A.  Basis of Presentation:
    ----------------------

    The accompanying condensed unaudited consolidated financial statements have
been prepared by Number Nine Visual Technology Corporation (the "Company") in
accordance with generally accepted accounting principles for interim financial
information and pursuant to the applicable rules and regulations of the
Securities and Exchange Commission.  The condensed unaudited consolidated
financial statements include the accounts of the Company, its foreign sales
corporation and its wholly-owned German subsidiary.  All material intercompany
accounts and transactions have been eliminated in consolidation.  In the opinion
of management, the accompanying financial statements contain all adjustments
(consisting of normal and recurring accruals) necessary to present fairly all
financial statements.  The financial statements herein should be read in
conjunction with the Company's consolidated financial statements and notes
thereto contained in the Company's Annual Report on Form 10-K for its fiscal
year ended December 28, 1996.  Operating results for the three and nine month
periods ended September 27, 1997 may not necessarily be indicative of the
results to be expected for any other interim period or for the full year.


B.  Cash and Cash Equivalents:
    --------------------------

    As of September 27, 1997, cash and cash equivalents were substantially
invested in the Company's operating account.  Additionally, the Company had cash
and cash equivalents invested in money market mutual funds comprised of
obligations which are issued or guaranteed as to principal and interest by the
U.S. government and thus constitute direct obligations of the United States of
America with a dollar-weighted average maturity of 90 days or less.

    The market for the Company's products is characterized by rapid
technological advances, frequent new product life cycles, product obsolescence,
changes in customer requirements, evolving industry standards, significant
competition and rapidly changing prices.

    The Company had a receivable of approximately $2.4 million outstanding at
September 27, 1997 due from a manufacturing contractor, related to components
sold by the Company at cost to the contractor for assembly into finished goods.

D.  Debt:
    -----

    The Company is party to an amended loan and security agreement with a
commercial bank providing for a revolving credit facility of $15 million.

    Pursuant to this agreement, the Company may borrow an amount equal to 65% of
qualified accounts receivable (as defined in the agreement) up to the maximum
amount at an interest rate per annum equal to either the prime rate (8.50% as of
September 27, 1997) plus 1% or at the Libor Rate (as defined in the agreement)
plus 2.5%, plus an unused line fee at a rate of 0.5% per annum on the unused
portion of the maximum borrowing amount.  The agreement expires on December 2,
1998 and is renewable on a yearly basis thereafter.  The loan balance is
collateralized by substantially all of the Company's assets, except for certain
fixed assets subordinated to the Company's long-term debt agreement.

    The agreement contains financial covenants including, but not limited to, a
minimum current ratio, minimum tangible net worth, a maximum debt to tangible
net worth ratio, and minimum quarterly net loss.  The agreement also gives the
lender the right to call the loan in the event of a material adverse change in
the Company's business and prohibits the Company from paying dividends without
the consent of the lender. The Company received a waiver from the lender for non
compliance with certain covenants in the agreement at the conclusions of the
first and second quarters of 1997 and is currently seeking a waiver at the
conclusion of the third quarter of 1997. The Company anticipates that it will
not be in compliance with certain covenants of the lender at the conclusion of
1997. If the Company is not in compliance with all of the covenants of the
lender, there can be no assurance that the lender will grant additional waivers
and/or amendments, nor can there be any assurance that alternative financing
will be available.


E.  Recently Issued Accounting Standard
    -----------------------------------

    In February 1997, The Financial Accounting Standards Board issued Statement
on Financial Accounting Standards No. 128, Earnings per Share (SFAS 128).  This
statement attempts to simplify current standards used in the United States for
computing earnings per share and make them more comparable with international
standards.  SFAS 128 replaces APB Opinion 15 and related interpretations (APB
15).  APB 15 requires the dual presentation of primary and fully diluted
earnings per share.  Primary EPS shows the amount of income attributed to each
share of common stock.  Fully diluted EPS considers common stock equivalents and
all other securities that could have been converted into common stock.

    SFAS 128 simplifies the computation of EPS by replacing the presentation of
primary EPS with a presentation of basic EPS.  Basic EPS includes no dilution
and is computed by dividing income available to common stockholders by the
weighted average number of common shares outstanding for the period.  Diluted
EPS reflects the potential dilution of securities that could share in the
earnings of an entity, similar to fully diluted EPS.  SFAS 128 is effective for
financial statements issued for periods ending after December 15, 1997,
including interim periods, and earlier application is not permitted.  SFAS 128
requires restatement of all prior period earnings per share data.

