EXCHANGE OFFER SUMMARY

The following is a summary of the terms of the exchange offer. The summary does not contain all the information that may be important to you. You should read the entire exchange offer prospectus before deciding to tender your GDSs to the exchange agent.

PURPOSE OF THE EXCHANGE OFFER

The purpose of the exchange offer is to provide holders of our GDSs sold under Rule 144A with freely transferable securities that we expect to be more widely held and actively traded, and to eliminate our restricted global depositary receipt facilities.

THE EXCHANGE OFFER

The Exchange Offer |  | The exchange of each outstanding GDSs, each representing five of our common shares, for one ADS representing five of our common shares.
American Depositary Shares |  | The ADSs are issuable pursuant to an amended and restated deposit agreement, dated as of September , 2000, among us, Citibank, N.A., as depositary, and the holders and beneficial owners from time to time of the ADSs.
|  | The ADSs offered by this prospectus are identical in all material respects to the GDSs, issued and sold pursuant to the GDS offering described below, except that the ADSs have been registered under the Securities Act of 1933 and approved for listing on the New York Stock Exchange, under the trading symbol “ASX”.
Global Depositary Shares |  | The GDSs were initially issued and sold in a combined Regulation S and Rule 144A offering on July 13, 1995 consisting of (1) an offering of GDSs outside the United States under Regulation S under the Securities Act and (2) an offering of GDSs in the United States to qualified institutional buyers under Rule 144A of the Securities Act. Some of our affiliates offered and sold an additional 10,489,902 GDSs in December 1999.
Exchange Agent |  | Citibank, N.A.
Information Agent |  | D.F. King.
Resale |  | The staff of the Division of Corporation Finance at the Securities and Exchange Commission has issued interpretive letters to third parties permitting resales of ADSs received in exchange for GDSs initially resold pursuant to Rule 144A, provided that the holder satisfies relevant conditions, including that the holder is not engaged in, and does not intend to engage in, a distribution of the ADSs to be received in that exchange. See “The Exchange Offer — Resales”.
Expiration Date |  | The exchange offer will expire at p.m., New York City time, on , unless we extend the exchange offer. See “The Exchange Offer — Expiration and Extension”.

S-1

##### Table of Contents

|  | We will publicly announce any extension through a release to the Dow Jones News Service.
Withdrawal Rights |  | You may withdraw your tenders of GDSs (1) at any time prior to the expiration date and (2) if not yet accepted for exchange, at any time after . See “The Exchange Offer — Withdrawal Rights”.
Conditions of the Exchange Offer |  | Closing of this exchange offer is conditional on the closing of our concurrent public offering of ADSs, but our obligation to complete the exchange offer does not require that a minimum number of GDSs be validly tendered. This exchange offer is subject to other conditions. For a discussion of the conditions of the exchange offer, see “The Exchange Offer — Conditions”.
Exchange Procedure |  | If you hold your GDSs in an account through a custodial agent, such as a broker, dealer, trust company, bank, custodian or other nominee, you will need to timely instruct your custodial agent to tender your GDSs as described below under the heading “The Exchange Offer — How to Tender”. After the expiration date, we will promptly accept the GDSs you have validly tendered in response to the exchange offer if all the terms and conditions of the exchange offer have been satisfied or waived. The ADSs will be delivered to you promptly after the expiration date by book-entry delivery to the account of your broker, dealer, trust company, bank custodian or other nominee through the facilities of The Depository Trust Company, or DTC.
|  | Although we do not currently intend to do so, if we modify the terms of the exchange offer before the expiration date, those modified terms will be made available to all holders of the GDSs, whether or not your GDSs have been tendered before that modification. We will extend the exchange offer, if necessary, to allow holders of the GDSs adequate time to consider any modification. See “The Exchange Offer — Acceptance of Tenders”.
Income Tax Considerations |  | The exchange offer will not be a taxable exchange for U.S. federal and Republic of China income tax purposes. See “Income Tax Considerations”.
Consequences of Failure to Exchange |  | Promptly following completion of the exchange offer, we intend to terminate the initial deposit agreement according to its terms. Termination will reduce the liquidity of the untendered GDSs.
Broker-Dealers |  | Each broker-dealer receiving ADSs for its own account under the exchange offer must acknowledge that it will deliver a prospectus in connection with any resale of such ADSs. By acknowledging and by delivering a prospectus, a broker-dealer will not be deemed to admit that it is an

| “underwriter” within the meaning of the Securities Act. This exchange offer prospectus, as it may be amended or supplemented from time to time, may be used by a broker-dealer in connection with resales of ADSs received in exchange for GDSs where such GDSs were acquired by such broker-dealer as a result of market-making activities or other trading activities. We have agreed that, for a period of 30 days after the expiration date, we will make this exchange offer prospectus available to any such broker-dealer for use in connection with such resale. See “Plan of Distribution”.

PURPOSE OF THE EXCHANGE OFFER

Our purpose in making the exchange offer is to provide holders of our GDSs with freely transferable securities that we expect to be more widely held and actively traded and to eliminate our restricted global depositary receipt facilities. The exchange offer is, for U.S. federal and Republic of China income tax purposes, a tax-free exchange of GDSs for ADSs that have been approved for listing on the New York Stock Exchange.

THE EXCHANGE OFFER

Terms of the Offer

We are offering, upon the terms and conditions set forth in this exchange offer prospectus, to exchange one ADS for each outstanding GDS. On September , 2000 there were approximately GDSs outstanding. Closing of this exchange offer is conditional on the closing of our concurrent public offering of ADSs, but the exchange offer is not conditioned upon the valid tender of any minimum number of GDSs. Holders of GDSs who are our affiliates may not participate in the exchange offer.

The exchange offer will expire at p.m., New York City time, on , unless we extend the exchange offer in our sole discretion. See “— Expiration and Extension”.

Holders of GDSs who wish to exchange their GDSs for ADSs and who validly tender their GDSs to the exchange agent according to the book-entry transfer procedures described below will receive their ADSs by book-entry delivery to the accounts of the participant in DTC who tendered GDSs in the exchange offer. See “— How to Tender”.

Subject to the terms and conditions of the exchange offer, validly tendered GDSs will be accepted promptly after the expiration date. Subject to the applicable rules of the SEC, we reserve the right to delay acceptance of tendered GDSs, or to terminate the exchange offer, upon the occurrence of any of the conditions set forth below under the caption “— Conditions”.

In addition, we reserve the right to waive any condition or otherwise amend the exchange offer in any respect. If any amendment or waiver constitutes a material change in the information previously disclosed to you, we will, in accordance with the applicable rules of the SEC, disseminate promptly disclosure of such change in a manner reasonably calculated to inform you of such change and, if necessary, we will extend the exchange offer to permit an adequate time for you to consider the additional information.

Certain Effects of the Exchange Offer

Because the exchange offer is for any and all GDSs, the number of GDSs accepted for tender in the exchange offer will reduce the number of outstanding GDSs. As a result, the liquidity of any remaining GDSs may be substantially reduced. Moreover, the intended termination of the initial deposit agreement described under the caption “Important Notice to Holders and Beneficial Owners of GDSs” on page S-10 of this exchange offer prospectus will eliminate the trading market for the remaining GDSs. The holder of any GDSs that remain outstanding after the expiration of the exchange offer will have the option, prior to the termination of the initial deposit agreement, and subject to the provisions there:

| • | to sell its GDSs in an offshore transaction in accordance with Regulation S or to a person it reasonably believes is a qualified institutional buyer in a transaction meeting the requirements of Rule 144A;
| • | to sell the common shares underlying such GDSs in a transaction on the Taiwan Stock Exchange; or

S-4

##### Table of Contents

| • | to withdraw the common shares underlying such GDSs, in each case subject to transaction and other costs as set forth in the initial deposit agreement and to applicable resale restrictions under the Securities Act.

Upon termination of the initial deposit agreement, such holder will be entitled to receive the common shares underlying such GDSs, provided, that at any time after the expiration of six months from the date of such termination, the depositary under the initial deposit agreement may sell the deposited common shares and hold the net proceeds of any such sale, together with any cash then held by it under the initial deposit agreement, without liability for interest, for the pro rata benefit of the GDS holders that have not surrendered such GDSs.

Expiration and Extension

The exchange offer will expire at p.m., New York City time, on , unless extended by us. During any extension of the exchange offer, all GDSs previously tendered pursuant to the exchange offer will remain subject to the exchange offer (and to the withdrawal rights specified here). The exchange offer may be extended by notice from us to the exchange agent on or prior to the scheduled expiration date. Public announcement of any extension of the exchange offer will be made by us no later than a.m., New York City time on the next business day after the scheduled expiration date. Unless otherwise required by law or regulation, we will not have any obligation to communicate such public announcement other than by making a release to the Dow Jones News Service.

Conditions

Closing of this exchange offer is conditional on the closing of our concurrent public offering of ADSs, but this exchange offer is not conditioned upon the valid tender of any minimum number of GDSs. Notwithstanding any other provisions or any extension of the exchange offer, we (1) will not be required to issue ADSs for your validly tendered but not yet accepted GDSs, (2) may terminate the exchange offer and (3) subject to compliance with the applicable rules of the SEC, delay the acceptance of the tendered GDSs if any material change occurs on or prior to the expiration date that is likely to affect the exchange offer. If we decide to terminate the exchange offer, we will provide notice to the exchange agent and provide timely public announcement by making a release to the Dow Jones News Service, unless otherwise required by applicable law or regulation. Examples of material change that is likely to affect the exchange offer includes, but is not limited to, the following:

| • | any action or proceeding before any court or governmental agency challenging the exchange offer or otherwise directly or indirectly relating to the exchange offer is instituted or threatened;
| • | any development in any pending action or proceeding which, in our reasonable judgment, would or might (1) prohibit, restrict or delay consummation of the exchange offer or (2) impair the contemplated benefits of the exchange offer;
| • | any proposed or enacted statute, rule or regulation or any action by any governmental authority which, in our reasonable judgment, would or might (1) prohibit, restrict or delay consummation of the exchange offer or (2) impair the contemplated benefits of the exchange offer;
| • | any change, or development involving a prospective change, which has had or may have a material adverse effect on the exchange offer; or
| • | there exists, in our reasonable judgment, any actual or threatened legal impediment to the consummation of the transactions contemplated by the exchange offer, including a default or prospective default in any of our agreements, instruments or obligations.

S-5

##### Table of Contents

We expressly reserve the right to terminate the exchange offer and not accept for exchange any GDSs upon the occurrence of any material change that is likely to affect the exchange offer, including any of the conditions above. In addition, we may amend the exchange offer at any time prior to the expiration date if any material change has occurred. Moreover, regardless of whether any material change has occurred, we reserve the right to amend the exchange offer in any manner prior to the expiration date, although we have no current intention to do so.

The above conditions are for our sole benefit and may be waived by us, in whole or in part, in our reasonable discretion, subject to compliance with the applicable rules of the SEC. Any determination made by us concerning an event, development or circumstance described or referred to above will be final and binding on all parties to the exchange offer.

How to Tender

Holders of GDSs wishing to tender their GDSs in exchange for ADSs will need to timely instruct their broker, dealer, bank, trust company, custodian, nominee or agent to arrange for the participant in DTC holding the GDSs through its DTC account to (1) deliver the GDSs by means of book-entry transfer into the exchange agent’s DTC account and (2) transmit an agent’s message to the exchange agent through the facilities of DTC, specifying that the participant has received and agrees to be bound by the terms and conditions set forth in this exchange offer prospectus, in each case prior to the expiration of this exchange offer.

By taking these actions, you and your agent will be deemed to have agreed (1) to the terms and conditions of the exchange offer set forth in this exchange offer prospectus and (2) that we and the exchange agent may enforce that agreement against you and your agent.

Any whole number of GDSs may be tendered. Tendering holders may tender less than all of the GDSs they hold provided they appropriately indicate such fact. Tenders of fractional GDSs will not be accepted.

The method of delivery of GDSs and all other documents and instructions, including the notification of tender through DTC, is at the risk of the holder.

We reserve full discretion to determine whether the instructions, electronic messages and other documentation accompanying tenders of GDSs are complete, and generally to determine all questions as to tenders, including (1) the date of receipt of a tender, (2) the propriety of any instruction, (3) electronic messages or execution of any document, and (4) other questions as to the validity, form, eligibility or acceptability of any tender. We reserve the right to reject any tender not in proper form or otherwise not valid or the acceptance for exchange of which may, in the opinion of our counsel, be unlawful or to waive any irregularities or conditions. Our interpretation of the terms and conditions of the exchange offer will be final. We will not be obligated to give notice of any defects or irregularities in tenders and will not incur any liability for failure to give any such notice. The exchange agent may, but will not be obligated to, give notice of any irregularities or defects in tenders, and will not incur any liability for any failure to give any such notice. GDSs will not be deemed to have been duly or validly tendered unless and until all defects and irregularities have been cured or waived. All improperly tendered GDSs will be returned, unless irregularities and defects are timely cured or waived, by credit to the account maintained within DTC by the participant DTC which delivered such GDSs, promptly after the expiration date.

Guaranteed Delivery Procedures

If a holder desires to tender GDSs under the exchange offer and such holder’s GDSs are not immediately available or time will not permit a valid tender to the exchange agent prior to the expiration date, that holder may effect a valid tender by means of a notice of guaranteed delivery

S-6

##### Table of Contents

transmitted to the exchange agent and by means of an agent’s message upon the terms set forth above.

Tender by means of a notice of guaranteed delivery will require the holder of GDSs to validly tender the GDSs to the exchange agent within three New York Stock Exchange trading days in the manner described above. See “— How to Tender”. Failure to do so will invalidate the tender made by means of a notice of guaranteed delivery.

A tender will be deemed to have been validly received by the exchange agent as of the date when the exchange agent receives confirmation of receipt by book-entry transfer of GDSs and an applicable agent’s message into the exchange agent’s account at DTC.

Resales

Based upon existing interpretations of the staff of the SEC set forth in several no-action letters issued to third parties, ADSs issued pursuant to the exchange offer in exchange for the GDSs may be offered for resale, resold and otherwise transferred by the holders, without complying with the registration and prospectus delivery provisions of the Securities Act, provided that such holder is:

| • | not our “affiliate” or “promoter”, as such terms are defined in Rule 405 under the Securities Act. An “affiliate” of a specified person is defined under the Securities Act to mean a person that directly or indirectly controls or is controlled by, or is under common control with, the specified person. A “promoter” is defined under the Securities Act as (1) any person, directly or indirectly, initiates in founding and organizing the business of an issuer or (2) any person who, in connection with the founding and organizing of the business of the issuer, directly or indirectly, receives in consideration of services or property, or both services and property, 10% or more of any class of securities of the issuer or 10% or more of the proceeds from the sale of any class of those securities;
| • | not participating, and has no arrangement or understanding with any person to participate, in a distribution of the ADSs to be received in the exchange offer;
| • | not a broker-dealer that purchased the GDSs in the GDS offering for resale pursuant to Rule 144A or another available exemption under the Securities Act; and
| • | acquiring the ADSs in the ordinary course of such holder’s business.

If any holder of GDSs does not satisfy any of the foregoing conditions, such holder (1) will not be entitled to rely on the foregoing staff interpretation and (2) must comply with the registration and prospectus delivery requirements of the Securities Act in connection with any resale transaction, including the delivery of a prospectus that contains information required by Item 507 of Regulation S-K with respect to selling shareholders. Such holders wishing to accept the exchange offer must represent to us that such conditions have been met.

Each broker-dealer that receives ADSs for its own account pursuant to the exchange offer must acknowledge that it will deliver a prospectus in connection with any resale of such ADSs. By so acknowledging and by delivering a prospectus, a broker-dealer will not be deemed to admit that it is an “underwriter” within the meaning of the Securities Act. This exchange offer prospectus, as it may be amended or supplemented from time to time, may be used by a broker-dealer in connection with resales of ADSs received in exchange for GDSs where such GDSs were acquired by such broker-dealer as a result of market-making activities or other trading activities. We have agreed that, for a period of 30 days after the expiration date, we will make this exchange offer prospectus available to any such broker-dealer for use in connection with such resale. See “Plan of Distribution”.

We will also make each person participating in the exchange offer aware that any broker-dealer who holds GDSs acquired for its own account as a result of market-making activities or

S-7

##### Table of Contents

other trading activities may participate in the exchange offer so long as the broker-dealer has not entered into any arrangement or understanding with us or an affiliate of ours to distribute the ADSs. We will also make each person participating in the exchange offer aware that any broker-dealer who holds GDSs acquired for its own account as a result of market-making activities or other trading activities and who receives ADSs in exchange for such GDSs in the exchange offer may be a statutory underwriter and must deliver a prospectus meeting the requirements of the Securities Act in connection with any resale of the ADSs.

We believe that none of our affiliates, as defined in Rule 405 under the Securities Act, owns GDSs that are the subject of this exchange offer.

If any holder of GDSs does not satisfy each of the foregoing conditions, such holder will not be entitled to rely on the foregoing interpretations of the SEC.

Withdrawal Rights

You may withdraw your tendered GDSs (1) at any time prior to the expiration date and (2) if not yet accepted for exchange after . If you tendered your GDSs through an agent and wish to withdraw your tender of your GDSs, you will need to make arrangements with your agent. Your ability to withdraw the tender of your GDSs will depend upon the terms of the arrangements you have with your agent and, if your agent is not a DTC participant tendering those GDSs, the arrangements between your agent and the DTC participant tendering those GDSs, including any arrangements involving intermediaries between your agent and the DTC participant.

We will determine all questions as to the validity, including, without limitation, questions with regard to timeliness, of notices of withdrawal in respect of GDSs that have been delivered to the applicable exchange agent, and that determination will be final and binding on the parties. You and your agent bear the risks arising in connection with the procedures for withdrawal, and we disclaim any liabilities or obligations in connection with these risks.

Acceptance of Tenders

Subject to the terms and conditions of the exchange offer, including the reservation of some of our rights, we will accept GDSs tendered and not withdrawn promptly after the applicable expiration date. Subject to such terms and conditions, beneficial interests in ADSs to be issued in exchange for properly tendered GDSs will be recorded in records maintained by (1) DTC or its nominee or (2) institutions that have accounts at DTC. Acceptance of tendered GDSs will be effected upon the occurrence of any of the conditions set forth above under the caption “— Conditions”.

Although we do not currently intend to do so, if we modify the terms of the exchange offer, we will make those modified terms available to you, whether or not you had tendered prior to that modification. We will disclose any material modification in accordance with the applicable rules of the SEC and, if required, we will extend the exchange offer to permit you to have adequate time to consider that modification.

Tendering your GDSs pursuant to any one of the procedures set forth in “— How to Tender” will constitute an agreement between the tendering holder and us upon the terms and subject to the conditions of the exchange offer. Our acceptance for exchange of GDSs tendered pursuant to the exchange offer will constitute a binding agreement between the tendering holder and us upon the terms and subject to the conditions of the exchange offer.

Solicitation of Tenders; Expenses

Except as described below under “Exchange Agent” and “Information Agent”, we have not retained any agent in connection with the exchange offer and will not make any payments to

S-8

##### Table of Contents

brokers, dealers or other persons for soliciting or recommending acceptances of the exchange offer. We will, however, reimburse the exchange agent and information agent for its attorney’s fees and disbursements and certain reasonable out-of-pocket expenses in connection with this exchange offer. We will also pay brokerage houses and other custodians, nominees and fiduciaries the reasonable out-of-pocket expenses incurred by them in forwarding copies of this exchange offer prospectus and related documents to the beneficial owners of the GDSs or underlying common shares and in handling or forwarding tenders for their customers.

PLAN OF DISTRIBUTION

Each broker-dealer that receives ADSs for its own account pursuant to the exchange offer must acknowledge that it will deliver a prospectus in connection with any resale of such ADSs. This exchange offer prospectus, as it may be amended or supplemented from time to time, may be used by a broker-dealer in connection with resales of ADSs received in exchange for GDSs where such GDSs were acquired as a result of market-making activities or other trading activities. Each broker-dealer participating in the exchange offer will represent that the GDSs being exchanged for ADSs were acquired as a result of market-making or other trading activities. We have agreed that for a period of 30 days after the expiration date, we will make this exchange offer prospectus, as amended or supplemented, available to any broker-dealer for use in connection with any such resale.

We will not receive any proceeds from any sale of ADSs by broker-dealers. ADSs received by broker-dealers for their own accounts pursuant to the exchange offer may be sold from time to time in one or more transactions on the New York Stock Exchange, in negotiated transactions, through the writing of options on the ADSs or a combination of such methods of resale, at market prices prevailing at the time of resale, at prices related to such prevailing market prices or at negotiated prices. Any such resale may be made directly to purchasers or to or through brokers or dealers who may receive compensation in the form of commissions or concessions from any such broker-dealers and/or the purchasers or any such ADSs. Any broker-dealer that resells ADSs that were received by it for its own account pursuant to the exchange offer and any broker or dealer that participates in a distribution of such ADSs may be deemed to be an “underwriter” within the meaning of the Securities Act and any profit on any such resale of ADSs and any commissions or concessions received by any such persons may be deemed to be underwriting compensation under the Securities Act. By acknowledging that it will deliver and by delivering a prospectus, a broker-dealer will not be deemed to admit that it is an “underwriter” within the meaning of the Securities Act.

For a period of 30 days after the expiration date, we will promptly send additional copies of this exchange offer prospectus and any amendment or supplement to this exchange offer prospectus to any broker-dealer that requests such documents.

INCOME TAX CONSIDERATIONS

The following discussion is the opinion of Davis Polk & Wardwell. Under U.S. federal income tax law, a holder of GDSs will not recognize gain or loss upon an exchange of such GDSs for ADSs pursuant to the exchange offer. A holder’s tax basis in the ADSs received pursuant to the exchange offer will be the same as such holder’s basis in the exchanged GDSs and a holder’s holding period for ADSs received pursuant to the exchange offer will include such holder’s holding period for the GDSs. For a discussion of the material U.S. federal income tax consequences of the ownership and disposition of common shares or ADSs, see the section under the heading “Taxation — United States Federal Income Taxation” of the attached prospectus set forth in Annex I.

##### Table of Contents

The following discussion is the opinion of Lee and Li. Under the Republic of China income tax law, the exchange of GDSs for ADSs pursuant to the exchange offer will not be a taxable exchange. For a discussion of the material tax consequences of the ownership and disposition of common shares or ADSs under the laws of the Republic of China, see the section under the heading “Taxation — ROC Taxation” of the attached prospectus set forth in Annex I.

Each exchanging holder should consult with its individual tax advisor as to any foreign, state and local tax consequences of the exchange offer as well as to the effect of its particular facts and circumstances on the matters discussed here.

LEGAL MATTERS

The validity of the common shares represented by the ADSs will be passed upon for us by Lee and Li, our ROC counsel.

IMPORTANT NOTICE TO HOLDERS AND BENEFICIAL OWNERS OF GDSs

Your GDSs have been issued under the initial deposit agreement, dated as of July 13, 1995, as amended as of November 30, 1998, and as supplemented as of December 14, 1999, among us, Citibank, N.A., as depositary, and the holders and beneficial owners from time to time of the GDSs sold under Rule 144A and of the GDSs sold pursuant to Regulation S. The initial deposit agreement provides that whenever so directed by us, the depositary will terminate the agreement by providing notice of such termination to holders of the GDSs at least 30 days prior to the date of termination fixed in such notice.

We have directed the depositary to terminate the initial deposit agreement in accordance with its terms. We provide you in this prospectus with notice of such termination. As of the date of this exchange offer prospectus, the depositary will no longer accept common shares for deposit.

If any GDSs remain outstanding after the date of termination of the initial deposit agreement, the depositary:

| • | will discontinue the registration of transfers of GDSs;
| • | will suspend the distribution of dividends to holders of GDSs; and
| • | will not file any further notices or perform any further acts under the initial deposit agreement;

except:

| • | collect dividends and other distributions made upon the deposited common shares underlying the GDSs;
| • | sell any rights as provided in the initial deposit agreement; and
| • | deliver, in exchange for any GDSs surrendered to the depositary, (1) any dividends or other distributions received and (2) the net proceeds from the sale of any rights or other property.

Under the terms of the initial deposit agreement, holders of GDSs remaining outstanding after termination will be required to pay to the depositary $5.00 per 100 GDSs surrendered before taking the deposited common shares underlying the GDSs or the proceeds of the sale of those common shares. The depositary has agreed, solely in connection with tenders of GDSs made under this exchange offer, to waive the GDSs surrender fee that would otherwise be payable by holders of GDSs under the initial deposit agreement. At any time after the expiration of six months from the date of termination, the depositary may sell the deposited common

S-10

shares and hold the net proceeds of any sale, together with any cash then held, without liability for interest, for the pro rata benefit of the GDS holders who have not previously surrendered their GDSs.

Because the GDSs held by our affiliates are not eligible to be exchanged, following the conclusion of the exchange offer, we intend to cause our affiliates holding the restricted GDSs to surrender the GDSs for restricted ADSs. The restricted ADSs will be issued in certificated form, appropriately legended, in accordance with the terms of the deposit agreement.

PROSPECTUS SUMMARY

This summary highlights information found in greater detail elsewhere in this prospectus. In addition to this summary, we urge you to read the entire prospectus carefully, especially the discussion of the risks of investing in our ADSs under “Risk Factors”, before deciding to buy our ADSs.

Business

We believe we are one of the world’s largest independent providers of semiconductor packaging services and, together with our subsidiary ASE Test Limited, one of the world’s largest independent providers of semiconductor testing services, including front-end engineering testing, wafer probing and final testing services. Semiconductor packaging is the processing of bare semiconductors into finished semiconductors with enhanced electrical and thermal characteristics, and semiconductor testing is the use of sophisticated equipment and customized software programs to electrically test specified attributes of semiconductors. We offer packaging and testing services on both stand-alone and turnkey bases. Turnkey services consist of the integrated packaging, testing and direct shipment of semiconductors to end users designated by our customers.

We believe that we are better positioned than our competitors to meet the requirements of semiconductor companies worldwide for outsourced packaging and testing services across a wide range of end use applications because of:

| • | our broad range of advanced semiconductor packaging and testing services;
| • | our expertise in product and process technology for the manufacture of increasingly advanced semiconductor packages;
| • | our expertise in interconnect materials and assembly of electronics boards;
| • | our financial position which enables us to make significant investments for future growth through both the expansion of existing capacity and the acquisition of new businesses, technologies and operations;
| • | our experience in integrating acquired operations and using the acquired operations to provide services to their former owners;
| • | our strategic geographic locations with experienced teams in key centers for outsourced semiconductor manufacturing; and
| • | our ability to expand the traditional scope of turnkey services to offer total semiconductor manufacturing services to our customers through our strategic alliance with Taiwan Semiconductor Manufacturing Company Limited, the world’s largest dedicated semiconductor foundry.

We plan to continue to expand our business and operations through both internal growth and acquisitions in order to enhance our technological, processing and materials capabilities, broaden our geographic coverage and increase our production capacity, economies of scale and management resources. In 1999, in addition to the expansion of our existing facilities, we also acquired:

| • | the semiconductor packaging and testing facilities of Motorola, Inc. in Taiwan and Korea;
| • | a controlling 22.6% interest in Universal Scientific Industrial Co., Ltd., a leading contract provider of electronics board assembly services in Taiwan, which was subsequently increased to 23.3% following our purchase of additional shares in the open market in July and August of 2000; and

##### Table of Contents

| • | a 70% interest in ISE Labs, Inc., a front-end engineering testing service provider, which was subsequently increased to 75.3% following ASE Test’s purchase of $30 million of additional shares of ISE Labs in April 2000.

We have a global base of over 200 customers, including:

• Advanced Micro Devices, Inc.

• Altera Corporation

• ATI Technologies Inc.

• Cirrus Logic International Ltd.

• Conexant Systems, Inc.

• Delphi Automotive Systems Corp.

• DSP Group

• LSI Logic Corporation

• Motorola, Inc.

• Philips Electronics NV

• Qualcomm Incorporated

• ST Microelectronics Pte Ltd.

• VIA Technologies, Inc.

Strategy

Our objective is to provide leading-edge semiconductor packaging and testing solutions which set industry standards and facilitate the industry trend to outsource semiconductor manufacturing requirements. The principal elements of our strategy are to:

| • | expand strategically our production capacity and product expertise through both internal growth and acquisitions;
| • | enhance our technological, processing and materials capabilities;
| • | develop strategic alliances with providers of complementary manufacturing services;
| • | better serve our customers through our diversified geographic presence in key centers for outsourced semiconductor manufacturing, including Taiwan, Malaysia, Singapore, Korea and Silicon Valley in California; and
| • | achieve economies of scale from our expanded production capacity.

ROC share issuance procedures |  | Under Republic of China, or ROC, share issuance
| and temporary limitation on |  | procedures applicable to offerings of ADSs representing
| withdrawal of common shares |  | newly-issued shares of ROC companies, we will initially
| from the ADS facility |  | deliver to our ADS depositary one or more certificates of payment that represent the irrevocable right to receive the common shares of ASE Inc. that will be represented by the ADSs offered by this prospectus. Upon completion of all required ROC share issuance procedures, which typically takes no more than 60 days, we will deliver common shares of ASE Inc. to our ADS depositary in exchange for those certificates of payment. Until that exchange has been completed, the ADSs offered by this prospectus will represent interests in the certificates of payment held by our ADS depositary. During this period, except as described under “Description of Common Shares — Certificates of Payment” in this prospectus, holders of ADSs will be entitled to the same rights as if the depositary were holding the common shares that will be delivered by us in exchange for the certificates of payment. Except where the context otherwise requires, all references in this prospectus to the common shares represented by our ADSs assume that we have completed the exchange of common shares for certificates of payment, and during the period before completion of this exchange those references shall be deemed as references to the certificates of payment initially delivered to our ADS depositary.
|  | In addition, under ROC regulations applicable to offerings of ADSs, newly-issued common shares of ROC companies initially offered in ADS form may not be withdrawn from the ADS facility until three months following the initial delivery of the ADSs. Consequently, for a period of three months following the closing of this offering, owners of the ADSs offered by this prospectus will not be able to withdraw the underlying common shares from our ADS facility. Until the expiration of this three-month period, the ADSs offered by this prospectus are expected to trade on the NYSE under the temporary symbol “ASX Pr”. Although the common shares that will be represented by the ADSs, if any, purchased by the underwriters pursuant to the exercise of their over-allotment option will not be newly-issued common shares, those ADSs will not be distinguishable from the other ADSs being offered in this offering and consequently will be subject to the same restrictions on withdrawal of the underlying common shares for this three-month period. See “Description of American Depositary Receipts — Withdrawal of Common Shares Upon Cancellation of ADSs”.

RISK FACTORS

You should carefully consider the risks described below before making an investment decision. In particular, as we are a non-U.S. company, there are risks associated with investing in our ADSs that are not typical with investments in the shares of U.S. companies. Before making an investment decision, you should carefully consider all of the information contained in this prospectus, including the following risk factors.

Risks Relating to Our Business

Since we are dependent on the highly cyclical semiconductor industry and conditions in the markets for the end use applications of our products, our revenues and earnings may fluctuate significantly.

Our semiconductor packaging and testing business is affected by market conditions in the highly cyclical semiconductor industry. All of our customers operate in this industry, and variations in order levels from our customers and service fee rates may result in volatility in our revenues and earnings. From time to time, the semiconductor industry has experienced significant, and sometimes prolonged, downturns. Because our business is, and will continue to be, dependent on the requirements of semiconductor companies for independent packaging and testing services, any future downturn in the semiconductor industry would reduce demand for our services. For example, a worldwide slowdown in demand for semiconductor devices led to excess capacity and increased competition beginning in early 1998. As a result, price declines in 1998 accelerated more rapidly and adversely affected our operating results in 1998. With the upturn in the semiconductor industry in the second half of 1999 and the continued strong performance during the first half of 2000, prices for packaging and testing services improved. However, if the industry were to encounter another downturn, there may again be downward pressure on the average selling prices for our packaging and testing services. If we cannot reduce our costs to sufficiently offset any decline in average selling prices, our profitability will suffer.

Market conditions in the semiconductor industry depend to a large degree on conditions in the markets for the end use applications of the semiconductor products, such as personal computers, communications and consumer electronics. Any deterioration of conditions in the markets for the end use applications of the semiconductors we package and test would reduce demand for our services and, in turn, would likely have a material adverse effect on our financial condition and results of operations. In 1999 and the first half of 2000, approximately 78% and 73%, respectively, of our sales was attributable to the packaging and testing of semiconductors used in personal computer and communications applications. Both industries are subject to intense competition and significant shifts in demand which could put pricing pressure on the packaging and testing services provided by us and have a negative effect on our revenues and earnings.

A reversal or slowdown in the outsourcing trend for semiconductor packaging and testing services could adversely affect our growth prospects and profitability.

In recent years, semiconductor manufacturers that have their own in-house packaging and testing capabilities, known as integrated device manufacturers, have increasingly outsourced stages of the semiconductor production process, including packaging and testing, to independent companies to reduce costs and shorten production cycles. In addition, the availability of advanced independent semiconductor manufacturing services has also enabled the growth of so called “fabless” semiconductor companies that focus exclusively on design and marketing, and which outsource their manufacturing, packaging and testing requirements to independent companies. We cannot assure you that these integrated device manufacturers and fabless semiconductor companies will continue to outsource their packaging and testing requirements to

third parties like us. A reversal of, or a slowdown in, this outsourcing trend could result in reduced demand for our services and adversely affect our growth prospects and profitability.

If we are unable to compete favorably in the highly competitive semiconductor packaging and testing markets, our profits may decrease.

The semiconductor packaging and testing markets are very competitive. We face competition from a number of sources, including other independent semiconductor packaging and testing companies, especially those which offer turnkey packaging and testing services. We believe that the principal competitive factors in the markets for our products and services are:

| • | technological expertise;
| • | ability to work closely with customers at the product development stage;
| • | production yield;
| • | responsiveness and flexibility;
| • | cycle time;
| • | capacity;
| • | production time;
| • | range and quality of packaging types and testing platforms available; and
| • | price.

We face increasing competition from other packaging and testing companies in Asia. In particular, most of our customers obtain packaging or testing services from more than one source. Furthermore, some of our competitors may have access to more advanced technologies and greater financial and other resources than we do. Many of our competitors have shown a willingness to quickly and sharply reduce prices, as they did in 1998, in order to maintain capacity utilization in their facilities during periods of reduced demand. Although prices have since stabilized, any renewed erosion in the prices for our packaging and testing services could cause our profits to decrease and have a material adverse effect on our financial condition and results of operations.

Our profitability depends on our ability to respond to rapid technological changes in the semiconductor industry.

The semiconductor industry is characterized by rapid increases in the diversity and complexity of semiconductors. As a result, we expect that we will need to constantly offer more sophisticated packaging and testing technologies and processes in order to respond to competitive industry conditions and customer requirements. If we fail to develop, or obtain access to, advances in packaging or testing technologies or processes, we may become less competitive and less profitable. In addition, advances in technology typically lead to declining average prices for semiconductors packaged or tested with older technologies or processes. As a result, if we cannot reduce the costs associated with our services, the profitability on a given service, and our overall profitability, may decrease over time.

Our operating results are subject to significant fluctuations, which could negatively impact the market value of your investment.

Our operating results have varied significantly from period to period and may continue to vary in the future. Downward fluctuations in our operating results may result in decreases in the

10

##### Table of Contents

market price of our ADSs and common shares. Among the more important factors affecting our quarterly and annual operating results are the following:

| • | our ability to quickly adjust to unanticipated declines or shortfalls in demand and market prices for our packaging and testing services, due to our high percentage of fixed costs;
| • | timing of capital expenditures in anticipation of future orders;
| • | changes in prices of our packaging and testing services;
| • | volume of orders relative to our packaging and testing capacity;
| • | our ability to obtain adequate packaging and testing equipment on a timely basis; and
| • | changes in costs and availability of raw materials, equipment and labor.

Due to the factors listed above, it is possible that our future operating results or growth rates may be below the expectations of research analysts and investors. If so, the market price of our ADSs and common shares, and thus the market value of your investment, may fall.

Due to our high percentage of fixed costs, we will be unable to maintain our profitability at past levels if we are unable to achieve relatively high capacity utilization rates.

Our operations are characterized by relatively high fixed costs. We expect to continue to incur substantial depreciation and other expenses in connection with the acquisition of new packaging and testing equipment and new facilities. Our profitability depends in part not only on absolute pricing levels for our services, but also on utilization rates for our packaging and testing equipment, commonly referred to as “capacity utilization rates”. In particular, increases or decreases in our capacity utilization rates can have a significant effect on gross margins since the unit cost of packaging and testing services generally decreases as fixed costs are allocated over a larger number of units. In the first half of 1999, we experienced lower than anticipated capacity utilization rates in our operations due to lower than expected growth in demand, which led to reduced margins during that period. Although our capacity utilization rates have improved recently, we cannot assure you that we will be able to maintain or surpass our past profitability levels if we cannot consistently achieve or maintain relatively high capacity utilization rates.

If we are unable to manage our expansion effectively, our growth prospects may be limited and our future profitability may be affected.

We have significantly expanded our packaging and testing operations in recent years, and expect to continue to expand our operations in the future. In particular, we intend to expand our operations geographically, attract new customers and broaden our product range to include products packaged and tested for a variety of end use applications. In the past, we have expanded through both internal growth and the acquisition of new operations. Rapid expansion puts strain on our managerial, technical, financial, operational and other resources. As a result of our expansion, we have implemented and will continue to need to implement additional operational and financial controls and hire and train additional personnel. Any failure to manage our growth effectively could lead to inefficiencies and redundancies and result in reduced growth prospects and profitability.

We need to successfully integrate and manage our acquisitions to maintain profitability.

We intend to grow in part through the acquisition of semiconductor packaging and testing operations that complement our existing business. This strategy will involve reviewing and potentially reorganizing acquired business operations, corporate structures and systems and financial controls. The success of our acquisition strategy may be limited because of unforeseen expenses, difficulties, complications and delays encountered in connection with these acquisitions. We may not be able to acquire or manage profitably additional businesses or to

11

##### Table of Contents

integrate successfully any acquired businesses into our existing business without substantial costs, delays or other operational or financial difficulties. In addition, we may be required to incur additional debt or issue additional equity to pay for future acquisitions.

In 1999, we acquired the packaging and testing operations of ISE Labs, ASE Chung Li and ASE Korea, as well as a controlling 22.6% interest in Universal Scientific. We continue to evaluate acquisition opportunities and plan to make additional acquisitions in the future if suitable opportunities arise. These acquisitions may dilute our earnings per share as a result of the specific scope of the businesses or condition of the operations being acquired. In particular, these acquisitions may involve risks, including:

| • | integration and management of the operations;
| • | retention of select management personnel;
| • | integration of purchasing operations and information systems;
| • | coordination of sales and marketing efforts;
| • | cost of any pending or potential litigation against the acquired businesses prior to our acquisition;
| • | management of an increasingly larger and more geographically disparate business; and
| • | diversion of management’s attention from other ongoing business concerns.

We depend on select management personnel from acquired businesses for the continued operation of these businesses. If we are unable to retain these management personnel, we may have difficulty achieving profitability in our recently acquired businesses. Although some of these management personnel have entered into employment agreements with us, they may nevertheless leave before the expiration of these agreements. We are not insured against the loss of any of our personnel.

If we are unable to successfully integrate and manage our recent acquisitions, as well as any future acquisitions that we might pursue, our growth plans may not be met and our profitability may decline.

Because of the highly cyclical nature of our industry, our capital requirements are difficult to plan. If we cannot obtain additional capital when we need it, our growth prospects and future profitability may be adversely affected.

Our capital requirements are difficult to plan in our highly cyclical and rapidly changing industry. We will need capital to fund the expansion of our facilities as well as research and development activities in order to remain competitive. We believe that our current cash and cash equivalents, cash flow from operations and the proceeds from this offering will be sufficient to meet our anticipated needs at least through the end of 2000, including for working capital and capital expenditure requirements. However, future acquisitions or market or other developments may cause us to require additional funds. Our ability to obtain external financing in the future is subject to a variety of uncertainties, including:

| • | our future financial condition, results of operations and cash flows;
| • | general market conditions for financing activities by semiconductor companies; and
| • | economic, political and other conditions in Taiwan and elsewhere.

If we are unable to obtain funding in a timely manner or on acceptable terms, our growth prospects and future profitability may decline.

##### Table of Contents

We depend on select personnel and could be affected by the loss of their services.

