If Teletrac, in good faith, disputes any invoice, in whole or in part, either as
to the fees and charges set forth therein or on account of the failure of such
invoice to give Teletrac the full amount of any credits or set-offs to which
Teletrac believes it is entitled, Teletrac shall not be deemed in breach or
default or Material Default under this Agreement, provided that: (a) Teletrac
shall pay to Tadiran the undisputed net amount; (b) Teletrac shall pay the
balance of the invoice into an escrow account with an independent third party,
to be held pending resolution of the dispute; (c) Teletrac shall give Tadiran a

such disputed amount(s) are determined to have been properly charged by Tadiran,
the escrowee shall promptly remit to Tadiran such disputed amount, plus any
interest earned thereon while in escrow. Notwithstanding the foregoing, Teletrac
shall not dispute any invoice, nor pay any amounts thereof unto escrow rather
than to Tadiran, on the basis of a claim of defect as to any Prototype that has
already been accepted by Teletrac pursuant to Section 2.2, and all amounts
already paid into escrow on account of such dispute shall be released to Tadiran
upon such acceptance.

6.4. Taxes and Duties.

Tadiran shall be responsible for payments of all taxes, duties, customs, etc.
payable in Israel in respect of this Agreement or the transactions hereunder.
Teletrac shall be responsible for payments of all taxes, duties, customs, etc.
payable in the U.S.A. in respect of this Agreement or the transactions
hereunder, provided, however, that each party shall be responsible for
presenting to the other copies of the invoices for all such taxes and duties and
shall cooperate with the other's legal efforts to minimize any such taxes,
customs, and duties. Further, each party shall defend and indemnify the other
against all claims in respect of any taxes, customs, and duties for which it is
responsible.

6.5. Delay.

In the event that Teletrac fails to make any payment to Tadiran (or into escrow,
in the case of disputed payments) within the time frame specified in this
Agreement, then, in addition to any other remedies available to Tadiran,
Tadiran's deadlines and milestones under the Project

                                       5


Schedule shall be automatically extended for a period equal to the delay (beyond
the permitted time frame) in Teletrac's making the required payment.

6.6. Interest.

In the event that either Party fails to make any undisputed payment to the other
Party within the time frame specified in this Agreement, then, in addition to
any other remedies available in respect of such failure, such Party shall pay
the other Party interest on the unpaid amount calculated at a rate equal to one
percent (1%) per month, beginning on the date on which such amount became due
and payable. In the event and to the extent that any disputed payment allegedly
owed by either party is determined to be properly due and owing, then such party
shall promptly remit the disputed amount to the other party, plus interest
calculated at a floating rate equal to two percent (2%) plus the "prime rate"
(calculated per annum) as published in the "Wall Street Journal" on the first
business day of each month during which such amount remains unpaid, beginning
with the month in which such disputed amount was properly invoiced.

7. PURCHASE COMMITMENT

Tadiran shall be capable of delivering the IBSU's to Teletrac in production
quantities within sixty (60) days after acceptance by Teletrac of the Prototypes
provided Teletrac, based upon scheduling requirements specified by Tadiran, has
ordered IBSU units sufficiently in advance in order to provide commercially
reasonable lead times for procurement of materials. From and after the date upon
which Tadiran is able to begin full production of the IBSU, provided that
Tadiran has timely performed all of its obligations under this Agreement at such
time and that all of Prototypes of the components have been accepted by
Teletrac, Teletrac will purchase from Tadiran all of the units (including all
desired associated modules) that Teletrac may require, until Teletrac has
acquired 1,500 units or (if occurring later) until the end of the 22nd calendar
month after the month in which Tadiran delivered the first production units to
Teletrac. Thereafter, Teletrac may purchase its requirements from other
suppliers than Tadiran, provided that:

(a) Teletrac shall give Tadiran the opportunity to bid on any such requirements;
and
(b) on purchases from other suppliers, Teletrac shall pay to Tadiran a royalty
of $2,500 U.S. per IBSU unit (including any modules) produced from Tadiran's
IBSU Production Package.

In furtherance of the above, upon the later to occur of the two events described
above (the acquisition of 1,500 units or the end of said 22nd calendar month):
(i) Tadiran shall provide Teletrac (and Teletrac may provide other suppliers it
may designate) the production license as may be needed, including the IBSU
Production Package and all other documents and specifications necessary, for the
manufacturing of IBSUs for Teletrac (but for no other purposes); and (ii) the
IBSU Production Package shall be delivered to Teletrac by the Escrow Holder.

