ITEM 1 - BUSINESS

General

LoJack Corporation ("LoJack" or the "Company") was organized as a Massachusetts
corporation in 1978.  Its telephone number is (617) 326-4700.

LoJack developed and markets the LoJack System, a unique, patented system
designed to assist law enforcement personnel in locating, tracking and
recovering stolen vehicles.  In addition, LoJack developed and markets
CarSearch, a product line of its patented LoJack System, designated for use in
international markets where it may not be practicable or desirable to implement
the fully integrated LoJack System.

The LoJack System is comprised of a Registration System maintained and operated
by LoJack; a Sector Activation System and Police Tracking Computers operated by
law enforcement officials (the "Law Enforcement Components"); and the LoJack
Unit, a VHF (very high frequency) transponder sold to consumers.  The LoJack
System is designed to be integrated into existing law enforcement computers and
telecommunication networks and procedures.  If a car equipped with a LoJack Unit
is stolen, its owner reports the theft as usual to the local police department.
Existing law enforcement computer and communication networks and procedures
operate in the normal manner for a report of a stolen vehicle.  If the theft
involves a vehicle equipped with a LoJack Unit, a unique radio signal will be
transmitted automatically to the LoJack Unit in the stolen vehicle activating
its tracking signal.  The tracking signal emitted from the LoJack Unit can be
detected by the Police Tracking Computer installed in police patrol cars and
aircraft throughout the coverage areas and used to lead law enforcement officers
to the stolen vehicle.  The Company also sells conventional vehicle security
devices, which may be purchased as options with the LoJack Unit, under the names
"LoJack Prevent" and "LoJack Alert."

Operation of the LoJack System in the United States

Under agreements with state police agencies, LoJack generally furnishes the Law
Enforcement Components for distribution to state, county, and municipal law
enforcement agencies for a nominal rent.  The installation, testing and
maintenance of the Law Enforcement Components are primarily the responsibility
of LoJack.  The Law Enforcement Components are generally owned by LoJack or a
LoJack  subsidiary; the respective state, county or city law enforcement agency
provides the necessary staff to operate the LoJack System as required during the
term of each such agreement.  The agreements with the applicable law enforcement
agencies are generally for initial terms of up to five (5) years. To date, any
such agreements which have expired have been renewed or are in the process of
renewal.  Renewal or extension of any such agreement may be subject to
competitive bidding.

The LoJack System has been implemented in the following domestic jurisdictions
pursuant to agreements with applicable law enforcement agencies:

The Company is presently pursuing negotiations with several law enforcement
agencies in the United States regarding the implementation of the LoJack System
in jurisdictions in addition to those mentioned above.  The Company's strategy
is to expand the LoJack System to those jurisdictions where the combination of
new vehicle sales, population density, and the incidence of vehicle theft is
high.  To date, LoJack has expanded into 15 of the original 16 markets it has
targeted. Certain improvements to the Company's technology and interface with
law enforcement systems have made expansion beyond the 16 targeted states
economically feasible for the Company.  Accordingly, over the next two years the
Company plans to expand to certain jurisdictions which are contiguous to
existing LoJack coverage areas as well as to markets that have increased
incidence of car theft.

The LoJack System

The LoJack System consists of four basic components:

       1.  LoJack Unit              
       2.  Police Tracking Computer 
       3.  Sector Activation System 
       4.  Registration System       

The LoJack Unit.  The LoJack Unit is the consumer component of the LoJack System
and is installed in a purchaser's motor vehicle.  The LoJack Unit consists of a
VHF transponder, a microprocessor based computer, and a modem.  The computer's
memory contains a set of codes unique to the particular LoJack Unit and the
vehicle in which it is installed. The microprocessor activates the Unit's
transmitter upon receipt of its unique activation code from the Sector
Activation System.  Since each LoJack Unit has its own unique activation code
and reply code, the microprocessor responds only upon receipt of the appropriate
code. An activated LoJack Unit will continue to broadcast its reply code until
it receives a properly coded message to stop.  That message is sent after the
police have recovered the vehicle. All transmissions are made on a nationwide
radio frequency allocated by the Federal Communications Commission ("FCC") as a
law enforcement radio service.

Police Tracking Computer.  The Police Tracking Computer ("PTC") is a
sophisticated radio direction finder.  The PTC is used by police to locate and
track activated LoJack Units.  The PTC consists of a radio receiver with a
directional antenna array, doppler signal processor, microprocessor based
computer and a controllable display.  When the PTC detects a LoJack Unit
transmission from a stolen vehicle, it displays the reply code along with
graphic indications of signal strength and the direction toward the stolen
vehicle.  The officer may then radio the reply code to the police dispatcher and
obtain a vehicle description.

The PTC is generally installed in police vehicles.  Modified designs of the PTC
have been developed for use in helicopters, as well as fixed locations such as
toll booths, radio towers, or police communication centers.  Effective tracking
range varies under different topographical and other conditions, from about one
mile to approximately five miles under ideal conditions.

Sector Activation System.  The Sector Activation System ("SAS") is a
computerized system that controls and commands the LoJack System and activates
LoJack Units in stolen vehicles.  It is designed to function with existing law
enforcement computer and telecommunication networks and procedures. Routine and
normal processing of a stolen vehicle report activates the SAS, even if the
person reporting the theft and the officer responding are unfamiliar with the
LoJack System.

The Sector Activation Computer ("SAC") contains a file with up-to-date
information on vehicles equipped with LoJack Units.  This computer works in
conjunction with pre-existing law enforcement computer and communication
systems.  This file contains, for each LoJack equipped vehicle, the vehicle
identification number ("VIN") assigned by the vehicle's manufacturer, and the
activation and reply codes for the LoJack Unit installed in that vehicle.

When the VIN of a stolen vehicle is entered into existing stolen vehicle
reporting systems, it is compared automatically to those contained in the LoJack
file.  When a match occurs, the SAC automatically transmits the appropriate
activation code.  

                                       2
<PAGE>
 
Police officers who have detected the transmissions of an activated LoJack Unit
call into a dispatcher for a description of the transmitting vehicle. After the
vehicle is recovered, the VIN is again entered into the SAC to generate the
appropriate deactivation code and to reset the LoJack Unit for future use.

The SAC controls a network of radio transmitters positioned on sites throughout
the coverage area. The SAC accepts stolen vehicle reports from the state law
enforcement computer and initiates activations and deactivations of LoJack
Units.

Registration System. The Registration System is a proprietary method of
assigning digital codes to be transmitted and received by LoJack Units in such
manner that unique activation codes are permanently correlated with the unique
VIN assigned to the vehicle in which the LoJack Unit has been installed.

Marketing and Distribution of LoJack Units - United States

LoJack's marketing approach in each jurisdiction focuses on franchised new car
dealers who will offer the LoJack Unit as an option on both their new and used
car sales. LoJack also markets conventional vehicle security devices sold under
the names "LoJack Prevent" and "LoJack Alert."

LoJack's sales force routinely visits franchised new car dealers to educate and
train dealership personnel in the benefits of the LoJack System. LoJack's direct
marketing efforts emphasize the benefits to the dealers and their customers of
the LoJack Unit as a purchase option for new and used car buyers. Like other
options, the LoJack Unit can usually be financed conveniently as a part of the
purchase price of the vehicle. LoJack uses direct advertising to consumers to
generate product awareness and demand.

LoJack also has plans to intensify its efforts to market its products directly
to operators of fleet and commercial vehicles.

LoJack maintains full responsibility for installation and warranty service of
LoJack Units sold by the Company both for the convenience of dealers through
whom the LoJack Units are marketed and for LoJack to maintain a high degree of
quality control and security over its technology.

In addition to distributing LoJack Units itself, through its subsidiaries or
licensees, LoJack may consider joint ventures or other cooperative arrangements
to expedite the expansion of the LoJack System. The actual method of
distribution will be determined on a market-by-market basis.

International Operations

The Company also licenses the use of its stolen vehicle recovery system
technology in selected international markets. In connection with its efforts to
expand outside of the United States, the Company has utilized its stolen
recovery vehicle technology to develop the CarSearch Stolen Vehicle Recovery
System ("CarSearch"). Unlike the LoJack System currently operational in the
United States, CarSearch has the flexibility of operating independent of
existing law enforcement communication networks.

The Company targets CarSearch for use by either law enforcement or private
security companies in selected international markets where the implementation of
a fully integrated LoJack System may not be feasible. This new application of
the LoJack technology allows stolen vehicles to be activated, tracked and
recovered without the direct involvement of local police.

Present international license agreements have thus far been denominated in 
U.S. dollars and structured with up-front licensing fees, which may be
substantial and are non-recurring, and provide that the Company will
subsequently either supply components and products at prices to be determined
from time to time and/or receive royalties based upon the licensees' revenues.
It is the Company's intention to continue to license the use of either the
LoJack System or CarSearch in other selected international markets on the same
basis as described above. The Company does not anticipate making any direct
investment in the operations of foreign licensees in the foreseeable future.
However, the Company has been granted an option, exercisable through March 1998,
to purchase up to 5% of the outstanding common stock of its United Kingdom
licensee. The Company generally does not recognize revenues during the period
immediately after entering into an agreement with a licensee. Recognition of
revenues does not generally commence until after the licensee receives any
required governmental approvals, such as frequency allocation for the CarSearch
or LoJack System. The governmental approval process may be time-consuming.

                                       3
<PAGE>
 
As of February 28, 1997, the Company had Licensees operating stolen vehicle
recovery systems using LoJack's technology in the following countries: the
United Kingdom, Slovak Republic, the Czech Republic, Greece, Ecuador, Colombia,
Trinidad and Tobago, Hong Kong, Argentina, Russia, Venezuela, South Africa,
Kenya and Korea. The Company also has entered into agreements to license the use
of LoJack's technology in countries such as Germany, Mexico, Brazil and the
Peoples Republic of China.  The date for commencement of operations in these
countries has not been set, as their ability to operate may be subject to the
licensees obtaining certain governmental approval which may be time consuming or
may not be obtained, as well as adequate financing. The Company is also pursuing
similar agreements for other countries.

Approximately 16% of the Company's revenues in fiscal 1997 were derived from
export revenues.  These revenues were comprised of product sales and licensing
revenues from unaffiliated customers in foreign countries.  Approximately 95% of
the Company's foreign product sales are covered by letters of credit or require
payment in advance from the licensee. (See Note 9 to the Notes to Financial
Statements which are included in LoJack's 1997 Annual Report which is filed as
Exhibit 13 hereto.)

Government Regulation and Approval

In 1989, the FCC put into effect a rule change to allocate frequency 173.075 MHz
for nationwide use by state and local law enforcement agencies for stolen
vehicle recovery systems.  Law enforcement agencies in jurisdictions where the
Company operates have been granted authority by the FCC to use this frequency
for LoJack's stolen vehicle recovery system.

In connection with its domestic operations, the Company must obtain the approval
of law enforcement agencies, as well as executive or legislative bodies, for
implementation of the LoJack System before sales of LoJack Units can commence in
a given jurisdiction.  The approval process may be time consuming and costly and
is subject to considerations generally affecting the process of governmental
decision making.  In some jurisdictions, governmental approval may be terminable
at the convenience of the executive or legislative body.  Any such termination
could have a material effect on future sales in any such jurisdiction.

If LoJack were to seek to charge more than nominal prices for the Law
Enforcement Components, governmental appropriation of funds will be required.
Most government agencies have established, by policy, statute or regulation, a
process requiring competitive bidding for all acquisitions of products and
equipment.  This process may cause delay and expense to the Company.  To date,
the Company has not sought to charge law enforcement agencies more than nominal
prices for the Law Enforcement Components, and does not expect to do so in the
near future.

Automobile Insurance Benefits

Management considers automobile insurance premium discounts to be an inducement
for the purchase of LoJack Units by vehicle owners. The application of insurance
premium discounts, which are generally applied to the vehicle owner's
comprehensive insurance, varies from state to state and, in some cases, from
insurance company to insurance company. For example, insurance regulations in
some states, such as Massachusetts, Rhode Island, New York and New Jersey,
provide for mandated insurance discounts for automobiles protected by automobile
security systems.  In other states, such as California, where the granting of
such discounts is not regulated, the determination is made by individual
insurance carriers. Currently, insurance discounts, which vary from state to
state, and nationally by certain insurance carriers, provide for discounts of up
to 35% on comprehensive insurance premiums for vehicles equipped with a vehicle
recovery and anti-theft device. There is also pending legislation in some states
where the LoJack System is operational which would establish or increase
discounts available to vehicle owners who install the LoJack Unit. Since the
insurance industry is, in general, heavily regulated, the process of seeking
voluntary or mandatory discounts for vehicles may involve significant time and
effort by LoJack.

Product Warranty

LoJack warrants to consumers that the LoJack Unit will be free from defects in
material or workmanship for a period of two years, subject to extension at the
customer's option for an additional charge. LoJack also warrants to purchasers
of LoJack Units that if their LoJack equipped vehicle is stolen within two years
of installation and not recovered within 24 hours from the time that the report
of the theft is reported to the police, LoJack will refund the full purchase
price of the LoJack Unit up to a maximum of $595.

Patents and Trademarks

                                       4
<PAGE>
 
LoJack holds United States Patent Nos. 4,818,998 and 4,908,629, which expire in
2006 and 2007, respectively, covering the LoJack System. The Company also holds
patents in various countries in Europe, Asia, South America, and North America.
Patent protection has also been sought by LoJack in several other countries.
Although management believes the patents have value, there can be no assurance
such patents will effectively deter others from manufacturing and marketing a
stolen vehicle recovery system.  LoJack's name and logo are registered
trademarks in the United States and many foreign countries.

Competition

Several competitors or potential competitors are marketing or have announced the
development of products, including those which are GPS-based, which claim to
have stolen vehicle recovery features which may be directly competitive with the
LoJack System. To the knowledge of management, none are compatible with the
LoJack System and none are proposed to be operated or actively monitored
exclusively by law enforcement agencies as is the LoJack System. Additionally,
most potential competitors require consumers to pay recurring fees for their
service, which LoJack does not.

LoJack markets the LoJack System as a stolen vehicle recovery device.
Management believes, however, that makers of auto theft prevention devices view
the LoJack System as competitive, and, consequently, LoJack believes it faces
competition from companies that sell vehicle security devices.

Some of the competitors and potential entrants into the stolen vehicle recovery
industry may have greater resources than LoJack. In addition, there can be no
assurance that a competitor will not develop a system of theft detection or
recovery, including other stolen vehicle recovery systems that may or may not
require government approvals, that would compete with or be superior to the
LoJack System.

Subcontractors

LoJack has subcontracted the manufacture of the LoJack Units, which is designed
for automated production using surface mounted technology, to Motorola, Inc.
LoJack believes that several companies have the capability to manufacture LoJack
Units using this technology.

LoJack subcontracts with Micrologic, Inc. ("Micrologic") of Waltham,
Massachusetts, to perform a substantial portion of the engineering, design and
implementation of the LoJack and CarSearch Systems in new jurisdictions as well
as to perform certain research and development.  LoJack owns all rights in any
new developments created by Micrologic as a subcontractor of LoJack.

LoJack has granted to Micrologic, through April 2000, the exclusive rights to
assemble Police Tracking Computers. LoJack believes that other companies have
the same capabilities as Micrologic, but that changing to a new subcontractor
for these tasks could involve delays and additional cost to LoJack.

Inventory

LoJack seeks to maintain a 60-day supply of LoJack Units, which it believes is
in line with sales levels and sufficient to rapidly fulfill orders.  The Company
maintains an inventory of certain Law Enforcement Components beyond its current
requirements in order to facilitate expansion into additional domestic markets.

Research and Development

During fiscal years 1997, 1996 and 1995 the approximate amounts spent by LoJack
on company-sponsored research and development activities were $518,000,
$516,000, and $330,000, respectively.

In December 1995, LoJack Venture Corporation, a wholly owned subsidiary of
LoJack and Micrologic entered into a joint venture for the purpose of developing
the next generation of the LoJack Unit and other related exploitable technology.
LoJack Venture Corporation and Micrologic have equal ownership interests in the
joint venture.  The joint venture shall own all technology and other
intellectual property that is developed by the joint venture or by Micrologic
under contract to the joint venture, excluding any improvements on United States
Patents held by LoJack.  The joint venture has granted LoJack exclusive rights,
with the right to sublicense, to make, use and sell all products relating to the
next generation of the LoJack Unit ("LJU III") in exchange for certain royalty
payments based on the number of units sold. The technology contemplated by the
joint venture, the LJU III, is currently undergoing production validation
testing. Barring any unforeseen delays, the Company estimates that this product
could be ready for manufacturing by year end, although the Company can give no
assurances concerning the timing of commercial introduction of the LJU III or
its potential commercial success.

the Company leases various facilities in Massachusetts, New Jersey, Michigan,

to waive the default caused by LVC in connection with its 50% investment in the
Venture without first obtaining the Lender's consent; (iii) to convert the

II.  Waivers.  The Lender hereby agrees to waive:
     -------

     A.  The Event of Default which occurred as of April 24, 1996 because the
Parent formed a new subsidiary, LoJack Venture Corporation, a Massachusetts
corporation, without first obtaining Lender's consent in accordance with Section
7.7 of the Loan Agreement; and

     B.  The Event of Default which occurred as of December 1, 1996 because the
Parent caused its wholly-owned subsidiary, LVC, to invest in 50% of the Venture,
without first obtaining Lender's consent in accordance with Section 7.7 of the
Loan Agreement.

     The foregoing waivers are limited to their express terms and shall not be
deemed to be waivers of any other Event of Default (including, without
limitation, any other default of the Borrowers' obligations under Section 7.7 of
the Loan Agreement), which may have existed on or prior to the date hereof or
which may hereafter arise. Further, the granting of this waiver shall not be
construed as a continuing waiver or waiver of any other Event of Default under
the Loan Agreement, or any other documents executed in connection therewith.

III. Certain Representations.  As a material inducement to the Bank to enter
     -----------------------
into this Amendment, each of the Borrowers hereby represents and warrants to the
Bank (which representations and warranties shall survive the delivery of this
Amendment), after giving effect to this Amendment, as follows:

     A.  The execution and delivery of this Amendment has been duly authorized
by all requisite corporate action on the part of each Borrower.

     B.  The representations and warranties contained in Section 4 of the Loan
Agreement, as amended by this Amendment are true and correct in all material
respects on and as of the date of this Amendment as though made at and as of
such date (except to the extent that such representations and warranties
expressly relate to an earlier date or except to the extent variations therefrom
have been permitted under the terms of the Loan Agreement or otherwise in
writing by the Lender).  No material adverse change has occurred in the assets,
liabilities, financial condition, business or prospects of any Borrower from
that disclosed in the financial statements most recently furnished to the Bank.
No Event of Default has occurred and is continuing.

     C.  The Borrowers are not required to obtain any consent, approval or
authorization from, or to file any declaration or statement with, any
governmental instrumentality or other agency or any other person or entity in
connection with this Amendment.

     D.  The execution and delivery of this Amendment and performance by each
Borrower of its respective obligations hereunder have been duly authorized by
all requisite corporate action and will not violate any provision of law, any
order, judgment or decree of any court or other agency of government, the
corporate charter and/or by-laws of each Borrower, or any indenture, agreement
or other instrument to which any Borrower is a party, or by which any Borrower
is bound.

     E.  This Amendment and the Note constitutes the legal, valid and binding
obligation of each Borrower, enforceable against each of them in accordance with
their respective terms, subject to bankruptcy, insolvency, reorganization,
moratorium and similar laws affecting the rights and remedies of creditors
generally or the application of principles of equity, whether in any action at
law or proceeding in equity, and subject to the availability of the remedy of
specific performance or of any other equitable remedy or relief to enforce any
right thereunder.