    Had the Company computed earnings per share consistent with the provisions
of SFAS 128 basic EPS would have been $(0.38) and $0.03 for the three month
periods and $(1.69) and $(1.01) for the nine month periods ended September 27,
1997 and September 28, 1996, respectively. Diluted EPS would have been
equivalent to the earnings per share amount reported.

F.  Income Taxes:
    -------------

    In the second quarter of 1997, the Company increased its valuation allowance
against the remainder of its net deferred tax asset, of approximately $1.8
million. Valuation of the net deferred tax asset was dependent upon generating
sufficient taxable income in near-term periods. Principally as a result of the
net losses incurred through the second quarter of 1997, management estimates of
future taxable income have been reduced. As a result, management believes it is
less likely than not that the remaining net deferred tax asset will be realized.


G.  Contingencies:
    --------------

    On June 11, 1996, a complaint was filed in the United States District Court
for the District of Massachusetts by named plaintiff RBI, an Alaskan limited
partnership, against the Company, Andrew Najda and  Stanley W. Bialek (the
"Selling Stockholders") and the managing underwriters of the Company's initial
public offering, Robertson, Stephens & Company, Cowen & Company and Unterberg
Harris (the "Managing Underwriters").  On or about July 17, 1996, a complaint
was filed in the United States District Court for the District of Massachusetts
by named plaintiff John Foley against the Company, each member of the Company's
Board of Directors, (Andrew Najda, Stanley W. Bialek, Dr. Fouad H. Nader and
William H. Thalheimer), former members of the Company's Board of Directors,
(Gill Cogan, Dr. Paul R. Low), Kevin M. Hanks, former Chief Financial Officer
and Treasurer of the Company, and the Managing Underwriters.  On or about
October 16, 1996, an additional complaint was filed in the United States
District Court for the District of Massachusetts by named plaintiff Robert
Schoenhofer against the Company, each member of the Company's Board of Directors
(during the period in question), Mr. Hanks, and the Managing Underwriters.  Each
of the plaintiffs purports to represent a class of purchasers of the Common
Stock of the Company between and including May 26, 1995 through January 31,
1996.  Each complaint alleges that the named defendants violated the Securities
Act of 1933 and the Securities Exchange Act of 1934 by, among other things,
issuing to the investing public false and misleading statements regarding the
Company's business, products, sales and earnings during the class period in
question.  The plaintiffs seek unspecified damages, interest, costs and fees.
By order of the District Court, these actions have been consolidated into a
single action.  It is possible that other claims may be made against the Company
or that there may be other consequences from the lawsuits.  The defendants deny
any liability, believe they have meritorious defenses, and intend to vigorously
defend these and any similar lawsuits that may be filed, although the ultimate
outcome of these matters cannot yet be determined.  If the lawsuits are not
resolved satisfactorily for the Company, there could be a material adverse
effect on the Company's future financial condition and results of operations
and, accordingly, income (loss).  The Company does not believe that the ultimate
liability, if any, is estimable or probable, and therefore no provision for any
liability that may result from the actions has been recognized in the
accompanying condensed consolidated financial statements.

                     MANAGEMENT'S DISCUSSION AND ANALYSIS
               OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS

"Management's Discussion and Analysis of Financial Condition and Results of
Operations" and other parts of this Form 10-Q contain forward-looking statements
involving risks and uncertainties as defined in the Private Securities
Litigation Reform Act of 1995.  The Company's actual results may differ
significantly from the results discussed in the forward-looking statements.
Factors that might cause such a difference include, but are not limited to,
those discussed here and included in the Company's publicly available filings
with the Securities and Exchange Commission, such as this report.