We depend on the continued service of our executive officers and skilled technical and other personnel. Our business could suffer if we lose the services of any of these personnel and cannot adequately replace them. In particular, we will be required to increase substantially the number of these employees in connection with our expansion plans, and there is intense competition for their services in the semiconductor industry. We may not be able to either retain our present personnel or attract additional qualified personnel as and when needed. In addition, we may need to increase employee compensation levels in order to attract and retain our existing officers and employees and the additional personnel that we expect to require. A portion of the workforce at our facilities in Taiwan are foreign workers employed by us under work permits which are subject to government regulations on renewal and other terms. Consequently, our business could also suffer if the Taiwan regulations relating to the import of foreign workers were to become significantly more restrictive or if we are otherwise unable to attract or retain these workers at reasonable cost.

Criminal charges were brought in December 1998 by the district attorney for Taipei against Jason C.S. Chang, our Chairman, Richard H.P. Chang, our Vice Chairman and Chief Executive Officer, and Chang Yao Hung-ying, our director, and others. ASE Inc. is not a party to these proceedings and we do not expect that these charges will result in any liability to us. If convicted, they would have to resign from their respective positions in our company and in ASE Group companies. See “Business — Legal Proceedings”.

If we are unable to obtain additional packaging and testing equipment or facilities in a timely manner and at a reasonable cost, our competitiveness and future profitability may be adversely affected.

The semiconductor packaging and testing business is capital intensive and requires significant investment in expensive equipment manufactured by a limited number of suppliers. The market for semiconductor packaging and testing equipment is characterized, from time to time, by intense demand, limited supply and long delivery cycles. Our operations and expansion plans depend on our ability to obtain a significant amount of these equipment from a limited number of suppliers, including, in the case of testers, Credence Systems Corporation, Teradyne, Inc., Hewlett-Packard Asia Pacific Limited, Schlumberger Technologies, Advantest Corporation, Electroglas, Inc. and Megatest Corporation and, in the case of wire bonders, Kulicke & Soffa Industries Inc. and Shinkawa Limited. There is currently significant global demand for capital equipment, particularly testers, and the lead time for the delivery of capital equipment may be six months or more following the time when orders are placed. We have no binding supply agreements with any of our suppliers and acquire our packaging and testing equipment on a purchase order basis, which exposes us to changing market conditions and other substantial risks. For example, shortages of capital equipment could result in an increase in the price of equipment and longer delivery times. Semiconductor packaging and testing also requires us to operate sizeable facilities. We are currently constructing additional facilities in Malaysia and Taiwan to meet anticipated demand. See “Business — Facilities.” If we are unable to obtain equipment or facilities in a timely manner, we may be unable to fulfill our customers’ orders, which could negatively impact our growth prospects as well as financial condition and results of operations.

Fluctuations in exchange rates could result in foreign exchange losses.

Currently, the majority of our revenues from packaging and testing services are denominated in U.S. dollars and NT dollars. Our costs of revenues and operating expenses associated with packaging and testing services, on the other hand, are incurred in several currencies, including NT dollars, U.S. dollars, Malaysian ringgit, Korean won, Philippine pesos, Singapore dollars and Hong Kong dollars. In addition, a substantial portion of our capital expenditures, primarily for the

13

##### Table of Contents

purchase of packaging and testing equipment, has been, and is expected to continue to be, denominated in U.S. dollars with much of the remainder in Japanese yen. Fluctuations in exchange rates, primarily among the U.S. dollar, the NT dollar and the Japanese yen, will affect our costs and operating margins. In addition, these fluctuations could result in exchange losses and increased costs in NT dollar and other local currency terms. Despite hedging and mitigating techniques implemented by us, fluctuations in exchange rates have affected, and may continue to affect, our financial condition and results of operations. For example, we recorded foreign exchange losses of NT$935.5 million in 1998 and NT$538.4 million (US$17.2 million) in 1999, due primarily to losses attributable to Japanese yen-denominated liabilities created by us in the second half of 1998 to manage our foreign exchange exposure. We have closed our position on these Japanese yen-denominated liabilities as of November 5, 1999, and currently our foreign currency denominated liabilities are denominated principally in U.S. dollars.

The loss of a major customer or disruption of our strategic alliance with TSMC may result in a decline in our revenues and profitability.

Although we have over 200 customers, due in part to the concentration of market share in the semiconductor industry, we have derived and expect to continue to derive a large portion of our revenues from a small group of customers during any particular period. Our five largest customers together accounted for approximately 32.3%, 34.3%, 40.0% and 49.7% of our sales in 1997, 1998, 1999 and the six months ended June 30, 2000, respectively. Other than Motorola in 1999, no customer accounted for more than 10% of our net revenues in 1997, 1998 or 1999. For the six months ended June 30, 2000, no customer other than Motorola and VIA Technologies, Inc. accounted for more than 10% of our net revenues. In connection with our acquisition in July 1999 of Motorola’s in-house packaging and testing operations in Chung Li and Korea, we entered into manufacturing services agreements which expire in 2004 for Motorola’s continuing business at the Chung Li and Korea facilities. As a result, Motorola accounted for approximately 16% of our 1999 sales and approximately 25.6% of our sales for the first half of 2000. There has been significant variation in the composition of our largest five customers over time. This variation is due primarily to the high level of competition in the semiconductor industry in which our customers operate. The demand for our services from each customer is directly dependent upon that customer’s level of business activity, which could vary significantly from year to year. As a result, we have been less dependent on any particular customer over time.

Our strategic alliance with Taiwan Semiconductor Manufacturing Company Limited, the world’s largest dedicated semiconductor foundry, enables us to offer total semiconductor manufacturing services to our customers. This strategic alliance is terminable at will by either party. A termination of this strategic alliance, and our failure to enter into a substantially similar alliance, may adversely affect our competitiveness and our revenues and profitability.

All of our key customers operate in the cyclical semiconductor business and have in the past, and may in the future, vary order levels significantly from period to period. Moreover, over half of our customers are fabless semiconductor companies which outsource substantially all of their wafer fabrication and packaging requirements. Many of these companies are relatively small, have limited operating histories and financial resources, and are highly exposed to the cyclicality of the industry. We cannot assure you that these customers or any other customers will continue to place orders with us in the future at the same levels as in prior periods. The loss of one or more of our significant customers, or reduced orders by any one of them, and our inability to replace these customers or make up for such orders could reduce our profitability. In addition, we have in the past reduced, and may in the future be requested to reduce, our prices to limit the level of order cancellations. These price reductions would in turn be likely to reduce our margins and profitability.

We depend on our agents for sales and customer service in North America and Europe. Any serious interruption in our relationship with these agents, or substantial loss in their effectiveness, could significantly reduce our revenues and profitability.

We depend on non-exclusive agents for sales and customer service in North America and Europe. Our sales agents help us identify customers, monitor delivery acceptance and payment by customers and, within parameters set by us, help us negotiate price, delivery and other terms with our customers. Purchase orders are placed directly with us by our customers. Our customer service agents provide customer service and after-sales support to our customers.

Currently, our sales and customer service agents perform services only for us and ASE Test, our subsidiary, but they are not owned or controlled by us. These agents are free to perform sales and support services for others, including our competitors. In particular, we may not be able to find an adequate replacement for these agents or to develop sufficient capabilities internally on a timely basis. Any serious interruption in our relationship with these agents or substantial loss in their effectiveness in performing their sales and customer service functions could significantly reduce our revenues and profitability.

Our revenue and profitability may decline if we are unable to obtain adequate supplies of raw materials in a timely manner and at a reasonable price.

Our packaging operations require that we obtain adequate supplies of raw materials on a timely basis. Shortages in the supply of raw materials experienced by the semiconductor industry have in the past resulted in occasional price increases and delivery delays. For example, in 1997 and 1998, the industry experienced a shortage in the supply of advanced substrates used in ball grid array, or BGA, packaging. In 1997 we established ASE Material Inc., a company engaged in the development, production and sales of substrates and leadframes, to partially reduce this risk. However, ASE Material will not meet all of our raw materials requirements and consequently we will remain dependent on market supply and demand. We cannot assure you that we will be able to obtain adequate supplies of raw materials in a timely manner and at a reasonable price. Our revenues and earnings could decline if we were unable to obtain adequate supplies of high quality raw materials in a timely manner or if there were significant increases in the costs of raw materials that we could not pass on to our customers.

Any environmental claims or failure to comply with any present or future environmental regulations may require us to spend additional funds and may materially and adversely affect our financial condition and results of operations.

We are subject to a variety of laws and regulations relating to the use, storage, discharge and disposal of chemical by-products of, and water used in, our packaging process. Although we have not suffered material environmental claims in the past, the failure to comply with any present or future regulations could result in the assessment of damages or imposition of fines against us, suspension of production or a cessation of our operations. New regulations could require us to acquire costly equipment or to incur other significant expenses. Any failure on our part to control the use of, or adequately restrict the discharge of, hazardous substances could subject us to future liabilities that may have a material adverse effect on our financial condition and results of operations.

Our controlling shareholders may take actions that are not in, or may conflict with, our public shareholders’ best interest.

After this offering, members of the Chang family will own, directly or indirectly, a controlling interest of approximately 31% of our outstanding common shares. Accordingly, these

15

##### Table of Contents

shareholders will continue to have the ability to exercise a controlling influence over our business, including matters relating to:

| • | our management and policies;
| • | the timing and distribution of dividends; and
| • | the election of our directors and supervisors.

Members of the Chang family may take actions that you may not agree with or that are not in our or our public shareholders’ best interest.

We are an ROC company, and because the rights of shareholders under ROC law differ from those under U.S. law, you may have difficulty protecting your shareholder rights.

Our corporate affairs are governed by our Articles of Incorporation and by the laws governing corporations incorporated in the ROC. The rights of shareholders and the responsibilities of management and the members of the board of directors under ROC law are different from those applicable to a corporation incorporated in the United States. For example, directors and controlling shareholders of ROC companies do not owe fiduciary duties to minority shareholders. Therefore, public shareholders of ROC companies may have more difficulty in protecting their interest in connection with actions taken by management or members of the board of directors than they would as public shareholders of a U.S. corporation.

Risks Relating to Countries in Which We Conduct Operations

Risks Relating to Taiwan, Republic of China

| Strained relations between the Republic of China and the People’s Republic of China could negatively affect our business and the market value of your investment.

Our principal executive offices and our principal packaging and testing facilities are located in Taiwan and approximately 72% and 75% of our net revenues in 1999 and the six months ended June 30, 2000, respectively, from packaging and testing services are derived from our operations in Taiwan. The Republic of China has a unique international political status. Both the Republic of China and the People’s Republic of China assert sovereignty over all of China, including Taiwan. The People’s Republic of China government does not recognize the legitimacy of the Republic of China government. Although significant economic and cultural relations have been established in recent years between the Republic of China and the People’s Republic of China, relations have often been strained and the government of the People’s Republic of China government has indicated that it may use military force to gain control over Taiwan in some circumstances, such as the declaration of independence by the Republic of China. Relations between the Republic of China and the People’s Republic of China have been particularly strained in recent years. Following the results of the presidential elections for the Republic of China held on March 2000, the new President of the Republic of China was sworn in on May 20, 2000. We cannot predict how the election of the new President will affect relations between the two governments. Past developments in relations between the Republic of China and the People’s Republic of China have on occasion depressed the market price of the shares and ADSs of Taiwanese companies. Relations between the Republic of China and the People’s Republic of China and other factors affecting the political or economic conditions in Taiwan could have a material adverse effect on our financial condition and results of operations, as well as the market price and the liquidity of our ADSs and common shares.

| Because a substantial portion of our business and operations are located in Taiwan, a severe earthquake in the future could severely disrupt the normal operation of our business and adversely affect our earnings.

Taiwan is susceptible to earthquakes. On September 21, October 22 and November 2, 1999, Taiwan experienced severe earthquakes which caused significant property damage and loss of life, particularly in the central part of Taiwan. These earthquakes damaged production facilities and adversely affected the operations of many companies involved in the semiconductor and other industries. We experienced no structural damage to our facilities and no damage to our machinery and equipment as a result of these earthquakes. There were, however, interruptions to our production schedule primarily as a result of power outage caused by the earthquakes. Our production facilities as well as many of our suppliers and customers and providers of complementary semiconductor manufacturing services, including foundries, are located in Taiwan. If our customers are affected, it could result in a decline in the demand for our packaging and testing services. If our suppliers and providers of complementary semiconductor manufacturing services are affected, our production schedule could be interrupted or delayed. As a result, a major earthquake in Taiwan could severely disrupt the normal operation of business and have a material adverse effect on our financial condition and results of operations.

Risks Relating to Ownership of ADSs

If an active market for our ADSs fails to develop or be sustained, the price of our ADSs may fall.

Before this offering, there has been no market outside the ROC for our common shares and there has been no market for our ADSs anywhere. Following this offering, the Taiwan Stock Exchange will remain the only market for the common shares. Application has been made to list the ADSs on the New York Stock Exchange. We cannot predict the extent to which this offering will result in the development of an active, liquid public trading market for our ADSs or how liquid the market will be. Active, liquid trading markets generally result in lower price volatility and more efficient execution of buy and sell orders for investors, compared to less active and less liquid markets. Liquidity of a securities market is often a function of the volume of the underlying shares that are publicly held by unrelated parties.

Although ADS holders are entitled to withdraw the common shares underlying the ADSs from the depositary at any time, ROC law requires that the common shares be held in an account in the ROC or sold for the benefit of the holder on the Taiwan Stock Exchange. In connection with any withdrawal of common shares from our ADS facility, the ADSs evidencing these common shares will be cancelled. Unless additional ADSs are issued, the effect of withdrawals will be to reduce the number of outstanding ADSs and, if a significant number of withdrawals are effected, to reduce the liquidity of the ADSs. We cannot assure you that the ADS depositary will be able to arrange for a sale of deposited shares in a timely manner or at a specified price, particularly during periods of illiquidity or volatility with respect to our common shares.

As a holder of ADSs, your voting rights are limited by the terms of the deposit agreement. You will not be able to exercise your voting rights on an individual basis.

As a holder of ADRs evidencing ADSs, you will not be able to exercise voting rights on an individual basis. You may exercise your voting rights with respect to the underlying common shares only in accordance with the provisions of the deposit agreement. In particular, for any resolution to be proposed at a shareholders meeting, only holders who (1) have provided voting instructions in a timely manner in accordance with the provisions of the deposit agreement, and (2) together own at least 51% of the outstanding ADSs voting in the same manner, will be able to vote the common shares representing their ADSs in the manner set forth in their voting

17

##### Table of Contents

instructions. In all other cases, holders will be deemed to have authorized and directed the depositary to give a discretionary proxy to our Chairman or his designee to vote the common shares represented by their ADSs in any manner he or his designee may wish, which may not be in the interests of the holders.

During any period in which your ADSs represent the irrevocable right to receive our common shares evidenced by certificates of payment deposited with the custodian, you may exercise your voting rights in the same manner as if your ADSs represented our common shares.

You may not be able to participate in rights offerings and may experience dilution of your holdings.

We may, from time to time, distribute rights to our shareholders, including rights to acquire securities. Under the deposit agreement, the depositary will not distribute rights to holders of ADSs unless the distribution and sale of rights and the securities to which these rights relate are either exempt from registration under the Securities Act of 1933 with respect to all holders of ADSs, or are registered under the provisions of the Securities Act. We can give no assurances that we can establish an exemption from registration under the Securities Act, and we are under no obligation to file a registration statement with respect to these rights or underlying securities or to endeavor to have a registration statement declared effective. In addition, if the depositary is unable to obtain the requisite approval from the Central Bank of China for the conversion of the subscription payments into NT dollars or if the depositary determines that it is unlikely to obtain the required approval, we may decide with the depositary not to make the rights available to holders of ADSs. See “— Risks Relating to Ownership of ADSs — Changes in exchange controls which restrict your ability to convert proceeds received from your ownership of ADSs may have an adverse effect on the value of your investment” and “Annex B — Foreign Investment and Exchange Controls in the ROC” in this prospectus. Accordingly, holders of ADSs may be unable to participate in our rights offerings and may experience dilution of their holdings as a result.

If the depositary is unable to sell rights that are not exercised or not distributed or if the sale is not lawful or reasonably practicable, it will allow the rights to lapse, in which case you will receive no value for these rights.

The value of your investment may be reduced by possible future sales of common shares by us or our shareholders.

Except for the sale of additional ADSs to the underwriters, we and some of our shareholders have agreed with the underwriters not to dispose of any of our common shares or securities convertible into or exchangeable for common shares, including ADSs, during the period beginning from the date of this prospectus continuing through the date 90 days after the date of this prospectus, except with the prior written consent of the representatives of the underwriters. Approximately 555.6 million common shares are subject to the lock-up agreement. The representatives may, in their discretion, waive or terminate these restrictions. See “Common Shares Available for Future Sale” for a discussion of restrictions that may apply to future sales of our ADSs or common shares by us and our affiliates.

While we are not aware of any plans by any major shareholders to dispose of significant numbers of common shares, we cannot assure you that one or more existing shareholders or owners of securities convertible or exchangeable into or exercisable for our common shares will not dispose of significant numbers of common shares. In addition, following completion of this offering, several of our subsidiaries and affiliates will continue to hold common shares, depositary shares representing common shares and options to purchase common shares. We or they may decide to sell those securities in the future. See “Principal Shareholders” for a description of our significant shareholders and ASE Group companies that hold our common shares. We cannot predict the effect, if any, that future sales of ADSs or common shares, or the availability of ADSs

18

##### Table of Contents

or common shares for future sale, will have on the market price of ADSs or common shares prevailing from time to time. Sales of substantial amounts of ADSs or common shares in the public market, or the perception that future sales may occur, could depress the prevailing market price of our ADSs or common shares.

Changes in exchange controls which restrict your ability to convert proceeds received from your ownership of ADSs may have an adverse effect on the value of your investment.

Under current ROC law, the depositary, without obtaining further approvals from the Central Bank of China or any other governmental authority or agency of the ROC, may convert NT dollars into other currencies, including U.S. dollars, for:

| • | the proceeds of the sale of common shares represented by ADSs or received as stock dividends from the common shares; and
| • | any cash dividends or distributions received from the common shares.

In addition, the depositary may also convert into NT dollars incoming payments for purchases of common shares for deposit in the depositary receipt facility against the creation of additional ADSs. The depositary is required to obtain approval from the Central Bank of China on a payment-by-payment basis for conversion into NT dollars of subscription payments for rights offerings. The depositary may also be required to obtain foreign exchange approval from the Central Bank of China on a payment-by-payment basis for conversion from NT dollars into foreign currencies of the proceeds from the sale of subscription rights of new common shares. Although it is expected that the Central Bank of China will grant this approval as a routine matter, we cannot assure you that in the future any approval will be obtained in a timely manner, or at all.

Under current ROC law, a holder, without obtaining further approval from the Central Bank of China, may convert from NT dollars into other currencies, including U.S. dollars, the following:

| • | the proceeds of the sale of any underlying common shares withdrawn from the depositary receipt facility or received as a stock dividend; and
| • | any cash dividends or distribution received.

Under the ROC Foreign Exchange Control Law, the Executive Yuan of the ROC government may, without prior notice but subject to subsequent legislative approval, impose foreign exchange controls in the event of, among others, a material change in international economic conditions. We cannot assure you that foreign exchange controls or other restrictions will not be introduced in the future.

The market value of your investment may fluctuate due to the volatility of the ROC securities market.

The ROC securities market is smaller and more volatile than the securities markets in the United States and in other European countries. The Taiwan Stock Exchange has experienced substantial fluctuations in the prices and volumes of sales of listed securities and there are currently limits on the range of daily price movements on the Taiwan Stock Exchange. In the past ten years, the Taiwan Stock Exchange Index peaked at 12,495.3 in February 1990, and subsequently fell to a low of 2,560.5 in October 1990. On September 8, 2000, the Taiwan Stock Exchange Index closed at 7,367.99. The Taiwan Stock Exchange has experienced problems such as market manipulation, insider trading and payment defaults. The recurrence of these or similar problems could have a material adverse effect on the market price and liquidity of the securities of ROC companies, including our ADSs and common shares, in both the domestic and the international markets.

You will not be able to withdraw the underlying common shares of our ADSs for a period of three months after the initial delivery of the ADSs.

Under ROC regulations applicable to offerings of ADSs, newly-issued shares of ROC companies initially offered in ADS form may not be withdrawn from the ADS facility until three months following the initial delivery of the ADSs. As a result, for a period of three months following closing of this offering, owners of the ADSs offered by this prospectus will not be able to withdraw the underlying common shares from our ADS facility or sell the underlying common shares on the Taiwan Stock Exchange. Although the common shares that will be represented by the ADSs, if any, purchased by the underwriters pursuant to the exercise of their over-allotment option will not be newly-issued common shares, those ADSs will not be distinguishable from the other ADSs being offered in this offering and consequently will be subject to the same restrictions on withdrawal of the underlying common shares for this three-month period.

You may have difficulty enforcing any judgment obtained in the United States against us or our directors and supervisors or executive officers.

Our company is incorporated under the laws of the ROC. Substantially all of our directors, supervisors and executive officers reside in the ROC. In addition, a substantial portion of our assets and the assets of those persons are located in the ROC. As a result, it may not be possible for investors to effect service of process upon us or those persons within the United States, or it may be difficult to enforce against us or them judgments obtained in the U.S. courts, including those based upon the civil liability provisions of the federal securities laws of the United States. In addition, we have been advised by Lee and Li, our ROC counsel, that there is doubt as to whether ROC courts will enter judgments in original actions brought in ROC courts based solely upon the civil liability provisions of the federal securities laws of the United States. See “Enforceability of Civil Liabilities”.

Purchasers of ADSs may incur dilution as a result of the practice among ROC technology companies of issuing stock bonuses to employees.

Similar to other ROC technology companies, we issue from time to time bonuses in the form of common shares valued at par under our employee stock bonus plan. Because these shares are issued at par value, the issuance of these shares may have a dilutive effect on your ADSs.

FORWARD-LOOKING STATEMENTS

This prospectus and information incorporated by reference includes forward-looking statements. These statements are generally indicated by the use of forward-looking terminology such as believe, expect, anticipate, estimate, plan, project, may, will or other similar words that express an indication of actions or results of actions that may or are expected to occur in the future. You should not place undue reliance on these forward-looking statements, which apply only as of the date of this prospectus. These forward-looking statements are based on our own information and on information from other sources we believe to be reliable. Some of these forward-looking statements are derived from projections made and published by Dataquest and Electronic Trend Publications. We were not involved in the preparation of these projections. Our actual results may be materially less favorable than those expressed or implied by these forward-looking statements as a result of risks and other factors noted throughout this prospectus which could depress the market price of our ADSs and common shares.

USE OF PROCEEDS

The net proceeds of this offering will be approximately US$169.8 million (assuming an initial offering price of US$8.92 per ADS, which is based on the U.S. dollar equivalent of the closing price of the common shares on the Taiwan Stock Exchange on September 8, 2000 multiplied by five), after we deduct underwriting and estimated offering expenses, or US$193.5 million if the underwriters’ over-allotment option is exercised in full.

We intend to use the net proceeds in the following manner:

| • | US$128.0 million for the purchase of new machinery and equipment;
| • | US$40.0 million for the construction of new facilities in connection with the expansion of our facilities in Kaohsiung (not including those of our subsidiaries); and
| • | the remainder for working capital and general corporate purposes.

Pending these uses, we expect to invest the net proceeds in short-term, interest-bearing securities or may use a portion of the funds temporarily for working capital or general corporate purposes.

The performance of the Taiwan Stock Exchange has in recent years been characterized by extreme price volatility. There are currently limits on the range of daily price movements on the Taiwan Stock Exchange. See “Annex A — The Securities Markets of the ROC — The Taiwan Stock Exchange”.

Based on records maintained on behalf of our share registrar by the central depositary organization for the clearance and settlement of securities traded on the Taiwan Stock Exchange, and information provided to us by brokers, dealers and banks or their nominees in the ROC, including the custodian of shares underlying depositary receipts, whose customers hold our common shares, we believe that, as of August 15, 2000, fewer than 300 of our shareholders were resident in the United States.

Each GDS represents five common shares of ASE Inc. The GDSs sold under Rule 144A have been designated as eligible for trading in the PORTAL System of the National Association of Securities Dealers, Inc. in the United States. The GDSs sold pursuant to Regulation S are listed on the Stock Exchange of Singapore and the Luxembourg Stock Exchange and quoted on SEAQ International. Some of our affiliates offered and sold an additional 10,489,902 GDSs in December 1999. As of August 24, 2000, there was an aggregate of 18,412,858 GDSs outstanding comprising 10,497,527 GDSs sold pursuant to Regulation S, 5,805,233 GDSs sold under Rule 144A and 2,110,098 GDSs held by our affiliates, which do not include the 5.8 million GDSs to be distributed as stock dividends to GDS holders of record on August 13, 2000. Concurrently with this offering, we are offering to exchange one ADS for each GDS sold under Rule 144A. We are also arranging for the automatic conversion of each of the outstanding GDSs sold pursuant to Regulation S into one ADS. The conversion of and exchange for the GDSs into ADSs are conditional upon closing of this offering. Upon completion of the conversion of the GDSs sold pursuant to Regulation S into ADSs, we intend to delist these GDSs from the Stock Exchange of Singapore and the Luxembourg Stock Exchange.

The following table sets forth the aggregate number of outstanding common shares entitled to dividends, as well as the stock dividends paid during each of the years indicated.

(1) | Holders of common shares receive as a stock dividend the number of common shares equal to the NT dollar value per common share of the dividend declared multiplied by the number of common shares owned and divided by the par value of NT$10 per share. Fractional shares are not issued but are paid in cash.
(2) | Aggregate number of common shares outstanding on the record date applicable to the dividend payment. Includes common shares issued in the previous year under our employee bonus plan.
(3) | Includes 43,000,000 common shares issued in connection with an offering of GDSs in July 1995.

We have historically paid stock dividends on our common shares with respect to the preceding year after approval by our shareholders at the annual general meeting of shareholders. Our most recent stock dividend of NT$3.15 per common share will be distributed in October 2000 to shareholders of record on August 13, 2000. The form, frequency and amount of future cash or stock dividends on our common shares and ADSs will depend upon our earnings, cash flow, financial condition and other factors. See “Description of Common Shares — Dividends and Distributions” and Note 15 of Notes to Consolidated Financial Statements.

In general, we are not permitted to distribute dividends or make other distributions to shareholders for any year in which we did not record net income. The ROC Company Law also requires that 10% of annual net income (less prior years’ losses, if any) be set aside as a legal reserve until the accumulated legal reserve equals our paid-in capital. In addition, our Articles of Incorporation require that before a dividend is paid out of our annual net income:

| • | up to 2% of our annual net income (less any gains on the disposal of fixed assets, prior years’ losses and additions to legal and special reserves, if any) should be paid to our directors and supervisors as compensation; and
| • | between 5% and 7% of the annual net income (less any gains on the disposal of fixed assets, prior years’ losses and legal and special reserves, if any) should be paid to our employees as bonuses. The 5% portion is to be distributed to all employees in the form of stock bonuses in accordance with our employee stock bonus plan, while any portion

|  | exceeding 5% is to be distributed in accordance with rules established by our board of directors to individual employees who have been recognized as having made special contributions to our company.

Holders of ADSs will be entitled to receive dividends, subject to the terms of the deposit agreement, to the same extent as the holders of the common shares. Cash dividends will be paid to the depositary in NT dollars and, except as otherwise described under “Description of American Depositary Receipts — Dividends and Distributions — Distributions of Cash”, will be converted by the depositary into U.S. dollars and paid to holders of ADSs according to the terms of the deposit agreement. Stock dividends will be distributed to the depositary and, except as otherwise described under “Description of American Depositary Receipts — Dividends and Distributions — Distributions of Shares”, will be distributed by the depositary, in the form of additional ADSs, to holders of ADSs according to the terms of the deposit agreement.

Holders of outstanding common shares on a dividend record date will be entitled to the full dividend declared without regard to any prior or subsequent transfer of common shares. Accordingly, purchasers of ADSs holding outstanding ADSs on the relevant dividend record date will, subject to the terms of the deposit agreement, be entitled to the full amount of any dividend declared at our next general meeting of the shareholders.

For information relating to ROC withholding taxes payable on dividends, see “Taxation — ROC Taxation — Dividends”. For information relating to ROC foreign exchange approvals required for the conversion by the depositary of dividends on common shares from NT dollars into U.S. dollars for the payment to holders of ADSs, see “Annex B — Foreign Investment and Exchange Controls in the ROC — Depositary Receipts”.

EXCHANGE RATES

Fluctuations in the exchange rate between NT dollars and U.S. dollars will affect the U.S. dollar equivalent of the NT dollar price of the common shares on the Taiwan Stock Exchange and, as a result, will likely affect the market price of the ADSs. Fluctuations will also affect the U.S. dollar conversion by the depositary of cash dividends paid in NT dollars on, and the NT dollar proceeds received by the depositary from any sale of, common shares represented by ADSs, in each case, according to the terms of the deposit agreement.

The following table sets forth, for the fiscal years indicated, information concerning the number of NT dollars for which one U.S. dollar could be exchanged based on the noon buying rate for cable transfers in NT dollars as certified for customs purposes by the Federal Reserve Bank of New York.

Unless otherwise noted, all translations from NT dollars to U.S. dollars and from U.S. dollars to NT dollars were made at the noon buying rate in The City of New York for cable transfers in NT dollars per U.S. dollar as certified for customs purposes by the Federal Reserve Bank of New York as of June 30, 2000, which was NT$30.80 to US$1.00 on that date. No representation is made that the NT dollar or U.S. dollar amounts referred to in this prospectus could have been or could be converted into U.S. dollars or NT dollars, as the case may be, at any particular rate or at all. On September 8, 2000, the noon buying rate was NT$31.10 to US$1.00.

The table assumes no exercise of the underwriters’ over-allotment option. Except as set forth below, there has been no material change in our consolidated short-term debt and capitalization since June 30, 2000.

DILUTION

As of June 30, 2000, we had a net tangible book value of US$0.40 per common share. Net tangible book value per common share is determined by dividing our net tangible book value determined in accordance with ROC GAAP (total tangible assets less total liabilities) by the total number of outstanding common shares issued as of June 30, 2000 and stock dividend shares and employee bonus shares to be issued in October 2000, and using an exchange rate of NT$30.80 per US$1.00. Our net tangible book value per ADS on that date was US$2.01 per ADS. This is calculated by multiplying our net tangible book value per common share by five, which is the number of common shares represented by each ADS. After giving effect to the sale by ASE Inc. of 20,000,000 ADSs at an assumed initial offering price of US$8.92 per ADS (which is based on the U.S. dollar equivalent of the closing price of the common shares on the Taiwan Stock Exchange on September 8, 2000 multiplied by five), and after deducting estimated underwriting discounts and estimated expenses to be paid by us, our pro forma net tangible book value per ADS as of June 30, 2000 would have been US$2.24 per ADS. This represents an immediate dilution of US$6.68 per ADS to new investors purchasing ADSs in this offering and an immediate increase in pro forma net tangible book value of US$0.23 per ADS to our existing shareholders. The following table illustrates this per ADS dilution:

Assumed initial offering price per ADS |  |  |  |  |  |  | US$8.92 |
| Net tangible book value per ADS equivalent at June 30, 2000 |  |  | US$2.01 |  |  |  |  |
| Increase per ADS attributable to new investors |  |  | US$0.23 |  |  |  |  |
Net tangible book value per ADS after the offering |  |  |  |  |  |  | US$2.24 |
Dilution per ADS to new investors |  |  |  |  |  |  | US$6.68 |

The following table sets forth, as of June 30, 2000, on a pro forma basis after giving effect to this offering:

| (1) | the total number of ADS equivalents, or units of five common shares, held by our current shareholders and the total consideration and the average price per ADS equivalent paid for ADS equivalents to be issued by us in this offering;
| (2) | the total consideration for the ADSs to be issued by ASE Inc. and the price to be paid by you and the other purchasers of ADSs in this offering, before deducting the estimated underwriting discounts and offering expenses payable by us, at the initial offering price of US$8.92 per ADS; and

| (3) | the percentage of ADSs purchased and the percentage of total consideration paid by our current shareholders and the new investors, using an exchange rate of NT$30.80 per US$1.00:

|  | ADSs or ADS |  |  |  |
|  | Equivalents Purchased |  | Total Consideration |  | Average Price
|  |  |  |  |  | per ADS or ADS
|  | Number |  | Percent |  | Amount |  | Percent |  | Equivalent
Existing shareholders |  |  | 530,400,000 |  |  |  | 96.4 | % |  | US$ | 780,550,543.4 |  |  |  | 81.4 | % |  | US$ | 1.47 |
New investors in the offering |  |  | 20,000,000 |  |  |  | 3.6 |  |  |  | 178,400,000.0 |  |  |  | 18.6 |  |  |  | 8.92 |
| Total |  |  | 550,400,000 |  |  |  | 100.0 | % |  | US$ | 958,950,543.4 |  |  |  | 100.0 | % |  |  |  |

MANAGEMENT’S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION

AND RESULTS OF OPERATIONS

The following discussion of our business, financial condition and results of operations should be read in conjunction with the Consolidated Financial Statements, the combined financial statements of Motorola’s Semiconductor Products Sector Businesses in Taiwan and Korea and the unaudited pro forma financial statements, all of which are included elsewhere in this prospectus. This discussion contains forward-looking statements that reflect our current views with respect to future events and financial performance. Our actual results may differ materially from those anticipated in these forward-looking statements as a result of any number of factors, such as those set forth under “Risk Factors” and elsewhere in this prospectus.

Overview

We offer a broad range of semiconductor packaging and testing services. In addition to offering each service separately, we also offer turnkey services, which is the integrated packaging, testing and direct shipment of semiconductors to end users designated by our customers. Our net revenues have increased significantly from NT$19,088.2 million in 1997 to NT$32,609.6 million (US$1,058.7 million) in 1999. After eliminating the results of the operations we acquired in 1999 for comparative purposes, our net revenues were NT$25,147.9 million (US$816.5 million) in 1999. For the six months ended June 30, 2000, our net revenues were NT$23,597.2 million (US$766.1 million) compared to NT$11,913.7 million for the same period in 1999. After eliminating the results of the operations we acquired in 1999 for comparative purposes, our net revenues for the six months ended June 30, 2000 were NT$17,744.0 million (US$576.1 million). Following an industry downturn in 1998, we are currently enjoying strong revenue growth and improved profitability with the recent upturn in the semiconductor industry. Our growth is increasingly diversified across a broad range of end user applications and clients. We are experiencing strong growth in communications and consumer-related sectors while maintaining our strong market position in personal computer-related sectors. Our volume growth is increasingly concentrated in the packaging of higher priced package types and the testing of more complex semiconductor devices.

We price our services based primarily on a cost-plus calculation of the costs involved in providing these services, and with reference to market prices. The majority of our prices and revenues are denominated in U.S. dollars. However, as more than half of our costs, including all labor and overhead costs, are denominated in NT dollars, we consider the NT dollar to be our functional currency. Furthermore, the majority of our financing costs are denominated in NT dollars. The average realized selling price for packaging a semiconductor device is higher than the average realized selling price for the final testing of the same device. Over the last three years, our testing revenues have grown faster than our packaging sales. In 1997, 1998, 1999 and the six months ended June 30, 2000, our packaging sales accounted for 80.3%, 81.2%, 75.2% and 75.1%, while testing revenues accounted for 12.5%, 15.1%, 23.9% and 24.5%, respectively, of our net revenues. After eliminating the results of the operations we acquired in 1999 for comparative purposes, testing revenues as a percentage of net revenues in 1999 and the six months ended June 30, 2000, at 16.1% and 17.0%, respectively, were still higher than the corresponding levels in 1999. We expect this trend to continue as industry trends suggest a higher growth rate for testing compared to packaging services. The portion of the semiconductor testing market currently accounted for by independent testing service providers is smaller than that for packaging, which we believe will facilitate outsourced testing to grow at a faster rate than packaging. In addition, the high capital expenditures needed for increasingly complex testing equipment, as compared to less expensive packaging equipment, is leading to further outsourcing of testing services by integrated device manufacturers. We also expect to provide increasingly more turnkey services to our clients.

##### Table of Contents

Our results of operations have been affected by a number of factors, including the proportionate contribution of packaging and testing to our net revenues, our capacity utilization rates and the costs of raw materials. Over the last three years, our net revenues have been affected by the volume of units packaged and tested, the selling prices for these units, and currency fluctuations. In 1999, our results of operations were affected by our acquisition in May 1999 of 70% of the outstanding shares of ISE Labs, our acquisitions in July 1999 of ASE Chung Li and ASE Korea and our purchase from February through July 1999, in the open market, of a controlling 22.6% stake in Universal Scientific. Our interest in ISE Labs was subsequently increased to 75.3% following ASE Test’s purchase of $30 million of additional shares of ISE Labs in April 2000. In addition, we subsequently increased our ownership interest in Universal Scientific to 23.3% through the purchase of additional shares in the open market in July and August of 2000.

Pricing and Revenue Mix

The semiconductor industry is characterized by a general trend towards declining prices for products and services of a given technology over time. During times of intense competition and adverse conditions in the semiconductor industry, such as in 1998, the pace of this decline in prices of our services may be more rapid than that experienced in other years. In 1998, the selling prices in U.S. dollar terms of our packaging and testing services experienced a sharp decline due to intense price competition from other independent packaging and testing companies that were attempting to maintain capacity utilization levels in the face of reduced demand.

Declines in selling prices have been partially offset over the last three years by a change in our revenue mix. In particular, we have been packaging more higher-priced package types, such as ball grid array, also called BGA, and advanced thin quad flat packages, also called TQFPs, and testing more complex semiconductor devices. We will continue to develop and offer new technology in packaging and testing services, as well as improve production efficiencies for older technology, in order to mitigate the effects of declining prices on our profitability.

High Fixed Costs

Our operations are capital intensive and are characterized by relatively high fixed costs. Our primary fixed costs are for packaging and testing equipment. Increases or decreases in capacity utilization rates can have a significant effect on gross profit margins, as the unit cost of packaging and testing services generally decreases as fixed charges, such as equipment depreciation expense, are allocated over a larger number of units. Depreciation is the principal component of our cost of testing revenues. Testers typically cost between US$2.0 million and US$3.0 million each, while wire bonders used in packaging typically cost approximately US$100,000 each. In 1997, 1998, 1999 and the six months ended June 30, 2000, our depreciation expense as a percentage of net revenues was 10.5%, 14.9%, 16.3% and 15.1%, respectively. The rise in depreciation expense partially reflects the increased contribution of testing to net revenues, as well as an increase in the cost of packaging and testing equipment. We begin depreciating our equipment when it is placed into service. There may sometimes be a time lag between when our equipment is placed into service and when it achieves high levels of utilization. This was the case in 1998, when depressed industry conditions resulted in lower than expected demand from customers and a sharp decline in selling prices, resulting in an increase in depreciation expense relative to sales. With the improvement in industry conditions at the end of 1998, utilization levels improved, along with a recovery in profitability.

Raw Material Costs

Substantially all of our raw material costs are accounted for by packaging, as testing requires minimal materials. In 1997, 1998, 1999 and the six months ended June 30, 2000, raw

32

##### Table of Contents

material cost as a percentage of our net revenues was 38.2%, 34.9%, 30.0% and 29.2%, respectively. Raw material cost as a proportion of net revenues has been decreasing because of the higher contribution of testing to net revenues and, in 1999 and the six months ended June 30, 2000, a decrease in raw material prices. However, we expect raw materials to become an increasingly important component of the cost of our packaging sales and we plan to continue our development and production of interconnect material through ASE Material in order to help ensure an adequate supply of raw materials at competitive prices and reduce production time.

Our operating and non-operating income in recent years have been affected by goodwill amortization charges in connection with acquisitions, the restructuring of our investment holdings and other share repurchases. Under generally accepted accounting principles in the ROC, additional purchases of shares of consolidated subsidiaries (majority owned) or of companies accounted for using the equity method (less than majority but greater than 20% owned) will generate goodwill in an amount equal to the difference between the purchase price and the book value per share of those shares. The goodwill generated is amortized over ten years. Goodwill generated on the purchases of shares of consolidated subsidiaries are recognized under general administrative and selling expense. Goodwill generated on the purchases of shares of companies which are less than majority but greater than 20% owned, and therefore accounted for using the equity method, are recognized as a debit under investment income. In addition to the acquisitions of ASE Korea and ISE Labs, other transactions which created significant goodwill charges were the open-market purchases of 22.6% of Universal Scientific shares in 1999, as well as the open-market purchases of ASE Test shares by a wholly-owned subsidiary as part of a share repurchase program in the period from December 1997 through March 1998. No goodwill was recognized in connection with the acquisition of ASE Chung Li, which was structured as an asset purchase, due to the appreciation of the fixed assets purchased.