12.3. Injunctive Relief. Each party acknowledges and agrees that any violation
of this Section 12 would cause irreparable injury for which the injured party
would have no adequate remedy at law, and that the injured party shall be
entitled to preliminary and other injunctive relief against the other party for
any such violation. Such injunctive relief shall be in addition to, and in no
way in limitation of, any and all other remedies or rights that the injured
party shall have at law or in equity. The provisions of this Section 12 shall
survive any termination of this Agreement.

13. DISPUTE RESOLUTION

13.1. Escalation Procedures.

Except for Problems that are governed by Section 12.3 hereof, to the extent
practical and not as a limitation to either parties' rights under Section 14
below, if any dispute arises between the parties, and after good faith
negotiations, the parties disagree as to the existence or its solution, the
party raising the issue shall promptly provide written notice to the other. Each
party shall promptly forward the disputed matter to an executive officer of such
party that is not otherwise directly associated with this Agreement (the
"Executive Team"). All decisions of the Executive Team shall be made on a
unanimous basis, and shall be binding with Tadiran and Teletrac. If the
Executive Team cannot resolve a dispute within fifteen (15) days after having
been referred such dispute (and without regard to whether either party has
contested whether these procedures, including the duty of good faith, have been
followed), each party shall have the right to commence an arbitration, as set
forth in Section 13.2. No party shall be obligated to this provision for
breaches of Section 12 hereof.

13.2. Arbitration. In the event of any dispute, controversy or disagreement
regarding performance under or interpretation of this Agreement that is not
resolved pursuant to Section 13.1, the Parties agree that the dispute,
controversy or disagreement shall be submitted to arbitration using the
then-current Commercial Arbitration Rules of the American Arbitration
Association (the "AAA Rules"); provided, however, that disputes, controversies
or disagreements regarding Section 12 shall not be subject to arbitration.
Notwithstanding the foregoing, and the then-current AAA Rules: (a) the
arbitration proceeding shall be conducted by a single arbitrator, to be chosen
by mutual agreement of a designee chosen by Teletrac and a designee chosen by
Tadiran (if such designees are unable to agree on the choice of an arbitrator,
then such arbitrator shall be selected in accordance with the then-current AAA
Rules); (b) in order to be eligible to serve as an arbitrator, the arbitrator
must have a minimum of five years experience in telecommunications activities
during the eight years immediately preceding the dispute; (c) the existence,
subject, evidence, proceedings, and ruling resulting from the arbitration
proceeding shall be deemed Confidential Information, and shall not be disclosed
by either party, their representatives or the arbitrators (except as may be
necessary to enforce the arbitration award by the court); (d) the proceedings
shall take place in New York, New York; (e) the arbitrator shall be required to
prepare written findings of fact, together with a written award specifying its
ruling; and (f) subject to the terms and conditions of this Agreement, the
arbitrator's award may grant any remedy or relief which the arbitrator deems
just and equitable. Each party shall bear its own arbitration costs and
expenses, (including without limitation the costs and expenses of the arbitrator
selected by it and fifty percent (50%) of the costs and expenses of a third
arbitrator), provided, however, that the arbitrators may modify the allocation
of fees, costs and expenses in the award in those cases where fairness dictates
other than an equal

                                       10



allocation between the parties. The award shall be final and binding on the
parties, and judgment on the award may be entered in and enforced by any court
of competent jurisdiction.

13.3. No Termination or Suspension of Services.

Notwithstanding anything to the contrary contained herein, if any Problem or
dispute arises between the parties, whether or not it requires at any time the
use of the escalation procedures described above, in no event nor for any reason
and unless and until authorized by a court of competent jurisdiction, shall
Tadiran stop performing its obligations hereunder, disable the IBSU or any other
equipment or software, or perform any other action that prevents, slows down, or
reduces in any way the performance of the IBSU or any of Tadiran's obligations
hereunder or Teletrac's ability to perform its business; provided, however, that
the foregoing shall not apply if Teletrac fails to make any payment as and when
due hereunder (subject to the provisions of Section 6.3 hereof), and fails to
cure such failure within thirty (30) days after the due date of the invoice.

