                       OMNITRACS(R) TERMS AND CONDITIONS


1.   OMNITRACS EQUIPMENT.

1.1. DELIVERY; PURCHASE OF ADDITIONAL EQUIPMENT. The OmniTRACS Mobile Messaging
Communications Terminals ("MCTs") and accessory equipment ordered under this
Agreement (collectively the "Equipment"), as set forth on Page 1, shall be
delivered in accordance with Attachment 2, Delivery Schedule. All Equipment is
shipped FOB QUALCOMM's San Diego facility. Risk of loss in transit and the cost
of any cargo insurance shall be borne by Customer. During the Term, provided
Customer is in compliance with the terms and conditions set forth in this
Agreement, Customer may order the additional Equipment described on Page 1,
subject to the pricing and other terms set forth therein, and any other
accessories, parts or services offered by QUALCOMM at QUALCOMM's then current
list price, upon delivery to QUALCOMM of Customer's valid purchase order
specifying the desired product and quantity. QUALCOMM will confirm such order
with Customer and the parties shall schedule a mutually agreed upon delivery
date for such order in accordance with the terms and conditions of this
Agreement, including but not limited to those set forth in the Delivery
Schedule.

1.2. ACCEPTANCE AND TITLE. Inspection and acceptance of the Equipment shall
occur within fifteen (15) days after the date of shipment. Customer shall
receive title to all deliverable Equipment (excluding the firmware resident in
the MCTs described in Section 1.4 below), only upon QUALCOMM's receipt of
complete and full payment. QUALCOMM shall be entitled to affix tags, decals, or
plates to the Equipment indicating QUALCOMM as the manufacturer of the Equipment
and displaying any QUALCOMM trademarks.

1.3. INSTALLATION OF MCTS. The MCT installation price described on Page 1 does
not include the price of the Outdoor Unit Mounting Bracket and is conditioned
upon installation occurring at the rate of both (i) a minimum of five (5)
vehicles per day per two (2) man crew (one bay) per facility, and (ii) a minimum
of twenty-five (25) vehicles per two (2) man crew (one bay) per facility during
a five (5) consecutive day period. In the event Customer does not provide the
minimum number of vehicles required in this Section, Customer shall pay
QUALCOMM, in addition to the installation price per MCT, an amount equal to the
sum of $125.00 multiplied by the number of vehicles below the minimum vehicle
availability requirement set forth herein. No MCTs will be installed by QUALCOMM
using Outdoor Unit Mounting Brackets which are not provided by QUALCOMM or which
do not meet the specifications set forth in the bracket specification manuals
published from time to time by QUALCOMM. Any other Outdoor Unit Mounting Bracket
proposed for use by Customer shall be approved in advance by QUALCOMM's
mechanical engineering staff as meeting or exceeding minimum design standards,
subject to the payment by Customer of any costs incurred by QUALCOMM in
performing the analysis necessary for such approval.

QUALCOMM warrants that for thirty (30) days from the date on which the Service
(as defined in Section 3.1 below) is first initiated for any MCT installed by
QUALCOMM, such MCT will provide the Service. In the event such MCT fails to
provide the Service during such thirty (30) day period and QUALCOMM determines
that such failure is due to improper installation, then as Customer's sole and
exclusive remedy, QUALCOMM will provide free of charge the necessary parts and
labor to correct the installation.

1.4. FIRMWARE. Customer acknowledges that software is resident in the MCTs and
in certain other accessory Equipment which may be provided to Customer hereunder
("Firmware"), and that access to and use of which shall be governed by the
general provisions relating to Software set forth in Sections 2.1, 2.3, and 2.4
below.

1.5. EQUIPMENT WARRANTY. QUALCOMM warrants that upon shipment and continuing for
a period of [DELETED months thereafter (the "Warranty Period"), the major MCT
components (which are the Outdoor Unit, Communication Unit and Display Unit),
shall be free from material defects in materials or workmanship and capable of
providing the Service ("Good Working Order") (collectively the "Warranty").
Customer shall remove and return at its expense and risk of loss (unless
otherwise directed by QUALCOMM) the failed MCT or, preferably, the component
thereof which is not in Good Working Order, to QUALCOMM, and QUALCOMM shall
perform maintenance in accordance with the Maintenance Procedures described
below and return a replacement MCT unit (or component) free of charge to
Customer during the Warranty Period. QUALCOMM's warranty obligation is limited
to repair or replacement of defective or non-performing MCT components as
required to restore the item to Good Working Order. The Warranty is provided for
the benefit of Customer only, and is not transferable by Customer without the
express consent, in advance, by QUALCOMM. All other goods, including but not
limited to goods not manufactured by QUALCOMM (such as cables and mounting
brackets) are expressly excluded from the Warranty. Any such goods not
manufactured by QUALCOMM shall be covered by the applicable manufacturer's
warranty, if any, and QUALCOMM's sole obligation in connection therewith shall
be to use reasonable efforts to assist Customer in obtaining such warranty
service, at Customer's expense.

1.6. WARRANTY EXCLUSIONS. QUALCOMM excludes from the Warranty and has no
obligation to repair or replace any MCT which is not in Good Working Order due
to: (i) use of the MCT with software, cable connections, or mounting brackets,
other than those furnished by QUALCOMM or approved by QUALCOMM, which approval
shall not be unreasonably withheld; (ii) damage to antennas, radomes (including
painting) or other equipment resulting from physical impact or other abuse
following delivery FOB QUALCOMM's San Diego facility; (iii) improper handling of
any component of the OmniTRACS System, including Software, or (iv) alteration,
modification or repair other than pursuant to QUALCOMM's advance written
instructions or by QUALCOMM. Customer further acknowledges that the Outdoor Unit
and the Communication Unit of the MCT have been sealed and that if the seal is
broken on any of these units the Warranty is voided for that MCT. In the event
that any returned MCT is not in Good Working Order due to any of the provisions
listed in the preceding two (2) sentences, the Warranty shall be considered void
and all such maintenance action will be billed at either the Out-of-Extended
Maintenance Rates set forth on Page 1 or the then current spare parts price, as
currently set forth in Attachment 1, at QUALCOMM's sole discretion.

1.7. EXTENDED MAINTENANCE AND OUT-OF-EXTENDED MAINTENANCE SERVICE. After the
expiration of the Warranty Period, Customer may elect to obtain QUALCOMM's
Extended Maintenance Service on a fleetwide basis only, by paying for Extended
Maintenance Service with the first invoice for monthly Extended Maintenance
Service fees at the rates set forth on Page 1. QUALCOMM will begin invoicing
Customer for Extended Maintenance Service one (1) month prior to the expiration
of the Warranty Period for the first MCT or lot of MCTs shipped to Customer.
Under the Extended Maintenance Service, QUALCOMM shall provide continued
Warranty service for Customer's MCTs during the remainder of the Term at the
Extended Maintenance Rate. QUALCOMM reserves the absolute right to terminate the
Extended Maintenance Service without prior notification to Customer in the event
that (i) Customer has not paid the applicable charges in accordance with the
provisions of this Agreement or (ii) the Extended Maintenance Service is not
maintained without interruption, for any reason, for all initiated MCTs in
Customer's possession for which the Warranty Period has expired. QUALCOMM also
reserves the right to refuse Extended Maintenance Service after expiration of
the Term, to condition the availability thereof upon the upgrade of MCTs and
other Equipment, at Customer's expense and/or to increase the prices for
Extended Maintenance Service. In the event that Customer has not elected the
Extended Maintenance Service, Customer will be billed on a per failure basis at
the Out-of-Extended Maintenance Rates set forth on Page 1 ("Out-of-Extended




                                       3
<PAGE>   4



Maintenance Service"). The Out-of-Extended Maintenance Rates are valid only for
repairs which would otherwise qualify under the Warranty. QUALCOMM's obligation
to provide Extended Maintenance Services or Out-of-Extended Maintenance Services
to Customer is contingent upon Customer removing and returning at its expense
and risk of loss the MCT or component thereof requiring such service to
QUALCOMM. QUALCOMM shall not be obligated to perform any Extended Maintenance
Service or Out-of-Extended Maintenance Service if the MCT is not in Good Working
Order as a result of Customer's improper or negligent use of the Equipment which
causes physical damage, or which otherwise would be excluded from the Warranty,
and Customer shall pay QUALCOMM for such service an additional amount equal to
either the Out-of-Extended Maintenance Rates or the then current spare parts
price as currently set forth in Attachment 1, at QUALCOMM's sole discretion.