IV.  Conditions.  The willingness of the Lender to agree to the foregoing is
     ----------
subject to the following conditions:

     A.  Each Borrower shall have executed and delivered to Lender (or shall
have caused to be executed and delivered to Lender) the following:

         2.  The Note in the form of the new Exhibit 2.1 to the Loan Agreement

and Term Note dated February 20, 1996).

         3.  True and complete copies of all required stockholders' and
directors' consents and/or resolutions, authorizing the execution and delivery
of this Amendment and such other documents as may be necessary, certified by a
duly authorized officer of the appropriate Borrowers; and

                                      -3-

         4.  Such other supporting documents and certificates as the Lender or
its counsel may reasonably request.

and disbursements of the Lender's counsel;

     C.  All legal matters relating to this Amendment shall be satisfactory to
the Lender and its counsel.

V.   Exhibits.  Exhibit 2.1 to the Loan Agreement is deleted and the attached
     --------   -----------
Exhibit 2.1 is substituted therefor.
- - -----------

VI.  Effect of Amendment.  This Amendment constitutes an amendment to and
     -------------------
modification of the Loan Agreement and each of the Loan Documents.  Each
reference in the Loan Agreement and the other Security Documents to the "Loan
Agreement", "this Agreement", "hereunder", "hereof" or words of like import
referring to the Loan Agreement shall mean and be a reference to the Loan
Agreement, as amended by this Amendment.

VII. Miscellaneous.
     -------------

     A.  After the execution of this Amendment, the Lender, with the cooperation
of the Borrowers and at the Borrowers' expense, will promptly take all actions
necessary to cause the release of all liens of the Lender on the Borrowers'
assets and properties.

     B.  As provided in the Loan Agreement, the Borrowers jointly and severally
agree to reimburse the Lender upon demand for all reasonable out-of-pocket costs
and expenses of Lender, including all reasonable fees and disbursements of
counsel to the Bank incurred in connection with the preparation of this
Amendment, any releases, UCC-3 Termination Statements and any other agreements,
instruments and documents executed pursuant hereto.

     B.  This Amendment shall be governed by and construed in accordance with
the laws of the Commonwealth of Massachusetts.

     C.  This Amendment may be executed by the parties hereto in several
counterparts hereof and by the different parties hereto on separate counterparts
hereof, all of which counterparts shall together constitute one and the same
agreement.

     D.  The obligations of the Borrowers under this Amendment shall be joint
and several in nature.

                                      -4-

     IN WITNESS WHEREOF, the Lender and the Original Borrowers have caused this
Amendment to be duly executed as a sealed instrument by their duly authorized
representatives, all as of the day and year first above written.

Charges"). The debit balance of the Revolving Loan Account prior to the

Conversion Date shall reflect the amount of the Borrowers' Obligations to the
Lender from time to time in respect of Revolving Loans and other Bank Charges
hereunder. At least once each month the Lender may render a statement of account
showing as of its date the debit balance(s) of the Loan Account which, unless
within thirty (30) days of such date notice to the contrary is received by the
Lender from the Borrowers, shall be considered correct and accepted by the

hereto, provided that if such written confirmation differs in any material
        --------
respect from the action taken from the Lender, the records of the Lender shall
control absent manifest error.

      (b)   Whenever the Borrowers desire to obtain or continue a Money Market
Loan hereunder or convert an outstanding Base Rate Loan or LIBOR Loan to a Money
Market Loan, the Borrowers shall notify the Lender (which notice shall be

definition of Interest Period and Section 2.4). Each Notice of Borrowing or
Conversion relating to such a Money Market Loan shall be immediately followed by
a written confirmation thereof by the Borrowers in substantially the form of
Exhibit 2.2 hereto, provided that if such written confirmation differs in any
- - -----------         --------
material respect from the action taken from the Lender, the records of the
Lender shall control absent manifest error. With respect to each such Notice of
Borrowing or Conversion, the Lender shall, no later than 3:00 p.m. (Boston Time)
on the date of the requested Loan, notify the Borrowers of the Money Market Rate
available for the Interest Period and the amount of the Loan requested, or if,
the Lender is unable to quote a Money Market Rate in response to the Borrowers'
request, the Borrowers shall have until 3:00 p.m. (Boston Time) on the date it
receives the quoted Money Market Rate to accept the quoted Money Market Rate
which acceptance may be oral or in writing. If the Borrowers accept the rate
and, subject to the terms and conditions hereof, the Lender shall make the Money
Market Loan on the effective date specified therefor by crediting the amount of
such Loan to the Revolving Loan Account. If the Borrowers do not accept the
quoted Money Market Rate or if the Lender is unable to offer the Money Market

the Borrowers may request that the Loan be a Base Rate Loan.

      2.3   Commitment Fee.  (a) The Borrowers shall pay to the Lender a

      (b)   The Borrowers shall pay to the Lender any and all other reasonable
charges customarily made by the Lender against borrowers.

      2.4   Certain Interest Periods.  (a) If the Lender does not receive a

Notice of Borrowing or Conversion for an outstanding Fixed Rate Loan or a notice
of election of duration of an Interest Period for a Fixed Rate Loan pursuant to
Section 2.2, above, within the applicable time limit specified therein, or if,
when such notice must be given, a Default exists, the Borrowers shall be deemed
to have elected to convert such Fixed Rate Loan into a Base Rate Loan on the
last day of the then current Interest Period with respect thereto.

                                      -5-
<PAGE>
 
      (b)   Notwithstanding the foregoing, the Borrowers may not select an
Interest Period that would end, but for the provisions of the definition of
Interest Period, after the Conversion Date.

      2.5   Interest Rates and Payment of Interest.  (a) Each Base Rate Loan
            --------------------------------------
shall bear interest on the outstanding principal amount thereof at a rate per
annum equal to the Base Rate, which rate shall change contemporaneously with any
change in the Base Rate. Such interest shall be payable on the last day of each
month and when such Loan is due (whether at maturity, by reason of acceleration
or otherwise).

      (b)   Each LIBOR Loan shall bear interest on the outstanding principal
amount thereof, for each Interest Period applicable thereto, at a rate per annum
equal to the LIBOR Rate at the inception of such Interest Period plus one and
                                                                 ----
one-half percent (1.5%). Such interest shall be payable for such Interest Period
on the last Business Day of each month after the commencement date of the
Interest Period for such LIBOR Loan.

      (c)   Each Money Market Loan shall bear interest on the outstanding
principal amount thereof, for each Interest Period applicable thereto, at a rate
per annum equal to the quoted Money Market Rate for the amount and the Interest
Period requested plus one and one-half percent (1.5%). Such interest shall be
                 ----
payable for such Interest Period on the last Business Day of each month after
the commencement date of the Interest Period for such Money Market Loan.

      (d)   Overdue principal (whether at maturity, by reason of acceleration or
otherwise) and, to the extent permitted by applicable law, overdue interest and
fees or any other amounts payable hereunder (including without limitation
overadvances) due to the Borrowers' failure to pay the same in full shall bear
interest from and including the due date thereof until paid, at a rate per annum
equal to 4% above the rate which then applies to the Note, which interest shall
be compounded daily and payable on demand.

      (e)   If a payment of principal or interest hereunder is not made, due to
the Borrowers' failure to pay the same in full on its due date, the Borrowers
will also pay on demand a late payment charge equal to 5% of the amount of such
payment. Nothing provided herein shall affect the Lender's right to exercise any
of its rights or remedies, including those provided in Section 8.2, arising upon
the occurrence of an Event of Default.

      2.6   Indemnification.  The Borrowers shall pay to the Lender, upon the
            ---------------
request of the Lender, such amount or amounts as shall compensate the Lender for
any loss (including, in the case of Fixed Rate Loans, loss of profit), cost or
expense incurred by the Lender (as reasonably determined by the Lender) as a
result of: (a) any payment or prepayment (whether voluntarily or after
acceleration and demand by the Lender pursuant to its rights hereunder) or
conversion of any Fixed Rate Loan held by the Lender on a date other than the
last day of the Interest Period for such Fixed Rate Loan; or (b) any failure by
the Borrowers to borrow, convert into or continue a Fixed Rate Loan on the date
for such borrowing specified in the relevant Notice of Borrowing or Conversion
or otherwise; such compensation to include, without limitation; an amount equal
to: (i) any loss or expense suffered by the Lender during the period from the
date of receipt of such early payment or prepayment or the date of such
conversion or failure to borrow, convert or 

                                      -6-
<PAGE>
 
continue to the last day of such Interest Period, if the rate of interest
obtainable by the Lender upon the redeployment of an amount of funds equal to
the Fixed Rate Loans so paid, prepaid or converted or as to which such failure
to borrow, convert or continue applies is less than the rate of interest
applicable to such Loans for such Interest Period and (ii) any loss or expense
suffered by the Lender in liquidating LIBOR or Money Market deposits, as the
case may be, prior to maturity which the Lender is unable to redeploy and which
correspond to the Fixed Rate Loans so paid, prepaid or converted or as to which
such failure to borrow, convert or continue applies. The determination by the
Lender of the amount of any such loss or expense, then set forth in a written
notice to the Borrowers, containing the Lender's calculation thereof in
reasonable detail, shall be presumed correct in the absence of manifest error.

      2.7   Capital Requirements.  If, after the date hereof, the Lender
            --------------------
determines that (i) the adoption of or change in any law, rule, regulation or
guideline regarding capital requirements for lenders or bank holding companies,
or any change in the interpretation or application thereof by any governmental
authority charged with the administration thereof, or (ii) compliance by the
Lender or its parent bank holding company with any guideline, request or
directive of any such entity regarding capital adequacy (whether or not having
the force of law), has the effect of reducing the return on the Lender's or such
holding company's capital as a consequence of the Lender's commitment to make
Loans hereunder to a level below that which the Lender or such holding company,
but for such adoption, change or compliance, could have achieved (taking into
consideration the Lender's or such holding company's then existing policies with
respect to capital adequacy and assuming the full utilization of such entity's
capital) by any amount deemed by the Lender to be material, then the Lender
shall notify the Borrowers thereof. The Borrowers agree to pay to the Lender the
amount of such reduction as and when such reduction is determined, upon
presentation by the Lender of a statement in the amount and setting forth the
Lender's calculation thereof, which statement shall be deemed true and correct
absent manifest error. In determining such amount, the Lender may use any
reasonable averaging and attribution methods.

      2.8   Payments and Prepayments.  (a) (i) Prior to the Conversion Date, the
            ------------------------
Borrowers may prepay the Revolving Loans, in whole or in part, as follows:

                   (A)  Base Rate Loans may be prepaid at any time without
premium or penalty, including, without limitation, pursuant to Section 2.9
hereof. Amounts so paid may, prior to the Conversion Date and within the limits
of the Commitment, be borrowed and reborrowed as provided in Section 2.1.

                   (B)  LIBOR Loans may be prepaid (subject to payment of
amounts due in accordance with Section 2.6 in respect of any LIBOR Loans so
prepaid) on not less than two (2) Business Days prior written notice to the
Lender;

                   (C)  Money Market Loans may be prepaid (subject to payment of
amounts due in accordance with Section 2.6 in respect of any Money Market Loans
so prepaid) on not less than one (1) Business Day prior written notice to the
Lender.

                                      -7-
<PAGE>
 
            (ii) If at any time the aggregate principal balance of the
outstanding Revolving Loans exceeds the Commitment, the Borrowers shall promptly
pay cash to the Lender in an amount as shall be necessary to eliminate such
excess.

      (b)   After the Conversion Date, the Borrowers shall repay the principal
amount outstanding under the Note on the Conversion Date (the "Term Loan
                                                               ---------

      (c)   The Lender may, and the Borrowers hereby authorize the Lender to,
debit the amount of any payment provided for in this Agreement or the Notes to
the Revolving Loan Account.

      2.9   Use of Proceeds; Loans to Subsidiaries.  (a) The proceeds of the
            --------------------------------------
Revolving Loans shall be used (i) for working capital purposes of the Borrowers,
including without limitation, Capital Expenditures, including costs and expenses
incurred in connection with start-up businesses in the New Markets; (ii) for
Permitted Investments, and (iii) to make Equity Distributions in respect of the
Parent's capital stock.

      (b)   The Parent may reloan the proceeds of the Revolving Loans to one or
more of the Subsidiaries pursuant to Intercompany Loans, provided that each such
Intercompany Loan to any Subsidiary (i) is evidenced by such Subsidiary's
Intercompany Note bearing interest at a rate not less than the rate applicable
to the Note, and (ii) is secured by a perfected security interest in all
presently owned and hereafter acquired tangible and intangible personal property
and fixtures of such Subsidiary, subject only to Permitted Encumbrances.

      (c)   The Parent hereby acknowledges and agrees with the Lender and each
of the Subsidiaries that (i) all Intercompany Loans are and shall be in all
respects subordinate to the Obligations of the Subsidiaries to the Lender under
the Note and otherwise, such subordination 

                                      -8-
<PAGE>
 
to be effective only to the extent that such Obligations are valid, binding and
enforceable; (ii) from and during the existence of any Default, unless otherwise
consented to by the Lender, all payments owed by any Subsidiary in respect of
the Intercompany Loans shall be made directly to the Lender to retire amounts
owed on the Note and all other Obligations; and (iii) if any payments are made
by or on behalf of any Subsidiary to the Lender to be applied by the Lender to
repay the Revolving Loans or any other Obligations, including interest, fees or
other charges thereon, then the balance of the principal, interest, fees and
other charges outstanding in respect of the Intercompany Loans shall be reduced
by the amount of all such payments.

      2.10  Requirements of Law.  (a) In the event that any Regulatory Change
            -------------------
shall:

            (i)    change the basis of taxation of the amounts payable to the
Lender in respect of any Fixed Rate Loans (other than taxes imposed on the
overall net income of the Lender);

            (ii)   impose or modify any reserve, compulsory loan assessment,
special deposit or similar requirement relating to any extensions of credit or
other assets of, or any deposits with or other liabilities of, any office of the
Lender in respect of any Fixed Rate Loans (including any of such Loans or any
deposits referred to in the definitions of "LIBOR Base Rate" or "Money Market
                                            ---------------      ------------
Rate" in Section 1); or
- - ----

            (iii)  impose any other conditions affecting Fixed Rate Loans;

      and the result of any of the foregoing shall be to increase the Lender's
costs of making or maintaining any Fixed Rate Loans, or to reduce any amount
receivable by the Lender hereunder in respect of any of its Fixed Rate Loans, in
each case only to the extent that such additional amounts are not included in
the LIBOR Base Rate or the Money Market Rate, as the case may be, applicable to
such Loans, then the Borrowers and Lender shall thereafter attempt to negotiate
in good faith, within thirty (30) days of the day on which the Borrowers receive
the notice referred to in Section 2.10(b), an adjustment payable hereunder that
will adequately compensate the Lender in light of these circumstances. If the
Borrowers and the Lender are unable to agree to such adjustment within thirty
(30) days of the date on which the Borrowers receive such notice, then
commencing as of the date of such notice applicable to such Fixed Rate Loans,
the Borrowers shall pay on demand to the Lender and from time to time as
specified by the Lender, such additional amounts as shall be sufficient to
compensate the Lender for such increased cost or reduced amount receivable. Such
amounts may include amounts that arise by reason of such a Regulatory Change for
not more than thirty (30) days before receipt by the Borrowers of such notice.

      (b)   If the Lender becomes entitled to claim any additional amounts
pursuant to this Section, it shall promptly notify the Borrowers of the event by
reason of which it has become so entitled. A certificate setting forth in
reasonable detail the computation of any additional amounts payable pursuant to
this Section submitted by the Lender to the Borrowers shall be delivered to the
Borrowers promptly after the initial incurrence of such additional amounts and
shall be conclusive in the absence of manifest error. The covenants contained in
this Section shall survive for six (6) months following the termination of this
Agreement and the payment of 

                                      -9-
<PAGE>
 
the outstanding Note. No failure on the part of the Lender to demand
compensation under paragraph (a) above on any one occasion shall constitute a
waiver of its rights to demand compensation on any other occasion. The
protection of this Section shall be available to the Lender regardless of any
possible contention of the invalidity or inapplicability of any law, regulation
or other condition which shall give rise to any demand by the Lender for
compensation thereunder.

      2.11. Limitations on Fixed Rate Loans; Illegality. (a) Anything herein to
            -------------------------------------------
the contrary notwithstanding, if, on or prior to the determination of an
interest rate for any Fixed Rate Loans for any applicable Interest Period, the
Lender shall determine (which determination shall be conclusive absent manifest
error) that:

            (i)  by reason of any event affecting United States money markets or
the London interbank market, quotations or interest rates for the relevant
deposits are not being provided in the relevant amounts or for the relevant
maturities for purposes of determining the rate of interest for such Loans under
this Agreement; or

            (ii) the rates of interest referred to in the definitions of "LIBOR
                                                                          -----
Base Rate" or "Money Market Rate" in Section 1, on the basis of which the rate
- - ---------
of interest on any Fixed Rate Loan for such period is determined, do not
accurately reflect the cost to the Lender of making or maintaining such Fixed
Rate Loans for such period;

      then the Lender shall give the Borrowers prompt notice thereof (and shall
thereafter give the Borrowers prompt notice of the cessation, if any, of such
condition), and so long as such condition remains in effect, the Lender shall be
under no obligation to make Fixed Rate Loans or to convert Base Rate Loans into
Fixed Rate Loans and the Borrower shall, on the last day(s) of the then current
Interest Period(s) for any outstanding Fixed Rate Loans, either prepay such
Fixed Rate Loans, or convert such Fixed Rate Loans into Base Rate Loans, in
either case, in accordance with the provisions of the Loan Agreement.

      (b)   Notwithstanding any other provision herein, if any Regulatory Change
shall make it unlawful for the Lender to make or maintain Fixed Rate Loans as
contemplated by this Agreement, (i) the Lender's commitment hereunder to make
Fixed Rate Loans, continue Fixed Rate Loans as such and convert Base Rate Loans
to Fixed Rate Loans shall thereupon terminate and (ii) the Lender's Loans then
outstanding as Fixed Rate Loans, if any, shall be converted automatically to
Base Rate Loans on the respective last days of the then current Interest Periods
with respect to such Loans or within such earlier period as required by law. If
any such conversion of a Fixed Rate Loan occurs on a day which is not the last
day of the then current Interest Period with respect thereto, the Borrowers
shall pay to the Lender such amounts, if any, as may be required pursuant to
Section 2.6.

satisfactory to the Lender), of the value of the Borrowing Base as of the end of

II.   Waivers.  The Lender hereby agrees to waive the following:
      -------

      A.   The Event of Default which occurred as of February 3, 1997 because
the Parent formed two new subsidiaries, LoJack of Pennsylvania, Inc. and LoJack
FSC, LTD., without first obtaining the consent of the Lender in accordance with
Section 7.7 of the Loan Agreement.

      B.   The foregoing waiver is limited to its express terms and shall not
be deemed to be a waiver of any other Event of Default (including, without
limitation, any other default of the Borrowers' obligations under Section 7.7 of
the Loan Agreement), which may have existed on or prior to the date hereof or
which may hereafter arise. Further, the granting of this waiver shall not be
construed as a continuing waiver or waiver of any other Event of Default under
the Loan Agreement, or any other documents executed in connection therewith.

III.  Certain Representations.  As a material inducement to the Lender to enter
      -----------------------
into this Amendment, each of the Borrowers hereby represents and warrants to the

Amendment), after giving effect to this Amendment, as follows:

      A.   The execution and delivery of this Amendment and performance by each
Borrower of its respective obligations hereunder have been duly authorized by
all requisite corporate action and will not violate any provision of law, any
order, judgment or decree of any court or other agency of government, the

or other instrument to which any Borrower is a party, or by which any Borrower
is bound.

      B.   The representations and warranties contained in Section 4 of the
Loan Agreement are true and correct in all material respects on and as of the

<PAGE>
 
made at and as of such date (except to the extent that such representations and
warranties expressly relate to an earlier date or except to the extent
variations therefrom have been permitted under the terms of the Loan Agreement
or otherwise in writing by the Lender). No material adverse change has occurred
in the assets, liabilities, financial condition, business or prospects of any
Borrowers from that disclosed in the financial statements most recently
furnished to the Lender. No Event of Default has occurred and is continuing.

