                               PROSPECTUS SUMMARY
 
    THE FOLLOWING SUMMARY IS QUALIFIED IN ITS ENTIRETY BY THE MORE DETAILED
INFORMATION AND FINANCIAL STATEMENTS (INCLUDING THE NOTES THERETO) APPEARING
ELSEWHERE OR INCORPORATED BY REFERENCE IN THIS PROSPECTUS. UNLESS OTHERWISE
INDICATED, OR THE CONTEXT OTHERWISE REQUIRES, ALL INFORMATION IN THIS
PROSPECTUS: (I) REFLECTS THE ONE-FOR-THREE REVERSE STOCK SPLIT (THE "REVERSE
STOCK SPLIT") WHICH IS EXPECTED TO BE CONSUMMATED PRIOR TO THE EFFECTIVE DATE OF
THIS OFFERING AND (II) ASSUMES NO EXERCISE OF THE OVER-ALLOTMENT OPTION. UNLESS
THE CONTEXT OTHERWISE REQUIRES, REFERENCES IN THIS PROSPECTUS TO THE "COMPANY"
INCLUDE CHYRON CORPORATION AND ITS WHOLLY-OWNED SUBSIDIARIES, INCLUDING PRO-BEL
LIMITED, WHICH WAS ACQUIRED ON APRIL 12, 1996. INVESTORS SHOULD CAREFULLY
CONSIDER THE INFORMATION UNDER THE HEADING "RISK FACTORS."
 
    The Company develops, manufactures, markets and supports a broad range of
equipment, software and systems that facilitate the production and enhance the
presentation of live and pre-recorded video, audio and other data. The Company's
products enable users to (i) create and manipulate text, logos and other graphic
images using special effects such as three dimensional ("3D") transforming,
compositing and painting; (ii) manage, monitor and distribute video, audio and
other data signals; and (iii) control edit processes and automate broadcast
equipment. The worldwide market for equipment, software and systems used in the
production and presentation of video and audio content encompasses major
television networks, cable television broadcasters, direct to home satellite
program distributors, production companies and post-production houses, as well
as organizations and individuals creating materials such as corporate and
specialized video and audio presentations. The Company believes that the
proliferation of users of high quality video and audio content is increasing the
demand for products used in the production and presentation of such content. The
Company's high performance graphics systems are used daily by many of the
world's leading broadcast stations to display news flashes, election results,
sports scores, stock market quotations, programming notes and weather
information. The Company's signal management systems interconnect video, audio
and data signals to and from equipment within a studio's control room or edit
suite, as well as to and from signal transmission sites. The Company's control
and automation systems are used to automate the steps used in the management,
editing and distribution of video and audio content.
 
    The creation and delivery of video and audio content has three distinct
stages: production, post-production and distribution. Production involves
shooting video or film, recording sound and creating computer-generated graphics
and other elements for special visual effects. During post-production, video and
audio signals are processed and edited using sophisticated equipment to combine
disparate elements, such as titles, graphics, still and moving images and
computer-generated special effects through techniques such as scene sequencing,
compositing, layering and touch-up. Important attributes of the equipment used
in these processes include real time performance, high signal quality, high
reliability and feature and function upgradeability. Distribution is the
delivery of the finished content. The outlets available for distribution of
video and audio content are proliferating as new cable, satellite and direct
view alternatives supplement traditional broadcast delivery systems. Additional
outlets include video tapes, video discs, CD-ROMs and film. Recently, a
fundamental technological change has been occurring as production, post-
production and distribution facilities, which have historically used an analog
signal format, have been gradually converting, when appropriate, to a digital
signal format. Converting to digital also partially prepares a facility for the
introduction of new digital standards, including Advanced Television ("ATV") and
High Definition Television ("HDTV") which require a digital signal.
 
    The Company believes it is a leading supplier worldwide of character
generators and graphics systems for the high-end graphics market. The Company's
objective is to be the leading provider worldwide of production, post-production
and distribution solutions for video, audio and other data. The Company's
strategy includes the following key elements: (i) maintain and enhance its
leadership position in current markets; (ii) provide upgrades to existing
equipment; (iii) cross sell products to its existing customers; (iv) address
low-end and emerging markets; (v) expand its global presence; (vi) pursue
strategic acquisitions and alliances; and (vii) utilize open platforms. With the
April 1996 acquisition of Pro-Bel Limited, a United Kingdom corporation
("Pro-Bel"), the Company's systems became more comprehensive as signal switching
and routing components were added to its product roster. In addition, in
February 1996, the Company formed a strategic alliance with RT-Set Real Time
Synthesized Entertainment Technology Ltd., an Israeli corporation ("RT-SET"),
which develops virtual reality studio systems for broadcast customers.

                                  RISK FACTORS
 
    AN INVESTMENT IN THE COMMON STOCK OFFERED HEREBY IS SPECULATIVE IN NATURE
AND INVOLVES A HIGH DEGREE OF RISK. IN ADDITION TO THE OTHER INFORMATION
CONTAINED IN THIS PROSPECTUS, THE FOLLOWING FACTORS SHOULD BE CONSIDERED
CAREFULLY IN EVALUATING THE COMPANY AND ITS BUSINESS BEFORE PURCHASING THE
SHARES OF COMMON STOCK OFFERED HEREBY. THIS PROSPECTUS CONTAINS FORWARD-LOOKING
STATEMENTS WITHIN THE MEANING OF SECTION 27A OF THE SECURITIES ACT OF 1933, AS
AMENDED, AND SECTION 21E OF THE SECURITIES EXCHANGE ACT OF 1934, AS AMENDED.
DISCUSSIONS CONTAINING SUCH FORWARD-LOOKING STATEMENTS MAY BE FOUND IN THE
MATERIAL SET FORTH UNDER "PROSPECTUS SUMMARY--THE COMPANY," "RISK FACTORS,"
"MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF
OPERATIONS," "BUSINESS--INDUSTRY BACKGROUND" AND "BUSINESS--STRATEGY" AS WELL AS
THE PROSPECTUS GENERALLY. ACTUAL EVENTS OR RESULTS MAY DIFFER MATERIALLY FROM
THOSE DISCUSSED IN THE FORWARD-LOOKING STATEMENTS AS A RESULT OF VARIOUS
FACTORS, INCLUDING, WITHOUT LIMITATION, THE RISK FACTORS SET FORTH BELOW AND THE
MATTERS SET FORTH IN THE PROSPECTUS GENERALLY.
 
    PRODUCT CONCENTRATION.  The Company's graphics and character generator
products and switching and routing systems have generated substantially all of
the Company's net sales to date, and sales of these products and related
enhancements are expected to continue to account for a majority of the Company's
net sales at least through 1997. Accordingly, the Company's success depends on
continued sales of these products. A decline in demand for or average selling
prices of such products, whether as a result of the introduction of new products
or technologies by others, competition, technological change, inability of the
Company to enhance its products in a timely fashion, or otherwise, could have a
material adverse effect on the Company's business, financial condition and
results of operations. See "Business--Products."
 
    DEPENDENCE ON ANALOG MARKET AND MATURE MARKET SEGMENTS.  Television
broadcasters, cable television operators and other entities involved in the
production and presentation of video and audio content have historically relied
on analog systems for their production, post-production and distribution
systems. The Company believes that such entities are, and over time will
continue, converting their operations to digital systems. If this transition
occurs more rapidly than the Company currently anticipates, demand for certain
of the Company's products, such as routing switchers for analog signals, could
be significantly reduced, and any such reduction could have a material adverse
effect on the Company's business, financial condition and results of operations.
If for any reason the Company is not able to respond to such rapid transition
with appropriate products in a timely fashion or such products do not achieve
market acceptance, it could have a material adverse effect on the Company's
business, financial condition and results of operations. In addition, in certain
geographic regions served by the Company, the traditional broadcast markets have
matured. As a result, the equipment needs of many customers in such markets are
typically characterized by replacements and upgrades rather than expansion. See
"Business--Industry Background" and "--The Chyron Solution."
 
    DEPENDENCE ON EMERGING DIGITAL MARKET.  Television broadcasters, cable
television operators and others involved in the production and presentation of
video and audio content have historically relied on analog technology for many
applications. Digital video and audio technology is still relatively new and
requires a significant initial investment of capital by such users. The
Company's future growth will depend to a significant degree on both the rate at
which such users convert to digital video and audio systems and the rate at
which digital video and audio technology expands to additional market segments.
There can be no assurance that the use of digital video technology will expand
among television broadcasters and cable television operators or into additional
markets. Any failure by the market to accept digital video and audio technology
could have a material adverse effect on the Company's business, financial
condition and results of operations. Recently, a number of companies serving the
digital video and audio markets, including certain competitors of the Company,
have experienced business and financial difficulties, including operating
losses. See "Business--Industry Background."
 
                                       5
<PAGE>
    RISKS ASSOCIATED WITH THE ACQUISITION OF PRO-BEL.  On April 12, 1996, the
Company acquired Pro-Bel, which is based in the United Kingdom. The Company's
future success will depend in part on its ability to integrate Pro-Bel, to
manage the manufacturing operations of such business, to eliminate redundancies
and excess costs and to consolidate the sales and marketing activities, research
and development activities, management information systems and other activities
of Pro-Bel. Although the Company expects it will realize certain business
synergies as a result of the acquisition, such synergies could be affected by
various factors beyond the Company's control, such as future conditions in the
graphics, signal management and control and automation markets and certain
activities of the Company's competitors. As a result, there can be no assurance
that the Company will be able to integrate successfully the operations of
Pro-Bel with those of the Company. The failure to integrate Pro-Bel, increase
the visibility and brand name recognition of Pro-Bel products in the United
States, provide effective local sales and support for Pro-Bel products in the
United States or sell significant amounts of Pro-Bel products in the United
States could have a material adverse effect on the Company's business, financial
condition and results of operations. See "Management's Discussion and Analysis
of Financial Condition and Results of Operations."
 
    HIGHLY COMPETITIVE ENVIRONMENT.  The market for graphics imaging, editing
and animation systems, signal routing systems and media storage systems is
highly competitive and is characterized by rapid technological change and
evolving industry standards. Rapid obsolescence of products, frequent
development of new products and significant price erosion are all features of
the industry in which the Company operates. The Company anticipates increased
competition from both existing companies and new market entrants. The Company is
currently aware of several major and a number of smaller competitors. In the
graphics area, the Company believes its primary competitors are Aston Electronic
Designs Limited, Digital Graphix Inc., Dynatech Corporation, Quantel Inc. and
Scitex Corporation Ltd. In the signal management area, the Company believes its
primary competitors are Dynatech Corporation, Leitch Incorported, Philips
Electronics N.V., Sony Corporation and Tektronix, Inc. In the control and
automation area, the Company believes its primary competitors are Accom, Inc.,
Louth Automation, Philips Electronics N.V., Sony Corporation and Tektronix, Inc.
Many of these companies have significantly greater financial, technical,
manufacturing and marketing resources than the Company. In addition, certain
product categories and market segments, on a region-by-region basis, in which
the Company does or may compete, are dominated by certain vendors. As a result,
the Company's ability to compete in these areas may be limited.
 
    The Company believes that its ability to compete depends on factors both
within and outside its control, including the success and timing of new product
developments introduced by the Company and its competitors, product performance
and price, market presence and customer support. There can be no assurance that
the Company will be able to compete successfully with respect to these factors.
Maintaining any advantage that the Company may have over its competitors will
require continuing investments by the Company in research and development, sales
and marketing and customer service and support. In addition, as the Company
enters new markets, whether through acquisitions, alliances with other companies
or on its own, the Company may encounter distribution channels, technical
requirements and competitive factors that differ from those in the markets in
which it currently operates. There can be no assurance the Company will be able
to compete successfully in these new markets. In addition, increased competition
in any of the Company's current markets could result in price reductions,
reduced margins or loss of market share, any of which could materially and
adversely affect the Company's business, financial condition and results of
operations. There can be no assurance that the Company will be able to compete
successfully against current or future competitors. See "Business--Competition."
 
    RAPID TECHNOLOGICAL CHANGE.  The markets for the Company's products are
characterized by rapidly changing technology, evolving industry standards and
frequent new product introductions and enhancements. Future technological
advances in the television and video industries may result in the availability
of new products or services that could compete with the Company's products or
reduce the cost of existing products or services, any of which could enable the
Company's existing or potential customers to fulfill their needs better and more
cost efficiently than with the Company's products. The Company's future
 
                                       6
<PAGE>
success will depend on its ability to enhance its existing products and to
develop and introduce new products to meet and adapt to changing customer
requirements and emerging technologies. For example, the industry is moving
toward the adoption of a digital standard for ATV and HDTV. The Company does not
currently offer products that fully support ATV and HDTV. Further, customers are
increasingly using non-linear editing systems in addition to, or instead of,
traditional linear editing systems. The Company does not currently offer any
non-linear editing systems. There can be no assurance that the Company will be
successful in enhancing its products or developing, manufacturing or marketing
new products which satisfy these or other customer needs or achieve market
acceptance. In addition, there can be no assurance that services, products or
technologies developed by others will not render the Company's product or
technologies uncompetitive, unmarketable or obsolete, or that announcements of
currently planned or other new product offerings by either the Company or its
competitors will not cause customers to defer or fail to purchase existing
Company solutions. Rapid technological change also increases the risk to the
Company of possible excess or obsolete inventory. Furthermore, the trend toward
the use of open systems may cause price erosion in the Company's products,
create opportunities for new competitors, allow existing competitors enhanced
opportunities and limit the sale of the Company's proprietary systems. The
failure of the Company to respond to rapidly changing technologies could have a
material adverse effect on the Company's business, financial condition and
results of operations. See "Business--Products" and "--Research and
Development."
 
    RISK OF NEW PRODUCT INTRODUCTIONS.  The Company's future success requires
that it develop and market new products and enhancements that achieve
significant market acceptance. There can be no assurance that the Company will
not experience difficulties that could delay or prevent the successful
development, introduction and marketing of new products and enhancements, that
its new products and enhancements will adequately meet the requirements of the
marketplace and achieve market acceptance. Announcements of currently planned or
other new products or enhancements may cause customers to defer purchasing
existing Company products. Moreover, there can be no assurance that errors or
failures will not be found in the Company's products or, if discovered,
successfully corrected in a timely manner. Such errors or failures could cause
delays in product introductions and shipments or require design modifications
that could adversely affect the Company's competitive position. Any inability to
develop on a timely basis new products and enhancements, to correct errors, or
to achieve market acceptance and manage product transitions and inventory
levels, could have a material adverse effect on the Company's business,
financial condition and results of operations. See "Business--Products" and
"--Research and Development."
 