1.8. MAINTENANCE PROCEDURES. All Warranty repairs, Extended Maintenance Service
and Out-of-Extended Maintenance Service by QUALCOMM will be accomplished at
QUALCOMM's facility or other QUALCOMM designated site in accordance with
QUALCOMM's then current OmniTRACS Advance Replace RMA Procedure, as updated from
time to time at QUALCOMM's discretion. Customer shall be responsible for all
costs associated with the removal of the MCTs or components thereof, including
all shipping costs to QUALCOMM, all risk of loss in transit, and the
installation of the replacement MCTs or components. QUALCOMM shall advance
replace MCTs or components after proper notification by Customer that the MCT or
component thereof is not in Good Working Order. Proper notification (orally or
in writing) will be deemed to have occurred when Customer has contacted
QUALCOMM's Customer Service Center and been assigned a Return Material
Authorization Number ("RMA") for the MCT or component thereof deemed not to be
in Good Working Order. QUALCOMM shall use its best efforts to advance replace
any defective or non-performing item within seventy-two (72) hours after
receiving proper notification, provided such notification is received at
QUALCOMM during the normal work week (Monday through Friday and prior to 2:00
p.m. Pacific Time), excluding national holidays. For notification received
outside the normal work week or during a national holiday, QUALCOMM shall use
its best efforts to repair or replace any defective or non-performing item
within a target of one hundred and twenty (120) hours. The replacement component
or MCT, which may be previously used or repaired items, will be shipped to the
Customer's operations center or other Customer designated facility and receipt
of such at the Customer operations center or other Customer designated facility
constitutes replacement, at which time title to such replacement component or
MCT shall vest in Customer if and to the same extent that title to the replaced
component or MCT was vested in Customer. Replacement components or MCTs shall be
subject to the greater of the remaining Warranty term applicable to the replaced
component or MCT or a sixty (60) day service warranty beginning as of the date
such replacement item is shipped.

Title to the defective or non-performing items shall automatically be reassigned
to QUALCOMM if the exchanged item is owned by Customer. The assigned RMA shall
be clearly visible on each shipping form and associated shipping carton. Failure
to have this RMA will result in the immediate return of all items to Customer.
The defective or non-performing items shall be returned to QUALCOMM within
fourteen (14) days after assignment to Customer of the RMA. Failure to return
such items during this period will result in Customer being invoiced the higher
of the then current QUALCOMM price or the applicable spare parts price as
currently set forth in Attachment 1. In addition, Customer will be notified that
QUALCOMM will discontinue its "advance replace" RMA policy for Customer and
future RMAs will be considered "no advance replace;" that is, replacement
components for future RMAs will not be shipped until the failed components have
been returned. At the time that all past due components are received by QUALCOMM
or paid for in full in accordance herewith, QUALCOMM will resume advance
replacement of failed MCTs and components.

1.9. UPGRADE WARRANTY. In the event any MCT or component is upgraded for
purposes of refurbishment or to add a feature, such upgrade will be completed in
accordance with QUALCOMM's Advance Replace RMA Procedure, unless otherwise
agreed by the parties. Any such upgraded MCT or component shall be subject to
the remaining Warranty term applicable to the upgraded MCT or component, or if
such item was not covered by Warranty, such MCT or component shall be covered by
a sixty (60) day upgrade warranty beginning as of the date such upgrade is
shipped.

1.10. NO RIGHT TO DISTRIBUTE OR REMARKET. No right is granted to Customer
hereunder to distribute or remarket Equipment, and QUALCOMM reserves the right
to refuse to provide the Service to any person obtaining the Equipment from
Customer without QUALCOMM's prior written consent.

2.   OMNITRACS SOFTWARE.

2.1. SOFTWARE LICENSE. The term "Software" as used herein, includes all software
licensed to Customer by QUALCOMM pursuant to the provisions of this Agreement,
including Firmware as described in Section 1.4, and any documentation delivered
in connection with such software. QUALCOMM grants to Customer a non-exclusive,
non-transferable, revocable license to use the Software solely in conjunction
with the OmniTRACS System, and (i) with respect to Software other than the
Firmware, at one (1) location (the "Site") and (ii) on one (1) Customer
controlled or owned central processing unit and operating system software, both
meeting QUALCOMM's specifications for use with the Software (the "Authorized
Equipment"). QUALCOMM further grants to Customer the right to transfer its
license to use the Firmware during the useful life of the Equipment, in
conjunction with the transfer of its ownership subject to the limitations of
Section 1.10, provided that prior to the transfer of the Equipment, the
transferee shall agree in writing to treat the Firmware as confidential
proprietary information of QUALCOMM, and to observe all copyright and trademark
rights of QUALCOMM. Customer further acknowledges that QUALCOMM has no
obligation to provide the Service to such transferee of the Equipment nor any
other person or entity other than to Customer pursuant to the terms and
conditions of this Agreement, and that QUALCOMM may condition its agreement to
provide the Service to any transferee upon QUALCOMM's approval of the
creditworthiness of such transferee, the payment by such transferee of a
relicensing fee and/or the upgrade of Equipment at such transferee's expense.

2.2. DELIVERY, ACCEPTANCE AND INSTALLATION. QUALCOMM will ship Software ordered
hereunder FOB QUALCOMM's San Diego facility. For Software installed by QUALCOMM,
acceptance shall occur upon installation; in all other cases, acceptance of the
Software shall occur within fifteen (15) days after shipment. Unless otherwise
expressly agreed, Customer shall be responsible for installing the Software into
its Authorized Equipment at the Site. Installation of Software by QUALCOMM will
be on a time and materials basis at QUALCOMM's then current rates plus
reimbursement for travel and per diem expenses.

2.3. UNAUTHORIZED USE OF THE SOFTWARE. Customer shall not (i) alter, modify or
adapt the Software, including but not limited to translating, decompiling,
disassembling, reverse engineering or creating derivative works; (ii) copy the
Software (except that Customer may make up to (3) copies of the Software other
than the Firmware for inactive back-up and archival purposes); (iii) sublicense,
assign or otherwise transfer the Software in whole or in part (except as
otherwise provided with respect to the Firmware in Section 2.1); (iv) use the
Software on other than the Authorized Equipment at the Site, or (v) use the
Software except as specifically contemplated by and set forth in this Agreement.
Use of the Software by Customer for purposes other than the OmniTRACS System is
a material breach of this Agreement and will be subject to the prompt
application of the termination provisions set forth in Section 6.2.

2.4. PROPRIETARY INFORMATION. Customer expressly acknowledges that the entire
right and title to the Software, including but not limited to all copyright,
trade secret and other intellectual or proprietary rights to the Software, shall
remain with QUALCOMM, and QUALCOMM has the exclusive right (i) to 




                                       4
<PAGE>   5

protect the Software by copyright registration or otherwise and (ii) to
reproduce, publish, display, sell and distribute such Software to anyone.
Customer shall not remove any copyright notices or any confidential or
proprietary legends from the Software. Customer also hereby acknowledges and
agrees that the Software constitutes a valuable proprietary product and trade
secret of QUALCOMM embodying substantial creative efforts and confidential
information, ideas and expressions. Accordingly, Customer shall observe complete
confidentiality with respect to the Software, and shall not disclose all or any
portion of the Software to any third party or entity, except as such disclosure
may be necessary or appropriate to Customer's employees in the course of their
employment. Customer shall advise any employees of Customer receiving access to
the Software of the confidential and proprietary nature of the Software and
obtain from each of such employees his or her agreement to abide by the
obligations of Customer set forth in Sections 2.3 and 2.4.

