                                    HARMONIC

     Harmonic Inc. ("Harmonic" or the "Company") designs, manufactures and
markets digital and fiber optic systems for delivering video, voice and data
services over cable, satellite and wireless networks. Historically, almost all
of our sales have been derived directly or indirectly from sales of fiber optic
transmission systems to cable television operators. With the introduction of our
TRANsend digital headend products in 1997 and the subsequent purchase of New
Media Communication Ltd., which changed its name to Harmonic Data Systems Ltd.,
we broadened our product offering to enable delivery of digital video, voice and
data over satellite and wireless networks and cable systems.

     In order to further expand our digital systems capability, the Company
entered into an Agreement and Plan of Merger and Reorganization with C-Cube
Microsystems, Inc. ("C-Cube") on October 27, 1999, pursuant to which C-Cube
merged into Harmonic (the "Merger Agreement"). Under the terms of the Merger
Agreement, C-Cube spun off its semiconductor business as a separate publicly
traded company. C-Cube then merged into Harmonic and Harmonic therefore acquired
C-Cube's DiviCom business, which provides MPEG-2 encoding products and systems
for digital television. The merger was structured as a tax-free exchange of
stock and has been accounted for under the purchase method of accounting. In the
merger, each share of common stock of C-Cube was converted into 0.5427 shares of
Harmonic common stock. The purchase price, including merger-related costs, was
approximately $1.8 billion.

     The merger closed on May 3, 2000, and Harmonic has consolidated the results
of the DiviCom business in its financial statements from that date forward. The
merged company has been organized into two operating segments, Broadband Access
Networks ("BAN") for fiber optic systems and Convergent Systems ("CS") for
digital headend systems. While the two segments have been organized generally
around the pre-merger Harmonic fiber optics systems and the DiviCom digital
headend systems, respectively, these segments do not correspond to the
pre-merger companies in significant ways. For example, Harmonic's TRANsend and
CyberStream product lines are now part of the CS segment. Each of these segments
has its own separate management team, with a worldwide sales, sales support and
systems integration group supporting both segments.

                                  RISK FACTORS

     You should carefully consider the risks described below before making an
investment decision. The risks and uncertainties described below are not the
only ones facing our company. Additional risks and uncertainties not presently
known to us or that we currently deem immaterial may also impair our business
operations.

     If any of the following risks actually occur, our business, financial
condition or results of operations could be materially adversely affected. In
such case, the trading price of our common stock could decline and you could
lose all or part of your investment.

     This prospectus also contains forward-looking statements that involve risks
and uncertainties. Our actual results could differ materially from those
anticipated in these forward-looking statements as a result of certain factors,
including the risks faced by us described below and elsewhere in this
prospectus.

           QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK

     Market risk represents the risk of loss that may impact the financial
position, results of operations or cash flows of Harmonic due to adverse changes
in market prices and rates. Harmonic is exposed to market risk because of
changes in interest rates and foreign currency exchange rates as measured
against the U.S. Dollar and currencies of Harmonic's subsidiaries.

     From time to time Harmonic enters into contracts with customers which are
denominated in foreign currencies and which, if not hedged, expose Harmonic to
market risk from changes in foreign currency exchange rates. In addition,
Harmonic has subsidiaries in Israel and the United Kingdom which incur expenses
principally in local currencies, although sales are generally denominated in
U.S. dollars. While Harmonic does not anticipate that near-term changes in
exchange rates will have a material impact on future operating results, fair
values or cash flows, Harmonic cannot assure you that sudden and significant
changes in the value of foreign currencies, particularly the Israeli Shekel or
British Pound, would not harm Harmonic's financial condition and results of
operations.

     Harmonic's exposure to market risk for changes in interest rates relates
primarily to its investment portfolio of marketable debt securities of various
issuers, types and maturities. Harmonic does not use derivative instruments in
its investment portfolio, and its investment portfolio only includes highly
liquid instruments with an original maturity of less than two years. These
investments are classified as available for sale and the Company states its
investments at fair value, with unrealized gains and losses reported in other
comprehensive income. While Harmonic generally holds its investment securities
to maturity there is risk that losses could be incurred if it were to sell any
of its securities prior to maturity.

              FACTORS THAT MAY AFFECT FUTURE RESULTS OF OPERATIONS

OUR OPERATING RESULTS ARE LIKELY TO FLUCTUATE SIGNIFICANTLY AND MAY FAIL TO MEET
OR EXCEED THE EXPECTATIONS OF SECURITIES ANALYSTS OR INVESTORS, CAUSING OUR
STOCK PRICE TO DECLINE.

     Our operating results have fluctuated in the past and are likely to
continue to fluctuate in the future, on an annual and a quarterly basis, as a
result of several factors, many of which are outside of our control. Some of the
factors that may cause these fluctuations include:

     - the level of capital spending of our customers, both in the U.S. and in
       foreign markets;

     - changes in market demand;

     - the timing and amount of customer orders;

     - the timing of revenue from systems contracts which may span several
       quarters;

     - competitive market conditions;

                                        3
<PAGE>   5

     - our unpredictable sales cycles;

     - our ability to integrate the acquired DiviCom business into Harmonic's
       operations;

     - new product introductions by our competitors or by us;

     - changes in domestic and international regulatory environments;

     - market acceptance of new or existing products;

     - the cost and availability of components, subassemblies and modules;

     - the mix of our customer base and sales channels;

     - the mix of our products sold;

     - our development of custom products and software;

     - the level of international sales; and

     - economic conditions specific to the cable and satellite industries, and
       general economic conditions.