    RISKS ASSOCIATED WITH EXPANSION INTO NEW MARKETS.  To date, a majority of
the Company's products have been sold in the United States and the United
Kingdom. The Company's success, however, depends in part on its expansion into
new geographic markets and new market segments. There can be no assurance that
the Company will be successful in marketing and selling its products to
customers in new markets. Customers in such markets may also have unique product
requirements, such as support of foreign languages or special features, which
may be difficult and expensive for the Company to develop and support. In
addition, competitive suppliers may have strong or dominant positions in such
markets. Any inability of the Company to penetrate these new markets could have
a material adverse effect on the Company's growth. See "Business--Products."
 
    RISKS ASSOCIATED WITH THE COMPANY'S ACQUISITION AND ALLIANCE STRATEGY.  In
pursuit of its strategic objective to expand through acquisitions of and
alliances with complementary businesses, the Company recently acquired Pro-Bel
and invested in and formed a strategic alliance with RT-SET. In the past, the
Company has also acquired other businesses, some of which subsequently have been
restructured and discontinued. The Company continually evaluates conditions for
acquisitions, strategic investments and alliances. The Company's acquisition and
alliance strategy entails the potential risks inherent in assessing the value,
strengths, weaknesses, liabilities and financial performance of acquisition and
alliance candidates and in integrating the operations of acquired businesses
with those of the Company. There can be no
 
                                       7
<PAGE>
assurance, however, that acquisition or alliance opportunities will continue to
be available, that the Company will have access to the capital required to
finance potential acquisitions and alliances, that the Company will continue to
acquire businesses or enter into alliance agreements or that any business
acquired or alliance entered into will be integrated successfully or prove
profitable. Moreover, once an acquisition is completed, there can be no
assurance that acquired products, technologies or businesses will be effectively
assimilated into the Company's business or product offerings, that the Company
will be effectively able to derive the benefits of or continue to maintain the
brand name recognition of acquired companies or products, that the Company will
be able to effectively manage product transitions and inventory levels or that
the Company will be able to retain key employees of acquired companies. In
addition, the Company may incur significant expenses in completing any such
acquisitions and investments and in supporting the acquired products,
technologies or businesses. Acquisitions may also consume certain management
resources, which may temporarily divert management efforts from the day-to-day
business of the Company. There can be no assurance that any acquired products,
technologies or businesses will contribute to the Company's revenues or earnings
to any material extent.
 
    The Company has made and expects it will continue to make acquisitions,
strategic investments and alliances outside of the United States. While these
activities may provide important opportunities for the Company to offer its
products and services internationally, they also entail the risks associated
with conducting business internationally, including the risk of currency
exchange rate fluctuations and social, political and economic instability. See
"Business--Strategy."
 
    ABILITY TO MANAGE GROWTH AND EXPANSION.  The Company plans to continue to
expand its operations. The management of the Company's growth, if any, will
require continued expansion of the Company's operational and financial control
systems, as well as an increase in the Company's research and development and
marketing and sales capabilities, all of which could place a significant strain
on the Company's resources. The Company's inability to manage its growth
effectively could have a material adverse effect on its business, financial
condition and results of operations. The Company's ability to compete
effectively and to manage future expansion of its operations, if any, will
require the Company to increase the number of its employees. The Company is
dependent to a substantial degree upon its marketing and sales and research and
development personnel and its technical, service and support staff. There is
considerable competition for the services of such personnel. There can be no
assurance that the Company will be able either to retain its present personnel
or to acquire additional qualified personnel as and when needed. See
"Business--Strategy."
 
    SEASONALITY.  The Company's business has typically been seasonal with more
orders usually being received and greater revenues being recognized in the
fourth quarter than in each of the first, second or third quarters,
respectively. The Company believes that the concentration of order placements in
specific quarterly periods is due to customers' buying patterns and budgeting
cycles. In addition, the Company's business is also affected by broadcast events
in the television industry such as the Olympics and national and local
elections. The Company anticipates that these patterns will continue in the
future. As a result, the Company's results of operations have in the past and
likely will in the future vary seasonally in accordance with such purchasing
activity. Due to the relatively fixed nature of certain of the Company's costs
throughout each quarterly period, including personnel and facilities costs, the
decline of revenues in any quarter typically results in lower profitability in
that period and, in such event, the price of the Company's Common Stock could be
materially adversely affected. See "Management's Discussion and Analysis of
Financial Condition and Results of Operations--Quarterly Results of Operations."
 
    FLUCTUATIONS IN QUARTERLY OPERATING RESULTS.  The Company's quarterly
operating results have in the past varied and in the future will be affected by
factors such as: (i) the timing and recognition of revenue from significant
orders; (ii) the seasonality of the placement of customer orders; (iii) the
success of the Company's products; (iv) increased competition; (v) changes in
the Company's pricing policies or those of
 
                                       8
<PAGE>
its competitors; (vi) the financial stability of major customers; (vii) new
product introductions or enhancements by competitors; (viii) delays in the
introduction of products or product enhancements by the Company; (ix) customer
order deferrals in anticipation of upgrades and new products; (x) the ability to
access a sufficient supply of sole source and third-party components; (xi) the
quality and market acceptance of new products; (xii) the timing and nature of
selling and marketing expenses (such as trade shows and other promotions);
(xiii) personnel changes; (xiv) the lengthy sales cycle associated with the
Company's switching and routing systems and certain other products; (xv) high
per unit list prices for the Company's equipment, thereby posing significant
barriers to the purchase of equipment for potential customers; and (xvi)
economic conditions affecting the Company's customers. In addition, the Company
typically makes a significant portion of its quarterly shipments in the last
month of a quarter, frequently in the last weeks or even days of a quarter. As a
result, any delay, interruption or inability to ship products could have a
significant impact on the Company's quarterly business, financial condition and
results of operations. Any significant cancellation or deferral of purchases of
the Company's products could have a material adverse effect on the Company's
business, financial condition and results of operations in any particular
quarter and, to the extent significant sales occur in an earlier quarter than
expected, operating results for subsequent quarters may be adversely affected.
The Company's expense levels are based, in part, on its expectations as to
future revenues and the Company may be unable to adjust spending in a timely
manner to compensate for any revenue shortfall. If revenues are below
expectations, operating results are likely to be adversely affected and net
income may be disproportionately affected because a significant portion of the
Company's expenses do not vary with revenues.
 
    Because of these factors, the Company believes that period-to-period
comparisons of its results of operations are not necessarily meaningful and
should not be relied upon as indications of future performance. Due to all of
the foregoing factors, in some future quarter the Company's operating results
may be below the expectations of public market analysts and investors. In such
event, the price of the Company's Common Stock would likely be materially and
adversely affected. See "Selected Consolidated Financial Data" and "Management's
Discussion and Analysis of Financial Condition and Results of
Operations--Quarterly Results of Operations."
 
    DEPENDENCE ON PROPRIETARY TECHNOLOGY; RISKS OF INFRINGEMENT.  The Company's
success depends, in part, upon its ability to protect its proprietary software
technology and operate without infringing the rights of others. It relies on a
combination of patent, trademark, copyright and trade secret laws together with
non-disclosure and confidentiality agreements to establish and protect its
intellectual property rights in its technology. There can be no assurance that
the steps taken by the Company regarding its proprietary technology will be
sufficient to deter misappropriation or that the Company's competitors will not
independently develop technologies that are substantially equivalent or superior
to the Company's technologies. In addition, the laws of certain countries in
which the Company's products are or may be distributed do not protect the
Company's products and intellectual rights to the extent of the laws of the
United States.
 
    In the systems and software industries, companies receive notices from time
to time alleging infringement of patents, copyrights or other intellectual
property rights of others. While the Company is not currently involved in any
pending intellectual property litigation, the Company has been and may from time
to time continue to be notified of claims that it may be infringing patents,
copyrights or other intellectual property rights owned by third parties. There
can be no assurance that these or other companies will not in the future pursue
claims against the Company with respect to the alleged infringement of patents,
copyrights or other intellectual property rights owned by third parties. In
addition, litigation may be necessary to protect the Company's intellectual
property rights and trade secrets, to determine the validity of and scope of the
proprietary rights of others or to defend against third-party claims of
invalidity. Any litigation could result in substantial costs and diversion of
resources and could have a material adverse effect on the Company's business,
financial condition and results of operations. See "Business--Patents and
Proprietary Rights."
 
                                       9
<PAGE>
    RISKS ASSOCIATED WITH INTERNATIONAL OPERATIONS.  International sales have
represented a significant and growing portion of the Company's sales. The
Company's international operations are subject to a number of special risks,
including currency exchange rate fluctuations, trade barriers, exchange
controls, credit risk, length of payment terms, political risks and risks of
increases in duties, taxes and governmental royalties, as well as changes in
laws and policies governing operations of foreign-based companies. Currently,
the Company's sales are made in either United States dollars or United Kingdom
pounds sterling. Accordingly, the Company may be exposed to risks of currency
fluctuations. The Company has not and does not currently intend to engage in any
currency hedging activities. See "Management's Discussion and Analysis of
Financial Condition and Results of Operations."
 
    LIMITED HISTORY OF NEW MANAGEMENT.  The Company's current Chairman and Chief
Executive Officer was appointed in July 1995, following a change in control of
the Company pursuant to the sale by Pesa Inc. ("Pesa") of 19,804,910 shares of
Common Stock and the sale by Sepa Technologies Ltd., Co. ("Sepa"), an affiliate
of Pesa, of 1,666,666 shares of Common Stock to the current principal
shareholders of the Company. In 1990, the Company sought protection under
Chapter 11 of the United States Bankruptcy Code ("Chapter 11"). The Company
subsequently emerged from Chapter 11 in December 1991 and underwent a
restructuring of its West Coast operations in 1994 to eliminate unprofitable
product lines. The Company's future success depends in large part upon the
ability of the Company's new management to develop and manage the Company's
business and growth, including the newly acquired Pro-Bel. Key members of new
management are located in both the United Kingdom and the United States. New
management's limited history managing the Company may make it more difficult for
potential investors to evaluate the likelihood of management's ability to manage
the Company successfully. See "The Company," "Management's Discussion and
Analysis of Financial Condition and Results of Operations" and "Management."
 
    DEPENDENCE ON KEY PERSONNEL.  The Company's future performance depends to a
significant degree upon the continued contributions of members of the Company's
senior management personnel and on its ability to attract, motivate and retain
highly qualified employees. Competition for highly qualified employees is
intense, and the process of identifying and successfully recruiting personnel
with the combination of skills and attributes required to execute the Company's
strategies is often lengthy. Accordingly, the loss of the service of any key
personnel could have a material adverse effect on the Company's business,
financial condition and results of operations. There can be no assurance that
the Company will be successful in retaining its key technical and management
personnel or in attracting and retaining the personnel it requires for continued
growth. See "Business--Employees" and "Management."
 
    DEPENDENCE ON KEY SUPPLIERS AND THIRD-PARTY MANUFACTURERS.  Certain key
components of the Company's products are currently purchased from a single or a
few key suppliers. The inability to obtain sufficient key components as
required, or to develop alternative sources if and as required in the future,
could result in delays or reductions in product shipments which, in turn, could
have a material adverse effect on the Company's business, financial condition
and results of operations. Moreover, the Company relies on a limited number of
third parties who manufacture all of the hardware components and sub-assemblies
utilized in certain of the Company's products, including its graphic systems.
While to date there has been suitable third-party manufacturing capacity readily
available at acceptable quality levels, there can be no assurance that such
manufacturers will be able to meet the Company's future volume or quality
requirements or that such services will continue to be available to the Company
at favorable prices. Any financial, operational, production or quality assurance
difficulties experienced by such third-party manufacturers that result in a
reduction or interruption in supply to the Company could have a material adverse
effect on the Company's business, financial condition and results of operations.
See "Business-- Manufacturing."
 
    RESTRICTIONS IMPOSED BY INDEBTEDNESS.  In connection with the Company's
acquisition of Pro-Bel on April 12, 1996, the Company entered into a loan
agreement and credit facility which are secured by the
 
                                       10
<PAGE>
Company's assets and contain a number of significant covenants that, among other
things, will restrict the ability of the Company and its subsidiaries to dispose
of assets, incur additional indebtedness, repay other indebtedness, pay
dividends, make certain investments or acquisitions, repurchase or redeem
capital stock, engage in mergers or consolidations, or engage in certain
transactions with subsidiaries and affiliates and otherwise restrict certain
corporate activities. There can be no assurance that such restrictions will not
adversely effect the Company's ability to finance its future operations or
capital needs or engage in other business activities that may be in the best
interest of the Company. In addition, the loan agreement and credit facility
require the Company to maintain compliance with certain financial ratios. The
ability of the Company to comply with such ratios may be affected by events
beyond the Company's control. A breach of any of these covenants or the
inability of the Company to comply with the covenants regarding financial ratios
could result in an event of default under the loan agreement and credit
facility. In the event of any such default, the lender could elect to declare
all borrowings outstanding thereunder, together with accrued interest and other
fees, to be due and payable and to require the Company to apply all of its
available cash to repay such borrowings. If the Company was unable to repay any
such borrowings when due, the lender could proceed against its collateral.
 
    In addition, Pro-Bel has a separate loan facility which is secured by its
assets and is repayable on demand. This facility restricts Pro-Bel and its
subsidiaries from, among other things, obtaining additional financing or making
any equity or debt investments. The Company intends to enter into a new loan
facility with the same lender which will replace the current one and contain
similar restrictions.
 
    REGULATION OF TELECOMMUNICATIONS AND TELEVISION INDUSTRIES.  The
telecommunications and television industries are subject to extensive regulation
in the United States and other countries. The Company's business is dependent
upon the continued growth of such industries in the United States and
internationally. Although recent legislation has lowered the legal barriers to
entry for telecommunications companies into the United States' multichannel
television market, there can be no assurance that such telecommunications
companies will successfully enter this or related markets. Moreover, the growth
of the Company's business internationally is dependent in part on similar
deregulation of the telecommunications industry abroad and there can be no
assurance that such deregulation will occur. Television operators are subject to
extensive government regulation by the Federal Communications Commission and
other federal and state regulatory agencies. These regulations could have the
effect of limiting capital expenditures by television operators and thus could
have a material adverse effect on the Company's business, financial condition
and results of operations. The enactment by federal, state or international
governments of new laws or regulations, changes in the interpretation of
existing regulations or a reversal of the trend toward deregulation in these
industries could adversely affect the Company's customers, and thereby
materially adversely affect the Company's business, financial condition and
results of operations. See "Business-- Industry Background."
 
    CONTROL BY PRINCIPAL SHAREHOLDERS, OFFICERS AND DIRECTORS.  Upon the
completion of this offering, the Company's officers, directors and 5%
shareholders (and their affiliates) will, in the aggregate, beneficially own
approximately 58.4% of the Company's outstanding Common Stock and Mr. Michael I.
Wellesley-Wesley, Chairman of the Board of Directors and Chief Executive
Officer, will beneficially own approximately 20.3%. As a result, such persons,
acting together, will have the ability to control the vote on matters submitted
to shareholders of the Company for approval (including election of directors and
any merger, consolidation or sale of all or substantially all of the Company's
assets) and to control the management and affairs of the Company. Accordingly,
such concentration of ownership may have the effect of delaying, deferring or
preventing a change in control of the Company, impede a merger, consolidation,
takeover or other business combination involving the Company or discourage a
potential acquiror from making a tender offer or otherwise attempting to obtain
control of the Company. See "Management" and "Principal and Selling
Shareholders."

