                           REOFFER/RESALE PROSPECTUS

                            GENCOR INDUSTRIES, INC.
                                        
                         3,556,000 SHARES COMMON STOCK
                               ($.10 Par Value)

     ISSUED PURSUANT TO THE GENCOR INDUSTRIES, INC. 1992 STOCK OPTION PLAN,
            1996 STOCK OPTION AGREEMENTS AND 1997 STOCK OPTION PLAN

     This Reoffer Prospectus (the "Prospectus") is being used in connection with
the reoffer or resale of shares of common stock, $.10 par value ("Common Stock")
of Gencor Industries, Inc., a Delaware corporation (the "Company" or "Gencor")
by certain directors, executive officers and key employees of the Company (named
under the caption and hereafter called "Selling Stockholders"), some of whom are
"affiliates" (as that term is defined in Rule 405 promulgated under the
Securities Act), who hold or may acquire shares of Common Stock issued pursuant
to the Gencor Industries, Inc. 1992 Stock Option Plan (the "1992 Plan"), the
1996 Stock Option Agreements (the "Option Agreements") and the 1997 Stock Option
Plan (the "1997 Plan")(the 1992 Plan and the 1997 Plan may sometimes be referred
to collectively as the "Plans") (the Plans and the Option Agreements may
sometimes be referred to collectively as the "Option Plans").

     Those shares of Common Stock that have been acquired pursuant to an
exercise of options granted under the Option Plans shall constitute "restricted
securities" as defined in Rule 144(a)(3) promulgated under the Securities Act.
The Common Stock that may be acquired pursuant to the terms and conditions of
the Option Plans by those Selling Stockholders who are also "affiliates" shall
constitute "control securities" as defined by Section C of the General
Instructions to Form S-8.

     Shares of Common Stock may be sold from time to time by a Selling
Stockholder directly to purchasers. Alternatively, a Selling Stockholder may
sell shares of Common Stock in one or more transactions (including block
transactions) on the American Stock Exchange ("AMEX"), in transactions occurring
in the public market off the AMEX, in privately negotiated transactions or in a
combination of such transactions. Each sale may be made either at market prices
prevailing at the time of such sale, at negotiated prices or at fixed prices,
which may be changed. Shares may be sold by Selling Stockholders through brokers
acting on behalf of such Selling Stockholders or to dealers for resale by such
dealers, and in connection with such sales, such brokers or dealers may receive
compensation in the form of discounts or commissions from such Selling
Stockholders and/or the purchasers of such shares for whom they may act as
broker or agent (which discounts or commissions may exceed those customary in
the types of transactions involved). In addition, any shares covered by this
Prospectus that qualify for sale pursuant to Rule 144 under the Securities Act
may be sold under Rule 144 rather than pursuant to this Prospectus.

     All expenses of registration incurred in connection with this offering are
being borne by the Company, but all brokerage commissions and other selling
expenses incurred by a Selling Stockholder will be borne by such Selling
Stockholder. The Company will not be entitled to any of the proceeds from any
sales of Common Stock by the Selling Stockholders, although the Company will
receive payment upon exercise of any options under which shares of Common Stock
are acquired for cash by a Selling Stockholder.

     The capital stock of the Company consists of Common Stock and Class B
Stock. Each share of Common Stock and Class B Stock is entitled to one vote per
share on all matters, except that, with respect to the election of directors,
holders of Class B Stock, voting separately as a class, may elect 75% of the

                                       
<PAGE>
 
members of the board of directors, and holders of Common Stock, voting
separately as a class, may elect the remaining 25% of the members of the board
of directors.

     The Company's Common Stock is listed on the AMEX under the symbol "GX." On
August 7, 1998, the last reported sale price of the Common Stock on the AMEX
Composite Tape was $16.9375 per share.

                                  THE COMPANY


THE FOLLOWING SUMMARY IS QUALIFIED IN ITS ENTIRETY BY THE MORE DETAILED
INFORMATION AND CONSOLIDATED FINANCIAL STATEMENTS AND NOTES THERETO APPEARING
ELSEWHERE IN THIS PROSPECTUS OR INCORPORATED HEREIN BY REFERENCE.

     The Company is a leading manufacturer of process machinery for a wide
variety of end-markets. Products include machinery used in the production of
highway construction materials such as hot-mix asphalt, and machinery used to
produce food products such as pelletized animal feeds, edible oils, sugar and
citrus juices. The Company believes it has significant market share positions in
its principal product lines. The Company's products are manufactured in 13
plants in the United States, Asia, Australia, Europe and South America and are
sold through a combination of Company sales representatives, independent dealers
and agents located throughout the world. The Company operates in two business
groups: the Construction Equipment Group ("CEG") and the Consolidated Process
Machinery Group ("CPM"). The core product in each group is "process machinery,"
designed to process and transform bulk materials into end products. As a result
of the similar technologies shared by both business groups, the Company believes
it is realizing operational synergies.

     CEG designs and manufactures machinery and related equipment used for the
production of asphalt and highway construction materials. CEG's principal
products include asphalt plants, combustion systems and fluid heat transfer
systems. CEG's technical and design capabilities, environmentally friendly
process technology and wide range of products have enabled it to become a
leading producer of asphalt production equipment worldwide. CEG's products are
sold primarily to the highway construction industry. The principal factors
driving demand for CEG's products are the level of government funding for
domestic highway construction and repair, infrastructure development in emerging
economies, the need for spare parts and a trend towards larger plants (e.g. drum
mix asphalt production) resulting from asphalt production plant consolidation.

Trail, Orlando, Florida 32810, telephone (407) 290-6000.


                                 RISK FACTORS

     This Prospectus and certain of the documents incorporated herein by
reference contain forward-looking statements that involve risks and
uncertainties. Statements in this Prospectus regarding future financial
performance and other statements containing the words "expect," "believe,"
"anticipate," "project," "estimate," "predict," "intend" and similar expressions
are forward-looking statements. The Company's actual results could differ
materially from those anticipated in such forward-looking statements as a result
of a variety of factors, including those set forth in the following risk factors
and elsewhere in this Prospectus. Prospective investors should consider
carefully the following factors, in addition to other information contained in
this Prospectus, prior to making an investment in the Common Stock.

     INTERNATIONAL EXPOSURE. International operations account for a significant
portion of its business and the Company anticipates that this will continue to
be the case for the foreseeable future. As a result, the Company may be subject
to certain risks, including difficulty in staffing and managing foreign
subsidiary operations, difficulty in managing distributors and dealers, adverse
tax consequences, political and economic instability of governments, and
difficulty in accounts receivable collection. The Company is subject to the
risks associated with the imposition of protective legislation and regulations,
including those relating to import or export or otherwise resulting from trade
or foreign policy, in the nations in which it now or in the future will conduct
business. The Company cannot predict whether quotas, duties, taxes or other
charges or restrictions will be implemented by the U.S. or any other country
upon the import or export of the Company's products. There can be no assurance
that any of these factors, or the adoption of restrictive policies, will not
have a material adverse effect on the Company's business, financial condition
and results of operations. In addition, the Company denominates some sales by
foreign subsidiaries in local currency, and an increase in the relative value of
the dollar against such currencies may lead to a reduction in sales and
earnings. The Company's foreign currency exposures generally are not hedged and
there can be no assurance that the Company's future results of operations and
investments will not be adversely affected by currency fluctuations.

     ACQUISITION STRATEGY; INTEGRATION OF ACQUIRED BUSINESSES. As part of its
growth strategy, the Company intends to evaluate the acquisitions of other
companies, assets or product lines that would complement or expand its existing
businesses or broaden its customer relationships. Although the Company conducts

                                       5

<PAGE>
 
due diligence reviews of potential acquisition candidates, the Company may not
be able to identify all material liabilities or risks related to potential
acquisition candidates. There can be no assurance that the Company will be able
to locate and acquire any business, retain key personnel and customers of an
acquired business or integrate any acquired business successfully, including the
recent acquisitions of PED, Gumaco and ACP. Additionally, there can be no
assurance that financing for any acquisition, if necessary, will be available on
acceptable terms, if at all, or that the Company will be able to accomplish its
strategic objectives in connection with any acquisition. Although the Company
periodically considers possible acquisitions, no specific acquisitions are
probable as of the date of this Prospectus.