14.  DEFAULT

14.1  Material Default.  A "Material Default" shall be deemed to have occurred
under this Agreement if:

14.1.1. Failure to Develop IBSU. Tadiran fails to meet its obligations to
develop the IBSU in accordance with the Specifications or the Project Schedule,
on the terms and conditions set forth in Section 3 (subject to the provisions
for cure and re-submission under Section 2.2).

14.1.2. Failure to Make Payments. Teletrac fails to make any payment as and when
due hereunder (subject to the provisions of Section 6.3 hereof), and fails to
cure such failure within thirty (30) days after the due date of the invoice.

14.1.3. Breach of Confidentiality. Either party breaches its obligation to the
other party under Section 12, and fails to cure such breach within five (5) days
after the party has received notice of such breach (if capable of cure).

14.1.4. Other Failures to Perform. Either party fails, neglects or refuses to
duly observe or perform any other material obligation, covenant or condition
under this Agreement and, in cases where the breach does not involve the
violation of a law, the breaching party fails to cure such breach within thirty
(30) days after the breaching party has received notice of such breach.

14.1.5. Breach of Representation or Warranty. Any representation or warranty
made in this Agreement by any party is discovered to be materially false.

14.1.6. Insolvency. A party becomes insolvent, generally fails to pay its debts
as they become due, enters into receivership or any arrangement or composition
with creditors generally, is the subject of a voluntary or involuntary petition
or other action or proceeding for bankruptcy or reorganization or dissolution or
winding-up or makes an assignment for the benefit of creditors, or ceases to do
business as a going concern, or, a substantial part of a party's property is, or
becomes, subject to any levy, seizure, assignment or sale, for or by any
creditor or governmental agency without being released or satisfied within
thirty (30) days thereafter. For purposes of this

                                       11




Section 14.1, references to "a party" shall, in the case of Tadiran, be deemed
references to Tadiran Ltd. (the parent corporation of Tadiran), rather than to
Tadiran Telematics Ltd.

14.2. Force Majeure. Neither party shall be liable for delays or failure in
performance that result from acts of God, acts of governmental or military
authority, fires, floods, epidemics, riot, war, terrorist or enemy act, strikes,
labor disturbances, or general call-up of military reserves ("Force Majeure
Event"), provided that the party experiencing the delay immediately notifies the
other party of the delay and its anticipated duration. If a party suffers a
Force Majeure Event, its affected obligations shall be deemed suspended until
the Force Majeure Event has ended and a reasonable period of time for overcoming
the effects thereof has passed. Both parties shall use reasonable efforts to
minimize delays that occur due to a Force Majeure Event.

14.3. Remedies.

14.3.1. Teletrac's Remedies. If Tadiran shall commit a Material Default under
this Agreement, or in the event that the delay or interruption of performance
resulting from a Force Majeure Event, as provided in Section 14.2, exceeds
ninety (90) days, Teletrac, subject to the provisions of Section 13 hereof,
shall have the following rights and remedies, none of which is exclusive and any
or all of which may be pursued:

(a) Teletrac shall be entitled to terminate this Agreement, by providing Tadiran
with a written notice to this effect.

(b) In case of a Material Default, Teletrac shall be entitled to suspend payment
of any fees due and owing to Tadiran for up to ninety (90) days or until Tadiran
earlier cures such Default or until Teletrac shall earlier elect to terminate
this Agreement, and Teletrac shall be entitled to all other remedies that may be
available to it under law or in equity. Teletrac's damages shall be limited to a
refund of the development price paid to Tadiran and shall not include any
incidental, exemplary, punitive or consequential damages (including lost
profits); provided, however that: (i) these limitations on the amount and the
types of Teletrac's damages shall not apply in the event that Tadiran has acted
in a commercially unreasonable manner, with negligence in the performance of its
obligation, or in bad faith, nor shall they apply to claims based upon Section
12 hereof; (ii) said limitations on the amounts and types of damages shall not
apply to claims based upon the provision of IBSUs in violation of the provisions
of Section 9 hereof; and (iii) with respect to breaches of Section 11 hereof,
the amount of damages shall be limited to $4,550,000 but there shall be no
limitations upon the types of damages and, in the event of a breach of Section
11.1.2, Tadiran shall promptly make appropriate modifications to the subject
properties to make them non-infringing.

