ITEM 1.  DESCRIPTION OF BUSINESS

GENERAL

          IDSC was incorporated in the State of Nevada in June 1994. The
Company's Common Stock trades on the American Stock Exchange under the symbol
"IDS." Prior to June 16, 1998, the Company's Common Stock was traded on the
NASDAQ Electronic Bulletin Board under the symbol "IDDS."

         The Company has never filed for protection under the bankruptcy
protection act, nor has the Company or any of its assets been in receivership or
any other similar proceedings.

         The Company's revenue is derived from its five operating wholly owned
subsidiaries.

IDS

         IDS is a Texas corporation, which was formed in May 1985, and is a
wholly owned subsidiary of the Company. IDS was originally formed to provide
engineering consulting services to the pipeline divisions of major integrated
oil companies. The Company grew slowly to ten employees in 1989. At that time, a
strategic decision was made by management to enter the industrial computer
marketplace. In 1989, the Company designed and built its first industrial
computer and in 1991 hired its first marketing manager. The Company continued to
support both businesses and developed its industrial computer business through
nationwide advertising.

         On August 1, 1994, the Company entered into an agreement to purchase
all of the issued and outstanding shares of Industrial Data Systems, Inc., in a
tax-free exchange of Common Stock. The Company issued 9,500,000 shares of its
Common Stock to William A. Coskey and Hulda L. Coskey, with each individual
beneficially holding 4,750,000, respectively. At the time 


                                      1

<PAGE>

of acquisition, William A. Coskey and Hulda L. Coskey beneficially held all 
of the issued and outstanding shares of the Common Stock of Industrial Data 
Systems, Inc., a Texas corporation. William A. Coskey held the positions of 
Chairman of the Board, Chief Executive Office and President of Industrial 
Data Systems, Inc., and Hulda L. Coskey held the positions of Director, Vice 
President and Secretary/Treasurer of Industrial Data Systems, Inc. The 
executive officers, management team and beneficial ownership of securities 
held by the executive officers were the same in both companies at the time of 
the transaction.

         IDS is a provider of specialized microcomputer products that are
targeted to be sold to the industrial market. IDS manufactures, provides systems
integration and resells industrial and portable computers, microcomputers and
color CRT monitors. The microcomputer and peripheral products are designed to be
used in industrial applications, which include manufacturing, process control,
discrete manufacturing, data acquisition, telecommunications and man-machine
interfaces. The computers and monitors that are manufactured by the Company are
different from conventional, commercial desktop and portable computers by their
architecture, packaging, functionality, integration services and value-added
software. The computer products manufactured by IDS are "open systems" that
support "off-the-shelf" software operated under DOS or Windows.

         IDS seeks to add value to standard computer components by packaging
these components in enclosures that withstand tough environmental conditions
and/or enclosures that have a special form factor. IDS also seeks to add value
by integrating and technically supporting advanced microcomputer systems.

IED

         On October 15, 1997 the consulting engineering segment of the Company,
formerly known as Industrial Data Systems, Inc. doing business as IDS
Engineering, was incorporated in the State of Texas and now operates as IED. The
Company issued all of its 1,000 shares of Common Stock to Industrial Data
Systems Corporation. William A. Coskey was appointed Chairman of the Board,
President and Treasurer of IED and Hulda L. Coskey was appointed the positions
of Director, Vice President and Secretary of the newly formed corporation. The
management structure and operations of the newly formed corporation remain
unchanged. The Company believes that the restructuring of IED more clearly
distinguishes it from the Company's other operating segments.

         IED offers engineering services to major integrated oil and gas
companies. These services are performed on facilities that include cross-country
pipelines, pipeline pump stations, compressor stations, metering facilities,
underground storage facilities, tank storage facilities and product loading
terminals. The management team of IED has the capability of developing a project
from the initial planning stages through detailed design and construction
management. The services provided include project scoping, cost estimating,
engineering design, material procurement, mechanical fabrication, in addition to
project and construction management.

         IED has blanket service contracts currently in place to provide
services on a time and materials reimbursable basis. IED also performs services
for its clients on a turnkey lump sum 


                                      2

basis. The Company has long standing relationships with several major oil and 
gas pipeline companies. New business relationships with other major oil 
companies are developed through in-house personnel.

THERMAL

         The Company acquired Thermal Corp. (Thermal) on February 15, 1997. The
Company issued 600,000 shares of Common Stock which were held in an escrow
account pending completion of the acquisition by the Company exercising its
option to pay $600,000 and obtain a release of the shares. The Company's option
to acquire Thermal was later renegotiated and exercised on February 14, 1997
with the exchange of 193,719 shares of Common Stock and $212,563 in cash. Upon
completion of the acquisition, the 600,000 shares of Common Stock previously
included in the original Escrow Agreement were canceled. In connection with this
transaction, Thermal purchased its previously leased facilities on February 28,
1997 for a cash consideration of $500,000, subject to the completion of the
contingent purchase transaction. Bank financing in the amount of $450,000 was
obtained for the purpose of purchasing these facilities.

         Mr. Joe Hollingsworth, the former President and owner, acquired the 
industrial air handling subsidiary assets of a predecessor business known as 
Thermal Engineering ("Old Thermaire") in 1972, and operated the Company until 
1990, at which time Old Thermaire was sold to 20th Century Holding Company, 
as a wholly owned subsidiary. 20th Century Holding Company encountered 
financial difficulties and filed for protection under the bankruptcy laws in 
July 1992. The assets of Old Thermaire were placed in receivership and Mr. 
Hollingsworth reacquired these assets in October 1992, with the intention of 
continuing the company in its present form. Thermal was incorporated on 
November 17, 1992 for this purpose.

         Throughout its history, Thermal has built a reputation in the
commercial and industrial air handling industry for its quality products which
are distributed throughout the United States.

CPM

         On February 19, 1998, the Company signed a letter of intent to acquire
CPM, a Texas corporation formed in June, 1989. The acquisition was consummated
on March 25, 1998 with the exchange of 300,000 shares of the Company's Common
Stock for 100% of CPM's shares. CPM's previous owner, Jack Ripley, has remained
with CPM as Vice President of Sales and Marketing under an employment contract.
CPM's previous Sales Manager, Tilden Smith, has remained with CPM in the same
position under an employment contract.

         CPM is a thirteen-year-old company firmly established in the
uninterruptible and conditioned power systems marketplace. CPM manufactures
proprietary products and packages systems in a wide array of power ranges which
include: battery chargers and monitoring systems, DC power supplies, DC/AC
inverters, uninterruptible power systems, regulation and isolation transformers
and power conditioners. CPM sells to industrial and commercial accounts across
the United States.

IDS FAB

         Effective November 1, 1998, the Company acquired MLC Enterprises, Inc.,
a Texas corporation formed on August 7, 1995, doing business as Marine and
Industrial Fire & Safety (MIFS) and Marine and Industrial Supply Company (MISC).
As agreed upon in the Stock Acquisition Agreement, the Company issued 50,000
shares of Common Stock and cash consideration of $100,000 in exchange for 100%
of MLC's shares. Immediately following the acquisition, the name of the company
was changed to IDS FAB and will continue to do business as MIFS. It is the
Company's intention to sell or otherwise dispose of the MISC portion of IDS FAB.
IDS FAB's previous owner, Michael Moore, has remained with IDS FAB as
Managing Director and Vice President of Sales under an employment contract.

