REVIEW REPORT OF INDEPENDENT ACCOUNTANTS

English Translation of a Report Originally Issued in Chinese

To United Microelectronics Corporation

We have reviewed the accompanying balance sheets of United Microelectronics Corporation (the Company) as of March 31, 2008 and 2007, and the related statements of income and cash flows for the three-month periods ended March 31, 2008 and 2007. These financial statements are the responsibility of the Companys management. Our responsibility is to issue the review report based on our reviews. As described in Note 4(8) to the financial statements, certain long-term investments were accounted for under the equity method based on financial statements as of March 31, 2008 and 2007 of the investees, which were reviewed by other auditors. Our review insofar as it relates to the investment (loss) income amounting to NT$(45) million and NT$227 million for the three-month periods ended March 31, 2008 and 2007, respectively, and the related long-term investment balances of NT$4,255 million and NT$5,435 million as of March 31, 2008 and 2007, respectively, is based solely on the reports of the other auditors.

We conducted our reviews in accordance with the Statements of Auditing Standards No. 36, Review of Financial Statements of the Republic of China. A review is limited primarily to applying analytical procedures to financial data and making inquiries of persons responsible for financial and accounting matters. It is substantially less in scope than an audit conducted in accordance with generally accepted auditing standards, the objective of which is the expression of an opinion regarding the financial statement taken as a whole. Accordingly, we do not express such an opinion.

Based on our reviews and the reports of the other auditors, we are not aware of any material modifications or adjustments that should have been made to the financial statements referred to above in order for them to be in conformity with requirements of the Business Entity Accounting Act and Regulation on Business Entity Accounting Handling with respect to financial accounting standard, Guidelines Governing the Preparation of Financial Reports by Securities Issuers, and accounting principles generally accepted in the Republic of China.

As described in Note 3 to the financial statements, effective January 1, 2008, the Company adopted Accounting Research and Development Foundation Interpretation No. 96-052, and recognized share-based employee bonuses and remunerations to directors and supervisors as expenses rather than as a distribution of retained earnings.

NOTES TO UNAUDITED FINANCIAL STATEMENTS

March 31, 2008 and 2007

(Expressed in Thousands of New Taiwan Dollars unless Otherwise Specified)

HISTORY AND ORGANIZATION

United Microelectronics Corporation (the Company) was incorporated in May 1980 and commenced operations in April 1982. The Company is a full service semiconductor wafer foundry, and provides a variety of services to satisfy customer needs. These services include intellectual property, embedded IC design, design verification, mask tooling, wafer fabrication, and testing. The Companys common shares were publicly listed on the Taiwan Stock Exchange (TSE) in July 1985 and its American Depositary Shares (ADSs) were listed on the New York Stock Exchange (NYSE) in September 2000.

The numbers of employees as of March 31, 2008 and 2007 were 13,571 and 13,415, respectively.

SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

The financial statements were prepared in conformity with requirements of the Business Entity Accounting Act and Regulation on Business Entity Accounting Handling with respect to financial accounting standard, Guidelines Governing the Preparation of Financial Reports by Securities Issuers and accounting principles generally accepted in the Republic of China (R.O.C.).

Summary of significant accounting policies is as follows:

Use of Estimates

The preparation of the Companys financial statements in conformity with generally accepted accounting principles requires management to make reasonable estimates and assumptions that will affect the amount of assets and liabilities, the disclosure of contingent assets and liabilities at the date of the financial statements and the reported amount of revenues and expenses during the reported period. The actual results may differ from those estimates.

Foreign Currency Transactions

Transactions denominated in foreign currencies are remeasured into the local functional currencies and recorded based on the exchange rates prevailing at the transaction dates. Monetary assets and liabilities denominated in foreign currencies are remeasured into the local functional currencies at the exchange rates prevailing at the balance sheet date, with the related exchange gains or losses included in the statements of income. Translation gains or losses from investments in foreign entities are recognized as cumulative translation adjustment in stockholders equity.

Non-monetary assets and liabilities denominated in foreign currencies that are reported at fair value with changes in fair value charged to the statements of income, are remeasured at the exchange rate at the balance sheet date, with related exchange gains or losses recorded in the statements of income. Non-monetary assets and liabilities denominated in foreign currencies that are reported at fair value with changes in fair value charged to stockholders equity, are remeasured at the exchange rate at the balance sheet date, with related exchange gains or losses recorded as cumulative translation adjustment in stockholders equity. Non-monetary assets and liabilities denominated in foreign currencies and reported at cost are remeasured at historical exchange rates.

Translation of Foreign Currency Financial Statements

The financial statements of the Companys Singapore branch (the Branch) are translated into New Taiwan Dollars using the spot rates at the balance sheet date for asset and liability accounts and average exchange rates for profit and loss accounts. The cumulative translation effects from the Branch using functional currencies other than New Taiwan Dollars are included in the cumulative translation adjustment in stockholders equity.

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, including commercial paper with original maturities of three months or less.