      C.   The Borrowers are not required to obtain any consent, approval or
authorization from, or to file any declaration or statement with, any

obligation of each Borrower, enforceable against each of them in accordance with

            Updates, revisions, and new releases to the Licensed Software
            Programs will be made available to LICENSEE at no cost, provided
            that LICENSEE is responsible, at its cost, of adapting such
            improvements to its own System.

     1.4    In consideration of the payment by LICENSEE of the amount set forth
            in Section 2.1, LICENSOR hereby grants to LICENSEE the exclusive
            license to use, solely in the Territory for the purpose described in
            Sections l.2 and l.7, the rights granted under this Agreement in
            connection with the operation of the System, during the term of this
            Agreement, including but not limited to any Patent Rights that may
            be granted in said Territory.

     1.5    During the term of this Agreement and within the Territory, LICENSOR
            grants to LICENSEE, subject to all terms and conditions set forth in
            this Agreement, the exclusive license to use the Trademarks solely
            and exclusively in connection with the sale of Products in the
            Territory and for no other use or purpose. LICENSEE recognizes and
            acknowledges that the LICENSEE is the sole and exclusive LICENSEE of
            the Trademarks and agrees not to register any of the Trademarks in
            its own name or that of any other firm, person, or corporation and

            shall continue for a term of ten (10) years, with automatic renewals
            for successive five (5) year periods thereafter subject to earlier
            termination as provided in Article 14 of this Agreement, and other
            provisions of this Agreement. Notwithstanding the foregoing, the
            automatic term renewal provided above shall not take effect if
            LICENSEE shall be in default beyond grace of its obligations
            hereunder, or in the event of the occurrence of any other event of
            default under Article 14 of this Agreement.

     1.7    The rights herein granted are limited to sales of Products for
            ultimate use in motor vehicles located in the Territory, which
            includes trucks. LICENSEE agrees not to use the Licensed Rights,
            System, or technology utilized therein for any other or additional
            applications without the written approval of LICENSOR in each
            instance, which approval shall be at LICENSOR's sole discretion and
            may require payment of an additional fee. In no event shall LICENSEE
            be allowed to use or sell Products for any purpose outside the
            Territory, and LICENSEE specifically consents to this restriction
            and limitation.

            party that any activities of LICENSEE pursuant to this Agreement

            such event, LICENSOR shall, at its sole expense, without cost to
            LICENSEE:

                 (i)  defend against such claim and indemnify and hold harmless
            LICENSEE against all damages, liabilities, costs and expenses that
            may be suffered or incurred by LICENSEE in connection with such
            claim and any legal proceedings in respect thereof ("Defensive
            Litigation"), provided that LICENSEE shall have given notice as
            provided above of any such claim forthwith upon becoming aware of it
            and further gives LICENSOR the sole conduct of the defense of
            litigation and does not at any time admit liability or otherwise
            attempt to settle or

                                      -6-

            compromise the said claim or any legal action or proceedings in
            respect thereof except upon the express written instructions of
            LICENSOR, and acts in accordance with the reasonable instructions of
            LICENSOR as notified to LICENSEE and gives LICENSOR such assistance
            as it shall reasonably require and instruct LICENSEE in writing to
            provide in connection with the conduct of the Defensive Litigation
            including, without prejudice to the generality of the foregoing, the
            filing of all pleadings and other court process and the provision of
            all relevant documents and the right to use LICENSEE's name or to
            join LICENSEE as a party to the proceedings, or

                 (ii)   procure the right for LICENSEE to continue exercising
            the Licensed Rights granted hereunder, or LICENSOR shall make such
            alterations, modifications and adjustments to the Licensed Rights as
            may be necessary to make the exercise thereof non-infringing,
            without incurring any material diminution of the performance or
            function of the System, or replace all or any part of the Licensed
            Rights with non-infringing substitutes provided that such
            substitutes do not entail a material diminution in performance; or

                 (iii)  in the event that LICENSOR, despite the use of
            reasonable efforts, cannot reasonably accomplish either (i) or (ii)
            above, at reasonable expense, then LICENSOR shall refund a
            proportionate part of LICENSEE fee provided in Section 2.1,
            proportionate to the degree to which LICENSEE is prohibited from
            exercising its rights in this Agreement.

            (b)  In the event of any infringement or claimed infringement of the
            Licensed Rights by a third party, LICENSEE shall promptly notify
            LICENSOR of said infringement or claimed infringement to the extent
            such infringement would materially and adversely affect the value of
            the Licensed Rights to the LICENSEE. In such a case, LICENSOR shall
            promptly notify LICENSEE what action, if any, LICENSOR in its sole
            discretion elects to take in respect of such matter. LICENSOR shall
            have sole conduct of any action it elects to take in such matter
            ("Offensive Litigation") and either; LICENSOR shall pay all costs in
            connection with such Offensive Litigation and shall be entitled to
            all damages and other sums which may be paid or awarded as a result
            thereof; or if within ten (10) business days after its receipt of
            such notice LICENSEE agrees to share equally the costs of such
            Offensive

                                      -7-

            Litigation, the costs of any such Offensive Litigation shall be
            borne, and all damages and other sums which may be paid or awarded
            as a result thereof shall be shared equally by, LICENSOR and
            LICENSEE as they relate to the Territory.

            (c) In the event that LICENSOR fails to accept the conduct of any
            Offensive Litigation within a reasonable period after notice from
            LICENSEE requesting LICENSOR to do so, LICENSEE shall be entitled at
            its cost and expense to take all such actions as it deems necessary
            or desirable in connection with such infringement or claimed
            infringement to the extent such infringement would materially and
            adversely affect the value of Licensed Rights to the LICENSEE, and
            LICENSEE shall be entitled to all damages and other sums which may
            be recovered by or awarded to it as a result thereof.

            (d) The LICENSOR shall reimburse LICENSEE its reasonable costs and
            expenses incurred in complying with the provisions of section 1.8
            (a) above. (Assistance for Defensive Litigation). LICENSOR shall
            have no liability or obligation to LICENSEE in respect of any
            Defensive Litigation or Offensive Litigation if the same results
            from any breach of LICENSEE's obligations under this Agreement.

                  (960)  Vehicle Location Units (VLUs)
      
            The Initial Purchase Order and any subsequent purchase orders are
            referred to in the Agreement as "Purchase Orders".

            The delivery of the VAC, VAT's and VTC's ordered under the Initial
            Purchase Order shall be made within four (4) months following the
            acceptance of the Initial Purchase Order. The delivery of the VLUs
            shall be made within six (6) months of the acceptance of the Initial
            Purchase Order. The actual quantity of VLUs ordered by Purchase
            Order by LICENSEE may be increased or decreased (in no case shall it
            be reduced below the minimum specified in Section 16) by twenty-five
            (25%) percent by giving ninety (90) days written notice to LICENSOR,
            prior to scheduled shipments. For purposes of this Agreement
            "delivery date" shall mean the date on which LICENSOR delivers

            Subsequent Purchase Orders for the Products shall be authorized in
            writing by LICENSEE and shall specify requested delivery dates, but
            in no instance should such Purchase Orders specify delivery dates

            the LICENSOR's fault or negligence. LICENSOR shall not be liable for
            shipping over routes or by means of transportation not specified by
            LICENSEE. If LICENSEE does not specify shipping routes, LICENSOR
            shall select routes and shall have no liability to LICENSEE by
            reason of such selection.

     2.4    All Products are priced in United States dollars and payment,
            therefore, shall be made by LICENSEE in United States dollars. Upon
            placement of a Purchase Order for the Products, LICENSEE shall cause
            to be issued by a bank satisfactory to LICENSOR, an Irrevocable
            Letter of Credit in favor of LICENSOR, valid for the greater of six
            (6) months or a period covering the shipping schedule of the
            Products specified in the Purchase Order. Such letter of credit
            shall be in an amount equal to the full amount of the Purchase Order
            and provide for partial shipments, and payable upon presentation of
            an Airway Bill or Bill of Lading, LICENSOR's Commercial Invoice,
            Packing List, Certificate of Origin, and any other documents
            required. In the case of the initial Purchase Order the letter of
            credit shall be in the amount of no less than the total of items on
            Attachment V. Delivery of equipment and costs shall be determined
            and made a part of this Agreement as Attachment V.

     2.5    LICENSOR hereby guarantees that the prices payable by LICENSEE for
            the VTCs and VLUs will not be increased for one (1) year from the
            Effective Date of this Agreement. Thereafter, LICENSOR shall provide
            the VTCs and VLUs at a price no less favorable than those it offers
            other Licensee who purchase similar annual volumes.

     2.6    All fees and other amounts payable by LICENSEE to LICENSOR under
            this Agreement are exclusive of any Korean Value Added Tax or other
            Korean Tax, or Duty (except as provided in Section 2.8).

     2.7    All amounts payable either party to the other party under this
            Agreement which are not paid when due shall bear and be payable with
            interest at 1% (one percent) over the Prime Rate as reported by the
            Bank of Boston, determined at such due date, and calculated from
            such due date to the date of actual payment (whether after judgment
            or before).

            by LICENSEE to LICENSOR under this Agreement (Section 2.1 for
            Payment Shcedule less any applicable tax deduction.) shall be tax
            deductible according to Convention between the Government of Korea
            and USA to avoid double taxation and LICENSEE shall deduct or
            withhold the taxes, charges and duties and pay over to the relevant
            authority the full amount with the balance being paid to LICENSOR.
            LICENSEE shall promptly forward to LICENSOR a certified copy of the
            original official receipt issued by each appropriate Taxing
            authority or other agency, evidencing payment in full. LICENSEE

            requested by LICENSOR to obtain a credit or deduction in the United
            States of such taxes so deducted or withheld.

     2.9    The parties agree to cooperate in all such respects as may be
            reasonably necessary or desirable in order to obtain such relief
            from double taxation as may be available under the double taxation
            treaty between the Governments of the Territory and the United
            States.

     4.1    Recognizing that LICENSOR has developed a unique System, and in

            Proprietary Information of the LICENSOR and assure uniform product
            quality and specification compliance and control, LICENSEE shall
            purchase from LICENSOR all Products which it uses or sells, except
            standard off-the-shelf items ordinarily purchased by LICENSOR from
            third parties. In addition, the LICENSEE will not sell any products
            which are in competition with the Products. LICENSEE agrees to offer
            in connection with the sale of VLUs, only the standard warranty from
            time-to-time given by LICENSOR to its retail customers, except as
            LICENSOR may otherwise in writing approve.

     4.2    LICENSEE assures that installation of VLUs shall be in compliance
            and conformity with all procedures and standards reasonably

        6.1    LICENSEE acknowledges that certain permits, approvals,
               authorizations and licenses necessary to operate the System in
               the Territory (herein collectively called the "Required Permits")
               may be required by governmental or other authorities prior to
               operation of the System in the Territory and for the continued
               operation thereof. LICENSEE hereby warrants to LICENSOR that it
               has undertaken sole responsibility at its sole expense to procure
               and prior to commencement of operations of the System in the
               Territory shall have procured all such Required Permits necessary
               to commence the operation of the System. LICENSEE specifically
               represents and warrants that it shall make information regarding
               all such Required Permits available to LICENSOR from time-to-time
               within thirty (30) days after receipt of LICENSOR's written
               request, therefore, and that LICENSEE shall make all payments,
               submit all filings and applications, and do all things necessary
               to keep all such Required Permits at all times current and in
               full force and effect at its sole expense. LICENSEE further
               warrants that it shall procure any and all other permits,
               permissions, licenses and approvals (from all governmental and
               other authorities and others), hereafter required or otherwise
               necessary for the operation or use of the System in the Territory
               (all of which shall be referred to as the "Required Permits"
               hereunder). It is specifically agreed that LICENSOR shall have no
               obligations or liability to LICENSEE for any loss, cost or damage
               arising from LICENSEE's failure to procure or to maintain any
               Required Permits.

        6.2    LICENSEE at all times shall comply with all limitations
               regulations, rules, guidelines and requirements of any
               governmental authorities ("Regulatory Body") having jurisdiction
               in the Territory granting any of the Required Permits, including,
               without limitation, those issued by authorities having
               jurisdiction over radio transmissions licenses, permits or
               approvals, or otherwise and in any way regulating or affecting
               the System, or its operation or use in the Territory. LICENSOR
               will provide to LICENSEE, subject to the confidentiality
               provisions in Section 9 hereof, at no cost to LICENSEE, all
               documents, information or data in the LICENSOR's control or
               possession which LICENSEE reasonably determines to be necessary
               for LICENSEE to obtain or maintain any Required Permit or to
               comply with any requirement of any Regulatory Body, and LICENSOR
               will provide same with all due diligence and dispatch upon
               receipt of a written request for same from LICENSEE.

        6.3    LICENSOR and LICENSEE, upon request of the other, will cooperate
               with the other with respect to the filing and/or recording, if
               applicable, of this Agreement (and any amendments thereto from
               time-to-time in effect), or notice thereof, as applicable, with
               all governmental authorities and other Regulatory Bodies in the
               Territory necessary for the effectuation and/or enforcement
               thereof. LICENSEE shall deliver an opinion of counsel that no
               filing of this or any other agreement between LICENSOR and
               LICENSEE are required and that such agreements are enforceable in
               Korea.

        6.4    LICENSEE hereby grants and assigns to LICENSOR, to the extent
               permitted by law, and assigns to the LICENSOR all of its rights,
               title, and interest in and to the Required Permits, which
               assignment shall take effect and become operable only upon the
               expiration of the term of this Agreement, or upon the earlier
               termination of this Agreement pursuant to Article 14, or as
               otherwise provided in this Agreement, provided that LICENSOR
               shall reimburse LICENSEE all of its reasonable costs and expenses
               (to be negotiated) incurred to obtain and maintain the Required
               Permits.

8.      INDEMNIFICATION
        ---------------

        8.1    The LICENSOR agrees to indemnify and hold harmless LICENSEE and,
               if applicable, each of LICENSEE's officers, directors, agents,
               employees and controlling persons against any and all loss,
               liability, claim, damage and expense arising solely from a defect
               in the design or manufacture of Products purchased by LICENSEE
               from LICENSOR except that this indemnification shall not extend
               to any loss, liability, claim, damage or expense attributed
               solely to those matters for which LICENSEE has indemnified
               LICENSOR pursuant to section 8.2. below.

        8.2    LICENSEE agrees to indemnify and hold harmless LICENSOR and each
               of LICENSOR's officers, directors, agents, employees and
               controlling persons against any and all loss, liability, claim,
               damage and expense, including attorney's fees, arising solely in
               connection with either (a) LICENSEE's establishment and operation
               of the System, or (b) the sale and installation by LICENSEE of
               the Products, or (c) the conduct of business by LICENSEE pursuant
               to, or as contemplated by, this Agreement, except that this
               indemnification shall not extend to any loss, liability, claim,
               damage or expense attributable solely to those matters for which
               LICENSOR has indemnified LICENSEE pursuant to Section 8.1 above.

        8.3    Promptly after receipt by an indemnified party pursuant to
               Section 8.1 above or Section 8.2 above of actual notice of the
               commencement of any action giving rise to indemnification rights
               under Section 8.1 above or Section 8.2 above, such indemnified
               party shall, if a claim in respect thereof is to be made against
               the indemnifying party under the applicable section, notify the
               indemnifying party in writing of the commencement thereof. The
               failure to so notify the indemnifying party shall relieve it from
               any liability which it may have to any indemnified party under
               such section, but shall not relieve it from any liability which
               it may

                                     -16-
<PAGE>
 
         have to any indemnified party otherwise than under such section.  Upon
         receipt of notice from the indemnified party as aforesaid , the
         indemnifying party shall be entitled to participate in, and, to the
         extent that it shall wish, to assume the defense of, the action, with
         counsel selected and paid for by the indemnifying party but reasonably
         satisfactory to the indemnified party.

         After the indemnified party shall have received notice from the agreed
         upon counsel that the defense has been assumed, the indemnifying party
         shall not be responsible for any legal or other expense subsequently
         incurred by such indemnified party in connection with the defense
         thereof, other than reasonable costs of investigation, unless incurred
         at the written request of the indemnifying party or the indemnifying
         party shall not have employed counsel to have charge of the defense of
         such action or in the opinion of counsel to the indemnified party, the
         indemnified party shall have reasonably concluded that there may be
         defenses available to it which are different from or additional to
         those available to the indemnifying party (in which case the
         indemnifying party shall not have the right  to assume the defense of
         such action on behalf of the indemnified party) in any of which events
         such legal or other expenses shall be borne by the indemnifying party.
         In no event shall the indemnifying party be liable for the fees and
         expenses of more than one counsel for all indemnified parties, in
         connection with any one action or separate but similar or related
         actions in the same jurisdiction arising out of the same general
         obligations or circumstances, unless in the opinion of counsel to the
         indemnified party, the indemnified party shall have reasonably
         concluded and advised by indemnifying party that there may be defenses
         available to it which are different from or additional to those
         available to other indemnified parties, in which case the indemnifying
         party shall be responsible for the fees and expenses of such additional
         counsel as is reasonably required.  The indemnifying party shall not be
         liable under the indemnity provisions set forth above for any amount
         paid in settlement of any claim unless such indemnifying party
         consented in writing to any such settlement.

          or to be disclosed by LICENSOR to LICENSEE or obtained by LICENSEE
          from LICENSOR pursuant to this Agreement) and all other information
          that LICENSOR designates as confidential and discloses to LICENSEE
          pursuant to this Agreement, to respect LICENSOR's proprietary rights
          in the Confidential Information, to use the Confidential Information

          further procure that all of its employees and all of such sub-
          contractors shall enter into a non-disclosure agreement substantially
          in the form set forth in Attachment IV.

10.  WARRANTY
     --------

     10.l LICENSOR shall provide LICENSEE with Quality Assurance Certificate for
          the Products and Inspection Standard for the Products. LICENSOR
          warrants to LICENSEE that the Products when purchased from LICENSOR,
          under normal use and service, will be free from defect in materials
          and workmanship. This warranty shall be in effect for a period of the
          greater of (i) l (one) year from the delivery date of VLUs, VACs, VATs
          and VTCs to LICENSEE or (ii) the period of the same warranty LICENSOR
          receives from its manufacturers from time-to-time. LICENSOR's
          liability for honoring the warranty claims is subject to LICENSEE
          making claims for defective Products within the applicable Warranty
          Period, and any claims not made within the Warranty Period shall be
          conclusively deemed waived and released.

    10.2  During the Warranty Period for respective Products, LICENSOR shall, at
          its option, replace or repair, at any authorized repair facility in
          the Territory designated by LICENSOR, any Products which LICENSOR
          determines to be defective. In the event that LICENSOR does not hold a
          sufficient number of stock of VLUs in the Far East for replacement and
          does not have an authorized repair facility in the Territory to meet
          the warranty claims, the LICENSOR shall deliver to LICENSEE without
          any cost to LICENSEE with each shipment of VLUs in accordance with the
          Purchase Order an additional quantity of VLUs equal to one percent
          (l%) of the quantity so ordered by LICENSEE (the "Warranty Replacement
          Stock"). LICENSEE shall maintain the Warranty Replacement Stock in its
          warehouse and shall use them for replacement of the defective units
          and make a monthly report to LICENSOR on the replacement occurring
          during each calendar month and remaining balance, along with number of
          defective units returned.

    10.3  The foregoing warranty does not apply to any Products which have been
          damaged as a result of force majeure, accident, shipping and handling,
          improper power supply, misuse, abuse, improper storage, improper
          maintenance, improper installation, improper operation, unauthorized
          modification, or which has been installed, serviced, modified or
          repaired by anyone other than a person designated in writing by the
          LICENSOR, as an authorized service representative.