     INDEBTEDNESS; FINANCIAL COVENANTS. The outstanding debt of the Company
represents a significant percentage of its total capitalization. The Company's
strategy contemplates continued strategic acquisitions, and a portion of the
cost of such acquisitions may be financed through additional indebtedness. There
can be no assurance that financing will continue to be available on terms
acceptable to the Company or at all. In the absence of such financing, the
Company's ability to respond to changing business and economic conditions, to
fund scheduled investments and capital expenditures, to make future acquisitions
and to absorb adverse operating results may be adversely affected.

     The Senior Secured Credit Agreement dated December 10, 1996, as amended to
date (the "Credit Facility") between the Company and the lenders party thereto
imposes certain financial and operating covenants upon the Company, including,
among others, restrictions on the ability of the Company to incur debt, or take
certain other corporate actions. The Credit Facility also limits the amount of
cash dividends that the Company may pay to a maximum of $250,000 per year,
subject to compliance with other loan covenants. In addition, the Credit
Facility requires that the Company maintain certain financial ratios and
provides for limitations on capital expenditures. The foregoing covenants may
restrict the Company's ability to obtain additional funds, dispose of assets, or
otherwise pursue its business strategies, and may impair the Company's ability
to obtain additional financing to fund future working capital requirements,
capital expenditures, acquisitions and other general corporate purposes. Changes
in economic or business conditions, results of operations or other factors could
in the future cause a violation of one or more covenants in the Credit Facility.

     CYCLICALITY OF DEMAND FOR COMPANY PRODUCTS. Demand for the Company's
products depends in part upon the level of capital and maintenance expenditures
by its industrial customers, in particular those by the highway construction
industry, commercial agricultural companies, integrated food producers, feed
mills and food processing and production companies. These industries
historically have been cyclical in nature and vulnerable to general downturns in
the economy. Decreases in industry spending could have a material adverse effect
upon demand for the Company's products and the Company's business, financial
condition and results of operations.

     The agricultural industry serviced by the Company is susceptible to
fluctuations caused by adverse weather, natural disasters, disease, governmental
policies and similar adversities and factors beyond the Company's control. For
example, as a result of the slaughter of animals caused by Mad Cow Disease and
Swine Flu, there was a reduction of shipments of pelleting equipment to Europe
by the Company's food processing division in the first six months of fiscal
1998. In addition, the effect on the Brazilian orange crop of adverse weather
during the 1997 growing season may impact demand for the Company's products by
the Brazilian citrus industry. General downturns in the agricultural sector, as
well as the highway construction industry, could have a material adverse effect
on the Company's business, financial condition and results of operations.

                                       6

     QUARTERLY VARIATIONS OF OPERATING RESULTS.  The Company's operating results
historically have fluctuated from quarter to quarter as a result of a number of
factors, including the value, timing and shipment of individual orders and the
mix of products sold. Moreover, although revenues from certain large system
contracts are recognized using the percentage of completion method of
accounting, the Company generally recognizes product revenues upon shipment of
its products. Accordingly, revenue in any quarter is primarily dependent on
product shipment.  The Company's asphalt production equipment operations are
subject to seasonal fluctuation, which may lower sales and result in possible
losses in the first and fourth fiscal quarters of each year. Traditionally,
asphalt producers do not purchase new equipment for shipment during the summer
and fall months to avoid disruption of their activities during peak periods of
highway construction. Pelleting and other food production equipment products are
less seasonal, but may result in lower demand in the second and third fiscal
quarters. The Company expects seasonality to have less of an influence on future
results of operations as it continues to add new companies and products and to
grow in international markets. However, there can be no assurance that such
additions and growth will reduce the seasonality of its product lines.

     COMPETITION.  The highway construction machinery and food process machinery
industries are highly competitive. In each of the lines of business in which the
Company provides goods and services, it competes with a variety of companies,
many of which have greater financial and other resources than the Company, or
are subsidiaries or divisions of larger organizations. In addition, the Company
may encounter competition from new market entrants. There can be no assurance
that competitors will not take actions, including developing new products, which
could adversely affect the Company's sales and operating results.

     DEPENDENCE ON KEY PERSONNEL.  The success of the Company's business will
continue to depend substantially upon the efforts, abilities and services of its
executive officers and certain other key employees. The loss of one or more key
employees could adversely affect the Company's operations. The Company's ability
to attract and retain qualified engineers and other professionals, either
through direct hiring, or acquisition of other businesses employing such
professionals, will also be an important factor in determining the Company's
future success.

     INTELLECTUAL PROPERTY MATTERS.  The Company holds numerous patents covering
technology and applications related to various products, equipment and systems,
and numerous trademarks and trade names registered with the U.S. Patent and
Trademark Office and in various foreign countries. There can be no assurance as
to the breadth or degree of protection that existing or future patents or
trademarks may afford the Company, or that any pending patent or trademark
applications will result in issued patents or trademarks, or that the Company's
patents, registered trademarks or patent applications, if any, will be upheld if
challenged, or that competitors will not develop similar or superior methods or
products outside the protection of any patents issued, licensed or sublicensed
to the Company. Although the Company believes that none of its patents,
technologies, products or trademarks infringe upon the patents, technologies,
products or trademarks of others, it is possible that its existing patent,
trademark or other rights may not be valid or that infringement of existing or
future patents, trademarks or proprietary rights may occur. In the event that
the Company's products are deemed to infringe upon the patent or proprietary
rights of others, the Company could be required to modify the design of its
products, change the name of its products or obtain a license for the use of
certain technologies incorporated into its products. There can be no assurance
that the Company would be able to do any of the foregoing in a timely manner,
upon acceptable terms and conditions, or at all, and the failure to do so could
have a material adverse effect on the Company. In addition, there can be no

                                       7

<PAGE>
 
assurance that the Company will have the financial or other resources necessary
to enforce or defend a patent, registered trademark or other proprietary right,
and, if the Company's products are deemed to infringe upon the patents,
trademarks or other proprietary rights of others, the Company could become
liable for damages, which could also have a material adverse effect on the
Company.

     PRODUCT LIABILITY.  The Company is engaged in a business that could expose
it to possible liability claims for personal injury or property damage due to
alleged design or manufacturing defects in the Company's products. The Company
believes that it meets existing professional specification standards recognized
or required in the industries in which it operates, and has had no material
product liability claims brought against it as of the date hereof. Although the
Company currently maintains product liability coverage which it believes is
adequate for the continued operation of its business, such insurance may prove
inadequate or become difficult to obtain or unobtainable in the future on terms
acceptable to the Company.

     ENVIRONMENTAL MATTERS.  The Company's operations are subject to federal,
state, local and foreign laws and regulations relating to the protection of the
environment. Sanctions for noncompliance may include revocation of permits,
corrective action orders, administrative or civil penalties and criminal
prosecution. The Company's business involves environmental management and issues
typically associated with historical manufacturing operations. To date, the
Company's cost of complying with environmental laws and regulations has not been
material, but the fact that such laws or regulations are changed frequently
makes predicting the cost or impact of such laws and regulations on its future
operations uncertain.

     SUPPLY AND PRICE OF RAW MATERIALS.  The principal raw materials used by the
Company are steel and related products. The Company has no long-term supply
agreements with any of its major suppliers. However, the Company has generally
been able to obtain sufficient supplies of raw materials for its operations, and
changes in prices of such materials historically have not had a significant
effect on its operations. Although the Company believes that such raw materials
are readily available from alternate sources, an interruption in the Company's
supply of steel and related products or a substantial increase in the price of
any of these raw materials could have a material adverse effect on the Company's
business, financial condition and results of operations.

