OFFER TO EXCHANGE

$250,000,000
7 1/8% Senior Notes due 2011
that have been registered under the Securities Act of 1933, as amended
for any and all of its outstanding
7 1/8% Senior Notes due 2011
that were issued and sold in a transaction exempt from registration
under the Securities Act of 1933, as amended

      Amkor Technology, Inc., a Delaware corporation, hereby offers to exchange, upon the terms and conditions set forth in this prospectus and the accompanying letter of transmittal, up to $250 million in aggregate principal amount of its registered 7 1/8% senior notes due 2011, which we refer to as the “exchange notes,” for the same principal amount of its outstanding unregistered 7 1/8% senior notes due 2011, which we refer to as the “original notes.”

      The terms of the exchange notes are substantially identical to the terms of the original notes, except that the exchange notes will generally be freely transferable and do not contain certain terms with respect to liquidated damages. We will issue the exchange notes under the indenture governing the original notes (the “Indenture”). For a description of the principal terms of the exchange notes, see “Description of the Notes.”

     The exchange offer will expire at 5:00 p.m., New York City time, on July 6, 2004, unless we extend the offer. At any time prior to the expiration date, you may withdraw your tender of any original notes; otherwise, such tender is irrevocable. We will receive no cash proceeds from the exchange offer.

      The exchange notes constitute a new issue of securities for which there is no established trading market. Any original notes not tendered and accepted in the exchange offer will remain outstanding. To the extent original notes are tendered and accepted in the exchange offer, your ability to sell untendered, and tendered but unaccepted, original notes could be adversely affected. Following consummation of the exchange offer, the original notes will continue to be subject to their existing transfer restrictions and we will have no further obligations to provide for the registration of the original notes under the Securities Act of 1933, as amended (the “Securities Act”). We cannot guarantee that an active trading market will develop or give assurances as to the liquidity of the trading market for either the original notes or the exchange notes.

      This prospectus, as it may be amended or supplemented from time to time, may be used by a broker-dealer in connection with resales of exchange notes received for original notes that were acquired by such broker-dealer for its own account as a result of market-making activities or other trading activities. If any holder of the original notes notifies us prior to the 20th business day following the consummation of the exchange offer that it is prohibited by law or policy of the Securities and Exchange Commission (the “SEC”) from participating in the exchange offer, that it may not resell the exchange notes acquired by it in the exchange offer to the public without delivering a prospectus, and this prospectus is not appropriate or available for such resales by it, or that it is a broker-dealer and holds original notes acquired directly from us or our affiliates, we will use commercially reasonable efforts to file with the SEC a shelf registration statement to register for public resale the original notes held by any such holder who provides us with certain information for inclusion in the shelf registration statement, such shelf registration statement to be effective by the SEC on or prior to 120 days after such obligation to file a shelf registration statement arises.

     Investing in the exchange notes involves certain risks. Please read “Risk Factors” beginning on page 8 of this prospectus.

      This prospectus and the letter of transmittal are first being mailed to all holders of the original notes on June 3, 2004.

     Neither the SEC nor any state securities commission has approved or disapproved of the exchange notes or determined if this prospectus is truthful or complete. Any representation to the contrary is a criminal offense.

The date of this prospectus is June 3, 2004.

PROSPECTUS SUMMARY

      This summary may not contain all the information that may be important to you. You should read the entire prospectus, including the additional documents to which we refer you, before making an investment decision. See “Where You Can Find More Information.” In this prospectus, unless otherwise noted, “we,” “our,” “us,” and “Amkor” refer to Amkor Technology, Inc. and its consolidated subsidiaries.

AMKOR TECHNOLOGY, INC.

      Amkor is one of the world’s largest subcontractors of semiconductor packaging and test services. The company has built a leading position by:
 	 	 	
 	• 	Providing a broad portfolio of packaging and test technologies and services;	
 	 	 	
 	• 	Maintaining a leading role in the design and development of new package and test technologies;	
 	 	 	
 	• 	Cultivating long-standing relationships with customers, including many of the world’s leading semiconductor companies;	
 	 	 	
 	• 	Developing expertise in high-volume manufacturing; and	
 	 	 	
 	• 	Diversifying our operational scope by establishing production capabilities in China, Japan and Taiwan, in addition to long-standing capabilities in Korea and the Philippines.	
      The semiconductors that we package and test for our customers ultimately become components in electronic systems used in communications, computing, consumer, industrial, automotive and military applications. Our customers include, among others, Agilent Technologies, Atmel Corporation, Conexant Systems, Inc., Infineon Technologies AG, Intel Corporation, Philips Electronics N.V., Samsung Electronics Corporation LTD, ST Microelectronics PTE, Texas Instruments Inc. and Toshiba Corporation. The outsourced semiconductor packaging and test market is very competitive. We also compete with the internal semiconductor packaging and test capabilities of many of our customers, some of whom can use us as a source of overflow capacity.