    10.4  EXCEPT AS EXPRESSLY SET FORTH ABOVE, NO OTHER WARRANTIES ARE EXPRESSED
          OR IMPLIED, INCLUDING BUT NOT LIMITED TO ANY IMPLIED WARRANTIES OF
          MERCHANTABILITY OR FITNESS FOR A PARTICULAR PURPOSE, AND THE LICENSOR
          EXPRESSLY DISCLAIMS ALL WARRANTIES NOT STATED HEREIN. THE LICENSOR'S
          SOLE OBLIGATION FOR VALID WARRANTY CLAIMS AND LICENSEE'S SOLE REMEDY
          ON ACCOUNT OF WARRANTY CLAIMS SHALL BE FOR REPAIR OR REPLACEMENT AS
          PROVIDED ABOVE. UNDER NO CIRCUMSTANCES WILL THE LICENSOR BE LIABLE TO
          THE LICENSEE OR ANY OTHER PERSON FOR ANY DAMAGES OF ANY KIND
          WHATSOEVER, INCLUDING WITHOUT LIMITATION ANY INCIDENTAL OR
          CONSEQUENTIAL DAMAGES.

          promotions and advertising of Products in the Territory, and that no

          LICENSOR either (a) permits Products to be sold or distributed in the
          Territory by a party other than LICENSEE, or (b) permits a party other
          than LICENSEE to provide service in the Territory with respect to any
          Products distributed, sold, or sublicensed by LICENSEE, then in either
          event the LICENSOR or its designee (the "Purchaser") may purchase
          inventory and such other assets, in good and marketable condition, as
          agreed by both parties which are part of or relate to the System
          within the Territory, including, items such as:

                                     -22-
<PAGE>
 
          VTCs, the VACs, VATs, VLUs (the "Designated Assets"). The price which
          purchaser shall pay for such Assets shall be by mutual agreement
          between the LICENSOR and LICENSEE. The closing of the sale shall occur
          in Boston, Massachusetts. At such closing, the Purchaser shall pay in
          cash to LICENSEE the price set forth above for all of the Designated
          Assets and LICENSEE shall execute and deliver such agreements
          (including without limitation an Asset Purchase Agreement containing
          such reasonable representations and warranties and other terms and
          conditions as the Purchaser may require), instruments and other
          documents as are necessary to transfer to the Purchaser the Designated
          Assets which the Purchaser is acquiring, free and clear of all liens,
          encumbrances and restrictions (unless otherwise agreed to by the
          Purchaser).

     15.3 Immediately upon the expiration or earlier termination of this
          Agreement, LICENSEE shall cease and forever abstain from using the
          Trademarks and to deliver to LICENSOR all documents, instructions,
          display items, and the like bearing any of the Trademarks. To the
          extent that such items were originally purchased from LICENSOR, are in
          original packaging and can be used by LICENSOR, upon any such
          termination LICENSOR may buy from and pay LICENSEE a price for such
          items, and the price shall be mutually agreeable between the LICENSOR
          and LICENSEE.

    15.4  To the extent permitted under the laws of the Territory immediately
          upon the expiration or earlier termination of this Agreement, LICENSEE
          shall assign to LICENSOR, free and clear of all liens, encumbrances,
          and restrictions, permits to operate the System by any governmental
          authority or other regulatory bodies.

                             2 SYSTEM REQUIREMENTS
                             ---------------------

The following requirements pertain to the CarSearch System as a whole:

2.1 Compatibility with existing equipment/services
    ----------------------------------------------

The CarSearch System must be able to use and interface with if appropriate, the 
following existing equipment/services.

    .   The Public Switched Telephone Network (PSTN)

    .   Existing radio communications equipment on site.

    .   An operating frequency between 165-174 MHz, inclusive, for all 
        components.

    .   Existing computer equipment on site.


2.2 General system description
    --------------------------

The CarSearch System consists of one central computer (VAC) available for human 
interface, and one to eight remote devices (VAT) each of which is located at a 
radio transmitter site.  The VAC computer communicates with each VAT over a 
switched telephone line via 1200 baud Hayes-compatible modems.  No other means
                                                                -- -----
of communication is provided.  In addition to the VAC and VAT, Vehicle Location 
Units are installed into customer vehicles or which are activated by the 
transmission of the appropriate activation code.

2.3 Principal system function
    -------------------------

The principal function of the system is to conveniently support the following:

A user informs a central computer via a local user interface that an VLU with a 
specified activation and reply code is to be activated, or deactivated.  The 
central computer then informs the set of remote devices, each of which transmits
via radio a corresponding control signal(s) via its Mod/PTT connection.

2.4 Limitations
    -----------

Following are explicit limitations indicating what the system is not expected to
                                                                 ---
do.

2.4.1 Police Involvement
      ------------------

The CarSearch System has no involvement of any sort with law enforcement 
computer systems, or radio facilities.
<PAGE>
 
This means that CarSearch does not receive reports on stolen vehicles as a 
normal consequence of the theft being reported to police.  Rather, the owner of 
a stolen VLU equipped vehicle must take steps to report the theft to the 
CarSearch Operation Center.

This does not in any way preclude the participation of police vehicles which may
have VTC to track and recover stolen vehicles.  Police so equipped would need to
communicate directly with the CarSearch Operation Center to query reply codes 
and deactivated recovered VLU equipped vehicles.

2.4.2 No database maintained
      ----------------------

CarSearch System will not maintain any database of CARSEARCH equipped vehicles, 
or of CarSearch Units which have been activated.  It is instead oriented 
strictly toward individual transactions possibly involving a single CarSearch 
Unit; upon completion of any transaction, it will log that transaction to its 
printer for reference by the user.

The only permanent or long-term data CarSearch System will maintain is system 
configuration information, such as the phone numbers of its various remote 
devices.  (See section 3.4) A customer database is to be provided by the user in
the format he selects.

2.4.3 No security, encryption, authentication
      ---------------------------------------

CarSearch System will make no effort to encrypt or otherwise secure from 
discovery the CarSearch "secret numbers" or other data it deals with.

2.4.4 No system diagnostics
      ---------------------

CarSearch Systems will not diagnose or report any system problems, other than 
reporting success or failure of phone calls made to remote devices.  (See 
section 3.2.4.6)

2.4.5 No automatic broadcasts
      -----------------------

When the central computer notifies a remote device or the need for broadcasting 
some signal or test tone, the remote device will (promptly) perform the required
broadcast once; no repeats will occur other than by getting the central computer
to make phone calls for another specific request, as a result of specific 
operator action.
<PAGE>
 
                   3 SECTOR ACTIVATION COMPUTER REQUIREMENTS
                   -----------------------------------------

Following are requirements relating to the system for CarSearch System:

3.1 Hardware platform
    -----------------

The central computer will be an IBM AT-compatible computer with at least 1 Mb of
RAM and a standard BIOS. The system will contain the following peripherals:

    .    a keyboard
    .    a VGA or compatible color video monitor
    .    a permanent storage device such as a hard disk, at least 2 megabytes 
         of capacity
    .    a standard floppy disk drive, for system loading & debugging
    .    a COM1 and a COM2 device
    .    a Hayes 1200-baud modem or compatible
    .    an LPTI (parallel) port with attached printer.

The computer and its peripherals will be dedicated to use by CarSearch System; 
use for any other systems is not supported.

3.2 User Interface
    --------------

The user interface will allow the user repeatedly to specify one of 5 
transactions: Set Time, Update Phone List, Activate, Deactivate, and Test Tone. 
The interface will be presented in English. Details:

3.2.1 Main Menu
      ---------

The user interface will display a (titled) main menu, offering the choice of the
5 transactions noted, as well as possible termination of the program, and 
including display of current time and date (at least to the minute) as known to 
the computer. User selection of an action will be by some convenience means.

While the computer is awaiting user selection, it will update the displayed time
and date appropriately. When a valid user selection has been made, the 
appropriate screen will be presented for the selected transaction, as described 
in following sections.

During interaction for any user selection, time and date need be displayed only 
as explicitly noted. When the interaction for any user selection other than 
termination of the program is completed, the computer will return to displaying 
the main menu.

3.2.2 Set Time
      --------

If Set time is chosen, the user interface will accept a new date and time from 
the user, to be used henceforth by the computer, or course updated by the 
passage of time.
<PAGE>
 
Changes of time and date, showing old and new values, will be logged (see 
section 3.5).

3.2.3  Update Phone List 
       -----------------

If update Phone List is chosen, the user information will display the current 
list of phone numbers used by the central computer, and allow the user to add,
remove, or modify entries in the list.

The displayed list will always contain 8 items, some of which may be blank. To 
add an entry, user fills in data for some currently blank entry. To remove an
- - ---                                                                 ------
entry, user modifies it to all blanks.

The user may specify any printable characters in phone list entries. The user 
interface will do no checking for reasonableness of the entries.

Modifications to the phone list, with old and new entry, will be logged (see
section 3.5).

The phone list will be maintained in a permanent file (section 3.4) so that 
when the program is stopped and restarted, the last version of the phone list 
will be available and used.

3.2.4  Activate, Deactivate, Test Tone
       -------------------------------

To Activate, Deactivate, Test Tone choices all have many aspects in common, so 
are treated together in the following subsections:

3.4.2.1  Activate chosen
         ---------------

If Activate is chosen, the user interface will accept a seven-character 
activation code and a five character reply code. These codes will be validated 
for correct syntax, and the user reprompted if either is invalid. The user may 
then choose whether the transaction is to be sent to all the VATs or just one 
VAT.

3.2.4.2  Deactivate chosen
         -----------------

If Deactivate is chosen, the user interface will accept a seven-character
deactivation code. This code will be validated for correct syntax, and the user
reprompted if invalid. The user may then choose, whether the transaction is to
be sent to all the VATs or just one VAT.

3.2.4.4  Calling to remote devices
         -------------------------

Following full valid specification of a transaction (Activate or Deactivate, or 
Test Tone) the central computer will then attempt to notify the selected VATs;
see section 3.3. The user interface is not required to accept further 
transactions, until handling of this transaction is completed or aborted.
 










<PAGE>
 
3.2.4.5  Start of each call announced
         ----------------------------

At the start of each phone call by the VAC, the user interfaces will display the
phone number being called and advise the user to wait while the call is made.  
No information about progress of the call need to be presented until the call is
completed.

3.2.4.6  Results announced and logged
         ----------------------------

Following each individual phone call (successful or not), the user interface 
will display the result of the call, specifying the phone number used.

Each phone call, with phone number and result and intended transaction, will be 
logged (See section 3.5).

3.2.4.7  User may abort phone call sequence
         ----------------------------------

After the VAC gives the results of the call, if there are any more to be made,
the VAC will check whether user has pressed any keys, and if so will allow user
to specify continuation, pause, or abort of work on the transaction.

3.3  VAT notification
     ----------------

When the user has specified an Activate or Deactivate or Test Tone transaction, 
the VAC will attempt to notify each selected VAT, using the telephone number 
currently in the phone list file (section 3.4) information (including 
transactions) transferred to VAT will be done error-free.

The VAC will call each selected phone number in turn; if it succeeds in 
connecting to it, it will deliver the transaction.  If it does not succeed in a 
reasonable time, it will consider the call failed.

Following a round of attempted phone calls to each selected SAT, if there is at
least one to which the call was not successful, the VAC will retry phone calls
to the VATs it has not yet succeeded with, in sequence, up to a specified total
number of tries. This number, NumberCallTries, will be in range 1...99 and will
be defined by either (i) an MSDOS environment variable, or (ii) a statement in a
defined configuration file.

Following any of the phone calls made, the remainder may be aborted (or paused) 
by user selection (section 3.2.4.7).

3.4  Phone list file
     ---------------

The VAC will maintain a permanent phone list, giving one entry for each of the
(8) allowed VATs. Each entry will provide space for at least (30) characters,
and may be edited at will be the user (Section 3.2.3).


  
    



<PAGE>
 
Blank entries will be interpreted to mean there is no corresponding SAT.  
Non-blank entries will be interpreted as telephone numbers (including 
Hayes-compatible command characters, such as a comma for short delay), to be 
used when attempting to call the VAT.

The permanent phone list will be retrieved for use when the main program starts.
It will properly updated whenever user completes a modification to the list.

3.5 Logging
    -------

The video screen will inform the user of the disposition of each transaction,
and in the case of Activate and Deactivate and Test Tone transactions, whether
each VAT was notified. Failed transactions will be highlighted or otherwise made
especially noticeable.

In addition, the disposition of each transaction and each notification attempt 
(to a VAT) will be logged to the printer.  See details in sections 3.2.2, 3.2.3,
3.2.4.  Each item logged to the printer will include the current time and date.

On any given occasion when the VAC attempts to log something to the printer, if 
the printer is not at that time operational, then:

     the program will continue normally, except that there may be a short delay 
(maximum 15 seconds) beyond the normal execution time;

     the item being logged will be discarded, i.e., there will be no attempt to 
save it for later printing;

     the next time an item is to be logged to the printer, the same attempt to 
log will be made.

                               4 VAT REQUIREMENTS
                                 ----------------

Following are requirements relating to each VAT for CarSearch:

4.1 Hardware Platform
    -----------------

The remote computer will be an IBM AT-Compatible computer with at least 640 Kb
or RAM and a standard BIOS. The system will contain at least the following
peripherals:

     .  an MDA or compatible video board (technically, only the video RAM is 
        required).

     .  a non-mechanical permanent storage device such as a ROMdisk, with at 
        least 1 megabyte or capacity.





<PAGE>
 
    .    a standard floppy disk, for system loading and debugging.

    .    a COM1 and COM2 device.

    .    a Hayes 1200-baud modem or compatible.

    .    a standard CarSearch VAS "silver box" (Mod/PTT controller).

    .    an appropriate radio transmitter, of up to 50 watts Rf power.

The following peripherals are optional; the software is not required to support 
them:

    .    a monitor

    .    a keyboard

The computer and its peripherals will be dedicated to use by CarSearch; use for 
any other system is not supported. The system user is required to provide 
appropriate power and environmental conditioning for the remote device 
                                    ------------
equipment. This must be done as a part of site selection.

4.2 User Interface
    --------------

Because a monitor and keyboard are optional, no user interface is required on 
the VAT. The software may write some reasonable logging/diagnostic information 
to the video RAM, which may be viewed if a monitor is attached to the remote 
device.

4.3 Call processing
    ---------------

The VAT must be capable of receiving phone calls from the VAC via its modem.

Once a connection has been made, it will process Activate and Deactivate and 
Test Tone transactions sent to it. The VAT is not required to accept more than 
                                           -----------------------------------
one transaction per call.
- - -------------------------

Transactions will be received error-free; i.e, the chance of phoneline bit 
errors converting a valid transaction into a different but valid transaction 
will, for practical purposes, be zero.

4.4 Transaction processing
    ----------------------

The various transactions will be processed as follows:
<PAGE>
 
4.4.1  Activate transactions
       ---------------------

When a VAT receives an Activate transaction, it will send a single Activate 
control signal (using the specified activation code), a single Speed-up control 
signal (using the specified reply code), and a single Antijam Disable control 
signal to its Mod/PTT, in that order.  The Activate and Speed-up signals must be
contained in separate message bursts, in the order specified; the Antijam 
Disable signal may be contained in either burst (as the last signal).  These 
signals will not be repeated.

4.4.2  Deactivate transaction
       ----------------------

When a VAT receives a Deactivate transaction, it will construct a message burst 
containing a single Deactivate control signal (using the specified activation 
code), and single Antijam Disable signal, in that order, and send the burst to 
its Mod/PTT.  These signals will not be repeated.

4.4.3  Test Tone transaction
       ---------------------

When a remote device receives a Test Tone transaction, it will tell its Mod/PTT 
to generate the specified test tone.  This test time will not be repeated.

4.4.4  Message burst timing
       --------------------

The remote device will make no effort to broadcast a control signal in a 
specific "time slot".  In general control signals will be broadcast as soon as 
practical after the VAT has determined and need therefore, but not longer than  
______ after receipt of the signal.

4.4.5  Optional logging
       ----------------

Because of video screen is optional, no logging is required of the VAT.  The 
remote device may log time-stamped transactions to the video RAM, which may be 
viewed if a monitor is attached to the remote device.

                           NON-DISCRIMINATION CLAUSE


          During the term of this contract, Contractor agrees as follows:

          (1) Contractor shall not discriminate against any employee, applicant 
for employment, independent contractor or any other person because of race, 
color, religious creed, ancestry, national origin, age or sex.

          Contractor shall take affirmative action to ensure that applicants are
employed, and that employees of agents are treated during employment, without 
regard to their race, color, religious creed, ancestry, national origin, age 
or sex. Such affirmative action shall include, but is not limited to; 
employment, upgrading, demotion or transfer, recruitment or recruitment 
advertising; layoff or termination; rates of pay or other forms of compensation;
and selection for training.

          Contractor shall post in conspicuous places, available to employees, 
agents, applicants for employment and other persons, a notice to be provided by 
the contracting agency setting forth the provisions of this non-discrimination
clause.

          (2) Contractor shall, in advertisements or requests for employment 
placed by it or on its behalf, state that all qualified applicants will receive 
consideration for employment without regard to race, color, religious creed, 
ancestry, national origin, age or sex.

          (3) Contractor shall send each labor union or workers' representative 
with which it has a collective bargaining agreement or other contract or 
understanding, a notice advising said labor union or workers' representative of 
its commitments to this non-discrimination clause. Similar notice shall be sent 
to every other source of recruitment regularity utilized by Contractor.

          (4) It shall be no defense to a finding of noncompliance with this 
non-discrimination clause that Contractor had delegated some of its employment 
practices to any union, training program, or other source of recruitment which 
prevents it from meeting its obligations. However, if the evidence indicates 
that the Contractor was not on notice of the third-party discrimination or made
a good faith effort to correct it, such factor shall be considered in mitigation
in determining appropriate sanctions.

          (5) Where the practices of a union or of any training program or other
source of recruitment will result in the exclusion of minority group persons, so
that Contractor will be unable to meet its obligations under this 
non-discrimination clause, Contractor shall then employ and fill vacancies
through other non-discriminary employment procedures.

          (6) Contractor shall comply with all state and federal laws 
prohibiting discrimination in hiring or employment opportunities. In the event
of Contractor's noncompliance with the non-discrimination clause of this
contract or with any such laws, this contract may be terminated or suspended, in
whole or in part and Contractor may be declared temporarily ineligible for
further Commonwealth contracts and other sanctions may be imposed and remedies
invoked.

          (7) Contractor shall furnish all necessary employment documents and 
records to, and permit access to its books, records, and accounts by, the 
contracting agency and the Office of Administration, Bureau of Affirmative 
Action, for purposes of investigation to ascertain compliance with the 
provisions of this clause. If Contractor does not possess documents or records 
reflecting the necessary information requested, it shall furnish such 
information on reporting forms supplied by the contracting agency.

          (8) Contractor shall actively recruit minority subcontractors or 
subcontractors with substantial minority representation among their employees.

          (9) Contractor shall include the provisions of this non-
discrimination clause in every subcontract, so that such provisions will be 
binding upon each Subcontractor.

          (10)Contractor obligations under this clause are limited to the 
Contractor's facilities within Pennsylvania or, where the contract is for 
purchase of goods manufactured outside of Pennsylvania, the facilities at which
such goods are actually produced.

State of Maryland, will administer and retain authority to change, modify, 
clarify, amend or otherwise alter the terms, conditions and/or specifications 
for the term of this Agreement.

        NOW, THEREFORE, the parties to this Agreement set forth the following as

                        SECTION A. - GENERAL PROVISIONS
                        -------------------------------

maintenance and/or other support services of equipment, communications and other
components required for a Stolen Vehicle Recovery System (hereinafter referred

<PAGE>
 
     The language of this Agreement shall be appropriately construed in such a 
manner that the singular shall include the plural and the use of feminine, 
masculine or neuter genders shall be deemed to include the genders not used.


