                               PROSPECTUS SUMMARY
 
    THE FOLLOWING SUMMARY IS QUALIFIED IN ITS ENTIRETY BY THE MORE DETAILED
INFORMATION AND THE CONSOLIDATED FINANCIAL STATEMENTS AND NOTES THERETO
APPEARING ELSEWHERE IN THIS PROSPECTUS. INVESTORS SHOULD CAREFULLY CONSIDER THE
RISK FACTORS RELATED TO THE PURCHASE OF COMMON STOCK OF THE COMPANY. SEE "RISK
FACTORS."
 
                                  THE COMPANY
 
   
    Total Control Products, Inc. ("Total Control" or the "Company") designs,
develops and markets products and technology for the control segment of the
industrial automation market. The Company's broad range of products are used to
define, monitor and maintain the operation, sequencing and safety of industrial
equipment and machinery on the factory floor. These products range from closed
architecture programmable logic controller ("PLC") operator interfaces to open
architecture control software and systems, and are sold primarily through an
international network of independent distributors with over 200 sales locations.
End-users of the Company's products include Abbott Laboratories, The Boeing
Company, The Coca-Cola Company, The Dow Chemical Company, Eastman Kodak Company,
Ford Motor Company, General Motors Corporation, Nabisco, Inc. and USX
Corporation.
    
 
    The market for control segment products has been dominated by large
manufacturers selling proprietary products. These proprietary products have many
inherent limitations including fixed, vendor-defined functionality, closed
architectures and limited networking capabilities, all of which result in a high
cost of ownership. The Company believes that a migration is occurring gradually
in this marketplace towards open systems-based products. Open systems allow
manufacturers to benefit from standard networking protocols, intuitive graphical
user interfaces, enhanced application software functionality and the continued
cost reductions and performance increases associated with standards-based
products. Furthermore, the availability of a standardized, easy-to-support
operating system, such as Windows NT, allows industrial automation products to
be based upon an open architecture platform with widespread market acceptance.
 
   
    To serve the diverse needs of this marketplace, the Company offers a broad
range of control segment products. The Company's principal product line,
QuickPanel and similar products, has gained a leadership position in the
operator interface market and accounted for over 62% of the Company's net sales
in the nine months ending December 31, 1996. The Company believes that this
product line delivers price/performance leadership and has allowed the Company
to gain greater visibility and an enhanced reputation both with its independent
distributors and with end-users. The Company is beginning to invest substantial
resources in developing future generations of the QuickPanel product line aimed
at giving it the functionality of an open standards, interoperable network
computer.
    
 
    The Company believes that industrial automation products for the control
segment are best marketed and sold through independent distributors. The Company
seeks to establish and maintain relationships with the leading industrial
automation distributors in each of the geographic areas in which it competes.
The Company's strategy for growth includes expanding its network of distributors
as well as continuing to develop products that, from price, performance and
support perspectives, satisfy the selling requirements of its distributors.
 
    The industrial automation marketplace continues to be highly competitive and
fragmented and the Company believes that opportunities exist to acquire
companies, assets and product lines which will allow it to expand its product
portfolio and to leverage its operating infrastructure and distributor network.
In September 1996, the Company acquired a controlling interest in Taylor
Industrial Software Inc. ("Taylor"), a developer of PC-control software,
client/server program management software, graphical operator interface software
and PLC configuration and support software (the "Taylor Transaction"). In
January 1996, the Company acquired Cincinnati Dynacomp, Inc. ("Cincinnati"), a
manufacturer of lower-end operator interface products (the "Cincinnati
Transaction").
 
    The Company believes that its broad product line, its international network
of independent distributors and its substantial base of end-users position it to
become a leading worldwide provider of products in the control segment of the
industrial automation market.

                                  RISK FACTORS
 
    THE FOLLOWING RISK FACTORS SHOULD BE CONSIDERED CAREFULLY IN ADDITION TO THE
OTHER INFORMATION IN THIS PROSPECTUS BEFORE PURCHASING THE COMMON STOCK OFFERED
BY THIS PROSPECTUS.
 
    QUARTERLY VARIATIONS IN OPERATING RESULTS.  Results of the Company's
operations have fluctuated from quarter to quarter in the past, and may
fluctuate significantly in the future. Such fluctuations may result from a
variety of factors, including the timing of new product introductions by the
Company, its competitors or third parties, the loss of any of its significant
distributors, currency fluctuations, disruption in the supply of components for
the Company's products, changes in product mix or capacity utilization, the
timing of orders from major customers, personnel changes, production delays or
inefficiencies, seasonality and other factors affecting sales and results of
operations. Such quarterly fluctuations in results of operations may adversely
affect the market price of the Common Stock. A substantial portion of the
Company's sales for each quarter results from orders received in that quarter.
Consequently, the Company is dependent upon obtaining orders for shipment in a
particular quarter to achieve its sales objectives for that quarter.
Furthermore, the Company has often recognized a substantial portion of its sales
in the last month of a quarter, with sales frequently concentrated in the last
weeks or days of a quarter. A substantial portion of the Company's operating
expenses are primarily related to personnel, development of new products,
marketing programs and facilities. The level of spending for such expenses
cannot be adjusted quickly, and is based, in significant part, on the Company's
expectations of future revenue. If actual revenue levels are below management's
expectations, the Company's business, financial condition and results of
operations may be materially adversely affected. The Company believes that
period-to-period comparisons of its results of operations are not necessarily
meaningful and should not be relied upon as indicators of future performance.
 
   
    DEPENDENCE UPON DIGITAL ELECTRONICS CORPORATION.  The Company is
substantially dependent upon its relationship with Digital Electronics
Corporation, a corporation located in Osaka, Japan ("Digital Electronics"),
which is the Company's sole supplier of the flat panel displays that are the
principal hardware component incorporated in the graphics-based operator
interface products that represent the Company's best selling product line. For
fiscal 1994, 1995 and 1996 and for the nine months ended December 31, 1996,
sales from this product line accounted for 45.9%, 61.9%, 70.7% and 62.1%,
respectively, of the Company's net sales. The Company has no contractual
arrangement obligating Digital Electronics to continue to supply these
components to the Company or setting prices for the purchase of these
components. The inability of the Company to obtain this hardware platform from
Digital Electronics, significant delays or shortages in production or
significant price increases by Digital Electronics would have a material adverse
effect on the Company. The Company currently has no identified alternative
supplier for the products supplied by Digital Electronics. Although the Company
has the exclusive right in North and South America to market and distribute all
hardware products manufactured by Digital Electronics pursuant to the terms of a
distribution agreement, which expires in April 2005, there can be no assurance
that Digital Electronics will continue to manufacture such products. At any
time, Digital Electronics could become a direct competitor of the Company
outside of North and South America and, upon expiration of the distribution
agreement in April 2005, Digital Electronics could become a direct competitor of
the Company in North America and South America. The Company is also dependent on
the ability of Digital Electronics to continue to develop its hardware
technology to meet rapidly changing customer requirements and competing
technologies. The Company is currently engaged in certain product development
efforts with Digital Electronics which are important to the Company's future
strategic position. The historic business relationship between the Company and
Digital Electronics has been based to a significant extent on personal
relationships between members of the management of the two companies and the
previous dealings of the entities. If those relationships were to change, or if
the management of the Company or Digital Electronics were to change, this could
result in a material adverse effect on the relationship between the Company and
Digital Electronics and, in turn, on the business, financial condition and
results of operations of the Company. The Company believes that the relationship
    
 
                                       6
<PAGE>
   
between Digital Electronics and the Company has been and remains good. However,
there can be no assurance that the relationship will continue on a satisfactory
basis. Digital Electronics is not affiliated with Digital Equipment Corporation.
Digital Electronics is also a shareholder of the Company and Taylor, and has
certain other relationships with the Company. See "Recent Acquisitions -- Taylor
Transaction" and "Certain Transactions."
    
 
   
    DEPENDENCE ON DISTRIBUTORS.  The Company derives substantially all of its
revenue from sales of its products through its network of distributors. The
Company expects that sales through its distributors will continue to account for
a substantial portion of its revenue for the foreseeable future. In particular,
sales to one distributor, McNaughton-McKay Electric Company, accounted for
13.9%, 9.5% and 8.7% of the Company's net sales in fiscal 1995 and 1996 and the
nine months ended December 31, 1996, respectively. None of the Company's
distributors are under the control of the Company or sell the Company's products
on an exclusive basis, and there can be no assurance that future sales by
distributors will continue at present levels or increase. Each of the Company's
distributors may cease marketing the Company's products with limited notice and
with little or no penalty. There can be no assurance that the Company's
independent distributors will continue to offer the Company's products, or that
the Company will be able to recruit additional or replacement distributors. The
loss of one or more of the Company's major distributors could have a material
adverse effect on the Company's business, financial condition and results of
operations. Many of the Company's distributors offer industrial automation
products that compete with products offered by the Company. For example, the
Company believes that approximately 25% of the Company's net sales for fiscal
1996 resulted from sales by distributors that also offer products manufactured
by Allen-Bradley Co. ("Allen-Bradley"), a direct competitor of the Company.
There can be no assurance that the Company's distributors will give priority to
the marketing of the Company's products as compared to competitors' products.
Any reduction or delay in sales of the Company's products by its distributors
would have a material adverse effect on the business, financial condition and
results of operations of the Company.
    
 
   
    PRODUCT CONCENTRATION.  Sales from the Company's QuickPanel product and
similar products represented 70.7% and 62.1% of the Company's net sales in
fiscal 1996 and for the nine months ended December 31, 1996, respectively. The
Company expects that sales of these products will continue to account for a
substantial portion of the Company's net sales. Declines in demand for these
products, whether as a result of competition, technological change or otherwise,
would have a material adverse effect on the Company's business, financial
condition and results of operations. See "Business -- Products."
    
 
   
    CURRENCY EXCHANGE RATE FLUCTUATIONS.  The Company experiences foreign
currency exchange gains and losses in the ordinary course of its business due to
exchange rate fluctuations among a variety of currencies. Purchases of flat
panel screens from Digital Electronics, which constituted 61.1% and 47.4% of the
Company's cost of goods sold for fiscal 1996 and for the nine months ended
December 31, 1996, respectively, are transacted in Japanese Yen. As a result,
fluctuations in the exchange rate between the U.S. Dollar and the Yen may have a
material impact on the ability of the Company to maintain its gross margins. In
addition, Taylor is located in Edmonton, Alberta and, although most of its sales
are denominated in U.S. Dollars, most of its expenses are incurred in Canadian
Dollars. The Company currently attempts to hedge a portion of its potential risk
with respect to fluctuations in the Yen, and is investigating hedging Canadian
Dollars. While such foreign currency hedging transactions may moderate the
overall effect of currency fluctuations, the Company expects that such
fluctuations will continue, and there can be no assurance that the Company will
be successful in its hedging activities or that exchange rate fluctuations will
not otherwise have a material adverse effect on the Company's financial
condition or results of operations, or cause significant fluctuations in
quarterly results of operations.
    
 
    EFFECT OF RECENT ACQUISITIONS; RISKS ASSOCIATED WITH FUTURE
ACQUISITIONS.  In 1996, the Company acquired Cincinnati and a controlling
interest in Taylor (collectively, the "Acquired Businesses"). The
 
                                       7
<PAGE>
Company has no significant history of operations on a combined basis with either
of the Acquired Businesses. There can be no assurance that the Company will be
successful in integrating the operations and personnel of the Acquired
Businesses into its business, incorporating acquired technologies into its
product lines, establishing and maintaining uniform standards, controls,
procedures and policies, avoiding the impairment of relationships with employees
and customers as a result of changes in management or overcoming other problems
that may be encountered in connection with the integration of the Acquired
Businesses. Accordingly, the historical financial statements and pro forma
financial information presented in the Prospectus may not be indicative of the
results that would have been obtained had the acquisitions occurred on the date
assumed therein. In connection with the acquisition of the Acquired Businesses,
the Company recorded goodwill, which will be amortized over future periods, and
recognized certain one-time acquisition-related charges.
 
    A part of the Company's business strategy is to continue its growth through
strategic acquisitions. Identifying and pursuing future acquisition
opportunities and integrating acquired products and businesses will require a
significant amount of management time and skill. There can be no assurance that
the Company will be able to identify suitable acquisition candidates, consummate
any acquisition on acceptable terms or successfully integrate any acquired
business into the Company's operations. If the Company were to proceed with one
or more significant future acquisitions in which the consideration consists of
cash, a substantial portion of the Company's available cash (possibly including
a portion of the proceeds of this offering) could be used to consummate the
acquisitions. If the Company were to consummate one or more significant
acquisitions in which the consideration consists of stock, shareholders of the
Company could suffer a significant dilution of their interests in the Company.
Many business acquisitions must be accounted for as a purchase. Most of the
businesses that might become attractive acquisition candidates for the Company
are likely to have significant goodwill and intangible assets, and acquisition
of these businesses, if accounted for as a purchase, would typically result in
substantial goodwill amortization charges to the Company. In addition, such
acquisitions could involve acquisition-related charges. See "Selected
Consolidated Financial Data," "Management's Discussion and Analysis of Financial
Condition and Results of Operations," "Recent Acquisitions" and Unaudited Pro
Forma As Adjusted Condensed Consolidated Statements and the Notes thereto.
 
   
    EFFECT OF OBLIGATION TO MAKE CONTINGENT PAYMENTS.  Beginning in fiscal 1998,
the Company may become obligated under the terms of the Taylor Transaction and
the Cincinnati Transaction to make payments of contingent consideration which
could be substantial in amount. The Taylor Transaction requires contingent
payments based on Taylor's revenue for the twelve month periods ending September
30, 1997 and 1998, of up to $4.0 million for each of these twelve month periods.
The Cincinnati Transaction requires contingent payments based on calendar year
1997 revenues of Cincinnati-related product sales in excess of historic sales
volumes equal to 10.0% for the first $1.0 million of such excess and 4.0% of any
further excess. Additionally, the Cincinnati Transaction requires a contingent
payment equal to 1.25% of the Company's net sales in excess of $32.0 million for
each of the calendar years 1998, 1999 and 2000. Of such contingent payments with
respect to the Cincinnati Transaction, approximately half are payable in shares
of the Company's Common Stock valued at its fair market value at such time, with
the remainder payable in cash. The Company has a buy-out right with respect to
the contingent payments for the Cincinnati Transaction for the years 1998, 1999
and 2000, ranging from $1.0 million to $2.0 million depending on the timing of
the exercise of such right. These contingent payments may require the Company to
borrow against its existing credit facility or to seek additional equity or debt
financing, which could materially adversely affect the Company's business and
financial position. There can be no assurance that such capital will be
available to the Company on favorable terms, if at all. See "Recent
Acquisitions."
    
 
    RISKS OF SERVING CYCLICAL INDUSTRIES.  The end-users of the Company's
products include manufacturers in a number of industries which are cyclical in
nature, including the automotive and packaging industries. Such industries have
historically experienced periodic downturns as well as short-term
 
                                       8
<PAGE>
fluctuations which often have had an adverse effect on the demand for industrial
machinery and equipment in those industries and on the related demand for
products like those of the Company that are used to control such machinery and
equipment. Downturns in these industries could have a material adverse effect on
the Company's business, financial condition and results of operations.
 
    EFFECT OF RAPID GROWTH ON EXISTING RESOURCES.  The Company has grown rapidly
in recent years. A continuing period of rapid growth could place a significant
strain on the Company's management, operations and other resources. The
Company's ability to manage its growth will require it to continue to invest in
its operational, financial and management information systems, and to attract,
retain, motivate and effectively manage its employees. The inability of the
Company's management to attract such new employees and manage its growth
effectively could have a material adverse effect on the business, financial
condition and results of operations of the Company.
 
    TECHNOLOGICAL CHANGE; DIFFICULTIES AND RISKS ASSOCIATED WITH NEW PRODUCT
DEVELOPMENT AND INTRODUCTION.  The market for the Company's products is
characterized by rapidly changing technology, evolving industry standards and
frequent new product introductions. The Company's near-term success and future
growth are substantially dependent upon continuing market acceptance of its
existing products, and on the Company's ability to develop new products to meet
changing customer requirements and emerging industry standards. In addition, the
Company's growth is in part dependent on the ability of Digital Electronics to
maintain its development and supply of advanced hardware platforms for the
Company's graphics-based operator interface products. There can be no assurance
that products or technologies of the Company's competitors will not render the
Company's products or technologies noncompetitive or obsolete. The Company's
future success is dependent to a significant degree on its ability to develop
products in a timely manner that operate in an open architecture environment.
There can be no assurance that the Company will be successful in developing new
products or product extensions, that unanticipated problems or delays in future
development and production will not be encountered, or that, once developed, the
Company's products will meet the requirements of its customers or gain market
acceptance. See "Business -- Strategy," "-- Products," and "-- Product
Development."
 
    SIGNIFICANCE OF DEVELOPING MARKET.  The market for standards-based,
interoperable software tools and products in the industrial automation industry
is new and rapidly evolving. The Company's future success is dependent to a
significant degree upon broad market acceptance of the type of open architecture
products on which the Company is focusing its development efforts. There can be
no assurance that the market for such products will continue to develop or grow,
that the Company's product offerings will gain market acceptance, that the
Company will be able to offer in a timely manner, if at all, further product
developments utilizing open architecture technology or that the Company's
end-users will choose the Company's products for use. The failure of any of
these events to occur would have a material adverse effect on the business,
financial condition and results of operations of the Company. See "Business --
Strategy," "-- Products" and "-- Product Development."
 
   
    PARTIALLY OWNED SUBSIDIARY.  The Company owns 61.0% of the Class A Shares of
Taylor (the "Taylor Class A Shares"), and Digital Electronics owns the remaining
39.0% of such shares. Digital Electronics, as the minority shareholder of
Taylor, will be entitled to a portion of the economic benefits of the business
operated by Taylor and will have influence over the business and operations of
Taylor, including certain fundamental corporate transactions requiring
supermajority shareholder approval. Both the Company and Digital Electronics pay
a royalty to Taylor based on their sales of Taylor software products. Although
the Company owns a majority interest of the outstanding Taylor Class A Shares,
and although Taylor's financial results are consolidated with those of the
Company, the Company will not receive the full economic benefit from Taylor's
sales and operations. Moreover, the Company may not be able to unilaterally
control decisions regarding the conduct of Taylor's business and affairs.
    
 
                                       9
<PAGE>
    DEPENDENCE ON OUTSIDE SUPPLIERS.  The Company is dependent on outside
vendors to manufacture many of the components and subassemblies used in the
Company's products. Although substantially all of the components used in the
Company's products are available from multiple sources (other than the flat
panel screens supplied by Digital Electronics), the Company may experience
shortages in supply from its suppliers due to various factors, including
increases in market demand for certain components which occur from time to time
and the limited capacity of certain suppliers. The Company believes that the
partial or complete loss of one or more of its suppliers is not likely to have a
material long-term impact on its operations. Such a loss, however, could in the
short term result in significant production delays, require the Company to seek
alternative sources of supply and increase its cost of goods sold and,
therefore, could have a material adverse effect on the Company's business,
financial condition and results of operations.
 
    COMPETITION.  Competition in the industrial automation industry is intense
and characterized by rapidly advancing technologies. The Company faces
substantial competition in all of its product lines and competition may increase
if new competitors enter the market or if existing competitors expand their
product offerings. The Company believes that over time this competition may have
the effect of reducing average selling prices of comparable products offered by
competitors, and thus, in order to maintain sales, the Company may be forced to
increase unit volumes or increase the performance of its products in order to
offset or reduce any decreases in selling prices. In the event such price
reductions become necessary, the Company's ability to maintain gross margins
will depend on its ability to reduce its cost of goods sold in an amount
sufficient to compensate for any decreases in selling prices. Certain of the
Company's competitors and potential competitors have substantially greater name
recognition and financial, technical, marketing and other resources than the
Company. Such competitors or potential competitors may be able to exert leverage
or other competitive pressures on distributors to give priority to their own
products at the expense of the Company's products. To the extent the Company is
unable to compete effectively against its competitors, its business, financial
condition and results of operations could be materially adversely affected. The
Company believes its ability to effectively compete in the industrial automation
market depends on factors both within and outside its control, including the
ability of the Company to meet evolving market requirements, the timing and
success of new products developed by the Company and its competitors, product
performance and price, distribution and customer support, product reputation,
customers' assessment of the Company's financial resources and its technical and
service expertise. There can be no assurance that the Company will be able to
compete successfully with respect to these and other factors, and such
competitive pressures could adversely affect the Company's business, financial
condition and results of operations.
 
    PRODUCT LIABILITY EXPOSURE.  The use of the Company's products in systems
that interact directly on the factory floor, where the failure of the system
could cause substantial property damage or personal injury, could expose the
Company to significant product liability claims. Although the Company has not
experienced product liability claims to date, the sale and support of its
products may entail the risk of such claims. A successful product liability
claim brought against the Company, or product recall involving the Company's
products, could have a material adverse effect upon the Company's business,
financial condition and results of operations. The Company maintains product
liability insurance, but there can be no assurance that such insurance will be
sufficient to cover any claims or that it will continue to be available on
reasonable terms, if at all. The Company's contracts typically contain
limitations of liability, disclaimers of warranties, damage limitations, and
indemnifications against third party claims, which provisions may not be
effective in all circumstances and jurisdictions. Taylor's software license
agreements with its customers typically contain similar limitations and
provisions but consist of "shrink wrap" licenses that are not signed by
licensees and, therefore, it is possible that such licenses may be unenforceable
under the laws of certain jurisdictions.
 
    DEPENDENCE ON CHIEF EXECUTIVE OFFICER AND OTHER EXECUTIVE OFFICERS.  The
Company depends to a significant degree on its senior management and other
officers and key employees, especially its Chief
 
                                       10
<PAGE>
Executive Officer, Nicholas Gihl. The loss of Mr. Gihl's services, the loss of
service of one or more of the Company's other executive officers or the
inability to hire or retain qualified personnel could adversely affect the
Company's business, financial condition and results of operations. See
"Management."
 
   
    PROPRIETARY TECHNOLOGY AND PRODUCT PROTECTION; POTENTIAL INFRINGEMENT.  The
Company's success depends in part on its ability to maintain the proprietary and
confidential aspects of its products. The Company does not own any significant
patents, and relies on a combination of copyrights, non-disclosure agreements
with certain employees and other means to establish and protect its proprietary
rights. There can, however, be no assurance that the precautions taken by the
Company adequately protect the Company's technology. In addition, many of the
Company's competitors have obtained or developed, and may be expected to obtain
or develop in the future, patents, copyrights or other proprietary rights that
cover or affect products that perform functions similar to those performed by
products offered by the Company. The inability of the Company for any reason to
protect existing technology or otherwise acquire necessary technology could
prevent distribution or licensing of the Company's products, which would have a
material adverse effect on the business, financial condition and results of
operations of the Company. In addition, although the Company believes that its
products do not infringe patents, copyrights, or other proprietary rights of
third parties, there can be no assurance that the Company is aware of all
patents, copyrights or other proprietary rights that may be infringed by the
Company's products, that infringement does not exist or that infringement may
not be alleged by third parties in the future. If infringement is alleged, there
can be no assurance that the necessary licenses would be available on acceptable
terms, if at all, or that the Company would prevail in any related litigation.
Intellectual property litigation can be extremely protracted and expensive even
if the Company ultimately prevails, and involvement in such litigation could
have a material adverse effect on the business, financial condition and results
of operations of the Company. See "Business -- Intellectual Property."
    
 
    NO PRIOR PUBLIC MARKET FOR COMMON STOCK; POSSIBLE VOLATILITY OF STOCK
PRICE.  Prior to the offering contemplated hereby, there has been no public
market for the Common Stock, and there can be no assurance that an active public
market for the Common Stock will develop or be maintained after this offering.
The initial public offering price will be determined solely by negotiations
between the Company and the Underwriters, and may not bear any relationship to
the market price of the Common Stock after this offering. The stock market has
from time to time experienced extreme price and volume fluctuations, which often
have been unrelated to the operating performance of particular companies. Any
announcement with respect to any variance in net sales or earnings from levels
generally expected by securities analysts for a given period could have an
immediate and significant effect on the trading price of the Common Stock. In
addition, factors such as announcements of technological innovations or new
products by the Company, its competitors or other third parties, as well as
changing market conditions in the industrial automation industry, may have a
significant impact on the market price of the Common Stock. See "Underwriting."
 
    PREFERRED STOCK; STAGGERED BOARD AND ANTI-TAKEOVER EFFECTS OF CORPORATE
PROVISIONS.  The Board of Directors of the Company (the "Board of Directors")
has the authority to issue, without vote or action of the shareholders,
1,000,000 shares of Preferred Stock, no par value ("Preferred Stock"), in one or
more series; to fix the rights, preferences, privileges and restrictions
thereof, including dividend rights, conversion rights, voting rights, terms of
redemption, redemption prices and liquidation preferences; and to determine the
designation and the number of shares constituting any series. The issuance of
any Preferred Stock may have the effect of delaying, deferring or preventing a
change in control of the Company and may adversely affect the voting and other
rights of the holders of Common Stock. At present, the Company has no plans to
issue any Preferred Stock. The Company has also implemented a staggered Board of
Directors consisting of three three-year classes. These and other provisions in
the Company's Articles of Incorporation and By-laws and of Illinois law could
delay or make more difficult a merger, tender offer or proxy contest involving
the Company. See "Description of Capital Stock -- Certain Statutory Provisions"
and "-- Certain Charter and By-law Provisions."
 
                                       11
<PAGE>
    SHARES ELIGIBLE FOR FUTURE SALE.  Future sales of shares of Common Stock in
the public market after this offering could have a negative impact on the market
price of the Common Stock, and could adversely affect the Company's ability to
raise additional capital in the future. See "Shares Eligible for Future Sale."
 
   
    CONTROL BY EXISTING SHAREHOLDERS.  Upon the completion of this offering, the
current executive officers, directors and principal shareholders of the Company
will beneficially own approximately 52.7% of the outstanding shares of the
Common Stock of the Company. In addition, members of the Sparacino family,
including Julius J. Sparacino, the co-founder of the Company and the Chairman
Emeritus of the Board of Directors, his children and their spouses, including
Nicholas Gihl, the Chairman, President and Chief Executive Officer of the
Company, will own approximately 29.4% of the outstanding shares of the Common
Stock of the Company. Accordingly, such persons, if they act together, will have
effective control over the Company through their ability to control the election
of directors and all other matters that require action by the Company's
shareholders, irrespective of how other shareholders may vote. Among other
things, such persons could prevent or delay a change in control of the Company
which may be favored by a majority of the remaining shareholders. Such ability
to prevent or delay such a change in control of the Company also may have an
adverse effect on the market price of Common Stock. See "Management -- Executive
Officers and Directors" and "Principal and Selling Shareholders."
    