2.5. SOFTWARE WARRANTY. The Software has been developed to permit Customer to
use the MCTs and access QUALCOMM's Network Management Facility computer(s) and
to perform other related functions. QUALCOMM warrants that for a period of
twelve (12) months (the "Software Warranty Period"), each Software product shall
perform substantially in accordance with the specifications contained in the
applicable Software manuals (the "Software Warranty"). For Software installed by
QUALCOMM, the Software Warranty Period shall commence upon installation; in all
other cases the Software Warranty Period shall commence upon shipment. QUALCOMM
will use reasonable efforts to correct errors, if any, which are discovered
within the Warranty Period which either are present at the time of delivery of
the Software or are caused by warranty corrections performed by QUALCOMM and
which inhibit the Software's performance such that it does not perform
substantially in accordance with the specifications contained in the applicable
Software manual. The preceding remedies are available to Customer only if (i)
QUALCOMM is notified, in writing, by Customer of any defect within fifteen (15)
days after Customer's discovery of the defect, (ii) Customer's notification
shall contain a detailed description, in writing, of any malfunction of the
Software, including the frequency of the malfunction and the conditions
surrounding the malfunction, (iii) QUALCOMM from its examination can repeat the
error or malfunction to disclose that such defect actually exists, and (iv) the
Software has not been subjected to misapplication, misuse, damage, negligence or
accident. Any use of or modifications made to software not supplied by QUALCOMM
but which interface with the Software and which impair the functionality of the
Software shall be undertaken at Customer's sole risk. Customer acknowledges that
QUALCOMM's ability to provide the Software Warranty requires Customer's full
cooperation, including sample and/or diagnostic output and reasonable access to
the Authorized Equipment and may require down-time of the Authorized Equipment.
QUALCOMM's Software Warranty obligation is limited to the above remedy and
QUALCOMM makes no warranty that operation of the Software will be uninterrupted
or error free or that any errors discovered can be corrected.

2.6. SOFTWARE MAINTENANCE. During the Software Warranty Period, Customer will
also receive maintenance for the Software ("Software Maintenance") at no
additional cost consisting of: (i) upgrades and enhancements when such upgrades
and enhancements are developed by QUALCOMM and made generally available without
cost to other licensees of the Software, (ii) Software telephone support to
assist Customer's designated technical representative(s) in answering routine
questions with respect to the use of the Software, (iii) maintenance for
deviations between the Software and the documentation furnished by QUALCOMM, as
determined by QUALCOMM, and (iv) applicable Software documentation updates. Any
upgrades or enhancements developed or published by QUALCOMM which are not made
generally available at no additional cost to other licensees will be offered to
Customer at QUALCOMM's then current published rates. Determination of whether an
upgrade or enhancement will be made available at no additional cost or will be
made available only for an additional cost is the sole and exclusive right of
QUALCOMM. Upgrades and enhancements will be shipped to Customer in a mutually
acceptable media. QUALCOMM will install upgrades and enhancements only upon
request, with installation on a time and materials basis at QUALCOMM's then
current rates plus reimbursement for travel and per diem expenses. If QUALCOMM
fails to fulfill its Software Maintenance obligations as set forth herein,
Customer's sole and exclusive remedy is the right to terminate Software
Maintenance immediately. 

2.7. EXTENDED SOFTWARE MAINTENANCE. After the expiration of the
Software Warranty for the Software, Customer may obtain continued Software
Maintenance ("Extended Software Maintenance") by paying QUALCOMM's then current
annual Extended Software Maintenance fee for each Software product licensed
under this Agreement calculated at fifteen (15%) of the then list price for the
licensed Software product (the "Annual Maintenance Fee"). After the expiration
of the Software Warranty Period, Customer may elect to obtain QUALCOMM's
Extended Software Maintenance by paying the first Annual Maintenance Fee.
QUALCOMM will invoice Customer for the first Annual Maintenance Fee one (1)
month prior to expiration of the Software Warranty Period. Thereafter, the
Annual Maintenance Fee shall be due and payable annually within thirty (30)
days after the anniversary of the expiration of the Software Warranty Period.
QUALCOMM reserves the absolute right to terminate the Extended Software
Maintenance without prior notification to Customer in the event that Customer
has not paid the applicable charges in accordance with this Section. QUALCOMM's
Extended Software Maintenance shall be limited to support to the current
version and the immediately previously released version of the Software. If
QUALCOMM fails to fulfill its Extended Software Maintenance obligations as set
forth herein, the Customer's sole and exclusive remedy is the right to
terminate the Extended Software Maintenance immediately for the Software and
QUALCOMM shall refund to Customer any prepaid fees, prorated based upon a
thirty (30) day month, beginning from the effective date of such termination.

2.8. SUPPORT MODEM AND REMOTE ACCESS. QUALCOMM may as a condition to providing
Software Maintenance and Extended Software Maintenance hereunder, require
Customer to dedicate a communication port off of Customer's computer and supply
a dedicated phone line for use with a modem supplied by Customer meeting
QUALCOMM's specifications, for QUALCOMM's remote access use in support of the
Software. Customer will provide QUALCOMM with a user account and password to
access the Software on a 24 hour basis as an on-line end-user (with file
transfer capability), within a reasonable time after Customer has made a request
for support or as mutually agreed upon for installation of an upgrade or
enhancement. QUALCOMM will only access the account for purposes of (i) support
and maintenance of the Software, (ii) installations of upgrades, enhancements
and new version releases of the Software on mutually agreed upon schedules, and
(iii) or integration or other support agreed on between QUALCOMM and Customer.

2.9. OTHER SUPPORT. Except as provided in this Section 2, no software
maintenance, support or other services are provided under this Agreement. If
Customer requests and QUALCOMM elects to make corrections for difficulties or
defects traceable to Customer's errors or those of a third party, or to provide
support for system changes, upgrades, modifications, merges or improvements,
interfaces, operating systems, hardware configuration, data management, or other
system administration issues, Customer shall pay for QUALCOMM's services on a
time and materials basis at QUALCOMM's then current rates plus reimbursement for
travel and per diem expenses.

2.10. RETURN OF THE SOFTWARE. Upon any termination or expiration of this
Agreement, Customer shall, within ten (10) days of such termination or
expiration, return to QUALCOMM at Customer's expense all copies of the Software
and supporting documentation or, at QUALCOMM's discretion, provide written
certification that Customer has destroyed all copies of the Software including
any documentation.

3.   OMNITRACS SERVICE.

3.1. OMNITRACS SERVICE. The OmniTRACS Service (the "Service") consists of a
two-way Ku-band, satellite-based, mobile messaging and position 




                                       5
<PAGE>   6


location reporting service using various components of the OmniTRACS System
which is provided to Customer hereunder for installation and use only on
Customer's vehicles or independent contractors' vehicles contracting with
Customer.

3.2. CUSTOMER SERVICE. Customer shall immediately notify QUALCOMM of any
interruption in the Service. The QUALCOMM CUSTOMER SERVICE CENTER AT
(800)-541-7490 shall be contacted whenever there is a Service operation or
Equipment failure, Software problem, or other service/information is required.

3.3. ACTIVATION OF THE SERVICE; PRICE INCREASES. During the Term of the
Agreement the Service for each MCT is considered to be activated in Customer's
message service account upon the earlier of the date on which Customer requests
QUALCOMM to activate the Service for the MCT or thirty (30) days after the date
of shipment of the MCT. At the time of activation, Services and the associated
service rates and/or fees shall commence for all activated MCTs. The message
service rates set forth on Page 1 are subject to annual increases based upon
increases in the Bureau of Labor Statistics Consumer Price Index, Subgroup
"Urban Consumers (Revised)" as published by the U.S. Department of Labor for the
Los Angeles-Long Beach-Anaheim Metropolitan Area (1967 = 100 Base). Increases
shall be calculated no more than once per calendar year and shall be limited to
the difference between the index rate at the beginning of the calendar year and
the index rate at the end of the calendar year.