A.2  CONTRACTOR COMMITMENTS, WARRANTIES AND REPRESENTATIONS

     Any commitment by LoJack within this Agreement will be binding upon LoJack.
Failure of LoJack to fulfill any such commitment may be cause to terminate this 
Agreement for default.  For the purposes of this Agreement, a commitment by 
LoJack includes, but is not limited to:

     a.    prices and options committed to remain in force over a specified 
           period(s) of time;

     b.    any written warranty or representation made by LoJack as to hardware
           performance and other physical, design or functional characteristics
           of a machine, electrical component or system; and,

     c.    any written representation by LoJack in a proposal, supporting
           documents, side letters or other memoranda, or negotiations 
           subsequent thereto, as to training to be provided, services to be
           performed, prices and options committed to remain in force over a
           fixed period of time or any other similar matter regardless of the
           fact that the duration of such commitment may exceed the duration of
           this Agreement.


A.3  INSTALLATION AND TESTING

     a.    LoJack will install all equipment necessary for testing on or before
           December 31, 1996.

     b.    The MSP may delay the installation date by notifying LoJack at least
           ten (10) calendar days before the installation date previously
           established.

     c.    The equipment will not be considered ready for testing until LoJack
           provides the MSP with the documentation of a successful system audit
           or a diagnostic test performed at the site which demonstrates that
           the equipment meets minimum design capabilities as specified by 
           LoJack, and after review of the documentation or test the MSP agrees
           that the equipment is ready to begin the acceptance test.

     d.    If the equipment is certified to be ready on a day prior to the
           installation date, the MSP and LoJack may elect to test the equipment
           and change the installation date accordingly.

                                       2
<PAGE>
 
     e.    If the equipment is not installed within thirty (30) calendar days
           after the original installation date, the MSP reserves the right
           to cancel this Agreement without further obligation whatsoever.

     f.    All costs and expenses incurred in connection with the transporting,
           delivery, installation and testing of the System, will be the
           responsibility of and paid for in full by LoJack.  This provision
           includes any interfaces that may be required with other computer
           systems operated by the MSP or other government law enforcement 
           entities.

     g.    All equipment installation, repair, modification, update and removal 
           will be performed at MSP facilities or at a site mutually agreed to 
           by the Commander of the MSP Motor Vehicle Division and LoJack.


A.4  DELAYS AND EXTENSIONS OF TIME

     The Contractor agrees to prosecute the work continuously and diligently and
no charges or claims for damages shall be made by it for any delays or 
hindrances from any cause whatsoever during the progress of any portion of the 
work specified in this Agreement.  Time extensions will be granted only for 
excusable delays that arise from unforeseeable causes beyond the control and 
without the fault or negligence of the Contractor, including but not restricted 
to, acts of God, acts of the public enemy, acts of the State in either its 
sovereign or contractual capacity, acts of another contractor in the performance
of a contract with the State, fires, floods, epidemics, quarantine restrictions,
strikes, freight embargoes or delays of subcontractors or suppliers arising from
unforeseeable causes beyond the control and without the fault or negligence of 
either the Contractor, subcontractors or suppliers.


A.5  RISK OF LOSS OR DAMAGE

     LoJack shall be responsible for all repairs, loss, damage or destruction of
all LoJack equipment, materials or supplies provided by LoJack. The MSP is
relieved from all risks of loss, damage or destruction of the entire LoJack
Stolen Vehicle Recovery System until clear and unrestricted title to such System
is transferred to the MSP. The MSP shall promptly notify LoJack of any loss,
damage or incident that involves LoJack equipment, materials or supplies
associated with the LoJack System. LoJack has the right to maintain insurance
coverage against loss or damage to LoJack equipment at LoJack's option and
expense. The MSP shall cooperate with LoJack and representatives of the
insurance carrier concerning maintenance of any such insurance coverage.

                                       3

A.6  CONTRACTOR RESPONSIBILITY

     If the Contractor includes equipment, maintenance or other services 
marketed by other manufacturers or vendors, it will be mandatory for LoJack to 
act as the prime contractor for the installation and maintenance of the entire 
proposed configuration.  LoJack will be considered as the sole point of contact
with regard to all Agreement stipulations to include purchase, if any, and 
maintenance of the entire configuration(s).

     Whenever any item of hardware, maintenance or other service marketed by 
another manufacturer or vendor is specifically identified by LoJack, the 
Contractor hereby warrants and represents that LoJack has made such other 
manufacturer or vendor aware of the conditions governing such product(s) and 
that said manufacturer or vendor agrees with LoJack's proposed use of such 
product(s).

     LoJack warrants and agrees that the LoJack Corporation shall act in the 
capacity of an independent contractor and in no event whatsoever as an officer, 
employee, agent, servant, joint venturer, hired person or partner of the MSP.  
LoJack further agrees to take such actions as necessary to ensure that each 
subcontractor or any other person associated with the System or its use, is made
aware of this provision and agrees in writing that this provision applies 
equally to such parties.


A.7  TAXES: FEDERAL, STATE AND LOCAL

     The MSP is exempt from federal excise and all state and local taxes.  Such 
taxes shall not be included in Agreement prices.  A tax exemption certificate 
will be furnished to LoJack upon request.

     The Contractor shall be responsible for all federal, state and local taxes 
applicable to it and for the employer's share of any FICA contributions for its 
employees.


A.8  PATENT/COPYRIGHT/TRADE SECRET PROTECTION

     LoJack, at its own expense, will defend any suit which may be brought 
against the MSP for the infringement of United States patents, copyrights or 
trade secrets arising from LoJack's or the MSP's use of any equipment, materials
or information prepared or developed in connection with the performance of this 
Agreement and in such suit, LoJack will satisfy any final award for any 
infringement.  This is upon the condition that:

     a.    LoJack is notified of the suit within a reasonable time after the MSP
           becomes aware of it; and,

                                       4
<PAGE>
 
     b.   LoJack has the full right and opportunity to conduct the defense of
          any such action. If, however, principles of governmental or public law
          are involved, the MSP may at its option, participate in the defense of
          any such action.

     LoJack shall not indemnify the MSP against any claim of infringement 
arising out of equipment made or modified by an agency to its own specification 
or design, or any infringement that results from the combination of equipment 
furnished hereunder with any equipment not supplied by LoJack.

     If in LoJack's opinion the equipment, material, information or services 
furnished hereunder is likely to or does become the subject or claim of 
infringement of United States patents, copyrights or trade secrets, then without
diminishing LoJack's obligation to satisfy said final award, the Contractor may,
at its option, substitute for the alleged infringing equipment, modifications 
suitably satisfactory to the MSP, or at LoJack's option and expense, obtain the 
right for the MSP to continue the use of such equipment.  If the use of such 
equipment by the MSP shall be prevented by permanent injunction or LoJack's 
inability to procure the right for the MSP to continue using the equipment, 
LoJack agrees to take back the infringing equipment, materials or information 
and refund the total amount, if any, the MSP had paid LoJack under this 
Agreement.


A.9  NON-APPROPRIATION

     If the General Assembly fails to appropriate funds or if funds are not 
otherwise made available for continued performance for any fiscal period of this
Agreement succeeding the first fiscal period, this Agreement shall be canceled 
automatically as of the beginning of the fiscal year for which funds were not 
appropriated or otherwise made available; provided, however, that this will not 
affect either the MSP's rights or the Contractor's rights under any termination 
clause in this Agreement.  The effect of termination of this Agreement hereunder
will be to discharge both the Contractor and the MSP from future performance of 
the Agreement, but not from their rights and obligations existing at the time of
termination.  The Contractor shall be reimbursed for the reasonable value of any
non-recurring costs incurred but not amortized in the price, if any, of this 
Agreement.  The MSP shall notify the Contractor as soon as it has knowledge that
funds may not be available for the continuation of this Agreement for each 
succeeding fiscal period beyond the first.

     In the event funding is subject to the availability of Federal funding and 
such Federal funding is not made available, this Agreement may be terminated 
effective the date of non-availability of funds for those items dependent on 
Federal funds.

A.10  SUBCONTRACTING AND ASSIGNMENTS

      The Contractor may not subcontract or assign, in whole or in part, any 
portion of this Agreement without the written consent of the MSP. Such consent 
shall not be unreasonably withheld. This provision shall not prevent the 
Contractor from assigning their respective rights under this Agreement to any 
entity owned or controlled by LoJack.

A.11  MARYLAND LAW PREVAILS

      This Agreement shall be governed by and interpreted in accordance with the
laws of the State of Maryland. In the event that any portion of this Agreement 
conflicts with the laws of the State of Maryland, the affected portion of this 
Agreement shall be subject to such changes as are necessary to bring it into 
compliance with the laws, notwithstanding such provisions, the remainder of this
Agreement shall remain in full force and effect.

A.12  ENTIRE AGREEMENT

      This Agreement and all executed attachments constitute the entire 
agreement between the parties with respect to the subject matter of this 
Agreement. Any prior agreements which may exist are hereby superseded with 
respect to equipment, training and/or maintenance services acquired by the MSP 
under the terms and conditions of this Agreement.

      Any Contractor's terms and conditions that are, or may be, set forth on 
any invoice or subsequently added by the Contractor, including any terms and 
conditions packaged with or accompanying Contractor's supplied product(s), 
inclusive of third party product(s), or otherwise set forth in any manner, are 
not part of this Agreement.

A.13  AMENDMENTS

OBLIGATIONS AFTER TERMINATION:
- - ------------------------------

     LoJack recognizes that applicable law and regulations may require that
subsequent MSP contracts for continuation of the LoJack System or another stolen
vehicle recovery system, if available, after termination of this Agreement may
be based upon competitive bidding. The MSP has concerns regarding persons who
then will have purchased and installed LoJack unit transmitters in their
personal vehicles. The MSP intends to require that all bidders propose a stolen
vehicle recovery system which will continue to enable the LoJack units to
function as part of the continuing system ("compatible system"). In recognition
of the MSP's concern that any such "compatible system" may infringe on LoJack
patents or other proprietary technology, LoJack hereby agrees to license the
bidder selected by MSP to use the technology in the State of Maryland. Such
license to be as

                                      26

<PAGE>
 
broad as is required to avoid such infringement.  LoJack further agrees that it 
will charge no higher total royalty (inclusive of initial payment, if any, and 
continuing royalties), than is reasonable in the circumstances, taking into 
account the extent of the technology required, the cost of developing the same 
and the size of the relevant market.

        The MSP's obligation to utilize the System in accordance with the 
provisions of this Agreement shall not prevent the MSP from testing, using or 
procuring other stolen vehicle recovery systems, if available, as it may desire 
during the term of this Agreement.

MSP PROJECT MANAGER:
- - --------------------

        The MSP shall act as the project manager for coordinating the 
installation and utilization of the LoJack System in the State of Maryland and 
assist, where possible, in the coordination of the Stolen Vehicle Recovery 
System.  Also, the MSP must request of the Massachusetts CHSB, approval to 
utilize the Massachusetts Stolen Vehicle Recovery System for the computer
interface to initiate the activation of State of Maryland LoJack equipped
vehicles.

        The MSP project manager shall be:

                   Lt. Robert L. Scruggs
                   Bureau of Drug and Criminal Enforcement
                   (410) 290-0050 Ext. 305

        The MSP reserves the right to redesignate the project manager at any 
time during the term of this Agreement.

        The MSP responsibilities as project manager shall include the following:

        a.  Shall be responsible in conjunction with the Contractor for
            obtaining state approval for any required federal communication
            licensing applications to operate a Stolen Vehicle Recovery Network
            using the LoJack System within the State of Maryland. Any out of the
            pocket costs regarding this application shall be at the expense of
            LoJack.

        b.  The MSP agrees that the LoJack System being offered by LoJack is
            contingent upon approval of the Massachusetts CHSB approving a
            request by the MSP to interface with the existing Stolen Vehicle
            Recovery System presently in operation by the Massachusetts State
            Police at Police Headquarters in Boston, Massachusetts. Such
            approval is to be requested in writing by the MSP and accepted by
            the Massachusetts CHSB in writing before LoJack will initiate any
            preliminary plans to draw specifications for the Maryland Stolen
            Vehicle Recovery System or implementing a LoJack System in the State
            of Maryland.

                                      27

                         LOJACK SYSTEM ACCEPTANCE TEST
                         -----------------------------


     The LoJack System Acceptance Test shall evaluate:

     a.    the activation, "speed up" and deactivation of the LoJack receiver
           unit

     b.    the ability of the related tracking unit to detect and track

     c.    the combined effective range of the LoJack transmitting unit and the
           tracking unit receiver

     d.    the effective range of a typical activation transmitter/antenna

     e.    the user interface of the overall LoJack System with respect to
           controlling the tracking procedure and the advisory messages which
           result from a particular action

     The overall LoJack System has been divided into three (3) general areas
which are to be evaluated:


1.0  COMMUNICATIONS

     1.1   Proper operation of the NLETS communications lines between MSP and
           MARS.

           1.1.1  Test in accordance with Section 3.2.5

     1.2   NLETS response times to agency requests.  Responses should be 
           received within fifteen (15) seconds at any reasonable traffic load.

                                      29
 

<PAGE>
 
2.0  SOFTWARE

     The performance of the LoJack provided software in MARS, is highly 
dependent on the validity of the data files which it receives from MSP.  The MSP
shall perform extensive testing of the related software.  The correct 
functioning of the overall LoJack MSP System, shall be used to attest to the 
validity of all the software involved.  To resolve any discrepancies which arise
during testing, each interface transaction will be continually recorded for 
references.


3.0  FUNCTIONALITY

     3.1   Functionality tests will require three (3) vehicles to carry a LoJack
           transmitter unit and one (1) search vehicle equipped with the 
           corresponding Lojack tracking unit.  A radio voice link between the
           test center at MSP Headquarters and the search vehicle will be 
           required.  This series of tests shall test the functional behavior
           of the LoJack System with respect to:

           a.     the ability to activate a vehicle transmitter
           b.     the ability to discriminate between multiple active vehicle
                  transmitters
           c.     the ability to put a transmitter into the "speed up" mode
           d.     the ability to deactivate a vehicle transmitter

     3.2   Zero Range Test:
           ---------------

           All vehicles participating in the test shall be assembled in close
           proximity to one another to quickly determine the test objectives
           in 3.1. a. through d. above,

           3.2.1  Enter the three (3) test vehicles as stolen using an MSP 
                  National Crime Information Center (NCIC) quality control
                  terminal to enter an EV message transaction for each of the
                  three (3) test vehicles.  In addition to normal response 
                  messages to the originating terminal, the following should
                  happen:

                  a.    a "LoJack unit activated" message should be returned by
                        the MARS to the originating terminal for each EV request
                        entered.

                  b.    the transmitter on each stolen vehicle should be 
                        activated within three (3) minutes.  This will be 
                        verified by maneuvering the search vehicle to pick up 
                        the stolen vehicle(s) transmission and then reading out
                        the reply code for each vehicle.  The displayed reply
                        code on the search vehicle tracking unit should agree
                        with the reply code provided by the LoJack Corporation.

                                      30 



<PAGE>
 
           3.2.2  Using one (1) of the stolen vehicle reply codes obtained 
                  above, enter a LoJack query transaction into an MSP NCIC 
                  quality control terminal.  The following should happen:

                  a.     MARS should return a message to the originating MSP
                         terminal, stating that a car is stolen and that the
                         LoJack unit was put in the "speed up" mode for easier
                         tracking.

                  b.     The tracking unit display in the search vehicle should
                         provide an indication of the increased transmission
                         rate from the sped up transmitter in the stolen
                         vehicle. This will verify that the test vehicle
                         transmitter was actually put in the "speed up" mode.

           3.2.3  Enter a CV transaction using the related attributes, NCIC and
                  the vehicle identification number (VIN), of the stolen vehicle
                  which was just put into the "speed up" mode (above).  This 
                  will clear the vehicle as stolen in the NCIC files and result
                  in the normal response to the originating MSP terminal.  In
                  addition, the following should happen:

                  a.     MARS should send a message to the originating terminal
                         stating that the vehicle just cleared was LoJack unit
                         equipped and is now deactivated.

                  b.     The LoJack transmitter in the test vehicle just cleared
                         should turn off completely within three (3) minutes.
                         This will be confirmed by the tracking unit in the
                         search vehicle being unable to display the related
                         reply code which was displayed prior to entering the 
                         CV transaction.

                  3.2.3.1      Enter a LoJack query for the reply code of the
                               test vehicle just cleared to verify that the MARS
                               files no longer classify the vehicle as
                               activated. This should result in the MARS sending
                               a message to the originating terminal which
                               states that the vehicle is not stolen and that
                               the LoJack unit was deactivated.

           3.2.4  Repeat tests 3.2.3 and 3.2.3.1 to clear the two (2) remaining 
                  stolen test vehicles using a LV message request on one and a
                  XV request for the other.

                                      31
<PAGE>
 
     3.2.5 Modified Vehicle Test(MV):
           --------------------------

           A stolen vehicle record is created in NCIC and is then activated.
           Then another stolen test vehicle's VIN is used in a MV request to
           modify the original stolen vehicle's record in NCIC. This should
           cause the original vehicle to be deactivated and the vehicle with the
           newly updated VIN to become activated.

           3.2.5.1     Using the VIN of one (1) of the test vehicles, enter an
                       EV request via an MSP NCIC quality control terminal. This
                       should cause the test vehicle's transmitter to become
                       activated and can be verified by the related reply code
                       displayed on the search vehicle's tracking unit.

           3.2.5.2     Using the VIN of the second test vehicle, enter a MV
                       request via an MSP NCIC quality control terminal. This
                       should cause the original test vehicle transmitter to
                       become deactivated and the second test vehicle to become
                       activated. The reply code of the second test vehicle
                       should now be displayed on the search vehicle's tracking
                       unit display.

           3.2.5.3     Verify the new vehicle's status in the NCIC files. Enter
                       a LoJack query request with the reply code of the first
                       test vehicle via an MSP NCIC quality control terminal.
                       The resulting response to the terminal should indicate
                       that the vehicle is not stolen and that its transmitter
                       is being deactivated. Then enter a LoJack query request
                       with the reply code of the second test vehicle. The
                       resulting response should indicate that the vehicle is
                       stolen and that the LoJack transmitter has been sped up
                       for tracking.

           3.2.5.4     Enter a CV request to clear the second vehicle in the
                       NCIC files. This should be verified by a LoJack query by
                       reply code.

3.3   LoJack Activation Transmission Range:
      -------------------------------------

      The effective range of an activation transmitter will be dependent upon
      diverse factors; e.g., activation antenna height, the flatness of the
      surrounding terrain, man made obstruction and the radiated power of the
      antenna. The results of this test should be representative of a typical
      activation range.


                                      32

      3.3.1 Select the Maryland tower which has the LoJack activation 
            transmitter/antenna installed.

      3.3.2 Position a LoJack equipped test vehicle beyond the range of the
            selected activation transmitter site. LoJack Corporation shall
            provide this range information.

      3.3.3 Enter an EV for the test vehicle via an MSP NCIC quality control 
            terminal.

      3.3.4 Instruct the test vehicle to proceed in the direction of the LoJack
            activation transmitter site until the LoJack unit successfully
            activates. From this information and the location of the LoJack
            transmitter site on the map, the approximate activation range can be
            determined.

      3.3.5 Enter a CV request to clear the test vehicle.

                                      - 1 -
<PAGE>
 
         WHEREAS, the parties would like jointly to exploit these other
applications; and

         WHEREAS, the parties wish to form a joint venture for the purpose of
developing LJU-III and the Technology; and

         WHEREAS, the parties desire to set forth their respective interests in
the joint venture with respect to the services to be rendered and in any
profits, losses, or liabilities arising therefrom;

         NOW, THEREFORE, for valuable consideration, the receipt and sufficiency
of which is hereby acknowledged, the parties hereby agree as follows:

         1.   Formation of Joint Venture.
              --------------------------
  
              (a)  The parties hereby agree to form a joint venture (the "Joint
Venture") solely for the purposes of developing the Technology (the "Project")
and exploiting the Technology for the benefit of the Joint Venture. The Joint
Venture shall be known as "SCT Development Venture". The parties hereto are
sometimes herein referred to as "Venturers" or, where applicable, "Venturer".

