The Board of Directors and Shareholders
Taiwan Semiconductor Manufacturing Company Ltd.

We have reviewed the accompanying balance sheets of Taiwan Semiconductor
Manufacturing Company Ltd. as of March 31, 2003 and 2002, and the related
statements of income and cash flows for the three months then ended. These
financial statements are the responsibility of the Company's management. Our
responsibility is to issue a report on these financial statements based on our
reviews.

We conducted our reviews in accordance with Statement on Auditing Standards No.
36 "Review of Financial Statements" issued by the Auditing Committee of the
Accounting Research and Development Foundation of the Republic of China. A
review consists principally of 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 auditing standards generally accepted in the Republic of China,
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, we are not aware of any material modifications that should
be made to the financial statements referred to above for them to be in
conformity with the Guidelines for Securities Issuers' Financial Reporting and
accounting principles generally accepted in the Republic of China.

                                     - 1 -



As disclosed in Note 3 to the financial statements, the Company adopted
Statement of Financial Accounting Standards ("SFAS") No. 30, "Accounting for

record stock held by its subsidiary as treasury stock.

practices to audit such financial statements are those generally accepted and

                TAIWAN SEMICONDUCTOR MANUFACTURING COMPANY LTD.

                         NOTES TO FINANCIAL STATEMENTS
                                  (Unaudited)
     (Amounts in Thousand New Taiwan Dollars, Unless Specified Otherwise)

1. GENERAL

   Taiwan Semiconductor Manufacturing Company Ltd. (the "Company" or "TSMC"), a
   Republic of China corporation, was incorporated as a venture among the
   Government of the Republic of China, acting through the Development Fund of
   the Executive Yuan; Philips Electronics N.V. and certain of its affiliates
   (Philips); and certain other private investors. In September 1994, its
   shares were listed on the Taiwan Stock Exchange. On October 8, 1997, TSMC
   listed its shares of stock on the New York Stock Exchange in the form of
   American Depositary Shares.

   TSMC is engaged mainly in the manufacturing, selling, packaging, testing and
   designing of integrated circuits and other semiconductor devices, and the
   manufacturing of masks.

2. SIGNIFICANT ACCOUNTING POLICIES

   The financial statements are presented in conformity with the Guidelines for
   Securities Issuers' Financial Reporting and accounting principles generally
   accepted in the Republic of China. Significant accounting policies are
   summarized as follows:

   Classification of current and non-current assets and liabilities

   Current assets are those expected to be converted to cash, sold or consumed
   within one year. Current liabilities are obligations due on demand within
   one year from the balance sheet date. Assets and liabilities that are not
   classified as current are non-current assets and liabilities, respectively.

   Cash equivalents

   Government bonds acquired with maturities less than three months from the
   date of purchase are classified as cash equivalents.

   Short-term investments

   Short-term investments are carried at the lower of cost or market value. The
   costs of investments sold are determined by the specific identification
   method.

   Allowance for doubtful receivables

   Allowance for doubtful receivables are provided based on a review of the
   collectibility of accounts receivables.

                                     - 8 -



   Revenue recognition and allowance for sales returns and others

   The four criteria that we use to recognize revenue are the existence of
   evidence of a contractual arrangement, delivery or performance has occurred,
   the selling price is fixed or determinable and collectibility is reasonably
   assured. Allowance for sales returns and others is estimated based on
   historical experience. Such provisions are deducted from sales in the year
   the products are sold and the estimated related costs are deducted from cost
   of sales.

   Sales are determined using the fair value taking into account related sales
   discounts agreed to by the Company and customer. Since the receivables from
   sales are collectible within one year and such transactions are frequent,
   the fair value of receivables is equivalent to the nominal amount of cash
   received.

   Inventories

   Inventories are stated at the lower of cost or market value. Inventories are
   recorded at standard cost and adjusted to approximate weighted-average cost
   at the end of each period. Market value represents net realizable value for
   finished goods and work in process, and replacement value for raw materials,
   supplies and spare parts.