         IDS FAB operates in the fire safety, fabrication and oil-field supply
marketplaces. It's primary operating division, MIFS, designs, manufactures,
fabricates and distributes specialized safety equipment to petroleum related
facilities which are both offshore and onshore. MISC is an oil-field supplier
specializing in pipe, valves and fittings for the drilling and production
industry which primarily sells to one account.

PRODUCTS AND SERVICES

         IDS

         IDS provides Intel microprocessor-based microcomputer systems and
system components that are extremely dependable and can withstand harsh weather
conditions and demanding work environments. These computer systems are designed
to withstand a wide fluctuation in temperatures, shock waves, vibration,
electromagnetic and radio frequency interference, in addition to airborne dust
particles and excessive moisture. IDS also provides microcomputer systems that
are packaged into enclosures which have special form factors.

         The SafeCase Series 4000 is a proprietary design of IDS and its 
primary product. The SafeCase Series 4000 is a durable, rugged portable 
computer designed to be operated under extremely harsh environmental 
conditions normally encountered at industrial and commercial locations. The 
computer is constructed with a four slot passive backplane and three 
full-size open bus slots to allow the user to customize it with industry 
standard add-in boards. These computers are designed with dual cooling fans 
to control heat build-up, are fully gasketed to prevent the penetration of 
moisture and dust particles, and has a shock mounted disk drive which 
together enhance its service life. The locations and sites under which these 
computers are generally operated are unlike the environmental conditions 
under which the plastic notebook and laptop computers are operated. To 
complement the durability of the SafeCase Series 4000, its sturdy aluminum 
carrying case has been designed to withstand excessive mechanical loads.

         IDS also derives revenue from the systems integration and resale of
industrial computer products manufactured by other companies. These products are
typically designed with enclosures that withstand tough environmental conditions
and/or with enclosures that have a special form factor. In the area of systems
integration and resale, IDS designates three series of industrial computer
products and systems. The SafeCase Series 3000 represents industrial
microcomputer systems which are suitable for installation in a standard 19 inch
equipment rack. 


                                      4

<PAGE>

The SafeCase Series 5000 represents color CRT computer monitor products which 
are available in 14 inch, 17 inch and 20 inch diagonal models. The SafeCase 
Series 7000 represents industrial microcomputer systems which are designed to 
be mounted on a wall or attached to machinery or other equipment.

         In 1996, the Company announced the introduction of the SafeCase Series
400 computer as its latest entry into the industrial portable computer market.
This computer was specified to be the industrial equivalent of a commercial
grade notebook computer. Primarily as a result of the compact nature of the
proposed design, IDS encountered technical problems during the product design
phase, which resulted in significant project delays. The Company felt it did not
have sufficient technical resources to complete this product. In addition, the
Company believed that the resulting higher cost of the product would limit its
marketability. Therefore, IDS entered into an agreement with a major customer to
license the manufacturing rights for the SafeCase Series 400 limiting the sale
of this product only in their marketplace. IDS also simultaneously sold this
customer all product related inventory at cost. The value of this product
licensing and inventory sale transaction was approximately $350,000. At the
present time, IDS does not intend to further pursue design or production of the
SafeCase Series 400 product.

         IED

         IED offers engineering services to the pipeline division of major
integrated oil companies. These services are performed on facilities that
include cross-country pipelines, pipeline pump stations, compressor stations,
metering facilities, underground storage facilities, tank storage facilities and
product loading terminals. The management team of IED has the capability of
developing a project from the initial planning stages through detailed design
and construction management. IED's expertise offers its clients a wide range of
services from a single source provider. The services provided include project
scoping, feasibility studies, cost estimating, engineering design, material
procurement, mechanical fabrication, analyzing and implementing automation and
control systems, along with project and construction management. Typical
engineering projects include revamps or expansions of existing pipelines as well
as new construction.

         THERMAL

         Thermal has manufactured quality air handling equipment since 1945.
Because Thermal stocks a larger number of fans and manufactures coils, dampers,
curbs and most other accessories, it aims to offer the quickest delivery
available in the industry, usually six to eight weeks, depending on order size
and scope. Thermal also reserves production capacity to accomplish premium,
expedited deliveries of two to four weeks, when necessary. Thermal is well known
for its design and manufacturing expertise and flexibility which is often
required to meet the special needs for custom installations. Thermal's product
lines consist of a variety of cooling, heating and ventilating equipment. The
wide range of sizes and models in each product line coupled with Thermal's
manufacturing flexibility provides vast freedom in air handling equipment
choice. Thermal's quality air handling products include central plant air
conditioners, multizone air conditioners, high pressure air conditioners, and
air cooled condensers. Thermal also manufactures fan coil units, cooling and
heating coils, and roof


                                      5

<PAGE>

top air handlers. Thermal distributes its products exclusively through its 
United States and international network of non-stocking sales representatives.

         Central plant air handlers can be built to specification in either a
single or multizone configuration, from 1,000 to 50,000 cubic feet per minute
(CFM). The design of these units allows for either horizontal or vertical
applications. Single wall models are constructed in modular sections and double
wall units feature unitized construction. Basic designs and high quality
materials have been field-proven for over fifty years. The welded frame
construction allows panels to be removed without affecting the structural
integrity of the unit. All units are built using heavy gauge, galvanized panels
on die-formed and welded galvanized steel frames. On double wall insulated
units, the most often specified design, all wall panels and doors are fully
gasketed and removable. All fans are statically and dynamically balanced during
assembly. Custom features include but are not limited to view glass windows,
factory applied epoxy and custom coatings, variable pitch drives, internal motor
base with spring isolators, solid or stainless steel fan shafts, spiral or plate
fin coils, motor and unit controls, filter gauges, and convenience outlets.

         Rooftop air handlers can be built to specification in either a single
or multizone configuration, from 1,000 to 32,000 CFM. Standard features for all
rooftop air handlers include a structural channel base, galvanized steel frame,
galvanized steel panels, pitched roof with continuous ridge cap and integral
drip ledge, 2 to 1.5 pounds per cubic foot (pcf) insulation, double inlet double
width fan and open drip proof motor mounted on 1 foot deflection spring
isolators, 2 foot 30% pleated filters and pitched, double wall drain pan. Custom
units can feature plenum fan, gravity economizer, internal piping vestibule
motor controls and special base designed for field rollproof unloading.

         CPM

         CPM designs, manufactures, and sells standard and custom back-up and
conditioned power systems including battery chargers, battery monitors, DC power
supplies, converters, inverters, uninterruptible power systems, regulation and
isolation transformers, power conditioners, power distribution systems and solar
photo-voltaic systems. Additionally, CPM provides field service support for
installation and maintenance of these products. Most of the products
manufactured by CPM are made pursuant to specifications required for a
particular order. The products sold by CPM are utilized by refineries,
petrochemical plants, utilities, offshore platforms and other commercial,
industrial and governmental facilities.

         IDS FAB

         IDS FAB designs, engineers and fabricates fire protection systems and
equipment for the energy and marine industries worldwide, through the MIFS
portion of the business. Systems and equipment manufactured by MIFS includes
foam skids, CO2 suppression systems, deluge systems, fire pumps, oscillating
fire monitors and remote controlled fire monitors. MIFS also distributes fire
protection products manufactured by other companies, including Chubb, Kidde,
Akron and Elkhart. MIFS also fabricates process piping and skids which are not
related to the fire protection industry, but are utilized by MIFS's energy and
marine 


                                      6

<PAGE>

customers. MIFS provides field service support for installation and

by MIFS are made pursuant to specifications required for a particular order. 
The products and systems sold by MIFS are utilized by refineries, 
petrochemical plants, offshore drilling rigs, offshore production platforms 
and other industrial facilities. MISC, the oilfield supply portion of the 
business, buys and resells oilfield equipment, primarily to one account.