Consolidation of ISE Labs, ASE Chung Li and ASE Korea

Under the method of consolidation used by us to consolidate the statements of income of ISE Labs, ASE Chung Li and ASE Korea for the year ended December 31, 1999: (1) ISE Labs’ full-year 1999 net revenues, cost of revenues and operating expenses are included in the Consolidated Financial Statements, and the pre-acquisition income of ISE Labs for the year ended December 31, 1999 (from January 1 to May 4, 1999) is then subtracted from our net income for 1999; and (2) the net revenues, cost of revenues, operating expenses and net income of ASE Chung Li and ASE Korea are included in the Consolidated Financial Statements since the date of acquisition. Under the method of consolidation used by ASE Test to consolidate the statement of income of ISE Labs for the year ended December 31, 1999, ISE Labs’ pre-acquisition net revenues, cost of revenues and operating expenses are not included in ASE Test’s consolidated income statement. See Notes 2 and 28f of Notes to Consolidated Financial Statements.

| Six Months Ended June 30, 2000 Compared to Six Months Ended June 30, 1999

Net Revenues. Our net revenues increased by 98.1% to NT$23,597.2 million (US$766.1 million) for the six months ended June 30, 2000 from NT$11,913.7 million for the comparable period in 1999, reflecting increases in net revenues at our existing facilities, as well as the effects of the acquisitions of ASE Chung Li and ASE Korea in July 1999. After eliminating the results of ASE Chung Li and ASE Korea for comparative purposes, our net revenues for the six months ended June 30, 2000, which we call our adjusted net revenues, was NT$17,744.0 million (US$576.1 million), a 48.9% increase over our net revenues reported for the comparable period in 1999, reflecting a 49.8% increase in packaging sales and a 53.7% increase in testing revenues. This increase in our adjusted net revenues for the six months ended June 30, 2000 compared to the comparable period in 1999 resulted primarily from an increase in packaging and testing volume, which was partially offset by a decrease in the average realized selling prices for our packaging and testing services.

Gross Profit. Our gross profit increased by 155.0% to NT$7,320.5 million (US$237.7 million) for the six months ended June 30, 2000 from NT$2,870.3 million for the comparable period in 1999, reflecting increases in gross profit at our existing facilities, as well as the effects of the acquisitions of ASE Chung Li and ASE Korea. After eliminating the results of ASE Chung Li and ASE Korea for comparative purposes, our gross profit for the six months ended June 30, 2000 increased by 92.5% over our gross profit reported for the comparable period in 1999. Our adjusted gross margin increased to 31.1% compared to 24.1% for the comparable period in 1999 primarily as a result of decreases in raw material costs and depreciation expense, which were partially offset by increases in equipment maintenance expense, all as a percentage of net revenues. Raw material costs as a percentage of net revenues decreased primarily as a result of lower substrate costs. Depreciation expense decreased as a percentage of net revenues primarily as a result of increased capacity utilization at our packaging and testing facilities.

Our adjusted gross margin for packaging increased to 27.1% in the six months ended June 30, 2000 from 21.0% in the comparable period in 1999, primarily due to increased capacity utilization at our packaging facilities and a decrease in raw material costs as a percentage of net revenues. Our gross margin for packaging in the six months ended June 30, 2000 was 27.6%, reflecting the higher packaging margins at the ASE Chung Li facilities acquired in 1999, partially offset by the lower packaging margins at the ASE Korea facilities acquired in 1999. Our adjusted gross margin for testing increased to 46.0% from 41.0% primarily due to a decrease in labor costs as a percentage of net revenues and increased capacity utilization at our testing facilities. Our gross margin for testing in the six months ended June 30, 2000 was 43.1%, reflecting the lower testing margins at our facilities acquired in 1999.

Operating Income. Our operating income increased 269.9% to NT$4,731.9 million (US$153.6 million) in the six months ended June 30, 2000 from NT$1,279.1 million for the comparable period in 1999, reflecting increases in operating income at our existing facilities, as well as the acquisition of ASE Chung Li and ASE Korea. After eliminating the results of ASE Chung Li and ASE Korea for comparative purposes, our operating income increased by 169.5% in the six months ended June 30, 2000 compared to the comparable period in 1999. Our operating margin increased to 20.1% in the six months ended June 30, 2000 from 10.7% in the comparable period in 1999. After eliminating the results of ASE Chung Li and ASE Korea for comparative purposes, our adjusted operating margin increased to 19.4% compared to 10.7% for 1999, reflecting the higher adjusted gross margin and decreases in selling expense, travel and entertainment costs, depreciation expense and other selling costs, partially offset by increases in salaries and bonuses, all as a percentage of net revenues.

Net Non-Operating Income. Our net non-operating loss was NT$707.8 million (US$23.0 million) in the six months ended June 30, 2000, compared to net non-operating gain of

35

##### Table of Contents

NT$3,688.3 million in the comparable period in 1999. This was primarily a result of a decrease in capital gains realized on long-term investment, partially offset by an increase in investment income realized from Universal Scientific. The capital gains realized in the six months ended June 30, 1999, in the amount of NT$3,884.8 million, resulted primarily from the sale of ASE Test ordinary shares by J&R Holding in the form of Taiwan Depositary Receipts in 1999. Net foreign exchange gains in both periods were created by the unrealized gains on foreign exchange denominated liabilities resulting from the appreciation of the NT dollar. The gains in the six months ended June 30, 2000 were slightly lower because of the depreciation of the NT dollar in the second quarter of 2000. Net interest expense increased in the six months ended June 30, 2000 compared to the comparable period in 1999 primarily as a result of interest expense relating to the US$160 million 1% guaranteed convertible notes due 2004 issued by ASE Test Finance Limited, a wholly-owned subsidiary of ASE Test, in June 1999 and other long-term loans to finance the costs of our acquisitions of ISE Labs, ASE Chung Li, ASE Korea and a controlling interest in Universal Scientific.

Net Income. Our net income for the six months ended June 30, 2000 was NT$2,920.8 million (US$94.8 million) compared to NT$4,516.8 million for the comparable period in 1999. After eliminating the results of ASE Chung Li and ASE Korea, our adjusted net income for the six months ended June 30, 2000 was NT$1,832.5 million. Our net income and adjusted net income decreased in the six months ended June 30, 2000 compared to the comparable period in 1999 primarily because we had a significant net non-operating gain in the six months ended June 30, 1999 compared to a net non-operating loss in the comparable period in 2000. Excluding the extraordinary capital gains recognized in the six months ended June 30, 1999, our net income would have been NT$632.0 million for that period compared to net income of NT$2,920.8 million and adjusted net income of NT$1,832.5 million for the comparable period in 2000, representing a 362% increase in our net income and a 190% increase in our adjusted net income. The increase in recurring net income for the six months ended June 30, 2000 was due to the foregoing factors, partially offset by an increase in our effective tax rate to 12.4% in the six months ended June 30, 2000 compared to 3.3% in the comparable period in 1999. The low tax rate in 1999 primarily reflects the fact that capital gains are not subject to corporate income tax in the ROC.

Year Ended December 31, 1999 Compared to Year Ended December 31, 1998

Net Revenues. Our net revenues increased by 57.1% to NT$32,609.6 million (US$1,058.7 million) in 1999 from NT$20,762.4 million in 1998, reflecting in part the effects of the acquisitions of ISE Labs in May 1999 and ASE Chung Li and ASE Korea in July 1999, as well as increases in net revenues at our existing facilities. For a discussion of the consolidation principles relating to our acquisitions of ISE Labs, ASE Chung Li and ASE Korea, see Note 2 of Notes to Consolidated Financial Statements. After eliminating the results of ISE Labs, ASE Chung Li and ASE Korea for comparative purposes, our net revenues for 1999 increased by 21.1% in 1999 compared to 1998, reflecting a 23.3% increase in packaging sales and a 29.7% increase in testing revenues. This increase was partially offset by a decrease in revenues attributable to our subsidiary that designs and assembles notebook computers, set-top boxes and liquid crystal display monitors, and assembles board and sub-systems, ASE Technologies Inc., due primarily to the continuing loss of one of its major customers in 1999. ASE Technologies intends to wind down its business upon approval by its shareholders in September 2000. See “Business — Other Members of the ASE Group” for more information on ASE Technologies. In 1999, our adjusted packaging revenues accounted for 82.7% of our adjusted net revenues and our adjusted testing revenues accounted for 16.1% of our adjusted net revenues, compared to 81.2% and 15.1%, respectively, for 1998. The increase in our adjusted net revenues for 1999 compared to 1998 resulted primarily from an increase in packaging and testing volumes, which was partially offset by a decrease in the average realized selling prices for our packaging and testing services. The decrease in the average realized selling prices reflected the general trend in the semiconductor industry of

36

##### Table of Contents

declining prices for each input/ output lead on a semiconductor device. This decrease was partially offset by a change in our revenue mix as our BGA packages, which typically command higher selling prices as a result of the higher number of leads per device, accounted for a greater portion of our packaging volume, and as we tested more complicated semiconductor devices.

Gross Profit. Our gross profit increased by 63.4% to NT$8,650.0 million (US$280.8 million) in 1999 from NT$5,294.3 million in 1998, reflecting the effects of the acquisitions of ISE Labs, ASE Chung Li and ASE Korea, as well as increases in gross profit at our existing facilities. After eliminating the results of ISE Labs, ASE Chung Li and ASE Korea for comparative purposes, our gross profit increased by 28.2% in 1999 compared to 1998. Our adjusted gross margin increased to 27.0% compared to 25.5% for 1998 primarily as a result of decreases in raw material and labor costs, which were partially offset by increases in depreciation, factory supplies and other manufacturing overheads, as well as a decrease in provision for inventory obsolescence, all as a percentage of net revenues. Depreciation increased and raw material costs decreased as a percentage of net revenues primarily as a result of a change in our revenue mix, as testing services, which incur significant depreciation but almost no raw material costs, accounted for a greater portion of our net revenues, and a decrease in raw material prices. Cost of revenues also increased due to increases in factory supplies such as rinsing agents and manufacturing overhead and development costs associated with the ramp-up in BGA production capabilities. Our adjusted gross margin for packaging increased to 24.8% in 1999 from 21.9% in 1998 primarily due to decreases in direct and indirect labor and raw material costs as percentages of packaging revenue. Our gross margin for packaging in 1999 was 23.5%, compared with our adjusted gross margin for packaging of 24.8% for the same year, reflecting lower packaging margins at our facilities acquired in 1999 due to differences in product mix. Our adjusted gross margin for testing decreased to 45.2% from 47.4% in 1998 primarily due to increases in depreciation and amortization and other manufacturing costs, partially offset by a decrease in direct and indirect labor cost, all as percentages of testing revenue. Our gross margin for testing in 1999 was 39.8%, as compared to our adjusted gross margin for testing of 45.2% for the same year, reflecting lower testing margins at the facilities acquired in 1999 due to differences in the mix of testing services.

Operating Income. Our operating income increased by 70.7% to NT$4,848.6 million (US$157.4 million) in 1999 from NT$2,840.9 million in 1998, reflecting in part the effects of the acquisitions of ISE Labs, ASE Chung Li and ASE Korea, as well as increases in operating income at our existing facilities. After eliminating the results of ISE Labs, ASE Chung Li and ASE Korea for comparative purposes, our operating income increased by 31.6% in 1999 compared to 1998. Our adjusted operating margin increased to 15.0% compared to 13.7% for 1998, reflecting the higher adjusted gross margin and decreases in selling expense, partially offset by increases in research and development expense and other expense, all as a percentage of net revenues. Selling expense as a percentage of net revenues decreased primarily as a result of economies of scale realized from increased sales volumes at our existing facilities. Amortization of goodwill expense increased in 1999 compared to 1998 in absolute terms primarily as a result of the acquisition of ISE Labs and ASE Korea in 1999, but remained relatively unchanged as a percentage of net revenues.

Net Non-Operating Income. In 1999, our non-operating income increased significantly primarily as a result of an increase in capital gains recognized. These capital gains amounted to NT$5,544.2 million (US$180.0 million) and were mostly generated by the sales of ASE Test ordinary shares by our subsidiary J&R Holding Limited through a public offering of Taiwan Depositary Receipts and the sale of ASE Inc. common shares by our subsidiaries and affiliates in a private placement of GDSs. Most of the common shares underlying the GDSs were acquired by our subsidiaries between March 1996 and April 1998 as part of a share purchase program instituted in support of ROC government policies. A small amount was realized from open market sales of ASE Test Taiwan Depositary Receipts by our subsidiaries and affiliates.

##### Table of Contents

Net foreign exchange loss decreased in 1999 compared to 1998, reflecting the higher than usual losses incurred in 1998 attributable to Japanese yen-denominated liabilities created in the second half of 1998 to manage our foreign exchange exposure. Net interest expense increased in 1999 compared to 1998 primarily as a result of increased debt financing incurred for our acquisitions in 1999.

Amortization of goodwill expense in connection with the acquisition of shares of our affiliates increased in 1999 compared to 1998, primarily as a result of our purchase of 22.6% of the outstanding shares of Universal Scientific.

Net Income. Our net income for 1999 was NT$7,794.7 million (US$253.1 million), or NT$7,225.4 million after eliminating the results of ISE Labs, ASE Chung Li and ASE Korea, compared to NT$1,604.0 million for 1998. Our adjusted net income increased in 1999 compared to 1998 primarily as a result of the foregoing factors, partially offset by an increase in our adjusted effective tax rate to 3.2% in 1999 compared to a benefit of (7.6%) in 1998. Our net income for 1999, less capital gains recognized upon the sale of long-term investments, was NT$2,250.5 million (US$73.1 million), compared to NT$997.1 million for 1998.

Year Ended December 31, 1998 Compared to Year Ended December 31, 1997

Net Revenues. In 1998, packaging and testing revenues accounted for 81.2% and 15.1% of our net revenues, respectively, compared to 80.3% and 12.5%, respectively, for 1997. The increase in our net revenues for 1998 compared to 1997 resulted primarily from the depreciation of the NT dollar against the U.S. dollar in 1998 compared to 1997. Because the majority of our sales were denominated in U.S. dollars, the depreciation of the NT dollar resulted in an increase of our sales in NT dollar terms. The selling prices in U.S. dollar terms for our packaging and testing services significantly decreased in 1998 compared to 1997, primarily as a result of the intense price competition we faced from other independent packaging and testing companies. Many of these companies sharply lowered prices in 1998 in an attempt to maintain capacity utilization in their facilities in response to a downturn in the semiconductor industry during this period. The decrease in selling prices also reflected the general trend in the semiconductor industry of declining prices per input/ output lead on semiconductor devices. The adverse effect on the average realized selling price of our packaging products was partially offset by a change in our revenue mix as our BGA packages, which typically command higher selling prices, accounted for a greater portion or our packaging volume, and as we tested more complicated semiconductor devices.

Gross Profit. Our gross profit decreased by 0.7% to NT$5,294.3 million in 1998 from NT$5,329.7 million in 1997. Our gross margin decreased to 25.5% in 1998 compared to 27.9% for 1997 primarily as a result of increases in depreciation and factory supplies as well as an increase in provision for inventory obsolescence, partially offset by decreases in raw material costs, all as a percentage of net revenues. The increase in provision for inventory obsolescence was due primarily to a one-time increase in provision for inventory obsolescence of ASE Technologies. Depreciation increased and raw material costs decreased in 1998 compared to 1997 primarily as a result of a change in our overall revenue mix as testing services, which typically incur significant depreciation costs but involve no raw material, accounted for a greater portion of our net revenues. Depreciation also increased in 1998 as we commenced depreciating new wire bonders and testers placed into service in part as a result of the ramp-up of our BGA production capabilities. The new equipment was then not fully utilized as a result of the downturn in the semiconductor industry. Factory supplies, such as rinsing agents and shipping materials, increased in 1998 compared to 1997 primarily reflecting increases in our packaging volume of BGA packages. Our gross margin for packaging decreased to 21.9% in 1998 from 26.0% in 1997 primarily due to increases in raw material and depreciation and amortization costs as well as inventory obsolescence reserve, all as percentages of packaging sales. The inventory obsolescence reserve increase was due to a one-time additional provision for inventory

obsolescence of ASE Technologies. Our gross margin for testing in 1998 decreased to 47.4% from 48.2% in 1997 primarily due to an increase in depreciation and amortization as a percentage of net sales, partially offset by decreases in direct and indirect labor and other manufacturing costs as percentages of net sales.

Operating Income. Our operating income decreased by 19.3% to NT$2,840.9 million in 1998 from NT$3,521.4 million in 1997. Our operating margin decreased to 13.7% in 1998 compared to 18.4% for 1997, reflecting the lower gross margin and increases in amortization of goodwill expense, research and development expense and other expense, all as a percentage of net revenues. Amortization of goodwill expense increased in 1998 compared to 1997 primarily as a result of open market purchases of 2.1 million ASE Test ordinary shares as part of a market repurchase program carried out between December 1997 and March 1998. Other expense such as charitable donations, professional fees and facilities maintenance charges increased as a percentage of net revenues in 1998 compared to 1997. Research and development expense increased as a percentage of net revenues in 1998 compared to 1997 primarily as a result of increases in compensation expense for research and development personnel and in depreciation of testers and other equipment dedicated to research and development uses.

Net Non-Operating Income. Our net non-operating loss was NT$859.6 million in 1998, compared to a net income of NT$4,621.3 million in 1997, primarily as a result of a decrease in capital gains realized upon the sale of long-term investments and increases in net foreign exchange loss and net interest expense. Capital gains realized upon the sale of long-term investments decreased in 1998 compared to 1997, reflecting the higher than usual gains realized in 1997. The capital gains recognized in 1997, in an amount of NT$4,870.9 million, resulted primarily from the offering of ASE Test ordinary shares by J&R Holding in June 1997 and the offering of Taiwan Depositary Receipts representing ASE Test ordinary shares by J&R Holding in December 1997. Net foreign exchange loss increased in 1998 compared to 1997 primarily as a result of losses incurred in 1998 attributable to Japanese yen-denominated liabilities created in the second half of 1998 to manage our foreign exchange exposure. Net interest expense increased in 1998 compared to 1997 primarily as a result of interest payable on US$200 million aggregate principal amount of bonds convertible into common shares of ASE Inc. issued in November 1997.

Net Income. Our net income for 1998 was NT$1,604.0 million, compared to NT$7,403.5 million for 1997. Our net income decreased in 1998 compared to 1997 primarily as a result of the foregoing factors, partially offset by a decrease in our effective tax rate to a benefit of (7.6%) compared to 4.6% in 1997. Our net income for 1998, less capital gains recognized upon the sale of long-term investments, was NT$997.1 million, compared to NT$2,532.6 million for 1997.

Our net revenues have generally increased in each quarter of the six-quarter period, except for the first quarter of 2000. Our net revenues are generally lower in the first quarter of the year as compared to the fourth quarter of the preceding year, primarily due to the combined effects of holidays in the United States, Taiwan, Korea and Malaysia. Our net revenues increased significantly in the third and fourth quarters of 1999 compared to the first and second quarters of 1999. These increases in net revenues resulted in part from the revenues contributed by ASE Chung Li and ASE Korea which we acquired in July 1999 and in part as a result of increased volume and an upturn in the average realized selling prices for packaging and testing services resulting from an upturn in the semiconductor industry. Under ROC GAAP, the revenues contributed by ISE Labs, which we acquired on May 4, 1999, have been included in our consolidated net revenues as if we had acquired ISE Labs on January 1, 1999. After eliminating the results of ASE Chung Li and ASE Korea for comparative purposes, our net revenues increased by 11.5% to a total of NT$17,744.0 million in the first and second quarters of 2000 from NT$15,919.3 million in the third and fourth quarters of 1999.

Our gross margin has generally increased in the six-quarter period, except during the fourth quarter of 1999 and second quarter of 2000. The improvement in our gross margin is primarily the result of decreased raw material costs and depreciation expense, all as a percentage of net revenues. Raw material costs as a percentage of net revenues decreased primarily as a result of lower substrate costs. Depreciation expense decreased as a percentage of net revenues primarily as a result of increased capacity utilization at our packaging and testing facilities. Our gross margin decreased slightly to 30.8% in the second quarter of 2000 from 31.3% in the first quarter of 2000. This slight decrease resulted primarily from a change in our product mix as revenues derived from the testing of logic/mixed-signal semiconductors accounted for a smaller percentage of our net testing revenues. For the fourth quarter of 1999, our gross margin decreased slightly to 27.5% from 28.5% in the third quarter of 1999. This was primarily due to an increase in other manufacturing overhead costs as a percentage of net revenues.

Our quarterly operating results may vary significantly. Unfavorable changes may adversely affect our business, financial condition and results of operations.

Liquidity and Capital Resources

Our principal sources of cash are cash generated from operations and debt financing and, in certain years, proceeds from the sale of investments. Our primary uses of cash are to fund capital expenditures and working capital requirements related to our operations and expansion.

40

##### Table of Contents

Cash generated from our operations was NT$3,353.0 million (US$108.9 million) for the six months ended June 30, 2000, as compared to NT$2,324.7 million (US$75.5 million) for the six months ended June 30, 1999. The increase in cash generated from our operations in the six months ended June 30, 2000 reflected an increase in recurring net income (excluding extraordinary capital gains), partially offset by an increase in accounts receivable and short-term investments. The increase in recurring net income for the six months ended June 30, 2000 compared to the comparable period in 1999 resulted from an increase in the revenues and improvements in the operating margins of ASE Inc. and the operations of ASE Chung Li and ASE Korea (which were acquired in July 1999). Our cash generated from operations was NT$7,589.8 million (US$246.4 million) in 1999, NT$8,724.6 million in 1998 and NT$2,185.3 million in 1997. The decrease in our cash generated from operations in 1999 reflected a decrease in cash flow from trading securities and an increase in accounts receivable, partially-offset by increases in accounts payable, accrued expenses and other expenses. Our accounts receivable, inventory, accounts payable and accrued expense increased primarily as a result of the effect from our acquisition of ISE Labs, ASE Chung Li and ASE Korea, as well as from sales growth. Our accrued pension cost decreased primarily as a result of the severance payments made in connection with our acquisition of ASE Korea. For the six months ended June 30, 2000, our accounts receivable collection and average days inventory was 63 days and 29 days, respectively, compared to 58 days and 35 days, respectively, for the same period in 1999. Our accounts receivable collection improved to an average of 62 days in 1999 from an average of 68 days in 1998, while our average days inventory improved to 32 days in 1999 from 45 days in 1998. The increase in our cash generated from operations in 1998 reflected decreases in notes receivable, inventories and accounts receivable and an increase in accounts payable, partially offset by a decrease in accrued expenses and other expenses. Our accounts receivable, notes receivable and inventory decreased primarily as a result of the decreased sales in the fourth quarter of 1998 compared to the fourth quarter of 1997. Our accounts receivable collection improved to 68 days in 1998 from 72 days in 1997, while our average days inventory improved to an average of 45 days in 1998 from an average of 52 days in 1997.

As of June 30, 2000, we had negative working capital in the amount of NT$1,740.5 million (US$56.5 million) as a result of a decrease in cash of NT$5,569.0 million (US$180.8 million) from NT$11,809.1 million (US$383.4 million) to NT$6,240.0 million (US$202.6 million) and an increase in short-term borrowings. The cash and short-term borrowings were used to fund capital expenditures including the acquisition of additional packaging and testing equipment and the expansion of existing facilities and additional investments.

In connection with the expansion of our production capacity, we have incurred capital expenditures of NT$8,237.4 million, NT$7,447.7 million, NT$11,097.4 million (US$360.3 million) and NT$15,032.9 million (US$488.1 million) in 1997, 1998, 1999 and the six months ended June 30, 2000, respectively.

As of June 30, 2000, we had total short-term lines of credit of NT$19,677.0 million (US$638.9 million), of which NT$9,789.5 million (US$317.8 million) had been drawn. The interest rate for borrowings under these facilities ranged from 1.4% to 8.5% in 1999 and from 0.7% to 8.7% during the first half of 2000. See Note 11 of Notes to Consolidated Financial Statements. The majority of our short-term borrowings are denominated in NT dollars, with the remainder denominated principally in U.S. dollars.

As of June 30, 2000, our outstanding long-term bank loans, less current portion, were NT$10,116.4 million (US$328.5 million). Certain of our bank loans are secured by machinery and equipment. Our long-term bank loans bear interest at floating rates, which in 1999 ranged from 1.3% to 8.3% and from 5.2% to 9.5% during the first half of 2000. See Note 14 of Notes to Consolidated Financial Statements. Most of our long-term bank loans are denominated in NT dollars. In addition, as of June 30, 2000, we had outstanding convertible bonds denominated in U.S. dollars in an aggregate amount of NT$10,960.9 million (US$355.9 million), including

41

amounts outstanding under bonds guaranteed by ASE Test. See Note 13 of Notes to Consolidated Financial Statements.

We have budgeted total expenditures of NT$21,868.0 million (US$710.0 million) for 2000 in connection with the expansion of our production capacity, of which NT$15,032.9 million (US$488.1 million) had already been incurred as of June 30, 2000. As of December 31, 1999, we have long-term loan repayment obligations totaling NT$2,886.4 million (US$93.7 million) due in 2000. We also have NT$7,482.7 million (US$242.9 million) of short-term borrowings outstanding, part of which we would expect to renew. We expect to meet our working capital, capital expenditure, and debt repayment requirements in 2000 through cash from operations, the proceeds from this offering and the drawdown of outstanding credit lines. We have also raised capital at the subsidiary level to meet investment and capital requirements. In July 2000, ASE Test completed a US$276.0 million offering of ordinary shares. As of June 30, 2000, we had a cash position of NT$6,239.9 million (US$202.6 million), outstanding and unused short-term credit lines of NT$9,887.4 million (US$321.0 million) and unused long-term bank facilities of NT$2,827.7 million (US$91.8 million).

As of June 30, 2000, we had budgeted total capital expenditures of NT$22,792.0 million (US$740.0 million) for 2001. As of December 31, 1999, we have long-term loan repayment obligations totaling NT$3,419.6 million (US$111.0 million) in long-term loan repayments due in 2001. In addition, we have long-term loan repayment obligations totaling NT$7,991.6 million (US$259.5 million) in 2002, including our US$200,000,000 Zero Coupon Convertible Bonds Due 2002. We expect to meet our long-term working capital, capital expenditure and debt repayment requirements through cash from operations, the proceeds from this offering and further debt financing and capital raising if needed.

We have from time to time also liquidated long-term or short-term investments to provide cash for our operations and capital expenditures, including offerings of ASE Test ordinary shares, sometimes in the form of Taiwan Depositary Receipts, in 1997 and 1999 and the sale by our subsidiaries of ASE Inc. common shares in the form of GDSs in 1999.

From time to time, we evaluate possible investments, acquisitions or divestments and may, if a suitable opportunity arises, make an investment, acquisition or divestment. We currently have no commitments to make any material investment, acquisition or divestment. In July 2000 our shareholders approved a resolution which authorizes our board of directors to make investments in the People’s Republic of China. At such time as such an investment is permitted by the ROC investment law and policy and if suitable opportunities are available at that time, we intend to consider establishing a semiconductor packaging facility in the People’s Republic of China.

Taxation

Based on their respective statuses either as a company which is engaged in designated businesses in Taiwan or a “pioneer” company in Malaysia, the operating companies in the ASE Group were granted exemptions from ROC or Malaysia income taxes, as the case may be, generally for a period of four or five years, both at the initial stages of their operations and following subsequent capital increases with respect to income attributable to capital increases. These tax holidays resulted in tax savings for us of approximately NT$535.9 million, NT$508.8 million, NT$779.4 million (US$25.3 million) and NT$464.1 million (US$15.1 million) in 1997, 1998, 1999 and the six months ended June 30, 2000, respectively. Our current tax holiday under the ROC Statute for Upgrading of Industries expires at the end of 2000, but may be extended through cash injections from shareholders, such as rights offerings, the proceeds of which are used to purchase eligible machinery and equipment. We have not conducted a rights offering to our shareholders since 1996. The ROC Ministry of Finance announced recently that commencing 2000, this tax holiday may also be extended through the capitalization of retained earnings, that is, through the issuance of stock dividends. ASE Test Malaysia’s tax holiday in Malaysia expired on June 30, 1999 and ASE Test Malaysia has received approval to be a “pioneer high technology” company in Malaysia, which entitles us to a five-year tax holiday

42

##### Table of Contents

substantially similar to our previous tax holiday. We expect this tax holiday to commence retroactively on July 1, 1999. See Note 17 of Notes to Consolidated Financial Statements.

With facilities located in special export zones such as the Nantze Export Processing Zone in Taiwan and the Bayan Lepas Free Trade Zone in Malaysia, we enjoy exemptions from various import duties and commodity taxes on imported machinery, equipment, raw materials and components. Goods produced by companies located in these zones and exported or sold to others within the zones are exempt from otherwise applicable commodity or business taxes.

Our effective income tax rate was 4.6%, 0%, 5.1% and 12.4% in 1997, 1998, 1999 and the six months ended June 30, 2000, respectively. The effective tax rate was significantly lower in 1997, 1998 and 1999 because we had substantial capital gains income in those years that was not subject to ROC corporate tax.

Market Risk

Our exposure to financial market risks derives primarily from changes in interest rates and foreign exchange rates. To mitigate these risks, we utilize derivative financial instruments, the application of which is for hedging, and not for speculative, purposes.

Interest Rate Risks. Our exposure to interest rate risks relates primarily to our long-term floating rate debt, which is normally incurred to support our corporate activities, primarily capital expenditures. We currently do not enter into derivative transactions with regard to interest rates, but would consider engaging in currency interest rate swaps to lock in favorable currency and interest rate levels from time to time, if available, on terms considered attractive by us. No derivative contract was outstanding as of June 30, 2000.

Foreign Currency Risks. Our foreign currency exposures give rise to market risk associated with exchange rate movements against the NT dollar, our functional currency. Foreign currency denominated liabilities as of December 31, 1999 include U.S. dollar debt and Japanese yen debt. As of December 31, 1999, approximately 59.0% of our cash and accounts receivable were denominated in U.S. dollars, with a substantial portion of the remainder denominated in NT dollars. As of December 31, 1999, approximately 60.2% of our accounts payable and payable for fixed assets were denominated in currencies other than the NT dollar. To protect against reductions in value and the volatility of future cash flows caused by changes in foreign exchange rates, we may utilize currency forward contracts from time to time to reduce the impact of foreign currency fluctuations on our results of operations. Our policy is to account for these contracts on a mark-to-market rate basis, and the premiums are amortized on a straight-line basis over the life of the contract. As of December 31, 1999, there are no foreign currency forward exchange contracts outstanding. The following table provides information about our significant obligations that are sensitive to foreign currency exchange rate fluctuations. The principal amounts are presented by year of maturity and translated into U.S. dollars based on the current exchange rate.

Exchange Rate Fluctuations

Currently, the majority of our revenues from packaging and testing services are denominated in U.S. dollars, with a portion denominated in NT dollars, while our costs of revenues and operating expenses associated with packaging and testing services are incurred in several currencies, including U.S. dollars, NT dollars, Malaysian ringgit, Korean won, Philippine pesos, Singapore dollars and Hong Kong dollars. As a result, the depreciation of the NT dollar against the U.S. dollar tends to increase our net revenues in NT dollar terms. The slight increase in 1998 in our net revenues in NT dollar terms in 1998 was primarily as a result of this currency fluctuation effect. In 1997, 1998, 1999 and the six months ended June 30, 2000, the average exchange rate of the NT dollar to the U.S. dollar was 29.06, 33.54, 32.28 and 30.70, respectively. In addition, a substantial portion of our capital expenditures, primarily for the purchase of packaging and testing equipment, has been, and is expected to continue to be, denominated primarily in U.S. dollars with the remainder in Japanese yen. Fluctuations in exchange rates, primarily among the U.S. dollar, the NT dollar and the Japanese yen, will affect our costs and operating margins and could result in exchange losses and increased costs in NT dollar and other local currency terms. Despite hedging and mitigating techniques implemented by us, fluctuations in exchange rates have affected, and may continue to affect, our financial condition and results of operations. We recorded foreign exchange losses of NT$935.5 million in 1998 and NT$538.4 million (US$17.5 million) in 1999, due primarily to losses attributable to Japanese yen-denominated liabilities created by us in the second half of 1998 to manage our foreign exchange exposure. We have closed our position on these Japanese yen-denominated liabilities as of November 5, 1999.

US GAAP Reconciliation

Our financial statements are prepared in accordance with generally accepted accounting principles in the ROC, or ROC GAAP, which differ in material respects from generally accepted accounting principles in the United States, or US GAAP. The following table sets forth a comparison of our net income and shareholders’ equity in accordance with ROC GAAP and US GAAP for the periods indicated:

##### Table of Contents

Note 27 of Notes to Consolidated Financial Statements provides a description of the principal differences between ROC GAAP and US GAAP as they relate to us, and a reconciliation to US GAAP of select items, including net income and shareholders’ equity. Differences between ROC GAAP and US GAAP which have a material effect on our net income as reported under ROC GAAP relate to gain from the sale of treasury stock and compensation expense pertaining to bonuses to employees, directors and supervisors.

In 1998 and 1999, three of our consolidated subsidiaries sold an aggregate of 33.8 million ASE Inc. common shares in open market sales. See “— Results of Operations — Year Ended December 31, 1999 Compared to Year Ended December 31, 1998 — Net Non-Operating Income”. Under US GAAP, when a subsidiary holds its parent’s common shares as investments, the common shares are treated as treasury stock and is presented in the consolidated balance sheet as a deduction to shareholders’ equity. The capital gain or loss from the sale of treasury stock is added to or deducted from the balance of treasury stock. Under ROC GAAP, this treatment is not required and, as a result, the investment in ASE Inc. common shares by its subsidiaries is treated as long-term investment in the balance sheets and the capital gain or loss from the sale of treasury stock is recognized as income or loss. As a result of these transactions, we recognized under ROC GAAP capital gains on sale of investments of NT$1,388.5 million (US$45.1 million) in 1999 and NT$42.7 million in 1998. Under US GAAP, those investments in ASE Inc.’s common shares should be classified as treasury stock and the capital gain is not recognized as income but is deducted from treasury stock under capital surplus.

We paid employee bonuses in 1997, 1998 and 1999 in the form of common shares, and expect to pay all or a portion of employee bonuses in future periods in the form of common shares. In addition to bonuses paid as part of our regular employee bonus plan, we paid in 1998 a special stock bonus to our employees on account of our favorable results of operations for that year. The number of common shares distributed as part of employee bonuses is obtained by dividing the total nominal NT dollar amount of the bonus to be paid in the form of common shares by the par value of the common shares, or NT$10 per share, rather than their market value, which has generally been substantially higher than par value. Under ROC GAAP, the distribution of employee bonus shares is treated as an allocation from retained earnings, and we are not required to, and do not, charge the value of the employee bonus shares to income. Under US GAAP, however, we would be required to charge the market value of the employee bonus shares to employee compensation expense in the period to which they relate, correspondingly reduce our net income and income per common share calculated in accordance with US GAAP.

The amount and the form of the payment of this compensation is subject to approval by our board of directors and is only determinable at the first board meeting which is held after the issuance of our financial statements for the relevant year. Under US GAAP, the compensation expense is initially accrued at the nominal NT dollar amount of the aggregate bonus in the period to which it relates. For US GAAP purposes, the difference between the amount initially accrued and the market value of the common shares issued as payment of all or any part of the bonus is recorded as employee compensation expense in the period in which board approval is obtained, which normally occurs during the second quarter of each year. See Note 27 of Notes to Consolidated Financial Statements. Net income and income per common share amounts calculated in accordance with ROC GAAP and US GAAP differ accordingly. The amount of the adjustment for market price for the purpose of US GAAP reconciliation for the special stock bonus paid in 1997 was allocated over a period of three years commencing in the second quarter of 1998, reflecting the additional length of service which we require from employees who received special stock bonus.

Industry Background

General

Semiconductors are the basic building blocks used to create an increasing variety of electronic products and systems. Continuous improvements in semiconductor process and design technologies have led to smaller, more complex and more reliable devices at a lower cost per function. These improvements have resulted in significant performance and price benefits to manufacturers of electronic systems. As a result, semiconductor demand has grown substantially in our primary markets of personal computers and communications equipment, and has experienced increased growth in additional markets such as consumer electronic devices, automotive products, industrial automation and control systems. According to Dataquest, the global semiconductor market is expected to grow from US$169.1 billion in 1999 to US$319.8 billion in 2004, at a compound annual growth rate of 13.6%. Dataquest forecasts that the communications electronics market will be the fastest growing end use market for semiconductor applications over this period with an expected compound annual growth rate of 15.8%, followed by the automotive and consumer electronics markets with expected annual growth rates of 14.6% and 13.3%, respectively.

Outsourcing Trends in Semiconductor Manufacturing

Historically, semiconductor companies designed, manufactured, packaged and tested semiconductors primarily in their own facilities. In recent years, there has been a trend in the industry to outsource stages in the manufacturing process. Virtually every significant stage of the manufacturing process can be outsourced. Wafer foundry services and semiconductor packaging services are currently the largest segments of the independent semiconductor manufacturing services market. Most of the world’s major integrated device manufacturers use some independent manufacturing services to maintain a strategic mix of internal and external manufacturing capacity. We believe that many of these manufacturers are significantly reducing their investments in new semiconductor packaging and testing facilities and that several are contemplating the divestment of their in-house packaging and testing operations. Motorola’s sale to us of its packaging and testing operations in Taiwan and Korea in 1999 is an example of this divestment trend.

The availability of technologically advanced independent manufacturing services has also enabled the growth of “fabless” semiconductor companies that focus on semiconductor design and marketing and outsource their fabrication, packaging and testing requirements to independent companies. Dataquest estimates that “fabless” semiconductor companies’ share of the worldwide semiconductor market is expected to increase from 6.8% in 1998 to 9.8% by 2003. Similarly, the availability of technologically advanced independent manufacturing services has encouraged “systems companies”, which traditionally outsourced the manufacturing of

47

##### Table of Contents

semiconductor components used in the assembly of their systems products to integrated device manufacturers, increasingly to outsource to independent semiconductor manufacturing companies.

Electronic Trend Publications estimates that in 1999, 39.4% of the worldwide semiconductor packaging market by revenue and 20.5% by volume were accounted for by independent packaging service providers. It estimates the total size of the outsourced semiconductor packaging market in 1999 at US$7.2 billion. It further estimates that the total semiconductor packaging market will grow to US$35.7 billion in 2004, of which US$16.2 billion, or 45.5%, will be outsourced. It also forecasts that the compound annual growth rate for outsourced packaging between 1999 and 2004 will be 17.6% by revenue and 16.3% by volume with the highest growth attributed to BGA packages and chip scale packages. We estimate that the portion of the semiconductor testing market accounted for by independent testing service providers is smaller than that for packaging, and we expect outsourced testing to grow at a faster rate than outsourced packaging over the next few years.

We believe the outsourcing of semiconductor manufacturing services will increase in the future from current levels for many reasons, including the following:

Technological Sophistication and Significant Capital Expenditure. Semiconductor manufacturing processes have become highly complex, requiring substantial investment in specialized equipment and facilities and sophisticated engineering and manufacturing expertise. In addition, product life cycles have been shortening, magnifying the need to continuously upgrade or replace manufacturing equipment to accommodate new products. As a result, new investments in in-house packaging, testing and fabrication facilities are becoming less desirable to integrated device manufacturers not only because of the high investment costs as well as their inability to achieve sufficient economies of scales and utilization rates in order to be competitive with the independent service providers. Independent packaging, testing and foundry companies, on the other hand, are able to realize the benefits of specialization and achieve economies of scale by providing services to a large base of customers across a wide range of products. This enables them to reduce costs and shorten production cycles through high capacity utilization and process expertise. In the process, they are also able to focus on discrete stages of semiconductor manufacturing and deliver services of superior quality.

Focus on Core Competencies. As the cost of semiconductor manufacturing facilities increases, semiconductor companies are expected to further outsource their semiconductor manufacturing requirements in order to focus their resources on core competencies, such as semiconductor design and marketing.

