                    NOTES TO CONDENSED FINANCIAL STATEMENTS

BASIS OF PRESENTATION

    The accompanying unaudited condensed financial statements have been prepared
by Interspeed, Inc. (the "Company") pursuant to the rules and regulations of the
Securities and Exchange Commission regarding interim financial reporting. They
should be read in conjunction with the audited financial statements included in
the Company's Annual Report on Form 10-K/A for the year ended September 30,
1999.

    In the opinion of management, the accompanying unaudited condensed financial
statements have been prepared on the same basis as the audited financial
statements and include all adjustments, consisting only of normal recurring
adjustments, necessary for a fair presentation of the interim periods presented.

    The operating results for the interim periods presented are not necessarily
indicative of the results which could be expected for the full year.

NET LOSS PER SHARE

    Basic net loss per share is computed using the weighted average number of
common shares outstanding during each period. Outstanding stock options have
been excluded from the computation of diluted per share amounts since the effect
would be antidilutive. Had the impact of stock options, using the treasury stock
method, been included in the computation, weighted average shares would have
increased by 11,858,000, 11,775,000, 9,248,000, and 9,205,000 for the three and
six months ended March 31, 2000 and 1999, respectively.

INCOME TAXES

    The Company's quarterly effective tax rate is based on the estimated tax
rate for the fiscal year.

COMPREHENSIVE INCOME

    There was no difference between the Company's net loss and its total
comprehensive loss for any of the periods presented.

SEGMENT INFORMATION

    The Company currently operates in one business segment: designing,
developing and marketing advanced communications products which enable service
providers to deliver high speed data access to small and medium sized
businesses, multi-tenant units ("MTUs"), and other organizations.

CONCENTRATION OF RISK

    To date, the Company's activities have been conducted primarily in the
United States. The Company performs ongoing credit evaluations of its customers
and generally requires no collateral. At March 31, 2000, approximately 96% of
the receivable balance was comprised of balances due from three customers.

    The Company relies on contract manufacturers and some single source
suppliers of materials for certain product components. As a result, should the
Company's current manufacturers or suppliers not produce and deliver inventory
for the Company to sell on a timely basis, operating results could be adversely
impacted.

SIGNIFICANT CUSTOMER AND GEOGRAPHIC INFORMATION

    The Company currently targets its sales efforts to data communications
service providers, MTUs, and other service organizations to both public and
private network providers and users across four related market segments. For the
three months and six months ended March 31, 2000, gross sales to United States'
customers amounted to $3,887,000 and $6,854,000, and export sales for the same
periods amounted to $116,000 and $301,000, respectively. For the three months
ended March 31, 2000, three customers accounted for approximately 50%, 23%, and
20% of gross revenue. For the six months ended March 31, 2000, the same three
customers accounted for approximately 51%, 31% and 11% of gross revenues.

RELATED PARTY TRANSACTIONS

    From its inception through the completion of its initial public offering on
September 24, 1999 ("IPO"), the Company's operations were funded through
contributions of capital and loans from Brooktrout, Inc. ("Brooktrout"), its
parent company. At September 24, 1999, in connection with the Company's IPO,
Brooktrout contributed $13,598,000, the majority of the outstanding note
balance, to the capital of the Company.

    The Company and Brooktrout entered into a Transition Services Agreement (the
"Agreement") which expired on December 31, 1999. The Agreement outlined certain
services that would continue to be performed on behalf of the Company by
Brooktrout through December 31, 1999. The Agreement required that these services
be phased out over a period beginning on October 1999 to December 1999. The
services included payroll processing and administration, human resources,
benefits, marketing, information technology and telecommunications, accounts
receivable, accounting and finance and order entry. The fees for such services
were on an "as used" basis and were included in the Agreement. During the three
months ended December 31, 1999, fees for services totaled $43,000.

WARRANTS

    In consideration for entering into certain long-tern reseller agreements,
the Company granted to the customers vested warrants to purchase 55,000 shares
of the Company's common stock at the market price of the Company's common stock
on the dates the warrants were granted. The value of the warrants was calculated
by applying the Black-Scholes option pricing model using the fair market value
of the Company's common stock on the date the agreements were executed. The
value of the warrants has been charged to expense as a component of stock
compensation and warrant charges in the condensed statement of operations.

    The Company also granted to the customers warrants to purchase up to 150,000
shares of the Company's common stock that vest installments as the customers
attain certain revenue milestones over

the terms of the agreements. The Company is accounting for these warrants as a
sales discount. As revenue is recognized on sales to these customers, the
Company is recording a sales discount based on the relationship of sales to date
to the customer to the specified revenue milestone. The amount of the discount
is being estimated by valuing the warrants using the Black-Scholes option
pricing model at the end of each fiscal period. The value of the warrants is
being adjusted in each fiscal period until the revenue levels are attained and
the warrants vest. The exercise price of the warrants is the fair market value
of the Company's common stock on the date that the warrants vest.

