micronet's account in the amount of U.S. $**** within 4 business days of the
effective date of this Agreement.  Micronet shall Invoice Teletrac for this
amount.  The down payment shall be applied towards the last shipment payment.

Payments for all other shipments, as per paragraph 4 below, will be made by wire
transfer immediately prior to each delivery.

4.  SHIPMENT.

4.1 SHIPMENT TERMS.  Unless Teletrac notifies Micronet otherwise, as provided
in Paragraph 12.2, Teletrac hereby orders **** Terminals to be shipped to
Teletrac's facility described in paragraph 4.3, on the dates set forth in the
following Shipment Schedule:

<PAGE>

           [****Omitted and Filed Separately With the Commission Pursuant
                     to a Request for Confidential Treatment.]


- ------------  -------------  ------------------------------------------------
Number of      Terminal             Date shipped to Teletrac Facility
Terminals      Type 
- ------------  -------------  ------------------------------------------------
   ****       Net-950        Within 35 calendar days after effective date.
   ****       Net-950        Within 14 calendar days thereafter
   ****       Net-950        Within 60 Calendar days thereafter
- ------------  -------------  ------------------------------------------------
NOTE:

Micronet is allowed to accelerate shipments without limitation on quantities and
Teletrac is owed to payment terms as specified in Paragraph 3.3 above.

Shipment dates are conditional on Teletrac complying on time with payment terms
of paragraph 3.3 above.

4.2 LATE DELIVERIES.  Micronet acknowledges and agrees that time is of the
essence in shipment of the Terminals and Teletrac shall suffer severe damages if
conforming Terminals are not shipped in accordance with the Shipment schedule. 
The parties recognize that the full impact of such a breach would be very
difficult to assess and it would be difficult to fix the actual amount of
damages.  Therefore to avoid possible disputes the parties agree that if the
shipment schedule slips by more than 15 working days due to Micronet's failure
to ship conforming Terminals, a late charge of U.S. $**** per terminal per
working day shall be imposed until the breach is cured; provided, however,that
the late charges for orders shipped under the Initial Order shall not exceed
$****.

The late charge will be invoiced by Teletrac and paid by Micronet within 30
calendar days of date of invoice.  If not paid by Micronet, the amount shall be
applied against monies owed for terminals.

The amount established under this paragraph for liquidated damages represents a
reasonable attempt by the parties to state an amount that bears a reasonable
relationship to actual damages and does not constitute a penalty.


4.3 RESCHEDULING SHIPMENT DATES

    Teletrac allows Micronet to accelerate shipment dates and to deliver
    Teletrac bigger quantities than those stipulated in Paragraph 4.1 above.

           [****Omitted and Filed Separately With the Commission Pursuant
                     to a Request for Confidential Treatment.]


4.4 FOB POINT.  All Terminals are F.O.B Ben-Gurion Airport, Israel, unless
Teletrac notifies Micronet that Terminals are to be sent by ship rather than
air.  Shipment address is Teletrac location at 7391 Lincoln Way, Garden Grove,
California 92641.

4.5 TITLE, RISK OF LOSS, INSURANCE.  Title to the Terminals and risk of loss or
damage shall pass from Micronet to Teletrac upon Micronet's delivery to the
carrier at the F.O.B. point.

4.6 METHOD OF SHIPMENT. Micronet shall at its sole expense, provide for all
crating, packaging and packing in shipping containers that are designed to
provide adequate protection for the Terminals during shipping.  Each Terminal is
to be bundled with its necessary bracket and screws and washers, appropriately
protected.  Terminals shall be packaged in bulk in quantities of up to 50.

5.  WARRANTY AND SERVICE TERMS.

5.1 WARRANTY TERMS.  Micronet hereby warrants the Terminals to be in full
compliance with the Specifications and to be free from defects in workmanship
and materials (the "Warranty") for the shorter of two years from the date of
arrival at Teletrac's facility or one year after the Terminals have been
delivered by Teletrac to a third party customer ("the warranty period"). 
Teletrac will provide Micronet with monthly reports containing the serial
numbers of all terminals delivered to customers during the preceding month.

