                         REPORT OF INDEPENDENT AUDITORS

To the Board of Directors and Shareholders of
United Microelectronics Corporation

We have audited the accompanying consolidated balance sheets of United
Microelectronics Corporation and subsidiaries as of December 31, 2001 and 2002
and June 30, 2003, and the related consolidated statements of operations,
changes in stockholders' equity and cash flows for the years ended December 31,
2000, 2001 and 2002 and for the six-month periods ended June 30, 2002 and 2003.
These financial statements are the responsibility of the Company's management.
Our responsibility is to express an opinion on these financial statements based
on our audits. We did not audit the financial statements of UMC Group (USA), a
wholly-owned subsidiary, and UMC Japan, a 52.00% owned subsidiary, whose
statements reflect total assets of NT$10,171 million and NT$25,759 million,
respectively, as of December 31, 2000, and total revenues of NT$43,491 million
and NT$10,542 million, respectively, for the year then ended. Those statements
were audited by other auditors whose reports have been furnished to us, and our
opinion, insofar as it relates to the amounts included for UMC Group (USA) and
UMC Japan, is based solely on the reports of the other auditors.

We conducted our audits in accordance with auditing standards generally accepted
in the United States. Those standards require that we plan and perform the
audits to obtain reasonable assurance about whether the financial statements are
free of material misstatement. An audit includes examining, on a test basis,
evidence supporting the amounts and disclosures in the financial statements. An
audit also includes assessing the accounting principles used and significant
estimates made by management, as well as evaluating the overall financial
statement presentation. We believe that our audits and the reports of the other
auditors provide a reasonable basis for our opinion.

In our opinion, based on our audits and the reports of other auditors, the
financial statements referred to above present fairly, in all material respects,
the consolidated financial position of United Microelectronics Corporation and
subsidiaries as of December 31, 2001 and 2002 and June 30, 2003 and the
consolidated results of their operations and their cash flows for the years
ended December 31, 2000, 2001 and 2002 and for the six-month periods ended June
30, 2002 and 2003, in conformity with the "Guidelines Governing the Preparation
of Financial Reports by Securities Issuers" and accounting principles generally
accepted in the Republic of China.

Accounting principles generally accepted in the Republic of China vary in
certain significant respects from accounting principles generally accepted in
the United States. The application of accounting principles generally accepted
in the United States would have affected the consolidated stockholders' equity
and financial position as of December 31, 2001 and 2002 and June 30, 2003, and
the consolidated results of operations for the years ended December 31, 2000,
2001 and 2002 and for the six-month periods ended June 30, 2002 and 2003, to the
extent summarized in Note 30 to the consolidated financial statements.

1. History and Organization

   United Microelectronics Corporation ("the Company") was incorporated in May
   1980 and commenced operations in April 1982. The Company's major business
   activity is providing dedicated semiconductor wafer foundry services. The
   Company provides a variety of services to fit individual customer's needs,
   including intellectual property, embedded IC design, design verification,
   mask tooling, wafer fabrication, and testing. The Company's common shares
   were publicly listed on the Taiwan Stock Exchange in July 1985 and its
   American Depositary Shares ("ADSs") were listed on the New York Stock
   Exchange in September 2000.

   United Microelectronics Corporation, United Integrated Circuits Corporation
   ("United Integrated Circuits"), United Silicon Incorporated ("United
   Silicon"), United Semiconductor Corporation ("United Semiconductor") and UTEK
   Semiconductor Corporation ("UTEK Semiconductor") were merged into one
   publicly traded entity, United Microelectronics Corporation, on January 3,
   2000.

2. Summary of Significant Accounting Policies

   The financial statements were prepared in conformity with "Guidelines
   Governing the Preparation of Financial Reports by Securities Issuers" and
   accounting principles generally accepted in the Republic of China. Summary of
   significant accounting polices is as follows:

   Principles of Consolidation

   The consolidated financial statements include the accounts of the Company and
   certain majority owned (50% or more) subsidiaries (hereinafter referred to
   collectively as "the Group") in accordance with the requirements of ROC
   Statement of Financial Accounting Standard ("ROC SFAS") No.7 and the
   regulations of the Taiwan Securities and Futures Commission ("Taiwan SFC").
   All intercompany accounts and transactions have been eliminated in the
   consolidated financial statements.

   Pursuant to ROC SFAS NO.7 and the regulations of the Taiwan SFC, if the total
   assets and operating revenues of a subsidiary are less than 10% of the
   non-consolidated total assets and operating revenues of the Company,
   respectively, the subsidiary's financial statements may, at the option of the
   Company, not be consolidated. Irrespective of the above test, when the total
   combined assets or operating revenues of all such non-consolidated
   subsidiaries constitute up to 30% of the Company's non-consolidated total
   assets or operating revenues, then each individual subsidiary with total
   assets or operating revenues up to 3% of the Company's non-consolidated total
   assets or operating revenues has to be included in the consolidation. Such
   subsidiaries are included in the consolidated financial statements
   thereafter, unless the percentage of the combined total assets or operating
   revenues for all such subsidiaries becomes less than 20% of the Company's
   respective unconsolidated amount.

Use of Estimates

The preparation of financial statements in conformity with generally accepted
accounting principles requires management to make estimates and assumptions that
affect the amounts of assets and liabilities, the disclosure of contingent
assets and liabilities at the date of the financial statements and the reported
amounts of revenues and expenses during the reported period. Actual results
could differ significantly from those estimates.

Certain Risks and Uncertainties

The Group is engaged in the foundry business of manufacturing semiconductor
products and sells its products primarily in Taiwan, Asia, North America and
Europe, generally without requiring collateral. The Group's products are
concentrated in the semiconductor industry, which is highly competitive and
rapidly changing, and its inventories are subject to rapid technological
obsolescence. While the Group has programs to minimize the required inventories
on hand and considers technological obsolescence in estimating required
allowances to reduce amounts to fair market value, such estimates could change
in the future. Significant technological changes in the industry could affect
operating results adversely.

             NOTES TO CONSOLIDATED FINANCIAL STATEMENTS-(Continued)

Translation of Foreign Currency Transactions

The accounts of the Company are maintained in New Taiwan dollars, the functional
currency. Transactions denominated in foreign currencies are translated into New
Taiwan dollars at the exchange rates prevailing on the transaction dates.
Receivables, other monetary assets, and liabilities denominated in foreign
currencies are translated into New Taiwan dollars at the exchange rates
prevailing at the balance sheet date. Exchange gains or losses are included in
the current year's results. The financial statements of foreign subsidiaries and
investees are translated into New Taiwan dollars using the spot rates as of each
financial statement date for asset and liability accounts, average exchange
rates for profit and loss accounts and historical exchange rates for equity
accounts. The cumulative translation effects for subsidiaries and investees
using functional currencies other than the New Taiwan dollars are included in
the cumulative translation adjustment in stockholders' equity.

Convenience Translation into US Dollars

The Company prepares its financial statements in New Taiwan ("NT") dollars, its
reporting currency. The United States ("US") dollar amounts disclosed in the
financial statements as of December 31, 2002 and June 30, 2003, respectively,
are presented solely for the convenience of the readers and were translated at
the Federal Reserve Bank of New York noon buying rate of NT$34.61 to US$1.00 in
effect on June 30, 2003. Such translation amounts are unaudited and it should
not be construed that the NT dollar amounts represent, or have been, or could
be, converted into US dollars at that or any other rate.

Cash Equivalents

Cash equivalents are short-term, highly liquid investments that are readily
convertible to known amounts of cash and with maturity dates that do not present
significant risks on changes in value resulting from changes in interest rates.

Marketable Securities

Marketable securities are recorded at cost when acquired and are stated at the
lower of aggregate cost or market value at the balance sheet date. The market
value of listed debt and equity securities, or closed-end funds is determined by
the average closing price during the last month of the fiscal year. The market
value for open-end funds is determined by their equity per unit at the balance
sheet date. The amount by which aggregate cost exceeds market value is reported
as a loss in the current year. In subsequent periods, recoveries of market value
are recognized as a gain to the extent that the market value does not exceed the
original aggregate cost of the investment.

             NOTES TO CONSOLIDATED FINANCIAL STATEMENTS-(Continued)

      Allowance for Doubtful Accounts

      The allowance for doubtful accounts is provided based on management's
      judgment and on the evaluation of collectibility and aging analysis of
      accounts and other receivables.