 
   
    DILUTION.  Investors who purchase shares of Common Stock in this offering,
at an assumed initial public offering price of $9.00 per share, will incur
immediate dilution in pro forma net tangible book value of $7.60 per share. See
"Dilution."

                                USE OF PROCEEDS
 
    The net proceeds to the Company from the sale of the 1,650,000 shares of
Common Stock offered by it hereby at an assumed initial public offering price of
$9.00 per share, after deducting the estimated underwriting discount and
estimated offering expenses payable by the Company, are estimated to be
approximately $13.1 million. The Company will not receive any proceeds from the
sale of shares by the Selling Shareholders in this offering.
 
   
    The Company intends to use the net proceeds of the offering to repay
approximately $13.1 million of indebtedness, consisting of (a) indebtedness of
approximately $5.6 million owed to certain shareholders of the Company, (b)
approximately $7.1 million of the outstanding balance of the Company's revolving
line of credit facility (which had a total outstanding balance of $7.4 million
as of December 31, 1996) and (c) other indebtedness of approximately $400,000.
The indebtedness to shareholders to be repaid includes the following
indebtedness incurred by the Company and Taylor in order to finance a portion of
the Taylor Transaction in September 1996, all of which will become due and
payable upon the closing of this offering: (i) a $2.2 million promissory note
payable by Taylor to Neil R. Taylor which bears interest at a rate of 12.5% per
annum until March 19, 1997, and 15.0% per annum thereafter, payable monthly,
(ii) a $2.0 million promissory note payable by the Company to A.B. Siemer which
bears interest at a rate of 20.0% per annum (13.0% of which is payable in cash
and 7.0% of which is payable in shares of Common Stock of the Company), payable
monthly after December 1996 and (iii) a $1.0 million promissory note payable by
the Company to Digital Electronics which bears interest at a rate of 5.0% per
annum, payable quarterly. Additionally, the shareholder indebtedness to be
repaid includes a $200,000 promissory note payable to Julius Sparacino, due
December 1997, bearing interest at 10.0%, and indebtedness of Taylor owed to Mr.
Taylor and his spouse of approximately $230,000, bearing interest at the
Canadian prime rate. See "Recent Acquisitions -- Taylor Transaction" and
"Certain Transactions."
    
 
    Any remaining net proceeds of the offering would be used by the Company for
working capital and other general corporate purposes, including potential future
acquisitions of products or businesses that expand, complement or otherwise
relate to the Company's current business and products. The Company does not
presently have any agreements or commitments with respect to any potential
acquisitions or investments, nor are any negotiations regarding any such
transactions ongoing. Pending any such uses, the Company will invest the net
proceeds in short-term, investment grade, interest-bearing securities.
 
                                DIVIDEND POLICY
 
   
    The Company has never declared or paid any cash dividends on its Common
Stock. The Company currently intends to retain future earnings, if any, to fund
the development and growth of its business and does not anticipate paying any
cash dividends in the foreseeable future. In addition, the Company's line of
credit facility includes covenants regarding maintenance of net worth, a net
worth to debt ratio and a cash flow ratio, which could be breached if a dividend
was declared, and therefore could have the effect of limiting the Company's
ability to pay cash dividends on its Common Stock.

was approximately $(20.0 million) or $(6.15) per share. The pro forma net
tangible book deficit of the Common Stock as of December 31, 1996 was
approximately $(2.4 million) or $(0.40) per share. The pro forma net tangible
book deficit per share represents the excess of the Company's total liabilities
over total tangible assets, divided by the total number of shares of Common
Stock outstanding, after giving effect to the Put Elimination, the Taylor
Conversion, the PIK Issuance and the Debenture Conversion.
    
 
   
    After giving effect to the sale by the Company of the 1,650,000 shares of
Common Stock offered hereby at an assumed initial public offering price of $9.00
per share, and the receipt of the net proceeds therefrom, the pro forma net
tangible book value of the Company (total tangible assets less total
liabilities) as of December 31, 1996 would have been approximately $10.7
million, or $1.40 per share. This represents an immediate increase in pro forma
net tangible book value of $1.80 per share to existing shareholders and an
immediate dilution in pro forma net tangible book value of $7.60 per share to
purchasers of Common Stock in this offering, as illustrated in the following
table:

    The foregoing table assumes no exercise of any stock options subsequent to
December 31, 1996, or the Underwriters' over-allotment option. As of December
31, 1996, an aggregate of 965,974 shares were reserved under the Company's stock
option plans, of which options to purchase an aggregate of 295,974 shares at a
weighted average exercise price of $2.85 per share were outstanding and options
to purchase 300,000 shares at an exercise price equal to the initial public
offering price per share will be granted immediately after the effectiveness of
this offering, and 250,000 shares of Common Stock were reserved for issuance
under the Company's discount stock purchase plan. To the extent such options are
exercised, there will be further dilution to new shareholders.
    
 
   
    The sale of shares by the Selling Shareholders in this offering will reduce
the number of shares held by existing shareholders to 4,903,576 shares, or
approximately 64.1% of the total number of shares of Common Stock outstanding
immediately after this offering (60.8% if the Underwriters' over-allotment
option is exercised in full), and will increase the number of shares held by new
shareholders to 2,750,000 shares, or 35.9% of the total number of shares of
Common Stock outstanding immediately after this offering (3,162,500 shares or
39.2% if the Underwriter's over-allotment option is exercised in full). See
"Principal and Selling Shareholders."

                      MANAGEMENT'S DISCUSSION AND ANALYSIS
                OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS
 
OVERVIEW
 
    The Company designs, develops and markets products and technology for the
control segment of the industrial automation market. The Company's broad range
of products are used to define, monitor and maintain the operation, sequencing
and safety of industrial equipment and machinery on the factory floor. These
products range from closed architecture PLC operator interfaces to open
architecture control software and systems, and are sold primarily through an
international network of independent distributors with over 200 sales locations.
End-users of the Company's products include Abbott Laboratories, The Boeing
Company, The Coca-Cola Company, The Dow Chemical Company, Eastman-Kodak Company,
Ford Motor Company, General Motors Corporation, Nabisco, Inc. and USX
Corporation.
 
   
    The Company's net sales include revenues from sales of products, software
license fees, software maintenance and services. The Company's principal product
line, QuickPanel and similar products, has gained a leadership position in the
operator interface market. It has been the Company's most successful product
line, accounting for 70.7% and 62.1% of net sales in fiscal 1996 and the nine
months ended December 31, 1996, respectively. This product line delivers
price/performance leadership and has allowed the Company to gain visibility and
enhance its reputation both with distributors and with end-users.
    
 
   
    A key element of the Company's strategy has been to expand the breadth of
products offered through its distributor network in order to maximize operating
leverage. In September 1996, the Company acquired a controlling interest in
Taylor, an Edmonton, Alberta-based developer of PC-control software,
client/server program management software, graphical operator interface software
and PLC configuration and support software. This acquisition expanded the
Company's product line, allowing it to capitalize on the growing trends towards
interoperable technology products, and gave the Company a platform from which to
develop new products incorporating this software technology into the Company's
traditional products. In January 1996, the Company acquired Cincinnati, which
strengthened the Company's product offerings in the lower-end of the operator
interface market. In connection with both of these acquisitions, the Company may
become obligated to make payments of contingent consideration which could be
substantial in amount. See "-- Liquidity and Capital Resources." Both of these
acquisitions were accounted for as a purchase in accordance with Accounting
Principles Board Opinion No. 16. In connection with the Taylor Transaction,
approximately $4.9 million was charged as an expense at the acquisition date
related to the purchase of incomplete research and development projects and
other acquisition costs. In connection with the Taylor Transaction and the
Cincinnati Transaction, the Company recorded approximately $2.5 million and $2.3
million, respectively, of goodwill (which will be increased in the event any
future contingent consideration is paid), which is being amortized on a
straight-line basis over 7 and 15 years, respectively. Following the Taylor
Transaction, the Company engaged a broker to commence the sale of Taylor's labor
scheduling software product line. The revenues, expenses and resulting net loss
associated with this product line since the date of acquisition have not been
reflected in the Company's statement of operations. See "Recent Acquisitions."
    
 
   
    All of the Company's purchases of flat panel displays are from Digital
Electronics and are transacted in Japanese Yen, while substantially all of the
Company's sales are in U.S. Dollars. These purchases from Digital Electronics
accounted for 61.1% and 47.4%, respectively, of the Company's total cost of
goods sold for fiscal 1996 and the nine months ended December 31, 1996. The
Company's financial performance, including its gross margin, may be
substantially impacted by changes in the Yen/Dollar exchange rate. The Company
attempts to hedge a portion of this exchange rate risk, but there can be no
assurance that the Company will be successful in its hedging activities or that
certain exchange rate fluctuations will not otherwise have a material adverse
effect on the Company's financial condition or results of operations, or cause
significant fluctuations in results of operations.

</TABLE>
    
 
   
NINE MONTHS ENDED DECEMBER 31, 1996 AND DECEMBER 31, 1995
    
 
   
    NET SALES.  Net sales increased 63.3% to $28.8 million for the nine months
ended December 31, 1996 compared to $17.6 in the comparable period of the prior
fiscal year. This increase resulted primarily from the growth in sales of the
Company's graphics-based operator interface products and from sales of products
acquired as a result of the Cincinnati Transaction. To a lesser extent, the
increase reflects the results of Taylor for the three months ended December 31,
1996 of approximately $2.0 million.
    
 
   
    GROSS PROFIT.  Cost of goods sold consists primarily of expenses for
components and subassemblies, subcontracted labor, direct labor, manufacturing
overhead, and provisions for excess and obsolete inventory. Gross profit
increased 92.9% to $13.6 million for the nine months ended December 31, 1996
from $7.1 million in the comparable prior period. Gross margin increased to
47.3% for the nine months ended December 31, 1996 from 40.0% in the comparable
prior period. This increase was attributable to a reduction in the material cost
primarily in the QuickPanel product line due to favorable Yen fluctuations,
partially offset by increases in direct labor and manufacturing overhead costs
as a percentage of sales related to the Cincinnati acquisition. In addition, the
Company benefited from three month's sales of higher gross margin Taylor
software products.
    
 
    SALES AND MARKETING.  Sales and marketing expenses consist primarily of
personnel costs, sales commissions paid to the Company's independent sales
representatives, advertising, product literature,
 
                                       20
<PAGE>
   
trade shows, distributor promotions and depreciation on equipment used for sales
related activities. Sales and marketing expenses increased 82.0% to $6.2 million
for the nine months ended December 31, 1996 from $3.4 million in the comparable
prior period. Approximately half of the increase resulted from increased
commissions due to higher sales volume, and increased advertising and
distributor promotional programs. Approximately $1.0 million of the increase
resulted from costs associated with the operations of Cincinnati and Taylor and
the remaining increase was due to increased salary, benefits and related costs
attributable to increased sales support personnel.
    
 
   
    RESEARCH AND DEVELOPMENT.  Research and development expenses consist
primarily of personnel costs, engineering supplies, development equipment,
depreciation and overhead costs. Research and development expenses increased
89.6% to $2.6 million for the nine months ended December 31, 1996 from $1.4
million in the comparable prior period. The increase resulted primarily from
increased salary, related benefits and employee procurement expenses due to
increases in personnel headcount, including approximately $600,000 of product
development costs related to Cincinnati and Taylor.
    
 
   
    GENERAL AND ADMINISTRATIVE.  General and administrative expenses consist
primarily of personnel costs related to finance, information systems, and
general management functions, as well as professional fees related to legal,
audit and tax services. General and administrative expenses increased 192.0% to
$2.9 million for the nine months ended December 31, 1996 from $1.0 million for
the comparable prior period. Approximately $1.3 million of the increase related
primarily to additional personnel and facility costs and goodwill amortization
resulting from the operations of Cincinnati and the three month's operating
results of Taylor, with the remaining increase resulting from higher personnel
and associated overhead costs necessary to support the growth of the Company.
    
 
    CHARGE FOR PURCHASED RESEARCH AND DEVELOPMENT.  Purchased research and
development and other acquisition expenses relating to the acquisition of Taylor
totaled approximately $4.9 million and were charged to expense at the
acquisition date in September 1996. Of this expense, $4.7 million represents the
estimated fair value of Taylor's incomplete research and development projects as
determined by independent appraisal.
 
   
    INTEREST EXPENSE AND OTHER, NET.  Interest expense and other, net increased
to $387,000 for the nine months ended December 31, 1996 from $59,500 in the
comparable prior period. The increase primarily related to an increase in
average debt outstanding used to fund the acquisition of Cincinnati and
increased working capital needs.
    
 
   
    PROVISION FOR (BENEFIT FROM) INCOME TAXES.  Provision for income taxes
increased to $599,000 for the nine months ended December 31, 1996 from $494,000
in the comparable prior period. The effective tax rate for the period ended
December 31, 1996 was 44.4%, after giving effect to the impact on taxable income
of the charge for purchased research and development of approximately $4.7
million, as compared to the effective tax rate of approximately 40.0% in the
comparable prior period. This increase was primarily due to non-deductible
goodwill amortization.
    
 
   
    MINORITY INTEREST IN LOSS OF SUBSIDIARY.  A minority interest representing
Digital Electronic's 39.0% share of the net income or loss of Taylor is recorded
on the Company's statements of operations. The Company's ownership of Taylor
Class A Shares may increase by up to 4.0% based on the amount of contingent
consideration paid by the Company in connection with the acquisition. To the
extent the equity interest of the Company in Taylor increases, the percentage
applied to calculate minority interest will be reduced by a corresponding
amount. The minority interest benefit of $1.9 million recorded for the nine
months ended December 31, 1996 represents the minority interest share of the
loss recorded by Taylor, primarily incurred as a result of the charge for
purchased research and development of $4.7 million recorded at the acquisition
date in September 1996.

    ACCRETION TO REDEMPTION VALUE OF COMMON STOCK.  The Company has issued
redeemable Common Stock and Taylor has issued redeemable Taylor Exchangeable
Shares. The redemption rights will automatically terminate upon the closing of
this offering. The Company recorded these redeemable shares at their estimated
redemption values at the date of issuance and subsequent changes in such
redemption value in each reporting period are being accreted. The accretion to
redemption value of Common Stock increased to $9.1 million for the nine months
ended December 31, 1996 from $1.4 million in the comparable prior period.
Approximately $8.9 million of the accretion recorded for the nine months ended
December 31, 1996 was attributable to an increase in the estimated fair value of
the Common Stock from $2.33 per share to $9.00 per share. The remaining
accretion was due to the increase in redemption value using the effective
interest method for the 767,112 redeemable Taylor Exchangeable Shares issued in
connection with the Taylor Transaction. The accretion recorded for the prior
period ended December 31, 1995 is based on the accretion on a straight line
basis of the increase in the estimated fair market value of the Common Stock
from $1.00 per share to $2.33 per share.
    
 
FISCAL YEARS ENDED MARCH 31, 1996 AND MARCH 31, 1995
 
    NET SALES.  Net sales increased 50.9% to $25.7 million for fiscal 1996
compared to $17.1 million for fiscal 1995. This increase resulted primarily from
the growth in sales of the Company's graphics-based operator interface products
and the increase in net sales from products acquired as a result of the
Cincinnati Transaction in January 1996.
 
    GROSS PROFIT.  Gross profit increased 40.7% to $10.4 million for fiscal 1996
from $7.4 million for fiscal 1995. Gross margin decreased to 40.3% for fiscal
1996 compared to 43.2% for fiscal 1995. This decrease in gross margin was
attributable primarily to growth in sales of the QuickPanel product line and an
increase in material cost as a percentage of net sales for such product line due
to unfavorable Yen variances, partially offset by benefits gained through direct
labor and fixed manufacturing leverage.
 
   
    SALES AND MARKETING.  Sales and marketing expenses increased 43.1% to $5.0
million for fiscal 1996 from $3.5 million for fiscal 1995. Of the increase,
approximately $900,000 resulted from increased salary, benefits and commissions
related to increased personnel and higher sales volume, with the balance related
to increased advertising and distributor promotional programs.
    
 
   
    RESEARCH AND DEVELOPMENT.  Research and development expenses increased 28.7%
to $2.0 million for fiscal 1996 from $1.5 million for fiscal 1995. The increase
related primarily to additional costs associated with an increase in engineering
personnel and contract engineering costs, as well as additional personnel costs
related to two month operating results of Cincinnati of approximately $100,000.
    
 
   
    GENERAL AND ADMINISTRATIVE.  General and administrative expenses increased
29.4% to $1.6 million for fiscal 1996 from $1.2 million for fiscal 1995. The
increase related to additional costs associated with the two month operating
results of Cincinnati, including goodwill amortization, along with additional
personnel and associated overhead costs necessary to support the overall growth
of the Company.
    
 
    INTEREST EXPENSE AND OTHER, NET.  Interest expense and other, net increased
3.0% to $169,000 for fiscal 1996 from $164,000 for fiscal 1995. The increase
relates to an increase in the amount outstanding under the Company's line of
credit and a term loan payable to its bank primarily used to finance both the
acquisition of Cincinnati and increases in working capital needs. Other, net for
fiscal 1995 includes costs related to terminated acquisition activities.
 
    PROVISION FOR (BENEFIT FROM) INCOME TAXES.  Provision for income taxes
increased to $665,000 for fiscal 1996 from $247,000 for fiscal 1995. The
effective tax rate for fiscal 1996 was 40.0% compared to 25.5% for fiscal 1995.
The increase in the effective tax rate was primarily due to the recognition of
research and development credits which were fully utilized in fiscal 1995.
 
                                       22
<PAGE>
    ACCRETION TO REDEMPTION VALUE OF COMMON STOCK.  The accretion to redemption
value of common stock increased to $1.6 million for fiscal 1996 from $208,000
for fiscal 1995. This increase was attributable to an increase in the estimated
fair value of the Common Stock from $1.00 per share to $2.33 per share.
 
FISCAL YEARS ENDED MARCH 31, 1995 AND MARCH 31, 1994
 
   
    NET SALES.  Net sales increased 45.6% to $17.1 million for fiscal 1995
compared to $11.7 million for fiscal 1994. This increase resulted principally
from growth in sales of the Company's QuickPanel product line and other
graphics-based operator interface products.
    
 
    GROSS PROFIT.  Gross profit increased 36.1% to $7.4 million for fiscal 1995
from $5.4 million for fiscal 1994. Gross margin decreased to 43.2% for fiscal
1995 compared to 46.2% for fiscal 1994. This decrease was attributable primarily
due to growth in the sales of the QuickPanel product line, which contributed a
lower gross margin than the product mix in the prior period, partially offset by
decreases in material costs and direct labor and fixed manufacturing leverage.
 
   
    SALES AND MARKETING.  Sales and marketing expenses increased 20.1% to $3.5
million for fiscal 1995 from $2.9 million for fiscal 1994. Of the increase,
approximately $400,000 resulted from increased sales commissions related to
higher sales volume, with the remaining increase resulting from advertising and
distributor promotional programs.
    
 
   
    RESEARCH AND DEVELOPMENT.  Research and development expenses increased 27.6%
to $1.5 million for fiscal 1995 from $1.2 million for fiscal 1994. The increase
related to increases in engineering personnel and the associated salaries and
benefits.
    
 
   
    GENERAL AND ADMINISTRATIVE.  General and administrative expenses increased
6.1% to $1.24 million for fiscal 1995 from $1.17 million for fiscal 1994. The
increase related primarily to additional personnel costs and professional fees.
    
 
    CHANGE IN ESTIMATED USEFUL LIFE OF SOFTWARE DEVELOPMENT COSTS.  As a result
of a change in the Company's estimate of the useful life of its capitalized
software development costs, as well as management's belief that the amount of
costs incurred from the time technological feasibility is established for the
Company's internally developed software and the time to market are not material,
a non-recurring charge of $466,000 was incurred in fiscal 1994 to write-off the
remaining portion of internally developed software costs which had been
capitalized in March 1993.
 
   
    INTEREST EXPENSE AND OTHER, NET.  Interest expense and other, net increased
69.8% to $163,000 for fiscal 1995 from $96,000 for fiscal 1994. The increase
relates primarily to costs related to terminated acquisition activities
partially offset by a decrease in the amount outstanding on the Company's line
of credit.
    
 
   
    PROVISION FOR (BENEFIT FROM) INCOME TAXES.  Provision for (benefit from)
income taxes was $247,000 for fiscal 1995 and ($155,000) for fiscal 1994. The
effective tax rate for fiscal 1995 was 25.5% compared to (38.6)% for fiscal
1994. This change in the effective tax rate is primarily due to the utilization
of certain research and development tax credits during fiscal 1995.
    
 
   
    ACCRETION TO REDEMPTION VALUE OF COMMON STOCK.  The accretion to redemption
value of Common Stock increase is attributable to an increase in the estimated
fair value of the Common Stock.

    Results of the Company's operations have fluctuated from quarter to quarter
in the past, and may fluctuate significantly in the future. Such fluctuations
may result from a variety of factors, including the timing of new product
introductions by the Company, its competitors or third parties, the loss of any
of its significant distributors, currency fluctuations, disruption in the supply
of components for the Company's products, changes in product mix or capacity
utilization, the timing of orders from major customers, personnel changes,
production delays or inefficiencies, seasonality and other factors affecting
sales and results of operations. A substantial portion of the Company's sales
for each quarter results from orders received in that quarter. Consequently, the
Company is dependent upon obtaining orders for shipment in a particular quarter
to achieve its sales objectives for that quarter. Furthermore, the Company has
often recognized a substantial portion of its sales in the last month of a
quarter, with sales frequently concentrated in the last weeks or days of a
quarter. A substantial portion of the Company's operating expenses are related
to personnel, development of new products, marketing programs and facilities.
The level of spending for such expenses cannot be adjusted quickly, and is
based, in significant part, on the Company's expectations of future revenue. If
actual revenue levels are below management's expectations, the Company's
business, financial condition and results of operations may be materially
adversely affected. The Company believes that period-to-period comparisons of
its results of operations are not necessarily meaningful and should not be
relied upon as indicators of future performance.
 
LIQUIDITY AND CAPITAL RESOURCES
 
    Prior to the acquisition of a majority interest in Taylor, the Company had
historically funded its operations, including its acquisition of Cincinnati,
primarily through cash flow from operations, private placements of securities
and proceeds from borrowings under its bank line of credit.
 
    In order to finance the Taylor Transaction, the Company entered into a $2.0
million subordinated shareholder note payable, which is due on the earlier of
September 20, 1999 or 10 days after the completion of an initial public
offering. The note bears interest at 20.0%, of which 13.0% is payable in cash on
a monthly basis after December 1996 and 7.0% is payable in Common Stock valued
at $5.00 per share, with a minimum of 27,999 shares issuable even if the note is
repaid within the first year. Additionally, the Company entered into a $2.2
million note with the former principal shareholder of Taylor. The note bears
interest at 12.5% per annum until March 19, 1997, and at 15.0% per annum
thereafter, payable on a monthly basis. The note is required to be paid in full
following the closing of a registered initial public offering of any class of
stock of the Company or upon the sale of Taylor's labor scheduling software
product line currently held for sale by the Company. Finally, the Company
entered into a loan agreement with Digital Electronics, whereby Digital
Electronics loaned the Company $5.0 million. In September 1996, $4.0 million of
such loan was converted into 39.0% of the outstanding Taylor Class A Shares. The
remaining $1.0 million of the Digital Electronics indebtedness is represented by
an unsecured promissory note, accruing interest at a rate of 5.0% per annum and
is due upon the earlier of the completion of an initial public offering or
August 31, 1997. See "Recent Acquisitions -- Taylor Transaction" and "Certain
Transactions."
 
   
    Beginning in fiscal 1998, the Company may become obligated under the terms
of the Taylor Transaction and the Cincinnati Transaction to make payments of
contingent consideration which could be substantial in amount. The Taylor
Transaction requires contingent payments based on Taylor's revenue for the
twelve month periods ending September 30, 1997 and 1998, of up to $4.0 million
for each of these twelve month periods. The Cincinnati Transaction requires
contingent payments based on calendar year 1997 revenues of Cincinnati-related
product sales in excess of historic sales volumes equal to 10.0% of the first
$1.0 million of such excess and 4.0% of any further excess. Additionally, the
Cincinnati Transaction requires a contingent payment equal to 1.25% of the
Company's net sales in excess of $32.0 million for each of the calendar years
1998, 1999 and 2000. Of such contingent payments with respect to the Cincinnati
Transaction, approximately half are payable in shares of the Company's Common
Stock valued at the then fair market value, with the remainder payable in cash.
The Company
    
 
                                       25
<PAGE>
   
has a buy-out right with respect to the contingent payments for the Cincinnati
Transaction for the years 1998, 1999 and 2000, ranging from $1.0 million to $2.0
million depending on the timing of the exercise of such right. Depending on the
magnitude of the contingent payments and the amount of the proceeds from the
sale of the assets held for sale acquired in connection with the Taylor
Transaction, these contingent payments may require the Company to borrow against
its current credit facilities or may require the Company to seek additional
equity or debt financing, which could materially adversely affect the Company's
business and financial position. See "Recent Acquisitions."
    
 
   
    The Company has bank lines of credit aggregating $10.0 million. The amount
that the Company is entitled to borrow under such lines of credit is based on
80.0% to 85.0% of eligible trade accounts receivable and 50.0% of eligible
inventory, up to $4.5 million, of its respective operations. Based on this
formula, the Company would have had approximately $350,000, $869,000 and
$850,000 of available borrowings under its line of credit at March 31, 1994,
1995 and 1996, respectively. All funds advanced pursuant to the lines of credit
are secured by substantially all of the assets of the Company, and such lines of
credit expire on July 1998. The interest rate on borrowings under the lines of
credit is the bank's prime lending rate or LIBOR plus 2.0%, at the option of the
Company or, in the case of $1.0 million of the line of credit, the bank's prime
lending rate. See Note 4 to Consolidated Financial Statements.
    
 
   
    The Company is substantially dependent upon its relationship with Digital
Electronics, the sole supplier of the flat panel displays that are the principal
hardware component incorporated in the graphics-based operator interface
products that represent the Company's best selling product line. For fiscal 1996
and the nine months ended December 31, 1996, sales from this product line
accounted for 70.7% and 62.1%, respectively, of the Company's net sales. The
Company has no contractual arrangement obligating Digital Electronics to
continue to supply these components to the Company or setting prices for the
purchase of the components. The inability of the Company to obtain this hardware
platform from Digital Electronics would have a material adverse effect upon the
operating results and liquidity of the Company.
    
 
   
    Cash (used in) provided by operating activities was $(140,000) in fiscal
1994, $75,000 in fiscal 1995, $(411,000) in fiscal 1996 and $(977,000) for the
nine months ended December 31, 1996. In fiscal 1994, 1995 and 1996 and the nine
months ended December 31, 1996, the Company experienced increases in receivables
and inventory as a result of increases in the Company's sales volume, which was
partially offset by increases in accounts payable and accrued expenses in fiscal
1994, 1995 and the nine months ended December 31, 1996.
    