Micronet also warrants the merchantability and fitness for use of the 
terminals. Terminals that are repaired or replaced during the Warranty Period 
shall be warranted for the longer of the period of time remaining under the 
original warranty period or 90 working days.  Micronet hereby (a) consents to 
Teletrac's right at Teletrac's option to assign the warranty, or the 
remaining portion thereof, to Teletrac's customers, and (b) agrees to perform 
the obligations described in this paragraph 5 for the benefit of such 
customers.  During the Warranty Period Micronet shall bear all out of pocket 
costs to repair or replace defective Terminals, including, without 
limitation, all costs of returning the Terminals to Micronet and shipping 
repaired or replaced Terminals to Teletrac.

5.2 PROCEDURES.  Micronet shall, at its cost, manufacture and ship to Teletrac,
with the first shipment, **** additional terminals.  These along with the ****
approved test units will serve as "Spare Terminals".  Teletrac shall as
necessary, replace defective Terminals with Spare Terminals, or replace parts
from the Spare Terminals, accumulating the defective Terminals until the earlier
of (a) 10 defective Terminals are being held, or (b) 



                                          5
<PAGE>

           [****Omitted and Filed Separately With the Commission Pursuant
                     to a Request for Confidential Treatment.]


3 months have passed since Teletrac's last shipment of defective Terminals to
Micronet.  Teletrac will then notify Micronet by FAX of the number of defective
Terminals it will ship to Micronet.  Within 3 working days of receipt of
Teletrac's FAX stating the number of defective Terminals being shipped, Micronet
shall (a) provide Teletrac a Return Material Authorization ("RMA") number by FAX
and (b) ship to Teletrac's California facility an equal number of replacement
Terminals to be used as Spare Terminals.  Spare Terminals will not be used for
any purpose other than as replacement for defective Terminals.  The procedures
described in this paragraph shall apply to service during the Warranty and
thereafter, except that post-warranty repairs will be subject to the charges
described in paragraphs 5.5 and 5.6 below.  RMA numbers must be used in all
correspondence with Micronet and must be clearly marked on all packages and
boxes shipped to Micronet.  Defective Terminals shall be sent to:


                        MICRONET LTD

                        7 HASHALOM ROAD
                        TEL-AVIV, ISRAEL 67892

Or if after May 1st 1996 to:

                        MICRONET LTD
                        IRIS BUILDING, 27 HAMETZUDA ST
                        AZUR, ISRAEL 58001

5.3 TIME OF REPAIR OR REPLACE.  If the number of defective Terminals exceeds
the number of Spare Terminals held by Teletrac, the additional defective
Terminals shall be repaired or replaced by Micronet within 14 working days, plus
transit time from Micronet to Teletrac, from the date the defective Terminals
are delivered to Micronet.  Micronet acknowledges and agrees that time is of the
essence in Teletrac's receipt of repaired or replaced Terminals.

5.4 FAILURES.  The failure rate will be considered too high if it exceeds any 
of the following: (a) ****% of the units in a single shipment fail the 
acceptance tests; (b) ****% (cumulative) delivered within a 12 month period 
fail the acceptance tests; or (c) ****% of the units delivered to customers 
and in warranty do not function in full compliance with the specifications. 
Malfunctions falling under the limitations in section 5.8 shall not be 
counted as failures.  If the failure rate is too high Micronet shall use its 
best efforts to make required engineering or production changes as promptly 
as possible to prevent the continued occurrence of such failures.  Teletrac 
may require a total recall of Terminals if such step is appropriate.  
Micronet shall 


                                          6
<PAGE>

           [****Omitted and Filed Separately With the Commission Pursuant
                     to a Request for Confidential Treatment.]


not be liable for consequential damages or lost profits or loss of business
opportunity by a third party customer.