     SYNTHETIC FUEL INVESTMENT.  Whether or not the Company will realize
economic benefits from its equity interest in Carbontronics, LLC
("Carbontronics") will depend, among other factors, on Carbontronics' four
synthetic fuel production plants ("Fuel Plants") being able to qualify for tax
credits under Section 29 of the Code and on the ability to produce and
successfully market synthetic fuel, if any, produced by the Fuel Plants.
Qualification for tax credits with regard to the synthetic fuel projects
requires satisfying a number of statutory criteria, and there can be no
guarantee that all of these criteria will be met. Failure to meet the statutory
requirements for any project could lead to the disqualification for tax credits.
Tax credits are based on the heating value of the synthetic fuel produced and
sold to unrelated parties.

     Construction of each Fuel Plant's related feed stock preparation facility
involves a substantial number of risks, including shortages of equipment,
material and labor, work stoppages, labor disputes, weather interference,
unforeseen engineering, environmental and geological problems and unanticipated
cost increases. Difficulties in obtaining or maintaining any requisite licenses
or permits could adversely affect the Company's Carbontronics holdings. The Fuel
Plant technology and equipment manufactured by the Company has only recently

                                       8

<PAGE>
 
been developed and there can be no assurance that any of the Fuel Plants will
operate as intended or that the technology to be employed in the projects will
result in commercially viable synthetic fuel products. Operation of the Fuel
Plants involves various risks, including the potential for breakdown or failure
of equipment, the inability to obtain adequate supplies of suitable feed stock
or binder material, or performance of the equipment below expected levels of
output or efficiency, failure to keep on hand adequate supplies of spare parts
or other raw materials, operator error, utility unavailability and catastrophic
events such as fires, floods and earthquakes. There is no assurance that the
synthetic fuel to be produced by the Fuel Plants can be marketed at prices and
on terms that are financially advantageous.

     The synthetic fuel projects will be required to comply with a number of
statutes and regulations relating to the health and safety of personnel and the
public, including the identification, generation, storage, handling,
transportation, disposal, record keeping, relating and reporting of and
emergency response in connection with materials relating to the facility that
may be hazardous or toxic, safety and health standards, practices and procedures
applicable to construction and operation of the facility, and environmental
protection requirements including standards and limitations relating to the
discharge of air and water pollutants and discharge of solid waste.

     GOVERNMENT REGULATIONS.  The Company is subject to a variety of
governmental regulations relating to the manufacturing of the Company's
products. Any failure by the Company to comply with present or future
regulations could subject it to future liabilities, or the suspension of
production that could have a material adverse effect on the Company's results of
operations. Such regulations could also restrict the Company's ability to expand
its facilities, or could require the Company to acquire costly equipment or to
incur other expenses to comply with such regulations. Although the Company
believes it has the design and manufacturing capability to meet all industry or
governmental agency standards that may apply to its product lines, including all
domestic and foreign environmental, structural, electrical and safety codes,
there can be no assurance that governmental laws and regulations will not become
more stringent over time, imposing greater compliance costs and increasing risks
and penalties associated with a violation. The cost to the Company of such
compliance to date has not materially affected the Company's business, financial
condition or results of operations. There can be no assurance, however, that
violations will not occur in the future as a result of human error, equipment
failure or other causes. The Company's customers are also subject to extensive
regulations, including those related to the workplace. The Company cannot
predict the nature, scope or effect of governmental legislation, or regulatory
requirements that could be imposed or how existing or future laws or regulations
will be administered, or interpreted. Compliance with more stringent laws or
regulations, as well as more vigorous enforcement policies of regulatory
agencies, could require substantial expenditures by the Company and could
adversely affect the Company's business, financial condition and results of
operations.

     YEAR 2000 COMPLIANCE.  Many existing computer systems and applications, and
other control devices use only two digits to identify a year in the date field,
without considering the impact of the upcoming change in the century. As a
result, such systems and applications could fail or create erroneous results
unless corrected so that they can process data related to the year 2000. The
Company relies on its computer systems, applications and devices in operating
and monitoring all major aspects of its business, including financial systems,
customer services, infrastructure, embedded computer chips, networks and
telecommunications equipment and end products. The Company is in the process of
upgrading its software to address the year 2000 issue. The Company currently
estimates that the costs associated with the year 2000 issue, and the

                                       9

<PAGE>
 
consequences of incomplete or untimely resolution of the year 2000 issue, will
not have a material adverse effect on the results of operations or financial
position of the Company.

     EFFECTIVE VOTING CONTROL BY PRINCIPAL STOCKHOLDERS.  The Company's
executive officers and directors beneficially own an aggregate of approximately
96.0% of the outstanding shares of the Company's $.10 par value Class B Stock
("Class B Stock"). The Class B Stock is entitled to elect 75% (calculated to the
nearest whole number, rounding five-tenths to next highest whole number) of the
members of the board of directors of the Company. As a result, these
stockholders can elect more than a majority of the board of directors of the
Company and exercise significant influence over most matters requiring approval
by the Company's stockholders. This concentration of control may also have the
effect of delaying or preventing a change in control of the Company.


                                USE OF PROCEEDS

  *  Indicates less than 1% ownership.

(1)  In accordance with Rule 13d-3 of the Securities Exchange Act of 1934, as
     amended, shares that are not outstanding, but that are subject to option,
     warrants, rights or conversion privileges exercisable within 60 days of the
     date of this Prospectus have been deemed to be outstanding for the purpose
     of computing the percentage of outstanding shares owned by the individual
     having such right but have not been deemed outstanding for the purpose of
     computing the percentage for any other person.

(2)  This does not constitute a commitment to sell any or all of the stated
     number of shares of Common Stock.  The number of shares offered shall be
     determined from time to time by each Selling Stockholder at his or her sole
     discretion.  This Registration Statement pertains to the Company's Common
     Stock that (i) underlies the stock options granted pursuant to the Option

     400,000 shares of Common Stock and 400,000 shares of Class B Stock as
     available of stock option grants thereunder. The 1996 Option Agreements
     granted 200,000 options for the purchase of 200,000 shares of Common Stock
     and 156,000 options for the purchase of Class B Stock.  The 1997 Plan

     The preceding table reflects all Selling Stockholders who are also
Affiliates and who are eligible to reoffer and resell Common Stock, whether or
not they have a present intent to do so. At the date of this Prospectus, the
Company does not know the names of all the persons who intend to resell shares
of Common Stock of the Company to be acquired pursuant to the Option Plans.
There can be no assurance that any of the Selling Stockholders will sell any or
all of the Common Stock offered by them hereunder. The Selling Stockholders will
be directors, employees or executive officers of the Company or its subsidiaries
who have been or may be granted options under the Option Plans. The Company will
supplement this Prospectus with the names of additional Selling Stockholders not
shown in the table above and the amount of shares of Common Stock to be
reoffered by them as that information becomes known, unless such Selling
Stockholders are not Affiliates and are selling no more than 1,000 shares
issuable under each plan, or unless the aggregate holdings of the non-Affiliated
group not shown in the table is less than 1% of the class of total shares
registered hereby.


                              PLAN OF DISTRIBUTION
                                        
     Since the Selling Stockholders may offer all or part of the shares of
Common Stock which they may hold upon exercise of options, and since this
offering is not being underwritten on a firm commitment basis, no estimate can
be given as to the amount of shares of Common Stock to be offered for sale by
the Selling Stockholders.