OVERVIEW

    Since its founding in 1982, Number Nine has introduced successive
generations of video/graphics subsystems providing advanced video/graphics
performance in desktop PCs. The Company has focused on providing a broad line of
high-performance hardware and software video/graphics solutions, targeting both
OEMs and two-tier and retail distribution customers. The Company's series of
128-bit proprietary accelerators have been recognized as some of the highest
performance graphics products available to the desktop PC market. During the
third quarter of 1997, the Company began shipping products utilizing its
third generation proprietary 128-bit graphics accelerator chip technology,
Ticket to Ride. Additionally, the Company began development of its fourth
generation 128-bit graphics accelerator chip technology. There can be no
assurance that the Company's new product, Revolution3D, utilizing the Ticket to
Ride chip will be successful or that the fourth generation product will be
completed and marketed successfully. The Company also markets Hawkeye95, a
display control utilities and driver software suite, which enhances user control
over various graphics functions and is designed to improve PC system graphics
performance under Windows95. In addition, the Company has begun to ship several
new video/graphics products, including the second generation of its Imagine 128
accelerator board for Apple PowerMac PCI computers, and the Imagine 128 Series 2
8MB H-VRAM, 3-D products targeted at the desktop PC games market, and next-
generation merchant accelerator chip based products in its Vision, Motion and
Reality product families. During 1997 and 1998, the Company currently plans to
develop several different products with 3-D capabilities and anticipates that
most of its products will also incorporate motion video acceleration.

    The Company's past operating results have been, and its future operating
results will continue to be, subject to fluctuations from quarter to quarter due
to a variety of factors, including: the gain or loss of significant customers;
changes in the mix of products sold and in the mix of sales by distribution
channels; the Company's ability to introduce new technologies and products on a
timely basis; availability and timing of component shipments and cost of
components obtained from the Company's suppliers; availability and cost of
manufacturing and foundry capacity; new product introductions by the Company's
competitors; delays in related product introductions by others; market
acceptance of the Company's products; product returns or price protection
charges from customers; reductions in sales of older generation products as
customers anticipate new products, giving rise to charges for obsolete or excess
inventory; and changes in product prices by the Company, its competitors and
suppliers, including possible decreases in unit average selling prices of the
Company's products caused by competitive pressures.  In particular, in the
second quarter of 1996, the Company identified charges of approximately $5.7
million of obsolete and excess finished goods and component inventory.  There
were a number of events during the second quarter of 1996 that were the primary
drivers for this provision.  These include an acceleration of product
transitions, further deterioration of memory inventory value, continued pressure
on pricing of older products, lower than expected sales activity of certain
products and excess component inventories.  Operating results can also be
adversely affected by general economic and other conditions affecting the timing
of customer orders, a downturn in the market for PCs, and order cancellations or
rescheduling.  The Company's sales to original equipment manufacturers ("OEMs"),
which accounted for 39.1% of net sales in the third quarter of 1997, 68.3% of
net sales in 1996, and 52.8% of net sales during 1995 are particularly
susceptible to fluctuations.

    The Company's sales to OEMs typically generate lower gross margins than
retail and distributor sales, but also generally entail lower marketing, sales
and product support costs.  The Company's net sales, gross margins and profits
have in the past, and may in the future, vary significantly depending on the
proportion of its sales to OEMs and other distribution channels, as well as the
mix of products sold in each channel.  The Company's sales of merchant-based
technology products are typically at a significantly lower margin than the 

                                       9
<PAGE>
 
sales of its proprietary technology products.  The gross margin on all of the
Company's products is significantly impacted by costs of components,
particularly memory costs, which have varied widely over the past several years.

RESULTS OF OPERATIONS FOR THE QUARTERS ENDED SEPTEMBER 27, 1997 AND SEPTEMBER
28, 1996

    Net Sales:  Net sales decreased approximately 61%, to $11.5 million in the
third quarter of 1997 from approximately $29.4 million in the third quarter of
1996. This decrease was primarily attributable to a decrease of net sales to the
Company's OEM customers, as well as significant pricing pressure on all of the
Company's products.  Sales to OEMs decreased 79%, to $4.5 million in the third
quarter of 1997 from approximately $21.8 million in the third quarter of 1996,
representing 39.1% of net sales in the third quarter of 1997 compared to 74.1%
in the third quarter of 1996. The decrease in OEM sales was primarily a result
of the discontinuation of sales of the Company's proprietary based 128-bit
products and merchant based products to Dell Computer Corporation ("Dell").
There were no sales to Dell in the third quarter of 1997 compared to 58.7% of
net sales in the third quarter of 1996. Net sales to domestic two-tier
distribution and retail customers decreased approximately 37% to approximately
$4.0 million in the third quarter of 1997 from approximately $6.3 million in the
third quarter of 1996. Total international sales decreased 52% to $3.2 million
in the third quarter of 1997 from $6.7 million in the third quarter of 1996.
Sales of the Company's proprietary based 128-bit products represented 82.6%, or
approximately $9.5 million, of net sales for the third quarter of 1997 compared
to 55.4%, or approximately $16.3 million, of net sales for the third quarter of
1996.