     In addition, we often recognize a substantial portion of our revenues in
the last month of the quarter. We establish our expenditure levels for product
development and other operating expenses based on projected sales levels, and
expenses are relatively fixed in the short term. Accordingly, variations in
timing of sales can cause significant fluctuations in operating results. In
addition, because a significant portion of our business is derived from orders
placed by a limited number of large customers, the timing of such orders can
also cause significant fluctuations in our operating results. Our expenses for
any given quarter are typically based on expected sales and if sales are below
expectations in any given quarter, the adverse impact of the shortfall on our
operating results may be magnified by our inability to adjust spending to
compensate for the shortfall. As a result of all these factors, our operating
results in one or more future periods may fail to meet or exceed the
expectations of securities analysts or investors. In that event, the trading
price of our common stock would likely decline. In this regard, due to lower
than expected sales to AT&T, and lower than expected sales in the CS segment, we
failed to meet our internal expectations as well as the expectations of
securities analysts and investors during the second quarter of 2000, and the
price of our common stock declined significantly.

WE DEPEND ON CABLE AND SATELLITE INDUSTRY CAPITAL SPENDING FOR A SUBSTANTIAL
PORTION OF OUR REVENUE AND ANY DECREASE OR DELAY IN CAPITAL SPENDING IN THESE
INDUSTRIES WOULD NEGATIVELY IMPACT OUR RESOURCES, OPERATING RESULTS AND
FINANCIAL CONDITION.

     Prior to the merger with C-Cube, almost all of Harmonic's historic sales
had been derived from sales to cable television operators and broadcasters, and
it expects these sales to constitute a substantial majority for the foreseeable
future. Almost all of the DiviCom business' historic sales have been derived
from sales to satellite operators, telephone companies and cable operators.
Demand for the combined company's products in the future will depend on the
magnitude and timing of capital spending by cable television operators,
broadcasters, satellite operators and telephone companies for constructing and
upgrading of their systems.

     These capital spending patterns are dependent on a variety of factors,
including:

     - access to financing;

     - annual budget cycles;

     - the status of federal, local and foreign government regulation of
       telecommunications and television broadcasting;

     - overall demand for communication services and the acceptance of new
       video, voice and data services;

     - evolving industry standards and network architectures;
                                        4
<PAGE>   6

     - competitive pressures;

     - discretionary customer spending patterns;

     - general economic conditions.

     In the past, specific factors contributing to reduced capital spending have
included:

     - uncertainty related to development of digital video and cable modem
       industry standards;

     - delays associated with the evaluation of new services and system
       architectures by many cable television operators;

     - emphasis on marketing and customer service strategies by cable television
       operators instead of construction of networks; and

     - general economic conditions in international markets.

     While our net sales increased during the last eight quarters from the level
achieved in the first quarter of 1998 due primarily to increased spending in the
North American cable television industry, spending by cable television operators
outside of North America generally remained weak. While net sales outside of
North America increased during the last three quarters compared to the first
quarter of 1998 we cannot predict if cable television spending outside of North
America will continue to grow. Although the Company's sales increased
significantly in the second quarter of 2000 compared to the first quarter of
2000, sales were below our expectations within each operating segment. BAN sales
were lower than expected and below the level achieved in the first quarter of
2000 due to reduced sales to AT&T, which have continued to decline from levels
achieved in the third quarter of 1999. For a more detailed discussion regarding
risks related to AT&T and other major customers, see "Our Customer Base Is
Concentrated And The Loss Of One Or More Of Our Key Customers Would Harm Our
Business. The Loss Of AT&T Or Any Other Key Customer Would Have A Negative
Effect On Our Business" below. The lower CS sales are due in part to slower
spending by satellite operators and to the impact of organizational changes
resulting from the C-Cube merger. The Company is unable to predict when cable
and satellite industry spending will increase. In addition, cable television
capital spending can be subject to the effects of seasonality, with fewer
construction and upgrade projects typically occurring in winter months and
otherwise being affected by inclement weather.

OUR CUSTOMER BASE IS CONCENTRATED AND THE LOSS OF ONE OR MORE OF OUR KEY
CUSTOMERS WOULD HARM OUR BUSINESS. THE LOSS OF AT&T OR ANY OTHER KEY CUSTOMER
WOULD HAVE A NEGATIVE EFFECT ON OUR BUSINESS.

     Historically, a significant majority of our sales and sales of DiviCom have
been to relatively few customers. Sales to Harmonic's ten largest customers in
1998, 1999 and the first half of 2000 accounted for approximately 66%, 75% and
61% of net sales, respectively. Due in part to the consolidation of ownership of
domestic cable television systems, we expect that sales to AT&T, RCN and
relatively few other customers will continue to account for a significant
percentage of net sales of the combined company for the foreseeable future. In
the second quarter of 2000, sales to AT&T accounted for 10% of our net sales
compared to 28% in the prior quarter and 40% in the second quarter of 1999.
Sales to AT&T have continued to decline from a record 52% of net sales in the
third quarter of 1999. We cannot assure you that sales to other customers will
compensate for any further reduction in sales to AT&T. Sales to RCN accounted
for 12% of our net sales in the second quarter of 2000 compared to 15% in the
prior quarter and less than 10% in the second quarter of 1999. Almost all of our
sales are made on a purchase order or system contract basis, and none of our
customers has entered into a long-term agreement requiring it to purchase our
products. The loss of, or any reduction in orders from, a significant customer
would harm our business.