      Inventories

      Inventories are accounted for on a perpetual basis and recorded at cost
      when acquired and stated at the lower of aggregate cost, based on the
      weighted average method, or market value at the balance sheet date. The
      market values of raw materials and supplies are determined on the basis of
      replacement cost while the work in process and finished goods are
      determined by net realizable values. An allowance for loss on decline in
      market value and obsolescence is provided, when necessary.

      Long-term Investments

      Long-term investments are recorded at cost when acquired. Investments
      acquired by contribution of technological know-how are credited to
      deferred credits among affiliates, which will be amortized to income over
      a period of five years.

      Investments in less than 20% owned listed companies where significant
      influence on operational decisions of the investees does not reside with
      the Group, are accounted for by the lower of aggregate cost or market
      value method. The unrealized loss resulting from the decline in market
      value of investments that are held for long-term investment purposes is
      deducted from the stockholders' equity. The market value is determined by
      the average closing price during the last month of the fiscal year. The
      Group's investments in less than 20% owned unlisted companies are
      accounted for under the cost method. Impairment losses for the investees
      will be recognized if an other than temporary impairment is evident and
      the book value after recognizing the losses shall be treated as a new cost
      basis of such investment.

      Investment income or loss from investments in both listed and unlisted
      companies is accounted for under the equity method provided that the Group
      owns at least 20% of the outstanding voting shares of the investees and
      has significant influence on operational decisions of the investees. The
      difference of the acquisition cost and the underlying equity in the
      investee's net assets is amortized over five years.

                                      F-16



              UNITED MICROELECTRONICS CORPORATION AND SUBSIDIARIES
             NOTES TO CONSOLIDATED FINANCIAL STATEMENTS-(Continued)

      Unrealized intercompany gains and losses arisen from transactions with
      equity investees are eliminated in proportion to the Group's ownership
      percentage while those from transactions with majority-owned subsidiaries
      are eliminated entirely in consolidation. Profit from sales of depreciable
      assets between the investee and the Company is amortized and recognized
      based on the assets' economic service lives. Profit from other types of
      intercompany transactions is recognized when realized. The increase in the
      Group's proportionate share in the net assets of its investee resulting
      from its subscription to additional shares of stock, issued by such
      investee, at the rate not proportionate to its existing equity ownership
      in such investee, is credited to a capital reserve account. Any decrease
      in the Group's proportionate share in the net assets of the investee is
      debited against the existing balance of the similar capital reserve
      account, where the credit balance can only be offset to zero. If any
      excess amount exists, it will be debited against unappropriated retained
      earnings.

      Property, Plant and Equipment

      Property, plant and equipment are stated at cost. Interest incurred on
      loans used to finance the construction of property, plant and equipment is
      capitalized and depreciated accordingly.

      Depreciation is provided on the straight-line basis using the economic
      service lives of the assets less any salvage value. When the economic
      service lives are completed, property, plant and equipment, which are
      still in use, are depreciated over the newly estimated remaining useful
      lives of the salvage value. The economic service lives of the property,
      plant and equipment are as follows: buildings - 3 to 55 years; machinery
      and equipment - 5 years; transportation equipment - 2 to 5 years;
      furniture and fixtures - 2 to 20 years; leased assets and leasehold
      improvements - the lease period, or economic service lives, whichever is
      shorter.

      Maintenance and repairs are charged to expense as incurred. Significant
      renewals and improvements are treated as capital expenditures and are
      depreciated accordingly. When property, plant and equipment are disposed
      of, their original cost and accumulated depreciation are written off and
      the related gain or loss is included as non-operating income or expenses.

      Deferred Charges

      Deferred charges are stated at cost and amortized on a straight-line basis
      as follows: intellectual property and technology license fee - the term of
      contract or economic lives of the related technology; software - 2 to 5
      years; facilities use rights - 15 years; bonds issuance costs - over the
      life of the bonds; patents - over economic service lives; and acquired
      technological know-how - over the estimated useful life of the know-how.

              UNITED MICROELECTRONICS CORPORATION AND SUBSIDIARIES
             NOTES TO CONSOLIDATED FINANCIAL STATEMENTS-(Continued)

      At each balance sheet date, the Group assesses whether there is any
      indication of impairment other than temporary. If any such indication
      exists, the recoverable amount is estimated and provision for impairment
      losses is provided accordingly.

      Convertible and Exchangeable Bonds

      The excess of the stated redemption price over the par value is accrued as
      compensation interest payable over the redemption period, using the
      effective interest method.

      When convertible bondholders exercise their conversion rights, the book
      value of bonds is credited to common stock at an amount equal to the par
      value of the common stock and the excess is credited to capital reserve;
      no gain or loss is recognized on bond conversion.

      When exchangeable bondholders exercise their rights to exchange for the
      reference shares, the book value of bonds is to be offset with the book
      value of the investment in reference shares and the related stockholder's
      equities accounts, with the difference recognized as gain or loss on
      disposal of investments.

      Pension Plan

      The Group has funded defined benefit pension plans covering regular
      employees and the pension fund is managed by independently administered
      pension fund associations. The net pension cost is computed based on an
      actuarial valuation in accordance with the provision of ROC SFAS No. 18,
      which requires consideration of pension cost components such as service
      cost, interest cost, expected return on plan assets and amortization of
      net obligation at transition.

      Capital Reserve

      The following shall accrue as capital reserve: (1) any premiums on capital
      stock; (2) the net appraisal surplus of each fiscal year; (3) any gain on
      disposal of assets (not applicable for 2001 and after); (4) the fair
      market value of assets received from a merged company in excess of assumed
      liabilities and payment for shares held by shareholders of the merged
      company; (5) any donated surplus; and (6) change in an equity investee's
      capital structure. Capital reserve shall be exclusively used to cover
      accumulated deficits when the legal reserve is insufficient to cover the
      deficits or distribution of stock dividends.

      Treasury Stock

      The Group adopted the ROC SFAS No. 30, which requires that treasury stock
      held by the companies themselves be accounted for under the cost method.
      Cost of treasury stock is shown as a deduction to stockholders' equity,
      while gain or loss of selling treasury stock is treated as an adjustment
      to capital reserves.

      The Company's stock held by its subsidiaries is also treated as treasury
      stock in the Company's stand-alone account since January 1, 2002.

      Revenue Recognition

      Revenue is recognized when title and liability for risk of loss or damage
      to the products have been transferred to customers usually upon shipment.
      Sales returns and discounts taking into consideration customers' complaint
      and past experience are accrued in the same year of sales. The connected
      cost is to be deducted from the total cost of goods sold.

      Capital Expenditures versus Operating Expenses

      An expenditure is treated as an asset when it is probable that future
      economic benefits associated with the expenditure will flow to the Group
      and the total amount exceeds certain level. Otherwise it is charged to
      expense as incurred.

      Research and Development

      Costs incurred by the Group in research and development activities are
      expensed as incurred.

      Derivative Financial Instruments

      Hedging instruments are accounted for on a net accrual basis in accordance
      with the contractual interest rate or foreign exchange rate. Other
      derivative instruments are carried at fair value on the balance sheet date
      with any changes in unrealized gain or loss charged or credited to
      earnings for the year.

      Minority Interests

      Minority interests in the statement of operations includes interest in the
      earnings or losses of less than wholly-owned subsidiaries and the
      pre-acquisition earnings or losses of companies acquired during the year
      that the Group was not entitled to recognize.

      Income Tax

      The Group adopted the ROC SFAS No. 22 "Accounting for Income Taxes" for
      inter-period and intra-period income tax allocation. Provision for income
      tax includes deferred tax resulting from temporary differences and
      investment tax credits. Deferred tax assets and liabilities are recognized
      for the expected tax consequences of temporary differences between the tax
      bases of assets and liabilities and their reported amounts in the
      financial statements using enacted tax rates and laws that will be in
      effect when the difference is expected to reverse. Valuation allowance on
      deferred tax assets is provided to the extent that it is more likely than
      not that the tax benefits will not be realized.

      Income taxes (10%) on unappropriated earnings are recorded as expenses in
      the year when the shareholders have resolved that the earnings shall be
      retained.

      According to the ROC SFAS No. 12, the Group recognized the tax benefit
      from the tax credit incurred at the year equipment acquired, or the year
      the expenditure arises from research and development.

