                   NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
                                   (UNAUDITED)

1.       UNAUDITED INTERIM FINANCIAL INFORMATION

         Business - VINA Technologies, Inc. (the Company), incorporated in June
1996, designs, develops, markets and sells multiservice broadband access
communications equipment that enables communications service providers to
deliver bundled voice and data services. The Company has incurred significant
losses since inception and expects that net losses and negative cash flows from
operations will continue for the foreseeable future.

         Basis of Presentation - The consolidated financial statements include
the accounts of VINA Technologies, Inc. and its wholly-owned subsidiary in the
United Kingdom. All significant intercompany accounts and transactions have been
eliminated in consolidation. The interim accompanying financial information is
unaudited and has been prepared in accordance with generally accepted accounting
principles for interim financial information and with the instructions to Form
10-Q and Article 10 of Regulation S-X. Accordingly, they do not include all of
the information and notes required by generally accepted accounting principles
for annual financial statements. In the opinion of management, such unaudited
information includes all adjustments (consisting only of normal recurring
adjustments) necessary for a fair presentation of the interim information.
Operating results for the nine months ended September 30, 2000 are not
necessarily indicative of the results that may be expected for the year ending
December 31, 2000. For further information, refer to the annual consolidated
financial statements and notes thereto included in the Company's Registration
Statement No. 333-36398 on Form S-1.

         Completion of Initial public offering - In August 2000 the Company
completed its initial public offering. The Company issued 3.45 million shares of
common stock in exchange for net proceeds of approximately $36.5 million. Upon
completion of the initial public offering, all of the Company's outstanding
convertible preferred stock automatically converted into 17.7 million shares of
common stock.

         Comprehensive Loss - Comprehensive loss for the three and nine months
ended September 30, 1999 was the same as net loss. Comprehensive loss for the
three and nine months ended September 30, 2000 was $12,730,000 and $32,188,000
respectively, and includes net loss for the respective periods as well as
$288,000 of unrealized loss on available for sale investments.

         New Accounting Standard - In June 1998, the Financial Accounting
Standards Board issued Statement of Financial Accounting Standard (SFAS) No.
133, "Accounting for Derivative Instruments and Hedging Activities." This
statement requires companies to record derivatives on the balance sheet as
assets or liabilities, measured at fair value. Gains or losses resulting from
changes in the values of those derivatives would be accounted for depending on
the use of the derivative and whether it qualifies for hedge accounting. SFAS
No. 133, as amended, will be effective for the Company beginning in the first
quarter of fiscal year 2001. Although the Company has not fully assessed the
implications of SFAS No. 133, management does not believe adoption of this
statement will have a material impact on the Company's consolidated financial
position, results of operations or cash flows.

         During all periods presented, the Company had securities outstanding
which could potentially dilute basic earnings per share in the future, but were
excluded in the computation of diluted EPS in such periods, as their effect
would have been antidilutive due to the net loss reported in such periods.


4.       SUBSEQUENT EVENT

         On October 30, 2000, the Company entered into a definitive merger
agreement to acquire Woodwind Communications Systems, Inc. ("Woodwind"), a
provider of voice-over-broadband network edge access solutions. Under the terms
of the agreement, the Company will acquire Woodwind for 4,950,000 shares
(subject to adjustment under certain circumstances) of the Company's common
stock, including Woodwind stock options assumed by the Company. The transaction
will be accounted for as a purchase.

expected to occur prior to March 31, 2001.

OVERVIEW

         VINA Technologies is a leading developer of multiservice broadband
access communications equipment that enables communications service providers to
deliver bundled voice and data services. Our products integrate various
broadband access technologies, including existing circuit-based and emerging
packet-based networks, onto a single platform to alleviate capacity constraints
in communications networks.

         From our inception in June 1996 through February 1997, our operating
activities related primarily to developing and testing prototype products,
commencing the staffing of our sales and customer service organizations and
establishing relationships with our customers. We began shipments of our
Multiservice T1 Integrator product family in March 1997. In May 1999, we began
shipping our Multiservice Xchange product. Since inception, we have incurred
significant losses, and as of September 30, 2000, we had an accumulated deficit
of $62.1 million.

         We market and sell our products directly to communications service
providers and through OEM customers and value-added resellers, or VARs. Our
revenue is recognized when persuasive evidence of an arrangement exists,
delivery has occurred or services have been rendered, the price is fixed and
determinable, and collectibility is reasonably assured. This generally occurs
upon commercial shipment of our products at which time we have no further
performance obligations to our customers. We also record a provision at the time
we recognize revenue primarily for warranty costs. No revenue is recognized on
products shipped on a trial basis. We recognize extended warranty and other
service revenue ratably over the respective service periods. This service
revenue has not been significant to date.

         Our customer base is highly concentrated. A relatively small number of
customers have accounted for a significant portion of our historical net
revenue. For the nine months ended September 30, 2000, sales to our five largest
customers accounted for approximately 77% of our net revenue, of which sales to
Lucent Technologies and Gabriel Communications accounted for 37% and 17%,
respectively, of our net revenue. While the level of sales to any specific
customer is anticipated to vary from period to period, we expect that we will
continue to experience significant customer concentration for the foreseeable
future. To date, international sales have not been significant. International
sales have been denominated solely in U.S. dollars and, accordingly, we have not
been exposed to significant fluctuations in foreign currency exchange rates.

         Cost of revenue consists primarily of costs of products manufactured by
a third-party contract manufacturer, component costs, depreciation of property
and equipment, personnel related costs to manage the contract manufacturer and
warranty costs, and excludes amortization of deferred stock compensation. We
conduct program management, manufacturing engineering, quality assurance and
documentation control at our facility in Newark, California. We outsource our
manufacturing and testing requirements to Flextronics International Ltd.
Accordingly, a significant portion of our cost of revenue consists of payments
to this contract manufacturer.

         We expect our gross margin to be affected by many factors, including
competitive pricing pressures, fluctuations in manufacturing volumes, costs of
components and sub-assemblies, costs from our contract manufacturers and the mix
of products or system configurations sold. Additionally, our gross margin may
fluctuate due to changes in our mix of distribution channels. Currently, we
derive a significant portion of our revenue from sales made to our OEM
customers. A significant increase in revenue to these OEM customers would
adversely impact or reduce our gross margin.

         Research and development expenses consist primarily of personnel and
related costs, consulting expenses and prototype costs related to the design,
development, testing and enhancement of our multiservice broadband access
products, and excludes amortization of deferred stock compensation. We expense
all of our research and development expenses as incurred.


                                       9
<PAGE>   10
         Selling, general and administrative expenses consist primarily of
personnel and related costs, including salaries and commissions for personnel
engaged in direct and indirect selling and marketing and other administrative
functions and promotional costs, including advertising, trade shows and related
costs, and excludes amortization of deferred stock compensation.

         From inception through September 30, 2000, we recorded an aggregate of
$56.6 million in deferred stock compensation. This amount represents the
difference between the deemed fair market value of our common stock at the time
of option grants during these periods and the exercise prices of these options.
As there was no public market for our common stock until completion of our
initial public offering in August 2000, the fair market value of our common
stock on option grant dates had been determined by our board of directors. The
board of directors in their determination of fair market value took into
consideration many factors including, but not limited to, our financial
performance, current economic trends, actions by competitors, market maturity,
emerging technologies, near-term backlog and, in some circumstances, valuation
analyses performed by independent appraisers using generally accepted valuation
methodologies such as the income and market approaches. We are amortizing
deferred stock compensation using a multiple option award valuation approach
over the vesting periods of the applicable options, which is generally four
years. The amortization of deferred stock compensation, based upon options
granted through September 30, 2000, is expected to be $7.2 million in the last
quarter of 2000, $17.8 million in 2001, $7.6 million in 2002 and $1.2 million in
2003.

         Interest income, net, consists primarily of interest earned on our
cash, cash equivalent and short-term investment balances partially offset by
interest expense associated with our debt obligations.