      Packaging and test are an integral part of the semiconductor manufacturing process. Semiconductor manufacturing begins with silicon wafers and involves the fabrication of electronic circuitry into complex patterns, thus creating individual chips on the wafers. The packaging process creates an electrical interconnect between the semiconductor chip and the system board. In packaging, the fabricated semiconductor wafers are cut into individual chips which are then attached to a substrate and encased in a protective material to provide optimal electrical and thermal performance. Increasingly, packages are custom designed for specific chips and specific end-market applications. The packaged chips are then tested using sophisticated equipment to ensure that each packaged chip meets its design specifications.

      We historically marketed the output of fabricated semiconductor wafers provided by a wafer fabrication foundry owned and operated by Anam Semiconductor, Inc. (“ASI”). On February 28, 2003, we sold our wafer fabrication services business to ASI. We reflect our wafer fabrication services segment as a discontinued operation and have restated our historical results.

      We were incorporated in 1997 in the state of Delaware. Our principal offices are located at 1345 Enterprise Drive, West Chester, Pennsylvania 19380. Our telephone number is (610) 431-9600 and our website can be accessed at www.amkor.com. Information contained in our website does not constitute part of this prospectus.

SUMMARY OF THE EXCHANGE OFFER

      On March 12, 2004, we completed a private offering of our 7 1/8% Senior Notes due March 15, 2011. We refer to these notes as the original notes. We received aggregate net proceeds, before expenses and commissions, of $250 million from the sale of the original notes.

      In connection with the sale of the original notes, we entered into a Registration Rights Agreement with the initial purchasers of the original notes. Under the Registration Rights Agreement, we have agreed to file a registration statement regarding the exchange of the original notes for up to $250 million aggregate principal amount of 7 1/8% Senior Notes due March 15, 2011 which are registered under the Securities Act. We refer to the notes issued for the original notes in this exchange offer as the exchange notes. We have also agreed to use our commercially reasonable efforts to cause the registration statement to become effective with the SEC by October 8, 2004. You should read the discussion under the heading “Description of the Notes” beginning on page 31 for more information about the exchange notes. After the exchange offer is completed, you will no longer be entitled to any exchange or, with limited exceptions, registration rights for your original notes.

The Exchange Offer	 	We are offering to exchange up to $250 million aggregate principal amount of the exchange notes, which have been registered under the Securities Act, for up to $250 million aggregate principal amount of the original notes. Original notes may only be exchanged in $1,000 increments. We will exchange the applicable exchange notes for all original notes that are validly tendered and not withdrawn prior to the expiration of the exchange offer.	
 	 	 	
 	 	The form and terms of the exchange notes are identical in all material respects to those of the original notes, except the exchange notes will not be subject to transfer restrictions and holders of the exchange notes, with limited exceptions, will have no registration rights. Also, the exchange notes will not include provisions contained in the original notes that require us to pay liquidated damages in the event we fail to satisfy our registration obligations with respect to the original notes.	
 	 	 	
 	 	Original notes that are not tendered for exchange will continue to be subject to transfer restrictions and, with limited exceptions, will not have registration rights. Therefore, the market for secondary resales of original notes that are not tendered for exchange is likely to be minimal.	
 	 	 	
 	 	We will issue registered exchange notes on or promptly after the expiration of the exchange offer.	
 	 	 	
Expiration Date	 	The exchange offer will expire at 5:00 p.m., New York City time, on July 6, 2004, unless we decide to extend the expiration date.	
 	 	 	
Conditions to the Exchange Offer	 	The exchange offer is subject to customary conditions. This exchange offer is not conditioned upon any minimum principal amount of original notes being tendered.	
 	 	 	
