ITEM 5. OTHER EVENTS

        Broadcom Corporation ("Broadcom" or the "Company") filed a Current
Report on Form 8-K dated August 31, 1999 to report its acquisitions on that date
of HotHaus Technologies Inc. ("HotHaus") and AltoCom, Inc. ("AltoCom"). These
acquisitions were accounted for using the pooling-of-interests method of
accounting. We are amending the Report to restate our historical consolidated
financial statements to reflect the pooled operations of HotHaus and AltoCom.
There are no other changes to the Report as filed. The restated historical
consolidated financial statements also include the pooled operations of the
Company's prior acquisitions.

        The following consolidated financial statements of Broadcom, as restated
to reflect the pooled transactions, are filed as part of this Report:

1. Selected Consolidated Financial Data for the five years ended December 31,
   1998

2. Management's Discussion and Analysis of Financial Condition and Results of
   Operations for the years ended December 31, 1998, 1997 and 1996

3. Report of Independent Auditors

4. Consolidated Balance Sheets as of December 31, 1998 and 1997

5. Consolidated Statements of Operations for the years ended December 31, 1998,
   1997 and 1996

6. Consolidated Statements of Shareholders' Equity for the years ended December
   31, 1998, 1997 and 1996

7. Consolidated Statements of Cash Flows for the years ended December 31, 1998,
   1997 and 1996

8. Notes to Consolidated Financial Statements

9. Financial Statement Schedule of Consolidated Valuation and Qualifying
   Accounts

        The restated consolidated financial statements give effect to the
business combinations as if they had occurred prior to the beginning of each
period presented and reflect adjustments made to (i) conform the accounting
policies of the combined companies and (ii) eliminate intercompany accounts and
transactions. No adjustments have been made to give effect to
acquisition-related expenses, which have been recorded in the fiscal year ending
December 31, 1999.

MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF
OPERATIONS FOR THE FISCAL YEARS ENDED DECEMBER 31, 1998, 1997 AND 1996

CAUTIONARY STATEMENT

        This Current Report on Form 8-K contains forward-looking statements
based on our current expectations, estimates and projections about our industry,
management's beliefs, and certain assumptions made by us. Words such as
"anticipates," "expects," "intends," "plans," "believes," "seeks," "estimates,"
"may," "will" and variations of these words or similar expressions are intended
to identify forward-looking statements. In addition, any statements that refer
to expectations, projections or other characterizations of future events or
circumstances, including any underlying assumptions, are forward-looking
statements. Such statements include, but are not limited to, statements
concerning projected revenues, expenses and gross profit, the need for
additional capital, Year 2000 compliance, market acceptance of our products, our
ability to consummate acquisitions and integrate their operations successfully,
our ability to achieve further integration, the status of evolving technologies
and their growth potential, our production capacity, our ability to migrate to
smaller process geometries, and the success of pending litigation. Such
statements are not guarantees of future performance and are subject to certain
risks, uncertainties and assumptions that are difficult to predict. Therefore,
our actual results could differ materially and adversely from those expressed in
any forward-looking statements as a result of various factors.

        The section entitled "Risk Factors" set forth in this Report and similar
discussions in our other SEC filings, discuss some of the important risk factors
that may affect our business, results of operations and financial condition. You
should carefully consider those risks, in addition to the other information in
this Report and in our other filings with the SEC, before deciding to invest in
our company or to maintain or increase your investment. We undertake no
obligation to revise or update publicly any forward-looking statements for any
reason.

        The information contained in this Form 8-K is not a complete description
of our business or the risks associated with an investment in our common stock.
We urge you to carefully review and consider the various disclosures made by us
in this Report and in our other reports filed with the SEC, including our Annual
Report on Form 10-K for the year ended December 31, 1998, and our subsequent
reports on Forms 10-Q and 8-K, that discuss our business in greater detail and
advise interested parties of certain additional risks, uncertainties and other
factors that may affect our business, results of operations or financial
condition.

        All share numbers and per share amounts in this Report have been
retroactively adjusted to reflect our 2-for-1 stock split, in the form of a 100%
stock dividend, effective February 17, 1999.

OVERVIEW

        We are a leading provider of highly integrated silicon solutions that
enable broadband digital transmission of voice, data and video content to and
throughout the home and within the business enterprise. Our products enable the
high-speed transmission of data over existing communications infrastructures,
most of which were not originally intended for digital data transmission. Using
proprietary technologies and advanced design methodologies, we design, develop
and supply integrated circuits for a number of the most significant broadband
communications markets, including the markets for cable set-top boxes, cable
modems, high-speed office networks, home networking, direct broadcast satellite
and terrestrial digital broadcast, and digital subscriber lines. From our
inception in 1991 through 1994, we were primarily engaged in product development
and the establishment of strategic customer and foundry relationships. During
that period, we generated the majority of our revenue from development work
performed for key customers. We began shipping our products in 1994, and
subsequently our revenue has grown predominately through sales of our
semiconductor products. We intend to continue to enter into development
contracts with key customers, but expect that development revenue will
constitute a decreasing percentage of our total revenue. We also generate a
small percentage of our product revenue from sales of software and software
support and sales of system level reference designs.

        We recognize product revenue at the time of shipment. Provision is
concurrently made for estimated product returns, which historically have been
immaterial. Our products typically carry a one-year warranty. We recognize
development revenue when earned. Revenue from licensed software is recognized at
the time of shipment, provided that we have vendor-specific objective evidence
of the fair value of each element of the software offering. Revenue from
post-contract customer support and any other future deliverables is deferred and
earned over the support period or as contract elements are delivered.


                                       4
<PAGE>   5

        The percent of our revenue derived from independent customers located
outside of the United States was approximately 17.2% in 1998, 19.6% in 1997 and
19.8% in 1996. All of our revenue to date has been denominated in U.S. dollars.
See Note 10 of Notes to Consolidated Financial Statements.

        From time to time, our key customers have placed large orders causing
our quarterly revenue to fluctuate significantly. We expect these fluctuations
will continue in the future. Sales to our five largest customers, including
sales to their respective manufacturing subcontractors, represented
approximately 74.2% of our revenue in 1998, 56.2% of our revenue in 1997 and
60.6% of our revenue in 1996. We expect that our key customers will continue to
account for a significant portion of our revenue for 1999 and in the future.

        Our gross margin has been affected in the past, and may continue to be
affected in the future, by various factors, including, but not limited to, the
following:

        o our product mix;

        o the position of our products in their respective life cycles;

        o competitive pricing strategies;

        o the mix of product revenue and development revenue; and

        o manufacturing cost efficiencies and inefficiencies.

For example, newly-introduced products generally have higher average selling
prices and gross margins, both of which typically decline over product life
cycles due to competitive pressures and volume pricing agreements. Our gross
margin and operating results in the future may continue to fluctuate as a result
of these and other factors.

        The sales cycle for the test and evaluation of our products can range
from three to six months or more, with an additional three to six months or more
before a customer commences volume production of equipment incorporating our
products. Due to these lengthy sales cycles, we may experience a significant
delay between increasing expenses for research and development and selling,
general and administrative efforts, and the generation of corresponding revenue,
if any. Furthermore, during 1999 and thereafter, we intend to continue to
increase our investment in research and development, selling, general and
administrative functions and inventory as we expand our operations. We
anticipate that the rate of new orders may vary significantly from month to
month. Consequently, if anticipated sales and shipments in any quarter do not
occur when expected, expenses and inventory levels could be disproportionately
high, and our operating results for that quarter and, potentially future
quarters, would be materially and adversely affected.

RESULTS OF OPERATIONS

        The following table sets forth certain statement of operations data
expressed as a percentage of revenue for the periods indicated:

YEARS ENDED DECEMBER 31, 1998 AND 1997

        Effects of Pooling-of-Interests Transactions. On May 31, 1999 we
completed the acquisitions of Maverick Networks, Epigram, Inc. and Armedia, Inc.
On August 31, 1999 we completed the acquisitions of HotHaus Technologies Inc.
and AltoCom, Inc. Each of the acquisitions was accounted for as a pooling of
interests. Accordingly, our historical consolidated financial statements and the
discussion and analysis of financial condition and results of operations for
prior periods have been restated to include the pooled operations of these five
companies as if they had combined with our company at the beginning of the first
period presented.

        Revenue. Revenue consists of product revenue generated principally by
sales of our semiconductor products, sales of software and software support and
development revenue generated under development contracts with our customers.
Revenue for 1998 was $216.5 million, an increase of $174.1 million or 411.2% as
compared with revenue of $42.3 million in 1997. The growth in revenue was
derived mainly from increases in volume shipments of our semiconductor products
for the high-speed networking market, digital cable set-top boxes and cable
modems.

        Gross Profit. Gross profit represents revenue less the cost of revenue.
Cost of revenue includes the cost of purchasing the finished silicon wafers
processed by independent foundries, and costs associated with assembly, test and
quality assurance for those products, as well as costs of personnel and
equipment associated with manufacturing support and contracted development work.
Gross profit for 1998 was $125.1 million or 57.8% of revenue, an increase of
$98.3 million or 367.0% from gross profit of $26.8 million or 63.2% of revenue
in 1997. The increase in gross profit was mainly attributable to the significant
increase in the volume of product shipments. The decrease in gross profit as a
percentage of revenue was largely driven by volume pricing agreements on
products for the high-speed networking market. We expect that gross profit as a
percentage of revenue may continue to decline in future periods as
volume-pricing agreements and competitive pricing strategies continue to take
effect. In addition, our gross margin may be affected by the future introduction
of certain lower margin products.

        Research and Development Expense. Research and development expense
consists primarily of salaries and related costs of employees engaged in
research, design and development activities, costs related to engineering design
tools, and subcontracting costs. Research and development expense for 1998 was
$51.1 million or 23.6% of revenue, an increase of $29.5 million or 137.1% as
compared with research and development expense of $21.5 million or 50.9% of
revenue in 1997. The increase in absolute dollars was primarily due to the
addition of personnel and the investment in design tools for the development of
new products and the enhancement of existing products. The decline in research
and development expense as a percentage of revenue reflected a significant
increase in revenue during 1998. We expect that research and development expense
in absolute dollars will continue to increase for the foreseeable future.

        Selling, General and Administrative Expense. Selling, general and
administrative expense consists primarily of personnel-related expenses,
professional fees, trade show expenses and facilities expenses. Selling, general
and administrative expense for 1998 was $32.9 million or 15.2% of revenue, an
increase of $21.5 million or 188.7% as compared with selling, general and
administrative expense of $11.4 million or 26.9% of revenue in 1997. The
increase in absolute dollars reflected higher personnel related costs resulting
from the hiring of sales and marketing personnel, senior management and
administrative personnel, and increased occupancy, legal and other professional
fees, including increased expenses for litigation. The decline in selling,
general and administrative expense as a percentage of revenue reflected a
significant increase in revenue during 1998. We expect that selling, general and
administrative expense in absolute dollars will continue to increase for the
foreseeable future to support the planned continued expansion of our operations
and periodic changes in our infrastructure to support increased headcount,
acquisition and integration activities, and international operations.

        Deferred Compensation. In 1998, we recorded approximately $7.6 million
of net deferred compensation in connection with the grant of certain employee
stock options to purchase shares of our Class B common stock (in addition to
approximately $1.2 million of deferred compensation recorded in 1997). The
deferred compensation represents the difference between the deemed value of the
Class B common stock for accounting purposes and the option exercise price of
such options at the date of grant. We have presented this amount as a reduction
of


                                       6
<PAGE>   7
shareholders' equity and are amortizing this amount ratably over the vesting
period of the applicable options. We amortized an aggregate of $1.8 million of
deferred compensation in 1998.

        Interest and Other Income, Net. Interest and other income, net reflects
interest earned on average cash and cash equivalents and investment balances,
less interest on our long-term debt and capital lease obligations. Interest and
other income, net for 1998 was $4.2 million as compared with $91,000 in 1997.
This increase was principally due to increased cash balances available to invest
resulting from the consummation of our initial public offering and sale of
shares to Cisco Systems, Inc. in April 1998, and a follow-on offering in October
1998.

        Provision (Benefit) for Income Taxes. For financial statement purposes
we accrue a provision (benefit) for federal and state income tax at the
applicable statutory rates. Our effective tax rate was 46% in 1998 and we had an
effective tax benefit of 3% in 1997. The federal statutory tax rates were 35% in
1998 and 34% in 1997. Our effective tax rate was negatively impacted in both
periods by our inability to recognize the tax benefit of Epigram, Armedia and
HotHaus net operating losses incurred during both periods. We utilize the
liability method of accounting for income taxes as set forth in Statement of
Financial Accounting Standards No. 109, Accounting for Income Taxes. See Note 4
of Notes to Consolidated Financial Statements.

YEARS ENDED DECEMBER 31, 1997 AND 1996

        Revenue. Revenue for 1997 was $42.3 million, an increase of $18.5
million or 77.4% as compared with revenue of $23.9 million in 1996. This
increase was primarily due to our introduction of new products and also due to a
higher volume of shipments of existing products to manufacturers of cable
set-top boxes and networking customers selling Fast Ethernet hubs and switches.

        Gross Profit. Gross profit for 1997 was $26.8 million or 63.2% of
revenue, an increase of $11.1 million or 70.6% as compared with gross profit of
$15.7 million or 65.8% of revenue in 1996. The increase in absolute dollars was
largely due to higher revenue. Gross margin declined in 1997 from 1996 primarily
due to volume pricing concessions made in 1997 for cable set-top box products.

        Research and Development Expense. Research and development expense for
1997 was $21.5 million or 50.9% of revenue, an increase of $14.0 million or
185.7% as compared with research and development expense of $7.5 million or
31.6% of revenue in 1996. The increase in research and development expense was
primarily due to the addition of personnel for the development of new products
and the enhancement of existing products, as well as payments to outside
consultants where specific resources were needed in the development process.