OVERVIEW

    REVENUE.  Our revenue is generated primarily from sales of our products and
related maintenance services to data communications service providers and their
customers. Revenue from product sales is recognized upon shipment of the
product. No revenue is recognized on products shipped on a trial basis. Our
products generally carry a one year warranty from the date of purchase. We
estimate sales returns and warranty costs at the time the product revenue is
recognized and an accrual is recorded. Customers may contract for support
services over and above that provided by our warranty policy. Revenue from such
contracts and from the extended warranty contracts is recognized ratably over
the service period. We do not recognize revenue on beta units until beta testing
on such units is completed.

    SALES DISCOUNTS--WARRANTS.  The Company granted to customers warrants to
purchase up to 150,000 shares of the Company's common stock that vest
installments as the customers attain certain revenue milestones over the terms
of the agreements. The Company is accounting for these warrants as a sales
discount. As revenue is recognized on sales to these customers, the Company is
recording a sales discount based on the relationship of sales to date to the
customer to the specified revenue milestone. The amount of the discount is being
estimated by valuing the warrants using the Black-Scholes option pricing model
at the end of each fiscal period. The value of the warrants is being adjusted in
each fiscal period until the revenue levels are attained and the warrants vest.
The exercise price of the warrants is the fair market value of the Company's
common stock on the date that the warrants vest.

    COST OF REVENUE.  Cost of revenue consists of direct product costs such as
standard parts and components for our products, salaries and employee benefits
for manufacturing personnel and overhead such as equipment and facility costs.

    GROSS PROFIT.  We expect our gross profit to be affected by many factors
including pricing, product mix, cost factors such as component prices, internal
and external manufacturing costs as well as manufacturing efficiencies due to
higher volume of product shipments which we believe will result in the
improvement of overhead absorption.

    RESEARCH AND DEVELOPMENT.  Research and development expenses consist
primarily of salaries and employee benefits for engineering personnel and costs
relating to prototypes including components, non-recurring engineering charges
and tools. Product enhancements and new features are key objectives. We expect
research and development expenses to increase in absolute dollars in the future.

    SALES AND MARKETING.  Sales and marketing expenses consist primarily of
salaries, employee benefits, trade shows, public relations, marketing materials,
travel and other marketing expenses. Future sales and

                            Page 9 of 23 Total Pages
<PAGE>
marketing activities will involve additional costs related to the expansion of
the sales and sales engineering organization, product branding, advertising and
public relations costs. We expect sales and marketing expenses to increase in
absolute dollars in the future.

    GENERAL AND ADMINISTRATIVE.  General and administrative expenses consist of
personnel costs for executive officers, administrative and support activities
including payroll administration, worker's compensation and general liability
insurance, accounting and finance, legal, tax, human resources and transaction
processing.

    STOCK COMPENSATION AND WARRANT CHARGES.  Stock options have been granted
with exercise prices that were less than the estimated fair value of the
Company's common stock. Compensation cost associated with these options is the
difference between the fair value of the stock and the exercise price.

    In consideration for entering into certain long-term reseller agreements,
the Company granted to the customers vested warrants to purchase 55,000 shares
of the Company's common stock at the market value of the Company's stock on the
dates the warrants were granted The value of the warrants was calculated by
applying the Black-Scholes option pricing model using the fair market value of
the Company's common stock on the date the agreements were executed. The value
of the warrants has been charged to expense as a component of stock compensation
and warrant charges in the condensed statement of operations.

    INCOME TAX EXPENSE.  Prior to our IPO, we had been included in Brooktrout's
consolidated income tax filings and these losses have been used to reduce the
group's taxes payable. Brooktrout has not and does not intend to reimburse us
for the value of the net losses used to reduce Brooktrout's consolidated taxable
income. Accordingly, we have not recorded any benefit related to these losses.
We are no longer to be included in Brooktrout's consolidated income tax filings;
we do not anticipate recognizing any benefits from losses generated in the short
term due to our limited operating history. We expect to continually evaluate the
recoverability of net loss carryforwards.

RESULTS OF OPERATIONS

THREE AND SIX MONTHS ENDED MARCH 31, 2000 AND 1999

    GROSS REVENUE.  Gross revenue for the three and six months ended March 31,
2000 was $4,003,000 and $7,155,000, compared to $327,000 and $391,000 for the
same three and six month period in fiscal year 1999, which represented increases
of $3,676,000 and $6,764,000, respectively. These increases are attributable to
the comparatively low level of revenue during the first six months in fiscal
1999. We recognized our first sale in the quarter ended December 31, 1998 after
our product successfully completed beta testing, and commenced commercial
operations and the general release of our products in February 1999.

    SALES DISCOUNT--WARRANTS.  During the three months ended March 31, 2000, the
Company recognized $439,000 of sales discounts related to warrants granted to
certain customers. Since these equipment purchase contracts were executed during
the three months ended March 31, 2000, no such sales discounts were recorded in
any prior fiscal periods.

    COST OF REVENUE.  Cost of revenue was $2,193,000 and $3,962,000, or
approximately 55% of gross revenue, for the three and six months ended
March 31, 2000, compared to $276,000 and $312,000 for the three and six months
ended March 31, 1999. The significantly higher cost of revenue in the fiscal
periods of 2000 is due to the increased revenue volume.