    Gross Margin: Gross profit decreased to $2.0 million in the third quarter of
1997 compared to gross profit of $5.7 million in the third quarter of 1996. This
decrease was primarily attributable to the reduction in net sales, particular
lower sales of the Company's proprietary products to its OEM customers, as well
as significant pricing pressure in the quarter on sales of older technology
products. The effects of planned new product introductions, anticipated stock
rotations and sales activity during future periods, as further described in
"Certain Factors That May Affect Future Results of Operations" may have a
negative impact on gross margin.

    Selling, General and Administrative Expenses:  Selling, general and
administrative expenses decreased 8%, to approximately $3.3 million in the third
quarter of 1997 from approximately $3.6 million in the third quarter of 1996,
primarily related to expense control of the Company's advertising and channel
promotion activities as compared to the 1996 period.  As a percentage of net
sales, selling, general and administrative expenses were 28.7% in the third
quarter of 1997 compared to 12.2% in the third quarter of 1996.  The Company
currently expects that total selling, general and administrative expenses will
decrease, although not necessarily as a percentage of net sales, primarily as a
result of additional expense controls and headcount reductions.

    Research and Development Expenses: Research and development expenses
increased approximately 29%, to approximately $2.2 million in the third quarter
of 1997 from approximately $1.7 million in the third quarter of 1996, resulting
primarily from increased staffing to support continued development of both
proprietary and merchant-based video/graphics products, as well as non-recurring
engineering expenses associated with the completion of the development effort of
the Company's Revolution3D products, based on the Company's third generation
128-bit graphics accelerator chip, Ticket-2-Ride, as well as associated graphic
boards utilizing this chip, such as Revolution 3D. During the third quarter of
1997, the Company continued the development of its next-generation, which is the
fourth generation, proprietary 128-bit graphics accelerator chip. As a
percentage of net sales, research and development expenses increased to 19.1% in
the third quarter of 1997 from 5.8% in the third quarter of 1996

    Interest Expense/Income: Interest expense for the third quarter of 1997 was
$46,000 compared to interest expense of $230,000 in the third quarter of 1996.
During the third quarter of 1997, the Company had lower average balances
outstanding against its revolving line of credit than during the third quarter
of 1996.

    Other Expense/Income:  Other income totaled $66,000 in the third quarter of
1997 compared to other income of $127,000 in the third quarter of 1996.  Other
income during the third quarters of 1997 and 1996 was primarily attributable to
interest earned on cash and cash equivalents.

                                       10
<PAGE>
 
    Provision (Benefit) for Income Taxes: In the second quarter of 1997, the
Company increased its valuation allowance against the remainder of its net
deferred tax asset, of approximately $1.8 million. Valuation of the net deferred
tax asset was dependent upon generating sufficient taxable income in near-term
periods. Principally as a result of the net losses incurred through the second
quarter of 1997, management estimates of future taxable income have been
reduced. As a result, management believes it is less likely than not that the
remaining net deferred tax asset will be realized.


RESULTS OF OPERATIONS FOR THE NINE MONTHS ENDED SEPTEMBER 27, 1997 AND SEPTEMBER
28, 1996

    Net Sales:  Net sales decreased 66%, to approximately $32.6 million in the
first nine months of 1997 from approximately $95.0 million in the first nine
months of 1996. This decrease was primarily attributable to a decrease in net
sales to the Company's OEM customers.  Sales to OEMs decreased 74%, to $16.6
million in the first nine months of 1997 from $63.4 million in the first nine
months of 1996, representing 50.9% of net sales in the first nine months of 1997
compared to 66.7% in the first nine months of 1996. The decrease in sales to
OEMs was primarily a result of discontinuation of the sales of the Company's
products to Dell during the second quarter of 1997.  Sales to Dell represented
approximately $4.9 million, or 15.0%, of net sales during the first nine months
of 1997 compared to $48.4 million, or 50.9%, of net sales during the first nine
months of 1996.  Total international sales decreased 50% to approximately $11.2
million in the first nine months of 1997 from approximately $22.6 million in the
first nine months of 1996.  Sales of the Company's proprietary based 128-bit
products represented approximately $24.6 million or 75.5% of net sales during
the first nine months of 1997, compared to $33.6 million or 35.4% during the
first nine months of 1996.