        Selling, General and Administrative Expense. Selling, general and
administrative expense for 1997 was $11.4 million or 26.9% of revenue, an
increase of $7.0 million or 161.5% as compared with $4.4 million or 18.3% of
revenue in 1996. The increase in absolute dollars principally reflected higher
personnel related costs resulting from a net increase in sales and marketing
personnel to address each of our target markets. This increase was also due to
the hiring of senior level management and administrative personnel and increased
occupancy, legal and other professional fees. As our infrastructure expanded in
1997, selling, general and administrative expense as a percentage of revenue
increased at a more rapid rate than revenue.

        Deferred Compensation. We recorded deferred compensation of
approximately $1.2 million during 1997 in connection with certain stock options
we granted. The deferred compensation represents the difference between the
deemed value of the Class B common stock for accounting purposes and the option
exercise price of such options at the date of grant. We have presented this
amount as a reduction of shareholders' equity and are amortizing this amount
ratably over the vesting period of the applicable options. In 1997, we amortized
$66,000 of deferred compensation on a pre-tax basis.

        Interest and Other Income, Net. Interest and other income, net reflects
interest earned on average cash and cash equivalents and investment balances,
less interest on our long-term debt and capital lease obligations. Interest and
other income, net for 1997 was $91,000, compared to $165,000 in 1996. The
decrease was primarily due to interest expense incurred on higher average debt
balances, partially offset by interest earned on higher levels of short-term
investments and cash balances.


                                       7
<PAGE>   8

        Provision (Benefit) for Income Taxes. We accrue a provision (benefit)
for federal and state income tax at the applicable statutory rates. We had an
effective tax benefit of 3% in 1997 and an effective tax rate of 38% for 1996.
The federal statutory tax rate was 34% in both 1997 and 1996. Our effective tax
rate was negatively impacted in 1997 by our inability to recognize the tax
benefit of Epigram, Armedia and HotHaus net operating losses incurred during the
period. The difference between our 1996 effective tax rate and the federal
statutory tax rate was primarily related to state income taxes and research and
development tax credits. See Note 4 of Notes to Consolidated Financial
Statements.

LIQUIDITY AND CAPITAL RESOURCES

        Since our inception, we have financed our operations through a
combination of sales of equity securities and cash generated by operations. At
December 31, 1998, we had $131.7 million in working capital, $106.9 million in
cash, cash equivalents and short-term investments, and $42.8 million in
long-term investments.

        Operating activities used cash of $4.0 million in 1998. This was
primarily the result of increases in accounts receivable, inventory, deferred
tax assets and prepaids and other assets, partially offset by net income, the
non-cash impact of depreciation and amortization and a growth in accounts
payable. Operating activities used $6.7 million in cash in 1997 and generated
cash in the amount of $2.5 million in 1996.

        Cash used in operating activities in 1997 was primarily attributable to
a net loss, growth in accounts receivable and inventory, and a decrease in
income taxes payable, which more than offset growth in accounts payable and the
non-cash impact of depreciation and amortization. Cash provided by operating
activities in 1996 was primarily attributable to net income and growth in
accounts payable and income taxes payable, partially offset by growth in
accounts receivable.

        Investing activities used cash in the amount of $77.2 million in 1998
for the net purchase of held-to-maturity investments and $29.1 million for the
purchase of capital equipment to support our expanding operations. Investing
activities used cash of $8.1 million in 1997 and $3.9 million in 1996, primarily
for the purchase of capital equipment.

        Cash provided by financing activities was $149.7 million in 1998, which
was primarily the result of the following:

        o $79.2 million in aggregate net proceeds from our initial public
          offering and sale of Class A common stock to Cisco Systems in April
          1998;

        o $30.5 million in net proceeds from our follow-on offering in October
          1998;

        o $25.2 million in tax benefits related to stock option exercises; and

        o $14.7 million in net proceeds from other issuances of common stock.

        Cash provided by financing activities was $38.1 million in 1997 and $8.4
million in 1996, primarily from the sale of convertible preferred stock and
common stock and, in 1997, from the establishment of a revolving credit facility
and term loan.

        We completed our initial public offering of Class A common stock in
April 1998. Of the 8,050,000 shares of Class A common stock offered, we sold
6,240,000 shares and selling shareholders sold 1,810,000 shares, at a price of
$12.00 per share. In addition, we sold 1,000,000 shares to Cisco Systems in a
concurrent, non-underwritten registered offering at a price of $11.16 per share.
We received net aggregate proceeds from the initial public offering and the sale
of shares to Cisco Systems of approximately $79.2 million in cash, net of
underwriting discounts and commissions and offering costs. In April 1998, we
used approximately $2.3 million of the net proceeds to retire all outstanding
indebtedness under a term loan.

        In October 1998, we completed a follow-on public offering. Of the
6,900,000 shares of Class A common stock offered, we sold 940,000 shares and
selling shareholders sold 5,960,000 shares, at a price of $34.50 per share. We


                                       8
<PAGE>   9

received net aggregate proceeds of approximately $30.5 million after deducting
underwriting discounts and commissions and offering costs.

        We believe that the net proceeds we received from our follow-on
offering, together with the net proceeds we received from our initial public
offering and sale of shares to Cisco Systems and the cash that we generate from
our operations, will be sufficient to meet our capital needs for at least the
next twelve months. However, it is possible that we may need to raise additional
funds to fund our activities beyond the next year. We could raise such funds by
selling more stock to the public or to selected investors, or by borrowing
money. In addition, even though we may not need additional funds, we may still
elect to sell additional equity securities or obtain credit facilities for other
reasons. We may not be able to obtain additional funds on terms that would be
favorable to our shareholders and us, or at all. If we raise additional funds by
issuing additional equity or convertible debt securities, the ownership
percentages of existing shareholders would be reduced. In addition, the equity
or debt securities that we issue may have rights, preferences or privileges
senior to those of the holders of our common stock.

        We had commitments totaling approximately $4.3 million as of December
31, 1998 for the purchase of workstation hardware and software, and for
information systems infrastructure. During 1998, we spent $30.1 million on
capital equipment to support our expanding operations. We expect that we will
spend more than this amount during 1999 to purchase additional workstation
hardware and software, test equipment, design tools, information systems and
leasehold improvements as our operations continue to expand and as we integrate
and upgrade the capital equipment and facilities of acquired companies. We may
finance these purchases from the proceeds of the initial public offering and
sale of shares to Cisco Systems, the proceeds of the follow-on offering, cash
generated from our operations, or a combination thereof. See Note 6 of Notes to
Consolidated Financial Statements.

        Although we believe we have sufficient capital to fund our activities
for at least the next twelve months, our future capital requirements may vary
materially from those now planned. The amount of capital that we will need in
the future will depend on many factors, including:

        o the market acceptance of our products;

        o the levels of promotion and advertising that will be required to
          launch our new products and achieve and maintain a competitive
          position in the marketplace;

        o volume price discounts;

        o our business, product, capital expenditure and research and
          development plans and technology roadmap;

        o the levels of inventory and accounts receivable that we maintain;

        o capital improvements to new and existing facilities;

        o technological advances;

        o our competitors' response to our products; and

        o our relationships with our suppliers and customers.

        In addition, we may require additional capital to accommodate planned
growth, hiring, infrastructure and facility needs or to consummate acquisitions
of other businesses, products or technologies.

YEAR 2000 COMPLIANCE

        We are aware of the widely publicized problems associated with computer
systems as they relate to the Year 2000. Many existing computer hardware systems
and software applications, and embedded computer chips, software and firmware in
control devices use only two digits to identify a year in the date field,
without considering the impact of the upcoming change in the century. Others do
not correctly process "leap year" dates. As a result, such


                                       9
<PAGE>   10

system applications and devices could fail or create erroneous results unless
corrected so that they can correctly process data related to the Year 2000 and
beyond. These problems are expected to increase in frequency and severity as the
Year 2000 approaches.

        We have completed our business risk assessment of the impact that the
Year 2000 problem may have on our operations. We may need to revise this
assessment as new information is made available to us. To date, we have
identified the following four key areas of our business that may be affected:

        Products. We have evaluated each of our current products and believe
that they do not contain date sensitive functionality. We cannot determine
whether all of our customers' products into which our products are incorporated
will be Year 2000 compliant because we have little or no control over the
design, production and testing of our customers' products.

        Internal Infrastructure. The Year 2000 problem could affect the systems,
transaction processing computer applications and devices used by us to operate
and monitor all major aspects of our business, including financial systems (such
as general ledger, accounts payable and payroll), security systems, customer
services, infrastructure, materials requirement planning, master production
scheduling, networks and telecommunications systems and other systems with
embedded computer chips. We believe that we have identified substantially all of
the major systems, software applications and related equipment used in
connection with our internal operations that must be modified or upgraded in
order to minimize the possibility of a material disruption to our business. To
date, we have upgraded or replaced affected critical systems and completed
testing of our Enterprise Resource Planning transactional application and
believe it is Year 2000 ready. Because most of the software applications used by
us are recent versions of vendor supported, commercially available products, we
have not incurred, and do not expect in the future to incur, significant costs
to upgrade these applications as Year 2000 compliant versions are released by
the respective vendors. We will continue to seek certifications that products
installed are Year 2000 ready through the end of 1999.

        Third-Party Suppliers. We rely, directly and indirectly, on external
systems utilized by our third-party suppliers for the management and control of
fabrication and the assembly and testing of substantially all of our products.
We have completed surveys and on-site visits of the two independent foundries,
Taiwan Semiconductor Manufacturing Corporation and Chartered Semiconductor
Manufacturing, that fabricate substantially all of our semiconductor devices in
current production. In addition, we have completed surveys and on-site visits of
the two subcontractors, ASAT Ltd. and ST Assembly Test Services, that assemble
and test substantially all of our current products to identify and, to the
extent possible, resolve issues involving the Year 2000 problem. The key
suppliers mentioned above reported completion of their Year 2000 readiness.
While we continue to monitor their readiness status and expect to resolve any
significant Year 2000 problems, it is possible that these suppliers or new
suppliers will not be able to resolve all or any Year 2000 problems with their
systems in a timely manner. Any failure of these third parties to resolve their
Year 2000 problems in a timely manner could materially disrupt our business. Any
such disruption could negatively impact our sales, harm our relationships with
our customers, and materially and adversely affect our business, financial
condition and results of operations.

        Facility and Laboratory Related Systems. Systems such as heating,
sprinklers, elevators, test equipment and security at our facilities and labs
may also be affected by the Year 2000 problem. We have completed assessing the
business risks of and costs of remediating the Year 2000 problem on our facility
and lab related systems. We estimate that the total cost of completing any
required modifications, upgrades or replacements of these systems will not have
a material adverse effect on our business or results of operations.

        We presently estimate that the total cost of addressing our Year 2000
issues will be approximately $300,000. To date, we have incurred approximately
$80,000 in expenditures for testing of systems. This estimate was derived using
numerous assumptions, including but not limited to the assumptions that we have
already identified our most significant Year 2000 issues and that the plans of
our third party suppliers will be fulfilled in a timely manner without cost to
us. However, these assumptions may not be accurate, and actual results could
differ materially and adversely from those anticipated after completion of
remediation, testing and contingency planning phases.

        We have developed contingency plans to address those Year 2000 issues
that may pose a significant risk to our on-going operations. These plans include
buffer inventories for certain products, implementation of manual


                                       10
<PAGE>   11

procedures to compensate for system deficiencies, and contract IS resources to
immediately address issues should they arise. However, any contingency plans we
implement may not succeed or may not be adequate to meet our needs without
materially impacting our operations. In addition, the delays and inefficiencies
inherent in conducting operations in an alternative manner could materially and
adversely affect our results of operations. More specifically, if our third
party suppliers were to lose power, or the ability to ship product as a result
of Year 2000 related issues, we would be exposed to missing customer shipments
and potentially losing revenues and profits.

RISK FACTORS

        BEFORE DECIDING TO INVEST IN OUR COMPANY OR TO MAINTAIN OR INCREASE YOUR
INVESTMENT, YOU SHOULD CAREFULLY CONSIDER THE RISKS DESCRIBED BELOW, IN ADDITION
TO THE OTHER INFORMATION IN THIS REPORT AND OUR OTHER FILINGS WITH THE SEC,
INCLUDING OUR ANNUAL REPORT ON FORM 10-K AND SUBSEQUENT REPORTS ON FORMS 10-Q
AND 8-K. 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 AFFECT OUR BUSINESS OPERATIONS. IF
ANY OF THESE RISKS ACTUALLY OCCUR, THAT COULD SERIOUSLY HARM OUR BUSINESS,
FINANCIAL CONDITION OR RESULTS OF OPERATIONS. IN THAT EVENT, THE MARKET PRICE
FOR OUR CLASS A COMMON STOCK COULD DECLINE AND YOU MAY LOSE ALL OR PART OF YOUR
INVESTMENT.

OUR QUARTERLY OPERATING RESULTS MAY FLUCTUATE SIGNIFICANTLY. AS A RESULT, WE MAY
FAIL TO MEET OR EXCEED THE EXPECTATIONS OF SECURITIES ANALYSTS AND INVESTORS,
WHICH COULD CAUSE OUR STOCK PRICE TO DECLINE.