14.3.2. Tadiran's Remedies. If Teletrac shall commit a Material Default under
this Agreement, Tadiran, subject to Section 13 hereof, shall be entitled to
terminate this Agreement, by providing Teletrac with a written notice to this
effect, and Tadiran shall have all the other remedies that may be available to
it under law or in equity.

14.4. Termination Obligations. Upon termination of this Agreement for a Material
default by Tadiran, Tadiran, and the Escrow Holder under the Escrow Agreement
described in Section 2.3, shall each promptly deliver to Teletrac a copy of the
IBSU Production Package (at whatever state

                                       12


of completion, if not completed). In the case of a Material Default of a type
identified in Section 14.1.6., Tadiran and the Source Code Escrow Holder shall
each deliver to Teletrac a copy of the IBSU source code (at whatever state of
completion) held by said escrow holder pursuant to Section 2.3.

15. NOTICES

provided for, or given under this Agreement, shall be in writing, and will be

16. MISCELLANEOUS

16.1. Entire Agreement. Except as expressly stated herein, this Agreement
constitutes the entire understanding and agreement between the parties with
respect to the transactions contemplated herein, and supersedes any and all
prior or contemporaneous, oral or written communication with respect to the
subject matter hereof, all of which are merged herein. No usage of trade, or
other regular practice or method of dealing between the parties hereto or
others, will be used to

                                       13


modify, interpret, supplement, or alter in any manner the express terms of this
Agreement. Neither party shall be deemed the draftsperson of this Agreement, for
the purpose of the rule that the ambiguities in a contract shall be construed
against the draftsperson.

16.2. Governing Law. This Agreement and the performance of the parties hereunder
shall be governed and construed in accordance with the substantive laws of the
State of New York, without regard to any conflict of laws.

16.3. Captions; Counterparts; Section Numbers. Captions, Tables of Contents, and
Schedule Titles are used herein for convenience only and will not be used in the
construction or interpretation of this Agreement. This Agreement may be executed
in more than one counterpart, in which case all of them shall be deemed one and
the same Agreement (provided that there exists at least one counterpart that has
been executed by both parties). Any reference herein to a particular Section
number (e.g., "Section 5.2"), shall be deemed a reference as well to all
Sections that bear sub-numbers to the number of the referenced Section (e.g.,
Sections 5.2.1, 5.2.2.1, etc.).

16.4. Non-Assignment.

16.4.1. Teletrac
This Agreement and any interest therein, and any of the rights and obligations
of Teletrac hereunder, may be directly or indirectly assigned, sold or otherwise
disposed of by Teletrac without the prior written consent of Tadiran; provided,
however, that no such assignment, sale, or other disposition shall release or
discharge Teletrac from any of its duties and obligations hereunder. No such
assignment, sale, or disposition shall be valid unless the transferee agrees in
writing to be bound by this Agreement.

16.4.2.  Tadiran

Neither this Agreement, nor any interest in the rights of Tadiran hereunder, may
be directly or indirectly assigned, sold or otherwise disposed of by Tadiran.
Tadiran may not directly or indirectly subcontract or delegate any of its
obligations under this Agreement to third parties, except with Teletrac's prior
written approval, which shall be given only in the exercise of Teletrac's sole
discretion. If such consent is granted, Tadiran shall be responsible for
supervising the activities and performance of each subcontractor and shall be
jointly and severally responsible with each subcontractor for any act or failure
to act of such subcontractor. If Teletrac determines that the performance or
conduct of any Tadiran subcontractor is unsatisfactory, Teletrac shall notify
Tadiran of its determination in writing, indicating the reasons therefor.
Tadiran shall promptly take all necessary actions to immediately remedy the
performance or conduct of such contractor or to replace such contractor by
another third party or by Tadiran personnel.

16.5. Amendments; Waivers. Except as provided expressly herein, this Agreement
shall not be modified, amended or in any way altered except by written document
signed by both of the parties hereto. No waiver of any provision of this
Agreement, or of any rights or obligations of any party hereunder, shall be
effective unless in writing and signed by the party waiving compliance, and such
waiver shall be effective only in the specific instance, and for the specific


                                       14


purpose, stated in such writing. No waiver of breach of, or default under, any
provision of this Agreement shall be deemed a waiver of any other provision, or
of any subsequent breach or default of the same provision, of this Agreement.