RESULTS OF OPERATIONS

         Net revenue. Net revenue increased to $21.2 million for the nine months
ended September 30, 2000 from $8.7 million for the nine months ended September
30, 1999. Net revenue increased to $9.2 million for the quarter ended September
30, 2000 from $3.0 million for the quarter ended September 30, 1999. The
increase in net revenue was primarily attributable to sales of our Multiservice
Xchange products introduced in the second quarter of 1999 and increased unit
sales of our other products, offset by price reductions effected in the second
quarter of 1999.

         Cost of revenue. Cost of revenue increased to $12.9 million for the
nine months ended September 30, 2000 from $5.0 million for the nine months ended
September 30, 1999. Cost of revenue increased to $5.5 million for the quarter
ended September 30, 2000 from $2.2 million from the quarter ended September 30,
1999. Gross profit increased to $8.3 million for the nine months ended September
30, 2000 from $3.7 million for the nine months ended September 30, 1999. Gross
profit increased to $ 3.7 million for quarter ended September 30, 2000 from $0.8
million for the quarter ended September 30, 1999. Gross margin as a percent of
net revenue decreased to 39.1% for the nine months ended September 30, 2000 from
42.8% for the nine months ended September 30, 1999. This decrease was due
primarily to price reductions effected in the second quarter of 1999. Gross
margin as a percent of net revenue increased to 40.6% for the quarter ended
September 30, 2000 from 27.2% for the quarter ended September 30, 1999. This
increase in gross margin as a percent of net revenue was due primarily to higher
net revenue and cost reductions.

<PAGE>   11
         Research and development expenses. Research and development expenses
increased to $8.6 million for the nine months ended September 30, 2000, from
$4.3 million for the nine months ended September 30, 1999. Research and
development expenses increased to $3.4 million for the quarter ended September
30, 2000 from $1.5 million for the quarter ended September 30, 1999. Research
and development expenses as a percentage of net revenue decreased from 49.5% in
the first nine months of 1999 to 40.7% in the first nine months of 2000, as our
revenue increased at a faster rate than research and development expenses.
Research and development expenses as a percentage of net revenue decreased from
51.2% in the quarter ended September 30, 1999 to 37.3% in the quarter ended
September 30, 2000, as our revenue increased at a faster rate than research and
development expenses. The increases in absolute dollar amounts were primarily a
result of additional personnel costs, prototype expenses and consulting costs.
We believe that continued investment in research and development is critical to
attaining our strategic product and cost reduction objectives, and as a result,
we expect these research and development expenses to increase in absolute
dollars in the future.

         Selling, general and administrative expenses. Selling, general and
administrative expenses increased to $14.7 million for the nine months ended
September 30, 2000 from $7.4 million for the nine months ended September 30,
1999. Selling, general and administrative expenses increased to $6.2 million for
the quarter ended September 30, 2000 from $2.8 million for the quarter ended
September 30, 1999. These increases were primarily attributable to increased
personnel costs, including hiring of additional sales and key management
personnel, as well as increased recruiting costs. Selling, general and
administrative expenses as a percentage of net revenue decreased from 84.8% in
the first nine months of 1999 to 69.3% in the first nine months of 2000, and
selling, general and administrative expenses as a percentage of net revenue
decreased from 94.6% in the quarter ended September 30, 1999 to 67.1% in the
quarter ended September 30, 2000, as our revenue in the most recent periods
increased at a faster rate than selling, general and administrative expenses. We
intend to actively participate in marketing, business development activities and
selling and promotional programs, and therefore we expect expenses related to
these programs to continue to increase substantially in absolute dollars in the
future. In addition, we expect to expand our field sales operations and customer
support organizations, which would also result in an increase in selling and
marketing expenses. We expect selling, general and administrative expenses to
continue to increase in absolute dollars in the future.

         Amortization of deferred stock compensation. Amortization of deferred
stock compensation increased to $17.8 million for the nine months ended
September 30, 2000 from $2.1 million for the nine months ended September 30,
1999. Amortization of deferred stock compensation increased to $7.1 million for
the quarter ended September 30, 2000 from $1.5 million for the quarter ended
September 30, 1999. Based on stock options granted through September 30, 2000,
we expect to record $7.2 million of amortization of stock-based compensation in
the three months ending December 31, 2000.

         Interest income, net. Interest income, net for the nine months ended
September 30, 2000 increased to $881,000 from $218,000 for the nine months ended
September 30, 1999. Interest income, net for the quarter ended September 30,
2000 increased to $485,000 from $50,000 for the quarter ended September 30,
1999. These increases were primarily attributable to interest earned on higher
average cash balances throughout the relevant period.

LIQUIDITY AND CAPITAL RESOURCES

         Since inception, we have satisfied our cash requirements primarily
through private sales of convertible preferred stock which generated gross
proceeds of approximately $48.8 million prior to our initial public offering. In
August 2000, we completed an initial public offering of 3,450,000 shares of
Common Stock at a price of $12.00 per share, resulting in proceeds of
approximately $36.5 million net of underwriters discount and offering expenses.
At September 30, 2000, we had cash, cash equivalents and short-term investments
of $50.8 million.

         Net cash used in operating activities for the nine months ended
September 30, 2000 was $11.4 million and $5.3 million for the nine months ended
September 30, 1999. Cash used in operating activities resulted primarily from
net losses from operations offset by amortization of deferred compensation in
each period.

         Net cash used in investing activities was $46.9 million for the nine
months ended September 30, 2000 and net cash provided by investing activities
was $0.6 million for the nine months ended September 30, 1999, in each case
primarily reflecting purchases of short-term investments.

         Cash provided by financing activities for the nine months ended
September 30, 2000 was $62.6 million, which was due primarily to proceeds from
our initial public offering in August 2000. Cash provided by financing
activities for the nine months ended September 30, 1999 was $1.2 million, which
was due primarily to the issuance of long-term debt and exercise of stock
options in 1999.

         We currently have no significant commitments for capital expenditures.
We anticipate that we will increase our capital expenditures consistently with
our anticipated growth in personnel and infrastructure, including facilities and
systems.

         We expect to experience significant growth in our operating expenses
for the foreseeable future. As a result, we anticipate that operating expenses
will constitute a material use of our cash resources. In addition, we may use
cash resources to fund acquisitions or investments in complementary businesses,
technologies or products. We believe that our cash on hand will be sufficient to
meet our working capital and capital expenditure requirements for at least the
next 12 months.

FACTORS THAT MAY AFFECT RESULTS

        The risks and uncertainties described below are not the only ones facing
our Company. Additional risks and uncertainties not presently known to us or
that we currently deem immaterial may also impair our business operations. If
any of the following risks actually occur, our business, financial condition and
results of operations could be materially and adversely affected.

                          RISKS RELATED TO OUR BUSINESS

BECAUSE WE HAVE A LIMITED OPERATING HISTORY AND OPERATE IN A NEW AND RAPIDLY
EVOLVING TELECOMMUNICATIONS MARKET, YOU MAY HAVE DIFFICULTY ASSESSING OUR
BUSINESS AND PREDICTING OUR FUTURE FINANCIAL RESULTS.


                                       12

<PAGE>   13
         We were incorporated in June 1996 and did not begin shipping our
products until March 1997. Due to our limited operating history, it is difficult
or impossible for us to predict our future results of operations.

WE HAVE A HISTORY OF LOSSES, WE EXPECT FUTURE LOSSES, AND WE MAY NOT BE ABLE TO
GENERATE SUFFICIENT NET REVENUE IN THE FUTURE TO ACHIEVE OR SUSTAIN
PROFITABILITY.

         We have incurred significant losses since inception and expect that our
net losses and negative cash flow from operations will continue for the
foreseeable future. We incurred net losses of approximately $4.3 million in
1997, $8.0 million in 1998, $17.1 million in 1999 and $ 31.9 million for the
nine months ended September 30, 2000. As of September 30, 2000, we had an
accumulated deficit of approximately $62.1 million. To achieve profitability, we
will need to generate and sustain substantially higher revenue while maintaining
reasonable cost and expense levels. We have large fixed expenses and expect to
continue to incur significant and increasing expenses for research and
development, sales and marketing, customer support, developing direct sales and
distribution channels, and general and administrative expenses.