     The Selling Stockholders may sell or distribute some or all of the shares
of Common Stock offered by this Prospectus from time to time through dealers or
brokers or directly to one or more purchasers, including pledgees, in
transactions (which may involve block transactions) on the AMEX, in transactions
occurring in the public market off the AMEX, privately negotiated transactions
(including sales pursuant to pledges), or in a combination of such transactions.
Such transactions may be effected by the Selling Stockholders at market prices
prevailing at the time of sale, at prices related to such prevailing market
prices, at negotiated prices, or at fixed prices, which may be changed. Brokers
or dealers participating in such transactions as agents may receive compensation
in the form of discounts, concessions or commissions from the Selling
Stockholders (and, if they act as agent for the purchasers of such shares, from
such purchasers). Such discounts, concessions or commissions as to a particular
broker or dealer might be in excess of those customary in the type of
transaction involved. This Prospectus also may be used, with the Company's
consent, by donees of the Selling Stockholders, or by other persons acquiring
shares and who wish to offer and sell such shares under circumstances requiring
or making desirable its use. In addition, any securities covered by this
Prospectus which qualify for sale pursuant to Rule 144 of the

                                       12

<PAGE>
 
Securities Act, may be sold under Rule 144 rather than pursuant to this
Prospectus.

     The Selling Stockholders and any such brokers or dealers that participate
in such distribution may be deemed to be "underwriters" within the meaning of
the Securities Act, and any discounts, commissions or concessions received by
any such brokers or dealers might be deemed to be underwriting discounts and
commissions under the Securities Act. Neither the Company nor the Selling
Stockholders can presently estimate the amount of such compensation. The Company
knows of no existing arrangements between any Selling Stockholders and any other
Selling Stockholder, broker or dealer relating to the sale or distribution of
the shares.

     Under applicable rules and regulations under the Exchange Act, any person
engaged in a distribution of any of the shares may not simultaneously engage in
market activities with respect to the Common Stock for a period of five business
days prior to the commencement of such distribution. In addition and without
limiting the foregoing, the Selling Stockholders will be subject to applicable
provisions of the Exchange Act and the rules and regulations thereunder,
including Regulation M, which provisions may limit the timing of purchases and
sales of any of the shares by the Selling Stockholders. All of the foregoing may
affect the marketing of the Common Stock.

     The Company will pay substantially all of the expenses incident to this
offering of the shares by the Selling Stockholders to the public other than
commissions and discounts of underwriters, brokers, dealers or agents. Each
Selling Stockholder may indemnify any broker or dealer that participates in
transactions involving sales of the shares against certain liabilities,
including liabilities arising under the Securities Act.

     In order to comply with certain states' securities laws, if applicable, the
shares will be sold in such jurisdictions only through registered or licensed
brokers or dealers. In addition, in certain states the Common Stock may not be
sold unless the Common Stock has been registered or qualified for sale in such
state or an exemption from registration or qualification is available and is
complied with.

     The Company will receive no portion of the proceeds from the sale of the
shares of Common Stock and will bear all expenses related to the registration of
this offering of the shares of Common Stock.

ITEM 6.   INDEMNIFICATION OF DIRECTORS AND OFFICERS.

     Section 145 of the Delaware General Corporation Law of the State of
Delaware sets forth the conditions and limitations governing the
indemnifications of officers, directors and other parties.

     Article VI of the Company's By-Laws (the "By-Laws") provides in part that
the Company shall indemnify any director or officer 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, by
reason of the fact that he or she is or was a director, officer, employee or
agent of the Company, or is or was serving at the request of the Company, as a
director, officer, employee or agent of certain other entities, against all
expense, liability and loss reasonably incurred or suffered by such person in
connection with such action, suit or proceeding, and under certain
circumstances, whether or not the indemnified liability arises or arose from any
threatened, pending or completed action by or in the right of the Company.
Responsibility for determinations with respect to such indemnifications shall be
made by the Board of Directors, by independent legal counsel or by the
stockholders of the Company.

     Both the General Corporation Law of the State of Delaware and Article VI,
Section 2 of the Company's By-Laws provide that the Company may maintain
insurance to cover loss incurred pursuant to liability to directors and officers
of the Company arising under the Securities Act.

     Insofar as indemnification for liabilities arising under the Securities Act
may be permitted to directors, officers and controlling persons of the Company
pursuant to the foregoing provisions, or otherwise, the Company has been advised
that in the opinion of the Securities and Exchange Commission such
indemnification is against public policy as expressed in the Securities Act and
is, therefore, unenforceable.


ITEM 7.   EXEMPTION FROM REGISTRATION CLAIMED.

     The restricted securities to be reoffered and resold pursuant to this
Registration Statement were issued in transactions exempt from registration
pursuant to Section 4(2) of the Securities Act. The transaction involved the
issuance of shares of Common Stock pursuant to the exercise of options or awards
granted under the 1997 Plan to an employee of the Company.

ITEM 9.   UNDERTAKINGS.

          (a)  The undersigned registrant hereby undertakes:

               (1)  To file, during any period in which offers or sales are
                    being made, a post-effective amendment to this registration
                    statement:

                    (i)    To include any prospectus required by Section
                           10(a)(3) of the Securities Act of 1933;

                    (ii)   To reflect in the prospectus any facts or events
                           arising after the effective date of the registration
                           statement (or the most recent post-effective
                           amendment thereof) which, individually or in the
                           aggregate, represent a fundamental change in the
                           information set forth in the registration statement.
                           Notwithstanding the foregoing, any increase or
                           decrease in volume of securities offered (if the
                           total dollar value of securities offered would not
                           exceed that which was registered) and any deviation
                           from the low or high and of the estimated maximum
                           offering range may be reflected in the form of
                           prospectus filed with the Commission pursuant to Rule
                           424(b) if, in the aggregate, the changes in volume
                           and price represent no more than 20 percent change in
                           the maximum aggregate offering price set forth in the
                           "Calculation of Registration Fee" table in the
                           effective registration statement;

                    (iii)  To include any material information with respect to
                           the plan of distribution not previously disclosed in
                           the registration

                           statement or any material change to such information
                           in the registration statement; provided, however,
                           that paragraphs (a)(1)(i) and (a)(1)(ii) shall not
                           apply if the registration statement is on Form S-3,
                           Form S-8 or Form F-3, and the information required to
                           be included in a post-effective amendment by those
                           paragraphs is contained in periodic reports filed
                           with or furnished to the Commission by the registrant
                           pursuant to Section 13 or Section 15(d) of the
                           Securities Exchange Act of 1934 that are incorporated
                           by reference in the registration statement.

               (2)  That, for the purpose of determining any liability under the
                    Securities Act of 1933, each such post-effective amendment
                    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.

               (3)  To remove from registration by means of a post-effective
                    amendment any of the securities being registered which
                    remain unsold at the termination of the offering.

          (b)  The undersigned registrant hereby undertakes that, for purposes
               of determining any liability under the Securities Act of 1933,
               each filing of the registrant's annual report pursuant to Section
               13(a) or Section 15(d) of the Securities Exchange Act of 1934
               that is incorporated by reference in the registration statement
               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.

          (c)  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, 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 Securities 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 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 Reoffer/Resale Prospectus which is filed as a part of this
Registration Statement has been prepared in accordance with the requirements of
Part I of Form S-3 and may be used for reoffers or resales of the shares of
Common Stock (as hereinafter defined) of the Company acquired by the persons
named therein pursuant to each of the Option Plans.

                     [THIS AREA INTENTIONALLY LEFT BLANK]
REOFFER/RESALE PROSPECTUS

                            GENCOR INDUSTRIES, INC.
                                        
                         3,556,000 SHARES COMMON STOCK
                               ($.10 Par Value)

     ISSUED PURSUANT TO THE GENCOR INDUSTRIES, INC. 1992 STOCK OPTION PLAN,
            1996 STOCK OPTION AGREEMENTS AND 1997 STOCK OPTION PLAN

     This Reoffer Prospectus (the "Prospectus") is being used in connection with
the reoffer or resale of shares of common stock, $.10 par value ("Common Stock")
of Gencor Industries, Inc., a Delaware corporation (the "Company" or "Gencor")
by certain directors, executive officers and key employees of the Company (named
under the caption and hereafter called "Selling Stockholders"), some of whom are
"affiliates" (as that term is defined in Rule 405 promulgated under the
Securities Act), who hold or may acquire shares of Common Stock issued pursuant
to the Gencor Industries, Inc. 1992 Stock Option Plan (the "1992 Plan"), the
1996 Stock Option Agreements (the "Option Agreements") and the 1997 Stock Option
Plan (the "1997 Plan")(the 1992 Plan and the 1997 Plan may sometimes be referred
to collectively as the "Plans") (the Plans and the Option Agreements may
sometimes be referred to collectively as the "Option Plans").