5.5 POST-WARRANTY REPAIR.  For 12 months following the termination of the
Warranty Period, Terminals shall be repaired for U.S. $**** per hour.  Parts
shall be billed at Micronet's then prevailing rates.  After this 12 month
period, parts and labor shall be charged at Micronet's then prevailing rates,
not to exceed the annual increase in the U.S CPI over the prior 12-month period.
Repaired Terminals shall be in full compliance with the Specifications and will
be free from defects in material and workmanship for 90 working days from the
date the repaired Terminals or Replacement Terminals have been delivered to
Teletrac or to Teletrac's customer.

5.6 FREIGHT AND OTHER COSTS AFTER WARRANTY PERIOD.  After the Warranty period,
Teletrac shall bear all costs of shipping defective Terminals to Micronet and
cost of returning the repaired or replaced Terminals to Teletrac or Teletrac's
customer.  Teletrac is responsible, on its own or through a qualified
independent contractor, for installation, deinstallation, and reinstallation of
all Terminals after the Warranty Period.

5.7 CONTINUING AVAILABILITY AND CORRECTIONS.  Micronet shall, for a period of
five years from the effective date of this Agreement, maintain a repair facility
in Tel-Aviv or another location that is no more costly to ship to and will
require no longer transit periods than the Tel-Aviv facility and shall for the
same period, maintain service and repair capability, including spare parts
availability.  Upon the termination of the Warranty Period, Micronet shall, at
its cost, perform the following services for a period of two years and six
months from the effective date of this Agreement: (a) correct any original
design or manufacturing defects that were not detected prior to shipment of the
production Terminals if such defects can be corrected on a reasonable basis; and
(b) correct any firmware defects within 30 days of notification of such defects.
Micronet shall, for a period of 5 years from the effective date of this
agreement, correct other defects in the Terminals (including the firmware) and
work with Teletrac on modifications and enhancements to the design and
performance of the Terminals (including the firmware) at the presently existing
hourly rate for Micronet's personnel, plus an annual percentage increase equal
to the increase in the U.S. CPI over the prior 12-month period.  The terms of
this Paragraph 5 shall survive the termination of this agreement.

5.8 LIMITATIONS ON WARRANTY.  This warranty shall not apply to Terminals which
have been subject to accident, improper storage, mishandling, unauthorized
alteration, misuse, vandalism, neglect or which have not been properly installed
or maintained.

interest in or right to use the Teletrac Marks.

7.  NO CONSEQUENTIAL DAMAGES.

Without affecting Micronet's right to claim ordinary damages for Teletrac's
breach hereunder, in no event shall Teletrac be liable for incidental,
consequential or special damages, including, without limitation, frustration of
economic or business expectations, loss of profits, or loss of sales, arising
under or related to this Agreement or by reason of Teletrac's purchase or
failure to purchase Terminals hereunder.

User may not copy, reverse engineer, translate, port, modify or make 
derivative works of the Products.  User may not rent, disclose, publish, 
sell, assign, lease, sublicense, market, or transfer the Products or use them 
in any manner not expressly authorized by this Agreement.  User shall not 
derive or attempt to derive the source code or structure of all or any 
portion of the Products by reverse engineering, disassembly, decompilation or 
any other means.  User shall not use the Products to operate a service bureau 
or for any other use involving the processing of data of other persons or 
entities.  User may not use the data Products with any software other than 
the software Products provided to User under this license agreement.

User does not receive any, and Licensor retains all, ownership rights in the 
Products.  The Products are copyrighted and may not be copied, even if 
modified or merged with other Products.  User shall not alter or remove any 
copyright notice or proprietary legend contained in or on the Products.

Licensor's supplier shall be a third party beneficiary of Licensor's rights 
under this Agreement, but is not a party hereto and shall have no obligation 
hereunder.

2.  LIMITED WARRANTY AND LIABILITY.  Licensor warrants that the Products in 
the version and level that is current on the date of initial shipment to User 
will, for ninety (90) days from that date, substantially conform to 
Licensor's specifications, when used in a computer environment approved by 
Licensor.  The Products are complex and may contain some non-conformities, 
defects or errors. Licensor does not warrant that the Products will meet User 
needs or expectations, that operations of the Products will be error-free or 
uninterrupted, or that all nonconformities can or will be corrected.