      Earnings per Share

      Earnings per share is calculated according to the ROC SFAS No.24. Basic
      earnings per share is computed by dividing net income (loss) by weighted
      average number of shares outstanding during the year. Diluted earnings per
      share is calculated by taking basic earnings per share into consideration
      plus additional common shares that would have been outstanding if the
      dilutive share equivalents had been issued. The net income (loss) would
      also be adjusted for the interest derived from any underlying dilutive
      share equivalents. The weighted-average outstanding shares are restated
      for stock dividends and bonus share issues.

3. Accounting Changes

   On September 1, 2001, UNIPAC Optoelectronics Corp. ("UNIPAC") was merged into
   Acer Display Technology Inc. which was the surviving corporate entity and was
   renamed AU Optronics Corp. As the Group has lost its significant influence
   over the investee, the investment was then accounted for under the lower of
   cost or market value method. Similarly, upon the listing of MediaTek
   Incorporation on the Taiwan Stock Exchange in 2001, the Group lost its
   significant influence over MediaTek and therefore, the investment in MediaTek
   was accounted for under the lower of cost or market value method since then.
   Prior to these transactions, the Group's investments in UNIPAC and MediaTek
   Incorporation were accounted for by equity method.

   Prior to January 1, 2002, treasury stock held by the Company's subsidiaries
   was accounted for in the consolidation level only. Since
   January 1, 2002, the Company has adopted ROC SFAS No. 30 to further include
   the Company's stock held by its subsidiaries as treasury stock in the
   Company's stand-alone account. This adoption has decreased the amount of
   long-term investment and stockholder's equity in the consolidated balance
   sheet by NT$172 million, respectively, representing the treasury stock held
   by an unconsolidated subsidiary. The net impact caused by the accounting
   changes is considered insignificant.

   During the six-month period ended June 30, 2003, the Company has acquired
   additional interests in Silicon Integrated Systems Corp., an investee
   acquired and accounted for under the lower of cost or market value method in
   December 2002, and was able to exercise significant influence over the
   investee since January 2003. As a result, the investment was accounted for
   under the equity method since then.

   Credit-linked deposits and repackage bonds were included in "cash and cash
   equivalents" and "long-term investments" respectively in 2002. However,
   during the six-month period ended June 30, 2003, the Taiwan SFC has amended
   its "Guidelines Governing the Preparation of Financial Reports by Securities
   Issuers" and defined a new account "other financial assets". As the
   credit-linked deposits and repackage bonds fall within the definition of this
   new account, they are now classified as "other financial assets" in
   accordance with the amended regulations and the comparatives were
   reclassified to conform to the new presentation.

             NOTES TO CONSOLIDATED FINANCIAL STATEMENTS-(Continued)


Note A: Investment in UniMicron Technology Corp. was previously accounted for
        under the equity method. As of October 31, 2001, UniMicron Technology
        Corp. was merged into World Wiser Electronics Incorporated which is the
        surviving corporate entity and renamed as Unimicron Technology Corp.


Note B: Significant influences were exercised by the Group over the investees,
        therefore, equity method applied.

Note C: As the Group was not able to exercise significant influences over the
        investees, the investments were accounted for under the cost method.

Note D: Starting from the third quarter of 2001, the Group was unable to
        exercise significant influence over AU Optronics Corp. and MediaTek
        Incorporation's operations, personnel and financial policies.
        Accordingly, the Group changed its method of accounting for its
        investments in AU Optronics Corp. and MediaTek Incorporation from the
        equity method to lower of aggregate cost or market value method.

Note E: Starting from January 2003, the Group was able to exercise significant
        influence over Silicon Integrated Systems Corp. and therefore the method
        of accounting has been changed from lower of cost or market value to
        equity method.

Note F: Among the shares held by the Group in AU Optronics Corp.,
        approximately 148,271 thousand shares with the book value of NT$2,096
        million was utilized as reference shares for the Group's zero coupon
        exchangeable bonds issued in May 2002.

    The Company's income tax returns for all fiscal years through 1999 have been
    assessed and approved by the Tax Authority.

    The Company is located in the Hsin-Chu Science-Based Industrial Park (HSIP).
    In order for business operations to be eligible to locate in the HSIP, the
    operations must be high technology related manufacturing activities. Based
    on the HSIP regulations, a preferential income tax rate of 20%, instead of
    25% applicable to other business entities located in Taiwan, is imposed on
    profits generated from HSIP business operations through the year 2000.
    Starting from 2001, the preferential income tax rate of 20% is no longer
    available to HSIP business operations and the standard tax rate of 25% is
    applied.

    Pursuant to the "Statute for the Establishment and Administration of
    Science-Based Industrial Park", the Company was granted several four-year
    income tax exemption periods with respect to income derived from expansion
    of operations located in HSIP. The starting date of the exemption period
    attributable to the expansion in 1999 has not yet been decided by the
    Company. The other exemption periods will expire in December 2007.

    An enterprise earns an investment tax credit for the amount invested in
    production equipment, research and development expenditure, employee
    training expenditure and other related costs. This credit may be applied
    over a period of five years.

    As of June 30, 2003, the Group's unused investment tax credit is as follows:

    Under the rules of the Income Tax Law, operating loss can be carried forward
    for five years. As of June 30, 2003, the unutilized accumulative loss
    brought forward amounted to NT$16,393 million, which will expire in 2006
    through 2008.

    The new Taiwan imputation tax system requires that any undistributed current
    earnings, on tax basis of a company derived on or after January 1, 1998, be
    subject to an additional 10% corporate income tax if the earnings are not
    distributed before a specific time. This 10% additional tax on undistributed
    earnings paid by the company can be used as tax credit by shareholders,
    including foreign shareholders, against the withholding tax on dividends. In
    addition, the domestic shareholders can claim a proportionate share in the
    company's corporate income tax as tax credit against its individual income
    tax liability effective 1998.

    As of June 30, 2003, the balance of imputation credit account ("ICA") was
    NT$93 million. The actual creditable ratio for the appropriation of 2000 and
    2001 retained earnings was 1.04% and 1.79%, respectively, while the expected
    creditable ratio for the appropriation of 2002 retained earnings was 1.08%.

    The ending balance of unappropriated earnings available for 2003
    appropriation amounted to NT$3,672 million, of which NT$64 million was
    earned prior to January 1, 1998.

(3)  The Group has signed several construction contracts for the expansion of
     its factory. As of June 30, 2003, these construction contracts amounted to
     approximately NT$10.2 billion and the unaccrued portion of the contracts
     was approximately NT$1.58 billion.

(4)  On October 27, 1997, Oak Technology Inc. ("Oak") filed a complaint seeking
     a damage of US$750 million in the Northern District of California alleging
     that the Company breached a Settlement Agreement entered on July 31, 1997
     with respect to a settlement of a dispute between the Company and Oak
     concerning certain CD ROM controller products made by the Company and a
     patent owned by Oak. The Company denied Oak's allegations and on December
     24, 1997, filed its answer and affirmative defenses refuting Oak's claims.
     Based on the allegations that it is Oak which has breached the Settlement,
     the Company simultaneously filed a counterclaim against Oak, seeking
     damages and a return of the millions paid to Oak under the Settlement. In
     addition, the Company further seeks a declaration that the Oak patent is
     invalid and/or unenforceable. Though Oak filed a complaint later with the
     International Trade Commission ("ITC") repeating the allegations made in
     the District Court, both the ITC and the Court of Appeals for the Federal
     Circuit issued a ruling affirming that there was no infringement and no
     violation.

     Oak filed enforceable commitments that it would no longer seek recoveries
     in connection with the Oak patent and accordingly, the District Court
     concluded there was no longer dispute between Oak and the Company on the
     patent and the Company's claim for a declaration of invalidity and
     unenforceability will be dismissed. The Company intends to continue to
     defend these matters vigorously. Furthermore, the management does not
     believe the Oak complaints will have any material adverse impact on the
     Company's operations and/or financial performance.

28.  Financial Instruments

     (1)  The Group uses derivative financial instruments to manage its exposure
          to market risks associated with foreign currency exchange rate and
          interest rate fluctuations.

          a.   The Company utilizes interest rate swap agreements to manage its
               interest rate risks on its floating rate domestic bonds. The
               details are summarized as follows:

               There were no interest rate swap agreements outstanding as of
               December 31, 2001 and 2002.

