   ITEM 1.  DESCRIPTION OF BUSINESS

   Introduction

   The Company has two main business units:

   1.       BOATRACS, Inc. ("BOATRACS") and
   2.       Enerdyne Technologies, Inc. ("ENERDYNE"), a wholly owned 
                    subsidiary.
   BOATRACS

   BOATRACS'  objectives  include  providing  reliable and cost  effective  data
   communications  systems for commercial marine  applications.  To achieve this
   objective,  BOATRACS currently offers several satellite-based  communications
   and  tracking  systems  (the  "Boatracs  System")  and  integrated   software
   solutions. In addition,  BOATRACS or its wholly owned subsidiaries,  BOATRACS
   (Europe) B.V. and  Oceantracs,  Ltd.,  offer  similar  services in Europe and
   Canada, respectively.

   BOATRACS'  customer base is the commercial  marine  industry,  which includes
   commercial  fishermen,  fuel  transporters  and the workboat  industry of the
   inland  waterways  and coastal  areas.  The  industry has  demanding  service
   requirements including mobility, positioning, durability, confidentiality and
   integrity of communications  signals for the management of information.  Such
   information  includes vessel logs, supplies,  wage information,  and fuel and
   engine monitoring.  The integration of this information  directly into office
   computer systems is very important to the Company's customers.  The Company's
   software  includes  tools for both the  vessel and the  office  enabling  the
   integration of this information. The Company also maintains a 24-hour network
   center providing  personal  message  relaying  services to its customers with
   fleets of vessels and to individual vessels.

   In order to meet  industry  demands,  in November  1997,  BOATRACS  purchased
   certain  assets of MED  Associates,  Inc.  ("BOATRACS  Gulfport")  as a going
   concern.  BOATRACS  Gulfport  is a  Mississippi  based  provider  of software
   applications and service  solutions to the commercial  maritime  industry and
   oil companies.

   ENERDYNE

   On July 7, 1998, the Company  acquired  ENERDYNE,  which was a privately held
   company located in Santee,  California.  ENERDYNE develops,  builds and sells
   digital video compression equipment for the aerospace,  military, intelligent
   transportation, government and commercial markets.

   ENERDYNE  was  formed in 1983 and  initially  focused on the  development  of
   proprietary  solutions and protocol  with the precision  necessary to provide
   motion joint  photographers  expert group  ("MJPEG")  based  real-time  video
   compression technology for the United States military.  ENERDYNE continues to
   develop innovative solutions delivering real-time compressed video for use in
   unique applications such as the downlink of multiple video signals from Space
   Shuttle  Columbia  flights,   video   transmission   solutions  for  remotely
   controlled  cranes,  tanks  and  personnel  carriers  and  unmanned  airborne
   vehicles ("UAV").  ENERDYNE products have broad  applications for other video
   surveillance  markets.  ENERDYNE  has had  success  providing  solutions  for
   applications in intelligent  transportation systems (ITS) and has developed a
   reputation for its traffic surveillance products.

   ENERDYNE's  proprietary technology is based on digitizing the real-time video
   from the  camera  and  transfer  of the signal  using its  patented  protocol
   between its encoder and decoder  hardware which is built in its own facility.
   In its basic form the encoder  takes an analog  signal  from a video  source,
   digitizes it, and then compresses it for  transmission.  ENERDYNE's  products
   use several  compression  methods including Joint Photographic  Experts Group
   ("JPEG").

   The  advantages of digital data with video is that it is easily  multiplexed,
   can be encrypted and transmitted over many digital mediums.  The transmission
   quality  is not  affected  by the  number of  repeaters.  Compression  of the
   digital video allows a lower bandwidth utilization and therefore,  can reduce
   costs.

   The Company derives revenue primarily from four sources:

         BOATRACS:
         1. Sales of satellite based communications equipment and software
            and  additional,   complementary   and/or  modified  equipment
            created or procured by the Company for maritime application.
         2. Data transmission and messaging charges.
         3. Software  license fees and charges for custom  software  development
         solutions. 
         ENERDYNE:
         4. Development  and sales of video  compression
         products.

   Background

   The  Company  was  incorporated  in  California  in 1982 under the name First
   National  Corporation  as a bank  holding  company.  From  1982 to 1993,  the
   Company  provided,  through  its  wholly  owned  subsidiaries,  business  and
   individual banking services and certain corporate trust services.

   On November 9, 1993, First National  Corporation  filed a voluntary  petition
   under  Chapter 11 of the United States  Bankruptcy  Code in the United States
   Bankruptcy  Court for the Southern  District of California  (the  "Bankruptcy
   Court").

   On January 12, 1995, the Company (formerly First National Corporation) merged
   with BOATRACS, Inc. ("Old BOATRACS"), a California corporation formed in 1990
   to be a  distributor  in the United  States  marine  market of the  OmniTRACS
   satellite-based  communications and tracking system  manufactured by QUALCOMM
   (the  "Merger").  The Merger was  approved  by the  Bankruptcy  Court.  First
   National  Corporation had no significant  assets at the effective date of the
   Merger.

   Pursuant to the Merger,  the Company,  which was the  surviving  corporation,
   changed its corporate name to "BOATRACS, Inc."; the outstanding shares of Old
   BOATRACS were converted  into the right to receive  slightly less than 95% of
   the shares of common  stock to be issued by the  surviving  corporation;  and
   each of the  outstanding  shares of First National  Corporation was converted
   into the  right  to  receive  1/7 of one  share  of the  common  stock of the
   surviving  corporation,  with an  aggregate  of slightly  more than 5% of the
   shares of common stock issued by the Company to be issued to the shareholders
   of First National Corporation prior to the Merger. As a result of the Merger,
   the 63,018 issued and outstanding  shares of Old BOATRACS were converted into
   the right to receive  9,500,000 shares of the Company's common stock, and the
   3,570,899 issued and outstanding shares of the common stock of First National
   Corporation  were converted into the right to receive  approximately  510,000
   shares of the Company's common stock. The Company became the successor to the
   business of Old BOATRACS.

   The BOATRACS Systems

   The  BOATRACS  System was  adapted  and  enhanced  by the  Company for marine
   application  predicated  on  the  OMNITRACS  System  developed  by  QUALCOMM,
   Incorporated.   The  BOATRACS  System  provides   confidential  two-way  data
   communications  between a vessel or vessels at sea and a base station on land
   through  the use of a mobile  communications  terminal  ("MCT"),  a satellite
   communications  system and data delivery  systems.  The BOATRACS  System also
   allows for hourly position reporting and monitoring and, using  supplementary
   products, can provide engine performance and fuel consumption monitoring.  As
   of December 31, 1998, the Company had installed approximately 1700 systems on
   marine vessels. The BOATRACS System is effective while a vessel is within the
   satellite's  "footprint,"  which  extends  approximately  200  to  400  miles
   offshore most areas of the  continental  United  States,  Canada and parts of
   Europe or world-wide if using other satellite providers.  The BOATRACS System
   is an interactive  communications  network linking a vessel to shore and from
   shore-based  personnel  to  vessels  and  from  boat to  boat in most  cases.
   Messaging and  positioning  information  are forwarded  from the vessel,  via
   Ku-band satellite, to the QUALCOMM Network Management Facility ("NMF") in San
   Diego,  California,  or  similar  facilities  in  Europe,  and then onto base
   stations at the customers' offices or to the Company's 24-hour network center
   ("BNC") also in San Diego.  Messages that go to the Company can be relayed by
   fax or e-mail,  or by an operator via phone or fax.  The  BOATRACS  System is
   capable of sending or receiving digital (text) messages or files to or from a
   vessel.  In San Diego,  the BNC is linked via a dedicated  telephone line for
   data  transfers  via modem  directly to  QUALCOMM's  NMF in San Diego,  where
   message  transmissions  to and from the vessels are formatted and  processed.
   The BNC also has a dedicated  line to a local internet  service  provider for
   internal internet use as well as value-added  messaging  services for vessels
   and other satellite providers.

   The BNC provides message relaying and stand-by backup services for fleets and
   individual vessels using the system in the United States,  Europe and Canada.
   Computers  communicate  to the  QUALCOMM  NMF by  modem to  monitor  customer
   accounts on the system.  Operators relay satellite  messages  between vessels
   and their  families  or  business  associates  on shore and from  shore-based
   personnel to vessels. Other custom services are also available.  The BNC also
   provides  enhanced  communication  services to the  customers,  including the
   relay  of  E-mail  messaging,  broadcast  of  weather,  distribution  of data
   relating to customer's positioning and emergency back-up services.

   The Company  charges its customers for the  transmission  of each message and
   for the  transmission  of each  character  within a message.  There is also a
   monthly  connection  fee for the MCT to be on-line  and for  hourly  position
   reports.  The  charges are subject to certain  volume  discounts.  Additional
   charges are assessed for certain services provided by the network centers.

   On the Vessel

   The MCT consists of three basic  components:  the  Communications  Unit,  the
   Keyboard/Display  Unit  and  the  Outdoor  Unit  and  sells  in  a  range  of
   approximately  $5,000 to $6,000  dependent on features and volume  discounts.
   The design of the unit allows for both ease of installation and efficient use
   of normally space.  Software menus and simple wording on the Keyboard/Display
   Unit facilitate easy use of the system to send and receive messages. Although
   many of the  Company's  customers use only the basic MCT,  optional  products
   that interface with the basic unit are also offered.  Customers also have the
   option  of using  personal  computer  and  BOATRACS'  WINDOWS  BOATCOMM  User
   Interface  Software ("WBUI") instead of the  Keyboard/Display  Unit. The WBUI
   allows for the same  features  as the  Keyboard  Display  Unit with the added
   benefits of using a full screen and being able to send/receive computer files
   of any type.

   Many of the Company's customers also use marine application software programs
   developed by BOATRACS' Gulfport division.  Such application  software enables
   onboard users to enter  business  information  into forms that are saved to a
   local database and are transmitted to the shore station as files.

   In the Office

   Generally, a customer with less than four units only uses the BNC. Typically,
   a customer who has more than four  BOATRACS  System units elects to establish
   an in-house  base  station.  The base station  provides the customer  with an
   in-house communications link and vessel-tracking capability. The base station
   is  comprised  of  a  computer  and  either  the  Company's  or  third  party
   communications  software containing a mapping function enabling a customer to
   follow the progress of its fleet on a detailed  computer map.  Communications
   are conducted via modem directly  between the customer's base station and the
   NMF  maintained  by QUALCOMM for  satellite  transmission  to the  customer's
   vessels. Some customers also have custom marine application  software,  which
   was  developed by BOATRACS'  Gulfport  division.  This  application  software
   stores  data  files  received  from  the  vessels  and  enables   management,
   dispatchers,  and others to retrieve reports to manage their fleet of vessels
   and to provide data to their customers.

   Based upon  reports  from  customers,  the Company  believes  that its marine
   industry customers typically experience increased worker productivity,  asset
   utilization and dispatching  efficiency  while saving  communications  costs.
   Many  customers  enter into a three to five-year  contract  with the Company,
   establishing  a fixed  rate to be paid  for  messaging  services  used by the
   customer during the contract term.

   BOATRACS  Gulfport Division

   Effective  November 1, 1997,  the  Company  purchased  certain  assets of the
   BOATRACS  Gulfport  for  cash,  and  Common  Stock.  BOATRACS  Gulfport  is a
   developer of external  application  software  services to the marine industry
   for use in  connection  with the  BOATRACS  System  and  other  communication
   systems.  The external application software can enhance the customer's use of
   operational  data sent  through  the  BOATRACS  System.  Additionally,  their
   proximity to existing and future Company  customers in the work boat industry
   facilitates more timely customer service solutions to those customers.

   The  BOATRACS'   Gulfport   division   provides  custom  developed   software
   applications  to  offshore  and some  inland  boat and barge  companies.  The
   BOATRACS Gulfport  division's  services include systems design,  development,
   implementation,  training and onboard installation.  Their relationships with
   key large customers often lead to serial consulting  assignments  whereby one
   project leads to another.  Some customers  outsource a significant  amount of
   their  information  technology needs to the BOATRACS Gulfport  division.  The
   ability of the BOATRACS  Gulfport division to provide solutions for customers
   has enhanced the ability of the Company to sell MCTs to vessel operators.

   ENERDYNE

   The  Company  acquired  ENERDYNE  on July 7, 1998 by means of a merger into a
   wholly owned  subsidiary  of the Company.  ENERDYNE  sells video  compression
   equipment  for   aerospace,   military  and  commercial   applications.   The
   acquisition  was funded  through the issuance of the  Company's  common stock
   warrants, notes payable and the payment of cash.

   ENERDYNE  develops and builds video  products that enable the  realization of
   high performance  digital video compression  solutions.  ENERDYNE's  patented
   technology  provides  the  Company  with an unique  market  position in video
   encoders,  decoders and  multiplexing  equipment  used in airborne and ground
   based digital  video  systems.  Primary  markets for these  products  include
   Defense, Intelligent Transportation Systems,  Surveillance and Aerospace. The
   average  selling price of the ENERDYNE  products range from $1,950 to $23,500
   depending on the model and options selected.  A multiplexer  combining audio,
   data and alarms may be used in conjunction with some equipment.  ENERDYNE has
   focused,  and the Company will  continue to focus,  on  developing  very high
   quality products that have long life cycles and require minimal modification.

   ENERDYNE  designs,  develops and manufactures its products at its location in
   Santee, California.  Products range from rack mounted industrial equipment to
   miniaturized and ruggedized environmentally protected units. The products are
   designed to contain interfaces with data channels,  including wire, microwave
   and fiber optic. ENERDYNE's customers include various United States and state
   government agencies including the Navy, Air Force, Army and NASA,  Department
   of Transportation in various jurisdictions and the Department of Defense.

   Dependence upon Significant Customers

   A  material  source  of  the  BOATRACS   division   customers  for  its  core
   communications  business is the commercial  marine  industry.  Two customers,
   Tidewater   Inc.  and  Ingram  Barge   Company   represented   24%  and  10%,
   respectively, of the Company's total sales in 1998. The loss of either one of
   these customers could have a material adverse effect on the Company.

   For the period since the Company acquired ENERDYNE in July 1998, ENERDYNE has
   relied on two  customers:  L-3  Communications  Systems and The Naval Warfare
   Center which represented 19% and 16%, respectively, of ENERDYNE's revenues.

   The  major  customers  may  change  yearly  as they are  calculated  on total
   revenues  including  sales  of  communications  systems,  video  transmission
   products and other  products.  Purchases of  communication  systems and video
   transmission  products by a customer may not occur yearly and there can be no
   assurance that such customers will make significant  purchases of products in
   the future.  No relationship  exists between the Company and any of the above
   customers  except normal business  relationships.  In addition,  the BOATRACS
   Gulfport division provides software  solutions to communication  customers of
   the Company.

   Agreements

   Agreements with QUALCOMM

   The Company has exclusive distribution rights for the OmniTRACS System in the
   United States for marine  application  within  defined  coastal waters of the
   United  States  of the  Atlantic  and  Pacific  Oceans  under a  License  and
   Distribution Agreement dated June 13, 1990, as amended from time to time (the
   "Distribution  Agreement") with QUALCOMM.  The Distribution  Agreement had an
   initial  term of five years with three  options to extend for five years each
   (provided  that the  Company  is in full  compliance  with  the  terms of the
   Distribution  Agreement)  for a total of twenty years through 2010. The first
   option  to  extend  has  been  exercised  by the  Company.  The  Distribution
   Agreement calls for the negotiation in good faith of a new agreement upon the
   expiration of the last option.

   Under the Distribution Agreement, the Company has exclusive rights to provide
   messaging services to end users of such products for marine application.

   Under the Distribution  Agreement,  the Company is required to sell a certain
   minimum  number  of  MCTs  in  order  to  maintain  the  exclusivity  of  its
   distribution rights. The minimum purchase requirements for each calendar year
   are to be agreed upon between the Company and  QUALCOMM  subject to a minimum
   of 300 MCTs for the calendar year ending  December 31, 1997 and increasing by
   10% each year  thereafter.  The  minimum  sales were met for the years  ended
   December 31, 1998, 1997 and 1996.

   QUALCOMM is responsible for the manufacture and warranty repair of all of the
   OmniTRACS  units  supplied  by it  subject  to the terms of the  Distribution
   Agreement.  Warranties for a specified  period are passed on to the Company's
   customers. Extended warranties may be purchased at an additional cost.

   If the Company  desires to sell its core  maritime  communications  business,
   QUALCOMM has a right of first  refusal  under the  Distribution  Agreement to
   purchase  the  Company's  maritime  business  on the terms of the sale to the
   proposed transferee.

   QUALCOMM's   obligation  to  provide  messaging   services  pursuant  to  the
   Distribution  Agreement was contingent upon, among other things,  receiving a
   permanent  license  from the  Federal  Communication  Commission  ("FCC")  to
   operate the OmniTRACS System for marine application. This license was granted
   to QUALCOMM,  effective January 3, 1997, which added marine capability to use
   with the OmniTRACS  system for up to 100,000 MCTs for a term of 10 years.  In
   addition,  the  International  Telecommunications  Union ("ITU") approved the
   Ku-band  frequency  which  OmniTRACS  uses for  mobile use  including  marine
   applications.

   During March,  1995, the Company issued  1,112,265  shares of Common Stock to
   QUALCOMM  for  $737,000.  The  purchase  price  of the  shares  was paid by a
   reduction in the price of certain products and services currently provided by
   QUALCOMM to the Company and, upon  satisfaction  of certain  conditions,  the
   conversion  of a certain  non-exclusive  territory to an exclusive  territory
   under the License Agreement and the Distribution  Agreement.  The transaction
   was recorded as a note  receivable  for Common Stock issued which was reduced
   as discounts  are earned.  By June 30, 1998, a total of $737,000 in discounts
   had been earned reducing the note receivable balance to zero.

   Sub-Service Provider Agreement with ALCATEL QUALCOMM

   In March,  1997,  BOATRACS'  wholly-owned  subsidiary  BOATRACS (Europe) B.V.
   signed a five year Sub-Service  Provider  Agreement with ALCATEL QUALCOMM,  a
   French  company,  which is a joint venture  company between the ALCATEL Group
   and  QUALCOMM.  The  agreement  appoints  BOATRACS  (Europe)  B.V.  to be the
   maritime distributor and to provide maritime  satellite-based  communications
   and  tracking of vessels to certain  countries  in Europe on a similar  basis
   upon which the Company operates in the United States.

   Service Provider Agreement with Iceland Telecom

   In  July  1998,  BOATRACS  (Europe)  B.V.  entered  into a  Service  Provider
   Agreement with Iceland Telecom,  an Icelandic company,  which is the EUTELSAT
   signatory for Iceland.  The Agreement  appoints  BOATRACS (Europe) B.V. to be
   the maritime service  provider of the EUTELTRACS  service for Iceland and its
   territorial waters.

   Agreements with British Telecom

   In July,  1998, the Company  entered into  agreements with British Telecom to
become an Inmarsat provider.

   Regulation

   Domestic Operations

   BOATRACS'  products are subject to various FCC  regulations in the U.S. These
   regulations require that the Company's  communications  products meet certain
   radio frequency emission standards and not cause unallowable  interference to
   other  services.  QUALCOMM filed an  application  with the FCC for a standard
   experimental license with a two-year term, which was granted effective August
   18, 1995. In addition,  QUALCOMM  pursued a Petition for Rulemaking  which it
   filed  with  the FCC in 1992 to amend  the  Table  of  Frequency  Allocations
   permitting  non-experimental use of the frequencies utilized by the OmniTRACS
   system in the United States coastal waters.  Effective  January 3, 1997, this
   license was granted to QUALCOMM,  which added marine  capability  to use with
   the OmniTRACS system for up to 100,000 MCTs for a term of 10 years. There can
   be no assurance that QUALCOMM's current license will continue to be renewed.

   International Operations

   BOATRACS  intends to continue its  expansion  into  additional  international
   markets.  In countries  which  QUALCOMM has an affiliated  OmniTRACS  service
   provider,  BOATRACS  believes that such affiliate or BOATRACS will attempt to
   secure the  necessary  regulatory  approvals,  licenses  and/or  permits  and
   renewals  thereof  for  maritime  applications  from the  local  governmental
   authorities for the affiliate or BOATRACS.  In countries in which no QUALCOMM
   affiliate  is  operating,  BOATRACS  will  apply  to the  local  governmental
   authority for  applicable  approvals,  licenses  and/or  permits and renewals
   thereof.  No assurance  can be given that BOATRACS will be able to obtain the
   required approvals,  licenses and/or permits and renewals thereof.  BOATRACS,
   through BOATRACS (Europe) B.V.  maintains a sales and customer support office
   in Leiden, The Netherlands. Currently, BOATRACS has MCTs installed on vessels
   in a number of countries in Europe.

   Additional Products

   ENERDYNE  continues to develop new video  compression and related products to
   complement the Company's  product lines.  The products are sold to ENERDYNE's
   customers under ENERDYNE respective proprietary names.

   The Company is seeking  strategic  alliances  with companies that have proven
   products or service in markets requiring video. In addition, the Company uses
   its commercially  reasonable best efforts to stay abreast of new products and
   services that can complement its existing  product and service  offerings and
   seeks to build  additional  strategic  relationships  with companies that are
   developing  new  solutions  for  the  respective  businesses  including:  (i)
   interfaces and marine related products that require  communications between a
   vessel  and the  shore  and (ii) new  video  compression  relationships.  The
   Company continues to explore ways to economically enhance these relationships
   by acquiring either sales and distribution rights to, or direct ownership of,
   the products  developed.  The Company  believes  that these  efforts have the
   potential to result in significant  growth in increased sales of products and
   messaging volume.