User must notify Licensor within the 90-day warranty period of any warranty
claim.  Licensor's SOLE OBLIGATION and User's SOLE REMEDY under this Limited
Warranty is for Licensor, at Licensor's option, to

Products substantially conform to the specifications contained in Licensor's 
documentation, or, in Licensor's sole discretion, to refund the amount of the 
initial license fee previously paid by User for the non-conforming Product 
unit(s).

This Limited Warranty is void if any non-conformity has resulted from accident,
abuse, misuse, misapplication, or modification by someone other than Licensor. 
This Limited Warranty is non-transferable.

THE EXPRESS WARRANTY IN THIS SECTION 2 IS A LIMITED WARRANTY AND IT IS THE ONLY
WARRANTY MADE BY LICENSOR.  LICENSOR MAKES AND USER RECEIVES NO OTHER WARRANTY,
WHETHER EXPRESS OR IMPLIED, AND ALL WARRANTIES OF MERCHANTABILITY AND FITNESS
FOR ANY PARTICULAR PURPOSE ARE EXPRESSLY EXCLUDED.  THE STATED EXPRESS WARRANTY
IS THE EXCLUSIVE REMEDY FOR DAMAGES AND IS IN LIEU OF ALL LIABILITIES OR
OBLIGATIONS OF LICENSOR.

IN NO EVENT SHALL LICENSOR BE LIABLE FOR ANY DAMAGES, CLAIM OR LOSS INCURRED BY
USER (INCLUDING WITHOUT LIMITATION COMPENSATORY, INCIDENTAL, DIRECT, INDIRECT,
SPECIAL, CONSEQUENTIAL OR EXEMPLARY DAMAGES, LOST PROFITS, LOST SALES OR
BUSINESS, EXPENDITURES, INVESTMENTS, OR COMMITMENTS IN CONNECTION WITH ANY

NEGLIGENCE, STRICT LIABILITY, MISREPRESENTATION, AND OTHER TORTS.  IF LICENSOR'S

FOR ANY REASON WHATSOEVER BE HELD UNENFORCEABLE OR INAPPLICABLE, USER AGREES
THAT LICENSOR'S LIABILITY SHALL NOT EXCEED FIFTY PERCENT (50%) OF THE LICENSE
FEES PAID BY USER TO ETAK WITH RESPECT TO THE PRODUCT UNIT(S) AT ISSUE.  Some
states do not allow the exclusion or limitation of incidental or consequential
damages or the limitation of duration of an implied warranty, so the limitation
or exclusion herein may not apply to User.  This warranty shall not be
applicable to the extent that any provision of this warranty Is prohibited by
any federal, state or local law which cannot be preempted.  This warranty gives
User specific legal rights, and User may also have other rights which vary from
state to state.

                            Account Number ______________


This Agreement is effective _______________, 19___ among Data Securities 
International, Inc. ("DSI"), Etak, Inc. ("Depositor") and Teletrac, Inc. 
("Preferred Beneficiary"), who collectively may be referred to in this 
Agreement as "the parties."

A.  Depositor and Preferred Beneficiary have entered or will enter into a 
license agreement, development agreement, and/or other agreement regarding 
certain proprietary technology of Depositor (referred to in this Agreement as 
"the license agreement").

B.  Depositor desires to avoid disclosure of its proprietary technology 
except under certain limited circumstances.

C.  The availability of the proprietary technology of Depositor is critical 
to Preferred Beneficiary in the conduct of its business and, therefore, 
Preferred Beneficiary needs access to the proprietary technology under 
certain limited circumstances.

D.  Depositor and Preferred Beneficiary desire to establish an escrow with 
DSI to provide for the retention, administration and controlled access of the 
proprietary technology materials of Depositor.