        Our quarterly revenues and operating results have fluctuated
significantly in the past and may continue to vary from quarter to quarter due
to a number of factors, many of which are not within our control. If our
operating results do not meet the expectations of securities analysts or
investors, our stock price may decline. Fluctuations in our operating results
may be due to a number of factors, including the following:

        o the volume of our product sales and pricing concessions on volume
          sales;

        o the timing, rescheduling or cancellation of significant customer
          orders;

        o the gain or loss of a key customer;

        o the qualification, availability and pricing of competing products and
          technologies and the resulting effect on sales and pricing of our
          products;

        o wafer pricing and the availability of foundry and assembly capacity
          and raw materials;

        o our ability to specify, develop, complete, introduce, market and
          transition to volume production new products and technologies in a
          timely manner;

        o the timing of customer qualification and industry interoperability
          certification of new products and the risks of non-qualification or
          non-certification;

        o the rate at which our present and future customers and end users adopt
          Broadcom's technologies in our target markets;

        o the rate of adoption and acceptance of new industry standards in our
          target markets;

        o intellectual property disputes and customer indemnification claims;

        o the risks inherent in our acquisitions of technologies and businesses,
          including the timing and successful completion of technology and
          product development through volume production, integration issues,
          costs and unanticipated expenditures, changing relationships with
          customers, suppliers and strategic partners, potential contractual,
          intellectual property or employment issues, accounting charges, and
          the risks that the acquisition cannot be completed successfully or
          that anticipated benefits are not realized;

        o the effectiveness of our product cost reduction efforts;

        o fluctuations in our manufacturing yields and other problems or delays
          in the fabrication, assembly, testing or delivery of our products;

                                       11
<PAGE>   12

        o the effects of new and emerging technologies;

        o risks and uncertainties associated with our international operations;

        o our ability to retain and hire key executives, technical personnel and
          other employees in the numbers, with the capabilities and at the
          compensation levels that we need to implement our business and product
          plans;

        o problems or delays that we may face in shifting our products to
          smaller geometry process technologies and in achieving higher levels
          of design integration;

        o changes in our product or customer mix;

        o the quality of our products and any remediation costs;

        o the effects of natural disasters and other events beyond our control;

        o the level of orders received that we can ship in a fiscal quarter;

        o economic and market conditions in the semiconductor industry and the
          broadband communications markets;

        o potential business disruptions, claims, expenses and other
          difficulties resulting from "Year 2000" problems in computer-based
          systems used by us, our suppliers or our customers; and

        o general economic and market conditions.

        We intend to continue to increase our operating expenses in 1999 and
2000. A large portion of our operating expenses, including rent, salaries and
capital lease expenditures, is fixed and difficult to reduce or change.
Accordingly, if our total revenue does not meet our expectations, we probably
would not be able to adjust our expenses quickly enough to compensate for the
shortfall in revenue. In that event, our business, financial condition and
results of operations would be materially and adversely affected.

        Due to all of the foregoing factors, and the other risks discussed in
this report, you should not rely on quarter-to-quarter comparisons of our
operating results as an indication of future performance.

BECAUSE WE DEPEND ON A FEW SIGNIFICANT CUSTOMERS FOR A SUBSTANTIAL PORTION OF
OUR REVENUES, THE LOSS OF A KEY CUSTOMER COULD SERIOUSLY HARM OUR BUSINESS. IN
ADDITION, IF WE ARE UNABLE TO CONTINUE TO SELL EXISTING AND NEW PRODUCTS TO OUR
KEY CUSTOMERS IN SIGNIFICANT QUANTITIES OR TO ATTRACT NEW SIGNIFICANT CUSTOMERS,
OUR FUTURE OPERATING RESULTS COULD BE ADVERSELY AFFECTED.

        We have derived a substantial portion of our revenues in the past from
sales to a relatively small number of customers. As a result, the loss of any
significant customer could materially and adversely affect our financial
condition and results of operations. Sales to General Instrument and 3Com,
including sales to their respective manufacturing subcontractors, accounted for
approximately 35.5% and 26.8%, respectively, of our revenue in the year ended
December 31, 1998. Sales to our five largest customers, including sales to their
respective manufacturing subcontractors, represented approximately 74.2% of our
revenue in 1998, 56.2% of our revenue in 1997 and 60.6% of our revenue in 1996.
We expect that our key customers will continue to account for a substantial
portion of our revenues for 1999 and in the future. Accordingly, our future
operating results will continue to depend on the success of our largest
customers and on our ability to sell existing and new products to these
customers in significant quantities.

    We may not be able to maintain or increase sales to certain of our key
customers for a variety of reasons, including the following:

        o Most of our customers can stop incorporating our products into their
          own products with limited notice to us and suffer little or no
          penalty.

        o Our agreements with our customers typically do not require them to
          purchase a minimum amount of our products.

        o Many of our customers have pre-existing relationships with our current
          or potential competitors that may affect their decision to purchase
          our products.

                                       12
<PAGE>   13

        o Our customers face intense competition from other manufacturers that
          do not use our products.

        o Some of our customers offer or may offer products that compete with
          our products.

        o Our longstanding relationships with some of our larger customers may
          also deter other potential customers who compete with these customers
          from buying our products.

        In addition, in order to attract new customers or retain existing
customers, we may offer certain customers favorable prices on our products. If
these prices are lower than the prices paid by our existing customers, we would
have to offer the same lower prices to certain of our customers who have
contractual "most favored nation" pricing arrangements. In that event, our
average selling prices and gross margins would decline. The loss of a key
customer, a reduction in our sales to any key customer or our inability to
attract new significant customers could materially and adversely affect our
business, financial condition or results of operations.

WE FACE INTENSE COMPETITION IN THE BROADBAND COMMUNICATIONS MARKETS AND
SEMICONDUCTOR INDUSTRY, WHICH COULD REDUCE OUR MARKET SHARE IN EXISTING MARKETS
AND AFFECT OUR ENTRY INTO NEW MARKETS.

        The broadband communications markets and semiconductor industry are
intensely competitive. We expect competition to continue to increase in the
future as industry standards become well known and as other competitors enter
our target markets. We currently compete with a number of major domestic and
international suppliers of integrated circuits in the markets for cable set-top
boxes, cable modems, high-speed office networks, home networking, direct
broadcast satellite and terrestrial digital satellite, and digital subscriber
lines. This competition has resulted and may continue to result in declining
average selling prices for our products. We currently compete in the cable
set-top box market with Conexant, Fujitsu, LSI Logic, Motorola, Philips
Electronics, STMicroelectronics, Texas Instruments and VLSI Technology, a
subsidiary of Philips Electronics, for communication devices, and with ATI
Technologies, C-Cube, LSI Logic, Motorola, STMicroelectronics and Texas
Instruments in the MPEG/graphics segment. We expect that other major
semiconductor manufacturers will enter the market as digital broadcast
television and other digital cable television markets become more established. A
number of companies, including Conexant, Libit Signal Processing, a subsidiary
of Texas Instruments, and others have announced MCNS/DOCSIS compliant products,
which could result in significant competition in the cable modem market. In the
high-speed office networking market, we principally compete with established
suppliers including Galileo, Level One Communications, a subsidiary of Intel
Corporation, Lucent Technologies, National Semiconductor and Texas Instruments.
A number of smaller companies have announced products in our target markets,
such as Altima, Seeq, a subsidiary of LSI Logic, and Allayer. We also compete
for customer specific ASICs against traditional ASIC suppliers such as Lucent,
LSI Logic, NEC and Toshiba. Our principal competitors in the DBS and terrestrial
broadcast market include Conexant, Fujitsu, Hyundai, LG Semiconductors, Libit,
LSI Logic, Lucent, Motorola, Nxtwave Communications, Oren, Philips Electronics,
Sony, STMicroelectronics and VLSI Technology. Our principal competitors in the
xDSL market include Alcatel, Analog Devices, Conexant, Globespan, Lucent,
Motorola, Siemens and Texas Instruments. As the home networking market develops,
we expect to encounter competition from various competitors, including Advanced
Micro Devices, Conexant, Intel, Lucent and Texas Instruments. In all of the
foregoing markets, we also may face competition from newly established
competitors and suppliers of products based on new or emerging technologies. We
also believe we will encounter further consolidation in the markets in which we
compete.

        Many of our competitors operate their own fabrication facilities and
have longer operating histories and presence in key markets, greater name
recognition, larger customer bases and significantly greater financial, sales
and marketing, manufacturing, distribution and technical resources than we do.
As a result, these competitors may be able to adapt more quickly than we can to
new or emerging technologies and changes in customer requirements. They may also
be able to devote greater resources than we can to the promotion and sale of
their products. In addition, current and potential competitors have established
or may establish financial or strategic relationships among themselves or with
existing or potential customers, resellers or other third parties. Accordingly,
it is possible that new competitors or alliances among competitors could emerge
and rapidly acquire significant market share. Existing or new competitors may
also develop technologies in the future that more effectively address the
transmission of digital information through existing analog infrastructures at
lower costs than our technologies. Increased competition has in the past and is
likely to continue to result in price reductions, reduced gross margins and loss
of market share. We cannot assure you that we will be able to continue to
compete successfully or that


                                       13
<PAGE>   14

competitive pressures will not materially and adversely affect our business,
financial condition and results of operations.

OUR ACQUISITION STRATEGY MAY REQUIRE US TO MAKE SIGNIFICANT CAPITAL INFUSIONS,
BE DILUTIVE TO OUR EXISTING SHAREHOLDERS, AND RESULT IN DIFFICULTIES IN
ASSIMILATING AND INTEGRATING THE OPERATIONS, PERSONNEL, TECHNOLOGIES, PRODUCTS
AND INFORMATION SYSTEMS OF ACQUIRED COMPANIES.

        A key element of our business strategy involves expansion through the
acquisition of businesses, products or technologies that would allow us to
complement our existing product offerings, expand our market coverage or enhance
our technological capabilities. Since January 1999, we have acquired Maverick
Networks, Epigram, Inc., Armedia, Inc., HotHaus Technologies Inc. and AltoCom,
Inc. We plan to continue to pursue acquisition opportunities in the future.
Acquisitions may require significant capital infusions, typically entail many
risks and could result in difficulties in assimilating and integrating the
operations, personnel, technologies, products and information systems of the
acquired company. We may also encounter delays in the timing and successful
completion of the acquired company's technology and product development to
production readiness, unanticipated expenditures, changing relationships with
customers, suppliers and strategic partners, or contractual, intellectual
property or employment issues. In addition, the key personnel of the acquired
company may decide not to work for us. The acquisition of another company or its
products and technologies may also require us to enter into a geographic or
business market in which we have little or no prior experience. These challenges
could disrupt our ongoing business, distract our management and employees and
increase our expenses. In addition, acquisitions may materially and adversely
affect our results of operations because they may require large one-time
write-offs, increased debt and contingent liabilities, substantial depreciation
or deferred compensation charges or the amortization of expenses related to
goodwill and other intangible assets. We may seek to account for acquisitions
under the pooling-of-interests accounting method, but that method may not be
available. Any of these events could cause the price of our Class A common stock
to decline. Furthermore, if we issue equity or convertible debt securities to
pay for an acquisition, as in the case of our recent acquisitions, the issuance
may be dilutive to our existing shareholders. In addition, the equity or debt
securities that we may issue could have rights, preferences or privileges senior
to those of the holders of our common stock.

        We cannot assure you that we will be able to consummate any of our
acquisitions or that we will realize the benefits anticipated from these
acquisitions. In the future, we may not be able to find other suitable
acquisition opportunities. Even if we do find suitable acquisition
opportunities, we may not be able to consummate the acquisitions on commercially
acceptable terms. Moreover, due to our limited acquisition experience, it may be
difficult for us to successfully integrate any acquired businesses, products,
technologies or personnel, which could materially and adversely affect our
business, financial condition and results of operations.

WE MUST KEEP PACE WITH RAPID TECHNOLOGICAL CHANGES IN THE SEMICONDUCTOR INDUSTRY
AND BROADBAND COMMUNICATIONS MARKETS IN ORDER TO REMAIN COMPETITIVE.

        Our future success will depend on our ability to anticipate and adapt to
changes in technology and industry standards. We will also need to continue to
develop and introduce new and enhanced products to meet our customers' changing
demands. Substantially all of our current product revenue is derived from sales
of products for the high-speed networking, cable set-top box and cable modem
markets. These markets are characterized by rapidly changing technology,
evolving industry standards, frequent new product introductions and short
product life cycles. In addition, these markets continue to undergo rapid growth
and consolidation. A significant slowdown in any of these markets or other
broadband communications markets could materially and adversely affect our
business, financial condition and results of operations. Our success will also
depend on the ability of our customers to develop new products and enhance
existing products for the broadband communications markets and to successfully
introduce and promote those products. The broadband communications markets may
not continue to develop to the extent or in the timeframes that we anticipate.
If new markets do not develop as we anticipate or if our products do not gain
widespread acceptance in these markets, our business, financial condition and
results of operations could be materially and adversely affected.

IF WE DO NOT ANTICIPATE AND ADAPT TO EVOLVING INDUSTRY STANDARDS IN THE
SEMICONDUCTOR INDUSTRY AND BROADBAND COMMUNICATIONS MARKETS, OUR PRODUCTS COULD
BECOME OBSOLETE AND WE COULD LOSE MARKET SHARE.

                                       14
<PAGE>   15

        Products for broadband communications applications generally are based
on industry standards that are continually evolving. If new industry standards
emerge, our products or our customers' products could become unmarketable or
obsolete. We may also have to incur substantial unanticipated costs to comply
with these new standards. Our past sales and profitability have resulted, to a
large extent, from our ability to anticipate changes in technology and industry
standards and to develop and introduce new and enhanced products. Our ability to
adapt to these changes and to anticipate future standards, and the rate of
adoption and acceptance of those standards, will be a significant factor in
maintaining or improving our competitive position and prospects for growth. We
have in the past invested substantial resources in emerging technologies, such
as 100Base-T4 for high-speed networking, which did not achieve the market
acceptance that we had expected. Our inability to anticipate the evolving
standards in the semiconductor industry and, in particular the broadband
communications markets, or to develop and introduce new products successfully
into these markets could materially and adversely affect our business, financial
condition and results of operations.

IF WE ARE UNABLE TO DEVELOP AND INTRODUCE NEW SILICON SOLUTIONS SUCCESSFULLY AND
IN A COST-EFFECTIVE AND TIMELY MANNER OR TO ACHIEVE MARKET ACCEPTANCE OF OUR NEW
PRODUCTS, OUR OPERATING RESULTS WOULD BE ADVERSELY AFFECTED.

        Our future success will depend on our ability to develop new silicon
solutions for existing and new markets, introduce these products in a
cost-effective and timely manner and convince leading equipment manufacturers to
select these products for design into their own new products. Our quarterly
results in the past have been, and are expected in the future to continue to be,
dependent on the introduction of a relatively small number of new products and
the timely completion and delivery of those products to customers. The
development of new silicon devices is highly complex, and from time to time we
have experienced delays in completing the development and introduction of new
products. Our ability to successfully develop and deliver new products will
depend on various factors, including our ability to:

        o accurately predict market requirements and evolving industry
          standards;

        o accurately define new products;

        o timely complete and introduce new product designs;

        o timely qualify and obtain industry interoperability certification of
          our products and our customers' products into which our products will
          be incorporated;

        o obtain sufficient foundry capacity;

        o achieve high manufacturing yields; and

        o gain market acceptance of our products and our customers' products.