WE HAVE EXPERIENCED DIFFICULTIES INTEGRATING THE DIVICOM BUSINESS OF C-CUBE.

     In addition to the risks generally associated with acquisitions, there are
a number of significant risks directly associated with our merger with C-Cube.
In particular, the successful combination of Harmonic
                                        5
<PAGE>   7

and C-Cube requires substantial attention from management. The anticipated
benefits of the merger will not be achieved unless the operations of the DiviCom
business of C-Cube are successfully combined with those of Harmonic in a timely
manner. To date, we have had difficulty in assimilating and integrating
disparate information systems and personnel into a combined corporation. These
difficulties are increased due to our limited personnel, management and other
resources. The successful combination of the two companies requires integration
of the companies' product offerings and the coordination of their research and
development and sales and marketing efforts. The process of combining the two
organizations has caused interruption of, and a loss of momentum in, the
activities of both of the organizations' businesses, and we believe that this
diversion may have caused certain customers to defer purchasing decisions. The
diversion of the attention of management from the day-to-day operations of the
combined company, or difficulties encountered in the transition and integration
process, could materially and adversely affect our business, financial condition
and operating results. In addition, our success depends, in part, on the
retention and integration of key management, technical, marketing, sales and
customer support personnel of the DiviCom business, and, in particular, the
retention of these key employees during the transitional period following the
merger. We have experienced the loss of certain key employees since the merger,
principally due to intense competition for qualified technical and other
personnel in the San Francisco Bay Area. The loss of key employees and managers
has adversely affected the acquired DiviCom business and could continue to
adversely affect our business and operating results.

WE DEPEND ON OUR INTERNATIONAL SALES AND ARE SUBJECT TO THE RISKS ASSOCIATED
WITH INTERNATIONAL OPERATIONS, WHICH MAY NEGATIVELY AFFECT OUR PROFITABILITY.

     Sales to customers outside of the United States in 1998, 1999 and first
half of 2000 represented 43%, 30% and 35% of net sales, respectively, and we
expect that international sales will continue to represent a substantial portion
of our net sales for the foreseeable future. Our international operations are
subject to a number of risks, including:

     - changes in foreign government regulations and telecommunications
       standards;

     - import and export license requirements, tariffs, taxes and other trade
       barriers;

     - fluctuations in currency exchange rates;

     - difficulty in collecting accounts receivable;

     - the burden of complying with a wide variety of foreign laws, treaties and
       technical standards;

     - difficulty in staffing and managing foreign operations; and

     - political and economic instability.

     While our international sales are typically denominated in U.S. dollars,
fluctuations in currency exchange rates could cause our products to become
relatively more expensive to customers in a particular country, leading to a
reduction in sales or profitability in that country. Gains and losses on the
conversion to U.S. dollars of accounts receivable, accounts payable and other
monetary assets and liabilities arising from international operations may
contribute to fluctuations in operating results. Furthermore, payment cycles for
international customers are typically longer than those for customers in the
United States. Unpredictable sales cycles could cause us to fail to meet or
exceed the expectations of security analysts and investors for any given period.
Further, foreign markets may not continue to develop.

WE MUST BE ABLE TO MANAGE EXPENSES AND INVENTORY RISKS ASSOCIATED WITH MEETING
THE DEMAND OF OUR CUSTOMERS.

     From time to time, we receive indications from our customers as to their
future plans and requirements to ensure that we will be prepared to meet their
demand for our products. In the past, however, we have received such indications
but, on occasion, we did not ultimately receive purchase orders for our
products. We must be able to effectively manage expenses and inventory risks
associated with meeting potential demand for our products. In addition, if we
fail to meet customers' supply expectations,
                                        6
<PAGE>   8

we may lose business from such customers. If we expend resources and purchase
materials to manufacture products and such products are not purchased, our
business and operating results could suffer.

THE MARKETS IN WHICH WE OPERATE ARE INTENSELY COMPETITIVE AND MANY OF OUR
COMPETITORS ARE LARGER AND MORE ESTABLISHED.

     The markets for cable television fiber optics systems and digital video
broadcasting systems are extremely competitive and have been characterized by
rapid technological change and declining average selling prices. Harmonic's
competitors in the cable television fiber optics systems business include
significantly larger corporations such as ADC Telecommunications, ANTEC, a
company owned in part by AT&T, General Instrument, which has been acquired by
Motorola, Philips and Scientific-Atlanta. Additional competition could come from
new entrants in these markets, such as Lucent Technologies and Cisco Systems.

     In the digital and video broadcasting systems business, we compete with
vertically integrated system suppliers including Motorola, Scientific-Atlanta,
Tandberg, Thomson Broadcast Systems and Philips, as well as more specialized
suppliers including SkyStream and Terayon.