PRODUCT DEVELOPMENT

         IDS

         IDS is currently not developing any new proprietary product designs. In
order to satisfy customer requirements, IDS makes frequent modifications to its
proprietary SafeCase 4000 design. Revisions also are being made to this product
to increase functionality and reduce cost. Being an integrator and re-seller of
industrial microcomputer systems, IDS is continuously evaluating products in its
marketplace which serves to increase its range of offerings and enhance its
ability to sell systems to its customers. In this activity, IDS evaluates
microcomputer enclosures, CPU boards, components and peripheral products from a
variety of manufacturers.

         IED

         IED continues to provide engineering services to the pipeline industry
as its base of business. During 1998, IED signed two new blanket service
contracts with pipeline industry clients. In February 1999, the Company
announced the opening of a satellite office in Tulsa, Oklahoma which will
facilitate the expansion of its market area. IED plans to increase its range of
engineering capabilities and begin marketing its services to new industries such
as the refining, petrochemical and process industries.

         THERMAL

         During 1998, Thermal redesigned their line of rooftop air handlers in
order to increase capacity and provide for a narrower unit to better fit
shipping platforms and reduce freight costs. Thermal also was successful in
obtaining Environmental Testing Laboratories certification for its products,
which will open new markets for its products to municipalities and other
industries requiring such certification. During 1999, Thermal plans to add the
in-house capability of manufacturing industry certified plate-fin coils with
0.625 inch diameter tubing. Thermal believes the addition of this plate-fin coil
production line will improve its competitive position in the marketplace by
reducing product costs and production time. Thermal currently purchases all
plate-fin coils from outside sources.

         CPM

         CPM is currently in the developmental stages of designing a proprietary
battery monitor product. The proposed product will continuously monitor
parameters associated with battery systems, including current, voltage and
temperature. The battery monitor will provide status and historical information
about the battery system to which it is connected, and also will have a 


                                      7

<PAGE>

feature to optimize recharging. In 1999, CPM will also be redesigning some of 
its existing charger line in order to improve cost effectiveness as well as 
to decrease manufacturing time required to produce these products.

         IDS FAB

         IDS FAB currently has no products or services under development.

COMPETITION

         IDS

         IDS competes against various companies across its different product
lines. IDS' line of industrial portable computers compete with products
manufactured by Fieldworks, Dolch and Panasonic. IDS' industrial computer
products which are mountable in a 19 inch equipment rack compete with products
from Advantek, Contec and Industrial Computer Source. There is also competition
from much larger suppliers of commercial grade computers, such as Compaq, Dell,
Toshiba and IBM. This commercial competition effectively sets pricing for its
product line, since IDS' customers are willing to pay a premium for industrial
grade computers which is usually limited to approximately two times the
equivalent of commercial grade products.

         Management believes that its industrial computer products compete
effectively based on its engineering responsiveness to specific industrial
market requirements, the resulting functional specialization of its products,
and its strategy of focusing on relatively "sheltered" market niches where major
competitors have difficulty tailoring their offerings to specific application
requirements. These strategies help offset the greater name recognition and
broader service and support resources of IDS' major competitors.

          IDS is engaged in business activities that are targeted to industrial
  markets which are less competitive and typically generate greater profit
  margins. Management believes that the principal competitive factors in the
  business in which it operates are price and performance, product availability,
  technical expertise, adherence to industry standards, financial stability,
  service support and reputation. Pricing competition for IDS' products is from
  large manufacturers of commercial grade computer products. IDS' pricing of its
  computer product line is governed by pricing in the commercial market.

         Some of the IDS' current and potential competitors have longer
operating histories and financial, sales, marketing, manufacturing,
distribution, technical and other competitive resources which are substantially
greater than those of IDS. As a result, IDS' competitors may be able to adapt
more quickly to changes in customer demands or to commit resources to sales and
service of its products than IDS has available. Such competitors could also seek
to increase their presence in the markets where IDS is providing sales and
services by creating strategic alliances with other competitors, by offering new
or improved products and services to IDS' customers or increasing their efforts
to gain and retain market share through competitive pricing.

         IED

         IED operates in a highly competitive environment with many other
organizations which are substantially larger and have greater financial and
other resources. IED competes with other consulting engineering companies on the
basis of price, performance, and its experience as a provider of quality
personnel to perform projects. The pricing competition of IED has intensified as
a result of an increase in temporary personnel contracting agencies who can
perform services at a higher volume level and lower profit margin. Because the
engineering business may require small amounts of capital, market entry can be
rather effortless for a potential new competitor possessing acceptable
professional qualifications. Therefore, IED competes with a wide array of both
national and regional specialty firms.

         THERMAL

         Thermal operates in a highly competitive environment with many other
organizations which are substantially larger and have greater financial
resources. Management believes that the principal competitive factors in its
market include time to market, flexibility and design of its products, breadth
of product features, product quality, customer service, and price. Thermal
competes with other air handling equipment manufacturers on the basis of
quality, quick delivery and its capability to provide custom applications.
Thermal is cost competitive with many well respected manufacturers, such as
Pace, Temtrol, and Buffalo. Thermal has distinguished itself by being responsive
to customer requests for custom products and is able to expedite delivery of
these units faster than other commercial manufacturers due to the flexibility of
their manufacturing facility and staff.

         CPM

         CPM is engaged in a highly competitive business which is characterized
by a small number of larger companies that dominate the bulk of the market and a
large number of similarly sized companies that compete for a limited share of
the market. In the opinion of management, the competitive position of CPM is
dependent on the ability of to provide quality products to a customer's
specifications, on a timely basis, at a competitive price, utilizing
state-of-the-art materials, design and production methods. Some of CPM's
principal competitors are larger and have greater capital and management
resources. However, management believes that it can capitalize on its ability to
provide custom packaged systems more effectively than its competition.

         IDS FAB

         IDS FAB's business is also highly competitive. IDS FAB competes with a
variety of industrial and safety supply distributors, many of which may have
greater financial and other resources than IDS FAB. IDS FAB competes not only
with companies of similar size selling to customers within the same geographic
area but also with much larger distributors that provide integrated supply
programs and outsourcing services which may be able to supply their products in
a more efficient and cost-effective manner than does IDS FAB. However, IDS FAB
remains competitive through its product application, engineering and fabricating
expertise offered by its professional staff and it's after-the-sale services
provided by IDS FAB.

BUSINESS STRATEGY

         IDS intends to increase market penetration by focusing on systems
integration and the resale of industrial microcomputer products that are
manufactured by outside sources. IDS believes that it does not have the
personnel or financial resources to broaden its line of proprietary industrial
computer products. In addition, the Company believes that an effort to develop a
broad line of proprietary industrial computer products cannot be financially
justified, given the rapid pace of change and resulting short product lifetimes
typical of the computer industry. IDS will seek to add value by integrating and
technically supporting advanced microcomputer systems primarily comprised of
components from outside sources. IDS has continued to develop and expand its
market presence in the eastern and mid-western portion of the United States
since the opening of its sales office in Connecticut in 1997.