    GROSS PROFIT.  Gross profit on gross revenue was $1,810,000 and $3,193,000,
and gross profit percentage on gross revenue was approximately 45%, for the
three months and six months ended March 31, 2000, compared to gross profit of
$51,000 and $79,000 for the three and six months ended March 31, 2000. This
increases were due to the substantially greater revenue recognized during the
fiscal periods of 2000.

                           Page 10 of 23 Total Pages
<PAGE>
    RESEARCH AND DEVELOPMENT.  Research and development expenses increased by
approximately 70% and 49% to $1,940,000 and $3,592,000, respectively, during the
three months and six months ended March 31, 2000 from $1,139,000 and $2,412,000
for the three and six months ended March 31, 1999. These increases were due
primarily to increases in payroll related expenses from growth in the number of
engineering employees from year-to-year, and to significantly increased
consulting expenses for specific development projects during the three and six
months of fiscal 2000.

    SELLING, GENERAL AND ADMINISTRATIVE.  Selling, general and administrative
expenses for the three and six months ended March 31, 2000 were $2,304,000 and
$4,394,000, compared to $576,000 and $922,000 for the three and six months ended
December 31, 1998, which represented increases of $1,728,000 and $3,472,000,
respectively. These increases were due primarily to payroll-related expenses,
travel, advertising/marketing and trade show expenses associated with the
build-up in sales and marketing staff and activities, as well as expenses
relating to the implementation of internal Year 2000 compliant systems.

    STOCK COMPENSATION AND WARRANT CHARGES.  In prior periods, stock options
have been granted with exercise prices that were less than the estimated fair
value of our common stock. Compensation cost associated with such options was
determined as the difference between the fair value of the stock and the
exercise price. Stock compensation costs increased to $286,000 and $703,000 for
the three and six months ended March 31, 2000, from $62,000 and $94,000 for the
three and six months ended March 31, 2000, as the compensation cost is being
charged to expenses over the option vesting period.

    During the three months ended March 31, 2000, the Company recognized
$849,000 in warrant charges related to certain long-term reseller agreements.
Since the equipment purchase contracts containing the warrant grant provisions
were executed during the three months ended March 31, 2000, no such charges were
recorded in any prior fiscal periods.

    INCOME TAX EXPENSE.  Prior to our IPO, we had been included in Brooktrout's
consolidated income tax filings and the losses associated with the Company have
been used to reduce the group's taxes payable. Brooktrout has not and does not
intend to reimburse us for the value of the net losses used to reduce
Brooktrout's consolidated taxes. Accordingly, we have not recorded any benefit
related to these prior losses. We have not recognized any benefit in the current
quarter for the losses generated for the three and six months ended March 31,
2000 as we believe that it is more likely than not that such benefits will not
be recoverable. We will continually evaluate the recoverability of net loss
carryforwards.

    NET LOSS.  Net losses for the three and six months ended March 31, 2000 were
$3,852,000 and $6,398,000 compared to net losses of $1,726,000 and $3,349,000
for the three and six months ended March 31, 2000, which represented increases
of $2,126,000 and $3,049,000, respectively. These increased net losses are due
primarily to the increases in operating expenses, stock compensation and
warrant-related charges, as described above, that more than offset the increase
in gross profit from increased revenue resulting from the shipment of our
product during the three and six months ended March 31, 2000.

LIQUIDITY AND CAPITAL RESOURCES

    From inception through the IPO, our operations had been funded through
contributions of capital and loans from Brooktrout. Subsequent to the IPO, our
operations have been funded through the proceeds from the IPO.

    Cash decreased by $11,216,000 to $10,011,000 at March 31, 2000 from
$21,227,000 at September 30, 1999. The decrease in cash is due primarily to a
$4,309,000 increase in accounts receivable, a $1,464,000 increase in inventory,
and the net loss for the six months ended March 31, 2000 of $6,398,000.

    The increase in accounts receivable was due to substantially higher gross
revenue billings during the first six months of fiscal 2000, while the increase
in inventory was due to the expectation of increased

                           Page 11 of 23 Total Pages
<PAGE>
shipment volumes during subsequent quarters. For the six months ended March 31,
2000 and 1999, we purchased fixed assets of approximately $954,000 and $419,000,
respectively. We currently have no material commitments for additional capital
expenditures.

    We believe that the remaining net proceeds will be sufficient to meet our
anticipated cash needs for working capital and capital expenditures at least
until September 30, 2000. Thereafter, if cash generated from operations is
insufficient to satisfy our liquidity requirements, we may need to raise
additional funds through public or private financing, strategic relationships or
other arrangements. There can be no assurance that such additional funding, if
needed, will be available on terms that we believe are attractive, or at all. If
we fail to raise capital when needed, it could harm our business, operating
results and financial condition. If we raise additional funds through the
issuance of equity securities, the percentage ownership of our stockholders
would be reduced.