    Gross Margin:  Gross margin decreased 67%, to $3.2 million in the first nine
months of 1997 from $9.7 million in the first nine months of 1996.  This
decrease was primarily attributable to the reduction in net sales, particular
lower sales of the Company's proprietary products to its OEM customers, as well
as significant pricing pressure in the first nine months of 1997 on sales of
older technology products.  The effects of planned new product introductions,
anticipated stock rotations and sales activity during future periods, as further
described in "Certain Factors That May Affect Future Results of Operations" may
have a negative impact on gross margin.

    Selling, General and Administrative Expenses: Selling, general and
administrative expenses decreased 15%, to $10.5 million in the first nine months
of 1997 from $12.4 million in the first nine months of 1996, primarily as a
result of a reduction of advertising and channel promotion activities. As a
percentage of net sales, selling, general and administrative expenses were 32.2%
in the first nine months of 1997 compared to 13.1% in the first nine months of
1996. The Company currently expects that total selling, general and
administrative expenses will continue to decrease although not necessarily as a
percentage of net sales, primarily as a result of expense controls and headcount
reductions.

    Research and Development Expenses: Research and development expenses
increased 49%, to approximately $6.4 million in the first nine months of 1997
from $4.3 million in the first nine months of 1996, resulting primarily from
increased staffing to support continued development of both proprietary and
merchant based video/graphics products, lower capitalization of software costs,
as well as engineering nonrecurring expenses associated with the completion of
chip development of the Company's third generation proprietary based 128-bit
graphics accelerator product Revolution3D. During the first nine months of 1997,
the Company began the development of its next-generation, which is the fourth
generation, proprietary 128-bit chip, and continued development of some
additional products. As a percentage of net sales, research and development
expenses increased to 19.6% in the first nine months of 1997 from 4.5% in the
first nine months of 1996.

    Expenses Associated With Settlement With a Subcontractor:  During the first
nine months of 1996, the Company incurred a charge of approximately $2.0 million
related to the settlement of a dispute with one of its sub-contractors with
respect to the Company's commitment, if any, to purchase a quantity of DRAM
memory chips at prices significantly above the then current price levels.  As a
percentage of net sales, this settlement was 2.1% of net sales during the first
nine months of 1996.

    Interest Expense/Income:  Interest expense for the first nine months of 1997
was $229,000 compared to interest expense of $675,000 in the first nine months
of 1996. During the first nine months of 1997, the 

                                       11
<PAGE>
 
Company had lower average balances outstanding against its revolving line of
credit than during the first nine months of 1996.

    Other Expense/Income: Other income totaled $305,000 in the first nine months
of 1997 compared to other income of $338,000 in the first nine months of 1996.
Other income during the first nine months of 1997 and 1996 was primarily
attributable to interest earned on cash and cash equivalents; other income
during the first nine months of 1996 was primarily attributable to foreign
currency gains.

    Provision (Benefit) for Income Taxes: In the second quarter of 1997, the
Company increased its valuation allowance against the remainder of its net
deferred tax asset, of approximately $1.8 million. Valuation of the net deferred
tax asset was dependent upon generating sufficient taxable income in near-term
periods. Principally as a result of the net losses incurred through the second
quarter of 1997, management estimates of future taxable income have been
reduced. As a result, management believes it is less likely than not that the
remaining net deferred tax asset will be realized. For the nine months ending
September 29, 1996, the Company provided an additional income tax benefit of
$295,000 associated with the losses incurred during the period.


CERTAIN FACTORS THAT MAY AFFECT FUTURE RESULTS OF OPERATIONS

    This report contains forward-looking statements as that term is defined in
the Private Securities Litigation Reform Act of 1995.  Such statements are based
on management's current expectations and are subject to a number of factors and
uncertainties which could cause actual results to differ materially from those
described in the forward-looking statements.  The Company cautions investors
that there can be no assurance that actual results or business conditions will
not differ materially from those projected or suggested in such forward-looking
statements as a result of various factors, including but not limited to the
following:

    The Company is dependent on sole or limited source suppliers for certain key
components and has experienced limited availability, delays in shipments and
unanticipated cost fluctuations related to the supply of components,
particularly memory chips. The Company is actively working with memory component
suppliers to secure pricing and volume commitments for future production.
Additionally, the Company's suppliers could impact the availability of key
components, particularly memory and graphics accelerator chips, to the extent
that they reduce the Company's lines of credit and payment terms. In such an
event, the Company could have difficulty securing sufficient supply to meet
customer requirements. There can be no assurance that commitments will be
secured in sufficient amounts to meet the needs of the Company or at prices that
will enable the Company to attain profitability.