Financial Assets and Financial Liabilities

In accordance with ROC Statement of Financial Accounting Standard (SFAS) No. 34, Financial Instruments: Recognition and Measurement and the Guidelines Governing the Preparation of Financial Reports by Securities Issuers, financial assets are classified as either financial assets at fair value through profit or loss, held-to-maturity financial assets, financial assets measured at cost, or available-for-sale financial assets. Financial liabilities are recorded at fair value through profit or loss.

The Company accounts for purchase or sale of financial instruments as of the trade date, which is the date the Company commits to purchase or sell the asset or liability. Financial assets and financial liabilities are initially recognized at fair value plus acquisition or issuance costs.

a. Financial assets and financial liabilities at fair value through profit or loss

Financial instruments held for short-term sale or repurchase purposes and derivative financial instruments not qualified for hedge accounting are classified as financial assets or liabilities at fair value through profit or loss.

This category of financial instruments is measured at fair value and changes in fair value are recognized in the statements of income. Stock of listed companies, convertible bonds, and closed-end funds are measured at closing prices as of the balance sheet date. Open-end funds are measured at the unit price of the net assets as of the balance sheet date. The fair value of derivative financial instruments is determined by using valuation techniques commonly used by market participants in the industry.

b. Held-to-maturity financial assets

Non-derivative financial assets with fixed or determinable payments and fixed maturity are classified as held-to-maturity financial assets if the Company has both the positive intention and ability to hold the financial assets to maturity. Investments intended to be held to maturity are measured at amortized cost.

The Company recognizes an impairment loss if objective evidence of impairment loss exists. However, the impairment loss may be reversed if the value of asset recovers subsequently and the Company concludes the recovery is related to improvements in events or factors that originally caused the impairment loss. The new cost basis as a result of the reversal cannot exceed the amortized cost prior to the impairment.

c. Financial assets measured at cost

Unlisted stock, funds, and other securities without reliable market prices are measured at cost. When objective evidence of impairment exists, the Company recognizes an impairment loss, which cannot be reversed in subsequent periods.

d. Available-for-sale financial assets

Available-for-sale financial assets are non-derivative financial instruments not classified as financial assets at fair value through profit or loss, held-to-maturity financial assets, loans and receivables. Subsequent measurement is calculated at fair value. Investments in listed companies are measured at closing prices as of the balance sheet date. Any gain or loss arising from the change in fair value, excluding impairment loss and exchange gain or loss arising from monetary financial assets denominated in foreign currencies, is recognized as an adjustment to stockholders equity until such investment is reclassified or disposed of, upon which the cumulative gain or loss previously charged to stockholders equity will be recorded in the statement of income.

The Company recognizes an impairment loss when objective evidence of impairment exists. Any reduction in the impairment loss of equity investments in subsequent periods will be recognized as an adjustment to stockholders equity. The impairment loss of a debt security may be reversed and recognized in the current periods statement of income if the security recovers and the Company concludes the recovery is related to improvements in the factors or events that originally caused the impairment.

Allowance for Doubtful Accounts

An allowance for doubtful accounts is provided based on managements judgment of the collectibility and aging analysis of accounts and other receivables.

Inventories

Inventories are accounted for on a perpetual basis. Raw materials are recorded at actual purchase costs, while the work in process and finished goods are recorded at standard costs and subsequently adjusted to actual costs using the weighted-average method at the end of each month. Inventories are stated individually by category at the lower of aggregate cost or market value as of the balance sheet date. The market values of raw materials and supplies are determined on the basis of replacement cost while the market values of work in process and finished goods are determined by net realizable values. An allowance for loss on decline in market value or obsolescence is provided, when necessary.

Long-term Investments Accounted for Under the Equity Method

Long-term investments are recorded at acquisition cost. Investments acquired by contribution of technological know-how are credited to deferred credits among affiliates, which will be amortized over a period of 5 years.

Investments in which the Company has ownership of at least 20% or exercises significant influence on operating decisions are accounted for under the equity method. Prior to January 1, 2006, the difference of the acquisition cost and the underlying equity in the investees net assets as of acquisition date was amortized over 5 years; however, effective January 1, 2006, goodwill arising from new acquisitions is analyzed and accounted for under the ROC SFAS No. 25, Business Combination Accounting Treatment under Purchase Method, where goodwill is not subject to amortization.

The change in the Companys proportionate share in the net assets of an investee resulting from its acquisition of additional stock issued by the investee at a rate not proportionate to its existing equity ownership is charged to the additional paid-in capital and long-term investments accounts.

Unrealized intercompany gains and losses arising from sales from the Company to equity method investees are eliminated in proportion to the Companys ownership percentage at end of period until realized through transactions with third parties. Intercompany gains and losses arising from transactions between the Company and majority-owned (above 50%) subsidiaries are eliminated entirely until realized through transactions with third parties.

Unrealized intercompany gains and losses due to sales from equity method investees to the Company are eliminated in proportion to the Companys weighted-average ownership percentage of the investee until realized through transactions with third parties.