        If we are not able to develop and introduce new products successfully
and in a cost-effective and timely manner, our business, financial condition and
results of operations would be materially and adversely affected.

        Our new products generally are incorporated into our customers' products
at the design stage. We have often incurred significant expenditures on the
development of a new product without any assurance that an equipment
manufacturer will select our product for design into its own product. The value
of our products largely depends on the commercial success of our customers'
products and on the extent to which those products accommodate components
manufactured by our competitors. We cannot assure you that we will continue to
achieve design wins. In addition, the equipment that incorporates our products
may never become commercially successful.

WE DEPEND ON TWO INDEPENDENT FOUNDRIES TO MANUFACTURE SUBSTANTIALLY ALL OF OUR
CURRENT PRODUCTS, AND ANY FAILURE TO OBTAIN SUFFICIENT FOUNDRY CAPACITY COULD
MATERIALLY AND ADVERSELY AFFECT OUR BUSINESS.

        We do not own or operate a fabrication facility. Two outside foundries,
Taiwan Semiconductor Manufacturing Corporation, or TSMC, in Taiwan and Chartered
Semiconductor Manufacturing, or Chartered, in Singapore, currently manufacture
substantially all of our semiconductor devices in current production. In
September 1999, TSMC's principal facility was affected by a significant
earthquake in Taiwan. As a consequence of this earthquake,


                                       15
<PAGE>   16
TSMC suffered power outages and equipment damage that have impaired TSMC's wafer
deliveries and, together with strong demand, could result in wafer shortages and
higher wafer pricing industrywide.

        Because we rely on outside foundries with limited capacity, we face
several significant risks, including:

        o a lack of ensured wafer supply;

        o limited control over delivery schedules, quality assurance and
          control, manufacturing yields and production costs; and

        o the unavailability of or potential delays in obtaining access to key
          process technologies.

        In addition, the manufacture of integrated circuits is a highly complex
and technologically demanding process. Although we work closely with our
foundries to minimize the likelihood of reduced manufacturing yields, our
foundries have from time to time experienced lower than anticipated
manufacturing yields. This often occurs during the production of new products or
the installation and start-up of new process technologies.

        The ability of each foundry to provide us with semiconductor devices is
limited by its available capacity. Although we have entered into contractual
commitments to supply specified levels of products to certain of our customers,
we do not have a long-term volume purchase agreement or a guaranteed level of
production capacity with either TSMC or Chartered. Excess foundry capacity may
not always be available when we need it or at reasonable prices. Availability of
excess foundry capacity has recently been reduced due to strong demand. We place
our orders on the basis of our customers' purchase orders, and TSMC and
Chartered can allocate capacity to the production of other companies' products
and reduce deliveries to us on short notice. It is possible that foundry
customers that are larger and better financed than we are or that have long-term
agreements with TSMC or Chartered, may induce our foundries to reallocate
capacity to them. Such a reallocation could impair our ability to secure the
supply of components that we need. Although we primarily use two independent
foundries, most of our components are not manufactured at both foundries at any
given time and some of our products may be designed to be manufactured at only
one. Accordingly, if one of our foundries is unable to provide us with
components as needed, we could experience significant delays in securing
sufficient supplies of those components. Any of these delays would likely
materially and adversely affect our business, financial condition and results of
operations. In addition, if either TSMC or Chartered experiences financial
difficulties, whether as a result of the recent Asian economic crisis or
otherwise, if either foundry suffers any damage to its facilities or in the
event of any other disruption of foundry capacity, we may not be able to qualify
an alternative foundry in a timely manner. Even our current foundries would need
to have new manufacturing processes qualified if there is a disruption in an
existing process. If we choose to use a new foundry or process, it would
typically take us several months to qualify the new foundry or process before we
can begin shipping products from it. If we cannot accomplish this qualification
in a timely manner, we may still experience a significant interruption in supply
of the affected products. We cannot assure you that any of our existing or new
foundries would be able to produce integrated circuits with acceptable
manufacturing yields. Furthermore, our foundries may not be able to deliver
enough semiconductor devices to us on a timely basis, or at reasonable prices.

        Maverick and Broadcom HomeNetworking, Inc., formerly known as Epigram,
Inc., have established relationships with foundries other than TSMC and
Chartered, and we currently expect to use these other foundries to produce the
initial products of Maverick and Broadcom HomeNetworking, subject to
satisfactory qualification. We may utilize such foundries for other products in
the future. In using these new foundries, we will be subject to all of the same
risks described in the foregoing paragraphs with respect to TSMC and Chartered.

WE MAY BE UNABLE TO RETAIN KEY TECHNICAL AND SENIOR MANAGEMENT PERSONNEL AND
ATTRACT ADDITIONAL KEY EMPLOYEES, WHICH COULD SERIOUSLY HARM OUR BUSINESS.

        Our future success depends to a significant extent upon the continued
service of our key technical and senior management personnel, in particular, our
co-founder, President and Chief Executive Officer, Dr. Henry T. Nicholas III,
and our co-founder, Vice President of Research & Development, and Chief
Technical Officer, Dr. Henry Samueli. We do not have employment agreements with
these executives or any other key employees that govern the length of their
service. The loss of the services of Dr. Nicholas or Dr. Samueli, or certain
other key employees,


                                       16
<PAGE>   17

would likely materially and adversely affect our business, financial condition
and results of operations. Our future success also depends on our ability to
continue to attract, retain and motivate qualified personnel, particularly
digital circuit designers, mixed-signal circuit designers and systems
applications engineers. Competition for these employees is intense. We may not
be able to attract as many qualified new personnel as we were able to employ
prior to our initial public offering. Our inability to attract and retain
additional key employees could have an adverse effect on our business, financial
condition and results of operations.

OUR INABILITY TO MANAGE OUR SIGNIFICANT RECENT AND ANTICIPATED FUTURE GROWTH
COULD STRAIN OUR MANAGERIAL, OPERATIONAL AND FINANCIAL RESOURCES, AND COULD
MATERIALLY AND ADVERSELY AFFECT OUR BUSINESS.

        During the past year, we have significantly increased the scope of our
operations and expanded our workforce, growing from 546 employees in September
1998 to 849 employees in September 1999, including contract and temporary
employees. This growth has placed, and our anticipated future growth of
operations is expected to continue to place, a significant strain on our
management personnel, systems and resources. We anticipate that we will need to
implement a variety of new and upgraded operational and financial systems,
procedures and controls, including the ongoing improvement of our accounting and
other internal management systems. We also expect we will need to continue to
expand, train, manage and motivate our workforce. All of these endeavors will
require substantial management effort. In order to support our growth, we
recently relocated our headquarters and Irvine operations into larger
facilities, which allowed us to centralize all of our Irvine employees and
operations on one campus. In the future, we may engage in other relocations of
our employees or operations from time to time. These relocations could result in
temporary disruptions of our operations or a diversion of our management's
attention and resources. If we are unable to effectively manage our expanding
operations, our business, financial condition and results of operations could be
materially and adversely affected.

THE LOSS OF EITHER OF THE TWO THIRD-PARTY SUBCONTRACTORS THAT ASSEMBLE AND TEST
SUBSTANTIALLY ALL OF OUR CURRENT PRODUCTS COULD DISRUPT OUR SHIPMENTS, HARM OUR
CUSTOMER RELATIONSHIPS AND ADVERSELY AFFECT OUR NET SALES.

        Two third-party subcontractors, ASAT Ltd. in Hong Kong and ST Assembly
Test Services, or STATS, in Singapore, assemble and test almost all of our
current products. Because we rely on third-party subcontractors to assemble and
test our products, we cannot directly control our product delivery schedules and
quality assurance and control. This lack of control has in the past, and could
in the future, result in product shortages or quality assurance problems that
could increase our manufacturing, assembly or testing costs. We do not have
long-term agreements with either ASAT or STATS. We typically procure services
from these suppliers on a per order basis. If either ASAT or STATS experiences
capacity constraints or financial difficulties, whether as a result of the
recent Asian economic crisis or otherwise, if either subcontractor suffers any
damage to its facilities or in the event of any other disruption of assembly and
testing capacity, we may not be able to obtain alternative assembly and testing
services in a timely manner. Due to the amount of time that it usually takes us
to qualify assemblers and testers, we could experience significant delays in
product shipments if we are required to find alternative assemblers or testers
for our components. Any problems that we may encounter with the delivery,
quality or cost of our products could materially and adversely affect our
business, financial condition or results of operations.

AS OUR INTERNATIONAL BUSINESS EXPANDS, OUR BUSINESS, FINANCIAL CONDITION AND
OPERATING RESULTS COULD BE ADVERSELY AFFECTED AS A RESULT OF LEGAL, BUSINESS AND
ECONOMIC RISKS SPECIFIC TO INTERNATIONAL OPERATIONS.

        We currently obtain substantially all of our manufacturing, assembly and
testing services from suppliers located outside of the United States. In
addition, approximately 17.2% of our revenue in the year ended December 31, 1998
was derived from sales to independent customers outside the United States. We
also frequently ship products to our domestic customers' international
manufacturing divisions and subcontractors. We recently established an
international distribution center in Singapore and a design center in The
Netherlands. As a result of our acquisition of HotHaus in August 1999, we now
undertake software design, development and marketing activities in Canada.
Furthermore, as a result of our acquisition of Armedia in May 1999, we also
undertake design and development activities in India. In the future, we intend
to continue to expand these international business activities and also to open
other design and operational centers abroad. International operations are
subject to many inherent risks, including:

                                       17
<PAGE>   18

        o political, social and economic instability;

        o trade restrictions;

        o the imposition of governmental controls;

        o exposure to different legal standards, particularly with respect to
          intellectual property;

        o burdens of complying with a variety of foreign laws;

        o import and export license requirements and restrictions of the United
          States and each other country in which we operate;

        o unexpected changes in regulatory requirements;

        o foreign technical standards;

        o changes in tariffs;

        o difficulties in staffing and managing international operations;

        o fluctuations in currency exchange rates;

        o difficulties in collecting receivables from foreign entities; and

        o potentially adverse tax consequences.

        BECAUSE WE RELY ON ASIAN FOUNDRIES AND ASSEMBLERS AND HAVE EXPANDED OUR
        INTERNATIONAL OPERATIONS IN ASIA, OUR BUSINESS MAY BE MATERIALLY AND
        ADVERSELY AFFECTED BY THE RECENT ASIAN ECONOMIC CRISIS.

        Certain Asian countries have recently experienced significant economic
difficulties. These difficulties include currency devaluation and instability,
business failures and a generally depressed business climate, particularly in
the semiconductor industry. Because we rely on Asian foundries and assemblers
and have expanded our international operations in that region, the Asian
economic crisis may materially and adversely affect our business, financial
condition and results of operations.

        VARIOUS EXPORT LICENSING REQUIREMENTS, THE SEASONALITY OF INTERNATIONAL
        SALES OR AN INCREASE IN THE VALUE OF THE U.S. DOLLAR RELATIVE TO FOREIGN
        CURRENCIES COULD MATERIALLY AND ADVERSELY AFFECT OUR BUSINESS OR REQUIRE
        US TO MODIFY OUR CURRENT BUSINESS PRACTICES SIGNIFICANTLY.

        Various government export regulations apply to the encryption or other
features contained in some of our products. We have applied for and received
several export licenses under these regulations, but we cannot assure you that
we will obtain any licenses for which we have currently applied or any licenses
that we may apply for in the future. If we do not receive the required licenses,
we may be unable to manufacture the affected products at our foreign foundries
or to ship these products to certain customers located outside the United
States. Moreover, the seasonality of international sales and economic conditions
in our primary overseas markets may negatively impact the demand for our
products abroad. All of our international sales to date have been denominated in
U.S. dollars. Accordingly, an increase in the value of the U.S. dollar relative
to foreign currencies could make our products less competitive in international
markets. Any one or more of the foregoing factors could materially and adversely
affect our business, financial condition or results of operations or require us
to modify our current business practices significantly. We anticipate that these
factors will impact our business to a greater degree as we further expand our
international business activities.

OUR FUTURE SUCCESS DEPENDS IN SIGNIFICANT PART ON STRATEGIC RELATIONSHIPS WITH
CERTAIN OF OUR CUSTOMERS. IF WE CANNOT MAINTAIN THESE RELATIONSHIPS OR IF THESE
CUSTOMERS DEVELOP THEIR OWN SOLUTIONS OR ADOPT A COMPETITOR'S SOLUTIONS INSTEAD
OF BUYING OUR PRODUCTS, OUR OPERATING RESULTS WOULD BE ADVERSELY AFFECTED.

        In the past, we have relied on our strategic relationships with certain
customers who are technology leaders in our target markets. We intend to pursue
and continue to form these strategic relationships in the future. These
relationships often require us to develop new products that typically involve
significant technological challenges. Our partners frequently place considerable
pressure on us to meet their tight development schedules. Accordingly,


                                       18
<PAGE>   19

we may have to devote a substantial amount of our limited resources to our
strategic relationships, which could detract from or delay our completion of
other important development projects. Delays in development could impair our
relationships with our strategic partners and negatively impact sales of the
products under development. Moreover, it is possible that our customers may
develop their own solutions or adopt a competitor's solution for products that
they currently buy from us. If that happens, our business, financial condition
and results of operations would be materially and adversely affected.

WE MAY EXPERIENCE DIFFICULTIES IN TRANSITIONING TO SMALLER GEOMETRY PROCESS
TECHNOLOGIES OR IN ACHIEVING HIGHER LEVELS OF DESIGN INTEGRATION THAT MAY RESULT
IN REDUCED MANUFACTURING YIELDS, DELAYS IN PRODUCT DELIVERIES AND INCREASED
EXPENSES.