              (b)  The Venturers agree to use their best efforts to carry out
the respective duties and obligations of the Joint Venture required of them, or
each of them hereunder; to protect and further the interests of the Joint
Venture; and to contribute such funds as are required of each such Venturer to
be contributed to undertake and carry out the Project as herein described.

              (c)  This Agreement shall not constitute any Venturer the
partner or agent of any other Venturer except as herein expressly provided, nor
in any manner limit the Venturers in carrying on their respective separate
businesses or activities, nor impose upon

                                      - 2 -
<PAGE>
 
any Venturer any fiduciary duty by reason of its carrying on its separate
business or activity, nor impose upon any Venturer any liability or obligation
to the other Venturer or the Joint Venture except as expressly provided herein.

              (d)  Except as otherwise expressly and specifically provided
herein, no Venturer shall have any authority to act for or to assume any
obligations or responsibility on behalf of the Joint Venture or any other
Venturer.

              (e)  Except as otherwise expressly and specifically provided
herein, no Venturer shall have the right to borrow money on behalf of the Joint
Venture or any other Venturer. No Venturer shall have the right to use the
credit of another Venturer for any purpose whatsoever.

              (f)  Subject to the provisions of Section 15, the Venture
shall terminate on December 31, 2015.

              
         2.   Contributions to the Joint Venture.
              ----------------------------------

              (a)  LVC hereby contributes $10,000 in cash, the receipt of which
is hereby acknowledged.

              (b)  Micrologic hereby contributes $10,000 in cash, the receipt of
which is hereby acknowledged.

              (c)  Working capital shall be contributed equally by the
Venturers, as provided in Section 4.

              (d)  LVC and the Joint Venture shall execute a License Agreement
substantially in the form attached hereto as Exhibit B.

                                     - 3 -
<PAGE>
 
              (e)  Micrologic and the Joint Venture shall execute a LJU-III
Development Agreement substantially in the form attached hereto as Exhibit C.

         3.   Interest in Property, Profits and Losses and Liabilities.
              --------------------------------------------------------

              (a)  All property of the Joint Venture of whatever description
("Property of the Joint Venture"), including, without limitation, accounts
receivable, cash receipts and undistributed cash used, generated or earned in
connection with the performance of the Project and proceeds of insurance and
fidelity bonds with respect to property or funds of the Joint Venture and loan
proceeds shall be deemed owned by the Joint Venture. No Venturer, individually,
shall have any ownership of or title to such property.

              (b)  The Venturers' interest in the Property of the Joint Venture
and in the Profits, Losses, Operating Deficits and liabilities of the Joint
Venture shall be shared in the following percentages ("Proportionate Shares")
namely: LVC 50% and Micrologic 50%. The Proportionate Shares of the Venturers
are subject to adjustment in the event a Venturer does not furnish its
Proportionate Share of working capital or pay its Proportionate Share of any
Operating Deficit or Loss as provided in Section 5.

              (c)  Each Venturer shall be jointly and severally liable to
third parties as to obligations of the Joint Venture; provided, however, that as
between the Venturers, each Venturer shall indemnify and save the other harmless
from and against any loss sustained or liability incurred in the performance of
or in connection with the Project or this Agreement, to the extent any such loss
or liability shall exceed such Venturer's respective Proportionate Share
thereof.

         4.   Working Capital; Bank Account.
              -----------------------------


                                     - 4 -

<PAGE>
 
              (a)  Initial working capital in the aggregate amount of $20,000
has been contributed to the Joint Venture. Thereafter additional working capital
shall be furnished by the Venturers at such times and in such amounts as may be
determined by the Venturers. All contributions to working capital by the
Venturers shall be in amounts equal to their respective Proportionate Shares.
All working capital contributed shall be repaid to the Venturer contributing the
same prior to the distribution of any Profits.

              (b)  The Venturers shall open and establish such bank account(s)
under such description or title as the Venturers may determine. All funds
contributed or advanced by the Venturers, as well as all funds received on
account of the performance of the Project and all proceeds of insurance and
fidelity bonds, shall be deposited in the bank account(s) of the Joint Venture.
Withdrawals from the bank account(s) shall be made only in such manner and form
as the Venturers may from time to time direct by such persons as are approved by
the Venturers.

         5.   Failure to Contribute; Right to Cure.
              ------------------------------------

              If any Venturer (the "Defaulting Party") shall at any time fail to
make the payments required to be made or contributed pursuant to this Agreement,
including, without limitation, contributions to working capital and
contributions on account of Operating Deficits and Losses, then:

         (i) If such failure shall occur prior to July 31, 1996, the other
Venturer (the "Non-Defaulting Party") may make such contribution and the
proportional interest of the Non-Defaulting Party shall be increased by a
percent determined by dividing the amount of the contribution made by the
Non-Defaulting Party by $803,025 and multiplying the quotient

                                     - 5 -
<PAGE>
 
by one hundred. For example, if the amount of the contribution is $26,767 and
the Non-Defaulting Party's percentage prior to the contribution is fifty percent
(50%), after the contribution the Non-Defaulting Party's percentage would be
fifty-three and one-third percent (53 1/3%) determined as follows:
26,767/803,025=1/30x100=3 1/3%+50%=53 1/3%.

         (ii) If such failure shall occur thereafter, the Non-Defaulting Party
may, within ten (10) days after written notice specifying the default and prior
to cure thereof by the Defaulting Party, without waiving or releasing the
Defaulting Party, contribute the amount in default for the account of the
Defaulting Party. If the Non-Defaulting Party does so contribute the amount in
default, the amount of such contribution, together with interest thereon at 3%
above the then current prime rate of Bank of Boston from the date of such
contribution, shall become a debt of, and be paid by, the Defaulting Party to
the Non-Defaulting Party within forty-five (45) days after written demand. If
the debt is not paid by the Defaulting Party within said forty-five (45) day
period, in addition to any other remedy or relief available to the
Non-Defaulting Party, said debt shall be deemed a lien upon and collectible out
of the Defaulting Party's interest in, and distributions from the Joint Venture.
Reimbursement of amounts paid under this Section shall have priority over
payment of any distribution to the Defaulting Party under this Agreement.

         6.   Manager. The general supervision and management of the Joint
              -------
Venture and any and all matters relating thereto shall be under the general
charge and control of a board of three managers. One such manager shall be
designated by each Venturer from among its executive officers and directors. The
Venturers together shall designate a third member of the Board of Managers who
shall not be an employee or director of either Venturer or of a

                                     - 6 -
<PAGE>
 
subsidiary or parent of either Venturer. The Board of Managers may delegate
day-to-day operating authority to one or more persons (the "Manager").
Initially, in the absence of such designation, Joseph F. Abely and Sheldon
Apsell jointly shall act as Manager. Until further or other delegation is made
by the Board of Managers, both of them, acting together as Manager shall have
the power, in the name of the Joint Venture, to execute and deliver sales
orders, purchase orders, contracts, and other agreements, and to borrow money,
obtain letters of credit and pledge Property of the Joint Venture as collateral
for obligations of the Joint Venture, except that, where any single commitment
resulting in an obligation of the Joint Venture exceeds $5,000 in amount, or the
total of such commitments then outstanding exceed $10,000 in the aggregate, the
Manager shall obtain the approval of the Venturers before executing any such
agreements. The Manager shall be given such additional specific powers as the
Venturers may from time to time delegate. Unless specifically authorized by the
Venturers, the Manager shall serve without compensation.

         7.   Venture Costs. Costs of performance of the Joint Venture ("Venture
              -------------
Costs") to be borne by the Joint Venture and shared by the Venturers shall
consist of all costs incurred pursuant to the Development Contract, all costs of
exploiting the Technology, and all administrative costs, insurance (other than a
Venturer's own general liability insurance and workers compensation insurance
relating to a Venturer's own employees which shall not be borne by the Joint
Venture), taxes, if any, imposed on the Joint Venture or the Property of the
Joint Venture, legal fees, accounting fees, liability, fidelity or casualty
losses not covered by insurance, compensation and benefits (if any, as approved
by the Venturers) of the Manager and other administrative, supervisory and
clerical personnel employed directly by

                                     - 7 -
<PAGE>
 
the Joint Venture or assigned full time to the Joint Venture, all costs
attributable to the maintenance of an office and all other expenses and
obligations incurred in connection with the performance of the Project of a kind
and nature which, under generally accepted accounting principles, would be
properly charged as an expense relating to the performance of the Project.
Except by agreement of the Venturers, the Joint Venture shall not be charged for
any overhead expenses or charges attributable to the main or branch offices of a
Venturer, nor for compensation of officers and administrative staff of a
Venturer unless assigned full time to the Project, nor for any costs associated
with the negotiation, preparation or enforcement by a Venturer of this
Agreement.

         8.   Books and Records.
              -----------------

              (a)  Separate books of account and other records relating to the
performance of the Project, the amount of Venture Costs incurred and revenue
received in the performance of the Project, the amount of each Venturer's
respective capital account, the records relating to bank accounts of the Joint
Venture and all other matters pertaining to the Joint Venture and the Project
shall be kept and maintained at the main office of the Joint Venture.

              (b)  A periodic audit (or, if agreed upon by the Board of
Directors, review) of the books and records shall be made by an independent firm
of certified public accountants or by such individuals and at such intervals as
may be agreed upon by the Venturers.

              (c)  A true and correct accounting shall be rendered by the
Manager to each Venturer monthly within thirty (30) days after the close of each
month (and at the Completion

                                     - 8 -
<PAGE>
 
of the Project) of all costs, expenses, and other data relating to the
performance of the Project and the affairs of the Joint Venture.

              (d)  Records shall be kept of each Venturer's capital account in
the Joint Venture, including, without limitation, contributions to working
capital, the amount of all distributions therefrom, and adjustments to capital
accounts resulting from defaults, if any, pursuant to Section 5.

              (e)  Each Venturer shall have the right at all reasonable times,
during usual business hours, to audit, examine, and, at its expense, make copies
of or extracts from the books and records maintained in connection with the
Project. The Venturer or Venturers requesting such inspection shall bear all
expenses incurred in any examination made for its or their account.

              (f)  The books and records of the Joint Venture shall be kept for
a period of five years after the Completion of the Project at such place or
places as the Venturers may from time to time determine. The cost of maintaining
and storing the books and records after Completion of the Project shall be borne
by the Venturers in amounts equal to their respective Proportionate Shares.

              (g)  The fiscal year of the Joint Venture shall be December 31.

         9.   Tax Status, Returns and Allocations.
              -----------------------------------

              (a)  Any provision hereof to the contrary notwithstanding, for
federal income tax purposes, each of the Venturers hereby recognizes and agrees
that the Joint Venture will be treated as a partnership in accordance with the
provisions of the United States Internal Revenue Code, as the same may from time
to time be amended; provided,

                                     - 9 -
<PAGE>
 
however, that the filing of partnership tax returns shall not be construed to
extend the purposes of the Joint Venture or expand the obligations or
liabilities of the Venturers. The Venturers shall, by mutual agreement, file any
election permitted or required under said Internal Revenue Code (the "Code") in
confirmation of the foregoing provided, however, that the Venturers shall file
an election under Section 754 of the Code on the first federal income tax return
of the Joint Venture.

              (b)  The Manager shall cause to be prepared all tax returns and
statements, if any, which are required to be filed on behalf of the Joint
Venture with the appropriate taxing authorities. Such returns and statements
shall be submitted to the Venturers for their approval prior to filing, and,
when approved by the Venturers, shall be filed promptly. The Venturers agree not
unreasonably to withhold or delay approval of tax returns.

         10.  Division of Profits.
              -------------------

              (a)  Profits or losses of the Joint Venture shall be allocated to
the capital accounts of the Venturers in proportion to their respective
ownership interests. All tax and other items separately allocated shall be
allocated in proportion to aggregate profit or loss.

              (b)  The Profits of the Joint Venture shall be distributed to
the Venturers in the discretion of the Board of Managers. All distributions
shall be in proportion to capital account balances. Either Venturer may require,
to the extent that cash is available, that a distribution shall be made to each
of the Venturers in an amount at least sufficient to pay estimated Federal and
State income taxes on the taxable income of the Joint Venture, assuming each
Venturer to be subject to such taxes at the maximum applicable effective rate,
net, in the case of Federal taxes, of the benefit of the deduction of State
taxes.

                                    - 10 -
<PAGE>
 
Further, if combined capital accounts of the Venturers exceed $1,000,000, either
Venturer may require, to the extent of available cash, a distribution to the
Venturers of an amount not more than the amount by which such combined capital
accounts exceed $1,000,000.

              (c)  As used herein, the term "Profits" shall mean the total
amount of funds of the Joint Venture:

- - -        after payment of (i) all Venture Costs and any other costs and charges
         -------------
         incurred in the performance of the Project; (ii) all other costs and
         charges provided in this Agreement to be paid or borne by the Joint
         Venture theretofore due and payable; and (iii) any and all liens and
         claims against the Project or the Joint Venture (unless covered by
         insurance and being defended, without reservation of right, by the
         insurer or unless the parties agree in good faith to contest the same
         and maintain an adequate reserve therefor as set forth below);

- - -        and after the retention of adequate and reasonable reserves for (iv)
         --------------------------
         any liens or claims which either have been brought against the Project
         or the Joint Venture and not paid or covered by insurance (but
         contested as provided above) or which are reasonably anticipated by the
         Venturers to be brought and for (v) all other monetary obligations of
         the Joint Venture or the Venturers on its behalf not then due and
         payable, including a cash reserve approximately equal to an average one
         month's operating expenses of the Joint Venture; and

- - -        after repayment to the Venturers of (vi) all sums advanced by the
         -----------------------------------
         Venturers for working capital, as adjusted for defaults as provided in
         Section 5 hereof, including repayment of advances (and interest
         thereon) made by a Non-Defaulting Party.

                                    - 11 -
<PAGE>
 
Any reserves, when no longer required, or so much thereof as shall remain, shall
be distributed to the Venturers in the amount of their respective Proportionate
Shares. This obligation shall survive the Completion of the Project.

         11.  Sharing of Losses and Operating Deficit.
              ---------------------------------------

              (a)  If the cost of performance of the Project from time to time
exceeds available cash from the sale of Product and working capital or if there
are insufficient funds, at any time, to meet accrued obligations of the Joint
Venture or the Venturers acting on its behalf ("Operating Deficit") or if, upon
Completion of the Project there are insufficient funds to make the payments and
reservations set forth in Section 10(i), (ii), (iii), (iv) and (v) ("Loss" or
"Losses"), the Venturers shall be obligated to make additional contributions of
cash or otherwise satisfy claims and obligations in the amount of their
respective Proportionate Shares of the Operating Deficit or Loss, as the case
may be. The liability of the Venturers for Losses shall continue with respect to
any claims which at any time, either before or after the Completion of the
Project, shall be made against them or either of them or the Joint Venture by
reason of the Joint Venture or the Project or this Agreement.

              (b)  Any deficit in the account of a Venturer by reason of its
failure to contribute its required proportion of the Operating Deficit or Loss
shall be subject to the provisions of Section 5 as a failure to contribute
working capital.

         12.  Insolvency. In the event a Venturer shall institute proceedings or
              ----------
consent to proceedings requesting relief or an arrangement under the Federal
Bankruptcy Code or any similar or applicable federal or state law; or if a
petition under any federal or state bankruptcy or insolvency law is filed
against a Venturer and such petition is not dismissed

                                    - 12 -
<PAGE>
 
within sixty (60) days from the date of said filing; or if a Venturer admits in
writing its inability to pay its debts generally as they become due; or if a
Venturer makes a general assignment for the benefit of its creditors; or if a
receiver, liquidator, trustee or assignee is appointed on account of its
bankruptcy or insolvency; or if a receiver of all or any substantial portion of
a Venturer's properties is appointed; or if a Venturer fails to perform promptly
and diligently its obligations under this Agreement; or if a Venturer is a
Defaulting Party and payments are made on its behalf under Section 5; then, from
and after the date of such event, such Venturer shall cease to have any voice in
the management of the Joint Venture and the Project and all acts, consents, and
decisions with respect to the Joint Venture and the Project shall thereafter be
taken solely by the other Venturer. The Venturer thus prohibited shall, however,
remain liable for its Proportionate Share of Losses, Operating Deficits and
liability for obligations of the Joint Venture, including those arising or
accruing after the date of such prohibition.

         13.  Assignment. Neither this Agreement nor any interest of a Venturer
              ----------
herein (including any interest in the Property of the Joint Venture) may be

              (b)  Upon receipt of such written notice and offer, the Offeree
shall, within a period of ten (10) business days thereafter, give notice in
writing to the Offeror of its election to negotiate for the purchase of the
Offered Interest. Thereafter, for a period not to exceed 45 days after such

              (c)  If the Offeree shall have elected not to negotiate, or if
the parties shall have been unable to reach agreement within the 45 day period
specified in subsection (b) hereof, then if the dispute between the parties
relates to valuation, the issue of valuation shall be determined by arbitration
in the City of Boston pursuant to the Rules for Commercial Arbitration of the
American Arbitration Association. Valuation, as so determined, shall be binding
upon the parties for all purposes. If the dispute is other than as to valuation,

arbitration, then the Venture shall be liquidated.

              (d)  Nothing herein shall prevent any of the Venturers hereto from

transfer, mortgage, pledge, lease or other disposition of any Venturer's
interest herein, including a judicial or involuntary sale or transfer, or a
transfer by operation of law, the purchaser or transferee shall be bound by all
of the terms and conditions of this Agreement, and by

    calculated at the Company's effective tax rate which was (19.2%) for 
    fiscal 1996 and 7.1% for fiscal 1995. The difference between the Company's
    effective tax rate and the United States statutory rate is due primarily to
    the utilization of loss carryforwards and the change in the valuation
    allowance.

(b) These figures agree with the related amounts in the statements of
    operations.

(c) This calculation is submitted in accordance with Regulation S-K item
    601(b)(11) although, it is contrary to paragraph 40 of APB Opinion No. 15
    because it produces an anti-dilutive result.

LoJack Corporation markets and licenses the LoJack System, a unique, proprietary
system used exclusively by law enforcement personnel to track, locate, and
recover stolen motor vehicles.

The problem of vehicle theft has escalated to an epidemic level - estimated to 
result in an annual loss of almost $8 billion.

The LoJack System has a proven track record of reducing damage, enhancing public
safety, and solving serious crimes related to motor vehicle theft, all
accomplished within the practical constraints of today's overburdened law
enforcement system.

LoJack's strategy is to expand the use of its technology into those U.S. and
international markets where the combination of population density, new car
sales, and vehicle theft is high.

The LoJack System is currently operational in the following states: California,
Connecticut, District of Columbia, Florida, Georgia, Illinois, Maryland,
Massachusetts, Michigan, New Jersey, New York, Pennsylvania, Rhode Island,
Texas, and Virginia.

International licensees are operating stolen vehicle recovery systems using
LoJack's technology in the following countries: Argentina, Colombia, Czech
Republic, Ecuador, Greece, Hong Kong, Kenya, Korea, Panama, Russia, Slovak
Republic, South Africa, Tobago and Trinidad, United Kingdom, and Venezuela.

On May 12, 1997, there were 4,300 record holders of the Company's Common Stock.
The Company believes the actual number of beneficial owners of shares of the
Common Stock is approximately 28,000 because a large number of the shares are
held in custodial or nominee accounts for the benefit of persons other than the
record holder.

LoJack has never paid a dividend, and at the present time, the Company expects
that future earnings will be retained for use in its business or to repurchase
shares of its Common Stock. The Company's loan agreement with a bank permits the
payment of dividends so long as such payment does not cause noncompliance with
certain loan covenants.

