INDEPENDENT ACCOUNTANTS' REPORT

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 September 30, 2003 and 2002 and the related
statements of income and cash flows for the nine 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 of 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 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 reviews, 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 accounting principles generally accepted in the Republic of
China.

As disclosed in Note 3 to the financial statements, the Company adopted
Statement 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.

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; Koninklijke 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 (TSE). On October
     8, 1997, TSMC listed its shares of stock on the New York Stock Exchange
     (NYSE) in the form of American Depositary Shares (ADSs).

     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 from the balance sheet date. 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 under repurchase agreements 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 market values of funds and government bonds are determined by the net
     asset value of the open-end funds and the daily-volume-weighted-average
     yield/price conversion of GreTai Securities Market, respectively. 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. We determine the amount of
     allowance for doubtful accounts by examining our historical collection
     experience and current trends in the credit quality of our customers as
     well as our internal credit policies.

                                       -7-



     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, whether delivery or performance has
     occurred, whether the selling price is fixed or determinable and whether
     collectibility is reasonably assured. Allowance for sales returns and
     others is estimated based on historical experience and any known factors
     that would affect the allowance. 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 customers. 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. The scrap and slow-moving items are
     recognized as inventory reserve.

     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 is recognized as
     components of the "investment income/loss recognized by equity method--net"
     account. When acquiring shares of stock, the difference between the cost of
     investment and the Company's proportionate share of investee's net book
     value is amortized using straight-line method over five years, and is also
     recorded as a components of the "investment income/loss recognized by
     equity method--net". 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 reclassify its capital stock
     held by its subsidiaries from short/long-term investments to treasury
     stock.

     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 uses its capital surplus
     (excluding reserve for asset revaluation) to offset its accumulated
     deficit, the Company will also record a corresponding entry equivalent to
     its proportionate share of the investee's adjustment. If an investee's
     functional currency is a foreign currency, "cumulative translation
     adjustments" would result from the process of translating the investee's
     financial statements into the functional currency of the Company.

     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 investments 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 debited to shareholders' equity. A reversal of the
     allowance will result from a subsequent recovery of the market value of
     such investments. 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.

                                       -8-



     Investments in foreign mutual funds are stated at the lower of aggregate
     cost or net asset value. An allowance is recognized when the cost of the
     funds is lower than their net asset values, with the corresponding amount
     debited 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 realized through a transaction with a third party. The
     entire amount of the gains or losses on sales to majority-owned
     subsidiaries are deferred until such gains or losses are realized through
     the subsequent sale of the related products to third parties. 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. When significant impairment loss
     occurs, the related assets are stated at the lower of fair value or the
     book value. 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.

     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 from the corresponding accounts,
     and with any gain or loss is charged to income in the period of disposal.

     Goodwill

     Goodwill represents the excess of the consideration paid for acquisitions
     over the fair market value of identifiable net 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 are amortized over 25 years.

                                       -9-



     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: operating leases--adjustment of
     rental expenses over the term of the leases.

     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 net operating loss
     carryforwards. Valuation allowances are provided to the extent, if any,
     that it is more likely than not that deferred income tax assets will not be
     realized. A deferred tax asset or liability is, according to the
     classification of its related asset or liability, classified as current or
     non-current. However, if a deferred 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,
     marketing expenses for international branding, 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.

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

     Foreign Currency Transactions

     Foreign currency transactions are recorded in New Taiwan dollars at the
     current rate of exchange in effect when the transaction occurs. Exchange
     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 operations.

     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 a liability. Any resulting gain or loss upon settlement is
     charged to income in the period of settlement.

     The Company enters into interest rate swap transactions to manage exposures
     to 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.

                                      -10-



     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
     charged to income in the period of settlement.

     Reclassification

     Certain accounts in the financial statements as of and for the nine months
     ended September 30, 2002 have been reclassified to conform to the financial
     statements as of and for the nine months ended September 30, 2003.

3.   NEW ACCOUNTING PRONOUNCEMENTS

     In accordance with the 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 its
     subsidiaries from 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$1,914,700 thousand as of September 30, 2002, and the decrease in net
     income for the nine months ended September 30, 2002 by NT$43,036 thousand.

15.  SHAREHOLDERS' EQUITY

     Capital, Capital Surplus and Retained Earnings

     The Company has issued a total of 485,898 thousand ADSs which were traded
     on the NYSE as of September 30, 2003. The total number of common shares
     represented by all issued ADSs is 2,429,491 thousand shares (one ADS
     represents five common shares).