Time-to-Market Pressure. The increasingly short product life cycle has accelerated time-to-market pressure for semiconductor companies, leading them to rely increasingly on outsourced suppliers as a key source for effective manufacturing solutions.

Growth of Fabless Semiconductor Companies and Outsourcing by Systems Companies. The substantial growth in the number of fabless semiconductor companies and systems companies that increasingly outsource their manufacturing requirements to independent companies will also continue to drive growth in the market for independent foundry, packaging and testing services.

The Semiconductor Industry in Taiwan and Southeast Asia

The semiconductor industry in Taiwan has been a leader in, and a major beneficiary of, the trend in outsourcing. Most semiconductor companies in Taiwan are engaged in only one or two stages of the semiconductor manufacturing process. As a result, Taiwan’s semiconductor industry tends to be more efficient as companies focus on particular stages of the semiconductor manufacturing process, develop economies of scale and maintain higher capacity utilization rates.

48

##### Table of Contents

In addition, because companies which provide the major stages of the production process are located near each other, Taiwanese semiconductor companies are attractive to customers who wish to outsource several parts of their semiconductor manufacturing. For instance, a semiconductor company in the United States could obtain foundry, packaging, testing, and drop shipment services from companies located near each other in Taiwan, and as a result, reduce cycle times and unit costs while streamline logistics. Moreover, a significant portion of the manufacturing capacity for the global electronics industry is located in Asia, further strengthening this competitive advantage. Through this specialization and a close network of customers and supplier partnerships, semiconductor companies in Taiwan can achieve superior economies of scale, flexibility, and customer responsiveness. Furthermore, Taiwan also has an educated labor pool and a large number of engineers suitable for sophisticated manufacturing industries such as semiconductors.

As a result of the growth of the global semiconductor market, the semiconductor industry in Taiwan has in recent years made significant capital expenditures to expand capacity and technological capabilities. The ROC government has also provided tax incentives, long-term loans at favorable rates and research and development support, both directly and indirectly through support of research institutes and universities. As a result of investments made in recent years, Taiwan has achieved substantial market share in the outsourced semiconductor manufacturing business. Furthermore, the growth of Taiwan’s electronics industry, particularly in personal computer design and manufacturing, has created substantial local demand for semiconductors.

Many of the factors that contributed to the growth of the semiconductor industry in Taiwan have also contributed to the recent development of the semiconductor industry in Southeast Asia. Access to expanding semiconductor foundry services in Singapore, convenient proximity to major downstream electronics manufacturing operations in Malaysia, Singapore and Thailand, government sponsored infrastructure support, tax incentives and pools of skilled engineers and labor at relatively low cost have all encouraged the development of back-end semiconductor service operations in Southeast Asia. The downstream electronics manufacturers in Southeast Asia have typically focused on products used in the communications, industrial and consumer electronics and personal computer peripheral sectors. The proximity to both semiconductor foundries and end users has influenced local and international semiconductor companies increasingly to obtain packaging, testing and drop shipment services from companies in Southeast Asia.

Overview of Semiconductor Manufacturing Process

The manufacturing of semiconductors is a complex process that requires increasingly sophisticated engineering and manufacturing expertise. The manufacturing process may be divided into the following stages from circuit design to shipment:

We are involved in all stages of the semiconductor manufacturing process except circuit design and wafer fabrication.

Process |  | Description
Circuit Design |  | The design of a semiconductor is developed by laying out circuit components and interconnections. A complex circuit may be designed with as many as 20 layers of patterns or more.
Front-End Engineering Test |  | Throughout and following the design process, prototype semiconductors undergo front-end engineering testing, which involves software development, electrical design validation, reliability and failure analysis.
Wafer Fabrication |  | Process begins with the generation of a photomask through the definition of the circuit design pattern on a photographic negative, known as a mask, by an electron beam or laser beam writer. These circuit patterns are transferred to the wafers using various advanced processes.
Wafer Probe |  | Each individual die is electrically tested, or probed, for defects. Dies that fail this test are marked to be discarded.

50

##### Table of Contents

Process |  | Description
Packaging |  | Packaging, also called assembly, is the processing of bare semiconductors into finished semiconductors and serves to protect the die and facilitate electrical connections and heat dissipation. The patterned silicon wafer received from our customers are diced by means of diamond saws into separate dies, also called chips. Each die is attached to a leadframe or a laminate (plastic or tape) substrate by epoxy resin. A leadframe is a miniature sheet of metal, generally made of copper and silver alloys, on which the pattern of input/output leads has been cut. On a laminate substrate, typically used in ball grid array packages, the leads take the shape of small bumps or balls. Leads on the lead frame or the substrate are connected by extremely fine gold wires to the input/output terminals on the chips, through the use of automated machines known as “wire bonders”. Each chip is then encapsulated, generally in a plastic casing molded from a molding compound, with only the leads protruding from the finished casing, either from the edges of the package as in the case of the leadframe packages, or in the form of small bumps on a surface of the package as in the case of ball grid array or other laminate packages.
Final Test |  | Final testing is conducted to ensure that the packaged semiconductor device meets performance specifications. Final testing involves using sophisticated testing equipment and customized software programs to electrically test a number of attributes of packaged semiconductors, including functionality, speed, predicted endurance and power consumption. The final testing of semiconductors is categorized by the functions of the semiconductors tested into logic/ mixed-signal final testing, and memory final testing. Memory final testing typically requires simpler test software but longer testing time per device tested.

Strategy

Our objective is to provide leading-edge semiconductor packaging and testing solutions which set industry standards and facilitate the industry trend to outsource semiconductor manufacturing requirements. The principal elements of our strategy are to:

Expand Strategically Our Production Capacity and Product Expertise

We plan to continue to expand strategically our production capacity and product expertise, both through internal growth and through acquisitions, to address the increasing demand for independent semiconductor packaging and testing services. We evaluate acquisition opportunities on the basis of access to new markets and technology, increased proximity to our existing and potential customers, the enhancement of our production capacity and economies of scale and our management resources.

In 1999, we acquired ISE Labs, an independent testing company with operations in California, Hong Kong and Singapore, as well as ASE Chung Li and ASE Korea, formerly the semiconductor packaging and testing operations of Motorola located in Chung Li, Taiwan and Paju, Korea. We acquired ISE Labs with a view to combining its front-end engineering testing capabilities with our final testing capabilities to provide our customers with complete

51

##### Table of Contents

semiconductor packaging and testing solutions. Through the acquisition of ASE Chung Li and ASE Korea, we gained access to specialized packaging and testing technologies with a focus on wireless communications and automotive end-products. As part of the acquisition, we also entered into service agreements for Motorola’s continuing business at the Taiwan and Korea facilities. Our acquisition of the Motorola operations will serve as a model for our future acquisitions of in-house packaging and testing facilities of integrated device manufacturers.

We believe that the success of the Motorola acquisition will encourage other integrated device manufacturers to divest their in-house operations to us and then retain us to satisfy the packaging and testing requirements formerly met by their in-house operations. We continue to evaluate acquisition opportunities and plan to make additional acquisitions in the future if suitable opportunities arise. Although our general strategy is to expand or invest in new packaging facilities through ASE Inc. and new testing facilities through ASE Test, we will continue to make these determinations on a case-by-case basis. For opportunities such as the former Motorola facilities in Taiwan and Korea with integrated packaging and testing operations, we may continue to divide our investments among group companies to reflect our estimates of the relative packaging and testing values at those facilities.

Enhance Our Technological, Processing and Materials Capabilities

We intend to continue our focus on developing advanced process and product technology in order to provide our customers with leading-edge solutions for their semiconductor packaging and testing requirements. Our expertise in packaging technology has enabled us to develop solutions such as fine-pitch bonding for leadframe packages, stacked die configuration for ball grid arrays and bump chip carrier packaging for communications applications.

We intend to enhance our expertise both upstream and downstream in the semiconductor manufacturing process in order to better serve our customers in our core services of packaging and testing. As product lives and production cycles shorten and packaging and testing technologies advance more rapidly, our customers increasingly value our ability, as a downstream service provider, to work with them as an integral and strategic partner in the upstream development of their products. Our acquisition of the front-end engineering testing capabilities of ISE Labs has enhanced greatly our capabilities to participate in the earlier stages of circuit design and the semiconductor manufacturing process. Our establishment of ASE Material for the production of interconnect materials such as leadframes and substrates has provided us with expertise in interconnect technology, which has become an increasingly critical part of the product development stage for our customers in terms of cost and production time.

The increasing miniaturization of semiconductors and the growing complexity of interconnect technology have led to the blurring of the traditional distinctions among assembly at different (that is, upstream and downstream) levels of integration: chip, module, board and systems. Our acquisition of a controlling interest in Universal Scientific has given us access to process and product technologies at the levels of module, board and systems assembly and test, which helps us to better anticipate industry trends and the needs of our end users, who are the end-clients of our customers.

| Strengthen and Develop Strategic Alliances with Providers of Complementary Manufacturing Services

We intend to strengthen existing and develop new strategic alliances with providers of other complementary semiconductor manufacturing services, such as foundries, as well as equipment vendors, raw material suppliers and technology research institutes, in order to offer our customers total semiconductor manufacturing solutions covering all stages of the manufacturing of their products from design to shipment.

52

##### Table of Contents

Since 1997, we have maintained a strategic alliance with TSMC, the world’s largest dedicated semiconductor foundry, which designates the ASE Group as the non-exclusive preferred provider of packaging and testing services for semiconductors manufactured by TSMC. Through our strategic alliance with and close geographic proximity to TSMC, we are able to offer our customers a total semiconductor manufacturing solution that includes access to foundry services in addition to our packaging, testing and direct shipment services.

We are also working with TSMC in developing the next generation of packaging product technology. We are currently co-developing with TSMC wafer bumping technology to implant directly onto the die input/output leads that will be connected to leads on laminate substrates without the use of wires. We are developing similar strategic relationships with other major foundries and providers of other complementary semiconductor manufacturing services in Taiwan and Southeast Asia with which we already have close business relationships.

Better Serve Our Customers Through Our Diversified Geographic Presence

We are located in close geographic proximity to the facilities of our customers and providers of complementary semiconductor manufacturing services, including foundries, in key centers for outsourced semiconductor manufacturing. This proximity enables us to work closely with our customers, and other service providers, enhances our responsiveness to the requirements of our customers and shortens production cycles by reducing the time required to ship semiconductors from one stage of the manufacturing process to the next. We maintain packaging or testing facilities in the following strategic locations in order to better serve our customers:

| • | Taiwan — currently the largest center for outsourced semiconductor manufacturing in Asia with its high concentration of foundries, customers and end users;
| • | Malaysia and Singapore — the emerging center for outsourced semiconductor manufacturing in Southeast Asia with a concentration of integrated device manufacturers;
| • | Korea — a center for the manufacturing of memory devices and semiconductors for communications applications with a concentration of integrated device manufacturers specializing in these products; and
| • | Silicon Valley in California — the pre-eminent center for semiconductor design with a concentration of fabless customers.

Achieve Economies of Scale From Our Expanded Production Capacity

We are re-mapping our organizational management structure to better integrate our operations in areas such as research and development, purchasing, manufacturing processes and materials, marketing and sales and information technology systems across our various facilities. Operations that were formerly conducted more or less independently at our individual facilities will be coordinated more closely and come under more centralized management. The pooling of resources in a matrix organizational management structure will enable all of our facilities to realize the benefits of the expanded scale of our aggregate production, such as reduced cost of raw materials and equipment purchased through collective bargaining with various raw materials suppliers and equipment vendors, a broader range of solutions and services, enhanced geographic coverage and increased flexibility in capacity allocation.

We are developing procedures which will facilitate the sharing of the different expertise in process technology and practical know-how among our different facilities. The sharing of best practices will significantly reduce the amount of time required by our facilities to install and operate a new production line for the packaging or testing of new product types for which one of our facilities may have greater expertise or know-how.

Principal Products and Services

We offer a broad range of semiconductor packaging products and testing services. Our packaging products are based primarily on surface mount technology, also known as SMT, and employ either leadframes or laminate substrates as interconnect materials. Our packaging products are used in a wide range of end use markets, including for communications, consumer, industrial, automotive, personal computer and other applications. Our testing services include front-end engineering testing, which is performed during and following the initial circuit design stage of the semiconductor manufacturing process; wafer probe; final testing and other related semiconductor testing services. We offer our customers the integrated packaging, testing and direct shipment of semiconductors to end users designated by our customers. In 1999, our packaging revenues accounted for 75.2% of our net revenues and our testing revenues accounted for 23.9% of our net revenues. For the six months ended June 30, 2000, our packaging revenues accounted for 75.1% of our net revenues and our testing revenues accounted for 24.5% of our net revenues.

Packaging

We offer a broad range of semiconductor packages using primarily the SMT technology, including:

| • | plastic leaded chip carrier packages, also called PLCC;
| • | quad flat packages, also called QFP;
| • | thin quad flat packages, also called TQFP;
| • | small outline plastic packages, also called SOP;
| • | small outline plastic J-bend packages, also called SOJ;
| • | thin small outline plastic packages, also called TSOP; and
| • | ball grid array, also called BGA.

Within our packaging product portfolio, we focus on the assembly of semiconductor packages for which there is expected to be strong demand, including high pin-count SMT packages, such as QFPs and TQFPs, both of which are based on leadframes, and SMT packages based on laminate substrates, such as BGAs.

In SMT, the leads on semiconductors and other electronic components are soldered to the surface of the printed circuit board rather than inserted into holes, as compared with the older pin-through-hole technology, also called PTH. Our principal PTH product is plastic dual in-line packages, also called PDIP. SMT can accommodate a substantially higher number of leads than PTH, enabling the board to interconnect a greater number of integrated circuits. This in turn allows a reduction in the number of integrated circuits used and, together with tighter component spacing, permits a reduction in the dimensions of the printed circuit board. Because of their high lead counts, most very large scale integrated circuits are configured for surface mounting. Additionally, SMT allows components to be placed on both sides of the board, enabling even greater density. The substantially finer lead-to-lead spacing, or pitch, in SMT products requires a packaging process which is more exacting than the packaging process for PTH products.

Leadframe-based products are the traditional SMT packages which are packaged by connecting the die, using wire bonders, to the leadframe with gold wire leads. As the packaging technology improves, the number of leads per package increases. In the process, packages have

evolved from the lower pin-count plastic leaded chip carriers to quad flat packages. The following table sets forth our principal leadframe-based packaging products.

|  | Number |  |
Package Format |  | of Leads |  | Applications

Laminate-Based BGA Products

An important subset of SMT packages are BGA packages. In BGA technology, the leads used to connect the semiconductor device to the circuit board take the shape of small bumps or balls which are attached to the bottom of the package surface, as opposed to traditional leadframe technology which has leads protruding from the edges like pins. These small bumps or balls are typically distributed evenly across the bottom surface of the package, allowing greater distance between individual leads. BGA packages typically feature higher pin-count, smaller package sizes, greater reliability, superior electrical signal transmission, and better heat dissipation than traditional leadframe-based packaging technology. BGA packages are generally used in applications where size, density and performance are important considerations, such as cellular handsets and high pin-count graphic chipsets. We also have capabilities in stacked-die BGA, which assembles multiple dies into a single package. As an extension to stacked-die BGA, we also assemble systems-in-a-package products, which are integrated combinations of logic chips assembled into the same package. We believe that we are among the leaders in these packaging technologies.

The industry demand for BGA packages has grown significantly in recent years. In light of the continuing demand for packages with higher pin-counts and smaller sizes, we commenced in July 2000 volume production in flip chip packages. For interconnections within the package, flip chip BGA technology replaces wire bonding with wafer bumping, which requires tiny solder balls, instead of wires, to be placed on top of dies for connection to substrates. As compared with more traditional packages which allow input/output connection only on the boundaries of the dies, flip chip packages significantly enhance the input/output flow by allowing input/output connection over the entire surface of the dies.

In addition, we are currently developing land grid array, or LGA, a type of BGA package. Because LGA packages do not employ solder balls, it is a lead-free packaging solution. LGA packages are designed for semiconductors requiring a small, thin and light package. We expect

56

##### Table of Contents

LGA packages to be used in end use applications such as portable personal computers, personal digital assistants and cellular phones.

The following table sets forth our principal BGA packaging products.

Testing

We provide a complete range of semiconductor testing services, including front-end engineering testing, wafer probing, final testing of logic/mixed-signal and memory semiconductors and other test-related services.

The testing of semiconductors requires technical expertise and knowledge of the specific applications and functions of the semiconductors tested. We believe that our testing services employ technology and expertise which are among the most advanced in the semiconductor industry. In addition to maintaining different types of testing equipment, which enables us to test a variety of semiconductor functions, we work closely with our customers to design effective testing and conversion programs on multiple equipment platforms for particular semiconductors.

In recent years, complex, high-performance logic/mixed-signal semiconductors have accounted for an increasing portion of our overall net testing revenues. As the testing of complex, high-performance semiconductors requires a large number of functions to be tested using more advanced testing equipment, these products generate higher revenues per unit of testing time, as measured in central processing unit, or CPU, seconds.

Front-End Engineering Testing. We provide front-end engineering testing services, including software program development, electrical design validation, and reliability and failure analysis.

| • | Software Program Development. Design and test engineers develop a customized software program and related hardware to test the semiconductor on advanced testing equipment. A customized software program is required to test the conformity of each particular semiconductor type to its unique functionality and specification.
| • | Electrical Design Validation. A prototype of the designed semiconductor is submitted to electrical tests using advanced test equipment, customized software programs and related hardware. These tests assess whether the prototype semiconductor complies with a variety of different operating specifications, including functionality, frequency, voltage, current, timing and temperature range.
| • | Reliability Analysis. Reliability analysis is designed to assess the long-term reliability of the semiconductor and its suitability of use for intended applications. Reliability testing can include “burn-in” services, which electrically stress a device, usually at high temperature and voltage, for a period of time long enough to cause the failure of marginal devices.
| • | Failure Analysis. In the event that the prototype semiconductor does not function to specifications during either the electrical design validation or reliability testing processes, it is typically subjected to failure analysis to determine why it did not perform as anticipated. As part of this analysis, the prototype semiconductor may be subjected to a variety of analyses, including electron beam probing and electrical testing.

Wafer Probing. Wafer probing is the step immediately before the packaging of semiconductors and involves visual inspection and electrical testing of the processed wafer for defects to ensure that it meets our customers’ specifications. Wafer probing services require expertise and testing equipment similar to that used in logic/mixed-signal testing, and several of our testers are also used for wafer probing.

Logic/Mixed-Signal Final Testing. We conduct final tests of a wide variety of logic/mixed-signal semiconductors, with the number of leads ranging in the single digits to several hundreds and operating frequencies of up to 400 MHz, which is at the high end of the range for the industry. The products we test include semiconductors used for networking and wireless communications, graphics and disk controllers for home entertainment and personal computer applications, as well as a variety of application specific integrated circuits, or ASICs, for various specialized applications.

Memory Final Testing. We provide final testing services for a variety of memory products, such as static random access memory, or SRAM, dynamic random access memory, or DRAM, and single-bit electronical programmable read-only memory semiconductors.

Other Test-Related Services. We provide a broad range of additional test-related services, including:

| • | Burn-in Testing. Burn-in is the process of electrically stressing a device, usually at high temperature and voltage, for a period of time to simulate the continuous use of the device to determine whether this use would cause the failure of marginal devices.
| • | Dry Pack. Process which involves heating semiconductors in order to remove moisture before packaging and shipping to customers.
| • | Tape and Reel. Process which involves transferring semiconductors from a tray or tube into a tape-like carrier for shipment to customers.

Drop Shipment Services. We offer drop shipment services for shipment of semiconductors directly to end users designated by our customers. Drop shipment services are provided mostly in conjunction with logic/mixed-signal testing. We provide drop shipment services to a majority of our testing customers. A substantial portion of our customers at each of our facilities have qualified these facilities for drop shipment services. Since drop shipment eliminates the additional step of inspection by the customer before shipment to the end user, quality of service is a key consideration. We believe that our ability to successfully execute our full range of services, including drop shipment services, is an important factor in maintaining existing customers as well as attracting new customers.

The following table sets forth, for the periods indicated, the percentage of our testing revenues accounted for by each type of testing service.

Expansion

We are expanding our facilities in Taiwan and Malaysia to meet the growing demand for our products and services from existing and new customers.

We commenced an expansion project in Chung Li, Taiwan in December 1999. The first phase of the project is the construction of a building with aggregate floor space of approximately 800,000 square feet to accommodate the expected growth of our operations in Chung Li. Construction is expected to be completed in the fourth quarter of 2000. The total value of the first phase of the project, including land and the completed building, is estimated to be NT$2.0 billion. Hung Ching, which is the developer of the project, will bear all costs relating to the development. The new building is expected to house ASE Chung Li’s testing operations as well as part of the operations of other ASE Group companies. See “Certain Transactions”.

Furthermore, we commenced an expansion project in Kaohsiung, Taiwan in the second quarter of 2000. The first phase of the project is the construction of a building with aggregate floor space of 1.1 million square feet to accommodate the expected growth of our operations in Kaohsiung. Construction is expected to be completed in the second quarter of 2001 at a cost of NT$2.0 billion. The new building is expected to house part of ASE Inc.’s packaging operations in Kaohsiung, part of ASE Test Taiwan’s testing operations and part of ASE Material’s substrate manufacturing operations. A portion of the net proceeds of this offering will be applied to finance the cost of constructing the new building.

We also commenced an expansion project in Penang, Malaysia in the fourth quarter of 1999. The first phase of the project is the construction of a building with floor space of approximately 100,000 square feet which is expected to be completed in the third quarter of 2000. The construction of an additional 100,000 square feet is expected to be completed in the fourth quarter of 2000. The aggregate cost of the project is expected to be US$10.8 million.

Because we are operating at a relatively high capacity utilization rate, we plan to purchase an additional 1,488 wire bonders and 259 testers in 2000. We estimate the aggregate cost of this purchase will be approximately US$650.0 million. A portion of the net proceeds of this offering will be applied to finance these purchases.

Other Members of the ASE Group

Consolidated Subsidiaries

ASE Test. ASE Test, which is a Singapore company, is one of the largest independent testing companies in the world, providing a complete range of semiconductor testing services to leading international semiconductor companies. In addition, ASE Test provides a broad range of leadframe and laminate-based semiconductor packaging services. ASE Test has testing operations in Taiwan, the United States, Hong Kong and Singapore, and also maintains testing and packaging operations in Malaysia.

ASE Test was incorporated in 1996 and its ordinary shares have been quoted for trading on the Nasdaq National Market since June 1996 under the symbol “ASTSF”. Following the completion of ASE Test’s follow-on offering of ordinary shares on July 19, 2000, we held approximately 51.3% of the outstanding shares of ASE Test. We also hold the equivalent of another 2.5% of the company through options created on ASE Test’s convertible notes issued in 1999. ASE Test is a holding company whose significant assets are its ownership interests in the following operating companies:

| • | 99.98% of ASE Test Taiwan;
| • | 100% of ASE Test Malaysia;
| • | 75.3% of ISE Labs;

63

##### Table of Contents

| • | 30% of ASE Chung Li (the remaining 70% of which is owned by ASE Inc.); and
| • | 30% of ASE Korea (the remaining 70% of which is owned by ASE Inc.).

In 1999, ASE Test recorded net revenues of US$298.7 million, operating income of US$67.2 million and net income of US$62.2 million. For the six months ended June 30, 2000, ASE Test recorded net revenues of US$194.8 million, operating income of US$52.7 million and net income of US$50.8 million. We currently intend to maintain a majority ownership interest in ASE Test. We continue to evaluate acquisition opportunities and plan to make additional acquisitions in the future if suitable opportunities arise. Although our general strategy is to expand or invest in new packaging facilities through ASE Inc. and new testing facilities through ASE Test, we will make these determinations on a case-by-case basis. For opportunities such as the former Motorola facilities in Chung Li and Korea with integrated packaging and testing operations, we may continue to divide our investments among group companies to reflect our estimates of the relative packaging and testing values at those facilities.

ASE Material. ASE Material, which is a ROC company, manufactures leadframes and other substrates used in the packaging of semiconductors. ASE Material currently supplies our packaging facilities in Kaohsiung with a portion of our leadframe and substrate requirements. See “— Raw Materials and Suppliers — Packaging”. As of June 30, 2000, we held 47.7% of the outstanding shares of ASE Material, comprising 37.7% held by ASE Inc. and 10.0% held by ASE Test Taiwan. The supervisor and two of the five directors of ASE Material are representatives of ASE Inc., one director is a representative of ASE Test Taiwan and the remaining two directors of ASE Material are Jason C.S. Chang, our Chairman, and Richard H.P. Chang, our Vice Chairman and Chief Executive Officer, serving in their individual capacities. Before October 1999, we held a majority equity interest in ASE Material. We plan to increase our current equity interest in ASE Material so as to regain a majority ownership interest before December 31, 2000.

We believe that interconnect technology will play an increasingly important role in semiconductor packaging as interconnect materials, such as leadframes and substrates, account for a growing portion of the cost of a semiconductor package. In anticipation of this trend, we established ASE Material in December 1997 for the purpose of developing, producing and selling leadframes and advanced substrates. In 1999 and the six months ended June 30, 2000, ASE Material supplied interconnect materials that accounted for approximately 8.0% and 7.5%, respectively, of our consolidated raw material costs. Substantially all of these materials were leadframes. We expect that by the end of 2000, ASE Material will supply approximately a third of the substrate requirements at our packaging facilities in Kaohsiung. We expect to continue making investments in ASE Material in order to further develop our in-house interconnect technology.

ASE Material’s facilities are located in the Nantze Export Processing Zone near our packaging and testing facilities in Kaohsiung, Taiwan. ASE Material plans to expand its production capacity with new facilities to be located near our packaging and testing facilities in Kaohsiung and Chung Li, Taiwan. In 1999, ASE Material recorded revenues of NT$790.5 million (US$25.7 million), operating loss of NT$88.9 million (US$2.9 million) and net income of NT$0.8 million (US$0.03 million). For the six months ended June 30, 2000, ASE Material recorded revenues of NT$576.4 million (US$18.7 million), operating loss of NT$153.2 million (US$4.9 million) and net loss of NT$165.8 million (US$5.4 million). Substantially all of ASE Material’s sales are to other ASE Group companies, and accordingly, substantially all of its sales and net income are eliminated by ASE Inc. in preparing our consolidated financial statements.

ASE Technologies. ASE Technologies, Inc., a ROC company, designs and assembles notebook computers, set-top boxes and liquid crystal display monitors, and assembles board and sub-systems. As of December 31, 1999, we held 75.0% of the outstanding shares of ASE Technologies.

Our five largest customers together accounted for approximately 32.3%, 34.3%, 40.0% and 49.7% of our sales in 1997, 1998, 1999 and the six months ended June 30, 2000, respectively. Other than Motorola, Inc. in 1999, no customer accounted for more than 10.0% of our net revenues in 1997, 1998 or 1999. For the six months ended June 30, 2000, no customer other than Motorola and VIA Technologies, Inc. accounted for more than 10% of our net revenues. In connection with our acquisition in July 1999 of Motorola’s in-house packaging and testing operations in Chung Li and Korea, we entered into manufacturing services agreements for Motorola’s continuing business at the Chung Li and Korea facilities. As a result, Motorola accounted for approximately 16.0% of our 1999 net revenues and 25.6% of our first half 2000 revenues. There has been significant variation in the composition of our largest five customers over time and, as a result, we have been less dependent on any particular customer over time. We package and test for our customers a wide range of products with end use applications in the personal computers, consumer, industrial and automotive, and communications sectors.

In 1999 and the six months ended June 30, 2000, approximately 90.0% and 73.3%, respectively, of the testing revenues of ASE Test Taiwan and 81.0% and 75.7%, respectively, of the testing revenues of ASE Test Malaysia was accounted for by the testing of semiconductors packaged at our packaging facilities in Kaohsiung and Malaysia, respectively. The balance represented testing revenues from customers who delivered packaged semiconductors directly to ASE Test Taiwan or ASE Test Malaysia for testing. In 1999 and the six months ended June 30, 2000, approximately 43.0% and 26.1%, respectively, of our packaging revenues in Kaohsiung and 62.0% and 65.2%, respectively, of our packaging revenues in Malaysia was accounted for by the packaging of semiconductors which were subsequently tested at ASE Test Taiwan and ASE Test Malaysia, respectively. We expect that more customers of our packaging facilities in Kaohsiung and Malaysia will begin to contract for our packaging and testing services on a turnkey basis.

Qualification and Correlation by Customers

Customers generally require that our facilities undergo a stringent “qualification” process during which the customer evaluates our operations and production processes, including engineering, delivery control and testing capabilities. The qualification process typically takes up to eight weeks, but can take longer depending on the requirements of the customer. In the case of our testing operations, after we have been qualified by a customer and before the customer delivers semiconductors to us for testing in volume, a process known as “correlation” is undertaken. During the correlation process, the customer provides us with sample

68

##### Table of Contents

semiconductors to be tested and either provides us with the test program or requests that we develop a conversion program. In some cases, the customer also provides us with a data log of results of any testing of the semiconductor which the customer may have conducted previously. The correlation process typically takes up to two weeks, but can take longer depending on the requirements of the customer.

Pricing

We price our packaging services primarily on a cost-plus basis and, to a lesser extent, with reference to market prices. Prices are confirmed at the time firm orders are received from customers, which is typically four to eight weeks before delivery.

We price our testing services primarily on the basis of the amount of time, measured in CPU seconds, taken by the automated testing equipment to execute the test programs specific to the products being tested as well as the cost of the equipment.

Raw Materials and Suppliers

Packaging

The principal raw materials used in our packaging processes are interconnect materials such as leadframes and substrates, gold wire and molding compound. Interconnect materials, such as leadframes and substrates, gold wire and molding compound represented approximately 54.6%, 21.5% and 11.4%, respectively, of our total cost of packaging materials in 1999, and approximately 56.8%, 19.8% and 11.1%, respectively, of our total cost of packaging materials for the six months ended June 30, 2000.

The silicon die, which is the functional unit of the semiconductor to be packaged, is supplied in the form of silicon wafers. Each silicon wafer contains a number of identical dies. We generally receive the wafers from the customer for which the semiconductor is being packaged. Consequently, we generally do not incur inventory costs relating to the silicon wafers used in our packaging process.

We do not maintain large inventories of leadframes, substrates, gold wire or molding compound, but generally maintain sufficient stock of each principal raw material for approximately one month’s production based on blanket orders and rolling forecasts of near-term requirements received from customers. In addition, several of our principal suppliers dedicate portions of their inventories, typically in amounts equal to the average monthly amounts supplied to us, as reserves to meet our production requirements. However, shortages in the supply of materials experienced by the semiconductor industry have in the past resulted in occasional price adjustments and delivery delays. For example, in 1997 and 1998, the industry experienced a shortage in the supply of advanced substrates used in BGA packages, which is currently available only from a limited number of suppliers located primarily in Japan. In these instances, we generally negotiate an extension of the delivery date from our customers.

We believe that interconnect technology will play an increasingly important role in semiconductor packaging as interconnect materials such as leadframes and substrates account for a growing portion of the cost of a semiconductor package. In anticipation of this trend, we established ASE Material in December 1997 for the purpose of developing, producing and selling leadframes and advanced substrates. In 1999 and the six months ended June 30, 2000, ASE Material supplied interconnect materials that accounted for approximately 8.0% and 7.5%, respectively, of our consolidated raw material costs. Substantially all of these materials were leadframes. We expect that by the end of 2000, ASE Material will supply approximately a third of the substrate requirements at our packaging facilities in Kaohsiung. We expect to continue making investments in ASE Material in order to further develop our in-house interconnect technology.

Testing

Apart from packaged semiconductors, no other raw materials are needed for the functional and burn-in testing of semiconductors. For the majority of our testing equipment, we often base our purchases on prior discussions with our customers about their forecast requirements. The balance consists of testing equipment on consignment from customers and which are dedicated exclusively to the testing of these customers’ specific products.

Equipment

Packaging

The most important equipment used in the semiconductor packaging process is the wire bonder. The number of wire bonders at a given facility is commonly used as a measure of the packaging capacity of the facility. The wire bonders connect the input/output terminals on the silicon die using extremely fine gold wire to leads on leadframes or substrates. Typically, wire bonders may be used, with minor modifications, for the packaging of different products. We purchase wire bonders principally from Kulicke & Soffa Industries Inc. and Shinkawa Limited of Japan. We currently operate an aggregate of 3,636 wire bonders, 20 of which are consigned by customers. In addition to wire bonders, we maintain a variety of other types of packaging equipment, such as wafer grind, wafer mount, wafer saw, die bonders, automated molding machines, laser markers, solder plat, pad printers, dejunkers, trimmers, formers, substrate saw and scanners.

Testing

Testing equipment is the most important and most capital intensive component of the testing process. We generally seek to purchase testers from different suppliers with similar functionality and the ability to test a variety of different semiconductors. We purchase testing equipment from major international manufacturers, including Credence Systems Corporation, Teradyne, Inc., Hewlett-Packard Asia Pacific Limited, Schlumberger Technologies, Advantest Corporation, Electroglas, Inc. and Megatest Corporation. Upon acquisition of new testing equipment, we install, configure, calibrate, perform burn-in diagnostic tests on and establish parameters for the testing equipment based on the anticipated requirements of existing and potential customers and considerations relating to market trends. We currently operate an aggregate of 871 testers, 121 of which are consigned by customers. In addition to testers, we maintain a variety of other types of testing equipment, such as automated handlers and probers (with special handlers for wafer probing), scanners, re-formers and personal computer workstations for use in software development. Each tester is attached to one or two handlers or probers, which transport individual dies to the tester for testing or probing.

In general, particular semiconductors can be tested on only a limited number of specially designed testers. As part of the qualification process, customers will specify the machines on which their semiconductors may be tested, and we often develop test program conversion tools that enable us to test semiconductors on multiple equipment platforms. This portability between testers enables us to allocate semiconductors tested across our available test capabilities and thereby improve capacity utilization rates. In cases where a customer requires the testing of a semiconductor product that is not yet fully developed, the customer may provide personal computer workstations to us to test specific functions. In cases where a customer has specified testing equipment that was not widely applicable to other products which we test, we have required the customer to furnish the equipment on a consignment basis.

Equipment Supply

As part of our expansion program, we plan to purchase approximately 1,488 new wire bonders and approximately 259 new testers in 2000. In particular, a majority of the testers we

70

##### Table of Contents

plan to purchase in 2000 will be Teradyne Catalyst, Credence Quartet, Hewlett-Packard HP93000/HP94000 testers, which are known in the industry as advanced testers. We will continue to place orders for and acquire additional packaging and testing equipment in future periods to the extent market conditions and demand for our services, cash generated from operations, the availability of financing and other factors make it desirable to do so. However, some of this equipment and related spare parts have been in short supply in recent years, and there is currently significant global demand for such equipment and related spare parts. Moreover, this equipment is only available from a limited number of vendors or is manufactured in relatively limited quantities, and may have lead times from order to delivery in excess of six months. We work closely with our vendors to evaluate new equipment and have long-term blanket orders and rolling forecasts in place. These orders are confirmed by us approximately three to six months before our desired delivery date in order to shorten the effective lead time necessary for the delivery of new equipment.

The unavailability of new wire bonders or testers or the failure of these equipment, or other equipment acquired by us, to operate in accordance with our specifications or requirements, or delays in the delivery of these equipment, could delay implementation of our expansion plans and could materially and adversely affect our financial condition or results of operation.

Research and Development

Packaging

We centralize our research and development efforts in packaging technology in our Kaohsiung facilities. After initial phases of development, we conduct pilot runs in one of our facilities before the new techniques or technologies are implemented commercially at other sites. Facilities with special product expertise, such as ASE Korea, also conduct research and development of these specialized products and technologies at their sites. One of the areas of emphasis for our research and development efforts is improving the efficiency and technology of our packaging processes. We expect these efforts to continue. We are now also putting significant research and development efforts into the development and adoption of new technology. We work closely with the manufacturers of our packaging equipment, including Kulicke & Soffa Industries Inc., a United States supplier of substantially all of our new wire bonders, in designing and modifying the equipment used in our production process. We also work closely with our customers to develop new product and process technology.

A significant portion of our research and development efforts is also focused on the development of advanced substrate production technology for BGA packaging through ASE Material. Substrate is the principal raw material for BGA packages. Development and production of advanced substrates involves complex technology and, as a result, high quality substrates are currently available only from a limited number of suppliers, located primarily in Japan. We believe that the successful development of substrate production capability by ASE Material will, among other things, help ensure a stable and cost-effective supply of substrates for our BGA packaging operations and to help shorten production time. We expect that by the end of 2000, ASE Material will supply approximately a third of the substrate requirements at our packaging facilities in Kaohsiung.

We have also entered into various non-exclusive technology license agreements with licensors including Tessera Inc., Fujitsu Limited, Flip Chip Technologies and Motorola, Inc. The technology we license from these companies includes solder bumping, redistribution, assembly and other technologies used in the production of package types such as bump chip carrier, flip chip packages and micro BGA. We are also working with TSMC in developing the next generation of packaging product technology. The license agreement with Tessera will not expire until the expiration of the Tessera patents licensed by the agreement. The license agreements with Fujitsu, Flip Chip, and Motorola will expire on April 13, 2003, March 1, 2009, and

71

##### Table of Contents

December 31, 2002, respectively. We hold no material patents. We are currently co-developing with TSMC wafer bumping technology to implant directly onto the die input/ output leads that will be connected to leads on laminate substrates without the use of wires.

Testing

Our research and development efforts in the area of testing have focused primarily on improving the efficiency and technology of our testing processes. Our current projects include developing software for parallel testing of logic semiconductors, rapid automatic generation and cross-platform conversion of test programs to test logic/ mixed-signal semiconductors, automatic code generation for converting and writing testing programs, testing new products using existing machines and providing customers remote access to monitor test results. We are also continuing the development of interface designs to provide for high-frequency testing by minimizing electrical noise. We work closely with our customers in designing and modifying testing software and with equipment vendors to increase the efficiency and reliability of testing equipment. Our research and development operations also include a mechanical engineering group, which currently designs handler kits for semiconductors testing and wafer probing, as well as software to optimize capacity utilization.

For 1997, 1998, 1999 and the six months ended June 30, 2000, our research and development expenditures totaled approximately NT$372.9 million, NT$453.6 million, NT$714.3 million (US$23.2 million) and NT$534.7 million (US$17.4 million), respectively. These expenditures represented approximately 2.0%, 2.2%, 2.2% and 2.3% of net revenues in 1997, 1998, 1999 and the six months ended June 30, 2000, respectively. We have historically expensed all research and development costs as incurred and none is currently capitalized. As of June 30, 2000, we employed 936 employees in research and development.

Quality Control

We believe that our advanced process technology and reputation for high quality and reliable services have been important factors in attracting and retaining leading international semiconductor companies as customers for our packaging and testing services. We have maintained an average packaging yield rate of 99.8% or greater in each of the last three years. We maintain a quality control staff at each of our facilities. Our quality control staff typically includes engineers, technicians and other employees who monitor packaging and testing processes in order to ensure high quality. Our quality assurance systems impose strict process controls, statistical in-line monitors, supplier control, data review and management, quality controls and corrective action systems. Our quality control employees staff quality control stations along production lines, monitor clean room environment and follow up on quality through outgoing product inspection and interaction with customer service staff. We have established quality control systems which are designed to ensure high quality service to customers, high product and testing reliability and high production yields at our facilities. In addition, our packaging and testing facilities have been qualified by all of our major customers after satisfying stringent quality standards prescribed by these customers.

Our packaging and testing operations are undertaken in clean rooms where air purity, temperature and humidity are controlled. To ensure stability and integrity of our operations, we maintain clean rooms at our facilities that meet U.S. Federal 209E class 1,000, 10,000 and 100,000 standards. All of our facilities have been certified as meeting the ISO 9002 quality standards by the International Standards Organization. Our facilities in Taiwan, Korea and Malaysia have also been certified as meeting the Quality System 9000 or QS-9000 quality standards. The ISO 9002 certification is required by many countries in connection with sales of industrial products in these countries. The QS-9000 quality standards provide for continuous improvement with an emphasis on the prevention of defects and reduction of variation and waste in the supply chain. Like the ISO 9002 certification, the QS-9000 certification is required by some

semiconductor manufacturers as a threshold indicating a company’s quality control standards. In addition, we have received various vendor awards from our customers for the quality of our products and services.