E.  The parties desire this Agreement to be supplementary to the license 
agreement pursuant to 11 United States [Bankruptcy] Code, Section 365(n).

ARTICLE 1 -- DEPOSITS

1.1 OBLIGATION TO MAKE DEPOSIT.  Upon the signing of this Agreement by the 
parties, Depositor shall deliver to DSI the proprietary information and other 
materials ("deposit materials") required to be deposited by the license 
agreement or, if the license agreement does not identify the materials to be 
deposited with DSI, then such materials will be identified on an Attachment 
A. If Attachment A is applicable, it is to be prepared and signed by 
Depositor and Preferred Beneficiary.  DSI shall have no obligation with 
respect to the preparation, signing or delivery of Attachment A.

1.2 IDENTIFICATION OF TANGIBLE MEDIA.  Prior to the delivery of the deposit
materials to DSI, Depositor shall conspicuously label for 


                                          D(1)
<PAGE>

           [****Omitted and Filed Separately With the Commission Pursuant
                     to a Request for Confidential Treatment.]



                                      Etak, Inc.
                            Value Added Reseller Agreement

identification each document, magnetic tape, disk, or other tangible media 
upon which the deposit materials are written or stored.  Additionally, 
Depositor shall complete Attachment B to this Agreement by listing each such 
tangible media by the item label description, the type of media and the 
quantity.  The Attachment B must be signed by Depositor and delivered to DSI 
with the deposit materials.  Unless and until Depositor makes the initial 
deposit with DSI, DSI shall have no obligation with respect to this 
Agreement, except the obligation to notify the parties regarding the status 
of the deposit account as required in Section 2.2 below.

1.3 DEPOSIT INSPECTION.  When DSI receives the deposit materials and the 
Attachment B, DSI will conduct a deposit inspection by visually matching the 
labeling of the tangible media containing the deposit materials to the item 
descriptions and quantity listed on the Attachment B. In addition to the 
deposit inspection, Preferred Beneficiary may elect to cause a verification 
of the deposit materials in accordance with Section 1.6 below.

1.4 ACCEPTANCE OF DEPOSIT.  At completion of the deposit inspection, if DSI 
determines that the labeling of the tangible media matches the item 
descriptions and quantity on Attachment B, DSI will date and sign the 
Attachment B and mail a copy thereof to Depositor and Preferred Beneficiary.  
If DSI determines that the labeling does not match the item descriptions or 
quantity on the Attachment B, DSI will (a) note the discrepancies in writing 
on the Attachment B; (b) date and sign the Attachment B with the exceptions 
noted; and (c) provide a copy of the Attachment B to Depositor and Preferred 
Beneficiary.  DSI's acceptance of the deposit occurs upon the signing of the 
Attachment B by DSI.  Delivery of the signed Attachment B to Preferred 
Beneficiary is Preferred Beneficiary's notice that the deposit materials have 
been received and accepted by DSI.

1.5 DEPOSITOR'S REPRESENTATIONS.  Depositor represents as follows:

    a.   Depositor lawfully possesses all of the deposit materials deposited
         with DSI;

    b.   With respect to all of the deposit materials, Depositor has the right
         and authority to grant to DSI and Preferred Beneficiary the rights as
         provided in this Agreement;

    c.   The deposit materials are not subject to any lien or other
         encumbrance; and

                            Value Added Reseller Agreement

    d.   The deposit materials consist of the proprietary information and other
         materials identified either in the license agreement or Attachment A,
         as the case may be.

1.6 VERIFICATION.  Preferred Beneficiary shall have the right, at Preferred 
Beneficiary's expense, to cause a verification of any deposit materials.  A 
verification determines, in different levels of detail, the accuracy, 
completeness, sufficiency and quality of the deposit materials.  If a 
verification is elected after the deposit materials have been delivered to 
DSI, then only DSI, or at DSI's election an independent person or company 
selected and supervised by DSI, may perform the verification.