         IED's strategy is to increase revenues per employee by developing and
marketing the capability of performing turnkey or EPC (Engineering, Procurement
and Construction) projects. IED has traditionally only been responsible for the
engineering portion of its projects, which is normally between five to fifteen
percent of the project's total installed cost. On the majority of projects to
date, IED has invoiced for hours worked by its personnel with billing rates that
are specified in client generated blanket services contracts. In order to
execute this EPC strategy, IED will have to greatly enhance its project proposal
and bidding capability. In the first quarter of 1999, IED has hired two people
with extensive EPC project proposal experience. While executing this EPC
strategy, IED plans to expand its area of engineering expertise beyond its
traditional focus on the pipeline industry. IED plans to market its services and
submit proposals outside of the pipeline industry, which over a period of time,
will serve to diversify its client base.

         Thermal continues to focus on establishing and supporting a qualified
sales representative network within the U.S. The planned addition in 1999 of a
plate-fin coil manufacturing line will help reduce product costs and production
time.

         CPM plans to expand its marketing activities beyond the Texas-Gulf
Coast region. As of February 1999, CPM has signed contracts with three sales
representative firms outside of this region. CPM is focusing on obtaining a
reliable source for industrial quality uninterruptible power supply (UPS)
systems. CPM is currently evaluating this marketplace and plans to either
strategically align itself with an outside UPS supplier or initiate its own UPS
design project.

         With the expansion of IED's project scope into the EPC arena, it is
anticipated that increased opportunities will arise for growth in the IDS FAB
subsidiary through the cross-selling of fabrication services.

         The Company also intends to continue to pursue potential acquisitions
of complementary businesses. The success of this strategy depends not only upon
the Company's ability to acquire complementary businesses on a cost-effective
basis, but also upon its ability to integrate acquired operations into its
organization effectively, to retain and motivate key personnel and to retain
customers of acquired firms. There can be no assurance that the Company will be
able to find 


                                      10

<PAGE>

suitable acquisition candidates or be successful in acquiring or integrating 
such businesses. Furthermore, there can be no assurance that financing 
required for any such transactions will be available on satisfactory terms.

SALES AND MARKETING

         The Company's various subsidiaries derive revenues from in-house direct
sales, sales representatives and catalog distributor sales. IDSC's products are 
primarily marketed through commissioned third-party sales representatives. 
These sales representatives are teamed with in-house sales managers and are 
assigned to territories within the United States. Management believes that this 
method of selling leads to increased account penetration, proper management of 
its products, and enhanced customer service which create and maintain the 
foundation for long-term relationships with its customers. The Company's 
in-house sales personnel are normally compensated utilizing incentive 
commissions which are based on either a percentage of revenues or gross 
profitability which can be attributed to their efforts. Management believes that
its past and future growth depends in large measure on its ability to attract
and retain qualified sales representatives and sales management personnel.

         The Company's subsidiaries promote their products and services through
general and trade advertising, participation in trade shows and through
telemarketing and most recently through on-line Internet communication via
IDSC's corporate home page which provides links to each of the subsidiaries
webpages. Much of the Company's business is repeat business, and the source of
new customers has been largely through word-of-mouth referrals from existing
customers and industry members, such as manufacturer's representatives.

         The Company's sales personnel focus on building long-term relationships
with customers and, through their product and industry expertise, providing
customers with product application, engineering and after-the-sale services.
Additionally, the sales personnel of IDSC subsidiaries seek to capitalize on
customer relationships that have been developed by each subsidiary through
cross-selling of the various products and services offered by each subsidiary.
Sales leads developed by this synergy are then jointly pursued.

CUSTOMERS

         IDSC's customer base consists primarily of Fortune 500 companies in
numerous industry segments within the United States.

         The Company's largest ten customers (which varied from period to
period) accounted in the aggregate for approximately 77% and 63% of the
Company's total revenue during 1997 and 1998, respectively.

         Currently, the Company's major customers include:
IDS:       Baker Hughes Inteq, SAIC

IED:       EXXON Pipeline Co., Marathon Pipeline Co., Jacobs Engineering
THERMAL:   Hollingsworth Equipment, South Texas Equipment
CPM:       Powell Equipment, Gulf Interstate


                                      11

<PAGE>

IDS FAB:   Baker Hughes Processing, Chevron, Amfels, Texaco

         Based upon historical results and existing relationships with
customers, the Company believes that although efforts are being made to
diversify its client base, a substantial portion of its total revenue and gross
profit will continue to be derived from sales to existing customers. There are
no long-term commitments by such customers to purchase products or services from
the Company. Sales of IDSC's subsidiaries products are typically made on a
purchase order basis. A significant reduction in orders from any of the
Company's largest customers could have a material adverse effect on the
Company's financial condition and results of operations. Similarly, the loss of
any one of the Company's largest customers or the failure of any one of such
customers to pay its accounts receivable on a timely basis could have a material
adverse effect on the Company's financial condition and results of operations.
There can be no assurance that the Company's largest customers will continue to
place orders with the Company or that orders by such customers will continue at
their previous levels. There can be no assurance that the Company's customers
for its engineering services will continue to enter into contracts with the
Company for such services or that existing contracts will not be terminated.

CUSTOMER SERVICE AND SUPPORT

         The Company provides service and technical support to its customers in
varying degrees depending upon the product line and on customer contractual
arrangements. The Company's support staff provides initial telephone
troubleshooting services for end-user customers and distributors. These services
include isolating and verifying reported product failures, authorizing product
returns and tracking completion of repaired goods in support of customer
requirements. Technical support also provides on-site engineering support in the
event that a technical issue can not be resolved over the telephone. The Company
provides limited warranty coverage for its products for varying time periods
depending on a variety of factors.

DEPENDENCE UPON SUPPLIERS

         The Company's businesses depend upon the ability to obtain an adequate
supply of products and parts at competitive prices and on reasonable terms. The
Company's suppliers are not obligated to have products on hand for timely
delivery to the Company nor can they guarantee product availability in
sufficient quantities to meet the Company's demands. There can be no assurance
that such products will be available as required by the Company at prices or on
terms acceptable to the Company. The Company procures a majority of its
components from distributors in order to obtain competitive pricing, maximize
product availability and maintain quality control.

         In some cases, IDS' computer components are purchased through a single
source. IDS does not always have a long term purchasing contract in place to
purchase computer components from single sources. In the normal course of
business, IDS executes blanket purchase orders with its major suppliers for a
period of one year in order to maintain competitive pricing and service. The
purchase orders include provisions for the delivery, on a monthly basis, of an
adequate supply of computer parts to fulfill the Company's orders for a period
of one year


                                      12

<PAGE>

         IDS purchases from other manufacturers substantially all peripheral
devices and components used in its products and systems. A majority of the
components and peripherals are available from a number of different suppliers,
although certain major items are procured from single sources. Management
believes that alternate sources could be developed for such single source items,
if necessary, however, in the event that certain peripheral or component
shortages were to occur, it could have an adverse effect on IDS' operations.