               As of June 30, 2003, the Company had the following interest rate
               swap agreements in effect:



               Notional Amount                   Contract Period               Interest Rate Received          Interest Rate Paid

                                                                                       LIBOR
                NT$7,500 million           May 20, 2003 to May 20, 2010         4.3% minus USD 12-month            1.48%
                                                                                       LIBOR

               was NT$15 million and the fair value based on quotes from
               financial institutions was NT$216 million. No interest was paid
               or received during the six-month period ended June 30, 2003 as
               the interest is settled annually starting from May 20, 2004. Net
               interest receivable accrued as of June 30, 2003 amounted to NT$15
               million.

     b.   UMCJ, a subsidiary of the Company, entered into foreign currency
          forward exchange contract to manage certain risks arising from adverse
          fluctuations in foreign currency exchange rates.
          The major information is as follows:

          Notional amount and contract period:



                                                    As of December 31, 2001

          There was no foreign currency forward exchange contract outstanding as
          of December 31, 2002.



                                                    As of June 30, 2003

                  Purchase USD             US$5 million                July 31, 2003
                    Sell USD               US$4 million                July 31, 2003


     c.   Transaction risk

          (a)  Credit risk

               There is no significant credit risk exposures with respect to the
               above transactions because the counterparties are usually
               reputable financial institutions with good global standing.

          (b)  Market risk

               The Group entered into forward exchange contracts to hedge the
               effect of exchange rate fluctuations on its receivables and
               payables and entered into interest rate swaps to manage the
               interest rate risk on its floating rate domestic bonds by
               converting it to fixed-rate basis. As a result, no significant
               exposure to market risk from exchange rate and interest rate
               fluctuations is anticipated.

          (c)  Liquidity and cashflow risk

               The cash flow requirements on the above derivative financial
               instruments are limited to the net differences between the spot
               rates and contracted forward rates at settlement dates for
               forward exchange contracts and net interest payables, if any,
               arising from the difference in pay and receive rates for interest
               rate swaps. Therefore, no significant liquidity and cash flow
               risk is anticipated as the Group has sufficient working capital
               to meet the cash flow requirements on settlement.

     The carrying amounts of short-term financial instruments and other
     financial assets (credit-linked deposits) approximate fair values due to
     their short maturities. Short-term financial instruments include cash and
     cash equivalents, notes receivable, accounts receivable, short-term loans,
     notes payable, accounts payable, income tax payable and accrued expenses.

     The fair value of marketable securities, long-term investments and bonds
     payable is based on the quoted market value. If the market values of
     marketable securities and long-term investments are unavailable, net assets
     of the investees are used as fair value.

     The carrying value of long-term loans approximates the fair value as the
     loans bear floating rates.

     b.  Credit Risk

         The counter parties of the above investments are major international
         financial institutions. The repayment in full of these deposits is
         subject to the non-occurrence of one or more credit events, which
         are referenced to the entities' fulfillment of their own obligations
         as well as repayment of their corporate bonds. Upon the occurrence
         of one or more of such credit events, the Group may receive nil or
         less than full amount of these deposits. The Group has undertaken to
         minimize the credit risk by selecting reference entities with high
         credit ratings.

     c.  Liquidity Risk

         Though early withdrawal is not allowed for the above credit-linked
         deposits unless called by the issuer, the anticipated liquidity risk
         is low as most of the contracts are mature within one year.

     d.  Market Risk

         There is no market risk for the above investments except for the
         fluctuations in the exchange rates of US dollars and Japanese Yen to
         NT dollars.

30.  US GAAP Reconciliation

     The accompanying consolidated financial statements have been prepared in
     conformity with generally accepted accounting principles in the Republic of
     China ("ROC GAAP"), which differ in certain material respects from
     generally accepted accounting principles in the United States ("US GAAP").

     Remuneration to Directors and Supervisors - The Company's Articles of
     Incorporation requires a cash remuneration payment to its directors and
     supervisors. Under ROC GAAP, such payments are charged directly to retained
     earnings in the period shareholders approve such payment.

     Under US GAAP, such cash payments should be recorded as compensation
     expense in the period when services are rendered. The difference between US
     GAAP and ROC GAAP in this area would result in adjustments to net income
     and stockholders' equity as shown in the above schedules.

     Employee Bonuses - Certain employees of the Company are entitled to bonuses
     in accordance with provisions of the Company's Articles of Incorporation.
     Employee bonuses are determined as discussed in Note 18. Under ROC GAAP,
     such bonuses are appropriated from retained earnings in the period
     shareholders' approval is obtained, the amount charged against retained
     earnings is based on the par value of the common shares issued.

     Under US GAAP, employee bonus expense is initially accrued when services
     are rendered and both the number of shares to be issued and the price per
     share are known. When bonuses are approved by the shareholders in the
     subsequent year, an additional compensation expense is recorded for the
     difference between the amount initially recorded and the fair market value
     of shares granted to employees. The difference between US GAAP and ROC GAAP
     in this area would result in adjustments to net income and shareholders'
     equity as shown in the above schedules. In addition, there is also a
     reclassification from retained earnings to capital reserve of NT$24,128
     million, NT$27,367 million, NT$29,305 million, NT$29,305 million and
     NT$34,186 million at December 31, 2000, 2001 and 2002, and June 30, 2002
     and 2003.

 (2) Equity Investments - Net income variance between US GAAP and ROC GAAP

     The Group's proportionate share of the income (loss) from an equity
     investee may differ if the equity investee's net income (loss) under ROC
     GAAP differs from US GAAP. The differences between ROC GAAP and US GAAP for
     the equity investees include accounting for compensation, technological
     know-how and investment in marketable securities, etc.

  (3)Marketable Securities and Long-term Investments

     Under ROC GAAP, marketable securities are carried at the lower of aggregate
     cost or market value. Under US GAAP Statement of Financial Accounting
     Standards, ("SFAS") 115, "Accounting for Certain Investments in Debt and
     Equity Securities," debt and equity securities that have readily
     determinable fair values are to be classified as either trading,
     available-for-sale or held-to-maturity securities. Debt securities that the
     Group has the positive intent and ability to hold to maturity are
     classified as held-to-maturity securities and reported at amortized cost.
     Debt and equity securities that are bought and traded for short-term profit
     are classified as trading securities and reported at fair value, with
     unrealized gains and losses included in earnings. Debt and equity
     securities not classified as either held-to-maturity or trading securities
     are classified as available-for-sale securities and reported at fair value,
     with unrealized gains and losses excluded from earnings and reported in a
     separate component of stockholders' equity.

     The Group holds marketable securities that are mainly classified as trading
     securities. The portion of trading gains and losses for the years ended
     December 31, 2000, 2001 and 2002, and for the six-month periods ended June
     30, 2002 and 2003 on trading securities still held at each of the
     respective balance sheet dates were NT$0, NT$19,868, NT$1,771,439,
     NT$(1,325,424) and NT$180,688 respectively.

     The Group holds long-term investments in equity securities where the Group
     does not have the ability to exercise significant influence that are
     classified as available-for-sale securities. Information on sales of
     available-for-sale equity securities for the years ended December 31, 2000,
     2001 and 2002, and for the six-month periods ended June 30, 2002 and 2003

        The Group did not transfer any available-for-sale securities to trading
        securities for the years ended December 31, 2000, 2001 and 2002, and for
        the six-month periods ended June 30, 2002 and 2003. The amount of gains
        (losses) reclassified from accumulated other comprehensive income into
        earnings on available-for-sale securities were NT$46,229, NT$169,049,
        NT$5,034,105, NT$4,574,600 and NT$105,576 for the years ended December
        31, 2000, 2001 and 2002, and for the six-month periods ended June 30,
        2002 and 2003, respectively.

        Under ROC GAAP, if an investor company invests in equity securities that
        are traded in an open market and uses the cost method for valuation
        purposes, then an investor company shall recognize losses if evidence
        suggests that the value of an investment has been impaired and it is
        unlikely that the stock price will recover. The new cost of the
        long-term investment is the book value after recognizing the losses.
        Under US GAAP, for individual securities classified as either
        available-for-sale or held-to-maturity, an enterprise shall determine
        whether a decline in fair value below the amortized cost basis is other
        than temporary. If the decline in fair value is judged to be other than
        temporary, the cost basis of the individual security shall be written
        down to fair value as a new cost basis and the amount of the write-down
        shall be included in earnings. The new cost basis shall not be changed
        for subsequent recoveries in fair value. Subsequent increases in the
        fair value of available-for-sale securities shall be included in the
        other comprehensive income.

