1. BASIS OF PRESENTATION

    The accompanying unaudited condensed consolidated financial statements have
been prepared by Packeteer, Inc., pursuant to the rules and regulations of the
Securities and Exchange Commission ("SEC") and include the accounts of
Packeteer, Inc. and its wholly-owned subsidiaries ("Packeteer" or collectively
the "Company"). All significant intercompany accounts and transactions have been
eliminated in consolidation. Certain information and footnote disclosures,
normally included in financial statements prepared in accordance with generally
accepted accounting principles, have been condensed or omitted pursuant to such
rules and regulations. While in the opinion of the Company's management, the
unaudited financial statements reflect all adjustments (consisting only of
normal recurring adjustments) necessary for a fair statement of interim periods
presented, these financial statements and notes should be read in conjunction
with the audited consolidated financial statements and notes thereto, included
in the Company's Annual Report on Form 10-K for the year ended December 31, 2000
filed with the SEC on March 29, 2001.

    The results of operations for the three and six months ended June 30, 2001
are not necessarily indicative of results that may be expected for any other
interim period or for the full fiscal year ending December 31, 2001.

2. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

    REVENUE RECOGNITION

    The Company recognizes product revenue when it is realized or realizable and
earned. Generally, that occurs after the following events: the receipt of a
non-cancelable purchase order, the shipment of the product, the sales price is
fixed or determinable, and collection of the sales price is reasonably assured.
This policy is modified under certain circumstances as follows: Product revenue
on sales to major new distributors are recorded based on sell-through to the end
user customers until such time as the Company has established significant
experience with the distributor's product return and exchange activity. The
Company accrues for estimated customer returns following the guidance of
Statement of Financial Accounting Standards No. 48, "Revenue Recognition When
Right of Return Exists".

    Maintenance revenue on product sales is allocated and deferred based on
vendor specific objective evidence of fair value, generally established based on
renewal rates. The deferred revenues are then recognized ratably over the term
of the maintenance period.

    Upon shipment of products to its customers, the Company provides for the
estimated cost to repair or replace products that may be returned under
warranty. The Company's warranty period is typically 12 months from the date of
shipment to the end user customer.

    Revenue recognition for software transactions is accounted for pursuant to
the American Institute of Certified Public Accountants' (AICPA) Statement of
Position (SOP) 97-2, "Software Revenue Recognition" as modified by SOP 98-9,
"Modification of SOP 97-2, Software Revenue Recognition, with Respect to Certain
Transactions." SOP 97-2 generally requires revenue earned on software
arrangements involving multiple-elements to be allocated to each element based
on its relative fair value. The fair value of the element must be based on
objective evidence that is specific to the vendor. If a vendor does not have
objective evidence of the fair value of all elements in a multiple-element
arrangement, all revenue from the arrangement must be deferred until such
evidence exists or until all elements have been delivered, unless the only
undelivered element is post-contract customer support, in which case, the entire
fee is recognized over the support period.

    CASH AND CASH EQUIVALENTS

    The Company considers all highly liquid investments with a maturity from
date of purchase of three months or less to be cash equivalents. Cash and cash
equivalents consist primarily of cash on deposit with banks, money market
instruments and investments in commercial paper that are stated at cost which
approximates fair market value.



                                       6

    INVESTMENTS

    Management determines the appropriate classification of investment
securities at the time of purchase and reevaluates such designation as of each
balance sheet date. To date, all investment securities have been designated as
available-for-sale and are carried at fair value based on quoted market prices,
with unrealized gains and losses, net of tax, included in stockholders' equity
as a component of accumulated other comprehensive income and loss. Realized
gains and losses are included in other income, net. Interest and dividends on
all securities are included in other income, net. The cost of investments sold
is determined on the specific identification method.

    GOODWILL AND OTHER INTANGIBLE ASSETS

    The Company records goodwill when the cost of net identifiable assets
acquired exceeds the fair value of the assets. Goodwill and the cost of
identified intangible assets are amortized on a straight-line basis over three
years. The Company regularly performs reviews to determine if the carrying value
of these assets is impaired. The purpose for the review is to identify any facts
or circumstances, either internal or external, which indicate that the carrying
value of the assets cannot be recovered. No such impairment has been indicated
to date. If, in the future, management determines the existence of impairment
indicators, the Company would use undiscounted cash flows to initially determine
whether impairment should be recognized. If necessary, the Company would perform
a subsequent calculation to measure the amount of the impairment loss based on
the excess of the carrying value over the fair value of the impaired assets. If
quoted market prices for the assets are not available, the fair value would be
calculated using the present value of estimated expected future cash flows. The
cash flow calculation would be based on management's best estimates, using
appropriate assumptions and projections at the time. Effective Jan 1, 2002, the
Company will cease amortization of goodwill in accordance with SFAS No. 142
"Goodwill and Other Intangible Assets" (See Note 3).

    NET LOSS PER SHARE

    Basic and diluted net loss per share has been computed using the
weighted-average number of shares of common stock outstanding during the period,
less the weighted-average number of shares of common stock that are subject to
repurchase and in escrow related to the acquisition of Workfire International
Technologies, Inc. in September 2000. All warrants for common stock, outstanding
stock options and shares subject to repurchase have been excluded from the
calculation of diluted net loss per share as their inclusion would be
antidilutive for all periods presented.

    The following table presents the calculation of basic and diluted net loss
per share:

    OTHER COMPREHENSIVE LOSS

    The Company reports comprehensive income or loss in accordance with the
provisions of SFAS No. 130, "Reporting Comprehensive Income." SFAS No. 130
establishes standards for reporting comprehensive income and loss and its
components in financial statements. Comprehensive income or loss, as defined,
includes all changes in equity (net assets) during a period from non-owner
sources.

    SEGMENT REPORTING

    The Company has adopted the provisions of SFAS No. 131, "Disclosures about
Segments of an Enterprise and Related Information." The Company's chief
operating decision maker is considered to be the Company's CEO. The CEO reviews
financial information presented on a consolidated basis substantially similar to
the consolidated financial statements. Therefore, the Company has concluded that
it operates in one segment and accordingly has provided only the required
enterprise-wide disclosures.

    The Company operates in the United States and internationally and derives
its revenue from the sale of products and software licenses. The Company's
sales, marketing, and development efforts have been focused on the PacketShaper
family of products and PacketWiseTM software. For the three months ended June
30, 2001, sales to Alternative Technology, Inc. accounted for 20% of net
revenues and sales to Allasso accounted for 11% of net revenues. For the six
months ended June 30, 2001, one customer, Alternative Technology, Inc.,
accounted for 19% of net revenues. For the same periods in the prior year, one
customer, Alternative Technology, Inc., accounted for 16% and 12% of net
revenues, respectively.

3. RECENT ACCOUNTING PRONOUNCEMENTS

    In September 2000, the FASB issued SFAS No. 140, "Accounting for Transfers
and Servicing of Financial Assets and Extinguishments of Liabilities, a
replacement of FASB Statement No. 125." SFAS No. 140 supersedes and replaces the
guidance in FASB Statement No. 125, "Accounting for Transfers and Servicing of
Financial Assets and Extinguishments of Liabilities." SFAS No. 140 revises the
standards for accounting for securitizations and other transfers of financial
assets and collateral and requires certain disclosures. SFAS No. 140 is
effective for transfers of financial assets occurring after March 31, 2001. The
adoption of this standard did not have a material impact on the Company's
results of operations or financial position.