   Long-term investments

   Investments in shares of stock of companies wherein the Company exercises
   significant influence on the operating and financial policy decisions are
   accounted for using the equity method. The Company's proportionate share in
   the net income or net loss of investee companies are recognized as
   components of the "Investment income/loss recognized by equity method - net"
   account. The Company adopted Statements of Financial Accounting Standards
   ("SFAS") No. 30, "Accounting for Treasury Stock" on January 1, 2002. SFAS
   No. 30 requires a parent company to record stock held by its subsidiary as
   treasury stock. When acquiring shares of stock, the difference between cost
   of investment and its book value is amortized using straight-line method
   over five years.

   When the Company subscribes to additional investee shares at a percentage
   different from its existing equity interest, the resulting carrying amount
   of the investment in equity investee differs from the amount of Company's
   proportionate share in the investee's net equity. The Company records such
   difference as an adjustment to "capital surplus" as well as the "long-term
   investments" accounts. In the event an investee has an accumulated deficit,
   it will record an offset to its capital surplus, excluding the reserve for
   asset revaluation, through retained earnings. The Company will also record a
   corresponding entry equivalent to its proportionate share of the investee
   capital surplus, excluding the reserve for asset revaluation, that was
   generated subsequent to any acquisition of equity interest in the investee.
   If an investee's functional currency is a foreign currency, "cumulative
   translation adjustments" would result from the process of translating the
   investees' financial statements into the functional currency of the Company.

                                     - 9 -



   Other stock investments are accounted for using the cost method. Cash
   dividends are recognized as income in the year received but are accounted
   for as reduction in the carrying values of the long-term investments if the
   dividends are received in the same year that the related investments are
   acquired. Stock dividends are recognized neither as investment income nor
   increase of long-term investment but recorded only as an increase in the
   number of shares held. An allowance is recognized for any decline in the
   market value of investments using quoted market prices with the
   corresponding amount charged to shareholders' equity. A reversal of the
   allowance will result from a subsequent recovery of the market value. The
   carrying values of investments with no quoted market price are reduced to
   reflect an other than temporary decline in their values with the related
   impairment loss charged to income.

   Investments in foreign mutual funds are stated at the lower of aggregate
   cost or net asset value (NAV). An allowance is recognized when the cost of
   the funds are lower than their net asset values, with the corresponding
   amount charged to shareholders' equity. A reversal of the allowance will
   result from a subsequent recovery of the net asset value.

   The costs of investments sold are determined using the weighted-average
   method.

   If an investee company has an unrealized loss on a long-term investment
   evaluated using the lower-of-cost-or-market method, the Company recognizes a
   corresponding unrealized loss in proportion to its equity interest and
   records the amount as a component of its own shareholders' equity.

   Gains or losses on transactions with investee companies wherein the Company
   owns at least 20% of the outstanding common stock but less than a
   controlling interest are deferred in proportion to the Company's ownership
   percentage until such gains or losses are realized through a transaction
   with a third party. The entire amount of gains or losses on sales to
   majority-owned subsidiaries are deferred until such gains or losses are
   realized through a subsequent transaction with a third party. Gains or
   losses from sales by investee companies to the Company are deferred in
   proportion to the ownership percentage until realized through transactions
   with third parties.

   Property, plant and equipment, assets leased to others and idle assets

   Property, plant and equipment and assets leased to others are stated at cost
   less accumulated depreciation. Idle assets are stated at the lower of book
   value or net realizable value. Significant additions, renewals, betterments
   and interest expense incurred during the construction period are
   capitalized. Maintenance and repairs are expensed in the period incurred.
   Property, plant and equipment covered by agreements qualifying as capital
   leases are carried at the lower of the present value of future minimum rent
   payments, or the market value of the property at the inception date of the
   lease. The lessee's periodic rent payment includes the purchase price of the
   leased property and the interest expense.

   Depreciation is computed using the straight-line method over the following
   estimated service lives: buildings - 10 to 20 years; machinery and equipment
   - 5 years; and office equipment - 3 to 5 years.

   Upon sale or disposal of property, plant and equipment, the related cost and
   accumulated depreciation are removed with any gains or losses credited or
   charged to income in the period of disposal.