   In March,  1998, the BOATRACS division amended the reseller  arrangement with
   Orbital  Communications  Corporation  ("ORBCOMM"),   which  is  developing  a
   Low-Earth Orbit system ("LEO"), pursuant to which the Company will distribute
   ORBCOMM's  LEO  services on a non  exclusive  basis to the  worldwide  marine
   market when such services become commercially  available.  The LEO system, if
   it proves successful, will complement the Company's present services. ORBCOMM
   estimates the system will be completely operational during 1999.

   The Company is also an Inmarsat  provider.  As an Inmarsat provider and Agent
   of Inmarsat services,  the Company will be able to provide global coverage to
   customers. See - "Risks of Offering New Services."

   Research and Development

   During 1998 and 1997 the Company spent $243,000 and $199,000  respectively on
   the research and  development of software to complement  the BOATRACS  System
   and  ENERDYNE  systems.  These  costs  were not  passed  on to the  Company's
   customers.

   Market Expansion

   The Company  believes that there is a sizable market in the United States and
   abroad for its products and has developed  strategies to expand into selected
   markets by providing  innovative solutions to customer needs. There can be no
   assurance  that  any  of the  Company's  market  expansion  efforts  will  be
   successful.

   ENERDYNE's  products   specifically   address  four  segments  of  the  video
   compression  market:  Defense,   Intelligent  Transportation  Systems  (ITS),
   Surveillance  and  Aerospace.  ENERDYNE plans to explore new markets that are
   large and expanding and develop new products for market expansion.

   The Company  believes that there are increased  opportunities  for ENERDYNE's
   products in the intelligent  transportation  systems market ("ITS").  Uses of
   video compression products include highway surveillance/monitoring, wide area
   detection,  ramp monitoring,  toll evasion  verification,  emergency  medical
   services and toll booth  security.  The Company is informed and believes that
   the  United  States   government  has  appropriated   $218  billion  via  the
   Transportation  Equity Act over the next five years,  a portion of which will
   be dedicated to ITS. There also appears to be opportunities  overseas for the
   ENERDYNE  technology.  It is  anticipated  that market  expansion  will be in
   government,  military  and private  industries  working  with  transportation
   management systems. The potential end user will be a federal,  state or local
   governmental agency responsible for traffic management in their jurisdiction.
   There can be no assurance that the Company's beliefs are accurate.

   Sales and Distribution

   BOATRACS

   Since its inception,  the Company has employed an internal direct sales force
   and has engaged sales  representatives  to place the Company's  products with
   marine  electronics  dealers,  which sell to the end user.  In addition,  the
   Company is continually seeking  relationships with third-party  distributors,
   which can provide  sales and service  support for its  products.  The Company
   believes  that such  arrangements  have the  potential  to result in sales in
   areas where it is not cost-effective to have a full-time salesperson.  In the
   New England and Atlantic  fishing markets the Company has agreements with ten
   dealers.

   ENERDYNE

   ENERDYNE  typically  sells its product  directly to customers  through direct
   sales and  marketing  employees.  In addition the Company  uses  manufactures
   representatives  and also sells to system  integrators who then package these
   products with others to achieve a universal solution for a customer.

   Competition

   BOATRACS

   The  mobile  communications  industry  is highly  competitive.  The  industry
   includes  major  domestic  and  international  companies,  many of which have
   financial,  technical,  marketing,  sales,  distribution  and other resources
   substantially  greater than those of the Company. The Company competes in its
   market on the basis of product quality, reliability,  price, customer support
   and  product  features.  BOATRACS  believes  that it is  currently  generally
   competitive  with  respect  to  each  of  these  factors.  However,  BOATRACS
   competitors are aggressively  pricing their products and will likely continue
   to do so in the future. In addition, competitors are offering new value-added
   products and services  similar to those  developed or being  developed by the
   Company  or  QUALCOMM.  Emergence  of  new  competitors,  particularly  those
   offering lower cost products, enhancements, additional features and Low-Earth
   Orbit  (LEO)  satellite   communications  systems,  may  impact  margins  and
   intensify  competition in new markets.  Two LEO systems offer voice;  IRIDIUM
   which is now  commercially  available and GLOBALSTAR which is scheduled to be
   available in the near future. Due to their long-term  unproven  capabilities,
   the Company  cannot  predict how their  products  and  services  will compete
   directly against the BOATRACS existing products and services.  The Company is
   exploring  ways to compete  and/or offer these new generation of products and
   services.  However, the new competition could have a material impact upon the
   BOATRACS business.

   The  following is an overview of certain  products and services  that compete
   with BOATRACS' communications products and services:

   Alternative  Satellite Service Providers.  Several competing entities provide
   satellite-based mobile voice and data systems in marine markets. INMARSAT, an
   international  consortium,   provides  maritime  voice,  facsimile  and  data
   services nearly worldwide using capacity on a combination of owned and leased
   satellites.  American  Mobile  Satellite  Corporation  currently  offers data
   communications and vessel tracking using its newly launched L-band satellite,
   and  a  voice-based   system.   ARGOS   provides   one-way  (ship  to  shore)
   communications  and position reporting in many parts of the world. When ARGOS
   operates  on  the   Japanese   ADEOS2   satellite   it  will  offer   two-way
   communication.  INMARSAT is approved to provide Global Marine Distress Safety
   System ("GMDSS") notices and communications.  GMDSS requires shipping vessels
   of a certain  nature and size that  operates  certain  routes to have a GMDSS
   approved communications system by February,  1999. The BOATRACS System cannot
   become GMDSS approved because the BOATRACS  System's  coverage is not global.
   The Company is at a disadvantage without such approval.

   Radio.  Although radios are required for most vessels,  many small businesses
   rely  exclusively  on radios for their  communication  needs  throughout  the
   marine industry. Radio can be used to communicate with a marine operator, who
   can in  turn  place a long  distance  telephone  call  for  the  radio  user.
   Typically,  the cost of the marine  operator  together with the long distance
   telephone  charges can be  significant.  Radio is not dependable in inclement
   weather, lacks confidentiality, and does not always provide a clear signal.

   H F Radio.  At least one  competitor,  Globe  Wireless,  Inc., now operates a
   network of H F radio stations that allow for email  capabilities and transfer
   of data files.  Globe Wireless,  Inc.,  states that its system operates "much
   like a digital cellular network except it is worldwide". Globe Wireless, Inc.
   competes directly with the Company.  They have also advertised the ability to
   deliver software system solutions for its customers. The Company is uncertain
   whether H F radio is as dependable as satellite communications.

   Cellular phone.  Cellular phone provides clear,  easy to use communication to
   many boats  including  pleasure boats and commercial  shipping,  workboat and
   towing  operators.  Although a cellular system provides a clear hook-up and a
   reliable  service,  it is currently  relatively more expensive.  The cellular
   range is also  limited  because  the  networks  of cell sites were  placed in
   locations most suitable for automobiles and not for vessels.  This means that
   coverage  on the water is limited.  Cellular  phones are usually out of range
   ten  miles  from  the  coast;   however,  in  the  United  States,   Waterway
   Communications  Systems,  Inc.  ("Watercomm")  provides  cellular radio phone
   service for vessels operating on inland  waterways.  Watercomm phones utilize
   radio towers placed along the major U.S. rivers to send and receive voice and
   data  transmissions.  Watercomm users incur a connection  charge as well as a
   per-minute usage charge,  based on where the vessel is operating.  In Europe,
   GSM, the European cellular phone service, offers extensive coverage and plans
   to provide coverage to nearly all of Europe's population.  GSM cellular phone
   service also provides a user the  convenience of using a single phone in many
   different  countries;  however,  there are  significant  roaming charges when
   roaming in a non-home country.

   ENERDYNE

   Video Compression  Products.  ENERDYNE competes with a number of companies in
   its current  markets each of which  provides one or more products  offered by
   the Company and some of which have access to greater financial resources. The
   following are significant competitors to the ENERDYNE products and services:

   Proprietary Information

   The Company relies on a combination of copyrights,  trade secrets, trademarks
   and proprietary information to maintain and enhance its competitive position.
   According  to reports  filed with the  Commission,  QUALCOMM has been granted
   United  States  patents  and has  patent  applications  pending in the United
   States with respect to the OmniTRACS System.  QUALCOMM has also reported that
   it actively pursues patent  protection in other countries of interest,  which
   protection may or may not cover OmniTRACS products.

   ENERDYNE  currently  holds one patent in the  United  States,  Patent  Number
   5633686 for an Adaptive  Digital Video System.  The patent covers a system in
   which a decoder at a receiving station for a digitally encoded signal is able
   to automatically  adapt to varying formats and operating modes. The method is
   independent of the particular  video format or compression  scheme  employed,
   and functions  with any  transmission  medium and  bandwidth.  The patent was
   filed on September  14, 1994 and issued on May 27, 1997.  ENERDYNE  currently
   has two trademarks: ADVS(R) (Adaptive Video Standard) and Passlink(TM).

   Employees

   At December 31, 1998, the Company and its subsidiaries had 60 full-time and 7
part-time employees.

   RISK FACTORS

   The Company wishes to caution readers that the following risk factors,  among
   others,  in some cases have  affected,  and in the future could  affect,  the
   Company's  actual results and could cause the Company's actual results in the
   future to differ  materially  from  those  expressed  in any  forward-looking
   statements made by, or on behalf of, the Company.

   The  foundation  of the  Company's  maritime  communications  business is the
   License and Distribution  Agreement between QUALCOMM and the Company pursuant
   to which BOATRACS has exclusive  distribution rights in the United States for
   marine application of the OmniTRACS system of satellite-based  communications
   and tracking systems manufactured by QUALCOMM.  QUALCOMM is the sole supplier
   of the core  communications  equipment sold by BOATRACS and provides  certain
   services that are essential to the BOATRACS business.  If QUALCOMM decides to
   discontinue its satellite  communications business or the manufacture of such
   equipment,  the Company  would be unable to continue its core  communications
   business.  While BOATRACS has an agreement with QUALCOMM for the products and
   services  provided by it,  QUALCOMM has the right to terminate this Agreement
   under  certain  circumstances.   In  addition,  any  manufacturing  delay  or
   difficulty in procuring  components  experienced  by QUALCOMM  resulting in a
   shortage of available OmniTRACS units could have a material adverse impact on
   the  BOATRACS'  business  and  financial  results.   Under  the  License  and
   Distribution  Agreement,   QUALCOMM  retains  all  ownership  rights  to  the
   OmniTRACS software and all updates,  upgrades,  improvements or modifications
   thereto,  whether  made by QUALCOMM or  BOATRACS.  Additionally,  BOATRACS is
   dependent upon  QUALCOMM's  OmniTRACS  system,  which  currently  operates on
   leased Ku-band satellite  transponders in the areas where BOATRACS is active.
   BOATRACS has been  informed that in the United  States  QUALCOMM's  satellite
   transponder lease and the position reporting satellite  transponder lease run
   through the year 2001.  QUALCOMM has informed to the Company that it believes
   any additional required  transponder capacity will be available on acceptable
   terms.  However,  there can be no assurance  that the satellite  transponders
   leased by QUALCOMM  will  continue  to  function  or that future  transponder
   capacity  will be available on acceptable  terms when needed.  Any failure by
   QUALCOMM  to  maintain  adequate  satellite  capacity  would  have a material
   adverse effect on the Company's business and financial results.

   BOATRACS does not have direct contracts with satellite providers.  In Europe,
   BOATRACS relies on its service supplier,  ALCATEL QUALCOMM, which in turn has
   a relationship with EUTELSAT,  the satellite  provider.  In Canada,  BOATRACS
   relies on its service provider,  CANCOM Mobile,  which has relationships with
   Canadian satellite  providers.  In the United States,  BOATRACS relies on its
   service  provider,  QUALCOMM who in turn has a  relationship  with  satellite
   providers  in the United  States.  The Company is not privy to the details of
   their service providers' contracts with satellite providers.  There can be no
   assurance that the transponders used in Europe,  Canada and the United States
   will  continue  to  function  or that  future  transponder  capacity  will be
   available  on  acceptable  terms as needed.  Any failure by the  providers to
   maintain adequate  satellite capacity would have a material adverse effect on
   BOATRACS' business and financial results.

   The  messaging  service  provided by BOATRACS  involves  data  transfers  via
   standard telephone lines.  BOATRACS  operations rely upon the availability of
   stable  telephone   connections   between  BOATRACS  and  QUALCOMM's  Network
   Management  Facility and between  BOATRACS,  its customers,  the Internet and
   QUALCOMM's  Network Management  Facility.  See "Business -- The OmniTRACS and
   BOATRACS Systems." Any system failure or natural disaster that resulted in an
   interruption of stable telephone service would have a material adverse effect
   on the Company's business and financial results.

   According  to reports  filed with the  Commission,  QUALCOMM has been granted
   United  States  patents  and has  patent  applications  pending in the United
   States with respect to its OmniTRACS system, which is distributed by BOATRACS
   for marine applications.  QUALCOMM has also reported that it actively pursues
   patent protection in other countries of interest, which protection may or may
   not cover  OmniTRACS  products.  There can be no  assurance  that the pending
   patent  applications will be granted,  that QUALCOMM's  patents or copyrights
   will provide adequate protection,  or that competitors will not independently
   develop or patent technologies that are substantially  equivalent or superior
   to the  OmniTRACS  System.  From time to time,  certain  companies may assert
   exclusive  patent,  copyright  and  other  intellectual  property  rights  to
   technologies,  which  are  important  to  the  industry  or to  the  products
   distributed  by  BOATRACS.   If  QUALCOMM  is  unable  to  license  protected
   technology  used in its products,  or if the OmniTRACS  product were found to
   infringe on protected technology, QUALCOMM could be prohibited from marketing
   such products.  In such  circumstances,  BOATRACS would be unable to continue
   its operations.

   ENERDYNE  holds a patent in the United States for its Adaptive  Digital Video
   System. Should ENERDYNE's competitors develop or patent technologies that are
   substantially  equivalent  or  superior  to  ENERDYNE's  patent,   ENERDYNE's
   position in the market could be compromised.

   The  integration  of the  BOATRACS  and  ENERDYNE's  operations  will require
   substantial  capital funding and the dedication of management  resources that
   may  temporarily  detract  attention  from the  day-to-day  operations of the
   combined  company.  The  combination  of the two companies  will also require
   coordination  of their  research  and  development  and sales  and  marketing
   efforts.  The difficulties of combining the two companies may be increased by
   the  necessity  of  coordinating   geographically   separated  organizations,
   integrating  personnel with disparate business  backgrounds and combining two
   different corporate cultures.  The process of combining the two organizations
   may cause an  interruption  of, or a loss of momentum in, the  activities  of
   either or both of the  companies'  businesses,  which  could  have an adverse
   effect on the revenue and operating results of the combined company, at least
   in the near term.  There can be no assurance that the combined entity will be
   able to  retain  its key  technical  and  management  personnel  or that  the
   combined entity will realize any of the  anticipated  benefits of the merger.
   Failure to  effectively  accomplish  the  integration  of the two  companies'
   operations could have an adverse effect on the combined  company's results of
   operations and financial condition.

   ENERDYNE has relied heavily on the  transportation  and governmental  markets
   for its revenues.  Military and other governmental spending cuts could impact
   profits.  ENERDYNE relies on continuing technological  innovation,  including
   innovations which are internally  generated and technology developed by third
   parties.  Competing  technologies could impact revenues and profit margins as
   well as  provide  incentive  for  more  competition.  Devoting  resources  to
   internally  generated  technological  innovation  would  require  devotion of
   engineering,  sales and marketing  resources which might result in a shift in
   focus from existing product lines and markets.  Technological  innovation may
   also lead to obsolescence of components used in ENERDYNE's products or create
   compatibility problems with existing units.

   BOATRACS  has  many  customers  in the oil  industry  in the  United  States.
   Currently,  the oil industry is depressed and oil prices are very low.  There
   is no assurance  that  BOATRACS  customers in this  industry  will be able to
   withstand the recession in the industry. Customers may be forced to terminate
   messaging  and software  services  with  BOATRACS  and the BOATRACS  Gulfport
   division which could have a material adverse effect on BOATRACS' business and
   financial results.

   The  Company  may be  required  to  raise  additional  capital  to  fund  the
   operations and growth of its combined companies.  The Company cannot, at this
   time, determine the amount of capital, which will be required, or the sources
   of that  capital.  The  issuance of common  stock and warrants and options to
   purchase common stock will result in dilution to existing shareholders.

   In countries in which BOATRACS  contracts  with  QUALCOMM's  local  OmniTRACS
   service  provider,  BOATRACS  believes that such service provider or BOATRACS
   will be responsible for securing the necessary regulatory approvals, licenses
   and permits and/or  renewals  thereof for maritime  operations from the local
   governments and authorities. BOATRACS and such local service providers may be
   less prominent in such  international  markets than local competitors and may
   have less  opportunity  to influence  regulatory and standards  policies.  In
   countries  in  which   BOATRACS   contracts   with   distributors   of  other
   communications  systems,  BOATRACS  may  apply to the local  governments  for
   applicable approvals. No assurance can be given that BOATRACS will be able to
   obtain the required approvals,  licenses and permits and/or renewals thereof.
   Changes in the regulation of QUALCOMM's OmniTRACS system, or the inability to
   obtain foreign  regulatory  approvals,  licenses and permits and/or  renewals
   thereof,  could have a material adverse effect on BOATRACS  operating results
   and its ability to expand its business in the future.

   The mobile communications industry is highly competitive. See "Competition".

   ENERDYNE  competes with a number of companies in its current market,  each of
   which  provides  one or more  products  offered by ENERDYNE and some of which
   have access to greater financial resources. ENERDYNE faces increased domestic
   competition,  and as technological  innovation becomes more available foreign
   and domestic  competition is increasing.  There is no assurance that ENERDYNE
   will continue to be competitive in its existing and prospective  markets. See
   "Business -- Competition."

   The sales cycle of BOATRACS and ENERDYNE is not even throughout the year. The
   sales process takes a considerable amount of time for both companies to close
   a sale. ENERDYNE's customers are often governmental departments and the sales
   cycle is often  slow to  complete.  In  addition,  the sales  staff may spend
   considerable time on sales leads which do not come to fruition.
    The Company is currently  expanding its operations  abroad.  The Company has
   limited experience in managing foreign  operations.  International  expansion
   efforts are likely to strain the  Company's  management,  financial and other
   resources.  Any failure of the Company to expand in an efficient manner or to
   manage its dispersed organization could have a material adverse impact on the
   Company's business and financial  results.  Other risks that will be faced by
   the  Company  in  its   international   business  include  costly  regulatory
   requirements;  unexpected changes in regulatory requirements;  application of
   foreign law;  fluctuations in currency exchange rates (which could materially
   and adversely affect the Company's results of operation and, in addition, may
   have an adverse effect on demand for the Company's products abroad);  tariffs
   or other barriers;  difficulties in staffing and managing foreign operations;
   political  and  economic  instability;  difficulties  in accounts  receivable
   collection;   extended   payment   terms;   and   potentially   negative  tax
   consequences.  Additionally,  ENERDYNE's  products  and  technology  could be
   subject to restrictions  on sales to certain foreign  countries by the United
   States  Government.  These  factors  could  have  an  adverse  impact  on the
   Company's business and financial results in the future or require the Company
   to modify its current business practices.

   The  Company  recently  became  an  INMARSAT  provider.  Even as an  INMARSAT
   provider,  the  Company  will  continue  to compete  against  other  INMARSAT
   providers. The Company has limited experience in reselling INMARSAT services.
   Such  expansion of service and product  offerings  could strain the resources
   and possibly deteriorate the Company's  reputation with customers,  and could
   have a material adverse impact on the Company's core communications business.
   See "Business -- Market Expansion."

   The  Company's  products are subject to various FCC  regulations  in the U.S.
   These  regulations  require that the  Company's  products  meet certain radio
   frequency emission standards and not cause unallowable  interference to other
   services.  QUALCOMM  filed  an  application  with  the  FCC  for  a  standard
   experimental license with a two-year term, which was granted effective August
   18, 1995. In addition,  QUALCOMM pursued a Petition for Rulemaking,  which it
   filed,  with the FCC in 1992 to amend  the  Table  of  Frequency  Allocations
   permitting  non-experimental use of the frequencies utilized by the OmniTRACS
   system in the United States coastal waters.  Effective  January 3, 1997, this
   license was granted to QUALCOMM,  which added marine  capability  to use with
   the OmniTRACS system for up to 100,000 mobile  communication  terminals for a
   term of 10 years.  There can be no assurance that QUALCOMM's  current license
   will  continue to be renewed.  In the event of  non-renewal  or revocation of
   QUALCOMM's license by the FCC, the License and Distribution Agreement between
   QUALCOMM and the Company may be  terminated  and the Company may be unable to
   continue its United States operations.

   Pursuant to the License  and  Distribution  Agreement  between  QUALCOMM  and
   BOATRACS,  if the Company desires to sell its business,  QUALCOMM has a right
   of first refusal to purchase the Company's  business on the terms of the sale
   to the proposed transferee. QUALCOMM's right of first refusal could adversely
   affect the  ability  of the  Company to sell its  business  to a third  party
   purchaser.