        In order to remain competitive, we believe that we will have to
transition our products to increasingly smaller geometries. This transition will
require us to redesign certain of our products and modify the manufacturing
process for our products. We continually evaluate the benefits, on a
product-by-product basis, of migrating to smaller geometry process technologies
in order to reduce our costs, and we have begun shifting some of our products
from .50 micron to .35 micron and smaller geometry processes. In the past, we
have experienced some difficulties in shifting to smaller geometry process
technologies or new manufacturing processes. These difficulties resulted in
reduced manufacturing yields, delays in product deliveries and increased
expenses. We may face similar difficulties, delays and expenses as we continue
to transition our products to smaller geometry processes. We are dependent on
our relationships with our foundries to transition to smaller geometry processes
successfully. We cannot assure you that our foundries will be able to
effectively manage the transition or that we will be able to maintain our
relationships with our foundries. If our foundries or we experience significant
delays in this transition or fail to efficiently implement this transition, our
business, financial condition and results of operations could be materially and
adversely affected. As smaller geometry processes become more prevalent, we
expect to integrate greater levels of functionality, as well as customer and
third party intellectual property, into our products. However, we may not be
able to achieve higher levels of design integration or deliver new integrated
products on a timely basis, or at all.

WE MAY NOT BE ABLE TO ADEQUATELY PROTECT OR ENFORCE OUR INTELLECTUAL PROPERTY
RIGHTS, WHICH COULD HARM OUR COMPETITIVE POSITION.

        Our success and future revenue growth will depend, in part, on our
ability to protect our intellectual property. We primarily rely on patent,
copyright, trademark and trade secret laws, as well as nondisclosure agreements
and other methods, to protect our proprietary technologies and processes.
Despite our efforts to protect our proprietary technologies and processes, it is
possible that certain of our competitors or other parties may obtain, use or
disclose our technologies and processes. We currently hold five issued United
States patents and have filed over 180 United States patent applications. We
cannot assure you that any additional patents will be issued. Even if a new
patent is issued, the claims allowed may not be sufficiently broad to protect
our technology. In addition, any of our existing or future patents may be
challenged, invalidated or circumvented. Moreover, any rights granted under
these patents may not provide us with meaningful protection. If our patents do
not adequately protect our technology, then our competitors may be able to offer
products similar to ours. Our competitors may also be able to develop similar
technology independently or design around our patents. Moreover, because we have
participated in developing various industry standards, we may be required to
license some of our technology and patents to others, including competitors, who
develop products based on the adopted standards.

        We generally enter into confidentiality agreements with our employees
and strategic partners. We also try to control access to and distribution of our
technologies, documentation and other proprietary information. Despite these
efforts, parties may attempt to copy, disclose, obtain or use our products,
services or technology without our authorization. As a result, our technologies
and processes may be misappropriated, particularly in foreign countries where
laws may not protect our proprietary rights as fully as in the United States.

        In addition, some of our customers have entered into agreements with us
that grant them the right to use our proprietary technology if we ever fail to
fulfill our obligations under those agreements, including product supply
obligations, and do not correct this failure within a specified time period.
Moreover, we often incorporate the intellectual property of our strategic
customers into our own designs, and have certain obligations not to use or
disclose their intellectual property without their authorization. We cannot
assure you that our efforts to prevent the


                                       19
<PAGE>   20

misappropriation or infringement of our intellectual property or the
intellectual property of our customers will succeed. In the future, we may have
to engage in litigation to enforce our intellectual property rights, protect our
trade secrets or determine the validity and scope of the proprietary rights of
others, including our customers. This litigation may be very expensive, divert
management's attention and materially and adversely affect our business,
financial condition and results of operations.

        INFRINGEMENT OR OTHER CLAIMS AGAINST US COULD ADVERSELY AFFECT OUR
        ABILITY TO MARKET OUR PRODUCTS, REQUIRE US TO REDESIGN OUR PRODUCTS OR
        SEEK LICENSES FROM THIRD PARTIES AND SERIOUSLY HARM OUR OPERATING
        RESULTS.

        Companies in the semiconductor industry often aggressively protect and
pursue their intellectual property rights. From time to time, we have received,
and may continue to receive in the future, notices that claim we have infringed
upon, misappropriated or misused other parties' proprietary rights. We recently
settled litigation with Stanford Telecommunications, Inc. that related to the
alleged infringement of one of Stanford's patents by several of our modem
products. We recently prevailed in litigation with Sarnoff Corporation and
NxtWave Communications, Inc., formerly Sarnoff Digital Communications, Inc., who
alleged that we misappropriated and misused certain of their trade secrets. Our
subsidiary, AltoCom, is the defendant in patent litigation brought by Motorola,
Inc. It is possible that we will not prevail in these matters. In addition, we
may be sued in the future by other parties who claim that we have infringed
their patents or misappropriated or misused their trade secrets, or who may seek
to invalidate one of our patents. Any of these claims may materially and
adversely affect our business, financial condition and results of operations.
For example, in a patent or trade secret action, a court could issue an
injunction against us that would require us to withdraw or recall certain
products from the market or redesign certain products offered for sale or under
development. In addition, we may be liable for damages for past infringement and
royalties for future use of the technology. We may also have to indemnify
certain customers and strategic partners under our agreements with these parties
if a third party alleges or if a court finds that we have infringed upon,
misappropriated or misused these party's proprietary rights. Even if claims
against us are not valid or successfully asserted, these claims could result in
significant costs and a diversion of management and personnel resources to
defend. In that event, our business, financial condition and results of
operations would likely be materially and adversely affected. If any claims or
actions are asserted against us, we may seek to obtain a license under a third
party's intellectual property rights. However, we may not be able to obtain a
license on commercially reasonable terms, if at all.

OUR PRODUCTS TYPICALLY HAVE LENGTHY SALES CYCLES THAT INCREASE OUR RISK THAT A
CUSTOMER WILL DECIDE TO CANCEL OR CHANGE ITS PRODUCT PLANS, WHICH COULD CAUSE US
TO LOSE ANTICIPATED SALES. IN ADDITION, OUR AVERAGE PRODUCT CYCLES TEND TO BE
SHORT AND, AS A RESULT, WE MAY HOLD EXCESS OR OBSOLETE INVENTORY WHICH COULD
ADVERSELY AFFECT OUR OPERATING RESULTS.

        After we have developed and delivered a product to a customer, our
customer will often test and evaluate our product prior to designing its own
equipment to incorporate our product. Our customer may need three to six months
or longer to test and evaluate our product and an additional three to six months
or more to begin volume production of equipment that incorporates our product.
Due to this lengthy sales cycle, we may experience delays from the time we
increase our operating expenses and our investments in inventory, until the time
that we generate revenues for these products. It is possible that we may never
generate any revenues from these products after incurring these expenditures.
Even if a customer selects our product to incorporate into its equipment, we
have no assurances that this customer will ultimately market and sell their
equipment or that these efforts by our customer will be successful. The delays
inherent in our lengthy sales cycle increase the risk that a customer will
decide to cancel or change its product plans. Such a cancellation or change in
plans by a customer could cause us to lose sales that we had anticipated. In
addition, our business, financial condition and results of operations could be
materially and adversely affected if a significant customer curtails, reduces or
delays orders during our sales cycle or chooses not to release equipment that
contains our products.

        While our sales cycles are typically long, our average product life
cycles tend to be short as a result of the rapidly changing technology
environment in which we operate. As a result, the resources devoted to product
sales and marketing may not generate material revenues for us, and from time to
time, we may need to write off excess and obsolete inventory. If we incur
significant marketing and inventory expenses in the future that we are not able
to recover, and we are not able to compensate for these expenses, our operating
results could be adversely affected. In


                                       20
<PAGE>   21

addition, if we sell our products at reduced prices in anticipation of cost
reductions, and we still have higher cost products in inventory, our operating
results would be harmed.

BECAUSE WE ARE SUBJECT TO ORDER AND SHIPMENT UNCERTAINTIES, ANY SIGNIFICANT
CANCELLATIONS OR DEFERRALS COULD SERIOUSLY HARM OUR OPERATING RESULTS.

        We typically sell products pursuant to purchase orders that customers
can generally cancel or defer on short notice without incurring a significant
penalty. Any significant cancellations or deferrals could materially and
adversely affect our business, financial condition and results of operations. In
addition, cancellations or deferrals could cause us to hold excess inventory,
which could reduce our profit margins and restrict our ability to fund our
operations. We recognize revenue upon shipment of products to a customer. If a
customer refuses to accept shipped products or does not timely pay for these
products, we could incur significant charges against our income. These charges
could materially and adversely affect our operating results.

THE COMPLEXITY OF OUR PRODUCTS COULD RESULT IN UNFORESEEN DELAYS OR EXPENSES AND
IN UNDETECTED DEFECTS OR BUGS, WHICH COULD ADVERSELY AFFECT THE MARKET
ACCEPTANCE OF NEW PRODUCTS AND DAMAGE OUR REPUTATION WITH OUR CURRENT OR
PROSPECTIVE CUSTOMERS.

        Highly complex products such as the products that we offer frequently
contain defects and bugs when they are first introduced or as new versions are
released. We have in the past experienced, and may in the future continue to
experience, these errors, defects and bugs. If any of our products contain
defects or bugs, or have reliability, quality or compatibility problems, our
reputation may be damaged and customers may be reluctant to buy our products,
which could materially and adversely affect our ability to retain existing
customers or attract new customers. In addition, these defects or problems could
interrupt or delay sales to our customers. In order to alleviate these problems,
we may have to invest significant capital and other resources. Although our
suppliers, our customers and we test our products, we cannot assure you that our
new products will not contain defects or bugs. If any of these problems are not
found until after we have commenced commercial production of a new product, we
may be required to incur additional development costs and product repair or
replacement costs. These problems may also result in claims against us by our
customers or others. In addition, these problems may divert our technical and
other resources from other development efforts. Moreover, we would likely lose,
or experience a delay in, market acceptance of the affected product or products
and lose credibility with our current and prospective customers.

OUR OPERATING RESULTS MAY VARY SIGNIFICANTLY DUE TO THE CYCLICALITY OF THE
SEMICONDUCTOR INDUSTRY. ANY SUCH VARIATIONS COULD ADVERSELY AFFECT THE MARKET
PRICE OF OUR COMMON STOCK.

        We operate in the semiconductor industry, which is highly cyclical and
subject to rapid technological change. From time to time, the semiconductor
industry has experienced significant economic downturns, characterized by
diminished product demand, accelerated erosion of prices and excess production
capacity. This industry also periodically experiences increased demand and
production capacity constraints. Accordingly, our quarterly results may vary
significantly as a result of the general conditions in the semiconductor
industry.

OUR CALIFORNIA FACILITIES AND THE FACILITIES OF ONE OF THE TWO INDEPENDENT
FOUNDRIES UPON WHICH WE RELY TO MANUFACTURE SUBSTANTIALLY ALL OF OUR CURRENT
PRODUCTS ARE LOCATED IN REGIONS THAT ARE SUBJECT TO EARTHQUAKES AND OTHER
NATURAL DISASTERS.

        Our California facilities, including our principal executive offices,
are located near major earthquake fault lines. If there is a major earthquake or
any other natural disaster in a region where one of our facilities is located,
our business could be materially and adversely affected. In addition, TSMC, one
of the two outside foundries upon which we rely to manufacture substantially all
of our semiconductor devices, is located in Taiwan, a country that is also
subject to earthquakes. Any earthquake or other natural disaster in Taiwan could
materially disrupt TSMC's production capabilities and could result in our
experiencing a significant delay in delivery, or substantial shortage, of wafers
and possibly in higher fabrication fees.

<PAGE>   22

CHANGES IN CURRENT OR FUTURE LAWS OR REGULATIONS OR THE IMPOSITION OF NEW LAWS
OR REGULATIONS BY THE FCC, OTHER FEDERAL OR STATE AGENCIES OR FOREIGN
GOVERNMENTS COULD IMPEDE THE SALE OF OUR PRODUCTS OR OTHERWISE HARM OUR
BUSINESS.

        The Federal Communications Commission has broad jurisdiction over each
of our target markets. Although current FCC regulations and the laws and
regulations of other federal or state agencies are not directly applicable to
our products, they do apply to much of the equipment into which our products are
incorporated. As a result, the effects of regulation on our customers or the
industries in which they operate may, in turn, materially and adversely impact
our business, financial condition and results of operations. FCC regulatory
policies that affect the ability of cable operators or telephone companies to
offer certain services or other aspects of their business may impede the sale of
our products. For example, in the past we have experienced delays when products
incorporating our chips failed to comply with FCC emissions specifications. We
may also be subject to regulation by countries other than the United States.
Foreign governments may impose tariffs, duties and other import restrictions on
components that we obtain from non-domestic suppliers and may impose export
restrictions on products that we sell internationally. These tariffs, duties or
restrictions could materially and adversely affect our business, financial
condition and results of operations. Changes in current laws or regulations or
the imposition of new laws and regulations in the United States or elsewhere
could also materially and adversely affect our business.

CERTAIN OF OUR DIRECTORS, EXECUTIVE OFFICERS AND THEIR AFFILIATES CAN CONTROL
THE OUTCOME OF MATTERS THAT REQUIRE THE APPROVAL OF OUR SHAREHOLDERS, AND
ACCORDINGLY WE WILL NOT BE ABLE TO ENGAGE IN CERTAIN TRANSACTIONS WITHOUT THEIR
APPROVAL.

        As of September 30, 1999, our directors and executive officers
beneficially owned approximately 39.4% of our outstanding common stock and 66.9%
of the total voting control held by our shareholders. In particular, as of
September 30, 1999, our two founders, Dr. Henry T. Nicholas III and Dr. Henry
Samueli, beneficially owned a total of approximately 37.2% of our outstanding
common stock and 63.6% of the total voting control held by our shareholders.
Accordingly, these shareholders currently have enough voting power to control
the outcome of matters that require the approval of our shareholders. These
matters include the election of a majority of our Board of Directors, the
issuance of additional shares of Class B common stock and the approval of any
significant corporate transaction, including a merger, consolidation or sale of
substantially all of our assets. In addition, these insiders currently also
control the management of our business. Because of their significant stock
ownership, we will not be able to engage in certain transactions without the
approval of these shareholders. These transactions include proxy contests,
mergers, tender offers, open market purchase programs or other purchases of our
Class A common stock that could give our shareholders the opportunity to receive
a higher price for their shares than the prevailing market price at the time of
these purchases.