3.4. INTERNATIONAL USE. QUALCOMM has not yet received permission to transmit or
operate the Service in Mexico, and therefore, Customer is not authorized to use
the Service in Mexico. QUALCOMM has received interim approval which permits
QUALCOMM's customers to operate the Service in Canada while their trucks are
temporarily located in Canada (hereinafter "Interim Approval"). Customer
acknowledges that the Canadian Government has the authority to rescind the
Interim Approval. In the event the Canadian Government rescinds the Interim
Approval, QUALCOMM shall immediately notify Customer of such rescission and
Customer shall cease operating the Service in Canada until Customer is notified
by QUALCOMM that approval has been reinstituted.

3.5. UNAUTHORIZED USE OF THE SERVICE. Customer shall not use, or attempt to use,
the Equipment or Services for any Unauthorized Purpose or in such a manner as to
interfere with use by other customers of the OmniTRACS System. "Unauthorized
Purpose" as used herein includes: (i) obtaining access to or use of Services
with intent to avoid payment, in whole or in part, of charges due under this
Agreement, (ii) access to, use of, alteration of, or destruction of the data
files, programs, procedures, or information of Customer or any other QUALCOMM
customer, (iii) use of the Equipment or Services with the intent to reverse
engineer or clone the OmniTRACS System, (iv) use of the Software in such a
manner to void the Software license provided in Section 2 or (v) use of the
Services or Software furnished pursuant to this Agreement for any purpose or in
any manner which, directly or indirectly, violates the law or aids any unlawful
act or undertaking. QUALCOMM may, without notice to Customer, and without
liability to QUALCOMM, discontinue the Service in response to a request from a
government agency, including but not limited to the FCC. For other QUALCOMM
actions to discontinue Service to prevent use for an Unauthorized Purpose,
QUALCOMM will use best efforts to provide Customer twelve (12) hours
notification prior to discontinuing the Service. QUALCOMM shall restore the
Service as soon as the Service can be provided without undue risk of use for an
Unauthorized Purpose. Customer shall not be credited message service charges for
Service interruptions resulting from QUALCOMM's actions under this Section.

3.6. DANGEROUS OPERATION. Customer acknowledges that the use of MCTs while the
vehicle is in motion is DANGEROUS. Accordingly, Customer shall instruct all of
its drivers NOT TO USE THE SERVICE WHEN THE VEHICLE IS IN MOTION. If, and only
if, the vehicle is being driven by a team, the non-driver may operate the MCT
while the vehicle is in motion, provided the non-driver ensures such operation
does not distract the driver.

3.7. WARRANTY. QUALCOMM warrants that it shall maintain the Service so as to
provide Service Availability at least 98% per month for all hours, except from
10 p.m. to 3 a.m., Pacific Time, when QUALCOMM generally performs maintenance
actions. As used herein, "Service Availability" shall mean provision of the
Service free from interruption or break and shall include, in addition to the
ability of QUALCOMM's Network Management Facility to receive Customer's outbound
messages, the ability to transmit messages from the NMF to the involved
satellite and then to a ground terminal, and the ability to receive at the
Network Management Facility an acknowledgment originating at the ground terminal
that the message has been received. This Service Availability is predicated upon
normal usage for MCTs in service in the U.S. and does not include interruption
of Service as a result of force majeure events. For purposes of this paragraph,
"force majeure events" shall include, without limitation, satellite transponder
failure, ground telecommunications failure, acts of God, natural disasters,
strikes, compliance with governmental laws, and other events which are beyond
the reasonable control of QUALCOMM. In any month in which QUALCOMM does not
provide at least 98% Service Availability, then, as Customer's sole and
exclusive remedy, Customer shall be entitled to receive upon request a credit
against Customer's Service account in an amount per initiated MCT equal to (a)
$15.00, if Service Availability is less than 98% but more than 95%, or (b)
$25.00, if Service Availability is 95% or less. In the event the Service
Availability is less than 85% in any month, Customer shall not be charged any
monthly message charges for such month. The foregoing shall be Customer's sole
and exclusive remedy for any breach of warranty by QUALCOMM in connection with
the Services.

3.8. POSITION POLLS DATA RETENTION. OmniTRACS position location data for MCTs
operating within the continental United States ("position polls data") will be
deleted by QUALCOMM within fourteen (14) days after receipt of acknowledgment of
delivery to Customer over its telecommunications link (the "fourteen day
period"). QUALCOMM will maintain position polls data during this fourteen day
period for service and maintenance purposes and will each day automatically
delete position polls data which has previously been stored for fourteen (14)
days. A limited Optional Position Polls Data Retention Service is available for
a fee, which will be quoted upon request.

3.9. GROUND TELECOMMUNICATIONS LINK. Customer shall be responsible for all
charges, nonrecurring and recurring, associated with the telephone ground
communications link between Customer's dispatch facility computer and QUALCOMM's
Network Management Facility in San Diego, California. Customer shall select
either a QUALCOMM-provided 800 Number Service or a leased line service. QUALCOMM
shall have no warranty obligations in connection with any telephone ground
communications link, other than to pass through to Customer any warranties
provided by the vendor or other provider thereof.

3.10. OTHER SUPPORT. Except as provided in this Section 3, no other messaging or
position location reporting services or support are provided under this
Agreement. If Customer requests and QUALCOMM elects to provide other messaging
or position location reporting research or other support services, Customer
shall pay for QUALCOMM's services on a time and materials basis at QUALCOMM's
then current rates, plus reimbursement for travel and per diem expenses, if
applicable.

4.   DISCLAIMERS, LIMITATION OF LIABILITY AND INDEMNIFICATION.

4.1. LIMITATION OF LIABILITY AND REMEDIES. QUALCOMM's entire liability and
Customer's exclusive remedies for any damages arising from the performance or
nonperformance of the Equipment, Software, Maintenance, Service or other
services provided under this Agreement, regardless of the form of action,
whether in contract, breach of warranty, indemnification, or tort, 



                                       6
<PAGE>   7


including negligence, strict liability, or otherwise, shall be: (i) for breach
of warranty for the installation of MCTs the remedy set forth in Section 1.3;
(ii) for breach of warranty for the Equipment or for maintenance obligations
relating to the Equipment, the remedies set forth in Section 1; (iii) for breach
of warranty for the Software or for the maintenance obligations for the Software
the remedies set forth in Section 2; (iv) for breach of warranty for the
Service, including any breach of warranty relating to telecommunications
equipment, the remedies set forth in Section 3; and (v) for claims other than as
set forth above, QUALCOMM's liability shall be limited to direct damages proven
in an amount not to exceed the total purchase price paid by Customer for the
Equipment purchased during the calendar year in which the claim arose.

THE ENTIRE LIABILITY OF QUALCOMM AND THE EXCLUSIVE REMEDY OF CUSTOMER FOR BREACH
OF WARRANTY SHALL BE THE REPLACEMENT OF THE SOFTWARE OR REPLACEMENT OF THE
EQUIPMENT WHICH DOES NOT MEET THE WARRANTIES SET FORTH IN SECTIONS 1 AND 2 OF
THIS AGREEMENT. Provided however, in the event that such remedy for breach of
warranty fails of its essential purpose, QUALCOMM shall then, as Customer's sole
and exclusive remedy, reimburse Customer for that part of the Software or
Equipment as to which Customer has a claim in an amount not to exceed the
license fees paid for the Software or the purchase price paid for the Equipment,
as to which Customer has a claim, depreciated on a five (5) year straight line
basis from the date of shipment of the Software or the Equipment.