Procedures for Tendering Notes	 	If you wish to tender your original notes for exchange notes, you must:	
 	 	 	
 	 	• complete and sign the enclosed letter of transmittal by following the related instructions, and	
 	 	 	
 	 	• send the letter of transmittal, as directed in the instructions, together with any other required documents, to the exchange	
2

 
 	 	 	
 	 	agent either (1) with the original notes to be tendered, or (2) in compliance with the specified procedures for guaranteed delivery of the original notes described in “The Exchange Offer — Guaranteed Delivery Procedures.”	
 	 	 	
 	 	Brokers, dealers, commercial banks, trust companies and other nominees may also effect tenders by book-entry transfer through DTC’s Automated Tender Offer Program (“ATOP”). If your original notes are registered in the name of a broker, dealer, commercial bank, trust company or other nominee, we urge you to contact that person promptly if you wish to tender your original notes pursuant to this exchange offer. See “The Exchange Offer — Procedures for Tendering.”	
 	 	 	
 	 	Please do not send your letter of transmittal or certificates representing your original notes to us. Those documents should be sent only to the exchange agent. Questions regarding how to tender and requests for information should be directed to the exchange agent. See “The Exchange Offer — Exchange Agent.”	
 	 	 	
Guaranteed Delivery Procedures	 	You must tender your original notes according to the guaranteed delivery procedures described in “The Exchange Offer — Guaranteed Delivery Procedures” if any of the following apply:	
 	 	 	
 	 	• you wish to tender your original notes but they are not immediately available,	
 	 	 	
 	 	• you cannot deliver your original notes, the letter of transmittal or any other required documents to the exchange agent prior to the expiration date, or	
 	 	 	
 	 	• you cannot comply with the applicable procedures under DTC’s ATOP prior to the expiration date.	
 	 	 	
Resale of the Exchange Notes	 	Except as provided below, we believe that the exchange notes may be offered for resale, resold and otherwise transferred by you without compliance with the registration and prospectus delivery provisions of the Securities Act provided that:	
 	 	 	
 	 	• the exchange notes are being acquired in the ordinary course of business,	
 	 	 	
 	 	• you are not participating, do not intend to participate, and have no arrangement or understanding with any person to participate in the distribution of the exchange notes issued to you in the exchange offer,	
 	 	 	
 	 	• you are not one of our affiliates,	
 	 	 	
 	 	• you are not a broker-dealer tendering original notes acquired directly from us for your account, and	
 	 	 	
 	 	• you are not prohibited by law or any policy of the SEC from participating in the exchange offer.	
 	 	 	
 	 	Our belief is based on interpretations by the staff of the SEC, as set forth in no-action letters issued to third parties that are not related to us. The SEC has not considered this exchange offer in the context of a no-action letter, and we cannot assure you that the	
3

 
 	 	 	
 	 	SEC would make similar determinations with respect to this exchange offer. If any of these conditions are not satisfied, or if our belief is not accurate, and you transfer any exchange notes issued to you in the exchange offer without delivering a resale prospectus meeting the requirements of the Securities Act or without an exemption from registration of your exchange notes from those requirements, you may incur liability under the Securities Act. We will not assume, nor will we indemnify you against, any such liability.	
 	 	 	
 	 	Each broker-dealer that receives exchange notes for its own account in exchange for original notes, where the original notes were acquired by such broker-dealer as a result of market-making or other trading activities, must acknowledge that it will deliver a prospectus in connection with any resale of such exchange notes. See “Plan of Distribution.”	
 	 	 	
Record Date	 	We mailed this prospectus and the related offer documents to the registered holders of the original notes on June 3, 2004.	
 	 	 	
Withdrawal Rights	 	You may withdraw the tender of your original notes at any time prior to the expiration date of the exchange offer. You must follow the withdrawal procedures as described in “The Exchange Offer — Withdrawal of Tenders.”	
 	 	 	
If You Fail to Exchange Your Original Notes	 	If you do not exchange your original notes for exchange notes in the exchange offer, you will continue to be subject to the restrictions on transfer provided in the original notes and Indenture governing those notes. In general, you may not offer to sell your original notes unless they are registered under the federal securities laws or are sold in a transaction exempt from or not subject to the registration requirements of the federal securities laws and applicable state securities laws.	
 	 	 	
Certain United States Federal Income Tax Considerations	 	The exchange of original notes for exchange notes will not be a taxable exchange for United States federal income tax purposes. Please read “Certain United States Federal Income Tax Considerations” on page 68.	
 	 	 	