<PAGE>
    BROAD DISCRETION AS TO USE OF PROCEEDS.  The Company intends to use
approximately $12.4 million of the net proceeds from this offering to repay
indebtedness and the remaining net proceeds for working capital and other
general corporate purposes, including possible acquisitions, increased marketing
and such other purposes as management may determine in its sole discretion. The
Company's management has reserved the right to reallocate a portion of the net
proceeds and there can be no assurance that the proceeds will yield a
significant return. See "Use of Proceeds."
 
    ABSENCE OF DIVIDENDS.  The Company has not paid cash dividends on its Common
Stock since November 27, 1989 and does not anticipate paying any cash dividends
in the foreseeable future. The Company intends to retain any earnings for use in
its business. The decision to pay dividends in the future will be at the
discretion of the Board of Directors and is subject to certain restrictions
under its loan agreement and credit facility. See "Price Range of Common Stock"
and "Dividend Policy."
 
    POTENTIAL DILUTION RELATED TO RT-SET.  Pursuant to an alliance agreement
with RT-SET, the Company has the option to acquire up to a 51% interest in
RT-SET in exchange for Common Stock. The value of the shares of Common Stock
shall be calculated by taking the average closing price of shares of Common
Stock traded on the New York Stock Exchange for the 20 trading days immediately
prior to the date the Company sends a notice to RT-SET that it is exercising its
option. Although such shares of Common Stock shall not be registered with the
Commission, they will be subject to piggyback registration rights commencing 12
months after the date of closing of the exercise of the option. If the Company
exercises the option and issues Common Stock, purchasers of Common Stock offered
hereby could suffer dilution in the net tangible book value per share of the
Common Stock offered hereby. See "Management's Discussion and Analysis of
Financial Condition and Results of Operations."
 
    ISSUANCE OF PREFERRED STOCK; POSSIBLE DELAY OR PREVENTION OF CORPORATE
TAKE-OVER.  The Company is authorized to issue up to 1,000,000 shares of
preferred stock, par value $1.00 per share, without further stockholder
approval. The Board of Directors is authorized to determine, without any further
action by the holders of the Common Stock, the rights, preferences and
limitations of such preferred shares. Should the Board of Directors elect to
exercise such authority, the rights and privileges of holders of Common Stock
could be made subject to the rights and privileges of any such series of
preferred stock. The issuance of a series of preferred stock of the Company
could delay, defer or prevent a change in control of the Company without further
shareholder action and could adversely affect the market price of the shares of
Common Stock offered hereby. No shares of preferred stock are currently
outstanding. See "Description of Capital Stock."
 
    SHARES ELIGIBLE FOR FUTURE SALE; POSSIBLE ADVERSE EFFECTS ON FUTURE MARKET
PRICE.  Sales of a substantial number of shares of Common Stock following
completion of the offering could adversely affect prevailing market prices and
could impair the Company's future ability to raise capital through the sale of
its equity securities. Upon completion of this offering, the Company will have
37,632,413 shares of Common Stock outstanding. Of these shares of Common Stock,
7,650,000 shares will be freely tradeable without restriction under the
Securities Act (except by "affiliates" of the Company) of the remaining
32,382,413 outstanding shares of Common Stock, 11,584,643 shares (the
"Restricted Shares") will be "restricted securities" as defined in Rule 144
promulgated under the Securities Act ("Rule 144"). An additional 1,433,333
shares currently subject to contractual limitations on sale or transfer will
become eligible for sale to the public on July 25, 1997. The Company, its
officers and directors and the Selling Shareholders will be subject to lock-up
arrangements (the "Lock-Up") under which they have agreed not to offer, sell,
contract to sell, pledge or grant any option to purchase or otherwise dispose of
12,562,333 shares of Common Stock for a period of 180 days after the date of
this Prospectus without the prior written consent of Oppenheimer & Co., Inc.
After such period, such shares of Common Stock may be sold only pursuant to an
effective registration statement under the Securities Act, or pursuant to an
exemption therefrom, including exemptions to the provisions of Rule 144.
 
                                       12
<PAGE>
    Of the 11,524,643 Restricted Shares, up to 5,719,733 Restricted Shares will
become eligible for sale pursuant to Rule 144 during 1998; up to 3,000,000
Restricted Shares will become eligible for sale pursuant to Rule 144 during
1999; up to 2,000,000 Restricted Shares will become eligible for sale pursuant
to Rule 144 during 2000 and up to 804,910 Restricted Shares will become eligible
for sale pursuant to Rule 144 during 2001. See "Shares Eligible for Future
Sale."
 
    The holders of 24,471,544 shares, including the Restricted Shares, may,
subject to the Lock-Up, by exercising demand registration rights, require the
Company, beginning 90 days after the effective date of this Prospectus (the
"Effective Date"), to file a registration statement under the Securities Act
with respect to their Restricted Shares, and the Company is required to use its
best efforts to effect such registration, subject to certain conditions and
limitations. Holders of an additional 1,048,735 Restricted Shares will become
entitled to demand registration rights during July 1997. If such holders, by
exercising such registration rights, cause a large number of shares to be sold
in the public market, the market price of the Common Stock could be adversely
affected. See "Description of Capital Stock--Registration Rights."
 
    STOCK PRICE VOLATILITY.  The trading price of the Common Stock has been and
may continue to be subject to fluctuations in response to quarter-to-quarter
variations in operating results, changes in earnings estimates by analysts,
general conditions in the television broadcasting and related industries,
announcements of technological innovations or new products introduced by the
Company or its competitors and other events or factors. The stock market in
general, and the shares of technology companies in particular, have experienced
extreme price fluctuations in recent years. This volatility has had a
substantial impact on the market prices of securities issued by many companies
for reasons unrelated to the operating performance of the companies affected.
These broad market fluctuations may adversely affect the market price of the
Common Stock.

                                  THE COMPANY
 
    The Company was incorporated under the laws of the State of New York on
April 8, 1966 under the name The Computer Exchange, Inc., which was changed to
the present name on November 28, 1975. The Company's principal executive offices
are located at 5 Hub Drive, Melville, New York 11747 and its telephone number is
(516) 845-2000. Its executive offices in the United Kingdom are located at
Danehill, Lower Earley, Reading, Berks RG6 4PB and its telephone number is
44-1734-86-61-23.
 
    On September 17, 1990, the Company and its subsidiaries sought relief under
Chapter 11 of the United States Bankruptcy Code. On December 27, 1991, the
Company emerged from bankruptcy. Pursuant to its plan of reorganization, the
Company issued to its banks shares of Common Stock which represented 81% of the
voting power and beneficial ownership of all the issued and outstanding Common
Stock on a fully diluted basis. Such shares of Common Stock were then purchased
from the banks by Pesa. Subsequently, Pesa transferred 4,666,666 shares of
Common Stock to its affiliate Sepa.
 
    In May 1995, CC Acquisition Company A, L.L.C., a Delaware limited liability
company ("CCA"), an entity affiliated with Mr. Allan R. Tessler and Mr. Michael
I. Wellesley-Wesley, acquired 3,333,333 shares of Common Stock from Pesa. In
July 1995, control of the Company was transferred through the sale of an
additional 18,138,244 shares of Common Stock by Pesa and Sepa to (i) CC
Acquisition Company B, L.L.C., a Delaware limited liability company ("CCB"), an
entity affiliated with Mr. Tessler and Mr. Wellesley-Wesley; (ii) various funds
managed by Weiss, Peck & Greer, L.L.C. ("Weiss, Peck & Greer"); and (iii)
Westpool Investment Trust plc ("Westpool") (Weiss, Peck & Greer and Westpool are
collectively referred to as the "WPG/Westpool Investment Group"). In addition,
Sepa transferred the voting control over 3,000,000 shares of Common Stock to
these entities. CCA and CCB together beneficially own 8,455,297 shares of Common
Stock. The WPG/Westpool Investor Group beneficially owns in the aggregate
15,768,632 shares. As a result of the new investor groups obtaining control, a
new executive management team was put in place, a new Board of Directors was
elected and a new business strategy was adopted. In July 1995, Mr.
Wellesley-Wesley became the Chief Executive Officer and Chairman of the Board of
Directors and Mr. Isaac Hersly was promoted to President and Chief Operating
Officer.
 
                                USE OF PROCEEDS
 
    The net proceeds to the Company from the sale of the shares of Common Stock
offered by the Company are estimated to be $   million, after deducting the
underwriting discount and the estimated offering expenses payable by the
Company. The Company expects to use approximately $12.4 million of the net
proceeds for the repayment of indebtedness (including accrued interest thereon)
which bears interest at rates ranging from 7.75% to 8.25% per annum and matures
through April 16, 2000. The outstanding borrowings under these facilities were
incurred to finance the Pro-Bel acquisition and to replace the Company's then
existing working capital loan. The balance of the net proceeds from this
offering will be used for general corporate purposes, possible acquisitions and
strategic alliances, marketing, working capital and other general corporate
purposes. As part of its business strategy, the Company continually evaluates
potential acquisitions of businesses, products and technologies as well as
strategic alliances. Accordingly, a portion of the net proceeds may be used for
the acquisition of complementary businesses, technologies or products as well as
strategic alliances. The Company currently has no understanding, commitment,
agreement or present intention with respect to any particular acquisition or
strategic alliance. Pending such uses, the Company intends to invest such funds
in short-term, high quality investment grade, interest-bearing securities of the
United States.

notes thereto and "Management's Discussion and Analysis of Financial Condition
and Results of Operations" included elsewhere in this Prospectus. The statement
of operations data for the years ended December 31, 1993, 1994 and 1995 and the
balance sheet data as of December 31, 1994 and 1995 are derived from, and
qualified by reference to, the Company's consolidated financial statements
audited by Price Waterhouse LLP for the year ended December 31, 1995 and by
Ernst & Young LLP for the years ended December 31, 1994 and 1993 included
elsewhere in this Prospectus (except for the balance sheet data as of December
31, 1993 which has been derived from audited financial statements not included
herein). The statement of operations data and the balance sheet data as of and
for the year ended December 31, 1992 have been derived from audited consolidated
financial statements not included herein. The statement of operations data for
the nine month periods ended September 30, 1995 and 1996 and the balance sheet
data at September 30, 1995 are derived from, and qualified by reference to,
unaudited interim financial statements contained elsewhere herein. Management
believes that all normal recurring adjustments necessary for a fair presentation
have been made in such interim periods. The results of operations for the most
recent interim period, however, are not necessarily indicative of the Company's
financial results for the entire current fiscal year.

          MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION
                           AND RESULTS OF OPERATIONS
 
    THE FOLLOWING MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION
AND RESULTS OF OPERATIONS CONTAINS FORWARD-LOOKING STATEMENTS WHICH INVOLVE
RISKS AND UNCERTAINTIES. THE COMPANY'S ACTUAL RESULTS COULD DIFFER MATERIALLY
FROM THOSE ANTICIPATED IN THESE FORWARD-LOOKING STATEMENTS AS A RESULT OF
CERTAIN FACTORS, INCLUDING THOSE SET FORTH UNDER "RISK FACTORS" AND ELSEWHERE IN
THIS PROSPECTUS.
 
OVERVIEW
 
    The Company develops, manufactures, markets and supports a broad range of
equipment, software and systems that facilitate the production and enhance the
presentation of live and pre-recorded video, audio and other data. The Company
introduced the iNFiNiT!, its flagship product, in late 1990. Subsequently, the
Company has introduced a broad range of graphics products such as the MAX!> and
MAXINE!, CODI, LIBERTY, WiNFiNiT! and IMAGESTOR!. These products superimpose
text, logos and other graphics onto a primary video image or create an
independent image to be televised by itself. The Company expects that revenue
from its current graphics and character generator systems will continue to
constitute a substantial percentage of its net sales in the near future. The
Company's Pro-Bel signal management systems interconnect video, audio and data
signals to and from equipment within a studio's control room or edit suite, as
well as to and from signal transmission sites. The Company expects that sales of
switching and routing systems will also be a significant contributor to net
sales in the coming years.
 
    The Company's net sales have increased from $29.7 million in 1992 to $54.0
million in 1995, while gross profit has increased from $17.2 million in 1992 to
$31.2 million in 1995 and $30.0 million in the nine months ended September 30,
1996. During the same periods, net income was $1.0 million, $7.5 million, and
$5.6 million, respectively.
 
    The Company was incorporated under the laws of the State of New York on
April 8, 1966. The Company filed for Chapter 11 protection in September 1990 and
emerged from Chapter 11 in December 1991. See "The Company." In 1994, the
Company restructured its West Coast operations, resulting in a charge of
approximately $12.7 million. In 1995, the new investor group obtained control, a
new executive management team was put in place, a new Board of Directors was
elected and a new business strategy was adopted.
 
    The Company's strategy includes the following key elements: (i) maintain and
enhance its leadership position in current markets; (ii) provide upgrades to
existing equipment; (iii) cross sell products to its existing customers; (iv)
address low-end and emerging markets; (v) expand its global presence; (vi)
pursue strategic acquisitions and alliances; and (vii) utilize open platforms.
The Company intends to continue to serve its worldwide customer base by
introducing products which address the requirement to improve the production and
presentation of video, audio and other data. The Company also intends to
continue to upgrade its current high performance systems, invest in the
development of new options and enhancements for its products and provide
complete system solutions to its customers.
 
ACQUISITION OF PRO-BEL
 
    On April 12, 1996, the Company acquired Pro-Bel, located in Reading, United
Kingdom. Pro-Bel manufactures and distributes video signal and switching
equipment and systems. The aggregate consideration consisted of $6.9 million in
cash, $5.3 million in two-year promissory notes and 1,048,735 restricted shares
of Common Stock valued at $6.9 million.
 
    The acquisition of Pro-Bel was accounted for as a purchase. Accordingly, the
cost was allocated to the net assets acquired based upon their estimated fair
value. The excess of cost over the estimated fair value of the net assets
acquired amounted to $7.5 million, which is being amortized over 12 years using
the straight-line method.

    The consolidated financial statements of the Company at and for the nine
months ended September 30, 1996 include the accounts of the Company and its
wholly owned subsidiaries, Pro-Bel and subsidiaries, since their acquisition on
April 12, 1996, and Digital Services Corporation, which is presently inactive.
 