     On October 8, 2003, the Board of Director approved the Company's
     sponsorship of the offering by certain existing shareholders of up to
     500,000 thousand common shares in the form of ADSs. As of October 16, 2003,
     the offering was not effective as of SFC's approval.

     Capital surplus can only be used to offset a deficit under the ROC Company
     Law. However, the components of capital surplus generated from 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 stock as stock
     dividends.

     The Company's Articles of Incorporation provide that the following shall be
     appropriated from annual earnings if in excess of any cumulative deficit:

     a.  10% legal reserve; until the accumulated legal reserve has equaled the
         total paid-in capital of the Company;

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

                                      -18-



     c.  Remuneration to directors and supervisors and bonus to employees equals
         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 at a 3.5% annual rate, based
         on the period which the preferred shares have been outstanding.
         Following the redemption of all of its issued and outstanding preferred
         shares in May 2003, the Company amended its Articles of Incorporation
         on June 3, 2003, to remove the provision for issuance of any future
         dividends to preferred shareholders as of that date;

     e.  The appropriation of any remaining balance shall be approved by the
         shareholders.

     Dividends are distributed in shares of common stock or a combination of
     cash and common stock. Since the Company is in a capital-intensive industry
     and is currently in the growth stage of its operation, distributions of
     profits is made preferably in the form of stock dividend. The total of cash
     dividends paid in any given year may not exceed 50% of total dividends
     distributed in that year.

     Any appropriations of net income are recorded in the financial statement in
     the year of shareholder approval.

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

     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), other than the
     deficit, shall be made from unappropriated retained earnings pursuant to
     existing regulations promulgated by the SFC. The special reserve is allowed
     to be appropriated when the debit balance of such accounts is reversed.

     The appropriations of the earnings of 2002 and 2001 were approved in the
     shareholders' meeting on June 3, 2003 and May 7, 2002, respectively. The
     appropriations and dividend per share are as follows:

     The above appropriation of the earnings in fiscal year 2002 and 2001 is
     consistent with the resolution of the meetings of board of directors on
     March 4, 2003 and March 26, 2002, respectively. If the above employee bonus
     and remuneration to directors and supervisors were paid in cash and charged
     against income for 2002 and 2001, the basic earnings per share 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.

     Under the Integrated Income Tax System that became effective on January 1,
     1998, ROC resident shareholders are allowed a tax credit for their
     proportionate share of the income tax paid by the Company on earnings
     generated as of January 1, 1998. An imputation credit account is maintained
     by the Company for such income tax and the tax credit allocated to each
     shareholder.

     Employee Stock Option Plans

     On June 25, 2002, the SFC approved the Company's Employee Stock Option Plan
     (the Plan). The Plan provides qualified employees with 100,000 thousand
     units of option rights with each unit representing one common share of
     stock. The option rights are valid for ten years and exercisable at certain
     percentages subsequent to the second anniversary of issuance. Under the
     terms of the Plan, stock options are granted at an exercise price equal to
     the closing price of the Company's common shares listed on the TSE on the
     date of grant. Under the Plan, there were 50,378 thousand option rights
     that had never been granted, or had been granted but cancelled. These
     un-granted or cancelled option rights expired on September 30, 2003.

     Information  as of September  30, 2003 with respect to stock option  rights
     activities under the Plan is as follows:

     The aforementioned number of outstanding option rights and exercise prices
     have been adjusted, taken stock dividends into consideration, in accordance
     with the Plan.

     On September 2, 2003, the Board of Directors approved the 2003 employee
     stock option plan (the 2003 Plan). The maximum number of shares authorized
     to be granted is 120,000 thousand option rights. As of October 16, 2003,
     the 2003 Plan is in the process of SFC's approval.

     Preferred Stock

     The Company issued 1,300,000 thousand shares of unlisted Series
     A--preferred stock to certain investors on November 29, 2000. All of the
     preferred stock was redeemed at par value and retired on May 29, 2003.
     Under the Company's Articles of Incorporation, as amended on June 3, 2003,
     the Company is no longer authorized to issue preferred stock.

     The following are the rights of the preferred shareholders and the related
     terms and conditions prior to redemption:

     Preferred shareholders

     a.  are entitled to receive cumulative cash dividends at an annual rate of
         3.5%.

     b.  are not entitled to receive any common stock dividends (whether
         declared out of unappropriated earnings or capital surplus).