         The business in which IDS competes is characterized by rapid
technological change and frequent introduction of new products and product
enhancements. IDS' success depends in large part on its ability to identify and
obtain products that meet the changing requirements of the marketplace. IDS
could experience delays in the receipt of these integral products. There can be
no assurance that IDS will be able to identify and offer products necessary to
remain competitive or avoid losses related to obsolete inventory and drastic
price reductions. IDS attempts to maintain a level of inventory required to meet
its near term delivery requirements by relying on the ready availability of
products from its principal suppliers. Accordingly, the failure of IDS'
suppliers to maintain adequate inventory levels of computer products demanded by
its existing and potential customers and to react effectively to new product
introductions could have a material adverse affect on the Company's financial
condition and results of operations. Failure of IDS to gain sufficient access to
new products or product enhancements could also have a material adverse affect
on the Company's financial condition and results of operations.

         Thermal currently stocks key components due to long lead times. Fans
are purchased on individual purchase orders. Thermal has increased its stocking
level of this component, because of the potential delays in manufacturing which
would be caused by its inability to procure this important element.

         All of CPM's products are manufactured using components and materials
that are readily available from numerous domestic suppliers. CPM has
approximately ten principal suppliers of components and each of those could be
replaced with several competitors; therefore, CPM anticipates no difficulty in
obtaining components in sufficient quantities and in a timely manner to support
its manufacturing and assembly operations.

         IDS FAB acquires its products through numerous original equipment
manufacturers, fabricators and distributors. The company believes that
alternative sources of supply could be obtained in a timely manner if any of
these relationships were canceled. The Company does not believe that the loss of
any one of these relationships with its distributors would have a material
adverse effect on the financial condition or results of operations of IDS FAB.
Representative manufacturers of products distributed by IDS FAB include Chubb,
Kidde, Keystone Valve, Elkhart and Akron.

         There can be no assurance that IDSC's subsidiaries will be able to
continue to obtain the necessary components from any of its single sources on
terms acceptable to the Company, if at all. There can be no assurance that such
relationships will continue or that, in the event of a termination of its
relationship, it would be able to obtain alternative sources of supply without a
material disruption in the Company's ability to provide products to its
customers. Any material disruption in the Company's supply of products would
have a material adverse effect on the 


                                      13

<PAGE>

Company's financial condition and results of operations. No one manufacturer 
or vendor provides products that account for 10% or more of the Company's 
revenues.

PATENTS, TRADEMARKS, LICENSES

         The Company's success depends in part upon its proprietary technology,
and it relies primarily on trade secrecy and confidentiality agreements to
establish and protect its rights in its proprietary technology. The Company does
not own the rights to any U.S. or foreign patents. There can be no assurance
that the Company's present protective measures will be adequate to prevent
unauthorized use or disclosure of its technology or independent third party
development of the same or similar technology. Although the Company's
competitive position could be affected by its ability to protect its proprietary
and trade secret information, the Company believes other factors, such as the
technical expertise and knowledge of the Company's management and technical
personnel, and the timeliness and quality of support services provided by the
Company, to be more significant in maintaining the Company's competitive
position.

       The Company currently has no patents, trademarks, licenses or royalty
agreements.

GOVERNMENT REGULATIONS

         Certain of the Company's subsidiaries are subject to various laws and
regulations relating to its business and operations, and various health and
safety regulations as established by the Occupational Safety and Health
Administration. The Company is not currently aware of any situation or condition
that it believes is likely to have a material adverse effect on its results of
operations or financial condition.

RESEARCH AND DEVELOPMENT

         Research and development cost for 1998 was $25,049. 1997 expenditures
for research and development was $148,259. As of December 31, 1998 there were no
ongoing research and development activities.

EMPLOYEES

         As of December 31, 1998, the Company employed approximately 135
individuals within its five subsidiaries; approximately twelve were employed in
sales, marketing and customer services; fifty-one were employed in engineering;
fifty-four were employed in technical production positions; and seventeen were
employed in administration, finance and management information systems. The
Company believes that its ability to recruit and retain highly skilled and
experienced technical, sales and management personnel has been, and will
continue to be, critical to its ability to execute its business plan. None of
the Company's employees are represented by a labor union or are subject to a
collective bargaining agreement. The Company believes that relations with its
employees are good.

ITEM 2.  DESCRIPTION OF PROPERTY

FACILITIES

         Except as noted below, the Company leases its principal executive
offices in Houston, Texas, which consist of approximately 20,525 square feet
that has been divided into administrative, sales, and engineering offices.
Approximately 12,000 square feet of this space is currently utilized for
production operations and warehouse space for the IDS and CPM operations. On
September 1, 1998 the Company leased 2,370 square feet of adjoining office space
for expansion of its' IED operation. As a result of this expansion, a fourth
amendment of its lease was executed which extended the lease to August 31, 2002.

         On February 10, 1999, IED signed a lease for its newly established
office in Tulsa, Oklahoma. This office space consists of 5,400 square feet in a
one-story office building. The lease is for a term of two years, ending on
February 28, 2001. The base monthly rent is $2,925. with an additional Common
Area fee of $225. per month. Management believes that it has the ability to
sustain substantial additional sales growth without having to expand its
facilities or relocate its offices.

         As a result of the acquisition of Thermal, the land and property
previously leased by Thermal was purchased by Thermal for $500,000, consisting
of $50,000 cash advance from the Company and a note payable in the amount of
$450,000. The balance on this note at December 31, 1998 was $420,830. This
property consists of 4.5995 acres of land improved with a 37,725 square foot
concrete tiltwall office/manufacturing facility located in Houston, Texas.
Thermal owns and occupies a 37,735 square foot facility on approximately 4.5
acres which consists of approximately 2,500 square feet of office space and
35,200 square feet of manufacturing area located in Houston, Texas.

         As a result of the acquisition of CPM, the Company was able to allocate
a portion of its available space occupied by IDS to serve as office and
manufacturing space for the CPM. In consolidating its facilities, the Company
was successful in reducing overhead and increasing operating efficiencies by
vacating the existing space leased by CPM.

         The newly acquired, IDS FAB subsidiary leases a 12,650 square foot
office/warehouse building situated on approximately 25,000 square feet of land
in Houston, Texas. The term of the lease is three years from December 1, 1997
and ending on November 30, 2000 unless sooner terminated. A deposit in the
amount of $3,795.00 for the last month's rent was paid in advance. This facility
serves as the IDS FAB's sales office, warehouse, and fabrication plant. From
time to time, IDS FAB subleases property adjacent to its fabrication facility on
an as-needed basis to facilitate implementation of large projects. At year-end
1998, IDS FAB was the sublessor of 16,500 square feet of office/warehouse space.
The term of the sublease was for three months from October 8, 1998 and ending
January 8, 1999 unless sooner terminated at a monthly rate of $4,950. The
sub-lease was renewed for a ninety (90) day period terminating March 8, 1999.

         At the time of the acquisition by the Company, IDS FAB had additional
leased office/warehouse space of approximately 3,915 square feet in Houston,
Texas. The operations of 


                                      15

<PAGE>

the two business units had been consolidated into the existing lease space 
occupied by the MIFS unit leaving this space unoccupied. The original term of 
the lease was for 36 months beginning December 15, 1996 and ending December 
14, 1999; however, IDSC was able to negotiate a Lease Termination Agreement 
that allowed for early termination of the lease effective November 18, 1998 
for payment of $1,570. By doing so, the Company was successful in reducing 
overhead and increasing operating efficiencies.

ITEM 3.  LEGAL PROCEEDINGS

         From time to time, the Company is involved in various legal proceedings
arising in the ordinary course of business. The Company is not currently
involved in any material legal proceedings and is not aware of any legal
proceeding threatened against it.

