                O/2/MICRO INTERNATIONAL LIMITED AND SUBSIDIARIES

                   NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

1.   BASIS OF PRESENTATION

        The accompanying consolidated financial statements have been prepared by
the Company, without audit, pursuant to the rules and regulations of the
Securities and Exchange Commission and, in management's opinion, include all
adjustments, consisting only of normal recurring accruals necessary to fairly
present the resulting operations for the indicated periods. Certain information
and footnote disclosures normally included in financial statements prepared in
accordance with generally accepted accounting principles have been condensed or
omitted pursuant to such rules and regulations. Although the Company believes
that the disclosures are adequate to make the information presented not
misleading, it is suggested that these consolidated financial statements be read
in conjunction with the consolidated financial statements and the notes thereto
included in the Company's Form 20-F registration statement for the year ended
December 31, 2003.

2.   SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

        a. Use of estimates

        The preparation of financial statements in conformity with accounting
principles generally accepted in the United States of America requires
management to make estimates and assumptions that affect certain reported
amounts and disclosures. Accordingly, actual results could differ from those
estimates.

        b. Recent accounting pronouncements not yet adopted

        In January 2003, the Financial Accounting Standards Board ("FASB")
released Interpretation No. 46, "Consolidation of Variable Interest Entities"
("FIN 46") which requires that all primary beneficiaries of Variable Interest
Entities ("VIE") consolidate that entity. FIN 46 is effective immediately for
VIEs created after January 31, 2003 and to VIEs in which an enterprise obtains
an interest after that date. It applies in the first fiscal year or interim
period beginning after June 15, 2003 to VIEs in which an enterprise holds a
variable interest it acquired before February 1, 2003. In December 2003, the
FASB published a revision to FIN 46 ("FIN 46R") to clarify some of the
provisions of the interpretation and to defer the effective date of
implementation for certain entities. Under the guidance of FIN 46R, entities
that do not have interests in structures that are commonly referred to as
special purpose entities (SPE's) are required to apply the provisions of the
interpretation in financial statements for periods ending after March 14, 2004.
The Company does not have interests in special purpose entities and the adoption
of FIN 46R did not impact the Company's financial statements.

     will have a material adverse effect on its consolidated results of
     operations or financial condition.

     The Company, as a normal course of business, is a party to various
     litigation matters, legal proceedings and claims. These actions may be in
     various jurisdictions, and may involve patent protection and/or patent
     infringement. While the results of such litigations and claims cannot be
     predicted with certainty, the final outcome of such matters is not expected
     to have a material adverse effect on its consolidated financial position or
     results of operations. No assurance can be given, however, that these
     matters will be resolved without the Company becoming obligated to make
     payments or to pay other costs to the opposing parties, with the potential
     for having an adverse effect on the Company's financial position or its
     results of operations.

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

        The following information should be read in conjunction with the interim
financial statements and the notes thereto in Part I, Item 1 of this quarterly
report and with Operating and Financial Review and Prospects contained in the
Company's Annual Report on Form 20-F (the "Annual Report").

OVERVIEW

        We design, develop and market high performance mixed signal integrated
circuits for power management, power saving applications and computer security
applications. Our net sales have been derived primarily from the sale of
integrated circuit products to customers in the computer, consumer electronics,
industrial and communications markets.

        We utilize a "fabless" semiconductor business model, which means we
focus on designing, developing and marketing products, while having these
products manufactured by large independent semiconductor foundries. Because we
are a fabless semiconductor company, we do not need to invest significant
capital to manufacture semiconductor devices, and can take advantage of some of
the cost-efficiencies of third-party foundries. We place purchase orders with
third parties for specific quantities of packaged semiconductor devices or
wafers at set prices. We also use third parties to test and assemble our
products, which reduces the capital we need to invest in these activities.

RESULTS OF OPERATIONS

        Net Sales. Net sales for the three months ended March 31, 2004 were
$22.2 million, an increase of $2.9 million or 14.8% from $19.3 million for the
three months ended March 31, 2003. The increase in net sales reflects increased
unit shipments of our existing products as well as shipments of new products.

        Gross Profit. Gross profit for the three months ended March 31, 2004 was
$12.8 million, an increase of $1.8 million or 16.8% from $11.0 million for the
three months ended March 31, 2003. This increase in dollar amount was due to
increased sales of products. We expect that our gross profit as a percentage of
net sales will fluctuate in the future as a result of the stages of our products
in their life cycles, variations in our product mix, the timing of our product
introductions and specific product manufacturing costs.

        Research and Development Expenses. Research and development expenses for
the three months ended March 31, 2004 were $4.6 million, a decrease of $351,000
or 7.1% from $4.9 million for the three months ended March 31, 2003. This
decrease was primarily due to re-arrangement of several shuttle runs or shared
engineering test wafers.

        Selling, General and Administrative Expenses. Selling, general and
administrative expenses for the three months ended March 31, 2004 were $4.3
million, a decrease of $60,000 or 1.4% from $4.3 million for the three months
ended March 31, 2003. This decrease in absolute dollar amount was primarily due
to decreased expenses relating to intellectual property protection activities
offset by the hiring of additional personnel, traveling, and other expenses
associated with the hiring of additional personnel. We expect that selling,
general and administrative expenses will continue to increase in dollar amount
for the foreseeable future.

        Non-operating Income-net. Non-operating income-net for the three months
ended March 31, 2004 was $796,000, an increase of $565,000 from $231,000 for the
three months ended March 31, 2003, primarily reflecting an increase in gain on
sale of long-term investments and foreign exchange gain.