    The PC industry in general, and the market for the Company's products in
particular, are characterized by rapid technological advances, frequent new
product introductions, short product life cycles, product obsolescence, changes
in customer requirements or preferences for competing products, evolving
industry standards, significant competition, and rapidly changing pricing. In
this regard, the life cycle of products in the Company's markets is often as
short as six to twelve months. Therefore, the Company's future prospects will
depend in part on its ability to enhance the functionality of its existing
products in a timely manner and to continue to identify, develop and achieve
market acceptance of products that incorporate new technologies and standards
and meet evolving customer needs. There can be no assurance that the Company
will be successful in managing product transitions, including controlling
inventory of older generation products as new products are introduced. The
Company has in the past experienced and could in the future experience
reductions in sales of older generation products as customers anticipate new
product introductions. For example, the Company has completed its development
efforts on its Ticket to Ride 128-bit video/graphics accelerator chip, while its
second generation proprietary 128-bit video/graphics accelerator chip is nearing
the end of its product life cycle. The Company's ability to successfully
transition its Imagine 128 Series 2 products to its Revolution3D products, based
on its third generation proprietary-based 128-bit product, will depend on such
factors. While the Company reserves for anticipated returns based upon
historical rates of product returns and other factors, there can be no assurance
that reductions in sales and returns of older generation products by
distributors, which are primarily attributable to customer stock rotation, will
not give rise to charges for obsolete or excess inventory or substantial price
protection charges.

                                       12
<PAGE>
 
    The volume and timing of orders received during a particular quarter are
very difficult to forecast. The Company's customers can change delivery
schedules or cancel orders with limited or no penalties. For example, in
September 1996 the Company received notice from Dell that Dell would discontinue
buying its merchant graphics solution from the Company in the fourth quarter of
1996. In addition, during the first quarter of 1997, Dell reduced its purchases
of the Company's proprietary Imagine 128 Series 2 4MB VRAM product. As a result,
the Company does not expect that net sales to Dell during the remainder of 1997
will be significant. Future sales to Dell are uncertain and depend upon the
performance and pricing of new Company products and their acceptance by Dell.
Customers generally order on an as-needed basis, and as a result, the Company
has historically operated without significant backlog. Moreover, as is often the
case in the PC industry, a disproportionate percentage of the Company's net
sales in any quarter may be generated in the final month or weeks of a quarter.
Consequently, a shortfall in sales in any quarter as compared to management
expectations may not be identifiable until the end of the quarter. Because a
significant portion of operating expense levels are relatively fixed, the timing
of expense levels is based in large part on the Company's expectations of
future sales. As a result of the decline in net sales to the Company's OEM
customers, primarily Dell, and product transitions, the Company expects that net
sales will decline during the fourth quarter of 1997 compared to the fourth
quarter of 1996. If sales do not meet the Company's expectations, it may be
unable to quickly adjust spending, which could have a material adverse effect on
the Company's operating results.

    The Company's products have historically been based both on merchant and
proprietary-based video/graphic accelerator chips. The Company's contribution
from these product lines has been equally important during the last few years.
However, the Company believes that over the long-term, its proprietary-based
products will become an increasingly more important factor in determining
success for the Company. During 1996 and 1997 the Company's reliance on its
proprietary products has increased as a percentage of net sales and gross
profit. As a result, if sales of its proprietary-based products do not meet the
Company's expectations, or if the Company experiences delays in the completion
and availability of these proprietary-based products, it may be unable to
quickly develop merchant-based products, which could have a material adverse
effect on the Company's operating results.

    The Company has been served notice of three lawsuits seeking class action
status on or about June 11, 1996, July 16, 1996 and October 16, 1996,
respectively, filed in the United States District Court for the District of
Massachusetts naming as defendants the Company, the members of the Board of
Directors during the period in question, the former Chief Financial Officer and
Treasurer of the Company, and the Selling Shareholders and Managing Underwriters
of the Company's 1995 initial public offering. The alleged class of plaintiffs
consists of all persons who purchased shares of the Company's Common Stock on
the open market between and including May 26, 1995 through January 31, 1996. The
plaintiffs, who seek unspecified damages, interest, costs and fees, allege,
among other things, that the Company's Registration Statement and Prospectus in
its initial public offering and other public statements and reports filed with
the Securities and Exchange Commission during the class period in questions
contained false and materially misleading statements. The defendants deny
liability, believe they have meritorious defenses and intend to vigorously
defend against these and any similar lawsuits that may be filed, although the
ultimate outcome of these matters cannot yet be determined. If the lawsuits are
not resolved satisfactorily for the Company, there could be a material adverse
effect on the Company's future financial performance and results of operations
and accordingly, income (loss).