 
   
    Net cash used in investing activities totaled $207,000, $295,000, $1.9
million and $6.1 million for fiscal 1994, 1995, 1996 and the nine months ended
December 31, 1996, respectively. These activities consisted primarily of
purchases of personal property and equipment and other assets. In addition, for
fiscal 1996 and the nine months ended December 31, 1996, cash used for investing
activities related to the Cincinnati Transaction and Taylor Transaction,
respectively.
    
 
    Management believes the proceeds from this offering, together with cash flow
from operations and borrowings available under the existing bank credit
facilities or replacement facilities will be sufficient to finance the Company's
operations for at least the next 12 months. In the event the Company acquires
one or more businesses or products, the Company's capital requirements could
increase substantially, and there can be no assurance that additional capital
will be available on terms acceptable to the Company, if at all.
 
   
NEW ACCOUNTING PRONOUNCEMENTS
    
 
   
    In March 1995, the Financial Accounting Standards Board (the "FASB") issued
Statement No. 121, "Accounting for the Impairment of Long-Lived Assets and for
Long-Lived Assets to be Disposed Of." This statement requires long-lived assets
and certain intangible assets to be carried at the lower of cost or fair value
less cost to sell if recoverability is determined to be questionable. The
Company adopted this
    
 
                                       26
<PAGE>
   
statement effective April 1, 1996, and such adoption did not have a material
impact on the Company's results of operations.
    
 
   
    In November 1995, the FASB issued Statement No. 123, "Accounting for
Stock-Based Compensation." This statement is effective for fiscal years
beginning after December 15, 1995. Companies have a choice to include a
reasonable estimate of expense for all stock-based compensation in the statement
of operations, or to disclose the effect of adopting the provisions of the
statement on a pro forma basis in a footnote to the financial statements. The
Company adopted this statement during the nine months ended December 31, 1996.
See Note 8 of Notes to Consolidated Financial Statements.

    Total Control designs, develops and markets products and technology for the
control segment of the industrial automation market. The Company's broad range
of products are used to define, monitor and maintain the operation, sequencing
and safety of industrial equipment and machinery on the factory floor. These
products range from closed architecture programmable logic controller operator
interfaces to open architecture control software and systems, and are sold
primarily through an international network of independent distributors with over
200 sales locations. End-users of the Company's products include Abbott
Laboratories, The Boeing Company, The Coca-Cola Company, The Dow Chemical
Company, Eastman Kodak Company, Ford Motor Company, General Motors Corporation,
Nabisco, Inc. and USX Corporation.
    
 
THE INDUSTRIAL AUTOMATION INDUSTRY
 
    Industrial manufacturing processes have become increasingly complex and
difficult to manage, especially at the factory floor level. While trying to
respond to such complexities, manufacturers are simultaneously under increased
competitive pressures to lower costs, increase quality and efficiency and meet
customer delivery deadlines. These pressures are often further complicated by
the additional burden of compliance with governmental regulations, safety
procedures and internal information reporting needs. To manage the complexity of
the manufacturing environment and to satisfy these requirements, manufacturers
must collect and analyze large amounts of data concerning their operations on a
timely, comprehensive and efficient basis. Industrial automation provides
solutions to these challenges.
 
    The industrial automation industry can be divided into three segments:
planning, execution and control. Products in the PLANNING segment translate
information, such as customer orders and material purchases, into a
comprehensive plan for the manufacture of products. Products in the EXECUTION
segment schedule and monitor plant resources to ensure that machines produce
products in accordance with the production plan. Products in the CONTROL
segment, upon which the Company primarily focuses, allow users to define,
monitor and maintain the operation, sequencing and safety of industrial
equipment and machinery on the factory floor.
 
   
    Specifically, control segment functions include supervisory controls, which
allow individual machines to interact with each other; operator interfaces,
which allow a human operator to communicate with an individual machine; and
controllers, including programmable logic controllers ("PLCs") and industrial
computers, which intelligently control the operation of a machine. Harbor
Research, Inc., a technology industry market research firm, projects that annual
sales of control segment products in those categories in which the Company
currently offers products will grow from $8.6 billion in 1995 to over $12.8
billion in 2000. This market is presently dominated by proprietary control
products from manufacturers of PLCs such as Allen-Bradley, Siemens Energy and
Automation, Inc. and GE Fanuc Automation North America, Inc.
    
 
   
    Proprietary control products have many inherent limitations, including
fixed, vendor-defined functionality and difficulty in programming, integrating
and networking with other proprietary products and systems. As manufacturers
benefited from the increasing automation of individual machines, difficulties
remained in integrating proprietary control segment products into different
parts of the manufacturing process. With little communication ability among
these products, multiple "islands of information" within a manufacturing
operation resulted as products from one vendor could not easily share
information with products from another vendor, forcing a manufacturer to depend
upon a single vendor. For the manufacturer, this resulted in a high cost of
ownership and the inability to take advantage of the inherent cost and
performance benefits associated with standards-based products.
    
 
                                       28
<PAGE>
    In response to these problems, the Company believes end-users in the control
segment of the industrial automation marketplace are beginning to migrate
towards open systems-based products. This migration is occurring gradually as
manufacturers build new facilities and replace or upgrade existing facilities.
By moving to interoperable products, manufacturers can benefit from standard
networking protocols which provide enhanced connectivity, intuitive graphical
user interfaces, enhanced application software functionality and the continued
cost reductions associated with general purpose hardware. The availability of a
standardized, easy-to-support operating system, such as Windows NT, allows
industrial automation products to be based upon an open architecture platform
with widespread market acceptance. In addition, the Company believes the advent
of relatively low cost network computers, linked together through Internet or
intranet protocols and technologies, will allow manufacturers and end-users
greater communication and functionality in automation systems. Eventually, the
Company believes these trends may result in the development of network computer
systems which combine PLC and operator interface functionality to control the
actions of machines on the factory floor.
 
    Distributors are an integral part of the technological evolution occurring
in the industrial automation marketplace. Traditionally, a substantial portion
of industrial automation products have been sold through the use of independent
distributors because they provide vendors with broad geographic and account
coverage. Distributors also provide customers with a broad product line and
local support and service and generally have well established, long-standing
relationships with customers. As competitive pressures force distributors to
limit the number of vendors and product lines they represent, the Company
believes distributors will seek to represent vendors who offer a comprehensive
line of products that will fill the needs of customers who have not migrated
towards open systems as well as those who demand a line of products based on
interoperable software and hardware. Because distributors base their business on
satisfying the demands of their customer base, they need to offer a migration
path from traditional industrial automation technology to products based on open
systems technology.
 
    The technology shift in the market for control products is similar to the
transition in the office environment towards open client/server computing. The
Company believes that an opportunity exists for vendors that can offer, through
distribution, control segment products which span the range from proprietary,
closed architecture products to standards-based open-system products.
 
THE TOTAL CONTROL ADVANTAGE
 
    Total Control believes that it offers to its distributors one of the most
complete and versatile lines of control segment products available, ranging from
lower-end operator interface products to sophisticated open architecture control
software and systems. The Company's graphics-based operator interfaces have the
ability to communicate with most major proprietary systems on the factory floor,
as well as to communicate among each of these major proprietary systems.
 
    As manufacturers begin to introduce sophisticated, networked information
management systems, the ability to communicate with each machine on the factory
floor becomes critical, making the Company's products a natural bridge between
old and new technology. The availability and cost advantage of open systems
technology is accelerating the introduction of new products on the factory
floor, and in turn accelerating the requirement for distributors to carry a line
of products that spans the functionality spectrum. The Company believes that its
broad line of control segment products, its international network of independent
distributors and its substantial base of end-users position it to become a
leading worldwide provider of products and technology in the control segment of
the industrial automation market.

STRATEGY
 
    The Company's goal is to become a leading worldwide provider of products and
technology in the control segment of the industrial automation market. Key
elements of the Company's strategy are as follows:
 
   
    LEVERAGE THE SUCCESS OF QUICKPANEL.  The Company's principal product line,
QuickPanel and other similar products, has gained a leadership position in its
market. It has been the Company's most successful product line, accounted for
70.7% and 62.1% of net sales in fiscal 1996 and the nine months ended December
31, 1996, respectively. The Company believes that this product line delivers
price/ performance leadership and has allowed the Company to gain visibility and
enhance its reputation both with distributors and with end-users. The Company is
beginning to invest substantial resources in developing future generations of
the QuickPanel product line aimed at giving it the functionality of a
standards-based interoperable network computer and allowing the Company to
extend the functionality of the product into the open systems environment.
    
 
   
    DEVELOP PRODUCTS FOR SALE THROUGH INDEPENDENT DISTRIBUTORS.  The Company
utilizes an international network of independent distributors with over 200
sales locations that specialize in sales of industrial automation products. The
Company believes that, because distributors are seeking to make their operations
more efficient by reducing the number of approved vendors from which they buy
products, they have come to expect that the Company will provide a broad range
of products which serve the control segment of the market. The Company is
focused on developing industrial automation products that, from price,
performance and support perspectives, satisfy the selling requirements of its
distributors, and the Company does not currently anticipate designing or
marketing products that are not suitable for its existing independent
distributors. As the industrial automation industry moves from proprietary
systems to open architecture technology, the Company anticipates that a wide
variety of new and existing hardware and software technologies will converge,
providing a broader range of sales opportunities for both the Company and its
distributors.
    
 
   
    EXPAND THE NETWORK OF INDEPENDENT DISTRIBUTORS.  Since the Company's
decision in 1994 to channel its sales efforts through distributors, the Company
has increased the number of distributor sales locations from approximately 130
in October 1994 to approximately 200 in December 1996. The Company seeks to
establish and maintain relationships with the leading industrial automation
product distributors in each of the geographic market areas in which it competes
and periodically evaluates its distributors' market positions. The Company
believes that by offering a comprehensive migration path from closed to open
architecture products in the industrial automation industry, its mindshare among
distributors will continue to be enhanced, making it an attractive choice for
distributors.
    
 
    LEVERAGE THE TREND TOWARDS OPEN SYSTEMS.  The Company believes it is
positioned to gain a leadership position in the next generation of industrial
automation technologies. Because the Company is migrating its products to
object-oriented software products that run in the Microsoft operating
environment, the Company believes it will be in a position to benefit from the
expected rapid acceptance of Microsoft Windows NT on the factory floor. The
Company's goal is to provide cost effective distributed client/server products
that can improve factory productivity and enhance business management and
control.
 
    SEEK PRODUCT PORTFOLIO EXPANSION OPPORTUNITIES.  The industrial automation
industry continues to be highly competitive and fragmented. The Company believes
that this fragmentation will allow it to continue to acquire companies, assets
and product lines in this market, although the Company does not currently have
any planned acquisitions. This strategy will allow the Company to continue to
expand its product portfolio and leverage its distribution channel in order to
continue to build market share. The Company's acquisition strategy has been and
will continue to be to seek companies, assets and products
 
                                       30
<PAGE>
that are attractive to the Company's current end-user base, require
technological understanding similar to the Company's current products, and can
be easily marketed through its independent distributors.
 
    FOCUS RESOURCES ON STRATEGIC AREAS.  The Company's strategy is to maximize
flexibility and efficiency in the development of its products in order to
quickly and inexpensively bring them to market. The Company seeks to use the
most efficient methods available to implement this strategy, including building
strategic alliances, such as the Company's relationship with Digital
Electronics. The Company intends to continue to limit spending in non-strategic
areas by using third party suppliers for most of its hardware and manufacturing
needs, thereby eliminating the need to build and maintain costly manufacturing
infrastructures.
 
PRODUCTS
 
    The Company's products are used to define, monitor and maintain the
operation, sequencing and safety of industrial equipment and machinery on the
factory floor. The Company offers a wide range of products, from proprietary PLC
operator interfaces to open architecture control software and systems. The
Company designs these products to satisfy the price and performance
characteristics demanded by its distributors and end-users, and sells products
to its distributors at a discount from the end-user list price for such
products. The table below summarizes the Company's principal product offerings
and the typical list price range for the products:

    GRAPHICS-BASED OPERATOR INTERFACE PRODUCTS.  These products are easy-to-use
displays which allow human machine operators to monitor and program industrial
equipment by receiving and inputting information through a display screen. The
Company has sold over 30,000 units in this class since 1989, and sales from
these graphics-based product lines represented 70.7% and 62.1% of the Company's
net sales in fiscal 1996 and for the nine months ended December 31, 1996,
respectively.
    
 
    The Company's products in this category consist of monochrome and color
graphical displays on either a flat panel or a cathode ray tube ("CRT") based
screen. These products offer graphical touchscreen operator interfaces that are
cost-effective replacements to a variety of discrete devices, from push buttons
to message centers. The trend in this product class is towards smaller, flat
panel-based displays as opposed to the more bulky CRT screens. The QuickPanel
flat panel product line has eight separate models, while the CRT-based
SmartScreen is sold in a variety of screen sizes and configurations. All of
 
                                       31
<PAGE>
these units are designed for single operator stations and include connectivity
technology to communicate with proprietary PLCs. The Company's graphics-based
operator interface products can communicate with over 20 major PLCs and PLC
networks including Allen-Bradley Remote I/O-TM-, Data Highway PLUS-TM-, Modicon
Modbus Plus-TM-, and GE Genius I/O-TM-. Consequently, these products are capable
of serving as bridges to open systems products and technology.
 
    SOFTWARE TOOLS.  The Company's software tools are described below:
 
        PROCESSWINDOW. ProcessWindow is a graphical operator interface software
    program that enhances the man-machine interface ("MMI") that occurs between
    a human operator and a particu-
    lar piece of factory equipment. The product provides a variety of
    information management and display capabilities that can be programed by the
    user, runs under Windows 3.1 and NT and is capable of communicating with
    many different control systems. In addition, it can be linked to the
    Company's ProWorx and Waltz software products.
 
        PROWORX. ProWorxPlus and ProWorx IV are software tools which support the
    operation of PLCs. These products allow a human operator to easily and
    efficiently program a PLC to control the parameters of a machine's
    operation. Each of the products in this class run on DOS- or Windows-
    compatible PCs, and support PLCs manufactured by Allen-Bradley and Modicon.
 
   
        WALTZ. The Company's Waltz control software is a PC-based control
    product that allows a machine operator to have direct PC control over the
    operation of a machine without the necessity of a PLC. Waltz runs on Windows
    NT and includes an IEC 1131-3 compatible editor, a controller, communication
    drivers to various types of input/output systems, and an operator interface
    based on the Company's ProcessWindow software. By utilizing general purpose
    computers and high-performance, real-time operating systems, such as Windows
    NT, this software tool allows manufacturers to reduce dependency on
    proprietary PLCs and shift their operations to open systems technology.
    
 
        SECURWORX. Users of multiple PLCs and other programmable devices may be
    faced with hundreds of controllers on a particular site, each containing
    unique application programs, connected by means of a local area network. As
    human operators make changes to the programming of a particular PLC, the
    Company's SecurWorx client/server database management software provides
    version control management as well as password protection. SecurWorx
    produces an audit trail of the controller program changes and is integrated
    with the Company's ProWorx software.
 
        QUICKDESIGNER. QuickDesigner is a Windows compatible software design
    tool used with the Company's flat panel operator interface products. This
    software tool allows users to configure the display features on the
    graphical flat panel touchscreen to meet their individual needs.
 
    TEXT-BASED OPERATOR INTERFACES.  These products, such as Grey-Line,
MessageCenter and QuickMarquee, report on the operation of industrial equipment
by sending textual messages to the machine operator through the use of a digital
display apparatus, with display sizes ranging from one quarter inch to eight
inches. This allows the machine operator to review messages as needed, rather
than having to constantly monitor a complicated control panel filled with push
buttons, pilot lights and selector switches. These products, although the most
basic types of operator interfaces, are still widely popular and allow the
Company to provide a broad range of products for the control segment of the
industrial automation market.
 
    INDUSTRIAL COMPUTER WORKSTATIONS.  The Company offers the TCS family of
ruggedized, open architecture computers, workstations and stand alone computers
and monitors specifically designed for the harsh requirements of the factory
floor. The products vary based on size, mounting configurations, display types,
memory, storage devices, key pads and touchscreen options. In addition, the TCS
family of industrial computers is also available bundled with the Company's
software products.
 
                                       32
<PAGE>
   
    PRODUCTS UNDER DEVELOPMENT.  The Company intends to focus its product
development efforts on incorporating the high-end functionality of the Company's
software tools into its existing text-based and graphics-based operator
interface products. This development would allow the graphics-based products to
offer the same control and networking functionality that is currently available
in the software tools. The Company believes the resulting products would provide
enhanced price/performance leadership, allowing open architecture to be
available at the lower end of the product spectrum and providing the end-user
the benefit of enhanced flexibility, connectivity and functionality without
having to convert its control systems to PC-based systems. In particular, the
Company is beginning to invest substantial resources in developing future
generations of the QuickPanel product line aimed at giving it the functionality
of an open standards, interoperable network computer.
    
 
    SERVICE AND SUPPORT.  The Company maintains an inventory of spare parts and
service stock. The shipment of spare parts and the performance of repair service
on out-of-warranty products is a small, but high margin part of the Company's
business. For its software products, the Company offers annual customer support
contracts that entitle the purchaser to free phone support and software upgrades
during the length of the contract.
 
END-USERS
 
   
    The Company has an installed base of over 33,000 operator
interface/industrial computer products, and an installed base for its software
tools consisting of over 7,000 licensees, which have over 33,000 authorized
licensed seats. The following list provides a selection of the Company's
end-user base.

SALES, MARKETING AND SUPPORT
 
   
    The Company's products are sold in more than 25 countries, primarily through
an international network of independent distributors having approximately 200
sales locations. The Company seeks to establish and maintain relationships with
the leading industrial automation distributors in each of the geographic market
areas in which it competes, and periodically evaluates its distributors' market
positions. The Company's distributors typically provide customer training,
application engineering and support. The Company believes that its commitment to
service and support has been and will continue to be a significant factor in its
success. Sales to one distributor, McNaughton-McKay Electric Company, accounted
for 13.9%, 9.5% and 8.7% of the Company's net sales in fiscal 1995 and 1996 and
the nine months ended December 31, 1996. As of December 31, 1996, the Company's
sales, marketing and technical support organization consisted of 75 employees
and 45 independent sales representatives. This organization is managed by
regional sales managers located in Atlanta, Georgia; Cincinnati, Ohio; San
Francisco, California; Pittsburgh, Pennsylvania; Melrose Park, Illinois;
Edmonton, Alberta; Sao Paulo, Brazil; and Birmingham, England. This organization
supports the Company's independent distributors and complements their selling
efforts by targeting large end-users, system integrators, original equipment
manufacturers and others.
    
 
   
    In addition to its network of independent distributors, the Company
maintains a 40.0%-owned joint venture investment in Pro-face, HMI B.V.
("ProFace"), a distributor located in the Netherlands. ProFace is the European
distributor of both the Company's and Digital Electronics' products.
    
 
PRODUCT DEVELOPMENT
 
    The Company maintains an active product development program, including a
joint development arrangement with Digital Electronics for certain projects. The
Company's strategy is to develop new product offerings and existing product
extensions which are responsive to customer demands and satisfy the needs of the
Company's distributors. A significant portion of the Company's product
development expenses are targeted to developing products that will provide
additional functionality requested by the Company's end-users.
 
   
    As of December 31, 1996, the Company had a product development staff of 80
full-time employees, including software, electronic and mechanical design
engineers, product managers, application engineers and directly associated staff
members involved in technical documentation and product support. During fiscal
1994, 1995 and 1996 and the nine months ended December 31, 1996, research and
development expenses were 10.1%, 8.9%, 7.6% and 9.0% of net sales, respectively.
The Company anticipates that it will continue to commit substantial resources to
product development efforts in the future.
    
 
SUPPLY RELATIONSHIP WITH DIGITAL ELECTRONICS
 
   
    Digital Electronics is the Company's sole supplier of the flat panel screens
that are the principal hardware component incorporated in its graphics-based
operator interface products, the Company's best selling product class. During
fiscal 1994, 1995 and 1996 and for the nine months ended December 31, 1996,
sales from this product class accounted for 45.9%, 61.9%, 70.7% and 62.1%,
respectively, of the Company's net sales. Digital Electronics is not under a
contractual obligation to continue to supply the flat panel screens and there is
no formal agreement between the Company and Digital Electronics with respect to
pricing. A disruption in the supply of products from Digital Electronics or a
significant price increase could have a material adverse impact on the Company's
business, financial condition and results of operations until an alternative
source of supply could be established. The Company has the exclusive right to
market and distribute in North and South America all hardware products
manufactured by Digital Electronics pursuant to the terms of a distribution
agreement, which expires in April 2005. See "Risk Factors -- Dependence Upon
Digital Electronics Corporation" and "Certain Transactions."
    
 
                                       34
<PAGE>
MANUFACTURING AND SUPPLY
 
   
    The Company performs final assembly and testing for substantially all of its
products at its Melrose Park and Edmonton facilities, which are certified under
ISO-9001, an international quality standard. The assembly process encompasses
the assembly of sheet metal parts, keyboards, displays and electronic circuit
boards into finished goods and the duplication of software products on disks or
other electronic media. The Company subcontracts the assembly of circuit boards
and the fabrication of sheet metal and front panel bezels. The Company uses a
number of firms for these subcontracted services and is not materially dependent
upon any third party that performs these services.
    
 
    Except for the flat panel displays purchased from Digital Electronics,
substantially all of the components used in the Company's products are available
from multiple sources and the Company maintains more than one source of supply
for all material components. However, the Company may experience supply
shortages due to various factors, including increases in market demand for
certain components and the limited capacity of certain suppliers. Although the
Company believes that the partial or complete loss of one or more of its
suppliers, other than Digital Electronics, is not likely to have a material
long-term impact on its operations, such a loss could in the short term result
in significant production delays, require the Company to seek alternative
sources of supply and increase its cost of goods sold and, therefore, could have
a material adverse effect on the Company's business, financial condition and
results of operations.
 
COMPETITION
 
   
    Competition in the industrial automation industry is intense and
characterized by rapidly advancing technologies. The Company faces substantial
competition in all of its product lines and competition may increase if new
competitors enter the market or if existing competitors expand their product
offerings. Competitors include large PLC manufacturers, including Allen-Bradley
(a subsidiary of Rockwell International, Inc.), Eaton Corp., GE Fanuc Automation
North America, Inc. (a joint venture between General Electric Corporation and
Fanuc Limited), Groupe Schneider S.A. (consisting of Modicon, Inc., Schneider
S.A., Square D Co. and Telemechanique, Inc.) and Siemens Energy and Automation,
Inc. (the U.S. subsidiary of Siemens A.G.). Competitors also include software
developers, such as IDT, Inc. (a subsidiary of Eaton Corp.), Intellution Inc. (a
subsidiary of Emerson Electric Corporation), Nematron, Inc. and Wonderware, Inc.
Many of these competitors are larger and have significantly greater resources
than the Company. These competitors, as well as potential future competitors,
may have greater name recognition and a larger installed base than the Company.
The Company believes that over time this competition may have the effect of
reducing average selling prices of comparable products, and thus, in order to
maintain sales, the Company may be forced to increase unit volumes or increase
the performance of its products in order to offset or reduce any decreases in
selling prices. In the event such price reductions become necessary, the
Company's ability to maintain gross margins will depend on its ability to reduce
cost of goods sold in an amount sufficient to compensate for any decreases in
selling prices. The Company's competitors could in the future introduce products
with more features and lower prices than the Company's product offerings, bundle
existing or new products with other products or systems to compete with the
Company or exert leverage or other competitive pressures on distributors to give
priority to their own products at the expense of the Company's products. As the
market for industrial automation and process control solutions develops, a
number of companies with significantly greater resources than the Company may
attempt to increase their presence in the market by acquiring and/or forming
strategic alliances with competitors of the Company. The Company competes on the
basis of the reliability, price and ease of use of its products, the quality and
breadth of its distributor network and its customer service. The Company
believes that it competes favorably with respect to these factors.
    
 
INTELLECTUAL PROPERTY
 
    The Company's success depends in part on its ability to maintain the
proprietary and confidential aspects of its products as they are released. The
Company does not own any significant patents, and relies on a combination of
copyrights, employee non-disclosure agreements and other means to establish and
 
                                       35
<PAGE>
protect its proprietary rights. There can be no assurance that the precautions
taken by the Company adequately protect the Company's technology. In addition,
many of the Company's competitors have obtained or developed, and may be
expected to obtain or develop in the future, patents, copyrights or other
proprietary rights that cover or affect products that perform functions similar
to the products offered by the Company. The inability of the Company for any
reason to protect existing technology or otherwise acquire necessary technology
could prevent distribution or licensing of the Company's products, which would
have a material adverse effect on the business, financial condition and results
of operations of the Company. The Company licenses its software products
primarily under "shrink wrap" license agreements that are not signed by
licensees and, therefore, may be unenforceable under the laws of certain foreign
jurisdictions. In addition, in some instances the Company licenses its software
products under agreements that give licensees limited access to the source code
of the Company's products. Accordingly, despite precautions taken by the
Company, it may be possible for unauthorized third parties to copy certain
portions of the Company's products or to obtain and use information that the
Company regards as proprietary.
 
    Certain technology used in the Company's products is licensed from third
parties. These licenses generally require the Company to pay royalties and to
fulfill confidentiality obligations. In the future, it may be necessary or
desirable for the Company to seek additional licenses of intellectual property
rights held by third parties. There can be no assurance that such licenses will
be available on favorable terms, if at all.
 
    The Company believes that, due to the rapid pace of innovation within its
industry, factors such as the technological and creative skills of its personnel
are more important to establishing and maintaining a technology leadership
position than are the various legal protection of its technology. The Company
believes that its products and technology do not infringe any existing
proprietary rights of others, although there can be no assurance that third
parties will not assert infringement claims in the future.
 
EMPLOYEES
 
   
    As of December 31, 1996, the Company had a total of 240 full-time employees,
of which 80 were in product development, 75 were in sales and marketing, 54 were
in manufacturing and operations and 31 were in general and administrative
functions. The Company also hires temporary employees as needed. None of the
employees are represented by a labor union or subject to a collective bargaining
agreement. The Company believes that its employee relations are good.
    
 
FACILITIES
 
   
    The Company's headquarters and principal manufacturing facilities are
located in Melrose Park, Illinois, in a 39,000 square foot leased facility, of
which approximately 24,000 square feet is used for manufacturing and storage.
The facility is owned by a partnership which is controlled by officers and major
shareholders of the Company. See "Certain Transactions." This facility is leased
through April 2002. In addition, the Company leases a 22,000 square foot
facility in Edmonton, Alberta. The Company also leases sales offices. As part of
the acquisition of Cincinnati, the Company became the primary obligor of a
29,670 square foot facility in Cincinnati, Ohio. The Company is currently
involved in negotiations for the sublease of this facility through the remainder
of the original lease term, which expires in August 2000. The Company
anticipates that it will be necessary in the near future to lease additional
inventory storage space, and management believes suitable space is available to
meet this need in the Melrose Park vicinity. With the exception of such
additional inventory storage space, the Company believes that its facilities are
adequate for its current needs.
    