        The Group has written down NT$415 million, NT$536 million, NT$1,409
        million, NT$1,314 million and NT$304 million under ROC GAAP against
        certain available-for-sale securities for the years ended December 31,
        2000, 2001 and 2002, and for the six-month periods ended June 30, 2002
        and 2003. For US GAAP purpose, the Group further wrote down an
        additional NT$296 million, NT$3,305 million, NT$781 million, NT$385
        million and NT$522 million for the years ended December 31, 2000, 2001
        and 2002, and for the six-month periods ended June 30, 2002 and 2003.
        Among the NT$1,409 million recognized under ROC GAAP for the year ended
        December 31, 2002, NT$432 million had already been written down under US
        GAAP for the year ended December 31, 2001, which therefore has led to an
        increase in net income under US GAAP for the year ended December 31,
        2002.

              UNITED MICROELECTRONICS CORPORATION AND SUBSIDIARIES
             NOTES TO CONSOLIDATED FINANCIAL STATEMENTS-(Continued)

        Under ROC GAAP, equity investments where a company has an ownership
        interest of at least 20% are generally required to be accounted for
        under the equity method. However, when there is evidence indicating that
        the investor company does not have significant influence over the equity
        investee, despite an ownership interest of 20% or more, the investor
        company should not account for the equity investee under equity method.
        On the contrary, when there is evidence indicating that the investor
        company has significant influence over the equity investee's operating
        and financial policies, despite an ownership interest of less than 20%,
        the investor company will account for the equity investee under equity
        method. Under US GAAP, the Group is required to use the equity method of
        accounting for an investment in common stock when the investment in
        voting stock gives it the ability to exercise significant influence over
        operating and financial policies of an investee. An investment (direct
        or indirect) of 20% or more of the voting stock of an investee leads to
        a presumption that in the absence of evidence to the contrary an
        investor has the ability to exercise significant influence over an
        investee. There were no significant differences between ROC GAAP and US
        GAAP on balance sheets as of December 31, 2001 and 2002, and on
        statements of operations for the three years ended December 31, 2000,
        2001 and 2002, and for the six-month period ended June 30, 2002. Under
        ROC GAAP, when an investor company's ownership percentage of an
        investee's outstanding common stock is the highest among shareholders,
        the investor company is considered to have significant influence over
        the investee and equity accounting shall be applied, despite an
        ownership interest of less than 20%. However, under US GAAP, this does
        not qualify for a relationship of significant influence and hence equity
        accounting shall not be applied unless the investor holds more than 20%
        of the voting rights. The difference between US GAAP and ROC GAAP in
        this area would result in a decrease in equity in loss of investees of
        NT$255 million and an increase in unrealized loss on available-for-sale
        securities of NT$664 million, respectively, for the six-month period
        ended June 30, 2003.

    (4) Treasury Stock and Gain on Disposal of Treasury Stock

        Under ROC GAAP, when the Group's equity investee sells the Company's
        stock it recognizes the gain or loss in its statement of operations.
        Under US GAAP, the Group's equity in income (loss) of an investee is
        adjusted to eliminate the Company's proportionate share of any such
        gains or losses. Further, the Company's stock owned by an investee is
        proportionately deducted from the investment as treasury stock.

    (5) Technological Know-how

        The Group entered into three joint ventures from 1995 through 1996. Both
        the Group and the joint venture partner contributed cash to the joint
        ventures. In addition, the Group contributed technological know-how to
        the joint ventures for shares of the joint venture companies. Both
        parties mutually agreed to the value of this transferred technological
        know-how before the transfer of shares. The technological know-how
        contributed has not been recognized on the Group's balance sheet, as
        these were internally generated intangible assets with no carrying
        value.

                                      F-65



              UNITED MICROELECTRONICS CORPORATION AND SUBSIDIARIES
             NOTES TO CONSOLIDATED FINANCIAL STATEMENTS-(Continued)

        Under ROC GAAP, the Group recognized the cash contributed as the initial
        cost of the investment. The difference between the proportionate share
        of the net assets in the joint venture and the cash contributed is
        amortized to income over the estimated useful life of the technological
        know-how, which is the source of this difference. Further, under ROC
        GAAP, the joint venture recognized a value for the technological
        know-how as an intangible asset contributed, which is the cause of the
        difference between the proportionate share of the net assets and the
        cash contributed.

        Under US GAAP, the investor initially records its joint venture
        investment at cost, representing the amount of cash contributed and/or
        net book value of non-cash assets contributed. The joint venture
        normally records cash investments at the amount contributed, the
        non-cash assets at fair value and intangible assets at the predecessor
        basis, which is normally zero. The difference between the proportionate
        share of the net assets in the joint venture and the cost of the
        investments is amortized to income over a period of five years. The
        joint venture does not recognize value for the technological know-how
        contributed, thus causing a difference with ROC GAAP.

        This practice only applies to entities that are being consolidated or
        accounted for under the equity method.

    (6) Convertible and Exchangeable Bonds

        Convertible Bonds

        When convertible securities are issued, ROC GAAP does not recognize or
        account for any beneficial conversion feature embedded in the
        securities. Under US GAAP, as prescribed in the Emerging Issues Task
        Force ("EITF") Topic D-60, as amended by EITF 98-5, Accounting for the
        Issuance of Convertible Preferred Stock and Debt Securities with a
        Non-detachable Conversion Feature, such beneficial conversion features
        should be recognized and measured by allocating a portion of the
        proceeds equal to the intrinsic value of that feature to capital
        reserve. That amount should be calculated at the issuance date as the
        difference between the conversion price and the fair value of the common
        stock, multiplied by the number of shares into which the security is
        convertible (intrinsic value). As a result, a bond discount is
        recognized by allocating a portion of the proceeds equal to the
        intrinsic value of that feature to capital reserve. The Group recognized
        interest expense of NT$1,274 million from February 1994, the date of
        issuance of the bonds, to May 1994, the date of first conversion,
        relating to a NT$1.5 billion bond. The Group also recognized interest
        expense of NT$6,086 million from June 1994, the date of issuance of the
        bonds, to May 1996, the date of first conversion, relating to an US$160
        million bond.

                                      F-66



              UNITED MICROELECTRONICS CORPORATION AND SUBSIDIARIES
             NOTES TO CONSOLIDATED FINANCIAL STATEMENTS-(Continued)

        The Group recognized interest expense of approximately NT$800 million
        from May 10, 2000, the date of issuance of the bonds, to June 1, 2000,
        the date of first conversion, related to its (Yen)10 billion bond.

        In addition, according to EITF 85-17, the Group recognized an imputed
        interest expense together with a compensation interest of NT$570 million
        in total for the year ended December 31, 2002, and NT$293 million and
        NT$70 million for the six-month periods ended June 30, 2002 and 2003,
        respectively, relating to the US$302.4 million zero coupon convertible
        bonds issued on December 12, 2001. Upon reacquisition of the convertible
        bonds, the relevant interest expenses accrued in prior periods will be
        released to gain/loss on requisition of bonds accordingly.

        When a subsidiary or investee (the "Issuer") issues convertible bonds to
        other parties, including the parent or investor, and bonds are converted
        into shares of the Issuer, the parent's or investor's ownership in the
        Issuer may decrease. Also, the parent's or investor's ownership in the
        Issuer may increase upon conversion. Under ROC GAAP, this decrease or
        increase is treated as a one-time decrease or increase to capital
        reserve and /or retained earnings.

        Under US GAAP, a decrease in ownership is recognized as a gain or loss
        in the statement of operations upon conversion, as long as the value of
        the proceeds can be objectively determined and the realization of the
        gain is reasonably assured at the time of conversion. Under US GAAP, for
        the years ended December 31, 2000, 2001 and 2002, and for the six-month
        periods ended June 30, 2002 and 2003, approximately NT$141 million, nil,
        NT$9.5 million, NT$9.8 million and nil were reclassified from capital
        reserve to a gain in the income statement relating to these
        transactions.

