NOTE 5.  RECENT ACCOUNTING PRONOUNCEMENTS

        In June 1997, the FASB issued SFAS No. 130, "Reporting Comprehensive
Income." This Statement establishes standards for reporting and displaying
comprehensive income and its components in the consolidated financial
statements. It does not, however, require a specific format for the statement,
but requires the Company to display an amount representing total comprehensive
income for the period in that financial statement. The Company is in the process
of determining its preferred format. This Statement is effective for fiscal
years beginning after December 15, 1997.



                                     - 6 -
<PAGE>   7

        In June 1997, the FASB issued SFAS No. 131, "Disclosures about Segments
of an Enterprise and Related Information." The Statement establishes standards
for the way public business enterprises are to report information about
operating segments in annual financial statements and requires those enterprises
to report selected information about operating segments in interim financial
reports issued to shareholders. This Statement is effective for financial
statements for the periods beginning after December 31, 1997. The Company does
not believe it has any separately reportable segments.

NOTE 6.  SUBSEQUENT EVENT

        Subsequent to the end of its June 30, 1997 quarter, the Company
developed and announced a plan to restructure its operations to reduce future
worldwide operating costs. The plan principally relates to a reduction in its
workforce by approximately 30% of its personnel. The plan is expected to be
implemented in the Company's fourth quarter ending September 30, 1997 which will
result in the recognition of approximately $800,000 in related expenses.



ITEM 2:  MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION 
         AND RESULTS OF OPERATIONS


RESULTS OF OPERATIONS:

        The Company's Common Stock price may be subject to significant
volatility. For any given quarter, a shortfall in the Company's announced
revenue or earnings from the levels expected by securities analysts could have
an immediate and adverse effect on the trading price of the Company's Common
Stock. The Company may not learn of, or be able to confirm, revenue or earnings
shortfalls until late in the quarter or following the end of the quarter. In
general, the Company participates in a very dynamic high technology industry
which can result in significant fluctuations in the Company's Common Stock price
at any time.

        Except for the historical information contained herein, the matters
discussed in this Form 10-Q are forward-looking statements within the meaning of
Section 21E of the Securities Exchange Act of 1934, as amended, and Section 27A
of the Securities Act of 1933, as amended, that involve risks and uncertainties,
including the rate of orders for the Company's products, the timely availability
and acceptance of new products, changes in management of the Company,
difficulties experienced by the Company with respect to hiring and retaining
qualified personnel, the impact of competitive products and pricing, the impact
of the Company's efforts to implement its evolving long-term strategy and the
other risks detailed below including, without limitation, the risks described in
the section labeled "Factors That May Affect Future Results," and the risks
described from time to time in the Company's other reports filed with the
Securities and Exchange Commission. The actual results that the Company achieves
may differ materially from any forward-looking projections due to such risks and
uncertainties. Words such as "believes," "anticipates," "expects," "future,"
"intends," and similar expressions are intended to identify forward-looking
statements but are not the exclusive means of identifying such statements.

FACTORS THAT MAY AFFECT FUTURE RESULTS

        Micronics Computers, Inc. operates in a rapidly changing environment
that involves a number of risks, some of which are beyond the Company's control.
The following discussion highlights some of those risks.

        The Company's operating results are subject to quarterly and other
fluctuations due to a variety of factors, including the volume and timing of
orders received, potential cancellation or rescheduling of orders, competitive
pressures, availability and cost of component parts and materials from the
Company's suppliers, the adequate forecasting of the mixed product demand due to
production lead times, the timing of new product announcements and introductions
by the Company or its competitors, changes in the mix of products sold, research
and development expenses associated with new product introductions, the timing
and level of development costs, market cyclical nature of the semiconductor
industry and economic conditions generally or in various geographic areas and
the Company's ability to develop new product features.


                                     - 7 -
<PAGE>   8

        In recent quarters, the Company has experienced declining net sales and
has incurred net losses as a result of competitive pressures and the effects of
the loss of and slowing order rate from its major OEM and government customers.
The Company's ability to reduce the trend of declining net sales, which have
yielded net losses, is dependent on several factors including increased order
rates for the Company's products, successful and timely development and market
acceptance of the Company's next generation products, the availability of
qualified sales and engineering personnel and successful competition with the
Company's competitors on a price, service and performance basis. Many of these
factors are not within the Company's control, and if order rates for the
Company's products fail to increase, if the Company's next generation products
are not successfully and timely developed and accepted by the Company's
customers, or if the Company cannot successfully compete with its competitors,
many of whom have substantially greater resources than the Company, the
Company's net sales will continue to decline. To the extent that the Company is
unable to offset such sales declines with cost reductions, recurring losses are
likely.