1.7 DEPOSIT UPDATES.  Unless otherwise provided by the license agreement, 
Depositor shall update the deposit materials within 60 days of each release 
of a new version of the product which is subject to the license agreement.  
Such updates will be added to the existing deposit.  All deposit updates 
shall be listed on a new Attachment B and the new Attachment B shall be 
signed by Depositor.  Each Attachment B will be held and maintained 
separately within the escrow account.  An independent record will be created 
which will document the activity for each Attachment B. The processing of all 
deposit updates shall be in accordance with Sections 1.2 through 1.6 above.  
All references in this Agreement to the deposit materials shall include the 
initial deposit materials and any updates.

1.8 REMOVAL OF DEPOSIT MATERIALS.  The deposit materials may be removed 
and/or exchanged only on written instructions signed by Depositor and 
Preferred Beneficiary, or as otherwise provided in this Agreement.

ARTICLE 2 -- CONFIDENTIALITY AND RECORD KEEPING

2.1 CONFIDENTIALITY.  DSI shall maintain the deposit materials in a secure, 
environmentally safe, locked receptacle which is accessible only to 
authorized employees of DSI.  DSI shall have the obligation to reasonably 
protect the confidentiality of the deposit materials.  Except as provided in 
this Agreement, DSI shall not disclose, transfer, make available, or use the 
deposit materials. DSI shall not disclose the content of this Agreement to 
any third party.  If DSI receives a subpoena or other order of a court or 
other judicial tribunal pertaining to the disclosure or release of the 
deposit materials, DSI will immediately notify the parties to this Agreement. 
 It shall be the responsibility of Depositor and/or Preferred Beneficiary to 
challenge any such order; provided, however, that DSI does not waive its 
rights to present its position with respect to any 


                                          D(3)

tribunal order. (See Section 7.5 below for notices of requested orders.)

report profiling the account history at least semi-annually.  DSI may provide 
copies of the account history pertaining to this Agreement upon the request 
of any party to this Agreement.

2.3 AUDIT RIGHTS.  During the term of this Agreement, Depositor and Preferred 
Beneficiary shall each have the right to inspect the written records of DSI 
pertaining to this Agreement.  Any inspection shall be held during normal 
business hours and following reasonable prior notice.

ARTICLE 3 -- GRANT OF RIGHTS TO DSI

3.1 TITLE TO MEDIA.  Depositor hereby transfers to DSI the title to the media 
upon which the proprietary information and materials are written or stored. 
However, this transfer does not include the ownership of the proprietary 
information and materials contained on the media such as any copyright, trade 
secret, patent or other intellectual property rights.

3.2 RIGHT TO MAKE COPIES.  DSI shall have the right to make copies of the 
deposit materials as reasonably necessary to perform this Agreement.  DSI 
shall copy all copyright, nondisclosure, and other proprietary notices and 
titles contained on the deposit materials onto any copies made by DSI.  With 
all deposit materials submitted to DSI, Depositor shall provide any and all 
instructions as may be necessary to duplicate the deposit materials including 
but not limited to the hardware and/or software needed.

3.3 RIGHT TO SUBLICENSE UPON RELEASE.  As of the effective date of this 
Agreement, Depositor hereby grants to DSI a non-exclusive, irrevocable, 
perpetual, and royalty-free license to sublicense the deposit materials to

         the license agreement; or

    b.   Depositor's failure to continue to do business in the ordinary course.

4.2 FILING FOR RELEASE.  If Preferred Beneficiary believes in good faith that 
a Release Condition has occurred, Preferred Beneficiary may provide to DSI 
written notice of the occurrence of the Release Condition and a request for 
the release of the deposit materials.  Upon receipt of such notice, DSI shall 
provide a copy of the notice to Depositor, by certified mail, return receipt

continuing the benefits afforded to Preferred Beneficiary by the license 
agreement.  Preferred Beneficiary shall be obligated to maintain the 
confidentiality of the released deposit materials.

in full by DSI within one month of the date of such notice, then DSI shall 
have the right to terminate this Agreement at any time thereafter by sending 
written notice of termination to all parties.  DSI shall have no obligation

remains unpaid.