INVESTMENT IN RT-SET
 
    On February 29, 1996, the Company purchased a 19% interest in RT-SET, which
develops, markets and sells real time virtual studio set software and
proprietary communications hardware. The Company purchased shares of RT-SET
Convertible Preferred Stock in exchange for 800,000 restricted shares of Common
Stock. In addition, the Company was granted certain call option rights which, if
and when exercised, allows the Company to purchase up to a 51% interest in
RT-SET in exchange for the issuance of additional shares of Common Stock. In
accordance with the purchase agreement, the 800,000 shares of Common Stock were
to be held in escrow and released in two tranches, subject to certain
conditions. One-third of such shares was released from escrow in June 1996 and
the remainder will be released upon a public offering of RT-SET's equity. Prior
to any public offering by RT-SET, the Company has the right to recover the
remaining two-thirds of its shares held in escrow in exchange for its interest
in RT-SET. The transaction has been recorded as the purchase of a right to
acquire a 19% interest in RT-SET. RT-SET shall retain the voting rights with
respect to the escrowed shares while such shares are held by the escrow agent.
The acquisition was recorded at the estimated fair value of the restricted
shares of Common Stock released from escrow. See "Business--RT-SET
Relationship."

NINE MONTHS ENDED SEPTEMBER 30, 1996 COMPARED TO NINE MONTHS ENDED SEPTEMBER 30,
  1995
 
    The Company's net sales consist of product sales, upgrades and enhancements
and rental income as well as customer service revenue.
 
    NET SALES.  Net sales increased 47.3% to $56.9 million for the nine months
ended September 30, 1996 from $38.6 million for the nine months ended September
30, 1995. This increase was primarily attributable to the inclusion of Pro-Bel's
sales, while sales of Chyron's graphic products also showed continued growth.
 
    GROSS PROFIT.  Gross profit increased to $30.0 million for the nine months
ended September 30, 1996 from $21.7 million for the nine months ended September
30, 1995. This increase was primarily attributable to the 47.3% increase in net
sales. Gross margin as a percentage of net sales decreased to 52.7% for the nine
months ended September 30, 1996 from 56.2% for the nine months ended September
30, 1995. This decrease was caused primarily by the inclusion since April 1996
of net sales from Pro-Bel products, which historically have lower margins. The
gross margin for the Chyron product lines decreased slightly as a result of the
product mix for the period.
 
    SELLING, GENERAL AND ADMINISTRATIVE EXPENSES.  Selling, general and
administrative expenses increased 29.3% to $16.4 million for the nine months
ended September 30, 1996 from $12.6 million in the nine months ended September
30, 1995. As a percentage of net sales, selling, general and administrative
expenses decreased to 28.7% for the nine months ended September 30, 1996 from
32.8% for the nine months ended September 30, 1995. The dollar increase was
primarily due to the inclusion of Pro-Bel's operations since April, 1996 and the
accounting for the acquisition under the purchase method resulting in goodwill
amortization and increased depreciation, as well as increased costs as a direct
result of increased sales volume. The decrease as a percentage of net sales was
also affected by the incurrence in 1995 of $443,000 of one-time legal and
investment banking fees and $390,000 of severance costs for former management.
 
    RESEARCH AND DEVELOPMENT EXPENSES.  Research and development expenses
increased 22.4% to $3.8 million for the nine months ended September 30, 1996
from $3.1 million for the nine months ended September 30, 1995. This increase
was primarily due to the inclusion of Pro-Bel's research and development
expenditures since April 1996. Research and development expenses related to
Chyron's product lines decreased for the period due to an increase of $415,000
in amounts capitalized and due to an increased percentage of research and
development undertaken internally instead of by outside consultants.
 
    INTEREST EXPENSE, NET.  Interest expense, net 94.2% to $872,000 for the nine
months ended September 30, 1996 from $449,000 for the nine months ended
September 30, 1995. In conjunction with the Pro-Bel acquisition, the Company
entered into various agreements with a bank, issued promissory notes to the
shareholders of Pro-Bel, and assumed Pro-Bel's existing bank debt, all of which
led to an increase in interest expense for the period.
 
    INCOME BEFORE PROVISION FOR INCOME TAXES.  Income before provision for
income taxes improved 68.1% to $9.0 million for the nine months ended September
30, 1996 from $5.4 million for the nine months ended September 30, 1995,
primarily due to the improved operating income of Chyron coupled with the
addition of Pro-Bel.
 
    INCOME TAXES/EQUIVALENT PROVISION.  Income taxes/equivalent provision
increased 130.5% to $3.4 million for the nine months ended September 30, 1996
from $1.5 million for the nine months ended September 30, 1995 primarily as a
result of the income tax benefit realized during 1995 as a result of the 1994
West Coast restructuring. This increase was also due to increased income before
income taxes for the 1996 period.

YEAR ENDED DECEMBER 31, 1995 COMPARED TO THE YEAR ENDED DECEMBER 31, 1994
 
    NET SALES.  Net sales increased 26.2% to $54.0 million in 1995 from $42.8
million in 1994. This increase was primarily due to increased sales of the
Company's character generator lines. The iNFiNiT! product line showed the
largest dollar growth at $6.4 million, or 41%, with the MAX!> line showing the
largest percentage growth at 65%, or $4.7 million. Increases in net sales also
reflect growth in the Company's MAXINE! product line, sales of which grew by
$2.4 million, or 39%, over the prior year. The growth in sales was seen both
domestically and abroad. These increases were partially offset by the lack of
sales from products discontinued in connection with the West Coast
restructuring.
 
    GROSS PROFIT.  Gross profit increased 30.9% to $31.2 million in 1995 from
$23.9 million in 1994. This increase was primarily due to the 26.2% increase in
net sales. Gross margin as a percentage of net sales increased to 58% in 1995
from 56% in 1994 mainly due to increased manufacturing efficiencies and
management's cost reduction efforts.
 
    SELLING, GENERAL AND ADMINISTRATIVE EXPENSES.  Selling, general and
administrative expenses increased 19.3% to $17.0 million in 1995 from $14.3
million in 1994. This increase was primarily due to (i) legal and investment
banking fees of $443,000 incurred with respect to the undertakings of the
Special Transaction Committee of the Board of Directors, which had been
appointed in connection with the potential change in control of the Company,
(ii) the accrual of $430,000 of severance payments for former management and
(iii) increases due to increases in costs related to the 26.2% increase in net
sales. These increases were offset by costs cutting measures instituted by the
Company as part of the West Coast restructuring in the prior year resulting in a
decrease in selling, general and administrative expenses as a percentage of net
sales to 31.7% in 1995 from 33.5% in 1994.
 
    RESEARCH AND DEVELOPMENT EXPENSES.  Research and development expenses
decreased by $58,000 to $4.1 million in 1995. This decrease was primarily due to
benefits recognized as part of the Company's West Coast restructuring in the
third quarter of 1994, which eliminated costs related to the Company's
unprofitable product lines. Exclusive of 1994 costs related to unprofitable
product lines, research and development expenses increased by $359,000 in 1995.
This increase was primarily due to additional expenditures for new product
development to address emerging markets targeted by the Company as well as the
development of new features for the Company's existing products. Research and
development expenses includes the amortization of software development costs,
which increased by $82,000 in 1995 due to the release of new options in 1995 for
the Company's character generator product lines.
 
    MANAGEMENT FEE.  In December 1991, the Company entered into a management
agreement (the "Management Agreement") with an affiliate of Sepa to provide
business and technical services to the Company. This agreement was subsequently
transferred to Sepa. In December 1995, the Company (under its new management)
agreed to terminate the Management Agreement upon payment to Sepa of $2 million.
This is anticipated to result in aggregate savings to the Company of $1.0
million for the two year period ending December 31, 1997.
 
    INTEREST EXPENSE, NET.  Interest expense, net increased 2.1% to $536,000 in
1995 from $525,000 in 1994. This increase was primarily due to an increase in
the average prime rate of interest in 1995 and additional interest expense
related to the Company's capital lease obligations entered into in December
1994. This increase was offset by earnings on the Company's cash equivalents.
 
    INCOME BEFORE PROVISION FOR INCOME TAXES.  Income before provision for
income taxes was $7.9 million for 1995, an increase of $16.9 million over the $9
million loss in the prior year. Net income for the current year included a $2
million charge related to the termination of the Company's Management Agreement
with Sepa, which is further described in Note 17 to the Consolidated Financial
Statements, and a recapture of the prior year's restructuring charge of $1.3
million. For details of changes in the West Coast
 
                                       21
<PAGE>
restructuring charge in 1995, see Note 18 to Consolidated Financial Statements.
Exclusive of the management fee charge in 1995 and amounts related to the West
Coast restructuring charge in 1994 and 1995, the income before provision for
income taxes increased $5 million due primarily to increases in net sales and
gross margins for 1995 coupled with increased efficiencies and cost savings
measures as well as the benefit of the West Coast restructuring commencing in
the third quarter of 1994.
 
    INCOME TAXES/EQUIVALENT PROVISION.  A total income tax/equivalent provision
of $470,000, or 6%, was recorded in 1995 and included a tax benefit of
approximately $1.0 million which was recognized as a result of the reduction in
the valuation allowance provided on deferred tax assets. The valuation allowance
was reduced because management believes that the Company will generate
sufficient future taxable income from ordinary and recurring operations to
realize the deferred tax assets. At December 31, 1995, the Company had recorded
a valuation allowance of approximately $5.4 million.
 
YEAR ENDED DECEMBER 31, 1994 COMPARED TO THE YEAR ENDED DECEMBER 31, 1993
 
    NET SALES.  Net sales increased 14.4% to $42.8 million in 1994 from $37.4
million in 1993. This increase was attributable to significant increases in
sales across the range of the Company's graphics products. Net sales of the
Company's three flagship high-end products increased 27%, with the iNFiNiT!
workstation showing a 29% volume growth, the entry level MAXINE! a 50% volume
growth and the intermediate MAX!> a 9% unit price improvement due to the
increased sale of featured options. The Codi titling and logo generators had a
28% unit volume growth, with an average system price improvement over the prior
year of 93%. In 1994, net sales also included a software license fee of $610,000
for use of the source code of the Company's Liberty paint and animation
software.
 
    GROSS PROFIT.  Gross profit increased 15.9% to $23.9 million in 1994 from
$20.6 million in 1993 primarily as a result of a 14.4% increase in net sales.
Gross margin as a percentage of net sales increased to 55.8% in 1994 from 55.1%
in 1993 as a result of management's efforts to enhance productivity in the
factory and the benefits of the West Coast restructuring.
 
    SELLING, GENERAL AND ADMINISTRATIVE EXPENSES.  Selling, general and
administrative expenses increased 6.3% to $14.3 million in 1994 from $13.5
million in 1993, but decreased as a percentage of net sales to 33.4% in 1994
from 35.9% in 1993. This decrease was primarily due to savings from the
consolidation of the Company's two Melville facilities, reduction in staffing
levels and the West Coast restructuring, which in turn were offset by an
increase in costs related to the 14.4% increase in net sales, new marketing and
advertising initiatives, moving expenses and the write-off of the leasehold
improvements related to the consolidation of the Company's two Melville
facilities.
 
    RESEARCH AND DEVELOPMENT EXPENSES.  Research and development expenses,
including the amortization of capitalized software development costs, increased
16.5% to $4.2 million in 1994 from $3.6 million in 1993 due to strategic
initiatives in improving the Company's profitable product lines. Amortization of
software development costs (included in research and development expenses)
increased $167,000 as a result of the release of new products and options since
1993.
 
    WEST COAST RESTRUCTURING.  As of September 30, 1994, the Company's West
Coast operations, CMX and Aurora, reflected a continuing trend of poor operating
performance. Due to these disappointing results, the lack of certain products in
the high growth sector of the market and the strategic decision by management to
redirect its product lines to a broader base market and to reengineer its
research and development focus, the Company initiated a plan to restructure the
West Coast operations.
 
    Consequently, the Company decided to eliminate unprofitable product lines
such as CMX 6000, Cinema, Gemini, LSI and the 3500 and 3600 series product
lines, reduce the West Coast workforce by 30% (or 12 employees), write-down to
estimated net realizable value certain assets directly attributable to the
unprofitable product lines, write-off software costs that the Company believed
no longer fit its strategic
 
                                       22
<PAGE>
initiative and focus, dispose of certain assets, accrue losses for the
restructuring period of October 1, 1994 through March 31, 1995 and downsize the
Company's Santa Clara, California facility.
 
    The result of these measures was a restructuring charge of $12.7 million for
the West Coast operations. The specific components of the restructuring charge
broken-out between asset write downs and cash outlays were as follows (in
thousands):
 
<TABLE>

Asset write downs:

  Other............................................................        273
                                                                     ---------
      Total........................................................  $  12,716
                                                                     ---------
                                                                     ---------
</TABLE>
 
    The cash outlays required by the restructuring have been funded by the
Company's profitable product lines. Cash outlays estimated for the six month
restructuring period were $3.8 million, of which $1 million was made by December
31, 1994. The loss on the lease was to be funded over the remaining lease term
of 31 months subsequent to the restructuring period. In 1995, a sublease was
obtained. The Company's graphics division had been funding the operating losses
of CMX and Aurora out of its working capital since CMX and Aurora began their
trend of unprofitability.
 
    Operating results as a result of the West Coast restructuring were projected
to benefit by a savings of over $2 million for 1995, principally due to a
reduction in annual salaries and employee benefits of $750,000, a decrease in
depreciation and amortization expense of $200,000 per year, a reduction of
overhead costs of approximately $200,000 per year and a reduction in losses on
unprofitable product lines of approximately $850,000 per year. The Company
believes such savings have been substantially realized.
 
    INTEREST EXPENSE, NET.  Interest expense, net decreased 26.4 % to $525,000
in 1994 from $714,000 in 1993. This decrease was primarily due to the reduction
in the Company's secured credit facility from $6.5 million to $4.5 million at
December 31, 1994, offset in part by the increase in the average prime rate over
the prior period.
 
    INCOME TAXES/EQUIVALENT PROVISION.  Due to the West Coast restructuring
charge of $12.7 million, which included the disposition of inventory related to
unprofitable product lines, the Company had a book and tax loss for 1994 and,
accordingly, there was no provision or benefit for income taxes.
 
    The operating loss of $8.5 million would have been an operating profit of
$4.2 million exclusive of the West Coast restructuring charge of $12.7 million
compared to $2.7 million for 1993. This increase was mainly attributable to the
fact that the fourth quarter losses of the West Coast operations of
approximately $1.0 million were provided for in the $12.7 million West Coast
restructuring charge taken in the quarter ended September 30, 1994 and also due
to the increase in sales and gross margins in 1994.
 
QUARTERLY RESULTS OF OPERATIONS
 
    The following tables set forth certain unaudited quarterly statement of
operations data for each of the Company's last seven quarters, and such data
expressed as a percentage of net sales for each quarter. This data has been
prepared on a basis consistent with the Company's audited consolidated financial
statements included elsewhere in this Prospectus and includes all necessary
adjustments, consisting only of normal recurring accruals, that the Company
considers necessary for a fair presentation. The operating results for
 
                                       23
<PAGE>
any quarter are not necessarily indicative of results for any future period. In
view of recent developments, including the acquisition of Pro-Bel and the
Company's recent growth, the Company believes that quarter-to-quarter
comparisons of its financial results are not necessarily meaningful and should
not be relied upon as an indication of future performance.