IN NO EVENT SHALL QUALCOMM NOR ITS SATELLITE SERVICE PROVIDER BE LIABLE TO
CUSTOMER FOR ANY INDIRECT, INCIDENTAL, CONSEQUENTIAL OR SPECIAL DAMAGES,
INCLUDING BUT NOT LIMITED TO ANY LOST PROFITS, LOST SAVINGS OR OTHER INCIDENTAL
DAMAGES ARISING OUT OF THE USE OR INABILITY TO USE THE EQUIPMENT, THE SOFTWARE,
OR THE SERVICE PROVIDED HEREUNDER, EVEN IF QUALCOMM OR ITS SATELLITE SERVICE
PROVIDER, HAS BEEN ADVISED OF THE POSSIBILITY OF SUCH DAMAGES.


4.2. DISCLAIMER OF WARRANTIES. EXCEPT FOR THE WARRANTIES SPECIFICALLY SET FORTH
IN SECTION 1 FOR THE EQUIPMENT, SECTION 2 FOR THE SOFTWARE, AND SECTION 3 FOR
THE SERVICES, THE EQUIPMENT, SOFTWARE, SERVICES AND MAINTENANCE PROVIDED
HEREUNDER ARE PROVIDED "AS IS" AND THERE ARE NO OTHER WARRANTIES MADE BY
QUALCOMM, EXPRESS OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, ANY IMPLIED
WARRANTIES OF MERCHANTABILITY OR FITNESS FOR A PARTICULAR PURPOSE.

4.3. INDEMNIFICATION. Customer shall indemnify, defend and hold QUALCOMM
harmless against any and all losses, claims, damages or expenses (including
attorneys' fees) arising out of or related to: (i) any personal injury to or
death of any person or persons, any loss or damage of any property or any
interruption of services which are caused or claimed to have been caused
directly or indirectly from Customer's (including its employees or independent
contractors) negligent operation and/or related use or misuse of the OmniTRACS
System and Equipment including, without limitation, use of the Equipment by the
driver of a vehicle which is in motion; (ii) use of any Outdoor Unit Mounting
Bracket or other equipment not provided or approved for use with the Equipment
by QUALCOMM; (iii) any use of the OmniTRACS System by Customer for an
Unauthorized Purpose; (iv) data or other information transmitted over the
OmniTRACS System, excluding any database provided by QUALCOMM; or (v) any breach
by Customer of any of the terms and conditions of this Agreement.

5.   INVOICING AND PAYMENT.

5.1. INVOICING. Deliverable Equipment and Software will be invoiced upon
shipment. The Base Connection Fee or Base Message Service Fee, as applicable,
and the Extended Maintenance Service Fee will be invoiced, in advance, on a
monthly cycle. All other Message Service, Extended Software Maintenance,
Installation, Communication Link and other service charges will be invoiced as
of the end of the monthly cycle in which they are incurred.

5.2. PAYMENT. Customer shall pay all invoices issued within thirty (30) days
from the date of invoice. QUALCOMM reserves the right to change the credit terms
at any time, when, in QUALCOMM's opinion, Customer's financial condition or
previous payment record so warrants. Should Customer become delinquent in the
payment of any sum due, QUALCOMM, after ten (10) days from the date of written
notice to Customer, shall not be obligated to continue performance under this
Agreement or any other agreement between QUALCOMM and Customer. A late charge of
the lesser of 1.5% per month or the maximum amount permitted by law, will be
added to past due accounts. All reasonable costs and expenses, including but not
limited to attorneys' fees, court costs and service charges incurred by QUALCOMM
in collecting payment will be an expense of and charge to Customer. Customer
waives any existing and future claims and offsets against payments due
hereunder, and agrees to pay the amounts due.

5.3. SECURITY INTEREST. Customer hereby grants and QUALCOMM reserves a purchase
money security interest in each item of Equipment purchased hereunder, and in
any proceeds therefrom, for the amount of its purchase price. Upon request by
QUALCOMM, Customer shall sign any document QUALCOMM deems is necessary to
perfect such security interest. Payment in full of the purchase price of any
item of Equipment purchased hereunder shall release the security interest in
that item of Equipment. If Customer fails to make any payment to third parties
or do any act as provided for in this Agreement, QUALCOMM shall have the right,
but not the obligation, without notice to or demand on Customer, and without
releasing Customer from any obligation hereunder, to make or do the same, and to
pay, purchase, contest or compromise any encumbrance, charge, or lien which in
the judgment of QUALCOMM appears to affect any Equipment in Customer's
possession which is owned by QUALCOMM or in which QUALCOMM has a security
interest, and in exercising any such right, incur any liability and expend
whatever amounts in its discretion it may deem necessary therefor. All expenses
so incurred by QUALCOMM shall be without demand immediately due and payable by
Customer and any accounts past due shall be subject to the late charge described
in Section 5.2 above for each delinquent month or part thereof, until paid.

5.4. TAXES. All prices and rates for the Equipment, Software, Service,
Maintenance and other services provided for under this Agreement do not include
sales, use, excise or similar taxes assessed at any time. Excepting those taxes
imposed upon QUALCOMM's income and FCC license fees, all applicable taxes and/or
assessments (including but not limited to assessments imposed by the FCC) shall
be paid by Customer. In the event that QUALCOMM, at its sole discretion, pays
for any such items on behalf of Customer, QUALCOMM will invoice Customer such
amount and Customer shall reimburse QUALCOMM in accordance with Section 5.2.

6.   TERM AND TERMINATION.

6.1. TERM. The term of this Agreement shall commence upon the Effective Date and
shall continue in effect for a period of five (5) years (the "Term").
Thereafter, the Agreement shall be automatically extended on a year-to-year
basis (the "Extended Term") unless terminated by either party in writing on not
less than ninety (90) days prior written notice to the other party prior to the
applicable anniversary of the Effective Date, provided that QUALCOMM may, by
notice delivered to Customer at least ninety (90) days prior to each such
anniversary, condition such renewal upon Customer's agreement to upgrade all or
a portion of the Equipment included in the OmniTRACS System at QUALCOMM's
then-current prices applicable to such upgrades, Customer's acceptance of
QUALCOMM's then-current terms and conditions and inclusion 




                                       7
<PAGE>   8

of QUALCOMM's then-current pricing for the Service and Extended Maintenance.

6.2. TERMINATION. Without limiting other causes, the occurrence of any of the
following shall constitute a material default and breach of this Agreement and
shall allow the non-defaulting party to terminate this Agreement for cause after
the expiration of the applicable period of cure, if any: (i) Any failure by
Customer to pay all sums which it is obligated to pay hereunder within ten (10)
calendar days of written notice that such sum is due; (ii) Any unauthorized
disclosure or use regarding the Software or the Equipment shall permit QUALCOMM
to terminate immediately; (iii) The Agreement shall terminate automatically,
without notice, upon (a) the appointment of a receiver to take possession of all
or substantially all of Customer's assets, (b) a general assignment by Customer
for the benefit of its creditors, or (c) the institution of a bankruptcy or
other insolvency proceeding by or against Customer; (iv) Any material default by
either party of an obligation, covenant or condition hereunder, other than those
set forth above, which is not cured within thirty (30) calendar days after the
defaulting party receives written notice of such default; or (v) Any event which
would constitute a material default or breach of any agreement between Customer
and QUALCOMM or any third party for the lease of the Equipment. QUALCOMM's right
to terminate hereunder shall include the right to terminate the Service without
additional notice to Customer.

7.   OTHER TERMS.

7.1. CONFIDENTIALITY OF AGREEMENT AND INFORMATION. Customer agrees that any
information contained in any document, including but not limited to this
Agreement and the pricing contained herein, or obtained from examination of any
Equipment or Software furnished by QUALCOMM hereunder (whether or not marked
with a confidential or proprietary data legend) shall be deemed to be QUALCOMM's
confidential or proprietary data. Customer shall not, except as necessary for
the performance of this Agreement, duplicate, use or disclose to any third
person (including any company affiliated with Customer) any such confidential or
proprietary data, without the prior written approval of QUALCOMM, not to be
unreasonably withheld, except as to any such disclosures which are required by
law. Upon the termination or earlier cancellation of this Agreement, Customer
shall promptly return to QUALCOMM all confidential or proprietary data received.
If the parties have executed a separate Non-Disclosure Agreement for the
protection of confidential or proprietary data, the terms and conditions of such
Non-Disclosure Agreement shall take precedence over this Section.