Unrealized intercompany gains and losses arising from transactions between two equity method investees are eliminated in proportion to the Companys multiplied weighted-average ownership percentage with the investees until realized through transactions with third parties. Those intercompany gains and losses arising from transactions between two majority-owned subsidiaries are eliminated in proportion to the Companys weighted-average ownership percentage in the subsidiary that incurred the gain or loss.

If the recoverable amount of investees accounted for under the equity method is less than its carrying amount, the difference is to be recognized as impairment loss in the current period.

The total value of an investment and related receivables cannot be negative. If, after the investment loss is recognized, the net book value of the investment is less than zero, the investment is reclassified to other liabilities on the balance sheet.

The Company ceases to use the equity method upon a loss of ability to exercise significant influence over an investee. In accordance with ROC SFAS No. 34, Financial Instrument: Recognition and Measurement, the carrying value of the investment upon the loss of significant influence remains as the carrying value of the investment. Any amount of the investees additional paid-in capital and other adjustment items under stockholders equity recorded in the stockholders equity of the Company are eliminated in proportion to the amount of the investment sold and recorded as gain or loss on disposal of investments. Cash dividends received during the year of change would be applied as a reduction of the carrying amount of the investment. Dividends received in subsequent years are recorded in accordance with ROC SFAS No. 32, Accounting for Revenue Recognition.

Gain or loss on disposal of long-term investments is based on the difference between selling price and book value of investments sold. Any amount of the investees additional paid-in capital and other adjustment items under stockholders equity recorded in the stockholders equity of the Company are eliminated in proportion to the amount of the investment sold and recorded as gain or loss on disposal of investments.

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. Maintenance and repairs are charged to expense as incurred. Significant renewals and improvements are treated as capital expenditures and are depreciated over their estimated useful lives. Upon disposal of property, plant and equipment, the original cost and accumulated depreciation are written off and the related gain or loss is classified as non-operating income or expense. Idle assets are classified as other assets at the lower of net book or net realizable value, with the difference charged to non-operating expenses.

Depreciation is recognized on a straight-line basis using the estimated economic life of the assets. The estimated economic life of the property, plant and equipment is as follows: buildings 20 to 55 years; machinery and equipment 5 years; transportation equipment 5 years and furniture and fixtures 5 years.

Intangible Assets

Effective January 1, 2006, goodwill generated from business combinations is no longer subject to amortization.

An impairment loss will be recognized when the decreases in fair value of intangible assets are other than temporary. The book value after recognizing the impairment loss is recorded as the new cost.

Deferred Charges

Deferred charges are stated at cost and amortized on a straight-line basis as follows: intellectual property license fees - the shorter of contract term or estimated economic life of the related technology; and software - 3 years.

Prior to December 31, 2005, the issuance costs of convertible and exchangeable bonds were classified as deferred charges and amortized over the life of the bonds. Effective January 1, 2006, the unamortized amounts as of December 31, 2005 were reclassified as a bond discount and recorded as a deduction to bonds payable. The amounts are amortized using the effective interest method over the remaining life of the bonds. If the difference between the straight-line method and the effective interest method is immaterial, the amortization of the bond discount may be amortized using the straight-line method and recorded as interest expenses.

Convertible and Exchangeable Bonds

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

When convertible bondholders exercise their conversion rights, the book value of the bonds is credited to common stock at an amount equal to the par value of the common stock with the excess credited to additional paid-in capital. No gain or loss is recognized upon bond conversion.

When exchangeable bondholders exercise their right to exchange their bonds for reference shares, the book value of the bonds is offset against the book value of the investments in reference shares and the related stockholders equity accounts, with the difference recognized as a gain or loss on disposal of investments.

In accordance with ROC SFAS No. 34, Financial Instruments: Recognition and Measurement, effective as of January 1, 2006, since the economic and risk characteristics of the embedded derivative instrument and the host contract are not clearly and closely related, derivative financial instruments embedded in exchangeable bonds shall be bifurcated and accounted as financial liabilities at fair value through profit or loss.

Pension Plan

All regular employees are entitled to a defined benefit pension plan that is managed by an independently administered pension fund committee. Fund assets are deposited under the committees name in the Bank of Taiwan and hence, not associated with the Company. Therefore, fund assets are not to be included in the Companys financial statements. Pension benefits for employees of the Branch are provided in accordance with the local regulations.

The Labor Pension Act of the R.O.C. (the Act), which adopts a defined contribution plan, became effective on July 1, 2005. Employees subject to for the Labor Standards Law, a defined benefit plan, were allowed to choose to either elect the pension calculation under the Act or continue to be subject to the pension calculation under the Labor Standards Law. Those employees that elected to be subject to the Act will have their seniority achieved under the Labor Standards Law retained upon election of the Act, and the Company will make monthly contributions of no less than 6% of these employees monthly wages to the employees individual pension accounts.

The accounting for the Companys pension liability is computed in accordance with ROC SFAS No. 18. Net pension costs of the defined benefit plan are recorded based on an independent actuarial valuation. Pension cost components such as service cost, interest cost, expected return on plan assets, the amortization of net obligation at transition, pension gain or loss, and prior service cost, are all taken into consideration. The Company recognizes expenses from the defined contribution pension plan in the period in which the contribution becomes due.