    The Company's quarterly operating results depend, among other things, on the
volume and timing of product orders received and delivered during the quarter
and the timing of new product introductions by the Company.
 
    The quarter ended March 31, 1996 showed lower net sales compared to the
quarter ended December 31, 1995. The fourth quarter historically has been
Chyron's strongest quarter. The quarter ended June 30, 1996 increased 64% over
the quarter ended March 31, 1996 primarily as a result of the acquisition of
Pro-Bel during the quarter as well as seasonal purchases of equipment made in
anticipation of media coverage of the Olympics and the political primaries,
conventions and elections in the summer and fall of 1996. The quarter ended June
30, 1996 was the first quarter in which the Company reported consolidated
results with Pro-Bel. The quarter ended September 30, 1996 decreased from the
quarter ended June 30, 1996 but increased over the comparable 1995 quarter by
46%, primarily as a result of the acquisition of Pro-Bel.
 
LIQUIDITY AND CAPITAL RESOURCES
 
    On February 1, 1996, Pro-Bel, entered into several agreements with a bank to
obtain borrowing facilities totaling 1.5 million pounds sterling (approximately
$2.4 million at the September 30, 1996 exchange rate). One of the facilities is
secured by Pro-Bel's outstanding accounts receivable. These facilities replaced
former bank facilities which had expired, and are used for working capital.
 
    On March 28, 1996 and April 16, 1996, the Company entered into agreements
with a bank to obtain a revolving credit facility of $10 million and a term loan
of $8 million, respectively. The revolving portion of the facility matures 3
years from closing, while the term portion matures 4 years from closing. The
entire facility is secured by the Company's properties and assets. This facility
replaced the $10 million secured credit facility which was due to expire on
April 27, 1997. In April 1996, a portion of this new credit facility was used to
fund the acquisition of Pro-Bel.
 
    On April 12, 1996, the Company issued, as part of the purchase price,
promissory notes to the shareholders of Pro-Bel for 3.5 million pounds sterling
($5.3 million). The promissory notes are secured by an irrevocable letter of
credit from a bank and limit amounts available under the revolving credit
facility described above. The notes are due on or before April 15, 1998.
 
    At September 30, 1996, the Company had operating lease commitments for
equipment and factory and office space totaling $12.4 million, of which $1.3
million is payable within one year.
 
    To finance the acquisition of Pro-Bel, the Company incurred additional debt
of $7.2 million and used cash on hand of $6.9 million. Since the acquisition of
Pro-Bel, the Company's consolidated financial statements include the Pro-Bel
accounts, as adjusted for purchase accounting. At the date of acquisition,
inventory increased by $7.8 million, accounts receivable increased by $5.9
million and accounts payable increased by $9.2 million which, in sum with other
current assets acquired and current liabilities assumed, increased working
capital by $3.5 million. Additionally, at the date of acquisition, property and
equipment increased by $8.8 million, excess of cost over net assets acquired of
$7.5 million was recorded and $3.6 million of Pro-Bel debt was assumed.

    THE FOLLOWING BUSINESS SECTION CONTAINS FORWARD-LOOKING STATEMENTS WHICH
INVOLVE RISKS AND UNCERTAINTIES. THE COMPANY'S ACTUAL RESULTS COULD DIFFER
MATERIALLY FROM THOSE ANTICIPATED IN THESE FORWARD-LOOKING STATEMENTS AS A
RESULT OF CERTAIN FACTORS, INCLUDING THOSE SET FORTH UNDER "RISK FACTORS" AND
ELSEWHERE IN THIS PROSPECTUS.
 
    The Company develops, manufactures, markets and supports a broad range of
equipment, software and systems that facilitate the production and enhance the
presentation of live and pre-recorded video, audio and other data. The Company's
products enable users to (i) create and manipulate text, logos and other graphic
images using special effects such as 3D transforming, compositing and painting;
(ii) manage, monitor and distribute video, audio and other data signals; and
(iii) control edit processes and automate broadcast equipment. The worldwide
market for equipment, software and systems used in the production and
presentation of video and audio content encompasses major television networks,
cable television broadcasters, direct to home satellite program distributors,
production companies and post-production houses, as well as organizations and
individuals creating materials such as corporate and specialized video and audio
presentations. The Company believes that the proliferation of users of high
quality video and audio content is increasing the demand for products used in
the production and presentation of such content. The Company's high performance
graphics systems are used daily by many of the world's leading broadcast
stations to display news flashes, election results, sports scores, stock market
quotations, programming notes and weather information. The Company's signal
management systems interconnect video, audio and data signals to and from
equipment within a studio's control room or edit suite, as well as to and from
signal transmission sites. The Company's control and automation systems are used
to automate the steps used in the management, editing and distribution of video
and audio content.
 
INDUSTRY BACKGROUND
 
    OVERVIEW.  The creation and delivery of video and audio content has three
distinct stages: production, post-production and distribution. Production
involves shooting video or film, recording sound and creating computer-generated
graphics and other elements for special visual effects. Both still and animated
images are created and stored at this point. During post-production, video and
audio signals are processed and edited using sophisticated equipment to combine
disparate elements, such as titles, graphics, still and moving images, and
computer-generated special effects through techniques such as scene sequencing,
compositing, layering and touch-up. Important attributes of the equipment used
in these processes include real time performance, high signal quality, high
reliability and feature and function upgradeability. The post-production process
may be eliminated when content is broadcast live or live to tape. Distribution
is the delivery of the finished content. The outlets available for distribution
of video and audio content are proliferating as new cable, satellite and direct
view alternatives supplement traditional broadcast delivery systems. Additional
outlets include video tapes, video discs, CD-ROMs and film.
 
    Recently, a fundamental technological change has been occurring as
production, post-production and distribution facilities, which have historically
used an analog signal format, have been gradually converting, when appropriate,
to a digital signal format. Digital technology allows the reduction of internal
signal wiring, amplifier and other ancillary devices, increased signal quality
and superior reproduction capabilities. Prior to installing digital production
and post-production devices, all or part of the routing switcher, the device
which interconnects the signals of the various devices, must be converted to
digital. Converting to digital also partially prepares a facility for the
introduction of new digital standards, including ATV and HDTV which require a
digital signal.
 
    In addition, as "open system" hardware and software become more powerful and
reliable, they are being adapted for use in the real time creation,
manipulation, storage and delivery of video and audio content. The use of
hardware, including computers, solid state memory devices, disk drives and
electronic writing tablets, may speed product development, defer price increases
and reduce repair costs and repair time. The use of software developed for mass
markets may permit greater interoperability between
 
                                       26
<PAGE>
devices, easier modification and allow the customer or other third-party
software developers to add or enhance the devices' internal software for
additional functionality.
 
    An important consideration for customers evaluating the incorporation of new
technologies, such as digital signal formats and open systems, into new or
existing facilities is the ability to preserve their investments in equipment
and systems. These investments, which include significant capital expenditures
and design, installation and training costs, result in a customer requirement
for modular, upgradeable products with a long anticipated useful life.
 
    PRODUCTION AND POST-PRODUCTION.  In the production and post-production
processes, video and audio content elements are created, manipulated, enhanced
and edited in the studio's control room or edit suite. An edit control system
manages the equipment in the studio's control room or edit suite, accessing
video and audio elements as required and sequencing them to editorial tastes.
The equipment used in these processes, which may be digital or analog, includes
video production switchers, video special effects devices, audio processing
units, paint and animation systems, still storage devices, character generators
and graphic systems. The sources of the numerous content elements as well as the
storage devices for finished edited content, such as video tape machines or disk
based storage systems, can each be analog or digital. These various devices are
typically interconnected through routing switchers which provide quick and easy
access to video, audio and other data from various devices. Routing switchers
are available to handle analog and digital signal formats and peripheral
products are available to convert signals between the two.
 
 The following is a diagram of various steps in the broadcast process with the
                        equipment of the Company noted.
 
                                [INSERT DIAGRAM]
 
    Post-production facilities may be categorized as high-end, mid-range and
low-end. High-end facilities typically create programming for national
television and cable networks and advertising agencies that create national
commercials. Mid-range facilities typically create programming for local
broadcasters, regional advertising agencies and producers of corporate
presentations. Low-end facilities typically create local cable commercials, low
budget programs and specialized videos. Finished or edited content, whether
created at independent post-production facilities or in-house facilities that
are located within a broadcast, movie or television studio, cable network,
corporation or other organization, reaches its audience through various
distribution methods.
 
    DISTRIBUTION.  Distribution is the final step by which content is delivered
to the consumer. Over the air terrestrial broadcasting has been and continues to
be the most common form of content mass distribution in the United States and
most other parts of the world. In the United States, the broadcast structure
initially included the ABC, CBS, NBC and PBS networks and their approximately
two hundred local broadcast station affiliates per network. In the last few
years, however, new networks have been established, including FOX, UPN and WB.
Outside the United States, many traditional broadcasters have historically been
government owned and often non-commercial. In recent years, many governments
have
 
                                       27
<PAGE>
privatized their broadcast operations. Privatization has typically created the
need for commercial production, promotional spots and attractive program content
with sophisticated production values. Such content can be produced at the
broadcast station or newly established independent post-production facilities.
In many cases, the privatization of state broadcast operations has also made
television channels available to new private broadcasters. These broadcasters
have often commissioned and built complete new production, post-production and
distribution facilities to meet their own requirements.
 
    For many years, cable penetration into United States households was limited
and cable systems offered only 20 to 30 channels. According to industry sources,
however, today's cable penetration exceeds 60% of all households in the United
States and cable delivery technology is capable of delivering over 100 channels.
As a result, cable networks, including Time Warner (CNN, CNN Headline News, HBO,
Showtime), Disney/ABC (ESPN, Disney Channel), General Electric/NBC (CNBC,
MSNBC), Viacom (MTV, Nickelodeon), News Corporation/Fox (FX, Fox News Channel,
Sky Channel) and others, are expanding by establishing new program channels.
This proliferation of cable program channels requires additional production,
post-production and distribution resources. The potential adoption of digital
transmission to a home set-top box may further increase the demand for such
resources. Outside the United States, in areas where low channel capacity cable
systems have been operating, cable expansion has generally been similar to that
in the United States. In many areas with limited cable systems infrastructure,
however, direct to home satellite program distribution ("DTH") is being
established instead of cable systems. DTH is now operating in the United States
and internationally. In the United States, many of the program services
available on conventional cable TV systems are also available on DTH. DTH
operators in the United States include Direct TV, USSB, Primestar, Echostar and
Alphastar. Internationally, they include Direct TV Latin America, BSkyB and
OPTUS.
 
    Both in the United States and internationally, the proliferation of new
distribution channels require additional production, post-production and
distribution facility resources. In addition, international program networks
such as CNN, NBC, MTV, ESPN and others provide specialized programming for
services such as CNN International, NBC Super Channel, MTV Latin America and
ESPN Asia. As a result, these networks may seek equipment suppliers that can
sell and provide service, support and train in locations throughout the world
where they are establishing infrastructure.
 
    Video and audio content is also produced for and distributed through a
variety of other formats, such as video tapes, CD-ROMs and film. Advances in
technology have begun to allow Local Area Networks and the Internet to be used
as distribution channels for video and audio content. Accordingly, demand for
content for these formats may also require additional production,
post-production and distribution resources.

      its established reputation to sell additional products to existing
      customers in its current markets. For example, the Company plans to
      increasingly market its Pro-Bel signal management systems to its Chyron
      graphics systems customers.
 
    - ADDRESS LOW-END AND EMERGING MARKETS. The Company plans to leverage its
      established reputation and core technologies as it addresses low-end
      production, post-production and distribution markets with current and
      future product offerings. In addition, the Company plans to address new
      digital video applications as they emerge.
 
    - EXPAND GLOBAL PRESENCE. The Company plans to expand its international
      operations to support the needs of both new customers as well as the
      Company's existing customers as they expand into markets outside their
      traditional geographical operating areas. The Company plans to expand its
      international marketing and sales staff as well as appoint additional
      distributors. For example, the Company recently opened a sales and support
      office in Hong Kong. Currently, approximately 70% of the Company's annual
      sales are made to customers in the United States and the United
 
                                       29

      Kingdom. The Company believes there exists a significant opportunity to
      increase its sales in other geographic areas.
 
    - PURSUE STRATEGIC ACQUISITIONS AND ALLIANCES. The Company plans to continue
      to pursue strategic acquisitions and alliances to increase its product
      offerings and expand its global reach. In April 1996, the Company acquired
      Pro-Bel, a United Kingdom based developer, manufacturer and marketer of
      routing switchers and other signal management products, and purchased a
      minority interest in RT-SET, an Israeli developer of virtual reality
      television studio systems. See "Risk Factors--Risks Associated with the
      Company's Acquisition and Alliance Strategy," "The Company" and
      "Business--RT-SET Relationship."
 
    - UTILIZE OPEN PLATFORMS. The Company intends to continue to utilize, where
      appropriate, general purpose devices and software written to industry
      standard operating systems. Where the use of general purpose hardware is
      not appropriate, the Company plans to continue to develop proprietary
      hardware for products to deliver real time performance at the highest
      signal quality industry standard.

MARKETING AND SALES
 
    The Company markets its products and systems to traditional broadcast and
post-production facilities, government agencies, educational institutions and
telecommunications and corporate customers.
 
    In order to maintain and increase awareness of its products, the Company
displays at the major domestic and international trade shows of the broadcast
and computer graphics industries. In the United States, the Company exhibits at
the National Association of Broadcasters (NAB) and ACM SIGGRAPH conventions. It
also exhibits at the International Broadcasters Conventions (IBC) in Europe,
INTERBEE in Japan and Broadcast-Asia in China. The Company uses direct-mail
campaigns and places advertisements in broadcast, post-production and computer
industry publications.
 
    Sales of the Company's products in the United States and the United Kingdom
are made through Company direct sales personnel, dealers, independent
representatives, systems integrators and OEMs. Direct sales, marketing and
product specialists serving the domestic markets act as a link between the
customer and the Company's development teams. An early understanding of the
requirements of end users allows the Company to quickly respond to its
customers' changing needs.
 
    Export sales of the Company's products are made through dealers and several
representatives covering specific territories. Some of the dealers have been
granted exclusive rights to sell certain products in specified territories. The
Company recently opened a sales and support office in Hong Kong in order to
better service the growing markets of Asia. In some territories, dealers sell
products from all of Company's product categories; in other territories, dealers
handle only a subset of products.
 
SERVICE, SUPPORT AND TRAINING
 
    The Company offers comprehensive technical service, support and training to
its customers through 24 hour per day, 7 day a week access to trained service
and support professionals.
 