7.2. CHOICE OF LAW AND FORUM. This Agreement shall be governed by and construed
under the laws of the State of California, without reference to its conflict of
laws provisions. All disputes arising hereunder shall be heard only by a court
of competent jurisdiction in the County of San Diego, State of California, and
Customer hereby submits to the jurisdiction of such courts for the purpose of
litigating such disputes.

7.3. ASSIGNABILITY. Neither this Agreement, nor any rights, duties or interest
herein, shall be assigned, transferred, distributed, sublicensed, subcontracted,
pledged, or hypothecated by Customer without QUALCOMM's prior written consent.
Any such attempted conveyance in violation of this Section shall be void and
shall constitute a material default entitling QUALCOMM to terminate this
Agreement.

7.4. SEVERABILITY. If any of the provisions of this Agreement is determined to
be invalid, illegal, or otherwise unenforceable, the validity, legality and
enforceability of the remaining provisions shall not in any way be affected or
impaired thereby; and the parties shall substitute for the affected provision an
enforceable provision which approximates the intent and economic effect of the
affected provision as closely as possible.

7.5. SURVIVABILITY. The following provisions of this Agreement shall survive any
expiration or complete termination of this Agreement: 1.5, 1.6, 1.9, 2.3 through
2.5 inclusive, 2.10, 3.5 through 3.7 inclusive, 4.1 through 4.3 inclusive, 5.3,
5.4, 7.1, 7.2, 7.7 and 7.8.

7.6. WAIVER OF BREACH. The waiver by any party of a breach of any of the
provisions of this Agreement shall not operate as a waiver of any subsequent
breach.

7.7. NOTICES. All notices must be in writing and shall be deemed given: (i) when
delivered personally; (ii) when delivered by facsimile machine if confirmation
of receipt is requested and obtained; (iii) five (5) days after having been
mailed registered or certified mail, return receipt requested, postage prepaid;
and (iv) one (1) day after having been mailed by overnight mail with a reliable

invoice address on Page 1 hereof and to QUALCOMM at 6455 Lusk Blvd., San Diego,
CA 92121-2779, Attn: OmniTRACS Contracts Administration.

7.8. ATTORNEYS' FEES. If any party or parties commences an action against any
party or parties arising out of or in connection with this Agreement, the
prevailing party or parties shall be entitled to recover from the losing party
or parties reasonable attorneys' fees and costs of suit.

7.9. FORCE MAJEURE. Neither party shall be liable to the other for failure or
delay in the performance of a required obligation other than the payment of
money if such failure or delay is caused by riot, fire, flood, natural disaster,
act of God, governmental action or decree, or other event beyond such party's
control, provided that such party gives prompt written notice of such condition
and resumes its performance as soon as possible, and provided further that the
other party may terminate this Agreement if such condition continues for a
period of one hundred and eighty (180) days without demonstration by the
non-performing party of the ability to resume performance of its obligations
within a reasonable period.

7.10. REMEDIES. Due to the unique, confidential and proprietary nature of the
Software, Customer understands and agrees that QUALCOMM's remedies at law for
Customer's breach of this Agreement may be inadequate and that QUALCOMM shall be
entitled to equitable relief, including without limitation, injunctive relief,
specific performance or other equitable remedies in addition to all other
remedies provided herein or available to QUALCOMM at law or equity. No remedy
made available to QUALCOMM by any of the provisions of this Agreement is
intended to be exclusive of any other remedy, and each and every remedy shall be
cumulative and shall be in addition to every other remedy given hereunder or now
or hereafter existing at law or in equity or otherwise.

7.11. QUALCOMM LEASE. In the event Customer enters into a separate lease
agreement with QUALCOMM to lease all or a portion of the Equipment from
QUALCOMM, notwithstanding any provision to the contrary contained in this
Agreement, title to such leased Equipment shall remain vested at all times in
QUALCOMM or its assignees, any reference to Customer's purchase of or obligation
to pay the purchase price for the leased Equipment shall have no force and
effect, and payment for the Equipment shall be as set forth in the separate
lease agreement between QUALCOMM and Customer.

7.12. ENTIRE AGREEMENT. This Agreement contains the entire understanding,
agreements and representations of the parties, and Customer acknowledges and
agrees that in entering into this Agreement, Customer did not rely upon any
representations or warranties other than those set forth herein. This Agreement
supersedes all prior writings, discussions and understandings concerning the
subject matter. Any additional or different terms or conditions proposed by
Customer or contained in any purchase order are hereby rejected and shall be of
no force and effect unless expressly agreed to in writing by QUALCOMM. In order
to be binding, any waiver, alteration, amendment or modification of any of the
provisions of this Agreement must be in writing and signed by a duly authorized
representative of both parties.

parties may sign and deliver this Agreement by facsimile transmission. Each
party agrees that the delivery of the Agreement by facsimile shall have the same
force and effect as delivery of original signatures and that each party may use
such facsimile signatures as evidence of the execution and delivery of the

         TOTAL IMCTs/MCTs                               1,000 Units
</TABLE>

Deliveries may be made incrementally throughout the month until the total
monthly quantity is received. QUALCOMM's obligation to deliver the Equipment is
contingent upon QUALCOMM credit approval and, if applicable, receipt by QUALCOMM
of written confirmation of financing approval for the purchase of the Equipment.
Delivery dates are defined to be the date QUALCOMM ships the Equipment. All
deliveries shall be made to the Shipping Address first specified in this
Agreement unless otherwise specified by Customer within thirty (30) days prior
to the scheduled delivery date.

For the IMCTs/MCTs for which delivery is to be determined, Customer shall give
QUALCOMM sixty (60) days prior written notice of the desired delivery date(s)
and quantities of such IMCTs/MCTs to be delivered to Customer. QUALCOMM will use
its reasonable efforts to meet the delivery date requested by Customer, and will
notify Customer if a different delivery date is required.

For other Equipment and Optional Services purchased under this Agreement,
corresponding delivery schedules shall be specified upon mutual agreement.

                               SPECIAL PROVISIONS

I.       SUPERSEDING AGREEMENT.

         This Agreement supersedes in its entirety that certain OmniTRACS
Contract dated as of February 1, 1990 between Customer and QUALCOMM, as amended
from time-to-time, which shall be terminated as of the Effective Date of this
Agreement. The Customer Message Service Account currently in place for Customer
shall remain in effect under this Agreement.

II.      INTEGRATED MOBILE COMMUNICATIONS TERMINAL.

         A. IMCT Definition. QUALCOMM has developed an Integrated Mobile
Communications Terminal ("IMCT") which consists of two (2) components, the
Antenna Communication Unit ("ACU") and the standard Display Unit or Enhanced
Display Unit. The ACU combines the functionality and components of the current
MCT Communication Unit and the Outdoor Unit into one unit which closely
resembles the current Outdoor Unit in size and appearance. The ACU is installed
on the outside of the vehicle using the same type of Outdoor Unit Mounting
Bracket as used to install the Outdoor Unit with the exception that only two (2)
cables will be required in connection with the installation; a 36' power cable
and 4' display cable. Customer acknowledges that the cabling used to pre-wire a
vehicle for an MCT is not the same as the cabling required for the IMCT. Other
functional differences between the IMCT and the MCT are that the IMCT (i) will
only support SensorTRACS on vehicles with the J1708 datalink which has been
implemented as standard with all heavy duty truck manufacturers since
approximately 1990; and (ii) the IMCT has two (2) serial ports as opposed to the
four (4) serial ports currently provided with the MCT. The two (2) serial ports
available on the IMCT are configurable to support any two (2) of the following

</TABLE>

    C.  Examples of Incremental Charges Using the Volume Message Rates.

    i.  Message Activity for IMCT/MCT Fleet Average of 270 Messages and 27,000 
Characters.