     Most of our competitors are substantially larger and have greater
financial, technical, marketing and other resources than Harmonic. Many of these
large organizations are in a better position to withstand any significant
reduction in capital spending by customers in these markets. They often have
broader product lines and market focus and will therefore not be as susceptible
to downturns in a particular market. In addition, many of our competitors have
been in operation longer than we have and therefore have more long standing and
established relationships with domestic and foreign customers. We may not be
able to compete successfully in the future and competition may harm our
business.

     If any of our competitors' products or technologies were to become the
industry standard, our business could be seriously harmed. For example, U.S.
cable operators have to date mostly purchased proprietary digital systems from
Motorola and Scientific-Atlanta. While certain operators have made limited
purchases of the "open" systems provided by Harmonic, we cannot assure you that
our digital products will find broad market acceptance with U.S. cable
operators. In addition, companies that have historically not had a large
presence in the broadband communications equipment market have begun recently to
expand their market share through mergers and acquisitions. The continued
consolidation of our competitors could have a significant negative impact on us.
Further, our competitors, particularly competitors of our digital and video
broadcasting systems' business may bundle their products or incorporate
functionality into existing products in a manner that discourages users from
purchasing our products or which may require us to lower our selling prices
resulting in lower gross margins.

BROADBAND COMMUNICATIONS MARKETS ARE RELATIVELY IMMATURE AND CHARACTERIZED BY
RAPID TECHNOLOGICAL CHANGE.

     Broadband communications markets are relatively immature, making it
difficult to accurately predict the markets' future growth rates, sizes or
technological directions. In view of the evolving nature of these markets, it is
possible that cable television operators, telephone companies or other suppliers
of broadband wireless and satellite services will decide to adopt alternative
architectures or technologies that are incompatible with our current or future
products. If we are unable to design, develop, manufacture and sell products
that incorporate or are compatible with these new architectures or technologies,
our business will suffer.

                                        7
<PAGE>   9

WE NEED TO DEVELOP AND INTRODUCE NEW AND ENHANCED PRODUCTS IN A TIMELY MANNER TO
REMAIN COMPETITIVE.

     Broadband communications markets are characterized by continuing
technological advancement, changes in customer requirements and evolving
industry standards. To compete successfully, we must design, develop,
manufacture and sell new or enhanced products that provide increasingly higher
levels of performance and reliability. However, we may not be able to
successfully develop or introduce these products, if our products:

     - are not cost effective,

     - are not brought to market in a timely manner,

     - are not in accordance with evolving industry standards and architectures,
       or

     - fail to achieve market acceptance.

     In addition, to successfully develop and market our planned products for
digital applications, we will be required to retain and attract new personnel
with experience and expertise in the digital arena. Competition for qualified
personnel is intense. We may not be successful in retaining and attracting
qualified personnel.

     Also, to successfully develop and market certain of our planned products
for digital applications, we may be required to enter into technology
development or licensing agreements with third parties. We cannot assure you
that we will be able to enter into any necessary technology development or
licensing agreement on terms acceptable to us, or at all. The failure to enter
into technology development or licensing agreements when necessary could limit
our ability to develop and market new products and, accordingly, could
materially and adversely affect our business and operating results.

WE NEED TO EFFECTIVELY MANAGE OUR GROWTH.

     The growth in our business has placed, and is expected to continue to
place, a significant strain on our personnel, management and other resources.
Our ability to manage any future growth effectively will require us to attract,
train, motivate and manage new employees successfully, to integrate new
employees into our overall operations, to retain key employees and to continue
to improve our operational, financial and management systems. If we fail to
manage our future growth effectively, our business could suffer.

COMPETITION FOR QUALIFIED PERSONNEL IS INTENSE, AND WE MAY NOT BE SUCCESSFUL IN
ATTRACTING AND RETAINING PERSONNEL.

     Our future success will depend, to a significant extent, on the ability of
our management to operate effectively, both individually and as a group. We are
dependent on our ability to retain and motivate high caliber personnel, in
addition to attracting new personnel. Competition for qualified technical and
other personnel is intense, particularly in the San Francisco Bay Area and
Israel, and we may not be successful in attracting and retaining such personnel.

     Competitors and others have in the past and may in the future attempt to
recruit our employees. While our employees are required to sign standard
agreements concerning confidentiality and ownership of inventions, we generally
do not have employment contracts or noncompetition agreements with any of our
personnel. The loss of the services of any of our key personnel, the inability
to attract or retain qualified personnel in the future or delays in hiring
required personnel, particularly engineers and other technical personnel, could
negatively affect our business.

THE C-CUBE MERGER HAS RESULTED IN THE RECORDING OF SUBSTANTIAL GOODWILL AND
OTHER INTANGIBLE ASSETS AND REPORTING OF SUBSTANTIAL NET LOSSES WITHOUT ANY
CORRESPONDING TAX DEDUCTION.

     Goodwill and other intangible assets of approximately $1.7 billion were
recorded in connection with the merger as disclosed in Note 7 to the unaudited
Condensed Consolidated Financial Statements for the three months ended June 30,
2000. Goodwill and intangibles are being amortized over 5 years, and this

                                        8
<PAGE>   10

amortization is expected to result in substantial net losses over the
amortization period. The amortization of goodwill and intangibles are not
deductible for tax purposes which will result in a provision for income taxes
despite a substantial reported net loss.

WE ARE LIABLE FOR C-CUBE'S PRE-MERGER TAX LIABILITIES, INCLUDING TAX LIABILITIES
RESULTING FROM THE SPIN-OFF OF ITS SEMICONDUCTOR BUSINESS.