Competition

We compete in the highly competitive independent semiconductor packaging and testing markets. We face competition from a number of sources, including other independent semiconductor packaging and testing companies, especially those that also offer turnkey packaging and testing services. More importantly, we compete for the business of integrated device manufacturers with in-house packaging and testing capabilities and fabless semiconductor design companies with their own in-house testing capabilities. Some of these integrated device manufacturers have commenced, or may commence, in-house packaging and testing operations in Asia. Furthermore, several independent packaging companies in Asia plan to expand their packaging capacities and enhance their testing capabilities.

Integrated device manufacturers that use our services continuously evaluate our performance against their own in-house packaging and testing capabilities. These integrated device manufacturers may have access to more advanced technologies, and greater financial and other resources than we do. We believe, however, that we can offer greater efficiency and lower costs while maintaining equivalent or higher quality for several reasons. First, we tend to have lower unit costs because of higher utilization rate as compared to the in-house testing operations of integrated device manufacturers. Second, we tend to offer a wider range of products in terms of complexity and technology as compared to the in-house testing operations of integrated device manufacturers, since integrated device manufacturers are less able to utilize individual testers for long periods of time following the migration of product technology.

Environmental Matters

The semiconductor packaging process generates gaseous chemical wastes, principally at the stage at which the copper leads protruding from the plastic or ceramic casings of the semiconductor, commonly referred to as moldings, are plated with tin or lead to improve their electrical conductivity. Liquid waste is produced at the stage where silicon wafers are diced into chips with the aid of diamond saws and cooled with running water. In addition, excess materials on leads and moldings are removed from packaged semiconductors in the trimming and de-junking processes, respectively. We have installed various types of anti-pollution equipment for the treatment of liquid and gaseous chemical waste generated at all of our semiconductor packaging facilities. We believe that we have adopted adequate anti-pollution measures for the effective maintenance of environmental protection standards that are consistent with the semiconductor industry practice in the countries in which our facilities are located. In addition, we believe we are in compliance in all material respects with present environmental laws and regulations applicable to our operations and facilities.

Employees

As of June 30, 2000, we had 16,779 full-time employees serving in the following capacities:

|  | Number of Employees
Direct labor |  |  | 11,142 |
Indirect labor (manufacturing) |  |  | 3,447 |
Indirect labor (administration) |  |  | 1,254 |
Research and development |  |  | 936 |
| Total |  |  | 16,779 |

Eligible employees may participate in the ASE Inc. Employee Share Bonus Plan and the ASE Test Share Option Plans. See “Management — Compensation of Directors, Supervisors and Executive Officers — ASE Inc. Employee Bonus Plan” and “Management — Compensation of Directors, Supervisors and Executive Officers — ASE Test Share Option Plans”.

With the exception of ASE Korea’s employees, our employees are not covered by any collective bargaining arrangements. We believe that our relationship with our employees is good.

Legal Proceedings

We are not involved in material legal proceedings the outcome of which we believe would have a material adverse effect on us.

Criminal charges were brought in December 1998 by the district attorney for Taipei against Jason C.S. Chang, our Chairman, Richard H.P. Chang, our Vice Chairman and Chief Executive Officer, and Chang Yao Hung-ying, our director, and four others for alleged breach of fiduciary duties owed to our affiliate Hung Ching in their capacity as directors and officer of Hung Ching in connection with a land sale transaction in 1992 valued at approximately NT$1.7 billion. It was alleged that the transaction in which Jason C.S. Chang sold the land to Hung Ching unfairly benefited Jason C.S. Chang to the detriment of Hung Ching. Hung Ching at that time was a privately owned company whose principal shareholders were members of the Chang family. Ancillary charges were brought against Jason C.S. Chang, Chang Yao Hung-ying and another for alleged forgery of Hung Ching board resolutions relating to that transaction. Neither Jason C.S. Chang nor Richard H.P. Chang nor Chang Yao Hung-ying believes that he or she committed any offense in connection with such transactions, and all of them are vigorously contesting the alleged charges. If convicted, they would be required to resign from their respective positions with us and our group companies. ASE Inc. is not a party to these proceedings and we do not expect that these charges will result in any liability to us. See “Business — Other Members of the ASE Group” for a description of Hung Ching.

We have been advised by counsel to Messrs. and Mdm. Chang that a judgment in these proceedings may be rendered by the District Court at any time, although there can be no certainty as to the exact timing. Moreover, counsel to Messrs. and Mdm. Chang have advised us that, as these proceedings may not be finally determined until the case has been considered by the District Court, the High Court and the Supreme Court of the ROC, two or three years may elapse until they are fully resolved. As a result, we do not expect that these proceedings will result in a change in our management in the near future, if at all.

Insurance

We have insurance policies covering losses due to fire and we believe that these insurance policies are sufficient for our business. These insurance policies cover the buildings, machinery and equipment at our major production facilities. We do not have business interruption insurance, except in connection with fire. Significant damage to any of our production facilities, whether as a result of fire or other causes, would have a material adverse effect on our results of operations. We are not insured against the loss of key personnel.

RECENT ACQUISITIONS

ASE Chung Li and ASE Korea

In July 1999, we purchased Motorola’s Semiconductor Products Sector operations in Chung Li, Taiwan and Paju, South Korea for the packaging and testing of semiconductors with principally communications, consumer and automotive applications. The businesses are now operated by ASE Chung Li and ASE Korea. We acquired substantially all of the assets of ASE Chung Li for a base price of US$150.0 million in cash, consisting of an initial payment of US$80.0 million at closing and an additional US$70.0 million payable over three years if sales volume targets are met. We acquired 100% of the outstanding shares of ASE Korea for a base price of US$140.0 million in cash, consisting of an initial payment of US$36.0 million and an additional US$104.0 million payable over five years. In addition to the combined base price of US$290.0 million, we also paid an aggregate of approximately US$60.1 million in cash to purchase capital assets at both facilities which were acquired after January 1, 1999 and specified inventories and cash positions at both facilities. Under the acquisition agreements, ASE Inc. acquired a 70.0% interest in each of the two businesses, and ASE Test acquired the remaining 30.0% interest. This division of the investment reflected in part our estimate of the relative packaging and testing values at the facilities. Both facilities provide semiconductor packaging and testing services for Motorola’s Semiconductor Products Sector, and will continue to do so for at least three to five years following the completion of the acquisition under manufacturing services agreements with Motorola. See the combined financial statements of Motorola’s Semiconductor Products Sector Businesses in Taiwan and Korea and our unaudited pro forma financial statements.

ISE Labs

In May 1999, ASE Test purchased 70% of the outstanding shares of ISE Labs. ISE Labs is an independent semiconductor testing company currently based in San Jose, California. ISE Labs also owns Digital Testing Services, Inc., a semiconductor testing company based in Santa Clara, California. ISE Labs offers a broad range of semiconductor testing services, including software program development, electrical design validation, reliability and failure analysis, wafer sort and testing to semiconductor companies, with a focus on its principal market in the Silicon Valley area. ISE Labs specializes in front-end engineering testing, which is performed during and following the circuit design stage of the semiconductor manufacturing process.

The total purchase price for the 70% equity interest in ISE Labs was US$98.0 million. The stock purchase agreement provides that in the event ISE Labs (1) does not consummate an initial public offering of its common stock by December 2001 at or above a specified price or (2) disposes of certain of its material assets, which in the aggregate is greater than 15% of the total assets of ISE Labs as shown on the most recent audited balance sheet of ISE Labs, then ASE Test will be obligated to purchase the remaining 30% equity interest for US$42.0 million plus accrued interest. The purchase price is payable either in cash or ordinary shares of ASE Test’s common stock, at the option of the holders of the remaining shares, who are primarily founders and employees of ISE Labs or its predecessors.

On April 27, 2000, ASE Test purchased $30 million of additional shares of ISE Labs at $8 per share, which was financed through a short-term loan from Citibank, N.A., Taipei OBU. As a result, ASE Test’s ownership in ISE Labs increased from 70.0% to 75.3%. ASE Test plans to purchase up to an additional $40 million of shares at $8 per share during the third quarter of 2000. Upon the completion of this share purchase, ASE Test will own up to 80.0% of the outstanding shares of ISE Labs.

ISE Labs has in the past entered into a multi-year outsourced testing arrangement with a key customer, and may from time to time in the future enter into similar arrangements with its other

75

customers. Under these arrangements, ISE Labs will, among other things: (1) purchase equipment and retain select personnel from its customers and (2) maintain, as well as continually upgrade, its testing facilities and equipment. In return, these customers, will, among other things: (1) outsource all or a portion of their testing requirements to ISE Labs at a negotiated rate; (2) pay monthly service fees to ISE Labs; and (3) provide ISE Labs with technical and logistical support for the testing process.

Universal Scientific

From February through July of 1999, we purchased 22.6% of the outstanding shares of Universal Scientific for approximately NT$3,532.5 million (US$115.0 million), principally through open market purchases on the Taiwan Stock Exchange. We subsequently increased our holding to 23.3% following the open market purchase of additional shares in July and August of 2000. Six out of the nine directors on the Universal Scientific board of directors, including the chairman, are our representatives.

MANAGEMENT

Directors

Our board of directors is elected by our shareholders in a general meeting at which a quorum, consisting of a majority of all issued and outstanding common shares, is present. The Chairman is elected by the board from among the directors. Our seven-member board of directors is responsible for the management of our business.

The term of office for our directors is three years from the date of election. Directors may serve any number of consecutive terms and may be removed from office at any time for a valid reason by a resolution adopted at a general meeting of shareholders. Normally, all board members are elected at the same time, except where the posts of one-third or more of the directors are vacant, at which time a special meeting of shareholders shall be convened to elect directors to fill the vacancies.

The following table sets forth the name of each of our directors, his or her position in ASE Inc., the year they were elected as director and other significant positions within the ASE Group held by them.

These employees are eligible to receive bonuses in the form of common shares of ASE Inc. valued at par. Actual amounts of bonuses to individual employees are determined based upon the employee meeting specified individual performance objectives. We granted an aggregate of 10,980,000 common shares, 30,760,000 common shares, 9,540,000 common shares and 47,833,062 common shares in 1997, 1998, 1999 and 2000, respectively, as stock awards to our employees with a fair market value at the date of grant of NT$543.1 million, NT$2,311.1 million, NT$754.7 million (US$24.5 million) and NT$3,444.0 million (US$111.8 million), respectively.

ASE Test Share Option Plans

Directors, supervisors, and executive officers of ASE Group companies are also eligible to receive options to purchase ordinary shares of ASE Test under share option plans administered by ASE Test. ASE Test currently maintains five option plans: a pre-IPO plan as well as option plans approved in 1996, 1997, 1998, 1999 and 2000. Under ASE Test’s share option plans, directors of ASE Test and employees, advisors and consultants of ASE Test or its affiliates may, at the discretion of a committee of the ASE Test board of directors administering the plan, be granted options to purchase ordinary shares of ASE Test at an exercise price of no less than market value on the date of grant. The committee has complete discretion to determine which eligible individuals are to receive option grants, the number of shares subject to each grant, the vesting schedule to be in effect for each option grant and the maximum term for which each granted option is to remain outstanding, up to a maximum term of five, or in the case of the 1999 and 2000 plan, ten years. ASE Test’s board of directors may amend or modify the plans at any time. As of June 30, 2000, an aggregate of 30,300,000 ordinary shares had been reserved for issuance and 11,580,923 options to purchase ordinary shares remained outstanding under the various plans of ASE Test. An aggregate of 7,095,000 options had been granted to the directors, supervisors and executive officers of ASE Inc. Options granted under the various plans are exercisable at the market price at the date of the grant, which has ranged from an exercise price of US$3.00 to US$25.00, and, in the case of the pre-IPO plan, at an exercise price of US$2.0625 per ordinary share. Options granted under the pre-IPO, 1996, 1997 and 1998 plans are exercisable, in accordance with a vesting schedule, over a period of five years following the respective date of grant, and, in the case of options granted under the 1999 and 2000 plan, over a period of ten years following the date of grant.

ASE Test Taiwan has historically charged ASE Inc. fees for the testing of semiconductors packaged for a small number of customers that prefer to be billed through ASE Inc. for testing services performed by ASE Test Taiwan. These fees amounted to NT$49.5 million (US$1.6 million), NT$81.5 million (US$2.7 million), NT$155.7 million and NT$116.0 million for the six months ended June 30, 2000 and in 1999, 1998 and 1997, respectively. ASE Inc. sold to ASE Test Taiwan at book value a building at an aggregate price of NT$18.4 million (US$0.6 million) in the first half of 2000.

ASE Test Malaysia and ASE Philippines have historically purchased a portion of the raw materials used in their packaging operations, principally leadframes, from ASE Inc. when they face a shortage in the supply of these types of raw materials. These types of raw materials are typically resold by ASE Inc. to ASE Test Malaysia and ASE Philippines at book value. Purchases of raw materials by ASE Test Malaysia amounted to NT$3.1 million (US$0.1 million), NT$14.6 million (US$0.5 million), NT$28.0 million and NT$33.8 million for the six months ended June 30, 2000 and in 1999, 1998 and 1997, respectively. Purchases of raw materials by ASE Philippines amounted to NT$1.2 million (US$0.04 million), NT$2.1 million (US$0.07 million), NT$4.1 million and NT$3.3 million for the six months ended June 30, 2000 and in 1999, 1998 and 1997, respectively.

Upon completion of the development, floor space in the buildings will be sold by Hung Ching at prices to be negotiated between Hung Ching and the buyers. ASE Chung Li and its affiliates will have priority in the purchase of the floor

space. In the event that floor space is sold to persons other than ASE Chung Li, ASE Chung Li will receive 25% of the purchase price. The first phase of the development project is the construction of a building with aggregate floor space of approximately 800,000 square feet, which is expected to be completed in the fourth quarter of 2000. The total value of the first phase of the project, including land and the completed building, is estimated to be NT$2.0 billion. The new building is expected to house ASE Chung Li’s testing operations as well as part of the operations of other ASE Group companies.

In October 1997, J&R Holding entered into agreements with Swiss Bank Corporation to purchase call options on a portion of our US$200 million Zero Coupon Convertible Bonds due 2002. The call options were offered by Swiss Bank Corporation as a part of the repackaging of our convertible bonds by SBC Warburg, an affiliate of Swiss Bank Corporation, into two separate instruments consisting of: (1) US$200 million callable floating rate notes secured by the convertible bonds and (2) call options on the convertible bonds. SBC Warburg decided to repackage the convertible bonds because the adverse market conditions resulting from the Asian financial crisis during the second half of 1997 made it difficult to market the convertible bonds. SBC Warburg was able to obtain commitments for the entire issue of the floating rate notes but, as a result of the adverse market conditions described above, was able to obtain commitments for only a portion of the call options. As a result, Swiss Bank Corporation approached a number of large institutional investors, including J&R Holding, with a proposal to sell a portion of the call options.

J&R Holding decided to purchase the call options because its management considered the call options to be a good investment. Under the first agreement with Swiss Bank Corporation, J&R Holding is required to make four cash payments to Swiss Bank Corporation in November 1998, 1999, 2000 and 2001. In return, J&R Holding has the right to call the convertible bonds back at any time during the period from November 1998 through November 2002. Under the second agreement, Swiss Bank Corporation paid US$200,000 to J&R Holding. In return, Swiss Bank Corporation had the right to sell a portion of the call options to J&R Holding at any time between November 4, 1997 and November 1, 1998. In any event, J&R Holding was required under the automatic exercise provision of the second agreement to purchase these call options upon the expiration of the agreement on November 1, 1998.

EXCHANGE OFFER

In July 1995, we established with Citibank, N.A., as GDS depositary, two depositary receipts facilities, one for the purpose of facilitating the issuance of GDSs sold under Rule 144A and the other for the purpose of facilitating the issuance of GDSs sold pursuant to Regulation S. Each GDS represents five of our common shares. In December 1999, some of our affiliates offered and sold additional GDSs. The GDSs sold under Rule 144A have been designated as eligible for trading in the PORTAL System of the National Association of Securities Dealers, Inc. in the United States. The GDSs sold pursuant to Regulation S are listed on the Stock Exchange of Singapore and the Luxembourg Stock Exchange and quoted on SEAQ International. The closing price for the GDSs sold pursuant to Regulation S on SEAQ International on September 8, 2000 was US$8.94 per GDS.

Concurrently with this offering, we will arrange with our GDS depositary and our ADS depositary for the automatic conversion of each of our outstanding GDSs sold pursuant to Regulation S into one ADS. The ADSs issued upon conversion of our GDSs sold pursuant to Regulation S will be identified by a new CUSIP number. We have applied to have these ADSs listed for trading on the NYSE under the symbol “ASX”. Upon completion of the conversion of our GDSs sold pursuant to Regulation S into ADSs, we intend to delist these GDSs from the Stock Exchange of Singapore and the Luxembourg Stock Exchange and suspend quotation on SEAQ International.

Concurrently with this offering, we are offering to exchange one ADS for each of our outstanding GDSs sold under Rule 144A. The ADSs issued upon exchange of the GDSs sold under Rule 144A will also be identified by the same CUSIP number as that which will identify the ADSs issued upon conversion of the GDSs sold pursuant to Regulation S as described above, and all of those ADSs will be fully fungible for trading on the NYSE. The closing of the exchange offer is conditional upon closing of this offering. Upon the completion of the exchange offer, we will instruct the GDS depositary to terminate the global depositary receipt facility.

Until three months after their initial delivery to investors in this offering, the ADSs offered by this prospectus will not be fungible with, will trade under a different NYSE symbol and will settle with a CUSIP identification number distinct from, the ADSs issued upon conversion of and exchange for the GDSs. After that three-month period, the ADSs offered by this prospectus will become fully fungible with, and will be identified by the same CUSIP number and will be eligible for trading under the same NYSE trading symbol, as the ADSs issued upon conversion of and exchange for the GDSs as described above.

| (8) | any other event or circumstances which would have in our determination or in the determination of the trustee an analogous effect to any of the events in (1) to (7) above including, but not limited to, issues of receipts or certificates entitling holders to receive securities.

Certificates of Payment

Under current ROC law, whenever we issue common shares, we will deliver one or more certificates of payment evidencing the aggregate number of common shares purchased to the purchaser (or the holder, in the case of a distribution of common shares to existing holders, or the subscriber, in the case of a holder subscribing for additional common shares under a rights offering). Each certificate of payment will represent the irrevocable right to receive the relevant number of common shares after all required ROC share issuance procedures have been complied with. We are required under ROC law to file an amendment to our corporate registration within 15 days after we receive the proceeds of an offering. Under ROC securities and exchange law and applicable regulations, we are required to deliver physical common share certificates to the relevant custodian within 30 days after receiving approval from the applicable ROC governmental authorities of our amendment to our corporate registration. We have agreed to issue and deliver physical common share certificates to the ADS custodian in exchange for any certificate of payment held in our ADS facility within 60 days after the date of issuance. During the period before this exchange, the relevant ADS owner will not be able to withdraw the underlying common shares. Except for the restrictions on sale and withdrawal during the three-month period, the certificates of payment we issue will have the same rights to receive distributions and deliver voting instructions as our common shares. Please refer to the section of this prospectus entitled “Description of American Depositary Receipts — Certificate of Payment ADSs” for information regarding certificates of payment that may be held in our ADS facility.

Dividends and Distributions

In general, we are not permitted to distribute dividends or make other distributions to shareholders in any year in which we did not record net income. The ROC Company Law also requires that 10% of annual net income (less prior years’ losses, if any) be set aside as a legal reserve until the accumulated legal reserve equals our paid-in capital. In addition, our Articles of Incorporation require that before a dividend is paid out of our annual net income:

| • | up to 2% of our annual net income (less any gains on the disposal of fixed assets, prior years’ losses and additions to legal and special reserves, if any) should be paid to our directors and supervisors as compensation; and
| • | between 5% and 7% of the annual net income (less any gains on the disposal of fixed assets, prior years’ losses and legal and special reserves, if any) should be paid to our employees as bonuses. The 5% portion is to be distributed to all employees in the form of stock bonuses in accordance with our employee stock bonus plan, while any portion exceeding 5% is to be distributed in accordance with rules established by our board of directors to individual employees who have been recognized as having made special contributions to our company.

At the annual general shareholders’ meeting, our board of directors submits to the shareholders for their approval any proposal for the distribution of a dividend or the making of any other distribution to shareholders from our net income for the preceding fiscal year. All common shares outstanding and fully paid as of the relevant record date are entitled to share equally in any dividend or other distribution so approved. Dividends may be distributed in cash, in

88

##### Table of Contents

the form of common shares or a combination of the two, as determined by the shareholders at the meeting.

We are also permitted to make distributions to our shareholders of additional common shares by capitalizing reserves. However, the capitalized portion payable out of our legal reserve is limited to 50% of the total accumulated legal reserve and the capitalization can only be effected when the accumulated legal reserve exceeds 50% of our paid-in capital.

For information on the dividends we paid in recent years, see “Dividends and Dividend Policy”. For information as to ROC taxes on dividends and distributions, see “Taxation — ROC Taxation — Dividends”.

Changes in Share Capital

Under ROC Company Law, any change in the authorized share capital of a company limited by shares requires an amendment to its Articles of Incorporation. In the case of a public company such as ASE Inc., the approval of the ROC Securities and Futures Commission and the ROC Ministry of Economic Affairs is also required. Authorized but unissued common shares may be issued, subject to applicable ROC law, upon terms as our board of directors may determine.

Preemptive Rights

Under the ROC Company Law, when a ROC company issues new shares for cash, existing shareholders who are listed on the shareholders’ register as of the record date have preemptive rights to subscribe for the new issue in proportion to their existing shareholdings, while a company’s employees, whether or not they are shareholders of the company, have rights to subscribe for 10% to 15% of the new issue. Any new shares that remain unsubscribed at the expiration of the subscription period may be offered by us to the public or privately placed.

In addition, in accordance with the ROC Securities and Exchange Law, a public company that intends to offer new shares for cash must offer to the public at least 10% of the shares to be sold. This percentage can be increased by a resolution passed at a shareholders’ meeting, which would diminish the number of new shares subject to the preemptive rights of existing shareholders.

In connection with the offering, our shareholders have waived their preemptive rights with respect to the common shares represented by the ADSs offered by this prospectus.

Meetings of Shareholders

We are required to hold an ordinary meeting of our shareholders within six months following the end of each fiscal year. These meetings are generally held in Kaohsiung, Taiwan. Extraordinary shareholders’ meetings may be convened by resolution of the board of directors or by the board of directors upon the written request of any shareholder or shareholders who have held 3% or more of the outstanding common shares for more than one year. Extraordinary shareholders’ meetings may also be convened by a supervisor. Notice in writing of general meetings of shareholders, stating the place, time and purpose, must be dispatched to each shareholder at least 20 days, in the case of ordinary meetings, and 10 days, in the case of extraordinary meetings, before the date set for each meeting. A majority of the holders of all issued and outstanding common shares present at a shareholders’ meeting constitutes a quorum for meetings of shareholders.

Under the ROC Company Law, the applicable rules of the Taiwan Stock Exchange and our Articles of Incorporation, we are required to hold an ordinary meeting of our shareholders within six months following the end of each fiscal year.

##### Table of Contents

Voting Rights

Our Articles of Incorporation provide that a holder of common shares has one vote for each common share, except that a holder of more than 3% of the total outstanding common shares is not permitted to vote 0.1% of the number of common shares held by the holder in excess of 3%. There is cumulative voting for the election of directors and supervisors.

In general, a resolution can be adopted by the holders of at least a majority of the common shares represented at a shareholders’ meeting at which the holders of a majority of all issued and outstanding common shares are present. Under ROC Company Law, the approval by at least a majority of the common shares represented at a shareholders meeting in which a quorum of at least two-thirds of all issued and outstanding common shares are represented is required for major corporate actions, including:

| • | amendment to the Articles of Incorporation;
| • | increase in authorized share capital;
| • | transfer of the whole or substantial part of its business or assets;
| • | taking over of the whole of the business of any other company; or
| • | distribution of any stock dividend.

In case of a dissolution or amalgamation of the company, approval by a majority of the common shares represented at a shareholders’ meeting in which a quorum of at least three-fourths of all issued and outstanding common shares are represented is required.

A shareholder may be represented at an ordinary or extraordinary meeting by proxy if a valid proxy form is delivered to us five days before the commencement of the ordinary or extraordinary shareholders’ meeting.

Holders of ADSs will not have the right to exercise voting rights with respect to the underlying common shares, except as described in “Description of American Depositary Receipts — Voting Rights”.

Register of Shareholders and Record Dates

Our share registrar, President Securities Corp., maintains our register of shareholders at its offices in Taipei, Taiwan, and enters transfers of common shares in our register upon presentation of, among other documents, certificates representing the common shares transferred. Under the ROC Company Law and our Articles of Incorporation, we may, by giving advance public notice, set a record date and close the register of shareholders for a specified period in order for us to determine the shareholders or pledgees that are entitled to rights pertaining to the common shares. The specified period required is as follows:

| • | ordinary shareholders’ meeting — one month;
| • | extraordinary shareholders’ meeting — 15 days;
| • | relevant record date — five days.

Annual Financial Statements

At least 10 days before the annual ordinary shareholders’ meeting, our annual financial statements must be available at our principal executive office in Kaohsiung, Taiwan for inspection by the shareholders.

Transfer of Common Shares

The transfer of common shares in registered form is effected by endorsement and delivery of the related share certificates but, in order to assert shareholders’ rights against us, the transferee must have his name and address registered on our register of shareholders. Shareholders are required to file their respective specimen seals, also known as chops, with us. Chops are official stamps widely used in Taiwan by individuals and other entities to authenticate the execution of official and commercial documents.

Acquisition of Common Shares by ASE Inc.

Under the ROC Securities and Exchange Law, as amended on June 30, 2000, we may purchase our own common shares for treasury stock in limited circumstances, including:

| • | to transfer common shares to our employees;
| • | to reserve common shares to be issued upon conversion of convertible securities; and
| • | to increase our shareholders’ equity.

We may purchase our common shares (1) on the Taiwan Stock Exchange, (2) on the over-the-counter market or (3) by means of a public tender offer. These transactions require the approval of a majority of our board of directors at a meeting in which at least two-thirds of the directors are in attendance. The total amount of common shares purchased for treasury stock may not exceed 10% of the total outstanding shares.

These restrictions on acquiring our common shares do not apply to our subsidiaries or affiliates. See “Principal Shareholders”.

Liquidation Rights

In the event of our liquidation, the assets remaining after payment of all debts, liquidation expenses and taxes will be distributed pro rata to the shareholders in accordance with the relevant provisions of the ROC Company Law and our Articles of Incorporation.

Substantial Shareholders and Transfer Restrictions

The ROC Securities and Exchange Law currently requires (1) each director, supervisor, manager or substantial shareholder (that is, a shareholder who together with his or her spouse, minor children or nominees, holds more than 10% of the shares of a publicly listed company) to report any change in that person’s shareholding to the issuer of the shares or the ROC Securities and Futures Commission and (2) each director, supervisor, manager or substantial shareholder holding those common shares for more than a 90-day period to report his or her intent to transfer any shares on the Taiwan Stock Exchange to the ROC Securities and Futures Commission at least three days before the intended transfer, unless the number of shares to be transferred is less than 10,000 shares.

91

##### Table of Contents

In addition, the number of shares that can be sold or transferred on the Taiwan Stock Exchange by any person subject to the restrictions described above on any given day may not exceed:

| • | 0.5% of the outstanding shares of the company in the case of a company with no more than 30 million outstanding shares; or
| • | 0.5% of 30 million shares plus 0.25% of the outstanding shares exceeding 30 million shares in the case of a company with more than 30 million outstanding shares; or
| • | in any case, 10% of the average trading volume (number of shares) on the Taiwan Stock Exchange for the ten consecutive trading days preceding the reporting day on which the director, supervisor, manager or substantial shareholder reports the intended share transfer to the ROC Securities and Futures Commission.

These restrictions do not apply to sales or transfers of our ADSs.

DESCRIPTION OF AMERICAN DEPOSITARY RECEIPTS

Citibank, N.A., will act as the depositary for the American Depositary Shares. Citibank’s depositary offices are located at 111 Wall Street, New York, New York 10005. American Depositary Shares are commonly referred to as “ADSs” and represent ownership interests in securities that are on deposit with the depositary. ADSs are normally represented by certificates that are commonly known as “American Depositary Receipts” or “ADRs”. The depositary typically appoints a custodian to safekeep the securities on deposit. In this case, the custodian will be Citibank, N.A., Taipei Branch, located at Citicorp Center, 52 Min Sheng E. Road, Section 4, Taipei, Taiwan, ROC.

We have appointed Citibank as depositary bank pursuant to a deposit agreement. A copy of the deposit agreement is on file with the SEC under cover of a Registration Statement on Form F-6. You may obtain a copy of the deposit agreement from the SEC’s Public Reference Room at 450 Fifth Street, N.W., Washington, D.C. 20549. Please refer to Registration Number 333-12468 when retrieving your copy.

We are providing you with a summary description of the material terms of the ADSs and of your material rights as an owner of ADSs. Please remember that summaries by their nature lack the precision of the information summarized and that your rights and obligations as an owner of ADSs will be determined by reference to the terms of the deposit agreement and not to this summary. We urge you to review the deposit agreement in its entirety.

Each ADS represents five common shares on deposit with the custodian. An ADS will also represent any other property received by the depositary bank or the custodian on behalf of the owner of the ADS but that has not been distributed to the owners of ADSs because of legal restrictions or practical considerations. Until the completion of all required ROC share issuance procedures, the ADSs offered by this prospectus will represent certificates of payment, with each certificate of payment representing the irrevocable right to receive the relevant number of common shares. The depositary will establish procedures for the automatic conversion of ADSs representing the certificates of payment to ADSs representing common shares upon confirmation of the conversion certificates of payment for common shares in the ROC.

If you become an owner of ADSs, you will become a party to the deposit agreement and therefore will be bound to its terms and to the terms of the ADR that represents your ADSs. The deposit agreement and the ADR specify our rights and obligations as well as your rights and obligations as an owner of ADSs and those of the depositary. As an ADS owner you appoint the depositary to act on your behalf for the common shares represented by your ADSs, either upon (1) your specific instructions when we call a meeting of shareholders, distribute an elective dividend or make a rights offering, or (2) the specific terms of the deposit agreement to receive any dividends we distribute in NT dollars or common shares and to convert the NT dollars received. The deposit agreement is governed by New York law. However, our obligations to the holders of common shares will continue to be governed by ROC laws, which may be different from the laws in the United States. In addition, we note that the laws and regulations of the ROC may restrict the deposit and withdrawal of our common shares into or from the depositary receipts facility. Under ROC laws and regulations, as currently in effect, shares may be accepted for deposit and ADSs may be issued under the terms of the deposit agreement only in the following circumstances:

| (1) upon obtaining regulatory approval from the ROC Securities and Futures Commission;
| (2) upon dividend or a free distribution of common shares to existing shareholders;
| (3) upon the exercise by existing shareholders of their preemptive rights in connection with capital increases for cash; and

93

##### Table of Contents

| (4) as permitted under the deposit agreement, the purchase directly by a person or through the depositary bank of common shares on the Taiwan Stock Exchange for the deposit in the depositary receipt facility, provided that the total number of ADSs outstanding after an issuance described in this paragraph (4) does not exceed the number of ADSs issued and previously approved by the ROC Securities and Futures Commission in connection with the offering plus any ADSs created under clauses (2) and (3) described above.

Under ROC laws and regulations, the common shares deposited under the deposit agreement may be withdrawn upon cancellation of the corresponding ADSs in the following circumstances:

| • | upon the sale of the common shares on the Taiwan Stock Exchange; and
| • | upon the appointment of eligible ROC brokerage firm to the holding of common shares on the investor’s behalf in a designated account in the ROC.

For a more complete description of these deposit or withdrawal restrictions see “Annex B — Foreign Investment and Exchange Controls in the ROC — Depositary Receipts”.

As an owner of ADSs, you may hold your ADSs either by means of an ADR registered in your name or through a brokerage or safekeeping account. If you decide to hold your ADSs through your brokerage or safekeeping account, you must rely on the procedures of your broker or bank to assert your rights as an ADS owner. Please consult with your broker or bank to determine what those procedures are. This summary description assumes you have opted to own the ADSs directly by means of an ADR registered in your name. In addition, except as otherwise described, when we refer to our ADSs and the common shares represented by our ADSs, we assume that the ADSs you hold represent our common shares, rather than certificates of payment.

Certificate of Payment ADSs

Under the terms of the deposit agreement, the depositary may issue ADSs representing certificates of payment that represent the right to receive our newly-issued common shares, also called certificate of payment ADSs, rather than ADSs representing our common shares. Certificate of payment ADSs will be treated as ADSs issued under the terms of the deposit agreement except that:

| • | certificate of payment ADSs will not be fungible with ADSs and will be separately identified until exchanged for ADSs by the depositary;
| • | certificates of payment may not be withdrawn from the ADR facility;
| • | certificate of payment ADSs may not be exchanged for common shares;
| • | certificate of payment ADSs will trade on the NYSE under the temporary trading symbol “ASX Pr”;
| • | certificate of payment ADSs will only be issued in book-entry form through DTC;
| • | certificate of payment ADSs are not eligible for pre-cancellation sales or pre-release transactions; and
| • | distributions made on certificate of payment ADSs shall be made only on the basis of distributions received for certificates of payment held by the depositary.

Certificate of payment ADSs will be exchanged automatically into ADSs upon receipt by the depositary of common shares in exchange for certificates of payment. Until that exchange has been completed, the ADSs offered by this prospectus will represent interests in the certificates of payment held by our ADS depositary.

Dividends and Distributions

As a holder, you generally have the right to receive the distributions we make on the securities deposited with the custodian, subject always to the laws and regulations of the ROC. Your receipt of these distributions may be limited, however, by practical considerations and legal limitations. Holders will receive these distributions under the terms of the deposit agreement in proportion to the number of ADSs owned as of a specified record date.

In the event that, for any reason, any common shares held on deposit with the custodian are not entitled to the full proportion of any distribution we may make (including certificates of payment described above), we have agreed to provide the depositary with a list of the common shares for which a full proportion of the distribution may not be made and direct the depositary to adjust the amount of the distribution upon those common shares accordingly.

Distributions of Cash

Whenever we make a cash distribution upon the common shares held on deposit with the custodian, we will notify the depositary. Upon receipt of our notice of the distribution, the depositary will arrange for the funds to be converted into U.S. dollars and will distribute the U.S. dollars to the holders.

The conversion into U.S. dollars will take place only if practicable and if the U.S. dollars are transferable to the United States. The amounts distributed to holders will be net of the fees, expenses, taxes and governmental charges payable by holders under the terms of the deposit agreement. The depositary will apply the same method for distributing the proceeds of the sale of any property held by the custodian for securities on deposit.

Distributions of Shares

Whenever we make a free distribution of common shares for the securities on deposit with the custodian, we will notify the depositary and deposit the applicable number of shares with the custodian. Upon receipt of notice of the deposit, the depositary will, subject to ROC law, either distribute to holders new ADSs representing the common shares deposited or modify the ratio of ADSs representing our common shares, in which case each ADS you own will represent rights and interests in the additional common shares so deposited. Only whole new ADSs will be distributed. Fractional entitlements to ADSs will be sold and the proceeds of the sale will be distributed as in the case of a cash distribution.

The distribution of new ADSs or the modification of the ADS-to-common share ratio upon a distribution of common shares will be made net of the fees, expenses, taxes and governmental charges payable by holders under the terms of the deposit agreement. In order to pay taxes or governmental charges, the depositary may sell all or a portion of the new common shares so distributed.

No distribution of new ADSs will be made if it would violate any law or if it is not operationally practicable. If the depositary does not distribute new ADSs as described above, it will use its best efforts to sell the common shares received and will distribute the proceeds of the sale as in the case of a distribution of cash. In addition, if the number of common shares to which any holder is entitled is not five or an integral multiple of five, the depositary will use its best efforts to cause the sale of these shares and distribute the proceeds of that sale to the holders as in the case of a distribution in cash.

Distributions of Rights

Whenever we intend to distribute rights to purchase additional common shares, we will give prior notice to the depositary and we will assist the depositary in determining whether it is lawful and reasonably practicable to distribute rights to purchase additional ADSs to holders.

95

##### Table of Contents

The depositary will establish procedures to distribute rights to purchase additional ADSs to holders and to enable these holders to exercise these rights if it is lawful and reasonably practicable to make the rights available to holders of ADSs. You may have to pay fees, expenses, taxes and other governmental charges to subscribe for the new ADSs upon the exercise of your rights. The depositary is not obligated to establish procedures to facilitate the distribution and exercise by holders of rights to purchase new common shares directly rather than new ADSs.

The depositary will not distribute the rights to you if:

| • | we do not timely request that the rights be distributed to you or we request that the rights not be distributed to you;
| • | we fail to deliver satisfactory documents to the depositary; or
| • | the depositary determines that it is not reasonably practicable to distribute the rights.

The depositary will sell the rights that are not exercised or not distributed if the sale is lawful and reasonably practicable. The proceeds of the sale will be distributed to holders as in the case of a cash distribution. If the depositary is unable to sell the rights, it will allow the rights to lapse, in which case you will receive no value for the rights.

Elective Distributions

Whenever we intend to distribute a dividend payable at the election of shareholders either in cash or in common shares, we will give timely notice to the depositary and will indicate whether we wish the elective distribution to be made available to you. If we decide to make the elective distribution available to you, we will assist the depositary to determine whether this distribution is lawful and reasonably practicable.

The depositary will make the election available to you only if it is reasonably practicable and if we have provided all of the documentation contemplated in the deposit agreement. In this case, the depositary will establish procedures to enable you to elect to receive either cash or additional ADSs.

Other Distributions

Whenever we intend to distribute property other than cash, common shares or rights to purchase additional common shares, we will notify the depositary in advance and indicate whether we wish the distribution to be made to you. If so, we will assist the depositary in determining whether the distribution to holders is lawful and reasonably practicable.

If it is reasonably practicable to distribute the property to you and if we provide all of the documentation contemplated in the deposit agreement, the depositary will distribute the property to the holders in a manner it deems practicable.

The distribution will be made net of fees, expenses, taxes and governmental charges payable by holders under the terms of the deposit agreement. In order to pay these taxes and governmental charges, the depositary may sell all or a portion of the property received.

The depositary will not distribute the property to you and will sell the property if:

| • | we do not timely request that the property be distributed to you or we request that the property not be distributed to you; or
| • | we fail to deliver satisfactory documents to the depositary; or
| • | the depositary determines that all or a portion of the distribution to you is not reasonably practicable.

96

##### Table of Contents

The proceeds of the sale will be distributed to holders as in the case of a cash distribution.

Changes Affecting Our Common Shares

The common shares held on deposit for your ADSs may change from time to time. For example, there may be a change in nominal or par value, a split-up, cancellation, consolidation or reclassification of our common shares or we may undertake a recapitalization, reorganization, merger, consolidation or sale of assets.

If any change were to occur, your ADSs would, to the extent permitted by law, represent the right to receive the property received or exchanged for the common shares held on deposit. The depositary may in these circumstances deliver new ADSs to you or call for the exchange of your existing ADSs for new ADSs. If the depositary may not lawfully distribute the property to you, the depositary may sell the property and distribute the net proceeds to you as in the case of a cash distribution.

Issuance of ADSs Upon Deposit of Common Shares

Subject to limitations set forth in the deposit agreement and the ADRs, the depositary may create ADSs on your behalf if you or your broker deposit common shares with the custodian. The depositary will deliver these ADSs to the person you indicate only after you pay any applicable issuance fees and any charges and taxes payable for the transfer of the common shares to the custodian.

The depositary will refuse to accept our common shares for deposit whenever we have notified the depositary that we have restricted the transfer of those common shares to comply with ownership restrictions under ROC laws.

In the event there are new common shares with rights, including rights to dividends, that are different from the existing common shares held by the depositary, we may instruct the depositary to (1) refuse to accept the new common shares for deposit or (2) issue ADSs representing the new common shares that are separate and distinct from the ADSs representing the existing common shares.

In the event we instruct the depositary to issue ADSs representing the new common shares, these new ADSs will be distinguished from the existing ADSs through different CUSIP numbering and legending, if necessary. Upon written notice from us to the depositary that the new common shares no longer have different rights from the existing common shares, the depositary will (1) notify holders of the new ADSs and provide them with an opportunity to exchange their ADSs and (2) take the necessary actions to remove the distinctions between the two types of ADSs.

The issuance of ADSs may be delayed until the depositary bank or the custodian receives confirmation that all required approvals, if applicable, have been given and that the common shares have been duly transferred to the custodian. The depositary will only issue ADSs in whole numbers.