    In July, 2001, the FASB issued SFAS No. 141, "Business Combinations" and
SFAS No. 142, "Goodwill and Other Intangible Assets". SFAS No. 141 requires that
the purchase method of accounting be used for all business combinations
initiated after June 30, 2001. SFAS No. 142 changes the accounting for goodwill
from an amortization method to an impairment-only approach. Thus amortization of
goodwill, including goodwill recorded in past business combinations, will cease
upon adoption of that Statement, which for Packeteer will be January 1, 2002.

        OF OPERATIONS

    OVERVIEW

    Packeteer is a leading provider of application performance infrastructure
systems designed to provide enterprises and service providers a layer of control
for applications delivered across intranets, extranets and the Internet.
Packeteer's products --- powered by PacketWiseTM software --- are designed to
ensure end-to-end quality of service (QoS) for networked applications and
managed services, enhancing users' quality of experience through comprehensive
bandwidth, traffic, content, service-level and policy management. Packeteer's
PacketShaper family of products, the PacketShaper(R) and AppVantageTM systems,
integrates application discovery, analysis, control and reporting technologies
that are required for proactive application performance and bandwidth
management. The AppCeleraTM family of internet acceleration appliances employs
secure socket layer ("SSL") acceleration and advanced content compression,
transformation and caching technologies to improve response times of mission
critical enterprise, eBusiness and eCommerce web applications.

    Packeteer's products are deployed by Global 2000 corporations and service
providers, and sold through an established network of more than 100 VARs,
distributors, system-integrators and OEMs in more than 50 countries. Our
products are built on hardware platforms based on Intel-compatible
microprocessor technologies. In addition, PacketWise software is licensed by
major communications industry partners who integrate the software into specific
strategic networking solutions. We primarily use indirect channels, VARs,
distributors, system integrators and OEMs to leverage the reach of our sales
force and to obtain worldwide coverage. Our sales and marketing efforts are used
to develop brand awareness and support our indirect channels. We have
subsidiaries in Hong Kong, Japan, The Netherlands, the United Kingdom, Denmark,
Germany, Australia, France, Caymans and Canada. To date, we have shipped more
than 14,000 units.

    We were incorporated in January 1996. From our inception through January
1997, our operating activities related primarily to establishing a research and
development organization, developing and testing prototype designs, establishing
a sales and marketing organization and developing customer, vendor and
manufacturing relationships. We shipped our first product in February 1997.
Since



                                       9
<PAGE>   10

 then, we have focused on developing additional products and product
enhancements, building our worldwide indirect sales channel and establishing our
sales, marketing and customer support organizations. Since inception, we have
incurred significant losses and as of June 30, 2001, had an accumulated deficit
of $52.1 million.

    In order to further the growth of our business, we sold 4.6 million shares
of common stock in our initial public offering on July 28, 1999, which raised
approximately $62.6 million, net of fees and expenses.

    We have a limited operating history. We have not achieved profitability on a
quarterly or annual basis, and we anticipate that we will incur net losses for
at least the next several quarters. We expect to continue to incur significant
sales and marketing, product development, and administrative expenses and, as a
result, will need to generate significant quarterly revenues to achieve and
maintain profitability.

    RESULTS OF OPERATIONS

    The following table sets forth certain financial data as a percentage of net
revenues for the periods indicated. These historical operating results are not
necessarily indicative of the results for any future period.

</TABLE>


    NET REVENUES

    Our net revenues consist primarily of product sales and, to a lesser extent,
software licensing fees from OEM partners. Our product revenues consist of sales
of our PacketShaper, AppVantage and AppCelera lines of product.

    The Company recognizes product revenue when it is realized or realizable and
earned. Generally, that occurs after the following events: the receipt of a
non-cancelable purchase order, the shipment of the product, the sales price is
fixed or determinable, and collection of the sales price is reasonably assured.
This policy is modified under certain circumstances as follows. Product revenue
on sales to major new distributors are recorded based on sell-through to the end
user customers until such time the Company has established significant
experience with the distributor's product return and exchange activity. The
Company accrues for estimated customer returns following the guidance of
Statement of Financial Accounting Standards No. 48, "Revenue Recognition When
Right of Return Exists".



                                       10
<PAGE>   11

    Maintenance revenue on product sales is allocated and deferred based on
vendor specific objective evidence of fair value, generally established based on
renewal rates. The deferred revenues are then recognized ratably over the term
of the maintenance period.

    Upon shipment of products to its customers, the Company provides for the
estimated cost to repair or replace products that may be returned under
warranty. The Company's warranty period is typically 12 months from the date of
shipment to the end user customer.

    Revenue recognition for software transactions is accounted for pursuant to
the American Institute of Certified Public Accountants' (AICPA) Statement of
Position (SOP) 97-2, "Software Revenue Recognition" as modified by SOP 98-9,
"Modification of SOP 97-2, Software Revenue Recognition, with Respect to Certain
Transactions." SOP 97-2 generally requires revenue earned on software
arrangements involving multiple-elements to be allocated to each element based
on its relative fair value. The fair value of the element must be based on
objective evidence that is specific to the vendor. If a vendor does not have
objective evidence of the fair value of all elements in a multiple-element
arrangement, all revenue from the arrangement must be deferred until such
evidence exists or until all elements have been delivered, unless the only
undelivered element is post-contract customer support, in which case, the entire
fee is recognized over the support period.

    Net revenues increased to $13.1 million in the three months ended June 30,
2001 from $9.1 million in the same quarter in the prior year, an increase of
44%. Net revenues increased to $24.3 million in the six months ended June 30,
2001 from $16.3 million in the same period in the prior year, an increase of
49%. The increases were due primarily to favorable mix in addition to an
increased number of units sold.

    For the three months ended June 30, 2001, sales to Alternative Technology,
Inc. accounted for 20% of net revenues and sales to Allasso accounted for 11% of
net revenues. For the six months ended June 30, 2001, one customer, Alternative
Technology, Inc., accounted for 19% of net revenues. For the same periods in the
prior year, one customer, Alternative Technology, Inc., accounted for 16% and
12% of net revenues, respectively. Sales to the top 10 indirect channel partners
accounted for 56% and 48% of net revenues in the six months ended June 30, 2001
and 2000, respectively.

    COST OF REVENUES

    Our cost of revenues consists primarily of the cost of finished products
purchased from our turnkey manufacturer and overhead costs. We outsource the
manufacturing of our products. Our cost of revenues increased to $3.9 million in
the three months ended June 30, 2001 from $2.9 million for the same quarter in
the prior year, an increase of 38%. Our cost of revenues increased to $7.7
million in the six months ended June 30, 2001 from $5.1 million in the six
months ended June 30, 2000, an increase of 51%. The cost of revenues represented
32% and 31% of net revenues in the six months ended June 30, 2001 and 2000,
respectively. The increase was due primarily to increases in personnel related
and other cost increases in the customer support and manufacturing operations
functions.

    AMORTIZATION OF ACQUIRED TECHNOLOGY

    Amortization of acquired technology relates to the acquired developed
technologies of Workfire Technologies International, Inc. ("Workfire"). The
acquisition occurred in September 2000. The amortization of acquired technology
was $599,000 and $1.2 million in the three and six months periods ended June 30,
2001, respectively. Amortization of acquired technology represented 5% of net
revenues for the three and six months ended June 30, 2001.