   The Company is subject to a number of other risks, including:  loss of senior
   management;  dependence on large  customers  concentrated  in the  commercial
   marine industry; loss of fishing resources which are in decline in many areas
   of the world; the risks associated with  international  expansion,  including
   local  regulatory  requirements,  no prior  experience  in  managing  foreign
   operations,   and   fluctuations  in  currency   exchange  rates;   operating
   restrictions  imposed by contractual  relationships with foreign firms; risks
   associated  with  business   expansion  and  the  acquisition  of  additional
   businesses; competition with companies that have greater financial, technical
   and  marketing  resources  than the Company;  fluctuations  in the  Company's
   quarterly  operating results;  and lack of liquidity for the Company's common
   stock,  which could result in significant  price  fluctuations in response to
   operating results and other factors.  In addition,  the Company is subject to
   foreign regulations,  export restrictions and limitations on foreign sales to
   certain countries.

   Year  2000  Issues.  In the  operation  of its  business,  the  Company  uses
   commercial   computer  software  primarily  purchased  from  or  provided  by
   independent software vendors.  After an analysis of the Company's exposure to
   the impact of "year 2000 issues" (i.e.  issues that may arise  resulting from
   computer programs that use only the last two, rather than all four, digits of
   the year),  the Company  believes  that such  commercial  software is already
   substantially  year  2000  compliant,   and  that  completion  of  year  2000
   compliance  should  not have a  material  impact on the  Company's  business,
   operations or financial  condition;  however,  the Company is still assessing
   the impact of this year 2000 issue.

   The  Company has  performed  an  internal  analysis  and is in the process of
   finalizing  a specific  written plan to address the year 2000 issues for both
   internally  developed  products and products  developed and  manufactured  by
   Qualcomm.  Qualcomm has assured the Company that all the products supplied to
   the Company during the course of the  relationship  and going forward will be
   upgraded to ensure  compliance with Year 2000 standards.  This assurance will
   be at no charge to the Company or  customers  but the Company may be required
   to exchange certain chip sets of its customers at minimal cost.

   For internally  developed products,  the upgrade process is in final phase of
   testing  and  will  be  completed  by the  end of the  current  fiscal  year.
   Development   costs  associated  with  the  upgrade  have  been  included  in
   operations  as  incurred.  The Company has spent a total of $15,000 on the 
   conversion and the potential  future cost to complete  the  conversion  is 
   estimated at $25,000 in total which will also be included in operations as 
   incurred.

   The Company is not in a position to evaluate the extent (if any) to which any
   year 2000 issues that may affect the economy  generally  or any  suppliers or
   others with whom the Company does  business in  particular  would also affect
   the Company. Failure of one or more of the supplier's computer products to be
   year 2000 compliant would have a material effect on the Company's business.

   ITEM 2. DESCRIPTION OF PROPERTY

   The corporate office leases its facilities in San Diego, California,  under a
   four and a half-year,  non-cancelable operating lease, which expires December
   2002.  The Company  relocated to this facility in July,  1998.  The Company's
   leases have rent  escalation  terms based on the Consumer Price Index,  which
   will affect future  minimum lease  payments.  The Company also leases a 9,800
   square foot  building in Santee,  California  for ENERDYNE  which  expires in
   July, 1999, and a 2,507 square foot facility in Gulfport,  Mississippi, which
   expires in January,  2000.  Boatracs  (Europe)  B.V.,  operates a facility in
   Leiden, The Netherlands  pursuant to a lease expiring in December 2001. Total
   rent expense was $217,157,  $57,894 and $51,900 for the years ended  December
   31, 1998, 1997 and 1996 respectively.

   ITEM 3.  LEGAL PROCEEDINGS

   The Company is not aware of any current or pending legal proceedings to which
the Company is a party.

   ITEM 4.  SUBMISSION OF MATTERS TO A VOTE OF SECURITY HOLDERS

   common stock at $4.44 per share to Sol Price in connection with a purchase of
   a  promissory  note  from a  director  and an  officer  of the  Company.  The
   securities  were issued in reliance on the exemption set forth in 4(2) of the
   Securities Act of 1933.

   Effective July 1998, the Company agreed to issue 5,000 shares of common stock
   valued at $4.75 per share in connection  with the  acquisition of Oceantracs,
   Inc. The  securities  were issued in reliance on the  exemption  set forth in
   4(2) of the Securities Act of 1933.

   In  July  1998,  the  Company  acquired  ENERDYNE  for  $22.6  million  in  a
   combination  of cash,  stock and  notes.  A total of  3,000,000  shares  were
   issued,  2,930,700  of which to the former  shareholders  of ENERDYNE and the
   remainder  to the  financial  advisors.  In  addition  the former  owners and
   financial  advisors received a total of 1,000,000 warrants to purchase common
   stock at a price of $2.00.  The  securities  were  issued in  reliance on the
   exemption set forth in 4(2) of the Securities Act of 1933.

   ITEM 6.  MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND 
            RESULTS OF OPERATIONS

   Overview

   The Company has two main business units:
         1.  BOATRACS, Inc. ("BOATRACS"), and
         2.  Enerdyne Technologies, Inc. ("ENERDYNE"), a wholly owned 
             subsidiary.
   BOATRACS

   Effective  November 1, 1997, the Company  acquired certain assets of BOATRACS
   Gulfport for $500,000 cash and 300,000 shares of Common Stock valued at $1.40
   per share. The acquisition agreement was amended in December,  1998 resulting
   in a reduction of notes payable to $30,000 from $250,000 and the common stock
   issued to 240,000 shares from 300,000. The assets and liabilities of BOATRACS
   Gulfport are reflected on the consolidated  balance sheets as of December 31,
   1998 and  December 31, 1997.  The results of BOATRACS  Gulfport's  operations
   from the date of the  acquisition to December 31, 1997 were not  significant.
   Goodwill in the amount of $845,000 was originally recorded in the acquisition
   and adjusted to $541,000 and is amortized over ten years.

   Effective July 1, 1998, the Company acquired all of the outstanding shares in
   OceanTrac  Inc., a Canadian  corporation  ("OceanTrac").  The acquisition was
   effected  by the  exercise  of the  Company's  rights  under a Joint  Venture
   Agreement  entered into among the Company,  OceanTrac and  OceanTrac  Systems
   Limited, a Nova Scotia corporation  ("Systems") during 1996. In addition, the
   Company  purchased  all of the assets of Systems for  consideration  of 5,000
   shares of the  Company's  Common  Stock.  The  acquisition  of OceanTrac  and
   Systems  resulted in recording of intangibles in the amount of  approximately
   $388,000  which will be amortized  by the Company  over ten years.  OceanTrac
   will continue to act as the Company's appointed  distributor of the OmniTRACS
   system and related Company products.

   ENERDYNE

   On July 7, 1998,  the Company  acquired  ENERDYNE by means of a merger with a
   wholly owned subsidiary of the Company.  ENERDYNE is a provider of versatile,
   high  performance  digital video  compression  products to the government and
   commercial  markets.   ENERDYNE,  formed  in  1983,  is  located  in  Santee,
   California.  The  acquisition  price  of  $22.6  million  was  paid  for by a
   combination   of  cash,   Common  Stock  and  notes   payable.   Patents in 
   the amount of $18 million and goodwill in the amount of $10.5 million were
   recorded and each will be amortized  over sixteen years. The two shareholders
   of ENERDYNE signed employment  contracts with the Company for one and two 
   years, respectively, and one shareholder was elected to the Board of 
   Directors in September  1998. 

   A First Amendment to the Agreement and Plan of Reorganization, in connection
   with the Enerdyne acquisition was executed effective July 7, 1998. The 
   Amendment increased the number of compensatory option shares and exercise 
   price subject to a specific paydown on the acquisition notes payable to the
   selling shareholders.  On December 29, 1998 bank financing was obtained to 
   effect the compensatory contingency per the Amendment and the options were
   revised to 663,500 at an exercise price of $2.65 in accordance with the
   calculations and provisions in the Amendment.
     

   The acquisitions of BOATRACS Gulfport,  ENERDYNE and OceanTrac  represent the
   Company's continuing efforts to diversify its operations. The Company intends
   to continue to evaluate other acquisition opportunities.

   The Company earns revenue primarily from four sources: (a) sales of satellite
   based  communications  equipment and software and  additional,  complementary
   and/or  modified  equipment  created  or  procured  by  BOATRACS  for  marine
   application;  (b) data  transmission  and  messaging  charges;  (c)  software
   license fees and charges for custom  software  development  solutions and (d)
   development and sales of video compression products.

   The Company recognizes revenues from the sale of communication systems at the
   time the equipment is shipped to the customer. The Company recognizes revenue
   from  messaging at the time the  transmission  is made by the  customer.  The
   Company recognizes software license and development revenues as incurred. The
   Company recognizes revenues from the sale of video compression units which do
   not entail significant customer modification upon shipment to customers,  and
   on the  percentage of completion  method for products  requiring  significant
   customer modification or the development of new technology.

<PAGE>


   Years ended December 31, 1998 and 1997

   Total   revenues  for  the  twelve  months  ended   December  31,  1998  were
   $10,173,320, an increase of $4,969,404 or 95.5% as compared to total revenues
   of $5,203,916 for the prior year ended December 31, 1997.

   Communications  systems  revenues  which consist of revenues from the sale of
   BOATRACS  systems,  related  software and revenues of BOATRACS  Gulfport were
   $4,033,264  or 39.7% of total  revenues,  an increase of  $1,620,251 or 67.2%
   compared to $2,413,013 or 46.4% of total revenues for the year ended December
   31,1997. The increase in communication  systems revenues compared to the same
   period in the prior year, primarily reflects increased sales of communication
   units to vessels in the United  States in the amount of  $1,075,196 or 86.5%.
   Software  revenues from  BOATRACS  Gulfport,  which was  purchased  effective
   November,  1997,  increased by  $1,026,606,  compared to the revenues for two
   months of the prior year. The increase was partially  offset by a decrease in
   communication  sales in Europe and Canada in the  amount of  $468,705  or 66%
   during 1998.  Data  transmission  and messaging  revenues were  $3,881,244 or
   38.2% of total  revenues,  an increase  of  $1,090,341  or 39.1%  compared to
   $2,790,903  or 53.6% of total  revenues  in the prior year.  The  increase in
   revenues  reflects an overall  increase in data  transmission  and  messaging
   services provided by BOATRACS as a result of growth in the number of BOATRACS
   systems installed on vessels. Video compression revenues,  which are revenues
   from ENERDYNE,  which the company  acquired in July, 1998, were $2,258,812 or
   22.2% of total revenues.

   Communication  systems  expenses were  $2,460,359 or 61.0% of  communications
   systems  revenues  for the year ended  December  31,  1998,  an  increase  of
   $888,055  or  56.5%  compared  to  $1,572,304  which   represented  65.2%  of
   communications  systems  revenues in the prior year.  The dollar  increase in
   expenses  primarily  reflects the  increase in sales of BOATRACS  systems and
   software  expenses  of  BOATRACS  Gulfport.  Gross  margin for  communication
   systems  increased 4% to 39% from 35% in the prior year.  The increase in the
   margin  is  primarily  due to a  decrease  in the  cost  of  units  from  the
   manufacturer  during the second  half of the year.  Included in the margin is
   the  BOATRACS   Gulfport  margin  for  software  of  22%  during  1998.  Data
   transmission   and  messaging   expenses  were  $1,892,893  or  49%  of  data
   transmission and messaging  revenues for the year ended December 31, 1998, an
   increase  of  $474,432  or  33.5%  compared  to  $1,418,461  or 51%  of  data
   transmission  and messaging  revenues for the prior year. The dollar increase
   in costs reflects increased data transmission and messaging services rendered
   due to increased BOATRACS systems installed on vessels. The data transmission
   and messaging margin was relatively  unchanged at 51% in 1998 compared to 49%
   in 1997. The Company  received a reduction on costs from the service provider
   during the second half of 1998. This reduction was partially  offset by lower
   messaging margins in Canada and Europe.

   Selling,  general and administrative expenses for the year ended December 31,
   1998 were $4,755,523 or 46.8% of total revenues, an increase of $2,250,333 or
   89.8%  compared to $2,505,190  or 48.1% of total  revenues in the prior year.
   The  increased  dollar  amount is  primarily  attributable  to  increases  in
   operating expenses in connection with three  acquisitions,  which the Company
   has  entered  into since  November  1, 1997.  Accounting  and legal  expenses
   increased by a total of $163,406  primarily due to additional  Securities and
   Exchange  Commission  filings in connection  with the acquisition of ENERDYNE
   and BOATRACS  Gulfport  during 1998.  Salary expense  increased to $2,012,371
   from  $858,917,  an increase of $1,153,454  or 134%  primarily as a result of
   additional  employees due to acquisitions.  Office rent was $217,157 compared
   to  $57,894  in the  prior  year,  an  increase  of  $159,263  or 275% due to
   additional  offices and a new  BOATRACS  corporate  office  which the Company
   relocated to in July, 1998.  Insurance expense was $141,482 compared to total
   insurance  expense of $100,425  in the prior year,  an increase of $41,057 or
   41% primarily due to the additional  subsidiaries.  Amortization  expense for
   the year ended  December  31, 1998 was $966,429  due to the  amortization  of
   goodwill  recorded  as a result  of the  acquisition  of  BOATRACS  Gulfport,
   ENERDYNE  and  Oceantrac,  also  amortization  of a  patent  acquired  in the
   acquisition  of  ENERDYNE.  Depreciation  expense  was  $216,967  compared to
   $62,768  in the  prior  year,  an  increase  of  $154,199  or 246% due to the
   acquisition of the subsidiaries  assets and new assets acquired in connection
   with the corporate office relocation. The increase in expenses were offset by
   a  reduction  in  consulting  expense in the amount of $105,015 or 30% and an
   decrease in shareholder relations in the amount of $72,024 or 67%.

   Earnings before interest,  taxes,  depreciation and amortization for the year
   ended December 31, 1998 were $1,518,334  compared to a negative  $229,271 for
   the same period of the prior year.

   Interest  income of $47,423 for the year ended  December  31, 1998 relates to
   interest  earned on cash balances.  This  represents an increase of $8,211 or
   21%  compared  to  interest  income of  $39,212 in the prior  year.  Interest
   expense was  $413,335 for the year ended  December  31, 1998,  an increase of
   $411,275  compared to the prior  year.  Interest  expense in 1998  relates to
   interest  paid or  accrued on notes  payable  issued in  connection  with the
   purchase of Enerdyne.

   The income tax benefit  recorded in the amount of $422,210 for the year ended
   December 31, 1998  represents the  amortization of a temporary tax difference
   on the life of the Enerdyne patent.

   Years ended December 31, 1997 and 1996

   Total  revenues  for the year ended  December  31, 1997 were  $5,203,916,  an
   increase of $1,745,852 or 50% as compared to total revenues of $3,458,064 for
   the year ended December 31, 1996.

   Communications systems revenues,  which consists principally of revenues from
   the sale of BOATRACS  equipment and related software,  were $2,413,013 or 46%
   of total revenues, an increase of $1,028,309 or 74% over the prior year. This
   growth in  communications  systems  revenues is attributable  primarily to an
   increase  in sales of  equipment  to new  customers  in Europe and Canada and
   increased software sales in the United States.  Communication system revenues
   also includes two months  revenue of a software  applications  provider which
   the Company purchased effective November, 1997.

   Data transmission and messaging revenues, which consist of fees for messaging
   services provided to BOATRACS units installed on vessels,  were $2,790,903 or
   54% of total revenues,  an increase of $717,543 or 35% compared to $2,073,360
   or 60% of total revenues in the prior year. The increase in data transmission
   and messaging  revenues  primarily  reflects an overall increase in messaging
   services provided by the company as a result of growth in the number of units
   installed on vessels in prior periods and increased usage by some customers.

   Communications  systems  expenses were  $1,572,304  or 65% of  communications
   systems  Revenues  for 1996,  an increase  of  $702,358  or 81%,  compared to
   $869,946 which  represented 63% of  communications  systems revenues in 1996.
   The dollar increase in expenses primarily reflects increased  equipment sales
   in Europe and Canada and related  software.  The  increase in  communications
   systems  expenses  as a  percentage  of  communications  systems  revenues is
   primarily  due to the  inclusion  of two months of expenses  of the  recently
   purchased  software  applications   provider.   Without  these  expenses  the
   percentage  would be unchanged  from the prior year.  Data  transmission  and
   messaging  expenses were $1,418,461 or 51% of data transmission and messaging
   revenues in 1997,  an increase  of  $328,742 or 30%,  compared to  $1,089,719
   which  represented  53% of data  transmission  and messaging  revenues in the
   prior year. The dollar increase in costs reflects increased data transmission
   and messaging services rendered due to increased  equipment sales and related
   usage. The decrease in data  transmission  messaging costs as a percentage of
   data transmission  messaging revenues is due to increased margin on messaging
   services due to the continuing increase in revenues over the relatively fixed
   costs of providing this service, and increasing sales to fleet customers with
   greater utilization of the system.

   Selling,  general and administrative expenses were $2,505,190 or 48% of total
   revenues for 1997,  an increase of $44,172 or 2%,  compared to  $2,461,018 or
   71% of total  revenues  in the prior year.  The  increased  dollar  amount is
   primarily  attributable to various  increased  expenses  including salary and
   related expenses, outside consultants,  advertising and shareholder relations
   and certain prepaid consultant costs offset by a decrease in legal,  computer
   consultants,  telephone and European expenses. In 1997, the selling,  general
   and  administrative  expenses  include two months of expenses of the recently
   purchased software provider. In addition, selling, general and administrative
   expenses  include two months  amortization  of  goodwill  on the  purchase of
   BOATRACS Gulfport in the amount of $14,083.  The Company anticipates that the
   dollar amount of selling,  general and administrative  expenses will increase
   in the future to accommodate the Company's growth.

   Interest expense in 1997 was $2,060 or .04% of total revenues,  a decrease of
   $876 or 30% compared to $2,936 which was .08% of total  revenues in the prior
   year.  Interest  income was  $39,212 or .7% of total  revenues a decrease  of
   $20,905  or 35%  compared  to  $60,117  or 2% in the prior  year due to lower
   investment balances during 1997.

   As a result of the factors  described  above,  net loss was $254,887 for
   1997 compared to $905,438 for 1996, a decreased loss of $650,551 or 72%.

   Liquidity and Capital Resources

   The Company's cash balance at December 31, 1998 was $416,361,  an increase of
   $23,649,  or 6% over the  December  31,  1997 cash  balance of  $392,712.  At
   December 31, 1998,  working  capital was a negative  $182,858,  a decrease of
   $160,882  from the working  capital of $21,976 at December 31, 1997.  Cash of
   $101,639 was used in operating  activities,  cash of  $1,846,694  was used in
   investing  activities,  and cash of  $1,971,982  was  provided  by  financing
   activities during 1998.

   The Company's  liquidity was affected by $2 million paid for the  acquisition
   of ENERDYNE,  partially financed by the collection of a $2 million receivable
   for  stock  issued  during  the year  ended  December  31,  1998 to a Company
   director  and  officer.  As  partial  consideration  for the  acquisition  of
   ENERDYNE, the Company issued $10,000,000 of notes payable of which $8,000,000
   were due and payable in July,  1999  carrying an interest  rate of 8.5%.  The
   other note in the amount of $2,000,000 is a subordinated promissory note with
   specified  minimum annual payments and any remaining amounts payable June 31,
   2002 and bearing interest at 8.5%.

   On December 29, 1998, the Company signed a promissory note with a bank in the
   amount of $4,250,000 and used the proceeds to pay down the  $8,000,000  note.
   The interest rate on the promissory  note is 7.75% and will be paid over five
   years in monthly payments of $70,833 each.

   Accounts  receivable net of an allowance for uncollectible  amounts increased
   $1,383,394  to  $2,320,404 at year-end from $937,010 at December 31, 1997 due
   primarily  to the  acquisitions  made during 1998.  In  addition,  there were
   significant  increases in  inventories  in the amount of $450,645 and prepaid
   expenses in the amount of $151,944 due to the acquisitions  made during 1998.
   Property, net of accumulated depreciation, was $738,337 at December 31, 1998,
   an increase of $514,474 due primarily to the  acquisitions  completed  during
   1998 and the  relocation  of the  corporate  office.  Notes  receivable  were
   eliminated during 1998 from a balance of $310,463 at December 31, 1997 due to
   the acquisition of Oceantracs, Ltd. Goodwill, net of amortization,  increased
   by  $10,361,216  due  to  the  acquisition  of  ENERDYNE  in  the  amount  of
   $10,342,000  and the  acquisition of Oceantracs,  Ltd. In addition,  goodwill
   recorded in 1997 was reduced by $304,000 in December 1998, in connection with
   the acquisition of BOATRACS Gulfport.

   Accounts  payable were $1,068,347 at December 31, 1998, a decrease of $87,764
   or 8% compared to a balance of $1,156,111 in the prior year  primarily due to
   a reclassification of certain accruals to accrued expenses . Accrued expenses
   increased  by $821,831 or 338% to  $1,064,993  due  primarily  to  additional
   payroll accruals,  additional accruals due to the newly acquired subsidiaries
   and   reclassifications   between  accounts  payable  and  accrued  expenses.
   Acquisition costs payable was reduced by $250,000 due to a payment being made
   in the amount of $30,000  and  remainder  of the balance  being  reclassified
   reducing  goodwill.  Short-term  portion  of notes  payable  in the amount of
   $1,730,399  relates to the promissory note to a bank entered into in December
   1998 and notes owing to the previous owners of ENERDYNE.