When you make a deposit of common shares, you will be responsible for transferring good and valid title to the depositary. Accordingly, you will be deemed to represent and warrant that:

| • | the common shares are duly authorized, validly issued, fully paid, non-assessable and legally obtained;
| • | all preemptive and similar rights, if any, with respect to the common shares have been validly waived or exercised;
| • | you are duly authorized to deposit the common shares;

97

##### Table of Contents

| • | the common shares presented for deposit are free and clear of any lien, encumbrance, security interest, charge, mortgage or adverse claim, and are not, and the ADSs issuable upon deposit will not be, “restricted securities” as defined in the deposit agreement; and
| • | the common shares presented for deposit have not been stripped of any rights or entitlements.

If any of the representations or warranties are incorrect in any way, we and the depositary may, at your cost and expense, take any and all actions necessary to correct the consequences of the misrepresentations.

The term “restricted securities” is defined in the deposit agreement as common shares:

| • | acquired directly or indirectly from us or our affiliates in a transaction not involving a public offering and thus subject to resale limitations under the Securities Act;
| • | held directly or indirectly by an officer, director or our affiliates; or
| • | subject to other restrictions under applicable laws, our Articles of Incorporation, the rules and regulations of an applicable securities exchange or a shareholders agreement.

Withdrawal of Common Shares Upon Cancellation of ADSs

Subject always to the withdrawal of deposited property being permitted under ROC laws and regulations, as a holder, you will be entitled to present your ADSs to the depositary for cancellation and then receive the corresponding number of underlying common shares at the custodian’s office. However, under current ROC law, if you wish to withdraw the common shares underlying your ADSs from the ADR facility, you will be required to appoint an eligible agent in the ROC to open (1) a securities trading account with a local brokerage firm after receiving an approval from the Taiwan Stock Exchange and (2) a bank account to pay ROC taxes, remit funds, exercise shareholders’ rights and perform any other functions as you may designate upon withdrawal. In addition, you will also be required to appoint an eligible custodian bank to hold our common shares in safekeeping, make confirmations and settle trades and report all relevant information. Without appointing a broker or opening the required accounts, you would not be able subsequently to sell our common shares on the Taiwan Stock Exchange or otherwise. These laws may change from time to time. We cannot assure you that current ROC law will remain in effect or that future changes in ROC law will not adversely affect your ability to withdraw our common shares from the ADR facility.

You may also request that our common shares represented by your ADSs be sold on your behalf. The depositary may require that you deliver your request for sale in writing. Any sale of our common shares will be conducted according to applicable ROC law through a securities company in the ROC on the Taiwan Stock Exchange or in other manner as is permitted under applicable ROC law. Any sale will be at your risk and expense. You may also be required to enter into a separate agreement to cover the terms of the sale of our common shares.

Upon receipt of any proceeds from any sale, subject to any restrictions imposed by ROC law and regulations, the depositary shall convert the proceeds into U.S. dollars and distribute the proceeds to you, net of any fees, expenses, taxes or governmental charges (including, without limitation, any ROC and U.S. taxes) incurred in connection with the sale. Sales of our common shares may be subject to ROC taxation on capital gains and will be subject to a securities transaction tax in the ROC. The ROC does not currently impose capital gains tax on ROC securities transactions, but we cannot assure you that a capital gains tax will not be imposed in the future or the manner in which any ROC capital gains tax would be imposed or calculated.

In order to withdraw the common shares represented by your ADSs, you will be required to pay to the depositary the fees for cancellation of ADSs and any charges and taxes payable upon the transfer of the common shares being withdrawn. You assume the risk for delivery of all funds

98

##### Table of Contents

and securities upon withdrawal. Once canceled, the ADSs will not have any rights under the deposit agreement.

During any period in which the custodian holds a certificate of payment representing the common shares underlying your ADSs, you will not be entitled to withdraw common shares upon surrender of your ADSs. In addition, under ROC regulations applicable to offerings of ADSs, newly-issued shares of ROC companies initially offered in ADS form may not be withdrawn from the ADS facility until three months following the initial delivery of the ADSs.

If you hold an ADR registered in your name, the depositary may ask you to provide proof of identity and genuineness of any signature and other documents as the depositary may deem appropriate before it will cancel the ADSs represented by your ADR. The withdrawal of the common shares represented by your ADSs may be delayed until the depositary receives satisfactory evidence of compliance with all applicable laws and regulations. Please keep in mind that the depositary will only accept ADSs for cancellation that represent a whole number of securities on deposit. We have reporting obligations under ROC law in respect of the ADR facility. In order to enable us to gather the information necessary for these reporting obligations, you will be asked to complete and sign a certification upon withdrawal of common shares from the ADR facility. In this certification you will be asked to disclose, among other information, the name, nationality and address of the beneficial owner of the ADSs presented for cancellation, the number of common shares owned by the beneficial owner and whether certain affiliations exist between the beneficial owner and ASE Inc. The ADS depositary will refuse to release common shares to you until you deliver a completed and signed certification to it.

You will have the right to withdraw the common shares represented by your ADSs at any time except for:

| • | temporary delays that may arise because (1) the transfer books for the common shares or ADSs are closed, or (2) our common shares are immobilized on account of a shareholders’ meeting or a payment of dividends;
| • | obligations to pay fees, taxes and similar charges; and
| • | restrictions imposed because of laws or regulations applicable to ADSs or the withdrawal of securities on deposit.

The deposit agreement may not be modified to impair your right to withdraw the securities represented by your ADSs except to comply with mandatory provisions of law.

Voting Rights

Except as described below, you generally have no right under the deposit agreement to instruct the depositary to exercise the voting rights for the common shares represented by your ADSs. Instead, by accepting ADSs or any beneficial interest in ADSs, you will be deemed to have authorized and directed the depositary to appoint our Chairman or his designee to represent you at our shareholders’ meetings and to vote the common shares deposited with the custodian according to the terms of the ADSs. The voting rights of holders of common shares are described in “Description of Common Shares — Voting Rights”.

The depositary will mail to you any notice of shareholders’ meeting received from us together with information explaining how to instruct the depositary to exercise the voting rights of the securities represented by ADSs.

If we fail to timely provide the depositary with an English language translation of our notice of meeting or other materials related to any meeting of owners of common shares, the depositary will endeavor to cause all the deposited securities represented by ADSs to be present at the applicable meeting, insofar as practicable and permitted under applicable law, but will not cause those securities to be voted.

##### Table of Contents

If the depositary timely receives voting instructions from owners of at least 51.0% of the outstanding ADSs to vote in the same direction regarding one or more resolutions to be proposed at the meeting, including election of directors and supervisors, the depositary will notify the instructions to our Chairman or his designee to attend the meeting and vote all the securities represented by the holders’ ADSs in accordance with the direction received from owners of at least 51.0% of the outstanding ADSs.

If we have timely provided the depositary with the materials described in the deposit agreement and the depositary has not timely received instructions from holders of at least 51.0% of the outstanding ADSs to vote in the same direction regarding any resolution to be considered at the meeting, then, you will be deemed to have authorized and directed the depositary bank to give a discretionary proxy to our Chairman or his designee to attend and vote at the meeting the common shares represented by your ADSs in any manner he or his designee may wish, which may not be in the interests of holders.

Please note that the ability of the depositary to carry out voting instructions may be limited by practical and legal limitations and the terms of the securities on deposit. We cannot assure you that you will receive voting materials in time to enable you to return voting instructions to the depositary in a timely manner.

Fees and Charges

As an ADS owner, you will be required to pay the following service fees to the depositary:

Service |  | Fees
• issuance of ADSs upon the deposit of common shares |  | up to US$0.05 per ADS issued
• cancellation of ADSs |  | up to US$0.05 per ADS canceled
• distribution of ADSs pursuant to exercise of rights to purchase additional ADSs |  | up to US$0.05 per ADS issued
• distribution of cash (that is, upon the sale of rights and other entitlements) |  | up to US$0.02 per ADS held

The depositary has waived its fees for the issuance of ADSs in connection with this offering.

As an ADS owner you will also be responsible to pay fees and expenses incurred by the depositary and taxes and governmental charges such as:

| • | fees for the transfer and registration of common shares charged by the registrar and transfer agent for the common shares in Taiwan upon deposit and withdrawal of common shares;
| • | expenses and charges incurred for converting foreign currency into U.S. dollars;
| • | fees and expenses incurred by the depositary in compliance with exchange controls or other regulatory requirements;
| • | expenses for cable, telex and fax transmissions and for delivery of securities; or
| • | taxes and duties upon the transfer of securities, for example, when common shares are deposited or withdrawn from deposit.

We have agreed to pay other specified charges and expenses of the depositary. Note that the fees and charges you may be required to pay may vary over time and may be changed by us and by the depositary. You will receive prior notice of these changes.

##### Table of Contents

Amendments and Termination

We may agree with the depositary to modify the deposit agreement at any time without your consent. We undertake to give holders 30 days’ prior notice of any modifications that would materially prejudice any of their substantial rights under the deposit agreement. We will not consider to be materially prejudicial to your substantial rights any modifications or supplements that are reasonably necessary for the ADSs to be registered under the Securities Act or to be eligible for book-entry settlement, in each case without imposing or increasing the fees and charges you are required to pay. In addition, we may not be able to provide you with prior notice of any modifications or supplements that are required to accommodate compliance with applicable provisions of law.

You will be bound by the modifications to the deposit agreement if you continue to hold your ADSs after the modifications to the deposit agreement become effective. The deposit agreement cannot be amended to prevent you from withdrawing the common shares represented by your ADSs except as permitted by law.

We have the right to direct the depositary to terminate the deposit agreement. Similarly, the depositary may in certain circumstances on its own initiative terminate the deposit agreement. In either case, the depositary must give notice to the holders at least 30 days before termination.

Upon termination, the following will occur under the deposit agreement:

| • | For a period of six months after termination, subject always to the withdrawal of deposited property being permitted under ROC laws and regulations, you will be able to request the cancellation of your ADSs and the withdrawal of the common shares represented by your ADSs and the delivery of all other property held by the depositary in connection with those common shares on the same terms as before the termination. During the six months’ period the depositary will continue to collect all distributions received on the common shares on deposit but will not distribute any property to you until you request the cancellation of your ADSs.
| • | After the expiration of the six months’ period, the depositary may sell the securities held on deposit. The depositary will hold the proceeds from the sale and any other funds then held for the holders of ADSs in a non-interest bearing account. At that point, the depositary will have no further obligations to holders other than to account for the funds then held for the holders of ADSs still outstanding.

Books of Depositary

The depositary will maintain ADS holder records at its depositary office. You may inspect the records at the depositary’s office during regular business hours but solely for the purpose of communicating with other holders in the interest of business matters relating to the ADSs and the deposit agreement.

The depositary will maintain in New York facilities to record and process the issuance, cancellation, combination, split-up and transfer of ADRs. These facilities may be closed from time to time, to the extent not prohibited by law.

##### Table of Contents

Limitations on Obligations and Liabilities

The deposit agreement limits our obligations and the depositary’s obligations to you. Please note the following:

| • | We and the depositary are obligated only to take the actions specifically stated in the deposit agreement without negligence or bad faith.
| • | The depositary disclaims any liability for any failure to carry out voting instructions, for any manner in which a vote is cast or for the effect of any vote, provided it acts in good faith and in accordance with the terms of the deposit agreement.
| • | The depositary disclaims any liability for any failure to determine the lawfulness or practicality of any action, for the content of any document forwarded to you on our behalf or for the accuracy of any translation of such a document, for the investment risks associated with investing in common shares, for the validity or worth of those shares, for any tax consequences that result from the ownership of ADSs, for the credit-worthiness of any third party, for allowing any rights to lapse under the terms of the deposit agreement, for the timeliness of any of our notices or for our failure to give notice.
| • | We and the depositary will not be obligated to perform any act that is inconsistent with the terms of the deposit agreement.
| • | We and the depositary disclaim any liability if we are prevented or forbidden from acting on account of any law or regulation, any provision of our Articles of Incorporation, any provision of any securities on deposit or by reason of any act of God or war or other circumstances beyond our control.
| • | We and the depositary disclaim any liability by reason of any exercise of, or failure to exercise, any discretion provided for the deposit agreement or in our Articles of Incorporation or in any provisions of the securities on deposit.
| • | We and the depositary further disclaim any liability for any action or inaction in reliance on the advice or information received from legal counsel, accountants, any person presenting common shares for deposit, any holder of ADSs or authorized representative, or any other person believed by either of us in good faith to be competent to give such advice or information.
| • | We and the depositary also disclaim liability for the inability by a holder to benefit from any distribution, offering, right or other benefit which is made available to holders of common shares but is not, under the terms of the deposit agreement, made available to you.
| • | We and the depositary may rely without any liability upon any written notice, request or other document believed to be genuine and to have been signed or presented by the proper parties.

Pre-Release Transactions

The depositary will not deliver common shares before the receipt for cancellation of ADSs. The depositary may, however, in some circumstances, issue ADSs before receiving common shares for deposit. These transactions are commonly referred to as “pre-release transactions”.

The deposit agreement limits the aggregate size of pre-release transactions and imposes a number of conditions on pre-release transactions such as the need to receive collateral, the type of collateral required, and the need to receive written representations indicating that the recipient of pre-release ADSs owns the underlying common shares to be deposited and unconditionally

102

##### Table of Contents

guarantees to deliver the shares to the depositary upon request. The depositary may retain the compensation received from the pre-release transactions.

Taxes

You will be responsible for the taxes and other governmental charges payable on the ADSs and the securities represented by the ADSs. We, the depositary and the custodian may deduct from any distribution the taxes and governmental charges payable by holders and may sell any and all property on deposit to pay the taxes and governmental charges payable by holders. You will be liable for any deficiency if the sale proceeds do not cover the taxes that are due.

The depositary may refuse (1) to issue ADSs, (2) to deliver, transfer, split and combine ADRs or (3) to release securities on deposit until all taxes and charges are paid by the applicable holder. The depositary and the custodian may take reasonable administrative actions to obtain tax refunds and reduced tax withholding for any distributions on your behalf. However, you may be required to provide to the depositary and to the custodian proof of taxpayer status and residence and other information as the depositary and the custodian may require to fulfill legal obligations. You are required to indemnify us, the depositary and the custodian for any claims with respect to taxes based on any tax benefit obtained for you.

Foreign Currency Conversion

The depositary will arrange for the conversion of all foreign currency received into U.S. dollars if the conversion is lawful and practical, and it will distribute the U.S. dollars in accordance with the terms of the deposit agreement. You may have to pay fees and expenses incurred in converting foreign currency, such as fees and expenses incurred in complying with currency exchange controls and other governmental requirements.

If the conversion of foreign currency is not practical or lawful, or if any required approvals are denied or not obtainable at a reasonable cost or within a reasonable period, the depositary may take the following actions in its discretion:

| • | convert the foreign currency to the extent practical and lawful and distribute the U.S. dollars to the holders for whom the conversion and distribution is lawful and practical;
| • | distribute the foreign currency to holders for whom the distribution is lawful and practical; or
| • | hold the foreign currency without liability for interest for the applicable holders.

Under ROC laws and regulations relating to foreign exchange control, a depositary may, without obtaining further approvals from the Central Bank of China or any other governmental authority or agency of the ROC, convert NT dollars into other currencies, including U.S. dollars, in connection with the following:

| • | proceeds of the sale of common shares represented by depositary receipts;
| • | proceeds of the sale of common shares received as stock dividends and deposited into the depositary receipt facility; and
| • | any cash dividends or cash distributions received.

103

##### Table of Contents

In addition, a depositary, without governmental approval, may also convert incoming payments into NT dollars for (1) purchases of underlying common shares for deposit into the depositary receipt facility against the creation of additional depositary receipts or (2) subscription payments for rights offering through us.

Under current ROC law, a holder, without obtaining further approval from the Central Bank of China, may convert NT dollars into other currencies, including U.S. dollars, upon receipt of the proceeds (1) of the sale of any underlying common shares withdrawn from the depositary receipt facility, (2) received as a stock dividend received upon the common shares and (3) any cash dividends or distribution paid upon the common shares.

COMMON SHARES ELIGIBLE FOR FUTURE SALE

Upon completion of this offering, the ADSs sold in this offering, the ADSs issued upon conversion of our GDSs sold pursuant to Regulation S, and any ADSs issued in connection with the exchange offer being conducted concurrently with this offering, in aggregate approximately 38.4 million ADSs, assuming no exercise of the underwriters’ over-allotment option, will be freely tradeable within the United States without restriction or further registration under the Securities Act by persons other than us or our “affiliates” as the term is defined in Rule 144 under the Securities Act.

Apart from (1) the 32,280,550 common shares underlying GDSs sold to qualified institutional buyers in reliance on Rule 144A under the Securities Act on December 15, 1999 and (2) the 640,086,143 common shares currently owned by our affiliates, all of our outstanding common shares are freely tradable within the United States without restriction or registration under the Securities Act. There is no public market for the common shares in the United States. The common shares are listed on the Taiwan Stock Exchange. We intend to list the ADSs on the New York Stock Exchange. The depositary may create ADSs upon deposit of common shares with the custodian. The number of common shares that can be deposited in the depositary receipt facility is limited by the terms of the deposit agreement and total number of ADS previously approved by the ROC Securities and Futures Commission.

The common shares owned by these qualified institutional buyers and our affiliates are “restricted securities” as that term is defined in Rule 144 under the Securities Act. Restricted securities may be sold in the public market in the United States only if they are registered or if they qualify for an exemption from registration, including under Rule 144 or 701 under the Securities Act, which rules are summarized below.

Rule 144

In general, under Rule 144 as currently in effect, beginning 90 days after the date of this prospectus, a person who has beneficially owned shares for at least one year would be entitled to sell within any three-month period a number of shares that does not exceed the greater of:

| • | 1% of the number of shares then outstanding, which will equal approximately 20.8 million shares immediately after this offering; or
| • | the average weekly trading volume of the shares on the NYSE during the four calendar weeks preceding the filing of a notice on Form 144 with respect to that sale.

Sales under Rule 144 are also subject to the manner of sale provisions and notice requirements and to the availability of current public information about us.

Under Rule 144(k), a person who is not one of our affiliates at any time during the three months preceding a sale, and who has beneficially owned the shares proposed to be sold for at least two years, including the holding period of any prior owner other than an affiliate, is entitled to sell these shares without complying with the manner of sale, public information, volume limitation or notice provisions of Rule 144.

Rule 701

In general, under Rule 701 of the Securities Act as currently in effect, each of our employees, consultants or advisors who purchases shares from us in connection with a compensatory share plan or other written agreement is eligible to resell these shares 90 days after the effective date of this offering in reliance on Rule 144, but without compliance with some restrictions, including the holding period, contained in Rule 144.

Lock-Up Agreements

We have agreed for a period of 90 days after the date of this prospectus not to sell, transfer or otherwise dispose of, and not to announce an intention to sell, transfer or otherwise dispose of, without the prior written consent of Goldman Sachs (Asia) L.L.C.:

| • | any of our common shares or depositary receipts representing our common shares;
| • | any common shares of our subsidiaries or controlled affiliates or depositary receipts representing those shares; and
| • | any securities that are substantially similar to the common shares or depositary receipts referred to above, including any securities that are convertible into, exchangeable for or otherwise represent the right to receive the common shares or depositary receipts referred to above;

other than pursuant to (1) exercise of options under employee stock option plans existing on the date of this prospectus and (2) the conversion or exchange of convertible or exchangeable securities outstanding as of the date of this prospectus, which in each case is described in this prospectus.

In addition, we have agreed to cause each of our subsidiaries and controlled affiliates not to sell, transfer or otherwise dispose of, and not to announce an intention to sell, transfer or otherwise dispose of, for a period of 90 days after the date of this prospectus without the prior written consent of Goldman Sachs (Asia) L.L.C., any of the securities referred to above, other than pursuant to (1) exercise of options under employee stock option plans existing on the date of this prospectus and (2) the conversion or exchange of convertible or exchangeable securities outstanding as of the date of this prospectus, which in each case is described in this prospectus.

Furthermore, ASE Enterprises, our principal shareholder, and each of Jason C. S. Chang, Richard H. P. Chang, Chang Yao Hung-ying and Feng Mei-Jean have also entered into a similar 90-day lock-up agreement with respect to our common shares, depositary receipts representing our common shares and securities that are substantially similar to our common shares or depositary receipts representing our common shares.

These restrictions do not apply to:

| • | the 20,000,000 ADSs and the common shares represented being offered in connection with this offering;
| • | up to 2,774,778 ADSs and the common shares represented that may be purchased by the underwriters pursuant to their over-allotment option;
| • | the issuance of common shares of ASE Inc. pursuant to any stock dividend payable to all holders of common shares of ASE Inc. (including common shares represented by the ADSs) as of a record date subsequent to the date of this prospectus;
| • | employee bonuses in the form of common shares relating to our fiscal year ended December 31, 1999 approved at our annual general meeting of shareholders held on July 11, 2000;

106

##### Table of Contents

| • | the issuance and sale by any subsidiary or controlled affiliate of equity securities where our beneficial ownership interest in that subsidiary or controlled affiliate will not decrease as a result of such issuance or sale; and
| • | the issuance and the sale by Universal Scientific of a number of its common shares not in excess of 18% of its outstanding common shares as of the date of this prospectus (or depositary receipts representing up to the number of its common shares, or debt or other securities initially convertible into not more than the number of common shares or depositary receipts). The number of Universal Scientific’s common shares outstanding as of the date of this prospectus is approximately 1,026.6 million.

We are not aware of any plans by any major shareholders to dispose of significant numbers of common shares. No assurances can be given, however, that one or more existing shareholders or owners of securities convertible or exchangeable into or exercisable for our common shares will not dispose of significant numbers of common shares. In addition, following completion of this offering several of our subsidiaries and affiliates will continue to hold common shares, depositary shares representing common shares, and options to purchase common shares. We or they may decide to sell those securities in the future. See “Principal Shareholders” for a description of our significant shareholders and ASE Group companies that hold our common shares. No prediction can be made as to the effect, if any, that future sales of ADSs or common shares, or the availability of ADSs or common shares for future sale will have on the market price of the ADSs prevailing from time to time. Sales of substantial amounts of ADSs or common shares in the public market, or the perception that future sales may occur, could adversely affect the prevailing market price of ADSs or the common shares.

TAXATION

ROC Taxation

The following discussion is the opinion of Lee and Li. The discussion describes the principal ROC tax consequences of the ownership and disposition of ADSs representing common shares to a non-resident individual or entity. It applies to you only if you are:

| • | an individual who is not a ROC citizen, who owns ADSs and who is not physically present in the ROC for 183 days or more during any calendar year; or
| • | a corporation or a non-corporate body that is organized under the laws of a jurisdiction other than the ROC for profit-making purposes and has no fixed place of business or other permanent establishment in the ROC.

You should also consult your tax advisors concerning the ROC tax consequences of owning ADSs.

Dividends

Dividends declared by us out of our retained earnings and distributed to you are subject to ROC withholding tax, currently at the rate of 20%, on the amount of the distribution in the case of cash dividends or on the par value of the common shares in the case of stock dividends. However, a 10% ROC retained earnings tax paid by us on our undistributed after-tax earnings, if any, would provide a credit up to 10% of the gross amount of any dividends declared out of such earnings that would reduce the 20% ROC tax imposed on these distributions.

Dividends paid by us out of our capital reserves are not subject to ROC withholding tax.

Capital Gains

Under ROC law, capital gains on share securities transactions are exempt from income tax.

Subscription Rights

Distributions of statutory subscription rights for common shares in compliance with ROC law are not subject to any ROC tax. Proceeds derived from sales of statutory subscription rights evidenced by securities are exempted from income tax but are subject to securities transaction tax at the rate of 0.3% of the gross amount received. Proceeds derived from sales of statutory subscription rights which are not evidenced by securities are subject to capital gains tax at the rate of:

| • | 35% of the gross amount received if you are a natural person; or
| • | 25% of the gross amount received if you are an entity that is not a natural person.

Subject to compliance with ROC law, we, at our sole discretion, can determine whether statutory subscription rights shall be evidenced by issuance of securities.

Securities Transaction Tax

A securities transaction tax, at the rate of 0.3% of the gross amount received, will be withheld upon a sale of common shares in the ROC. Transfers of ADSs are not subject to ROC securities transaction tax. Withdrawal of common shares from the deposit facility is not subject to ROC securities transaction tax.

108

##### Table of Contents

Estate and Gift Tax

ROC estate tax is payable on any property within the ROC of a deceased who is an individual, and ROC gift tax is payable on any property within the ROC donated by any such person. Estate tax is currently payable at rates ranging from 2% of the first NT$600,000 to 50% of amounts over NT$100,000,000. Gift tax is payable at rates ranging from 4% of the first NT$600,000 to 50% of amounts over NT$45,000,000. Under ROC estate and gift tax laws, common shares issued by ROC companies are deemed located in the ROC regardless of the location of the holder. It is unclear whether a holder of ADSs will be considered to hold common shares for this purpose since there is no authority directly indicating whether an ADR holder will be treated as owning the shares represented by the ADR. However, despite of this lack of direct authority, we are of the view that a holder of ADSs will not be subject to the ROC estate and gift tax because (1) the ADSs are not considered property within the ROC and (2) the transfer of ADSs is not deemed to be a transfer of the underlying common shares.

Tax Treaty

The ROC does not have an income tax treaty with the United States. On the other hand, the ROC has income tax treaties with Indonesia, Singapore, South Africa, Australia, Vietnam, New Zealand, Malaysia, Macedonia, Swaziland and Gambia, which may limit the rate of ROC withholding tax on dividends paid with respect to common shares of ROC companies. It is unclear whether if you hold ADSs, you will be considered to hold common shares for the purposes of these treaties. Accordingly, if you may otherwise be entitled to the benefits of the relevant income tax treaty, you should consult your tax advisors concerning your eligibility for the benefits with respect to the ADSs.

United States Federal Income Taxation

The following discussion is the opinion of Davis Polk & Wardwell. The discussion describes the material U.S. federal income tax consequences of the acquisition, ownership and disposition of ADSs to those U.S. holders described below. For these purposes, you are a U.S. holder if you are a beneficial owner of common shares that, for U.S. federal income tax purposes, is:

| • | a citizen or resident of the United States;
| • | a corporation or other entity taxable as a corporation organized under the laws of the United States or of any political subdivision of the United States; or
| • | an estate or trust the income of which is includable in gross income for U.S. federal income tax purposes regardless of its source.

This discussion only applies to ADSs that you purchase through this offering and only if you hold the ADSs as capital assets.

This discussion assumes that ASE Inc. will not be considered a passive foreign investment company. Please see our discussion of passive foreign investment company rules below.

Please note that this discussion does not address all of the tax consequences that may be relevant in light of your particular circumstances. In particular, it does not address all of the tax consequences that may be relevant to purchasers subject to special rules, including:

| • | persons subject to the alternative minimum tax;
| • | insurance companies;
| • | tax-exempt entities;
| • | dealers or traders in securities;
| • | financial institutions;

109

##### Table of Contents

| • | persons who hold or will hold common shares as part of an integrated investment, including a straddle, hedging or conversion transaction, comprised of common shares and one or more other positions for tax purposes;
| • | persons whose functional currency is not the U.S. dollar; or
| • | persons who own 10% or more of our voting stock.

This discussion is based on the Internal Revenue Code of 1986, Treasury Regulations, administrative announcements and judicial decisions currently in effect. These laws and regulations may change, possibly with retroactive effect. This discussion is also based in part on representations by the depositary and assumes that each obligation under the deposit agreement and any related agreement will be performed in accordance with its terms.

For U.S. federal income tax purposes, a U.S. holder of ADSs should be treated as the holder of the common shares represented by the ADSs. However, the U.S. Treasury has expressed concerns that parties to whom depositary shares are pre-released may be taking actions that are inconsistent with the claiming of foreign tax credits by the holders of ADSs. Accordingly, the analysis of the creditability of ROC taxes described below could be affected by future actions that may be taken by the U.S. Treasury.

Please consult your tax advisors with regard to the application of the U.S. federal income tax laws to ADSs as well as any tax consequences arising under the laws of any state, local or non-U.S. taxing jurisdictions.

Dividends

Any dividends you receive on ADSs, including the amount of any ROC taxes withheld thereon, reduced by any credit against the withholding tax on account of the 10% retained earnings tax imposed on ASE Inc., other than pro rata distributions of common shares to all shareholders including holders of ADSs, will constitute foreign source dividend income to the extent paid out of earnings and profits as calculated for U.S. federal income tax purposes. The amount you will be required to include in income for any dividend paid in NT dollars will be equal to the U.S. dollar value of the NT dollars paid, calculated by reference to the exchange rate in effect on the date the depositary receives the dividend. If you realize gain or loss on a sale or other disposition of NT dollars, it will be U.S. source ordinary income or loss. You will not be entitled to a dividends-received deduction for dividends you receive.

Subject to applicable limitations and restrictions, the ROC taxes withheld from dividend distributions, reduced by any credit against the withholding tax on account of the 10% retained earnings tax, will be eligible for credit against your U.S. federal income tax liabilities. The limitation on foreign taxes eligible for credit is calculated separately with respect to specific classes of income including, amongst others, “passive income”, “financial services income” and “general limitation income”. For this purpose, dividends paid with respect to the common shares will constitute “passive income” or, in the case of U.S. financial services providers may be, “financial services income”.

Pro rata distributions of common shares by a company to its shareholders, including holders of ADSs, will not be subject to U.S. federal income tax. Accordingly, these distributions will not give rise to U.S. federal income against which the ROC tax imposed on these distributions may be credited. Any ROC tax of this nature will only be creditable against a U.S. holder’s U.S. federal income tax liability with respect to income in the “general limitation income” class and not “passive income” or “financial services income”, subject to applicable limitations and restrictions.

110

##### Table of Contents

Capital Gains

You will recognize capital gain or loss for U.S. federal income tax purposes on the sale or exchange of ADSs in the same manner as you would on the sale or exchange of any other common shares held as capital assets. The gain or loss will be U.S. source income or loss. You should consult your own tax advisor about the treatment of capital gains, which may be taxed at lower rates than ordinary income for non-corporate taxpayers, and capital losses, the deductibility of which may be limited.

Deposits and withdrawals of common shares by a U.S. holder in exchange for ADSs will not result in realization of gain or loss for U.S. federal income tax purposes.

Passive Foreign Investment Company Rules

Based on management estimates and the available financial data, ASE Inc. does not expect to be a passive foreign investment company. In general, a foreign corporation is a passive foreign investment company for any taxable year in which (1) 75% or more of its gross income consists of passive income (such as dividends, interest, rents and royalties) or (2) 50% or more of the average quarterly value of its assets consists of assets that produce, or are held for the production of, passive income. The determination of whether ASE Inc. may be a passive foreign investment company will be based on the composition of its income and assets, as well as those of its subsidiaries and certain affiliates, from time to time. Since the composition of ASE Inc.’s income and assets will vary over time, there can be no assurance that it will not be considered a passive foreign investment company for any fiscal year. If ASE Inc. is a passive foreign investment company at any time that you own ADSs:

| • | You may be subject to additional taxes and interest charges on any gain realized on the disposition of the ADSs, as applicable, and on “excess distributions”. The additional taxes are assessed at the highest tax rate applicable for corporate or individual taxpayers for the relevant tax periods; and
| • | You will be subject to additional U.S. tax filing requirements for each year that you hold ADSs.

Please consult your tax advisors about the possibility that ASE Inc. may be a passive foreign investment company and the rules that would apply to you if it were.

Estate and Gift Tax

As discussed in “— ROC Taxation”, you might be required to pay ROC estate and gift tax. You should consult your tax advisor regarding the effect of these taxes.

UNDERWRITING

We and the underwriters named below have entered into an underwriting agreement with respect to the ADSs being offered. Subject to the conditions set forth in the underwriting agreement, each underwriter has severally agreed to purchase the number of ADSs indicated in the following table. Goldman Sachs (Asia) L.L.C. and Morgan Stanley & Co. Incorporated are the representatives of the underwriters.

ADSs sold by the underwriters to the public will initially be offered at the initial public offering price set forth on the cover of this prospectus. Any ADSs sold by the underwriters to securities dealers may be sold at a discount of up to US$ per ADS from the initial public offering price. Any such securities dealers may resell any ADSs purchased from the underwriters to certain other brokers or dealers at a discount of up to US$ per ADS from the initial public offering price. If all the ADSs are not sold at the initial public offering price, the representatives may change the offering price and the other selling items.

We have been advised by the underwriters that certain of the underwriters are expected to make offers and sales both inside and outside of the United States through their respective selling agents and that Barits Securities Corporation and FB Gemini Capital Limited are expected to make offers and sales outside of the United States.

We have entered into a 90-day lock-up agreement with the underwriters regarding: (1) our common shares and depositary receipts representing our common shares, including those held by our subsidiaries and controlled affiliates; (2) common shares of our subsidiaries and

controlled affiliates and depositary receipts representing those shares; and (3) securities that are substantially similar to such common shares and depositary receipts. We have also agreed to cause our subsidiaries and controlled affiliates to abide by the restrictions of the lock-up agreement. In addition, ASE Enterprises, our principal shareholder, and each of Jason C.S. Chang, Richard H.P. Chang, Chang Yao Hung-ying and Feng Mei-Jean have entered into a similar lock-up agreement with respect to our common shares, depositary receipts representing our common shares and securities that are substantially similar to our common shares or depositary receipts representing our common shares. See “Common Shares Eligible For Future Sale”.

Each underwriter has represented and agreed that (1) it has not offered or sold and prior to the date six months after the date of issue of the ADSs will not offer or sell any ADSs to persons in the United Kingdom, except to persons whose ordinary activities involve in them in acquiring, holding, managing or disposing of investments (as principal or agent) for the purposes of their businesses or otherwise in circumstances that have not resulted and will not result in an offer to the public in the United Kingdom within the meaning of the Public Offers of Securities Regulations 1995; (2) it has complied, and will comply with, all applicable provisions of the Financial Services Act 1986 of Great Britain with respect to anything done by it in relation to the ADSs in, from or otherwise involving the United Kingdom; and (3) it has only issued or passed on and will only issue or pass on in the United Kingdom any document received by it in connection with the issuance of the ADSs to a person who is of a kind described in Article 11(3) of the Financial Services Act 1986 (Investment Advertisements) (Exemptions) Order 1996 (as amended) of Great Britain or is a person to whom the document may lawfully be issued or passed on.

Each underwriter has acknowledged and agreed that the ADSs have not been registered under the Securities and Exchange Law of Japan and are not being offered or sold and may not be offered or sold, directly or indirectly, in Japan or to or for the account of any resident of Japan, except (1) pursuant to an exemption from the registration requirements of the Securities and Exchange Law of Japan and (2) in compliance with any other applicable requirements of Japanese law. As part of the offering, the underwriters may offer ADSs in Japan to a list of 49 offerees in accordance with the above provisions.

This prospectus has not been delivered for registration to the Registrar of Companies in Hong Kong and, accordingly, must not be issued, circulated or distributed in Hong Kong other than to persons whose ordinary business it is to buy or sell shares or debentures, whether as principal or agent, within the meaning of the Hong Kong Companies Ordinance, or in circumstances which do not constitute an offer to the public for the purposes of the Hong Kong Companies Ordinance. Unless permitted by the securities laws of Hong Kong, no person may issue or cause to be issued in Hong Kong this prospectus or any amendment or supplement hereto or other invitation, advertisement or document relating to the shares of ADSs to anyone other than a person whose business involves the acquisition and disposal, or holding, of securities whether as principal or agent.

This document has not been registered as a prospectus with the Registrar of Companies in Singapore, and the ADSs will be offered in Singapore pursuant to an exemption invoked under Section 106C and Section 106D of the Companies Act, Chapter 50 of Singapore, or the Singapore Companies Act. Accordingly, the ADSs may not be offered or sold, nor may this document or any other offering document or material relating to the ADSs be circulated or distributed, directly or indirectly, to the public or any member of the public in Singapore other than (1) to an institutional investor or other person specified in Section 106C of the Singapore Companies Act, (2) to a sophisticated investor, and in accordance with the conditions, specified in Section 106D of the Singapore Companies Act or (3) otherwise pursuant to, and in accordance with the conditions of, any other applicable provision of the Singapore Companies Act.

The securities may not be offered, sold, transferred or delivered in or from The Netherlands, as part of their initial distribution or as part of any re-offering, and neither this prospectus nor any other document in respect of the offering may be distributed or circulated in The Netherlands, other than to individuals or legal entities which include, but are not limited to, banks, brokers, dealers, institutional investors and undertakings with a treasury department, who or which trade or invest in securities in the conduct of a business or profession.

No action has been or will be taken in any jurisdiction other than the United States that would permit a public offering of the ADSs or the possession, circulation or distribution of this prospectus in any jurisdiction where action for that purpose is required. Accordingly, the ADSs may not be offered or sold, directly or indirectly, and neither this prospectus nor any other offering material or advertisements in connection with the ADSs may be distributed or published in or from any country or jurisdiction except under circumstances that will result in compliance with any applicable rules and regulations of any such country or jurisdiction.

Each underwriter has also represented and agreed that it has not offered or sold, and has agreed not to offer or sell any ADSs, directly or indirectly, in the ROC.

A prospectus in electronic format may be made available on the Web sites maintained by one or more underwriters or securities dealers. The representatives of the underwriters may agree to allocate a number of ADSs to the underwriters for sale to their online brokerage account holders. ADSs to be sold pursuant to an Internet distribution will be allocated by the representatives to the underwriters that may make Internet distributions on the same basis as other allocations. In addition, ADSs may be sold by the underwriters to securities dealers who resell ADSs to online brokerage account holders.

Application has been made for listing of the ADSs offered by this prospectus on the New York Stock Exchange under the temporary symbol “ASX Pr” for a period of three months and thereafter under the symbol “ASX”. In order to meet one of the requirements for listing the ADSs on the New York Stock Exchange, the underwriters have undertaken to sell lots of 100 or more ADSs to a minimum of 2,000 beneficial holders.

Before the offering, there has been no public market for the ADSs in the United States. The initial offering price of the ADSs will be determined based on, in addition to prevailing market conditions and the level of investor interest in the ADSs, the closing price of the common shares on the Taiwan Stock Exchange.

In connection with the offering, the underwriters may purchase and sell ADSs in the open market. These transactions may include short sales, stabilizing transactions and purchases to cover positions created by short sales. Short sales involve the sale by the underwriters of a greater number of ADSs than they are required to purchase in the offering. “Covered” short sales are sales made in an amount not greater than the underwriters’ option to purchase additional ADSs from ASE Inc.’s wholly-owned subsidiary in the offering. The underwriters may close out any covered short position by either exercising their option to purchase additional ADSs or purchasing additional ADSs in the open market. In determining the source of ADSs to close out the covered short position, the underwriters will consider, among other things, the price of ADSs available for purchase in the open market as compared to the price at which they may purchase ADSs through the over-allotment option. “Naked” short sales are any sales in excess of such option. The underwriters must close out any naked short position by purchasing ADSs in the open market. A naked short position is more likely to be created if the underwriters are concerned that there may be downward pressure on the price of ADSs in the open market after pricing that could adversely affect investors who purchase in the offering. Stabilizing transactions consist of various bids or purchases of ADSs made by the underwriters in the open market prior to the completion of the offering.

114

##### Table of Contents

The underwriters also may impose a penalty bid in the offering. This occurs when a particular underwriter repays to the underwriters for the same offering a portion of the underwriting discount received by it because the representatives have repurchased ADSs sold by or for the account of the underwriter in stabilizing or short covering transactions.

Purchases to cover a short position and stabilizing transactions may have the effect of preventing or retarding a decline in the market price of the ADSs, and together with the imposition of a penalty bid, may stabilize, maintain or otherwise affect the market price of the ADSs. As a result, the price of the ADSs may be higher than the price that otherwise might exist in the open market. If these activities are commenced, they may be discontinued at any time. These transactions may be effected on the New York Stock Exchange, in the over-the-counter market or otherwise.

We estimate that our share of the total expenses of the offering, excluding underwriting discounts and commissions, will be approximately US$1,500,000.

We have agreed to indemnify the several underwriters against liabilities, including liabilities under the Securities Act of 1933.