OUR STOCK PRICE IS HIGHLY VOLATILE. ACCORDINGLY, YOU MAY NOT BE ABLE TO RESELL
YOUR SHARES OF COMMON STOCK AT OR ABOVE THE PRICE YOU PAID FOR THEM.

        The market price of our Class A common stock has fluctuated
substantially in the past and is likely to continue to be highly volatile and
subject to wide fluctuations. Since our initial public offering in April 1998,
our Class A common stock has traded at prices as low as $23.50 and as high as
$215.25 per share. These fluctuations have occurred and may continue to occur in
response to various factors, many of which we cannot control, including:

        o quarter-to-quarter variations in our operating results;

        o announcements of technological innovations or new products by our
          competitors, customers or us;

        o general conditions in the semiconductor industry and
          telecommunications and data communications equipment markets;

        o changes in earnings estimates or investment recommendations by
          analysts;

        o changes in investor perceptions; or


                                       22
<PAGE>   23

        o changes in expectations relating to our products, plans and strategic
          position or those of our competitors or customers.

        In addition, the market prices of securities of Internet-related and
other high technology companies have been especially volatile. This volatility
has significantly affected the market prices of securities of many technology
companies for reasons frequently unrelated to the operating performance of the
specific companies. Accordingly, you may not be able to resell your shares of
common stock at or above the price you paid. In the past, companies that have
experienced volatility in the market price of their securities have been the
subject of securities class action litigation. If we were the object of a
securities class action litigation, it could result in substantial losses and
divert management's attention and resources from other matters.

OUR PRODUCTS AND INTERNAL INFORMATION SYSTEMS AND THE PRODUCTS AND SYSTEMS OF
OUR CUSTOMERS AND THE THIRD PARTY SUPPLIERS WHO FABRICATE, TEST AND ASSEMBLE OUR
PRODUCTS MAY BE NEGATIVELY IMPACTED BY YEAR 2000 COMPLIANCE PROBLEMS.

        Many existing computer systems and applications and other control
devices use only two digits to identify a year in the date field. These systems
and software applications will need to accept four digit entries to distinguish
21st century dates from 20th century dates. As a result, these systems and
applications will need to be upgraded to comply with the Year 2000 requirements
or risk system failure, miscalculations or other disruptions to normal business
activities.

        We are currently evaluating our Year 2000 readiness, both in terms of
the compliance of our products and the compliance of our information systems and
applications which monitor all aspects of our business, including financial
systems, customer services, marketing information, infrastructure and
telecommunications equipment. We are presently updating our products and
internal information systems, but we may not be able to complete these upgrades
in a timely manner or at reasonable costs. We also may not be able to anticipate
the extent of the Year 2000 impact until the Year 2000 arrives due to the
interaction between our own systems and products and the systems and products of
third parties. We believe our greatest exposure to Year 2000 risks relates to
the readiness of the third party suppliers who fabricate, assemble and test our
products and of our customers, who incorporate our products into their own
products. Any failure of these third parties to resolve their own Year 2000
issues in a timely manner could cause a material disruption in our business and
affect the marketability of our products.

        We also rely on the external systems of other third parties such as
creditors, financial organizations, governmental entities and other suppliers,
both domestic and international, to provide us with accurate data. Our business
could be materially and adversely affected if any of these third parties
experience disruptions in their operations or if an economic crisis or general
widespread problems result from systems that are not Year 2000 compliant.
Although we are working on contingency plans to address these issues, any
contingency plans that we implement may not be adequate to meet our needs
without disrupting our business or without causing delays and inefficiencies
inherent in conducting operations in an alternative manner. If we fail to
address any of the foregoing Year 2000 risks, our business, financial condition
and results of operations may be materially and adversely affected.

WE MAY NEED TO RAISE ADDITIONAL CAPITAL IN THE FUTURE THROUGH THE ISSUANCE OF
ADDITIONAL EQUITY OR CONVERTIBLE DEBT SECURITIES OR BY BORROWING MONEY, AND
ADDITIONAL FUNDS MAY NOT BE AVAILABLE ON TERMS ACCEPTABLE TO US.

        We believe that the cash, cash equivalents and investments on hand and
the cash we expect to generate from operations will be sufficient to meet our
capital needs for at least the next twelve months. However, it is possible that
we may need to raise additional funds to fund our activities beyond the next
year. We could raise these funds by selling more stock to the public or to
selected investors, or by borrowing money. In addition, even though we may not
need additional funds, we may still elect to sell additional equity securities
or obtain credit facilities for other reasons. We may not be able to obtain
additional funds on favorable terms, or at all. If adequate funds are not
available, we may be required to curtail our operations significantly or to
obtain funds through arrangements with strategic partners or others that may
require us to relinquish rights to certain technologies or potential markets. If
we raise additional funds by issuing additional equity or convertible debt
securities, the ownership percentages of


                                       23
<PAGE>   24

existing shareholders would be reduced. In addition, the equity or debt
securities that we issue may have rights, preferences or privileges senior to
those of the holders of our common stock.

        It is possible that our future capital requirements may vary materially
from those now planned. The amount of capital that we will need in the future
will depend on many factors, including:

        o the market acceptance of our products;

        o the levels of promotion and advertising that will be required to
          launch our products and achieve and maintain a competitive position in
          the marketplace;

        o volume price discounts;

        o our business, product, capital expenditure and research and
          development plans and technology roadmap;

        o the levels of inventory and accounts receivable that we maintain;

        o capital improvements to new and existing facilities;

        o technological advances;

        o our competitors' response to our products; and

        o our relationships with our suppliers and customers.

        In addition, we may require additional capital to accommodate planned
growth, hiring, infrastructure and facility needs or to consummate acquisitions
of other businesses, products or technologies.

OUR ARTICLES OF INCORPORATION AND BYLAWS CONTAIN ANTI-TAKEOVER PROVISIONS THAT
COULD ADVERSELY AFFECT THE PRICE OF OUR COMMON STOCK.

        Our articles of incorporation and bylaws contain provisions that may
prevent or discourage a third party from acquiring us, even if the acquisition
would be beneficial to our shareholders. In addition, we have in the past issued
and will in the future issue shares of Class B common stock in connection with
certain acquisitions, upon exercise of certain stock options, and for other
purposes. Those shares have superior voting rights entitling the holder to ten
votes for each share held on matters that we submit to a shareholder vote (as
compared with one vote per share in the case of our publicly-held Class A common
stock). Our Board of Directors also has the authority to fix the rights and
preferences of shares of our preferred stock and to issue these shares without a
shareholder vote. It is possible that the provisions in our charter documents,
the existence of supervoting rights by holders of our Class B common stock, and
our officers' ownership of a majority of the Class B common stock and the
ability of our Board of Directors to issue preferred stock may prevent parties
from acquiring us. In addition, these factors may discourage third parties from
bidding for our Class A common stock at a premium over the market price for this
stock. Finally, these factors may also materially and adversely affect the
market price of our Class A common stock, and the voting and other rights of the
holders of our Class A common stock.

QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK

Investment Portfolio

        We do not use derivative financial instruments in our non-trading
investment portfolio. We place our investments in instruments that meet high
credit quality standards, as specified in our investment policy guidelines; the
policy also limits the amount of credit exposure to any one issue, issuer or
type of instrument. We do not anticipate any material loss with respect to our
investment portfolio.

        The table below provides information about our non-trading investment
portfolio. For investment securities, the table presents principal cash flows
and related weighted average fixed interest rates by expected maturity dates.
Our investment policy requires that all investments mature in three years or
less, with a weighted average maturity of no longer than one year.

                         REPORT OF INDEPENDENT AUDITORS

Board of Directors and Shareholders
Broadcom Corporation

        We have audited the accompanying consolidated balance sheets of Broadcom
Corporation (formed as a result of the business combinations of Broadcom
Corporation and Maverick Networks, Epigram, Inc., Armedia, Inc., HotHaus
Technologies Inc., and AltoCom, Inc.) as of December 31, 1998 and 1997, and the
related consolidated statements of operations, shareholders' equity and cash
flows for each of the three years in the period ended December 31, 1998. The
consolidated financial statements give retroactive effect to the business
combinations of Broadcom Corporation and Maverick Networks, Epigram, Inc., and
Armedia, Inc. on May 31, 1999, and HotHaus Technologies Inc. and AltoCom, Inc.
on August 31, 1999, which have been accounted for using the pooling-of-interests
method as described in the notes to the consolidated financial statements. Our
audits also included the financial statement schedule listed in Item 5. These
financial statements and schedule are the responsibility of the management of
Broadcom Corporation. Our responsibility is to express an opinion on these
financial statements and schedule based on our audits. We did not audit the
financial statements of Maverick Networks, Epigram, Inc., and AltoCom, Inc.,
which statements reflect aggregate total assets constituting $19.9 million for
1998 and $11.5 million for 1997 of the related consolidated financial statement
totals, and which contributed aggregate net losses of $10.1 million, $3.7
million and $429,000 for the years ended December 31, 1998, 1997 and 1996,
respectively. Those statements were audited by other auditors whose reports have
been furnished to us, and our opinion, insofar as it relates to data included
for Maverick Networks, Epigram, Inc., and AltoCom, Inc., is based solely on the
reports of the other auditors.

        We conducted our audits in accordance with generally accepted auditing
standards. Those standards require that we plan and perform the audit to obtain
reasonable assurance about whether the financial statements are free of material
misstatement. An audit includes examining, on a test basis, evidence supporting
the amounts and disclosures in the financial statements. An audit also includes
assessing the accounting principles used and significant estimates made by
management, as well as evaluating the overall financial statement presentation.
We believe that our audits provide a reasonable basis for our opinion.

        In our opinion, based on our audits and the reports of other auditors,
the financial statements referred to above present fairly, in all material
respects, the consolidated financial position of Broadcom Corporation at
December 31, 1998 and 1997, and the consolidated results of its operations and
its cash flows for each of the three years in the period ended December 31,
1998, after giving retroactive effect to the business combinations of Broadcom
Corporation and Maverick Networks, Epigram, Inc., Armedia, Inc., HotHaus
Technologies Inc., and AltoCom, Inc., as described in the notes to the
consolidated financial statements, in conformity with generally accepted
accounting principles. Also, in our opinion, the related financial statement
schedule, when considered in relation to the basic financial statements taken as
a whole, presents fairly in all material respects the information set forth
therein.

                   NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

1. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

THE COMPANY

        Broadcom Corporation (the "Company") is a leading provider of highly
integrated silicon solutions that enable broadband digital transmission of
voice, data and video content to and throughout the home and within the business
enterprise. The Company's products enable the high-speed transmission of data
over existing communications infrastructures, most of which were not originally
intended for digital data transmission. Using proprietary technologies and
advanced design methodologies, the Company designs, develops and supplies
integrated circuits for a number of the most significant broadband
communications markets, including the markets for cable set-top boxes, cable
modems, high-speed office networks, home networking, direct broadcast satellite
and terrestrial digital broadcast, and digital subscriber lines.

BASIS OF PRESENTATION

        The consolidated financial statements include the accounts of the
Company and its wholly-owned subsidiaries. All significant intercompany accounts
and transactions have been eliminated.

USE OF ESTIMATES

        The preparation of financial statements in conformity with generally
accepted accounting principles requires management to make estimates and
assumptions that affect the amounts reported in the financial statements and
accompanying notes. Actual results could differ from those estimates.
Significant estimates made in preparing the financial statements include the
allowance for doubtful accounts and sales returns, inventory reserves, warranty
reserves and income tax valuation allowances.

REVENUE RECOGNITION

        Revenue from product sales is recognized at the time of shipment.
Provision is made currently for estimated product returns. Development revenue
is recognized when earned. Revenue from licensed software is recognized at the
time of shipment, provided the Company has vendor-specific objective evidence of
the fair value of each element of the software offering. Revenue from
post-contract customer support and any other future deliverables is deferred
and earned over the support period or as contract elements are delivered.

CONCENTRATION OF CREDIT RISK

        The Company sells the majority of its products throughout North America,
Europe and Asia. Sales to the Company's recurring customers are generally made
on open account while sales to occasional customers are typically made on a
C.O.D. basis. The Company performs periodic credit evaluations of its ongoing
customers and generally does not require collateral. Reserves are maintained for
potential credit losses, and such losses have generally been minimal and within
management's expectations.

        The Company invests its excess cash in deposits with major banks, in
U.S. Treasury and U.S. agency obligations and in debt securities of corporations
with strong credit ratings and in a variety of industries. It is the Company's
policy to invest in instruments that have a final maturity of no longer than
three years, with a portfolio weighted average maturity of not more than one
year.

FAIR VALUE OF FINANCIAL INSTRUMENTS

        The Company's financial instruments consist principally of cash and cash
equivalents, short-term and long-term investments, accounts receivable, accounts
payable, and borrowings. The Company believes all of the financial instruments'
recorded values approximate current values.


                                       31
<PAGE>   32

CASH AND CASH EQUIVALENTS

        Cash and cash equivalents consist of cash and short-term investments
with original maturities of ninety days or less.

INVESTMENTS

        The Company accounts for its investments in debt securities under
Financial Accounting Standards Board ("FASB") Statement No. 115, Accounting for
Certain Investments in Debt and Equity Securities. Management determines the
appropriate classification of such securities at the time of purchase and
reevaluates such classification as of each balance sheet date. The investments
are adjusted for amortization of premiums and discounts to maturity and such
amortization is included in interest income. Realized gains and losses and
declines in value judged to be other than temporary are determined based on the
specific identification method and are reported in the statement of operations.