WE RELY ON A SMALL NUMBER OF TELECOMMUNICATIONS CUSTOMERS FOR SUBSTANTIAL
PORTIONS OF OUR NET REVENUES. IF WE LOSE ONE OF OUR CUSTOMERS OR EXPERIENCE A
DELAY OR CANCELLATION OF A SIGNIFICANT ORDER OR A DECREASE IN THE LEVEL OF
PURCHASES FROM ANY OF OUR CUSTOMERS, OUR NET REVENUE COULD DECLINE AND OUR
OPERATING RESULTS AND BUSINESS COULD BE HARMED.

         We derive almost all of our net revenue from direct sales to a small
number of telecommunications customers and our indirect sales through our major
original equipment manufacturer, or OEM, customers that sell and market our
products. If we lose one of our customers or experience a delay or cancellation
of a significant order or a decrease in the level of purchases from any of our
customers, our net revenue could decline and our operating results and business
could be harmed. Sales through our most significant OEM customer, Lucent
Technologies, accounted for approximately 46% of our net revenue for the year
ended December 31, 1999 and approximately 37% of our net revenue for the nine
months ended September 30, 2000. Our five largest customers, including Lucent,
accounted for approximately 80% of our net revenue in 1999 and approximately 77%
for the nine months ended September 30, 2000. Sales to Lucent and Gabriel
Communications accounted for 37% and 17%, respectively, of our net revenue for
the nine months ended September 30, 2000. We expect that the telecommunications
industry will continue to experience consolidation. If any of our customers is
acquired by a company that is one of our competitors' customers, we may lose its
business. In addition, if one of our OEM customers is acquired, we could lose
that customer. For example, PairGain, one of our OEM customers, was recently
acquired by ADC Telecommunications, and Intermedia Communications, one of our
service provider customers, was recently acquired by MCI Worldcom. Also, the
ultimate business success of our direct service provider customers, our OEM
customers and value-added resellers, or VARs, and our indirect customers who
purchase our products through OEM customers and VARs, could affect the demand
for our products. In addition, any difficulty in collecting amounts due from one
or more of our key customers could harm our operating results and financial
condition. If any of these events occur, our net revenue could decline and our
operating results and business could be harmed.

OUR NET REVENUE COULD DECLINE SIGNIFICANTLY IF OUR RELATIONSHIPS WITH OUR MAJOR
OEM CUSTOMERS DETERIORATE.


                                       13
<PAGE>   14
         A significant portion of our net revenue is derived from sales to our
major OEM customers. Our agreements with our OEM customers are not exclusive and
do not contain minimum volume commitments. Our OEM agreement with Lucent expires
in May 2002. Lucent may terminate the agreement earlier upon 60 days' notice. At
any time or after a short period of notice, our OEM customers could elect to
cease marketing and selling our products. They may so elect for a number of
reasons, including the acquisition by an OEM customer of one or more of our
competitors or their technologies, or because one or more of our competitors
introduces superior or more cost-effective products. In addition, we intend to
develop and market new products that may compete directly with the products of
our OEM customers, which may also harm our relationships with these customers.
Our existing relationships with our OEM customers could make it harder for us to
establish similar relationships with our OEM customers' competitors. Any loss,
reduction, delay or cancellation in expected sales to any of our OEM customers,
or our inability to establish similar relationships with new OEM customers in
the future, would hurt our business and our ability to increase revenues and
could cause our quarterly results to fluctuate significantly.

THE TELECOMMUNICATIONS INDUSTRY IS CHARACTERIZED BY RAPIDLY CHANGING
TECHNOLOGIES. IF WE ARE UNABLE TO DEVELOP AND MAINTAIN STRATEGIC RELATIONSHIPS
WITH VENDORS OF EMERGING TECHNOLOGIES, WE MAY NOT BE ABLE TO MEET THE CHANGING
NEEDS OF OUR CUSTOMERS.

         Our success will depend on our ability to develop and maintain
strategic relationships with vendors of emerging technologies such as Copper
Mountain, Jetstream and Tachion. We depend on these relationships for access to
information on technical developments and specifications that we need to develop
our products. We also may not be able to predict which existing or potential
partners will develop leading technologies or industry standards. We may not be
able to maintain or develop strategic relationships or replace strategic
partners that we lose. If we fail to develop or maintain strategic relationships
with companies that develop necessary technologies or create industry standards,
our products could become obsolete. We could also be at a competitive
disadvantage in attempting to negotiate relationships with those potential
partners in the future. In addition, if any strategic partner breaches or
terminates its relationship with us, we may not be able to sustain or grow our
business.

OUR FAILURE TO ENHANCE OUR EXISTING PRODUCTS OR DEVELOP AND INTRODUCE NEW
PRODUCTS THAT MEET CHANGING CUSTOMER REQUIREMENTS AND TECHNOLOGICAL ADVANCES
WOULD LIMIT OUR ABILITY TO SELL OUR PRODUCTS.

         Our ability to increase net revenue will depend significantly on
whether we are able to anticipate or adapt to rapid technological innovation in
the telecommunication industry and to offer, on a timely and cost-effective
basis, products that meet changing customer demands and industry standards. If
the standards adopted are different from those which we have chosen to support,
market acceptance of our products may be significantly reduced or delayed.

         Developing new or enhanced products is a complex and uncertain process
and we may not have sufficient resources to successfully and accurately
anticipate technological and market trends, or to successfully manage long
development cycles. We must manage the transition from our older products to new
or enhanced products to minimize disruption in customer ordering patterns and
ensure that adequate supplies of new products are available for delivery to meet
anticipated customer demand. Any significant delay or failure to release new
products or product enhancements on a timely and cost-effective basis could harm
our reputation and customer

                                       14
<PAGE>   15
relationships, provide a competitor with a first-to-market opportunity or allow
a competitor to achieve greater market share.

TELECOMMUNICATIONS NETWORKS ARE COMPRISED OF MULTIPLE HARDWARE AND SOFTWARE
PRODUCTS FROM MULTIPLE VENDORS. IF OUR PRODUCTS ARE NOT COMPATIBLE WITH OTHER
COMPANIES' PRODUCTS WITHIN OUR CUSTOMERS' NETWORKS, ORDERS WILL BE DELAYED OR
CANCELLED AND SUBSTANTIAL PRODUCT RETURNS COULD OCCUR.

         Many of our customers require that our products be designed to work
with their existing networks, each of which may have different specifications
and utilize multiple protocols that govern the way devices on the network
communicate with each other. Our customers' networks may contain multiple
generations of products from different vendors that have been added over time as
their networks have grown and evolved. Our products may be required to work with
these products as well as with future products in order to meet our customers'
requirements. In some cases, we may be required to modify our product designs to
achieve a sale, which may result in a longer sales cycle, increased research and
development expense, and reduced operating margins. If our products are not
compatible with existing equipment in our customers' networks, whether open or
proprietary, installations could be delayed, orders for our products could be
cancelled or our products could be returned.

IF WE FAIL TO WIN CONTRACTS AT THE BEGINNING OF OUR TELECOMMUNICATIONS
CUSTOMERS' DEPLOYMENT CYCLES, WE MAY NOT BE ABLE TO SELL PRODUCTS TO THOSE
CUSTOMERS FOR AN EXTENDED PERIOD OF TIME, WHICH COULD INHIBIT OUR GROWTH.

         Our existing and potential telecommunications customers generally
select a limited number of suppliers at the beginning of a deployment cycle. As
a result, if we are not selected as one of these suppliers, we may not have an
opportunity to sell products to that customer until its next purchase cycle,
which may be an extended period of time. In addition, if we fail to win
contracts from existing and potential customers that are at an early stage in
their design cycle, our ability to sell products to these customers in the
future may be adversely affected because they may prefer to continue purchasing
products from their existing vendor. Since we rely on a small number of
customers for the majority of our sales, our failure to capitalize on limited
opportunities to win contracts with these customers would severely harm us.

SINCE THE TELECOMMUNICATIONS INDUSTRY IS CHARACTERIZED BY LARGE PURCHASE ORDERS
PLACED ON AN IRREGULAR BASIS, IT IS DIFFICULT TO ACCURATELY FORECAST THE TIMING
AND SIZE OF ORDERS. ACCORDINGLY, OUR REVENUE AND OPERATING RESULTS MAY VARY
SIGNIFICANTLY AND UNEXPECTEDLY FROM QUARTER TO QUARTER.