    RESEARCH AND DEVELOPMENT

    Research and development expenses consist primarily of salaries and related
personnel expenses, consultant fees and prototype expenses related to the
design, development, testing and enhancement of the PacketShaper, AppVantage and
AppCelera products and PacketWise software. Research and development increased
to $3.0 million in the three months ended June 30, 2001 from $2.0 million in the
same quarter of the prior year, an increase of 52%. For the six months ended
June 30, 2001, research and development expenses of $5.9 million increased $2.2
million, or 58%, from the $3.7 million in the same period in the prior year. The
increases were due to increases in staffing and related personnel costs.
Research and development represented 24% and 23% of net revenues in the six
months ended June 30, 2001 and 2000, respectively. As of June 30, 2001, all
research and development costs have been expensed as incurred. We expect
spending to remain at current dollar levels for the remainder of 2001.

    SALES AND MARKETING



                                       11
<PAGE>   12

    Sales and marketing expenses consist primarily of salaries, commissions and
related personnel expenses for those engaged in the sales and marketing of the
product as well as related trade show, promotional and public relations
expenses. Sales and marketing expenses increased to $5.4 million in the three
months ended June 30, 2001 from $4.3 million in the same quarter of the prior
year, an increase of 27%. Sales and marketing expenses increased to $11.7 in the
six months ended June 30, 2001, up $3.6 million, or 45%, from the $8.1 million
in the first half of the prior year. The increases reflected the hiring of
additional personnel in connection with building our sales force, and channel
and increased marketing activities. Sales and marketing expenses represented 47%
and 50% of net revenues in the six months ended June 30, 2001 and 2000,
respectively. This percentage decrease is primarily a result of increased
revenues. Second quarter sales and marketing expenses of $5.4 million declined
$792,000 from the $6.2 million in the first quarter, primarily reflecting cost
control measures implemented at the end of March 2001 in response to the slowing
economy and resulting slowing of revenues. We intend to continue to invest in
appropriate sales and marketing campaigns and therefore expect our absolute
dollar expenses to increase in the future.

    GENERAL AND ADMINISTRATIVE

    General and administrative expenses consist primarily of salaries and
related personnel expenses for administrative personnel, professional fees and
other general corporate expenses. General and administrative expenses increased
to $1.4 million in the three months ended June 30, 2001 from $1.1 million in the
same quarter of the prior year, an increase of 36%. For the first six months of
2001, general and administrative was $2.9 million, up 26% from the $2.3 million
in the first half of the prior year. General and administrative represented 12%
and 14% of net revenues in the six months ended June 30, 2001 and 2000,
respectively. This percentage decrease was primarily due to increased net
revenues. As we add personnel and incur additional costs related to the growth
of our business, we expect our absolute dollar expenses to increase in the
future.

    STOCK-BASED COMPENSATION

    Stock-based compensation resulted primarily from stock option grants to
employees and options assumed in the Workfire acquisition. Stock-based
compensation is being amortized to expense in accordance with FASB
Interpretation No. 28 over the vesting period of the individual options,
generally four years. We recorded stock-based compensation expense of $340,000
and $342,000 in the three months ended June 30, 2001 and 2000, respectively. For
the six months ended June 30, 2001 and 2000, stock based compensation expense
was $764,000 and $723,000, respectively. As of June 30, 2001, there is $1.0
million remaining to be amortized in future periods.

    AMORTIZATION OF GOODWILL

    Amortization of goodwill relating to our September 2000 acquisition of
Workfire totaled an aggregate of $5.5 million and $11.0 million in the three and
six month periods ended June 30, 2001. In connection with the Workfire
acquisition, we recorded goodwill of approximately $66.1 million, which is being
amortized on a straight-line basis over a three-year period. In addition, we may
have additional acquisitions in future periods that could give rise to the
acquisition of additional goodwill. Beginning January 1, 2002, under the
provisions of SFAS No. 142, "Goodwill and Other Intangible Assets", goodwill,
including goodwill acquired in past business combinations, will be accounted for
using an impairment-only approach.

    OTHER INCOME, NET

    Other income, net consists primarily of interest income from our cash and
investments, net of interest expense related to our line of credit, debt and
capital lease obligations, and other expense. Other income, net decreased to
$773,000 in the three months ended June 30, 2001 from $877,000 in the same
quarter in the prior year, a decrease of 12%, the result of both lower invested
balances and lower yields on invested funds. Other income, net of $1.0 million
for the six-month period ended June 30, 2001 decreased $600,000 from the $1.6
million for the period ended June 30, 2000. This decrease was primarily due to
the $545,000 loss on the disposition of $3.0 million of defaulted Southern
California Edison notes.

    LIQUIDITY AND CAPITAL RESOURCES

    Since inception, we have financed our operations primarily from the sale of
preferred and common stock and other financing activities such as bank credit
against accounts receivable, subordinated debt offerings and capital equipment
leasing. Cash, cash equivalents and investments totaled approximately $59.9
million at June 30, 2001, a decrease of $2.3 million from December 31, 2000. The
decrease primarily reflects payments of liabilities.


                                       12
<PAGE>   13

    We have entered into leases to finance the acquisition of computer software
and hardware, and furniture. At this time, we have fully utilized the $1.5
million capacity of our current lease and intend to enter into another equipment
financing facility in the second half of 2001. As of June 30, 2001,
approximately $2.2 million was outstanding under capital lease obligations
related to lease agreements. We also have a revolving credit facility against
accounts receivable, which provides for borrowings of up to $10.0 million. This
facility expires on January 9, 2002. Borrowings under this credit facility bear
interest at the prime rate, which was 6.75% as of June 30, 2001, are due upon
demand and are secured by substantially all of our assets. At June 30, 2001, we
had borrowed approximately $3.1 million against this credit facility.

    We have used the initial public offering net proceeds of $62.6 million
primarily to repay subordinated loans of $5.0 million and to fund operations,
including expanding and enhancing our sales and marketing operations and product
offerings.

    We expect to experience growth in our working capital needs for the
foreseeable future in order to execute our business plan. We anticipate that
operating activities, as well as planned capital expenditures, will constitute a
partial use of our cash resources. In addition, we may utilize cash resources to
fund acquisitions or investments in complementary businesses, technologies or
products and to finance new facilities related to expansion of our business. We
believe that our current cash, cash equivalents, investments, cash generated
from operations and available borrowings under our credit facilities will be
sufficient to meet our anticipated cash requirements for working capital and
capital expenditures for at least the foreseeable future.

    RECENT ACCOUNTING PRONOUNCEMENTS

    The impact of recent accounting pronouncements is discussed in Note 3 of the
notes to condensed consolidated financial statements.

    FACTORS THAT MAY AFFECT FUTURE RESULTS

    You should carefully consider the risks described below before making an
investment decision. If any of the following risks actually occur, our business,
financial condition or results of operations could be materially and adversely
affected. In such case, the trading price of our common stock could decline, and
you may lose all or part of your investment.