   Any future funding  requirements  will be satisfied  through potential public
   and private  financing.  The known  resources  of  liquidity  of the Company,
   coupled with the projections for revenue, are expected to cover the Company's
   cash needs until at least the end of 1999.

   The Company  anticipates  making capital  expenditures  in excess of $200,000
   during  1999.  To date the Company has  financed  its working  capital  needs
   through  private  loans,  the  issuance  of  stock  and cash  generated  from
   operations.  Expansion of the Company's  business may require a commitment of
   substantial  funds.  To the extent that the net  proceeds  of recent  private
   financing  activities and internally generated funds are insufficient to fund
   the Company's operating requirements,  it may be necessary for the Company to
   seek additional funding, either through collaborative arrangements or through
   public or  private  financing.  There  can be no  assurance  that  additional
   financing  will be available  on  acceptable  terms or at all. If  additional
   funds are raised by  issuing  equity  securities,  dilution  to the  existing
   shareholders may result.  If adequate funds are not available,  the Company's
   business would be adversely affected.

INDEPENDENT AUDITORS' REPORT


To the Board of Directors and
    Stockholders of Boatracs, Inc.:

We have audited the accompanying  consolidated balance sheets of Boatracs,  Inc.
(the  "Company") as of December 31, 1998 and 1997, and the related  consolidated
statements of  operations,  stockholders'  equity and cash flows for each of the
three years in the period ended December 31, 1998.  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 consolidated  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 the Company at December 31, 1998
and 1997,  and the results of its  operations and its cash flows for each of the
three years in the period ended  December 31, 1998 in conformity  with generally
accepted accounting principles.

BOATRACS, INC.
NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
YEARS ENDED DECEMBER 31, 1998, 1997 AND 1996
- -------------------------------------------------------------------------------
1.   SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

     Nature of  Operations - BOATRACS,  Inc.  and its wholly owned  subsidiaries
     Enerdyne  Technologies,  Inc.  ("Enerdyne"),  OceanTrac,  Inc. and BOATRACS
     (Europe)  B.V.  (collectively  called  the  "Company")  is  engaged  in the
     business of  distribution of the OmniTRACS  satellite-based  communications
     and tracking system for marine application under a license and distribution
     agreement with QUALCOMM, Incorporated ("QUALCOMM", see Note 10) and is also
     a provider of video  compression  products to the government and commercial
     markets.   Under  the  QUALCOMM   agreement,   the  Company   sells  mobile
     communications  terminals and software for use on board marine  vessels and
     by marine dispatchers.  In addition, the Company also provides 24-hour data
     transmission  and messaging  services.  MED Associates,  Inc.  ("Gulfport")
     which was  acquired  by the  Company  in  November  1997 is a  provider  of
     software  applications  and service  solutions to the  commercial  workboat
     industry and to oil companies.

     Principles  of  Consolidation  - The  accompanying  consolidated  financial
     statements include the accounts of the Boatracs,  Inc. and its wholly owned
     subsidiaries. All significant intercompany balances have been eliminated in
     consolidation.

     Investment  Securities - Investment  securities  represented U.S.  Treasury
     securities  that the  Company  held to  maturity,  which were  reported  at
     amortized cost.

     Inventories - Inventories, comprising of raw materials, work in process and
     furnished goods, are carried at the lower of average cost or market.

     Property,  Patent and Goodwill - Property is recorded at cost. Depreciation
     is provided under the straight-line  method over the estimated useful lives
     of the assets  (generally 3-5 years).  Goodwill is amortized over 10 and 16
     years, and the Company's patent is amortized over 16 years.

     Revenue  Recognition  - Revenue from the sale of  communication  systems is
     recognized at the time the  equipment is shipped to the  customer.  Revenue
     from  messaging is recognized at the time the  transmission  is made by the
     customer.  Sales of standard video compression  units,  which do not entail
     significant  customer  modifications,   are  recognized  upon  shipment  of
     products to customers.  Revenues related to contracts involving significant
     customer modifications or the development of new technologies are accounted
     for using the  percentage-of-completion as costs are incurred. Products are
     subject to a right of return for one year. Actual return experience has not
     been significant.

     Significant Customers - For the Company's communications, data transmission
     and software revenues,  major customers individually accounted for 24%, 10%
     and 8% of 1998 sales, 18%, 12% and 9% of 1997 sales, and 26%, 12% and 8% of
     1996 sales.  Accounts  receivable from these customers  aggregated $387,432
     and  $437,077 at  December  31, 1998 and  December  31, 1997  respectively.
     Enerdyne's major video  compression  customers  individually  accounted for
     19%,  16%  and 10% of  sales  since  acquisition  date  in  1998.  Accounts
     receivable from these customers  aggregated  $270,994 at December 31, 1998.
     The Company and Enerdyne have not  historically  experienced  any losses on
     their accounts receivable.

     Stock-Based  Compensation - Statement of Financial Accounting Standards No.
     123,  "Accounting  for  Stock-Based  Compensation,"  encourages,  but  does
     require  companies to record  compensation  cost for  stock-based  employee
     compensation  plans at fair  value.  The  Company has chosen to continue to
     account for  stock-based  compensation  using the  intrinsic  value  method
     prescribed in Accounting  Principles Board Opinion No. 25, " Accounting for
     Stock  Issued to  Employees,"  and  related  Interpretations.  Accordingly,
     compensation  cost for stock options is measured as the excess,  if any, of
     the quoted  market  price of the  Company's  stock at the date of the grant
     over the exercise price.

     Net Income  (Loss) Per Share - Net  income  (loss) per share is  calculated
     using the weighted average number of shares  outstanding  during each year.
     In February 1997, the Financial  Accounting  Standards  Board (FASB) issued
     Statement of Financial  Accounting  Standards (SFAS) No. 128, "Earnings per
     Share" (EPS).  This  statement  requires the  presentation  of earnings per
     share to reflect  both  "Basic  EPS" and  "Diluted  EPS" on the face of the
     income  statement.  In the years ending December 31, 1997 and 1996,  common
     stock  equivalents  had an  anti-dilutive  effect  on  the  net  loss,  and
     therefore diluted EPS is not presented.

     Segment  Information - In 1998,  the FASB issued SFAS No. 131  "Disclosures
     about Segments of an Enterprise and Related Information".  Accordingly, the
     Company has disclosed all  applicable  results of operations by segment and
     geographic details as proscribed.

     Estimates - The  preparation  of financial  statements in  conformity  with
     generally  accepted  accounting  principles  requires  management  to  make
     estimates and  assumptions  that affect the reported  amounts of assets and
     liabilities and disclosure of contingent assets and liabilities at the date
     of the  financial  statements  and the  reported  amounts of  revenues  and
     expenses  during the  reporting  period.  Actual  results could differ from
     those estimates.

     Reclassifications  -  Certain  amounts  in  the  1997  and  1996  financial
     statements have been reclassified to conform to the 1998 presentation.

2.    ACQUISITIONS

     Enerdyne  Technologies,  Inc.  - On July 7,  1998,  the  Company  purchased
     Enerdyne  Technologies,  Inc. ("Enerdyne"),  a provider of versatile,  high
     performance  digital  video  compression  products  to the  government  and
     commercial  markets.  Enerdyne,  formed  in 1984,  is  located  in  Santee,
     California.  The  acquisition  price  of  $22.6  million  was paid for by a
     combination of cash, common stock and notes payable.  Patents in the amount
     of $18 million and goodwill in the amount of $10.5  million  were  recorded
     and will each be amortized over 16 years.  The two selling  shareholders of
     Enerdyne  signed  employment  contracts  with the  Company  for one and two
     years,  respectively,  and one selling shareholder was elected to the Board
     of Directors in September, 1998.

     A First Amendment to the Agreement and Plan of Reorganization ("Amendment")
     in connection with the Enerdyne  Acquisition was executed effective July 7,
     1998. The Amendment  increased the number of compensatory option shares and
     exercise  price  subject to a specific  paydown  on the  acquisition  notes
     payable to the selling  shareholders.  On December 29, 1998 bank  financing
     was obtained to effect the compensatory  contingency per the Amendment (see
     Notes  Payable - Note 6) and the  options  were  revised  to  663,500 at an
     exercise price of $2.65 in accordance with the  calculations and provisions
     in the Amendment.

     The following summarized unaudited pro forma financial  information assumes
     the acquisition had occurred on January 1 of each year:

          Weighted average common 
           shares outstanding,                20,309,195    16,677,000
           assuming dilution

     OceanTrac Inc. - Effective  July 1, 1998,  the Company  acquired all of the
     outstanding shares in OceanTrac Inc., a Canadian corporation ("OceanTrac").
     The acquisition was effected by the exercise of the Company's  rights under
     a 1996 Joint Venture  Agreement  entered into among the Company,  OceanTrac
     and OceanTrac Systems Limited,  a Nova Scotia corporation  ("Systems").  In
     addition,   the  Company  purchased  all  of  the  assets  of  Systems  for
     consideration of 5,000 shares of the Company's Common Stock valued at $4.75
     per share and foregiveness of notes totaling  $310,463.  The acquisition of
     OceanTrac and Systems resulted in recording of intangibles in the amount of
     approximately  $388,000  which will be  amortized  by the Company  over ten
     years.

     MED Associates,  Inc. - Effective  November 1, 1997, the Company  purchased
     certain assets and liabilities of MED  Associates,  Inc.  ("Gulfport")  for
     $500,000  cash,  and 300,000  shares of  restricted  common stock valued at
     $1.40 per share.  Goodwill in the original  amount of $845,000 was recorded
     and is amortized over ten years.

     On December 30, 1998 the Agreement  with Gulfport was amended to reduce the
     shares of restricted stock to 240,000 and cash that was payable in December
     1998 to $30,000.
     Accordingly, goodwill was reduced by $304,000.

     Gulfport  is a  Mississippi-based  provider of  software  applications  and
     service solutions to the marine industry. The acquisition was accounted for
     as a purchase.  Accordingly,  the assets and  liabilities  of Gulfport  are
     included in the  consolidated  balance  sheet as of December 31, 1997.  The
     results  of  Gulfport's  operations  from  the date of the  acquisition  to
     December 31, 1997 were not significant.

               Total                      $1,029,127

6.   NOTES PAYABLE

     In connection  with the acquisition of Enerdyne on July 7, 1998 (see Note 2
     Acquisitions),  the Company issued two notes payable in the total amount of
     $10,000,000 to or on behalf of the previous owners.  Notes in the amount of
     $8,000,000 are senior  promissory notes payable on July 7, 1999 and bearing
     interest  at 8.5% per annum.  The other notes are  subordinated  promissory
     notes in the amount of $2,000,000  with specified  minimum annual  payments
     and any  remaining  amounts  payable June 30, 2002 and bearing  interest at
     8.5% per annum.

     On December 29, 1998,  the Company  entered into a five year loan agreement
     with a bank  for  $4,250,000  at a  variable  interest  rate  based  on the
     lender's prime rate.  The initial rate at December 29, 1998 was 7.75%.  The
     proceeds were used to pay a portion of the $8,000,000  loan to the previous
     Enerdyne  owners.  The loan is  collaterized  by the stock of the Company's
     subsidiaries (Boatracs Europe,  OceanTrac,  Inc. and Enerdyne Technologies,
     Inc.), as well as the Company's inventory,  accounts,  equipment,  fixtures
     and other  goods.  The terms for the  remaining  balances on the notes were
     amended so that they expire on January 1, 2004.

     On December 29, 1998, the Company  entered into a line of credit  agreement
     with the bank to borrow up to  $750,000  at an  interest  rate equal to the
     lender's  prime rate which was 7.75% on December  29, 1998.  The  agreement
     expires on December 29, 2000. At December 31, 1998 there were no borrowings
     on the line of credit.

7.    INCOME TAXES

    Due to a valuation allowance provided for deferred income tax assets for the
    years ended  December 31, 1997 and 1996,  there was no income tax expense or
    benefit and the Company's effective income tax rate was 0%.

    The tax effects of significant  temporary differences that comprise deferred
tax balances are as follows:

8.   STOCKHOLDERS' EQUITY

     Note  Receivable  Issued for Common Stock - During March 1995,  the Company
     issued  1,112,265  shares of common stock to Qualcomm (see Note 9 - Related
     Party Transactions) for $737,000. The purchase price of the shares was paid
     by a reduction  in the price of certain  products  and  services  currently
     provided  by  Qualcomm to the Company  and,  upon  satisfaction  of certain
     conditions,  the  conversion  of a certain  non-exclusive  territory  to an
     exclusive territory,  under a license and distribution  agreement (see Note
     10 License and Distribution  Agreement).  The transaction was recorded as a
     note  receivable  for common stock issued which is reduced as discounts are
     earned.  Through  December 31,  1998, a total of $737,000 in discounts  had
     been earned and the balance of the note receivable eliminated.

     In October 1997, the company issued  2,900,000 shares of common stock to an
     individual who subsequently became an officer/director of the company, at a
     discounted  rate of $0.80 per share pursuant to the terms of the Restricted
     Stock  Purchase  Agreement.  In  connection  with the  shares,  the Company
     received  a  promissory  note in the  amount of  $1,930,915  bearing  5.77%
     interest. The note required payments of $420,240 on April 15 and October 15
     of each year  commencing  in 1998 with the final  payment  due on April 15,
     2000.  The note had been  recorded as a reduction  of equity on the balance
     sheet.  During 1998,  the note and accrued  interest  were  purchased by an
     outside  party at a discount of $44,274,  which was recorded as a reduction
     of the common stock originally issued.

     In July 1998,  the  Company  issued a total of  3,000,000  shares of common
     stock to the selling  shareholders and their investment bankers of Enerdyne
     valued at $3.17 pursuant to an Agreement and Plan of Reorganization.

     Stock  Warrants - During  October  1995,  the Company  issued 25,000 common
     stock purchase  warrants.  The warrants represent the right to purchase one
     share of the  Company's  common  stock at $1.50 and expire  during  October
     1998. In 1998, the warrants were exercised.

     In April 1998,  the Company issued 30,000  warrants to a consultant,  at an
     exercise price of $1.50 per share.

     In June 1998,  the Company  issued  warrants to purchase  25,000  shares of
     common  stock at $4.44  per  share to a third  party in  connection  with a
     purchase of a promissory note from a director and officer of the Company.

     In July 1998,  the Company  issued  warrants to purchase  500,000 shares of
     common stock at $2.00 per share to the selling shareholders of Enerdyne and
     their investment bankers.

     Stock  Options  -  During  January  1996,   the  Company   entered  into  a
     Non-Circumvention  Agreement  with a financial  consultant.  The  agreement
     included  a grant  of  50,000  stock  options  at $1.50  each.  There is no
     expiration  date on the agreement,  however the agreement may be terminated
     by the company at will.

     In July,  1998, the Company issued options to purchase  1,000,000 shares of
     common  stock to the two  selling  shareholders  of  Enerdyne  at $2.00 per
     share. Pursuant to an amendment to the agreement, the options were adjusted
     to a total of 1,327,000 options at $2.65 each.

     Registration  Statements  with the  Securities  and  Exchange  Commission -
     During 1995, the Company filed two registration statements on Form S-1 with
     the  Securities and Exchange  Commission,  registering a total of 6,049,684
     shares of the  Company's  common  stock.  The  Company  did not receive any
     proceeds from this transaction.

     During May 1996,  the Company filed  Post-Effective  Amendment No. 3 to its
     Form S-1, which provides for  registration of 6,033,385 shares on behalf of
     certain selling stockholders. The Company did not receive any proceeds from
     this transaction.

     During May, 1997,  the Company filed a registration  statement on Form SB-2
     that  provides for  registration  of 5,490,956  shares on behalf of selling
     stockholders.   The  Company  did  not  receive  any  proceeds   from  this
     transaction.

     During April 1998, the Company filed a registration  statement on Form SB-2
     that  provides for  registration  of 9,900,070  shares on behalf of selling
     shareholders.   The  Company  did  not  receive  any  proceeds   from  this
     transaction.  The registration statement,  which is not yet effective,  has
     been refiled for final acceptance by the Commission.

     Stock Option Plan - Under the amended 1996 Stock Option Plan ("the  Plan"),
     the Company may grant incentive and non-qualified options to purchase up to
     2,000,000 shares of common stock to employees, directors and consultants at
     prices that are not less than 100% (85% for  non-qualified)  of fair market
     value on the date the options are  granted.  Options  issued under the Plan
     expire  seven years after the  options  are  granted and  generally  become
     exercisable  ratably over a five-year  period  following the date of grant.
     Stock option transactions are summarized below:

     The  Company  applies  Accounting  Principles  Board  of  Opinion  No.  25,
     "Accounting for Stock Issued to Employees," and related  interpretations in
     accounting  for its Plan.  Accordingly,  no  compensation  expense has been
     recognized for its stock-based  compensation  plan. Had  compensation  cost
     been  determined  based  upon the fair  value at the grant  date for awards
     under the Plan consistent with the methodology  prescribed  under Statement
     of Financial  Accounting  Standards No. 123,  "Accounting  for  Stock-Based
     Compensation,"  the Company's net income for the period ended  December 31,
     1998 would have been reduced by  approximately  $541,000 and the  Company's
     net loss for the years  ended  December  31,  1997 and 1996 would have been
     increased by $73,000 and $33,000 for each of the two years, respectively.

     Under  FASB 123,  the fair  value of the  options  granted  during  1998 is
     estimated  as  approximately  $2,258,000  on the  date of grant  using  the
     Black-Scholes  option-pricing  model  with the  following  assumptions:  no
     dividend yield,  expected  volatility of 236%,  risk-free  interest rate of
     5.1%, and an expected average life of 6.7 years.

9.    RELATED PARTY TRANSACTIONS

     On October 15, 1997,  Company received a promissory note from an individual
     who subsequently became an officer, director and shareholder of the Company
     in the amount of $1,930,915 bearing a rate of 5.77%. The note was issued in
     connection with a Restricted Stock Purchase  Agreement of the same date for
     a total of  2,900,000  shares  of the  Company's  stock  (see Note 8 - Note
     Receivable Issued for Common Stock). The shares were issued at a discounted
     rate of $0.80 per share based on the  restrictions  of the  agreement.  The
     note called for semi annual  installments  with the final  payment on April
     15, 2000. During June 1998, the note and accrued interest were purchased by
     an  outside  party at a  discount  of  $44,274,  which  was  recorded  as a
     reeduction of the common stock originally issued.

10.  LICENSE AND DISTRIBUTION AGREEMENT

     During 1990, the Company entered into a license and distribution agreement,
     as amended through June 25, 1997, with QUALCOMM. Pursuant to the agreement,
     the  Company  was  appointed   QUALCOMM'S   exclusive   and   non-exclusive
     distributor,  in  defined  territories,  of the  OmniTRACS  satellite-based
     communications and tracking system (the "System") for marine  applications.
     During  1996,  the  Company  reached  certain  sales  goals and  became the
     exclusive distributor in previously non-exclusive territories.  The Company
     was also appointed provider of message services to the users of the System.
     In  connection  therewith,  the Company was also granted an  exclusive  and
     non-exclusive  license to certain  software used with the System.  QUALCOMM
     was granted an exclusive perpetual,  worldwide, royalty free license to any
     improvements made by the Company to the System or related software.

     Under the  agreement,  the Company is  required  to sell a certain  minimum
     number of systems in order to maintain the exclusivity of its  distribution
     rights.  The minimum purchase  requirements for each calendar year is to be
     agreed upon  between the Company and  QUALCOMM  subject to a minimum of 300
     systems for calendar  year ended  December 31, 1997 and  increasing  by 10%
     each year  thereafter.  The Company met this  requirement in 1998, 1997 and
     1996.

     If  QUALCOMM  is  unable to  provide  service  or  elects  not to remain in
     business, they may terminate the agreement with six months' notice and have
     no further liability.  QUALCOMM shall take such steps, which are reasonable
     and  necessary  to enable the  Company to  continue  to provide the message
     services to its existing end users.

     The  agreement  expires  during  June  2000  and  may be  renewed  for  two
     additional five-year periods. The agreement is subject to re-negotiation at
     the end of the option period.

     Sub-service  Provider  Agreement - During 1997, the Company  entered into a
     Sub-service  Provider  Agreement with ALCATEL  Qualcomm,  a French company,
     whereby the Company will provide  maritime  satellite-based  communications
     and tracking of vessels to certain countries in Europe.

11.  SALARY REDUCTION SIMPLIFIED EMPLOYER PLAN (SAR-SEP)

     During  September  1996,  the  Company  approved  the  adoption of a Salary
     Reduction Simplified Employer Plan (SAR-SEP) allowing eligible employees to
     contribute savings on a pretax basis effective January 1996. Employees were
     able  to  contribute  up to 15% of  their  salary,  not  to  exceed  $9,500
     annually.  A  discretionary  contribution  is  determined  each year by the
     Company.  In 1998 and 1997,  the Company did not elect to contribute to the
     Plan, and the Plan was terminated in 1998.