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

         No matters were submitted to a vote of the Company's stockholders
during the fourth quarter of the fiscal year ended December 31, 1998.

earnings, capital requirements, operating and financial position and general
business conditions. The Company intends to retain any future earnings for
reinvestment in its business and does not intend to pay cash dividends in the
foreseeable future. The Company has not entered into any agreement which
restricts its ability to pay dividends on its Common Stock in the future. See

ITEM 6.  MANAGEMENT'S DISCUSSION AND ANALYSIS OR PLAN OF OPERATION

         The following discussion is qualified in its entirety by, and should be
read in conjunction with, the Company's Consolidated Financial Statements
including the Notes thereto, included elsewhere in this Annual Report on Form
10-KSB/A. Footnote 12 to the Financial Statements contains segment information.

OVERVIEW

         The Company was formed in 1985 to engage in the business of providing
engineering consulting services to the pipeline divisions of major integrated
oil and gas companies. For the period from 1985 through 1989, most of its
revenues were derived from the IED segment. In 1989, the Company introduced its
Industrial Products segment and has continued to introduce new products to the
marketplace. In 1997, with the acquisition of Thermal, the Company expanded into
the manufacture and distribution of air handling equipment for HVAC systems. The
Products segment has generated sales as a percent of total revenue of 24.5% and
11.4%, for 1997 and 1998, respectively, while the Engineering segment has
generated sales as a percent of total revenue of 40.5% and 32.8% for the same
periods. The Air Handling segment has generated sales as a percent of total
revenue of 34.9% and 27.6%, for 1997 and 1998, respectively. In 1998, with the
acquisition of CPM, the Company expanded into the manufacture and distribution
of uninterrupitable power systems and battery charger units and with the
acquisition of IDS FAB, the Company expanded into the design and fabrication of
fire detection, fire prevention equipment, environmental and safety equipment.
The Power Systems segment generated sales as a percent of total revenue of 22.5%
for the nine months ended December 31, 1998, and the Fabricating segment
generated sales as a percent of total revenue of 5.7% for the two month period
ended December 31, 1998.

         The gross margin varies between each of its operating segments. The
Product segment has produced a gross margin ranging from 31.4% in 1997 to 20.2%
in 1998 due to the decrease in sales volume between 1997 and 1998. The gross
margin for Engineering segment which reflects direct labor costs, has ranged
from 24.5% in 1997 to 28.7% in 1998. The gross margin produced by the Air
Handling segment decreased from 20.4% in 1997 to 19.3% in 1998. The Power
Systems segment produced a gross margin in 1998 of 30.7%. The Fabricating
segment produced a gross margin of (17.1%) for a two-month period ended December
31, 1998. The overall gross margin for IDSC, which includes Products,
Engineering and Air Handling was 24.8% in 1997. The 1998 overall gross margin
which includes Products, Engineering, Air Handling, Power Systems for nine
months and Fabricating for two months was 23.0%.

YEAR 2000 (Y2K) ISSUES AND CONSEQUENCES

         The Company's program to address its Year 2000 issues has progressed 
as planned. Testing of the Company's internal hardware systems has been 
completed and all systems have been brought into Y2K compliance. Upgrading of 
non-compliant software systems is underway and will be completed by the end 
of the third quarter of 1999. Costs expended to address Year 

                                    18


<PAGE>

2000 issues has been approximately $50,000 and an estimated additional 
$200,000 will be spent to correct Year 2000 issues. The cost to address these 
issues is being funded from internally-generated cash flow and are expensed 
as incurred.

         The Company does not own or maintain any computer controlled machinery
or operations outside its primary offices and production facilities, which would
be effected by non-complaint Y2K components.

         Over the past three years, the Company has required Y2K compliant
components on all parts procured for its manufacturing process and has received
certification from the manufacturers and suppliers to this effect. The Company
does not rely heavily upon any single vendor for goods and services and does not
have significant suppliers or vendors who share information systems.

         The Company's program to deal with Year 2000 issues includes evaluation
of the effects of third-party non-compliance and the effect that non-compliance
would have on the Company's ability to do business. The Company has banking
relations with one major financial institution, which has indicated that they
are Y2K compliant. The Company does not believe that the inability of external
agents to complete their Year 2000 remediation process in a timely manner will
have a material effect on the financial position or results of operation of the
Company. No material adverse effects have been identified, but the Company
intends to continue its evaluation process throughout the 1999 year. However, 
the effect of non-compliance by external agents is not readily determinable.

         There can be no guarantee that the Company's current efforts or its
contingency plan will successfully address all the contingencies that may arise.
The Company has defined critical activities which would be maintained manually
in case third party utility failures, such as electrical and telephone
systems. In the event the Company is unsuccessful in addressing all its Year
2000 issues, there could be material adverse effect on the Company's financial
condition and liquidity. Disruptions in the economy generally resulting from
Year 2000 issues could adversely effect the Company's ability to do business.
The amount of potential liability or lost revenue cannot be reasonably estimated
at this time.

</TABLE>

YEAR ENDED DECEMBER 31, 1998 COMPARED TO YEAR ENDED DECEMBER 31, 1997

     TOTAL REVENUE. Total revenue increased by $2,908,848 or 27.6% from 
$10,523,977 in 1997 to $13,432,825 in 1998. Revenue from the Products 
segment, which comprised 24.5% and 11.4% of total revenue in 1997 and 1998, 
respectively, decreased by $1,045,718 or 40.5%. The decrease in Products 
segment revenue was generally attributable to the overall decline in sales 
due to lack of sales initiative in 1998. Revenue from the Enginneering 
segment, which comprised

                                      20

<PAGE>

40.3% and 32.8% of total revenue in 1997 and 1998, respectively, increased by 
$141,139 or 3.3%. This slight increase was due to the segment adding lump-sum 
projects to its existing scope of jobs performed. Revenue from the Air 
Handling segment comprised 24.9% and 27.6% of total revenue in 1997 and 1998, 
respectively, increased by $30,774 or .8%. No sales were recorded in 1997 for 
the Power Systems segment or the Fabricating segment, since each was acquired 
during 1998. The Power Systems segment contributed $3,016,286 to the total 
revenue in 1998 during the nine months from April 1 to December 31, 1998, and 
IDS FAB contributed $766,367 to the total revenues during the two months from 
November 1 to December 31, 1998.

         GROSS PROFIT. Gross profit increased by $478,477 or 18.4% from
$2,605,797 in 1997 to $3,084,724 in 1998. The gross margin for the Products 
segment decreased from 31.4% in 1997 to 20.2% in 1998. This decrease was 
attributable to the overall decline in sales revenue without offsetting 
reductions in production costs. The gross margin for the Engineering segment 
increased from 24.6% in 1997 to 28.7% in 1998. This increase was attributable 
to changes in the scope of jobs being performed generating higher margins, 
plus the addition of lump-sum projects being added to the product line of 
jobs performed by the segment. The gross margin for the Air Handling segment 
decreased slightly from 20.4% in 1997 to 19.3% in 1998. This decrease was due 
to general competition in the market. The Power Systems segment generated a 
gross margin of 30.7% for 1998. The Fabricating segment's gross margin for 
1998 was a negative 17.1%.