Employee Stock Option Plan

The Company used the intrinsic value method to recognize compensation cost for its employee stock options issued between January 1, 2004 and December 31, 2007, in accordance with Accounting Research and Development Foundation interpretation Nos. 92-070~072. For options granted on or after January 1, 2008, the Company recognizes compensation cost using the fair value method in accordance with ROC SFAS No. 39 Accounting for Share-Based Payment.

Share-Based Employee Bonuses and Remunerations Paid to Directors and Supervisors

In accordance with Accounting Research and Development Foundation interpretation No. 96-052 effective January 1, 2008, share-based employee bonuses and remunerations paid to directors and supervisors are charged to expense at fair value and are no longer accounted for as a reduction of retained earnings.

Treasury Stock

In accordance with ROC SFAS No. 30, Accounting for Treasury Stock, treasury stock held by the Company is accounted for under the cost method. The cost of treasury stock is shown as a deduction to stockholders equity, while any gain or loss from selling treasury stock is treated as an adjustment to additional paid-in capital. Prior to December 31, 2007, treasury stock transferred to employees was accounted as treasury stock transaction and no compensation expense is recorded. The Companys stock held by its subsidiaries is also treated as treasury stock. Cash dividends received by subsidiaries from the Company are recorded as additional paid-in capital - treasury stock transactions.

Revenue Recognition

The Company recognizes revenue when persuasive evidence of an arrangement exists, the product or service has been delivered, the sellers price to the buyer is fixed or determinable and collectability is reasonably assured. Most of the Companys sales transactions have shipping terms of Free on Board (FOB) or Free Carrier (FCA) shipment in which title and the risk of loss or damage is transferred to the customer upon delivery of the product to a carrier approved by the customer.

Allowance for sales returns and discounts are estimated based on history of customer complaints, historical experiences, management judgment and any other known factors that might significantly affect collectability. Such allowances are recorded in the same period in which sales are made.

Research and Development Expenditures

Research and development expenditures are charged to expenses as incurred.

Capital Expenditure versus Operating Expenditure

Expenditures are capitalized when it is probable that the Company will receive future economic benefits associated with the expenditures.

Income Tax

The Company adopted ROC SFAS No. 22, Accounting for Income Taxes for inter-period and intra-period income tax allocation. The provision for income taxes includes deferred income tax assets and liabilities that are a result of temporary differences between carrying amounts of assets and liabilities for financial reporting purposes and the amounts used for income tax purposes, loss carry-forward and investment tax credits. A valuation allowance on deferred income tax assets is provided to the extent that it is more likely than not that the tax benefits will not be realized. A deferred tax asset or liability is classified as current or noncurrent in accordance with the classification of its related asset or liability. However, if a deferred tax asset or liability does not relate to an asset or liability in the financial statements, its classification is based on the expected reversal date of the temporary difference.

According to the ROC SFAS No. 12, Accounting for Income Tax Credits, the Company recognizes the tax benefit from the purchase of equipment and technology, research and development expenditure, employee training, and certain equity investment by the flow-through method.

Income tax (10%) on unappropriated earnings is recorded as expense in the year when the shareholders have resolved that the earnings shall be retained.

The Income Basic Tax Act of the R.O.C. (the IBTA) became effective on January 1, 2006. Set up by the Executive Yuan, the IBTA is a supplemental 10% tax that is payable if the income tax payable determined by the ROC Income Tax Act is below the minimum amount as prescribed by the IBTA. The IBTA is calculated based on taxable income as defined by the IBTA, which includes most income that is exempted from income tax under various legislations. The impact of the IBTA has been considered in the Companys income tax for the current reporting period.

Earnings per Share

Earnings per share is computed according to ROC SFAS No. 24, Earnings Per Share. Basic earnings per share is computed by dividing net income (loss) by the weighted-average number of common shares outstanding during the current reporting period. Diluted earnings per share is computed 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. Net income (loss) is also adjusted for interest and other income or expenses derived from any underlying dilutive share equivalents. The weighted-average of outstanding shares is adjusted retroactively for stock dividends and bonus share issues.

Asset Impairment

Pursuant to ROC SFAS No. 35, the Company assesses indicators of impairment for all its assets (except for goodwill) within the scope of the standard at each balance sheet date. If impairment is indicated, the Company compares the assets carrying amount with the recoverable amount of the assets or the cash-generating unit (CGU) associated with the asset and writes down the carrying amount to the recoverable amount where applicable. The recoverable amount is defined as the higher of fair value less the costs to sell, and the values in use. For previously recognized losses, the Company assesses at the balance sheet date if any indication that the impairment loss no longer exists or may have diminished. If there is any such indication, the Company recalculates the recoverable amount of the asset, and if the recoverable amount has increased as a result of the increase in the estimated service potential of the assets, the Company reverses the impairment loss so that the resulting carrying amount of the asset does not exceed the amount (net of amortization or depreciation) that would otherwise result had no impairment loss been recognized for the assets in prior years.