12.   GEOGRAPHIC AND BUSINESS SEGMENT INFORMATION

     The Company operates what management believes to be two reportable business
     segments:  Communications and Video Compression.  The Company's  reportable
     segments are strategic  business  units that offer  different  products and
     services.  They are managed separately based on fundamental  differences in
     their operations.

     The  Communications  segment consists of the operations of Boatracs,  Inc.,
     Boatracs  (Europe) B.V. and Oceantracs,  Inc., as well as the operations of
     MED. The Communications  segment has exclusive  distribution  rights in the
     United  States  for  marine   application   of  the  OmniTRACS   system  of
     satellite-based   communication   and  tracking  systems   manufactured  by
     QUALCOMM.  In addition,  the Company's wholly owned subsidiaries,  Boatracs
     (Europe)  B.V.  and  Oceantracs,   Inc.  have  agreements  with  QUALCOMM'S
     authorized  service providers in Europe and Canade for marine  distribution
     of OmniTRACS  in parts of Europe and Canada.  MED is a provider of software
     applications  and  service  solutions  to  the  commercial  work  boat  and
     petroleum industries, including customers of Boatracs.

     The Video Compression  segment consists of the operations of Enerdyne which
     the Company acquired in July 1998 (see Note 2 - Acquisitions).  Enerdyne is
     a  provider  of  versatile,  high  performance  digital  video  compression
     products to the government and commercial markets.

     In 1997 and 1996 there was only one segment, communications.

conditions precedent, with all documents,  instruments,  opinions,  reports, and
other  items  required  under  this  Agreement  to  be  in  form  and  substance

 (f) Borrower shall have paid to Lender all fees, costs, and expenses  specified

Making Loan Advances.  Advances under the Line of Credit may be requested either
orally or in writing by authorized  persons.  Lender may, but need not,  require
that  all  oral  requests  be  confirmed  in  writing.  Each  Advance  shall  be
conclusively  deemed to have been made at the  request of and for the benefit of
Borrower (a) when credited to any deposit  account of Borrower  maintained  with
Lender or (b) when advanced in accordance with the instructions of an authorized
person.  Lender, at its option,  may set a cutoff time, after which all requests

outstanding  Advances  shall exceed the  applicable  Borrowing  Base,  Borrower,
immediately upon written notice from Lender, shall pay to Lender an amount equal
to the difference between the outstanding  principal balance of the Advances and
the Borrowing Base. On the Expiration Date, Borrower shall pay to Lender in full
the aggregate  unpaid  principal amount of all Advances then outstanding and all
accrued unpaid  interest,  together with all other  applicable  fees,  costs and
charges, if any, not yet paid.

Lender  shall make entries for each Advance and such other debits and credits as
shall be  appropriate  in  connection  with the credit  facility.  Lender  shall
provide Borrower with monthly statements of Borrower's account, which statements
shall be considered to be correct and  conclusively  binding on Borrower  unless
Borrower  notifies  Lender  to  the  contrary  within  thirty  (30)  days  after
Borrower's receipt of any such statement, which Borrower deems to be incorrect.

COLLATERAL. To secure payment of the Line of Credit and performance of all other
Loans,  obligations and duties owed by Borrower to Lender, Borrower (and others,
if  required)  shall grant to Lender  Security  Interests  in such  property and
assets as Lender may require (the  "Collateral"),  including without  limitation

Lender's  Security  Interests in the  Collateral  shall be continuing  liens and

limitation  the  proceeds  of any  insurance.  With  respect to the  Collateral,
Borrower agrees and represents and warrants to Lender:

as a financing  statement.  Borrower will reimburse  Lender for all expenses for
the perfection,  termination, and the continuation of the perfection of Lender's
security interest in the Collateral. Borrower promptly will notify Lender of any
change in Borrower's name including any change to the assumed  business names of
Borrower.  Borrower also promptly will notify Lender of any change in Borrower's
Social  Security  Number or Employer  Identification  Number.  Borrower  further
agrees to notify Lender in writing prior to any change in address or location of
Borrower's  principal  governance office or should Borrower merge or consolidate
with any other entity.

binding upon Borrower or (b) any law, governmental regulation,  court decree, or
order applicable to Borrower.

the  statement,  and there has been no  material  adverse  change in  Borrower's
financial  condition  subsequent  to the  date  of  the  most  recent  financial
statement supplied to Lender.  Borrower has no material  contingent  obligations
except as disclosed in such financial statements.

and Borrower has not used, or filed a financing  statement under, any other name
for at least the last five (5) years.

Hazardous  Substances.  The  terms  "hazardous  waste,"  "hazardous  substance,"

shall have the same meanings as set forth in the "CERCLA," "SARA," the Hazardous
Materials  Transportation  Act, 49 U.S.C.  Section 1801,  et seq.,  the Resource

through 7.7 of Division 20 of the  California  Health and Safety  Code,  Section
25100, et seq., or other applicable state or Federal laws, rules, or regulations
adopted  pursuant  to  any  of  the  foregoing.   Except  as  disclosed  to  and
acknowledged  by Lender in writing,  Borrower  represents and warrants that: (a)
During the period of Borrower's  ownership of the properties,  there has been no
use,  generation,   manufacture,   storage,  treatment,   disposal,  release  or
threatened  release of any hazardous waste or substance by any person on, under,
about or from any of the properties. (b) Borrower has no knowledge of, or reason
to believe that there has been (i) any use,  generation,  manufacture,  storage,
treatment,  disposal,  release,  or threatened release of any hazardous waste or
substance  on,  under,  about or from the  properties  by any  prior  owners  or
occupants of any of the properties,  or (ii) any actual or threatened litigation
or  claims of any kind by any  person  relating  to such  matters.  (c)  Neither
Borrower nor any tenant,  contractor,  agent or other  authorized user of any of
the properties shall use, generate,  manufacture,  store, treat,  dispose of, or
release any hazardous  waste or substance  on,  under,  about or from any of the
properties;  and any such  activity  shall be conducted in  compliance  with all
applicable  federal,  state,  and  local  laws,  regulations,   and  ordinances,
including without  limitation those laws,  regulations and ordinances  described
above. Borrower authorizes Lender and its agents to enter upon the properties to
make such  inspections  and tests as Lender may deem  appropriate  to  determine
compliance of the properties with this section of the Agreement. Any inspections
or tests made by Lender shall be at Borrower's expense and for Lender's purposes
only and shall not be construed to create any responsibility or liability on the
part of Lender to  Borrower  or to any other  person.  The  representations  and
warranties   contained   herein  are  based  on  Borrower's   due  diligence  in
investigating  the  properties  for hazardous  waste and  hazardous  substances.
Borrower  hereby (a) releases and waives any future  claims  against  Lender for
indemnity or  contribution  in the event Borrower  becomes liable for cleanup or
other costs under any such laws,  and (b) agrees to indemnify  and hold harmless
Lender against any and all claims, losses, liabilities,  damages, penalties, and
expenses  which Lender may directly or  indirectly  sustain or suffer  resulting
from a breach of this section of the Agreement or as a  consequence  of any use,
generation,  manufacture,  storage, disposal, release or threatened release of a
hazardous waste or substance on the  properties.  The provisions of this section
of the  Agreement,  including the  obligation  to  indemnify,  shall survive the
payment of the  Indebtedness and the termination or expiration of this Agreement
and shall not be affected by Lender's  acquisition of any interest in any of the
properties, whether by foreclosure or otherwise.

Litigation  and Claims.  No  litigation,  claim,  investigation,  administrative
proceeding or similar action (including those for unpaid taxes) against Borrower
is pending or to the best of Borrower's knowledge,  threatened,  and to the best

adversely  affect  Borrower's  financial  condition  or  properties,  other than
litigation,  claims,  or other events,  if any, that have been  disclosed to and
acknowledged by Lender in writing.

Borrower that are or were required to be filed,  have been filed, and all taxes,

presently  being or to be  contested  by Borrower in good faith in the  ordinary
course of business and for which adequate reserves have been provided.

Borrower has not entered into or granted any Security  Agreements,  or permitted
the filing or  attachment  of any Security  Interests on or affecting any of the
Collateral  directly or indirectly  securing  repayment of  Borrower's  Loan and
Note,  that  would  be  prior or that  may in any way be  superior  to  Lender's
Security Interests and rights in and to such Collateral.

Binding Effect.  This Agreement,  the Note, all Security  Agreements directly or
indirectly securing repayment of Borrower's Loan and Note and all of the Related
Documents  are  binding  upon  Borrower as well as upon  Borrower's  successors,
representatives  and assigns,  and are legally  enforceable  in accordance  with
their respective terms.

Commercial Purposes.  Borrower intends to use the Loan proceeds solely fo
 business or commercial related purposes.

upon  any of  Borrower's  properties,  income,  or  profits.  Provided  however,
Borrower  will not be required to pay and discharge  any such  assessment,  tax,
charge,  levy,  lien or claim so long as (a) the  legality  of the same shall be
contested in good faith by appropriate proceedings,  and (b) Borrower shall have
established  on its books  adequate  reserves  with  respect  to such  contested

Borrower now or at any time hereafter  maintains any records  (including without
limitation  computer  generated  records and computer  software programs for the
generation of such records) in the possession of a third party,  Borrower,  upon
request of Lender,  shall notify such party to permit Lender free access to such
records at all reasonable times and to provide Lender with copies of any records

environmental activity is pursuant to and in compliance with the conditions of a
permit  issued  by  the  appropriate   federal,   state  or  local  governmental
authorities;  shall  furnish to Lender  promptly and in any event within  thirty
(30) days after receipt thereof a copy of any notice,  summons,  lien, citation,

there is damage to the environment and/or other natural resources.

Additional  Assurances.  Make,  execute and  deliver to Lender  such  promissory
notes,  mortgages,  deeds of trust,  security agreements,  financing statements,
instruments,  documents  and other  agreements  as Lender or its  attorneys  may

Interests on terms set forth on this Agreement or Related Documents.



RECOVERY OF  ADDITIONAL  COSTS.  If the  imposition of or any change in any law,
rule,  regulation or guideline,  or the  interpretation  or  application  of any

other  obligations  which would (a) increase the cost to Lender for extending or
maintaining the credit  facilities to which this Agreement  relates,  (b) reduce

compensate  Lender therefor,  within five (5) days after Lender's written demand
for such payment,  which demand shall be  accompanied  by an explanation of such
imposition or charge and a calculation  in reasonable  detail of the  additional
amounts  payable  by  Borrower,  which  explanation  and  calculations  shall be
conclusive in the absence of manifest error.



NEGATIVE COVENANTS. Borrower and Guarantors in the aggregate, covenant and agree
with Lender that while this  Agreement  is in effect,  Borrower  and  Guarantors
shall not, without the prior written consent of Lender:



Indebtedness  and Liens. (a) Except for trade debt incurred in the normal course
of business and indebtedness to Lender  contemplated by this Agreement,  create,
incur or assume  additional  indebtedness for borrowed money,  including capital
leases,  in excess of the aggregate  amount of U.S.  $200,000.00,  (b) except as

Borrower's stock (other than dividends payable in its stock), provided,  however

occurred and is  continuing  or would result from the payment of  dividends,  if
Borrower is a "Subchapter  S  Corporation"  (as defined in the Internal  Revenue
Code of 1986, as amended),  Borrower may pay cash  dividends on its stock to its
shareholders  from time to time in amounts  necessary to enable the shareholders
to pay income  taxes and make  estimated  income tax  payments to satisfy  their

Agreement or in any of the Related  Documents,  or failure of Borrower to comply
with or to perform any other term,  obligation,  covenant or condition contained

property or Borrower's  or any  Grantor's  ability to repay the Loans or perform
their  respective  obligations  under  this  Agreement  or any  of  the  Related
Documents.

False Statements. Any warranty, representation or statement made or furnished to
Lender by or on behalf of Borrower or any Grantor  under this  Agreement  or the

proceedings,  whether by judicial  proceeding,  self-help,  repossession  or any
other method,  by any creditor of Borrower,  any creditor of any Grantor against
any collateral  securing the Indebtedness,  or by any governmental  agency. This

  financial  condition,  or Lender  believes the prospect of
payment or performance of the Indebtedness is impaired.

Right to Cure. If any default, other than a Default on Indebtedness,  is curable
and if Borrower or Grantor, as the case may be, has not been given a notice of a
similar default within the preceding twelve (12) months, it may be cured (and no
Event of Default will have occurred) if Borrower or Grantor, as the case may be,
after receiving  written notice from Lender demanding cure of such default:  (a)
cures the default  within ten (10) days;  or (b) if the cure  requires more than
ten (10) days,  immediately  initiates steps which Lender deems in Lender's sole

otherwise provided in this Agreement or the Related  Documents,  all commitments
and  obligations of Lender under this Agreement or the Related  Documents or any
other  agreement  immediately  will terminate  (including any obligation to make
Loan  Advances or  disbursements),  and, at Lender's  option,  all  Indebtedness
immediately  will  become due and  payable,  all  without  notice of any kind to
Borrower,  except that in the case of an Event of Default of the type  described
in the "Insolvency"  subsection above, such acceleration  shall be automatic and
not  optional.  In  addition,  Lender  shall have all the  rights  and  remedies
provided in the Related  Documents or available at law, in equity, or otherwise.
Except as may be  prohibited  by  applicable  law,  all of  Lender's  rights and
remedies  shall be cumulative and may be exercised  singularly or  concurrently.
Election by Lender to pursue any remedy  shall not exclude  pursuit of any other
remedy,  and an  election to make  expenditures  or to take action to perform an
obligation  of  Borrower or of any Grantor  shall not affect  Lender's  right to
declare a default and to exercise its rights and remedies.

Agreement shall be joint and several,  and all references to Borrower shall mean
each and every  Borrower.  This means that each of the persons  signing below is
responsible for all obligations in this Agreement.

Consent to Loan Participation.  Borrower agrees and consents to Lender's sale or
transfer,  whether now or later, of one or more  participation  interests in the
Loans to one or more purchasers,  whether related or unrelated to Lender. Lender
may provide,  without any limitation whatsoever,  to any one or more purchasers,
or potential  purchasers,  any  information  or knowledge  Lender may have about
Borrower or about any other matter  relating to the Loan,  and  Borrower  hereby
waives any rights to privacy it may have with respect to such matters.  Borrower
additionally waives any and all notices of sale of participation  interests,  as
well as all notices of any repurchase of such participation interests.  Borrower
also agrees that the  purchasers  of any such  participation  interests  will be
considered as the absolute  owners of such  interests in the Loans and will have
all the rights granted under the participation agreement or agreements governing
the sale of such participation interests.  Borrower further waives all rights of
offset or  counterclaim  that it may have now or later against Lender or against
any purchaser of such a participation  interest and unconditionally  agrees that
either Lender or such  purchaser  may enforce  Borrower's  obligation  under the
Loans irrespective of the failure or insolvency of any holder of any interest in
the Loans.  Borrower further agrees that the purchaser of any such participation
interests  may enforce its  interests  irrespective  of any  personal  claims or
defenses that Borrower may have against Lender.

Costs and Expenses. Borrower agrees to pay upon demand all of Lender's expenses,
including without  limitation  attorneys' fees,  incurred in connection with the
preparation,  execution,  enforcement,   modification  and  collection  of  this
Agreement  or in  connection  with the Loans made  pursuant  to this  Agreement.

limits  under  applicable  law,  Lender's  attorneys'  fees and  Lender's  legal
expenses,  whether  or not there is a  lawsuit,  including  attorneys'  fees for

recognized  overnight  courier or  deposited in the United  States  mail,  first
class, postage prepaid, addressed to the party to whom the notice is to be given
at the address  shown above.  Any party may change its address for notices under
this Agreement by giving formal written notice to the other parties,  specifying
that the purpose of the notice is to change the party's  address.  To the extent
permitted by applicable  law, if there is more than one Borrower,  notice to any
Borrower will constitute notice to all Borrowers. For notice purposes,  Borrower
will keep Lender informed at all times of Borrower's current address(es).

Agreement to be invalid or unenforceable as to any person or circumstance,  such
finding shall not render that provision invalid or unenforceable as to any other
persons or  circumstances.  If feasible,  any such offending  provision shall be

right to assign its rights under this Agreement or any interest therein, without
the prior written consent of Lender.

Survival.  All  warranties,  representations,  and covenants made by Borrower in
this Agreement or in any certificate or other  instrument  delivered by Borrower
to Lender under this  Agreement  shall be considered to have been relied upon by
Lender and will  survive  the making of the Loan and  delivery  to Lender of the
Related Documents, regardless of any investigation made by Lender or on Lender's
behalf.

Time Is of the Essence.  Time is of the essence in the performance of this 
Agreement.

Waiver.  Lender  shall  not be deemed  to have  waived  any  rights  under  this
Agreement unless such waiver is given in writing and signed by Lender.  No delay
or omission  on the part of Lender in  exercising  any right shall  operate as a
waiver of such right or any other  right.  A waiver by Lender of a provision  of
this  Agreement  shall not  prejudice or  constitute a waiver of Lender's  right
otherwise to demand strict compliance with that provision or any other provision
of this Agreement.  No prior waiver by Lender, nor any course of dealing between
Lender and  Borrower,  or between  Lender and any  Grantor,  shall  constitute a
waiver of any of  Lender's  rights or of any  obligations  of Borrower or of any
Grantor  as to any  future  transactions.  Whenever  the  consent  of  Lender is
required  under this  Agreement,  the  granting of such consent by Lender in any
instance shall not constitute  continuing consent in subsequent  instances where
such  consent  is  required,  and in all cases  such  consent  may be granted or
withheld in the sole discretion of Lender.

Interest not yet paid.  The annual  Interest rate for this Note Is computed on a
365/360 basis;  that is by applying the ratio of the annual Interest rate over a
year of 360 days, multiplied by the outstanding principal balance, multiplied by
the actual number of days the principal  balance Is  outstanding.  Borrower will
pay Lender at Lender's  address shown above or at such other place as Lender may
designate In writing.  Unless  otherwise  agreed or required by applicable  law,
payments  will be  applied  first to any  unpaid  collection  costs and any late
charges, then to any unpaid Interest, and any remaining amount to principal.

VARIABLE INTEREST RATE. The Interest rate on this Note Is subject to change from
time to time based on changes In an Index which Is the Prime Rate (the "Index").
This Is the rate Lender  announces  from time to time as Its Prime  Rate,  which
generally Is the rate Lender charges, or would charge, on 90-day unsecured loans
to the most creditworthy  corporate  customers.  This rate may not be the lowest
rate  available  from Lender at any given time.  Lender will tell  Borrower  the
current Index rate upon Borrower's request. Borrower understands that Lender may
make loans based on other rates as well. The Interest rate change will not occur
more often than each day. The Index currently Is 7.750%. The Interest rate to be
applied to the unpaid principal  balance of this Note will be at a rate equal to
the  Index,   resulting  in  an  Initial  rate  of  7.750%.   NOTICE:  Under  no
circumstances  will the Interest rate on this Note be more than the maximum rate
allowed by applicable law.

PREPAYMENT;  MINIMUM  INTEREST  CHARGE.  Borrower  agrees that all loan fees and
other  prepaid  finance  charges are earned fully as of the date of the loan and
will not be subject to refund  upon early  payment  (whither  voluntary  or as a
result of default), except as otherwise required by law. In any event, even upon
full prepayment of this Note, Borrower  understands that Lender Is entitled to a
minimum interest charge of $100.00.  Other than Borrower's obligation to pay any
minimum  Interest  charge,  Borrower may pay without penalty all or a portion of
the amount owed earlier than It is due. Early  payments will not,  unless agreed
to by Lender In writing,  relieve Borrower of Borrower's  obligation to continue
to make  payments  under the  payment  schedule.  Rather,  they will  reduce the
principal balance due and may result In Borrower making fewer payments.

LATE  CHARGE.  If a payment  Is 10 days or more late,  Borrower  will be charged
5.000% of the  unpaid  portion  of the  regularly  scheduled  payment or $10.00,
whichever Is greater.

DEFAULT.  Borrower  will be In  default  If any of the  following  happens:  (a)
Borrower  falls to make any payment when due within  five(5)days of the original
due date(b) Borrower breaks any promise Borrower has made to Lender, or Borrower
falls  to  comply  with or to  perform  when  due any  other  term,  obligation,
covenant,  or condition  contained In this Note or any agreement related to this
Note, or In any other  agreement or loan Borrower has with Lender.  (c) Borrower
defaults under any loan.  extension of credit,  security agreement,  purchase or
sales  agreement,  or any  other  agreement,  for  money  borrowed  in excess of
$50,000.00,  in favor of any other creditor or person that may materially affect
any of Borrower's  property or Borrower's  ability to repay this Note or perform
Borrower's obligations under this Note or any of the Related Documents.  (d) Any
representation  or  statement  made or  furnished  to Lender by  Borrower  or on
Borrower's  behalf Is false or misleading In any material  respect either now or
at the time  made or  furnished.  Borrower  becomes  insolvent,  a  receiver  is
appointed for any part of Borrower's properly,  Borrower makes an assignment for
the benefit of creditors,  or any proceeding Is commenced  either by Borrower or
against  Borrower under any bankruptcy or Insolvency laws continued in paragraph
entitled "additional  Provision" (f)Any creditor tries to take any of Borrower's
properly on or In which Lender has a lien or security Interest.  This Includes a
garnishment of any of Borrower's accounts with Lender. (g) Any guarantor dies or
any of the other events described In this default section occurs with respect to
any grantor of this Note.  (h) A material  adverse  change  occurs In Borrower's
financial  condition,  or Lender reasonably  believes the prospect of payment or
performance  of the  Indebtedness  Is  Impaired.  If any  default,  other than a
default in payment,  is curable and if Borrower has not been given a notice of a
breach of the same provision of this Note within the preceding twelve(12)months,
it may be cured (and no event of default will have occurred) if Borrower,  after
receiving written notice from Lender demanding cure of such default:(a)cures the
default within ten (10) days; or(b)If the cure requires more than ten (10) days,
immediately initiates steps which Lender deems in Lender's sole discretion to be

final maturity,  Lender, at Its option,  may also, if permitted under applicable
law, Increase the variable Interest rate on this Note to 5.000 percentage points
over the Index. Lender may hire or pay someone else to help collect this Note If

to the most creditworthy  corporate  customers.  This rate may not be the lowest

minimum  interest  charge,  Borrower may pay without penalty all or a portion of
the amount owed earlier than it is due. Early  payments will not,  unless agreed
to by Lender in writing,  relieve Borrower of Borrower's  obligation to continue
to make  payments  of accrued  unpaid  Interest.  Rather,  they will  reduce the
principal balance due.