Overview

     I recently had the opportunity to visit our licensees of the LoJack
Technology in Argentina and South Africa. My visits to these distant parts of
the world, and my observations of the exciting and intense start-up efforts
experienced by these two licensees provided me an opportunity to reflect on the
incredible progress and success that LoJack Corporation has achieved. Over the
past eleven years we have built a strong foundation for the LoJack Technology
that sets the stage for our continued growth into the future. We produced
revenues of over $61 million during our fiscal year ended February 28, 1997
("Fiscal 1997"). More importantly, this past year we continued to invest in
establishing our Stolen Vehicle Recovery Network, which today includes fourteen
states, plus the District of Columbia. In addition, our licensees presently
operate the LoJack Technology in 15 foreign countries.

     It gives me great pleasure to outline for you our accomplishments over the
past year and to give some insights into our future plans. We produced solid
financial results while completing domestic expansion to Maryland, Pennsylvania
and Texas, with additional expansions within the existing states of California
and Florida. On the international front, we extended our coverage to include
South Africa, Korea, Kenya and Panama. It is of equal importance to recognize
that our research and development efforts have produced efficiencies in our
technology which provide us the opportunity to expand coverage on an
economically feasible basis to a broader geographic area than was originally
planned. We are also nearing completion of the development of the LJU III
product, a self-powered version of the LoJack Unit, which we hope will be the
catalyst for expansion into the fleet, rental and commercial markets. We believe
that this product and our enhanced geographic coverage represent significant
opportunities for the company's continued growth.

Fiscal 1997 Results

     For fiscal 1997, revenues increased 17% to $61,665,000, compared to
$52,616,000 a year ago. Operating income for fiscal 1997 was $11,920,000, an
increase of 39% over $8,605,000 in fiscal 1996. Net income was $8,180,000, or
$.36 per share. Fiscal 1996's net income of $11,978,000, or $.51 per share,
included a non-recurring credit for income taxes of $2,654,000. The company's
effective tax rate for fiscal 1997 was reported on a fully taxed basis of 39%,
compared with a net tax benefit of 19% a year ago. Pro forma net income for
fiscal 1996 would have been $6,129,000, or $.26 per share, had taxes been
calculated at the fully taxed rate of 39%.

                                   [PHOTOGRAPH OF C. MICHAEL DALEY APPEARS HERE]

     The increase in our revenues reflects a $5,265,000, or 119%, increase in
revenues from our international licensing activities, and a $3,884,000, or 8%
increase in revenues from our domestic operations. Our overall gross margin, as
a percentage of revenues, increased to 55% from 54% a year ago. It is important
to note that domestically in fiscal 1997 there were no new markets opened. In
addition, our cost of sales and operating expenses in fiscal 1997 included costs
and expenses relating to our expansion into Maryland, Pennsylvania, and Texas,
all of which became fully operational in fiscal 1998.

     We realize that the increase in our effective tax rate to a fully taxed
rate of 39% in fiscal 1997, coupled with the large tax credit in fiscal 1996,
made comparisons of the company's performance for the two years somewhat
confusing. Fortunately, in the fiscal year ending February 28, 1998 (fiscal
1998), our effective tax rate is expected to be the same as in fiscal 1997,
which should provide a more realistic comparison of our results.

     In fiscal 1997, we generated $12,879,000 in cash flow from operations,
which helped enhance our already strong financial position. This strength gave
us the opportunity to undertake a stock repurchase program. Through May 12,
1997, we have repurchased 3,065,000 shares of our common stock. We believe that
this program represents a good investment and utilization of cash, and will
contribute to enhancing shareholder value.

Fiscal 1998

     It is exciting to report that we are off to a very strong start in the
first two months of fiscal 1998, which we hope will be a good indication of the
potential results for the coming year.

     We will be ramping up our sales in Maryland, Pennsylvania and Texas. These
markets increase the portion of the U.S. retail new car and light truck market
served by LoJack by approximately 30% over fiscal 1997. We believe that the
potential in these new markets represents a solid revenue growth opportunity for
the company in fiscal 1998.

     In addition, we are undertaking over the next two years to expand into
markets contiguous to existing LoJack coverage areas as well as to markets that
have a higher incidence of auto theft. Present plans include Ohio, Delaware,
southern New Hampshire, and several key metropolitan areas such as
Tucson/Phoenix, St. Louis, Denver and northern California.

     In our new markets, we have improved our advertising program to include
greater frequency and more focused content and we are testing other media in
addition to our traditional drive time radio format. We have evaluated and are
improving our sales organizations in several markets and have strengthened our
training program. We believe that these changes will improve our sales results
over the coming year.

     Internationally, our licensee in South Africa commenced operations during
the third quarter of fiscal 1997, and our licensees in Korea and Kenya have
commenced operations in the first quarter of fiscal 1998. Of note, affiliates of
licensees in South Africa and Korea, Rembrant Group and Samsung Corporation,
respectively, both are major multinational companies. We are excited about the
potential of these markets. In addition, some of our international licensees
have arrangements with Jaguar, Fiat, Vauxhall, Mercedes Benz and BMW for the
installation of LoJack Units. Finally, we expect that growth will be healthy in
our international area with fourteen additional countries under agreement.
Licensees in Germany, Mexico, Brazil, China and several additional countries in
South America are making significant progress, with the potential for several of
them to open sometime during fiscal 1998.

     As I write this letter, LJU III is going through production validation
testing, and barring any unforeseen delays, we estimate that this product could
be ready for manufacturing by year end. The LJU III is equipped with a self-
contained power supply and antenna, and will have a lower installed cost than
the current LoJack Retrieve Unit. This product will not differ functionally from
our existing product. We feel this product increases the number of potential
applications for use of the LoJack System. We will initially market the LJU III
to fleet, commercial, and car rental operators, which we feel present a growth
opportunity as well as an introduction into an underdeveloped market segment for
our system. We have also recently completed the development of a version of our
current LoJack Unit for use by the heavy equipment industry which will be ready
to market in the coming year.

     We are enthusiastic about our prospects for fiscal 1998. Domestically, we
believe that the stage is set for increased growth in our existing markets, and
that new markets will start to contribute meaningful revenue growth
progressively over the course of the year. Our international licensees are
performing well, and we estimate that our growth in that area will be strong
throughout the year.

The Future

     LoJack is one of the few companies in the highly fragmented automotive
aftermarket that has an established brand name and brand equity, distribution
channels, advertising presence and installation capability in most major US
markets. Now that we have attained that position, we are continually seeking
potential niche products to more effectively utilize our aftermarket
installation organization and distribution networks. We are currently evaluating
several potential research and development projects which will assist our
expansion program and growth, including technologies to increase our coverage
over a broader nationwide area. We are aggressively looking at ways to lower the
cost of our products to make them more affordable to consumers as well as
compatible for automobile manufacturers to utilize in the production line
environment.

Conclusion

     It is encouraging to note that the LoJack System continues to be the only
proven technology for Stolen Vehicle Recovery in the world. A number of
competitive systems have attempted but failed to equal the success we have
achieved with our system.

     The major elements of our domestic success are that our product is operated
exclusively by law enforcement and that there are no hidden charges or ongoing
monitoring fees to our customers.

     Finally, a recent article in Business Week discusses an independent study
by the National Bureau of Economic Research which gives a substantial boost to
the LoJack Technology. The study suggests that there is a major deterrent effect
in the states that have the LoJack System. The study also states that there are
significant economic benefits to be realized by society as a whole as the result
of reduced auto theft due to the use of the LoJack System. The study encourages
expansion of the system and makes the suggestion that the insurance industry
should take a more aggressive interest in its growth.

     On behalf of the Officers and Directors of LoJack Corporation, I would like
to express our appreciation to the many loyal and dedicated employees who are a
part of the LoJack Family. It is because of their efforts and dedication to our
mission that the Company has been so successful. I know with their continued
commitment and this unique technology we are positioned for a promising and
prosperous future.

Yours truly,

/s/ C. Michael Daley

[TRAFFIC PICTURE   Management's Discussion and Analysis of
APPEARS HERE]      Financial Condition and Results of Operations


     LoJack is the developer of, and owns all rights to, the LoJack System, a
unique patented system designed to assist law enforcement personnel in locating,
tracking, and recovering stolen vehicles. The LoJack System is comprised of a
Registration System maintained and operated by LoJack; a Sector Activation
System and Police Tracking Computers operated by law enforcement officials (the
"Law Enforcement Components"); and the LoJack Unit, a VHF (very high frequency)
transponder sold to consumers. The LoJack System is designed to be integrated
into existing law enforcement computer and telecommunication networks and
procedures. If a car equipped with a LoJack Unit is stolen, its owner reports
the theft as usual to a local police department. Existing law enforcement
computer and communication networks and procedures operate in the normal manner
for a report of a stolen vehicle. If the theft involves a vehicle equipped with
a LoJack Unit, a unique radio signal will be transmitted automatically to the
LoJack Unit in the stolen vehicle activating its tracking signal. The tracking
signal emitted from the LoJack Unit can be detected by the Police Tracking
Computer installed in police patrol cars throughout the coverage areas and is
used to lead law enforcement officers to the stolen vehicle.

The Company's revenues in the United States are derived primarily from the sale
of LoJack Units and related products to consumers. Approximately 95% of such
sales are made through a distribution network consisting of new and used
automobile dealers.

The Company also derives revenues from fees, sales of product, and royalties
pursuant to agreements to license ("License Agreements") the use of the
Company's stolen vehicle recovery system technology, principally to selected
international markets. In connection with this international expansion, the
Company modified its stolen vehicle recovery technology to develop the CarSearch
Stolen Vehicle Recovery System ("CarSearch"). Unlike the LoJack System currently
in operation in the United States, CarSearch has the flexibility of operating
independently of existing law enforcement communication networks.

Results of Operations
Year ended February 28, 1997 ("fiscal 1997")
vs. February 29, 1996 ("fiscal 1996")

Revenues increased by $9,149,000 or 17% in fiscal 1997 to $61,665,000 from
$52,516,000 in fiscal 1996. Revenues from domestic markets contributed
$3,884,000 of the increase and international revenues contributed $5,265,000.
The increase in domestic revenues was primarily due to increased revenues from
sales of LoJack Units and related components in existing domestic markets. The
increase in international revenues of $5,265,000 resulted primarily from an
increase in the sales and royalties of the international version of the LoJack
Unit and related products of $2,839,000 which are primarily recurring in nature,
as well as an increase in revenues from the sale of system components and
licensing fees of $2,426,000, which are primarily both non-recurring in nature
and related to new licensees.

Cost of goods sold decreased to 45% of consolidated revenues in fiscal 1997 from
46% for the same period a year earlier. Domestically cost of goods sold
decreased as a percentage of revenues to 45% in fiscal 1997 from 46% in fiscal
1996. The decrease results primarily from a decrease in the manufactured cost of
the LoJack unit as well as installation efficiencies realized from economies of
scale resulting from increased product sales. International cost of goods sold
increased to 43% of revenues in fiscal 1997 from 40% in fiscal 1996.

Systems costs and research and development expense increased by $54,000 to
$1,317,000 in fiscal 1997 from $1,263,000 in fiscal 1996. Research and
development expense increased by $2,000 to $518,000 in fiscal 1997 from $516,000
in fiscal 1996. Fiscal 1997 expense was primarily related to the ongoing
development of a third generation LoJack Unit, while fiscal 1996 research and
development expense related to modifications to the LoJack Unit for
international applications and the Police Tracking Computer. Systems costs
increased by $52,000 to $799,000 in fiscal 1997 from $747,000 in fiscal 1996 due
to an increased number of domestic markets and increased age of the LoJack
System in established markets.

Overall, marketing expenses remained at 21% of total revenues. Marketing
expenses increased by $1,731,000 to $12,943,000 in fiscal 1997 from $11,212,000
in fiscal 1996. These increases were primarily related to an increase in media
expense due to increased radio advertising in certain markets, as well as start-
up expenses (including personnel and media planning) related to expansion
activity in Maryland, Pennsylvania, and Texas. Additionally, sales and marketing
salaries and wages and other general marketing expenses increased as the result
of an increase in overall business volume.

Overall, general and administrative expenses as a percentage of revenues
decreased to 10% in fiscal 1997 as compared to 11% in fiscal 1996. General and
administrative expenses increased by $709,000 to $6,284,000 in fiscal 1997 from
$5,575,000 in fiscal 1996. These increases are primarily the result of increased
payroll costs and administrative expenses related to the increased domestic and
international

volume during the year, as well as start-up expenses related to expansion
activity in Maryland, Pennsylvania and Texas.

Depreciation and amortization decreased  by $399,000 as the result of LoJack
System components in certain older markets becoming fully depreciated, offset
partially by increases in depreciation related to current year additions of
computer equipment and software.

Interest and other income increased by $29,000 primarily as the result of the
increase in average cash balances related to cash flow from operations during
the first half of fiscal 1997, partially offset by the decrease in average cash
balances during the second half of fiscal 1997 related to increased activity in
the Company's stock repurchase program.

Interest expense decreased by $13,000 due to a decrease in the average capital
lease obligations outstanding in fiscal 1997 as compared to fiscal 1996.

Provision for income taxes increased by $7,155,000 for fiscal 1997 primarily as
the result of both the increase in the Company's taxable income during the
fiscal year as well as an increase in the Company's effective tax rate to 39% in
fiscal 1997. The Company had a net tax benefit of 19% for fiscal 1996 primarily
as the result of a non-recurring credit for income taxes.

Year Ended February 29, 1996 ("fiscal 1996") vs. February 28, 1995 ("fiscal
1995")

Revenues increased by $10,858,000, or 26%, in fiscal 1996 to $52,516,000 from
$41,658,000 in fiscal 1995. Revenues from domestic markets contributed
$8,872,000 of the increase and international revenues contributed $1,986,000.
The increase in domestic revenues was primarily due to increased revenues of
approximately $8,338,000 from sales of LoJack Units and related components in
domestic markets, including $3,500,000 from new markets which began operations
in fiscal 1996. The increase in international revenues of $1,986,000 resulted
from an increase in revenues from sales and royalties of the international
version of the LoJack Unit of $1,070,000 to both new and existing licensees,
with the balance of the increase from the non-recurring sale of components and
license fees principally from new licensing agreements with parties in foreign
countries including Russia, Argentina, and South Africa.

Cost of goods sold decreased to 46% of consolidated revenues in fiscal 1996 from
50% in fiscal 1995. Domestically cost of goods sold decreased as a percentage of
revenues to 46% in fiscal 1996 from 50% in fiscal 1995. This decrease is
primarily the result of a decrease in the manufactured cost of the LoJack Unit
during the year. Additionally, reductions in cost of goods sold were due to
installation efficiencies resulting from the economies of scale. International
cost of goods sold decreased to 40% of revenues in fiscal 1996 from 50% in
fiscal 1995 primarily as the result of revenues being weighted towards higher
margin component sales and license fees.

Systems costs and research and development increased by $456,000 to $1,263,000
in fiscal 1996 from $807,000 in fiscal 1995. Research and development expense
increased by $185,000 as a result of expenses related to the development of
certain improvements and modifications to the LoJack Unit and the Police
Tracking Computer, and other projects which commenced during fiscal 1996.
Systems costs increased by $271,000 primarily as a result of increased system
operating costs related to the fiscal 1995 expansion markets which were in
operation for a full year in fiscal 1996, as well as increases in systems
maintenance costs and maintenance engineering salaries related to updating and
repairing existing LoJack Systems.

Marketing expenses increased by $1,933,000 to $11,211,000 in fiscal 1996 from
$9,278,000 in fiscal 1995 primarily as the result of increases in marketing
wages and benefits and increases in general marketing expenses, including
advertising costs, as the result of both a full year of operations in the fiscal
1995 expansion markets, the start-up of new markets in fiscal 1996, and an
increase in marketing spending related to the increase in overall business
volume during the year in existing domestic markets.

General and administrative expenses increased by $705,000 to $5,575,000 in
fiscal 1996 from $4,870,000 in fiscal 1995, primarily due to the addition of
certain administrative personnel and related office, telephone, insurance and
other expenses necessary to accommodate the demands of the increase in the
Company's business volume, legal and other fees resulting from the Company's
international expansion and other non-recurring matters, as well as a full year
of operations for the fiscal 1995 expansion markets.

Depreciation expense decreased by $399,000 as the result of LoJack System
components in certain older markets becoming fully depreciated. This decrease is
offset partially by increases in depreciation related to fiscal 1995 and fiscal
1996 start-up markets as well as current year additions of certain computer
equipment and software.

Interest and other income increased by $700,000 to $1,608,000 in fiscal 1996
from $908,000 in fiscal 1995 as the result in the increase in cash balances
available for investment during the year offset by a general decrease in average
interest rates during the year.

Interest expense decreased by $177,000 to $167,000 in fiscal 1996 from $344,000
in fiscal 1995 primarily due to the inclusion of additional interest expense in
fiscal 1995 related to a guarantee under a former line of credit.

The income tax provision (benefit) decreased by $2,226,000 to a benefit of
$1,931,000 in fiscal 1996 from a provision of $295,000 in fiscal 1995. This
decrease resulted from an increase in the current provision of $428,000 as the
result of the increase in taxable income during the fiscal year, offset by a 
non-recurring credit for income taxes of $2,654,000.

As a result of the foregoing, net income increased by $8,140,000 to $11,978,000
in fiscal 1996 from $3,838,000 in fiscal 1995.

[TRAFFIC PICTURE             Liquidity and Capital Resources
APPEARS HERE]

The Company's strategic plan in the United States is to expand the use of its
technology to those jurisdictions where the combination of new vehicle sales,
population density, and the incidence of vehicle theft is high. Expansion of the
LoJack System in the United States requires substantial investments of capital
and operating resources. The Company currently finances its capital and
operating needs from cash flow from operations and capital leases. During fiscal
1995 and prior years, the Company financed such needs through the issuance of
common stock, convertible debentures, and long-term debt.

In fiscal 1997 cash and equivalents decreased by $16,959,000. The overall
decrease is the result of cash outlays for financing of $25,961,000 and
investing of $3,877,000 being partially offset by cash flow from operating
activities of $12,879,000.

Cash used for financing activities included $25,356,000 related to the
repurchase of the Company's stock under a stock repurchase program approved
during fiscal 1996 and amended during fiscal 1997, as well as repayment of
capital leases of $1,008,000 offset by proceeds from the exercise of stock
options of $403,000.

Cash used for investing activities included a purchase of short-term investment
of $1,600,000 as well as expenditures for property and equipment of $2,277,000
(excluding assets purchased under capital lease agreements.)

Cash flow provided by operating activities of $12,879,000 includes net income of
$8,180,000 and $4,699,000 of adjustments to reconcile net income to net cash
provided by operating activities. The decrease in cash from changes in assets
and liabilities of $1,898,000 includes an increase in accounts receivable of
$1,780,000, an increase in inventories of $965,000, an increase in prepaid
expenses of $70,000 and a decrease in other assets of $11,000 and accrued and
other liabilities of $133,000, offset partially by increases in accounts payable
of $279,000, and deferred revenue of $782,000. The increase in accounts
receivable is primarily related to a $1,603,000 increase in receivables related
to international sales substantially all of which were secured under the terms
of letters of credit and paid in March 1997. The Company expects its investment
in accounts receivable will increase as its sales increase. The increase in
inventory is primarily the result of a $690,000 increase in international
inventory, as well as a $275,000 increase in domestic inventory levels. The
international inventory was increased to satisfy orders which were primarily
shipped during March and April 1997, whereas the domestic increase related to
efforts to increase inventories on hand to sufficient levels to satisfy the
Company's current level of business, anticipated sales in expansion markets of
Maryland, Texas and Pennsylvania, as well as to meet unanticipated demand. The
increase in deferred revenue is related to cash received during the year under
the extended warranty program for which revenue is amortized over a five year
period.