In addition, a goodwill-allocated CGU or group of CGUs is tested for impairment each year, regardless of whether impairment is indicated. If an impairment test reveals that the carrying amount, including goodwill, of CGU or group of CGUs is greater than its recoverable amount, it results in an impairment loss. The loss is first recorded against the CGUs goodwill, with any remaining loss allocated to other assets on a pro rata basis proportionate to their carrying amounts. The write-down of goodwill cannot be reversed in subsequent periods under any circumstances.

Impairment losses and reversals are classified as non-operating expenses and income, respectively.

ACCOUNTING CHANGE

Employee Stock Options

Effective January 1, 2008, the Company adopted ROC SFAS No. 39, Accounting for Share-Based Payment to account for share-based payments. This change in accounting principles had no effect net income or earnings per share for the three-month period ended March 31, 2008.

Share-Based Employee Bonuses and Remunerations Paid to Directors and Supervisors

Effective January 1, 2008, the Company adopted Accounting Research and Development Foundation interpretation No. 96-052 to account for share-based employee bonuses and remunerations paid to directors and supervisors. The adoption resulted in an unfavorable effect to net income in the amount of NT$54 million, thereby reducing earnings per share by NT$0.004 for the three-month period ended March 31, 2008.

The board of directors shall make the distribution proposal annually and present it at the shareholders meeting.

(4) On February 15, 2005, the Hsinchu District Prosecutors Office conducted a search of the Companys facilities. On February 18, 2005, the Companys former Chairman Mr. Robert H.C. Tsao, released a public statement, explaining that its assistance to Hejian Technology Corp. (Hejian) did not involve any investment or technology transfer.

Furthermore, from the very beginning there was a verbal indication that, at the proper time, the Company would be compensated appropriately for its assistance, and circumstances permitting, at some time in the future, it will push through the merger between two companies. However, no promise was made by the Company and no written agreement was made and executed. Upon the Companys request to materialize the said verbal indication by compensating in the form of either cash or equity, the Chairman of the holding company of Hejian offered 15% of the approximately 700 million outstanding shares of the holding company of Hejian in return for the Companys past assistance and for continued assistance in the future.

Immediately after the Company had received such offer, it filed an application with the Investment Commission of the Ministry of Economic Affairs on March 18, 2005 (Ref. No. 94-Lian-Tung-Tzu-0222), for their executive guidance for the successful transfer of said shares to the Company. The shareholders meeting dated June 13, 2005 resolved that to the extent permitted by law the Company shall try to get the 15% of the outstanding shares offered by the holding company of Hejian as an asset of the Company. The holding company of Hejian offered 106 million shares of its outstanding common shares in return for the Companys assistance. The holding company of Hejian has put all such shares in escrow. The Company was informed of such escrow on August 4, 2006. The subscription price per share of the holding company of Hejian in the last offering was US$1.1. Therefore, the total market value of the said shares is worth more than US$110 million. However, the Company may not acquire the ownership of nor exercise the rights of the said shares with any potential stock dividend or cash dividend distributed in the future until the ROC laws and regulations allow the Company to acquire and exercise. In the event that any stock dividend or cash dividend is distributed, the Companys stake in the holding company of Hejian will accumulate accordingly.

In April 2005, the Companys former Chairman Mr. Robert H.C. Tsao was personally fined with in the aggregate amount of NT$3 million by the Financial Supervisory Commission, Executive Yuan, R.O.C. (ROC FSC) for failure to disclose material information relating to Hejian in accordance with applicable rules. As a result of the imposition of the fines by the ROC FSC, the Company was also fined in the amount of NT$30,000 by Taiwan Stock Exchange (TSE) for the alleged non-compliance with the disclosure rules in relation to the material information. The Company and its former Chairman Mr. Robert H.C. Tsao have filed for administrative appeal and reconsideration with the Executive Yuan, R.O.C. and TSE, respectively. Mr. Robert H.C. Tsaos administrative appeal was dismissed by the Execution Yuan, R.O.C. on February 21, 2006 and the ROC FSC transferred the case against Mr. Robert H.C. Tsao to the Administrative Enforcement Agency for enforcement of the fine. Mr. Robert H.C. Tsao has filed an administrative action against the ROC FSC with Taipei High Administrative Court on April 14, 2006. On December 27, 2007, the Administrative High Court revoked the decision and ruled in favor of Mr. Tsao.

For the Companys assistance to Hejian Technology Corp., the Companys former Chairman Mr. Robert H.C. Tsao, former Vice Chairman Mr. John Hsuan, and Mr. Duen-Chian Cheng, the General Manager of Fortune Venture Capital Corp., which is 99.99% owned by the Company, were indicted for violating the Business Entity Accounting Act and breach of trust under the Criminal Law by Hsinchu District Courts Prosecutors Office on January 9, 2006. Mr. Robert H.C. Tsao and Mr. John Hsuan had officially resigned from their positions of the Companys Chairman, Vice Chairman and directors prior to the announcement of the prosecution; for this reason, at the time of the prosecution, Mr. Robert H.C. Tsao and Mr. John Hsuan no longer served as the Companys directors and had not executed their duties as the Companys Chairman and Vice Chairman.