    We do not believe that inflation has had a significant effect on our
operations to date.

                                  RISK FACTORS

    YOU SHOULD CAREFULLY CONSIDER THE FOLLOWING RISK FACTORS AND THE OTHER
INFORMATION IN THIS QUARTERLY REPORT. OUR BUSINESS, FINANCIAL CONDITION OR
RESULTS OF OPERATIONS COULD BE HARMED BY ANY OF THE FOLLOWING RISKS.

WE HAVE A HISTORY OF LOSSES AND ANTICIPATE FUTURE LOSSES

    We have accumulated losses of approximately $22.2 million since inception in
October 1996 through March 31, 2000 and expect to incur net losses in the
future. Losses were approximately $10.5 million for the year ended
September 30, 1999 and approximately $6.4 million for the first six months of
fiscal 2000. We anticipate continuing to incur significant sales and marketing,
research and development and general and administrative expenses and, as a
result, we will need to generate higher revenues to achieve and sustain
profitability. We cannot be certain we will realize sufficient revenues to
achieve profitability.

BECAUSE OF OUR LIMITED OPERATING HISTORY IT IS DIFFICULT FOR US TO PREDICT
FUTURE RESULTS OF OPERATIONS

    We commenced operations in March 1997 and our first product became generally
available in February 1999. Due to our limited operating history, it is
difficult for us to predict future results of operations. You should consider
our business and prospects in light of the risks typically encountered by
companies in their early stages of development, particularly those in rapidly
evolving markets such as the data communications equipment market. We cannot be
certain that we will successfully address these risks.

OUR OPERATING RESULTS ARE LIKELY TO FLUCTUATE SIGNIFICANTLY AND CAUSE OUR STOCK
PRICE TO BE VOLATILE WHICH COULD CAUSE THE VALUE OF YOUR INVESTMENT IN OUR
COMPANY TO DECLINE

    Our quarterly or annual operating results are likely to fluctuate
significantly in the future due to a variety of factors, many of which are
outside of our control. If our operating results do not meet the expectations of
securities analysts, the trading price of our common stock could significantly
decline which may cause the value of your investment in our company to decline.
In addition, the value of your investment could be impacted by investor
perception of the Internet and emerging data communications sectors generally,
independent of the operating performance of our company or other similar
companies. Some of the factors that could affect our quarterly or annual
operating results or impact the market price of our common stock include:

    - our ability to develop, manufacture, market and support our products and
      product enhancements;

    - the timing and amount of, or cancellation or rescheduling of, orders for
      our products, particularly large orders from key customers;

    - our ability to retain key management, sales and marketing and engineering
      personnel;

    - announcements, new product introductions and price reductions in products
      offered by our competitors;

    - our ability to obtain sufficient supplies of sole or limited source
      components for our products;

    - a decrease in the average selling prices of our products;

    - changes in costs of components which we include in our products; and

    - the mix of products that we sell and the mix of distribution channels
      through which they are sold.

    Due to these and other factors, quarterly or annual revenues, expenses and
results of operations could vary significantly in the future, and
period-to-period comparisons should not be relied upon as indications of future
performance.

                           Page 13 of 23 Total Pages
<PAGE>
THE LOSS OF ANY SIGNIFICANT CUSTOMER COULD CAUSE OUR REVENUE TO DECLINE

    The loss of any of our significant customers could cause our revenue to
decline and thus have a material adverse effect on our business, financial
condition and results of operations. Our products became generally available in
February 1999 and to date we have only sold products to a limited number of
customers. Unless and until we diversify and expand our customer base, our
future success will significantly depend upon a limited number of customers.

FAILURE TO ADEQUATELY DEVELOP OUR SALES CHANNELS COULD CAUSE OUR REVENUE TO
DECLINE

    We sell our products directly through our sales force and indirectly through
original equipment manufacturers, value added resellers and system integrators.
Our failure to adequately develop these sales channels may cause our revenue to
decline and, thus, have a material adverse effect on our business, financial
condition and results of operations. We are currently continuing to develop
these sales channels and expect to expend significant resources in this area. As
of May 10, 2000, we had a total of 21 employees responsible for direct sales,
marketing and sales engineering in the United States and international markets.
To the extent we are able to enter into agreements with additional original
equipment manufacturers, value added resellers or systems integrators, the
amount and timing of resources which they devote to the sale of our products may
not be within our control, and they may not perform their obligations as
expected.

IF WE ARE UNABLE TO DEVELOP AND OPERATE AN EFFECTIVE CUSTOMER SUPPORT
ORGANIZATION, SALES OF OUR PRODUCTS MAY BE REDUCED

    Purchasers of data communications equipment assign significant weight in
their purchasing decisions to a vendor's capabilities and reputation in
supporting its products. We will be required to expend significant resources and
management attention on developing and operating a customer support
organization. If our level of customer support does not satisfy customer
expectations, our reputation and future sales could be adversely affected.
Accordingly, we have emphasized customer support in our business strategy and
marketing. Because our products were recently introduced for sale, we have
limited experience in operating a customer support program.