     Those shares of Common Stock that have been acquired pursuant to an
exercise of options granted under the Option Plans shall constitute "restricted
securities" as defined in Rule 144(a)(3) promulgated under the Securities Act.
The Common Stock that may be acquired pursuant to the terms and conditions of
the Option Plans by those Selling Stockholders who are also "affiliates" shall
constitute "control securities" as defined by Section C of the General
Instructions to Form S-8.

     Shares of Common Stock may be sold from time to time by a Selling
Stockholder directly to purchasers. Alternatively, a Selling Stockholder may
sell shares of Common Stock in one or more transactions (including block
transactions) on the American Stock Exchange ("AMEX"), in transactions occurring
in the public market off the AMEX, in privately negotiated transactions or in a
combination of such transactions. Each sale may be made either at market prices
prevailing at the time of such sale, at negotiated prices or at fixed prices,
which may be changed. Shares may be sold by Selling Stockholders through brokers
acting on behalf of such Selling Stockholders or to dealers for resale by such
dealers, and in connection with such sales, such brokers or dealers may receive
compensation in the form of discounts or commissions from such Selling
Stockholders and/or the purchasers of such shares for whom they may act as
broker or agent (which discounts or commissions may exceed those customary in
the types of transactions involved). In addition, any shares covered by this
Prospectus that qualify for sale pursuant to Rule 144 under the Securities Act
may be sold under Rule 144 rather than pursuant to this Prospectus.

     All expenses of registration incurred in connection with this offering are
being borne by the Company, but all brokerage commissions and other selling
expenses incurred by a Selling Stockholder will be borne by such Selling
Stockholder. The Company will not be entitled to any of the proceeds from any
sales of Common Stock by the Selling Stockholders, although the Company will
receive payment upon exercise of any options under which shares of Common Stock
are acquired for cash by a Selling Stockholder.

     The capital stock of the Company consists of Common Stock and Class B
Stock. Each share of Common Stock and Class B Stock is entitled to one vote per
share on all matters, except that, with respect to the election of directors,
holders of Class B Stock, voting separately as a class, may elect 75% of the
members of the board of directors, and holders of Common Stock, voting
separately as a class, may elect the remaining 25% of the members of the board
of directors.

     The Company's Common Stock is listed on the AMEX under the symbol "GX." On
August 7, 1998, the last reported sale price of the Common Stock on the AMEX
Composite Tape was $16.9375 per share.

                                  THE COMPANY

THE FOLLOWING SUMMARY IS QUALIFIED IN ITS ENTIRETY BY THE MORE DETAILED
INFORMATION AND CONSOLIDATED FINANCIAL STATEMENTS AND NOTES THERETO APPEARING
ELSEWHERE IN THIS PROSPECTUS OR INCORPORATED HEREIN BY REFERENCE.

     The Company is a leading manufacturer of process machinery for a wide
variety of end-markets. Products include machinery used in the production of
highway construction materials such as hot-mix asphalt, and machinery used to
produce food products such as pelletized animal feeds, edible oils, sugar and
citrus juices. The Company believes it has significant market share positions in
its principal product lines. The Company's products are manufactured in 13
plants in the United States, Asia, Australia, Europe and South America and are
sold through a combination of Company sales representatives, independent dealers
and agents located throughout the world. The Company operates in two business
groups: the Construction Equipment Group ("CEG") and the Consolidated Process
Machinery Group ("CPM"). The core product in each group is "process machinery,"
designed to process and transform bulk materials into end products. As a result
of the similar technologies shared by both business groups, the Company believes
it is realizing operational synergies.

     CEG designs and manufactures machinery and related equipment used for the
production of asphalt and highway construction materials. CEG's principal
products include asphalt plants, combustion systems and fluid heat transfer
systems. CEG's technical and design capabilities, environmentally friendly
process technology and wide range of products have enabled it to become a
leading producer of asphalt production equipment worldwide. CEG's products are
sold primarily to the highway construction industry. The principal factors
driving demand for CEG's products are the level of government funding for
domestic highway construction and repair, infrastructure development in emerging
economies, the need for spare parts and a trend towards larger plants (e.g. drum
mix asphalt production) resulting from asphalt production plant consolidation.

                                       4
CPM designs and manufactures process machinery used in the production of
scientifically compounded animal feeds, edible oils, sugar and fruit juice
concentrates. CPM's products include pellet mills, crushers, flakers, grinders,
crystallizers, centrifuges and equipment used to concentrate juices, including
presses, evaporators, heat exchangers and dryers. CPM's products are sold
primarily to commercial agricultural companies, integrated food producers, feed
mills and food processing companies. CPM's machinery enables its customers to
manufacture food products more efficiently and is a widely accepted method of
scientifically processing animal feed. Over the past several years, the domestic
food processing machinery industry has experienced strong growth, partly as a
result of rising demand from overseas markets which are increasingly adopting
U.S. food production technologies. The Company believes that as living standards
continue to improve worldwide, particularly in emerging economies, and the
fragmented food processing industry continues to consolidate, demand will
continue to grow for CPM's products.

     The Company's executive offices are located at 5201 North Orange Blossom
Trail, Orlando, Florida 32810, telephone (407) 290-6000.

                                 RISK FACTORS

     This Prospectus and certain of the documents incorporated herein by
reference contain forward-looking statements that involve risks and
uncertainties. Statements in this Prospectus regarding future financial
performance and other statements containing the words "expect," "believe,"
"anticipate," "project," "estimate," "predict," "intend" and similar expressions
are forward-looking statements. The Company's actual results could differ
materially from those anticipated in such forward-looking statements as a result
of a variety of factors, including those set forth in the following risk factors
and elsewhere in this Prospectus. Prospective investors should consider
carefully the following factors, in addition to other information contained in
this Prospectus, prior to making an investment in the Common Stock.

     INTERNATIONAL EXPOSURE. International operations account for a significant
portion of its business and the Company anticipates that this will continue to
be the case for the foreseeable future. As a result, the Company may be subject
to certain risks, including difficulty in staffing and managing foreign
subsidiary operations, difficulty in managing distributors and dealers, adverse
tax consequences, political and economic instability of governments, and
difficulty in accounts receivable collection. The Company is subject to the
risks associated with the imposition of protective legislation and regulations,
including those relating to import or export or otherwise resulting from trade
or foreign policy, in the nations in which it now or in the future will conduct
business. The Company cannot predict whether quotas, duties, taxes or other
charges or restrictions will be implemented by the U.S. or any other country
upon the import or export of the Company's products. There can be no assurance
that any of these factors, or the adoption of restrictive policies, will not
have a material adverse effect on the Company's business, financial condition
and results of operations. In addition, the Company denominates some sales by
foreign subsidiaries in local currency, and an increase in the relative value of
the dollar against such currencies may lead to a reduction in sales and
earnings. The Company's foreign currency exposures generally are not hedged and
there can be no assurance that the Company's future results of operations and
investments will not be adversely affected by currency fluctuations.

     ACQUISITION STRATEGY; INTEGRATION OF ACQUIRED BUSINESSES. As part of its
growth strategy, the Company intends to evaluate the acquisitions of other
companies, assets or product lines that would complement or expand its existing
businesses or broaden its customer relationships. Although the Company conducts

                                       5
due diligence reviews of potential acquisition candidates, the Company may not
be able to identify all material liabilities or risks related to potential
acquisition candidates. There can be no assurance that the Company will be able
to locate and acquire any business, retain key personnel and customers of an
acquired business or integrate any acquired business successfully, including the
recent acquisitions of PED, Gumaco and ACP. Additionally, there can be no
assurance that financing for any acquisition, if necessary, will be available on
acceptable terms, if at all, or that the Company will be able to accomplish its
strategic objectives in connection with any acquisition. Although the Company
periodically considers possible acquisitions, no specific acquisitions are
probable as of the date of this Prospectus.