                                      -20-



     c.  have priority over the holders of common shares to the assets of the
         Company available for distribution to shareholders upon liquidation or
         dissolution; however, the pre-emptive rights to the assets shall not
         exceed the issue value of the shares.

     d.  have voting rights similar to that of the holders of common shares.

     e.  have no right to convert their shares into common shares. The preferred
         shares are to be redeemed within thirty months from their issuance. The
         preferred shareholders have the aforementioned rights and the Company's
         related  obligations  remain  the same until the  preferred  shares are
         redeemed by the Company.

     The potential common shares issuable under the employee stock option plan
     (see Note 15) are included in the denominator of the diluted EPS
     computation by using the treasury stock method under the SFAS No. 24,
     "Earnings Per Share", but such shares resulted in a non-dilutive per share
     amount for the nine months ended September 30, 2002. The average number of
     shares outstanding for the EPS calculation has been adjusted retroactively
     for issuance of stock dividends and stock bonuses. The retroactive
     adjustment caused the basic EPS before income tax and after income tax for
     the nine months ended September 30, 2002 to decrease from NT$1.28 to
     NT$1.17 and NT$1.01 to NT$0.93, respectively.

     Except for WaferTech and TSMC--North America, sales to related parties are
     based on normal selling prices and collection terms. The payables to
     WaferTech represent the purchase of finished goods. The purchase prices of
     finished goods were determined in accordance with the related contractual
     agreements. The selling prices to TSMC--North America are approximately 99%
     of the comparable selling prices to third parties and the payment terms are
     thirty days from the date of invoice, which is not significantly different
     from payment terms with third parties.

     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) with respect to
          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 fees
          to be paid after reduction 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 September 30, 2003, the
          Company has a total of US$24,929 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 allowed the Company to invest in 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 shall remain in force for ten years and may be
          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 Development), TSMC--North America and

                                      -25-



     h.   Under a Technology Transfer Agreement (TTA) with National
          Semiconductor Corporation (National) entered into on June 27, 2000,
          the Company 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 September 30, 2003, the refundable deposit was NT$260,992
          thousand.

     j.   Starting from 2001, the Company entered into several license
          arrangements for certain semiconductor patents. The terms of the
          contracts range from five to ten years with payments to be paid in the
          form of royalties over the term of the related contracts. The Company
          has recorded the related amounts as a liability and deferred charges
          which is amortized and charged to cost of sales on a straight-line
          basis over the estimated life of the technology or the term of the
          contract, whichever is shorter.

     k.   In November 2002, the Company entered into an Amended and Restated
          Joint Technology Cooperation Agreement with Philips, Motorola, Inc.
          and STMicroelectronics to jointly develop 90-nanometer to 65-nanometer
          advanced CMOS Logic and e-DRAM technologies. The Company also agreed
          to align 0.12 micron CMOS Logic technology to enhance its foundry
          business opportunities. The Company will contribute process
          technologies and share a portion of the costs associated with this
          joint development project.

     l.   Amounts available under unused letter of credits as of September 30,
          2003 were NT$6,480 thousand, EUR36 thousand and Singapore dollar $85
          thousand.

                                      -27-



               c)   Option contracts

                    The Company entered into foreign currency option contracts
                    to manage exchange rate fluctuations arising from its
                    anticipated US dollar cash receipts on export sales or its
                    Yen currency obligations for purchases of machinery and
                    equipment.

                    contracts.

                         values at 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.

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

                         As of September 30, 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
---------------               --------------------   ------------------
                                  (In Thousand)        (In Thousand)
Within one year               NT$       48,639,807   US$      1,472,647
                              EUR           38,000

                          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 rates
                          of forward foreign exchange contracts and option
                          contracts are fixed. Therefore, there is no material
                          fund raising risk and cash flow risk.

          2)   Fair value of financial instruments:

               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 asset value or book
                    value of investment.

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

               d)   The fair value of bonds payable is the quoted market value.
                    Fair value of other long-term payable is approximate to its
                    carrying value.

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

               The fair values of some financial and 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. The Company entered into an investment related
               agreement with Shanghai Songjiang District People's Government on
               June 8, 2003. On August 4, 2003, TSMC-Shanghai has been
               established and is 100% held by the Company. TSMC-Shanghai is
               engaged mainly in the manufacturing and selling of integrated
               circuits. The Company invested US$56,000 thousand on October 8,
               2003.