IF OUR TARGET CUSTOMERS DO NOT ACCEPT DSL TECHNOLOGY, WE MAY BE UNABLE TO
SUSTAIN OR GROW OUR BUSINESS

    Our future success is substantially dependent upon whether digital
subscriber line, or DSL, technology gains widespread market acceptance by data
communications service providers and the small to medium sized business users to
whom they market their services. In the event that our customers or potential
customers adopt technologies other than digital subscriber line, or DSL, we may
be unable to sustain or grow our business. Our business strategy and current
products are focused on DSL technology. Various alternative technologies,
including T-1, cable and broadband wireless, are currently available to deliver
high speed data communications, and each of the alternatives has comparative
advantages and disadvantages. Data communications service providers continually
evaluate alternative high speed data access technologies and may at any time
adopt technologies other than DSL.

IF OUR PRODUCTS ARE NOT ACCEPTED BY THE MARKET, OUR REVENUES MAY DECLINE

    We have recently introduced our products to the market. Market acceptance of
our products is critical to our future success. Factors that may affect the
market acceptance of our products include:

    - market acceptance of DSL technology;

    - the features, performance, price and total cost of ownership of our
      products;

    - the availability of competing products and technologies;

                           Page 14 of 23 Total Pages

    - the success and development of our direct sales force and distribution
      channels;

    - the quality of our customer service and support of our products; and

    - the breadth and depth of our product offerings.

    Failure of our existing or future products to achieve and maintain
meaningful levels of market acceptance would materially adversely affect our
business, financial condition and results of operations.

BECAUSE WE CURRENTLY DEPEND ON A SINGLE FAMILY OF PRODUCTS, ANY DECLINE IN
DEMAND FOR THOSE PRODUCTS MAY HARM OUR OPERATING RESULTS

    We expect to derive substantially all of our revenues from our DSL access
routers, or DSLARs, product family and related modules for the foreseeable
future. The market may not continue to demand our current products, and we may
not be successful in marketing any new or enhanced products. Any reduction in
the demand for our current products or our failure to successfully develop or
market and introduce new or enhanced products could materially adversely affect
our business, financial condition and results of operations.

UNLESS WE ARE ABLE TO KEEP PACE WITH THE EVOLUTION OF THE DATA COMMUNICATIONS
EQUIPMENT MARKET WE WILL NOT BE ABLE TO GROW OR SUSTAIN OUR BUSINESS

    The data communications equipment market is characterized by:

    - rapid technological advances;

    - evolving industry standards;

    - changes in end-user requirements;

    - frequent new product introductions; and

    - evolving offerings by data communications service providers.

    We believe our future success will depend, in part, on our ability to
anticipate or adapt to such changes and to offer, on a timely basis, products
that meet customer demands. We intend to continue to invest significantly in
product and technology development. The development of new or enhanced products
is a complex and uncertain process requiring the anticipation of technological
and market trends. We may experience design, manufacturing, marketing and other
difficulties that could delay or prevent our development, introduction or
marketing of new products and enhancements and result in unexpected expenses.
The introduction of new or enhanced products also requires that we manage the
transition from older products in order to minimize disruption in customer
ordering patterns and ensure that adequate supplies of new products can be
delivered to meet anticipated customer demand. Our inability to develop on a
timely basis new products or enhancements to existing products, or the failure
of such new products or enhancements to achieve market acceptance, could have a
material adverse effect our business, financial condition and results of
operations.

IF WE LOSE KEY PERSONNEL, WE MAY BE UNABLE TO SUCCESSFULLY OPERATE OUR BUSINESS

    Our success depends to a significant degree upon the continued contributions
of our principal management, engineering and sales personnel, many of whom
perform important management functions and would be difficult to replace. We do
not have employment contracts with our key personnel. The loss of the services
of any key personnel could materially adversely affect our business, financial
condition and results of operations.

<PAGE>
IF WE ARE UNABLE TO ATTRACT AND RETAIN ADDITIONAL QUALIFIED PERSONNEL, WE MAY BE
UNABLE TO SATISFY CUSTOMER DEMANDS WHICH MAY CAUSE OUR REVENUES TO DECLINE

    Our business strategy will require us to attract and retain additional
engineering, sales, customer support and administrative personnel. We have at
times experienced, and continue to experience, difficulty in recruiting
qualified personnel. Recruiting qualified personnel is an intensely competitive
and time consuming process. We may not be able to attract and retain the
necessary personnel to accomplish our business objectives, and we may experience
constraints that will adversely affect our ability to satisfy customer demand in
a timely fashion or to support our customers and operations. In addition,
companies in the data communications industry whose employees accept positions
with competitors frequently claim that such competitors have engaged in unfair
hiring practices. We could incur substantial costs in defending ourselves
against any such litigation, regardless of the merits or outcome of such
litigation.