 
LEGAL PROCEEDINGS
 
    The Company is not involved in any material legal proceedings.

(1) There was no public trading market for the Common Stock on March 31, 1996.
    Accordingly, solely for purposes of this table, the values in these columns
    have been calculated on the basis of the assumed initial public offering
    price of $9.00 per share (rather than a determination of the fair market
    value of Common Stock on March 31, 1996), less the applicable option
    exercise price.
 
STOCK COMPENSATION PLANS
 
   
    1996 STOCK OPTION PLAN.  The Company has adopted the 1996 Stock Option Plan
(the "1996 Plan"), under which the Compensation Committee may grant options to
purchase up to 550,000 shares of Common Stock to management, employees and
advisors of the Company. The 1996 Plan provides for the grant of incentive stock
options ("Incentive Options") within the meaning of Section 422 of the Internal
Revenue Code of 1986, as amended (the "Code"), and non-statutory stock options
that do not qualify as incentive stock options under Section 422 of the Code
("Non-Statutory Options"). To date, no options have been granted under the 1996
Plan. The Board of Directors intends to grant, immediately following the
effectiveness of this offering, options to purchase an aggregate of 300,000
shares of Common Stock at an exercise price equal to the initial public offering
price per share in this offering. Mr. Gihl will receive options to purchase
50,000 shares of Common Stock pursuant to this grant.
    
 
    1996 NON-EMPLOYEE DIRECTORS' STOCK OPTION PLAN.  The Company has adopted the
1996 Non-Employee Directors' Stock Option Plan (the "Directors' Plan"), under
which 120,000 shares of Common Stock have been authorized for issuance. All
non-employee directors will receive an option to purchase 12,000 shares of
Common Stock under the Directors' Plan on the day after each annual meeting of
the shareholders of the Company, provided that he or she then continues to serve
as a member of the Board of Directors. All such grants will be Non-Statutory
Options. The options granted under the Directors' Plan are exercisable beginning
six months from the date of grant. No options have been granted under the
Directors' Plan.
 
   
    1996 DISCOUNT STOCK PURCHASE PLAN.  The Company has established the 1996
Discount Stock Purchase Plan (the "Purchase Plan") and reserved 250,000 shares
of Common Stock for issuance thereunder. Pursuant to the Purchase Plan, eligible
employees of the Company may be given an opportunity to purchase Common Stock of
the Company through payroll deductions during purchase periods of six months or
such shorter periods as may be determined by the Board, with the first offering
period commencing on the first March 31 or September 30 occuring after the
closing of this offering. Eligible employees become participants in the Purchase
Plan by delivering to the Company, prior to the commencement of the purchase
period, an agreement authorizing a payroll deduction of up to 10.0% of such
employee's base compensation during the purchase period. The purchase price per
share at which shares are sold in an offering under the Purchase Plan is the
lesser of (i) 85.0% of the fair market value of a share of Common Stock on the
first day of the purchase period, or (ii) 85.0% of the fair market value of a
    
 
                                       41
<PAGE>
share of Common Stock on the last day of that purchase period. Rights granted
under the Purchase Plan are intended to qualify for favorable federal income tax
treatment associated with rights granted under an employee stock purchase plan
under the provisions of Section 423 of the Code. No shares have been issued
under the Purchase Plan.
 
   
    1993 STOCK OPTION PLAN.  In 1993, the Company adopted the 1993 Stock Option
Plan, under which 375,000 shares of Common Stock have been reserved for issuance
(the "1993 Stock Plan"). There are currently options to purchase 295,974 shares
of Common Stock outstanding under the 1993 Stock Plan at a weighted average
price per share of $2.85, of which 159,194 will be exercisable as of February 9,
1997. The Company's Board of Directors has adopted a resolution that no future
grants of options may be made under the 1993 Stock Plan.
    
 
COMPENSATION COMMITTEE INTERLOCKS AND INSIDER PARTICIPATION
 
    The Board of Directors has not had a Compensation Committee prior to this
offering and the functions of the Compensation Committee have been performed by
the Board of Directors as a whole. Immediately following the closing of the
offering, the Compensation Committee will become effective and will be composed
of Messrs. Hurd and Kramer. For information concerning certain transactions and
relationships among the Company and the members of the Board of Directors, see
"Recent Acquisitions -- Taylor Transaction" and "Certain Transactions."

<PAGE>
                              RECENT ACQUISITIONS
 
TAYLOR TRANSACTION
 
    In September 1996, the Company completed a series of transactions resulting
in its holding 61.0% of the Class A Shares of Taylor. In the first step of this
transaction, the Company acquired all of the voting stock of Taylor in exchange
for aggregate consideration of $7.4 million, the right to receive contingent
consideration as described below and 767,112 Taylor Exchangeable Shares. Of the
$7.4 million, $2.2 million was in the form of a promissory note from Taylor to
Neil R. Taylor, the former majority shareholder of Taylor, and the remainder was
paid in cash at the closing. The 767,112 Taylor Exchangeable Shares are
convertible into 767,112 shares of Common Stock of the Company at any time at
the election of the holders of such shares. Taylor's Articles of Organization
provide that if the Company has not effected an initial public offering of any
class of its capital stock prior to September 19, 1997, the holders of the
Taylor Exchangeable Shares will have the right to sell their shares to Taylor or
the Company for an aggregate amount equal to $6.0 million payable over three
years. See "Description of Capital Stock -- Taylor Exchangeable Shares."
 
    The $2.2 million promissory note issued to Neil R. Taylor accrues interest
on the principal sum outstanding from time to time at a rate of 12.5% per annum
until March 19, 1997, and at a rate of 15.0% per annum thereafter. The Company
has guaranteed repayment of all amounts due under this note. The Company is
required to pay all amounts outstanding under such promissory note following the
closing of a registered initial public offering of any class of stock of the
Company. The note is secured by the assets of Taylor's labor scheduling software
product line. Upon a default under this note by Taylor or the Company, Mr.
Taylor would have the right to retain this product line in full satisfaction of
amounts due under the note. The Company will use a portion of the net proceeds
of this offering (or, if earlier, the sale of the labor scheduling software
product line) to repay this note.
 
    Mr. Taylor and the former shareholders of Taylor also hold certain
registration rights with respect to their shares of Common Stock issuable upon
conversion of their Taylor Exchangeable Shares. See "Description of Capital
Stock -- Registration Rights."
 
    Under the Taylor Transaction, the former shareholders of Taylor are also
entitled to receive certain contingent consideration pursuant to an earn-out
formula. Under such formula, if the actual consolidated revenues of Taylor ("Net
Revenues") between October 1, 1996 and September 30, 1997 exceed $8.0 million,
Taylor will pay the former shareholders an aggregate amount equal to $1.0
million, and to the extent that Net Revenues during such period exceed $9.2
million, Taylor will pay to the former shareholders an aggregate amount, not to
exceed $3.0 million, equal to 50.0% of such excess. In addition, for the period
between October 1, 1997 and September 30, 1998, if Net Revenues exceed $8.0
million, Taylor will pay to the former shareholders an aggregate amount equal to
$1.0 million, and to the extent that Net Revenues during such period exceed
$10.6 million, the Company will pay to the former shareholders an aggregate
amount, not to exceed $3.0 million, equal to 50.0% of such excess. The Company
has guaranteed the payment of all amounts of contingent consideration by Taylor
to the former shareholders of Taylor.
 
    Digital Electronics originally loaned the Company an aggregate of $5.0
million in order to consummate the Taylor Transaction. Immediately thereafter,
$4.0 million of the loan was converted into 3,900 Taylor Class A Shares,
representing 39.0% of the aggregate amount of such shares. The remaining $1.0
million of indebtedness is represented by an unsecured promissory note from the
Company payable to Digital Electronics, accruing interest at a rate of 5.0% per
annum, maturing on the earlier of August 31, 1997 or the completion of an
initial public offering of any class of capital stock of the Company. The
Company will use a portion of the net proceeds of this offering to repay this
note.
 
    Pursuant to an arrangement with Digital Electronics, the Company agreed that
to the extent Taylor is required to make any payment of contingent consideration
to the former shareholders of Taylor, the Company will transfer funds to Taylor
in an amount equal to such contingent consideration. To the extent the Company
funds a portion of a contingent payout, the Company is permitted to cause Taylor
to issue additional Taylor Class A Shares to the Company in order to increase
the Company's ownership interest in the outstanding Taylor Class A Shares by the
following percentage: 2.0% multiplied by a fraction, the
 
                                       43
<PAGE>
numerator of which is the entire contingent consideration payable to the
shareholders and the denominator of which is $4.0 million. If the entire amount
of contingent consideration is paid to the former Taylor shareholders, Digital
Electronics' ownership interest in Taylor will be decreased to 35.0% and the
Company's interest will be increased to 65.0%.
 
    To provide additional financing for the Taylor Transaction, the Company
borrowed $2.0 million from A.B. Siemer, a director and significant shareholder
of the Company, pursuant to a promissory note dated as of September 19, 1996.
The outstanding principal amount under this note is due and payable on the
earlier of September 19, 1999, or ten days after the closing of an initial
public offering of any class of capital stock of the Company. The unpaid
principal balance of this note bears interest at a rate equal to 20.0% per
annum, 13.0% of which is payable in cash and 7.0% of which is payable in shares
of Common Stock of the Company, valued at $5.00 per share, with a minimum of
27,999 shares issuable even if the note is paid in the first year. The cash
portion of accrued and unpaid interest is due and payable monthly after December
31, 1996, while the stock portion of accrued and unpaid interest is due and
payable on the last day of each calendar year beginning on December 31, 1997.
The Company will use a portion of the net proceeds of this offering to repay
this note in full.
 
    The Taylor Transaction was accounted for under the purchase method of
accounting. For a further discussion of the accounting treatment of the Taylor
Transaction and certain accounting charges in connection therewith, see
"Management's Discussion and Analysis of Financial Condition and Results of
Operations -- Overview."
 
CINCINNATI TRANSACTION
 
    In January 1996, a wholly owned subsidiary of the Company merged with
Cincinnati. As consideration for the transaction, the shareholders of Cincinnati
received $499,990 in cash and the right to receive contingent consideration as
described below. In addition, the majority shareholder of Cincinnati received
150,003 shares of the Company's Common Stock. Under the terms of this
transaction, the former majority shareholder of Cincinnati has the right after
January 29, 1998 to require the Company to purchase all, but not less than all,
of the 150,003 shares issued to him for their then fair market value. This
shareholder has agreed to waive this right effective upon the closing of this
offering.
 
   
    As additional contingent consideration, the former shareholders of
Cincinnati are entitled to the payment of certain contingent consideration. To
the extent sales of Cincinnati products and certain similar products of the
Company during calendar years 1996 and 1997 exceed Cincinnati's historical sales
volume, the Company will pay the former Cincinnati shareholders an amount equal
to 10.0% of the first $1.0 million of such excess, and 4.0% of any additional
excess. All payments of such contingent consideration for calendar years 1996
and 1997 to the former majority shareholder, who will receive 53.6% of such
payments, shall be paid in shares of Common Stock valued at their then fair
market value. The remainder of this contingent consideration paid to the other
former shareholders shall be paid in cash. No contingent consideration was
earned with respect to 1996. To the extent net sales of the Company in calendar
years 1998, 1999 and 2000 exceed certain base targets, the former majority
shareholder of Cincinnati will receive 1.25% of such excess, 50.0% of which
shall be paid in cash and 50.0% of which shall be paid in shares of Common
Stock, valued at their then fair market value. The Company may, at its election,
buy-out the payments of future contingent consideration due to the former
majority shareholder for calendar years 1998, 1999 and 2000. The specified
payments range from $2.0 million to $1.0 million depending on the timing of such
a buy-out.
    
 
    Pursuant to a registration rights agreement entered into in connection with
the Cincinnati Transaction, the Company granted certain piggy-back registration
rights to the former majority shareholder with respect to the shares of Common
Stock issued to him. See "Shares Eligible for Future Sale -- Registration
Rights."
 
    The Cincinnati Transaction was accounted for under the purchase method of
accounting. For a further discussion of the accounting treatment of the
Cincinnati Transaction and certain accounting charges in connection therewith,

Operations -- Overview."

                              CERTAIN TRANSACTIONS
 
    The Company is a party to a lease agreement, dated March 26, 1992, as
amended in December, 1996, with J&N Partnership, an Illinois general partnership
owned by Messrs. Sparacino and Gihl and Mr. Sparacino's sons and daughter (Mr.
Gihl's spouse), pursuant to which the Company leases its principal 39,000 square
foot office and manufacturing facility located in Melrose Park, Illinois. Annual
rent under the lease is $144,000 plus property taxes, insurance and utilities,
and the lease terminates in April 2002. The Company has also agreed pursuant to
the terms of the lease agreement to pay all expenses relating to occupancy and
maintenance of the leased premises.
 
   
    At December 31, 1996, the Company was indebted to Mr. Sparacino, the
Company's co-founder and Chairman Emeritus, in the amount of $200,000, reflected
by an unsecured promissory note bearing interest at a rate equal to 10.0% per
annum. All principal and interest on this note is payable in December 1997.
    
 
   
    At December 31, 1996, Mr. Gihl, an executive officer and significant
shareholder of the Company, was indebted to the Company in the amount of
$188,000 pursuant to two promissory notes bearing interest at a rate per annum
equal to 1.0% above the prime rate, maturing on December 16, 1998. Interest is
being accrued quarterly under these notes, and all amounts outstanding under
these notes are secured by a pledge of Mr. Gihl's shares of Common Stock.
    
 
   
    The Company purchases all of the flat panel display screens that are the
principal hardware component incorporated in its graphics-based operator
interface product line from Digital Electronics, which owns 380,001 shares of
Common Stock, representing 7.8% of the outstanding Common Stock, and owns 39.0%
of the Taylor Class A Shares. Keizo Wada, the President and Chairman of Digital
Electronics, owns 18,000 shares of the Common Stock of the Company. Hardware
purchases by the Company from Digital Electronics totaled $3.1 million, $6.2
million, $8.8 million and $8.1 million for fiscal 1994, 1995 and 1996 and the
nine months ended December 31, 1996, respectively. Mr. Gihl is a member of the
Board of Directors of Digital Electronics. See "Risk Factors -- Dependence Upon
Digital Electronics Corporation."
    
 
    In December 1996, Taylor entered into a two-year consulting agreement with
Digital Electronics whereby Digital Electronics has agreed to provide certain
product development and marketing consulting services to Taylor in exchange for
compensation of $200,000 per year. This agreement terminates in November 1998.
 
    For information regarding certain transactions between the Company, Taylor,
Mr. Siemer and Digital Electronics in connection with the Taylor Transaction,
see "Recent Acquisitions -- Taylor Transaction."
 
    Pursuant to a distribution agreement dated April 1, 1995, the Company has
the exclusive right to market and distribute in North and South America all of
Digital Electronics' hardware products. The distribution agreement expires on
April 1, 2005.
 
    On July 22, 1994, Moritani America, Inc. ("Moritani America") and Digital
Electronics each purchased 125,001 shares of Common Stock of the Company for a
purchase price of $125,000 with a total of 250,002 shares of Common Stock being
sold for an aggregate purchase price of $250,000. Moritani America (which,
together with its parent, Moritani & Co., owns an aggregate of 291,501 shares of
the Company's Common Stock) acts as the import broker of Digital Electronics'
products on behalf of the Company. Under the terms of this transaction, Moritani
America and Digital Electronics have the right to require the Company at any
time to purchase all, but not less than all, of the shares purchased by each of
them under this transaction for a price equal to the lesser of (i) the original
purchase price, or (ii) the net book value per share as reflected on the
Company's consolidated balance sheet for the fiscal quarter most recently
completed. Moritani America and Digital Electronics have agreed to waive this
right effective upon the closing of this offering.
 
                                       45
<PAGE>
   
    In November 1995, the Company purchased a 40.0% interest in ProFace, a joint
venture among the Company, Digital Electronics and Moritani America. ProFace, an
industrial automation products distributor located in the Netherlands,
distributes the Company's and Digital Electronics' products in Europe. This
investment is accounted for by the Company under the equity method. ProFace did
not have significant operations during fiscal 1996. For the nine months ended
December 31, 1996, the Company's share of net earnings of the joint venture was
$79,000.
    
 
   
    Neil Taylor, a director of the Company and its Senior Vice President of
Software Development, together with his wife, received a $2.2 million note, $3.7
million in cash, 575,334 Taylor Exchangeable Shares and the right to receive
certain contingent consideration in connection with the Taylor Transaction.
Prior to the Taylor Transaction, Neil Taylor and his wife loaned Taylor an
aggregate of $230,000. These loans bear interest at the Canadian prime rate. The
Company will repay this indebtedness with a portion of the proceeds of this
offering. See "Recent Acquisitions -- Taylor Transaction."
    
 
    On December 16, 1993, the Company sold 1,204,653 shares of its Common Stock
to Mr. Siemer for a purchase price of $1.0 million. The agreement relating to
this purchase provides, among other things, that if the Company fails to effect
an initial public offering of its Common Stock or sale of the Company prior to
December 16, 1998, Mr. Siemer may require the Company to repurchase such
1,204,653 shares at their then fair market value. This right will terminate upon
the effectiveness of this offering. In connection with this transaction, the
Company entered into a shareholder agreement among the Company, Mr. Siemer and
the Company's other shareholders, pursuant to which, among other things, the
shareholders of the Company granted certain voting rights to Mr. Siemer. For so
long as Mr. Siemer owns a majority of the shares purchased in the transaction,
each of the shareholders agreed to vote all shares owned by them in favor of Mr.
Siemer's nominee to the Board of Directors. In addition, the shareholders agreed
to reciprocal rights of first refusal in the event of a proposed transfer of
shares and to certain preemptive rights with respect to the issuances of new
securities by the Company. The shareholder agreement and the rights granted to
Mr. Siemer pursuant to his stock purchase agreement will automatically terminate
upon the effectiveness of the registration statement filed in connection with
this offering. Mr. Siemer also holds certain registration rights with respect to
his shares of Common Stock. See "Description of Capital Stock -- Registration
Rights."
 
   
    In July 1996, a company controlled by Mr. Siemer purchased from the Company
certain inventory and manufacturing rights relating to a text-based operator
interface product line for approximately $46,000. In addition, the Company and
Mr. Siemer have agreed to purchase arrangements permitting the company
controlled by Mr. Siemer to purchase designated Company products from time to
time at a prescribed mark-up from the Company's cost.
    
 
    For information regarding other transactions between Mr. Siemer and the
Company, see "Recent Acquisitions -- Taylor Transaction."
 
    The Company's Board of Directors has adopted a policy that any future
transactions between the Company and its officers, directors, affiliates or
controlling shareholders will be on terms which are considered to be no less
favorable to the Company than those obtainable in arm's length transactions with
unaffiliated third parties and must be approved by a majority of the
disinterested directors.

                          DESCRIPTION OF CAPITAL STOCK
 
   
    The authorized capital stock of the Company consists of 22,500,000 shares of
Common Stock, no par value per share, and 1,000,000 shares of Preferred Stock,
no par value per share. Immediately prior to the closing of this offering, after
giving effect to the Taylor Conversion, the PIK Issuance and the Debenture
Conversion, there will be 6,003,576 shares of Common Stock issued and
outstanding and held by 18 shareholders of record. Upon the closing of this
offering, there will be no shares of Preferred Stock outstanding.
    
 
COMMON STOCK
 
    The holders of shares of Common Stock are entitled to one vote for each
share held of record on all matters on which shareholders are entitled or
permitted to vote. Such holders may not cumulate votes in the election of
directors. Accordingly, holders of a majority of the shares of Common Stock
entitled to vote in any election of directors may elect all the directors
standing for election. The holders of Common Stock are entitled to receive such
dividends as may lawfully be declared by the Board of Directors out of funds
legally available therefor and to share pro rata in any other distribution to
the holders of Common Stock, subject to any preferential dividend rights of any
Preferred Stock then outstanding. See "Dividend Policy." The holders of Common
Stock are entitled to share ratably in the assets of the Company remaining after
payment of liabilities in the event of any liquidation, dissolution or winding
up of the affairs of the Company, subject to the prior rights of any Preferred
Stock then outstanding. The holders of Common Stock have no preemptive rights.
There are no conversion rights, redemption or sinking fund provisions or fixed
dividend rights with respect to the Common Stock. All outstanding shares of
Common Stock are fully paid and non-assessable, and the shares of Common Stock
to be issued in this offering, upon payment therefor, will be fully paid and
non-assessable. The rights, preferences and privileges of holders of Common
Stock are subject to, and may be adversely affected by, the rights of holders of
shares of any series of Preferred Stock which the Company may designate and
issue in the future.
 
PREFERRED STOCK
 
    The Company's Articles of Incorporation authorize the Board of Directors,
without shareholder approval, to issue shares of Preferred Stock in classes or
series and to establish the designations, preferences, qualifications,
limitations or restrictions of any class or series with respect to the rate and
nature of dividends, the price and terms and conditions on which shares may be
redeemed, the terms and conditions for conversion or exchange into any other
class or series of the stock, voting rights and other terms. The Company may
issue, without approval of the holders of Common Stock, shares of Preferred
Stock which have voting, dividend or liquidation rights superior to the shares
of Common Stock and which may adversely affect the rights of holders of shares
of Common Stock. The issuance of shares of Preferred Stock, while providing
flexibility in connection with possible acquisitions and other corporate
purposes, could, among other things, adversely affect the voting power of the
holders of shares of Common Stock and could have the effect of discouraging,
delaying, deferring or preventing a change in control of the Company. The
Company has no present plan to issue any shares of Preferred Stock.
 
TAYLOR EXCHANGEABLE SHARES
 
    As part of the Taylor Transaction, the Company caused Taylor to issue
767,112 shares of Class C Exchangeable Shares to the former shareholders of
Taylor (the "Taylor Exchangeable Shares"). The Taylor Exchangeable Shares have
no voting rights or any right to dividends or distributions or to share in the
assets of Taylor upon its liquidation. Each Taylor Exchangeable Share is
convertible at any time into one share of Common Stock of the Company.
 
                                       49
<PAGE>
CONVERTIBLE SUBORDINATED DEBENTURE
 
    In September 1987, the Company issued a 6.0% Convertible Subordinated
Debenture to a shareholder of the Company in the principal amount of $300,000
(the "Convertible Debenture"). Interest is payable monthly on the outstanding
principal amount of the Convertible Debenture at a rate of 6.0% per annum. At
any time prior to December 1, 1997, the holder of the Convertible Debenture may
convert all or part of the principal balance thereunder into Common Stock at a
price of $0.74 per share. In June 1996, the shareholder converted $50,000 of the
Convertible Debenture into 67,872 shares of Common Stock. The shareholder
holding the Convertible Debenture has agreed that, upon the closing of this
offering, the outstanding balance of the Convertible Debenture will be converted
into 339,366 shares of Common Stock.
 
CERTAIN STATUTORY PROVISIONS
 
    The Company is subject to Section 7.85 of the Business Corporation Act of
Illinois ("Section 7.85"). Section 7.85 prohibits a publicly held Illinois
corporation from engaging in a "business combination" with an "interested
shareholder," unless the proposed "business combination" receives (i) the
affirmative vote of the holders of at least 80% of the combined voting power of
the then outstanding shares of all classes and series of the corporation
entitled to vote generally in the election of directors (the "Voting Shares")
voting together as a single class, and (ii) the affirmative vote of a majority
of the combined voting power of the then outstanding Voting Shares held by
disinterested shareholders voting together as a single class. For purposes of
Section 7.85, a "business combination" includes a merger, asset sale or other
transaction resulting in a financial benefit to the interested shareholder, and
an "interested shareholder" is a person who, together with affiliates and
associates, owns (or within two years, did own) 10% or more of the combined
voting power of the outstanding Voting Shares.
 
CERTAIN CHARTER AND BY-LAW PROVISIONS
 
   
    The Company's Articles of Incorporation and By-laws contain a number of
provisions related to corporate governance and to the rights of shareholders. In
particular, the Company's By-laws provide that shareholders follow an advance
notification procedure for certain shareholder nominations of candidates for the
Board of Directors and for certain other shareholder business to be conducted at
any meeting of the shareholders. The existence of these provisions in the
Company's Articles of Incorporation and By-laws may have the effect of
discouraging a change in control of the Company and limiting shareholder
participation in certain transactions or circumstances by limiting shareholders'
participation to annual and special meetings of shareholders and making such
participation contingent upon adherence to certain prescribed procedures.
    
 
    In addition, the Company's Articles of Incorporation and By-laws provide
that the number of directors of the Company will be fixed at six, and unless the
Board of Directors otherwise determines, a majority of the directors then in
office may fill any vacancies on the Board of Directors. Certain provisions of
the Company's Articles of Incorporation and By-laws may impede changes in
majority control of the Board of Directors. The Company's Articles of
Incorporation provide that the Board of Directors will be divided into three
classes, with directors in each class elected for three-year staggered terms.
Thus, it would take two annual elections to replace a majority of the Company's
Board of Directors. The Articles of Incorporation further provide that directors
may be removed prior to the expiration of their terms only for cause, and that
there are no cumulative voting rights in the election of directors. The By-laws
of the Company provide that any vacancy occurring in the Board of Directors,
including a vacancy created by an increase in the number of directors, shall be
filled for the remainder of the unexpired term by a majority vote of the
directors then in office.
 
    As discussed above under "Preferred Stock," the Articles of Incorporation
authorize the creation and issuance of one or more series of Preferred Stock. In
the event of a proposed merger, tender offer or
 
                                       50
<PAGE>
other attempt to gain control of the Company that the Board of Directors does
not approve, it might be possible for the Board of Directors to authorize the
issuance of a series of Preferred Stock with rights and preferences that would
impede the completion of such a transaction. An effect of the possible issuance
of Preferred Stock, therefore, may be to deter a future takeover attempt. The
Board of Directors has no present plans or understanding for the issuance of any
Preferred Stock.
 
    The provisions of the Articles of Incorporation and the By-laws summarized
above may tend to deter any potential unsolicited or hostile takeover attempt or
other efforts to obtain control of the Company and thereby deprive some
shareholders of opportunities to sell shares of the Company at higher than
market prices.
 