Use of Proceeds	 	We will not receive any proceeds from the issuance of the exchange notes pursuant to the exchange offer. Except as described in “The Exchange Offer — Fees and Expenses,” we will pay the expenses incident to the exchange offer.	
 	 	 	
Registration Rights	 	If we fail to complete the exchange offer as required by the Registration Rights Agreement, we may be obligated to pay additional interest to holders of the original notes. Please read “Description of the Notes — Registration Rights; Liquidated Damages” beginning on page 48 for more information regarding your rights as a holder of the original notes.

THE EXCHANGE NOTES

      The form and terms of the exchange notes to be issued in the exchange offer are the same as the form and terms of the original notes, except that the exchange notes will be registered under the Securities Act and, therefore, will not bear legends restricting their transfer, will not contain terms providing for liquidated damages if we fail to perform our registration obligations with respect to the original notes and, with limited exceptions, will not be entitled to registration rights under the Securities Act. The exchange notes will evidence the same debt as the original notes, and both the original notes and the exchange notes are governed by the same Indenture.

 	 	• the exchange notes will rank equally with all our existing and future unsecured senior debt including our 9.25% senior notes due 2008 and our 7.75% senior notes due 2013; and	
 	 	 	
 	 	• the exchange notes will rank senior to all our existing and future debt that expressly provides that it is subordinated to the exchange notes, including our 10.50% senior subordinated notes due 2009, our 5.75% convertible subordinated notes due 2006 and our 5.00% convertible subordinated notes due 2007.

See “Description of the Notes — Optional Redemption.”	
 	 	 	
Change in Control	 	If we experience a change in control, we will be required to make an offer to repurchase the exchange notes at a price equal to 101% of the principal amount plus accrued and unpaid interest, if any, to the date of repurchase. For more detailed information, see “Description of the Notes — Repurchase at the Option of Holder — Offer to Repurchase Upon Change of Control.”	
 	 	 	
Covenants	 	We will issue the exchange notes under the Indenture with Wells Fargo Bank, National Association, as Trustee. The Indenture will, among other things, restrict our ability and the ability of our subsidiaries to:

In order to achieve a ratio of earnings to fixed charges of 1:1, we would have had to generate an additional $45.3 million of earnings in the year ended December 31, 2003. The ratio of earnings to fixed charges was less than 1:1 for the year ended December 31, 2002. In order to achieve a ratio of earnings to fixed charges of 1:1, we would have had to generate an additional $564.3 million of earnings in the year ended December 31, 2002. The ratio of earnings to fixed charges was less than 1:1 for the year ended December 31, 2001. In order to achieve a ratio of earnings to fixed charges of 1:1, we would have had to generate an additional $438.5 million of earnings in the year ended December 31, 2001.

RISK FACTORS

     You should carefully consider the risks described below and other information contained in this prospectus before making an investment decision. The risks and uncertainties described below are not the only ones facing our company. Additional risks and uncertainties not presently known to us, or that we currently deem immaterial, may also impair our business operations. We cannot assure you that any of the events discussed in the risk factors below will not occur. If they do, our business, financial condition or results of operations could be materially adversely affected. In such case, the trading price of the original notes and the exchange notes could decline.

     This prospectus contains forward-looking statements made as of the date of this prospectus regarding our expected performance that involve risks and uncertainties. Our actual results could differ materially from those anticipated in these forward-looking statements as a result of certain factors, including the risks faced by us described below and elsewhere in this prospectus.

Risks Relating to the Exchange Offer

 	Because there is no public market for the exchange notes, you may not be able to sell your exchange notes.	
      The exchange notes will be registered under the Securities Act, but will constitute a new issue of securities with no established trading market, and there can be no assurance as to:
 	 	 	
 	• 	the liquidity of any trading market that may develop;	
 	 	 	
 	• 	the ability of holders to sell their exchange notes; or	
 	 	 	
 	• 	the price at which the holders would be able to sell their exchange notes.	
      The exchange notes will not be listed on any exchange or market. If a trading market were to develop, the exchange notes might trade at higher or lower prices than their principal amount or purchase price, depending on many factors, including prevailing interest rates, the market for similar securities and our financial performance. Any market-making activity in the exchange notes will be subject to the limits imposed by the Securities Act and the Exchange Act.