FAILURE TO MANAGE OUR GROWTH EFFECTIVELY MAY PREVENT US FROM MAXIMIZING OUR
EARNINGS

    We have expanded and plan to continue to expand our operations, including
our sales and marketing activities, our accounting, billing and human resource
departments and the establishment of additional sales offices. This expansion
may place significant strains on our ability to manage our growth, including our
ability to monitor operations, bill customers, control costs and maintain
effective quality controls. Until the end of December 1999, we relied upon
Brooktrout, our parent company, to provide us with administrative and support
services, including accounting, human resources and computer systems. Since
then, we have implemented systems that provide the functions and services that
were previously provided by Brooktrout. If we fail to manage our growth
effectively, it could have a material adverse effect on our business, financial
condition and results of operations.

INTENSE COMPETITION IN THE MARKET FOR HIGH SPEED DATA ACCESS EQUIPMENT PREVENT
US FROM ACHIEVING OR SUSTAINING PROFITABILITY

    The market for data communications equipment is highly competitive,
particularly in the emerging DSL equipment market. If we are unable to compete
effectively in the market for high speed data access equipment, our results of
operations could be materially adversely affected. We compete directly with
Ascend Communications, Inc., which was acquired by Lucent Technologies Inc.;
Copper Mountain Networks, Inc.; Diamond Lane, which was acquired by
Nokia, Inc.; Paradyne Networks, Inc.; and Tut Systems, Inc. Many of our current
and potential competitors have significantly greater selling and marketing,
technical, manufacturing, financial, and other resources. Moreover, our
competitors may foresee the course of market developments more accurately than
we do and could in the future develop new technologies that compete with our
products. The strength and capabilities of our competitors may be increased as a
result of the trend toward consolidation in the data communications market.
Capitalizing on and maintaining our technological advantage will require a
continued high level of investment in research and development, marketing and
customer service and support. Due to the rapidly evolving markets in which we
compete, additional competitors with significant market presence and financial
resources may enter those markets, thereby further intensifying competition. We
may not have sufficient resources to continue to make the investments or achieve
the technological advances necessary to compete successfully with existing
competitors or new competitors.

IF WE ARE UNABLE TO DEVELOP INTERNATIONAL MARKETS FOR OUR PRODUCTS, WE MAY BE
UNABLE TO GROW AS PLANNED

    Our strategy emphasizes the development of international markets for our
products. We may be unsuccessful in marketing, selling and distributing our
products in foreign markets. Conducting business outside of the United States is
subject to risks, including:

    - longer accounts receivable collection cycles;

                           Page 16 of 23 Total Pages
<PAGE>
    - possible foreign currency exchange and conversion issues;

    - difficulties in managing operations across disparate geographic areas;

    - difficulties associated with enforcing agreements and collecting
      receivables through foreign legal systems;

    - changes in a specific country's or region's political or economic
      conditions;

    - trade protection measures;

    - import or export licensing requirements;

    - potential adverse tax consequences;

    - unexpected changes in regulatory requirements; and

    - reduced or limited protection of our intellectual property rights in some
      countries.

    We cannot be certain that one or more of such factors will not have a
material adverse effect on our future international operations, and
consequently, our business, financial condition and results of operations.

OUR DEPENDENCE ON SOLE AND SINGLE SOURCE SUPPLIERS AND INDEPENDENT MANUFACTURERS
EXPOSES US TO SUPPLY INTERRUPTIONS THAT COULD RESULT IN PRODUCT DELIVERY DELAYS

    Although we generally use standard parts and components for our products,
some key components are purchased from sole or single source vendors for which
alternative sources are not currently available. Our inability to obtain
sufficient quantities of these components may result in future delays or
reductions in product shipments which could materially adversely affect our
business, financial condition and results of operations. We currently purchase
proprietary components from Conexant and Motorola for which there are no direct
substitutes. These components could be replaced with alternatives from other
suppliers, but that would involve redesign of our products. Such redesign would
involve considerable time and expense. We currently enter into purchase orders
with our suppliers for materials based on forecasts, but have no guaranteed
supply arrangements with these suppliers.

    In addition, we currently use a small number of independent manufacturers to
manufacture printed circuit boards, chassis and subassemblies to our design. Our
reliance on independent manufacturers involves a number of risks, including the
potential for inadequate capacity, unavailability of, or interruptions in access
to, process technologies, and reduced control over delivery schedules,
manufacturing yields and costs. If our manufacturers are unable or unwilling to
continue manufacturing our components in required volumes, we will have to
transfer manufacturing to acceptable alternative manufacturers whom we have
identified, which could result in significant interruption of supply. Moreover,
the manufacture of these components is extremely complex, and our reliance on
the suppliers of these components exposes us to potential production
difficulties and quality variations, which could negatively impact cost and
timely delivery of our products. We currently enter into purchase orders with
independent manufacturers of materials based on forecasts, but have no
guaranteed arrangements with these manufacturers. Any significant interruption
in the supply, or degradation in the quality, of any component would have a
material adverse effect on our business, financial condition and results of
operations.