LIMITATION ON LIABILITY AND INDEMNIFICATION MATTERS
 
    The Company has adopted provisions in its Articles of Incorporation that, to
the fullest extent provided under Illinois law, limit the liability of its
directors and officers for monetary damages arising from a breach of their
fiduciary duties as directors or officers. Such limitation of liability does not
affect the availability of equitable remedies such as injunctive relief or
rescission, nor does it limit liability for (i) any breach of an officer or
director's duty of loyalty to the Company or its shareholders, (ii) acts or
omissions not in good faith or which involve intentional misconduct or a knowing
violation of law, (iii) a transaction from which an officer or director derives
an improper personal benefit or (iv) an unlawful distribution to the Company's
shareholders. The Company's By-laws provide that the Company shall indemnify its
directors to the fullest extent permitted by Illinois law, including
circumstances in which indemnification is otherwise discretionary to the Company
under Illinois law and permit the Company in its discretion to similarly
indemnify its officers, employees and agents.
 
    There is no pending litigation or proceeding involving a director, officer,
employee or agent of the Company in which indemnification will be required or
permitted. The Company is not aware of any threatened litigation or proceeding
which may result in a claim for such indemnification.
 
REGISTRATION RIGHTS AGREEMENTS
 
   
    Following this offering, the holders of certain shares of Common Stock will
have certain rights to cause the Company to register those shares under the
Securities Act of 1933, as amended (the "Securities Act"). By separate
agreements, these registration rights apply to the 966,652 shares held by A.B.
Siemer, the 135,003 shares held by the former majority shareholder of
Cincinnati, and the 671,112 shares issuable to the former shareholders of Taylor
upon the conversion of Taylor Exchangeable Shares (collectively, the "Rights
Holders"). All of such registration rights agreements provide that the Rights
Holders' registration rights are subject to certain notice requirements and to
the condition that, in the case of any piggyback registration rights, the
underwriters of any offering have the right to limit the number of shares
included in such registration. The Company has agreed to bear the expenses of
these registrations under these registration rights agreements, except for
underwriting discounts, selling commissions and underwriters' expense
allowances, which are to be paid by the respective Rights Holders.
    
 
   
    Pursuant to his registration rights agreement with the Company, Mr. Siemer
was granted registration rights with respect to the 966,652 shares held by him.
At any time prior to June 1, 2003, Mr. Siemer, or the holders of 50.0% of the
shares originally purchased by Mr. Siemer, as the case may be, have the right to
require the Company to register all or part of such shares under the Securities
Act, and the Company is required to use its best efforts to effect such
registration, subject to certain conditions and limitations. The Company is
required to pay the cost for two demand registrations. In addition, Mr. Siemer's
registration rights agreement provides that in the event the Company proposes to
register any of its securities under the Securities Act at any time, Mr. Siemer
will be entitled to include all or a portion of such shares in such
registration, subject to certain exceptions. See "Certain Transactions."
    
 
                                       51
<PAGE>
    In connection with the acquisition of Cincinnati, the Company granted
certain piggyback registration rights to the former majority shareholder with
respect to his 135,003 shares of Common Stock. In general, such registration
rights agreement provides that in the event the Company proposes to register any
of its securities under the Securities Act at any time after January 29, 1998,
the former majority shareholder will be entitled to include all or a portion of
his shares in such registration, subject to certain exceptions. Such
registration rights only apply in the case of a registration effective on or
after January 29, 1998.
 
   
    Finally, as part of the Taylor Transaction, the Company granted certain
registration rights to the holders of Taylor Exchangeable Shares, exercisable
upon the conversion of such shares into shares of Common Stock of the Company.
Such rights are exercisable commencing seven months after the effective date of
an initial public offering of any class of the Company's securities, and expire
five years thereafter. The former shareholders of Taylor are entitled to require
the Company, on up to four occasions during such period, to register all or a
portion of such shares under the Securities Act, provided that the amount of
stock to be offered in such registrations must constitute over 2% of the
Company's outstanding Common Stock and have a fair market value over $1.0
million. If the holding period for any Taylor Exchangeable Shares is determined
by the Company to be not identified with the holding period under Rule 144(d)
under the Securities Act for the shares issuable upon conversion of the Taylor
Exchangeable Shares, then certain former shareholders of Taylor are entitled to
an additional demand registration. The Company also granted to the former
shareholders of Taylor certain piggyback registration rights pursuant to which,
in the event the Company proposes to register any of its securities under the
Securities Act at any time, except in the Company's initial public offering,
such holders will be entitled to include all or a portion of their shares in
such registration, subject to certain exceptions. Finally, registration rights
for any of such shares subject to the registration rights agreement expire once
the holder of such shares is permitted to transfer all of his shares in any
three month period pursuant to Rule 144 under the Securities Act.
    
 
TRANSFER AGENT
 
   
    The transfer agent and registrar for the Common Stock will be Norwest Bank
Minnesota, N.A.

                        SHARES ELIGIBLE FOR FUTURE SALE
 
   
    Upon completion of this offering, the Company will have outstanding
7,653,576 shares of Common Stock. Of these shares, the 2,750,000 shares of
Common Stock sold in this offering will be freely tradeable without restriction
under the Securities Act except for any shares purchased by "affiliates" of the
Company (as that term is defined in Rule 144 under the Securities Act), which
may generally only be sold in compliance with Rule 144.
    
 
   
    The remaining 4,903,576 shares (the "Restricted Shares") were issued and
sold by the Company in private transactions in reliance upon exemptions under
the Securities Act. Restricted Shares generally may be sold in the public market
only if registered under the Securities Act or sold in compliance with Rule 144.
    
 
   
    Of the Restricted Shares, 288,000 shares will be eligible for sale in the
public market in reliance on Rule 144(k) immediately following the closing of
this offering; all of these shares are subject to the lock-up agreements
described below. An additional 3,192,224 Restricted Shares will be eligible for
sale in the public market pursuant to Rule 144 and Rule 701 under the Securities
Act beginning approximately 90 days after the date of this Prospectus; all of
these shares are subject to the lock-up agreements described below.
    
 
   
    Each executive officer, director and director nominee and all of the current
shareholders of the Company, who will, upon the closing of this offering, hold
an aggregate of 6,003,576 shares of Common Stock, together with the holders of
stock options to purchase an aggregate of 295,974 shares of Common Stock, have
agreed that they will not, without the prior written consent of Adams, Harkness
& Hill, Inc., offer, sell, contract to sell or otherwise dispose of any shares
of Common Stock owned beneficially by them, other than as a bona fide gift or
gifts to or in trust for a person or entity who or which agrees in writing to be
bound by the foregoing restrictions, for a period of 180 days after the date of
this Prospectus.
    
 
   
    In general, under Rule 144 as currently in effect, a person (or persons
whose shares are aggregated), including persons deemed to be affiliates of the
Company, whose Restricted Shares have been fully paid for and held for at least
two years from the later of the date of issuance by the Company or acquisition
from an affiliate of the Company, may sell such securities in brokers'
transactions or directly to market makers beginning approximately 90 days after
the date of this Prospectus, provided the number of shares sold in any
three-month period does not exceed the greater of 1% of the then outstanding
shares of the Common Stock (approximately 76,540 shares, based on the number of
shares to be outstanding after this offering) or the average weekly trading
volume in the public market during the four calendar weeks preceding the filing
of the seller's Form 144. Sales under Rule 144 are also subject to certain
notice of sale requirements and the availability of current public information
concerning the Company. After three years have elapsed from the later of the
issuance of Restricted Shares by the Company or their acquisition from an
affiliate of the Company, such shares may be sold without limitation, pursuant
to Rule 144(k), by persons who have not been affiliates of the Company for at
least three months. Rule 144 also provides that affiliates who are selling
shares that are not Restricted Shares must nonetheless comply with the same
restrictions applicable to Restricted Shares with the exception of the holding
period requirement.
    
 
    Restricted Shares that have been issued in reliance on Rule 701 (such as
shares of Common Stock issued under the Company's 1993 Stock Option Plan) may be
resold by persons other than affiliates of the Company, beginning approximately
90 days after the date of this Prospectus, subject only to the manner of sale
provisions of Rule 144, and may be resold by affiliates of the Company under
Rule 144 without compliance with its two-year holding period requirement.
 
    Rule 144A under the Securities Act would permit, subject to certain
conditions, the sale by the current holders of Restricted Shares of all or a
portion of their shares to certain "qualified institutional buyers," as defined
in Rule 144A.

    Certain shareholders of the Company hold registration rights. See
"Description of Capital Stock -- Registration Rights Agreements."
 
   
    At January 31, 1997, the Company had outstanding options for 295,974 shares
of Common Stock, of which 159,194 will be exercisable as of February 9, 1997
(all of which are subject to lock-up agreements). In addition, the Company
intends to grant, immediately following the effectiveness of this offering,
options to purchase an aggregate of 300,000 shares of Common Stock at an
exercise price equal to the initial public offering price per share in this
offering. The Company intends to file Form S-8 registration statements under the
Securities Act to register all shares of Common Stock issuable under its stock
plans, which it has agreed not to file sooner than 180 days after the date of
this Prospectus without the consent of Adams, Harkness & Hill, Inc. Those
registration statements will become effective immediately upon filing. Shares
issued pursuant to those registration statements will be eligible for resale in
the public market, subject to the Rule 144 limitations applicable to affiliates
of the Company.
    
 
    Prior to this offering there has been no public market for the Common Stock
of the Company and no prediction can be made as to the effect, if any, that
market sales of shares or the availability of shares for sale will have on the
market price of the Common Stock prevailing from time to time. Nevertheless,
sales of substantial numbers of shares of Common Stock in the public market
could adversely affect the market price of the Common Stock and could impair the
Company's ability to raise capital through a sale of its equity securities.

    Under the terms and conditions of the Underwriting Agreement, the
Underwriters are committed to take and pay for all shares offered hereby, if any
are taken.
 
    The Underwriters propose to offer the shares of Common Stock in part
directly to the public at the initial public offering price set forth on the
cover page of this Prospectus, and in part to certain securities dealers at such
price less a concession not in excess of $    per share. The Underwriters may
allow, and such dealers may reallow, a concession not in excess of $    per
share to certain brokers and dealers. After the shares of Common Stock are
released for sale to the public, the offering price and other selling terms may
from time to time be varied by the Representatives.
 
    The Company has granted the Underwriters an option exercisable for 30 days
after the date of this Prospectus to purchase up to an aggregate of 412,500
additional shares of Common Stock to cover over-allotments, if any. If the
Underwriters exercise their over-allotment option, the Underwriters have
severally agreed, subject to certain conditions, to purchase approximately the
same percentage thereof that the number of shares to be purchased by each of
them, as shown in the foregoing table, bears to the 2,750,000 shares of Common
Stock offered hereby. The Underwriters may exercise such option only to cover
over-allotments in connection with the sale of the 2,750,000 shares of Common
Stock offered hereby.
 
   
    The Company has agreed not to offer, sell, contract to sell or otherwise
dispose of any shares of Common Stock for a period of 180 days after the date of
this Prospectus without the prior written consent of Adams, Harkness & Hill,
Inc., except for the shares of Common Stock offered hereby and except that the
Company may issue securities pursuant to the Company's stock plans. The
Company's officers, directors and certain other holders of Common Stock,
including the Selling Shareholders, who will hold in the aggregate 4,903,576
shares of Common Stock following the offering, have agreed with the Underwriters
not to offer, sell, contract to sell or otherwise dispose of any shares of
Common Stock owned beneficially by them, other than as a bona fide gift or gifts
to or in trust for a person or entity who or which agrees in writing to be bound
by the foregoing restrictions, for a period of 180 days after the date of this
Prospectus, without the prior written consent of Adams, Harkness & Hill, Inc.
    
 
    The Representatives have advised the Company that the Underwriters do not
intend to confirm sales to any account over which they exercise discretionary
authority.

    Prior to this offering, there has been no public market for the Common
Stock. The initial public offering price will be negotiated among the Company
and the Representatives. Among the factors to be considered in determining the
initial public offering price of the Common Stock, in addition to prevailing
market conditions, will be the Company's historical performance, estimates of
the business potential and earnings prospects of the Company, an assessment of
the Company's management and the consideration of the above factors in relation
to market valuation of companies in related businesses.
 
   
    The Common Stock has been approved for quotation and trading on the Nasdaq
National Market under the symbol "TCPS."
    
 
    The Company and the Selling Shareholders have agreed to indemnify the
several Underwriters against or contribute to losses arising out of certain
liabilities, including liabilities under the Securities Act.
 
                                 LEGAL MATTERS
 
    The validity of the shares of Common Stock offered hereby will be passed
upon for the Company by D'Ancona & Pflaum, Chicago, Illinois. Certain legal
matters will be passed upon for the Underwriters by Hale and Dorr, Boston,
Massachusetts.

To the Shareholders of

    We have audited the accompanying consolidated balance sheets of Total
Control Products, Inc. (an Illinois Corporation) and Subsidiaries as of March
31, 1995 and 1996 and December 31, 1996 and the related consolidated statements
of operations, shareholders' equity (deficit) and cash flows for each of the
three years in the period ended March 31, 1996 and for the nine months ended
December 31, 1996. 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 principals 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 financial statements referred to above present fairly,
in all material respects, the financial position of Total Control Products, Inc.
and Subsidiaries as of March 31, 1995 and 1996 and December 31, 1996, and the
results of their operations and their cash flows for each of the three years in
the period ended March 31, 1996 and for the nine months ended December 31, 1996,
in conformity with generally accepted accounting principles.

1. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES
 
    (A) DESCRIPTION OF BUSINESS
 
   
    Total Control Products, Inc., an Illinois corporation, together with its
wholly owned subsidiary, Tara Products, Inc., d/b/a Total Control - Cincinnati,
an Illinois corporation, and its majority-owned subsidiary, Taylor Industrial
Software Inc., an Alberta corporation ("Taylor"), (collectively the "Company"),
designs, develops and markets products and technology for the control segment of
the industrial automation marketplace.
    
 
    (B) PRINCIPLES OF CONSOLIDATION
 
    The consolidated financial statements include the accounts of Total Control
Products, Inc. and its wholly owned subsidiary since its acquisition on January
29, 1996 and its majority-owned subsidiary since its acquisition on September
26, 1996. In connection with the Taylor transaction, the Company sold 39% of the
Taylor Class A Shares to Digital Electronics Corporation ("Digital
Electronics"), located in Osaka, Japan, which is the Company's largest supplier
(see Note 11), for an aggregate purchase price of $4.0 million. As a result, a
minority interest for 39% of the net income or loss of Taylor is recorded on the
Company's statement of operations. The Company's ownership of Taylor Class A
Common Shares may increase up to 4% based on the amount of contingent
consideration paid by the Company in connection with the acquisition. All
intercompany items and transactions have been eliminated in consolidation.
 
    Additionally, the Company accounts for its 40% ownership interest in a
foreign joint venture on the equity method.
 
    (C) REVENUE RECOGNITION
 
    Net sales include revenues from operator interface products, software
license fees, software maintenance and services. Revenue from product sales and
software licenses are recognized upon shipment of the product to customers,
provided that there are no significant obligations remaining and collectibility
of the revenue is probable. The Company provides for estimated product returns
upon shipment of the products. Revenue from software maintenance contracts is
recognized ratably as it is earned over the term of the contract, generally one
year. Unearned software maintenance revenue is included in deferred revenue.
Service revenue is recognized as the service is provided. The Company recognizes
revenue from software license fees, service and maintenance in accordance with
the provisions of the American Institute of Certified Public Accountants,
Statement of Position No. 91-1 (SOP 91-1), Software Revenue Recognition.
 
    (D) CASH AND CASH EQUIVALENTS

original maturities of three months or less), principally time deposits and
other short term securities which are stated at cost, which approximates fair
value.

("goodwill"). Such goodwill is being amortized on a straight-line basis over a
period ranging from seven to fifteen years. The accumulated amortization of
intangible assets amounted to approximately $23,000 and $215,000 as of March 31,
1996 and December 31, 1996, respectively.
    
 
   
    The Company reviews goodwill for impairment whenever events or changes in
circumstances indicate that its carrying amount may not be recoverable. To date,
no such events or changes in circumstances have occurred. If such events or
changes in circumstances occur, the Company will recognize an impairment loss if
the undiscounted future cash flows expected to be generated by the acquired
business are less than the carrying value of the related goodwill. The
impairment loss in such instances would adjust the goodwill to its fair value.
    
 
    (I) FOREIGN CURRENCY TRANSLATION ADJUSTMENTS
 
    The Company follows the translation principles established by Statement of
Financial Accounting Standards ("SFAS") No. 52, "Foreign Currency Translation".
The net assets of the Company's majority-owned subsidiary and the Company's
investment in its foreign joint venture are translated at the exchange rate in
effect at the end of the periods presented. The revenues and expenses of the
Company's

1. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (CONTINUED)
   
majority-owned subsidiary and the Company's ownership percentage of the foreign
joint venture's net income are translated at the average rates in effect during
the period. The Company's foreign joint venture had no significant activity for
the year ended March 31, 1996. Included in other income is the Company's 40%
share of the earnings of the foreign joint venture for the nine months ended
December 31, 1996 of approximately $79,000. See Note 6 for a discussion of the
Company's policy regarding certain foreign currency hedging transactions.
    
 
    (J) RESEARCH AND DEVELOPMENT
 
    The Company records its software development costs in accordance with SFAS
No. 86. Accordingly, these costs are expensed until the technological
feasibility of the software has been established. Thereafter, all significant
software development costs are capitalized until the product is available for
general release to customers. Subsequently, these costs are reported at the
lower of unamortized cost or net realizable value. As a result of market and
other business conditions, the time between establishment of technological
feasibility and general release has not been significant since April 1, 1993.
Accordingly, the Company has not capitalized any software development costs
during this time. During fiscal 1994, because of technological, industry and
business changes, the Company shortened its estimate of the useful life of
software development costs that were capitalized at March 31, 1993. As a result,
the Company amortized the remaining net book value of these software development
costs during fiscal 1994, which resulted in an amortization expense of
approximately $466,000.
 
    (K) INCOME TAXES
 
    The Company accounts for income taxes under the provisions of SFAS No. 109,
"Accounting for Income Taxes." Deferred taxes are determined based on the
estimated future tax effects of differences between the financial statement and
tax basis of assets and liabilities under the provisions of the enacted tax
laws.
 
    (L) MANAGEMENT'S USE OF 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 sales and expenses during the period.
Actual results could differ from those estimates.
 
    (M) FINANCIAL INSTRUMENTS AND CONCENTRATION OF CREDIT RISK
 
   
    Effective April 1, 1995, the Company adopted the provisions of SFAS No. 115,
"Accounting for Certain Investments in Debt and Equity Securities." The adoption
of SFAS No. 115 did not have a material impact on the Company's financial
statements.
    
 
    The carrying value for current assets and current liabilities reasonably
approximates fair value due to the short maturity of these items. Since the
Company's long-term debt is not publicly quoted, fair value

1. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (CONTINUED)
   
estimates are based on each obligation's characteristics, including remaining
maturities, interest rate, credit rating, collateral, amortization schedule and
liquidity. The carrying amount for long-term debt other than the convertible
subordinated debentures approximates fair value. Recent company transactions
provide an indication that the fair value of the convertible subordinated
debentures is approximately $3.0 million.
    
 
   
    Financial instruments that potentially subject the Company to concentration
of credit risk consist principally of cash investments and trade receivables.
The Company has cash investment policies that limit cash investments to
short-term low risk investments. With respect to trade receivables, the Company
grants unsecured credit to its customers. In doing so, the Company performs
ongoing credit evaluations of its customers' financial condition. A substantial
portion of accounts receivable is from customers located throughout the United
States. One customer accounted for approximately 14%, 14% and 10% of the
Company's net sales for fiscal 1994, 1995 and 1996, respectively, and
approximately 10% and 9% of the Company's net sales for the nine months ended
December 31, 1995 and 1996, respectively. Additionally, the Company establishes
accounts receivable allowances based upon factors relating to the credit risk of
specific customers, historical trends and other information.
    
 
    (N) ACCRETION TO REDEMPTION VALUE OF COMMON STOCK
 
    Accretion to redemption value of redeemable common stock represents the
change in the redemption value of outstanding common stock in each period. The
redemption values for certain common shares are based on (i) fair market values
of the class of stock or (ii) fixed amounts (See Note 7).
 
    (O) STOCK SPLITS
 
    In December 1996, the Company's Board of Directors declared a three-for-one
split of the Company's Common Stock, which has been retroactively reflected in
the accompanying consolidated financial statements. In December 1996, Taylor's
Board of Directors declared a three-for-one split of Taylor's Class C
Exchangeable Common Stock, which has been retroactively reflected in the
accompanying consolidated financial statements.
 
    (P) NET INCOME (LOSS) PER SHARE AVAILABLE TO SHAREHOLDERS AND PRO FORMA AND
     SUPPLEMENTAL PRO FORMA NET INCOME (LOSS) PER SHARE
 
    Net income (loss) per share available to shareholders is based on the
weighted average number of shares of common stock and common stock equivalents
outstanding, as adjusted for the stock split described above for all periods
presented. Common stock equivalents represent options, convertible stock and
convertible debt using the treasury stock method for all periods presented. Any
common stock options and convertible stock issued from one year prior to the
initial public filing with a price below the estimated initial public offering
price have been included as outstanding shares for all periods presented reduced
by the number of shares which could be purchased with proceeds from the exercise
of the options.

1. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (CONTINUED)
    Pro forma net income (loss) per share is computed based upon pro forma net
income (loss) as described below and the weighted average number of shares
adjusted for the conversion of $250,000 of convertible debentures into 339,366
shares of Common Stock and the dilutive effect of any common stock equivalents,
as appropriate.
 
   
    Supplemental pro forma net income (loss) per share for fiscal 1996 and the
nine months ended December 31, 1996 of $0.18 and $(0.26), respectively, is
computed based upon (i) pro forma net income adjusted for the reduction in
interest expense, net of tax benefit of approximately $117,000 and $260,000 for
fiscal 1996 and the nine months ended December 31, 1996, respectively, resulting
from the application of the net proceeds of the contemplated offering to reduce
indebtedness of the Company and (ii) the pro forma weighted average number of
shares of Common Stock outstanding adjusted to reflect the sale by the Company
of approximately 292,000 and 1,040,000 shares of Common Stock in the offering
resulting in net proceeds sufficient to pay such indebtedness for fiscal 1996
and the nine months ended December 31, 1996, respectively.
    
 
    (Q) INTERIM FINANCIAL DATA
 
   
    In management's opinion, the unaudited interim financial statements for the
nine months ended December 31, 1995 are presented on a basis consistent with the
audited financial statements, and all adjustments, consisting only of normal
recurring adjustments, which are necessary to present fairly the operating
results have been reflected. The results of operations for interim periods are
not necessarily indicative of operations for the full fiscal year.
    
 
    (R) PRO FORMA BALANCE SHEET AND STATEMENTS OF OPERATIONS
 
   
    Pursuant to the rules and regulations of the Securities and Exchange
Commission, the accompanying unaudited pro forma consolidated statements of
operations for the year ended March 31, 1996 and the nine months ended December
31, 1996 reflect the change in net income available to common shareholders
resulting from the following events which will occur upon completion of the
offering contemplated by this prospectus: (i) the automatic termination of the
redemption provision of redeemable common stock; (ii) the conversion of $250,000
of subordinated debentures into 339,366 shares of the Company's Common Stock;
and (iii) the issuance of 27,999 shares of Common Stock required upon the
retirement of the $2.0 million shareholder note payable which will be repaid
with a portion of the proceeds of the offering. Additionally, the accompanying
pro forma balance sheet as of December 31, 1996 reflects the change in
capitalization attributable to the above pro forma adjustments as if the
offering had closed on December 31, 1996 (excluding the effects of the offering
proceeds), and including the reclassification from long-term to short-term of a
$2.0 million note payable, which becomes due 10 days after the completion of the
offering. See Notes 5 and 7.
    
 
   
    (S) DEFERRED OFFERING COSTS
    
 
   
    As of December 31, 1996, the Company had incurred approximately $265,000 in
costs related to the Company's proposed initial public offering. These costs
have been capitalized and are included in other

long-term assets in the accompanying consolidated balance sheet at December 31,
1996. Upon completion of the Company's proposed initial public offering, the
deferred offering costs will be reclassified to Common Stock as a reduction to
the proceeds from the offering.
    
 
2. ACQUISITIONS
 
   
    On January 29, 1996, Total Control Products, Inc. acquired 100% of the
outstanding stock of Cincinnati Dynacomp, Inc. ("Cincinnati"), a manufacturer
and distributor of text based operator interface products, for $499,990 and
150,003 shares of the Company's Common Stock (which was assigned a fair value of
$500,010) and merged Cincinnati into its wholly owned subsidiary. Additionally,
the former shareholders of Cincinnati are entitled to contingent cash and Common
Stock consideration. To the extent calendar year 1996 and 1997 sales of
Cincinnati and certain similar Company products exceed its historical sales
volume, the contingent consideration is equal to 10% for the first $1.0 million
of such excess and 4% of any further excess. There was no contingent
consideration earned for calendar 1996. All payments of such contingent
consideration for calendar year 1997 to the former majority shareholder, who
will receive 53% of such consideration, shall be paid in shares of Common Stock
valued at their then fair market value, and the remainder to be paid to the
other former shareholders shall be paid in cash. To the extent calendar year
1998, 1999 and 2000 sales of the Company exceed approximately $32.0 million in
any of those years, the former majority shareholder of Cincinnati receives 1.25%
of such excess of which 50% shall be paid in cash and 50% shall be paid in
shares of the Company valued at their then fair market value, with the agreement
providing the Company a buy-out option related to this contingent consideration
ranging from $1.0 million to $2.0 million depending on the timing of such
prepayment. All contingent consideration is due 90 days after the end of the
respective calendar years on which such consideration was based.
    
 
   
    This acquisition was accounted for using the purchase method. Accordingly,
the purchase price was allocated to the net assets acquired based on their
estimated fair values. This treatment resulted in approximately $1.98 million of
cost in excess of net assets acquired at the date of acquisition. In December
1996, goodwill increased by approximately $300,000 primarily as a result of the
Company revising its estimate of the costs to exit the Cincinnati facility in
connection with the Company's integration plan established at the acquisition
date. Such excess (which will increase for any future contingent consideration
paid) is being amortized on a straight-line basis over 15 years. Cincinnati's
results of operations have been included in the consolidated results of
operations since the date of acquisition.
    
 
    In fiscal 1996, the Company made an investment in a foreign joint venture,
which distributes industrial automation tools, including the Company's products.
The Company owns 40% of this joint venture, which is located in the Netherlands
and sells products throughout Europe, with the remaining 60% owned by the
Company's largest vendor (see Notes 7 and 11) and the distributor of this
vendor's product (see Note 7). This investment is accounted for under the equity
method.
 