     INDEBTEDNESS; FINANCIAL COVENANTS. The outstanding debt of the Company
represents a significant percentage of its total capitalization. The Company's
strategy contemplates continued strategic acquisitions, and a portion of the
cost of such acquisitions may be financed through additional indebtedness. There
can be no assurance that financing will continue to be available on terms
acceptable to the Company or at all. In the absence of such financing, the
Company's ability to respond to changing business and economic conditions, to
fund scheduled investments and capital expenditures, to make future acquisitions
and to absorb adverse operating results may be adversely affected.

     The Senior Secured Credit Agreement dated December 10, 1996, as amended to
date (the "Credit Facility") between the Company and the lenders party thereto
imposes certain financial and operating covenants upon the Company, including,
among others, restrictions on the ability of the Company to incur debt, or take
certain other corporate actions. The Credit Facility also limits the amount of
cash dividends that the Company may pay to a maximum of $250,000 per year,
subject to compliance with other loan covenants. In addition, the Credit
Facility requires that the Company maintain certain financial ratios and
provides for limitations on capital expenditures. The foregoing covenants may
restrict the Company's ability to obtain additional funds, dispose of assets, or
otherwise pursue its business strategies, and may impair the Company's ability
to obtain additional financing to fund future working capital requirements,
capital expenditures, acquisitions and other general corporate purposes. Changes
in economic or business conditions, results of operations or other factors could
in the future cause a violation of one or more covenants in the Credit Facility.

     CYCLICALITY OF DEMAND FOR COMPANY PRODUCTS. Demand for the Company's
products depends in part upon the level of capital and maintenance expenditures
by its industrial customers, in particular those by the highway construction
industry, commercial agricultural companies, integrated food producers, feed
mills and food processing and production companies. These industries
historically have been cyclical in nature and vulnerable to general downturns in
the economy. Decreases in industry spending could have a material adverse effect
upon demand for the Company's products and the Company's business, financial
condition and results of operations.

     The agricultural industry serviced by the Company is susceptible to
fluctuations caused by adverse weather, natural disasters, disease, governmental
policies and similar adversities and factors beyond the Company's control. For
example, as a result of the slaughter of animals caused by Mad Cow Disease and
Swine Flu, there was a reduction of shipments of pelleting equipment to Europe
by the Company's food processing division in the first six months of fiscal
1998. In addition, the effect on the Brazilian orange crop of adverse weather
during the 1997 growing season may impact demand for the Company's products by
the Brazilian citrus industry. General downturns in the agricultural sector, as
well as the highway construction industry, could have a material adverse effect
on the Company's business, financial condition and results of operations.

                                       6
QUARTERLY VARIATIONS OF OPERATING RESULTS.  The Company's operating results
historically have fluctuated from quarter to quarter as a result of a number of
factors, including the value, timing and shipment of individual orders and the
mix of products sold. Moreover, although revenues from certain large system
contracts are recognized using the percentage of completion method of
accounting, the Company generally recognizes product revenues upon shipment of
its products. Accordingly, revenue in any quarter is primarily dependent on
product shipment.  The Company's asphalt production equipment operations are
subject to seasonal fluctuation, which may lower sales and result in possible
losses in the first and fourth fiscal quarters of each year. Traditionally,
asphalt producers do not purchase new equipment for shipment during the summer
and fall months to avoid disruption of their activities during peak periods of
highway construction. Pelleting and other food production equipment products are
less seasonal, but may result in lower demand in the second and third fiscal
quarters. The Company expects seasonality to have less of an influence on future
results of operations as it continues to add new companies and products and to
grow in international markets. However, there can be no assurance that such
additions and growth will reduce the seasonality of its product lines.

     COMPETITION.  The highway construction machinery and food process machinery
industries are highly competitive. In each of the lines of business in which the
Company provides goods and services, it competes with a variety of companies,
many of which have greater financial and other resources than the Company, or
are subsidiaries or divisions of larger organizations. In addition, the Company
may encounter competition from new market entrants. There can be no assurance
that competitors will not take actions, including developing new products, which
could adversely affect the Company's sales and operating results.

     DEPENDENCE ON KEY PERSONNEL.  The success of the Company's business will
continue to depend substantially upon the efforts, abilities and services of its
executive officers and certain other key employees. The loss of one or more key
employees could adversely affect the Company's operations. The Company's ability
to attract and retain qualified engineers and other professionals, either
through direct hiring, or acquisition of other businesses employing such
professionals, will also be an important factor in determining the Company's
future success.

     INTELLECTUAL PROPERTY MATTERS.  The Company holds numerous patents covering
technology and applications related to various products, equipment and systems,
and numerous trademarks and trade names registered with the U.S. Patent and
Trademark Office and in various foreign countries. There can be no assurance as
to the breadth or degree of protection that existing or future patents or
trademarks may afford the Company, or that any pending patent or trademark
applications will result in issued patents or trademarks, or that the Company's
patents, registered trademarks or patent applications, if any, will be upheld if
challenged, or that competitors will not develop similar or superior methods or
products outside the protection of any patents issued, licensed or sublicensed
to the Company. Although the Company believes that none of its patents,
technologies, products or trademarks infringe upon the patents, technologies,
products or trademarks of others, it is possible that its existing patent,
trademark or other rights may not be valid or that infringement of existing or
future patents, trademarks or proprietary rights may occur. In the event that
the Company's products are deemed to infringe upon the patent or proprietary
rights of others, the Company could be required to modify the design of its
products, change the name of its products or obtain a license for the use of
certain technologies incorporated into its products. There can be no assurance
that the Company would be able to do any of the foregoing in a timely manner,
upon acceptable terms and conditions, or at all, and the failure to do so could
have a material adverse effect on the Company. In addition, there can be no

                                       7
assurance that the Company will have the financial or other resources necessary
to enforce or defend a patent, registered trademark or other proprietary right,
and, if the Company's products are deemed to infringe upon the patents,
trademarks or other proprietary rights of others, the Company could become
liable for damages, which could also have a material adverse effect on the
Company.

     PRODUCT LIABILITY.  The Company is engaged in a business that could expose
it to possible liability claims for personal injury or property damage due to
alleged design or manufacturing defects in the Company's products. The Company
believes that it meets existing professional specification standards recognized
or required in the industries in which it operates, and has had no material
product liability claims brought against it as of the date hereof. Although the
Company currently maintains product liability coverage which it believes is
adequate for the continued operation of its business, such insurance may prove
inadequate or become difficult to obtain or unobtainable in the future on terms
acceptable to the Company.

     ENVIRONMENTAL MATTERS.  The Company's operations are subject to federal,
state, local and foreign laws and regulations relating to the protection of the
environment. Sanctions for noncompliance may include revocation of permits,
corrective action orders, administrative or civil penalties and criminal
prosecution. The Company's business involves environmental management and issues
typically associated with historical manufacturing operations. To date, the
Company's cost of complying with environmental laws and regulations has not been
material, but the fact that such laws or regulations are changed frequently
makes predicting the cost or impact of such laws and regulations on its future
operations uncertain.

     SUPPLY AND PRICE OF RAW MATERIALS.  The principal raw materials used by the
Company are steel and related products. The Company has no long-term supply
agreements with any of its major suppliers. However, the Company has generally
been able to obtain sufficient supplies of raw materials for its operations, and
changes in prices of such materials historically have not had a significant
effect on its operations. Although the Company believes that such raw materials
are readily available from alternate sources, an interruption in the Company's
supply of steel and related products or a substantial increase in the price of
any of these raw materials could have a material adverse effect on the Company's
business, financial condition and results of operations.