OUR LIMITED ABILITY TO PROTECT OUR INTELLECTUAL PROPERTY MAY PREVENT US FROM
RETAINING OUR COMPETITIVE ADVANTAGE

    Our success and our ability to compete are dependent, in part, upon our
proprietary technology. Taken as a whole, we believe our intellectual property
rights are significant 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 revenues. In
addition, the laws of many foreign

                           Page 17 of 23 Total Pages
<PAGE>
countries do not protect our intellectual property to the same extent as the
laws of the United States. Also, it may be possible for unauthorized third
parties to copy or reverse engineer aspects of our products, develop similar
technology independently or otherwise obtain and use information that we regard
as proprietary. 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 patents that we may obtain, or
to determine the validity and scope of the proprietary rights of others. Such
litigation could result in substantial costs and diversion of resources and
could have a material adverse effect on our future operating results.

INTELLECTUAL PROPERTY CLAIMS AGAINST US CAN BE COSTLY AND RESTRICT OUR BUSINESS

    The data communications industry is characterized by the existence of a
large number of patents and frequent litigation based on allegations of patent
infringement. As the number of entrants in our market increases and the
functionality of our products is enhanced and overlaps with the products of
other companies, we may become subject to claims of infringement or
misappropriation of the intellectual property rights of others. Any claims
asserting that our products infringe or may infringe proprietary rights of third
parties, if determined adversely to us, could have a material adverse effect on
our business, financial condition or results of operations. Any claims, with or
without merit, could be time-consuming, result in costly litigation, divert the
efforts of our technical and management personnel, cause product shipment delays
or require us to enter into royalty or licensing agreements, any of which could
have a material adverse effect upon our operating results. Legal action claiming
patent infringement may be commenced against us. We cannot assure you that we
would prevail in such litigation given the complex technical issues and inherent
uncertainties in patent litigation. In the event a claim against us was
successful, and we could not obtain a license to the relevant technology on
acceptable terms or license a substitute technology or redesign to avoid
infringement, this could have a material adverse effect on our business,
financial condition and results of operations.

CHANGES TO REGULATIONS AFFECTING THE TELECOMMUNICATIONS INDUSTRY COULD REDUCE
DEMAND FOR OUR PRODUCTS

    Any changes to the legal requirements relating to the telecommunications
industry, including the adoption of new regulations by federal or state
regulatory authorities under current laws or any legal challenges to existing
laws or regulations relating to the telecommunications industry, could have a
material adverse effect upon the market for our products. Moreover, our
distributors or customers may require, or we may otherwise deem it necessary or
advisable, that we modify our products to address actual or anticipated changes
in the regulatory environment. Our inability to modify our products or address
any regulatory changes could have a material adverse effect on our business,
financial condition or results of operations.

CONTROL BY BROOKTROUT MAY LIMIT STOCKHOLDERS' ABILITY TO INFLUENCE THE OUTCOME
OF MATTERS REQUIRING STOCKHOLDER APPROVAL

    At March 31, 2000, Brooktrout owned approximately 56% of the outstanding
shares of common stock. Accordingly, Brooktrout will be able to control or
significantly influence matters requiring approval by our stockholders,
including the election of directors and the approval of mergers or other
business combination transactions. This concentration of ownership could have
the effect of delaying or preventing a change in our control or otherwise
discouraging a potential acquiror from attempting to obtain control of us, which
in turn could have a material adverse effect on the market price of our common
stock or prevent our stockholders from realizing a premium over the market
prices for their shares of common stock.

                           Page 18 of 23 Total Pages
<PAGE>
SUBSTANTIAL FUTURE SALES OF OUR COMMON STOCK IN THE PUBLIC MARKET COULD CAUSE
OUR STOCK PRICE TO FALL

    The market price of our common stock could fall as a result of future sales
of a large number of shares of our common stock in the public market. As of
May 10, 2000, we had approximately 10,848,148 shares of common stock
outstanding, of which approximately 3,973,388 shares are freely transferable
without restriction or registration under the Securities Act of 1933, unless
such shares are held by our affiliates. The remaining 6,847,760 shares of common
stock held by existing stockholders and 247,070 shares subject to outstanding
options vested as of May 10, 2000, of which 170,234 shares will be restricted
securities and may only be sold in the public market if registered or if they
qualify for an exemption from registration under the Securities Act and 76,836
shares are freely transferable without restriction or registration under the
Securities Act of 1933. As of March 23, 2000, under specified circumstances and
subject to customary conditions, Brooktrout has the right, with respect to
6,075,000 shares of common stock, to require us to register its shares of common
stock under the Securities Act, and Brooktrout will have rights to participate
in any future registrations of securities by us.

PROVISIONS IN OUR CHARTER AND BYLAWS MAY DISCOURAGE TAKEOVER ATTEMPTS AND THUS
DEPRESS THE MARKET PRICE OF OUR COMMON STOCK

    Provisions in our amended and restated Certificate of Incorporation may have
the effect of delaying or preventing a change of control or changes in our
management. These provisions include:

    - the right of the Board of Directors, without stockholder approval, to
      issue shares of preferred stock and to establish the voting rights,
      preferences, and other terms thereof;

    - 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 prior
      stockholder approval;

    - the election of three classes of directors to each serve three year
      staggered terms;

    - the elimination of stockholder voting by consent;

    - the removal of directors only for cause;

    - the vesting of exclusive authority in the Board of Directors (except as
      otherwise required by law) to call special meetings of stockholders; and

    - certain advance notice requirements for stockholder proposals and
      nominations for election to the Board of Directors.