         We may receive purchase orders for significant dollar amounts on an
irregular basis depending upon the timing of our customers' network deployment
and sales and marketing efforts. Because orders we receive may have short lead
times, we may not have sufficient inventory to fulfill these orders, and we may
incur significant costs in attempting to expedite and fulfill these orders. In
addition, orders expected in one quarter could shift to another because of the
timing of our customers' purchase decisions and order reductions or
cancellations. Under our OEM agreements, our OEM customers have the right to
delay previously-placed orders for any reason. The time required for our
customers to incorporate our products into their own can vary significantly and
generally exceeds several months, which further complicates our planning
processes and reduces the predictability of our operating results. Accordingly,
our revenue and operating results may vary significantly and unexpectedly from
quarter to quarter.


                                       15
<PAGE>   16
         Our customers have in the past built, and may in the future build,
significant inventory in order to facilitate more rapid deployment of
anticipated major projects or for other reasons. After building a significant
inventory of our products, these parties may be faced with delays in these
anticipated major projects for various reasons. As a result, these customers may
be required to maintain a significant inventory of our products for longer
periods than they originally anticipated, which would reduce further purchases.
These reductions, in turn, could cause fluctuations in our future results of
operations and severely harm our business and financial condition.

SINCE THE SALES CYCLE FOR OUR PRODUCTS IS TYPICALLY LONG AND UNPREDICTABLE, WE
HAVE DIFFICULTY PREDICTING FUTURE REVENUES AND OUR REVENUE AND OPERATING RESULTS
MAY FLUCTUATE SIGNIFICANTLY.

         A customer's decision to purchase our products often involves a
significant commitment of its resources and a lengthy evaluation and product
qualification process. Our sales cycle typically lasts from nine months to one
year. As a result, we may incur substantial sales and marketing expenses and
expend significant management effort without any assurance of a sale. A long
sales cycle also subjects us to other risks, including customers' budgetary
constraints, internal acceptance reviews and order reductions or cancellations.
Even after deciding to purchase our products, our customers often deploy our
products slowly.

WE HAVE A LIMITED ORDER BACKLOG. IF WE DO NOT OBTAIN SUBSTANTIAL ORDERS IN A
QUARTER, WE MAY NOT MEET OUR REVENUE OBJECTIVES FOR THAT QUARTER.

         Since inception, our order backlog at the beginning of each quarter has
not been significant, and we expect this trend to continue for the foreseeable
future. Accordingly, we must obtain substantial additional orders in a quarter
for shipments in that quarter to achieve our revenue objectives. Our sales
agreements allow purchasers to delay scheduled delivery dates without penalty.
Our customer purchase orders also allow purchasers to cancel orders within
negotiated time frames without significant penalty. In addition, due in part to
factors such as the timing of product release dates, purchase orders and product
availability, significant volume shipments of our products could occur near the
end of our fiscal quarters. If we fail to ship products by the end of a quarter,
our operating results would be adversely affected for that quarter.

WE DEPEND UPON A SINGLE CONTRACTOR TO MANUFACTURE OUR PRODUCTS. TERMINATION OF
THIS RELATIONSHIP WOULD IMPOSE SIGNIFICANT COSTS ON US AND COULD HARM OR
INTERFERE WITH OUR ABILITY TO MEET SCHEDULED PRODUCT DELIVERIES.

         We do not have internal manufacturing capabilities. We have relied on a
sole manufacturer, PCB Assembly, Inc., to build our products. PCB Assembly was
recently acquired by Flextronics International Limited. Although our contract
remains in effect, Flextronics may cancel it on 60 days' notice and is not
obligated to supply products to us for any specific period, in any specific
quantity or at any specific price, except as may be provided in a particular
purchase order. Our reliance on Flextronics involves a number of risks,
including the lack of operating history between us and Flextronics, the absence
of control over our manufacturing capacity, the unavailability of, or
interruptions in, access to process technologies and reduced control over
component availability, delivery schedules, manufacturing yields and costs. We
are currently evaluating Flextronics' ability to manufacture our products in
required volumes. If we decide that Flextronics is unable to meet our needs, we
will have to identify and qualify one or more acceptable alternative
manufacturers, which could result in substantial manufacturing


                                       16
<PAGE>   17
delays and cause us to incur significant costs. It is possible that an alternate
source may not be available to us when needed or be in a position to satisfy our
production requirements at acceptable prices and quality. Any significant
interruption in manufacturing would harm our ability to meet our scheduled
product deliveries to our customers, harm our reputation and could cause the
loss of existing or potential customers, any of which could seriously harm our
business and operating results.

WE DEPEND ON SOLE SOURCE AND LIMITED SOURCE SUPPLIERS FOR KEY COMPONENTS. IF WE
ARE UNABLE TO BUY COMPONENTS ON A TIMELY BASIS, WE WILL NOT BE ABLE TO DELIVER
OUR PRODUCTS TO OUR CUSTOMERS ON TIME WHICH COULD CAUSE US TO LOSE CUSTOMERS. IF
WE PURCHASE EXCESS COMPONENTS TO REDUCE THIS RISK, WE MAY INCUR SIGNIFICANT
INVENTORY COSTS.

         We obtain several of the key components used in our products, including
interface circuits, microprocessors, digital signal processors, digital
subscriber line modules and flash memory, from single or limited sources of
supply. We have encountered, and expect in the future to encounter, difficulty
in obtaining these components from our suppliers. As recently as the fourth
quarter of 1999, we experienced a severe shortage of components, particularly
subscriber line interface circuits, which jeopardized our ability to deliver our
products in a timely fashion. We purchase most components on a purchase order
basis and we do not have guaranteed supply arrangements with most of our key
suppliers. Financial or other difficulties faced by our suppliers or significant
changes in demand for these components could limit the availability of these
components to us at acceptable prices and on a timely basis, if at all. Any
interruption or delay in the supply of any of these components, or our inability
to obtain these components from alternate sources at acceptable prices and
within a reasonable amount of time, would limit our ability to meet scheduled
product deliveries to our customers or force us to reengineer our products,
which may hurt our gross margins and our ability to deliver products on a timely
basis, if at all. A substantial period of time could be required before we would
begin receiving adequate supplies from alternative suppliers, if available. In
addition, qualifying additional suppliers is time consuming and expensive and
exposes us to potential supplier production difficulties or quality variations.

IF WE DO NOT PREDICT OUR MANUFACTURING REQUIREMENTS ACCURATELY, WE COULD INCUR
ADDITIONAL COSTS AND SUFFER MANUFACTURING DELAYS.

         We currently provide forecasts of our demand to our contract
manufacturer 12 months prior to scheduled delivery of products to our customers.
Lead times for the materials and components that we order vary significantly and
depend on numerous factors, including the specific supplier, contract terms and
demand for a component at a given time. If we overestimate our component
requirements, our contract manufacturer may purchase excess inventory. For those
parts that are unique to our products, we could be required to pay for these
excess parts and recognize related inventory write-down costs. If we
underestimate our requirements, our contract manufacturer may have an inadequate
inventory, which could interrupt manufacturing of our products and result in
delays in shipments and revenue.

THE COMPETITION FOR QUALIFIED PERSONNEL IS PARTICULARLY INTENSE IN OUR INDUSTRY
AND IN NORTHERN CALIFORNIA. IF WE ARE UNABLE TO ATTRACT AND RETAIN KEY
PERSONNEL, WE MAY NOT BE ABLE TO SUSTAIN OR GROW OUR BUSINESS.