        Further under US GAAP, an increase in ownership is treated as a purchase
        of additional shares and the difference between the total cost of the
        investment and the proportionate share of the fair value net assets is
        first allocated to identifiable tangible and intangible assets and the
        remaining unallocated amounts to goodwill, which was amortized over
        their respective estimated useful lives up to January 1, 2002. Upon the
        first adoption of the SFAS No.141, "Business Combination" and SFAS
        No.142, "Goodwill and Other Intangible Assets" by the Group on January
        1, 2002, goodwill created from acquisition is no longer to be amortized.
        Under US GAAP, for the year ended December 31, 2000, the Group
        capitalized goodwill of NT$468.3 million related to a subsidiary's
        convertible bond, with NT$49.4 million and NT$93.7 million being
        amortized in the statement of operations for the years ended December
        31, 2000 and 2001, respectively, and nil for the subsequent periods.
        Further, upon conversion of an equity investment's bond, which increased
        the Group's ownership, the difference of NT$519 million between the
        total cost of the investment and proportionate share of the fair value
        net assets was being amortized over 5 years, which accounted for NT$54.8
        million and NT$103.9 million for the years ended December 31, 2000 and
        2001, respectively. Again, due to the first adoption of SFAS No.141 &
        142 on January 1, 2002, no amortization was made since then. Details of
        the accounting treatment on goodwill are set out in the footnote
        "Adoption of SFAS No.141 & 142".

             NOTES TO CONSOLIDATED FINANCIAL STATEMENTS-(Continued)

     The Group has invested in convertible bonds. Under the SFAS No. 133,
     "Accounting for Derivative Instruments and Hedging Activities", an embedded
     derivative instrument shall be separated from the host contract and
     accounted for as a derivative instrument pursuant to the statement if a)
     the economic characteristics and risks of the embedded derivative
     instrument are not clearly and closely related to the economic
     characteristics and risks of the host contract, b) the contract that
     embodies both the embedded derivative instrument and the host contract is
     not remeasured at fair value with changes in fair value reported in
     earnings as they occur and c) a separate instrument with the same terms as
     the embedded derivative instrument would be a derivative instrument subject
     to the requirements of SFAS No. 133. For an available-for-sale convertible
     debt securities, the conversion option embedded must be separated from the
     debt host contract and accounted for as a derivative instrument provided
     that the conversion option would, as a freestanding instrument, be a
     derivative instrument subject to the requirement of SFAS No. 133 since the
     embedded conversion option satisfied the above three criteria. As a result,
     the embedded option contracts in the convertible bonds with the initial
     amount of NT$104 million, NT$57 million and NT$64 million in total,
     respectively, at date of purchase were separated from the debt host
     contracts and were accounted for as trading securities reporting at fair
     value, with an unrealized gain(loss) of NT$(25) million, NT$14 million and
     NT$122 million included in earnings for the year ended December 31, 2002
     and for the six-month periods ended June 30, 2002 and 2003. On the other
     hand, the debt host contracts with the initial amount of NT$ 2,397 million,
     NT$1,995 million and NT$755 million were classified as available-for-sale
     securities, with an unrealized gain(loss) of NT$46 million, NT$(76) million
     and NT$(83) million reported in other comprehensive income for the year
     ended December 31, 2002 and for the six-month periods ended June 30, 2002
     and 2003, respectively.

     Exchangeable Bonds
     Bonds that are exchangeable into common stock of a third party is an
     expansion on the concept of convertible bonds.

     Under ROC GAAP, when exchangeable bondholders exercise their rights to
     exchange for the reference shares, the book value of bonds is to be offset
     with the book value of the investment in the reference shares together with
     the related stockholder's equities, with the difference recognized as gain
     or loss on disposal of investments.

                                      F-68



              UNITED MICROELECTRONICS CORPORATION AND SUBSIDIARIES
             NOTES TO CONSOLIDATED FINANCIAL STATEMENTS-(Continued)

     Under US GAAP, as prescribed by SFAS No.133 and discussed above, the
     exchangeable feature within exchangeable bonds is an embedded equity
     derivative within a debt instrument that satisfies the three criteria which
     requires it to be bifurcated and separately accounted for. The fair value
     of the exchangeable option feature of the Group's first exchangeable bonds
     issued in May 2002 was measured as NT$2,025 million as at the date of
     issuance, which resulted to a reclassification from the bond value to
     financial instrument liability under US GAAP accordingly. As of December
     31, 2002 and June 30, 2003, the fair value of the option was NT$273 million
     and NT$257 million, respectively, resulting in a gain of NT$1,752 million
     and NT$16 million being recognized for the year ended December 31, 2002 and
     for the six-month period ended June 30, 2003 under US GAAP, respectively.

 (7) Principle of Acquisition under the Purchase Method

     Under ROC GAAP, the fair value of the net assets received is deemed to be
     the value of the consideration for the acquisition of the remaining
     interests in United Semiconductor, United Silicon, UTEK Semiconductor and
     United Integrated Circuits and is reflected in the common stock and capital
     reserve in the balance sheet. The Group estimated the fair value of the net
     assets acquired through two valuation models, profitability and net worth
     model, and a discounted cash flows model. They also used other
     considerations such as the valuation of current operations, synergies,
     technical knowledge and future prospects. Under US GAAP, the acquisition
     was accounted for using the purchase method of accounting and the purchase
     price was determined using the market value of the shares exchanged. The
     difference between the fair value of the shares exchanged and the fair
     value of the net assets acquired creates goodwill. Goodwill was amortized
     on a straight-line basis over ten years. Upon the adoption of SFAS No.141 &
     142 on January 1, 2002 by the Group, the goodwill ceased to be amortized
     and is subject to impairment test only. Please refer to "Adoption of SFAS
     No. 141 and 142" for details. The purchase price under US GAAP was
     determined based on the average closing market price of the Company's stock
     on the five trading days beginning two days before June 16, 1999, the first
     day of trading after the announcement of the acquisition to determine the
     fair values of the shares exchanged.

     The purchase price was allocated to the tangible and intangible assets and
     liabilities acquired based on their estimated fair values at January 3,
     2000, as follows (in NT$ millions):

            Current assets                                   $ 38,188
            Other assets                                       47,673
            Liabilities                                       (43,318)
            Goodwill                                          122,835
                                                    -----------------
            Purchase price                                   $165,378
                                                    =================

     As of January 1, 2002, the carrying value of the unamortized balance of the
     goodwill was measured as NT$98,268 million.

 (8) Earnings Per Share

     Under ROC GAAP, basic earnings per share are calculated by dividing net
     income by the weighted average number of shares outstanding during the
     year. Diluted earnings per share are calculated by taking basic earnings
     per share into consideration plus additional common shares that would have
     been outstanding if the dilutive share equivalents had been issued. The net
     income would also be adjusted for the interest derived from any underlying
     dilutive share equivalents. The weighted-average outstanding shares are
     restated for stock dividends issued and shares issued for employee bonuses,
     as described under (1) Compensation above.

     Under US GAAP, basic earnings per share are calculated by dividing net
     income by the weighted average number of shares outstanding during the
     year. Shares issued for employee bonus will affect the current year's
     earnings per share only. Diluted earnings per share are calculated by
     taking into consideration additional common shares that would have been
     outstanding if the dilutive share equivalents had been issued. The net
     income would also be adjusted for the interest derived from any underlying
     dilutive share equivalents.

 (9) Tax Effect of US GAAP Adjustments

     Undistributed earnings generated after 1997 are subject to a 10% tax in
     compliance with the Income Tax Law of the ROC. Under ROC GAAP, the 10% tax
     on undistributed earnings is recorded as an expense at the time
     shareholders resolve that its earnings shall be retained. Under US GAAP,
     the Group would measure its income tax expense, including the tax effects
     of temporary differences, using the tax rate that includes the tax on
     undistributed earnings.

(10) Principles of Consolidation

     Under ROC GAAP, certain 50% or more owned subsidiaries are not consolidated
     if they meet specific exclusion rules detailed in the accounting policies
     footnote. Under US GAAP, consolidation is generally required when one of
     the companies in a group directly or indirectly has a controlling financial
     interest in the other companies. The usual condition for controlling
     financial interest is ownership of a majority of the voting interest and,
     therefore, as a general rule ownership by one company, directly or
     indirectly, of over fifty percent of the outstanding voting shares of
     another company is a condition pointing towards consolidation.
     Consolidation of majority-owned subsidiaries is required in the preparation
     of consolidated financial statements, unless (i) control is considered
     temporary or (ii) control does not rest with the majority owner. As such,
     Under US GAAP, the Company consolidates those subsidiaries that are
     excluded from consolidation under ROC GAAP due to the exclusion rules
     (Fortune Venture Capital Corporation, UMC Capital Corporation, United
     Microelectronics Corp. (Samoa), United Foundry Services Inc., and Sigence
     Inc.) The net income and stockholders' equity variances between US GAAP and
     ROC GAAP for those entities are included in the adjustment for equity
     investments.