    These provisions discourage potential takeover attempts and could adversely
affect the market price of our common stock.

BECAUSE WE HAVE NO SPECIFIC PLAN FOR ANY SIGNIFICANT PORTION OF THE NET PROCEEDS
OF OUR IPO, OUR MANAGEMENT WILL HAVE THE DISCRETION TO ALLOCATE THE NET PROCEEDS
OF OUR IPO TO USES THE STOCKHOLDERS MAY NOT DEEM DESIRABLE

    Although we expect to use the net proceeds of our IPO for general corporate
purposes such as working capital, product development and sales and marketing,
we currently have no other specific plan for any significant portion of the net
proceeds of our IPO. As a consequence, our management will have the discretion
to allocate the net proceeds of our IPO to uses the stockholders may not deem
desirable. We may not be able to invest these net proceeds to yield a
significant return. Substantially all of the net proceeds of our IPO will be
invested in short-term, interest-bearing, investment grade securities or
guaranteed obligations of the U.S. government for an indefinite period of time.

                           Page 19 of 23 Total Pages
<PAGE>
WE DO NOT INTEND TO PAY DIVIDENDS

    To date, we have never declared or paid any cash dividends on shares of our
common stock. We currently intend to retain our earnings for future growth and
development of our business and, therefore, do not anticipate declaring or
paying any dividends in the foreseeable future.

ITEM 3.   QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK

    Market risk is the potential change in a financial instrument's value caused
by fluctuations in interest and currency exchange rates and equity and commodity
prices. Our operating activities expose us to many risks that are continually
monitored, evaluated, and managed. Proper management of these risks helps reduce
the likelihood of earnings volatility. At March 31, 2000, we were not a party to
any derivative arrangement and we do not engage in trading, market-making or
other speculative activities in the derivatives markets. We do not engage in
regular hedging activities to minimize the impact of foreign currency
fluctuations. At March 31, 2000, we had no short-term or long-term debt
obligations.

                               OTHER INFORMATION

ITEM 2. CHANGES IN SECURITIES AND USE OF PROCEEDS

(a) The Company completed its IPO in September 1999. The IPO was made pursuant
    to a registration statement on Form S-1, originally filed with the
    Securities and Exchange Commission on June 18, 1999, as amended (Commission
    File No. 333-81071), which was declared effective on September 23, 1999. The
    IPO commenced on September 24, 1999 and terminated shortly thereafter after
    the sale into the public market of all of the registered shares of common
    stock.

    The shares of common stock sold in the IPO were offered for sale by a
syndicate of underwriters represented by U.S. Bancorp Piper Jaffray, Warburg
Dillon Read LLC, Tucker Anthony Cleary Gull and DLJdirect Inc.

    The Company registered an aggregate of 3,500,000 shares of common stock
(including 1,500,000 sold by Brooktrout as a selling shareholder) in the IPO at
a per share price of $12.00, for an aggregate offering price of $42,000,000. As
of the date of the filing of this report, 3,925,000 registered shares (including
425,000 shares previously owned by Brooktrout that were sold upon the exercise
of the underwriters' overallotment option) have been sold at an aggregate
offering price of $47,100,000. Of the 3,925,000 shares sold in the IPO,
2,000,000 shares were registered for the Company's account.

    The Company incurred the following expenses in connection with the IPO:

<TABLE>
<S>                                                           <C>
Underwriting discounts and commissions......................  $1.68 million
Other expenses..............................................   1.53 million
                                                              -------------
Total expenses..............................................  $3.21 million
                                                              =============
</TABLE>

    After deducting the expenses set forth above, the Company received
$20,790,000 in net proceeds for the IPO. From the period commencing on
September 23, 1999 through March 31, 2000, the Company has used approximately
$11.2 million of the net proceeds, of which approximately $10.5 million was used
to fund operating activities including the net loss for the second fiscal
quarter of 2000, and approximately $950,000 which was used to purchase
equipment.

(b) Recent Sales of Unregistered Securities

    (1) In January 2000, the Company granted a warrant to purchase 50,000 shares
       of the common stock to a customer at an exercise price of $18.75 per
       share in reliance upon the exemption from registration under
       Section 4(a) of the Securities Act of 1933. The warrant can be exercised,
       subject to certain conditions, from January 27, 2001 through January 27,
       2005.

    (2) In February 2000, the Company granted a warrant to purchase 5,000 shares
       of the common stock to a customer at an exercise price of $21.25 per
       share in reliance upon the exemption from registration under
       Section 4(a) of the Securities Act of 1933. The warrant can be exercised,
       subject to certain conditions, from February 2, 2001 through February 2,
       2005.