OUR LIMITED OPERATING HISTORY AND THE RAPIDLY EVOLVING MARKET WE SERVE MAKES
EVALUATING OUR BUSINESS PROSPECTS DIFFICULT

    We were incorporated in January 1996 and began shipping our products
commercially in February 1997. Because of our limited operating history and the
uncertain nature of the rapidly changing market that we serve, we believe the
prediction of future results of operations is difficult. As an investor in our
common stock, you should consider the risks and difficulties that we face as an
early stage company in a new and rapidly evolving market. Some of the specific
risks we face include our ability to:

    -   execute our sales and marketing strategy;

    -   maintain current and develop new relationships with key VARs,
        distributors, systems integrators and OEMs; and

    -   expand our domestic and international sales efforts.

WE HAVE A HISTORY OF LOSSES, EXPECT OUR EXPENDITURES TO INCREASE AND OUR LOSSES
TO CONTINUE, AND MAY NEVER ACHIEVE PROFITABILITY

    We have incurred losses since we commenced operations in 1996 and may never
achieve profitability. Furthermore, we currently expect that our operating
expenditures will continue to increase significantly and we may not generate a
sufficient level of revenues to offset these expenditures or be able to adjust
spending in a timely manner to respond to any unanticipated decline in revenues.
We incurred net losses of $9.4, $10.9 and $8.8 million in 2000, 1999 and 1998,
respectively. For the six months ended June 30, 2001, we incurred a net loss of
$15.9 million and as of June 30, 2001 we had an accumulated deficit of $52.1
million. Although our revenues have grown over time, we cannot be certain when
or if we will realize sufficient revenues to achieve profitability. If revenues
grow slower than we anticipate or if operating expenditures exceed our
expectations or cannot be adjusted accordingly, we may continue to experience
significant losses on a quarterly and annual basis. Even if we achieve
profitability, we cannot assure you that we can sustain or increase
profitability on a quarterly or annual basis in the future.

OUR FUTURE OPERATING RESULTS MAY NOT MEET ANALYSTS' EXPECTATIONS AND MAY
FLUCTUATE SIGNIFICANTLY, WHICH COULD ADVERSELY AFFECT OUR STOCK PRICE

    We believe that period-to-period comparisons of our operating results cannot
be relied upon as an indicator of our future performance. Our operating results
may be below the expectations of public market analysts or investors in some
future quarter. If this occurs, the price of our common stock would likely
decrease. Our operating results are likely to fluctuate significantly in the
future on both a quarterly and an annual basis due to a number of factors, many
of which are outside our control. Factors that could cause our operating results
to fluctuate include variations in:

    -   the timing and size of orders and shipments of our products;

    -   the amount and timing of revenues from OEMs;

    -   the mix of products we sell;

    -   the mix of channels through which those products are sold;

    -   the average selling prices of our products; and

    -   the amount and timing of our operating expenses.

    In the past, we have experienced fluctuations in operating results. These
fluctuations resulted primarily from variations in the mix of products sold and
variations in channels through which products were sold and most recently in the
three months ended March 31, 2001, the delay in customer orders and reductions
in our customers' information technology budgets due to recent changes in the
U.S. economy. Research and development expenses have fluctuated due to increased
prototype expenses and consulting fees related to the launch of new products and
increased personnel expenses. Sales and marketing expenses have fluctuated due
to increased personnel expenses, expenditures related to trade shows and the
launch of new products. See "Management's Discussion and Analysis of Financial
Condition and Results of Operations" for detailed information on our operating
results.

OUR RELIANCE ON SALES OF OUR PRODUCTS BY OTHERS MAKES IT DIFFICULT TO PREDICT
OUR REVENUES AND RESULTS OF OPERATIONS

    The timing of our revenues is difficult to predict because of our reliance
on indirect sales channels and the variability of our sales cycle. The length of
our sales cycle for sales through our indirect channel partners to our end users
may vary substantially depending upon the size of the order and the distribution
channel through which our products are sold. We expect to have difficulties in
predicting revenues from OEMs because we are unable to forecast unit sales of
their products that incorporate our technology.

    If revenues forecasted in a particular quarter do not occur in that quarter,
our operating results for that quarter could be adversely affected. Furthermore,
because our expense levels are based on our expectations as to future revenue
and to a large extent are fixed in the short term, a substantial reduction or
delay in sales of our products or the loss of any significant indirect channel
partner could harm our business.

IF THE APPLICATION TRAFFIC AND BANDWIDTH MANAGEMENT SOLUTIONS MARKET FAILS TO
GROW, OUR BUSINESS WILL FAIL

    The market for application bandwidth management solutions is in an early
stage of development and its success is not guaranteed. Therefore, we cannot
accurately assess the size of the market, the products needed to address the
market, the optimal distribution strategy, or the competitive environment that
will develop. In order for us to be successful, our potential customers must
recognize the value of more sophisticated bandwidth management solutions, decide
to invest in the management of their networks and the performance of important
business software applications and, in particular, adopt our bandwidth
management solutions. The growth of the bandwidth management solutions market
also depends upon a number of factors, including the availability of inexpensive
bandwidth, especially in international markets, and the growth of wide area
networks.

IF WE ARE UNABLE TO DEVELOP AND MAINTAIN STRONG PARTNERING RELATIONSHIPS WITH
OUR INDIRECT CHANNEL PARTNERS, OR IF THEIR SALES EFFORTS ON OUR BEHALF ARE NOT
SUCCESSFUL, OUR SALES MAY SUFFER AND OUR REVENUES MAY NOT INCREASE



                                       14
<PAGE>   15

    We rely primarily on an indirect distribution channel consisting of VARs,
distributors, systems integrators and OEMs for all of our revenues. Because many
of our indirect channel partners also sell competitive products, our success and
revenue growth will depend on our ability to develop and maintain strong
cooperative relationships with significant indirect channel partners, as well as
on the sales efforts and success of those indirect channel partners.

    We cannot assure you that our indirect channel partners will market our
products effectively or continue to devote the resources necessary to provide us
with effective sales, marketing and technical support. In order to support and
develop leads for our indirect distribution channels, we plan to expand our
field sales and support staff significantly. We cannot assure you that this
internal expansion will be successfully completed, that the cost of this
expansion will not exceed the revenues generated or that our expanded sales and
support staff will be able to compete successfully against the significantly
more extensive and well-funded sales and marketing operations of many of our
current or potential competitors. In addition, our indirect channel agreements
are generally not exclusive and one or more of our channel partners may compete
directly with another channel partner for the sale of our products in a
particular region or market. This may cause such channel partners to stop or
reduce their efforts in marketing our products. Our inability to effectively
establish or manage our distribution channels would harm our sales.

IF WE ARE NOT ABLE TO MAINTAIN CURRENT AND FUTURE OEM RELATIONSHIPS, OUR
BUSINESS WILL BE HARMED

    We may be unable to retain our current or future OEM partners. Generally,
OEM relationships can be terminated with little or no notice. Our OEM agreements
with ADC Telecommunications, Inc., Adtran, Inc., and Intel Corporation are not
exclusive and the initial terms range from one to five years, with no obligation
to renew their respective agreements with us. We expect to enter into similar
OEM relationships in the future. If our relationship with any current or future
OEM partner is terminated by either party, we may not be successful in replacing
such partner on a timely basis or at all with another suitable OEM partner.