    Training courses are available through the Company which range in length
from a few days to a few weeks and consist of a mix of classroom discussions and
hands-on training. The Company offers training courses for many of its products
at its Melville (New York) headquarters and its Reading (United Kingdom),
Atlanta (Georgia) and Burbank (California) centers. The Company also conducts
on-site training. Installation assistance, hardware and software, maintenance
contracts and spare parts are made available to the Company's customers. Support
contracts and a responsive spare parts supply service facilitate customer
satisfaction. Service is provided both domestically and internationally by the
Company or its appointed dealers and representatives. The Company also provides
sales and service support to its dealers from time to time. The Company provides
warranties on all of its products ranging from 90 days to five years.
 
COMPETITION
 
    The market for graphics imaging, editing and animation systems, signal
routing systems and media storage systems is highly competitive and is
characterized by rapid technological change and evolving industry standards.
Rapid obsolescence of products, frequent development of new products and
significant price erosion are all features of the industry in which the Company
operates. The Company anticipates increased competition from both existing
companies and new market entrants. The Company is currently aware of several
major and a number of smaller competitors. In the graphics area, the Company
believes its primary competitors are Aston Electronic Designs Limited, Digital
Graphix Inc., Dynatech Corporation, Quantel Inc. and Scitex Corporation Ltd. In
the signal management area, the Company believes its primary competitors are
Dynatech Corporation, Leitch Incorporated, Philips Electronics N.V., Sony
Corporation and Tektronix Inc. In the control and automation area, the Company
believes its primary competitors are Accom, Inc., Louth Automation, Philips
Electronics N.V., Sony Corporation and Tektronix, Inc. Many of these companies
have significantly greater financial, technical, manufacturing and
 
                                       35
<PAGE>
marketing resources than the Company. In addition, certain product categories
and market segments, on a region-by-region basis, in which the Company does or
may compete, are dominated by certain vendors. As a result, the Company's
ability to compete in these areas may be limited.
 
    The Company believes that its ability to compete depends on factors both
within and outside its control, including the success and timing of new product
developments introduced by the Company and its competitors, product performance
and price, market presence and customer support. There can be no assurance that
the Company will be able to compete successfully with respect to these factors.
Maintaining any advantage that the Company may have over its competitors will
require continuing investments by the Company in research and development, sales
and marketing and customer service and support. In addition, as the Company
enters new markets, whether through acquisitions, alliances with other companies
or on its own, the Company may encounter distribution channels, technical
requirements and competitive factors that differ from those in the markets in
which it currently operates. There can be no assurance the Company will be able
to compete successfully in these new markets. In addition, increased competition
in any of the Company's current markets could result in price reductions,
reduced margins or loss of market share, any of which could materially and
adversely affect the Company's business, financial condition and results of
operations. There can be no assurance that the Company will be able to compete
successfully against current or future competitors.
 
RESEARCH AND DEVELOPMENT
 
    The Company's research and product development, conducted in Melville, New
York, Reading, United Kingdom, and Santa Clara, California is focused on the
continued enhancement of its existing products and the development of new ones.
 
    The Company has historically oriented its efforts toward the development of
complete systems, rather than of either hardware or software standing alone. A
strategic engineering group evaluates hardware and software technologies.
 
    During 1993, 1994 and 1995, the Company expensed approximately $3.6 million,
$4.2 million and $4.1 million, respectively, for research and development and
amortization of capitalized software development costs incurred in connection
with the development of new graphics products and the modification and
enhancement of existing products.
 
MANUFACTURING
 
    The Company has final assembly and system integration operations located in
Melville and Reading. The Company primarily uses third-party vendors to
manufacture and supply all of the hardware components and sub-assemblies
utilized in the Company's graphics systems and relies upon a combination of
third-party vendors and internal manufacturing for components and sub-assemblies
utilized in the Company's signal management systems. The Company designs many of
its system components to its own specifications, including metal and electronic
parts and components, circuit boards and certain subassemblies. It assembles
such items and standard parts, together with internally-developed software, to
create final products. The Company then performs testing and quality inspections
of each product.
 
PATENTS AND PROPRIETARY RIGHTS
 
    The Company's success depends upon its ability to protect its proprietary
software technology and operate without infringing the rights of others. It
relies on a combination of patent, trademark and trade secret laws to establish
and protect its proprietary rights in its technology.
 
    The Company currently has seven patents. The names Chyron, Scribe, Chyron
Scribe, Chyron Scribe Junior, Chyron SuperScribe, iNFiNiT!, MAX!>, MAXINE!,
CODI, I(2), Intelligent Interface, Intelligent
 
                                       36
<PAGE>
Interface (I(2)), CMX, CMX AEGIS, CMX OMNI, Aurora, Liberty, PROCION and PROCION
INNOVATIVE CONTROL SOLUTIONS are registered trademarks of the Company. The
Company also has rights in trademarks and service marks which are not federally
registered, including the Chyron Care service mark. The Company does not have
registered copyrights on any of its intellectual property.
 
    The duration of patents in the United States is 20 years from priority or 17
years from issuance. As a result, the Company's existing patents will begin to
expire commencing in the year 1998. There can be no assurance that any of the
Company's patents will not be invalidated or the Company will obtain new patents
for its pending applications. In addition, there can be no assurance any claims
allowed from existing or pending patents will be of sufficient scope or strength
or be issued in the primary countries where the Company's products can be sold
to provide meaningful protection or any commercial advantage to the Company. The
laws of certain foreign countries in which the Company's systems are sold may
not protect the Company's intellectual property rights to the same degree as the
United States, making the possibility of piracy of the Company's systems and the
underlying technology more likely.
 
    To date, the Company has not undertaken an infringement analysis to identify
whether competitive product offerings infringe on issued patents. Such analysis
is inherently complex, uncertain and subject to numerous factual and legal
judgments. Moreover, a determination whether the Company has established a
strong intellectual property position cannot be determined without making
additional assumptions as to the likely interpretation of existing patents and
the scope of future patents currently under review by the U.S. Patent and
Trademark Office. The Company believes that it is possible for competitors to
introduce viable competitive systems without infringing the Company's existing
patents and that the Company's product development efforts will be more
important to its competitive position than its patent position. Aside from
patent and trademark protection, the Company relies on various laws to protect
it from unfair competition and to protect its trade secrets and proprietary
rights.
 
    In the electronics industry, companies often receive notices alleging
infringement of patents or other intellectual property rights. While there is
currently no pending intellectual property litigation involving the Company, the
Company has been, and may from time to time continue to be, notified of claims
that it may be infringing patents, copyrights or other intellectual property
rights owned by third parties. There can be no assurance that these or other
companies will not, in the future, pursue claims against the Company with
respect to the alleged infringement of patents, copyrights or other intellectual
property rights. In addition, litigation may be necessary to protect the
Company's intellectual property rights and trade secrets, to determine the
validity and scope of the proprietary rights of others or to defend against
third party claims of invalidity. Any litigation could result in substantial
costs and diversion of resources and could materially adversely affect the
Company's business, financial condition and results of operations.
 
    There can be no assurance that infringement, invalidity, right to use or
ownership claims by third parties or claims for indemnification resulting from
infringement claims will not be asserted in the future. If any claims or actions
are asserted against the Company, the Company may seek to obtain a license under
a third-party's intellectual property rights. There can be no assurance,
however, that if a license is available, it will be under terms acceptable to
the Company. The failure to obtain a license under a patent or intellectual
property right from a third party for technology used by the Company could cause
the Company to incur substantial liabilities and to suspend the manufacture of
the products utilizing the invention. In addition, if a license is not available
the Company may be required to redesign its products to eliminate infringement.
Such redesign, if possible, could result in substantial delays in marketing its
products and in significant costs. In addition, should the Company decide to
litigate such claims, such litigation could be extremely expensive and time
consuming and could materially and adversely affect the Company's business,
financial condition and results of operations, regardless of the outcome of the
litigation. See "Risk Factors--Dependence on Proprietary Technology; Risks of
Infringement."
 
    There can be no assurance that the steps taken by the Company regarding its
proprietary technology will be sufficient to deter misappropriation or that the
Company's competitors will not independently develop technologies that are
substantially equivalent or superior to the Company's technologies. In
 
                                       37
<PAGE>
addition, the laws of certain countries in which the Company's products are or
may be distributed do not protect the Company's products and intellectual rights
to the extent of the laws of the United States.
 
    The Company believes that, due to the rapid technological changes in the
electronics industry, the quality of its products, proprietary technology,
contract performance and the technical expertise and creative ability of its
personnel are more important in establishing and maintaining a technology
leadership position than the various legal protections afforded its technology.
 
EMPLOYEES
 
    As of November 30, 1996, the Company employed 405 persons on a full-time
basis, including 63 in sales and marketing, 159 in manufacturing and testing, 39
in customer support, service and training, 50 in finance and administration and
94 in research and development. None of these employees is represented by a
labor union. The Company has not experienced any work stoppages and considers
its relations with its employees to be good.
 
FACILITIES
 
    The executive offices and principal office of the Company and its graphics
business are located in Melville, New York pursuant to a lease that expires on
June 30, 2004. This facility consists of approximately 47,000 square feet and is
used for manufacturing, research and development, marketing and the executive
offices. The Company also leases approximately 15,000 square feet in Santa
Clara, California. This lease expires on October 31, 1997. In the United
Kingdom, the Company's principal office is located in Reading where it owns an
approximately 19,000 square foot facility. This facility is used for
manufacturing, research and development and marketing. The Company occupies
additional facilities in the United Kingdom in Reading and Andover which total
approximately 28,000 square feet pursuant to leases which expire from December
31, 1996 through September 24, 2020.
 
LITIGATION
 
    The Company is a party to PERCIVAL HUDGINS & COMPANY, INC. V. CHYRON
CORPORATION V. JOHN PERCIVAL, pending in the United States District Court, North
District of Georgia (Atlanta), Civil Action No. 1 95-CV-CAM. This is a breach of
contract action for an alleged success fee in connection with the sale of Common
Stock by Pesa and Sepa to the new investment group. Plaintiff seeks damages of
approximately $600,000. The Company has answered, denying all material
allegations, and has asserted a third party claim against plaintiff's principal,
alleging that he breached his fiduciary duties to the Company and is liable for
any amounts that might be awarded to plaintiff, together with counsel fees.
 
RT-SET RELATIONSHIP
 
    Through its recent alliance with RT-SET, the Company markets and supports
RT-SET's virtual studio systems in the United States. These systems integrate
live video and actors with virtual sets, composed of computer-generated 3D
graphics, to create a real-time composite image. RT-SET offers two systems:
LARUS, used for live-to-air programming, and OTUS, used for live-to-tape
programming. Either system may be used in conjunction with Chyron's iNFiNiT!
family of graphics systems and its Liberty paint and animation software. RT-SET
entered into an agreement with CBS News, pursuant to which the RT-SET virtual
studio was used by CBS News in its recent coverage of the Presidential elections
in the United States.
 
    Subsequent to the Company's investment in RT-SET, there were additional
equity investors in RT-SET. As a result, as of November 30, 1996, the Company's
interest was reduced from 19% to approximately 17% of the outstanding equity of
RT-SET. The Company maintains the option to acquire up to 51% of the equity of
RT-SET in exchange for Chyron Common Stock. In addition, the Company entered
into a marketing and cooperation agreement with RT-SET by which the Company
agreed to promote and sell RT-SET products and share expenses relating to such
activities. See "Risk Factors--Potential Dilution Related to RT-SET."

the holders of shares of common stock, including the loss of voting control to
others. The issuance of shares of preferred stock may delay, defer or prevent a
change in control without further action by the shareholders of the Company and
adversely affect the market price of the shares of Common Stock offered hereby.
The Company does not have any shares of preferred stock outstanding and has no
present intention to issue any shares of preferred stock.
 
REGISTRATION RIGHTS
 
    The holders of approximately 25,520,312 shares of Common Stock (the
"Registrable Shares") are entitled to certain rights with respect to the
registration of such shares under the Securities Act. Under the terms of
agreements between the Company and such holders, if the Company proposes to
register any of its securities under the Securities Act, either for its own
account or the account of security holders exercising incidental registration
rights, holders of 24,471,577 Registrable Shares are entitled to notice of such
registration and are entitled to include their Registrable Shares therein.
Holders of an additional 800,000 and 1,048,735 Registrable Shares will be
entitled to such incidental registration rights as of February 28, 1997 and
April 12, 1997, respectively.
 
    In addition, a sufficient number of holders of 24,471,577 Registrable Shares
have demand registration rights and can require the Company to file a
registration statement under the Securities Act with respect to their shares of
Common Stock, and the Company is required to use its best efforts to effect such
registration. The holders of such Registrable Shares may exercise such right,
beginning 90 days after the Effective Date, subject to the lock up, on four
occasions. In addition, as of July 12, 1997, a majority of the holders of
1,048,735 Registrable Shares will be able to exercise such right on not more
than one occasion.
 
                                       45
<PAGE>
    All such registration rights are subject to certain conditions and
limitations, including the right of the underwriters of an offering to limit the
number of such shares included in such registration. In addition, the Company
need not effect a requested registration within 90 days following any offering
of securities for the account of the Company. Generally, the Company is required
to bear the expense of all such registrations, except for stock transfer fees
and underwriters' fees, discounts or commissions relating to the sale of
securities by holders.
 
TRANSFER AGENT AND REGISTRAR
 
    The Company's Transfer Agent and Registrar is American Stock Transfer &
Trust Company, 40 Wall Street, New York, New York 10005.
 
                        SHARES ELIGIBLE FOR FUTURE SALE
 
    Future sales of substantial amounts of Common Stock in the public market
could adversely affect prevailing market prices and could impair the Company's
future ability to raise capital through the sale of its equity securities.
 
    Upon completion of this offering, based on the outstanding shares of Common
Stock at December 19, 1996 the Company will have 37,632,413 shares of Common
Stock outstanding, assuming no exercise of the Underwriters' Over-Allotment
Option and no exercise of the outstanding options to purchase 1,439,999 shares
of Common Stock. Of these shares of Common Stock, the 7,650,000 shares of Common
Stock offered hereby will be freely tradeable without restriction or further
registration under the Securities Act unless they are held by "affiliates" of
the Company as that term is used under the Securities Act and the regulations
promulgated thereunder. Of the remaining 32,382,413 shares of Common Stock held
by existing shareholders, 11,584,643 shares are "restricted shares" as defined
in Rule 144 (the "Restricted Shares"). Restricted Shares may be sold in the
public market only if registered or if they qualify for an exemption from
registration under Rules 144 or 144(k) promulgated under the Securities Act,
which rules are summarized below.
 
    Of the 11,584,643 Restricted Shares, up to 5,719,733 Restricted Shares will
become eligible for sale pursuant to Rule 144 during 1998; up to 3,000,000
Restricted Shares will become eligible for sale pursuant to Rule 144 during
1999; up to 2,000,000 Restricted Shares will become eligible for sale pursuant
to Rule 144 during 2000, and up to 804,910 Restricted Shares will become
eligible for sale pursuant to Rule 144 during 2001. An additional 1,433,333
shares currently subject to contractual limitations on sale or transfer will
become eligible for sale to the public on July 25, 1997. An additional
12,562,333 shares are subject to contractual limitations on sale or transfer as
described below, and will become eligible for sale beginning 180 days after the
Effective Date.
 