(11) Stock Dividends

     Under ROC GAAP, stock dividends are recorded at par with a charge to
     retained earnings. Under US GAAP, if the ratio of distribution is less than
     25 percent of the same class of shares outstanding, the fair value of the
     shares issued should be charged to retained earnings. The accumulative
     effect of these dividends would have decreased retained earnings and
     increased capital reserve for the years ended December 31, 2000, 2001 and
     2002, and for the six-month periods ended June 30, 2002 and 2003, by
     approximately NT$127,880 million, NT$187,416 million, NT$243,546 million,
     NT$187,416 million, and NT$243,546 million, respectively.

(12) Other financial assets

     Interest rate swap
     To eliminate the variability of cash flows in the interest payments of its
     NT$15 billion variable-rate domestic bonds issued in May to June 2003, the
     Company entered into interest rate swap agreements with notional amount of
     NT$15 billion that effectively convert the floating-rate domestic bonds to
     fixed-rate basis over the term of the bonds. Under ROC GAAP, the periodic
     cash settlement under the interest rate swap is accrued in the statement of
     operations as an adjustment to interest expense. The net receivable/payable
     under the interest rate swap is included as "other financial assets".
     Changes in fair value of the interest rate swap, as hedging instrument, are
     not required to be accounted for as of the balance sheet date.

     Under US GAAP, the SFAS No. 133 requires companies to recognize all of its
     derivative instruments as either assets or liabilities in the statement of
     financial position at fair value. The accounting for changes in the fair
     value of a derivative instrument depends on whether it has been designated
     and qualifies as part of a hedging relationship and further, on the type of
     hedging relationship. For those derivative instruments that are designated
     and qualify as hedging instruments, a company must designate the hedging
     instrument, based upon the exposure being hedged, as a fair value hedge,
     cash flow hedge or a hedge of a net investment in a foreign operation.

     The Company's interest rate swap agreements were designated as cash flow
     hedges. For derivative instruments that are designated and qualify as a
     cash flow hedge to hedge the exposure to variability in expected future
     cash flows that is attributable to a particular risk, the effective portion
     of the gain or loss on the derivative instrument is reported as other
     comprehensive income, a component of stockholders' equity, and reclassified
     into earnings in the same period or periods during which the hedged
     transaction affects earnings. Therefore, to recognize the change in fair
     value of the interest rate swaps, an amount of NT$216 million was included
     in other comprehensive income under US GAAP for the six-month period ended
     June 30, 2003.

           Credit-linked deposits and repackage bonds

           The Group held several credit-linked deposits and repackage bonds
           classified as other financial assets under ROC GAAP as of June 30,
           2003. As no early withdrawal is allowed under the deposit/repackage
           agreements, such financial instruments are included in
           held-to-maturity securities under US GAAP.

           The repayment in full, including any accrued interest, of these
           deposits is subject to the non-occurrence of one or more credit
           events, which are referenced to the entities' fulfillment of their
           own obligations as well as repayment of their loan or corporate
           bonds. Upon the occurrence of one or more of such
           credit events, the Group may receive nil or less than the full amount
           of these deposits and any payment received may be delayed due to the
           occurrence of certain events.

           Since the credit-linked options were, a) the economic characteristics
           and risks of the embedded derivative instrument are not clearly and
           closely related to the economic characteristics and risks of the
           deposit, b) the contract that embodies both the embedded derivative
           instrument and the host contract is not remeasured at fair value with
           changes in fair value reported in earnings as they occur and c) a
           separate instrument with the same terms as the embedded derivative
           instrument would be a derivative instrument subject to the
           requirements of SFAS No. 133, these credit-linked options were
           bifurcated from such deposits with the amount of NT$29 million as of

     (13)  Gross Profit and Operating Income

           Inventory loss provision, gain from disposal of property, plant and
           equipment, and gain from foreign currency exchange were presented
           below the operating income subtotal in the statement of operations as
           permitted under ROC GAAP. Under US GAAP, the inventory loss provision
           is included in the determination of gross profit. Further, the
           inventory loss provision, gain from disposal of property, plant and
           equipment, and gain from foreign currency exchange are included in
           the determination of operating income.

     (14)  Gain on Disposal of Fixed Assets

           Under ROC GAAP, gains and losses from the disposal of fixed assets
           are both recognized in the statement of operations, with gains
           reclassified from retained earnings to capital reserve. However,
           according to amendments in ROC Company Law, such transfer of gains to
           capital reserve shall no longer be required with effect on January 1,
           2001. The accumulated gain transferred in prior years can be
           transferred back from the capital reserve and be treated as a
           one-time increase in retained earnings subject to shareholder's
           approval. Under US GAAP, the reclassification of the gain from
           retained earnings is not permitted. As of June 30, 2003, the
           accumulated gain transferred in prior years by investees that has not
           been transferred back from capital reserve under ROC GAAP amounted to
           NT$1.7 million, which had been transferred under US GAAP.

     (15)  Reclassification of Certificates of Deposit

           Under ROC GAAP, cash and cash equivalents include certificates of
           deposit. Under US GAAP, cash equivalents are short-term, highly
           liquid investments that are readily convertible to cash with original
           maturities of three months or less. Thus, certificates of deposit
           with original maturities of greater than three months are classified
           as cash equivalents under ROC GAAP but should be included in
           marketable securities for trading purpose under US GAAP.

     (16)  Employee Stock Options

           The Group has elected to follow Accounting Principles Board Opinion
           No. 25, "Accounting for Stock Issued to Employees" (APB 25) and
           related interpretations in accounting for its employee stock options
           because, as discussed below, the alternative fair value accounting
           provided for under SFAS No. 123, "Accounting for Stock-Based
           Compensation", requires use of option valuation models that were not
           developed for use in valuing employee stock options. Under APB 25,
           because the exercise price of the Company's employee stock options
           equals the market price of the underlying stock on the date of grant,
           no compensation expense is recognized for the Company.

             NOTES TO CONSOLIDATED FINANCIAL STATEMENTS-(Continued)

           On September 11, 2002, the Company was authorized to issue Employee
           Stock Options. The total number of options to be granted under the
           plan is one billion units, with each unit entitling the optionee to
           subscribe for one share of the Company's common stock. The grant
           period for options is six years and an optionee may exercise his/her
           options starting from two years after the grant: employees may
           exercise up to 50% of the options after two years, up to 75% after
           three years and up to 100% after four years. The total number of
           option units outstanding as of June 30, 2003 was 951,456 thousand
           units.

           Pro forma information regarding net income and earnings per share is
           required by SFAS No. 123, and has been determined as if the Group had
           accounted for its employee stock options under the fair value method
           of that Statement. The fair value for these options was estimated at
           the date of grant using a Black-Scholes option pricing model with the
           following weighted-average assumptions for the year ended December
           31, 2002 and for the six-month period ended June 30, 2003,
           respectively: risk-free interest rate of 1.98% and 1.96%; dividend
           yields of 22.63%; volatility factors of the expected market price of
           the Company's common stock of 0.54 and 0.53; and a weighted-average
           expected life of the option of 4.4 years.

           The Black-Scholes option valuation model was developed for use in
           estimating the fair value of traded options which have no vesting
           restrictions and are fully transferable. In addition, option
           valuation models require the input of highly subjective assumptions
           including the expected stock price volatility. Because the Group's
           employee stock options have characteristics significantly different
           from those of traded options, and because changes in the subjective
           input assumptions can materially affect the fair value estimate, in
           management's opinion, the existing models do not necessarily provide
           a reliable single measure of the fair value of its employee stock
           options.