COMPARISON OF RESULTS

        NET SALES  Net sales were $22.3 million for the three months ended June
30, 1997, a decrease of 25% from $29.8 million for the similar period ended June
30, 1996. Net sales for the nine months ended June 30, 1997 totaled $82.7
million, down 37% from $130.6 million through last year's third quarter. The
decreases in the quarter and the nine month net sales between comparable periods
are principally attributable to lower sales to OEM and government markets.

        COST OF SALES/GROSS PROFIT  The Company's gross profit as a percentage 
of net sales was 9.4% and 12.4% for the third quarter of fiscal 1997 and the
third quarter of fiscal 1996, respectively. Gross profit margin percentage was
10.8% and 11.7% for the nine months ended June 30, 1997 and 1996, respectively.
The decline in gross profit margin is primarily the result of intensive price
competition and lower sales levels to cover the Company's manufacturing costs.

        OPERATING EXPENSES  Operating expenses for the third quarter of fiscal
1997 decreased 13% or $.8 million from the comparable quarter in fiscal 1996 and
were 13% or $2.2 million lower for the nine months ended June 30, 1997 compared
to the prior year period. Research and development and general and
administrative expenses decreased $.5 million for the three months ended June
30, 1997 to $2.8 million compared to $3.3 million for the comparable period
ended June 30, 1996 and decreased $2.4 million for the nine months ended June
30, 1997 to $7.9 million compared to $10.3 million for the nine months ended
June 30, 1996. Selling and marketing expenses also decreased $.2 million for the
three month period ended June 30, 1997 to $2.3 million from $2.5 million for the
comparable three month period but increased $.3 million to $7.0 million from
$6.7 million for the comparable nine month periods ended June 30, 1997 and June
30, 1996, respectively. The net operating expense reductions in the three and
nine month periods in fiscal year 1997 compared to fiscal year 1996 are due to
decreases in the number of employees mainly attributable to the consolidation of
Micronics and Orchid organizations offset by cost increases which are primarily
the result of expanding sales and marketing efforts in the distribution and
international sales channels.

        INTEREST AND OTHER INCOME AND EXPENSE  Interest income for the quarter
ended June 30, 1997 increased $104,000 or 37% compared to the prior year period
and increased $467,000 or 91% for the first nine months of fiscal 1997 compared
to the comparable prior year period due to higher invested balances. The Company
did not incur any interest expense for the three and nine months periods ended
June 30, 1997. Other expense for the nine months of fiscal year 1997 is
primarily loan fees on the $20 million line of credit signed by the Company in
September 1995.

        PROVISION FOR INCOME TAXES  The Company's estimated effective tax rate
was 0.0% and 41.0% for the nine months ended June 30, 1997 and 1996,
respectively. The provision for income taxes for each period was computed by
applying the estimated fiscal year effective tax rate (net federal and state
statutory rate as adjusted for various tax credits and the estimated tax effect
of certain permanent items) to income before income taxes for each period. At
September 30, 1996, the Company established a full valuation allowance against
its deferred tax assets, and the Company has recorded no additional benefit
associated with its losses.

        SUBSEQUENT EVENT  Subsequent to the end of its June 30, 1997 quarter,
the Company developed and announced a plan to restructure its operations to
reduce future worldwide operating costs. The plan principally relates to a
reduction in its workforce by approximately 30% of its personnel. The plan is
expected to be implemented in the Company's fourth quarter ending September 30,
1997 which will result in the recognition of approximately $800,000 in related
expenses.

LIQUIDITY AND CAPITAL RESOURCES:

        Working capital at June 30, 1997 was $33.8 million, down $4.0 million
from $37.8 million at September 30, 1996. The decrease in working capital was
primarily due to continued losses and a decrease in accounts receivable of $6.4
million offset by an increase of $3.3 million in inventories. Accounts
receivable decreased principally due to the lower sales in the quarter. The
increase in inventories was primarily related to a change in the inventory
management process by the Company's largest OEM customer, the impact of lower
sales and the effect of new product introductions.

        At June 30, 1997, the Company's principal sources of liquidity included
$22.7 million of cash and cash equivalents and short-term interest-bearing
financial instruments. The Company also has a secured line of credit of $20
million. The Company has provided notice to the lender of the Company's decision
to terminate this line of credit agreement as of September 11, 1997.

        Management believes existing cash and cash equivalents and short-term
investments will provide sufficient funds to meet the Company's operating and
capital requirements over the next twelve months provided the Company is able to
maintain or increase its sales levels.

FUTURE BUSINESS PLANS:

        The Company has and continues to work with its financial advisor to
identify attractive acquisition and strategic partner relationships. While
ongoing opportunities are being explored, the Company will not be in a position
to comment on any potential transaction until a binding agreement is reached,
if any, and it is appropriate under applicable securities laws to make a public
disclosure.