In the future, if a guilty judgment is pronounced by the court, such consequences would be Mr. Robert H.C. Tsao, Mr. John Hsuan and Mr. Duen-Chian Chengs personal concerns only; the Company would not be subject to indictment regarding this case. Mr. Robert H.C. Tsao, Mr. John Hsuan and Mr. Duen-Chian Cheng were pronounced innocent of the charge by Hsinchu District Court on October 26, 2007. On November 15, 2007, Taiwans Hsinchu District Court Prosecutors Office filed an appeal, which is currently under trial.

On February 15, 2006, the Company was fined in the amount of NT$5 million for unauthorized investment activities in Mainland China, implicating violation of Article 35 of the Act Governing Relations Between Peoples of the Taiwan Area and the Mainland Area by the R.O.C. Ministry of Economic Affairs (MOEA). However, as the Company believes it was illegally and improperly fined, the Company had filed an administrative appeal against MOEA to the Executive Yuan on March 16, 2006. On October 19, 2006, Executive Yuan denied the administrative appeal filed by the Company. The Company had filed an administrative litigation case against MOEA on December 8, 2006. Taipei High Administrative Court announced and reversed MOEAs administrative sanction on July 19, 2007. MOEA filed an appeal against the Company on August 10, 2007.

OTHERS

(1) Certain comparative amounts have been reclassified to conform to the current years presentation.

(2) Financial risk management objectives and policies

The Companys principal financial instruments, other than derivatives, is comprised of cash and cash equivalents, common stock, preferred stock, convertible bonds, open-end funds, bank loans, and bonds payable. The main purpose of these financial instruments is to manage financing for the Companys operations. The Company also holds various other financial assets and liabilities such as accounts receivable and accounts payable, which arise directly from its operations.

The Company also enters into derivative transactions, including credit-link deposits, interest rate swaps and forward currency contracts. The purpose of these derivative transactions is to mitigate interest rate risk and foreign currency exchange risks arising from the Companys operations and financing activities.

The main risks arising from the Companys financial instruments include cash flow interest rate risk, foreign currency risk, commodity price risk, credit risk, and liquidity risk.

Cash flow interest rate risk

The Company utilizes interest rate swap agreements to avoid its cash flow interest rate risk on the counter-floating rate of its unsecured domestic bonds issued during the period from May 21 to June 24, 2003. The terms of the interest rate swap agreements are the same as those of the domestic bonds, which are five and seven years. The floating rate is reset annually.

Foreign currency risk

The Company has foreign currency risk arising from purchases or sales. The Company utilizes spot or forward contracts to avoid foreign currency risk. The notional amounts of the foreign currency contracts are the same as the amount of the hedged items. In principal, the Company does not carry out any forward contracts for uncertain commitments.

Commodity price risk

The Companys exposure to commodity price risk is minimal.

Credit risk

The Company trades only with established and creditworthy third parties. It is the Companys policy that all customers who wish to trade on credit terms are subject to credit verification procedures. In addition, receivable balances are monitored on an ongoing basis, which consequently minimizes the Companys exposure to bad debts.

With respect to credit risk arising from the other financial assets of the Company, which is comprised of cash and cash equivalents, available-for-sale financial assets and certain derivative instruments, the Companys exposure to credit risk arising from the default of counter-parties is limited to the carrying amount of these instruments.

Although the Company trades only with established third parties, it will request collateral to be provided by third parties with less favorable financial positions.

Liquidity risk

The Companys objective is to maintain a balance of funding continuity and flexibility through the use of financial instruments such as cash and cash equivalents, bank loans and bonds.

b. The methods and assumptions used to measure the fair value of financial instruments are as follows:

i. The book values of short-term financial instruments approximate their fair value due to their short maturities. Short-term financial instruments include cash and cash equivalents, notes receivable, accounts receivable, current portion of capacity deposits, and payables.

ii. The fair value of financial assets at fair value through profit or loss and available-for-sale financial assets are based on the quoted market prices. If there are restrictions on the sale or transfer of an available-for-sale financial asset, the fair value of the asset will be determined based on similar but unrestricted financial assets quoted market price with appropriate discounts for the restrictions.

iii. The fair value of held-to-maturity financial assets and long-term investments accounted for under equity method are based on the quoted market prices. If market prices are unavailable, the Company estimates the fair value based on the book values.

iv. The fair value of financial assets measured at cost and prepayment for long-term investments are unable to be estimated since there is no active market in trading those unlisted investments.

v. The fair value of deposits-out is based on their book value since the deposit periods are principally within one year and renewed upon maturity.

vi. The fair value of bonds payable is determined by the market price.

vii. The fair value of derivative financial instruments is based on the amount the Company expects to receive (positive) or to pay (negative) assuming that the contracts are settled in advance at the balance sheet date.