    On September 19, 1996, the Company entered into an agreement to acquire a
controlling interest in Taylor, a developer and marketer of industrial
automation software products located in Edmonton, Alberta. The transaction was
consummated on September 26, 1996 and the results of operations have

been included since that date. In exchange for 100% of the outstanding voting
shares of common stock of Taylor, the Company paid $7,389,817, which included
$2.2 million in the form of a note payable to the former principal shareholder,
and 767,112 shares of Class C Exchangeable common stock of Taylor (convertible
into 767,112 shares of the Company's Common Stock; see Note 7 for a description
of the features of the stock). In addition, the agreement provides for the
payment of a contingent cash consideration based on future revenues of Taylor.
To the extent the revenues of Taylor exceed $8.0 million in any of the two 12
month periods following the acquisition, the Taylor shareholders will receive
$1.0 million due 90 days after that respective 12 month period. Additionally,
the Taylor shareholders will receive cash consideration in the amount of 50% of
the revenue of Taylor in excess of $9.2 million and $10.6 million for the first
and second 12 month period after the acquisition, respectively, with the total
consideration capped at $3.0 million for any 12 month period related to this
provision. As further discussed in Note 7, the 767,112 shares of Taylor Class C
Exchangeable common stock may be redeemed at the holders' option for $6.0
million (payable over a 3 year period) to the extent Total Control Products,
Inc. has not completed an initial public offering of its Common Stock within 12
months from the date of acquisition. The $4.65 million value assigned to the
767,112 shares of Class C Exchangeable common stock was based on management's
estimate of fair value, primarily based on the present value of the potential
redemption of the security as well as recent securities transactions. The
Company also incurred approximately $600,000 in direct expenses related to the
acquisition. The acquisition was accounted for using the purchase method.
Accordingly, the purchase price was allocated to assets acquired based on their
estimated fair values.
    
 
    In connection with the transaction, the Company sold 39% of the Class A
voting shares of Taylor for $4.0 million to Digital Electronics. To the extent
the contingent consideration described above is earned, the Company is required
to contribute as equity into Taylor a portion of the earnout payment and receive
additional equity interest in Taylor up to a maximum of 4% based on a formula
outlined in a letter of understanding between the Company and Digital. The $4.0
million investment in Taylor by Digital was greater than 39% of the equity of
the subsidiary, and this difference of approximately $600,000 was charged
against goodwill to properly reflect the Company's cost of the Taylor
acquisition.
 
   
    In connection with the acquisition of Taylor, the Company engaged a broker
to commence the sale of one of the developed software product lines acquired.
The purchase price value assigned to these assets held for sale of approximately
$4.7 million is based on management's estimate of the expected gross proceeds to
be received using similar market multiples of recent sales of comparable product
lines less estimated applicable tax and direct costs of the disposal. The net
expenses in excess of revenue, (including the interest expense on related debt
expected to be retired from the proceeds from the sale of the $2.2 million note
payable described above and a $2.0 million subordinated note payable (described
in Notes 4 and 5)) of approximately $24,000 incurred by the Company since the
acquisition has not been reflected in the statement of operations of the
Company, but rather has been included in the asset held for sale. It is
management's belief that the sale of this product line will be completed by June
30, 1997. The holder of the $2.2 million shareholder note payable issued in
connection with the acquisition has the right to prohibit the sale of this
product line if the net proceeds to the Company would be less than the principal
outstanding under the note.

2. ACQUISITIONS (CONTINUED)
   
    Purchased research and development expense and other related acquisition
expenses relating to the acquisition of Taylor totaled $4.9 million and was
charged to expense as of the acquisition date in September, 1996. Of this
expense, approximately $4.7 million of the purchase price was allocated to
incomplete research and development that had not yet reached technological
feasibility and did not have a future alternative use, and was charged to
expense as of the acquisition date. The amount allocated to the purchased
incomplete research and development projects represents the estimated fair value
related to those projects determined by an independent appraisal. Proven
valuation procedures and techniques were utilized in determining the fair market
value of each intangible asset. The purchased research and development projects
were individually identified and were valued based on estimates of discounted
future income. Consideration was given to the stage of development, the time and
resources required for completion, as well as the market potential and
associated risks. To bring these projects to technological feasibility,
high-risk developmental and testing issues needed to be resolved, which required
substantial additional effort and testing.
    
 
    The remaining excess purchase price over the estimated fair value of
identified net assets (which will increase for any future contingent
consideration) of approximately $2.5 million was assigned to goodwill and is
being amortized over 7 years. These estimates are preliminary and may be changed
based on actual results.
 
   
    The following unaudited pro forma results of operations data for fiscal 1995
and 1996 and the nine months ended December 31, 1996, assume the Cincinnati
acquisition occurred as of April 1, 1994 and the Taylor acquisition occurred as
of April 1, 1995 (in thousands except per share amounts):

    In conjunction with the Company's acquisition of Cincinnati, the Company
acquired net deferred tax assets of $795,000. A portion of the acquired deferred
tax assets relates to net operating loss carry forwards ("NOLs") of
approximately $430,000, which begin to expire in 2006. These NOLs will be
limited to approximately $56,000 per year, and, at such level, it is
management's opinion that these NOLs will not expire without being fully
utilized.

    Generally, undistributed earnings of foreign subsidiaries will not be
subject to U.S. tax until distributed as dividends. Since the earnings have been
or are intended to be indefinitely reinvested in foreign operations, no
provision has been made for any U.S. taxes on the Company's portion of
undistributed earnings. Furthermore, any taxes paid to foreign governments on
those earnings may be used, in whole or in part, as credits against the U.S. tax
on any dividends distributed from such earnings. The Company's share of
undistributed earnings of its foreign joint venture recorded as of December 31,
1996 is approximately $79,000. There were no undistributed earnings from the
Company's foreign subsidiary.
    
 
    Because management believes that the deferred tax asset will be fully
realized based on current estimates of future taxable income, future reversals
of existing taxable temporary differences or available tax planning strategies,
no valuation allowance has been recorded against the deferred tax asset.
 
4. NOTES PAYABLE
 
    (A) BANK
 
    At March 31, 1996, the Company had a revolving line-of-credit agreement with
a bank which allowed borrowings up to $5.5 million ($850,000 was available at
March 31, 1996), which was due on July 31, 1997, was secured by virtually all of
the Company's assets and was personally guaranteed by certain shareholders,
limited to $2.0 million. The note carried interest at the bank's prime lending
rate (8.25% at March 31, 1996, which was also the average borrowing rate on all
short term borrowings as of March 31, 1996). Additionally, the Company had a
term loan with the bank for $1.0 million due September 30, 1996.

4. NOTES PAYABLE (CONTINUED)
   
    In July 1996, the Company entered into a new revolving line-of-credit
agreement with a bank which allows borrowings up to $9.0 million (approximately
$1.9 million was available at December 31, 1996) based on 85% of eligible
accounts receivable and 50% of eligible inventory up to a maximum of $4.5
million as specified in the agreement. This revolving credit line expires on
July 17, 1998. Interest is at LIBOR plus 2% or prime (8.25% at December 31,
1996), at the Company's option, and is due monthly. The Company retired the
previously outstanding bank loans discussed above with the proceeds from this
new bank agreement.
    
 
   
    All amounts outstanding under this agreement are secured by inventory,
receivables and all other general assets of the Company. Among other things, the
agreement requires compliance with specific financial covenants related to
tangible net worth, debt to tangible net worth ratio and cash flow coverage. As
of December 31, 1996, the Company was in compliance with these covenants.
    
 
   
    Additionally, in November 1996, the Company entered into a line-of-credit
agreement with a bank allowing for borrowing up to $1.0 million ($200,000
available at December 31, 1996) based on 80% of eligible accounts receivables of
its majority-owned subsidiary. This revolving credit line expires November 25,
1998 and bears interest at prime (8.25% at December 31, 1996) and is due
monthly. All amounts under this line are secured by the general assets of the
Company's majority-owned subsidiary. The Company retired the previously
outstanding bank line-of-credit with the proceeds from this line, which was due
on demand.
    
 
    (B) NOTES PAYABLE TO RELATED PARTIES
 
    In August 1996, the Company entered into a $1.0 million note payable with a
shareholder, Digital Electronics Corporation, which is due August 1997 or 10
days after the completion of an initial public offering of the Company's Common
Stock. Interest is at 5% per annum and is due quarterly.
 
   
    Additionally, in connection with the acquisition of its majority-owned
subsidiary, Taylor, the Company entered into a $2.2 million note payable with
the former principal shareholder of Taylor. Scheduled principal payments are
$200,000 due March 1, 1997; $200,000 due October 1, 1997; $400,000 due each
March 1, 1998, 1999, 2000 and 2001; and $200,000 due September 1, 2001. The note
may be called earlier at the holder's option upon any of the following events:
(i) delivery of a 120-day notice after March 19, 1997; (ii) 10 days after the
completion of an initial public offering; (iii) the sale of a majority of the
common stock or substantially all of the assets of the Company; or (iv) upon the
sale of Taylor's labor scheduling software product line currently held for sale
by the Company. Interest is at 12.5% for the first six months and 15% thereafter
and is due monthly. This note is subordinated to the bank notes payable. This
shareholder also has a $230,000 note payable from Taylor, due on demand after
March 31, 1997. The note is secured by the intellectual property rights in the
software product line held for sale and provides for the holder to restrict the
sale of this product line to the extent that the sale proceeds are less than the
outstanding principal balance.

    The Company has a $230,000 note payable to a Canadian governmental agency,
which bears interest at the Canadian prime rate (4.25% at December 31, 1996)
plus 3%. Scheduled monthly principal and interest payments of approximately
$16,000 are due through August 1, 1997, with the remaining due at September 1,
1997. This loan is guaranteed by the Company's Chief Executive Officer and the
former principal shareholder of Taylor.

    The $2.0 million shareholder note payable bears interest at 20.0%, of which
13.0% is due in cash, due monthly after December 1996, and 7.0% is payable in
Common Stock based on a value of $5.00 per share (27,999 shares annually). If
the note is retired within the first year of issuance, the shareholder is
entitled to the full 27,999 shares.
 
    As discussed in Note 2, as it is management's intent to retire this note
payable with a portion of the anticipated proceeds from the asset held for sale,
expected interest expense from this note payable (including the deferred
financing cost related to the share issuance) during the estimated period the
asset will be held for sale, was offset against the anticipated proceeds in
deriving the carrying value of the asset held for sale.

6. COMMITMENTS AND CONTINGENCIES
 
    The Company has an operating lease with a partnership owned by the principal
shareholder and a shareholder/officer. Monthly rental payments of $12,000 plus
property taxes, insurance and utilities are due through April 1997. In December
1996, the lease was renewed through April 2002, on similar terms.
 
   
    The Company leases various other office space and office equipment under
operating leases that expire in various years through 2000. Subsequent to March
31, 1996, the Company entered into an additional office lease which requires
monthly rental payments of $1,969 through October 1999. Rent expense for fiscal
1994, 1995 and 1996 was approximately $187,000, $164,000 and $243,000,
respectively; and $138,000 and $425,000 for the nine months ended December 31,
1995 and 1996, respectively. Included in the table below on a net basis is
sublease income of approximately $54,000 for fiscal 1997 and 1998 and $27,000
for fiscal 1999 for two office locations that were leased by Cincinnati.

    Certain officers and employees of the Company have employment contracts
through 2000.
 
    Under the terms of various agreements, the Company is obliged to pay
royalties on product sales at rates from 3.0% to 17.0%. The Company has made
certain advance payments in respect of future royalties. Prepaid royalties are
amortized to earnings based on actual sales realized over the term of the
applicable royalty agreement.
 
   
    To manage its foreign currency risk related to its purchases of inventory
from a Japanese vendor (see Note 11), the Company hedges firm inventory purchase
commitments by entering into forward contracts to purchase Japanese Yen. This
hedging minimizes the impact of foreign exchange rate movements on the Company's
operating results. Gains and losses on the hedge positions are deferred and
included as a component of the transaction when it is completed. At January 29,
1997, the Company had outstanding forward contracts for the purchase of Japanese
Yen through April 15, 1997 of approximately $3.2 million to hedge equivalent
outstanding commitments transacted in Yen.
    
 
    Following this offering, the holders of certain shares of Common Stock will
have certain rights to cause the Company to register those shares under the
Securities Act of 1933, as amended (the "Securities Act"). By separate
agreements, these registration rights apply to holders of 1,382,655 shares of
Common Stock of the Company, and the 767,112 shares issuable to the former
shareholders of Taylor upon the conversion of Taylor Class C Exchangeable common
stock (collectively, the "Rights Holders"). All of such registration rights
agreements provide that the Rights Holders' registration rights are subject to
certain notice requirements and to the condition that, in the case of any
piggyback registration rights, the underwriters of any offering have the right
to limit the number of shares included in such registration. The Company has
agreed to bear the expenses of all registrations under these registration rights
agreements, except for underwriting discounts, selling commissions and
underwriters' expense allowances, which are to be paid by the respective Rights
Holders.
 
    The Company is not involved in any material legal proceedings.
 
7. REDEEMABLE COMMON STOCK ISSUANCES
 
    During December 1993, the Company sold 1,204,653 shares of Common Stock for
$1.0 million. Included in the terms of the agreement related to this sale are
certain covenants, including a requirement

that the Company use its best efforts to effect a sale to an unrelated third
party of all or substantially all of its assets or complete an initial public
offering of its stock by December 16, 1998. The shareholder has the right to put
the shares to the Company at fair market value, as defined in the agreement, for
a two-year period in the event the Company is in violation of any of these
covenants. The Company was in compliance with these covenants at December 31,
1996. This put right automatically terminates upon the closing of a qualified
initial public offering.
    
 
   
    In connection with the acquisition of Cincinnati (see Note 2), the Company
issued 150,003 shares of Common Stock. Between January 29, 1998 and January 28,
2000, the shareholder has the right to put the shares to the Company at fair
value as defined in this agreement. This redemption right terminates upon the
closing of an initial public offering.
    
 
   
    Although management has not obtained an appraisal of the fair market value
of the Company, certain equity transactions have occurred upon which management
has based its estimate of the potential redemption value of the aforementioned
shares. The estimated redemption values per share for the above referenced
shares were $0.83/share, $1.00/share and $2.33/share at March 31, 1994, 1995 and
1996, respectively, and $9.00/share at December 31, 1996.
    
 
   
    During July 1994, the Company sold an aggregate of 250,002 shares of Common
Stock to Digital Electronics (see Note 11) and to a distributor of Digital
Electronics products in exchange for $250,000. The shareholders have the right
to put the shares at any time to the Company at the lesser of (a) the original
purchase price or (b) the net book value per share (on a fully diluted basis) as
reflected on the consolidated balance sheet of the Company for the fiscal
quarter most recently completed. Redeemable common stock of $250,000 which would
otherwise be classified as current liabilities has been classified as long-term
because the Company intends to refinance such borrowings on a long-term basis
with its committed long-term borrowing facilities which it has available. The
shareholders have agreed to terminate this right upon the closing of an initial
public offering. These shares are reflected at a redemption value of $250,000 on
the accompanying balance sheets.
    
 
    In connection with the acquisition of Taylor, a portion of the consideration
exchanged by the Company was 767,112 shares of Class C Exchangeable common stock
of Taylor to the former holders of the voting common stock of Taylor. This
common stock is convertible at the holders' option into 767,112 shares of the
Company's Common Stock. This Class C Exchangeable common stock has no rights in
the assets or earnings of Taylor, has no voting rights and does not have the
right to the dividends of the Taylor Class A common stock outstanding. As a
result, this stock is not considered minority interest in Taylor; rather the
stock is treated as a redeemable stock of the Company. The Class C common
shareholders have the right to put the shares to the Company for $6.0 million
for a period of 10 days in the event the Company has not completed an initial
public offering of the Company's Common Stock by September 19, 1997.
 
    The $6.0 million redemption amount is due quarterly over three years, with
interest at prime and is subordinated to the bank notes payable. This redeemable
stock has been recorded at $4.65 million, the present value of the redemption
price based on an approximate 15% discount rate and is being accreted to its
redemption value over the life of the security using the effective interest rate
method.

8. STOCK OPTION PLANS
 
   
    The Company has four fixed option plans which reserve shares of common stock
for issuance to management, employees, directors and advisors of the Company.
The Company has adopted the disclosure-only provisions of Statement of Financial
Accounting Standards No. 123, "Accounting for Stock-Based Compensation" ("SFAS
No. 123"). Accordingly, no compensation cost has been recognized for the stock
option plans. Consistent with the provisions of SFAS No. 123, had compensation
cost for the Company's four stock option plans been determined based on the fair
value at the grant date for awards during fiscal 1996 and the nine months ended
December 31, 1996, the Company's net loss and net loss per share available to
shareholders would have been reduced to the pro forma amounts indicated below:

    The fair value of each option grant is estimated on the date of grant using
the Black-Scholes option-pricing model with the following weighted average
assumptions for grants during fiscal 1996 and the nine months ended December 31,
1996: dividend yield of 0%; expected volatility of 60%; risk-free interest rate
of 6%; and expected lives of 3 years.
    
 
    (A) 1993 STOCK OPTION PLAN
 
    The Company's 1993 Stock Option Plan (the "1993 Plan") provides for the
grant of common stock options.
 
    Under the 1993 Plan, incentive stock options ("ISOs") may be granted to any
officer or employee of the Company. Nonqualified stock options may be granted to
any officer, employee, consultant, director or other agent of the Company. In
the case of ISOs, the exercise price paid shall be at least 100% (110% in
certain cases) of the fair market value of the Common Stock on the date of
grant. Options become exerciseable generally over three years or as determined
by the Board. Certain acceleration provisions exist related to a change in
control of the Company or an initial public offering of the Company's Common
Stock.

    In December 1996, the Company adopted the 1996 Non-Employees Directors'

                                AUDITORS' REPORT
 
To the Directors of
Taylor Industrial Software Inc.
 
    We have audited the consolidated balance sheets of Taylor Industrial
Software Inc. as at March 31, 1995 and 1996 and the consolidated statements of
operations and retained earnings and changes in financial position for each of
the three years in the period ended March 31, 1996. 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 an audit to obtain
reasonable assurance 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.
 
    In our opinion, these consolidated financial statements present fairly, in
all material respects, the financial position of the company as at March 31,
1995 and 1996 and the results of its operations and the changes in its financial
position for each of the three years in the period ended March 31, 1996 in
accordance with Canadian generally accepted accounting principles.

                   NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
                                 MARCH 31, 1996
              (STATED IN CANADIAN DOLLARS, UNLESS OTHERWISE NOTED)
 
1. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES
 
    (A) BASIS OF PRESENTATION
 
    These financial statements have been prepared in Canadian dollars (the
company's functional currency) and in accordance with the accounting principles
generally accepted in Canada. These principles conform, in all material
respects, with accounting principles generally accepted in the United States,
except as disclosed in Note 13.
 
    The consolidated financial statements include the accounts of the company
and its wholly-owned subsidiary companies, Taylor Industrial Software (USA) Inc.
and Taylor Industrial Software (UK) Limited. All significant intercompany
transactions have been eliminated.
 
    (B) USE OF ESTIMATES
 
    The preparation of the 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 revenues and expenses during the period reported. Actual results
could differ from those estimates.
 
    (C) REVENUE RECOGNITION
 
    The company develops, licences and maintains productivity-enhancing
management and control software for manufacturing industries. Licence revenue
also includes revenue from the sale of certain software manufactured by third
parties. The company also provides training, consulting and post-contract
customer support for its products.
 
    Licence revenue is recognized on shipment of the product. Revenues from
training and consulting are recognized at the time the service is performed.
Revenue from post-contract customer support is recognized ratably over the
period of the post-contract arrangement.
 
    (D) RESEARCH AND DEVELOPMENT
 
    All research and development costs are expensed as incurred.
 
    (E) INVENTORY
 
    Inventory is recorded at the lower of average cost and net realizable value.

    (F) CAPITAL ASSETS
 
    Capital assets are recorded at cost, net of investment tax credits, and are
amortized over the estimated useful lives of the capital assets using the
following rates and bases:
 
<TABLE>
<S>                                    <C>
Office furniture and equipment         20% declining balance
Automotive equipment                   30% declining balance
Computer equipment                     33% straight-line
Computer software                      33% straight-line
Development equipment                  25% to 33% straight-line
Technology software                    25% straight-line
Leasehold improvements                 10% straight-line
</TABLE>
 
    Development equipment consists primarily of industrial and computer
equipment which is used in the software development process. Technology software
consists primarily of licences for the use of third party software which has
alternative uses.
 
    (G) INCOME TAXES
 
    The company records items for income tax purposes in amounts which differ
from that reflected in the financial statements. The tax effect of these
differences are reflected in the financial statements as deferred income taxes.
 
    (H) INVESTMENT TAX CREDITS
 
    The company is entitled to scientific research and experimental development
("SRED") investment tax credits granted by the Canadian federal government. SRED
tax credits are received on qualified Canadian SRED expenditures (100%
refundable) and capital purchases (40% refundable, 60% non-refundable). As a
Canadian Controlled Private Corporation ("CCPC"), SRED tax credits are earned at
the rate of 35% on the first $2 million of qualified expenditures and 20% on
amounts in excess of $2 million. SRED tax credits reduce federal income taxes
currently payable and, to the extent these credits exceed income taxes currently
payable, may be received in cash from the federal government, subject to various
limitations which reduce the refundable amount relating to capital SRED
expenditures to 40%. The remaining 60% non-refundable portion of capital SRED
expenditures can be carried forward and applied to reduce federal taxes payable
in future years (NOTE 8).
 
    The entitlement to SRED tax credits will change if the company loses its
CCPC status. CCPC status is lost when a company is public as defined in the
Income Tax Act (Canada), or is controlled by non-Canadian residents or a public
corporation. For federal tax purposes, non-CCPC corporations are entitled to
SRED tax credits at a rate of 20% of qualified expenditures, with no refundable
component available.
 
    As a result of the purchase of the company on September 26, 1996 by Total
Control Products, Inc., a U.S. company (SEE NOTE 11), any subsequent SRED tax
credits will be earned at a rate of 20% of qualified expenditures, with no
refundable component available. This change in status has no effect on
investment tax credits earned for fiscal periods prior to September 26, 1996.

                                 MARCH 31, 1996
        (STATED IN CANADIAN DOLLARS, UNLESS OTHERWISE NOTED) (CONTINUED)
 
1. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (CONTINUED)
    SRED tax credits are accounted for as a reduction of the related
expenditures. The refundable portion of SRED tax credits is recorded in the year
in which they are earned. The non-refundable portion of SRED tax credits is
recorded at such time as the company has reasonable assurance that the credits
will be realized.
 
    (I) TRANSLATION OF FOREIGN CURRENCIES
 
    The company's foreign operations' financial statements are translated from
the foreign entity currency using the method for integrated foreign operations;
monetary items are translated at the rates prevailing at the balance sheet date
and non-monetary items are translated at historic rates. Revenues and expenses
are translated at weighted-average rates throughout the year except for
amortization which is translated at the same rates as the related capital asset.
Foreign exchange gains and losses are included in income.
 
2. REFUNDABLE SRED INVESTMENT TAX CREDITS
 
    The company has recorded anticipated refunds of federal SRED investment tax
credits in the amount of $385,664 resulting from scientific research and
experimental development activities. This amount consists of 1996 credits
totaling $95,091, 1995 credits totaling $220,355 and the unpaid balance of 1994
credits totaling $70,218.

    The "First Preferred" shares are redeemable and retractable at $11.03 per
share. The "First Preferred" shares are entitled to an annual cumulative
dividend at the rate of 4/5 of the bank prime lending rate on April 1 of each
year.
 
    Cumulative undeclared dividends in the amount of $218,624 (1995 - $85,400)
have not been recorded. The dividends will be recorded when declared.
 
11. SUBSEQUENT EVENTS
 
    As at April 30, 1996, the company amended its issued and outstanding Class
"A" common shares from 100 to 1,000,000.
 
    In addition, on April 30, 1996 the company established an employee share
option plan whereby eligible employees are entitled to acquire common shares of
the company under certain conditions and obligations specified within the plan
at "market value". Market value is set by the Board in June of each year or at
such other time as the Board deems appropriate. As at September 26, 1996,
options to acquire 20,002 shares had been granted to certain employees.
 
   
    Effective September 26, 1996, the company repurchased all of the outstanding
share options for an amount of $275,155. On this date, all of the issued and
outstanding Class "A" common shares and "First Preferred" shares were purchased
by Total Control Products, Inc., a U.S. company. Under the terms of the stock
purchase agreement, the former shareholders of the company are entitled to
receive certain contingent compensation pursuant to an earn-out formula. Under
such formula, if the actual consolidated revenues of the company ("Net
Revenues") between November 1, 1996 and September 30, 1997 exceed $8.0 million,
the company will pay the former shareholders an aggregate amount equal to $1.0
million, and to the extent that Net Revenues during such period exceed $9.2
million, the company will pay to the former shareholders an aggregate amount,
not to exceed $3.0 million, equal to 50% of such excess. In addition, for the
period between November 1, 1997 and September 30, 1998, if Net Revenues exceed
$8.0 million, the company will pay to the former shareholders an aggregate
amount equal to $1.0 million and to the extent that Net Revenues during such
period exceed $10.6 million, the Company will pay to the former shareholders an
amount, not to exceed $3.0 million, equal to 50.0% of such excess.
    
 
    As a result of the purchase by Total Control Products, Inc., the company
ceased to be a Canadian Controlled Private Corporation ("CCPC") on September 26,
1996. Because of this, from September 26, 1996 forward, the company's effective
income tax rate will increase to 43.5% from 20%, investment tax credits on
qualifying Canadian SRED expenditures will be reduced from 35% to 20% and there
will be no refundable portion of investment tax credits. In addition, the
repayment terms on the loans from Western Economic Diversification have been
accelerated such that the loans will be repaid by March 31, 1997.
 
    In connection with the purchase of the company by Total Control Products,
Inc., the company entered into a two-year consulting agreement with Digital
Electronics Corporation whereby Digital Electronics Corporation has agreed to
provide certain product development and marketing consulting services to the
company in exchange for compensation of U.S. $200,000 per year. This agreement
terminates in November 1998.

        (STATED IN CANADIAN DOLLARS, UNLESS OTHERWISE NOTED) (CONTINUED)
 
12. CHANGE IN ACCOUNTING POLICY
 
    On September 26, 1996, the company retroactively changed its revenue
recognition policy to recognize the customer support portion of new licence
revenue ratably over the period of the post-contract arrangement. Previously,
revenue was recognized on shipment of the licence and the costs associated with
providing the post-contract customer support were accrued. Revenue was reduced
by $95,728 in 1994, and $31,336 in 1995 and was increased by $13,532 in 1996 to
reflect this change. This change in policy, net of related income taxes, had the
effect of reducing opening retained earnings in 1994 by $224,454, decreasing net
income in 1994 by $57,963 and in 1995 by $18,336, and increasing net income in
1996 by $8,148. The March 31, 1994, 1995 and 1996 opening retained earnings and
the financial statements for each of these periods have been restated to reflect
this change.
 