     The spin-off of C-Cube's semiconductor business gave rise to a significant
tax liability of approximately $320 million based on a valuation of the
semiconductor business of $1.1 billion. This liability is payable on or before
August 15, 2000. C-Cube determined the valuation by using the volume weighted
average price on May 3, 2000, the first trading day following the spin-off,
which resulted in a share price of $21.74. Under state law, Harmonic generally
is liable for all of C-Cube's debts, including C-Cube's liability for taxes
resulting from the spin-off. C-Cube retained and transferred to Harmonic in the
merger an amount of cash and other consideration sufficient to pay this
liability as well as all other tax liabilities of C-Cube and its subsidiaries
for periods prior to the merger. Harmonic will also be indemnified by the
spun-off semiconductor business if the cash reserves are not sufficient to
satisfy all of C-Cube's tax liabilities for periods prior to the merger. If for
any reason, the spun-off semiconductor business does not have sufficient cash to
pay such taxes, or if there are additional taxes due with respect to the non-
semiconductor business, Harmonic generally will remain liable, and such
liability could have a material adverse effect on Harmonic.

DUE TO THE STRUCTURE OF THE MERGER TRANSACTION, HARMONIC IS LIABLE FOR C-CUBE'S
GENERAL PRE-MERGER LIABILITIES AND ANY LIABILITIES RELATING TO C-CUBE'S
SEMICONDUCTOR BUSINESS FOR WHICH THE SPUN-OFF SEMICONDUCTOR BUSINESS IS UNABLE
TO INDEMNIFY HARMONIC.

     The merger of C-Cube into Harmonic, with Harmonic as the surviving entity,
resulted in our assuming all of the liabilities of C-Cube at the time of the
merger. Pursuant to the merger agreement, Harmonic is indemnified by the
spun-off semiconductor business for liabilities associated with C-Cube's
historic semiconductor business. However, if the spun-off semiconductor business
is unable to fulfill its indemnification obligations to Harmonic or if general
liability claims not specifically associated with C-Cube's historic
semiconductor business are asserted, we would have to assume such obligations.
Those obligations could have a material adverse effect on us.

WE MAY BE SUBJECT TO RISKS ASSOCIATED WITH OTHER ACQUISITIONS.

     We have made and may make investments in complementary companies, products
or technologies. If we make acquisitions, we could have difficulty assimilating
or retaining the acquired companies' personnel and operations or integrating the
acquired technology or products into ours. These difficulties could disrupt our
ongoing business, distract our management and employees and increase our
expenses. Moreover, our profitability may suffer because of acquisition-related
costs or amortization costs for acquired goodwill and other intangible assets.
Furthermore, we may have to incur debt or issue equity securities to pay for any
future acquisitions, the issuance of which could be dilutive to our existing
shareholders. If we are unable to successfully address any of these risks, our
business, financial condition and operating results could be harmed.

DIFFICULTIES IN THE DEVELOPMENT AND PRODUCTION OF VIDEO ENCODING CHIPS BY
C-CUBE'S SPUN-OFF SEMICONDUCTOR BUSINESS MAY ADVERSELY IMPACT US.

     The DiviCom business and C-Cube semiconductor business collaborated on the
production and development of two video encoding microelectronic chips prior to
the merger. In connection with the merger, Harmonic and the spun-off
semiconductor business entered into a contractual relationship under which
Harmonic will have access to certain of the spun-off semiconductor business
technologies and products which the DiviCom business previously depended on for
its product and service offerings. However, under the contractual relationships
between Harmonic and the spun-off semiconductor business, the semiconductor
business does not have a firm commitment to continue the development of video
                                        9
<PAGE>   11

encoding microelectronic chips. As a result, the semiconductor business may
choose not to continue future development of the chips for any reason. The
semiconductor business may also encounter in the future technological
difficulties in the production and development of the chips. If the spun-off
semiconductor business is not able to or does not sustain its development and
production efforts in this area, we may not be able to fully recognize the
benefits of the acquisition. See "Supply, License and Development Agreement" at
page 60 of the joint proxy statement filed with the Securities and Exchange
Commission on March 23, 2000, for further details of Harmonic's business
relationship with the spun-off semiconductor business after the merger.

IF SALES FORECASTED FOR A PARTICULAR PERIOD ARE NOT REALIZED IN THAT PERIOD DUE
TO THE UNPREDICTABLE SALES CYCLES OF OUR PRODUCTS, OUR OPERATING RESULTS FOR
THAT PERIOD WILL BE HARMED.

     The sales cycles of many of our products, particularly our newer products
and products sold internationally, are typically unpredictable and usually
involve:

     - a significant technical evaluation;

     - a commitment of capital and other resources by cable, satellite, and
       other network operators;

     - delays associated with cable, satellite, and other network operators'
       internal procedures to approve large capital expenditures;

     - time required to engineer the deployment of new technologies or services
       within broadband networks; and

     - testing and acceptance of new technologies that affect key operations.

     For these and other reasons, our sales cycles generally last three to six
months, but can last up to 12 months. If orders forecasted for a specific
customer for a particular quarter do not occur in that quarter, our operating
results for that quarter could be substantially lower than anticipated.