                                    - 10 -



   Goodwill

   Goodwill represents the excess of the consideration paid for acquisition
   over the fair market value of net identifiable assets acquired. Goodwill is
   amortized using the straight-line method over the estimated life of 10 years.

   Deferred charges

   Deferred charges consist of software and system design costs, technology
   know-how, bond issuance costs, and technology license fees. The amounts are
   amortized as follows: Software and system design costs - 3 years, technology
   know-how - 5 years, bond issuance costs - the term of the bonds, technology
   license fee - the shorter of the estimated life of the technology or the
   term of the technology transfer contract.

   Pension costs

   Net periodic pension costs are recorded on the basis of actuarial
   calculations. Unrecognized net transition obligation and unrecognized net
   gain/loss are amortized over 25 years.

   Deferred gain on sale and leaseback

   The gain on the sale of property that is simultaneously leased back is
   deferred by the Company. This deferred gain on sales and leaseback
   transactions is amortized as follows: (a) operating leases - adjustment of
   rental expenses over the term of the leases and (b) capital leases -
   adjustment of depreciation expenses over the estimated useful life or term
   of the lease; whichever is shorter.

   Casualty loss

   Casualty losses mainly caused from the March 31, 2002 earthquake are
   recorded when incurred and any insurance recoveries are recorded when
   probable up to the amount of the loss. Recoveries in excess of the amount of
   the loss are recorded when realized.

   Income tax

   The Company uses an inter-period tax allocation method for income tax.
   Deferred income tax assets and liabilities are recognized for the tax
   effects of temporary differences, unused tax credits, and operating loss
   carryforwards. Valuation allowances are provided to the extent, if any, that
   it is more likely than not that the deferred income tax assets will not be
   realized. A deferred tax asset or liability is classified as current or
   non-current according to 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, then it is classified as
   either current or non-current based on the expected length of time before it
   is realized.

   Any tax credit arising from the purchase of machinery, equipment and
   technology, research and development expenditures, personnel training,
   investments in important technology-based enterprise are recognized using
   the current method.

   Adjustments of prior years' tax liabilities are added to or deducted from
   the current year's tax provision.

                                    - 11 -



   As of January 1, 1998, income taxes on unappropriated earnings of 10% are
   expensed in the year of shareholder approval which is usually the year
   subsequent to the year of earnings.

   Derivative financial instruments

   The Company enters into foreign currency forward contracts to manage
   currency exposures in cash flow and in foreign currency-denominated assets
   and liabilities. The differences in the New Taiwan dollar amounts translated
   using the spot rate and the amounts translated using the contracted forward
   rates on the contract date are amortized over the terms of the forward
   contracts using the straight-line method. At the balance sheet dates, the
   receivables or payables arising from forward contracts are restated using
   the prevailing spot rate and the resulting differences are charged to
   income. Also, the receivables and payables related to the forward contract
   are netted with the resulting amount presented as either an asset or
   liability. Any resulting gain or loss upon settlement is credited or charged
   to income in the period of settlement.

   The Company enters into interest rate swap transactions to manage exposures
   from changes in interest rates on existing liabilities. These transactions
   are accounted for on an accrual basis, in which the cash settlement
   receivable or payable is recorded as an adjustment to interest income or
   expense.

   The notional amount of foreign currency option contracts entered into for
   hedging purposes are not recognized as an asset or liability on the contract
   dates. The premiums paid or received for the call or put options are
   amortized and charged to income on a straight-line basis over the term of
   the related contract. Any resulting gain or loss upon settlement is credited
   or charged to income in the period of settlement.

   Foreign-currency transactions

   Foreign-currency transactions are recorded in New Taiwan dollars at the
   current rate of exchange in effect when the transaction occurs. Gains or
   losses derived from foreign currency transactions or monetary assets and
   liabilities denominated in a foreign currency are recognized in current
   operations. At the end of each period, foreign-currency assets and
   liabilities are revalued at the prevailing exchange rate with the resulting
   gains or losses recognized in current operation.

   Reclassification

   Certain accounts in the financial statement as of and for the three months
   ended March 31, 2002 have been reclassified to conform to the financial
   statements as of and for the three months ended March 31, 2003.