580a.

Grantor  understands  and  agrees  that the  foregoing  waivers  are  waivers of
substantive  rights and defenses to which  Grantor  might  otherwise be entitled
under slate and federal  law. The rights and defenses  waived  include,  without
limitation,  those  provided by  California  laws of  suretyship  and  guaranty,
anti-deficiency laws, and the Uniform Commercial Code. Grantor acknowledges that
Grantor has provided  these  waivers of rights and defenses  with the  intention
that they be fully  relied  upon by Lender.  Until all  Indebtedness  is paid In
full,  Grantor  waives any right to enforce any remedy  Lender may have  against
Borrower or any other guarantor,  surety, or other person, and further,  Grantor
waives any right to participate in any  collateral for the  Indebtedness  now or
hereafter held by Lender.

If now or  hereafter  (a)  Borrower  shall be or become  insolvent,  and (b) the
Indebtedness  shall not at all times until paid be fully  secured by  collateral
pledged by Borrower,  Grantor hereby forever waives and relinquishes In favor of
Lender and  Borrower,  and their  respective  successors,  any claim or right to
payment Grantor may now have or hereafter have or acquire against  Borrower,  by

market,  Lender shall give or mail to Grantor,  or any of them,  notice at least
ten (10) days In  advance of the time and place of any  public  sale,  or of the
date  after  which  any  private  sale  may be  made.  Grantor  agrees  that any

Code of Civil Procedure Section 580a.

Grantor  understands  and  agrees  that the  foregoing  waivers  are  waivers of
substantive  rights and defenses to which  Grantor  might  otherwise be entitled
under state and federal  law. The rights and defenses  waived  Include,  without
limitation,  those  provided by  California  laws of  suretyship  and  guaranty,
anti-deficiency laws, and the Uniform Commercial Code. Grantor acknowledges that
Grantor has provided  these  waivers of rights and defenses  with the  intention
that they be fully  relied  upon by Lender.  Until all  Indebtedness  Is paid In
full,  Grantor  waives any right to enforce any remedy  Lender may have  against
Borrower or any other guarantor,  surety, or other person, and further,  Grantor
waives any right to participate in any  collateral for the  Indebtedness  now or
hereafter held by Lender.

If now or  hereafter  (a)  Borrower  shall be or become  insolvent,  and (b) the
Indebtedness  shall not at all times until paid be fully  secured by  collateral
pledged by Borrower,  Grantor hereby forever waives and relinquishes In favor of
Lender and  Borrower,  and their  respective  successors,  any claim or right to
payment Grantor may now have or hereafter have or acquire against  Borrower,  by
subrogation  or  otherwise,  so that at no time  shall  Grantor  be or  become a

ten (10) days' prior written  notice to Lender and not Including any  disclaimer
of the  insurer's  liability for failure to give such a notice.  Each  Insurance
policy also shall  Include an  endorsement  providing  that coverage In favor of
Lender  will not be  Impaired  In any way by any act,  omission  or  default  of
Grantor or any other person.  In connection with all policies covering assets In
which  Lender  holds or is offered a security  Interest,  Grantor  will  provide
Lender with such loss payable or other  endorsements  as Lender may require.  If
Grantor at any time falls to obtain or maintain any Insurance as required  under
this Agreement, Lender may (but shall not be obligated to) obtain such Insurance
as  Lender  deems  appropriate,  Including  If It so  chooses  "single  interest
insurance," which will cover only Lender's Interest In the Collateral.

Application of Insurance Proceeds. Grantor shall promptly notify Lender of any
material  loss or damage to the  Collateral.  Lender  may make  proof of loss If
Grantor falls to do so within fifteen (15) days of the casualty. All proceeds of
any  Insurance  on a  material  portion  of the  Collateral,  Including  accrued
proceeds thereon,  shall be held by Lender as part of the Collateral.  If Lender
consents to repair or replacement of the damaged or destroyed Collateral, Lender
shall, upon satisfactory proof of expenditure, pay or reimburse Grantor from the
proceeds for the reasonable  cost of repair or  restoration.  If Lender does not
consent  to repair or  replacement  of the  Collateral,  Lender  shall  retain a
sufficient amount of the proceeds to pay all of the Indebtedness,  and shall pay
the balance to Grantor.  Any proceeds which have not been  disbursed  within six
(6) months after their receipt and which Grantor has not committed to the repair
or  restoration  of the  Collateral  shall be used to prepay  the  Indebtedness.
Insurance Reserves. Following an event of default, Lender may require Grantor to
maintain with Lender reserves for payment of Insurance premiums,  which reserves
shall be created by monthly  payments  from Grantor of a sum estimated by Lender
to be sufficient  to produce,  at least fifteen (15) days before the premium due
date,  amounts at least equal to the  insurance  premiums to be paid. If fifteen
(15) days before  payment Is due, the reserve  funds are  Insufficient,  Grantor
shall upon demand pay any deficiency to Lender.  The reserve funds shall be hold
by Lender as a general  deposit  and  shall  constitute  a  non-interest-bearing
account which Lender may satisfy by payment of the Insurance  premiums  required
to be paid by Grantor as they become due. Lender does not hold the reserve funds
In trust for Grantor,  and Lender Is not the agent of Grantor for payment of the
insurance  premiums required to be paid by Grantor.  The  responsibility for the
payment of  premiums  shall  remain  Grantor's  sole  responsibility.  Insurance
Reports.  Grantor,  upon request of Lender,  shall furnish to Lender  reports on
each  existing  policy of  Insurance  showing  such  Information  as Lender  may
reasonably request Including the following: (a) the name of the Insurer; (b) the
risks Insured;  (c) the amount of the policy; (d) the property Insured;  (e) the
then current  value on the basis of which  Insurance  has been  obtained and the
manner of determining that value; and (f) the expiration date of the policy.  In
addition,  Grantor  shall upon  request by Lender  (however  not more often than
annually) have an Independent  appraiser  satisfactory to Lender  determine,  as
applicable, the cash value or replacement cost of the Collateral.

GRANTOR'S RIGHT TO POSSESSION. Until default, Grantor may have possession of the
tangible  personal property and beneficial use of all the Collateral and may use
It In any lawful  manner not  Inconsistent  with this  Agreement  or the Related
Documents,  provided that Grantor's right to possession and beneficial use shall
not apply to any  Collateral  where  possession  of the  Collateral by Lender is
required by law to perfect Lender's  security  Interest In such  Collateral.  If
Lender at any time has possession of any Collateral,  whether before or after an
Event of Default,  Lender shall be deemed to have exercised  reasonable  care In
the custody and  preservation  of the Collateral If Lender takes such action for
that purpose as Grantor shall request or as Lender, In Lender's sole discretion,
shall doom appropriate under the circumstances, but failure to honor any request
by Grantor shall not of itself be deemed to be a failure to exercise  reasonable
care.  Lender shall not be required to take any steps  necessary to preserve any
rights In the  Collateral  against prior  parties,  nor to protect,  preserve or
maintain any security Interest given to secure the Indebtedness.

EXPENDITURES  BY LENDER.  If not  discharged or paid when due,  Lender may. (but
shall  not  be  obligated  to)  discharge  or pay  any  amounts  required  to be
discharged or paid by Grantor under this Agreement, Including without limitation
all taxes,  liens,  security Interests,  encumbrances,  and other claims, at any
time  levied or  placed on the  Collateral.  Lender  also may (but  shall not be
obligated  to) pay all  costs  for  Insuring,  maintaining  and  preserving  the
Collateral.  All such expenditures  Incurred or paid by Lender for such purposes
will  then  bear  interest  at the rate  charged  under  the Note  from the date
Incurred  or paid by  Lender  to the  date of  repayment  by  Grantor.  All such
expenses shall become a part of the Indebtedness  and, at Lender's option,  will
(a) be  payable  on  demand,  (b) be  added  to the  balance  of the Note and be
apportioned  among and be payable  with any  Installment  payments to become due
during  either  (i) the  term of any  applicable  Insurance  policy  or (ii) the
remaining term of the Note, or (c) be treated as a balloon payment which will be
due and payable at the Note's maturity.  This Agreement also will secure payment
of these  amounts.  Such  right  shall be In  addition  to all other  rights and
remedies to which  Lender may be  entitled  upon the  occurrence  of an Event of
Default.

EVENTS OF DEFAULT Each of the  following  shall  constitute  an Event of Default
under this Agreement:

Default on  Indebtedness.  Failure of Borrower to make any payments  within Five
days  following the date due on the  indebtedness.  Other  Defaults.  Failure of
Grantor or Borrower  to comply  with or to perform  any other term,  obligation,
covenant  or  condition  contained  In this  Agreement  or In any of the Related
Documents  or  failure  of  Borrower  to  comply  with or to  perform  any term,
obligation,  covenant or  condition  contained  In any other  agreement  between
Lender and Borrower.

Default In Favor of Third Parties.  Should Borrower or any Grantor default under
any loan, extension of credit, security agreement,  purchase or sales agreement,
or any other agreement, for money borrowed in excess of $50,000.00,  in favor of
any other  creditor  or person  that may  materially  affect  any of  Borrower's
property or Borrower's  or any  Grantor's  ability to repay the Loans or perform
their respective obligations under this Agreement or any of the Related
Documents.

False Statements. Any warranty, representation or statement made or furnished to
Lender by or on behalf of Grantor or Borrower under this Agreement,  the Note or
the Related Documents Is false or misleading In any material respect, either now
or at the time made or furnished.

Detective  Collateralization.  This  Agreement  or any of the Related  Documents
ceases to be in full  force and  effect  (including  failure  of any  collateral
documents to create a valid and perfected security Interest or lien) at any time
and for any reason.  Insolvency  continued  in  paragraph  entitled  "Additional
Provision". The dissolution or termination of Grantor or Borrower's existence as
a going  business,  the Insolvency of Grantor or Borrower,  the appointment of a
receiver for any part of Grantor or Borrower's property,  any assignment for the
benefit of creditors,  any type of creditor workout,  or the commencement of any
proceeding  under any  bankruptcy  or Insolvency  laws by or against  Grantor or
Borrower.

Creditor or Forfeiture  Proceedings.  Commencement  of foreclosure or forfeiture
proceedings,  whether by Judicial  proceeding,  self-help,  repossession  or any
other  method,  by any  creditor of Grantor or  Borrower or by any  governmental
agency against the Collateral or any other collateral securing the Indebtedness.
This Includes a garnishment  of any of Grantor or  Borrower's  deposit  accounts
with Lender.  However,  this Event of Default shall not apply If there Is a good
faith dispute by Grantor or Borrower as to the validity or reasonableness of the
claim which is the basis of the creditor or forfeiture proceeding and If Grantor
or Borrower gives Lender written notice of the creditor or forfeiture proceeding
and deposits  with Lender monies or a surety bond for the creditor or forfeiture
proceeding,  in an amount determined by Lender, in its sole discretion, as being
an adequate reserve or bond for the dispute.

Events Affecting  Guarantor.  Any of the preceding events occurs with respect to
any  `guarantor of any of the  indebtedness  or such  Guarantor  dies or becomes
incompetent.  Lender,  at its option,  may, but shall not be required to, permit
the Guarantor's estate to assume  unconditionally  the obligations arising under
the guaranty in a manner satisfactory to Lender, and, in doing so, cure the

Event of Default.
Adverse  Change.  A  Material  adverse  change  occurs in  Borrower's  financial
condition,  or Lender reasonable believes the prospect of payment or performance
of the  indebtedness  is impaired.  Right to Cure. If any default,  other than a
Default on  indebtedness,  is curable  and if Grantor or  Borrower  has not been
given a prior notice of a breach of the same provision of the Agreement,  it may
be cured (and no Event of Default will have  occurred) if Grantor or  `Borrower,
after Lender sends written notice demanding cure of such default,  (a) cures the
default  within ten (10) days;  or (b) if the cure  requires  more than ten (10)
days, immediately initiates steps which Lender deems in Lender's sole discretion
to be sufficient to cure the default and thereafter  continues and completes all
reasonable  and  necessary  steps  sufficient  to produce  compliance as soon as
reasonably practical.

RIGHTS  AND  REMEDIES  ON  DEFULT.  If an Event of  Default  occurs  under  this
Agreement, at any time thereafter, Lender shall have all the rights of a secured
party under the  California  Uniform  Commercial  Code.  In addition and without
limitation,  Lender may  exercise  any one or more of the  following  rights and
remedies:

Accelerate Indebtedness.  Lender may declare the entire indebtedness,  including
any prepayment penalty which Borrower would be required to pay,  immediately due
and payable, without notice.

Assemble Collateral.  Lender may require Grantor to deliver to Lender all or any
portion  of the  Collateral  and any and all  certificates  of title  and  other
documents relating to the Collateral. Lender may require Grantor to assemble the
Collateral  and make It  available  to  Lender  at a place to be  designated  by
Lender.  Lender also shall have full power to enter upon the property of Grantor
to take  possession of and remove the  Collateral.  If the  Collateral  contains
other goods not covered by this Agreement at the time of  repossession,  Grantor
agrees Lender may take such other goods,  provided that Lender makes  reasonable
efforts  to return  them to Grantor  after  repossession.  Sell the  Collateral.
Lender shall have full power to sell,  lease,  transfer,  or otherwise deal with
the  Collateral or proceeds  thereof In Its own name or that of Grantor.  Lender
may sell the Collateral at public auction or private sale. Unless the Collateral
threatens  to decline  speedily In value or Is of a type  customarily  sold on a
recognized market,  Lender will give Grantor reasonable notice of the time after
which any private sale or any other Intended disposition of the Collateral Is to
be made. The  requirements  of reasonable  notice shall be met If such notice Is
given at least ten (10) days,  or such  lesser  time as  required  by state law,
before  the  time of the  sale or  disposition.  All  expenses  relating  to the
disposition  of the  Collateral,  Including  without  limitation the expenses of
retaking,  holding,  Insuring,  preparing  for sale and selling the  Collateral,
shall become a part of the  Indebtedness  secured by this Agreement and shall be
payable on demand, with Interest at the Note rate from date of expenditure until
repaid.  Appoint  Receiver.  To the extent  permitted by applicable  law, Lender
shall have the  following  rights and remedies  regarding the  appointment  of a
receiver: (a) Lender may have a receiver appointed as a matter of right, (b) the
receiver may be an employee of Lender and may serve  without  bond,  and (c) all
fees  of  the  receiver  and  his or  her  attorney  shall  become  part  of the
Indebtedness  secured by this  Agreement  and shall be  payable on demand,  with
Interest at the Note rate from date of expenditure until repaid.

Collect Revenues,  Apply Accounts.  Lender, either Itself or through a receiver,
may collect the  payments,  rents,  Income,  and revenues  from the  Collateral.
Lender may at any time in Its discretion  transfer any  Collateral  Into Its own
name or that of Its  nominee  and  receive  the  payments,  rents,  Income,  and
revenues  therefrom and hold the same as security for the  Indebtedness or apply
it to payment of the  Indebtedness  in such  order of  preference  as Lender may
determine.  Insofar as the Collateral consists of accounts, general Intangibles,
Insurance  policies,  instruments,  chattel paper,  choses In action, or similar
property, Lender may demand, collect, receipt for, settle,  compromise,  adjust,
sue for,  foreclose,  or realize  on the  Collateral  as Lender  may  determine,
whether or not  Indebtedness  or  Collateral  Is then due.  For these  purposes,
Lender may, on behalf of and in the name of Grantor,  receive,  open and dispose
of mail addressed to Grantor;  change any address to which mail and payments are
to be sent; and endorse notes, checks, drafts, money orders, documents of title,
Instruments  and Items  pertaining  to  payment,  shipment,  or  storage  of any
Collateral.  To facilitate  collection,  Lender may notify  account  debtors and
obligors  on  any  Collateral  to  make  payments  directly  to  Lender.  Obtain
Deficiency.  If Lender chooses to sell any or all of the Collateral,  Lender may
obtain  a  judgment  against  Borrower  for  any  deficiency  remaining  on  the
Indebtedness  due to Lender after  application of all amounts  received from the
exercise of the rights provided In this Agreement.  Borrower shall be liable for
a deficiency even If the  transaction  described In this subsection Is a sale of
accounts or chattel paper.

Other  Rights and  Remedies.  Lender shall have all the rights and remedies of a
secured creditor under the provisions of the Uniform  Commercial Code, as may be
amended from time to time.  In addition,  Lender shall have and may exercise any
or all other  rights and remedies It may have  available  at law, In equity,  or
otherwise.

Cumulative Remedies.  All of Lender's rights and remedies,  whether evidenced by
this  Agreement  or the  Related  Documents  or by any other  writing,  shall be
cumulative and may be exercised  singularly or concurrently.  Election by Lender
to pursue any remedy  shall not  exclude  pursuit  of any other  remedy,  and an
election  to make  expenditures  or to take action to perform an  obligation  of
Grantor or Borrower under this Agreement, after Grantor or Borrower's failure to
perform,  shall not affect  Lender's  right to declare a default and to exercise
Its remedies.

Borrower or any other guarantor,  surety, or other person, and further,  Grantor

hereafter held by Lender.

Indebtedness  shall not at all times until paid be fully  secured by  collateral
pledged by Borrower,  Grantor hereby forever waives and relinquishes In favor of
Lender and  Borrower,  and their  respective  successors,  any claim or right to

subrogation  or  otherwise,  so that at no time  shall  Grantor  be or  become a
"creditor" of Borrower within the meaning of 11 U.S.C.  section  547(b),  or any
successor provision of the Federal bankruptcy laws.

RIGHT OF SETOFF. Grantor hereby grants Lender a contractual security Interest In
and hereby assigns, conveys,  delivers,  pledges, and transfers all of Grantor's
right,  title and Interest In and to  Grantor's  accounts  with Lender  (whether

with someone else and all  accounts  Grantor may open In the future,  excluding,
however, all IRA and Keogh accounts,  and all trust accounts for which the grant
of a security Interest would be prohibited by law. Grantor authorizes Lender, to
the extent  permitted by  applicable  law, to charge or setoff all  Indebtedness
against any and all such accounts.

OBLIGATIONS OF GRANTOR. Grantor warrants and covenants to Lender as follows:
Perfection  of  Security  Interest.  Grantor  agrees to execute  such  financing
statements and to take whatever other actions are requested by Lender to perfect

Grantor  hereby  appoints  Lender as Its  Irrevocable  attorney-in-fact  for the
purpose of  executing  any  documents  necessary  to perfect or to continue  the
security interest granted In this Agreement. Lender may at any time, and without

perfection and the continuation of the perfection of Lender's  security Interest
in the  Collateral.  Grantor  promptly  will notify  Lender before any change In
Grantor's  name  Including any change to the assumed  business names of Grantor.
This Is a continuing  Security Agreement and will continue In effect even though
all or any part of the Indebtedness Is paid In full and even though for a period
of time Borrower may not be Indebted to Lender.

No Violation.  The execution and delivery of this Agreement will not violate any
law or  agreement  governing  Grantor or to which  Grantor  is a party,  and Its
articles  or  agreements  relating  to  entity  Incorporation,  organization  or
existence do not prohibit any term or condition of this Agreement.

chattel  paper,  or  general  Intangibles,  the  Collateral  Is  enforceable  in
accordance  with Its terms,  Is  genuine,  and  compiles  with  applicable  laws

persons  appearing to be obligated on the Collateral have authority and capacity

locations as are  acceptable  to Lender.  Except in the  ordinary  course of Its
business,  Including  the  sales of  Inventory,  Grantor  shall not  remove  the
Collateral  from Its existing  locations  without the prior  written  consent of
Lender. To the extent that the Collateral consists of vehicles,  or other titled

Transactions  Involving  Collateral.  Except  for  Inventory  sold  or  accounts
collected In the ordinary course of Grantor's business,  Grantor shall not sell,

the ordinary course of Its business and only to buyers who quality as a buyer In
the  ordinary  course of business.  A sale In the  ordinary  course of Grantor's
business does not Include a transfer In partial or total  satisfaction of a debt

and liens upon the Collateral,  its use or operation,  upon this Agreement, upon
any promissory  note or notes  evidencing the  indebtedness,  or upon any of the
other Related  Documents.  Grantor may withhold any such payment or may elect to
contest  any  lien  if  Grantor  is in  good  faith  conducting  an  appropriate
proceeding to contest the obligation to pay and so long as Lender's  interest in
the Collateral is not jeopardized in Lender's sole opinion. If the collateral is
subjected to a lien which is not discharged  within  fifteen (15) days,  Grantor
shall  deposit with Lender cash,  a  sufficient  corporate  surety bond or other
security  satisfactory  to Lender  in an  amount  adequate  to  provide  for the
discharge of the lien plus any interest, costs, attorneys' fees or other charges
that could accrue as a result of foreclosure or sale of the  Collateral.  In any
contest  Grantor  shall  defend  itself and Lender and shall  satisfy  any final
adverse judgment before enforcement  against the Collateral.  Grantor shall name
Lender as an additional  obligee under any surety bond  furnished in the contest

or  regulation  and  withhold   compliance  during  any  proceeding,   including
appropriate appeals, so long as Lender's interest in the Collateral, in Lender's
opinion, is not jeopardized.