                                       13

    Due primarily to industry seasonality, demand for the Company's products
historically has been strongest during the fourth calendar quarter, and sales in
the subsequent calendar quarter have tended to decline. Net sales decreased
40.7% in the first quarter of 1997 from the fourth quarter of 1996, and 12.2% in
the first quarter of 1996 from the fourth quarter of 1995, although period-to-
period comparisons of financial results should not be relied upon as an
indication of future performance. Quarterly peaks in sales also tend to coincide
with peak working capital requirements.


LIQUIDITY AND CAPITAL RESOURCES

    Several factors in the development of the Company's business during 1995 and
1996 have had a significant impact on its balance sheet and cash flows. During
1995, the Company experienced significantly higher sales to two-tier and retail
distribution channel customers. These customers tend to order toward the end of
each quarter and to pay more slowly than OEM customers. The Company has since
shifted its emphasis, increasing its reliance on sales to its OEM customers. In
addition, the Company's manufacturing strategy has focused on purchasing a
higher proportion of components directly from manufacturers, which reduces
component costs but requires longer-term commitments and faster payment compared
to distributor suppliers. Finally, the fluctuating cost of memory components has
resulted in variable gross and operating margins, and limited availability at
times has required the use of cash when necessary to secure supplies of memory.
The Company incurred valuation adjustments for inventory during the fourth
quarter of 1995 and second quarter of 1996, and recorded charges to cost of
sales associated with obsolete and excess inventory of $8.0 million and $5.7
million, respectively. The Company determined that the market value for this
material was substantially less than the cost to procure and build, and the
Company has written down the components to estimated net realizable value less
selling costs. In combination, these factors resulted in the Company requiring
more working capital and generating less cash flow from operations than
anticipated.

   The Company continued to incur losses in 1997, revenue has dropped, and
marketplace pricing has increased. The Company's operating activities used cash
of approximately $5.0 million during the first nine months of 1997, compared to
operating activities which provided cash of approximately $8.4 million during
the first nine months of 1996. During the first nine months of 1997, net
decreases in accounts receivable, and inventories provided cash of approximately
$2.6 million and $5.7 million, respectively, which was offset by a net loss from
operations of approximately $15.4 million. Decreases in accounts receivable have
primarily been attributable to lower sales levels during the first nine months
of 1997. The Company believes it can operate with lower levels of working
capital relative to net sales and has committed additional resources to the
management and control of its receivables and inventories. At September 27,
1997, the Company's principal sources of liquidity consisted of approximately
$3.6 million of cash and cash equivalents and approximately $9.8 million
available under its revolving line of credit, pending approval of the debt
covenant waivers and subject to the Company receivables described below.

    During the first nine months of 1997, investing activities used cash of
approximately $2.1 million for purchases of computer and office equipment
compared to $2.1 million for purchases and office equipment and $466,000 of
capitalized software costs during the first nine months of 1996. Financing
activities used cash of approximately $3.2 million during the first nine months
of 1997, attributable to the reduction of the outstanding balance of the
revolving credit facility by $3.3 million. During the first nine months of 1996,
financing activities provided cash of $1.1 million, primarily attributable to
increasing the balance outstanding on the Company's revolving credit facility by
$666,000.

    As of September 27, 1997, approximately $5.2 million was outstanding under
the Company's revolving credit facility. The Agreement contains financial
covenants including, but not limited to, a minimum current ratio, minimum
tangible net worth, a maximum debt to tangible net worth ratio, and maximum
quarterly net loss. The Agreement also gives the lender the right to call the
loan in the event of a material adverse change in the Company's business and
prohibits the Company from paying dividends without the consent of the lender.
The Company has been out of compliance with certain terms of its Loan Agreement
from time to time and as a result has entered into amendments revising certain
covenants in such Agreement or has required a waiver from its lender. The
Company is seeking a waiver for noncompliance with certain covenants at the
conclusion of the third quarter of 1997, and as such remains out of compliance
with certain terms of its Loan Agreement. Should the lender grant a waiver for
such noncompliance at the conclusion of the third quarter of 1997, the Company
anticipates that it will require an additional waiver from its lender at the
conclusion of the fourth

                                       14
<PAGE>
 
quarter of 1997. Should the lender refuse to grant such a waiver or amendment,
and the line of credit is not available to the Company, management anticipates
that it would require alternative financing. However, if the Company is not able
to secure alternative financing, the Company's liquidity would be adversely
affected.