The market prices quoted for the notes may be adversely affected by changes in:
 	 	 	
 	• 	the overall market for high yield securities;	
 	 	 	
 	• 	our financial performance or prospects;	
 	 	 	
 	• 	the prospects for companies in the semiconductor industry generally; or	
 	 	 	
 	• 	prevailing interest rates and general economic positions.	
      As a result, we cannot assure holders of notes that an active trading market will develop for the notes or that any trading market that does develop will be liquid.

      In addition, any original note holder who tenders in the exchange offer for the purpose of participating in a distribution of the exchange notes may be deemed to have received restricted securities and, if so, will be required to comply with the registration and prospectus delivery requirements of the Securities Act in connection with any resale transaction.

 	Your original notes will not be accepted for exchange if you fail to follow the exchange offer procedures.	
      We will issue exchange notes pursuant to the exchange offer only after a timely receipt of your original notes, a properly completed and duly executed letter of transmittal and all other required documents, or if you comply with the guaranteed delivery procedures for tendering your original notes. Therefore, if you want to tender your original notes, please allow sufficient time to ensure timely delivery. If we do not receive your original notes, letter of transmittal and all other required documents by the expiration date of the exchange offer, or if you do not otherwise comply with the guaranteed delivery procedures for tendering your original notes, we will not accept your original notes for exchange. We are under no duty to give notification of defects or irregularities with respect to the tenders of original notes for exchange. If there are defects or irregularities with respect to your tender of original notes, we will not accept your original notes for exchange.

8

 

 	If you do not exchange your original notes, your original notes will continue to be subject to the existing transfer restrictions and you may be unable to sell them.	
      We did not register the original notes, nor do we intend to do so following the exchange offer. Original notes that are not tendered will therefore continue to be subject to the existing transfer restrictions and may be transferred only in limited circumstances under applicable securities laws. If you do not exchange your original notes, you will lose your right to have your original notes registered under the federal securities laws. As a result, if you hold original notes after the exchange offer, you may be unable to sell your original notes. We have no obligation, except in limited circumstances, nor do we currently intend, to file an additional registration statement to cover the resale of any original notes that are not tendered in the exchange offer or to re-offer to exchange the exchange notes for original notes following the expiration of the exchange offer.

Risks Related to an Investment in the Notes

 	The following risk factors apply to both the original notes and the exchange notes.	

 	High leverage and restrictive covenants — our substantial indebtedness could adversely affect our financial condition and prevent us from fulfilling our obligations under the notes.	
     Substantial Leverage. We have a significant amount of indebtedness. In addition, despite current debt levels, the terms of the indentures governing the notes and our other securities do not prohibit us or our subsidiaries from incurring substantially more debt. If new debt is added to our consolidated debt level, the related risks that we now face could intensify. The following table shows certain important financial data and credit ratio as of March 31, 2004:
 	 	 	 	 	
 	 	At March 31, 2004	
 	 	Actual

Stockholders’ equity	 	 	421,500	 	
Ratio of total debt to stockholders’ equity	 	 	4.2x	 	
      We were required to pay to Citizen Watch Co., Ltd. (“Citizen”) 1.7 billion Japanese yen in deferred purchase price and other contingent payments in connection with our purchase of the semiconductor packaging business of Citizen. In April 2003, we made a payment of 300.0 million yen, or $2.5 million on date of payment. Pending the resolution of a controversy relating to patents acquired from Citizen, we are withholding payment of 1.4 billion yen ($13.3 million based on the spot exchange rate at March 31, 2004).

      On May 17, 2004, we announced that we had entered into a strategic long-term agreement with International Business Machines Corporation (“IBM”) for semiconductor assembly and test services. The transaction is valued at approximately $145 million, consisting of $114 million for land, buildings and fixtures, and $31 million for equipment and intangibles. We will pay IBM a total of $63 million for fixtures, equipment, intangibles and intellectual property, with payments of $20 million at closing, expected May 31, 2004, and $43 million in the fourth quarter of 2004. Further, we will pay $82 million to the China building developer in the fourth quarter of 2004.