ENFORCEABILITY OF CIVIL LIABILITIES

We are a company limited by shares and incorporated under the ROC Company Law. Substantially all of our directors and executive officers, our supervisors and some of the experts named in this prospectus are residents of the ROC and a substantial portion of our assets and such persons are located in the ROC. As a result, it may not be possible for investors to effect service of process upon us or such persons within the United States, or to enforce against them judgments obtained in the United States courts, including those predicated upon the civil liability provisions of the federal securities laws of the United States. We have been advised by Lee and Li, our ROC counsel, that in their opinion any final judgment obtained against us in any court other than the courts of the ROC in connection with any legal suit or proceeding arising out of or relating to the ADSs will be enforced by the courts of the ROC without further review of the merits only if the court of the ROC in which enforcement is sought is satisfied that:

| • | the court rendering the judgment has jurisdiction over the subject matter according to the laws of the ROC;
| • | the judgment is not contrary to the public order or good morals of the ROC;
| • | if the judgment was rendered by default by the court rendering the judgment, we were served within the jurisdiction of the court or process was served on us with judicial assistance of the ROC; and
| • | judgments of the courts of the ROC are recognized and enforceable in the court rendering the judgment on a reciprocal basis.

A party seeking to enforce a foreign judgment in the ROC would be required to obtain foreign exchange approval from the Central Bank of China for the payment out of the ROC of any amounts recovered in connection with the judgment denominated in a currency other than NT dollars.

VALIDITY OF SECURITIES

The validity of the ADSs will be passed upon for ASE Inc. by Davis Polk & Wardwell, New York, New York, and for the underwriters by Sullivan & Cromwell, New York, New York. The validity of the common shares will be passed upon for ASE Inc. by Lee and Li, Taipei, Taiwan, ROC.

INDEPENDENT AUDITORS’ REPORT

The Board of Directors and Shareholders

Advanced Semiconductor Engineering, Inc.

We have audited the accompanying consolidated balance sheets of Advanced Semiconductor Engineering, Inc., a corporation incorporated under the laws of the Republic of China, and its consolidated subsidiaries (the “Corporation”) as of December 31, 1998 and 1999 and the related consolidated statements of income, changes in shareholders’ equity and cash flows for the years ended December 31, 1997, 1998 and 1999, all expressed in New Taiwan dollars. These financial statements are the responsibility of the Corporation’s management. Our responsibility is to express an opinion on these financial statements based on our audits.

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

In our opinion, the consolidated financial statements referred to above present fairly, in all material respects, the financial position of the Corporation as of December 31, 1998 and 1999, and the results of their operations and their cash flows for the years ended December 31, 1997, 1998 and 1999, in conformity with the regulations governing the preparation of financial statements of public companies and generally accepted accounting principles in the Republic of China.

Certain accounting practices of the Corporation used in preparing the accompanying financial statements conform with generally accepted accounting principles in the Republic of China, but do not conform with generally accepted accounting principles in the United States of America (“US GAAP”). A description of the differences and the adjustments required to conform the financial statements to US GAAP are set forth in Note 27.

The consolidated financial statements of the Corporation as of and for the six months ended June 30, 1999 and 2000, which are presented solely for comparative purposes, were not audited by independent auditors.

2. Significant Accounting Policies

The accompanying financial statements have been prepared in conformity with regulations governing the preparation of financial statements of public companies, and generally accepted accounting principles in the ROC (“ROC GAAP”). Significant accounting polices are summarized as follows:

Presentation of financial statements

For the purpose of the proposed offering of depositary shares, the accompanying balance sheets are presented for two year-ends as at December 31, 1998 and 1999, and the accompanying statements of income, changes in shareholders’ equity and cash flows are presented for three years ended December 31, 1997, 1998 and 1999. Unaudited interim information as at and for the six months ended June 30, 1999 and 2000 is also presented for comparative purposes.

Unless otherwise stated, amounts presented are in thousands of New Taiwan dollars (NT$) or U.S. dollars (US$).

Consolidation

The consolidated financial statements include the accounts of ASE and all of the aforementioned companies (hereinafter, individually or collectively referred to as “the Corporation”).

The consolidated method used by the Corporation to consolidate the statement of income of ISE Labs for the year ended December 31, 1999, ISE Lab’s full year 1999 net revenues, cost of revenues and operating expenses are included in the Corporation’s consolidated statements of

F-17

(Amounts in Thousands of New Taiwan Dollars, Unless Otherwise Stated)

income. The pre-acquisition income of ISE Labs for the year ended December 31, 1999 (from January 1 to May 4, 1999) is then subtracted from the Corporation’s net income for 1999.

The statements of income for both ASE Chung Li and ASE (Korea) Inc. (“ASE Korea”) (representing the acquirees from acquisitions of Motorola SPS Businesses) are consolidated since the date of acquisitions due to the change of business type after acquisition in ASE Chung Li and ASE Korea for the accounting of silicon wafers from previous purchase and sale transaction to customers’ consignments (see accounting policy for inventories).

The accounts of ASE Material for 1999 are consolidated because ASE in effect controls ASE Material in the following manner. First, two of the five board members of ASE Material are appointed by ASE and one board member is appointed by ASE Test, Inc., a consolidated subsidiary of ASE. Second, Mr. Jason Chang, the Chairman of ASE, also serves as the Chairman of ASE Material. Third, ASE appoints ASE Material’s sole Supervisor, whose duty under the ROC Company Law is to monitor ASE Material’s business and financial condition. Finally, Mr. Jason Chang has committed to vote his shares of ASE Material, which represent a 11.4% ownership interest in ASE Material, in concert with ASE.

All intercompany accounts and transactions have been eliminated and minority shareholders’ interests in the equity and earnings of the subsidiaries are presented separately in the financial statements. The differences between the costs of investments and the proportionate equity in each subsidiary when the stocks were acquired are recorded as consolidated credits (debits) and are amortized on the straight-line method over ten years.

Use of estimates

The preparation of financial statements in conformity with ROC GAAP and the generally accepted accounting principles in the United States (“US GAAP”) requires management to make estimates and assumptions that affect certain reported amounts and disclosures. Actual results could differ from those estimates.

Short-term investments

Marketable securities are carried at cost less allowance for decline in market value.

Allowances for doubtful accounts

Allowance for doubtful accounts is provided based on an evaluation of the collectibility of receivables.

Inventories

Inventories are stated at the lower of weighted average cost or market value. Unbilled processing charges incurred (included in finished goods and work in process) are stated at actual cost. Market value represents net realizable value for finished goods and work in process, and replacement costs for raw materials, supplies and spare parts.

Materials received from customers for processing, mainly silicon wafers, are excluded from inventories.

(Amounts in Thousands of New Taiwan Dollars, Unless Otherwise Stated)

Long-term investments in shares of stock

Long-term investments of which ASE owns at least 20% of the outstanding voting shares and where ASE exercises significant influence on the investee companies’ operations are accounted for by the equity method. Under the equity method, the investments are initially carried at cost and subsequently adjusted for ASE’s proportionate share in the net earnings or losses of the investee companies. Such proportionate share in earnings or losses are recognized as investment income or losses while any cash dividends received are reflected as a reduction in the carrying value of the investments. The goodwill representing the excess of the investment costs over ASE’s proportionate equity in the net assets of the investees at the time of investments or at the time the equity method of accounting is first applied to a particular investment, is amortized over ten years. Changes in ASE’s ownership percentage of investees accounted for by equity method are accounted for as adjustments of long-term investments and capital surplus. The writedown of carrying value of long-term investments has been taken on the basis of the discounted cash flows expected to be realized in the future.

Other long-term investments (including ASE common shares) in shares of stock are carried at cost. An allowance for decline in value is made for any permanent impairment in the carrying value of the investments and such decline in value is charged to current income. Cash dividends received are recognized as income. The sales of ASE stocks are reflected as gain from sale of long-term investment in the statement of income.

Unrealized profits or losses arising from transactions with equity investees or between equity investees are offset against investment income or loss from long-term investments, based on the percentage of ownership.

Long-term investments in bonds

Bond securities being held to maturity are stated at amortized cost.

Properties

Properties, except leased equipment, are stated at cost. Equipment held under capital lease and related obligations are stated at the lower of the fair value of the equipment at the beginning of the lease period or the present value of the total rental payments and the purchase price at the end of the lease period. Major renewals and improvements are capitalized, while maintenance and repairs are expensed currently.

Depreciation is provided on the straight-line method over estimated service lives which range as follows: land improvements, 20 years; long leasehold land, 60 years (lease period); buildings and improvements, 3 to 40 years; machinery and equipment, 3 to 8 years; furniture and fixtures, 5 to 10 years; transportation equipment, 3 to 10 years; and leased assets and leasehold improvements, 3 to 10 years. In the event that an asset depreciated to its residual value is deemed to have a continual useful life to the company, the residual value is depreciated over the remaining life, not to exceed 2 years.

When properties are retired or disposed of, their costs and accumulated depreciation are removed from the accounts and any loss is charged to income; any gain is credited to income and, after deducting applicable income tax, is transferred to capital surplus.

ADVANCED SEMICONDUCTOR ENGINEERING, INC. AND SUBSIDIARIES

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS — (Continued)

(Amounts in Thousands of New Taiwan Dollars, Unless Otherwise Stated)

Deferred charges

Deferred charges are amortized on the straight-line method as follows: tooling, 2 years; issuance costs of convertible bonds, 5 years; telecommunications, electrical and computer network systems, 5 years; and others, 2 to 5 years.

Consolidated debits

The consolidated debits as shown in the balance sheet representing goodwill arising from the excess of the acquisition costs of investments over ASE’s proportionate equity in the net assets of the consolidated subsidiaries at the time of acquisitions or investments, are amortized on the straight-line method over 10 years.

Revenue recognition

Revenue from the sale of semiconductor and computer products and testing services is recognized upon shipment of the products or completion of the services, with a provision for estimated returns and allowances recorded at the time of recognition of revenue.

Income tax

Tax effects of deductible temporary differences and unused tax credits are recognized as deferred income tax assets, while those of taxable temporary differences are recognized as deferred income tax liabilities. Valuation allowance is provided for deferred income tax assets based on the estimated realizability.

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

Income taxes on undistributed earnings (10%) generated in 1998 and onwards for consolidated entities in the ROC are recorded as expense in the following year when the shareholders have resolved that the earnings shall be retained.

Pension cost

Pension cost is recorded based on actuarial calculations.

Convertible bonds

Conversion of convertible bonds into common shares is accounted for by book value method. Under this method, unamortized bond issuance cost, accrued interest no longer payable and the carrying value of the bond are written off. In addition, common shares are recorded at par value of the shares issued and the excess is recorded as capital surplus.

Foreign currency transactions and translation of foreign currency financial statements

ASE and its subsidiaries maintain their accounts in the currency of their respective countries of incorporation (local currencies) and functional currencies.

Foreign currency transactions, other than foreign currency forward exchange contracts, are recorded in the local currencies at the rates of exchange in effect when the transactions occur. Gains or losses resulting from the application of different foreign exchange rates when foreign currency assets and liabilities are settled, are credited or charged to income in the year of

F-20

##### Table of Contents

ADVANCED SEMICONDUCTOR ENGINEERING, INC. AND SUBSIDIARIES

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS — (Continued)

(Amounts in Thousands of New Taiwan Dollars, Unless Otherwise Stated)

settlement. Year-end balances of foreign currency assets and liabilities are restated based on prevailing exchange rates and the resulting differences are credited or charged to income.

The financial statements of the foreign subsidiaries are translated into New Taiwan dollars at the following rates: assets and liabilities, current rate; and income and expenses, average exchange rate during the year. The net resulting translation adjustment is reported as a separate component of shareholders’ equity.

Derivative financial instruments

Premiums or discounts on foreign currency forward exchange contracts which hedge foreign currency assets or liabilities arising from the difference between the forward rate and the spot rate at the date of each contract are deferred and amortized over the contract period. At year end, the balances of the forward exchange receivables or payables are restated based on prevailing exchange rates and the resulting gain or loss is credited or charged to income. Any exchange gain or loss when the contract is settled is also credited or charged to income. The difference between receivable and payable balances arising from forward exchange contracts is accounted for as either current asset or current liability.

Written option contracts to purchase foreign currencies entered into for hedging purposes are not recorded as assets or liabilities on the contract dates. Gains or losses upon settlement are credited or charged to income. Amounts received or paid are amortized over each contract period. The outstanding written option contracts are marked to market with charges to income.

Interest rate swap agreements to limit the impact of the variable interest rate of certain long-term debt are not recorded as assets or liabilities on the contract date. The variable rates on swaps are based primarily on U.S. dollar LIBOR. The differential between fixed and variable rates to be paid or received on swaps is accrued as interest rates change in accordance with the agreements and is included in current interest expense.

Earnings per share (“EPS”) and earnings per equivalent GDS and ADS

Common shares of ASE’s convertible bonds are not considered in the calculation of primary and fully diluted EPS because they have anti-dilutive effect. Common share equivalents of the employees’ stock options of ASE Test are included in the EPS calculation (See Note 20).

Earnings per equivalent global depositary share (“GDS”) and pro forma equivalent American depositary share (“ADS”) are calculated by multiplying earnings per share by five (each of the GDS and ADS represents five common shares).

Set forth below is information on the long-term bonds payable:

A. Convertible bonds — US$200 million (NT$6,160 million)

In November 1997, ASE issued bonds, consisting of 200 units with face value of US$1 million (NT$30.8 million) each, with zero coupon, due November 2002. The bonds bear an implicit interest rate of 6.372%.

Starting from December 1997 through October 2002, bondholders may convert the bonds into common shares at the specified conversion price. The conversion rate was based on the current market price at the time of sale. As of June 30, 2000, 355,100 common shares were issued as a result of the conversion of such bonds, resulting in capital surplus of NT$32,102 (US$1,042). As of June 30, 2000, the outstanding convertible bonds aggregated US$199 million (NT$6,129 million).

On or at any time after October 14, 2000, ASE may redeem the bonds at the redemption price if:

| a. | (i) the closing price of the common shares for a period of 30 consecutive trading days is higher than 140% of the conversion price (NT$81 per share as at June 30, 2000) in effect on each such trading day and (ii) the closing price of the common shares translated into U.S. dollars at the prevailing rate for a period of 30 consecutive trading days is higher than 140% of the conversion price then in effect translated into U.S. dollars at the rate of NT$28.62 = US$1.00; or

| b. | at least 95% of the bonds have already been converted, redeemed, or purchased and cancelled.

In addition, ASE may, if the applicable tax law is unfavorably changed, redeem at any time all, but not some, of the bonds.

On September 5, 1997, ASE entered into a firm commitment subscription agreement with SBC Warburg Securities Pte. Ltd. (“SBC Warburg”) for the sale by ASE to SBC Warburg of US$200 million Zero Coupon Convertible Bonds due 2002 (the “Convertible Bonds”). The closing of the sale of the Convertible Bonds was initially scheduled to occur on October 6, 1997. Due to the adverse market conditions prevailing during this period of time as a result of the Asian financial crisis, however, SBC Warburg requested that the closing date for the sale of the Convertible Bonds be extended.

During the extension period (the “Extension Period”), SBC Warburg decided to market the Convertible Bonds to potential investors as two separate instruments by repackaging them into: (1) a debt portion consisting of US$200 million callable floating rate notes which are secured by the

F-29

##### Table of Contents

ADVANCED SEMICONDUCTOR ENGINEERING, INC. AND SUBSIDIARIES

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS — (Continued)

(Amounts in Thousands of New Taiwan Dollars, Unless Otherwise Stated)

Convertible Bonds (the “FRNs”) and (2) an equity portion consisting of options to purchase the Convertible Bonds (the “Call Options”). SBC Warburg was able to obtain commitments for the entire issue of the FRNs but, as a result of the adverse market conditions described above, was able to obtain commitments for only a portion of the Call Options. As a result, Swiss Bank Corporation (“SBC”), an affiliate of SBC Warburg, approached a number of large institutional investors, including J&R Holding Limited (“J&R Holding”), a consolidated subsidiary of ASE, with a proposal to sell a portion of the Call Options. Subsequently, J&R Holding entered into two agreements with SBC to purchase options on a portion of the Convertible Bonds.

Under the first agreement with SBC, J&R Holding is required to make four cash payments to SBC on November 4, 1998, 1999, 2000 and 2001 as long as the Call Options remain unexercised and outstanding. In return, J&R Holding has the right to call the Convertible Bonds at any time during the period from November 1998 through November 2002. The exercise price of the Call Options is equal to the accreted carrying value of the Convertible Bonds as shown on the Corporation’s balance sheet at the date exercised. Pursuant to the second agreement, SBC paid US$200,000 to J&R Holding. In return, SBC has the right to sell a portion of the Call Options to J&R Holding at any time between November 4, 1997 and November 1, 1998. In any event, J&R Holding was required under the automatic exercise provision of this agreement to purchase the Call Options upon the expiration of the agreement on November 1, 1998.

The closing of the sale of the Convertible Bonds eventually took place on November 4, 1997. Upon the closing of the sale of the Convertible Bonds, SBC Warburg immediately resold the Convertible Bonds to a subsidiary of SBC Warburg. Such subsidiary in turn repackaged the Convertible Bonds into the FRNs and the Call Options for resale to the investors that had indicated an interest in purchasing the FRNs and/or the Call Options during the Extension Period. The closing of the sale of the FRNs and the Call Options took place on November 5, 1997.

SBC Warburg and its subsidiary have entered into a swap transaction, which stipulated that SBC Warburg will pay the interest on the FRNs interest (aggregating US$80 million (NT$2,464 million)) on the subsidiary’s behalf. The subsidiary will repay the interest to SBC Warburg at the maturity date of the Convertible Bonds. ASE has contracted with certain banks to issue letters of credit for US$73,676 (NT$2,269,221) to SBC Warburg to guarantee the interest payment obligation of the subsidiary. Under the contract with these banks, ASE may not, among other things, change its scope of operations and is required to maintain certain financial ratios.

B. Foreign convertible bonds – US$110 million (NT$3,388 million)

In June 1999, ASE Test (the “Guarantor”), in connection with the acquisitions of ISE Labs and the Motorola SPS Businesses, issued US$160 million (NT$4,928 million) of 1% guaranteed convertible notes (the “Convertible Notes”) due July 1, 2004 through its subsidiary, ASE Test Finance Limited (the “Issuer”). ASE subscribed to US$50 million (NT$1,540 million) of the Convertible Notes and, accordingly, the net balance of US$110 million (NT$3,388 million) is shown in the accompanying balance sheet.

The holders of the Convertible Notes are entitled to convert the Convertible Notes into ASE Test’s ordinary shares at the specified conversion price at any time after December 29, 1999 and before or on July 1, 2004.

The Convertible Notes may be redeemed under the following circumstances:

| a. Redemption for taxation reasons:

| If the applicable tax law or treaty is unfavorably revised, the Issuer or ASE Test may redeem the Convertible Notes in whole at the early redemption price, at any time upon giving written notice not less than 30 days and not more than 60 days to the holders.

| b. Redemption at the option of the Issuer:

| On or at any time after July 1, 2002, the Issuer may redeem all or a part of the Bonds at the early redemption price.

As of June 30, 2000, Convertible Notes with an aggregate principal amount of US$110 have been converted into ordinary shares of ASE Test.

comply with the related regulations and the deposit agreement, which stipulate, among other things, that the GDS holders can, through Citicorp Financial Services Limited, as nominee holder: (a) exercise their voting rights; (b) sell their GDSs; and (c) receive dividends declared and subscribe to the issuance of new shares.

Under the ROC Company Law, capital surplus can only be used to offset a deficit or be transferred to capital. Under relevant regulations, the paid-in capital in excess of par value can be transferred to capital only once a year and is subject to a specified limit.

ASE’s Articles of Incorporation provide that the annual net income shall be appropriated as follows:

| a. gain on disposal of properties, less applicable income tax, as capital surplus;
| b. offset against deficit, if any;
| c. 10% of the remainder as legal reserve, until the accumulated amount equals paid-in capital;
| d. an amount (Note 6) equal to the income from long-term investments in shares of stock accounted for by equity method, excluding cash dividends, as special reserve;
| e. not more than 2% of the remainder as compensation to directors and supervisors;
| f. 5% to 7% of the remainder as bonus to employees, of which 5% will be distributed in shares based on the employee stock bonus plan and the excess to be distributed to specific employees as decided by the board of directors; and
| g. the remainder, as dividends to shareholders.

The aforementioned appropriations shall be approved by the shareholders in the following year and given effect to in the financial statements of such year.

Under the ROC Company Law, the aforementioned legal reserve may be used to offset a deficit. Also, when the reserve has reached 50% of capital, up to 50% thereof may be transferred to capital.

Under the Integrated Income Tax System, which became effective on January 1, 1998, non-corporate resident shareholders are allowed a tax credit for the income tax paid or payable by ASE on earnings generated in 1998 and onwards. An Imputation Credit Account (“ICA”) is maintained by ASE for such income tax and the tax credit allocated to each shareholder. The maximum credit available for allocation to each shareholder cannot exceed the balance shown in the ICA on the date of distribution of dividends.

As of June 30, 2000, the creditable taxes aggregated NT$278,309 (US$9,036). The actual percentage for the distribution of 1998 and 1999 net income was 8.82% and 4.74%, respectively.

As of June 30, 2000, the unappropriated earnings prior to 1998 (the year that the Integrated Income Tax System became effective) amounted to NT$17,644 (US$573).

In assessing the realizability of deferred tax assets, ASE considered its future taxable earnings and expected timing for the reversal of temporary differences. The valuation allowance is provided to reduce the gross deferred tax assets to an amount which ASE believes will more likely be realized. Deferred tax assets and liabilities are classified in the consolidated balance sheet based on the classification of the related assets or liabilities or the expected timing of the reversal of temporary differences.

The gain on sales of the ASE Test’s ordinary shares in 1997 and 1999, as discussed in Note 16, was considered as a permanent difference because management decided to re-invest and not to distribute the gain and, accordingly, no deferred tax liability was recognized.

d. As of December 31, 1999 and June 30, 2000, unused tax credits of ROC subsidiaries which can be utilized to offset their future income tax are set forth below:

The losses arising from such contracts based on mark–to–market valuation were approximately NT$465,817, NT$336,101 (US$10,912) and NT$2,864 (US$93) in 1998, 1999 and the six months ended June 30, 2000, respectively.

d. Transaction risk

1) Credit risk

ASE is exposed to credit risk in the event of non-performance of the counterparties to forward contracts on maturity. In order to manage this risk, ASE transacts only with financial institutions with good credit ratings. As a result, no material losses resulting from counterparty defaults are anticipated.

2) Market risk

ASE entered into European option and interest rate swap contracts to hedge the effects of foreign currency fluctuations on net assets or net liabilities, and the fluctuations in interest rates. Hence, the impact of market risk was reduced. ASE has no outstanding derivative contracts to hedge exposure to existing foreign currency assets and liabilities as of December 31, 1999.

3) Liquidation risk and cash-flow risk

ASE entered into European option contracts to hedge its exposure to the effect of exchange rate fluctuations on net assets or net liabilities. At the maturity of these contracts, ASE has enough operating capital to meet cash requirements, so there is no fund raising risk. Therefore, ASE believes there are no significant exposures to liquidation risk and cash flow risk.

The carrying values of cash, notes receivable, accounts receivable, short-term borrowings, C/P and B/A payable, and notes and accounts payable approximate fair value because of the short maturity of these instruments. The fair value of short-term and long-term investments are determined based on market values or net equity values. The fair value of long-term liabilities is determined based on the estimated present value of future cash flow using the interest rates of similar long-term debt instruments which ASE is able to obtain as the discount rate. Fair value of long-term debt is its carrying value because floating interest rates are applied.

26. ACQUISITIONS

In May 1999, ASE Test acquired 70% equity of ISE Labs, which is engaged in the testing and packaging of semiconductors. The purchase cost, including transaction costs, was approximately US$100.1 million (NT$3,083.1 million), which was paid in May 1999.

In July 1999, ASE and ASE Test purchased 70% and 30%, respectively, of the interest of the Motorola SPS Businesses. The purchase cost was approximately US$350.1 million (NT$10,783.1 million). As of December 31, 1999, US$176.2 million (NT$5,426.96 million) has been paid and the balance of US$173.9 million (NT$5,356.1 million), plus interest (commencing as of the acquisition date — July 1999) is payable, $70.0 million of which is subject to target sales volumes being met for the Motorola SPS Businesses in Chung Li, Taiwan, based on specified payment dates within four years. ASE believes the contingent payments of US$70 million are determinable beyond a reasonable doubt. As of December 31, 1999, ASE has provided guaranteed letters of credit of US$173,876 (NT$5,355,381) to Motorola for the future payable. Both acquirees currently provide packaging and testing of semiconductors. A portion of the purchase price was financed through a convertible notes offering completed on June 29, 1999 by ASE Test Finance Limited and fully and unconditionally guaranteed by ASE Test (see Note 13).

Future payments for investments in Motorola as of December 31, 1999 are as follows:

|  | NT$ |  | US$
Within the following year |  | 1,490,599 |  | 48,396
Within the second year |  | 1,679,176 |  | 54,519
Within the third year |  | 1,679,176 |  | 54,519
Within the fourth year |  | 625,829 |  | 20,319
|  | 5,474,780 |  | 177,753

The acquisitions of the Motorola SPS Businesses and ISE Labs were accounted for by the purchase method. Assets acquired and liabilities assumed have been recorded at their estimated fair values as of the acquisition dates. The purchase prices exceeded the fair value of the net tangible assets by about US$81.9 million (NT$2,522.5 million) for Motorola SPS Businesses and

27. Summary of Significant Differences Between Accounting Principles Followed by the Corporation and Generally Accepted Accounting Principles in the United States

The accompanying financial statements have been prepared in accordance with generally accepted accounting principles in the Republic of China (“ROC GAAP”), which differ in the

F-51

##### Table of Contents

ADVANCED SEMICONDUCTOR ENGINEERING, INC. AND SUBSIDIARIES

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS — (Continued)

(Amounts in Thousands of New Taiwan Dollars, Unless Otherwise Stated)

following respects from generally accepted accounting principles in the United States (“US GAAP”):

a. Pension benefits

| U.S. Financial Accounting Standards (FAS) 87, “Accounting for Pensions”, was effective no later than the beginning of the first period for which a US GAAP reconciliation is required. A portion of the unrecognized net transition obligation at the adoption date is to be allocated directly to equity. The adoption date of ASE for US FAS 87 is the beginning of 1987. ROC SFAS 18, which is substantially similar to US FAS 87, was effective in 1996 for listed companies in Taiwan. Therefore, pension expenses due to different adoption dates is adjusted.

b. Short-term investments

| Under ROC GAAP, marketable equity securities are carried at the lower of aggregate cost or market value, and debt securities at cost. Under US FAS 115, “Accounting for Certain Investments in Debt and Equity Securities”, except for debt securities classified as “held-to-maturity securities”, investments in debt and equity securities, other than those recorded on the equity method, should be stated at fair value.
| All of the Corporation’s short-term investments are classified as trading securities under US GAAP, with gains and losses recognized currently in income. The unrealized holding gain included in earnings under US GAAP were NT$12,584 (US$408) in 1999. All of the Corporation’s short-term investments in mutual funds, stock and convertible debt are bought and held principally for the purpose of selling them in the near term.

c. Bonuses to employees, directors and supervisors

| According to ROC regulations and the Articles of Incorporation of ASE, a portion of distributable earnings should be set aside as bonuses to employees, directors and supervisors. Bonuses to directors and supervisors are always paid in cash. However, bonuses to employees may be granted in cash or stock or both. All of these appropriations, including stock bonuses which are valued at par value of NT$10, are charged against retained earnings under ROC GAAP, after such appropriations are formally approved by the board of directors and resolved by the shareholders in the following year. Under US GAAP, such bonuses are charged to income currently in the year earned. Stock issued as part of these bonuses is recorded at fair market value. Since the amount and form of such bonuses are not finally determinable until the board of directors meeting in the subsequent year, the total amount of the aforementioned bonuses (“regular bonuses”) is initially accrued based on the management’s estimate regarding the amount to be paid based on ASE’s Articles of Incorporation. Any difference between the initially accrued amount and the fair market value of the bonuses settled by the issuance of shares is recognized in the year of approval by the board of directors. The management estimates that the regular annual employee bonuses, including cash and stock, will approximate three to four months’ salaries and wages.
| Aside from the aforementioned regular bonus plan, ASE decided to grant a special stock bonus to employees in 1997. Employees who received the special stock bonus are required to continue working for ASE for an additional three years. Accordingly, the amount of special stock bonuses is being allocated over three years as special compensation expenses in the statement of income.

d. Treasury stock

F-52

##### Table of Contents

ADVANCED SEMICONDUCTOR ENGINEERING, INC. AND SUBSIDIARIES

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS — (Continued)

(Amounts in Thousands of New Taiwan Dollars, Unless Otherwise Stated)

| Under US GAAP, when a subsidiary holds its parent’s stock as investments, the stock should be treated as treasury stock and is presented in the consolidated balance sheet as a deduction to shareholders’ equity. The capital gain (loss) from sales of treasury stock is added to or deducted from the balance of treasury stock. Under ROC GAAP, such treatment is not required and, as a result, the investment in ASE common shares are presented in long-term investment in the balance sheets and capital gain (loss) from sale of treasury stock is recognized and included in the statement of income.

e. Depreciation of buildings

| Under ROC GAAP, the estimated life of a building can be as long as 40 years based on ROC practices. For US GAAP purpose, an assessment for useful lives of buildings is estimated to be 25 years.

f. Excess of book value on transfer of buildings between related parties

| ASE Test, Inc., a consolidated subsidiary, purchased buildings and facilities from another consolidated subsidiary, ASE Technologies, in 1997. The actual costs purchased from ASE Technologies were based on market value. Such additional payment for the excess of book value of NT$17,667 was capitalized by ASE Test, Inc. as allowed under ROC GAAP. Under US GAAP, transfers of assets from related parties should not be recorded by the transferee at stepped-up values.

g. Gain on sales of subsidiary’s stock

| The carrying value of stock investments in ASE Test by J&R Holding under ROC GAAP is different from that under US GAAP mainly due to the differences in accounting for bonuses to employees, directors and supervisors. Since parts of such stock investments were sold in 1997 and 1999, the disposal gain (loss) under US GAAP was different from that under ROC GAAP as a result of the difference in carrying values.

h. Effects of US GAAP adjustments on equity long-term investment

| The carrying values of equity-basis investments and the investment income (loss) accounted for by the equity method in HCDC, HCKC and USI are reflected in the financial statements under ROC GAAP. The financial statements of these equity investees under ROC GAAP are different from the financial statements had those financial statements been prepared under US GAAP mainly due to the differences in accounting for bonuses to employees, directors and supervisors and depreciation of buildings. Therefore, the investment income (loss) has been adjusted to reflect the differences between ROC and US GAAP in the investees’ financial statements.

i. Impairment of long-lived assets

| U.S. FAS 121 requires entities to perform separate calculations for assets to be held and used to determine whether recognition of an impairment loss is required, and, if so, to measure the impairment. If the sum of expected future cash flows, undiscounted and without interest charges, is less than an asset’s carrying value, an impairment loss is recognized; if the sum of the expected future cash flows is greater than an asset’s carrying value, an impairment loss cannot be recognized. Measurement of an impairment loss is based on the fair value of the asset. U.S. FAS 121 also generally requires that long-lived assets and certain identifiable intangibles to be disposed of should be reported at the lower of the carrying value or fair value less cost to sell. Based on an assessment by ASE of the

F-53

(Amounts in Thousands of New Taiwan Dollars, Unless Otherwise Stated)

| potential impact of U.S. FAS 121, there is no impairment loss as of December 31, 1999 for ASE.

28. Additional Disclosures Required by US GAAP

ASE is required by SEC Staff Accounting Bulletin No. 74, to disclose the impact recently issued accounting standards will have on its financial statements when adopted in a future period, as well as make certain disclosures about recently issued accounting standards.

In June 1998, the Financial Accounting Standards Board issued Statement of Financial Accounting Standards No. 133 (“SFAS 133”), accounting for derivative instruments and hedging activities.

ASE has not yet quantified the impacts of adopting SFAS 133 on the financial statements and has not determined the timing of or method of adoption of SFAS 133. However, the SFAS 133 could increase volatility in earnings and other comprehensive income. The adoption of SFAS 133 will not be effective until 2001.

FAS 123, “Stock-Based Compensation” (“FAS 123”), effective in 1996, establishes accounting and disclosure requirements using a fair value-based method of accounting for stock-based employee compensation plans. Under FAS 123, ASE Test has elected to continue using the intrinsic value-based method and provide pro forma disclosures of net income and earnings per share as if the fair value accounting provisions of this statement had been adopted.

ASE has computed for pro forma disclosure purposes the fair value of each option grant, as defined by FAS 123, using the Black-Scholes option pricing model with the following assumptions:

|  | Pre-IPO Plan |  | 1996 Option Plan |  | 1997 Option Plan |  | 1998 Option Plan
Risk free interest rate |  |  | 5.41 | % |  |  | 5.47-5.76 | % |  |  | 4.29-5.76 | % |  |  | 4.56-5.76 | %
Expected dividend yield |  |  | 0 | % |  |  | 0 | % |  |  | 0 | % |  |  | 0 | %
Expected lives |  |  | 1.5 years |  |  |  | 3.6-4 years |  |  |  | 3.4-3.8 years |  |  |  | 3.4-3.8 years |

For purposes of pro forma disclosure, the estimated fair value of the options are amortized to expense over the option rights vesting periods. Had ASE Test recorded compensation costs based on the estimated grant date fair value, as defined by FAS 123, ASE’s net income under US GAAP would have been reduced to the pro forma amounts below.

Comprehensive Income |  |  | 396,704 |  |  |  | 4,467,344 |  |  |  | 145,044 |

f. Consolidation

The 1999 net revenues, cost of revenues and operating expenses of ISE Labs before the date of acquisition in the amounts of NT$736,765 (US$23,921), NT$475,250 (US$15,430) and NT$117,880 (US$3,827), respectively, were consolidated in the 1999 consolidated financial statements. The net revenues for the pre-acquisition period only represented 2% of the ASE’s consolidated net revenues in 1999 and such presentation has no impact on the 1999 consolidated net income and shareholders’ equity under US GAAP. If the results of ISE Labs were consolidated from the date of acquisition, the net revenues, gross profit and income from operation of 1999 consolidated statement of income will be NT$31,872,796 (US$1,034,831), NT$8,388,480 (US$272,353) and NT$4,704,924 (US$152,757).

29. Subsequent Events

In January 2000, ASE Chung Li and HCDC entered into an agreement for the development of buildings on land currently owned by ASE Chung Li. HCDC will bear all costs relating to the development. Following development, floor space in the completed buildings will be sold by HCDC at prices to be negotiated between HCDC and the buyers. ASE Chung Li and its affiliates will have priority in the purchase of that floor space. In the event that floor space is sold to persons other than ASE Chung Li, ASE Chung Li will receive 25% of the purchase price. The first phase of the development project is the construction of a building with aggregate floor space of approximately 800,000 square feet, which is expected to be completed in the fourth quarter of 2000. The total value of the first phase of the project, including land and the completed building, is estimated to be NT$2.0 billion.

NOTES TO COMBINED FINANCIAL STATEMENTS

(1) Organization, Principal Activities and Basis of Presentation

On July 4, 1999, ASE Test Limited and Advanced Semiconductor Engineering, Inc. (“the ASE Group”) purchased Motorola, Inc.’s Semiconductor Products Sector’s (“SPS”) businesses in Taiwan and South Korea. The acquisition consisted of substantially all of the assets of Motorola’s SPS facility in Chung Li, Taiwan and 100% of the common stock of Motorola Korea Ltd. Substantially all of the assets and liabilities included in Motorola Korea Ltd. related to the SPS business. The assets and liabilities of the SPS business in Taiwan were included in Motorola Electronics Taiwan Ltd. Prior to the acquisition, both Motorola Korea Ltd. and Motorola Electronics Taiwan Ltd. were wholly-owned subsidiaries of Motorola, Inc.

Basis of presentation

The combined financial statements reflect the combined financial condition, results of operations and cash flows of the SPS businesses under common control in a manner similar to a pooling of interests. Accordingly, the combined financial statements have been prepared on the basis of historical costs and as if the business activities of the SPS businesses in Taiwan and Korea had been conducted on a combined basis throughout the relevant periods.

In preparing the combined financial statements, the financial statement balances related to the SPS business in Taiwan were “carved-out” from the legal entity, Motorola Electronics Taiwan Ltd., and combined with the financial statements of Motorola Korea Ltd. Accordingly, the combined financial statements include certain previously unallocated general and administrative expenses related to the SPS business in Taiwan aggregating $239,445 and $574,478 for the years ended December 31, 1997 and 1998. The expenses allocated relate to costs from Motorola Electronics Taiwan Ltd.’s accounting, public affairs, and general office departments and income taxes.

The basis for the allocation of costs from the public affairs and general manager’s office was primarily based on sales and inventory levels of the SPS business in Taiwan as compared to the total sales and inventory levels of Motorola Electronics Taiwan Ltd. Costs allocated from the accounting department was based on actual hours incurred by the department on behalf of the SPS business. Income taxes were calculated as if the SPS business in Taiwan was a stand-alone legal entity.

In addition, a net foreign currency gain of $2,446,000 and a net foreign currency loss of $2,405,964 was allocated to the SPS businesses for the years ended December 31, 1997 and 1998, respectively. These gains and losses were incurred by Motorola, Inc. Motorola, Inc.’s treasury department enters into forward foreign currency contracts to hedge foreign currency positions of its subsidiaries on a global basis. Gains and losses from these contracts are allocated to individual businesses within Motorola based on the specific foreign currency contracts entered into to hedge each entity’s foreign currency denominated monetary asset and liability positions and future cash flow needs. The foreign currency balances were generally denominated in either New Taiwan dollars or Korean won.

All other costs included in net income of the SPS businesses were specifically identified as costs directly related to these businesses.

Management believes that the basis of allocation of general and administrative expenses were reasonable based on the level of services provided to the SPS business in Taiwan and that the combined financial statements include all revenues and costs directly and indirectly attributable to Motorola’s SPS businesses in Taiwan and Korea.

NOTES TO COMBINED FINANCIAL STATEMENTS — (continued)

The combined financial statements have been prepared in accordance with generally accepted accounting principles in the United States. The financial data and accompanying notes for the six-month periods ended June 30, 1998 and 1999 are unaudited but reflect all adjustments which are, in the opinion of management, necessary to present such information on a basis consistent with that applied to the audited combined financial statements as of and for the years ended December 31, 1997 and 1998.

(2) Summary of Significant Accounting Policies

Basis of combination

The combined financial statements include the SPS businesses in Taiwan and Korea which were owned by Motorola, Inc. prior to July 4, 1999. All intercompany balances and transactions between these two businesses have been eliminated.

Cash equivalents

All highly liquid investments purchased with an original effective maturity of three months or less are considered to be cash equivalents.

Inventories

Inventories are valued at the lower of cost (weighted average method) or net realizable value.

Foreign currency translation

The functional and reporting currency of the SPS businesses is the U.S. dollar. Transactions denominated in other currencies for nonmonetary assets and liabilities are translated and recorded at the exchange rates in effect when the transactions occur. Monetary assets and liabilities denominated in other currencies are translated into U.S. dollars at the end of the period. The resulting exchange gain or loss is included in results of operations.

Revenue recognition

Revenues are recognized at the time of shipment of products.

Property, plant and equipment

Property, plant and equipment is stated at cost. The SPS businesses provide for depreciation of property, plant and equipment utilizing the straight-line method over the estimated useful lives of the assets. Buildings and improvements are depreciated over 8 to 40 years, machinery and equipment over 3 to 8 years and furniture and fixtures over 4 to 10 years.

Income taxes

Income taxes are accounted for under the asset and liability method. Deferred tax assets and liabilities are recognized for the future tax consequences attributable to differences between the financial statement carrying amounts of existing assets and liabilities and their respective tax basis. Deferred tax asset and liabilities are measured using enacted tax rates expected to apply to taxable income in the periods in which those temporary differences are expected to be recovered or settled. The effect on deferred tax assets and liabilities of a change in tax rates is recognized as income in the period that includes the enactment date.

Accounting estimates

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

(3) Transactions with Related Parties

Prior to July 4, 1999, the SPS businesses were captive operations of Motorola’s semiconductor business segment. The operations of the SPS businesses included purchasing semiconductor wafers from various Motorola locations, performing the final assembly and testing functions, and selling the resulting integrated circuit product to various Motorola businesses located throughout the world. Total sales to Motorola companies for the years ended December 31, 1997 and 1998 aggregated $657 million and $753 million, respectively. Total purchases from Motorola companies aggregated $626 million and $703 million for the years ended December 31, 1997 and 1998, respectively. The net balance due to the SPS businesses from Motorola companies was $7.1 million as of December 31, 1997. The net balance due from Motorola companies was $7.9 million as of December 31, 1998.