     SYNTHETIC FUEL INVESTMENT.  Whether or not the Company will realize
economic benefits from its equity interest in Carbontronics, LLC
("Carbontronics") will depend, among other factors, on Carbontronics' four
synthetic fuel production plants ("Fuel Plants") being able to qualify for tax
credits under Section 29 of the Code and on the ability to produce and
successfully market synthetic fuel, if any, produced by the Fuel Plants.
Qualification for tax credits with regard to the synthetic fuel projects
requires satisfying a number of statutory criteria, and there can be no
guarantee that all of these criteria will be met. Failure to meet the statutory
requirements for any project could lead to the disqualification for tax credits.
Tax credits are based on the heating value of the synthetic fuel produced and
sold to unrelated parties.

     Construction of each Fuel Plant's related feed stock preparation facility
involves a substantial number of risks, including shortages of equipment,
material and labor, work stoppages, labor disputes, weather interference,
unforeseen engineering, environmental and geological problems and unanticipated
cost increases. Difficulties in obtaining or maintaining any requisite licenses
or permits could adversely affect the Company's Carbontronics holdings. The Fuel
Plant technology and equipment manufactured by the Company has only recently

                                       8
been developed and there can be no assurance that any of the Fuel Plants will
operate as intended or that the technology to be employed in the projects will
result in commercially viable synthetic fuel products. Operation of the Fuel
Plants involves various risks, including the potential for breakdown or failure
of equipment, the inability to obtain adequate supplies of suitable feed stock
or binder material, or performance of the equipment below expected levels of
output or efficiency, failure to keep on hand adequate supplies of spare parts
or other raw materials, operator error, utility unavailability and catastrophic
events such as fires, floods and earthquakes. There is no assurance that the
synthetic fuel to be produced by the Fuel Plants can be marketed at prices and
on terms that are financially advantageous.

     The synthetic fuel projects will be required to comply with a number of
statutes and regulations relating to the health and safety of personnel and the
public, including the identification, generation, storage, handling,
transportation, disposal, record keeping, relating and reporting of and
emergency response in connection with materials relating to the facility that
may be hazardous or toxic, safety and health standards, practices and procedures
applicable to construction and operation of the facility, and environmental
protection requirements including standards and limitations relating to the
discharge of air and water pollutants and discharge of solid waste.

     GOVERNMENT REGULATIONS.  The Company is subject to a variety of
governmental regulations relating to the manufacturing of the Company's
products. Any failure by the Company to comply with present or future
regulations could subject it to future liabilities, or the suspension of
production that could have a material adverse effect on the Company's results of
operations. Such regulations could also restrict the Company's ability to expand
its facilities, or could require the Company to acquire costly equipment or to
incur other expenses to comply with such regulations. Although the Company
believes it has the design and manufacturing capability to meet all industry or
governmental agency standards that may apply to its product lines, including all
domestic and foreign environmental, structural, electrical and safety codes,
there can be no assurance that governmental laws and regulations will not become
more stringent over time, imposing greater compliance costs and increasing risks
and penalties associated with a violation. The cost to the Company of such
compliance to date has not materially affected the Company's business, financial
condition or results of operations. There can be no assurance, however, that
violations will not occur in the future as a result of human error, equipment
failure or other causes. The Company's customers are also subject to extensive
regulations, including those related to the workplace. The Company cannot
predict the nature, scope or effect of governmental legislation, or regulatory
requirements that could be imposed or how existing or future laws or regulations
will be administered, or interpreted. Compliance with more stringent laws or
regulations, as well as more vigorous enforcement policies of regulatory
agencies, could require substantial expenditures by the Company and could
adversely affect the Company's business, financial condition and results of
operations.

     YEAR 2000 COMPLIANCE.  Many existing computer systems and applications, and
other control devices use only two digits to identify a year in the date field,
without considering the impact of the upcoming change in the century. As a
result, such systems and applications could fail or create erroneous results
unless corrected so that they can process data related to the year 2000. The
Company relies on its computer systems, applications and devices in operating
and monitoring all major aspects of its business, including financial systems,
customer services, infrastructure, embedded computer chips, networks and
telecommunications equipment and end products. The Company is in the process of
upgrading its software to address the year 2000 issue. The Company currently
estimates that the costs associated with the year 2000 issue, and the

                                       9
consequences of incomplete or untimely resolution of the year 2000 issue, will
not have a material adverse effect on the results of operations or financial
position of the Company.

     EFFECTIVE VOTING CONTROL BY PRINCIPAL STOCKHOLDERS.  The Company's
executive officers and directors beneficially own an aggregate of approximately
96.0% of the outstanding shares of the Company's $.10 par value Class B Stock
("Class B Stock"). The Class B Stock is entitled to elect 75% (calculated to the
nearest whole number, rounding five-tenths to next highest whole number) of the
members of the board of directors of the Company. As a result, these
stockholders can elect more than a majority of the board of directors of the
Company and exercise significant influence over most matters requiring approval
by the Company's stockholders. This concentration of control may also have the
effect of delaying or preventing a change in control of the Company.

                                USE OF PROCEEDS

  *  Indicates less than 1% ownership.

(1)  In accordance with Rule 13d-3 of the Securities Exchange Act of 1934, as
     amended, shares that are not outstanding, but that are subject to option,
     warrants, rights or conversion privileges exercisable within 60 days of the
     date of this Prospectus have been deemed to be outstanding for the purpose
     of computing the percentage of outstanding shares owned by the individual
     having such right but have not been deemed outstanding for the purpose of
     computing the percentage for any other person.

(2)  This does not constitute a commitment to sell any or all of the stated
     number of shares of Common Stock.  The number of shares offered shall be
     determined from time to time by each Selling Stockholder at his or her sole
     discretion.  This Registration Statement pertains to the Company's Common
     Stock that (i) underlies the stock options granted pursuant to the Option
     Plans (ii) underlies the stock options that have not yet been granted but
     which the Company may issue under the terms and conditions of the Option
     Plans, (iii) were obtained upon exercise of stock options granted pursuant
     to the Option Plans and (iv) were obtained upon the conversion of the
     shares of Class B Stock that were issued pursuant to the exercise of stock
     options granted under the Option Plans.  The 1992 Plan authorized up to
     400,000 shares of Common Stock and 400,000 shares of Class B Stock as
     available of stock option grants thereunder. The 1996 Option Agreements
     granted 200,000 options for the purchase of 200,000 shares of Common Stock
     and 156,000 options for the purchase of Class B Stock.  The 1997 Plan
     authorized up to 1,200,000 shares of Common Stock and 1,200,000 shares of
     Class B Stock as available of stock option grants thereunder.

(3)  Includes 120,000 shares owned jointly with John Elliott, 120,000 shares
     owned jointly with Marc Elliott and 380,000 shares of Common Stock issued
     to E.J. Elliott pursuant to the exercise of certain stock options granted
     under the 1992 Plan.  Also includes options to purchase 780,000 shares of
     Common Stock.

(4)  Includes 120,000 shares owned jointly with E.J. Elliott.

(5)  Includes options to purchase 418,000 shares of Class B Stock.

(6)  Assumes the exercise of 218,000 options to purchase Class B Stock and the
     subsequent conversion of the 218,000 shares of Class B Stock along with the
     200,000 shares of Class B Stock previously obtained through the

                                       11
exercise of certain options granted under the Option Plans to Common Stock
     and the subsequent sale thereof.

(7)  Includes options to purchase 60,000 shares of Common Stock.

(8)  Includes options to purchase 60,000 shares of Common Stock.

(9)  Includes options to purchase 80,000 shares of Common Stock.

(10) Includes 20,000 shares of Common Stock issued to Jacky Brenahan pursuant to
     the exercise of certain stock options granted under the 1997 Plan.