      Covenants in the agreements governing our existing debt, and debt we may incur in the future, may materially restrict our operations, including our ability to incur debt, pay dividends, make certain investments and payments, and encumber or dispose of assets. In addition, financial covenants contained in agreements relating to our existing and future debt could lead to a default in the event our results of operations do not meet our plans and we are unable to amend such financial covenants prior to default. A default under one debt instrument may also trigger cross-defaults under our other debt instruments. An event of default under any debt instrument, if not cured or waived, could have a material adverse effect on us. See “Description of the Notes — Certain Covenants” beginning on page 34.

      Our substantial indebtedness could have important consequences to holders of the notes. For example, it could:
 	 	 	
 	• 	make it more difficult for us to satisfy our obligations with respect to the notes;	
 	 	 	
 	• 	increase our vulnerability to general adverse economic and industry conditions;	
9

 
 	 	 	
 	• 	limit our ability to fund future working capital, capital expenditures, research and development and other general corporate requirements;	
 	 	 	
 	• 	require us to dedicate a substantial portion of our cash flow from operations to service payments on our debt;	
 	 	 	
 	• 	limit our flexibility to react to changes in our business and the industry in which we operate;	
 	 	 	
 	• 	place us at a competitive disadvantage to any of our competitors that have less debt; and	
 	 	 	
 	• 	limit, along with the financial and other restrictive covenants in our indebtedness, among other things, our ability to borrow additional funds.	
     Ability to Service Debt. We cannot assure you that our business will generate cash in an amount sufficient to enable us to service our debt, including the notes, or to fund our other liquidity needs. We expect that substantial amounts of our debt will come due prior to the final maturity date of the notes, which we will be required to repay or refinance. Our 5.75% convertible subordinated notes due 2006, our 5.00% convertible subordinated notes due 2007, our 9.25% senior notes due 2008, our 10.5% senior subordinated notes due 2009, and amounts outstanding under our existing secured debt will mature prior to the 2011 maturity date of the notes and will be payable in cash unless the holders of the convertible notes elect to convert the principal amount of such notes into our common stock. In addition, we may need to refinance all or a portion of our debt, including the notes, on or before maturity. We cannot assure you that we will be able to refinance any of our debt on commercially reasonable terms or at all.

 	Effective subordination of the notes to liabilities of our subsidiaries — your right to receive payments on the notes from funds provided by our subsidiaries is junior in right of payment to the claims of the creditors of our subsidiaries.	
      We conduct a large portion of our operations through our subsidiaries. Accordingly, our ability to meet our cash obligations is dependent upon the ability of our subsidiaries to make cash payments to us. For the three months ended March 31, 2003 and March 31, 2004, revenues of our subsidiaries were approximately $165.7 and $209.8 million, respectively. We expect distributions from our subsidiaries to be a large source of funds for payment of the interest on the notes. The claims of creditors (including trade creditors) of any subsidiary will generally have priority as to the assets of such subsidiary over the claims of the holders of the notes. In the event of a liquidation of any of our subsidiaries, our right to receive the assets of any such subsidiary (and the resulting right of the holders of the notes to participate in the distribution of the proceeds of those assets) will effectively be subordinated by operation of law to the claims of creditors (including trade creditors) of such subsidiary and holders of such subsidiary’s preferred stock and any guarantees by such subsidiary of our indebtedness, such as the subsidiary guarantees under our senior secured credit facility. In the event of the liquidation, bankruptcy, reorganization, insolvency, receivership or similar proceeding or any assignment for the benefit of our creditors or a marshaling of our assets or liabilities, holders of the notes may receive ratably less than other such creditors or interest holders. As of March 31, 2004, the notes would have been effectively subordinated to $381.0 million of indebtedness and other liabilities of our subsidiaries, including trade payables but excluding intercompany obligations.

 	Financing change of control offer — we may not have, or be able to raise, the funds necessary to finance an offer to repurchase the notes following a change of control or we may be prohibited from doing so by our secured credit facilities.	
      Upon the occurrence of a change of control, we must offer to repurchase all outstanding notes. However, it is possible that we will not have sufficient funds at the time of the change of control to make the required repurchases of notes or that restrictions in our credit facilities or other debt agreements may not allow such repurchases.

10

 

 	Difficulties in enforcing judgments in foreign jurisdictions.	
      Since a large portion of our assets are located outside the U.S., any judgments obtained in the U.S. against us, including judgments with respect to the payment of principal, premium, interest, offer price, or other amounts payable with respect to the notes may be not collectible within the U.S. If holders of notes intend to enforce a judgment obtained in the U.S. against our assets located outside the U.S., they may be subject to additional procedures and other difficulties which would not be required for enforcement of such judgment in the U.S.