         SELLING, GENERAL AND ADMINISTRATIVE EXPENSES. Selling, general and
administrative expenses increased by $288,190 or 15.1% from $1,914,818 in 1997
to $2,203,008 in 1998. As a percentage of total revenue, selling, general and
administrative expenses decreased from 18.2% in 1997 to 16.4% in 1998. The
increase was attributable to the acquisitions of CPM and IDS FAB which added
additional personnel costs and increased overall general and administrative
expenses. The increases were more than offset by the increased revenue generated
by the additional operations.

         OPERATING INCOME. Operating income increased by $116,824 or 19.7% 
from $593,878 in 1997 to $710,702 in 1998. Operating income decreased as a 
percentage of total revenue from 5.6% in 1997 to 5.3% in 1998. This decrease 
was brought about by the lower gross margins in the Products segment, in the 
Air Handling segment and the effect of the negative gross margin in the 
Fabricating segment.

         NET INCOME. Net income after taxes increased by $37,337 or 9.8% from
$382,495 in 1997 to $419,832 in 1998. Net income after taxes decreased as a
percentage of total revenue from 3.6% in 1997 to 3.1% in 1998.

LIQUIDITY AND CAPITAL RESOURCES

         Historically, the Company has satisfied its cash requirements 
principally through operations and as needed by borrowing under its line of 
credit. As of December 31, 1998, the Company's cash position, including 
marketable securities, was, in management's judgment sufficient to meet its 
working capital requirements. The Company had, as of December 31, 1998, 
$1,150,000 in additional advances available under its line of credit with a 
bank. This line of credit provides for maximum borrowings of $1,150,000, 
which bears interest at prime plus 1% 

                                      21

<PAGE>


is for a term of one year and matures on May 12, 1999. The Company expects 
the line of credit will be renewed at that time. The line of credit is 
secured by accounts receivable, inventory and the personal guarantees of 
certain stockholders and officers of the Company. The Company has an 
additional term note maturing May 12, 1999, in the amount of $375,000 and 
bears interest at prime plus 1%. This note also is secured by accounts 
receivable, inventory and the personal guarantees of certain stockholders. 
Interest on the outstanding balance of this note is paid on a monthly basis. 
At its maturity on May 12, 1999, the Company expects that the line of credit 
term note will be renewed.

         The Company believes that it has sufficient working capital and does
not intend to sell shares of its Common Stock within the next twelve months.

         The Company's working capital was $2,790,559 and $3,047,291 at December
31, 1997 and December 31, 1998, respectively.

         CASH FLOW

         Operating activities provided (used) net cash totaling ($818,061) 
and $551,975 during 1997 and 1998, respectively. The Company has not 
generated significant cash flow from operating activities due to the working 
capital requirements resulting from its rapid growth. Trade accounts 
receivable over the prior year increased $1,301,632 and decreased $660,162 
for the years ended December 31, 1997 and 1998, respectively. Inventory 
increased by $300,149 and decreased $177,745 for the same periods.

         Investing activities used cash totaling $1,066,995 and generated
$208,515 respectively, during the years ended December 31, 1997 and 1998. In
1997, the Company's investing activities that used cash were primarily related 
to the acquisition of Thermal and capital expenditures. In 1998, the Company's
investing activities were executed primarily with the common Stock of the 
Company for the acquisition of CPM and IDS FAB.

         As of December 31, 1998, the Company had a portfolio of marketable
securities with a fair market value of $676,647 and consisted of bonds and
mutual funds. The mutual funds that the Company owns are open-end stock funds
managed by Aim, Pioneer, and Smith Barney & Co. These mutual fund investments
are generally held for longer than one year. These securities are traded by the
Company as part of its plan to provide additional cash for working capital
requirements.

         The marketable securities to be held until maturity are stated at
amortized cost. Marketable securities classified as available-for-sale are
stated at market value, with unrealized gains and losses reported as a separate
component of stockholder's equity, net of deferred income taxes. If a decline in
market value is determined to be other than temporary, any such loss is charged
to earnings. Marketable securities accounted for as trading securities are
stated at market value, with unrealized gains and losses charged to income.
William A. Coskey, the Company's President and Chief Executive Officer, is
responsible for managing the Company's portfolio of marketable securities. The
funds used in this portfolio were from generally available cash reserves.

                                      22

<PAGE>


         The Company has implemented a policy that restricts it from purchasing
any securities on margin, and also limits the investment of any one security or
mutual fund to represent no more than 10% of the Company's investment portfolio.
The Company believes that the risks associated with its investment portfolio are
slightly higher than the risk of loss in a Standard & Poor's 500 Index Fund.
This higher risk is due to the less diverse distribution of the Company's
portfolio as compared to the broadly based Standard & Poor's 500 Stock Index.

         Financing activities provided cash totaling $1,367,657 and $7,630
during 1997 and 1998. During 1997, $811,929 was provided from the collection of
notes receivable that were received as consideration for sales of Common Stock
in 1996. Additionally, financing activities provided an increase in borrowings
of $554,913 under its line of credit. The Company has additional financing
amounts available on its line of credit ($1,150,000 at December 31, 1998 and at
March 30, 1999). The line of credit has been used principally to finance
accounts receivable and inventory purchases. Additional bank financing in the
amount of $450,000 was obtained for the purchase of the facilities that Thermal
had been leasing.

         ASSET MANAGEMENT

         The Company's cash flow from operations has been affected primarily by
the timing of its collection of trade accounts receivable. The Company typically
sells its products and services on short-term credit terms and seeks to minimize
its credit risk by performing credit checks and conducting its own collection
efforts. The Company had trade accounts receivable of $2,268,864 and $2,193,128
at December 31, 1997 and 1998, respectively. The number of days' sales
outstanding in trade accounts receivable was 78 days and 70 days, respectively.
Bad debt expenses have been insignificant (approximately .01%) for each of these
periods.

Board of Directors and Stockholders
Industrial Data Systems Corporation

We have audited the accompanying consolidated balance sheet of Industrial Data
Systems Corporation and Subsidiaries as of December 31, 1998, and the related
consolidated statements of income and comprehensive income, stockholders' equity
and cash flows for the years ended December 31, 1998 and 1997. These
consolidated financial statements are the responsibility of the Company's
management. Our responsibility is to express an opinion on these consolidated
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 audits to obtain
reasonable assurance about whether the consolidated financial statements are
free of material misstatement. An audit includes examining, on a test basis,
evidence supporting the amounts and disclosures in the consolidated financial
statements. An audit also includes assessing the accounting principles used and
significant estimates made by management, as well as evaluating the overall
financial statement presentation. We believe that our audits provide a
reasonable basis for our opinion.

In our opinion, the consolidated financial statements referred to above present
fairly, in all material respects, the consolidated financial position of
Industrial Data Systems Corporation and Subsidiaries as of December 31, 1998,
and the results of their operations and their cash flows for the years ended
December 31, 1998 and 1997, in conformity with generally accepted accounting

                                AND SUBSIDIARIES
                   NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

1.      ORGANIZATION AND SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

        ORGANIZATION - The accompanying consolidated financial statements
        include the accounts of Industrial Data Systems Corporation ("IDSC" or
        the "Company"), a Nevada corporation, and its wholly-owned subsidiaries
        Industrial Data Systems, Inc., a Texas corporation, dba IDS Technical
        Services ("IDS"); Thermaire, Inc., a Texas corporation, dba Thermal
        Corporation ("Thermal"); Constant Power Manufacturing, Inc. ("CPM"), a
        Texas corporation, IDS Engineering, Inc. ("IED"), a Texas corporation;
        and IDS Fabricated Systems, Inc. ("IDS FAB"), a Texas corporation. All
        significant intercompany balances and transactions have been eliminated
        in consolidation.