16.6. Legal Status of Parties. This Agreement shall not be construed to
constitute any of the parties as a representative, agent, employee, partner, or
co-venturer of any other party. Tadiran shall be an independent contractor for
the performance under this Agreement. Tadiran shall not have the authority to
enter into any agreement, or to assume any liability, on behalf of Teletrac, or
to bind or commit Teletrac in any manner. Teletrac shall have no power to
supervise, give directions, or otherwise regulate, Tadiran's operations or its
employees. Tadiran shall assume full responsibility for payment of all federal,
state, local, and other taxes or contributions imposed or required under
unemployment insurance, social security, income tax, or similar laws with
respect to such persons.

16.7. Severability. If any provision of this Agreement is determined to be
invalid or unenforceable, that provision shall be deemed stricken, and the
remainder of the Agreement shall continue in full force and effect insofar as it
remains a workable instrument to accomplish the intent and purposes of the
parties. The parties further agree to replace the severed provision with the
provision that will come closest to reflecting the intention of the parties
underlying the severed provision but that will be valid, legal and enforceable.

16.8. Survival of Rights and Obligations. To the extent appropriate in context,
the rights and obligations of the parties under this Agreement shall survive and
continue after the termination of this Agreement for any reason, and shall bind
the parties and their legal representatives, successors, heirs, and assigns.

16.9. Schedules. The Schedules attached hereto or incorporated herein by
reference are an integral part of the Agreement. To the extent that there are
any conflicts between the terms and conditions in the Schedules and those
contained herein, the terms and conditions set forth herein shall control.

16.10. Expenses. Each party will bear all of its own costs and expenses
(including attorneys' fees) incurred in connection with this Agreement and the
transactions contemplated hereby.

16.11. Remedies. Time is of the essence of this Agreement.

                           PREFERRED ESCROW AGREEMENT

                        Account Number _________________

This Agreement is effective ________________, 19___ among Data Securities
International, Inc. ("DSI"), Tadiran Telematics Ltd. ("Depositor") and Teletrac

Agreement as "the parties."

A. Depositor and Preferred Beneficiary have entered or will enter into an
Integrated Base Station Unit Development 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. After acceptance of the last of the Prototypes,
and at least thirty (30) days before shipment of the first production order,
Depositor shall deliver to DSI the IBSU Production Package, which shall consist
of all information necessary for the manufacture of the IBSU not including RSSW,
including but not limited to: (a) schematic or other drawings or diagrams
representing the circuitry of the IBSU, with devices and parts with part numbers
cross-referenced to the bill of materials and with all respective connections
shown; (b) a bill of materials that lists all parts and devices with part

resistors and capacitors; (c) documentation of mechanical drawings with
specifications for any unique plastic parts; (e) master artwork, drill charts,
packaging and fabrication notes for printed circuit boards; and (f) complete
object code files, except RSSW, for all computer programs that are a part of, or
are used in connection with, the IBSU, along with all associated technical
documentation.

1.2 Identification of Tangible Media. Prior to the delivery of the deposit
materials to DSI, Depositor shall conspicuously label for identification each
document, magnetic tape, disk, or other tangible media upon which the deposit
materials are written or stored. Additionally, Depositor shall complete Exhibit
A to this Agreement by listing each such tangible media by the item label
description, the type of media and the quantity. The Exhibit A must be signed by


                                       24



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 Exhibit
A, 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 Exhibit A.

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 Exhibit A, DSI will date and sign the Exhibit A 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 Exhibit A, DSI
will (a) note the discrepancies in writing on the Exhibit A; (b) date and sign
the Exhibit A with the exceptions noted; and (c) provide a copy of the Exhibit A
to Depositor and Preferred Beneficiary. DSI's acceptance of the deposit occurs
upon the signing of the Exhibit A by DSI. Delivery of the signed Exhibit A 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. 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;

b. The deposit materials are not subject to any lien or other encumbrance.

1.6 Inspection. At the time Depositor shall notify Preferred Beneficiary that
the IBSU Production Package is ready for deposit with DSI, Depositor shall allow
Preferred Beneficiary to inspect the IBSU Production Package prior to the
deposit, so as to allow Preferred Beneficiary to ascertain that said package
conforms to the provisions of Section 2.3 of the License Agreement.

1.7 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.

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 such order. DSI will not be required to disobey any court or other
judicial tribunal order. (See Section 7.5 below for notices of requested