    The Company believes that its existing cash balances plus additional funds
currently expected to be generated from product sales and the existing bank debt
or alternative financing if available to the Company would be sufficient to fund
operations at current levels through the end of 1997. However, future growth in
sales, significant losses and limitations of credit/terms by suppliers, and/or
continued increases in working capital required by the Company's business would
result in the need for the Company to obtain additional equity or debt
financing. Additionally, the Company believes that working capital requirements
for future product releases, as well as continued investments in operations,
particularly research and development will require additional equity or debt
financing during 1998. As a result, the Company is exploring strategic and
financing alternatives. No assurances can be given that these funds will be
available to the Company on acceptable terms, if at all. The Company believes it
is prudent to evaluate opportunities to enhance its competitive position and
financing requirements in the technology marketplace.

PART II.  OTHER INFORMATION:
--------  ------------------


ITEM 1 - LEGAL PROCEEDINGS

    From time to time, the Company is involved in litigation relating to claims
arising out of its operation in the normal course of business.  Other than the
securities litigation discussed below, the Company is currently not a party to
any additional legal proceeding the adverse outcome of which, individually or in
the aggregate, management believes would have a material adverse effect on the
financial position or results of operations of the Company.

    On June 11, 1996, a complaint was filed in the United States District Court
for the District of Massachusetts by named plaintiff RBI, an Alaskan limited
partnership, against the Company, Andrew Najda and  Stanley W. Bialek (the
"Selling Stockholders") and the managing underwriters of the Company's initial
public offering, Robertson, Stephens & Company, Cowen & Company and Unterberg
Harris (the "Managing Underwriters").  On or about July 17, 1996, a complaint
was filed in the United States District Court for the District of Massachusetts
by named plaintiff John Foley against the Company, each member of the Company's
Board of Directors, (Andrew Najda, Stanley W. Bialek, , Dr. Fouad H. Nader and
William H. Thalheimer), former members of the Company's Board of Directors,
(Gill Cogan, Dr. Paul R. Low), Kevin M. Hanks, former Chief Financial Officer
and Treasurer of the Company, and the Managing Underwriters.  On or about
October 16, 1996, an additional complaint was filed in the United States
District Court for the District of Massachusetts by named plaintiff Robert
Schoenhofer against the Company, each member of the Company's Board of Directors
(during the period in question), Mr. Hanks, and the Managing Underwriters.  Each
of the plaintiffs purports to represent a class of purchasers of the Common
Stock of the Company between and including May 26, 1995 through January 31,
1996.  Each complaint alleges that the named defendants violated the Securities
Act of 1933 and the Securities Exchange Act of 1934 by, among other things,
issuing to the investing public false and misleading statements regarding the
Company's business, products, sales and earnings during the class period in
question.  The plaintiffs seek unspecified damages, interest, costs and fees.
By order of the District Court, these actions have been consolidated into a
single action.  It is possible that other claims may be made against the Company
or that there may be other consequences from the lawsuits.  The defendants deny
any liability, believe they have meritorious defenses, and intend to vigorously
defend these and any similar lawsuits that may be filed, although the ultimate
outcome of these matters cannot yet be determined.  If the lawsuits are not
resolved satisfactorily for the Company, there could be a material adverse
effect on the Company's future financial condition and results of operations
and, accordingly, income (loss).  The Company does not believe that the ultimate
liability, if any, is estimable or probable, and therefore no provision for any
liability that may result from the actions has been recognized in the
accompanying condensed consolidated financial statements.

    A foreign inventor has asserted claims against several PC manufacturers,
including customers of the Company, that the graphics technology included in
their systems infringes the inventor's patents.  Certain of the Company's
customers have notified the Company of these assertions and their intent to seek
indemnification from the Company in the event these claims are successful and
the infringing technology was included in products sold by the Company.  The
Company believes there are meritorious defenses to these claims and that if the
technology in fact infringes the inventor's rights, the Company would have
rights of indemnification from its suppliers.  While there can be no assurance,
the Company does not expect this matter to have a material adverse effect on the
Company.