13. UNITED STATES ACCOUNTING PRINCIPLES
 
   
    The financial statements of the company have been prepared in accordance
with accounting principles generally accepted in Canada ("Canadian GAAP"). These
principles conform, in all material respects, with accounting principles
generally accepted in the United States ("U.S. GAAP"), except for the items
discussed in the tables below. Under Canadian GAAP, the change in accounting
policy referred to in note 12 was a change from one acceptable method of
accounting for post-contract services to a more preferable method. The previous
accounting method used for Canadian GAAP would not have been in accordance with
U.S. GAAP. Financial statements for periods prior to the change prepared in
accordance with U.S. GAAP would have required a restatement. As the financial
statements prepared in accordance with Canadian GAAP were retroactively restated
due to the change in accounting principles under Canadian GAAP, this difference
would not have an effect on net income or shareholders' equity for the periods
presented.

(1) Under Canadian GAAP, the redeemable retractable "First Preferred" shares are
    included in shareholders' equity. Under U.S. GAAP, these shares are
    classified as mandatorily redeemable shares outside of shareholders' equity
    and are reported at full redemption amount. For years commencing on or after
    January 1, 1996, Canadian GAAP would require the Company to present these
    shares as liabilities measured at the redemption amount.
 
(2) Under Canadian GAAP, cumulative dividends on the redeemable retractable
    "First Preferred" shares are not recorded until declared. Under U.S. GAAP,
    cumulative dividends on mandatorily redeemable shares are accrued, even if
    not declared, when they are payable at a future date.
 
(3) Under Canadian GAAP, cash outflows related to non-current assets may be
    classified as investing activities. Under U.S. GAAP, cash outflows related
    to investing activities are limited to disbursements

    for loans, payments to acquire debt instruments or equity instruments of
    other enterprises, or payments to acquire capital assets. Cash outflows not
    meeting these criteria are classified as operating activities.
 
(4) Under Canadian GAAP, the statement of changes in financial position may be
    based on cash net of bank advances and operating bank loans. Under U.S.
    GAAP, the statement of cash flows is to be based on cash only, with
    increases and decreases in bank advances and operating bank loans being
    shown as financing activities.
 
    The net change in non-cash working capital items is made up as follows:

(1) Under Canadian GAAP, the statement of changes in financial position may be
    based on cash net of bank advances and operating bank loans. Under U.S.
    GAAP, the statement of cash flows is to be based on cash only, with
    increases and decreases in bank advances and operating loans being shown as
    financing activities.
 
    The functional currency of Taylor is the Canadian dollar. As such, these
balances have not been translated into U.S. dollars.
 
    Additionally, the accompanying unaudited condensed statements have been
prepared in accordance with generally accepted accounting practices for interim
periods. Accordingly, they do not include all of the information and footnotes
required by generally accepted accounting principles for complete financial
statements. It is suggested that these condensed financial statements be read in
conjunction with the financial statements and notes thereto included elsewhere
in this prospectus.

1. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES
 
    (A) GENERAL
 
    Cincinnati Dynacomp, Inc. (the "Corporation"), an Ohio corporation,
develops, manufactures and markets industrial automation tools. Its products
consist primarily of operator interfaces for programmable logic controllers.
 
    (B) PROPERTY AND EQUIPMENT
 
    Expenditures for repairs, maintenance and minor renewals are expensed as
incurred. Property and equipment are reported at cost and depreciated primarily
using the straight-line method over their estimated useful lives as follows:
 
<TABLE>
<S>                                                                        <C>
Machinery and equipment..................................................    5 years
Furniture and fixtures...................................................    5 years
Exhibits and demonstrators...............................................  3-5 years
Computer equipment.......................................................  3-4 years
</TABLE>
 
    Leasehold improvements are depreciated over the life of the underlying asset
or the term of the lease, whichever is shorter.
 
    (C) CAPITALIZED SOFTWARE COSTS
 
    Software development costs incurred internally to create computer software
products are charged to research and development expense until technological
feasibility has been established for the product. Thereafter, all software
production costs are capitalized and subsequently reported at the lower of
amortized cost or net realizable value. Capitalized costs are amortized based on
current and projected future revenue for each product with an annual minimum
amount equal to straight-line amortization over three years. Amortization
expense was $182,953 and $107,066 in 1994 and 1995, respectively.
 
    (D) DEVELOPMENT COSTS
 
    Development costs are capitalized costs relating to tailoring a product for
a specific customer. These costs are amortized over the actual units sold based
on the number of units expected to be sold.
 
    (E) GOODWILL
 
    The excess of the acquisition cost over the net assets of the Dynacomp
merger discussed below is being amortized using the straight-line method over 15
years. Amortization expense related to goodwill was $3,656 and $21,221, for the
years ended March 31, 1994 and 1995, respectively.
 
    (F) INCOME TAXES
 
    The Corporation adopted Statement of Financial Accounting Standards ("SFAS")
No. 109 effective April 1, 1993. Previously, the Corporation accounted for
income taxes using the deferred method set forth in Accounting Principles Board
Opinion No. 11. The cumulative effect resulting from the adoption of SFAS No.
109 was the recognition of a net deferred tax asset totaling $235,000 at April
1, 1993. However, because of recent losses and considering the amount of the
taxable income which would be generated in future years, the Corporation
provided a valuation allowance of $235,000 offsetting the effect of adopting
SFAS No. 109 on the financial statements at April 1, 1993.

    Revenues are recognized when the product is shipped.
 
    (H) RESEARCH AND DEVELOPMENT EXPENSES
 
    Engineering research and development expenses related to present and future
products are charged to expense as incurred. Total expenditures on research and
development were $117,406 and $181,946 in 1994 and 1995, respectively, and are
included in selling, general and administrative expenses.

substantially all employees. Contributions to the profit-sharing plan are made
at the discretion of the Board of Directors. No contributions were declared in

    (J) CONCENTRATION OF CREDIT RISK
 
    The Corporation designs and manufactures several lines of electronic
equipment and related software products for a variety of industries which are
located throughout the United States and overseas. The Corporation performs
periodic credit evaluations of its customers' financial condition and generally

    (K) MERGER
 
    Cincinnati Electrosystems, Inc. ("CEI") entered into a merger agreement with
Logan Blake Industrial Corporation (d/b/a Dynacomp) that provided for Dynacomp
to be merged into CEI which was renamed Cincinnati Dynacomp, Inc. The former
stockholders of Dynacomp were to receive shares of the Corporation in the
merger.
 
    The operations were merged effective November 1, 1993 and are included in
the accompanying financial statement from that date. However, prior to the
shares in the Corporation being issued, the CEI stockholders asserted that the
financial condition of Dynacomp was not as represented prior to the merger and
refused to issue shares to the Dynacomp stockholders without an adjustment. One
of the Dynacomp stockholders agreed not to take any shares and, in August 1994,
the other settled for a $75,000 payment and forgiveness of a $20,000 obligation
to the Corporation in lieu of receiving shares of the Corporation. The
accompanying financial statements reflect the effects of the August 1994
settlement.
 
    The merger has been accounted for as a purchase. Financial information
necessary to disclose pro forma results of operations for the years ended March
31, 1993 and 1994 is not available.

               NOTES TO UNAUDITED CONDENSED FINANCIAL STATEMENTS
 
NOTE 1. BASIS OF PRESENTATION
 
    The accompanying unaudited condensed statements have been prepared in
accordance with generally accepted accounting practices for interim periods.
Accordingly, they do not include all of the information and footnotes required
by generally accepted accounting principles for complete financial statements.
It is suggested that these condensed financial statements be read in conjunction
with the financial statements and notes thereto included elsewhere in this
prospectus.
 
    In the opinion of management, the unaudited interim financial statements
reflect all adjustments, consisting of normal recurring adjustments, necessary
to present fairly the Company's consolidated results of operations and cash
flows for all periods presented.

                        UNAUDITED PRO FORMA AS ADJUSTED
                  CONDENSED CONSOLIDATED FINANCIAL STATEMENTS
 
    The following Unaudited Pro Forma As Adjusted Condensed Consolidated
Statements of Operations are based on the historical Consolidated Financial
Statements of Total Control Products, Inc. ("Total Control") included elsewhere
in this Prospectus, adjusted to give effect to (i) the acquisition by Total
Control of Cincinnati Dynacomp, Inc. ("Cincinnati") and the acquisition by Total
Control of a controlling interest in Taylor Industrial Software Inc. ("Taylor")
and (ii) the sale by Total Control of 1,650,000 shares of Common Stock in the
offering to which this Prospectus relates and the application of the estimated
net proceeds therefrom to repay certain indebtedness as set forth under "Use of
Proceeds" and (a) the elimination upon the closing of the offering of certain
redemption rights of Common Stock and (b) the automatic conversion of
convertible debentures into shares of Common Stock upon completion of the
offering. The Unaudited Pro Forma As Adjusted Condensed Consolidated Financial
Statements assume these events occurred on April 1, 1995.
 
   
    The Unaudited Pro Forma As Adjusted Condensed Consolidated Statement of
Operations for the year ended March 31, 1996 reflects the audited statement of
operations of Total Control and Taylor for the year ended March 31, 1996, and
the unaudited statement of operations of Cincinnati for the ten months ended
January 29, 1996 (the date of its acquisition), on a historical basis. The
Unaudited Pro Forma As Adjusted Condensed Consolidated Statement of Operations
for the nine months ended December 31, 1996 reflects the unaudited income
statement of Total Control for the nine months ended December 31, 1996, and the
unaudited income statements of Taylor for the six months ended September 26,
1996 (the date of its acquisition), on a historical basis.
    
 
    The historical statements of operations of Taylor located elsewhere in this
Prospectus were prepared in accordance with accounting principles generally
accepted in Canada. These principles conform, in all material respects, with
accounting principles generally accepted in the United States, except for those
items disclosed in the notes to the financial statements of Taylor, none of
which impacted the historical statements of operations.
 
    For the purpose of the preparation of the Unaudited Pro Forma As Adjusted
Condensed Consolidated Statements of Operations only, the historical statements
of operations for Taylor described above were translated from Canadian dollars
(Taylor's functional currency) to U.S. dollars at the approximate average
exchange rate for the respective periods.
 
   
    The pro forma financial information is a presentation of historical results
with accounting and other adjustments. The pro forma financial information does
not reflect the effects of any of the anticipated changes to be made by the
Company in the operations from the historical operations.
    
 
    The pro forma statements presented are provided for informational purposes
only and should not be construed to be indicative of the Company's results of
operations had the transactions been consummated on the date assumed and do not
project the Company's results of operations for any future period.
 
    The Unaudited Pro Forma As Adjusted Condensed Consolidated Statements and
accompanying notes should be read in conjunction with the financial statements
and the financial information pertaining to Total Control, Cincinnati and Taylor
included elsewhere in this Prospectus.

                        UNAUDITED PRO FORMA AS ADJUSTED
                  CONDENSED CONSOLIDATED FINANCIAL STATEMENTS
 
The following notes identify the pro forma adjustments made to the historical
amounts in the pro forma unaudited condensed consolidated financial statements:
 
   
        (a) Represents the elimination of the revenues and related expenses of
    Taylor's labor scheduling software product line, which is currently being
    held for sale by the Company, including operating expenses of $973,000 and
    $608,000 for the year ended March 31, 1996 and the nine months ended
    December 31, 1996, respectively.
    
 
   
        (b) Represents an increase in depreciation and amortization expense
    based on the useful lives assigned in connection with the acquisition for
    (i) the net decrease in depreciation expense of $14,000 related to the net
    decrease in the depreciable basis of certain assets for the year ended March
    31, 1996 and an increase in depreciation expense of $16,000 for the increase
    in the depreciable basis of certain assets for the nine months ended
    December 31, 1996, and (ii) an increase in amortization expense for the year
    ended March 31, 1996 and the nine months ended December 31, 1996 of
    approximately $451,000 and $179,000, respectively, related to the
    amortization of goodwill related to the acquisitions of Cincinnati and
    Taylor. These pro forma adjustments do not give effect to the impact on
    goodwill amortization, if any, related to any future contingent earnout
    payments for these acquisitions as none has been earned to date.
    
 
   
        (c) Represents (i) the elimination of the non-recurring charge for
    purchased research and development of $4,893,000 recorded by the Company in
    the Total Control statement of operations for the nine months ended December
    31, 1996, which was directly attributable to the Taylor acquisition and (ii)
    a decrease in operating expenses to eliminate $202,000 of compensation
    expense related to the purchase by Taylor of outstanding employee stock
    option arrangements, which is included in the results of Taylor for the six
    months ended September 26, 1996 results of Taylor, in connection with the
    terms of the acquisition of Taylor. Except for $193,000, these non-recurring
    items were recorded on the Taylor subsidiary financial statements, and
    accordingly, 39% of this amount has been included in the pro forma
    adjustment made to minority interest described in Note (f) below.
    
 
   
        (d) Represents an increase in interest expense associated with the debt
    incurred to finance the acquisition of Cincinnati for the year ended March
    31, 1996. Additionally, interest expense on debt incurred in connection with
    the acquisition of Taylor for the year ended March 31, 1996 and the nine
    months ended December 31, 1996 of approximately $700,000 and $350,000,
    respectively, was offset by a corresponding adjustment in the same amount to
    reflect the anticipated repayment of the acquisition debt with the proceeds
    anticipated to be received from the sale of Taylor's labor scheduling
    software product line.
    
 
   
        (e) Represents the income tax effects of the pro forma adjustments at an
    assumed effective income tax rate of 40% for the pro forma adjustments,
    except for pro forma adjustments related to Taylor, for which an effective
    rate of 43% was assumed. The amortization expense and compensation expense
    described above in Note (b) (ii) and Note (c) (ii) were not tax effected.
    Additionally, the tax benefit of $112,000 for the loss incurred by
    Cincinnati for the ten months ended January 29, 1996 was recorded. Finally,
    adjustments of $93,000 and $110,000 were recorded to increase the tax
    benefit recorded in the Taylor statements of operations for the year ended
    March 31, 1996 and the nine months ended December 31, 1996, respectively, as
    a result of the change in tax rate from 20% to 43% applied to the taxable
    income of Taylor due to the change in ownership.

                        UNAUDITED PRO FORMA AS ADJUSTED
            CONDENSED CONSOLIDATED FINANCIAL STATEMENTS (CONTINUED)
    
 
   
        (f) Represents the minority interest of 39% in the pro forma loss of
    Taylor Industrial Software Inc.
    
 
   
        (g) Represents the impact of the offering. Interest expense is decreased
    as a result of applying the net proceeds of the offering to repay certain
    indebtedness as described under "Use of Proceeds." Provision for income
    taxes is increased for the decrease in interest expense using the effective
    tax rates as described in Note (e). Minority interest is increased by the
    39% share of the decrease in the pro forma loss of Taylor resulting from
    these adjustments. In addition, accretion to redemption value of common
    stock is eliminated to reflect the automatic termination of the redemption
    rights upon the closing of the offering.
    
 
   
        (h) Represents the increase in weighted average shares outstanding for
    (i) the issuance of 1,650,000 shares of common stock to be sold by the
    Company in the offering contemplated by this Prospectus, (ii) the issuance
    of 407,239 shares and 339,366 shares of Common Stock issuable for the year
    ended March 31, 1996 and the nine months ended December 31, 1996,
    respectively, upon the automatic conversion of convertible debentures upon
    the closing of the offering and, in the case of the year ended March 31,
    1996, the conversion of a portion of the debenture in June 1996 and (iii)
    the dilutive effect of outstanding common stock options of 129,273 shares
    calculated using the treasury stock method.

ITEM 14.  INDEMNIFICATION OF DIRECTORS AND OFFICERS.
 
    The Company has adopted provisions in its Articles of Incorporation that, to
the fullest extent provided under Illinois law, limit the liability of its
directors and officers for monetary damages arising from a breach of their
fiduciary duties as directors or officers. Such limitation of liability does not
affect the availability of equitable remedies such as injunctive relief or
rescission, nor does it limit liability for (i) any breach of the director's
duty of loyalty to the Company or its shareholders, (ii) acts or omissions not
in good faith or which involve intentional misconduct or a knowing violation of
law, (iii) a transaction from which a director derives an improper personal
benefit or (iv) an unlawful distribution to the Company's shareholders. The
Company's By-laws provide that the Company shall indemnify its directors to the
fullest extent permitted by Illinois law, including circumstances in which
indemnification is otherwise discretionary to the Company under Illinois law,
and permit the Company in its discretion to similarly indemnify its officers,
employees and agents.
 
    The form of Underwriting Agreement filed as Exhibit 1.1 provides for the
indemnification of the Company, its controlling persons, its directors and its
officers by the Underwriters against certain liabilities, including liabilities
under the Securities Act.

ITEM 17.  UNDERTAKINGS
 
    The undersigned Registrant hereby undertakes to provide to the Underwriters
at the closing specified in the Underwriting Agreement certificates in such
denominations and registered in such names as required by the Underwriters to
permit prompt delivery to each purchaser.
 
    Insofar as indemnification for liabilities arising under the Securities Act
of 1933 may be permitted to directors, officers and controlling persons of the
Registrant pursuant to the foregoing provisions (see response to Item 14 above),
or otherwise, the Registrant has been advised that in the opinion of the
Securities and Exchange Commission such indemnification is against public policy
as expressed in the Act and is, therefore, unenforceable. In the event that a
claim for indemnification against such liabilities (other than the payment by
the Registrant of expenses incurred or paid by a director, officer or
controlling person of the Registrant in the successful defense of any action,
suit or proceeding) is asserted by such director, officer or controlling person
in connection with the securities being registered, the Registrant will, unless
in the opinion of its counsel the matter has been settled by controlling
precedent, submit to a court of appropriate jurisdiction the question of whether
such indemnification by it is against public policy as expressed in the Act and
will be governed by the final adjudication of such issue.
 
    The undersigned Registrant hereby undertakes that:
 
        (1) For purposes of determining any liability under the Securities Act
    of 1933, the information omitted from the form of prospectus filed as part
    of this registration statement in reliance upon Rule 430A and contained in a
    form of prospectus filed by the registrant pursuant to Rule 424(b)(1) or (4)
    or 497(h) under the Securities Act shall be deemed to be part of this
    registration statement as of the time it was declared effective.
 
        (2) For the purpose of determining any liability under the Securities
    Act of 1933, each post-effective amendment that contains a form of
    prospectus shall be deemed to be a new registration statement relating to
    the securities offered therein, and the offering of such securities at that
    time shall be deemed to be the initial bona fide offering thereof.

                          TOTAL CONTROL PRODUCTS, INC.

                AMENDED AND RESTATED ARTICLES OF INCORPORATION

     FOURTH.   The Corporation is authorized to issue a total of 23,500,000
shares of stock, consisting of 22,500,000 shares of common stock, no par value
per share (the "Common Shares") and 1,000,000 shares of preferred stock, no par

the holders of the Preferred Shares shall not be entitled to exercise cumulative
voting or preemptive rights.  There are 1,540,692 Common Shares issued with 
paid-in capital of $1,686,162.

                                   Section A

                                 Common Shares

     1.   VOTING RIGHTS. Except as otherwise provided by law, each Common Share

<PAGE>

     2.   DIVIDENDS AND DISTRIBUTIONS.  Subject to the express terms of the
Preferred Shares outstanding from time to time, the holders of the Common Shares
shall be entitled to receive such dividends and distributions as may from time

                                   Section B

                                Preferred Shares

     Subject to the terms contained in any designation of a series of 
Preferred Shares, the Board of Directors of the Corporation is expressly 
authorized, at any time and from time to time, to issue Preferred Shares in 
one or more series, and for such consideration as the Board of Directors of 
the Corporation may determine, and to fix, by resolution or resolutions, the 
following provisions for shares of any class or classes of Preferred Shares 
or any series of any class of Preferred Shares.

     1.   the designation of such class or series, the number of shares to 
constitute such class or series which may be increased or decreased (but not 
below the number of shares of that class or series then outstanding) by 
resolution of the Board of Directors of the Corporation, and the stated value 
thereof if different from the par value thereof;

     2.   whether the shares of such class or series shall have voting 
rights, in addition to any voting rights provided by law, and if so, the 
terms of such voting rights;

     3.   the dividends, if any, payable on such class or series, whether any 
such dividends shall be cumulative, and if so, from what dates, the 
conditions and dates upon which such 

                                       2

<PAGE>

dividends shall be payable, and the preference or relation such dividends 
shall bear to the dividends payable on any shares of stock of any class or 
any other series of the same class;

     4.   whether the shares of such class or series shall be subject to 
redemption by the Corporation, and if so, prices and other conditions of such 
redemption;

     5.   the amount or amounts payable upon shares of such series upon, and 
the rights of the holders of such class or series in, the voluntary or 
involuntary liquidation, dissolution or winding up, or upon any distribution 
of the assets, of the Corporation; 

     6.   whether the shares of such class or series shall be subject to the 
operation of a retirement or sinking fund and if so, the extent and manner in 
which any such retirement or sinking fund shall be applied to the purchase or 
redemption of the shares of such class or series for retirement or other 
corporate purposes and the terms and provisions relative to the operation 
thereof;

     7.   whether the shares of such class or series shall be convertible 
into, or exchangeable for, shares of stock of any class or any other series 
of the same class or any other securities and if so, the price or prices or 
the rate or rates of conversion or exchange and the method, if any, of 
adjusting the same, and any other terms and conditions of conversion or 
exchange;

     8.   the limitations and restrictions, if any, to be effective while any 
shares of such class or series are outstanding upon the payment of dividends 
or the making of other distributions on, and upon purchase, redemption or 
other acquisition by the Corporation of the Common Shares or shares or stock 
of any class or any other series of the same class;

                                       3

<PAGE>

     9.   the conditions or restrictions, if any, upon the creation of 
indebtedness of the Corporation or upon the issue of any additional stock, 
including additional shares of such class or series or of any other series of 
the same class or of any other class;

     10.  the ranking (be it PARI PASSU, junior or senior) of each class or 
series vis-a-vis any other class or series of any class of Preferred Shares 
as to the payment of dividends, the distribution of assets and all other 
matters; and

     11.  any other powers, preferences and other rights and any 
qualifications, limitations and restrictions thereof, insofar as they are not 
inconsistent with the provisions of this Amended and Restated Articles of 
Incorporation, to the full extent permitted in accordance with the laws of 
the State of Illinois.

     The powers, preferences and other rights of each class or series of 
Preferred Shares and the qualifications, limitations or restrictions thereof, 
if any, may differ from those of any and all other series at any time 
outstanding.  The Preferrerd Shares will have preference as to assets of the 
Corporation over the Common Shares upon the voluntary or involuntary 
liquidation of the Corporation.

     FIFTH.    The members of the governing board shall be called directors of
the Corporation.  The number of directors of the Corporation shall be six (6). 
The directors shall be divided into three (3) classes designated as Class I,
Class II and Class III, respectively.  Each class shall consist, as nearly as
may be possible, of one-third of the total number of directors constituting the
entire board of directors. Effective upon the closing of an initial public
offering of the Corporation under the Securities Act of 1933, as amended, the 
Corporation shall designate the slate of directors to be elected by the 
shareholders as Class I, Class II and Class III directors.  The initial term 
of office of the Class I directors shall expire at the annual meeting of the 
shareholders held in

                                       4

<PAGE>

the year 1998.  The initial term of office of the Class II directors shall 
expire at the annual meeting of shareholders held in the year 1999.  The 
initial term of office of the Class III directors shall expire at the annual 
meeting of shareholders held in the year 2000.  At each annual meeting of the 
shareholders after the annual meeting held in the year 1997, successors to 
the class of directors whose term expires at the annual meeting shall be 
elected for a three (3) year term.  If the number of directors is changed, 
any increase or decrease shall be apportioned among the classes so as to 
maintain the number of directors in each class as nearly as possible, but in 
no case shall a decrease in the number of directors shorten the term of any 
incumbent director.  A director shall hold office until the annual meeting 
for the year in which his term expires and until his successor shall be 
elected and qualified, subject, however, to prior death, resignation, 
retirement, disqualification or removal from office.  The annual meeting of 
shareholders shall be held each year on a date and at a time designated by 
the Board of Directors of the Corporation.

     Subject to the rights, if any, of holders of any series of Preferred 
Shares then outstanding, any vacancy on the Board of Directors that results 
from an increase in the number of directors or by reason of the vacancy 
following the annual meeting of the shareholders held in the year 1997 may be 
filled by a majority of the Board of Directors then in office, provided that 
a quorum is present, and any other vacancy occurring in the Board of 
Directors may be filled by a majority of the directors then in office, even 
if less than a quorum.  Any directors elected to fill a vacancy resulting 
from an increase in such class shall hold office for a term that shall 
coincide with the remaining term of that class.  Any director elected to fill 
a vacancy not resulting from an increase in the number of directors shall 
have the same remaining term as that of his predecessor.

                                       5

<PAGE>

     SIXTH. Special meetings of the shareholders, for any purpose or purposes 
(except to the extent otherwise provided by law or this Amended and Restated 
Articles of Incorporation), may only be called by the Chairman of the Board, 
the President, any three (3) directors then in office or by the holders of 
not less than one-fifth of all outstanding shares entitled to vote on the 
matter for which the meeting is called.  Such request shall state the purpose 
or purposes of the proposed meeting.

     SEVENTH.  In furtherance and not in limitation of the powers conferred 
by the laws of Illinois, the Board of Directors is expressly authorized and 
empowered to make, alter, amend and repeal the By-laws of the Corporation in 
any respect not inconsistent with the laws of the State of Illinois or with 
this Amended and Restated Articles of Incorporation.

     EIGHTH.   The books of the Corporation may be kept at such place within or
without the State of Illinois as the By-laws of the Corporation may provide 
or as may be designated from time to time by the Board of Directors of the 
Corporation.

                                       6

<PAGE>

     NINTH.  The capital stock, after the amount of the subscription price 
has been paid in full, shall not be subject to assessment to pay the debts of 
the Corporation.

     TENTH.  The Corporation is to have perpetual existence. 

     ELEVENTH.  No director or officer of the Corporation shall be personally 
liable to the Corporation or its Shareholders for monetary damages for breach 
of fiduciary duty as a director or officer, except for liability (a) for any 
breach of the director's duty of loyalty to the Corporation or its 
Shareholders; (b) for acts or omissions not in good faith or which involve 
intentional misconduct or a knowing violation of law; (c) under Section 8.65 
of the Illinois Business Corporation Act, as the same exists or hereafter may 
be amended; or (d) for any transaction from which the director derived an 
improper personal benefit.

     If the Illinois Business Corporation Act hereafter is amended to 
authorize the further elimination or limitation of the liability of 
directors, then the liability of the Corporation's directors 

                                       7

<PAGE>

shall be eliminated or limited to the full extent authorized by the Illinois 
Business Corporation Act, as so amended.