Hazardous Substances.  Grantor represents and warrants that the Collateral never
has been,  and  never  will be so long as this  Agreement  remains a lien on the
Collateral,  used  for the  generation,  manufacture,  storage,  transportation,
treatment,  disposal,  release or threatened  released of any hazardous waste or
substance,  as  those  terms  are  defined  in the  Comprehensive  Environmental
Response, Compensation, and Liability Act of 1980, as amended, 42 U.S.C. Section
9601, et seq.  ("CERCLA"),  the Superfund  Amendments and Reauthorization Act of
1986,  Pub.L.No.99-499  ("SARA"), the Hazardous Materials Transportation Act, 49
U.S.C.  Section 1801, et seq.,  the Resource  Conservation  and Recovery Act, 42
U.S.C.  Section  6901,  et seq.  Chapters  6.5  through  7.7 of  Division of the
California  Health and safety Code,  Section 25100, et seq., or other applicable
state or Federal laws,  rules,  or  regulations  adopted  pursuant to any of the
foregoing.  The terms  "hazardous  waste" and "hazardous  substance"  shall also
Include, without limitation, petroleum and petroleum by-products or any fraction
thereof and asbestos.  The representations  and warranties  contained herein are
based on Grantor's due diligence In  Investigating  the Collateral for hazardous
wastes and substances.  Grantor hereby (a) releases and waives any future claims
against Lender for Indemnity or contribution In the event Grantor becomes liable
for cleanup or other costs under any such laws,  and (b) agrees to Indemnity and
hold  harmless  Lender  against any and all claims and losses  resulting  from a
breach of this provision of this  Agreement.  This obligation to Indemnity shall
survive the payment of the Indebtedness and the satisfaction of this Agreement.

Maintenance of Casualty Insurance.  Grantor shall procure and maintain all risks
Insurance,  Including  without  limitation  fire,  theft and liability  coverage
together  with such other  Insurance  as Lender may require  with respect to the
Collateral,  In form,  amounts,  coverages  and basis  reasonably  acceptable to
Lender and Issued by a company or  companies  reasonably  acceptable  to Lender.
Grantor,  upon  request of Lender,  will deliver to Lender from time to time the
policies or certificates of Insurance In form satisfactory to Lender,  Including
stipulations that coverages will not be cancelled or diminished without at least
ton (10) days' prior written  notice to Lender and not Including any  disclaimer
of the  Insurer's  liability for failure to give such a notice.  Each  Insurance
policy also shall  Include an  endorsement  providing  that coverage In favor of
Lender  will not be  Impaired  In any way by any act,  omission  or  default  of
Grantor or any other person.  In connection with all policies covering assets In
which  Lender  holds or Is offered a security  Interest,  Grantor  will  provide
Lender with such loss payable or other  endorsements  as Lender may require.  If
Grantor at any time falls to obtain or maintain any Insurance as required  under
this Agreement, Lender may (but shall not be obligated to) obtain such Insurance
as  Lender  deems  appropriate,  Including  If It so  chooses  "single  Interest
Insurance," which will cover only Lender's Interest In the Collateral.

Application of Insurance  Proceeds.  Grantor shall promptly notify Lender of any
material  loss or damage to the  Collateral.  Lender  may make  proof of loss If
Grantor falls to do so within fifteen (15) days of the casualty. All proceeds of
any Insurance on the Collateral,  including accrued proceeds  thereon,  shall be
held by  Lender  as part of the  Collateral.  If  Lender  consents  to repair or
replacement  of  the  damaged  or  destroyed  Collateral,   Lender  shall,  upon
satisfactory  proof of expenditure,  pay or reimburse  Grantor from the proceeds
for the reasonable cost of repair or restoration.  If Lender does not consent to
repair or replacement of the Collateral, Lender shall retain a sufficient amount
of the  proceeds  to pay all of the  Indebtedness,  and shall pay the balance to
Grantor.  Any proceeds which have not been disbursed  within six(6) months after
their receipt and which  Grantor has not committed to the repair or  restoration
of the Collateral shall be used to prepay the Indebtedness on a material portion
of the collateral.

Insurance  Reserves  following an event of default Lender may require Grantor to
maintain with Lender reserves for payment of Insurance premiums,  which reserves
shall be created by monthly  payments  from Grantor of a sum estimated by Lender
to be sufficient  to produce,  at least fifteen (15) days before the premium due
date,  amounts at least equal to the  Insurance  premiums to be paid. If fifteen
(15) days before  payment Is due, the reserve  funds are  Insufficient,  Grantor
shall upon demand pay any deficiency to Lender.  The reserve funds shall be held
by Lender as a general  deposit  and  shall  constitute  a  non-interest-bearing
account which Lender may satisfy by payment of the Insurance  premiums  required
to be paid by Grantor as they become due. Lender does not hold the reserve funds
In trust for Grantor,  and Lender is not the agent of Grantor for payment of the
Insurance  premiums required to be paid by Grantor.  The  responsibility for the
payment of  premiums  shall  remain  Grantor's  sole  responsibility.  Insurance
Reports.  Grantor,  upon request of Lender,  shall furnish to Lender  reports on
each  existing  policy of  Insurance  showing  such  Information  as Lender  may
reasonably request Including the following: (a) the name of the Insurer; (b) the
risks Insured;  (c) the amount of the policy; (d) the property Insured;  (e) the
then current  value on the basis of which  Insurance  has been  obtained and the
manner of determining that value; and (f) the expiration date of the policy.  In
addition,  Grantor  shall upon  request by Lender  (however  not more often than
annually)have  an Independent  appraiser  satisfactory to Lender  determine,  as
applicable, the cash value or replacement cost of the Collateral.

GRANTOR'S RIGHT TO POSSESSION. Until default, Grantor may have possession of the
tangible  personal property and beneficial use of all the Collateral and may use
it in any lawful  manner not  Inconsistent  with this  Agreement  or the Related
Documents,  provided that Grantor's right to possession and beneficial use shall
not apply to any  Collateral  where  possession  of the  Collateral by Lender Is
required by law to perfect Lender's  security  Interest In such  Collateral.  It
Lender at any time has possession of any Collateral,  whether before or after an
Event of Default,  Lender shall be deemed to have exercised  reasonable  care In
the custody and  preservation  of the Collateral If Lender takes such action for
that purpose as Grantor shall request or as Lender, In Lender's sole discretion,
shall deem appropriate under the circumstances, but failure to honor any request
by Grantor shall not of itself be deemed to be a failure to exercise  reasonable
care.  Lender shall not be required to take any steps  necessary to preserve any
rights In the  Collateral  against prior  parties,  nor to protect,  preserve or
maintain any security Interest given to secure the Indebtedness.

EXPENDITURES  BY LENDER.  If not  discharged  or paid when due,  Lender may (but
shall  not  be  obligated  to)  discharge  or pay  any  amounts  required  to be
discharged or paid by Grantor under this Agreement, Including without limitation
all taxes,  liens,  security Interests,  encumbrances,  and other claims, at any
time  levied or  placed on the  Collateral.  Lender  also may (but  shall not be
obligated  to) pay all  costs  for  Insuring,  maintaining  and  preserving  the
Collateral.  All such expenditures  Incurred or paid by Lender for such purposes
will  then  bear  Interest  at the rate  charged  under  the Note  from the date
Incurred  or paid by  Lender  to the  date of  repayment  by  Grantor.  All such
expenses shall become a part of the Indebtedness  and, at Lender's option,  will
(a) be  payable  on  demand,  (b) be  added  to the  balance  of the Note and be
apportioned  among and be payable  with any  installment  payments to become due
during  either  (i) the  term of any  applicable  Insurance  policy  or (ii) the
remaining term of the Note, or (c) be treated as a balloon payment which will be
due and payable at the Note's maturity.  This Agreement also will secure payment
of these  amounts.  Such  right  shall be In  addition  to all other  rights and
remedies to which  Lender may be  entitled  upon the  occurrence  of an Event of
Default.

repay the Loans or perform their respective obligations, under this Agreement or
any of the Related Documents.

the Related Documents Is false or misleading in any material respect, either now
or at the time made or furnished.

faith dispute by Grantor or Borrower as to the validity or reasonableness of the
claim which Is the basis of the creditor or forfeiture proceeding and If Grantor
or Borrower gives Lender written notice of the creditor or forfeiture proceeding
and deposits  with Lender monies or a surety bond for the creditor or forfeiture

the  guaranty  in a manner  satisfactory  to Lender,  and, in doing so, cure the
Event of Default.

Adverse  Change.  A  Material  adverse  change  occurs in  Borrower's  financial
condition,  or Lender reasonable believes the prospect of payment or performance
of the indebtedness is impaired.

Right to Cure. If any default, other than a Default on indebtedness,  is curable
and if Grantor or Borrower  has not been given a prior notice of a breach of the
same provision of the  Agreement,  it may be cured (and no Event of Default will
have  occurred)  if Grantor or  `Borrower,  after Lender  sends  written  notice
demanding  cure of such default,  (a) cures the default within ten (10) days; or
(b) if the cure requires more than ten (10) days,  immediately  initiates  steps
which Lender deems in Lender's  sole  discretion  to be  sufficient  to cure the
default and  thereafter  continues and completes  all  reasonable  and necessary
steps sufficient to produce compliance as soon as reasonably practical.

RIGHTS  AND  REMEDIES  ON  DEFULT.  If an Event of  Default  occurs  under  this
Agreement, at any time thereafter, Lender shall have all the rights of a secured
party under the  California  Uniform  Commercial  Code.  In addition and without
limitation,  Lender may  exercise  any one or more of the  following  rights and
remedies:

Accelerate Indebtedness.  Lender may declare the entire Indebtedness,  including
any prepayment penalty which Borrower would be required to pay,  immediately due
and payable, without notice.

Assemble Collateral.  Lender may require Grantor to deliver to Lender all or any
portion  of the  Collateral  and any and all  certificates  of title  and  other
documents relating to the Collateral. Lender may require Grantor to assemble the
Collateral  and make It  available  to  Lender  at a place to be  designated  by
Lender.  Lender also shall have full power to enter upon the property of Grantor
to take  possession of and remove the  Collateral.  If the  Collateral  contains
other goods not covered by this Agreement at the time of  repossession,  Grantor
agrees Lender may take such other goods,  provided that Lender makes  reasonable
efforts  to return  them to Grantor  after  repossession.  Sell the  Collateral.
Lender shall have full power to sell,  lease,  transfer,  or otherwise deal with
the  Collateral or proceeds  thereof In Its own name or that of Grantor.  Lender
may sell the Collateral at public auction or private sale. Unless the Collateral
threatens  to decline  speedily In value or Is of a type  customarily  sold on a
recognized market,  Lender will give Grantor reasonable notice of the time after
which any private sale or any other Intended disposition of the Collateral Is to
be made. The  requirements  of reasonable  notice shall be met If such notice Is
given at least ten (10) days,  or such  lesser  time as  required  by state law,
before  the  time of the  sale or  disposition.  All  expenses  relating  to the
disposition  of the  Collateral,  Including  without  limitation the expenses of
retaking,  holding,  Insuring,  preparing  for sale and selling the  Collateral,
shall become a part of the  Indebtedness  secured by this Agreement and shall be
payable on demand, with interest at the Note rate from date of expenditure until
repaid.

Appoint  Receiver.  To the extent permitted by applicable law, Lender shall have
the following rights and remedies  regarding the appointment of a receiver:  (a)
Lender may have a receiver  appointed as a matter of right, (b) the receiver may
be an employee  of Lender and may serve  without  bond,  and (c) all fees of the
receiver and his or her attorney shall become part of the  Indebtedness  secured
by this Agreement and shall be payable on demand, with Interest at the Note rate
from date of expenditure until repaid.

Collect Revenues,  Apply Accounts.  Lender, either itself or through a receiver,
may collect the  payments,  rents,  Income,  and revenues  from the  Collateral.
Lender may at any time In its discretion  transfer any  Collateral  into Its own
name or that of Its  nominee  and  receive  the  payments,  rents,  Income,  and
revenues  therefrom and hold the same as security for the  Indebtedness or apply
It to payment of the  Indebtedness  in such  order of  preference  as Lender may
determine.  Insofar as the Collateral consists of accounts, general Intangibles,
Insurance  policies,  Instruments,  chattel paper,  choses in action, or similar
property, Lender may demand, collect, receipt for, settle,  compromise,  adjust,
sue for,  foreclose,  or realize  on the  Collateral  as Lender  may  determine,
whether or not  Indebtedness  or  Collateral  Is then due.  For these  purposes,
Lender may, on behalf of and In the name of Grantor,  receive,  open and dispose
of mail addressed to Grantor;  change any address to which mail and payments are
to be sent; and endorse notes, checks, drafts, money orders, documents of title,
Instruments  and Items  pertaining  to  payment,  shipment,  or  storage  of any
Collateral.  To facilitate  collection,  Lender may notify  account  debtors and
obligors  on  any  Collateral  to  make  payments  directly  to  Lender.  Obtain
Deficiency.  If Lender chooses to sell any or all of the Collateral,  Lender may
obtain  a  judgment  against  Borrower  for  any  deficiency  remaining  on  the
Indebtedness  due to Lender after  application of all amounts  received from the
exercise of the rights provided in this Agreement.  Borrower shall be liable for
a deficiency even If the  transaction  described In this subsection Is a sale of
accounts or chattel paper.

Other  Rights and  Remedies.  Lender shall have all the rights and remedies of a
secured creditor under the provisions of the Uniform  Commercial Code, as may be
amended from time to time.  In addition,  Lender shall have and may exercise any
or all other  rights and remedies It may have  available  at law, In equity,  or
otherwise.

Cumulative Remedies.  All of Lender's rights and remedies,  whether evidenced by
this  Agreement  or the  Related  Documents  or by any other  writing,  shall be
cumulative and may be exercised  singularly or concurrently.  Election by Lender
to pursue any remedy  shall not  exclude  pursuit  of any other  remedy,  and an
election  to make  expenditures  or to take action to perform an  obligation  of
Grantor or Borrower under this Agreement, after Grantor or Borrower's failure to
perform,  shall not affect  Lender's  right to declare a default and to exercise
its remedies.

or omission  on the part of Lender in  exercising  any right shall  operate as a
waiver of such right or any other  right.  A waiver by Lender of a provision  of
this  Agreement  shall not  prejudice or  constitute a waiver of Lender's  right
otherwise to demand strict compliance with that provision or any other provision
of this Agreement.  No prior waiver by Lender, nor any course of dealing between
Lender and Grantor,  shall  constitute a waiver of any Lender's rights or of any
of Grantor's obligations as to any future transactions.  Whenever the consent of
Lender is required under this Agreement,  the granting of such consent by Lender
in any instance shall not constitute  continuing consent to subsequent instances
where such  consent is required  and in all cases such consent may be granted or
withheld in the sole discretion of Lender.

Waiver of  Co-obligor's  Rights.  If more than one person is  obligated  for the
indebtedness, Borrower irrevocably waives, disclaims and relinquishes all claims
against such other person which  Borrower has or would  otherwise have by virtue
of payment of the indebtedness or any part thereof,  specifically  including but

Grantor waives all rights and defenses arising out of an election of remedies by

with respect to security for a guaranteed  obligation,  has destroyed  Grantor's
rights of subrogation  and  reimbursement  against  Borrower by the operation of
Section 580d of the  California  Code of Civil  Procedure,  or  otherwise.  This
waiver Includes,  without  limitation,  any loss of rights Grantor may suffer by

security for the  Indebtedness  Including,  but not limited to, the right to any
fair market value hearing pursuant to California Code of Civil Procedure Section
580a.

Grantor  understands  and  agrees  that the  foregoing  waivers  are  waivers of
substantive  rights and defenses to which  Grantor  might  otherwise be entitled
under state and federal  law. The rights and defenses  waived  Include,  without
limitation,  those  provided by  California  laws of  suretyship  and  guaranty,
anti-deficiency laws, and the Uniform Commercial Code. Grantor acknowledges that
Grantor has provided  these  waivers of rights and defenses  with the  intention
that they be fully  relied  upon by Lender.  Until all  Indebtedness  Is paid In
full,  Grantor  waives any right to enforce any remedy  Lender may have  against
Borrower or any other guarantor,  surety, or other person, and further,  Grantor
waives any right to participate in any  collateral for the  Indebtedness  now or
hereafter held by Lender.

If now or  hereafter  (a)  Borrower  shall be or become  Insolvent,  and (b) the
Indebtedness  shall not at all times until paid be fully  secured by  collateral
pledged by Borrower,  Grantor hereby forever waives and relinquishes In favor of
Lender and  Borrower,  and their  respective  successors,  any claim or right to
payment Grantor may now have or hereafter have or acquire against  Borrower,  by
subrogation  or  otherwise,  so that at no time  shall  Grantor  be or  become a
"creditor"  of Borrower  within the meaning of 11 U.S.C.  section  547(b),or any
successor provision of the Federal bankruptcy laws.

RIGHT OF SETOFF. Grantor hereby grants Lender a contractual security Interest In
and hereby assigns, conveys,  delivers,  pledges, and transfers all of Grantor's
right,  title and Interest In and to  Grantor's  accounts  with Lender  (whether
checking,  savings, or some other account),  Including all accounts held jointly
with someone else and all  accounts  Grantor may open In the future,  excluding,
however, all IRA and Keogh accounts,  and all trust accounts for which the grant
of a security Interest would be prohibited by law. Grantor authorizes Lender, to
the extent  permitted by  applicable  law, to charge or setoff all  Indebtedness
against any and all such accounts.

OBLIGATIONS OF GRANTOR. Grantor Warrants and covenants to Lender as follows:
Perfection  of  Security  Interest.  Grantor  agrees to execute  such  financing
statements and to take whatever other actions are requested by Lender to perfect
and  continue  Lender's  security  Interest In the  Collateral.  Upon request of
Lender,  Grantor will deliver to Lender any and all of the documents  evidencing
or constituting the Collateral, and Grantor will note Lender's Interest upon any
and all  chattel  paper If not  delivered  to Lender for  possession  by Lender.
Grantor  hereby  appoints  Lender as Its  Irrevocable  attorney-in-fact  for the
purpose of  executing  any  documents  necessary  to perfect or to continue  the
security Interest granted In this Agreement. Lender may at any time, and without
further  authorization  from  Grantor,  file a  carbon,  photographic  or  other
reproduction  of any  financing  statement  or of  this  Agreement  for use as a
financing  statement.  Grantor  will  reimburse  Lender for all expenses for the
perfection and the continuation of the perfection of Lender's  security interest
in the  Collateral.  Grantor  promptly  will notify  Lender before any change In
Grantor's  name  Including any change to the assumed  business names of Grantor.
This Is a continuing  Security Agreement and will continue In effect even though
all or any part of the  Indebtedness  Is paid.  In full  and even  though  for a
period of time Borrower may not be Indebted to Lender.

No Violation.  The execution and delivery of this Agreement will not violate any
law or  agreement  governing  Grantor or to which  Grantor  Is a party,  and its
articles  or  agreements  relating  to  entity  incorporation,  organization  or
existence do not prohibit any term or condition of this Agreement.

Enforceability of Collateral. To the extent the Collateral consists of accounts,
chattel  paper,  or  general  Intangibles,  the  Collateral  Is  enforceable  In
accordance  with its terms,  is  genuine,  and  compiles  with  applicable  laws
concerning  form,  content  and manner of  preparation  and  execution,  and all
persons  appearing to be obligated on the Collateral have authority and capacity
to contract and are In fact obligated as they appear to be on the Collateral.

Location of the  Collateral.  Grantor,  upon request of Lender,  will deliver to
Lender  In form  satisfactory  to  Lender  a  schedule  of real  properties  and
Collateral  locations  relating  to  Grantor's  operations,   Including  without
limitation  the  following:  (a) all real property  owned or being  purchased by
Grantor;  (b) all real  property  being  rented or leased  by  Grantor;  (c) all
storage facilities owned, rented,  leased, or being used by Grantor; and (d) all
other properties  where Collateral Is or may be located.  Except In the ordinary

existing locations without the prior written consent of Lender.