        Income Taxes. Income tax expenses for the three months ended March 31,
2004 was $566,000, an increase of $296,000 from $270,000 for the three months
ended March 31, 2003. The effective income tax rate for three months ended March
31, 2004 was 11.9% and 13.8% for the three months ended March 31, 2003. The
effective rate was lower for the three months ended March 31, 2004 primarily due
to the sales mix in different countries.

                                       12



        Our quarterly results of operations have fluctuated significantly in the
past and may continue to fluctuate in the future based on a number of factors,
not all of which are in our control. In particular, our results of operations
have fluctuated in the past due, among other things, to competitive pressures on
selling prices; the volume of product sales; the timing and cancellation of
customer orders; lengthy sales cycles; pricing concessions on volume sales;
changes in product mix; product pricing from foundries; our ability to develop,
introduce and market new products and technologies on a timely basis;
introduction of products and technologies by our competitors; and market
acceptance of our and our customers' products. Our results of operations may
also fluctuate in the future based on a number of factors, including but not
limited to, those listed above, general business conditions in the semiconductor
industry; general economic conditions; currency fluctuations; the availability
of foundry capacity and raw materials, and our ability to expand and implement
our sales and marketing programs. As a result of the foregoing factors, we
believe period to period comparisons are not necessarily meaningful and should
not be relied upon as indicative of future results.

LIQUIDITY AND CAPITAL RESOURCES

        On March 31, 2004, we had $149.1 million in total current assets,
including $59.9 million in cash and cash equivalents and $64.2 million in
short-term investments. Our operating activities provided $3.3 million cash
during the three months ended March 31, 2004. Additionally, our investing
activities used cash of $10.6 million in the three months ended March 31, 2004
and our financing activities provided cash of $657,000 in the three months ended
March 31, 2004. We expect our operating activities will continue to generate
additional cash but we expect to continue to deposit more cash in the Taiwan
courts for preliminary injunctions and provisional attachment actions. In May
2004, we purchased the 37,180 square foot building in Santa Clara, California
housing our California operations. The purchase price was approximately $4.6
million.

DISCLOSURE REGARDING FORWARD-LOOKING STATEMENTS

        This Form 6-K contains statements of a forward-looking nature. These
statements are made under the "safe harbor" provisions of the U.S. Private
Securities Litigation Reform Act of 1995. You can identify these forward-looking
statements by terminology such as "may," "will," "expects," "should," "could,"
"plans," "intends," "anticipates," "believes," "estimates," "predicts,"
"potential" or "continue" or the negative of these terms and other comparable
terminology. These forward-looking statements include statements relating to our
future gross profits, research and development expenses and selling, general and
administrative expenses. The forward-looking statements contained in this Form
6-K involve known and unknown risks, uncertainties and other factors that may
cause our or the industry's actual results, levels of activity, performance or
achievements to be materially different from the future results, levels of
activity, performance or achievements expressed or implied by these statements.
Such risks and uncertainties include the stages of our products in their life
cycles, variations in our product mix, the timing of our product introductions,
specific product manufacturing costs, increased competition, introduction of new
competing technologies and the increase of unexpected expenses. These factors
also include, among other things, those risks outlined in our filings with the
Securities and Exchange Commission, including our Annual Report, that could
cause actual results to differ materially from the results contemplated by the
forward-looking statements. We assume no obligation to update or revise any
forward-looking information, whether as a result of new information, future
events or otherwise.

ITEM 3. QUANTITATIVE AND QUALITATIVE DISCLOSURE ABOUT MARKET RISK

        Market risk is the risk of loss related to adverse changes in market
prices, including interest rates and foreign exchange rates, of financial
instruments. In the normal course of business, our financial position is
routinely subject to a variety of risks, including market risk associated with
interest rate movements and currency rate movements on non-U.S. dollar
denominated assets and liabilities, as well as collectibility of accounts
receivable.

        We regularly assess these financial instruments and their ability to
address market risk and have established policies and business practices to
protect against the adverse effects of these and other potential exposures.

                                       13



Interest Rate Risk

        Our major market risk exposure is changing interest rates. Our exposure
to market risk for changes in interest rates relates primarily to our
investments in US treasury bills, time deposits, government and corporate bonds.

        We maintain an investment portfolio consisting mainly of fixed income
securities. These securities are subject to interest rate risk and will fall in
value if market interest rates increase. If market rates were to increase
immediately and uniformly by 10.0% from the levels at March 31, 2004, the fair
value of the portfolio would decline by an immaterial amount. We presently
intend to treat our fixed income investments as available for sale, and
therefore we do not expect our operating results or cash flows to be affected to
any significant degree by the effect of a sudden short-term change in market
interest rate exposures. We did not purchase or hold any derivative financial
instruments for trading purposes.

        The table below provides information about our financial instruments
whose maturity dates are greater than three months as of March 31, 2004.

Foreign currency risk

        Fluctuations in exchange rates may adversely affect our financial
results. The functional currencies for our foreign subsidiaries are the local
currency. As a result, certain of our assets and liabilities, including certain
bank accounts, accounts receivable, restricted assets and accounts payable,
exist in non-U.S. dollar denominated currencies such as New Taiwan Dollar, which
are sensitive to foreign currency exchange rate fluctuations. As of March 31,
2004, we held approximately $15.3 million in government bonds, certificates of
deposits, time deposits and demand accounts denominated in New Taiwan Dollars.

        We have not engaged in hedging techniques designed to mitigate foreign
currency exposures and we may experience economic loss as a result of foreign
currency exchange fluctuations. In the three month period ended March 31, 2004,
we experienced gains of $222,000 due to foreign currency exchange fluctuations,
which are reflected in the results of operations