3. NEW ACCOUNTING PRONOUNCEMENTS

   In accordance with the Statement of Financial Accounting Standards ("SFAS")
   No. 30, "Accounting for Treasury Stock" and other relevant regulations from
   Securities and Futures Commission (SFC), the Company is required to
   reclassify its common stock held by subsidiaries from short/long-term
   investments to treasury stock. The reclassification is based on the carrying
   value recorded by the Company's subsidiaries as of January 1, 2002. The
   adoption of SFAS No. 30 resulted in the decrease of long-term investments
   and the increase of treasury stock by NT$2,103,921 thousand as of March 31,
   2002, and a decrease in net income for the three months ended March 31, 2002
   by and NT$30,539 thousand.

14. SHAREHOLDERS' EQUITY

   The Company has 369,019 thousand American Depositary Shares (ADS) issued on
   the New York Stock Exchange as of March 31, 2003. The number of common
   shares represented by the ADSs is 1,845,097 thousand shares (one ADS
   represents five common shares).

   Capital surplus can only be used to offset a deficit under the ROC Company
   Law. However, the components of capital surplus generated from donations
   (donated capital) and the excess of the issue price over the par value of
   capital stock (including the stock issued for new capital, mergers, and the
   purchase of treasury stock) can be transferred to capital as stock dividends.

   The Company's Articles of Incorporation provide that the following shall be
   appropriated from annual net income (less any cumulative deficit):

    a. 10% legal reserve;

    b. Special reserve in accordance with relevant laws or regulations;

    c. Remuneration to directors and supervisors and bonus to employees equal
       to 0.3% and at least 1% of the remainder, respectively. Individuals
       eligible for the employee bonus may include employees of affiliated
       companies as approved by the board of directors or a representative of
       the board of directors;

    d. Dividends to holders of preferred shares equal to a 3.5% annual rate,
       based on the period during which the preferred shares have been
       outstanding;

    e. The appropriation of the remaining balance after the above shall be
       decided at the shareholder's meeting.

   Dividends are distributed in cash, shares of common stock or a combination
   of cash and common stock. Distribution of profits are preferably made in the
   form of stock dividend. The total of cash dividends paid in any given year
   may not exceed 50% of total dividends distributed.

   Any appropriations of net income shall be approved at the shareholders'
   meeting in the following year and are recorded in the financial statement in
   the year of shareholder approval.

                                    - 21 -



The aforementioned appropriation for legal reserve shall be made until the
reserve is equal to the aggregate par value of the Company's outstanding
capital stock. The reserve can only be used to offset a deficit. When the
reserve balance has reached 50% of the aggregate par value of the outstanding
capital stock of the Company, the reserve can also be distributed as stock
dividend up to half of the reserve balance.

The appropriations from the earnings of 2002 and 2001 were approved in the
board of directors and shareholders' meeting on March 4, 2003 and May 7, 2002,
respectively. The appropriations and dividend per share are as follows:



                                                                      Dividend Per

The above appropriation of the earnings in fiscal year 2001 is consistent with
the resolution of the meeting of board of directors on March 26, 2002. If the
above employee bonus and remuneration to directors and supervisors were paid in
cash and charged against the income of 2002 and 2001, the basic EPS for the
years ended December 31, 2002 and 2001 would decrease from NT$1.14 to NT$1.05
and NT$0.83 to NT$0.76, respectively. The shares distributed as a bonus to
employees represented 0.83% and 0.64% of the Company's total outstanding common
shares as of December 31, 2002 and 2001, respectively.

The above information associated with the appropriations of bonus to employees
and remuneration to directors and supervisors is available at Market
Observation System website.

A special reserve equivalent to the debit balance of any account shown in the
shareholder's equity section of the balance sheet (except for the recorded cost
of treasury stock held by subsidiaries), shall be made from unappropriated
retained earnings pursuant to existing regulations promulgated by the
Securities and Futures Commission. The special reserve is allowed to be
appropriated to the extent that the debit balance of such accounts is reversed.

Under the Integrated Income Tax System that became effective on January 1,
1998, ROC resident shareholders are allowed a tax credit for the income tax
paid by the Company on earnings generated on or after January 1, 1998. An
Imputation Credit Account (ICA) is maintained by the Company for such income
tax and the tax credit allocated to each shareholder.