     As a result of the merger, a significant portion of our revenue will be
derived from solutions contracts. A substantial part of the CS Division's
revenues are from solutions contracts which include a combination of product
sales as well as design, installation and integration services. Revenue
forecasts are based on estimated timing of the systems design, installation and
integration. Because the solutions contracts on the average span three quarters,
the timing of revenue is difficult to predict and could result in lower than
expected revenue in any particular quarter.

OUR FAILURE TO ADEQUATELY PROTECT OUR PROPRIETARY RIGHTS MAY ADVERSELY AFFECT
US.

     We currently hold 29 issued United States patents and 9 issued foreign
patents, and have a number of patent applications pending. Although we attempt
to protect our intellectual property rights through patents, trademarks,
copyrights, licensing arrangements, maintaining certain technology as trade
secrets and other measures, we cannot assure you that any patent, trademark,
copyright or other intellectual property rights owned by us will not be
invalidated, circumvented or challenged, that such intellectual property rights
will provide competitive advantages to us or that any of our pending or future
patent applications will be issued with the scope of the claims sought by us, if
at all. We cannot assure you that others will not develop technologies that are
similar or superior to our technology, duplicate our technology or design around
the patents that we own. In addition, effective patent, copyright and trade
secret protection may be unavailable or limited in certain foreign countries in
which we do business or may do business in the future.

     We believe that the future success of our business will depend on our
ability to translate the technological expertise and innovation of our personnel
into new and enhanced products. We generally enter into confidentiality or
license agreements with our employees, consultants, vendors and customers as
needed, and generally limit access to and distribution of our proprietary
information. Nevertheless, we cannot assure you that the steps taken by us will
prevent misappropriation of our technology. In addition, we have taken in the
past, and may take in the future, legal action to enforce our patents and other
                                       10
<PAGE>   12

intellectual property rights, to protect our trade secrets, to determine the
validity and scope of the proprietary rights of others, or to defend against
claims of infringement or invalidity. Such litigation could result in
substantial costs and diversion of resources and could harm our business and
operating results.

     In order to successfully develop and market certain of our planned products
for digital applications, we may be required to enter into technology
development or licensing agreements with third parties. Although many companies
are often willing to enter into such technology development or licensing
agreements, we cannot assure you that such agreements will be negotiated on
terms acceptable to us, or at all. The failure to enter into technology
development or licensing agreements, when necessary, could limit our ability to
develop and market new products and could cause our business to suffer.

     As is common in our industry, we have from time to time received
notification from other companies of intellectual property rights held by those
companies upon which our products may infringe. Any claim or litigation, with or
without merit, could be costly, time consuming and could result in a diversion
of management's attention, which could harm our business. If we were found to be
infringing on the intellectual property rights of any third party, we could be
subject to liabilities for such infringement, which could be material, and could
be required to seek licenses from other companies or to refrain from using,
manufacturing or selling certain products or using certain processes. Although
holders of patents and other intellectual property rights often offer licenses
to their patent or other intellectual property rights, we cannot assure you that
licenses would be offered, that the terms of any offered license would be
acceptable to us or that failure to obtain a license would not cause our
operating results to suffer.

WE PURCHASE SEVERAL KEY COMPONENTS, SUBASSEMBLIES AND MODULES USED IN THE
MANUFACTURE OR INTEGRATION OF OUR PRODUCTS FROM SOLE OR LIMITED SOURCES, AND WE
ARE INCREASINGLY DEPENDENT ON CONTRACT MANUFACTURERS.

     Many components, subassemblies and modules necessary for the manufacture or
integration of our products are obtained from a sole supplier or a limited group
of suppliers. Our reliance on sole or limited suppliers, particularly foreign
suppliers, and our increasing reliance on subcontractors involves several risks,
including a potential inability to obtain an adequate supply of required
components, subassemblies or modules and reduced control over pricing, quality
and timely delivery of components, subassemblies or modules. In particular,
certain optical components have been recently in short supply and are available
only from a small number of suppliers, including sole source suppliers. While we
expend considerable efforts to qualify additional optical component sources,
consolidation of suppliers in the industry (including the acquisition of Etek
Dynamics and the proposed acquisition of SDL Inc. by JDS Uniphase) and the small
number of viable alternatives have limited the results of these efforts. Certain
key elements of our digital headend products are provided by a sole foreign
supplier. We do not generally maintain long-term agreements with any of our
suppliers or subcontractors. An inability to obtain adequate deliveries or any
other circumstance that would require us to seek alternative sources of supply
could affect our ability to ship our products on a timely basis, which could
damage relationships with current and prospective customers and harm our
business. We attempt to limit this risk by maintaining safety stocks of these
components, subassemblies and modules. As a result of this investment in
inventories, we may be subject to an increasing risk of inventory obsolescence
in the future, which could harm our business.

WE MAY NEED ADDITIONAL CAPITAL IN THE FUTURE AND MAY NOT BE ABLE TO SECURE
ADEQUATE FUNDS ON TERMS ACCEPTABLE TO US.

     We currently anticipate that our existing cash balances including cash
received pursuant to the merger, and available line of credit and cash flow
expected to be generated from future operations will be sufficient to meet our
liquidity needs for at least the next twelve months. However, we may need to
raise additional funds if our estimates change or prove inaccurate or in order
for us to respond to unforeseen technological or marketing hurdles or to take
advantage of unanticipated opportunities.