DEVELOPING STRONG OEM RELATIONSHIPS WILL BE TIME AND RESOURCE INTENSIVE AND MAY
NOT RESULT IN THE SUCCESSFUL DEPLOYMENT OF OUR TECHNOLOGY AND PRODUCTS

    One aspect of our sales strategy is to develop relationships with OEM
partners that will license our PacketWise software and incorporate it into their
networking products. If we are not successful in entering into suitable OEM
relationships, our ability to successfully deploy our PacketWise software and
build brand awareness would be harmed. The development of OEM relationships
generally involves a considerable amount of management time and company
resources as potential OEM partners evaluate the viability of integrating our
technology. We cannot assure you that potential OEM partners will enter into a
relationship with us after we have expended these efforts and costs. In
addition, even if we are successful in entering into an OEM relationship, we
cannot assure you that our current or future OEM partners will be able to
integrate our technology into commercially viable products on a timely basis.
Furthermore, we cannot assure you that our OEM partners will give a high
priority to the marketing and sale of products which incorporate our technology
or that our OEM partners will not develop competitive products and decide to
terminate or minimize their relationship with us. The failure to build and
maintain successful OEM relationships would have a negative effect on the
deployment of our technology and products.

OUR RELIANCE ON OEM PARTNERS FOR THE SALE OF OUR PRODUCTS MAKES IT DIFFICULT TO
MANAGE AND FORECAST PRODUCTION AND DELIVERY SCHEDULES AND SALES EXPECTATIONS

    Our inability to forecast the level of orders from OEM partners may make it
difficult to schedule production, manage our contract manufacturers and forecast
sales. The level and timing of orders placed by OEM partners who purchase
hardware from us may vary due to many factors including OEM partners' attempts
to balance their inventories, changes in the OEM partners' manufacturing
strategies and variation in demand for their products. Due to product life
cycles, competitive and economic conditions, these OEM partners generally do not
commit to firm production schedules in advance. Anticipated orders from our
current or future OEM partners may not materialize or delivery schedules may be
deferred as a result of changes in customers' business needs. These order
fluctuations and deferrals will harm our business.

OUR PRODUCT LINES CURRENTLY CONSIST OF THE PACKETSHAPER, APPVANTAGE AND
APPCELERA SYSTEMS AND PACKETWISE SOFTWARE, AND ALL OF OUR CURRENT REVENUES AND A
SIGNIFICANT PORTION OF OUR FUTURE GROWTH DEPENDS ON THEIR COMMERCIAL SUCCESS



                                       15
<PAGE>   16

    All of our current revenues and a significant portion of our future growth
depends on the commercial success of our PacketShaper, AppVantage and AppCelera
lines of products and PacketWise software, which are the only products that we
currently offer. If our target customers do not widely adopt, purchase and
successfully deploy the PacketShaper, AppVantage and AppCelera lines of products
or PacketWise software, our revenues will not grow significantly or at all.

INTRODUCTION OF OUR NEW PRODUCTS MAY CAUSE CUSTOMERS TO DEFER PURCHASES OF OUR
EXISTING PRODUCTS WHICH COULD HARM OUR OPERATING RESULTS

    When we announce new products or product enhancements that have the
potential to replace or shorten the life cycle of our existing products,
customers may defer purchasing our existing products. These actions could harm
our operating results by unexpectedly decreasing sales, increasing our inventory
levels of older products and exposing us to greater risk of product
obsolescence.

MOST OF THE COMPONENTS FOR OUR PRODUCTS COME FROM SINGLE OR LIMITED SOURCES, AND
WE COULD LOSE SALES IF THESE SOURCES FAIL TO SATISFY OUR SUPPLY REQUIREMENTS

    Almost all of the components used in our products are obtained from single
or limited sources. Our products have been designed to incorporate a particular
set of components. As a result, our desire to change the components of our
products or our inability to obtain suitable components on a timely basis would
require engineering changes to our products before we could incorporate
substitute components.

    We do not have any long-term supply contracts to ensure sources of supply.
If our contract manufacturers fail to obtain components in sufficient quantities
when required, our business could be harmed. Our suppliers also sell products to
our competitors. Our suppliers may enter into exclusive arrangements with our
competitors, stop selling their products or components to us at commercially
reasonable prices or refuse to sell their products or components to us at any
price. Our inability to obtain sufficient quantities of sole-sourced or
limited-sourced components, or to develop alternative sources for components or
products would harm our ability to grow our business.

IF OUR INTERNATIONAL SALES EFFORTS ARE UNSUCCESSFUL, OUR BUSINESS WILL FAIL TO
GROW

    The failure of our indirect channel partners to sell our products
internationally will harm our business. Sales to customers outside of North
America accounted for 56% of our net revenues in the six months ended June 30,
2001 and more than half of our net revenues for fiscal 2000 and 1999. In
particular, sales to customers in the Asia Pacific region accounted for 26% our
net revenues in the six months ended June 30, 2001. Our ability to grow will
depend in part on the expansion of international sales, which will require
success on the part of our VARs, distributors, systems integrators and OEMs in
marketing our products.

    We intend to expand operations in our existing international markets and to
enter new international markets, which will demand management attention and
financial commitment. We may not be able to successfully expand our
international operations. In addition, a successful expansion of our
international operations and sales in foreign markets will require us to develop
relationships with suitable indirect channel partners operating abroad. We may
not be able to identify, attract or retain these indirect channel partners.

    Furthermore, to increase revenues in international markets, we will need to
continue to establish foreign operations, to hire additional personnel to run
these operations and to maintain good relations with our foreign indirect
channel partners. To the extent that we are unable to successfully do so, our
growth in international sales will be limited.

    Our international sales are currently all U.S. dollar-denominated. As a
result, an increase in the value of the U.S. dollar relative to foreign
currencies could make our products less competitive in international markets. In
the future, we may elect to invoice some of our international customers in local
currency. Doing so will subject us to fluctuations in exchange rates between the
U.S. dollar and the particular local currency.

SALES TO LARGE CUSTOMERS WOULD BE DIFFICULT TO REPLACE IF LOST

    A limited number of indirect channel partners have accounted for a large
part of our revenues to date and we expect that this trend will continue.
Because our expense levels are based on our expectations as to future revenue
and to a large extent are fixed in the short term, any significant reduction or
delay in sales of our products to any significant indirect channel partner or
unexpected returns from these indirect channel partners could harm our business.
Sales to one customer, Alternative Technology, Inc., accounted for 19% and



                                       16
<PAGE>   17

12% of net revenues in the six months ended June 30, 2001 and fiscal 2000,
respectively. We expect that our largest customers in the future could be
different from our largest customers today. End users can stop purchasing and
indirect channel partners can stop marketing our products at any time. We cannot
assure you that we will retain these indirect channel partners or that we will
be able to obtain additional or replacement partners. The loss of one or more of
our key indirect channel partners or the failure to obtain and ship a number of
large orders each quarter could harm our operating results.

THE MERGER OF WORKFIRE INTO OUR COMPANY COULD ADVERSELY AFFECT OUR COMBINED
FINANCIAL RESULTS

    If the benefits of the merger of Workfire into our company do not exceed the
costs of the merger, including dilution to our stockholders resulting from the
issuance of shares in connection with the merger, our financial results,
including earnings per share, could be adversely affected. We are not certain
that we will be able to achieve our financial estimates if the anticipated
revenue from the sale of products containing technology or other intellectual
property acquired in the merger is not realized. In addition we have recorded
goodwill, intangible assets and deferred stock-based compensation of
approximately $72.8 million in connection with the merger, which is being
amortized over a period of three years from the date of acquisition. In
accordance with Statement of Financial Accounting Standards No. 121, "Accounting
for Impairment of Long-Lived Assets and for Long-Lived Assets to be Disposed Of"
and Statement of Financial Accounting Standards No. 142, "Goodwill and Other
Intangible Assets", when implemented, we plan to review these assets for
impairment whenever events or changes in circumstances indicate that the
carrying amount of the assets may not be recoverable.