         Our success depends to a significant degree upon the continued
contributions of the principal members of our sales, marketing, engineering and
management personnel, many of


                                       17
<PAGE>   18
whom would be difficult to replace. None of our officers or key employees is
bound by an employment agreement for any specific term, and we do not have "key
person" life insurance policies covering any of our employees. The competition
for qualified personnel is particularly intense in our industry and in Northern
California, where there is a high concentration of established and emerging
growth technology companies. This competition makes it more difficult to retain
our key personnel and to recruit new highly qualified personnel. To attract and
retain qualified personnel, we may be required to grant large option or other
stock-based incentive awards, which may be highly dilutive to existing . We may
also be required to pay significant base salaries and cash bonuses to attract
and retain these individuals, which payments could harm our operating results.
In particular, we have experienced difficulty in hiring software and system test
engineers and engineers with voice and data experience. We believe that we will
continue to experience difficulty in recruiting and retaining qualified
personnel in the future. If we are not able to attract and retain the necessary
personnel, we could face delays in developing our products and implementing our
sales and marketing plans, and we may not be able to grow our business.

WE PLAN TO INVEST A SIGNIFICANT AMOUNT OF OUR RESOURCES TO FUND THE DEVELOPMENT,
MARKETING AND SALE OF OUR PRODUCTS; HOWEVER, IF WE ARE UNABLE TO EXPAND OUR
SALES AND MARKETING OPERATIONS, WE WILL NOT BE ABLE TO ACHIEVE BRAND AWARENESS
FOR OUR PRODUCTS AND GENERATE ADDITIONAL SALES.

         We plan to increase significantly our operating expenses to fund
greater levels of research and development, expand our sales and marketing
operations, broaden our customer support capabilities and develop new
distribution channels. We also plan to expand our general and administrative
capabilities to address the demands resulting from this offering and the
expected continued growth of our business. Our operating expenses are largely
based on anticipated personnel requirements and revenue trends, and a high
percentage of our expenses are, and will continue to be, fixed. In addition, we
may be required to spend more for research and development than originally
budgeted in order to respond to industry trends. As a result, any delay in
generating or recognizing revenue could cause significant variations in our
operating results from quarter to quarter and could result in substantial
operating losses. We have rapidly and significantly expanded our operations in
recent periods. Our business will be harmed if we fail to manage effectively the
growth of our operations.


WE HAVE RAPIDLY AND SIGNIFICANTLY EXPANDED OUR OPERATIONS IN RECENT PERIODS.
THIS EXPANSION SIGNIFICANTLY STRAINS OUR MANAGERIAL, OPERATIONAL AND FINANCIAL
RESOURCES.

     Some of our senior management personnel joined us within the last 15
months. Our President, Vice President of Finance and Administration, Vice
President of Marketing, Vice President of Operations, Vice President of Human
Resources and Vice President of Sales have all joined us since June 1999. To
manage the expected growth of our operations and personnel, we will be required
to:

-        improve existing and implement new operational, financial and
         management controls, reporting systems and procedures;

-        hire, train, motivate and manage additional qualified personnel;

-        expand access to additional manufacturing capacity;

-        effectively manage multiple relationships with our customers,
         suppliers, distributors and other third parties; and


                                       18
<PAGE>   19
-        coordinate our domestic and international operations and establish the
         necessary infrastructure to implement our international strategy.

     If we are not able to manage the growth of our operations in an efficient
and timely manner, our business will be severely harmed.

THE TELECOMMUNICATIONS MARKET IS BECOMING INCREASINGLY GLOBAL. WHILE WE PLAN TO
EXPAND INTERNATIONALLY, WE HAVE LIMITED EXPERIENCE OPERATING IN INTERNATIONAL
MARKETS. IN OUR EFFORTS TO EXPAND INTERNATIONALLY, WE COULD BECOME SUBJECT TO
NEW RISKS WHICH COULD HAMPER OUR ABILITY TO ESTABLISH AND MANAGE OUR
INTERNATIONAL OPERATIONS.

     We have sales and customer support personnel in the United Kingdom and have
initiated distribution relationships covering Germany, France, Australia and New
Zealand. We intend to further expand our international operations and enter new
markets. This expansion will require significant management attention and
financial resources. We have limited experience in marketing and distributing
our products internationally and in developing versions of our products that
comply with local standards. In addition, our international operations will be
subject to other inherent risks, including:

-        the failure to adopt regulatory changes that facilitate the
         provisioning of competitive communications services;

-        difficulties adhering to international protocol standards;

-        expenses associated with customizing products for other countries;

-        protectionist laws and business practices that favor local competition;

-        reduced protection for intellectual property rights in some countries;

-        difficulties enforcing agreements through other legal systems and in
         complying with foreign laws;

-        fluctuations in currency exchange rates;

-        political and economic instability; and

-        import or export licensing requirements.

OUR PRODUCTS REQUIRE SUBSTANTIAL INVESTMENT OVER A LONG PRODUCT DEVELOPMENT
CYCLE, AND WE MAY NOT REALIZE ANY RETURN ON OUR INVESTMENT.

         The development of new or enhanced products is a complex and uncertain
process. We and our OEM manufacturers have in the past and may in the future
experience design, manufacturing, marketing and other difficulties that could
delay or prevent the development, introduction or marketing of new products and
enhancements. For example, we recently experienced delays in availability of our
DSL eLink products. Development costs and expenses are incurred before we
generate any revenues from sales of products resulting from these efforts. Our
total research and development expenses were approximately $4.3 million in the
first nine months ended September 30, 1999 and $8.6 million for the nine months
ended September 30, 2000. We intend to continue to incur substantial research
and development expenses, which could have a negative impact on our earnings in
future periods.


                                       19
<PAGE>   20
IF OUR PRODUCTS CONTAIN UNDETECTED SOFTWARE OR HARDWARE ERRORS, WE COULD INCUR
SIGNIFICANT UNEXPECTED EXPENSES, EXPERIENCE PRODUCT RETURNS AND LOST SALES AND
BE SUBJECT TO PRODUCT LIABILITY CLAIMS.

         Our products are highly technical and are designed to be deployed in
very large and complex networks. While our products have been tested, because of
their nature, they can only be fully tested when deployed in networks that
generate high amounts of voice or data traffic. Because of our short operating
history, our products have not yet been broadly deployed. Consequently, our
customers may discover errors or defects in our products after they have been
broadly deployed. In addition, our customers may use our products in conjunction
with products from other vendors. As a result, when problems occur, it may be
difficult to identify the source of the problem. Any defects or errors in our
products discovered in the future, or failures of our customers' networks,
whether caused by our products or another vendor's products, could result in
loss of customers or decrease in revenue and market share.

         We may be subject to significant liability claims because our products
are used in connection with critical communications services. Our agreements
with customers typically contain provisions intended to limit our exposure to
liability claims. However, these limitations may not preclude all potential
claims resulting from a defect in one of our products. Liability claims could
require us to spend significant time and money in litigation or to pay
significant damages. Any of these claims, whether or not successful, could
seriously damage our reputation and business.

THE COMPLEX NATURE OF OUR TELECOMMUNICATIONS PRODUCTS REQUIRES US TO PROVIDE OUR
CUSTOMERS WITH A HIGH LEVEL OF SERVICE AND SUPPORT BY HIGHLY TRAINED PERSONNEL.
IF WE DO NOT EXPAND OUR CUSTOMER SERVICE AND SUPPORT ORGANIZATION, WE WILL NOT
BE ABLE TO MEET OUR CUSTOMERS' DEMANDS.

         We currently have a small customer service and support organization,
and we will need to increase these resources to support any increase in the
needs of our existing and new customers. Hiring customer service and support
personnel in our industry is very competitive due to the limited number of
people available with the necessary technical skills and understanding of our
technologies. We currently plan to use Timeplex, Inc. to install and maintain
our products, including in connection with our planned international expansion,
when our customers request these services. Our agreement with Timeplex expires
in August 2001, and may be terminated earlier upon 60 days' notice. If our
relationship with Timeplex ends, we may be unable to find a replacement or to
establish the necessary capabilities internally. If we are unable to expand or
maintain our customer service and support organization, or if Timeplex fails to
install or maintain our products appropriately, our customers may become
dissatisfied and we could lose customers and our reputation could be harmed. A
reputation for poor service would prevent us from increasing sales to existing
or new customers.