     In addition, we expect to review other potential acquisitions that would
complement our existing product offerings or enhance our technical capabilities.
While we have no other current agreements or

                                       11
<PAGE>   13

negotiations underway with respect to any potential acquisition, any future
transaction of this nature could require potentially significant amounts of
capital. Funds may not be available at the time or times needed, or available on
terms acceptable to us. If adequate funds are not available, or are not
available on acceptable terms, we may not be able to take advantage of market
opportunities, to develop new products or to otherwise respond to competitive
pressures.

WE FACE RISKS ASSOCIATED WITH HAVING IMPORTANT FACILITIES AND RESOURCES LOCATED
IN ISRAEL.

     Harmonic maintains two facilities in the State of Israel with a total of
approximately 90 employees. The personnel at these facilities represent a
significant portion of our research and development operations. Accordingly, we
are directly influenced by the political, economic and military conditions
affecting Israel, and any major hostilities involving Israel or the interruption
or curtailment of trade between Israel and its present trading partners could
significantly harm our business.

     In addition, most of our employees in Israel are currently obligated to
perform annual reserve duty in the Israel Defense Forces and are subject to
being called for active military duty at any time. We cannot predict the effect
of these obligations on Harmonic in the future.

SECURITIES CLASS ACTION CLAIMS.

     On June 28, 2000, a securities class action captioned Smith v. Harmonic
Inc., Et. Al., Civil Action No. C-00-2287-PJH was filed against Harmonic and
several of its officers and directors in the United States District Court for
the Northern District of California. Additional actions containing similar
allegation have since been filed. These complaints allege violations of the
federal securities laws, specifically Section 10(b) of the Securities Exchange
Act of 1934, and seek unspecified damages on behalf of a purported class of
purchasers of Harmonic common stock during the period from March 27, 2000
through June 26, 2000. The various actions have not yet been consolidated and no
trial date has been scheduled.

     On June 29, 2000, a securities class action captioned Krim v. Harmonic
Inc., Et. Al., Civil Action No. CV 790816 was filed against Harmonic and several
of its officers and directors in the California Superior Court for the County of
Santa Clara. The complaint alleges violations of the federal securities laws,
specifically Section 11 of the Securities Act of 1933, and seeks unspecified
damages on behalf of a purported class of persons who acquired Harmonic common
stock pursuant to a Form S-4 Registration Statement filed March 23, 2000,
concerning a transaction completed on May 3, 2000. On July 26, 2000, the action
was removed to the United States District Court for the Northern District of
California. No trial date has been scheduled.

     While the Company believes these class actions to be without merit and is
vigorously defending against them, there can be no assurance that the Company
will prevail. An unfavorable outcome of this litigation could have a material
adverse effect on the Company's consolidated financial position, liquidity or
results of operations.

OUR STOCK PRICE MAY BE VOLATILE.

     The market price of our common stock has fluctuated in the past and is
likely to fluctuate in the future. In addition, the securities markets have
experienced significant price and volume fluctuations and the market prices of
the securities of technology companies have been especially volatile. Investors
may be unable to resell their shares of our common stock at or above their
purchase price. In the past, companies that have experienced volatility in the
market price of their stock have been the object of securities class action
litigation.

     We are currently the object of securities class action litigation, and this
could result in substantial costs and a diversion of management's attention and
resources.

     While the Company believes these class actions to be without merit and is
vigorously defending against them, there can be no assurance that the Company
will prevail. An unfavorable outcome of this
                                       12

litigation could have a material adverse effect on the Company's consolidated
financial position, liquidity or results of operations.

OUR CERTIFICATE OF INCORPORATION AND BYLAWS AND DELAWARE LAW CONTAIN PROVISIONS
THAT COULD DISCOURAGE A TAKEOVER.

     Provisions of our Amended and Restated Certificate of Incorporation,
Bylaws, and Delaware law could make it more difficult for a third party to
acquire us, even if doing so would be beneficial to our stockholders.

                              PLAN OF DISTRIBUTION

     The shares covered by this prospectus may be offered and sold from time to
time by the selling stockholders. The selling stockholders will act
independently of Harmonic in making decisions with respect to the timing, manner
and size of each sale. The selling stockholders may sell the shares being
offered hereby on the Nasdaq National Market, or otherwise, at prices and under
terms then prevailing or at prices related to the then current market price, at
varying prices or at negotiated prices. The shares offered hereby may be sold,
without limitation, by one or more of the following means of distribution: (a) a
block trade in which the broker-dealer so engaged will attempt to sell such
shares as agent, but may position and resell a portion of the block as principal
to facilitate the transaction; (b) purchases by a broker-dealer as principal and
resale by such broker-dealer for its own account pursuant to this prospectus;
(c) an over-the-counter distribution in accordance with the rules of the Nasdaq
National Market; (d) ordinary brokerage transactions and transactions in which
the broker solicits purchasers; and (e) in privately negotiated transactions. To
the extent required, this prospectus may be amended and supplemented from time
to time to describe a specific plan of distribution.