THE MARKET PRICE OF OUR COMMON STOCK MAY DECLINE AS A RESULT OF THE MERGER OF
WORKFIRE INTO OUR COMPANY

    The market price of our common stock may decline as a result of the merger
if:

    -   the integration of our company and Workfire is unsuccessful;

    -   we do not achieve the perceived benefits of the merger as rapidly or to
        the extent anticipated by the financial or industry analysts or
        investors; or

    -   the effect of the merger on our financial results is not consistent with
        the expectations of financial or industry analysts or investors.

    The market price of our common stock could also decline as a result of
factors related to the merger, which may currently be unforeseen. A decline in
the market price of our common stock could materially and adversely affect our
operating results.

ANY ACQUISITIONS WE MAKE COULD RESULT IN DILUTION, UNFAVORABLE ACCOUNTING
CHARGES AND DIFFICULTIES IN SUCCESSFULLY MANAGING OUR BUSINESS

    We continually evaluate strategic acquisitions of other businesses. Our
consummation of the acquisition of other businesses would subject us to a number
of risks, including the following:

    -   difficulty in integrating the acquired operations and retaining acquired
        personnel;

    -   limitations on our ability to retain acquired distribution channels and
        customers;

    -   diversion of management's attention and disruption of our ongoing
        business; and

    -   limitations on our ability to successfully incorporate acquired
        technology and rights into our product and service offerings and
        maintain uniform standards, controls, procedures, and policies.

    We may not successfully overcome problems encountered in connection with
potential acquisitions. In addition, acquisitions could harm our operating
results by diluting our stockholders' equity and requiring us to amortize
acquisition expenses and acquired assets. Further, potential acquisitions could
cause us to incur additional debt.


                                       17
<PAGE>   18

THE CARRYING VALUE OF OUR ASSETS COULD BE SUBJECT TO IMPAIRMENT WRITE-DOWNS

    In July 2001, the Financial Accounting Standards Board issued SFAS No. 142,
"Goodwill and Other Intangible Assets", which establishes a new standard of
accounting for goodwill acquired in business combinations, effective January 1,
2002. SFAS No. 142 continues to require recognition of goodwill as an asset, but
does not permit amortization of this goodwill as is currently required. SFAS No.
142 could make our acquisition-related charges less predictable in any given
reporting period. Pursuant to the new statement, goodwill will be separately
tested using a fair-value based approach at least once per year for impairment
or when an event occurs indicating the potential for impairment. If the carrying
value of our goodwill exceeds the fair value, we would be required to report
goodwill impairment charges as an operating expense in the income statement. The
change from an amortization approach to an impairment approach applies to
previously recorded goodwill, as well as goodwill arising from acquisitions
completed after the application of the new standard.

        Effective January 1, 2002, our goodwill amortization charges will cease.
However, it is possible that in the future we may incur larger impairment
charges related to the goodwill already recorded or arising out of future
acquisitions. This policy may subject our future earnings to significant
volatility, particularly on a period-to-period basis. Accordingly, the
impairment of our goodwill or other intangible assets could adversely affect our
operating results.

OUR INABILITY TO ATTRACT AND RETAIN QUALIFIED PERSONNEL COULD SIGNIFICANTLY
INTERRUPT OUR BUSINESS OPERATIONS

    Our future success will depend, to a significant extent, on the ability of
our management to operate effectively, both individually and as a group. Given
our early stage of development, we are dependent on our ability to attract,
retain and motivate high caliber key personnel. We currently have a small
indirect channel partner and end-user service and support organization and will
need to increase our staff to support new indirect channel partners and end
users and the expanding needs of existing indirect channel partners and end
users. Additionally, we rely on qualified systems engineers and service and
support personnel to provide pre and post-sales technical support for our
products. Competition for qualified personnel in the networking industry,
including systems engineers, sales and service and support personnel, is
intense, and we may not be successful in attracting and retaining such
personnel. There may be only a limited number of persons with the requisite
skills to serve in these key positions and it may become increasingly difficult
to hire such persons. Our business will suffer if we encounter delays in hiring
these additional personnel.

    Competitors and others have in the past and may in the future attempt to
recruit our employees. We do not have employment contracts with any of our
personnel. The loss of services of any of our senior management could negatively
impact our ability to carry out our business plan.

WE MAY BE UNABLE TO COMPETE EFFECTIVELY WITH OTHER COMPANIES IN OUR MARKET
SECTOR WHO ARE SUBSTANTIALLY LARGER AND MORE ESTABLISHED AND WHO HAVE
SIGNIFICANTLY GREATER RESOURCES THAN OUR COMPANY

    We compete in a new, rapidly evolving and highly competitive sector of the
networking technology market. We expect competition to persist and intensify in
the future from a number of different sources. Increased competition could
result in reduced prices and gross margins for our products and could require
increased spending by us on research and development, sales and marketing and
customer support, any of which could harm our business. We compete with Cisco
Systems, Inc. and CheckPoint Software Technologies Ltd., which sell products
incorporating competing technologies. We also compete with several small private
companies, which utilize competing technologies to provide bandwidth management.
In addition, our products and technology compete for information technology
budget allocations with products that offer monitoring capabilities, such as
probes and related software. Lastly, we face indirect competition from companies
that offer enterprises and service providers increased bandwidth and
infrastructure upgrades that increase the capacity of their networks, which may
lessen or delay the need for bandwidth management solutions.

    Many of our competitors are substantially larger than we are and have
significantly greater financial, sales and marketing, technical, manufacturing
and other resources and more established distribution channels. These
competitors may be able to respond more rapidly to new or emerging technologies
and changes in customer requirements or devote greater resources to the
development, promotion and sale of their products than we can. We have
encountered, and expect to encounter, customers who are extremely confident in
and committed to the product offerings of our competitors. Furthermore, some of
our competitors may make strategic acquisitions or establish cooperative
relationships among themselves or with third parties to increase their ability
to rapidly gain



                                       18
<PAGE>   19

market share by addressing the needs of our prospective customers. These
competitors may enter our existing or future markets with solutions that may be
less expensive, provide higher performance or additional features or be
introduced earlier than our solutions. Given the market opportunity in the
bandwidth management solutions market, we also expect that other companies may
enter our market with alternative products and technologies, which could reduce
the sales or market acceptance of our products and services, perpetuate intense
price competition or make our products obsolete. If any technology that is
competing with ours is or becomes more reliable, higher performing, less
expensive or has other advantages over our technology, then the demand for our
products and services would decrease, which would harm our business.