For example, assuming a fleet average of 270 messages and 27,000 characters of
the IMCTs/MCTs activated in Customer's Message Service Account, since the
average messages and characters would be greater than the Base Message Service
(180 fleet average messages and 18,000 fleet average characters) by 90 messages
and 9,000 characters, the Incremental Charges per IMCT/MCT for the month would
be calculated at 30 messages and 3000 characters at the Volume 1 level (30
messages x $.05/message = $1.50 and 3000 characters x $.001/character = $3.00),
30 messages and 3,000 characters at the Volume 2 level (30 messages x
$.03/message = $0.90 and 3000 characters x $.0007/character = $2.10), and 30
messages and 3000 characters at the Volume 3 level (30 messages x $.03/message =
$0.90 and 3,000 characters x $.0006/character = $1.80) for total Incremental
Charges per IMCT/MCT of $10.20.

         Assuming a total fleet size of 1,000 IMCTs/MCTs activated in Customer's
Message Service Account, the total Incremental Charges would be $10,200.00
(1,000 x $10.20) in addition to the $50,000.00 for Base Message Service ($50 x
1,000) plus any charges for Excluded Messages.

         ii.   Message Activity for IMCT/MCT Fleet Average of 330 Messages and
33,000 Characters.



                                       15
<PAGE>   18

For example, assuming a fleet average of 330 messages and 33,000 characters of
the IMCTs/MCTs activated in Customer's Message Service Account, since the
average messages and characters would be greater than the Base Message Service
(180 fleet average messages and 18,000 fleet average characters) by 150 messages
and 15,000 characters, the Incremental Charges per IMCT/MCT for the month would
be calculated at 30 messages and 3000 characters at the Volume 1 level (30
messages x $.05/message = $1.50 and 3000 characters x $.001/character = $3.00),
30 messages and 3,000 characters at the Volume 2 level (30 messages x
$.03/message = $0.90 and 3000 characters x $.0007/character = $2.10), 30
messages and 3000 characters at the Volume 3 level (30 messages x $.03/message =
$0.90 and 3,000 characters x $.0006/character = $1.80), 30 messages and 3000
characters at the Volume 4 level (30 messages x $.02/message = $0.60 and 3000
characters x $.0006/character = $1.80), 30 messages and 3000 characters at the
Volume 5 level (30 messages x $.02/message = $0.60 and 3000 characters x
$.0005/character = $1.50) for total Incremental Charges per IMCT/MCT of $14.70.

         Assuming a total fleet size of 1,000 IMCTs/MCTs activated in Customer's
Message Service Account, the total Incremental Charges would be $14,700.00
(1,000 x $14.70) in addition to the $50,000.00 for Base Message Service ($50 x
1,000) plus any charges for Excluded Messages.

         D. Minimum Average Messages and Characters per Volume Message Rate 
Level. In the event that the average incremental character count exceeds that
which corresponds to the applicable volume message level, Customer shall be
invoiced for one (1) additional message per one hundred (100) incremental
characters at the rate for the next applicable volume character count level.

For example, referring to Example C(i), if the average number of messages is 270
(Level 3), and the average character count is 29,000 (Level 4), at Volume Level
3 there are 2000 incremental characters (29,000 - 27,000). These 2000
incremental characters will be invoiced at Level 4 rates (2,000 characters x
$.0006 = $1.20), in addition to 20 messages at Level 4 rates (2000 characters
divided by 100 characters per message) (20 x $.02 = $.40) for a total of $1.60
for the 2,000 incremental characters. Total Incremental Charges are $11.80
($10.20 + $1.60 = $11.80).

In the event that the average incremental message count exceeds that which
corresponds to the applicable volume character level, Customer shall be invoiced
for one hundred (100) characters per incremental message at the rate for the
next applicable volume message level.

For example, referring to Example C(i), if the average number of messages is 290
(Level 4), and the average character count is 27,000 (Level 3), at Volume Level
3 there are 20 incremental messages (290 - 270). These 20 incremental messages
will be invoiced at Volume 4 rates (20 messages x $.02 = $.40), in addition to
2000 characters at the Level 4 rates (20 messages x 100 characters per message)
(2000 x $.0006 = $1.20) for a total of $1.60 for the 20 incremental messages.
Total Incremental Charges are $11.80 ($10.20 + $1.60 = $11.80).

         E. "In-Service" IMCTs/MCTs. As used pursuant to this Agreement,
"in-service" means an activated IMCT/MCT which has sent or received a message
during the then applicable billing month in a Customer Message Service Account
using Base Message Service with fleet 



                                       16
<PAGE>   19

averaging. For each calendar month of the initial five (5) year Term of this
Agreement, QUALCOMM shall not charge Customer the Base Message Service charge
for activated IMCTs/MCTs which were not "in-service" during the previous month
(did not send or receive a message during the previous month) subject to a
maximum limitation of [DELETED] of the number of IMCTs/MCTs purchased by and
delivered to Customer from QUALCOMM as of the first day of such month.
IMCTs/MCTs which are not "in-service" and for which Base Message Service charges
are not paid, shall be excluded from the base number of IMCTs/MCTs for purposes
of calculating the fleet average IMCT/MCT messages and character counts for
determination of Incremental charges.

         F. Volume Discount on Message Service Charges. QUALCOMM shall also give
Customer a one tenth (1/10) percent volume discount on Base Message Service
charges and Incremental Charges each month for each 100 IMCTs/MCTs that were
purchased by and delivered to Customer from QUALCOMM, and has activated in its
Message Service Account, up to a total volume discount of 5%. For example, using
example (i) in subparagraph (C) above, if Customer has 1,000 IMCTs/MCTs
activated, Customer's total Base Message Service and Incremental Charges of
$60,200.00 or $60.20 per IMCT/MCT would be reduced by one percent (1%) for a
reduced total Base Message Service and Incremental Charges of $602.00 which is
approximately $.60 per IMCT/MCT.

         At 627 IMCTs/MCTs delivered to Customer as of January 10, 1997,
Customer's volume discount may be up to .6%. QUALCOMM will add an additional
discount of .1% for each one hundred (100) additional IMCTs/MCTs purchased by
and delivered to Customer which are activated. For example, at 1,000 IMCTs/MCTs
activated, Customer will receive a discount of 1%, at 1,500 IMCTs/MCTs activated
Customer will receive a discount of 1.5% and so on up to a total cap of a 5%
volume discount at 5000 total purchased IMCTs/MCTs activated in Customer's
Message Service Account.

         G. [DELETED]

         H. Off-Hours Discount. Customer shall receive an off-hours discount
equal to a forty percent (40%) reduction in the calculation of the number of
messages and characters sent by Customer during the hours of 9:00 p.m. to 3:00
a.m., Pacific Time, Monday through Friday, and all hours Saturday and Sunday
(the "Off Hours"). For example, (i) if a total of 50 messages were sent during
Off-Hours, when calculating the number of messages per IMCT/MCT sent for
purposes of invoicing Customer, QUALCOMM would reduce the 50 messages by
20, resulting in a calculation of 30 messages; and (ii) if a total of 5000
characters were sent during Off- Hours, when calculating the number of
characters per IMCT/MCT sent for purposes of invoicing Customer, QUALCOMM would
reduce the 5000 characters by 2000 characters, resulting in a calculation of
3000 characters. The Off-Hours discount shall be calculated and applied prior to
the calculation of Incremental Charges as set forth in Sub-paragraph VI.B.,
above.