INVENTORY

        Inventory is stated at the lower of cost (first-in, first-out) or market
and consists of the following:

LONG-LIVED ASSETS

        Effective January 1, 1996, the Company adopted FASB Statement No. 121,
Accounting for the Impairment of Long-Lived Assets and for Long-Lived Assets to
be Disposed of, which requires impairment losses to be recorded on long-lived
assets used in operations when indicators of impairment are present.
Implementation of Statement No. 121 had no impact on the consolidated financial
statements of the Company.

INCOME TAXES

        The Company utilizes the liability method of accounting for income taxes
as set forth in FASB Statement No. 109, Accounting for Income Taxes. Under the
liability method, deferred taxes are determined based on the differences between
the financial statement and tax bases of assets and liabilities using enacted
tax rates.


                                       32

STOCK-BASED COMPENSATION

        The Company accounts for stock-based awards to employees in accordance
with Accounting Principles Board Opinion No. 25, Accounting for Stock Issued to
Employees (APB 25) and has adopted the disclosure-only alternative of FASB
Statement No. 123, Accounting for Stock-Based Compensation.

EARNINGS PER SHARE

        In 1997, the FASB issued Statement No. 128, Earnings Per Share, which
replaced the calculation of primary and fully diluted earnings per share with
basic and diluted earnings per share. Unlike primary earnings per share, basic
earnings per share excludes any dilutive effects of options, warrants and
convertible securities. Diluted earnings per share is similar to fully diluted
earnings per share. All earnings per share amounts for all periods have been
presented to conform to the Statement No. 128 requirements and the accounting
rules set forth in Staff Accounting Bulletin 98 issued by the Securities and
Exchange Commission on February 3, 1998.

        The following table sets forth the computation of earnings (loss) per
share:

RESEARCH AND DEVELOPMENT EXPENDITURES

        Research and development expenditures are expensed in the period
incurred.

WARRANTY

        The Company provides a one-year warranty on all products and records a
related provision for estimated warranty costs at the date of sale. The
estimated warranty liability at December 31, 1998 and 1997 was $2.0 million and
$150,000, respectively.

COMPREHENSIVE INCOME

        Effective January 1, 1998, the Company adopted FASB Statement No. 130,
Reporting Comprehensive Income, which establishes standards for reporting and
displaying comprehensive income and its components in the consolidated financial
statements. For the years ended December 31, 1998, 1997 and 1996, the Company
did not have any components of comprehensive income as defined in Statement No.
130.

SEGMENTS OF A BUSINESS ENTERPRISE

        Effective January 1, 1998, the Company adopted FASB Statement No. 131,
Disclosures about Segments of an Enterprise and Related Information. Statement
No. 131 superseded FASB Statement No. 14, Financial Reporting for Segments of a
Business Enterprise. Statement No. 131 establishes standards for the way that
public business


                                       33
<PAGE>   34

enterprises report information about operating segments in annual consolidated
financial statements and requires that those enterprises report selected
information about operating segments in interim financial reports. Statement No.
131 also establishes standards for related disclosures about products and
services, geographic areas, and major customers. The adoption of Statement No.
131 did not affect the consolidated results of operations or financial position
of the Company.

STATEMENT OF CASH FLOWS

        For purposes of the statement of cash flows, the Company considers
investment securities with original maturities of ninety days or less to be cash
equivalents.

RECLASSIFICATIONS

        Certain amounts in the 1997 and 1996 consolidated financial statements
have been reclassified to conform to the current year presentation.

RECENT ACCOUNTING PRONOUNCEMENTS

        In June 1998, the FASB issued Statement No. 133, Accounting for
Derivative Instruments and Hedging Activities, which establishes new standards
for recording derivatives in interim and annual financial statements. This
statement requires recording all derivative instruments as assets or
liabilities, measured at fair value. Statement No. 133 is effective for fiscal
years beginning after June 15, 1999. Management does not anticipate that the
adoption of the new statement will have a significant impact on the consolidated
results of operations or financial position of the Company.

2. BUSINESS COMBINATIONS

Pooling-of-Interests Transactions

        On May 31, 1999, the Company completed the acquisitions of Maverick
Networks ("Maverick"), Epigram, Inc. ("Epigram"), and Armedia, Inc. ("Armedia").
Maverick develops highly integrated silicon for multi-layer switching equipment
in enterprise networks, Epigram makes advanced semiconductor products for
high-speed home networking, and Armedia is a developer of high performance
digital video decoders. In connection with the acquisitions, the Company issued
6,363,822 shares of its Class B common stock and reserved an additional 666,462
shares of its Class B common stock for issuance upon exercise of outstanding
employee stock options, warrants and other rights.

        On August 31, 1999 the Company completed the acquisitions of HotHaus
Technologies Inc. ("HotHaus") and AltoCom, Inc. ("AltoCom"). HotHaus is a
provider of OpenVoIP(TM) (Voice over Internet Protocol) embedded communications
software that enables transmission of digital voice, fax and data packets over
data networks, including the Internet. AltoCom offers complete software data/fax
modem implementations for general purpose embedded processors, PC CPUs and
digital signal processors. In connection with the acquisitions, the Company
issued 3,361,571 shares of its Class B common stock and reserved an additional
258,263 shares of its Class B common stock for issuance upon exercise of
outstanding employee stock options and other rights.

        Each of the acquisitions was accounted for as a pooling of interests.
Accordingly, the Company's historical consolidated financial statements have
been restated to include the pooled operations of Maverick, Epigram,

        The restated consolidated financial statements give effect to the
business combinations as if they had occurred prior to the beginning of each
period presented and reflect adjustments made to (i) conform the accounting
policies of the combined companies and (ii) eliminate intercompany accounts and
transactions. No adjustments have been made to give effect to
acquisition-related expenses, which have been recorded in the fiscal year ending
December 31, 1999.

        The historical numbers of shares of Maverick, Epigram, Armedia, HotHaus
and AltoCom common stock and common stock equivalents have been converted to
equivalent shares of the Company's common stock based on the applicable exchange
ratios used to convert the respective outstanding shares of each acquired
company on the respective acquisition dates.

        AltoCom recorded approximately $2.2 million in the year ended December
31, 1998, representing accretion to redemption value of its preferred stock.
Such amount has been presented as a reduction to retained earnings in the
accompanying Consolidated Statements of Shareholders' Equity.

3. INVESTMENTS

        At December 31, 1998, all of the Company's investments were in

5. LONG-TERM DEBT

        In March 1995, the Company entered into a Loan and Security Agreement
with Silicon Valley Bank ("SVB") which, as amended in June 1997, provided for a
$3.0 million term loan and a $3.0 million revolving credit facility. A $500,000
letter of credit facility was also included in the agreement provided that
sufficient credit was available under the other two facilities. During 1997, the
full amount of the $3.0 million term loan facility was utilized at an interest
rate of SVB's prime rate as announced from time to time plus .5%. At December
31, 1997, $2.5 million was outstanding under the term loan facility. During
1998, the Company repaid all outstanding indebtedness under this facility. The
Loan and Security Agreement expired on April 5, 1998.

        The following is a summary of the Company's long-term debt and other

7. SHAREHOLDERS' EQUITY

COMMON STOCK

        In February 1998, the Board of Directors approved the amendment and
restatement of the articles of incorporation to authorize 200,000,000 shares of
Class A common stock, 100,000,000 shares of Class B common stock and 10,000,000
shares of preferred stock. Effective with the amendment, all outstanding common
stock was converted into Class B common stock and all outstanding stock options
became exercisable for shares of Class B common stock. The shares of Class A
common stock and Class B common stock are substantially identical,


                                       37
<PAGE>   38

except that holders of Class A common stock are entitled to one vote for each
share held, and holders of Class B common stock are entitled to ten votes for
each share held on all matters submitted to a vote of the shareholders. In
addition, holders of Class B common stock are entitled to vote separately on the
proposed issuance of additional shares of Class B common stock. The Class A
common stock and Class B common stock are sometimes collectively referred to
herein as the "common stock."

STOCK SPLIT

        In February 1998, the Board of Directors approved a 3-for-2 stock split,
effective March 9, 1998, of the Company's common stock. All share and per share
amounts in the accompanying consolidated financial statements have been
retroactively restated to reflect the stock split.

SALE OF SHARES TO CISCO SYSTEMS, INC.

        On February 3, 1998, Cisco Systems, Inc. ("Cisco Systems") exercised its
option to purchase 1,000,000 shares of Class A common stock upon consummation of
the Company's initial public offering at a price per share equal to the initial
public offering price, net of underwriting discounts and commissions. Such
option was granted to Cisco Systems in connection with the Development and
License Agreement entered into between the Company and Cisco Systems effective
in September 1996, as amended on February 3, 1998.

INITIAL PUBLIC OFFERING AND FOLLOW-ON OFFERING

        In April 1998, the Company completed its initial public offering (the
"Offering") of 8,050,000 shares of its Class A common stock. Of these shares,
the Company sold 6,240,000 shares and selling shareholders sold 1,810,000 shares
at a price of $12.00 per share. In addition, the Company sold 1,000,000 shares
of Class A common stock to Cisco Systems, in a concurrent registered offering
that was not underwritten, at a price of $11.16 per share. The Company received
aggregate net proceeds from the Offering and the sale of shares to Cisco Systems
of approximately $79.2 million in cash (net of underwriting discounts and
commissions and offering costs). Upon consummation of the Offering, all
outstanding shares of the Company's Convertible preferred stock were
automatically converted into an aggregate of 16,907,034 shares of Class B common
stock.

        In October 1998, the Company completed a follow-on public offering. Of
the 6,900,000 shares of Class A common stock offered, the Company sold 940,000
shares and selling shareholders sold 5,960,000 shares, at a price of $34.50 per
share. The Company received net aggregate proceeds of approximately $30.5
million after deducting underwriting discounts and commissions and offering
costs.

        Each share of Series A, B, C and D preferred stock is convertible into
six shares of Class B common stock. Each share of Series E preferred stock is
convertible into three shares of Class B common stock. Such shares may be
converted at any time at the option of the holder and automatically convert into
Class B common stock in the event of an underwritten public offering of the
Company's common stock as long as the value of the Company for purposes of the
public offering is not less than $45,000,000.


                                       38
<PAGE>   39

        Holders of the Company's Series A, B, C, D and E preferred stock are
entitled to noncumulative annual dividends of $0.20 per share in preference to
holders of common stock when declared by the Board of Directors. No such cash
dividends have been declared since the inception of the Company.

        In the event of the liquidation of the Company, holders of Series A, B,
C, D and E preferred stock are entitled to receive an amount per share equal to
the original issuance price plus declared and unpaid dividends, prior and in
preference to any distribution of assets to holders of common stock.

        The holders of Series A, B, C, D and E preferred stock have the right to
purchase additional shares of stock in order to maintain their ownership
percentage in the event of certain future sales of stock by the Company.

        Holders of Series A, B, C, D and E preferred stock are entitled to the
same number of votes per share on any and all matters submitted to a shareholder
vote as the Class B common stock into which the preferred stock is convertible.

        Upon consummation of the Offering in April 1998, each share of Series A,
B, C and D preferred stock was converted into six shares of Class B common
stock, and each share of Series E preferred stock was converted into three
shares of Class B common stock. As of December 31, 1998, no shares of preferred
stock were outstanding.

ISSUANCE OF WARRANTS

        In April 1998, the Company issued a Class A common stock Purchase
Warrant (the "Warrant") to Brobeck, Phleger & Harrison LLP, counsel to the
Company, to purchase up to 20,000 shares of the Company's Class A common stock
at an exercise price of $12.00 per share. The Warrant is exercisable from April
30, 1999 to April 30, 2000. The Warrant was issued in a transaction exempt from
registration by virtue of Section 4(2) of the Securities Act of 1933, as
amended.

1998 EMPLOYEE STOCK PURCHASE PLAN

        The 1998 Employee Stock Purchase Plan (the "Purchase Plan"), adopted on
February 3, 1998, allows employees to designate up to 15% of their total
compensation to purchase shares of the Company's Class A common stock at 85% of
fair market value (calculated in the manner provided in the Purchase Plan).
1,500,000 shares of Class A common stock have been reserved for issuance under
the Purchase Plan. In 1998, 169,128 shares were purchased at a price of $10.20
per share.

1994 STOCK OPTION PLAN

        Under the Company's Amended and Restated 1994 Stock Option Plan (the
"1994 Plan"), the Board of Directors or a Committee consisting of two or more
members of its Board of Directors is authorized to grant options to purchase the
Company's Class B common stock to its employees, members of the Board of
Directors and certain consultants. Incentive options may be granted at an
exercise price equal to or greater than 100% of the fair market value of the
underlying Class B common stock at the date of grant, and non-qualified options
may be granted at an exercise price equal to or greater than 85% of the fair
market value of the underlying Class B common stock on the date of grant.

        The options are exercisable immediately upon issuance and generally have
a term of ten years. The Company reserves the right to repurchase all unvested
shares held by the participant upon the participant's termination at the
original purchase price. Fully vested options not purchased by the participant
within three months after termination are canceled and returned to the plan. The
Board of Directors or the Committee determines the vesting schedule at the time
of issuance. Stock options generally vest at the rate of 25% after one year and
ratably on a monthly basis for three years thereafter. Until the Company's
Offering in April 1998, the Company had the right of first refusal to purchase
any shares of common stock issued under the 1994 Plan.

        At the discretion of the Board of Directors or the Committee, the
Company may make secured loans to option holders in amounts up to the exercise
price of their options plus related taxes or permit the option holder to pay the
exercise price in installments over a determined period. During 1998, 1997 and
1996, the Company loaned


                                       39
<PAGE>   40

$191,000, $2,614,00 and $416,000, respectively, to employees for the exercise of
options. These notes are full-recourse, are secured by the shares of stock, are
interest bearing with rates ranging from 5.6% to 6.5%, are due between three and
five years from the exercise date and must be ratably repaid upon sale of the
underlying shares of stock.

        During 1997 and 1996, the Company's Board of Directors approved
increases in the number of shares of Class B common stock reserved and available
for issuance under the 1994 Plan of 19,200,000 shares and 9,000,000 shares,
respectively. A total of 39,000,000 shares of Class B common stock was available
for issuance at December 31, 1998 and 1997. In April 1998, all amounts reserved
for issuance under the 1994 Plan were assumed by the 1998 Plan. As of December
31, 1998, no shares were available for grant under the 1994 Plan.