   The potential common shares from the employee stock option plan (see Note
   14) are not included in the denominator of the diluted earning-per-share
   computation because such shares result in a non-dilutive per share amount by
   using the treasury stock method under the Statement of Financial Accounting
   Standards No. 24, "Earning Per Share". The average number of shares
   outstanding for EPS calculation has been adjusted retroactively for issuance
   of stock dividends


                                    - 24 -



   and stock bonuses. The retroactive adjustment caused the basic EPS before
   income tax and after income tax for the three months ended March 31, 2002 to
   decrease from NT$0.41 to NT$0.37 and NT$0.39 to NT$0.35, respectively.

19. SIGNIFICANT COMMITMENTS AND CONTINGENCIES

   The significant commitments and contingencies of the Company as of March 31,
   2003 are as follows:

    a. Under a Technical Cooperation Agreement with Philips, as amended on May
       12, 1997, the Company shall pay technical assistance fees at a
       percentage of net sales (as defined in the agreement) of certain
       products. The agreement shall remain in force through July 8, 2007 and
       may be automatically renewed for successive periods of three years
       thereafter. Under the amended agreement, starting from the fifth
       anniversary date of the amended agreement, the fees are subject to
       reduction by the amounts the Company pays to any third party for
       settling any licensing/infringement disputes, provided that the reduced
       fee will not be below a certain percentage of the net sales.

    b. Subject to certain equity ownership and notification requirements,
       Philips and its affiliates can avail themselves each year of up to 30%
       of the Company's production capacity.

    c. Under a technical cooperation agreement with ITRI, the Company shall
       reserve and allocate up to 35% of certain of its production capacity for
       use by the Ministry of Economic Affairs (MOEA) or any other party
       designated by the MOEA.

    d. Under several foundry agreements, the Company shall reserve a portion of
       its production capacity for certain major customers who have made
       guarantee deposits to the Company. As of March, 31, 2003, the Company
       received a total of US$39,667 thousand of guarantee deposits.

    e. Under a Shareholders Agreement entered into with Philips and EDB
       Investments Pte Ltd. on March 30, 1999, the parties formed a joint
       venture company "SSMC" for the purpose of constructing an integrated
       circuit foundry in Singapore, and allow the Company to invest 32% of
       SSMC's capital. The Company and Philips committed to buy a specific
       percentage of the production capacity of SSMC. If any party defaults on
       the commitment and the capacity utilization of SSMC falls below a
       specific percentage of its total capacity, the defaulting party is
       required to compensate SSMC for all related unavoidable costs.

    f. The Company provides technical services to SSMC under a Technical
       Cooperation Agreement (the "Agreement") entered into on May 12, 1999.
       The Company receives compensation for such services computed at a
       specific percentage of net selling prices of certain products sold by
       SSMC. The Agreement remains in force for ten years and is automatically
       renewed for successive periods of five years unless pre-terminated by
       either party under certain conditions.

    g. The Company provided guarantees on loans amounting to US$200,000
       thousand, US$40,000 thousand and US$440,000 thousand for TSMC
       Development, Inc., TSMC - North America and WaferTech, LLC, respectively.

                                    - 28 -



    h. Under a Technology Transfer Agreement ("TTA") with National
       Semiconductor Corporation ("National") entered into on June 27, 2000,
       TSMC shall receive payments for license of certain technology to
       National. The agreement will remain in force for ten years and will be
       automatically renewed for successive periods of two years thereafter
       unless either party gives notice for early termination under certain
       conditions. In January 2003, the Company and National entered into a
       Termination Agreement whereby the TTA was terminated for convenience.
       Under the termination agreement, the Company will be relieved of any
       further obligation to transfer any additional technology. In addition,
       the Company granted National an option to request additional technology
       transfers under the same terms and conditions as the terminated TTA
       through January 2008.