5.3 DISPOSITION OF DEPOSIT MATERIALS UPON TERMINATION.  Upon termination of 
this Agreement by joint instruction of Depositor and Preferred Beneficiary, 
DSI shall destroy, return, or otherwise deliver the deposit materials in 
accordance with Depositor's instructions.  Upon termination for nonpayment,

materials if the deposit materials are subject to another escrow agreement 
with DSI.

Agreement, the following provisions of this Agreement shall survive:

For any service not listed on DSI's standard fee schedule, DSI will provide a

6.2 PAYMENT TERMS.  DSI shall not be required to perform any service unless 
the payment for such service and any outstanding balances owed to DSI are

the reasonable control of DSI.

7.2 INDEMNIFICATION.  DSI shall be responsible to perform its obligations 
under this Agreement and to act in a reasonable and prudent manner with

actions, damages, arbitration fees and expenses, costs, attorney's fees and 
other liabilities incurred by DSI relating in any way to this escrow

7.4 CONTROLLING LAW.  This Agreement is to be governed and construed in 
accordance with the laws of the State of California, without regard to its 
conflict of law provisions.

7.5 NOTICE OF REQUESTED ORDER.  If any party intends to obtain an order from 
the arbitrator or any court of competent jurisdiction which may direct DSI to 
take, or refrain from taking any action, that party shall:

    a.   Give DSI at least two business days' prior notice of the hearing;

    b.   Include in any such order that, as a precondition to DSI's obligation,
         DSI be paid in full for any past due fees and be paid for the
         reasonable value of the services to be rendered pursuant to such
         order; and

    c.   Ensure that DSI not be required to deliver the original (as opposed to
         a copy) of the deposit materials if DSI may need to retain the
         original in its possession to fulfill any of its other duties.

                                 SOURCE CODE ADDENDUM


    Etak, Inc. ("Etak") and Teletrac ("USER") agree that USER shall have 
access to and use of certain Etak Software "Software") source code in 
accordance with the terms and conditions of this Addendum ("Addendum").

1.  DELIVERY OF SOURCE.  Upon execution of this Addendum by both parties, 
Etak shall deliver to USER source code for Etak Software ("Source"), as 
specified in Attachment A to this Addendum.  USER shall be entitled to retain 
and use Source only if USER continues to fully comply with all of USER's 
obligations under the USER Agreement.

2.  LICENSE.  Etak hereby grants to USER, subject to the terms and conditions 
of this Addendum, a nontransferable, non-exclusive license to (i) load Source 
on a single CPU at USER's primary business facility in the United States; and 
(ii) permit up to three (3) "Designated Employees" of USER to access and use 
Source for the sole purpose of "porting" Source to a specified single target 
"platform."  The single target platform is specified in Attachment A. 
"Designated Employee" shall mean a full-time employee of USER who has signed 
a non-disclosure agreement with respect to use, confidentiality, security and 
other restrictions regarding Source that is consistent with this Addendum.  
USER shall indicate on Attachment A the name and title of the Designated 
Employees. "Porting" shall mean using Source to create object code that is 
executable on the target platform and that duplicates the functionality of 
Source (the "Ported Code").  "Platform" shall mean a combination of hardware 
and operating system. Upon termination of this Addendum, USER shall return 
Source and all copies thereof to Etak and shall certify in writing that USER 
has done so and that USER shall make no further use of Source.

Etak also hereby grants to USER, subject to the terms and conditions of this 
Addendum, a non-transferable, non-exclusive license (valid as long as the 
USER Agreement is in effect) to sublicense the Ported Code to End Users as a 
Licensed Product under the terms and conditions of the USER Agreement, as 
modified by this Addendum.  However, USER shall not sublicense the Ported 
Code separately, but only in combination with application software created by 
USER.  All Ported Code shall be considered a Derivative Product under the 
terms of the USER Agreement.  USER agrees to provide to Etak a complete and 
correct copy of the Ported Code and the "makefile file" used to create the 
Ported Code, as well as all associated documentation used in the Porting, 
promptly upon creation thereof.  However, Etak agrees that it will not 
provide a copy of the Ported Code to any third party unless Etak has first 
generally released the Ported Code as an Etak Product, in which case Etak may 
provide the Ported Code

                     to a Request for Confidential Treatment.]