IF WE DO NOT EXPAND OR ENHANCE OUR PRODUCT OFFERINGS OR RESPOND EFFECTIVELY TO
TECHNOLOGICAL CHANGE, OUR BUSINESS MAY NOT GROW

    Our future performance will depend on the successful development,
introduction and market acceptance of new and enhanced products that address
customer requirements in a cost-effective manner. We cannot assure you that our
technological approach will achieve broad market acceptance or that other
technologies or solutions will not supplant our approach. The bandwidth
management solutions market is characterized by rapid technological change,
frequent new product introductions, changes in customer requirements and
evolving industry standards. The introduction of new products, market acceptance
of products based on new or alternative technologies, or the emergence of new
industry standards, could render our existing products obsolete or make it
easier for other products to compete with our products. Developments in
router-based queuing schemes could also significantly reduce demand for our
products. Alternative technologies, including packet-queuing technology, could
achieve widespread market acceptance. Our future success will depend in large
part upon our ability to:

    -   develop and maintain competitive products;

    -   enhance our products by adding innovative features that differentiate
        our products from those of our competitors;

    -   bring products to market on a timely basis at competitive prices;

    -   identify and respond to emerging technological trends in the market; and

    -   respond effectively to new technological changes or new product
        announcements by others.

    We have in the past experienced delays in product development which to date
have not materially adversely affected us. However, these delays may occur in
the future and could result in a loss of customers and market share.

IF WE ARE UNABLE TO EFFECTIVELY MANAGE OUR GROWTH, WE MAY EXPERIENCE OPERATING
INEFFICIENCIES AND HAVE DIFFICULTY MEETING DEMAND FOR OUR PRODUCTS

    We have rapidly and significantly expanded our operations and anticipate
that further significant expansion will be required to address potential growth
in our customer base and market opportunities. This expansion could place a
significant strain on our management, products and support operations, sales and
marketing personnel and other resources, which could harm our business.

    In the future, we may experience difficulties meeting the demand for our
products and services. The installation and use of our products requires
training. If we are unable to provide training and support for our products, the
implementation process will be longer and customer satisfaction may be lower. In
addition, our management team may not be able to achieve the rapid execution
necessary to fully exploit the market for our products and services. We cannot
assure you that our systems, procedures or controls will be adequate to support
the anticipated growth in our operations.

    We may not be able to install management information and control systems in
an efficient and timely manner, and our current or planned personnel, systems,
procedures and controls may not be adequate to support our future operations.

THE AVERAGE SELLING PRICES OF OUR PRODUCTS COULD DECREASE RAPIDLY WHICH MAY
NEGATIVELY IMPACT GROSS MARGINS AND REVENUES

    We may experience substantial period-to-period fluctuations in future
operating results due to the erosion of our average selling prices. The average
selling prices of our products could decrease in the future in response to
competitive pricing pressures, increased sales discounts, new product
introductions by us or our competitors or other factors. Therefore, to maintain
our gross margins, we



                                       19
<PAGE>   20

must develop and introduce on a timely basis new products and product
enhancements and continually reduce our product costs. Our failure to do so
would cause our revenue and gross margins to decline.

OUR RELIANCE ON SMTC FOR ALL OF OUR MANUFACTURING REQUIREMENTS COULD CAUSE US TO
LOSE ORDERS IF THIS THIRD PARTY MANUFACTURER FAILS TO SATISFY OUR COST, QUALITY
AND DELIVERY REQUIREMENTS

    We currently contract with SMTC Corporation, for the manufacture of all of
our current products. Any manufacturing disruption could impair our ability to
fulfill orders. Our future success will depend, in significant part, on our
ability to have others manufacture our products cost-effectively and in
sufficient volumes. We face a number of risks associated with our dependence on
third-party manufacturers including:

    -   reduced control over delivery schedules;

    -   the potential lack of adequate capacity during periods of excess demand;

    -   manufacturing yields and costs;

    -   quality assurance; and

    -   increases in prices and the potential misappropriation of our
        intellectual property.

    We have no long-term contracts or arrangements with any of our vendors that
guarantee product availability, the continuation of particular payment terms or
the extension of credit limits. We have experienced in the past, and may
experience in the future, problems with our contract manufacturer, such as
inferior quality, insufficient quantities and late delivery of product. To date,
these problems have not materially adversely affected us. We may not be able to
obtain additional volume purchase or manufacturing arrangements on terms that we
consider acceptable, if at all. If we enter into a high-volume or long-term
supply arrangement and subsequently decide that we cannot use the products or
services provided for in the agreement, our business will be harmed. We cannot
assure you that we can effectively manage our contract manufacturer or that this
manufacturer will meet our future requirements for timely delivery of products
of sufficient quality or quantity. Any of these difficulties could harm our
relationships with customers and cause us to lose orders.

    In the future, we may seek to use additional contract manufacturers. We may
experience difficulty in locating and qualifying suitable manufacturing
candidates capable of satisfying our product specifications or quantity
requirements. Further, new third-party manufacturers may encounter difficulties
in the manufacture of our products resulting in product delivery delays.

OUR PRODUCTS MAY HAVE ERRORS OR DEFECTS THAT WE FIND AFTER THE PRODUCTS HAVE
BEEN SOLD, WHICH COULD NEGATIVELY AFFECT OUR REVENUES, THE MARKET ACCEPTANCE OF
OUR PRODUCTS AND INCREASE OUR COSTS

    Our products are complex and may contain undetected defects, errors or
failures in either the hardware or software. In addition, because our products
plug into our end users' existing networks between the WAN access router and the
enterprise local area network, or LAN, they can directly affect the
functionality of the network. We have in the past encountered errors in our
products, which in a few instances resulted in complete network failures. To
date, these errors have not materially adversely affected us. Additional errors
may occur in our products in the future. The occurrence of defects, errors or
failures could result in the failure of our customer's network or
mission-critical applications, delays in installation, product returns and other
losses to us or to our customers or end users. In addition, we would have
limited experience responding to new problems that could arise with any new
products that we introduce. These occurrences could also result in the loss of
or delay in market acceptance of our products, which could harm our business.

    We may also be subject to liability claims for damages related to product
errors. While we carry insurance policies covering this type of liability, these
policies may not provide sufficient protection should a claim be asserted. A
material product liability claim may harm our business.

FAILURE TO ADEQUATELY PROTECT OUR INTELLECTUAL PROPERTY WOULD RESULT IN
SIGNIFICANT HARM TO OUR BUSINESS



                                       20
<PAGE>   21

    Our success depends significantly upon our proprietary technology and our
failure or inability to protect our proprietary technology would result in
significant harm to our business. We rely on a combination of patent, copyright
and trademark laws, and on trade secrets and confidentiality provisions and
other contractual provisions to protect our proprietary rights. These measures
afford only limited protection. We currently have six issued U.S. patents and
fourteen pending patent applications. Our means of protecting our proprietary
rights in the U.S. or abroad may not be adequate and competitors may
independently develop similar technologies. Our future success will depend in
part on our ability to protect our proprietary rights and the technologies used
in our principal products. Despite our efforts to protect our proprietary rights
and technologies unauthorized parties may attempt to copy aspects of our
products or to obtain and use trade secrets or other information that we regard
as proprietary. Legal proceedings to enforce our intellectual property rights
could be burdensome and expensive and could involve a high degree of
uncertainty. These legal proceedings may also divert management's attention from
growing our business. In addition, the laws of some foreign countries do not
protect our proprietary rights as fully as do the laws of the U.S. Issued
patents may not preserve our proprietary position. If we do not enforce and
protect our intellectual property, our business will suffer substantial harm.