Risks Related to Our Business

 	Dependence on the highly cyclical semiconductor and electronic products industries — we operate in volatile industries, and industry downturns harm our performance.	
      Our business is tied to market conditions in the semiconductor industry, which is highly cyclical. Because our business is, and will continue to be, dependent on the requirements of semiconductor companies for subcontracted packaging and test services, any downturn in the semiconductor industry or any other industry that uses a significant number of semiconductor devices, such as the personal computer and telecommunication devices industries, could have a material adverse effect on our business. We experienced significant recovery in most of our packaging services during 2002 and 2003. Beginning in the second half of 2003, a large number of customers over-supported their forecasts as demand materialized faster than initially projected. However, there still remains some uncertainty as to the sustainability of these trends. If industry conditions do not continue to improve, we could sustain significant losses which could materially impact our business including our liquidity.

 	Fluctuations in operating results — our results have varied and may vary significantly as a result of factors that we cannot control.	
      Many factors could materially and adversely affect our revenues, gross profit and operating income, or lead to significant variability of quarterly or annual operating results. Our profitability is dependent upon the utilization of our capacity, semiconductor package mix, the average selling price of our services and our ability to control our costs including labor, material, overhead and financing costs. Our operating results have varied significantly from period to period. During the three year period ended December 31, 2003, and continuing into the quarter ending March 31, 2004, our revenues, gross margins and operating income have fluctuated significantly as a result of the following factors over which we have little or no control and which we expect to continue to impact our business:
 	 	 	
 	• 	fluctuation in demand for semiconductors and the overall health of the semiconductor industry,	
 	 	 	
 	• 	changes in our capacity utilization,	
 	 	 	
 	• 	declining average selling prices,	
 	 	 	
 	• 	changes in the mix of semiconductor packages,	
 	 	 	
 	• 	absence of backlog and the short-term nature of our customers’ commitments and the impact of these factors on the timing and volume of orders relative to our production capacity,	
 	 	 	
 	• 	changes in costs, availability and delivery times of raw materials and components,	
 	 	 	
 	• 	changes in labor costs to perform our services,	
 	 	 	
 	• 	the timing of expenditures in anticipation of future orders,	
 	 	 	
 	• 	changes in effective tax rates,	
 	 	 	
 	• 	high leverage and restrictive covenants,	
 	 	 	
 	• 	warranty and product liability claims and associated legal fees,	
 	 	 	
 	• 	international events that impact our operations and environmental events such as earthquakes, and	
11

 
 	 	 	
 	• 	difficulties integrating acquisitions and ability to attract qualified employees to support our geographic expansion.	
      We have historically been unable to accurately predict the impact of these factors upon our results for a particular period. We also expect that these factors as well as the factors set forth below, which have not significantly impacted our recent historical results, may impair our future business operations and may materially and adversely affect our revenues, gross profit and operating income, or lead to significant variability of quarterly or annual operating results:
 	 	 	
 	• 	the availability and cost of financing for expansion,	
 	 	 	
 	• 	loss of key personnel or the shortage of available skilled workers,	
 	 	 	
 	• 	rescheduling and cancellation of large orders,	
 	 	 	
 	• 	intellectual property transactions and disputes, and	
 	 	 	
 	• 	fluctuations in our manufacturing yields.	

 	Declining average selling prices — the semiconductor industry places downward pressure on the prices of our products.	
      Prices for packaging and test services have declined over time. Historically, we have been able to partially offset the effect of price declines by successfully developing and marketing new packages with higher prices, such as advanced leadframe and laminate packages, by negotiating lower prices with our material vendors, and by driving engineering and technological changes in our packaging and test processes which resulted in reduced manufacturing costs. During 2003 and 2002, as compared to the comparable prior year periods, the decline in average selling prices eroded margins by 6% and 16%, respectively, and in the three months ended March 31, 2004 they declined approximately 11% as compared to average selling prices in the comparable period in 2003. We expect that average selling prices for our packaging and test services will continue to decline in the future. If our semiconductor package mix does not shift to new technologies with higher prices or we cannot reduce the cost of our packaging and test services to offset a decline in average selling prices, our future operating results will suffer.