The Company is presently pursuing expansion efforts in several additional
markets which meet the qualifications set forth in the Company's strategic plan.
The Company expects that, pending receipt of necessary approvals, certain of
these potential expansion markets may become operational during fiscal 1998. The
Company plans to fund these expansions as well as other capital expenditures
during fiscal 1998, using the existing working capital, cash flow from
operations, or line of credit. The Company estimates capital expenditures in
fiscal 1998 of approximately $3,100,000 (excluding assets purchased under
capital lease agreements) principally for planned and anticipated domestic
market expansions, including Pennsylvania and Texas, as well as other on-going
capital requirements, including an investment to upgrade the Company's
information systems.

The Company's expansion into additional international markets is achieved
through licensing agreements and has not in the past required capital investment
on the part of the Company. The Company currently has no plans to change this
practice.

As of February 28, 1997 the Company had working capital of $21,883,000. The
Company believes that its anticipated capital and operating requirements for
fiscal 1998 can be funded from cash flows from operations and, if necessary, the
existing line of credit. The Company intends to continue to repurchase shares of
its common stock provided that the purchase price makes such repurchases
economically practical. The Company's existing line of credit with a bank of
$7,500,000 was amended during the third and fourth quarters of fiscal 1997
primarily to convert it from a secured facility to an unsecured facility, and to
extend the revolving credit facility term to March 1998 at which time any then
outstanding balances would convert to a term loan payable in quarterly
installments through February 2003.

During fiscal 1996 the Company's Board of Directors authorized a stock
repurchase program under which the Company may repurchase up to 2,200,000 shares
of its outstanding common stock, which subsequently was increased to 3,200,000
on January 3, 1997 and to 5,200,00 in May, 1997. As of February 28, 1997 the
Company had repurchased 2,569,500 shares for a total of $26,203,658. From
February 28, 1997 through May 12, 1997 the Company has repurchased an additional
496,000 shares at a cost of $4,997,808.

The Company continues to participate in research and development efforts that
will lead to improvements and modifications to the LoJack Unit and LoJack System
components. The Company estimates it will spend approximately $750,000 in fiscal
1998 on its research and development efforts as compared with $518,000 spent in
fiscal 1997.

The Company is also continuing to explore possible investment opportunities,
including, but not limited to, possible acquisitions of or investments in other
companies.

[TRAFFIC PICTURE              New Accounting Pronouncements
APPEARS HERE]                     and Cautionary Statements

New Accounting Pronouncements

During fiscal 1997 the Company adopted Statement of Financial Accounting
Standard ("SFAS") No. 121 "Accounting for the Impairment of Long-Lived Assets
and for Long-Lived Assets to be Disposed of" and SFAS No. 123 "Accounting for
Stock-Based Compensation". The implementation of SFAS No. 121 did not have a
significant impact on the financial statements when adopted in fiscal 1997. The
Company, as permitted under SFAS No. 123, did not adopt the fair value method
for the measurement and recognition of employee stock-based transactions and
continues to use Accounting Principles Board Opinion No. 25. In February 1997
the Financial Accounting Standards Board issued SFAS No. 128, "Earnings per
Share" which will become effective during the fourth quarter of fiscal 1998.
SFAS No. 128 replaces the presentation of primary earnings per share with a
presentation of basic earnings per share, which excludes dilution, and requires
the dual presentation of basic and diluted earnings per share. Had the Company
used SFAS No. 128, the Company's basic earnings per share would have been $.39,
$.56 and $.17 for fiscal 1997, 1996 and 1995, respectively. Diluted earnings per
share would have been the same as the earnings per share presented in the
consolidated statements of operations.


Cautionary Statements

The Private Securities Litigation Reform Act of 1995 contains certain safe
harbors regarding forward-looking statements. From time to time, information
provided by the Company or statements made by its employees may contain 
"forward-looking" information which involve risk and uncertainties.

Any statements in this report that are not statements of historical fact are
forward-looking statements (including, but not limited to, statements concerning
the characteristics and growth of the Company's market and customers, the
Company's objectives and plans for future operations and the Company's expected
liquidity and capital resources). Such forward-looking statements are based on a
number of assumptions and involve a number of risks and uncertainties, and
accordingly, actual results could differ materially. Factors that may cause such
differences include, but are not limited to: the continued and future acceptance
of the Company's products and services, the rate of growth in the industries of
the Company's customers; the presence of competitors with greater technical,
marketing and financial resources; the Company's ability to promptly and
effectively respond to technological change to meet evolving customer needs;
capacity and supply constraints or difficulties; and the Company's ability to
successfully integrate new operations. For a further discussion of these and
other significant factors to consider in connection with forward-looking
statements concerning the Company, reference is made to Exhibit 99 of the
Company's Annual Report on Form 10-K for the fiscal year ended February 28,
1997.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS YEARS ENDED FEBRUARY 28, 1997,
FEBRUARY 29, 1996 AND FEBRUARY 28, 1995

1. THE COMPANY AND SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

The Company - LoJack Corporation and subsidiaries ("LoJack" or the "Company")
market and license for use components of the LoJack System (the "LoJack System")
and related products, a unique proprietary system for tracking, locating, and
recovering stolen vehicles.

Summary of Significant Accounting Policies

Fiscal Year - The Company's February 1997, 1996, and 1995 fiscal years ended on
February 28, 1997, February 29, 1996, and February 28, 1995, respectively.

Principles of Consolidation - The consolidated financial statements include the
accounts of LoJack and its wholly owned subsidiaries. Intercompany transactions
and balances are eliminated in consolidation.

Use of Estimates - The management of the Company is required, in certain
instances, to use estimates and assumptions that affect the amounts reported in
the consolidated financial statements, and the notes thereto, in order to
conform with generally accepted accounting principles. The Company's actual
results could differ from these estimates.

Revenue Recognition - Sales of the LoJack Units and related products are
recognized upon installation by the Company. Revenues from the sale of products
and components of the LoJack System to licensees are recognized upon shipment.

Nonrefundable fees received in connection with the granting of licenses to
implement and operate components of the LoJack System are generally recognized
upon receipt of the fees or, in the case of deposits, once they became
nonrefundable. Such revenues aggregated approximately $1,168,000, $932,000, and
$163,000 for the fiscal years ended February 1997, 1996, and 1995, respectively.
LoJack's sole obligation in connection with the granting of licenses is to
provide technical assistance on a fee-for-service basis.

Revenues from sales of extended warranties are amortized over the estimated term
of the warranties (five years). Revenues from extended warranty sales expected
to be realized beyond one year are classified as a long-term liability. Costs
directly related to the sales of such warranties are deferred and charged to
expense proportionately as the revenues are recognized. Such revenues aggregated
approximately $855,000, $570,000 and $334,000 for the fiscal years ended
February 1997, 1996 and 1995, respectively. The related warranty costs are
recognized when incurred.

Research and Development - Costs for research and development on components of
the LoJack System have been expensed as incurred. Such costs aggregated
approximately $518,000, $516,000 and $330,000, for the fiscal years ended
February 1997, 1996 and 1995, respectively.

Certain Concentrations - The Company has subcontracted one supplier to
manufacture certain LoJack System components (including police tracking
computers) as well as to perform certain research and development. The Company
also conducts certain research and development through an equally owned joint
venture between the supplier and a subsidiary of the Company. The Company's
subsidiary reimburses the joint venture for fifty percent of the research and
development costs incurred. Such reimbursed costs are included as research and
development expense in the consolidated statements of operations. The Company
also has subcontracted the manufacturing of the LoJack Unit to another supplier.
The Company believes that other suppliers have the capability to perform these
services, but that changing suppliers may cause delays and additional costs to
the Company.

Cash Equivalents - Cash equivalents include short-term, highly liquid
investments purchased with remaining maturities of three months or less. These
cash equivalents consist of high quality securities purchased through major
banks. Management routinely assesses the financial strength of the banks and, as
of February 28, 1997, believes it had no significant exposure to credit risks.

Short-Term Investment - Short-term investment consists of a floating rate demand
security with a final maturity of greater than three months. The Company has a
continuous option to have the security redeemed at par value at any seven day
interval.

Accounts Receivable - The allowance for doubtful accounts was approximately
$553,000 and $395,000 as of the end of February 1997 and 1996, respectively.
Domestic receivables are principally due from new and used automobile dealers
that are geographically dispersed in various states. International receivables
are primarily secured by letters of credit and are related to fees, sales of
product, and royalties pursuant to licensing agreements.

Inventories - Inventories are stated at the lower of cost (first-in, first-out
method) or market and consist primarily of finished goods, including LoJack
Units and other related products and components held for resale.

Property and Equipment - Property and equipment are stated at cost. Depreciation
and amortization are calculated using the straight-line method over the
estimated useful lives of the related assets (three to seven years).

Deferred Contract and Patent Costs - Deferred contract and patent costs,
included in other assets, are being amortized using the straight-line method
over periods ranging from 3 to 17 years.

Fair Value of Financial Instruments - The Company's financial instruments
consist of cash and equivalents, a short-term investment, accounts receivable,
accounts payable, deposits, accrued liabilities, and capital lease obligations.
The fair value of these financial instruments at the end of February 1997 and
1996 approximate their carrying values.

Product Warranty Costs - Anticipated costs related to standard product

Income Taxes - Effective March 1, 1994, the Company adopted Statement of
Financial Accounting Standard ("SFAS") No. 109, "Accounting for Income Taxes."
SFAS 109 requires recognition of deferred tax liabilities and assets for the
expected future tax consequences of events that have been included in the
Company's financial statements or tax returns. Deferred tax liabilities and
assets are determined based upon the difference between the financial statement
carrying amounts and the tax basis of existing assets and liabilities, using
enacted tax rates in effect in the year(s) in which the differences are expected
to reverse.

Earnings Per Share - Earnings per share has been computed by dividing net
income, after reduction for preferred stock dividends, by the weighted average
number of common shares and equivalents outstanding. Common share equivalents
included in the computation represent shares issuable upon assumed exercise of
stock options (and stock purchase warrants for fiscal 1995), which would have a
dilutive effect. Fully diluted and primary earnings per share were the same for
the years ended February 1997, 1996 and 1995.

Accounting for Long-Lived Assets - The Financial Accounting Standards Board
("FASB") has issued SFAS No. 121, "Accounting for the Impairment of Long-Lived
Assets and for Long-Lived Assets to Be Disposed Of." This statement establishes
accounting standards for the impairment of long-lived assets, certain
identifiable intangibles, and goodwill related to those assets to be held and
used and for long-lived assets and certain identifiable intangibles to be
disposed of. The Company adopted this standard in fiscal 1997. The adoption did
not have a material effect on the Company's consolidated financial position or
results of operations.

Accounting for Stock-Based Compensation - The Company accounts for stock-based
compensation using the intrinsic value method in accordance with Accounting
Principles Board Opinion No. 25.

New Accounting Pronouncement - In February 1997, the FASB issued SFAS No. 128,
"Earnings per Share" which will become effective during the fourth quarter of
fiscal 1998. SFAS No. 128 replaces the presentation of primary earnings per
share with basic earnings per share, which excludes dilution, and requires the
dual presentation of basic and diluted earnings per share. Had the Company used
SFAS No. 128, the Company's basic earnings per share on a proforma basis would
have been $0.39, $0.56 and $0.17 for fiscal 1997, 1996 and 1995, respectively.
Diluted earnings per share would have been the same as the earnings per share
presented in the consolidated statements of operations.

Supplemental Disclosures of Cash Flow Information - Cash payments for interest
aggregated approximately $154,000, $168,000 and $672,000 for the fiscal years
ended February 1997, 1996 and 1995, respectively. Cash payments for income taxes
for the fiscal years ended February 1997, 1996 and 1995 were approximately
$1,064,000, $418,000 and $244,000, respectively.

Supplemental Disclosures of Noncash Investing and Financing Activities - Capital
lease obligations aggregating approximately $1,168,000, $879,000 and $1,299,000
were incurred when the Company entered into lease agreements for new vehicles
and equipment during the fiscal years ended February 1997, 1996 and 1995,
respectively.

In July 1995, $100,000 of the Company's 10% convertible subordinated debentures
were converted into 23,506 shares of the Company's common stock.

Reclassifications - Certain 1996 and 1995 amounts have been reclassified to
conform to the 1997 presentation.

4. LINE-OF-CREDIT AND CAPITAL LEASE OBLIGATIONS

Line-of-Credit - The Company has an unsecured line-of-credit agreement with a
bank which provides for borrowings up to a maximum of $7,500,000. This facility
permits borrowings and repayments through March 1, 1998, at which time the line-
of-credit converts to a term loan which requires quarterly installments of
principal commencing on May 31, 1998 and ending on February 28, 2003.
Outstanding borrowings under the line-of-credit bear annual interest, payable
monthly, at the bank's base rate. No borrowings were outstanding under the line-
of-credit as of the end of February l997 and 1996.

The line-of-credit agreement generally contains limitations on indebtedness,
certain investments in equity securities and entity acquisitions; requires
lender's approval of mergers; and prohibits disposition of assets other than in
the normal course of business. Additionally, the Company is required to maintain
certain financial performance measures including debt service coverage, minimum
tangible capital funds, and profitability.

The payment of dividends and repurchase of the Company's common stock is
permitted and is limited only to the extent such payments affect the Company's
ability to meet the financial performance measures under the line-of-credit.

Capital Lease Obligations - The Company has entered into capital lease
arrangements for certain vehicles and equipment. The cost of leased vehicles and
equipment included in property and equipment was approximately $3,986,000 and
$2,946,000, and the related accumulated amortization was approximately
$2,326,000 and $1,447,000 as of the end of February 1997 and 1996, respectively.
Amortization of such assets is included within depreciation and amortization
expense in the accompanying consolidated financial statements. At February 28,
1997, scheduled repayment requirements for capital lease obligations are as

As described in Note 1, the Company uses the intrinsic value method to measure
compensation expense associated with grants of stock options to employees and
non-employee directors. Had the Company used the fair value method to measure
compensation for options granted subsequent to February 28, 1995, reported net
income and earnings per share would have been as follows:

<TABLE>

<S>                                                <C>            <C>

  Earnings per share                              $      0.29     $      0.49 
</TABLE>

Options granted during fiscal 1997 and 1996 had a weighted average grant date
fair value of $8.47 and $5.58, respectively. The fair value of options on their
grant date was measured using the Black/Scholes option pricing model. Key
assumptions used to apply this pricing model were as follows:

<TABLE>
<CAPTION>
                                                       1997           1996
<S>                                                <C>            <C>
  Range of risk free interest rates               6.51% - 6.87%  5.81% - 7.06%
  Expected life of option grants                     9 years        9 years
  Range of expected volatility of underlying
   stock                                            51% - 53%      44% - 51%
</TABLE>

It should be noted that the option pricing model used was designed to value
readily tradable stock options with relatively short lives. The options granted
to employees are not tradable and have contractual lives of up to ten years.
However, management believes that the assumptions used to value the options and
the model applied yield a reasonable estimate of the fair value of the grants
made under the circumstances.

Stock Repurchase Plan - During fiscal 1996, the Company's Board of Directors
authorized a stock repurchase plan (the "Repurchase Plan"). The Repurchase Plan,
as amended, authorizes the Company to purchase up to 3,200,000 shares of its
outstanding common stock. As of February 28, 1997, the Company repurchased
2,569,500 shares for a total of $26,203,658.

Stock Purchase Warrants - During the year ended February 28, 1995, 3,092,425 of
stock warrants were exercised resulting in net proceeds to the Company of
approximately $13,185,500. There were no stock warrants outstanding as of the
end of February 1997, 1996, and 1995.

SFAS No. 109 requires a valuation allowance against deferred tax assets, if
based on available evidence, it is more likely than not that some or all of the
deferred tax assets will not be realized. As of February 28, 1995, the Company
believed that uncertainty existed with respect to future realization of the net
deferred tax assets and established a valuation allowance for the full amount.
Changes in the valuation allowance for the years ended February 1996 and 1995
resulted in a decrease to the Company's tax provision of approximately
$5,854,000 and $1,381,000, respectively, primarily attributable to the
utilization of net operating loss carryforwards and the Company's determination
that, as of the end of February 1996, the valuation allowance was no longer
necessary. Accordingly, the income tax provision for the year ended February 29,
1996 included a credit provision of approximately $2,654,000 related to the
elimination of the valuation allowance for the deferred tax assets. Tax benefits
that pertained to certain employee stock option exercises of approximately
$265,000 and $2,049,000 were recorded to additional paid-in capital for the
fiscal years ended February 1997 and 1996, respectively.

The Company has investment tax and research and development credit carryforwards
aggregating approximately $140,000 at February 28, 1997, which expire in varying
amounts through 2001. The Company also has approximately $530,000 in alternative
minimum tax credits at February 28, 1997. These credits may be used to offset
future federal income tax liabilities, if any. The maximum amount of operating
loss and tax credit carryforwards available in any one year may be limited under
existing tax law.

Recovery System, Inc. ("RSI"), a subsidiary of the Company, has available for
tax purposes a net operating loss carryforward of approximately $799,000 at
February 28, 1997. This loss may be used to offset future taxable income of RSI,
if any, which may otherwise be subject to federal income tax, and expires in
varying amounts through 2005. As a result of the acquisition of RSI by LoJack,
the maximum amount of RSI carryforwards available in any one year will be
limited under existing tax law.

7. COMMITMENTS AND CONTINGENT LIABILITIES

Lease Commitments - The Company leases various facilities under operating leases
whose terms expire from 1998 to 2002; the leases contain renewal options ranging
from two to five years. Minimum annual lease payments are as follows:

     Total                                                 $ 1,937,000

</TABLE>                                                        

Rental expense under operating leases aggregated approximately $844,000,
$786,000 and $721,000 for the fiscal years ended February 1997, 1996 and 1995,
respectively.

Other Commitments - The Company made a payment of $500,000 of contingent
interest in fiscal 1995 to a third-party guarantor under a previous line-of-
credit to the Company. The Company has no further contingent liabilities under
this agreement.

8. EMPLOYEE BENEFIT PLAN

The Company has a defined contribution 40l(k) plan covering substantially all
full-time employees. Under the provisions of the plan, employees may contribute
a portion of their compensation within certain limitations. The Company matches
a percentage of employee contributions on a discretionary basis as determined by
the Board of Directors. The Company's Board of Directors elected to match 40% of
employee contributions in both fiscal 1997 and 1996 and 25% in fiscal year 1995,
subject to certain limitations. Company contributions become fully vested after
five years of continuous service. Company contributions related to the plan were
$139,000, $133,000 and $59,000 for the fiscal years ended February 1997, 1996
and 1995, respectively.

9. EXPORT SALES

                         Independent Auditors' Report
                         ----------------------------

To the Board of Directors and Stockholders
of LoJack Corporation:

We have audited the accompanying consolidated balance sheets of LoJack
Corporation and subsidiaries as of February 28, 1997 and February 29, 1996, and
the related consolidated statements of operations, stockholders' equity, and
cash flows for each of the three years in the period ended February 28, 1997.
These financial statements are the responsibility of the Company's management.
Our responsibility is to express an opinion on these financial statements based
on our audits. 

We conducted our audits in accordance with generally accepted auditing
standards. Those standards require that we plan and perform the audit to obtain
reasonable assurance about whether the financial statements are free of material
misstatement. An audit includes examining, on a test basis, evidence supporting
the amounts and disclosures in the financial statements. An audit also includes
assessing the accounting principles used and significant estimates made by
management, as well as evaluating the overall financial statement presentation.
We believe that our audits provide a reasonable basis for our opinion.

In our opinion, such consolidated financial statements present fairly, in all
material respects, the financial position of LoJack Corporation and subsidiaries
as of February 28, 1997 and February 29, 1996, and the results of their
operations and their cash flows for each of the three years in the period ended
February 28, 1997 in conformity with generally accepted accounting principles.