     In connection with distributions of the shares offered hereby or otherwise,
the selling stockholders may enter into hedging transactions with broker-dealers
or other financial institutions. In connection with such transactions,
broker-dealers or other financial institutions may engage in short sales of
Harmonic's common stock in the course of hedging the positions they assume with
selling stockholders. The selling stockholders may also sell Harmonic's common
stock short and deliver the shares offered hereby to close out such short
positions. The selling stockholders may also enter into option or other
transactions with broker-dealers or other financial institutions which require
the delivery to such broker-dealer or other financial institution of shares
offered hereby, which shares such broker-dealer or other financial institution
may resell pursuant to this prospectus (as supplemented or amended to reflect
such transaction). The selling stockholders may also pledge the shares offered
hereby to a broker-dealer or other financial institution, and, upon a default,
such broker-dealer or other financial institution, may effect sales of the
pledged shares pursuant to this prospectus (as supplemented or amended to
reflect such transaction). In addition, any shares offered hereby that qualify
for sale pursuant to Rule 144 may, at the option of the holder thereof, be sold
under Rule 144 rather than pursuant to this prospectus.

     Any broker-dealer participating in such transactions as agent may receive
commissions from the selling stockholder and/or purchasers of the shares offered
hereby (and, if it acts as agent for the purchaser of such shares, from such
purchaser). Usual and customary brokerage fees will be paid by the selling
stockholder. Broker-dealers may agree with the selling stockholder to sell a
specified number of shares at a stipulated price per share, and, to the extent
such a broker-dealer is unable to do so acting as

                                       15
<PAGE>   17

agent for the selling stockholder, to purchase as principal any unsold shares at
the price required to fulfill the broker-dealer commitment to the selling
stockholder. Broker-dealers who acquire shares as principal may thereafter
resell such shares from time to time in transactions (which may involve cross
and block transactions and which may involve sales to and through other
broker-dealers, including transactions of the nature described above) in the
over-the-counter market, in negotiated transactions or otherwise at market
prices prevailing at the time of sale or at negotiated prices, and in connection
with such resales, may pay to or receive from the purchasers of such shares
commissions computed as described above.

     To comply with the securities laws of certain states, if applicable, the
shares offered hereby will be sold in such jurisdictions only through registered
or licensed brokers or dealers. In addition, in certain states the shares
offered hereby may not be sold unless they have been registered or qualified for
sale in the applicable state or an exemption from the registration or
qualification requirement is available and is complied with.

     We have advised the selling stockholders that the anti-manipulation rules
of Regulation M under the Exchange Act may apply to sales of the shares offered
hereby in the market and to the activities of the selling stockholders and their
affiliates. In addition, we will make copies of this prospectus available to the
selling stockholders and have informed them of the need for delivery of copies
of this prospectus to purchasers at or prior to the time of any sale of the
shares offered hereby. The selling stockholders may indemnify any broker-dealer
than participates in transactions involving the sale of the shares against
certain liabilities, including liabilities arising under the Securities Act.

     Some of the selling stockholders may distribute their shares, from time to
time, to their limited and/or general partners, who may sell shares pursuant to
this prospectus. Each selling shareholder may also transfer shares owned by him
by gift, and upon any such transfer the donee would have the same right of sale
as the selling stockholder.

     At the time a particular offer of shares is made, if required, a prospectus
supplement will be distributed that will set forth the number of shares being
offered and the terms of the offering, including the name of any underwriter,
dealer or agent, the purchase price paid by any underwriter, any discount,
commission and other item constituting compensation, any discount, commission or
concession allowed or reallowed or paid to any dealer, and the proposed selling
price to the public.

                   INDEMNIFICATION OF DIRECTORS AND OFFICERS

     Our Bylaws limits the liability of our directors and officers for expenses
to the maximum extent permitted by Delaware law. Delaware law provides that
directors of a corporation will not be personally liable for monetary damages
for breach of their fiduciary duties as directors, except for liability (i) for
any breach of their duty of loyalty to the corporation or its stockholders; (ii)
for acts or omissions not in good faith or that involve intentional misconduct
or a knowing violation of law; (iii) for unlawful payments of dividends or
unlawful stock repurchases or redemptions as provided in Section 174 of the
Delaware General Corporation Law; or (iv) for any transaction from which the
director derived an improper personal benefit.

     Our Certificate of Incorporation provides that we must indemnify our
directors and may indemnify our other officers, employees and agents to the
fullest extent permitted by law.

     We have entered into agreements to indemnify our directors and officers, in
addition to indemnification provided for in our Bylaws. These agreements, among
other things, indemnify our directors and officers for certain expenses
(including attorneys' fees), judgments, fines and settlement amounts incurred by
any such person in any action or proceeding, including any action by or in the
right of Harmonic, arising out of such person's services as a Harmonic director
or officer, any subsidiary of Harmonic or any other company or enterprise to
which the person provides services at our request.

     Harmonic's Bylaws also permit us to secure insurance on behalf of any
officer, director, employee or other agent for any liability arising out of his
or her actions in such capacity, regardless of whether the

                                       16
<PAGE>   18

Bylaws would permit indemnification. We also maintain an insurance policy
insuring our directors and officers against liability for certain acts and
omissions while acting in their official capacities.

     Insofar as indemnification for liabilities arising under the Securities Act
of 1933 may be permitted to directors, officers or persons controlling Harmonic
pursuant to the foregoing provisions, we have been informed 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.

                                 LEGAL MATTERS

     Certain legal matters relating to the validity of the securities offered
hereby will be passed upon for Harmonic by Wilson Sonsini Goodrich & Rosati,
Professional Corporation, Palo Alto, California.