                                      Etak, Inc.
                            Value Added Reseller Agreement

to any third party in accordance with Etak's standard distribution practices.

USER agrees not to use Source for any purpose except as specifically 
permitted above in this Section 2.  By way of example, and not by way of 
limitation, USER shall not reverse engineer, analyze, or modify Source 
(except for modifications that are necessary to create operational Ported 
Code), nor shall USER rent, disclose, publish, sell, assign, lease, 
sublicense, market, or transfer Source to any third party.  USER shall not 
ship, load or use Source outside the United States.  Etak shall provide to 
USER source code only for Etak Software as specified in Attachment A, and not 
for any other Etak software.

3.  PROTECTION OF SOURCE.  USER acknowledges that Source is the unpublished, 
copyrighted work of Etak, contains valuable trade secrets, and Etak reserves 
all rights in the Source not expressly granted to USER by this Addendum.  
USER shall not publish or permit others to publish Source.  No title to or 
ownership of Source is hereby transferred to USER.  USER's rights shall at 
all times be subject to the use, non-disclosure and other restrictions 
contained in this Addendum

USER agrees that Source shall not be duplicated, copied, manufactured or 
reproduced in any manner, except for a single archival backup copy.  USER 
agrees to mark the original and the archival copy with a human-readable 
legend stating (i) "CONFIDENTIAL TO AND PROPERTY OF ETAK, INC."; (ii) 
"SUBJECT TO USE RESTRICTIONS IN ETAK, INC.  LICENSE AGREEMENT"; and (iii) 
"COPYRIGHT ETAK, INC. 1984-1997." USER shall not remove or alter such marking.

Source, including all aspects thereof, together with all materials and 
knowledge related thereto (the "Confidential Items"), are obtained by USER, 
and its employees, agents and representatives, in confidence and in trust and 
except as expressly permitted by this Addendum, shall not be used, duplicated 
or disclosed by any of them in any form for the use or benefit of any person 
or entity, nor reproduced, transcribed, imitated or simulated in whole or in 
part.  USER shall take all reasonable steps to ensure that the Confidential 
Items are not disclosed or duplicated in contravention of this Addendum, to 
maintain the confidentiality of Confidential Items and to protect 
Confidential Items from misappropriation or misuse, unauthorized duplication 
or distribution, including without limitation the exercise by USER of at 
least the same degree of care USER employs in protecting its own most 
valuable confidential information.  USER shall notify Etak promptly if USER 
learns of any misappropriation of the Confidential Items or use of the 
Confidential Items by anyone in any manner not expressly authorized by this 
Addendum, and shall fully

cooperate with any efforts by Etak to prevent any misappropriation or misuse 
of Confidential Items.

USER agrees that money damages are inadequate to protect Etak's rights under
this Addendum and that Etak shall be entitled to specific performance to protect
its rights hereunder, in addition to any other remedies to which it may be
entitled.

OF WARRANTY, NEGLIGENCE, STRICT LIABILITY, MISREPRESENTATION, AND OTHER TORTS. 
USER FURTHER AGREES THAT ETAK SHALL NOT BE LIABLE IN ANY EVENT FOR ANY DAMAGES
INCURRED BY USER OR BY ANY OTHER PERSON, ORGANIZATION OR ENTITY AS A RESULT OF
USER'S MISUSE OF SOURCE.  NOR SHALL ETAK BE LIABLE FOR ANY CLAIM OR DEMAND
AGAINST USER BY ANY OTHER PERSON, ORGANIZATION OR ENTITY.  ETAK SHALL NOT BE
LIABLE TO USER BECAUSE OF ANY EXPIRATION, TERMINATION OR FAILURE TO RENEW OR