     Any repeal or modification of this Article by the shareholders of the 
Corporation shall be prospective only, and shall not adversely affect any 
right or protection of a director or officer of the Corporation existing at 
the time of such repeal or modification.

     TWELFTH 1.  To the extent not prohibited by law, the Corporation 
shall indemnify any person who was or is a party, or is threatened to be made 
a party to any threatened, pending or completed action, suit or proceeding, 
whether civil, criminal, administrative or investigative (other than an 
action by or in the right of the Corporation) by reason of the fact that he 
or she is or was a director of the Corporation, or who is or was serving at 
the request of the Corporation as a director of another Corporation, 
partnership, joint venture, trust or other enterprise, against expenses 
(including attorneys' fees), judgments, fines and amounts paid in settlement 
actually and reasonably incurred by such person in connection with such 
action, suit or proceeding, if such person acted in good faith and in a 
manner he or she reasonably believed to be in, or not opposed to the best 
interests of the Corporation, and, with respect to any criminal action or 
proceeding, had no reasonable cause to believe his conduct was unlawful.  The 
termination of any action, suit or proceeding by judgment, order, settlement, 
conviction, or upon a plea of nolo contendere or its equivalent shall not, of 
itself, create a presumption that the person did not act in good faith and in 
a manner which he or she reasonably believed to be in or not opposed to the 
best interests of the Corporation or, with respect to any criminal action or 
proceeding, that the person had reasonable cause to believe that his or her 
conduct was unlawful.

     2.   To the extent not prohibited by law, the Corporation shall 
indemnify any person who was or is a party, or is threatened to be made a 
party to any threatened, pending or completed action or suit by or in the 
right of the Corporation to procure a judgment in its favor by reason of the 
fact that such person is or was a director of the Corporation, or is or was 
serving at the request of the Corporation as a director of another 
corporation, partnership, joint venture, trust or other enterprise, against 
expenses (including attorneys' fees) actually and reasonably incurred by such 
person in connection with the defense or settlement of such action or suit, 
if such person acted in good faith and in a manner he or she reasonably 
believed to be in, or not opposed to, the best interests of the Corporation 
provided that, no indemnification shall be made with respect to any claim, 
issue, or matter as to which such person has been adjudged to have been 
liable to the Corporation, unless, and only to the extent that the court in 
which such action or suit was brought shall determine upon application that, 
despite the adjudication of liability, but in view of all the circumstances 
of the case, such person is fairly and reasonably entitled to indemnity for 
such expenses as the court shall deem proper.

     3.  Any indemnification under subsection 1 or 2  of this Article 
TWELFTH (unless ordered by a court) shall be made by the Corporation only 
as authorized in the specific case upon a determination that indemnification 
of the director is proper in the circumstances because he or she has met the 
applicable standard of conduct set forth in Subsections 1 and 2 of this 
Article.  Such determination shall be made (a) by the Board of Directors by a 
majority vote of a quorum consisting of directors who were not parties to 
such action, suit or proceeding, or (b) if such a quorum is not obtainable 
or, even if obtainable, a quorum of disinterested directors so directs, by 

                                       9

<PAGE>

advice of independent legal counsel, or (c) by the shareholders.  In any 
determination denying indemnification, the burden of proof shall be on the 
Corporation to prove by clear and convincing evidence that indemnification 
should not be allowed.

     4.   Notwithstanding any other provisions of this Article TWELFTH, 
expenses incurred in defending a civil or criminal action, suit or proceeding 
shall, unless the Board of Directors determines otherwise, be paid by the 
Corporation in advance of the final disposition of such action, suit or 
proceeding upon receipt of an undertaking by or on behalf of the director to 
repay such amount, if it shall ultimately be determined that he or she is not 
entitled to be indemnified by the Corporation as authorized in this Article 
THIRTEENTH.

     5.  Notwithstanding any other provisions of this Article TWELFTH, to 
the extent that a director of the Corporation has been successful, on the 
merits or otherwise, in the defense of any action, suit or proceeding 
referred to in subsections 1 and 2 of this Article THIRTEENTH or in defense 
of any claim, issue or matter therein, such person shall be indemnified 
against expenses (including attorneys fees) actually and reasonably incurred 
by such person in connection therewith.

     6. The indemnification and advancement of expenses provided by or 
granted under the other subsections of this Article TWELFTH shall not be 
deemed exclusive of any other rights to which those seeking indemnification 
or advancement of expenses may be entitled under any by-law, agreement, vote 
of shareholders or disinterested directors or otherwise, both as to action in 
his or her official capacity and as to action in another capacity while 
holding such office.

                                      10

     7.  The Corporation may purchase and maintain insurance on behalf of any 
person who is or was a director, officer, employee or agent of the 
Corporation or who is or was serving at the request of the Corporation as a 
director, officer, employee or agent of another corporation, partnership, 
joint venture, trust or other enterprise, against any liability asserted 
against such person and incurred by such person in any such capacity, or 
arising out of his or her status as such, whether or not the Corporation 
would have the power to indemnify such person against such liability under 
the provisions of this Article TWELFTH.

     8.  If the Corporation has paid indemnity or has advanced expenses to a 
director, officer, employee or agent, the Corporation shall report the 
indemnification or advance in writing to the shareholders with or before the 
notice of the next shareholders meeting.

     9.  For purposes of this Article TWELFTH, references to "the 
Corporation" shall include, in addition to the surviving Corporation, any 
merging Corporation (including any Corporation having merged with a merging 
Corporation) absorbed in a merger which, if its separate existence had 
continued would have had the power and authority to indemnify its directors, 
officers, and employees or agents, so that any person who was a director, 
officer, employee or agent of such merging Corporation, or was serving at the 
request of such merging Corporation as a director, officer, employee or agent 
of another corporation, partnership, joint venture, trust or other 
enterprise, shall stand in the same position under the provisions of this 
Article TWELFTH with respect to the surviving Corporation as such person 
would have with respect to such merging Corporation if its separate existence 
had continued.

                                      11

<PAGE>

          For purposes of this Article TWELFTH, references to other 
enterprises, shall include employee benefit plans; references to "fines" 
shall include any excise taxes assessed on a person with respect to an 
employee benefit plan; and references to "serving at the request of the 
Corporation" shall include any service as a director, officer, employee or 
agent of the Corporation which imposes duties on, or involves services by 
such director, officer, employee, or agent with respect to an employee 
benefit plan, its participants, or beneficiaries; A person who acted in good 
faith and in a manner he or she reasonably believed to be in the best 
interests of the participants and beneficiaries of an employee benefit plan 
shall be deemed to have acted in a manner "not opposed to the best interest 
of the Corporation" as referred to in this Article TWELFTH.

     10.  The Corporation may, to the extent authorized from time to time by 
the Board of Directors, grant rights to indemnification, and to the 
advancement of expenses, to any officer, employee or agent of the Corporation 
to the fullest extent of the provisions of this Article TWELFTH with 
respect to the indemnification and advancement of expense of directors of the 
Corporation.

     11.  The indemnification and advancement of expenses provided by or 
granted under this Article TWELFTH shall, unless otherwise provided when 
authorized or ratified, continue as to a person who has ceased to be a 
director, officer, employees or agent and shall inure to the benefit of the 
heirs, executors, and administrators of that person.

     12.  Any payments made to any indemnified party under these Articles of 
Incorporation or under any other right to indemnification shall be deemed to 
be an ordinary and necessary business 


                                      12

expense of the Corporation, and payment thereof shall not subject any person 
responsible for the payment, or the Board of Directors, to any action for 
corporate waste or to any similar action.

                              EMPLOYMENT AGREEMENT


     THIS AGREEMENT ("Agreement") is entered into as of September 19, 1996 by
and between Neil Taylor ("Taylor") and Taylor Industrial Software Inc., an
Alberta corporation (the "Company").

                                R E C I T A L S:

     A.   The Company desires to employ Taylor as an executive officer of the
Company and Taylor desires to be so employed by the Company, all on the terms
and subject to the conditions set forth herein.

     B.   The Company desires to bind Taylor to certain restrictive covenants
and Taylor agrees to be so bound, all on the terms and subject to the conditions
set forth herein.

                               A G R E E M E N T :

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

     1.   TERM.  Subject to the terms and conditions set forth herein and unless
sooner terminated as hereinafter provided, the Company shall employ Taylor and
Taylor agrees to serve as an employee of the Company from the date hereof to and
including September 19, 1999 (the "Employment Term").  After the expiration of
the Employment Term, Taylor's employment hereunder shall automatically renew for
successive one year periods (each, a "Renewal Term") unless either party hereto
delivers written notice to the other party hereto, at least ninety (90) days
prior to the expiration of the Employment Term or any Renewal Term thereof, as
the case may be, of his or its desire to terminate Taylor's employment with the
Company.  The Employment Term and any Renewal Term thereof are collectively
referred to herein as the "Term".

     2.   EMPLOYMENT DUTIES.  During the Term, Taylor shall serve as the 
Senior Vice President of Software Development of the Company and as the head 
of the TESS Business Unit.  Taylor shall report directly to the Board of 
Directors of the Company.  Taylor shall faithfully, diligently and 
competently perform such duties and responsibilities as may from time to time 
be assigned to him by the Board of Directors of the Company (the "Board").   
Taylor agrees that at all times during the Term and thereafter, (a) the 
Company shall have the right to display, and may use in its advertising the 
name and portrait of Taylor; (b) if applicable, the Company shall have the 
right to advertise its business as being carried on in the manner and 
tradition and according to the standards established by Taylor; and (c) 
Taylor will not knowingly or intentionally do any act or say any thing which 
will or may impair, damage, or destroy the good will and esteem for the 
Company of its suppliers, employees, patrons, customers and others who may at 
any time have or have had business relations with the Company.

<PAGE>

     3.   COMPENSATION.  As compensation for the services to be performed and
the duties and responsibilities to be assumed by Taylor during the Term, the
Company shall pay to Taylor a salary (the "Salary") in an amount equal to $U.S.
125,000 per annum.  The Company shall review the Salary payable to Taylor after
the expiration of each one year period during the Term beginning on the date
hereof and any increases in Salary shall be made at the sole discretion of the
Company.  The Salary shall be payable to Taylor in accordance with the Company's
ordinary payment practices for salaried employees.
     
     4.   BENEFITS.  

          (a)  During the Term, Taylor shall be entitled to participate in such
     employee benefit plans and programs as are maintained by the Company, to
     the extent that his position, tenure, compensation, age, health and other
     qualifications make him eligible to participate.  The Company does not
     promise the adoption or continuance of any particular plan or program
     during the Term, and Taylor's (and his dependents') participation in any
     such plan or program shall be subject to the provisions, rules, regulations
     and laws applicable thereto.  

          (b)  During the Term, Taylor shall be entitled to such other fringe
     benefits as are provided to employees of the Company with comparable
     positions, tenure and compensation as Taylor.

     5.   REIMBURSEMENT OF EXPENSES.  During the Term, Taylor shall be entitled
to prompt reimbursement for ordinary, necessary and reasonable out-of-pocket
trade or business expenses which Taylor incurs in connection with performing his
duties under this Agreement.  The reimbursement of all such expenses shall be
made upon presentation of evidence reasonably satisfactory to the Company of the
amounts and nature of such expenses and shall be subject to the reasonable
approval of the Board. 

     6.   RESTRICTIVE COVENANTS.  Taylor acknowledges and agrees that (a)
through his past and continuing services to the Company, he will learn valuable
trade secrets and other proprietary information relating to the Company's
business; (b) Taylor's services to the Company are unique in nature; (c) the
Company's business is international in scope; and (d) the Company would be
irreparably damaged if Taylor was to provide services to any person or entity in
violation of the restrictions contained in this Agreement.  Accordingly, as an
inducement to the Company to enter into this Agreement, Taylor agrees that
during the Term and for two years thereafter (such period being referred to
herein as the "Restricted Period"), Taylor shall not, directly or indirectly,
either for himself or for any other person or entity, without the prior written
consent of the Company:

          (a)  anywhere in the United States or Canada, engage or participate
     in, or assist, advise or be connected with (including as an employee,
     owner, partner, shareholder, officer, director, advisor, consultant, agent
     or (without limitation by the specific enumeration of the foregoing)
     otherwise), or permit his name to be used by or render services for, any
     person or entity engaged in, or making plans to engage in, a business that

                                       2
<PAGE>

     competes with the business conducted by, or proposed to be conducted by,
     the Company or Total Control Products, Inc. ("TCP"), the majority
     shareholder of the Company (a "Competing Business");

          (b)  solicit, attempt to solicit, aid in the solicitation of or accept
     any orders from any person or entity who is or has been a customer of the
     Company or its Affiliates, at any time during the period beginning one year
     prior to the expiration of the Term through the Restricted Period, to
     purchase products or services from any person or entity which products or
     services could have been supplied or performed, as the case may be, by the
     Company or its Affiliates (other than from the Company or its Affiliates);

          (c)  solicit, attempt to solicit or aid in the solicitation of any
     person or entity who is or has been a customer, supplier, licensor,
     licensee or person or entity having any other business relationship with
     the Company or any of its Affiliates, at any time during the period
     beginning one year prior to the expiration of the Term through the
     Restrictive Period, to cease doing business with or alter its business
     relationship with the Company or its Affiliates; or 

          (d)  solicit or hire any person or entity who is a director, officer,
     employee, independent contractor or agent of the Company or any of its
     Affiliates to perform services for any person or entity other than the
     Company or its Affiliates or to terminate his or her employment with the
     Company or its Affiliates.  

Additionally, as an inducement to the Company to enter into this Agreement,
Taylor agrees that during the Term, Taylor shall not, directly or indirectly,
either for himself or for any other person or entity, without the prior written
consent of the Company, take any action which might divert from the Company or
any of its Affiliates (as defined herein) any opportunity (each, an
"Opportunity") which would be within the scope of the Company's or such
Affiliate's then business and shall offer each Opportunity to the Company, which
the Company may, in its sole discretion, decide to pursue or not.  As used
herein, an "Affiliate" shall mean and include any person or entity which
controls a party, which such party controls or which is under common control
with such party.  For purposes of this Agreement, the Affiliates of the Company
shall specifically include TCP.  "Control" means the power, direct or indirect,
to direct or cause the direction of the management and policies of a person or
entity through voting securities, contract or otherwise.  Notwithstanding the
foregoing, the ownership of up to 5% of the issued capital stock of any publicly
traded company by itself shall not constitute a violation of any provision of
this Section 6.  Notwithstanding the foregoing, actions taken by Taylor pursuant
to the terms of that certain Secured Note dated as of the date hereof executed
by the Company in favor of Taylor shall not constitute a violation of the
provisions of this Section 6.

     7.   DISCLOSURE OF CONFIDENTIAL INFORMATION.  Taylor recognizes that he
will occupy a position of trust and confidence with the Company as to
Confidential Information (as herein defined) pertaining to the Company and its
Affiliates.  As an inducement for the Company to enter into this Agreement,
Taylor therefore agrees that:

          (a)  for the longest period permitted by law from the date of this
     Agreement, Taylor and each Affiliate of Taylor shall hold in the strictest
     confidence and shall not, other than as required by law, without the prior
     written consent of the Company, use for his own benefit or that of any
     third party or disclose to any person, firm or corporation (except the
     Company, an Affiliate of the Company or employees of the Company and its
     Affiliates) any Confidential Information.  For purposes of this Agreement,
     intending that the term shall be broadly construed to include anything
     protectible as a trade secret or confidential information under applicable
     law, "Confidential Information" shall mean all information, and all
     documents and other tangible items which record information relating to or
     useful in connection with the Company's business (including the business of
     any of the Company's Affiliates), which at the time or times concerned is
     protectible as a trade secret or confidential information under applicable
     law, and which has been or is from time to time disclosed to or known by
     Taylor either before or after the date hereof.
     
          (b)  Taylor and each Affiliate of Taylor (and if deceased, their
     personal representatives) shall promptly following a request therefor from
     the Company return to the Company, without retaining copies, all tangible
     items which are or which contain Confidential Information.  Taylor shall
     also surrender all computer print-outs, laboratory books, floppy disks and
     other such media for storing software and information, work papers, files,
     client lists, telephone and/or address books, rolodex cards, internal
     memoranda, appointment books, calendars, keys and other tangible things
     entrusted to Taylor by the Company or authored in whole or in part by
     Taylor within the scope of his duties to the Company even if such things do
     not contain Confidential Information; and

          (c)  at the request of the Company made at any time or from time to
     time during the Restricted Period, Taylor and each Affiliate of Taylor (and
     if deceased, their personal representatives) shall make, execute and
     deliver all applications, papers, assignments, conveyances, instruments or
     other documents and shall perform or cause to be performed such other
     lawful acts as the Company may reasonably deem necessary or desirable to
     implement any of the provisions of this Agreement, and shall give testimony
     and cooperate with the Company, its Affiliates or their respective
     representatives in any controversy or legal proceedings involving the
     Company, its Affiliates or their respective representatives with respect to
     any Confidential Information.

     8.   INVENTIONS.  Taylor acknowledges that in his capacity as an executive
officer of the Company, whether before or after the date hereof, he will be
involved in (i) the conception or making of improvements, discoveries,
inventions or the like (whether patentable or unpatentable and whether or not
reduced to practice), (ii) the authorship of copyrightable works or (iii) the
development of trade secrets or confidential information relating to the
Company.  Taylor

acknowledges that all such intellectual property is the exclusive property of 
the Company.  Taylor hereby waives any rights he may have in or to such 
intellectual property, and Taylor hereby assigns to the Company all right, 
title and interest in and to such intellectual property, including, without 
limitation, all copyright, neighboring rights and similar rights, title or 
interest.  Taylor waives any moral rights he may have under the Copyright Act 
or a similar law.  At the Company's request and at no expense to Taylor, 
Taylor shall execute and deliver all such papers, including, without 
limitation, any assignment documents, and shall provide such cooperation as 
may be necessary or desirable, or as the Company may reasonably request, in 
order to enable the Company to secure and exercise its rights to such 
intellectual property.

     9.   SPECIFIC PERFORMANCE.  Taylor agrees that any violation by him of
Sections 6, 7 or 8 of this Agreement would be highly injurious to the Company
and its Affiliates and would cause irreparable harm to the Company and its
Affiliates.  By reason of the foregoing, Taylor consents and agrees that if he
violates any provision of Sections 6, 7 or 8 of this Agreement, the Company and
its Affiliates shall be entitled, in addition to any other rights and remedies
that they may have, to apply to any court of competent jurisdiction for specific
performance and/or injunctive or other relief in order to enforce, or prevent
any continuing violation of, the provisions of such section.  In the event
Taylor breaches a covenant contained in this Agreement, the Restricted Period
applicable to Taylor with respect to such breached covenant shall be extended
for the period of such breach.  Taylor also recognizes that the territorial,
time and scope limitations set forth in Sections 6 and 7 are reasonable and are
properly required for the protection of the Company and its Affiliates and in
the event that any such territorial, time or scope limitation is deemed to be
unreasonable by a court of competent jurisdiction, the Company and Taylor agree,
and Taylor submits, to the reduction of any or all of said territorial, time or
scope limitations to such an area, period or scope as said court shall deem
reasonable under the circumstances.  Taylor represents, warrants and
acknowledges that he has available to him sufficient other means of support so
that observance of the covenants contained in Sections 6, 7 and 8 shall not
deprive him of his ability to earn a livelihood or support his dependents.

     10.  TERMINATION FOR CAUSE.  During the Term, Taylor's employment with the
Company may be terminated by the Board "for cause", which shall include (a)
Taylor's conviction for an indictable offence or a crime involving moral
turpitude; (b) Taylor's commission of an act which the Board, in its reasonable
discretion, determines involved personal dishonesty or fraud involving personal
profit in connection with Taylor's employment with the Company; (c) Taylor's
commission of an act which the Board shall have found to have involved willful
misconduct or gross negligence on the part of Taylor in the conduct of his
duties hereunder; or (d) Taylor's breach of any material provision of this
Agreement.  In the event of termination under this Section 10, the Company's
obligations under this Agreement shall cease and Taylor shall forfeit all his
rights to receive any compensation or benefits under this Agreement, except that
Taylor shall be entitled to his Salary and benefits for services already
performed as of the date of termination of this Agreement.

     11.  DEATH OR DISABILITY.  

          (a)  This Agreement shall terminate upon Taylor's death.

          (b)  If Taylor becomes permanently disabled (determined as provided
     below) during the Term, his employment with the Company shall terminate as
     of the date such permanent disability is determined.  Taylor shall be
     considered to be permanently disabled for purposes of this Agreement if he
     is unable by reason of accident or illness (including mental illness) to
     perform the material duties of his regular position with the Company and is
     (i) not expected to recover from his disability within a period of six (6)
     months from the commencement of the disability; or (ii) not expected to be
     able to perform his material duties of his regular position with the
     Company for a period of six (6) months in any consecutive twelve (12) month
     period as a result of the same disability.  If at any time Taylor claims or
     is claimed to be permanently disabled, a physician acceptable to both
     Taylor, or his personal representative, and the Company (which acceptances
     shall not be unreasonably withheld) shall be retained by the Company and
     shall examine Taylor.  Taylor shall cooperate fully with the physician.  If
     the physician determines that Taylor is permanently disabled, the physician
     shall deliver to the Company a certificate certifying both that Taylor is
     permanently disabled and the date upon which the condition of permanent
     disability commenced.  The determination of the physician shall be
     conclusive.

          (c)  Taylor's right to his compensation and benefits under this
     Agreement shall cease upon his death or disability, except that Taylor (or
     his estate or heirs) shall be entitled to his Salary and benefits for
     services already performed as of the date of his death or disability.

     12.  EFFECT OF TERMINATION.  The Company may terminate Taylor's employment
hereunder at any time for any reason.  Upon termination of Taylor's employment
with the Company for any reason other than death, disability or cause, the
Company shall pay Taylor his Salary through the remainder of the Employment Term
in accordance with the Company's ordinary payment practices for salaried
employees; provided, however, that upon termination for any reason other than
death, disability or cause, Taylor shall receive his Salary for at least a
period of twelve months.  Taylor shall accept such payment in full satisfaction
of any and all obligations he may have against the Company, whether statutory or
otherwise, and shall thereafter release the Company form any and all claims,
both present and future, that he may have against it.

     THIS AGREEMENT ("Agreement") is made as of the 12th day of December, 1996,
by and between TOTAL CONTROL PRODUCTS, INC., an Illinois corporation ("Total

     NOW, THEREFORE, in consideration of the premises and the mutual promises
contained herein, the parties agree as follows:

     1.   DEFINITIONS.  For the purpose of this Agreement, the following terms
shall have the meanings stated in this Section 1:

     (a)  "Digital Intellectual Property" means any and all of the following

secrets, unpatented formulations, manufacturing methods and other know-how, (ii)
copyrights, (iii) all patents on and pending applications to patent any

following that is owned by Total Control on, or any time after, the date 
hereof :  (i) trade secrets, unpatented formulations, manufacturing methods

Agreement.

     2.   JOINT DEVELOPMENT EFFORTS.  The parties agree to work together from
time to time in order to design and develop new or enhanced product offerings
for use in the industrial automation industry; provided, that the parties
expressly acknowledge  that neither party is under any obligation to complete
the design or development of any such new or enhanced product offerings.  The
parties acknowledge that the exact design specifications and parameters of such
new or enhanced product offerings have not been finalized as of the date hereof.

     3.   OWNERSHIP.

     (a)  Notwithstanding anything to the contrary contained herein, Digital
Electronics shall own and retain its right, title and interest in all Digital
Electronics Intellectual Property, and Total Control shall own and retain its
right, title and interest in all Total Control Intellectual Property.

     (b)  Ownership and all right, title and interest in all Joint Intellectual
Property shall be jointly held by Digital Electronics and Total Control.  Either
party shall be allowed to exploit the use of such Joint Intellectual Property

     5.   NO JOINT VENTURE; INDEPENDENT CONTRACTOR.  Digital Electronics and
Total Control are independent contractors and nothing in this Agreement is
intended to create an employment relationship, joint venture, license agreement
or partnership between the parties.  Neither party shall hold itself out as, or
take any action from which others might infer that it is, a partner, agent or
joint venturer of the other party.  In addition, neither party shall take any
action which binds, or purports to bind, the other party.

     6.   ARBITRATION.   (a) All disputes, differences or questions arising out
of or relating to this Agreement, or the validity, interpretation, breach,
violation, or termination thereof, shall be finally and solely determined and

existing Commercial Arbitration Rules of the American Arbitration Association. 
The parties also agree that the number of arbitrators shall be three (3), and
the language to be used in the arbitral proceedings shall be English.  In any
such arbitration proceedings, the arbitrators shall adopt and apply (i) the
substantive laws of the State of Illinois, USA, and (ii) the provisions of the



                                      -2-

<PAGE>

Federal Rules of Civil Procedure relating to discovery so that each party shall
allow and obtain discovery of any matter not privileged which is relevant to the
subject matter involved in the arbitration to the same extent as if such
arbitration were a civil action pending in a United States District Court.  The
arbitrators may grant any remedy or relief deemed to be just and equitable,
including, not limited to, specific performance and injunctive relief.  Judgment
upon any arbitration awards may be entered and enforced in any court of
competent jurisdiction.

          (b)  In the event any claims or actions, including arbitration, are
instituted to enforce any of the terms of this Agreement, the prevailing party
shall be entitled to reasonable attorneys' fees, costs, including all costs
related to the arbitration, and expenses.

          (c)  In no event shall any of the parties hereto be liable to another
for payment of any consequential damages resulting from the default in the
performance of their respective obligations under this Agreement.

     7.   COUNTERPARTS.  This Agreement may be executed in counterparts, each of
which shall be deemed an original.

     8.   NOTICES. All notices, reports and payments made pursuant to this 
Agreement shall be made in writing and shall be deemed sufficient if 
delivered or mailed by registered mail as follows: if to Digital Electronics, 
at 8-2-52, Nanko-Higashi, Suminoe-Ku, Osaka, Japan, or such other address 
Digital Electronics may hereafter designate in writing; if to Total Control, 
c/o Total Control Products, Inc., 2001 North Janice Avenue, Melrose Park, 
Illinois 60160, or such other address Total Control may hereafter designate 
in writing.

     9.   ENTIRE AGREEMENT.  This Agreement contains the entire Agreement
between the parties hereto and supersedes any and all previous agreements,
written or oral among the parties relating to the subject matter hereof.  No
amendment or modification of the terms of this Agreement shall be binding upon
any party unless reduced to writing and signed by both the parties hereto.

     10.  SEVERABILITY.  In the event any provision of this Agreement is held
invalid, the remaining provisions shall not be affected thereby.

internal laws of the State of Illinois, without giving effect to its laws
governing the conflict of laws.