1998 STOCK INCENTIVE PLAN

        The Company's 1998 Stock Incentive Plan (the "1998 Plan"), which became
effective on April 8, 1998 (the "Plan Effective Date"), is intended to serve as
the successor equity incentive program to the Company's 1994 Plan and the
Company's 1998 Special Stock Option Plan (the "Special Plan"). The Special Plan
was adopted to permit options to be granted with terms permitted by the 1998
Plan prior to the 1998 Plan becoming effective. A total of 4,000,000 shares of
Class B common stock were authorized for issuance under the Special Plan. A
total of 31,896,878 shares of common stock have been authorized for issuance
under the 1998 Plan. Such share reserve consists of (i) the number of shares
which remain available for issuance under the 1994 Plan and the Special Plan on
the Plan Effective Date, including the shares subject to outstanding options,
and (ii) an additional increase of 6,000,000 shares of Class A common stock. Any
unvested shares of Class B common stock issued under the 1994 Plan or the
Special Plan repurchased by the Company after the Plan Effective Date will be
added to the reserve of Class A common stock available for issuance under the
1998 Plan. In addition, the number of shares of Class A common stock reserved
for issuance under the 1998 Plan will automatically increase on the first
trading day of each calendar year, beginning in calendar year 1999. The increase
will be equal to 3% of the total number of shares of Class A common stock
outstanding on the last trading day of the immediately preceding calendar year.

        In April 1998, outstanding options under the 1994 Plan and the Special
Plan were incorporated into the 1998 Plan, and no further option grants may be
made under the 1994 Plan or the Special Plan. The incorporated options will
continue to be governed by their existing terms, unless the Plan Administrator
elects to extend one or more features of the 1998 Plan to those options.

        The Company recorded approximately $7.6 million and $1.2 million of net
deferred compensation in the years ended December 31, 1998 and 1997,
respectively, for the difference between the exercise price of certain of the
Company's stock options granted and the deemed fair market value of the
underlying Class B common stock. Such


                                       41
<PAGE>   42

amounts have been presented as a reduction to shareholders' equity and are being
amortized ratably over the vesting period of the applicable options. The Company
amortized an aggregate of $1.8 million and $66,000 of deferred compensation in
1998 and 1997, respectively. The remaining balance of total deferred
compensation will be amortized ratably over the vesting period of the applicable
options.

PRO FORMA DISCLOSURES OF THE EFFECT OF STOCK-BASED COMPENSATION PLANS

        Pro forma information regarding results of operations and net income
(loss) per share is required by FASB Statement No. 123 for stock-based awards to
employees as if the Company had accounted for such awards using a valuation
method permitted under Statement No. 123.

        The value of the Company's stock-based awards granted to employees prior
to the Offering in April 1998 was estimated using the minimum value method,
which does not consider stock price volatility. Stock-based awards granted in
1998 subsequent to the Offering have been valued using the Black-Scholes option
pricing model. Among other things, the Black-Scholes model considers the
expected volatility of the Company's stock price, determined in accordance with
Statement No. 123, in arriving at an option valuation. Estimates and other
assumptions necessary to apply the Black-Scholes model may differ significantly
from assumptions used in calculating the value of options granted prior to the
Offering under the minimum value method.

        The fair value of the Company's stock-based awards granted to employees
prior to the Offering was estimated assuming no expected dividends, a weighted
average expected life of 3.5 years, a weighted average risk-free interest rate
of 6.0% and no expected volatility. The fair value of options granted after the
Offering was estimated assuming no expected dividends, a weighted average
expected life of 1.5 years from vest date, a weighted average risk-free interest
rate of 5.0% and an expected volatility of .74. The fair value of employee stock
purchase rights was estimated assuming no expected dividends, a weighted average
expected life of 15 months, a weighted average risk-free interest rate of 5.0%
and an expected volatility of .74.

        The weighted-average fair value of options granted during 1998, 1997 and
1996 were $12.51, $.36 and $.06, respectively. The weighted-average fair value
of employee stock purchase rights granted in 1998 was $6.15. For pro forma
purposes, the estimated value of the Company's stock-based awards to employees
is amortized over the vesting period of the underlying instruments. The results
of applying Statement No. 123 to the Company's stock-based awards to employees
would approximate the following:

8. EMPLOYEE BENEFIT PLANS

        The Company sponsors a defined contribution 401(k) Savings and
Investment Plan, which was established in 1996, covering substantially all of
the Company's employees, subject to certain eligibility requirements. At its
discretion, the Company may make contributions to the plan. The Company made no
contributions to this plan in 1998, 1997 or 1996.

9. LITIGATION

        In December 1996 Stanford Telecommunications, Inc. ("STI") filed an
action against the Company in the United States District Court for the Northern
District of California. STI alleged that the Company's BCM3036, BCM3037,


                                       42
<PAGE>   43

BCM3300, BCM93220 and BCM93220B products infringed one of STI's patents (the
"'352 Patent"). STI sought an injunction as well as the recovery of monetary
damages, including treble damages for willful infringement, as to the products
listed above and potentially other products. The Company filed an answer and
affirmative defenses to STI's complaint, denying the allegations in STI's
complaint, and asserted a counterclaim requesting declaratory relief that the
Company was not infringing the '352 Patent and that the '352 Patent was invalid
and unenforceable. In May 1999 the Company brought a separate action against STI
and an STI subsidiary in California Superior Court for misappropriation of
certain Company trade secrets. On June 16, 1999 the parties entered into a
settlement agreement and agreed to dismiss with prejudice all claims and
counterclaims in both actions. Under the terms of the settlement agreement, STI
granted to the Company a worldwide, non-exclusive, royalty-free license to STI's
rights in patents and patent applications, and all inventions conceived, through
the date of the agreement, relating to any transmitter or receiver technology,
or design or invention capable of use over a coaxial cable transmission medium,
excluding patent claims specifically claiming Code Division Multiple Access
(CDMA) inventions. The Company also obtained the option to acquire licenses on
commercially reasonable terms to STI's patent claims based upon CDMA inventions
capable of use over a coaxial cable transmission medium, and STI agreed not to
bring any future action against the Company, its suppliers or customers for
patent infringement or trade secret misappropriation resulting from commercial
use of any of the Company's existing technology, designs or products. In
connection with the settlement, the Company made a one-time payment to STI and
the parties exchanged mutual releases. Neither party admitted any liability in
connection with the various actions.

        In April 1997 Sarnoff Corporation and Sarnoff Digital Communications,
Inc., now known as NxtWave Communications, Inc., (collectively, "Sarnoff") filed
a complaint in New Jersey Superior Court against the Company and five former
Sarnoff employees now employed by the Company (the "Former Employees") asserting
claims against the Former Employees for breach of contract, misappropriation of
trade secrets, and breach of the covenant of good faith and fair dealing, and
against the Company for inducing such actions. Those claims relate to the
alleged disclosure of certain technology of Sarnoff to the Company. The
complaint also asserted claims against the Company and the Former Employees for
unfair competition, misappropriation and misuse of trade secrets and
confidential, proprietary information of Sarnoff, and tortious interference with
present and prospective economic advantage, as well as a claim against the
Company alleging that it "illegally pirated" Sarnoff's employees. The complaint
sought to preliminarily and permanently enjoin the Company and the Former
Employees from utilizing any alleged Sarnoff trade secrets, and to restrain the
Former Employees from violating their alleged statutory and contractual duties
of confidentiality to Sarnoff by, for example, precluding them from working for
six months in any capacity relating to certain of the Company's programs. In May
1997 the Court denied Sarnoff's request for a temporary restraining order. On
February 2, 1999 the Court dismissed with prejudice Sarnoff's misappropriation
of trade secrets claims, and granted summary judgment dismissing all of
Sarnoff's remaining claims except claims based upon the Company's alleged
"pirating" of Sarnoff's employees. Trial of Sarnoff's "piracy"-related claims
commenced on February 22, and concluded on March 2, 1999. On April 27, 1999 the
Court issued an order and opinion dismissing with prejudice all remaining claims
that Sarnoff had against the Company. The Court found in the Company's favor on
all liability, causation, and damages issues. Subsequently the Court denied the
Company's petition for attorneys' fees in the case. Judgment on the Court's
February 2 and April 27 orders was entered on May 19, 1999. On July 1, 1999,
Sarnoff filed an appeal of both orders in the Superior Court of New Jersey,
Appellate Division. In October 1999 Sarnoff requested that the Appellate
Division dismiss the appeal and the court did so.

        In July 1997 the Company commenced an action against Sarnoff in the
California Superior Court alleging breach of contract, fraud, misappropriation
of trade secrets, false advertising, trade libel, intentional interference with
prospective economic advantage and unfair competition. The claims center on
Sarnoff's violation of a non-disclosure agreement entered into with the Company
with respect to limited use of certain of the Company's technology and on
inaccurate comparisons that the Company believes Sarnoff has made in its product
advertising and in statements to potential customers and others. This action was
removed to the United States District Court for the Central District of
California, and was stayed pending resolution of the New Jersey action described
in the preceding paragraph. Following trial in the New Jersey action, the
parties stipulated to lift the stay so that litigation of the California action
could go forward. Sarnoff then filed a motion for summary judgment in the
California case on the basis that the issues therein have been or should have
been previously litigated in the New Jersey action under the New Jersey "entire
controversy" doctrine. Following oral argument on August 16, 1999, the Court
granted Sarnoff's motion and dismissed Broadcom's claims on the grounds that
they should have been brought as part of the New Jersey action. The Company
believes that the California action involves facts, circumstances and claims


                                       43
<PAGE>   44

unrelated to those at issue in the New Jersey action, and has filed an appeal of
the District Court's ruling. No discovery has yet occurred in the case.

        In March 1998 Scott O. Davis, the Company's former Chief Financial
Officer, filed a complaint in California Superior Court against the Company and
its Chief Executive Officer, Henry T. Nicholas, III, alleging claims for fraud
and deceit, negligent misrepresentation, breach of contract, breach of fiduciary
duty, constructive fraud, conversion, breach of the implied covenant of good
faith and fair dealing, and declaratory relief. The claims related to Mr. Davis'
alleged ownership of 26,000 shares of Series D preferred stock originally
purchased by Mr. Davis in March 1996 (which shares would have converted into
156,000 shares of Class B common stock upon consummation of the Offering). The
purchase agreement between the Company and Mr. Davis contained a provision
permitting the Company to repurchase the shares in the event that Mr. Davis did
not continue to be employed by the Company for a certain period of time. After
Mr. Davis resigned in June 1997, the Company exercised its repurchase right. Mr.
Davis' complaint alleged that the repurchase right should not be enforceable
under several legal theories and sought unspecified damages and declaratory
relief. The Company asserted certain counterclaims against Mr. Davis. On March
19, 1999 the parties entered into a settlement agreement and agreed to dismiss
with prejudice all of the claims and counterclaims in the case. The settlement
was approved by the Court on April 5, 1999. The terms of the settlement are
confidential but the Company believes that they will not have a material effect
on its business, results of operations, financial condition or equity.

        In September 1998 Motorola, Inc. ("Motorola") filed a complaint in
United States District Court for the District of Massachusetts against AltoCom,
asserting that (i) AltoCom's V.34 and V.90 compliant software modem technology
infringes several patents owned by Motorola, (ii) AltoCom induces its V.34 and
V.90 licensees to infringe such patents, and (iii) AltoCom contributorily
infringes such patents. The complaint sought a preliminary and permanent
injunction against AltoCom as well as the recovery of monetary damages,
including treble damages for willful infringement. In October 1998 Motorola
affirmatively dismissed its case in the District of Massachusetts and filed a
substantially similar complaint in the United States District Court for the
District of Delaware. AltoCom has filed an answer and affirmative defenses to
the District of Delaware complaint. AltoCom has also asserted a counterclaim
requesting declaratory relief that AltoCom has not infringed the Motorola
patents and that such patents are invalid and/or unenforceable as well as a
counterclaim requesting declaratory and injunctive relief based on breach of
contract theory. AltoCom believes that it has strong defenses to Motorola's
claims on invalidity, noninfringement and inequitable conduct grounds. The
parties are currently in the initial stages of discovery in the action. The
Court has tentatively scheduled the first stage of trial for January 2001, with
a secondary stage scheduled for March 2001. AltoCom became a subsidiary of the
Company on August 31, 1999.

        Although AltoCom believes that it has strong defenses, a finding of
infringement by AltoCom in this action could lead to liability for monetary
damages (which could be trebled in the event that the infringement were found to
have been willful), the issuance of an injunction requiring that AltoCom
withdraw various products from the market, and indemnification claims by
AltoCom's customers or strategic partners, each of which events could have a
material adverse effect on the Company's business, financial condition and
results of operations.

        The Company is also involved in other legal proceedings, claims and
litigation arising in the ordinary course of business.

        The Company's pending lawsuits involve complex questions of fact and law
and could require the expenditure of significant costs and diversion of
resources to defend. Although management believes the outcome of the Company's
outstanding legal proceedings, claims and litigation will not have a material
adverse effect on the Company's business, results of operations or financial
condition, the results of litigation are inherently uncertain, and an adverse
outcome is at least reasonably possible. The Company is unable to estimate the
range of possible loss from outstanding litigation, and no amounts have been
provided for such matters in the accompanying consolidated financial statements.

        The Company does not own or operate a fabrication facility. Two outside
foundries in Asia currently supply substantially all of the Company's
semiconductor device requirements. Any sudden demand for an increased amount of
semiconductor devices or sudden reduction or elimination of any existing source
or sources of semiconductor devices could result in a material delay in the
shipment of the Company's products. In addition, substantially all of the
Company's products are assembled and tested by one of two third-party
subcontractors in Asia. The Company does not have long-term agreements with any
of these suppliers. Any problems associated with the fabrication facilities, or
the delivery, quality or cost of the Company's products could have a material
adverse effect on the Company's business, financial condition and results of
operations.