c. The fair value of the Companys financial instruments is determined by the quoted prices in active markets, or if the market for a financial instrument is not active, the Company establishes fair value by using a valuation technique:

Non-derivative Financial Instruments	Active Market Quotation — 2008.03.31	2007.03.31	Valuation Technique — 2008.03.31	2007.03.31

(4) During the three-month period ended March 31, 2008, the Company held credit-linked deposits and repackage bonds that were recorded as held-to-maturity financial assets for the earning of interest income. The details are disclosed as follows:

a. Principal amount in original currency

As of March 31, 2007

Credit-linked deposits and repackage bonds referenced to	Amount		Due Date
ADVANCED SEMICONDUCTOR ENGINEERING INC. European Convertible Bonds and Loans	NTD	200 million	2007.09.25

b. Credit risk

The counterparties of the above investments are major international financial institutions. The repayment in full of these investments 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 Company and its subsidiary, UMC JAPAN, may receive less than the full amount of these investments or nothing. The Company and its subsidiary, UMC JAPAN, have selected reference entities with high credit ratings to minimize the credit risk.

c. Liquidity risk

Early withdrawal is not allowed for the above investments unless called by the issuer. However, the anticipated liquidity risk is low since most of the investments will either have matured within two years, or are relatively liquid in the secondary market.

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 at the balance sheet date and the settlement date.

(5) The Company entered into interest rate swap and forward contracts for hedging the interest rate risk arising from the counter-floating rate of its domestic bonds and for hedging the exchange rate risk arising from the net assets or liabilities denominated in foreign currency. The company entered into these derivative financial instruments in connection with its hedging strategy to reduce the market risk of the hedged items and these financial instruments were not held for trading purpose. The relevant information on the derivative financial instruments entered into by the Company is as follows:

a. The Company utilized interest rate swap agreements to hedge its interest rate risks on the counter-floating rate of its unsecured domestic bonds issued during the period from May 21 to June 24, 2003. The terms of the interest rate swap agreements are the same as those of the domestic bonds, which are five and seven years. The floating rate is reset annually. The details of interest rate swap agreements are summarized as follows:

As of March 31, 2008 and 2007, the Company had the following interest rate swap agreements in effect:

Notional Amount	Contract Period	Interest Rate Received	Interest Rate Paid
NT$7,500 million	May 21, 2003 to June 24, 2008	4.0% minus USD 12-Month LIBOR	1.52%
NT$7,500 million	May 21, 2003 to June 24, 2010	4.3% minus USD 12-Month LIBOR	1.48%

b. The details of forward contracts entered into by the Company are summarized as follows:

Mar 31, 2008

Type	Notional Amount		Contract Period
Forward contracts	Sell US$	348 million	Feb 21, 2008 to May 6, 2008

The Company did not hold any forward contracts as of Mar 31, 2007.

c. Transaction risk

(a) Credit risk

There is no significant credit risk exposure with respect to the above transactions as the counter-parties are reputable financial institutions with good global standing.

(b) Liquidity and cash flow risk

The cash flow requirements on the interest rate swap agreements are limited to the net interest payables or receivables arising from the differences in the swap rates. The cash flow requirements on forward contracts are limited to the net difference between the forward and spot rates at the settlement date. Therefore, no significant cash flow risk is anticipated since the working capital is sufficient to meet the cash flow requirements.

Interest rate swap agreements and forward contracts are intended for hedging purposes. Gains or losses arising from the fluctuations in interest rates and exchange rates are likely to be offset against the gains or losses from the hedged items.

REVIEW REPORT OF INDEPENDENT ACCOUNTANTS

English Translation of a Report Originally Issued in Chinese

To United Microelectronics Corporation

We have reviewed the accompanying consolidated balance sheet of United Microelectronics Corporation and subsidiaries (the Company) as of March 31, 2008, and the related statement of income and cash flows for the three-month period ended March 31, 2008. These financial statements are the responsibility of the Companys management. Our responsibility is to issue the review report based on our review. As described in Note 3(8) to the consolidated financial statements, certain long-term investments were accounted for under the equity method based on financial statements as of March 31, 2008 of the investees, which were reviewed by the other auditors. Our review insofar as it relates to the investment loss amounted to NT$45 million for the three-month period ended March 31, 2008, and the related long-term investment balance of NT$4,255 million as of March 31, 2008, is based solely on the reports of the other auditors.

We conducted our review in accordance with the Statements of Auditing Standards No. 36, Review of Financial Statements of the Republic of China. A review is limited primarily to applying analytical procedures to financial data and making inquiries of persons responsible for financial and accounting matters. It is substantially less in scope than an audit conducted in accordance with generally accepted auditing standards, the objective of which is the expression of an opinion regarding the financial statements taken as a whole. Accordingly, we do not express such an opinion.

Based on our review and the reports of the other auditors, we are not aware of any material modifications or adjustments that should have been made to the consolidated financial statements referred to above in order for them to be in conformity with requirements of the Business Entity Accounting Act and Regulation on Business Entity Accounting Handling with respect to financial accounting standards, Guidelines Governing the Preparation of Financial Reports by Securities Issuers, the order VI-0960064020 issued by Financial Supervisory Commission, Executive Yuan, and accounting principles generally accepted in the Republic of China.