WE RELY ON A COMBINATION OF PATENT, COPYRIGHT, TRADEMARK AND TRADE SECRET LAWS,
AS WELL AS CONFIDENTIALITY AGREEMENTS AND LICENSING ARRANGEMENTS, TO ESTABLISH
AND PROTECT OUR PROPRIETARY RIGHTS. FAILURE TO PROTECT OUR INTELLECTUAL PROPERTY
WILL LIMIT OUR ABILITY TO COMPETE AND RESULT IN A LOSS OF A COMPETITIVE
ADVANTAGE AND DECREASED REVENUE.

         Our success and ability to compete depend substantially on our
proprietary technology. Any infringement of our proprietary rights could result
in significant litigation costs, and any failure to adequately protect our
proprietary rights could result in our competitors offering similar products,
potentially resulting in loss of a competitive advantage and decreased revenue.


                                       20
<PAGE>   21
We presently have three U.S. patent applications pending, but no issued patents.
Despite our efforts to protect our proprietary rights, existing copyright,
trademark and trade secret laws afford only limited protection. In addition, the
laws of many foreign countries do not protect our proprietary rights to the same
extent as do the laws of the United States. Attempts may be made to copy or
reverse engineer aspects of our products or to obtain and use information that
we regard as proprietary. Accordingly, we may not be able to protect our
proprietary rights against unauthorized third-party copying or use. Furthermore,
policing the unauthorized use of our products is difficult. Litigation may be
necessary in the future to enforce our intellectual property rights, to protect
our trade secrets or to determine the validity and scope of the proprietary
rights of others. This litigation could result in substantial costs and
diversion of resources and may not ultimately be successful.

WE MAY BE SUBJECT TO INTELLECTUAL PROPERTY INFRINGEMENT CLAIMS THAT ARE COSTLY
TO DEFEND AND COULD LIMIT OUR ABILITY TO USE SOME TECHNOLOGIES IN THE FUTURE.

         Our industry is characterized by frequent intellectual property
litigation based on allegations of infringement of intellectual property rights.
From time to time, third parties have asserted, and may assert in the future,
patent, copyright, trademark and other intellectual property rights to
technologies or rights that are important to our business. For example, we
recently received letters from Sonoma Systems alleging that one of our products
infringes a patent owned by Sonoma Systems and inviting us to discuss licensing
their patent. In addition, our agreements may require that we indemnify our
customers for any expenses or liabilities resulting from claimed infringements
of patents, trademarks or copyrights of third parties. Any claims asserting that
our products infringe or may infringe the proprietary rights of third parties,
with or without merit, could be time-consuming, resulting in costly litigation
and diverting the efforts of our technical and management personnel. These
claims could cause us to stop selling, incorporating or using our products that
use the challenged intellectual property and could also result in product
shipment delays or require us to redesign or modify our products or enter into
licensing agreements. These licensing agreements, if required, would increase
our product costs and may not be available on terms acceptable to us, if at all.

IF NECESSARY LICENSES OF THIRD-PARTY TECHNOLOGY ARE NOT AVAILABLE TO US OR ARE
VERY EXPENSIVE, WE MAY BE UNABLE TO DEVELOP NEW PRODUCTS OR PRODUCT
ENHANCEMENTS.

         From time to time we may be required to license technology from third
parties to develop new products or product enhancements. These third-party
licenses may not be available to us on commercially reasonable terms, if at all.
Our inability to obtain necessary third-party licenses may force us to obtain
substitute technology of lower quality or performance standards or at greater
cost, any of which could seriously harm the competitiveness of our products.

BECAUSE OUR HEADQUARTERS ARE LOCATED IN NORTHERN CALIFORNIA, WHICH IS A REGION
CONTAINING ACTIVE EARTHQUAKE FAULTS, IF A NATURAL DISASTER OCCURS, OUR BUSINESS
COULD BE SHUT DOWN OR SEVERELY IMPACTED.

         Our business and operations depend on the extent to which our facility
and products are protected against damage from fire, earthquakes, power loss and
similar events. Despite precautions taken by us, a natural disaster or other
unanticipated problem could, among other things, hinder our research and
development efforts, delay the shipment of our products and affect our ability
to receive and fulfill orders. For example, since we conduct all of our final
assembly and tests in one location, any fire or other disaster at the assembly
facility would severely harm our business.

        RISKS ASSOCIATED WITH THE MULTISERVICE BROADBAND ACCESS INDUSTRY

INTENSE COMPETITION IN THE MARKET FOR OUR TELECOMMUNICATIONS PRODUCTS COULD
PREVENT US FROM INCREASING OR SUSTAINING OUR REVENUE AND PREVENT US FROM
ACHIEVING OR SUSTAINING PROFITABILITY.

         The market for multiservice broadband access products is highly
competitive. We compete directly with numerous companies, including Accelerated
Networks, ADTRAN, Carrier Access, Cisco Systems, Efficient Networks, Lucent
Technologies, Nortel Networks and Polycom. Many of our current and potential
competitors have longer operating histories, greater name recognition,
significantly greater selling and marketing, technical, manufacturing,
financial, customer support, professional services and other resources,
including vendor-sponsored financing programs. As a result, these competitors
are able to devote greater resources to the development, promotion, sale and
support of their products to leverage their customer bases and broaden product
offerings to gain market share. In addition, our competitors may foresee the
course of market developments more accurately than we do and could develop new
technologies that compete with our products or even render our products
obsolete. We may not have sufficient resources to continue to make the
investments or achieve the technological advances necessary to compete
successfully with existing or new competitors. In addition, due to the rapidly
evolving markets in which we compete, additional competitors with significant
market presence and financial resources, including other large
telecommunications equipment manufacturers, may enter our markets, thereby
further intensifying competition.

         We believe that our existing OEM customers continuously evaluate
whether to offer their own multiservice broadband access devices. If any of our
OEM customers decide to internally design and sell their own multiservice
broadband access devices, or acquire one or more of our competitors or their
broadband access technologies, it could eliminate or substantially reduce its
purchases of our products. In addition, our current growth may cause some OEM
customers to view us as greater competition. Our OEM relationships could also be
harmed as we develop and market new products that may compete directly with the
products of our OEM customers. We cannot assure you that any of our OEM
customers will continue to rely, or expand their reliance, on us as an external
source of supply for their multiservice broadband access devices. Because we
rely on only a few OEM customers for a substantial portion of our revenues, any
loss of sales to these OEM customers would seriously harm our business,
financial condition and results of operations.

BECAUSE OUR INDUSTRY IS CHARACTERIZED BY CONSOLIDATION, WE COULD POTENTIALLY
LOSE CUSTOMERS, WHICH WOULD HARM OUR BUSINESS.

         The markets in which we compete are characterized by increasing
consolidation, as exemplified by the recent or pending acquisitions of Sonoma
Systems by Nortel Networks, FlowPoint by Efficient Networks, PairGain
Technologies by ADC Telecommunications and Newbridge Networks by Alcatel. We
cannot predict how industry consolidation will affect our competitors and we may
not be able to compete successfully in an increasingly consolidated industry.

OUR PRODUCTS ARE SUBJECT TO PRICE REDUCTION AND MARGIN PRESSURES. IF OUR AVERAGE
SELLING PRICES DECLINE AND WE FAIL TO OFFSET THAT DECLINE THROUGH COST
REDUCTIONS, OUR GROSS MARGINS AND POTENTIAL PROFITABILITY WOULD BE SERIOUSLY
HARMED.


                                       22
<PAGE>   23
         In the past, competitive pressures have forced us to reduce the prices
of our products. In the second quarter of 1999, we reduced the price of our T1
Integrator product in response to competition, which reduced our gross margins
in subsequent periods. We expect similar price reductions to occur in the future
in response to competitive pressures. In addition, our average selling prices
decline when we negotiate volume price discounts with customers and utilize
indirect distribution channels. If our average selling prices decline and we
fail to offset that decline through cost reductions, our gross margins and
potential profitability would be seriously harmed.

SALES OF OUR PRODUCTS DEPEND ON THE WIDESPREAD ADOPTION OF MULTISERVICE
BROADBAND ACCESS SERVICES AND IF THE DEMAND FOR MULTISERVICE BROADBAND ACCESS
SERVICES DOES NOT DEVELOP, THEN OUR RESULTS OF OPERATIONS AND FINANCIAL
CONDITION WOULD BE HARMED.