    i. The Company entered into a Manufacturing Agreement with VIS. VIS agrees
       to reserve certain production capacity for the Company to manufacture
       certain logic devices or other technologies required by the Company's
       customers at selling prices agreed upon by the parties. The Company paid
       NT$1,200,000 thousand to VIS as a guarantee deposit. VIS shall return
       portions of the guarantee deposit without any interest to the Company
       upon reaching certain levels of purchase commitment by the Company. The
       contract will remain in force for five years. As of March 31, 2003, the
       refundable deposit was NT$450,666 thousand.

    j. Starting from 2001, the Company entered into several license

       b) Interest rate swaps

          The Company entered into interest rate swap contracts to hedge
          exposure from rising interest rates on its floating rate long-term
          loans. Interest expense on these transactions for the three months

       c) Option contracts

          The Company entered into foreign currency option contracts to hedge
          risks of exchange rate fluctuations arising from its anticipated U.S.
          dollar cash receipts from its export sales or its European currency
          obligations for purchases of machinery and equipment.

          Outstanding option contracts as of March 31, 2003 were as follows:



                               Contract
                                Amount     Credit

          For the three months ended March 31, 2003, the Company recognized
          premium income of NT$50,273 thousand and premium expense of NT$76,829
          thousand.

       d) Transaction risk

           i) Credit risk. Credit risk represents the positive net settlement
              amount of those contracts with positive fair value on the balance
              sheet date. The positive net settlement amount represents the
              loss incurred by the Company if the counter-parties breached the
              contracts. The banks, which are the counter-parties to the
              foregoing derivative financial instruments, are reputable
              financial institutions. Management believes its exposures related
              to the potential default by those counter-parties are low.

          ii) Market price risk. All derivative financial instruments are
              intended as hedges for fluctuations in currency exchange rates on
              the Company's foreign currency denominated receivables or
              payables and interest rate fluctuations on its floating rate
              long-term loans. Gains or losses from forward exchange contracts
              are likely to be offset by gains or losses from the hedged
              receivables and payables. Interest rate risks are also controlled
              as the expected cost of capital is fixed. Thus, market price
              risks are believed to be minimal.


                                    - 31 -



         iii) Liquidity and cash flow risk and uncertainty of amount and term
              of future cash demand

              As of March 31, 2003, the Company's future cash demand for
              outstanding forward exchange contracts, interest rate swaps and
              option contracts are as follows:



                                   Forward Exchange Contracts
                                   --------------------------
                        Term          Inflow       Outflow
                        ----       ------------- ------------
                                           
                   Within one year NT$34,684,658 US$1,084,200
                                   EUR    24,000
                                   JPY 6,823,385


              The Company has sufficient operating capital to meet the above
              cash demand. The interest rate of the interest rate swaps has
              taken the Company's cost of capital into account. In addition,
              the exchange rate of forward foreign exchange contracts and
              option contracts have been fixed. Therefore, there is no material
              fund raising risk and cash flow risk.

       2) Fair value of financial instruments:



                                                     March 31, 2003            March 31, 2002

                                    - 32 -



   Fair values of financial instruments were determined as follows:

    a) The carrying amounts reported in the balance sheets for cash and cash
       equivalents, notes and accounts receivable, other financial assets,
       accounts payable, payables to contractors and equipment suppliers are
       approximate to their fair values.

    b) Fair value of short-term and long-term investments is based on quoted
       market prices. If quoted market prices are unavailable, fair value is
       based on net worth or book value.

    c) Fair value of refundable deposits and guarantee deposits is based on
       carrying values.

    d) Bonds payable is discounted to present value. Fair value of other
       long-term payable is equivalent to its carrying value.

    e) Fair value of derivative financial instruments is the estimated net
       receivable (positive) or payable (negative) if those contracts are
       terminated on the relevant balance sheet date.

   The fair values of non-financial instruments were not included in the fair
   values disclosed above. Accordingly, the sum of the fair values of the
   financial instruments listed above does not represent the fair value of the
   Company as a whole.

3) Investment in Mainland China:

   The Company filed an investment project with the Investment Commission of
   MOEA to establish a foundry in Mainland China. On February 27, 2003, the
   authority approved phase one of the foregoing project and permitted direct
   investment in establishing TSMC - Shanghai. TSMC - Shanghai has not come
   into existence as of April 17, 2003.