        CASH AND CASH EQUIVALENTS - Cash and cash equivalents include cash in
        bank and investments in highly liquid money market mutual funds.

        INVENTORY - Inventory is composed primarily of raw materials and
        component parts (computer components, sheet metal, copper tubing, blower
        fans and fan motors) and is carried at the lower of cost or market
        value, with cost determined on the first-in, first out ("FIFO") method
        of accounting.

        REVENUE RECOGNITION - The Company's revenues are composed of product
        sales and engineering service revenue. The Company recognizes service
        revenue when such services are performed and product sales upon shipment
        to the customer.

        MARKETABLE SECURITIES - Marketable securities to be held to maturity are
        stated at amortized cost. Marketable securities classified as
        available-for-sale are stated at market value, with unrealized gains and
        losses reported as a separate component of stockholders' equity, net of
        deferred income taxes. If a decline in market value is determined to be
        other than temporary, any such loss is charged to earnings. Trading
        securities are stated at fair value, with unrealized gains and losses
        recognized in earnings. The Company records the purchases and sales of
        marketable securities and records realized gains and losses on the trade
        date. Realized gains or losses on the sale of securities are recognized
        on the specific identification method.

        PROPERTY AND EQUIPMENT - All property and equipment is stated at cost,
        adjusted for accumulated depreciation. Depreciation on all property and
        equipment, other than land, building and improvements, is calculated
        using an accelerated method over the estimated useful lives of the
        related assets, which is five years. Depreciation on the building is
        calculated using a straight-line method over the useful life, which is
        40 years. Leasehold improvements are amortized over the term of the
        related lease.

                                AND SUBSIDIARIES
                   NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

        GOODWILL - The Company capitalizes the excess purchase price over the
        fair value of net assets acquired ("goodwill") and amortizes this
        intangible asset on a straight-line basis over 5-10 years.

        LONG-LIVED ASSETS - The Company reviews for the impairment of long-lived
        assets and certain identifiable intangibles whenever events or changes
        in circumstances indicate that the carrying amount of an asset may not
        be recoverable. An impairment loss would be recognized when estimated
        future cash flows expected to result from the use of the asset and its
        eventual disposition is less than its carrying amount. The Company has
        not identified any such impairment losses.

        INCOME TAXES - The Company accounts for deferred income taxes in
        accordance with the asset and liability method, whereby deferred income
        taxes are recognized for the tax consequences of temporary differences
        by applying enacted statutory tax rates applicable to future years to
        differences between the financial statement and tax bases of its
        existing assets and liabilities. The provision for income taxes
        represents the current tax payable or refundable for the period plus or
        minus the tax effect of the net change in the deferred tax assets and
        liabilities during the period.

        EARNINGS PER SHARE - Basic earnings per share was computed by dividing
        net income by the weighted average common shares outstanding as of
        December 31, 1997 and 1998. There were no dilutive securities at
        December 31, 1997 and 1998.

        USE OF ESTIMATES - The preparation of the Company's consolidated
        financial statements in conformity with generally accepted accounting
        principles requires the Company's management to make estimates and
        assumptions that affect the amounts reported in these financial
        statements and accompanying results. Actual results could differ from
        these estimates.

        SIGNIFICANT ESTIMATE - The Company's management has made significant
        estimates related to the realizability of the Company's goodwill
        associated with the acquisition of IDS FAB (see Note 14). The estimation
        process involved in determining if assets have been impaired is
        inherently uncertain since it requires estimates of current market
        yields as well as future events and conditions, which could change these
        estimates in the near term.

        FAIR VALUE OF FINANCIAL INSTRUMENTS - The fair value of financial
        instruments, primarily accounts receivable, accounts payable and notes
        payable, closely approximate the carrying values of the instruments due
        to the short-term maturities of such instruments.

                   NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

        COMPREHENSIVE INCOME - Comprehensive income is defined as all changes in
        stockholders' equity, exclusive of transactions with owners, such as
        capital investments. Comprehensive income includes net income or loss,
        changes in certain assets and liabilities that are reported directly in
        equity, such as translation adjustments on investments in foreign
        subsidiaries and certain changes in minimum pension liabilities.

        RECLASSIFICATIONS - Amounts in prior years' financial statements are
        reclassified as necessary to conform with the current year's
        presentation. Such reclassifications had no effect on net income.

        The Company assumed a term note payable with a bank of $200,000 bearing
        interest at 6.9% as part of the acquisition of IDS FAB (see Note 14).
        This note, which expires on June 25, 1999, is collateralized by a

7.      PROFIT SHARING PLAN

        The Company has a 401(k) profit sharing plan (the "Plan") covering
        substantially all employees. Under the terms of the Plan, the Company
        will make matching contributions equal to 50% of employee contributions
        up to 3% of employee compensation, as defined. Employees may make
        contributions up to 15% of their compensation, subject to certain
        maximum contribution limitations. The employer's contributions vest on a
        schedule of 25% per year for four years. The Company made contributions
        to the Plan of $72,000 and $93,000 for the years ended December 31, 1997
        and 1998, respectively.

8.      CONCENTRATION OF CREDIT RISK AND MAJOR CUSTOMERS

        The Company manufactures and distributes industrial and portable
        computers and computer monitors, power systems and battery chargers, and
        air handling equipment for air conditioning and heating systems to
        commercial companies primarily in the southern states and provides
        pipeline engineering and fabricated systems and services primarily to
        major integrated oil and gas companies. The Company performs ongoing
        credit evaluations of its customers and generally does not require
        collateral. The Company assesses its credit risk and provides an
        allowance for doubtful accounts for any accounts which it deems doubtful
        for collection.

        The Company maintains deposits in banks which may exceed the amount of
        federal deposit insurance available. Management periodically assesses
        the financial condition of the institutions and believes that any
        possible deposit loss is minimal.

        For the year ended December 31, 1997, the Company had sales to five
        major customers in the Engineering and Thermal segments totaling
        approximately $6,630,000, representing 63% of total revenues for the
        year. For the year ended December 31, 1998, the Company had sales to one
        major customer in the Engineering segment totaling approximately
        $2,533,000 which represents 19% of total revenues. At December 31, 1998,

        Company paid $600,000, consisting of $212,563 in cash and 193,719 shares
        of the Company's common stock, which may have been put back to the
        Company for $2 per share at the option of the holder. Additionally, the

                                AND SUBSIDIARIES
                   NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

        In management's opinion, the unaudited proforma combined results of
        operations are not indicative of the actual results that would have
        occurred had the acquisitions been consummated at the beginning of
        fiscal 1997 or of future operations of the combined companies under the
        ownership and management of the Company.

14.     YEAR 2000

        The Year 2000 problem is the result of computer programs being 
        written using two digits rather than four to define the applicable 
        year.  Any programs that have time-sensitive software may recognize a 
        date using "00" as the year 1900 rather than the year 2000.  This 
        could result in a major system failure or miscalculations.  The Year 
        2000 problem may impact or be impacted by other entities with which 
        the Company transacts business.

        The Company has begun to address possible remedial efforts in connection
        with computer software that could be affected by the Year 2000 problem.
        The Company has incurred approximately $50,000 of remediation costs 
        and estimates another $200,000 will be incurred toward remediation of 
        the Year 2000 problem.  Such costs are expensed as incurred.