Purchase and sales prices are determined on a cost-plus basis. The cost-plus arrangement differs by each country depending on a number of factors such as market prices, local transfer pricing rules and tax strategies. Since the service performed by the SPS businesses is selling a captive operation, management is unable to estimate the historical effect on net income as if these purchases and sales were made with unrelated entities.

Pursuant to the July 3, 1999 manufacturing services agreement between the ASE Group and Motorola, the SPS businesses will continue to provide processing services to Motorola for the next three to five years. Under the agreement, Motorola will maintain ownership of the inventory and the SPS businesses will charge Motorola a fee for assembly and test services. The fees for this service will be negotiated periodically based on factors such as supply needs and market conditions. Due to the uncertainty of the future service fee rates, management is unable to estimate the impact that the new pricing structure would have had on the historical net income of the SPS businesses.

Motorola Korea Ltd. loaned funds to a related company in Korea. The loan was denominated in Korean won and carried a variable interest rate of 12% in 1997. The interest rate on the loan ranged from 13% to 20% in 1998. The outstanding loan balance as of December 31, 1997 and 1998 was $35,016 and $26,919, respectively. The related interest income was $6,428 and $5,573 in 1997 and 1998, respectively.

In 1997, the SPS business in Korea moved its operations to a new facility. As a result, plant and equipment with an aggregate net book value of approximately $107 million was sold to various Motorola companies. These assets were sold at their net book value.

Accrued payroll |  | $ | 9,177 |  |  | $ | 6,453 |
Accrued taxes |  |  | 2,147 |  |  |  | 6,347 |

(7) Short-term Debt

The SPS businesses incurred interest costs of $688,000 for the year ended December 31, 1998, related to bank overdraft balances. The interest rate on these borrowings ranged from 14.1% to 17.9% during 1998. The overdraft balance was fully paid at December 31, 1998.

(8) Retirement Plans

Employees of the SPS businesses in Taiwan are included in the Motorola Electronics Taiwan Ltd. defined benefit pension plan. The plan covers substantially all of the employees in the SPS businesses. Future retirement payments are based on the employees’ salary level upon

NOTES TO COMBINED FINANCIAL STATEMENTS — (continued)

retirement and length of service with the company. At the end of each year, an actuarial calculation is prepared in accordance with Statement of Financial Accounting Standards No. 87, “Employers’ Accounting for Pensions”. Based on this calculation, Motorola Electronics Taiwan Ltd. will transfer funds to the Central Trust of China, a government institution, equal to the projected benefit obligation. The plan was fully funded at December 31, 1997 and 1998. For financial reporting purposes in the accompanying combined financial statements, the SPS business in Taiwan has accounted for its participation in the plan as a multiemployer pension plan. Accordingly, contributions to the plan by the SPS business in Taiwan of $1.4 million and $1.2 million in 1997 and 1998, respectively, have been recognized as pension expense in the accompanying combined statements of operations. Employees who have been with the SPS business in Korea for more than one year are entitled to lump-sum payments based on current rates of pay and length of service when they leave the Company. Management’s estimated liability under the plan, equal to the amount which would be payable if all employees left the Company at the balance sheet date, has been accrued in the accompanying combined financial statements.

Under the National Pension Scheme of Korea, the SPS businesses in Korea is required to transfer a certain percentage of retirement benefits of employees to the National Pension Fund. The amount transferred will reduce the retirement and severance benefit amount payable to the employees when they leave the Company and is reflected as a direct deduction from the retirement and severance benefits liability in the accompanying combined financial statements.

At December 31, 1997 and 1998, an accrued balance of $23.4 million and $17.5 million, respectively, was included as a noncurrent liability on the combined balance sheets related to the plan of the SPS business in Korea. Pension expense of approximately 2.1 million and $1.9 million related to this plan was recorded in the statement of operations for the years ended December 31, 1997 and 1998, respectively. In addition, approximately $9.6 million was paid to employees that were terminated as a result of the SPS business in Korea’s move to a new facility in 1997 (refer to note 3). This amount was included in “selling, general and administrative expense” in the accompanying combined statement of operations for the year ended December 31, 1997.

(9) Owner’s Equity

Owner’s equity consists of the stockholder’s equity of Motorola Korea Ltd. and the SPS business in Taiwan’s interdivision balance with Motorola Electronics Taiwan Ltd. The changes in the owner’s equity balance during 1997 and 1998 are shown below:

ASE INC. AND SUBSIDIARIES

UNAUDITED PRO FORMA FINANCIAL STATEMENTS

The following unaudited pro forma statement of income for the year ended December 31, 1999 give effect to the acquisitions by Advanced Semiconductor Engineering, Inc. (“ASE”) on July 4, 1999 through its substantially-owned subsidiaries — 30% interest through ASE Test Limited and 70% interest through J&R Holding Limited and ASE Holding Limited of the Motorola Semiconductor Products Sector Businesses (the “Motorola SPS Businesses”) in a transaction accounted for as purchase. The unaudited pro forma statement of income is based on an individual financial statement of ASE for the year ended December 31, 1999. Adjustments to the statement of income for the year ended December 31, 1999 have been made to give effect to the acquisition of the Motorola SPS Businesses as if the acquisition had occurred on January 1, 1999.

Prior to being acquired by the ASE in July 1999, the Motorola SPS Businesses in Taiwan and Korea took legal ownership of the silicon wafers sourced from various Motorola facilities at Motorola-determined internal transfer prices. Therefore, the cost of the silicon wafers was included in sale and cost of sales. Commencing July 4, 1999, ASE (Chung Li) Inc. (“ASE Chung Li”) and ASE (Korea) Inc. (“ASE Korea”) no longer took legal ownership of the silicon chips and therefore excluded such purchase price from their sales and cost of sales, in conformity with the ASE’s customary accounting treatment for silicon wafers received from ASE’s customers as consignment to ASE for packaging and testing. If ASE’s accounting treatment had been in effect at ASE Chung Li and ASE Korea prior to ASE acquisition of these operations, reported net revenues and cost of revenues for the periods prior to July 4, 1999, would have been substantially lower than those set forth in the following pro forma statement of income.

The following unaudited pro forma statement of income is not necessarily indicative of the future results of operations of ASE or the results of operations which would have resulted had ASE and the Motorola SPS Businesses been combined during the period presented. In addition, the pro forma results are not intended to be a projection of future results. The unaudited pro forma statement of income should be read in conjunction with the Consolidated Financial Statements of ASE and its subsidiaries and the financial statements of the Motorola SPS Businesses, including the notes thereto, appearing elsewhere in this Registration Statement.

ASE INC. AND SUBSIDIARIES

NOTES TO UNAUDITED PRO FORMA FINANCIAL STATEMENTS

1. Basis of Presentation

The unaudited pro forma statements of income have been prepared to reflect the acquisition of the Motorola SPS Businesses by ASE, as if the acquisition had occurred on January 1, 1999.

The combined financial statements of the Motorola SPS Businesses (“the combined financial statements”) reflect the combined financial condition, results of operations and cash flows of the Motorola SPS Businesses acquired by the ASE Group.

In preparing the combined financial statements, the financial statement balances related to the Motorola SPS Businesses in Taiwan were “carved-out” from the legal entity, Motorola Electronics Taiwan Ltd., and combined with the financial statements of Motorola Korea Ltd. Accordingly, the combined financial statements include certain previously unallocated general and administrative expenses related to the Motorola SPS Businesses in Taiwan aggregating US$258,916 for the six months ended June 30, 1999. The expenses allocated relate to costs from Motorola Electronics Taiwan Ltd.’s accounting, public affairs, general office departments and income taxes.

The basis for the allocation of costs from the public affairs and general manager’s office was primarily based on sales and inventory levels of the Motorola SPS Businesses in Taiwan as compared to the total sales and inventory levels of Motorola Electronics Taiwan Ltd. Cost allocated from the accounting department was based on actual hours incurred by the department on behalf of the Motorola SPS Businesses. Income taxes were calculated as if the Motorola SPS Businesses in Taiwan was a stand-alone legal entity.

In addition, the treasury department of Motorola, Inc. (“Motorola”) enters into forward foreign currency contracts to hedge foreign currency positions of its subsidiaries of a global basis. Gains and losses from these contracts are allocated to individual businesses within a global basis. Gains and losses from these contracts and allocated to individual businesses within Motorola based on their foreign denominated monetary asset and liability positions and future cash flow needs. The foreign currency balances were generally denominated in either New Taiwan dollars or Korean won.

All other costs included in net income of the Motorola SPS Businesses were specifically identified as costs directly related to these businesses.

Management of the Motorola SPS Businesses believes that the basis of allocation of general and administrative expenses were reasonable based on the level of services provided for the Motorola SPS Businesses in Taiwan and that the combined financial statements include all revenues and costs directly and indirectly attributable to the Motorola’s SPS Businesses in Taiwan and Korea.

2. Pro Forma Adjustments

| The following adjustments were applied to the historical financial statements to arrive at the pro forma financials:
| a. Reflects the pre-acquisition operating results of the Motorola SPS Businesses. These figures reflect the 6-month results of the Motorola SPS Businesses through June 30, 1999 plus the cash bonuses paid to employees in early July of NT$202,622 thousand (US$6.5 million), net of 30.8% tax.
| b. Reflects the decrease in depreciation arising from the purchase accounting adjustments to the Motorola SPS Businesses (see note 5 detailed calculations below).

F-77

ASE INC. AND SUBSIDIARIES

NOTES TO UNAUDITED PRO FORMA FINANCIAL STATEMENTS — (Continued)

| c. Reflects the amortization of the goodwill created upon the acquisitions of the Motorola SPS Businesses over 10 years (see note 5 detailed calculations below).
| d. Reflects interest expense on payable for long-term investment at rate of 8% for one half year (the pre-acquisition period), and convertible bonds issued by ASE Test Limited (“ASE Test”). We do not expect to derive any tax benefit from interest on the convertible bonds. Tax benefit deriving from part of the interest on long-term payable is reflected in g.
| e. Part of the acquisition cost is from ASE’s present cash balances. This adjustment reflects the pro-forma reduction in interest income, at 3%, on the cash balances that were used to make the acquisition.
| f. Reflects the 10.5% minority interest of the Motorola SPS Businesses’ pre-acquisition net income (after considering the adjustments in b (net of tax) and c) and 35% of ASE Test share of the interest expense adjustment (net of tax) in d.
| g. Reflect tax effects for tax deductible interest expense and income generated, and decrease in depreciation.

3. Change for Sales Pricing in Motorola SPS Businesses

Prior to July 4, 1999, the Motorola SPS Businesses were captive operations of Motorola’s semiconductor business segment. The Motorola SPS Businesses would purchase semiconductor wafers from various Motorola locations, perform the final assembly and testing functions, and then sell the resulting integrated circuit product to various Motorola businesses located throughout the world.

Purchases and sales prices are based on a cost-plus basis. The cost-plus arrangement differs by each country depending on a number of factors such as market prices, local transfer pricing rules and tax strategies. Since the service was performed by the Motorola SPS Businesses in basically a captive operation without a substantial market, management is unable to estimate the historical effect on net income if these purchases and sales were made on an arms-length basis.

Pursuant to the July 3, 1999 manufacturing services agreement between the ASE Group and Motorola, the Motorola SPS Businesses will continue to provide processing services to Motorola for the next three to five years. Under the agreement, Motorola will maintain ownership of the inventory and ASE will charge Motorola a fee for assembly and test services. The fees for this service will be negotiated periodically based on factors such as supply needs and market conditions. Due to the uncertainty of the future service fee rates, management is unable to estimate the impact that the new pricing structure would have had on the historical net income of the Motorola SPS Businesses.

4. Purchase Cost and Goodwill

The purchase cost and calculation of goodwill for the acquisition described as above are as follows (in millions):

|  | Purchase |  | Net |  |
Acquirees |  | Cost |  | Book Value |  | Excess
Motorola SPS Businesses |  | $ | 350.1 |  |  | $ | 268.2 |  |  | $ | 81.9 |

Annex A

THE SECURITIES MARKETS OF THE ROC

The information provided in this section has been extracted from various government and other publicly available publications. References to the ROC Securities and Futures Commission in this section include both the ROC Securities and Futures Commission and the ROC Securities and Exchange Commission, its predecessor.

In September 1960, the ROC Government established the ROC Securities and Exchange Commission to supervise and control all aspects of the existing domestic securities market and the Taiwan Stock Exchange began to take shape soon thereafter. In the 1970s and the early 1980s, the ROC government implemented a number of steps designed to upgrade the quality and importance of the ROC securities markets, such as encouraging listing on the Taiwan Stock Exchange and establishing an over-the-counter market. In the mid-1980s, the ROC government began to revise its laws and regulations in a manner designed to facilitate the gradual internationalization of the ROC securities markets. In 1997, the ROC Securities and Exchange Commission was renamed the ROC Securities and Futures Commission.

The Taiwan Stock Exchange

In 1961, the ROC Securities and Futures Commission, working together with private interests, established the Taiwan Stock Exchange to provide a marketplace for securities trading. The Taiwan Stock Exchange is an auction market where the securities traded are priced according to supply and demand through announced bid and ask prices. The Taiwan Stock Exchange is a corporation owned by government-controlled and private banks and enterprises. The Taiwan Stock Exchange is independent of entities transacting business through it, each of which pays a user’s fee. Subject to limited exceptions, all transactions in listed securities by brokers, traders and integrated securities firms, that is, firms which are permitted to combine the activities of brokerage, dealing and underwriting, must be made through the Taiwan Stock Exchange.

The Taiwan Stock Exchange commenced operations in 1962 and during the remainder of the 1960s grew at a slow pace, largely due to lack of experience among issuers and investors and an unwillingness on the part of ROC businesses to offer their shares to the public. During the early 1980s, the ROC Securities and Futures Commission more actively encouraged new listings on the Taiwan Stock Exchange and the number of listed companies grew from 119 in 1983 to 472 as of July 31, 2000. As of July 31, 2000, the total market value of shares listed on the Taiwan Stock Exchange was approximately NT$11,150 billion.

The instruments traded on the Taiwan Stock Exchange have primarily been limited to common shares and bonds. However, recent legislative revisions and the current attitude of the ROC Securities and Futures Commission regarding liberalization of securities regulations have encouraged some innovation. In 1988, the Ministry of Finance permitted the issue of the ROC’s first exchangeable bonds. These bonds were exchangeable at the option of the bondholders into shares of companies owned by the issuers. Since 1989, there have been offerings of domestic convertible bonds and convertible preferred shares. In addition, beneficiary units evidencing beneficiary interests in closed-end investment funds and bonds issued by supernational financial institutions are also listed on the Taiwan Stock Exchange and traded on the ROC Over-the-Counter Securities Exchange.

In the absence of special regulatory approval, only ROC companies are permitted to list their securities on the Taiwan Stock Exchange. The ROC Securities and Futures Commission has promulgated regulations that would permit foreign issuers to list their equity securities on the Taiwan Stock Exchange. To date, only one foreign issuer has been approved to list its securities

A-1

##### Table of Contents

on the Taiwan Stock Exchange in the form of depositary receipts and supernational institutions such as the Asian Development Bank have been approved to list their debt instruments on the Taiwan Stock Exchange. The Taiwan Stock Exchange has established specific requirements for listing based on the company’s number and distribution of shareholders, years in existence, amount of capital, profitability and capital structure.

For a company to be listed, it must have been established for at least five fiscal years, have paid-in capital of at least NT$300.0 million for the latest two fiscal years and have at least 1,000 registered shareholders, including not fewer than 500 shareholders holding between 1,000 and 50,000 shares each. These 500 shareholders must together hold either at least 20% of the outstanding shares or at least 10 million shares. The company may not have an accumulated deficit for the previous fiscal year and the pre-tax net profit and operating profit levels of the company must meet any of the following requirements: (1) having exceeded 6% of paid-in capital for each of the previous two fiscal years or (2) having exceeded 6% in average of the paid-in capital for the previous two fiscal years with the profitability of the most recent fiscal year being superior than that of the preceding fiscal year or (3) having been no less than 3% of the paid-in capital for each of the previous five fiscal years. However, special listing criteria apply to high-tech companies and key businesses engaging in national economic development.

The Over-the-Counter Market

To complement the Taiwan Stock Exchange, an over-the-counter market was established in September 1982 on the initiative of the ROC Securities and Futures Commission. In early 1988, the ROC Securities and Futures Commission promulgated regulations designed to encourage trading of unlisted securities of companies whose securities do not qualify for listing on the Taiwan Stock Exchange. The over-the-counter market is currently limited to unlisted equity securities, bank and corporate bonds and debentures and government bonds. As of August 25, 2000, 312 public companies had offered their equity securities on the over-the-counter market. The value of all bonds outstanding in the over-the-counter market grew from approximately NT$76.0 billion at the end of 1983 to NT$1,161.3 billion on December 31, 1999.

Taiwan Stock Exchange Index

The Taiwan Stock Exchange Index is comparable to the Standard and Poor’s Index in the United States and the Nikkei Stock Average in Japan, insofar as it is calculated on the basis of a wide selection of listed shares weighted according to the number of shares outstanding. It is compiled using the “Paasche Formula” by dividing the market value by the base day’s total market value for the index shares. The Taiwan Stock Exchange Index is the oldest and most widely quoted market index in the ROC.

The weighing of stocks in the index is fixed as long as the number of shares outstanding remains constant. When the total number of shares outstanding changes, the weight of each stock is adjusted. Stock splits and stock dividends are adjusted automatically. Cash dividends are not included in the calculation.

As indicated above, the performance of securities traded on the Taiwan Stock Exchange has in recent years been characterized by extreme price volatility. On September 8, 2000, the TSE Index closed at 7,367.99.

Price Limits, Commissions, Transaction Tax and Other Matters

Fluctuations in the price of securities traded on the Taiwan Stock Exchange are currently subject to a restriction of 7% above and below the previous day’s closing price (or reference price set by the Taiwan Stock Exchange if the previous day’s closing price is not available because of lack of trading activity) in the case of equity securities and 5% in the case of debt securities. The price limit for movements below the previous day’s closing price was temporarily revised to 3.5% following the September 21, 1999 earthquake, but has since reverted to 7%. The ROC Securities and Futures Commission has announced that limitations on price fluctuations will be relaxed with a view towards eventually eliminating all share price fluctuation controls.

Brokerage commissions are set by the Taiwan Stock Exchange. Effective from July 1, 2000, the ceiling for commission rate for brokers is 0.1425% of the transaction price. Brokers may determine the commission rate within this ceiling, provided that they report the rates to the ROC Securities and Futures Commission. A securities transaction tax, currently levied at the rate of 0.3% of the transaction price, is payable by the seller of equity securities and a tax at the rate of 0.1% of the transaction price is payable by the seller of debt securities other than government bonds. The securities transaction taxes are withheld at the time of the transaction giving rise to the taxes. Sales of shares of companies listed on the Taiwan Stock Exchange are currently sold in “round lots” of 1,000 shares. Investors who would like to sell less than 1,000 shares of a listed company occasionally experience delays in effecting these sales. Transactions that include 500 trading lots, that is 500,000 shares, or more must be registered and executed pursuant to Taiwan Stock Exchange guidelines.

Regulation and Supervision

The ROC Securities and Futures Commission has been under the jurisdiction of the Ministry of Finance since 1981. The ROC Securities and Futures Commission has extensive regulatory authority over companies listed on the Taiwan Stock Exchange and unlisted public issuing companies generally, including ROC companies whose capital exceed the currently specified minimum amount of NT$200 million. These companies are generally required to obtain approval

A-3

##### Table of Contents

from, or register with, the ROC Securities and Futures Commission for all securities offerings. The ROC Securities and Futures Commission has promulgated regulations requiring, unless otherwise exempted, periodic reporting of financial and operating information by all public companies. In addition, the ROC Securities and Futures Commission is responsible for the establishment of standards for financial reporting and carries out licensing and supervision with respect to the other participants in the ROC securities market.

The ROC Securities and Futures Commission has responsibility for implementation of the Securities and Exchange Law and for overall administration of governmental policies in the ROC securities market. It has extensive regulatory authority over the offering, issue and trading of securities. In addition, the Securities and Exchange Law specifically empowers the ROC Securities and Futures Commission to promulgate rules under specified circumstances.

The Securities and Exchange Law prohibits market manipulation. It also permits an issuer to recover certain short-term trading profits made through purchases and sales within six months by directors, managerial personnel, supervisors and 10% or above shareholders of the issuer. The Securities and Exchange Law prohibits trading by “insiders” based on non-public information that materially affects share price movements. According to the Securities and Exchange Law, the term “insiders” includes directors, supervisors, managers and 10% or above shareholders of the issuing company and their spouses, minor children and nominees, any person who has learned the information due to an occupational or controlling relationship with the issuing company and any person who has learned the information from any of the foregoing. Sanctions include prison terms. In addition, damages may be awarded to persons injured by the transaction. Notwithstanding these regulatory requirements, there have been recurring press reports on insider trading and manipulation of stock prices in the ROC.

The Securities and Exchange Law also imposes criminal liability on certified public accountants and lawyers who make false certifications in their examination and audit of an issuer’s contracts, reports and other evidentiary documents that are related to securities transactions. ROC Securities and Futures Commission regulations require that financial reports of listed companies be audited by accounting firms consisting of at least three certified public accountants and be signed by at least two certified public accountants.

The Securities and Exchange Law was amended in January 1988 to provide for, among other matters:

| • | new regulations relating to public offerings of securities;
| • | measures to strengthen the capital structure of issuers;
| • | civil liability for material misstatements or omissions made by issuers;
| • | more stringent regulation of the securities activities of officers, directors and major shareholders of issuers;
| • | regulations regarding tender offers; and
| • | a significant expansion of the prohibitions against insider trading, including the imposition of treble civil damages and criminal sanctions.

The Securities and Exchange Law was further amended on June 30, 2000 to provide for, among other matters, the treasury stock system and criminal liabilities on certain personnel of a company for direct or indirect trading of the company’s securities against the company’s interest.

The ROC Securities and Futures Commission does not have criminal or civil enforcement powers under the Securities and Exchange Law. Criminal actions may be pursued only by the district prosecutors located in the district where the defendant is domiciled or where the violation occurred. Under ROC law, civil actions may only be brought by plaintiffs who assert that they have suffered damages. The ROC Securities and Futures Commission is directly empowered to

##### Table of Contents

curb abuses and violations of applicable laws and regulations only through administrative measures such as the issuance of warnings, temporary suspension of operation, imposition of administrative fines and revocation of licenses.

In addition to providing a market for securities trading, the Taiwan Stock Exchange has primary responsibility for reviewing applications by ROC issuers to list securities on the Taiwan Stock Exchange. In addition, the ROC Securities and Futures Commission reviews all securities offerings by listed companies. If issuers of listed securities violate relevant laws and regulations or encounter significant difficulties, the Taiwan Stock Exchange may, with the approval of the ROC Securities and Futures Commission, delist securities of these issuers.

Annex B

FOREIGN INVESTMENT AND EXCHANGE CONTROLS IN THE ROC

Foreign Investment

Historically, foreign investment in the ROC securities markets has been restricted. Since 1983, the ROC government has periodically enacted legislation and adopted regulations to permit foreign investment in the ROC securities market. Currently, non-ROC persons may invest in ROC securities through the following vehicles.

Depositary Receipts

In April 1992, the ROC Securities and Futures Commission enacted regulations permitting ROC companies with securities listed on the Taiwan Stock Exchange, with the prior approval of the ROC Securities and Futures Commission, to sponsor the issuance and sale to foreign investors of depositary receipts. Depositary receipts represent deposited shares of ROC companies. In December 1994, the Ministry of Finance allowed companies whose shares are traded on the ROC Over-the-Counter Securities Exchange or listed on the Taiwan Stock Exchange, upon approval of the ROC Securities and Futures Commission, to sponsor the issuance and sale of depositary receipts. The approval will be granted (1) if the underlying shares are newly issued shares, for a fixed number of depositary receipts or (2) if the underlying shares are not newly issued shares, for a maximum number of depositary receipts and, with limited exceptions (as described below), may not be increased without additional approvals by ROC Securities and Futures Commission.

Starting three months after the initial issue of depositary receipts, a holder of depositary receipts may request the foreign depositary bank issuing the depositary receipts to cause the underlying securities to be sold in the ROC and to distribute the proceeds of the sale to the depositary receipt holder or to withdraw from the depositary receipt facility shares represented by depositary receipts and transfer the shares to the depositary receipt holder (other than citizens of the People’s Republic of China and entities organized under the laws of the People’s Republic of China); provided that settlement for trading of shares represented by the depositary receipts through the book-entry system maintained by the Taiwan Securities Central Depositary Co. Ltd. is permitted. As discussed above, because the ROC Securities and Futures Commission approval is for a fixed or maximum number of depositary receipts, we or the foreign depositary bank may not increase the number of depositary receipts by depositing shares in a depositary receipt facility or issuing additional depositary receipts against these deposits without specific ROC Securities and Futures Commission approval, except in limited circumstances. These circumstances include issuances of additional depositary receipts in connection with:

| (1) dividends on or free distributions of shares;
| (2) the exercise by holders of existing depositary receipts of their pre-emptive rights in connection with capital increases for cash; or
| (3) if permitted under the deposit agreement and custody agreement, the purchase directly by any person or through a depositary of the underlying shares on the Taiwan Stock Exchange or the ROC Over-the-Counter Securities Exchange (as applicable) or delivery of the underlying shares for deposit in the depositary receipt facility.

However, the total number of deposited shares outstanding after an issuance under the circumstances described in clause (3) above may not exceed the number of deposited shares previously approved by the ROC Securities and Futures Commission in connection with the initial offering plus any depositary receipts created under the circumstances described in clauses (1) and (2) above (subject to any adjustment in the number of shares represented by each

##### Table of Contents

depositary receipt). Issuances of additional depositary receipts under the circumstances described in clause (3) above will be permitted to the extent that previously issued depositary receipts have been canceled and, for so long as may be required by applicable law, the shares withdrawn from the depositary receipt facility upon cancellation of the depositary receipts have been sold.

Under current ROC law, a non-ROC holder of ADSs who withdraws the underlying shares must appoint an eligible local agent to:

| (1) open a securities trading account with a local securities brokerage firm after having obtained consent from the Taiwan Stock Exchange or the ROC Over-the-Counter Securities Exchange;
| (2) remit funds; and
| (3) exercise rights on securities and perform other matters as may be designated by the holder.

In addition, a withdrawing non-ROC holder must appoint a local bank to act as custodian for handling confirmation and settlement of trades, safekeeping of securities and cash proceeds and reporting of information. Under existing ROC laws and regulations, without this account, holders of ADSs that withdraw and hold the common shares represented by the ADSs would not be able to hold or transfer the common shares, whether on the Taiwan Stock Exchange or otherwise.

Holders of ADSs withdrawing common shares represented by ADSs who are non-ROC persons are required under current ROC laws and regulations to appoint an agent in the ROC for filing tax returns and making tax payments. The agent, a “tax guarantor”, must meet qualifications set by the ROC Ministry of Finance and, upon appointment, becomes a guarantor of the withdrawing holder’s ROC tax payment obligations. In addition, under current ROC law, repatriation of profits by a non-ROC withdrawing holder is subject to the submission of evidence of the appointment of a tax guarantor to, and approval thereof by, the tax authority or submission of tax clearance certificates so long as the capital gains from securities transactions are exempt from ROC income tax. As required by the Central Bank of China, if repatriation by a holder is based on a tax clearance certificate, the aggregate amount of the cash dividends or interest on bank deposits converted into foreign currencies to be repatriated by the holder shall not exceed the amount of:

| (1) the net payment indicated on the withholding tax voucher issued by the tax authority;
| (2) the net investment gains as indicated on the holder’s certificate of tax payment; or
| (3) the aggregate transfer price as indicated on the income tax return for transfer of tax-deferred dividend shares, whichever is applicable.

Under existing laws and regulations relating to foreign exchange control, a depositary may, without obtaining further approvals from the Central Bank of China or any other governmental authority or agency of the ROC, convert NT dollars into other currencies, including U.S. dollars, in respect of the following: proceeds of the sale of shares represented by depositary receipts, proceeds of the sale of shares received as stock dividends and deposited into the depositary receipt facility and any cash dividends or cash distributions received. In addition, a depositary, also without any of these approvals, may convert incoming payments into NT dollars for purchases of underlying shares for deposit into the depositary receipt facility against the creation of additional depositary receipts. The approval from the Central Bank of China is required for a depositary on a payment-by-payment basis for conversion into NT dollars of subscription payments relating to rights offerings. A depositary may also be required to obtain foreign exchange approval from the Central Bank of China on a payment-by-payment basis for conversion from NT dollars into other currencies relating to the sale of subscription rights for

new shares. Proceeds from the sale of any underlying shares by holders of depositary receipts withdrawn from the depositary receipt facility may be converted into other currencies without obtaining Central Bank of China approval. Proceeds from sale of the underlying shares withdrawn from the depositary receipt facility may be used for reinvestment in the Taiwan Stock Exchange or the ROC Over-the-Counter Securities Exchange, subject to limitations and restrictions applicable to Qualified Foreign Institutional Investors or General Foreign Investors (as defined below in “ — Other Foreign Investment”).

Overseas Corporate Bonds

Since 1989, the ROC Securities and Futures Commission has approved a series of overseas bonds issued by ROC companies listed on the Taiwan Stock Exchange in offerings outside the ROC. Under current ROC law, overseas corporate bonds can be:

| (1) converted by bondholders, other than citizens of the People’s Republic of China and entities organized under the laws of the People’s Republic of China, into shares of ROC companies; or
| (2) subject to ROC Securities and Futures Commission approval, may be converted into depositary receipts issued by the same ROC company or by the issuing company of the exchange shares, in the case of exchangeable bonds.

The relevant regulations also permit public issuing companies to issue corporate debt in offerings outside the ROC. Proceeds from the sale of the shares converted from overseas convertible bonds may be used for reinvestment in securities listed on the Taiwan Stock Exchange or traded on the ROC Over-the-Counter Securities Exchange, subject to limitations and restrictions applicable to Qualified Foreign Institutional Investors or General Foreign Investors (as applicable).

Qualified Foreign Institutional Investors

On December 28, 1990, the Executive Yuan approved guidelines drafted by the ROC Securities and Futures Commission which, since January 1, 1991, allow direct investment in ROC securities listed on the Taiwan Stock Exchange or other ROC securities approved by the ROC Securities and Futures Commission by eligible foreign institutional investors. Under current guidelines, eligible foreign institutional investors include:

| (1) banks which rank among the top 1,000 banks in the non-Communist world having experience in international financial, securities or trust business;
| (2) insurance companies which have existed for more than three years and hold securities assets of at least US$300,000,000;
| (3) fund management institutions which have existed for more than three years and manage assets of at least US$200,000,000;
| (4) offshore fund management institutions which are more than 50% owned by ROC securities investment trust enterprises, provided the funds to be used for investment in ROC securities do not come from the ROC, funds owned by these offshore fund management institutions or mainland China;
| (5) general securities firms which have a net worth of at least US$100 million and experience in international securities investments;
| (6) offshore subsidiary securities firms which are more than 50.0% owned by an ROC securities firm or other offshore securities firms which are wholly owned by these offshore subsidiary securities firms;

B-3

##### Table of Contents

| (7) offshore subsidiary securities firms which are 100.0% owed by an ROC securities firm or other offshore securities firms which are more than 51.0% owned by these offshore subsidiary securities firm;
| (8) foreign government-owned investment institutions;
| (9) pension funds which have been set up for two years;
| (10) mutual funds, unit trusts or investment trusts which have been established for three years and have assets of at least US$200.0 million; and
| (11) other institutional investors approved by the ROC Securities and Futures Commission.

Eligible foreign institutional investors who wish to qualify as Qualified Foreign Institutional Investors need to apply for and receive an investment permit from the ROC Securities and Futures Commission. Any application for investment exceeding US$50 million must also be approved by the Central Bank of China. The application with the ROC Securities and Futures Commission requires the submission of, among other documents, proof of eligibility, proof of appointment of a local agent and custodian, credentials of the local agent and custodian and a copy of the custodial contract. Foreign institutional investors who receive a permit (each a “Qualified Foreign Institutional Investor”) may currently invest up to US$1.2 billion (with limited exceptions, the maximum amount of US$1.2 billion may be exceeded) and are required to remit the full amount into the ROC within one year after receiving the investment permit. The percentage of individual foreign ownership and total foreign ownership in an ROC listed company (or a company whose shares are traded on the ROC Over-the-Counter Securities Exchange) may not exceed 50%.

Common shares represented by depositary receipts and common shares converted from overseas convertible bonds are disregarded for the purposes of calculation of the foregoing investment limits. However, if a foreign investor sells shares converted from overseas convertible bonds or common shares withdrawn from the depositary receipt facility and uses the proceeds therefrom to reinvest in securities listed on the Taiwan Stock Exchange or traded on the ROC Over-the-Counter Securities Exchange, the foreign investor will be subject to the 50% foreign ownership percentage limitations. Custodians for Qualified Foreign Institutional Investors are also required to submit to the Central Bank of China and the ROC Securities and Futures Commission a monthly report of trading activities and status of assets under custody and other matters. Capital remitted to the ROC under these guidelines may be remitted out of the ROC at any time after the date the capital is remitted to the ROC. Capital remitted out of the ROC may be returned to the ROC within one year of the outward remittance without the ROC Securities and Futures Commission’s approval. Capital gains and income on investments may be remitted out of the ROC at any time.

In addition to Qualified Foreign Institutional Investors, under existing ROC laws and regulations relating to foreign investment, individual and institutional foreign investors which meet qualifications set by the ROC Securities and Futures Commission (“General Foreign Investors”) may invest in the shares of Taiwan Stock Exchange-listed or the ROC Over-the-Counter Securities Exchange-Listed companies up to a limit of US$50.0 million (in the case of institutional investors) and US$5.0 million (in the case of individual investors) after obtaining permission from the Taiwan Stock Exchange or the ROC Over-the-Counter Securities Exchange. General Foreign Investors are also subject to the foreign ownership percentage limitations described in the preceding paragraph.

Foreign investors (other than Qualified Foreign Institutional Investors, General Foreign Investors, investors investing in overseas convertible bonds and depositary receipts) who wish

to make direct investments in the shares of ROC companies are required to submit a Foreign Investment Approval application to the Investment Commission of the ROC Ministry of Economic Affairs or other government authority. The Investment Commission or other government authority reviews each Foreign Investment Approval application and approves or disapproves each application after consultation with other governmental agencies (such as the Central Bank of China and the ROC Securities and Futures Commission).

Under current law, any non-ROC person possessing a Foreign Investment Approval may repatriate annual net profits, interest and cash dividends attributable to the approved investment. Stock dividends attributable to the investment, investment capital and capital gains attributable to such investment may be repatriated by the non-ROC person possessing a foreign investment approval after approvals of the Investment Commission or other government authorities have been obtained.

In addition to the general restriction against direct investment by non-ROC persons in securities of ROC companies, non-ROC persons (except in limited cases) are currently prohibited from investing in certain industries in the ROC pursuant to a Negative List, as amended by the Executive Yuan. The prohibition on foreign investment in the prohibited industries specified in the Negative List is absolute in the absence of specific exemption from the application of the Negative List. Pursuant to the Negative List, certain other industries are restricted so that non-ROC persons (except in limited cases) may invest in these industries only up to a specified level and with the specific approval of the relevant competent authority which is responsible for enforcing the relevant legislation which the Negative List is intended to implement.

Exchange Controls

The Foreign Exchange Control Statute and regulations provide that all foreign exchange transactions must be executed by banks designated to handle the business, by the Ministry of Finance or by the Central Bank of China. Current regulations favor trade-related foreign exchange transactions. Consequently, foreign currency earned from exports of merchandise and services may now be retained and used freely by exporters, and all foreign currency needed for the importation of merchandise and services may be purchased freely from the designated foreign exchange banks.

Trade aside, ROC companies and resident individuals may, without foreign exchange approval, remit outside the ROC foreign currency of up to US$50,000,000 (or its equivalent) and US$5,000,000 (or its equivalent) respectively in each calendar year. In addition, ROC companies and resident individuals may, without foreign exchange approval, remit into the ROC foreign currency of up to US$50,000,000 (or its equivalent) and US$5,000,000 (or its equivalent) respectively in each calendar year. The above limits apply to remittances involving a conversion of NT dollars to a foreign currency and vice versa. A requirement is also imposed on all enterprises to register medium-and long-term foreign debt with the Central Bank of China.

In addition, foreign persons may, subject to specified requirements, but without foreign exchange approval of the Central Bank of China, remit outside and into the ROC foreign currencies of up to US$100,000 (or its equivalent) for each remittance. The above limit applies to remittances involving a conversion of NT dollars to a foreign currency and vice versa. The above limit does not, however, apply to the conversion of NT dollars into other currencies, including U.S. dollars, from the proceeds of sale of any underlying shares withdrawn from a depositary receipt facility.

Item 22. Undertakings

The undersigned registrant hereby undertakes:

| (1) To file, during any period in which offers or sales are being made, a post-effective amendment to this registration statement:

| (i) To include any prospectus required by Section 10(a)(3) of the Securities Act of 1933;
| (ii) To reflect in the prospectus any facts or events arising after the effective date of the registration statement (or the most recent post-effective amendment thereof) which, individually or in the aggregate, represent a fundamental change in the information set forth in the registration statement. Notwithstanding the foregoing, any increase or decrease in volume of securities offered (if the total dollar value of securities offered would not exceed that which was registered) and any deviation from the low or high end of the estimated maximum offering range may be reflected in the form of prospectus filed with the Commission pursuant to Rule 424(b) if, in the aggregate, the changes in volume and price represent no more than a 20 percent change in the maximum aggregate offering price set forth in the “Calculation of Registration Fee” table in the effective registration statement;

II-3

##### Table of Contents

| (iii) To include any material information with respect to the plan of distribution not previously disclosed in the registration statement or any material change to such information in the registration statement.

| (2) For the purpose of determining any liability under the Securities Act of 1933, each post-effective amendment that contains a form of prospectus shall be deemed to be a new registration statement relating to the securities offered therein, and the offering of such securities at that time shall be deemed to be the initial bona fide offering thereof.
| (3) To remove from registration by means of a post-effective amendment any of the securities being registered which remain unsold at the termination of the offering.
| (4) To file a post-effective amendment to the registration statement to include any financial statements required by Rule 3-19 of Regulation S-K at the start of any delayed offering or throughout a continuous offering.
| (5) For purposes of determining any liability under the Securities Act of 1933, the information omitted from the form of prospectus filed as part of this registration statement in reliance upon Rule 430A and contained in a form of prospectus filed by the registrant pursuant to Rule 424(b)(1) or (4) or 497(h) under the Securities Act shall be deemed to be part of this registration statement as of the time it was declared effective.
| (6) To respond to requests for information that is incorporated by reference into the prospectus pursuant to Items 4, 10(b), 11 or 13 of Form F-4, within one business day of receipt of such request, and to send the incorporated documents by first class mail or other equally prompt means, and (ii) to arrange or provide for a facility in the U.S. for the purpose of responding to such requests. The undertaking in subparagraph (i) above includes information contained in documents filed subsequent to the effective date of this registration statement through the date of responding to the request.
| (7) To supply by means of a post-effective amendment all information concerning a transaction and the company being acquired therein, that was not the subject of and included in this registration statement when it became effective.
| (8) To provide to the underwriter at the closing specified in the underwriting agreements, certificates in such denominations and registered in such names as required by the underwriter to permit prompt delivery to each purchaser.
| (9) That insofar as indemnification for liabilities arising under the Securities Act may be permitted to directors, officers and controlling persons of the registrant pursuant to the foregoing provisions, or otherwise, the registrant has been advised that in the opinion of the Securities and Exchange Commission such indemnification is against public policy as expressed in the Act and is, therefore, unenforceable. In the event that a claim for indemnification against such liabilities (other than the payment by the registrant of expense incurred or paid by a director, officer or controlling person of the registrant in the successful defense of any action, suit or proceeding) is asserted by such director, officer or controlling person in connection with the securities being registered, the registrant will, unless in the opinion of its counsel the matter has been settled by controlling precedent, submit to a court of appropriate jurisdiction the question whether such indemnification by it is against public policy as expressed in the Act and will be governed by the final adjudication of such issue.