CLAIMS BY OTHERS THAT WE INFRINGE ON THEIR INTELLECTUAL PROPERTY RIGHTS COULD BE
COSTLY TO DEFEND AND COULD HARM OUR BUSINESS

    We may be subject to claims by others that our products infringe on their
intellectual property rights. These claims, whether or not valid, could require
us to spend significant sums in litigation, pay damages, delay product
shipments, reengineer our products or acquire licenses to such third-party
intellectual property. We may not be able to secure any required licenses on
commercially reasonable terms, or at all. We expect that we will increasingly be
subject to infringement claims as the number of products and competitors in the
bandwidth management solutions market grows and the functionality of products
overlaps. Any of these claims or resulting events could harm our business.

IF OUR PRODUCTS DO NOT COMPLY WITH EVOLVING INDUSTRY STANDARDS AND GOVERNMENT
REGULATIONS, OUR BUSINESS COULD BE HARMED

    The market for bandwidth management solutions is characterized by the need
to support industry standards as these different standards emerge, evolve and
achieve acceptance. In the United States, our products must comply with various
regulations and standards defined by the Federal Communications Commission and
Underwriters Laboratories. Internationally, products that we develop may be
required to comply with standards established by telecommunications authorities
in various countries as well as with recommendations of the International
Telecommunication Union. To remain competitive we must continue to introduce new
products and product enhancements that meet these emerging U.S. and
international standards. However, in the future we may not be able to
effectively address the compatibility and interoperability issues that arise as
a result of technological changes and evolving industry standards. Failure to
comply with existing or evolving industry standards or to obtain timely domestic
or foreign regulatory approvals or certificates could harm our business.

OUR GROWTH AND OPERATING RESULTS WOULD BE IMPAIRED IF WE ARE UNABLE TO MEET OUR
FUTURE CAPITAL REQUIREMENTS

    We currently anticipate that our existing cash and investment balances and
available borrowings under our credit facilities will be sufficient to meet our
liquidity needs for the foreseeable future. However, we may need to raise
additional funds in order for us to respond to unforeseen technological or
marketing hurdles or to take advantage of unanticipated opportunities or if our
estimates of revenues, working capital or capital expenditure requirements
change or prove inaccurate.

    In addition, we expect to review potential acquisitions that would
complement our existing product offerings or enhance our technical capabilities.
While we have no current agreements or negotiations underway with respect to any
such acquisition, any future transaction of this nature could require
potentially significant amounts of capital. These funds may not be available at
the time or times needed, or available on terms acceptable to us. If adequate
funds are not available, or are not available on acceptable terms, we may not be
able to take advantage of market opportunities to develop new products or to
otherwise respond to competitive pressures.

CERTAIN PROVISIONS OF OUR CHARTER AND OF DELAWARE LAW MAKE A TAKEOVER OF
PACKETEER MORE DIFFICULT, WHICH COULD LOWER THE MARKET PRICE OF THE COMMON STOCK

    Our corporate documents and Section 203 of the Delaware General Corporation
Law could discourage, delay or prevent a third party or a significant
stockholder from acquiring control of Packeteer. In addition, provisions of our
certificate of incorporation may have the effect of discouraging, delaying or
preventing a merger, tender offer or proxy contest involving Packeteer. Any of
these anti-



                                       21
<PAGE>   22

takeover provisions could lower the market price of the common stock
and could deprive our stockholders of the opportunity to receive a premium for
their common stock that they might otherwise receive from the sale of Packeteer.

    POWER OUTAGES IN CALIFORNIA MAY ADVERSELY AFFECT US

    We have significant operations, including our headquarters, contract
manufacturer and order fulfillment vendor in the state of California and are
dependent on a continuous power supply. California's current energy crisis could
substantially disrupt our operations and increase our expenses. California's
power suppliers have recently implemented, and may in the future continue to
implement, rolling blackouts throughout the state. If blackouts interrupt our
power supply, we may be temporarily unable to continue operations at our
California facilities. Any such interruption in our ability to continue
operations at our facilities could delay the development and delivery of our
products and services and otherwise disrupt communications with our customers or
other third parties on whom we rely. Future interruptions could damage our
reputation and could result in lost revenue, either of which could substantially
harm our business and results of operations. Furthermore, shortages in wholesale
electricity supplies have caused power prices to increase. If energy prices
continue to increase, our operating expenses will likely increase which could
have a negative effect on our operating results.

ITEM 3. QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISKS

    Fixed Income Investments

    Our exposure to market risks for changes in interest rates and principal
relates primarily to investments in debt securities issued by U.S. government
agencies and corporate debt securities. Our general policy is to limit the risk
of principal loss and ensure the safety of invested funds by limiting credit and
market risk. Specifically, we place our investments with issuers we believe to
be of high quality and, by policy, limit the amount of the credit exposure to
any one issuer and limit market risk by limiting duration of any single
investment at 3 years. The Company does not use derivative financial instruments
in its investment portfolio.

    All highly liquid investments with less than three months to maturity from
date of purchase are considered to be cash equivalents; investments with
maturities between three and twelve months are considered to be short-term
investments; and investments with maturities in excess of twelve months are
considered to be long-term investments. We do not expect any material loss with
respect to our investment portfolio. The following table presents the amounts of
cash equivalents and investments that are subject to market risk by range of
expected maturity and weighted average interest rates.

    Foreign Exchange

    We develop products in the United States and sell in North America, Asia,
Europe and other parts of the world. As a result, our financial results could be
affected by factors such as changes in foreign currency, exchange rates or weak
economic conditions in foreign markets. All sales are currently made in U.S.
dollars; and, a strengthening of the dollar could make our products less
competitive in foreign markets. We have no foreign exchange contracts, option
contracts or other foreign hedging arrangements.

Item 2. Changes in Securities and Use of Proceeds

        (d) Use of Proceeds from Sales of Registered Securities. Packeteer
commenced its initial public offering ("IPO") on July 28, 1999 pursuant to a
Registration Statement on Form S-1 (File No. 333-79077). In the IPO, Packeteer
sold an aggregate of 4.6 million shares of common stock (including an over
allotment option of 600,000 shares) at $15.00 per share.

        The sale of the shares of common stock generated aggregate gross
proceeds of approximately $69.0 million. The aggregate net proceeds were
approximately $62.6 million, after deducting underwriting discounts and
commissions of approximately $4.8 million and expenses of the offering of
approximately $1.6 million. Of the net proceeds, Packeteer has used $5.0 million
to repay two separate notes payable of $2.5 million each and has used $1.8
million for transaction costs in connection with the acquisition of Workfire.
The remaining $55.1 million of the net proceeds are expected to be used for
general corporate purposes, including working capital, product development and
capital expenditures. The amounts actually expended for such purposes may vary
significantly and will depend on a number of factors described under "Factors
That May Affect Future Results". A portion of the net proceeds may also be used
to acquire or invest in complementary businesses or products or to obtain the
right to use complementary technologies, however, Packeteer has no agreements or
commitments with respect to any such acquisition or investments and we are not
currently engaged in any material negotiations with respect to any such
transaction. Pending such uses, the net proceeds of the IPO have been invested
in short and long-term, interest bearing, investment grade securities. None of
Packeteer's net proceeds of the IPO were paid directly or indirectly to any
director, officer, general partner of the Company or their associates, persons
owning 10% or more of any class of equity securities of Packeteer, or an
affiliate of Packeteer.