     Our business will be harmed if the demand for multiservice broadband access
services does not increase as rapidly as we anticipate, or if our customers'
multiservice broadband access service offerings are not well received in the
marketplace. Critical factors affecting the development of the multiservice
broadband access services market include:

-        the development of a viable business model for multiservice broadband
         access services, including the capability to market, sell, install and
         maintain these services;

-        cost constraints, such as installation, space and power requirements at
         the central offices of incumbent local exchange carriers, or ILECs;

-        compatibility of equipment from multiple vendors in service provider
         networks;

-        evolving industry standards for transmission technologies and transport
         protocols;

-        varying and uncertain conditions of the communications network
         infrastructure, including quality and complexity, electrical
         interference, and crossover interference with voice and data
         telecommunications services;

-        domestic and foreign government regulation; and

-        the ability of competitive local exchange carriers, or CLECs, to obtain
         sufficient funding and to successfully grow their businesses.

     The market for multiservice broadband access devices may fail to develop
for other reasons or may develop more slowly than anticipated, which would harm
our business.

IF WE FAIL TO COMPLY WITH REGULATIONS AND EVOLVING INDUSTRY STANDARDS, SALES OF
OUR EXISTING AND FUTURE PRODUCTS COULD BE HARMED.

         The markets for our products are characterized by a significant number
of communications regulations and standards, some of which are evolving as new
technologies are deployed. Our customers may require our products to comply with
various standards, including those promulgated by the Federal Communications
Commission, or FCC, standards established by Underwriters Laboratories and
Telcordia Technologies or proprietary standards promoted by our competitors. In
addition, our key competitors may establish proprietary standards which they
might not make available to us. As a result, we may not be able to achieve
compatibility with their products. Internationally, we may also be required to
comply with standards established by telecommunications authorities in various
countries as well as with recommendations of the International
Telecommunications Union.

OUR CUSTOMERS ARE SUBJECT TO GOVERNMENT REGULATION, AND CHANGES IN CURRENT OR
FUTURE LAWS OR REGULATIONS THAT NEGATIVELY IMPACT OUR CUSTOMERS COULD HARM OUR
BUSINESS.


                                       23
<PAGE>   24
         The jurisdiction of the FCC extends to the entire communications
industry, including our customers. Future FCC regulations affecting the
broadband access industry, our customers or their service offerings may harm our
business. For example, FCC regulatory policies that affect the availability of
data and Internet services may impede our customers' penetration into markets or
affect the prices that they are able to charge. In addition, international
regulatory bodies are beginning to adopt standards and regulations for the
broadband access industry. If our customers are hurt by laws or regulations
regarding their business, products or service offerings, demand for our products
may decrease.

                ADDITIONAL RISKS THAT MAY AFFECT OUR STOCK PRICE

OUR STOCK PRICE MAY BE VOLATILE, AND YOU MAY NOT BE ABLE TO RESELL OUR SHARES AT
OR ABOVE THE PRICE YOU PAID, OR AT ALL.

         On August 15, 2000, we completed our initial public offering. Prior to
our initial public offering there had not been a public market for our common
stock. The stock market in general, and the Nasdaq National Market and
technology companies in particular, have experienced extreme price and volume
fluctuations that have often been unrelated or disproportionate to the operating
performance of companies. The trading prices and valuations of many technology
companies are substantially above historical levels. These trading prices and
valuations may not be sustainable. These broad market and industry factors may
decrease the market price of our common stock, regardless of our actual
operating performance.

OUR MANAGEMENT HAS BROAD DISCRETION AS TO HOW TO USE THE PROCEEDS FROM OUR
INITIAL PUBLIC OFFERING AND THE PROCEEDS MAY NOT BE USED IN A MANNER WITH WHICH
YOU AGREE.

         We intend to use the proceeds from our initial public offering for
general corporate purposes, including working capital and capital expenditures,
and we may use a portion of the proceeds to acquire complementary businesses,
products or technologies and expand our sales and marketing efforts. However, to
date, we have not designated any specific uses for the initial public offering
proceeds. We will have broad discretion over how we use these proceeds. You will
not have the opportunity to evaluate the economic, financial or other
information on which we base our decisions regarding how to use the proceeds
from our initial public offering, and we may spend these proceeds in ways with
which you may disagree. Pending any of these uses, we plan to invest the
proceeds from our initial public offering in short-term, investment-grade,
interest-bearing securities. We cannot predict whether these investments will
yield a favorable return.

WE MAY ENGAGE IN FUTURE ACQUISITIONS OR STRATEGIC INVESTMENTS THAT WE MAY NOT BE
ABLE TO SUCCESSFULLY INTEGRATE OR MANAGE, WHICH COULD HURT OUR BUSINESS. THESE
ACQUISITIONS OR STRATEGIC INVESTMENTS MAY ALSO DILUTE OUR STOCKHOLDERS AND CAUSE
US TO INCUR DEBT AND ASSUME CONTINGENT LIABILITIES.

         We may review acquisition prospects and strategic investments that
could complement our current product offerings, augment our market coverage,
enhance our technical capabilities or otherwise offer growth opportunities. For
example, on October 30, 2000, we entered into a definitive merger agreement to
acquire Woodwind Communications Systems, Inc, a provider of voice-over-broadband
network edge access solutions. Pursuant to the merger agreement, we will acquire
Woodwind for 4,950,000 shares (subject to adjustment under certain
circumstances) of common stock, including the assumption of Woodwind's stock
options. The issuance of equity securities in connection with


                                       24

<PAGE>   25
these acquisitions or investments could significantly dilute our investors. If
we incur or assume debt in connection with these acquisitions or investments, we
may incur interest charges that could harm our net income. We have little
experience in evaluating, completing, managing or integrating acquisitions and
strategic investments. Acquisitions and strategic investments may entail
numerous integration risks and impose costs on us, including:

-        difficulties in assimilating acquired operations, technologies or
         products including the loss of key employees;

-        unanticipated costs;

-        diversion of management's attention from our core business concerns;

-        adverse effects on business relationships with our suppliers and
         customers or those of the acquired businesses;

-        risks of entering markets in which we have no or limited prior
         experience;

-        assumption of contingent liabilities;

-        incurrence of significant amortization expenses related to goodwill and
         other intangible assets; and

-        incurrence of significant write-offs.

WE MAY NEED TO RAISE MORE CAPITAL, BUT THE AVAILABILITY OF ADDITIONAL FINANCING
IS UNCERTAIN. IF ADEQUATE FUNDS ARE NOT AVAILABLE OR ARE NOT AVAILABLE ON
ACCEPTABLE TERMS, WE MAY BE UNABLE TO DEVELOP OR ENHANCE OUR PRODUCTS AND
SERVICES, TAKE ADVANTAGE OF FUTURE OPPORTUNITIES OR RESPOND TO COMPETITIVE
PRESSURES, WHICH COULD NEGATIVELY IMPACT OUR PRODUCT DEVELOPMENT AND SALES.

         If our capital requirements vary significantly from those currently
planned, we may require additional financing sooner than anticipated. If
additional funds are raised through the issuance of equity securities, the
percentage of equity ownership of our existing stockholders will be reduced. In
addition, holders of these equity securities may have rights, preferences or
privileges senior to those of the holders of our common stock. If additional
funds are raised through the issuance of debt securities, we may incur
significant interest charges, and these securities would have rights,
preferences and privileges senior to holders of common stock. The terms of these
securities could also impose restrictions on our operations. Additional
financing may not be available when needed on terms favorable to us or at all.
If adequate funds are not available or are not available on acceptable terms, we
may be unable to develop or enhance our products and services, take advantage of
future opportunities or respond to competitive pressures, which could negatively
impact our product development and sales. Substantial future sales of our common
stock in the public market could cause our stock price to fall. Many corporate
actions would be controlled by officers, directors and affiliated entities, if
they acted together, regardless of the desire of other investors to pursue an
alternative course of action.

SUBSTANTIAL FUTURE SALES OF OUR COMMON STOCK IN THE PUBLIC MARKET COULD CAUSE
OUR STOCK PRICE TO FALL.