    On December 19, 1996, options to purchase 1,439,999 shares of Common Stock
(the "Options") were outstanding, of which 363,881 Options have or will become
exercisable during 1996, 480,550 Options will become exercisable during 1997,
453,896 Options will become exerciseable during 1999 and the remaining 141,670
Options will become exercisable during 1999. All but 451,666 of the Options will
expire in 2000. The remaining 451,666 Options will expire in 2001. The Company
has filed a registration statement under the Securities Act to register the
1,439,999 shares issuable upon exercise of the Options and an additional 226,667
shares reserved for issuance under the Company's 1995 Long-Term Incentive Plan,
thus permitting the resale of such shares when received by non-affiliates in the
public market without restriction under the Securities Act. See "Risk
Factors--Shares Eligible for Future Sale; Possible Adverse Effects on Future
Market Price."
 
    In general, under Rule 144 as currently in effect, beginning 90 days after
the date of this Prospectus, a person (or persons whose shares are aggregated),
including an affiliate, who has beneficially owned shares for at least two years
is entitled to sell within any three-month period a number of shares that does
not exceed the greater of 1% of the then outstanding shares of the Company's
Common Stock (approximately
 
                                       46
<PAGE>
      shares immediately after this offering) or the average weekly trading
volume of the Company's Common Stock on the NYSE during the four calendar weeks
preceding the date on which notice of the sale is filed with the Commission.
Sales under Rule 144 are also subject to certain requirements relating to the
manner of sale provisions, notice requirements and the availability of current
public information about the Company. Any person (or persons whose shares are
aggregated) who is not deemed to have been an affiliate of the Company at any
time during the three months preceding a sale, and who owns Restricted Shares
that were purchased from the Company (or an affiliate) at least three years
previously, would be entitled to sell such shares under Rule 144(k) without
regard to the volume limitations manner of sale provisions, public information
requirements or notice requirements. The Commission has recently proposed
reducing the initial Rule 144 holding period to one year and the Rule 144(k)
holding period to two years. There can be no assurance as to when or whether
such rule changes will be enacted. If enacted, such modifications may have a
material effect on the times when the shares of the Company's Common Stock
become eligible for resale.
 
    Beginning 180 days after the Effective Date of this offering, the holders of
12,562,333 Registrable Shares will be entitled to certain rights with respect to
the registration of such shares under the Securities Act. Holders of an
additional 1,848,735 shares of Common Stock will become entitled to certain
registration rights during 1997. See "Description of Capital Stock-Registration
Rights."

conditions, to purchase approximately the same percentage as the number of

exercise such option only to cover over-allotments made in connection with the
sale of shares of Common Stock offered pursuant to this Prospectus. The Selling

To the Board of Directors and
Shareholders of Chyron Corporation
 
    In our opinion, the accompanying consolidated balance sheet and the related
consolidated statements of operations, of shareholders' equity and of cash flows
present fairly, in all material respects, the financial position of Chyron
Corporation and its subsidiaries at December 31, 1995 and the results of their
operations and their cash flows for the year then ended in conformity with
generally accepted accounting principles. 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 audit. We conducted our audit
of these statements in accordance with generally accepted auditing standards
which 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, assessing the accounting principles
used and significant estimates made by management and evaluating the overall
financial statement presentation. We believe that our audit provides a
reasonable basis for the opinion expressed above.

                   NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
 
1. ORGANIZATION AND SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES
 
    Chyron Corporation's ("Chyron" or the "Company") business is organized under
a group concept that coordinates product development, marketing, advertising,
distribution and procurement. The Company has a multi-product approach for
filling customer requirements for equipment and systems used in video or film
production. These products include graphics, character generation systems,
electronic paint and animation systems and software. As a result, the Company
operates as one business segment.
 
BASIS OF PRESENTATION
 
    The consolidated financial statements include the accounts of the Company
and its wholly-owned subsidiaries. Until April 12, 1996, the Company's other
subsidiaries were inactive. On April 12, 1996, the Company acquired Pro-Bel
Limited and its subsidiaries (see Note 2). Certain prior year amounts have been
reclassified to conform to the current year presentation.
 
INTERIM RESULTS (UNAUDITED)
 
    The accompanying balance sheet at September 30, 1996 and the related
statements of income and of cash flows for the nine months ended September 30,
1995 and 1996 and the statement of shareholders' equity for the nine months
ended September 30, 1996 are unaudited. In the opinion of management, these
statements have been prepared on the same basis as the audited financial
statements and include all adjustments, consisting only of normal recurring
adjustments, necessary for the fair statement of results of the interim periods.
The data disclosed in these notes to the financial statements at such dates and
for such periods are also unaudited.
 
ACCOUNTING ESTIMATES
 
    The preparation of financial statements in conformity with generally
accepted accounting principles requires management to make estimates and
assumptions that affect the reported amounts of assets and liabilities and
disclosure of contingent assets and liabilities at the date of the financial
statements and the reported amounts of revenues and expenses during the periods
presented.
 
CASH AND CASH EQUIVALENTS
 
    Cash and cash equivalents include cash on deposit and amounts invested in a
highly liquid money market fund. Cash equivalents consist of short term
investments convertible into cash within 3 months or less. The carrying amounts
of cash and cash equivalents approximate their fair value.
 
INVENTORIES
 
    Inventories are stated at the lower of cost (first-in, first-out basis) or
market.
 
PROPERTY, EQUIPMENT AND DEPRECIATION
 
    Property and equipment are carried at cost and are depreciated on the
straight-line method over estimated useful lives of 3-10 years. Leasehold
improvements are amortized over the shorter of the remaining life of the lease
or the life of the improvement.
 
REVENUE RECOGNITION
 
    Revenue is recognized when finished products are shipped.

             NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (CONTINUED)
 
1. ORGANIZATION AND SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (CONTINUED)
INCOME TAXES
 
    In connection with the Company's emergence in 1991 from its reorganization
proceeding under Chapter 11 of the United States Bankruptcy Code, the Company
adopted "Fresh Start Reporting" in accordance with AICPA Statement of Position,
"Financial Reporting by Entities in Reorganization under the Bankruptcy Code."
 
    Fresh Start Reporting requires that the Company report an income tax
equivalent provision when there is book taxable income and a pre-reorganization
net operating loss carryforward. This requirement applies despite the fact that
the Company's pre-reorganization net operating loss carryforward would eliminate
(or reduce) the related income tax payable. The current and future year benefit
related to the carryforward is not reflected in Net Income, but instead is
recorded as a direct increase to Additional Paid-in Capital. The income tax
equivalent provision does not affect the Company's tax liability.
 
    The Company's deferred tax liability is determined based on the differences
between the financial reporting and tax bases of assets and liabilities and
enacted tax rates that are expected to be in effect for the years in which the
differences are expected to reverse. The deferred tax liability is reduced by
cumulative tax credits and losses carried forward for tax purposes and by tax
deductible temporary differences (deferred tax assets). See Note 13.
 
TRANSLATION OF FOREIGN CURRENCIES
 
    The functional currency for the Company's foreign operations is the
applicable local currency. The translation from the applicable foreign currency
to U.S. dollars is performed for asset and liability accounts using period-end
exchange rates and for revenue and expense accounts using a weighted average
exchange rate during the period. The gains or losses resulting from such
translation are recorded in the cumulative translation adjustment account which
is included in shareholders' equity.
 
COMMON STOCK EQUIVALENTS
 
    In December 1991, the Company issued to Pesa, Inc. ("Pesa"), a Delaware
corporation, $5 million of Convertible Subordinated Notes ("Notes"). The Notes
were convertible into shares of common stock at a conversion price of $.20 per
share. As of December 31, 1995, all of the Notes had been converted into shares.
See Note 11.
 
    In January 1992, shareholders of the Company, other than Pesa, received one
warrant for every two shares of common stock held when the Company issued
5,795,555 Common Stock Purchase Warrants. Each warrant entitled its holder to
purchase one share of common stock at $.20 per share. These warrants expired on
January 31, 1996. As of December 31, 1995, a total of 4,070,024 Common Stock
Purchase Warrants had been exercised. In January 1996, an additional 1,138,523
warrants were exercised.
 
    During 1995, the Company's Board of Directors granted 3,125,000 Incentive
Stock Options to certain employees for the purchase of Chyron common stock at a
purchase price ranging from $1.625 to $1.875. Additionally during 1995, 90,000
Non-Incentive Stock Options were granted to members of the Board of Directors at
a purchase price of $1.875. The exercise price of the stock options granted
represents the quoted closing market price at the dates of the grant. The
options vest over three years and expire on July 25, 2000. During 1995, no
options were exercisable. See Note 12.

             NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (CONTINUED)
 
1. ORGANIZATION AND SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (CONTINUED)
NET INCOME (LOSS) PER SHARE
 
    Net income (loss) per share is based on the weighted average number of
common shares outstanding during the period plus, when dilutive, additional
shares issuable upon the assumed exercise of outstanding Common Stock Purchase
Warrants and outstanding Incentive Stock Options. Fully diluted net income
(loss) per share is not presented since such presentation would not be
materially different from primary net income (loss) per share.
 
2. ACQUISITION OF PRO-BEL LIMITED
 
    On April 12, 1996, the Company acquired Pro-Bel Limited ("Pro-Bel"), located
in Reading, United Kingdom. Pro-Bel manufactures and distributes video signal
and switching equipment and systems. The consideration consisted of $6.9 million
in cash, $5.3 million in notes and 3,146,205 shares of restricted Chyron common
stock valued at $6.9 million.
 
    The acquisition of Pro-Bel was accounted for as a purchase. Accordingly, the
cost of the acquisition was allocated to the net assets acquired based upon
their estimated fair values. The excess of cost over the estimated fair value of
net assets acquired amounted to $7,532,000, which is being amortized over 12
years using the straight line method.
 
    The accompanying consolidated statement of operations includes the operating
results of Pro-Bel since the date of the acquisition. Pro forma unaudited
consolidated operating results of the Company and Pro-Bel for the nine months
ended September 30, 1995 and 1996, assuming the acquisition had been made as of
January 1, 1995 and 1996, respectively, are summarized below (in thousands
except per share amounts).

</TABLE>
 
    These pro forma results have been prepared for comparative purposes only and
include adjustments as a result of applying purchase accounting and conversion
to generally accepted accounting principles in the United States, such as
additional depreciation expense and cost of goods sold due to the step-up in
basis of fixed assets and inventory, respectively, goodwill amortization, a
decrease in research and development expense due to the capitalization of
software development costs and increased interest expense on acquisition debt
adjusted for tax effect. The pro forma financial information is not necessarily
indicative of the operating results that would have occurred if the acquisition
had taken place on the aforementioned dates, or of future results of operations
of the consolidated entities.
 
3. INVESTMENT IN RT-SET
 
    On February 29, 1996, the Company effectively purchased an option to acquire
a 19% interest in Real Time Synthesized Entertainment Technology, Ltd.
("RT-SET"), located in Tel Aviv, Israel. RT-SET develops, markets and sells real
time virtual studio set software and proprietary communications hardware that
operate on Silicon Graphics systems. In form, Chyron purchased shares of RT-SET
Convertible Preferred Stock in exchange for 2.4 million shares of Chyron
restricted common stock. In accordance with the purchase agreement, the 2.4
million shares of Chyron common stock were to be held in escrow and released in
tranches of one-third and two-thirds, subject to certain conditions. During
1996, the first of these conditions was met, which resulted in the release of
800,000 shares of Chyron restricted common

stock to RT-SET. Upon the satisfaction of the remaining conditions, the
remaining 1,600,000 escrowed shares will be released. If the conditions are not
met, the shares of Chyron restricted common stock held in escrow will be
returned to the Company. Accordingly, the transaction has been recorded as the
purchase of a right to acquire a 19% interest in RT-SET. RT-SET retains the
voting rights with respect to the escrowed Chyron shares while such shares are
held by the escrow agent. The acquisition was recorded at the estimated fair
value of the Chyron restricted common stock released from escrow. In addition,
Chyron was granted certain call option rights which, if and when exercised, will
result in the Company owning up to a 51% interest in RT-SET.

    (a) On March 28, 1996 and April 16, 1996, the Company entered into
agreements with a bank to obtain a revolving credit facility of $10 million and
a term loan of $8 million, respectively. The entire facility is secured by the
Company's assets. Borrowings are limited to amounts computed under a formula for
eligible accounts receivable and inventory. Additionally, an over-advance is
available above the borrowing formula in an amount not to exceed $3 million.
Interest on the revolving credit facility is equal to adjusted LIBOR plus 175
basis points or prime (8.25% at September 30, 1996) and is payable monthly. The
term loan is payable in quarterly installments of $500,000, commencing June 1,
1996. Interest on the term loan is equal to adjusted LIBOR plus 200 basis points
or prime (8.25% at September 30, 1996) and is payable monthly.
 
    (b) At December 31, 1995, the Company had $4.7 million outstanding with a
financial institution under a secured revolving credit facility. Interest was
payable monthly at the prime rate (8.5% at December 31, 1995) plus 2% per annum.
The facility was due to expire on April 27, 1997, but was replaced by the
banking facility described in (a) above in conjunction with the financing of the
acquisition of Pro-Bel.

10. LONG-TERM DEBT (CONTINUED)
    (c) Pro-Bel has a commercial mortgage term loan with a bank. The loan is
secured by a building and property located in the United Kingdom. Interest is
equal to LIBOR (5.98% at September 30, 1996) plus 2%. The loan (including
interest) is payable in quarterly installments of 80,600 pounds sterling
($127,000, converted at the September 30, 1996 exchange rate).
 
    (d) On April 12, 1996, the Company issued promissory notes to the
shareholders of Pro-Bel for $5.3 million (3.5 million pounds sterling) in
conjunction with the acquisition (See Note 2). The promissory notes are secured
by an irrevocable letter of credit from a bank. The amount of this irrevocable
letter of credit is included as an outstanding borrowing in the formula used to
calculate borrowing availability for the facilities described in (a) above.
Interest through April 15, 1997 is equal to LIBOR as of April 15, 1996 (6.46%)
and is payable quarterly. Interest from April 16, 1997 to April 15, 1998 is
equal to LIBOR as of April 15, 1997 and is payable quarterly. The notes are due
on or before April 15, 1998 and are subordinated to any obligations to a bank or
financial institution currently existing or subsequently entered into. The notes
can be prepaid without interest or penalty subsequent to November 1, 1996.
 