As described in Note 2 to the consolidated financial statements, effective January 1, 2008, the Company adopted Accounting Research and Development Foundation Interpretation No. 96-052, and recognized share-based employee bonuses and remunerations to directors and supervisors as expenses rather than as a distribution of retained earnings.

March 31, 2008

(Expressed in Thousands of New Taiwan Dollars unless Otherwise Specified)

United Microelectronics Corporation and the consolidated entities (the Company) has prepared the notes in conformity with the order VI-0960064020 issued by Financial Supervisory Commission, Executive Yuan as of November 15, 2007, which simplifies the disclosure requirement. According to this order, the Company is only required to disclose the differences of accounting policies between the latest audited consolidated financial statements and the current ones and to disclose the consolidated entities. The following items can be exempt from disclosures:

i. History and organization;

ii. Income tax;

iii. Pension plan;

iv. Summary of operation cost and expenses including salary, depreciation, depletion, and amortization; and

v. Attachments pertaining to significant transactions, investments, and investments in Mainland China.

SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

The consolidated financial statements were prepared in conformity with requirements of the Business Entity Accounting Act and Regulation on Business Entity Accounting Handling with respect to financial accounting standards, the order VI-0960064020 issued by Financial Supervisory Commission under the Executive Yuan, Guidelines Governing the Preparation of Financial Reports by Securities Issuers and accounting principles generally accepted in the Republic of China (R.O.C.).

Significant accounting policies adopted in preparing the accompanying consolidated financial statements are those adopted in preparing the annual consolidated financial statements of 2007, except those stated below:

(1) General Description of the Reporting Entities

a. Principles of Consolidation

Investees in which United Microelectronics Corporation (UMC), directly or indirectly, holds more than 50% of voting rights or de facto control with less than 50% of voting rights, are consolidated into UMCs financial statements.

Transactions between consolidated entities are eliminated in the consolidated financial statements. Prior to January 1, 2006, the difference between the acquisition cost and the net equity of a subsidiary as of the acquisition date was amortized over 5 years; however effective January 1, 2006, goodwill arising from new acquisitions is analyzed and accounted for under the ROC Statement of Financial Accounting Standard (SFAS) No. 25, Business Combination Accounting Treatment under Purchase Method, and goodwill is not subject to amortization.

b. The consolidated entities are as follows:

(2) Employee Stock Option Plan

The Company used the intrinsic value method to recognize compensation cost for its employee stock options issued between January 1, 2004 and December 31, 2007, in accordance with Accounting Research and Development Foundation interpretations No. 92-070 through 072. For stock options granted on or after January 1, 2008, the Company recognizes compensation cost using the fair value method in accordance with ROC SFAS No. 39 Accounting for Share-Based Payment.

(3) Share-Based Employee Bonuses and Remunerations Paid to Directors and Supervisors

In accordance with Accounting Research and Development Foundation interpretation No. 96-052 effective January 1, 2008, share-based employee bonuses and remunerations paid to directors and supervisors are accounted for as expenses and charged to current income at fair value rather than as a reduction of retained earnings.

ACCOUNTING CHANGES

(1) Employee Stock Options

Effective January 1, 2008, the Company adopted ROC SFAS No. 39, Accounting for Share-Based Payment to account for share-based payments. This change in accounting principles had no effect on consolidated net income or on consolidated earnings per share for the three-month period ended March 31, 2008.

(2) Share-Based Employee Bonuses and Remunerations Paid to Directors and Supervisors

Effective January 1, 2008, the Company adopted Accounting Research and Development Foundation interpretation No. 96-052 to account for share-based employee bonuses and remunerations paid to directors and supervisors. The adoption resulted in an unfavorable effect on consolidated net income in the amount of NT$54 million, thereby reducing consolidated earnings per share by NT$0.004 for the three-month period ended March 31, 2008.

b. Offset prior years operation losses;

c. Set aside 10% of the remaining amount after deducting items (a) and (b) as a legal reserve;

Employees of UMCs subsidiaries, meeting certain requirements determined by the board of directors, are also eligible for the employees bonus.

f. The distribution of the remaining portion, if any, will be recommended by the board of directors and resolved in the shareholders meeting.

During the three-month period ended March 31, 2008, the amounts of the employee bonuses and remunerations to directors and supervisors were estimated at NT$84 million and NT$1 million, respectively. The board of directors estimated the amount by taking into consideration the Companys Articles of Incorporation, government regulations and industrial average. Estimated employee bonuses and remunerations to directors and supervisors were charged to current income. If the board modifies the estimates significantly in the subsequent periods during the year, the Company will recognize the change as an adjustment to current income in the period the modification is made. Moreover, if the amounts were modified by the shareholders meeting of the following year, the adjustment will be regarded as a change of accounting estimate and will be reflected in the consolidated statement of income in the following year.