             NOTES TO CONSOLIDATED FINANCIAL STATEMENTS-(Continued)

Concentration of credit risk

The Group designs, develops, manufactures and markets a variety of semiconductor
products. Financial instruments that potentially subject the Group to
significant concentrations of credit risk consist principally of cash and cash
equivalents and trade accounts and notes receivable. The Group limits its
exposure to credit loss by depositing its cash and cash equivalents with high
credit quality financial institutions. The Group's revenues and trade accounts
and notes receivable are derived primarily from the sale of production foundry
wafers, including memory and logic products and wafers. For the year ended
December 31, 2002 and for the six-month period ended June 30, 2003, the Group
distributes its products on a global basis but mainly to customers in North
America (37.64% and 38.08%, respectively), Asia (51.25% and 48.31%,
respectively), and Europe and others (11.11% and 13.61%, respectively). The
Group's sales are primarily denominated in currencies other than NT Dollars,
primarily US Dollars. Two customers' revenue represented 12% and 13%,
respectively, of the consolidated revenue for the year ended December 31, 2002
and one customer's revenue represented 10% of the consolidated revenue for the
six-month period ended June 30, 2003. The Group routinely assesses the financial
strength of substantially all customers. The Group also requires collateral for
certain sales to mitigate the credit risk.

Adoption of SFAS No.141 and 142

In June 2001, the Financial Accounting Standard Board (FASB) issued Statement of
Financial Accounting Standards (SFAS) No. 141, "Business Combinations", and SFAS
No. 142, "Goodwill and Other Intangible Assets". SFAS No. 141 requires that the
purchase method of accounting be used for all business combinations initiated
after June 30, 2001 as well as all purchase method business combinations
completed after June 30, 2001. SFAS No. 141 also specifies criteria intangible
assets acquired in a purchase method business combination must meet to be
recognized and reported apart from goodwill, noting that any purchase price
allocable to an assembled workforce may not be accounted for separately. SFAS
No. 142 requires that goodwill and intangible assets with indefinite useful
lives should no longer be amortized, but instead be tested for impairment at
least annually in accordance with the provisions of SFAS No. 142. SFAS No. 142
also requires that intangible assets with estimable useful lives be amortized
over their respective estimated useful lives to their estimated residual values,
and reviewed for impairment in accordance with SFAS No. 144, "Accounting for the
Impairment or Disposal of Long-lived Assets".

an equity investee were no longer to be amortized but instead subject to
impairment test annually or when indication of impairment is noted. Similarly,
the goodwill created upon conversion of convertible bonds ceased to be
amortized. The annual goodwill impairment test performed by the Group did not
result in the recognition of any impairment loss as of December 31, 2002 and no
indication of impairment is noted during the six-month period ended June 30,
2003.

As of January 1, 2002, the unamortized goodwill amounted to NT$98,593 million,
and unamortized equity-method goodwill (included in long-term investment)
amounted to NT$526 million. The information on net income exclusive of
amortization expense related to the abovementioned goodwill is presented as
follows:

             NOTES TO CONSOLIDATED FINANCIAL STATEMENTS-(Continued)

On May 15, 2002, the Company acquired 100% of the interest in UMC BV with a cash
consideration of approximately NT$187 million. UMC BV is principally engaged in
the business of sales of semiconductor products and providing related foundry
services. The Company expected to develop UMC BV into its major communication
channel on sales to Europe.

The estimated fair value of the assets acquired and liabilities assumed at the
date of acquisition are summarized as follows:

Adoption of SFAS No. 143, 146 and FIN 45

In June 2001, the FASB issued SFAS No. 143, "Accounting for Asset Retirement
Obligations", which addresses financial accounting and reporting for obligations
associated with the retirement of tangible long-lived assets and the associated
asset retirement costs. The standard applies to legal obligations associated
with the retirement of long-lived assets that result from the acquisition,
construction, development and (or) normal use of the asset.

SFAS No. 143 requires that the fair value of a liability for an asset retirement
obligation be recognized in the period in which it is incurred if a reasonable
estimate of fair value can be made. The fair value of the liability is added to
the carrying amount of the associated asset and this additional carrying amount
is depreciated over the life of the asset. The liability is accreted at the end
of each period through charges to operating expense. If the obligation is
settled for other than the carrying amount of the liability, the Group will
recognize a gain or loss on settlement.

              UNITED MICROELECTRONICS CORPORATION AND SUBSIDIARIES
             NOTES TO CONSOLIDATED FINANCIAL STATEMENTS-(Continued)

In June 2002, the FASB issued SFAS No.146 "Accounting for Costs Associated with
Exit or Disposal Activities." The Statement represents the second and final
phase of the FASB's project on accounting for the impairment or disposal of long
lived assets and for obligations associated with exit or disposal activities.
The adoption of SFAS No. 143 and SFAS No. 146 in January 2003 did not have any
material effect on the Group's financial position, results of operations, and
cash flows.

In November 2002, the FASB issued Interpretation No.45, "Guarantor's Accounting
and Disclosure Requirements for Guarantees, Including Indirect Guarantees of
Indebtedness of Others" ("FIN 45"). FIN 45 requires certain guarantees to be
recorded at fair value, which is different from the general current practice of
recording a liability only when a loss is probable and reasonably estimable, as
those terms are defined in SFAS No.5, "Accounting for Contingencies." FIN 45
also requires a guarantor to make significant new disclosures for virtually all
guarantees even if the likelihood of the guarantor's having to make payments
under the guarantee is remote. The disclosure requirements of FIN 45 are
effective for financial statements of interim or annual periods ending after
December 15, 2002 and the initial recognition and initial measurement provisions
of FIN 45 are applicable on a prospective basis to guarantees issued or modified
after December 31, 2002, irrespective of the guarantor's fiscal year-end. As of
June 30, 2003, except for guarantee options in credit-linked deposits, which the
Group has bifurcated and fair valued, there is no other guarantees issued or
modified by the Group after December 31, 2002.

New Accounting Pronouncements

In January 2003, the FASB issued Interpretation No. 46, "Consolidation of
Variable Interest Entities" ("FIN46"). FIN 46 requires an investor with a
majority of the variable interests in a variable interest entity ("VIE") to
consolidate the entity and also requires majority and significant variable
interest investors to provide certain disclosures. A VIE is an entity in which
the equity investors do not have a controlling interest or the equity investment
at risk is insufficient to finance the entity's activities without receiving
additional subordinated financial support from the other parties. FIN 46's
consolidation provisions apply immediately to variable interests in VIEs created
after January 31, 2003 and did not have any material impact on the Group's
consolidated financial statements for the six-month period ended June 30, 2003.
FIN 46 shall also apply in the first fiscal year or interim period beginning
after June 15, 2003 to VIEs in which a public company holds a variable interest
that is acquired before February 1, 2003. The Group is currently reviewing its
investment portfolio of early stage entities to evaluate the impact of the
adoption of the interpretation.

              UNITED MICROELECTRONICS CORPORATION AND SUBSIDIARIES
             NOTES TO CONSOLIDATED FINANCIAL STATEMENTS-(Continued)

In April 2003, the FASB issued SFAS No. 149, "Amendment of Statement 133 on
Derivative Instruments and Hedging Activities". This Statement amends and
clarifies financial accounting and reporting for derivative instruments,
including certain derivative instruments embedded in other contracts and for
hedging activities under SFAS No. 133. SFAS No. 149 is effective for contracts
entered into or modified after June 30, 2003. For those provisions related to
SFAS No. 133 that have been effective prior to June 15, 2003, they should
continue to be applied in accordance with their respective effective dates.

In May 2003, the FASB issued SFAS Statement No. 150, "Accounting for Certain
Financial Instruments with Characteristics of both Liabilities and Equity". This
Statement establishes standards for how an issuer classifies and measures
certain financial instruments with characteristics of both liabilities and
equity. It requires that an issuer classify a financial instrument that is
within its scope as a liability (or an asset in some circumstances). SFAS No.
150 is effective for financial instruments entered into or modified after May
31, 2003, and otherwise is effective at the beginning of the first interim
period beginning after June 15, 2003. The adoption of SFAS No. 149 and 150 is
not expected to have a material effect on earnings or financial position of the
Group.

In November 2002, the EITF reached a consensus on EITF No. 00-21, "Revenue
Arrangements with Multiple Deliverables". EITF No. 00-21 provides guidance on
when and how to separate elements of an arrangement that may involve the
delivery or performance of multiple products, services, and/or rights to use
assets into separate units of accounting. This consensus, which was modified in
May 2003, is applicable to arrangements entered into for reporting periods
beginning after June 15, 2003. The Group does not expect a material impact on
its financial statements resulting from the adoption of the issue.