VII.     QTRACS/400 SOFTWARE.

         A. License. QUALCOMM agrees to continue to license to Customer, the
QTRACS/400 Software with External Application Link Software modules
(collectively referred



                                       17
<PAGE>   20

to herein as the "Software") currently in Customer's possession and for use
solely in conjunction with the OmniTRACS System. The QTRACS/400 Software enables
the dispatcher or other user to interface with the OmniTRACS System to provide
two-way messaging and position history reporting and other IMCT/MCT functions,
and provides for the interface between an IBM AS/400 computer system supplied by
Customer and QUALCOMM's Network Management Facility. The External Application
Link Software modules provide for the interface of the QTRACS/400 Software to
Customer's dispatch software. The warranty for the Software is twelve (12)
months from the Effective Date of this Agreement, and as set forth in Section
2.5, entitled "Software Warranty." The provisions of this Agreement, including
but not limited to Section 2 entitled, "OmniTRACS Software" shall govern the
license granted to Customer to use the Software.

         B. QTRACS/400 Software Maintenance.  After expiration of the warranty, 
Customer may obtain extended software maintenance for the QTRACS/400 Software in
accordance with Section 2.7. entitled, "Extended Software Maintenance."

VIII.    TELECOMMUNICATIONS LINK.

         In accordance with Section 3.9, entitled "Ground Telecommunications
Links," QUALCOMM will continue to provide Customer a digital leased line
communications link in place at the current monthly recurring rate which is
subject to adjustment as QUALCOMM's telecommunications provider adjusts its
monthly fee.

IX.      ENHANCED DISPLAY UNITS.

         A. EDU Definition. The Enhanced Display Unit ("EDU") may be used as a
replacement for QUALCOMM's standard Display Unit which integrates with the
OmniTRACS Communication Unit of the MCT or the ACU of the IMCT. The elements of
the EDU are: (1) a graphics display with 15 lines of text, and (2) a QWERTY
keyboard and numeric keypad with backlit keys.

         B. EDU Pricing.  Customer may elect to purchase the EDU from QUALCOMM
for the purchase prices set forth below:

            i.  If Customer orders the EDU as a component of a new
IMCT/MCT, the purchase price per EDU shall be $200.00 in addition to the
purchase price of $[DELETED] for the IMCT/MCT, for a total IMCT/MCT purchase
price of $[DELETED]. For orders of IMCTs/MCTs with EDUs, QUALCOMM will deliver
the IMCT/MCT without the standard Display Unit component. Prior to shipment of
each IMCT/MCT, Customer shall designate the shipping address and whether or not
each IMCT/MCT is to include the EDU in place of the Display Unit. If Customer
does not specify whether the ordered IMCTs/MCTs are to include Display Units or
EDUs, QUALCOMM will ship such IMCTs/MCTs EDUs.
               

            ii. If Customer orders the EDU as a replacement to a Display Unit 
for a previously purchased IMCT/MCT equipped with a Display Unit, the purchase
price per EDU shall be $400.00, which includes the EDU holster.

<PAGE>   22

consists of (i) the IMCT/MCT firmware which when connected using a 37 Pin
Accessory Cable monitors specified vehicle sensors or inputs ("the SensorTRACS
Feature"), and (ii) the application software which resides on Customer's
dispatch computer which allows for data transmission from the IMCT/MCT to the
dispatch computer using the OmniTRACS System (the "SensorTRACS Application
Software"). All OmniTRACS messages which occur in the use of the SensorTRACS
System, as described in the attached Exhibits "A." constitute regular messages
under the OmniTRACS Service and will be invoiced in accordance with the message
services described in Items 18 through 25, inclusive on Page 2 of the Agreement
and payable in accordance with Section_5.

     B. SensorTRACS Feature License and Enabling Fees. QUALCOMM will continue to
license the SensorTRACS Feature to Customer. As of the Effective Date of this
Agreement, for all new orders of IMCTs/MCTs, QUALCOMM will invoice Customer the
license and enabling fee of $250.00 per IMCT/MCT for the SensorTRACS Feature in
accordance with Section 5. The SensorTRACS license and enabling fees invoiced
for all MCTs delivered to Customer prior to January 1, 1997 are not subject to
rebate. For future orders of IMCTs/MCTs, Customer shall specify at the time of
an order whether Customer desires to include the SensorTRACS Feature. In the
event Customer elects to obtain the SensorTRACS Feature, QUALCOMM will invoice
such amount upon shipment of each IMCT/MCT in addition to the IMCT/MCT Purchase
Price. For Customer to use the SensorTRACS Feature, a 37 Pin Accessory Cable is
required for each IMCT/MCT. QUALCOMM shall provide one (1) 37 Pin Accessory
Cable per IMCT/MCT at no charge. All additional orders of 37 Pin Accessory
Cables will be at the price set forth in Attachment 1, Spares Price List. The
SensorTRACS license and enabling fee per IMCT/MCT does not include SensorTRACS
installation labor including sensor calibration, or dual signal multipliers, if
needed. QUALCOMM will install the SensorTRACS Feature and the 37 Pin Accessory
Cable for no additional charge if the SensorTRACS installation is done
concurrently with a QUALCOMM IMCT/MCT installation. Customer's license to use
the SensorTRACS Feature granted in this Paragraph are subject, but not limited
to Section 2.1 entitled, "Software License." QUALCOMM will invoice and Customer
agrees to pay the invoiced amount described above in accordance with Section 5.

     C. SensorTRACS Application Software License Fees. Application Software is
required for the operation of the SensorTRACS Systems. QUALCOMM will continue to
grant Customer a license to use the application software, currently in
Customer's possession, which will support SensorTRACS on Customer's AS/400
computer system (the "SensorTRACS/400 Software"). Customer's license to use the
SensorTRACS/400 Software shall be subject to the terms of the Agreement,
including, but not limited to, Section 2.

     D. Application Software Maintenance. The warranty for the SensorTRACS/400
Software is twelve (12) months from the Effective Date of this Agreement and as

                                   EXHIBIT "A"

                              SENSORTRACS(R) SYSTEM


     The SensorTRACS System is an optional product and service available on the
OmniTRACS(R) System which provides summarized operating data such as vehicle and
engine overspeed, and idle time accumulation. The SensorTRACS System consists of
the SensorTRACS firmware contained in the Communication Unit of the IMCT/MCT
(the "SensorTRACS Feature") and the SensorTRACS application software (the
"SensorTRACS Application Software") which resides on the Customer's dispatch
computer to utilize forward and return messages over the OmniTRACS System for
the transfer of data as more fully described below. As described herein, the
SensorTRACS Feature is limited to the functionality of IMCT/MCT version
11.09/11.10. Additions or changes to the functionality of the SensorTRACS
Feature in subsequent firmware versions may be subject to additional license and
enabling fees.

     The speed, RPM, and/or other data inputs are obtained by monitoring
existing vehicle sensors either directly or via a vehicle data link. The manner
in which the data is captured is affected by a set of user specified parameters
such as overspeed thresholds for both the vehicle and engine ("Parameters"). The
data is captured in up to five (5) separate driver accounts. A default account
is used whenever there is not a driver explicitly "logged on" to SensorTRACS,
and the other four (4) accounts are opened based on "log on" of drivers using
numeric identifiers entered at the IMCT/MCT keyboard/display. Identifying
numbers used to log on are not validated by the IMCT/MCT. Certain of the summary
statistics for each driver may be viewed on the IMCT/MCT display. Periodically
the data accumulated in one or more driver account in the IMCT/MCT is
transferred over the OmniTRACS System (an "Extract," with reset) to the dispatch
computer, and the account is reset to zero.

SensorTRACS data may only be received at the dispatch computer by using the
OmniTRACS System with SensorTRACS Application Software. Data transmission may be
initiated automatically by the IMCT/MCT under certain conditions, or as the
result of a request for an Extract from the dispatch computer using the
OmniTRACS System. Requests for Extracts and changes to Parameters (referenced
above) are sent to the vehicle using OmniTRACS forward messages. Extracts
settings are obtained using OmniTRACS return messages.