         Additional sales of our common stock in the public market after our
initial public offering, or the perception that such sales could occur, could
cause the market price of our common stock to decline. After the close of our
public offering on August 15, 2000, and the exercise by the underwriters of
their overallotment option on September 5, 2000, we had approximately 32,525,937
shares of common stock outstanding. The 3.45 million shares sold in our public
offering and 329,500 shares which were outstanding prior to the public offering
will be freely transferable without restriction or additional registration under
the Securities Act of 1933 (other than any of


                                       25
<PAGE>   26
these shares that may be purchased by our "affiliates" as defined in Rule 144(a)
under the Securities Act). The remaining shares of common stock outstanding
after this offering will be available for sale, assuming the effectiveness of
lock-up agreements under which our stockholders have agreed not to sell or
otherwise dispose of their shares of common stock in the public market, as
follows:
<TABLE>

February 7, 2001                                    26,511,408                         Shares saleable under Rule
(expiration at lock-up)                                                                144 or 701
</TABLE>

         In addition, Lehman Brothers may, in its sole discretion, at any time
without notice, release all or any portion of the shares subject to the lock-up
agreements, which would result in more shares being available for sale in the
public market at an earlier date. Sales of common stock by existing stockholders
in the public market, or the availability of the shares for sale, could
significantly reduce the market price of our common stock.

         In addition, we intend to file registration statements on Form S-8 with
the Securities and Exchange Commission covering approximately 17,714,199 shares
of common stock reserved for issuance under our stock incentive and employee
stock purchase plans. On February 7, 2001, at least 5,321,566 shares will be
subject to vested options, based on options outstanding on June 30, 2000. Sales
of a large number of these shares could decrease the market price of our common
stock.

         The holders of 17,694,657 shares of common stock have rights with
respect to registration of these shares for sale to the public. If these
holders, by exercising their registration rights, cause a large number of
securities to be registered and sold in the public market, the sales could
decrease the market price for our common stock. If we were to include in a
company-initiated registration shares held by these holders pursuant to the
exercise of their registration rights, these sales may hinder our ability to
raise needed capital.

MANY CORPORATE ACTIONS WOULD BE CONTROLLED BY OFFICERS, DIRECTORS AND AFFILIATED
ENTITIES, IF THEY ACTED TOGETHER, REGARDLESS OF THE DESIRE OF OTHER INVESTORS TO
PURSUE AN ALTERNATIVE COURSE OF ACTION.

         Our directors, executive officers and their affiliated entities
beneficially own approximately 57.8% of our outstanding common stock following
our initial public offering. These stockholders, if they acted together, could
exert control over matters requiring approval by our stockholders, including
electing directors and approving mergers or other business combination
transactions. This concentration of ownership may also discourage, delay or
prevent a change in control of our company, which could deprive our stockholders
of an opportunity to receive a premium for their stock as part of a sale of our
company and might reduce our stock price. These actions may be taken even if
they are opposed by our other stockholders, including those who purchase shares
in this offering.

DELAWARE LAW AND OUR CORPORATE CHARTER AND BYLAWS CONTAIN ANTI-TAKEOVER
PROVISIONS THAT WOULD DELAY OR DISCOURAGE TAKE OVER ATTEMPTS THAT STOCKHOLDERS
MAY CONSIDER FAVORABLE.

     Provisions in our amended and restated certificate of incorporation and
bylaws may have the


                                       26
<PAGE>   27
effect of delaying or preventing a change of control or changes in our
management. These provisions include:

-        the right of the board of directors to elect a director to fill a
         vacancy created by the expansion of the board of directors;

-        the ability of the board of directors to alter our bylaws without
         obtaining stockholder approval;

-        the establishment of a classified board of directors;

-        the ability of the board of directors to issue, without stockholder
         approval, up to five million shares of preferred stock with terms set
         by the board of directors which rights could be senior to those of
         common stock; and

-        the elimination of the right of stockholders to call a special meeting
         of stockholders and to take action by written consent.

Each of these provisions could discourage potential take over attempts and could
lower the market price of our common stock.

         In addition, because we are incorporated in Delaware, we are governed
by the provisions of Section 203 of the Delaware General Corporation Law. These
provisions may prohibit large stockholders, in particular those owning 15% or
more of our outstanding voting stock, from merging or combining with us. These
provisions in our charter, bylaws and under Delaware law could reduce the price
that investors might be willing to pay for shares of our common stock in the
future and result in the market price being lower than it would be without these
provisions.

ITEM 3:      QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK

          We are exposed to financial market risks related to interest rates and
foreign currency exchange rates. Our investments in commercial paper and bonds
of $43.9 million at September 30, 2000 are subject to interest rate risk, but
due to the short-term nature of these investments, a hypothetical 10% change in
the interest rate would not have a material impact on their value at September
30, 2000. There were no such investments at December 31, 1999. We also had debt
obligations of $1.0 million and $1.1 million at December 31, 1998 and 1999 and
which bear interest on a prime plus fixed basis. We do not hedge any interest
rate exposures and a hypothetical change of 10% in interest rates would not have
a material impact on the fair market value of these debt obligations. There was
no debt outstanding at September 30, 2000. To date, our international sales have
been denominated solely in U.S. dollars, and accordingly, we have not been
exposed to foreign currency rate fluctuations related to sales transactions.
However, the functional currency or our subsidiary in the United Kingdom is the
U.S. dollar and as the local accounts are maintained in British pounds, we are
subject to foreign currency exchange rate fluctuations associated with
remeasurement to U.S. dollars. A hypothetical change of 10% in the foreign
currency exchange rates would not have a material impact on our consolidated
financial position or results of operations.

RECENT ACCOUNTING PRONOUNCEMENTS

         In June 1998, the Financial Accounting Standards Board issued SFAS No.
133, "Accounting for Derivative Instruments and Hedging Activities." This
statement requires companies to record derivatives on the balance sheets as
assets or liabilities, measured at fair value. Gains or losses resulting from
changes in the values of those derivatives would be accounted for depending on
the use of the derivative and whether it qualifies for hedge accounting. SFAS
No. 133, as amended, will be effective for us beginning in 2001. Although we
have not fully assessed the implications of SFAS No. 133, we do not believe
adoption of this statement will have a material impact on our consolidated
financial position, results of operations or cash flows.

PART II:  OTHER INFORMATION

ITEM 2        Changes in Securities and Use of Proceeds

         (c) Changes in Securities.

         During the quarter ended September 30, 2000, and prior to the closing
of our IPO, we granted options to purchase 1,249,500 shares of common stock to
employees under our 1998 Stock Plan. During the quarter ended September 30,
2000, and prior to the closing of our IPO, employees of the Company exercised
options to purchase 673,909 shares of common stock. The


                                       28
<PAGE>   29
sale of the above securities was deemed to be exempt from registration under the
Securities Act of 1933 ("the Securities Act") in reliance upon Section 4(2) of
the Securities Act or Rule 701 promulgated under Section 3(b) of the Securities
Act.

         (d) Use of Proceeds from Sales of Registered Securities.

         On August 9, 2000, the SEC declared effective our Registration
Statement on Form S-1 (No. 333-36398), relating to the initial public offering
of our common stock. The managing underwriters in the offering were Lehman
Brothers Inc., Thomas Weisel Partners LLC and U.S. Bancorp Piper Jaffray Inc.
The offering commenced on August 10, 2000, and was closed on August 15, 2000,
after we had sold all of the 3,000,000 shares of common stock registered under
the Registration Statement. On September 15, 2000, the underwriters purchased
450,000 shares from us in connection with the exercise of the underwriters'
over-allotment option. The initial public offering price was $12 per share for
an aggregate initial public offering of $41,400,000 (including the 450,000
shares sold to the underwriters upon exercise of the over-allotment option),
netting proceeds of approximately $36.5 million to us after underwriting fees of
approximately $2.9 million and other offering expenses of approximately $2.0
million. None of these fees and expenses were paid to any director, officer,
general partner of the Company or their associates, persons owning 10% or
more of any class of equity securities of the Company or an affiliate
of the Company.

         The net proceeds were predominately held in a money market fund and
commercial paper and bonds as of September 30, 2000.