     The preceding table reflects all Selling Stockholders who are also
Affiliates and who are eligible to reoffer and resell Common Stock, whether or
not they have a present intent to do so. At the date of this Prospectus, the
Company does not know the names of all the persons who intend to resell shares
of Common Stock of the Company to be acquired pursuant to the Option Plans.
There can be no assurance that any of the Selling Stockholders will sell any or
all of the Common Stock offered by them hereunder. The Selling Stockholders will
be directors, employees or executive officers of the Company or its subsidiaries
who have been or may be granted options under the Option Plans. The Company will
supplement this Prospectus with the names of additional Selling Stockholders not
shown in the table above and the amount of shares of Common Stock to be
reoffered by them as that information becomes known, unless such Selling
Stockholders are not Affiliates and are selling no more than 1,000 shares
issuable under each plan, or unless the aggregate holdings of the non-Affiliated
group not shown in the table is less than 1% of the class of total shares
registered hereby.

                              PLAN OF DISTRIBUTION
                                        
     Since the Selling Stockholders may offer all or part of the shares of
Common Stock which they may hold upon exercise of options, and since this
offering is not being underwritten on a firm commitment basis, no estimate can
be given as to the amount of shares of Common Stock to be offered for sale by
the Selling Stockholders.

     The Selling Stockholders may sell or distribute some or all of the shares
of Common Stock offered by this Prospectus from time to time through dealers or
brokers or directly to one or more purchasers, including pledgees, in
transactions (which may involve block transactions) on the AMEX, in transactions
occurring in the public market off the AMEX, privately negotiated transactions
(including sales pursuant to pledges), or in a combination of such transactions.
Such transactions may be effected by the Selling Stockholders at market prices
prevailing at the time of sale, at prices related to such prevailing market
prices, at negotiated prices, or at fixed prices, which may be changed. Brokers
or dealers participating in such transactions as agents may receive compensation
in the form of discounts, concessions or commissions from the Selling
Stockholders (and, if they act as agent for the purchasers of such shares, from
such purchasers). Such discounts, concessions or commissions as to a particular
broker or dealer might be in excess of those customary in the type of
transaction involved. This Prospectus also may be used, with the Company's
consent, by donees of the Selling Stockholders, or by other persons acquiring
shares and who wish to offer and sell such shares under circumstances requiring
or making desirable its use. In addition, any securities covered by this
Prospectus which qualify for sale pursuant to Rule 144 of the

                                       12
Securities Act, may be sold under Rule 144 rather than pursuant to this
Prospectus.

     The Selling Stockholders and any such brokers or dealers that participate
in such distribution may be deemed to be "underwriters" within the meaning of
the Securities Act, and any discounts, commissions or concessions received by
any such brokers or dealers might be deemed to be underwriting discounts and
commissions under the Securities Act. Neither the Company nor the Selling
Stockholders can presently estimate the amount of such compensation. The Company
knows of no existing arrangements between any Selling Stockholders and any other
Selling Stockholder, broker or dealer relating to the sale or distribution of
the shares.

     Under applicable rules and regulations under the Exchange Act, any person
engaged in a distribution of any of the shares may not simultaneously engage in
market activities with respect to the Common Stock for a period of five business
days prior to the commencement of such distribution. In addition and without
limiting the foregoing, the Selling Stockholders will be subject to applicable
provisions of the Exchange Act and the rules and regulations thereunder,
including Regulation M, which provisions may limit the timing of purchases and
sales of any of the shares by the Selling Stockholders. All of the foregoing may
affect the marketing of the Common Stock.

     The Company will pay substantially all of the expenses incident to this
offering of the shares by the Selling Stockholders to the public other than
commissions and discounts of underwriters, brokers, dealers or agents. Each
Selling Stockholder may indemnify any broker or dealer that participates in
transactions involving sales of the shares against certain liabilities,
including liabilities arising under the Securities Act.

     In order to comply with certain states' securities laws, if applicable, the
shares will be sold in such jurisdictions only through registered or licensed
brokers or dealers. In addition, in certain states the Common Stock may not be
sold unless the Common Stock has been registered or qualified for sale in such
state or an exemption from registration or qualification is available and is
complied with.

     The Company will receive no portion of the proceeds from the sale of the
shares of Common Stock and will bear all expenses related to the registration of
this offering of the shares of Common Stock.

ITEM 6.   INDEMNIFICATION OF DIRECTORS AND OFFICERS.

     Section 145 of the Delaware General Corporation Law of the State of
Delaware sets forth the conditions and limitations governing the
indemnifications of officers, directors and other parties.

     Article VI of the Company's By-Laws (the "By-Laws") provides in part that
the Company shall indemnify any director or officer 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, by
reason of the fact that he or she is or was a director, officer, employee or
agent of the Company, or is or was serving at the request of the Company, as a
director, officer, employee or agent of certain other entities, against all
expense, liability and loss reasonably incurred or suffered by such person in
connection with such action, suit or proceeding, and under certain
circumstances, whether or not the indemnified liability arises or arose from any
threatened, pending or completed action by or in the right of the Company.
Responsibility for determinations with respect to such indemnifications shall be
made by the Board of Directors, by independent legal counsel or by the
stockholders of the Company.

     Both the General Corporation Law of the State of Delaware and Article VI,
Section 2 of the Company's By-Laws provide that the Company may maintain
insurance to cover loss incurred pursuant to liability to directors and officers
of the Company arising under the Securities Act.

     Insofar as indemnification for liabilities arising under the Securities Act
may be permitted to directors, officers and controlling persons of the Company
pursuant to the foregoing provisions, or otherwise, the Company has been advised
that in the opinion of the Securities and Exchange Commission such
indemnification is against public policy as expressed in the Securities Act and
is, therefore, unenforceable.

ITEM 7.   EXEMPTION FROM REGISTRATION CLAIMED.

     The restricted securities to be reoffered and resold pursuant to this
Registration Statement were issued in transactions exempt from registration
pursuant to Section 4(2) of the Securities Act. The transaction involved the
issuance of shares of Common Stock pursuant to the exercise of options or awards
granted under the 1997 Plan to an employee of the Company.

ITEM 9.   UNDERTAKINGS.

          (a)  The undersigned registrant hereby undertakes:

               (1)  To file, during any period in which offers or sales are
                    being made, a post-effective amendment to this registration
                    statement:

                    (i)    To include any prospectus required by Section
                           10(a)(3) of the Securities Act of 1933;

                    (ii)   To reflect in the prospectus any facts or events
                           arising after the effective date of the registration
                           statement (or the most recent post-effective
                           amendment thereof) which, individually or in the
                           aggregate, represent a fundamental change in the
                           information set forth in the registration statement.
                           Notwithstanding the foregoing, any increase or
                           decrease in volume of securities offered (if the
                           total dollar value of securities offered would not
                           exceed that which was registered) and any deviation
                           from the low or high and of the estimated maximum
                           offering range may be reflected in the form of
                           prospectus filed with the Commission pursuant to Rule
                           424(b) if, in the aggregate, the changes in volume
                           and price represent no more than 20 percent change in
                           the maximum aggregate offering price set forth in the
                           "Calculation of Registration Fee" table in the
                           effective registration statement;

                    (iii)  To include any material information with respect to
                           the plan of distribution not previously disclosed in
                           the registration

statement or any material change to such information
                           in the registration statement; provided, however,
                           that paragraphs (a)(1)(i) and (a)(1)(ii) shall not
                           apply if the registration statement is on Form S-3,
                           Form S-8 or Form F-3, and the information required to
                           be included in a post-effective amendment by those
                           paragraphs is contained in periodic reports filed
                           with or furnished to the Commission by the registrant
                           pursuant to Section 13 or Section 15(d) of the
                           Securities Exchange Act of 1934 that are incorporated
                           by reference in the registration statement.

               (2)  That, for the purpose of determining any liability under the
                    Securities Act of 1933, each such post-effective amendment
                    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.

               (3)  To remove from registration by means of a post-effective
                    amendment any of the securities being registered which
                    remain unsold at the termination of the offering.

          (b)  The undersigned registrant hereby undertakes that, for purposes
               of determining any liability under the Securities Act of 1933,
               each filing of the registrant's annual report pursuant to Section
               13(a) or Section 15(d) of the Securities Exchange Act of 1934
               that is incorporated by reference in the registration statement
               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.

          (c)  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, 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 Securities 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 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.