    (e) On February 1, 1996, Pro-Bel entered into an agreement with a bank to
obtain a trade finance facility of 750,000 pounds sterling ($1,182,000,
converted at the September 30, 1996 exchange rate). The facility is secured by
the Company's accounts receivable. Interest is equal to the bank's base rate
plus 2% (7 3/4% at September 30, 1996) on advances against accounts receivable
in pounds sterling and equal to the Barclays Bank PLC currency call loan rate
plus 2% (7 3/4% at September 30, 1996) on advances against foreign accounts
receivable. Interest is payable quarterly, in arrears.
 
    (f) On February 1, 1996, Pro-Bel entered into an agreement with a bank to
obtain an overdraft facility of 750,000 pounds sterling ($1,182,000, converted
at the September 30, 1996 exchange rate). Interest is equal to the bank's base
rate plus 2.5% (8 1/4% at September 30, 1996) and is payable quarterly
commencing in March 1996. The facility has a sublimit for overdraft on Pro-Bel's
wholly owned subsidiary, Trilogy Broadcast Limited, of 160,000 pounds sterling
($252,000, converted at the September 30, 1996 exchange rate). This facility is
payable upon written demand by the bank and any undrawn portion may be cancelled
by the bank at any time.
 
    (g) At December 31, 1994, the Company had $4.5 million outstanding with
another financial institution under a secured revolving credit facility, which
was classified as long-term debt as the Company, on February 1, 1995, had
received a commitment for the two-year facility described in (b) above. Interest
on the former facility was payable monthly at prime plus 2% per annum.
 
    Aggregate maturities of long-term debt in the next five years are as follows

of Incentive Stock Options. In May 1996, the shareholders approved an amendment
to the Plan to provide that all Directors who are not officers of the Company
shall receive, on an annual basis on the last trading date of each July, stock
options for 10,000 shares of the Company's common stock, at an exercise price
equal to the quoted closing market price of the stock on the date of grant.

Additionally, on July 31, 1995, the non-employee members of the Board of
Directors received Non-Incentive Stock Options for the purchase of 90,000 such
shares at $1.875 per option share, the quoted closing market price at the date
of grant. The options to employees vest over three years at 33 1/3% per annum
and expire on July 25, 2000. During 1995, no options were exerciseable.

    The Company has deferred tax assets and deferred tax liabilities as
presented in the table below. The net deferred tax assets are subject to a
valuation allowance, which was $14.5 million and $5.4 million at December 31,
1994 and 1995, respectively. This valuation allowance is primarily attributable
to a pre-Chapter 11 reorganization net operating loss carryforward and
pre-Chapter 11 reorganization deductible temporary differences. As a result of
current and projected future profitability, the allowance was partially reduced
in 1995.

paid to retirees are based upon age at retirement, years of credited service and
average compensation. Pension expense is actuarially determined using the
projected unit credit method. The Company's policy is to fund the minimum
contributions required under the Employees Retirement Income Security Act. The
assets held by the Pension Plan at December 31, 1995 include government
securities, corporate bonds and mutual funds.

14. BENEFIT PLANS (CONTINUED)
    In 1994, the Company adopted a 401(k) Plan exclusively for the benefit of
participants and their beneficiaries. All employees of the Company are eligible
to participate in the 401(k) Plan except non-resident aliens and employees who
are members of a union who bargain separately for retirement benefits during
negotiations. An employee may elect to contribute a percentage of his or her
current compensation to the 401(k) Plan, subject to a maximum of 20% of
compensation or the Internal Revenue Service annual contribution limit ($9,240
in 1994 and 1995), whichever is less. Total compensation that can be considered
for contribution purposes is limited to $150,000.
 
    The Company can elect to make a contribution to the Plan on behalf of those
participants who have made salary deferral contributions. During 1995, the
Company contributed $29,000 to the Plan. During 1994, no contributions were made
by the Company.
 
15. COMMITMENTS AND CONTINGENCIES

</TABLE>
 
    The operating leases contain provisions for maintenance and escalations for
real estate taxes. Total rent expense was $822,000, $530,000 and $496,000 for
1993, 1994 and 1995, respectively. The cumulative imputed interest in the
capital lease obligation was $40,000 at December 31, 1995.
 
    As of December 31, 1995, the Company had outstanding letters of credit
totalling $28,000 which guaranteed various trade activities. The contract amount
of the letters of credit approximates their fair value as the value for each is
fixed over the life of the commitment. The Company maintains a total credit line
of $100,000 specifically for obtaining standby letters of credit.
 
    There are several legal actions pending against the Company. It is
management's belief that none of these actions have merit nor will any outcome
materially affect the financial position of the Company.
 
16. NEW ACCOUNTING STANDARDS
 
    In March 1995, the Financial Accounting Standards Board ("FASB") issued
Statement of Financial Accounting Standards ("SFAS") No. 121, "Accounting for
the Impairment of Long Lived Assets and for Long Lived Assets to be Disposed
of." This accounting standard, which is effective for financial statements
issued for fiscal years beginning after December 15, 1995, is not expected to
have a material impact on the Company's results or financial reporting.

16. NEW ACCOUNTING STANDARDS (CONTINUED)
    In October 1995, the FASB issued SFAS No. 123, "Accounting for Stock Based
Compensation". This accounting standard is effective for financial statements
issued for fiscal years beginning after December 15, 1995. The Company plans to
adopt SFAS 123 in 1996 through disclosure in the Notes to the Consolidated
Financial Statements.
 
17. RELATED PARTY TRANSACTIONS
 
    Sepa, prior to the change in control discussed in Note 4, was the beneficial
owner of 73,414,732 shares of Chyron common stock. Consequent to such ownership,
Sepa had an amended and restated management agreement with Chyron whereby Chyron
agreed to pay management fees to Sepa at 2.5% of consolidated revenues through
December 31, 1997. The management fees under this agreement were subject to an
annual limitation of $1.5 million. In July 1994, Chyron took advantage of an
option to prepay the management fee at a 25% discount from the aggregate
estimated yearly fees for the period July 1, 1994 through December 31, 1995,
resulting in estimated aggregate total savings of $486,000 in fees for the
eighteen month period ending December 31, 1995.
 
    In December 1995, Chyron and Sepa agreed to terminate the Management
Agreement upon payment to Sepa of $2 million, which resulted in aggregate
savings for the Company of $1 million for the two year period ending December
31, 1997. The $2 million was paid in equal installments in December 1995 and
January 1996.
 
    The Company shared certain trade show and facility costs with Pesa and
Electronica. Such services amounted to $127,000, $303,000 and $30,000 for 1993,
1994 and 1995, respectively, and were billed to these related parties under a
usage based allocation. During 1993, the Company also performed certain
development work for Electronica and sold to it certain products that were
billed under an arm's length arrangement. These sales amounted to $272,000.
 
    As of December 31, 1994, the Company was indebted to Sepa and its affiliates
for $49,000, representing the cost of services provided and interest accrued on
the Convertible Subordinated Notes. Also, the Company had outstanding
receivables due from Electronica and its affiliates for equipment and services
at December 31, 1994 and 1995 amounting to $685,000 and $483,000, respectively.
In light of Electronica's filing "Suspension de Pagos" in Spain, reserves of
$545,000 and $389,000, respectively, have been provided for these receivables.
 
    A director of the Company is a partner of a law firm that rendered various
legal services to the Company for which the Company incurred costs of $273,000
during 1995.
 
18. WEST COAST RESTRUCTURING
 
    During the third quarter of 1994, as the result of continuing significant
operating losses by the Company's West Coast Operations and their inability to
meet revenue and operating targets, management implemented a restructuring plan
to eliminate a substantial number of the CMX and Aurora product lines and
consolidate certain remaining products into the Company's Graphics Operations,
with only certain product engineering capabilities remaining on the West Coast.
As a result, the Company recorded a $12.7 million charge to operations during
the third quarter of 1994, resulting from headcount reductions, consolidation
costs, write-downs of assets related to discontinued product lines and accrual
of estimated operating losses anticipated during the disposition period. For
1995, operating losses of $1,707,000 related to the discontinued product lines
were charged against the reserve for West Coast restructuring.

18. WEST COAST RESTRUCTURING (CONTINUED)
    During August 1995, the Company entered into an agreement to sublease a
portion of the office space for the West Coast Operations. The subleasing served
to decrease future rent commitments and, as a result, the Company reversed
$356,000 of the original $12.7 million charge to account for the decrease in
projected rent expense.
 
    Additionally, during 1995, the Company sold certain inventory that had been
fully reserved for in the original $12.7 million charge. The Company realized a
gain of $380,000 related to this inventory.
 
    During December 1995, the Company recaptured $603,000 of the original
restructuring charge as a result of lower than anticipated costs related to the
disposition period. As of December 31, 1995, the amount of the Reserve for West
Coast Restructuring of $158,000 represented future rent commitments through
1997.
 
    A summary of activity for 1995 related to the West Coast Restructuring is

ITEM 15. INDEMNIFICATION OF DIRECTORS AND OFFICERS.
 
    Pursuant to the statutes of the State of New York, a director or officer of
a corporation is entitled, under specified circumstances, to indemnification by
the corporation against reasonable expenses, including attorney's fees, incurred
by him in connection with the defense of a civil or criminal proceeding to which
he has been made, or threatened to be made, a party by reason of the fact that
he was such director or officer. In certain circumstances, indemnity is provided
against judgments, fines and amounts paid in settlement. In general,
indemnification is available where the director or officer acted in good faith,
for a purpose he reasonably believed to be in the best interests of the
corporation. Specific court approval is required in some cases. The foregoing
statement is subject to the detailed provisions of Sections 715, 717 and 721-725
of the New York Business Corporation Law ("BCL").
 
    The Registrant has entered into indemnity agreements with each of its
directors and executive officers. The indemnity agreements provide that
directors and executive officers (the "Indemnitees") will be indemnified and
held harmless to the fullest possible extent permitted by law including against
all expenses (including attorneys' fees), judgments, fines, penalties and
settlement amounts paid or incurred by them in any action, suit or proceeding on
account of their services as director, officer, employee, agent or fiduciary of
the Registrant or as directors, officers, employees or agents of any other
company or entity at the request of the Registrant. The Registrant will not,
however, be obligated pursuant to the agreements to indemnify or advance
expenses to an indemnified part with respect to any action (1) in which a
judgment adverse to the Indemnitee establishes (a) that the Indemnitee's acts
were committed in bad faith or were the result of active and deliberate
dishonesty and, in either case, were material, or (b) that the Indemnitee
personally gained in fact a financial profit or other advantage to which he or
she was not legally entitled, or (2) which the Indemnitee initiated, prior to a
change in control of the company, against the Registrant or any director or
officer of the Registrant unless the Registrant consented to the initiation of
such claim.
 
    The indemnity agreements require an Indemnitee to reimburse the Registrant
for expenses advanced only to the extent that it is ultimately determined that
the director or executive officer is not entitled, under Section 723(a) of the
BCL) and the indemnity agreement, to indemnification for such expenses.
 
                                      II-1
<PAGE>
    The indemnification provision in the Bylaws, and the indemnification
agreements entered into between the Registration and the Indemnitees, may be
sufficiently broad to permit indemnification of the Indemnitees for liabilities
arising under the Securities Act.
 
    The Registrant has agreed to indemnify the Underwriter and its officers,
directors, partners, employees, agents and controlling persons as to any losses,
claims, damages, expenses or liabilities arising out of any untrue statement or
omission of a material fact contained in the registration statement. The
Underwriter has agreed to indemnify the Registrant and its directors, officers
and controlling persons as to any losses, claims, damages, expenses or
liabilities arising out of any untrue statement or omission in the registration
statement based on information relating to the Underwriter furnished by it for
use in connection with the registration statement. See Section       of the
Underwriting Agreement which will be filed in an amendment as Exhibit 1.1 to
this Registration Statement.
 
    The Registrant has purchased directors' and officers' liability insurance.

*   To be filed by Amendment.
 
ITEM 17. UNDERTAKINGS.
 
    Insofar as indemnification for liabilities arising under the Securities Act
of 1933 (the "Securities Act") may be permitted to directors, officers and
controlling persons of the Registrant pursuant to the provisions described above
in Item 15, 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 whether
such indemnification by it is against public policy as expressed in the
Securities Act and will be governed by the final adjudication of such issue.
 
    The Registrant hereby also undertakes:
 
    (1) That, for purposes of determining any liability under the Securities Act
of 1933, the information omitted from the form of prospectus filed as part of a
registration statement in reliance upon Rule 430A
 
                                      II-2
<PAGE>
and contained in the 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 the registration statement as of the time it was declared effective.
 
    (2) That, 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.
 
    (3) To file, during any period in which it offers or sells securities, a
post-effective amendment to this registration statement to:
 
        (i) Include any prospectus required by section 10(a)(3) of the
    Securities Act;
 
        (ii) Include any additional or changed material information on the plan
    of distribution.
 
    (4) To file a post-effective amendment to remove from registration any of
the securities that remain unsold at the termination of the offering.
 
    (5) To deliver or cause to be delivered with the prospectus, to each person
to whom the prospectus is sent or given, the latest annual report to security
holders that is incorporated by reference in the prospectus and furnished
pursuant to and meeting the requirements of Rule 14a-3 or Rule 14c-3 under the
Securities Exchange Act of 1934; and, where interim financial information
required to be presented by Article 3 of Regulation S-X is not set forth in the
prospectus, to deliver, or cause to be delivered to each person whom the
prospectus is sent or given, the latest quarterly report that is specifically
incorporated by reference in the prospectus to provide such interim financial
information.

            Re:  REGISTRATION STATEMENT ON FORM S-3
 
Ladies and Gentlemen:
 
    You have requested our opinion in connection with the above-captioned
Registration Statement on Form S-3 to be filed by Chyron Corporation, a New York
corporation (the "Company"), with the Securities and Exchange Commission
pursuant to the Securities Act of 1933, as amended (the "Act"), and the rules
and regulations promulgated thereunder (the "Rules"). The Registration Statement
relates to the offering of up to 8,797,500 shares (the "Shares") of common
stock, par value $.01 per share (the "Common Stock").
 
    We have examined such records and documents and have made such examination
of law as we considered necessary to form a basis for the opinions set forth
herein. In our examination, we have assumed the genuineness of all signatures,
the authenticity of all documents submitted to us as originals, and the
conformity with the originals of all documents submitted to us as copies
thereof.
 
    Based upon such examination, it is our opinion that when there has been
compliance with the Act and applicable state securities laws and when the
Underwriting Agreement, a form of which will be filed as an exhibit to the
Registration Statement, is duly and validly executed and delivered, the Common
Stock, when issued, delivered and paid for in the manner described in such
Underwriting Agreement, will be validly issued, fully paid and nonassessable.
 
    We hereby consent to the filing of this opinion as an exhibit to the
Registration Statement and to the reference to our firm under the caption "Legal
Opinions" in the Registration Statement. In so doing, we do not admit that we
are in the category of persons whose consent is required under Section 7 of the
Act or under the Rules.
 
                                        Very truly yours,
 
                                        /s/  CAMHY KARLINSKY & STEIN LLP