Removal of  Collateral.  Grantor shall keep the Collateral (or to the extent the
Collateral  consists  of  Intangible  property  such as  accounts,  the  records
concerning the  Collateral) at Grantor's  address shown above,  or at such other
locations as are  acceptable  to Lender.  Except in the  ordinary  course of Its
business,  Including  the  sales of  Inventory,  Grantor  shall not  remove  the
Collateral  from Its existing  locations  without the prior  written  consent of
Lender. To the extent that the Collateral consists of vehicles,  or other titled
property,  Grantor  shall not take or permit  any  actr6n  which  would  require
application  for  certificates  of title for the  vehicles  outside the State of
California,  without the prior written consent of Lender. Transactions Involving
Collateral.  Except for  inventory  sold or accounts  collected  In the ordinary
course  of  Grantor's  business,  Grantor  shall  not  sell,  offer to sell,  or
otherwise transfer or dispose of the Collateral. While Grantor Is not In default
under this  Agreement,  Grantor  may sell  Inventory,  but only In the  ordinary
course of Its business and only to buyers who quality as a buyer in the ordinary
course of business. A sale in the ordinary course of Grantor's business does not
Include a transfer in partial or total  satisfaction of a debt or any bulk sale.
Grantor shall not pledge, mortgage,  encumber or otherwise permit the Collateral
to be subject to any lien, security Interest, encumbrance, or charge, other than
the security Interest provided for In this Agreement,  without the prior written
consent of Lender.  This Includes security  Interests even If junior In right to
the security  Interests  granted under this Agreement.  Unless waived by Lender,
all proceeds from any disposition of the Collateral (for whatever  reason) shall
be held in trust for Lender and shall not be  commingled  with any other  funds;
provided however, this requirement shall not constitute consent by Lender to any
sale or other disposition.  Upon receipt,  Grantor shall Immediately deliver any
such proceeds to Lender.  Title.  Grantor represents and warrants to Lender that
It holds  good and  marketable  title to the  Collateral,  free and clear of all
liens and  encumbrances  except  for the lien of this  Agreement.  No  financing
statement  covering any of the  Collateral is on file in any public office other
than those which reflect the security  interest  created by this Agreement or to
which Lender has specifically consented. Grantor shall defend Lender's rights In
the Collateral against the claims and demands of all other persons.

Collateral  Schedules  and  Locations.  Insofar as the  Collateral  consists  of
Inventory,,  Grantor shall deliver to Lender,  as often as Lender shall require,
such lists,  descriptions,  and  designations  of such  Collateral as Lender may
require to Identify the nature,  extent,  and location of such Collateral.  Such
Information  shall be  submitted  for  Grantor and each of Its  subsidiaries  or
related companies.

Maintenance  and Inspection of  Collateral.  Grantor shall maintain all tangible
Collateral  In good  condition  and  repair.  Grantor  will not commit or permit
damage to or destruction of the Collateral or any part of the Collateral. Lender
and Its  designated  representatives  and  agents  shall  have the  right at all
reasonable times to examine, inspect, and audit the Collateral wherever located.
Grantor  shall  Immediately  notify  Lender of all cases  Involving  the return,
rejection,  repossession, loss or damage of or to any Collateral; of any request
for credit or  adjustment  or of any other  dispute  arising with respect to the
Collateral;  and generally of all happenings and events affecting the Collateral
or the value or the amount of the Collateral.

Taxes, Assessments and Liens. Grantor will pay when due all taxes, assessments
Compliance  With  Government  Requirements.  Grantor shall comply with all laws,
ordinances,  rules  and  regulations  of all  governmental  authorities,  now or
hereafter in effect, applicable to the ownership,  production,  disposition,  or
use of the Collateral. Grantor may contest in good faith any such law, ordinance
or  regulation  and  withhold   compliance  during  any  proceeding,   including
appropriate appeals, so long as Lender's interest in the Collateral, in Lender's
opinion, is not jeopardized.

Hazardous Substances.  Grantor represents and warrants that the Collateral never
has been,  and  never  will be so long as this  Agreement  remains a lien on the
Collateral,  used  for the  generation,  manufacture,  storage,  transportation,
treatment,  disposal,  release or threatened  released of any hazardous waste or
substance,  as  those  terms  are  defined  in the  Comprehensive  Environmental
Response, Compensation, and Liability Act of 1980, as amended, 42 U.S.C. Section
9601, et seq.  ("CERCLA"),  the Superfund  Amendments and Reauthorization Act of
1986,  Pub.L.No.99-499  ("SARA"), the Hazardous Materials Transportation Act, 49
U.S.C.  Section 1801, et seq.,  the Resource  Conservation  and Recovery Act, 42
U.S.C.  Section  6901,  et seq.,  Chapters 6.5 through 7.7 of Division 20 of the
California  Health and Safety Code,  Section 25100, et seq., or other applicable
state or Federal laws,  rules,  or  regulations  adopted  pursuant to any of the
foregoing.  The terms  "hazardous  waste" and "hazardous  substance"  shall also
include, without limitation,  petroleum and petroleum byproducts or any traction
thereof and asbestos.  The representations  and warranties  contained herein are
based on Grantor's due diligence In  Investigating  the Collateral for hazardous
wastes and substances.  Grantor hereby (a) releases and waives any future claims
against Lender for Indemnity or contribution In the event Grantor becomes liable
for cleanup or other costs under any such laws,  and (b) agrees to Indemnify and
hold  harmless  Lender  against any and all claims and losses  resulting  from a
breach of this provision of this  Agreement.  This obligation to Indemnity shall
survive the payment of the Indebtedness and the satisfaction of this Agreement.

Maintenance of Casualty Insurance.  Grantor shall procure and maintain all risks
insurance,  including  without  limitation  fire,  theft and liability  coverage
together  with such other  Insurance  as Lender may require  with respect to the
Collateral,  in form,  amounts,  coverages  and basis  reasonably  acceptable to
Lender and Issued by a company or  companies  reasonably  acceptable  to Lender.
Grantor,  upon  request of Lender,  will deliver to Lender from time to time the
policies or certificates of Insurance In form satisfactory to Lender,  including
stipulations that coverages will not be cancelled or diminished without at least
ten (10) days' prior written  notice to Lender and not including any  disclaimer
of the  Insurer's  liability for failure to give such a notice.  Each  Insurance
policy also shall  Include an  endorsement  providing  that coverage In favor of
Lender will not be Impaired in any way by any act, omission or default of

Grantor or any other person. In connection with all policies covering assets In
which  Lender  holds or is offered a security  Interest,  Grantor  will  provide
Lender with such loss payable or other  endorsements  as Lender may require.  If
Grantor at any time falls to obtain or maintain any Insurance as required  under
this Agreement, Lender may (but shall not be obligated to) obtain such Insurance
as  Lender  deems  appropriate,  Including  If It so  chooses  "single  Interest
insurance," which will cover only Lender's Interest In the Collateral.

Application of Insurance  Proceeds.  Grantor shall promptly notify Lender of any
loss  material  or damage to the  Collateral.  Lender  may make proof of loss If
Grantor falls to do so within fifteen (15) days of the casualty. All proceeds of
any Insurance on the Collateral,  Including accrued proceeds  thereon,  shall be
held by  Lender  as part of the  Collateral.  If  Lender  consents  to repair or
replacement  of  the  damaged  or  destroyed  Collateral,   Lender  shall,  upon
satisfactory  proof of expenditure,  pay or reimburse  Grantor from the proceeds
for the reasonable cost of repair or restoration.  If Lender does not consent to
repair or replacement of the Collateral, Lender shall retain a sufficient amount
of the  proceeds  to pay all of the  Indebtedness,  and shall pay the balance to
Grantor.  Any proceeds which have not been disbursed within six (6) months after
their receipt and which  Grantor has not committed to the repair or  restoration
of the Collateral shall be used to prepay the Indebtedness.  Insurance  Reserve.
Lender may require  Grantor to  maintain  with  Lender  reserves  for payment of
Insurance  premiums,  which reserves  shall be created by monthly  payments from
Grantor of a sum  estimated  by Lender to be  sufficient  to  produce,  at least
fifteen  (15) days before the  premium  due date,  amounts at least equal to the
Insurance  premiums to be paid. If fifteen (15) days before  payment Is due, the
reserve funds are Insufficient,  Grantor shall upon demand pay any deficiency to
Lender. The reserve funds shall be held by Lender as a general deposit and shall
constitute a non-Interest-bearing account which Lender may satisfy by payment of
the Insurance premiums required to be paid by Grantor as they become due. Lender
does not hold the  reserve  funds In trust for  Grantor,  and  Lender Is not the
agent of Grantor for payment of the  insurance  premiums  required to be paid by
Grantor.  The  responsibility for the payment of premiums shall remain Grantor's
sole responsibility.

Insurance  Reports.  Grantor,  upon request of Lender,  shall  furnish to Lender
reports on each existing policy of Insurance  showing such Information as Lender
may reasonably request Including the following: (a) the name of the Insurer; (b)
the risks  Insured;  (c) the amount of the  policy;  (d) the  property  Insured;
(e)the then current value on the basis of which  Insurance has been obtained and
the manner of determining that value; and (f)the  expiration date of the policy.
In addition,  Grantor shall upon request by Lender  (however not more often than
annually)have  an Independent  appraiser  satisfactory to Lender  determine,  as
applicable, the cash value or replacement cost of the Collateral.

GRANTOR'S RIGHT TO POSSESSION. Until default, Grantor may have possession of the
tangible  personal property and beneficial use of all the Collateral and may use
it in any lawful  manner not  Inconsistent  with this  Agreement  or the Related
Documents,  provided that Grantor's right to possession and beneficial use shall
not apply to any  Collateral  where  possession  of the  Collateral by Lender is
required by law to perfect Lender's  security  Interest In such  Collateral.  If
Lender at any time has possession of any Collateral,  whether before or after an
Event of Default,  Lender shall be deemed to have exercised  reasonable  care In
the custody and  preservation  of the Collateral If Lender takes such action for
that purpose as Grantor shall request or as Lender, In Lender's sole discretion,
shall deem appropriate Under the circumstances, but failure to honor any request
by Grantor shall not of Itself be deemed to be a failure to exercise  reasonable
care.  Lender shall not be required to take any steps  necessary to preserve any
rights In the  Collateral  against prior  parties,  nor to protect,  preserve or
maintain any security Interest given to secure the Indebtedness.

EXPENDITURES  BY LENDER.  If not  discharged  or paid when due,  Lender may (but
shall  not  be  obligated  to)  discharge  or pay  any  amounts  required  to be
discharged or paid by Grantor under this Agreement, Including without limitation
all taxes,  liens,  security Interests,  encumbrances,  and other claims, at any
time  levied or  placed on the  Collateral.  Lender  also may (but  shall not be
obligated  to) pay all  costs  for  Insuring,  maintaining  and  preserving  the
Collateral.  All such expenditures  Incurred or paid by Lender for such purposes
will  then  bear  Interest  at the rate  charged  under  the Note  from the date
Incurred  or paid by  Lender  to the  date of  repayment  by  Grantor.  All such
expenses shall become a part of the Indebtedness  and, at Lender's option,  will
(a) be  payable  o6  demand,  (b) be added to the  balance  of the,  Note and be
apportioned  among and be payable  with any  installment  payments to become due
during  either  (i) the  term of any  applicable  Insurance  policy  or (ii) the
remaining term of the Note, or (c) be treated as a balloon payment which will be
due and payable at the Note's maturity.  This Agreement also will secure payment
of these  amounts.  Such  right  shall be in  addition  to all other  rights and
remedies  to which  Lender may b  entitled  upon the  occurrence  of an Event of
Default.

EVENTS OF DEFAULT.  Each of the following  shall  constitute an Event of Default
under this Agreement.  Default on Indebtedness.  Failure of Borrower to make any
payment  within  five days  following  the date due on the  Indebtedness.  Other
Defaults.  Failure of Grantor or Borrower to comply with or to perform any other
term, obligation, covenant or condition contained in this Agreement or In any of
the  Related  Documents  or failure of Borrower to comply with or to perform any
term, obligation, covenant or condition contained in any other agreement between
Lender and Borrower.

Default in Favor of Third Parties.  Should Borrower or any other Grantor default
under any loan,  extension  of credit,  security  agreement,  purchase  or sales
Agreement or any other for money  borrowed in excess of  $50,000.00  in favor of
any other creditor or person that may materially affect any Borrower's  Property
or  Borrowers  or any  Grantor's  ability  to repay the loans or  perform  their
respective obligations under this Agreement or any of the Related Documents.

False Statements. Any warranty, representation or statement made or furnished to
Lender by or on behalf of Grantor or Borrower under this Agreement,  the Note or
the Related Documents Is false or misleading In any material respect, either now
or at the time made or furnished.

Defective  Collateralization.  This  Agreement  or any of the Related  Documents
ceases to be In full  force and  effect  (including  failure  of any  collateral
documents to create a valid and perfected  security Interest or lien)at any time
and for any reason.  Insolvency  continued  in  paragraph  entitled  "Additional
Provision". The dissolution or termination of Grantor or Borrower's existence as
a going  business,  the Insolvency of Grantor or Borrower,  the appointment of a
receiver for any part of Grantor or Borrower's property,  any assignment for the
benefit of creditors,  any type of creditor workout,  or the commencement of any
proceeding  under any  bankruptcy  or Insolvency  laws by or against  Grantor or
Borrower.

Creditor or Forfeitures  Proceedings.  Commencement of foreclosure or forfeiture
proceedings,  whether by judicial  proceeding,  self-help,  repossession  or any
other  method,  by any  creditor of Grantor or  Borrower or by any  governmental
agency against the Collateral or any other collateral securing the Indebtedness.
This includes a garnishment  of any of Grantor or  Borrower's  deposit  accounts
with Lender.  However,  this Event of Default shall not apply If there Is a good
faith dispute by Grantor or Borrower as to the validity or reasonableness of the
claim which is the basis of the creditor or forfeiture proceeding and If Grantor
or Borrower gives Lender written notice of the creditor or forfeiture proceeding
and deposits  with Lender monies or a surety bond for the creditor or forfeiture
proceeding,  In an amount determined by Lender, in its sole discretion, as being
an adequate reserve or bond for the dispute.

Events Affecting  Guarantor.  Any of the preceding events occurs with respect to
any  `guarantor of any of the  indebtedness  or such  Guarantor  dies or becomes
incompetent.  Lender,  at its option,  may, but shall not be required to, permit
the Guarantor's estate to assume  unconditionally  the obligations arising under
the  guaranty  in a manner  satisfactory  to Lender,  and, in doing so, cure the
Event of Default.

Adverse  Change.  A  Material  adverse  change  occurs in  Borrower's  financial
condition,  or Lender reasonable believes the prospect of payment or performance
of the indebtedness is impaired.

Right to Cure. If any default, other than a Default on indebtedness,  is curable
and if Grantor or Borrower  has not been given a prior notice of a breach of the
same provision of the  Agreement,  it may be cured (and no Event of Default will
have  occurred)  if Grantor or  `Borrower,  after Lender  sends  written  notice
demanding  cure of such default,  (a) cures the default within ten (10) days; or
(b) if the cure requires more than ten (10) days,  immediately  initiates  steps
which Lender deems in Lender's  sole  discretion  to be  sufficient  to cure the
default and  thereafter  continues and completes  all  reasonable  and necessary
steps sufficient to produce compliance as soon as reasonably practical.

RIGHTS  AND  REMEDIES  ON  DEFULT.  If an Event of  Default  occurs  under  this
Agreement, at any time thereafter, Lender shall have all the rights of a secured
party under the  California  Uniform  Commercial  Code.  In addition and without
limitation,  Lender may  exercise  any one or more of the  following  rights and
remedies:

Accelerate Indebtedness.  Lender may declare the entire indebtedness,  including
any prepayment penalty which Borrower would be required to pay,  immediately due
and payable, without notice.

Assemble Collateral.  Lender may require Grantor to deliver to Lender all or any
portion  of the  Collateral  and any and all  certificates  of title  and  other
documents relating to the Collateral. Lender may require Grantor to assemble the
Collateral  and make It  available  to  Lender  at a place to be  designated  by
Lender.  Lender also shall have full power to enter upon the property of Grantor
to take  possession of and remove the  Collateral.  If the  Collateral  contains
other goods not covered by this Agreement at the time of  repossession,  Grantor
agrees Lender may take such other goods,  provided that Lender makes  reasonable
efforts to return them to Grantor after repossession.

Sell the Collateral.  Lender shall have full power to sell, lease,  transfer, or
otherwise deal with the  Collateral or proceeds  thereof In Its own name or that
of Grantor.  Lender may sell the  Collateral at public  auction or private sale.
Unless the  Collateral  threatens  to decline  speedily In value or is of a type
customarily  sold on a recognized  market,  Lender will give Grantor  reasonable
notice  of  the  time  after  which  any  private  sale  or any  other  Intended
disposition  of the  Collateral Is to be made.  The  requirements  of reasonable
notice  shall be met If such  notice  Is given at least ten (10)  days,  or such
lesser  time  as  required  by  state  law,  before  the  time  of the  sale  or
disposition.  All  expenses  relating  to the  disposition  of  the  Collateral,
Including  without  limitation  the  expenses of  retaking,  holding,  Insuring,
preparing  for sale  and  selling  the  Collateral,  shall  become a part of the
Indebtedness  secured by this  Agreement  and shall be  payable on demand,  with
Interest at the Note rate from date of expenditure until repaid.

the following rights and remedies  regarding the appointment of a receiver:  (a)
Lender may have a receiver  appointed as a matter of right, (b) the receiver may

by this Agreement and shall be payable on demand, with Interest at the Note rate
from date of expenditure until repaid.

Collect Revenues,  Apply Accounts.  Lender, either Itself or through a receiver,
may collect the  payments,  rents,  Income,  and revenues  from the  Collateral.
Lender may at any time In Its discretion  transfer any  Collateral  into Its own
name or that of Its  nominee  and  receive  the  payments,  rents,  Income,  and
revenues  therefrom and hold the same as security for the  Indebtedness or apply
it to payment of the  Indebtedness  In such  order of  preference  as Lender may
determine.  Insofar as the Collateral consists of accounts, general Intangibles,
Insurance  policies,  Instruments,  chattel paper,  choses In action, or similar
property, Lender may demand, collect, receipt for, settle,  compromise,  adjust,
sue for,  foreclose,  or realize  on the  Collateral  as Lender  may  determine,
whether or not  Indebtedness  or  Collateral  Is then due.  For these  purposes,
Lender may, on behalf of and In the name of Grantor,  receive,  open and dispose
of mail addressed to Grantor;  change any address to which mail and payments are
to be sent; and endorse notes, checks, drafts, money orders, documents of title,
Instruments and Items pertaining to payment, shipment, or storage of any

Collateral.  To facilitate  collection,  Lender may notify  account  debtors and
obligors  on  any  Collateral  to  make  payments  directly  to  Lender.  Obtain
Deficiency.  If Lender chooses to sell any or all of the Collateral,  Lender may
obtain  a  judgment  against  Borrower  for  any  deficiency  remaining  on  the
Indebtedness  due to Lender after  application of all amounts  received from the
exercise of the rights provided In this Agreement.  Borrower shall be liable for
a deficiency even If the  transaction  described In this subsection Is a sale of
accounts or chattel paper.

Other  Rights and  Remedies.  Lender shall have all the rights and remedies of a
secured creditor under the provisions of the Uniform  Commercial Code, as may be
amended from time to time.  In addition,  Lender shall have and may exercise any
or all other  rights and remedies It may have  available  at law, In equity,  or
otherwise.

Cumulative Remedies.  All of Lender's rights and remedies,  whether evidenced by
this  Agreement  or the  Related  Documents  or by any other  writing,  shall be
cumulative and may be exercised  singularly or concurrently.  Election by Lender
to pursue any remedy  shall not  exclude  pursuit  of any other  remedy,  and an
election  to make  expenditures  or to take action to perform an  obligation  of
Grantor or Borrower under this Agreement, after Grantor or Borrower's failure to
perform,  shall not affect  Lender's  right to declare a default and to exercise
Its remedies.

persons or  circumstances.  If feasible,  any such offending  provision shall be
deemed to be modified  to be within the limits of  enforceability  or  validity;
however, if the offending provision cannot be so modified,  it shall be stricken
and all other  provisions of this  Agreement in all other  respects shall remain
valid and enforceable.

Successor  Interests.  Subject to the limitations set forth above on transfer of
the  Collateral,  this Agreement shall be binding upon and inure to the benefits
of the parties, their successors and assigns.

Waiver.  Lender  shall  not be deemed  to have  waived  any  rights  under  this
Agreement unless such waiver is given in writing and signed by Lender.  No delay
or omission  on the part of Lender in  exercising  any right shall  operate as a
waiver of such right or any other  right.  A waiver by Lender of a provision  of
this  Agreement  shall not  prejudice or  constitute a waiver of Lender's  right
otherwise to demand strict compliance with that provision or any other provision
of this Agreement.  No prior waiver by Lender, nor any course of dealing between
Lender and Grantor,  shall  constitute a waiver of any Lender's rights or of any
of Grantor's obligations as to any future transactions.  Whenever the consent of
Lender is required under this Agreement,  the granting of such consent by Lender
in any instance shall not constitute  continuing consent to subsequent instances
where such  consent is required  and in all cases such consent may be granted or
withheld in the sole discretion of Lender.

Waiver of  Co-obligor's  Rights.  If more than one person is  obligated  for the
indebtedness, Borrower irrevocably waives, disclaims and relinquishes all claims
against such other person which  Borrower has or would  otherwise have by virtue
of payment of the indebtedness or any part thereof,  specifically  including but
not limited to all rights of indemnity, contribution or exoneration.