 	Investment in ASI — our results and financial condition may be adversely affected by decreases in the price of ASI’s common stock.	
      At March 31, 2004, we owned 14.7 million shares, or 12%, of ASI’s voting stock. We currently account for our investment in ASI as a marketable security that is available for sale. We intend to sell our remaining investment in ASI. The ultimate level of proceeds from the sale of our remaining investment in ASI could be less than the current carrying value of $55.1 million. In addition, in the event of a decline in the market value of the ASI stock that is not temporary, we will be required to record a charge to earnings for the unrealized loss, and a new cost basis for the stock will be established.

      In April 2004, we sold 10.1 million shares of ASI common stock for approximately $49.7 million, or $4.91 per share, based on the spot exchange rate as of the transaction dates, reducing our ownership to approximately 4%. The pre-tax gain related to this transaction is $21.6 million and was recorded as other expense (income) during the second quarter of 2004.

      In connection with our sale of ASI shares to Dongbu in September 2002, Amkor and Dongbu agreed to use their best efforts to provide releases and indemnifications to the past and incumbent chairman, directors and officers of ASI, including James Kim, our CEO and chairman, and members of his family, from any and all liabilities arising out of the performance of their duties at ASI between January 1, 1995 and December 31, 2001. We are not aware of any claims or other liabilities which these individuals would be released from or for which they would receive indemnification.

12

 

 	Absence of backlog — we may not be able to adjust costs quickly if our customers’ demand falls suddenly.	
      Our packaging and test business does not typically operate with any material backlog. We expect that in the future our quarterly net revenues from packaging and test will continue to be substantially dependent upon our customers’ demand in that quarter. None of our customers have committed to purchase any significant amount of packaging or test services or to provide us with binding forecasts of demand for packaging and test services for any future period. In addition, our customers could reduce, cancel or delay their purchases of packaging and test services. Because a large portion of our costs is fixed and our expense levels are based in part on our expectations of future revenues, we may be unable to adjust costs in a timely manner to compensate for any revenue shortfall.

 	Risks associated with international operations — we depend on our factories in the Philippines, Korea, Japan, Taiwan and China. Many of our customers’ and vendors’ operations are also located outside of the U.S.	
      We provide packaging and test services through our factories located in the Philippines, Korea, Japan, Taiwan and China. Moreover, many of our customers’ and vendors’ operations are located outside the U.S. The following are some of the risks inherent in doing business internationally:
 	 	 	
 	• 	regulatory limitations imposed by foreign governments;	
 	 	 	
 	• 	fluctuations in currency exchange rates;	
 	 	 	
 	• 	political, military and terrorist risks;	
 	 	 	
 	• 	disruptions or delays in shipments caused by customs brokers or government agencies;	
 	 	 	
 	• 	unexpected changes in regulatory requirements, tariffs, customs, duties and other trade barriers;	
 	 	 	
 	• 	difficulties in staffing and managing foreign operations; and	
 	 	 	
 	• 	potentially adverse tax consequences resulting from changes in tax laws.	

 	Difficulties integrating acquisitions — we face challenges as we integrate new and diverse operations and try to attract qualified employees to support our expansion.	
      As a result of our geographic expansion and our business strategy to pursue strategic acquisitions, we have experienced, and expect to continue to experience, growth in the scope and complexity of our operations. For example, each business we have acquired had, at the time of acquisition, multiple systems for managing its own manufacturing, sales, inventory and other operations. Migrating these businesses to our systems typically is a slow, expensive process requiring us to divert significant amounts of resources from multiple aspects of our operations. This growth has strained our managerial, financial, manufacturing and other resources. Future acquisitions and expansions may result in inefficiencies as we integrate new operations and manage geographically diverse operations. Our success depends to a significant extent upon the continued service of our key senior management and technical personnel, any of whom would be difficult to replace. Competition for qualified employees is intense, and our business could be adversely affected by the loss of the services of any of our existing key personnel. Additionally, as part of our ongoing strategic planning, we evaluate our management team and engage in long-term succession planning in order to ensure orderly replacement of key personnel. We cannot assure you that we will be successful in these efforts or in hiring and properly training sufficient numbers of qualified personnel and in effectively managing our growth. Our inability to attract, retain, motivate and train qualified new personnel could have a material adverse effect on our business.

 	Dependence on materials and equipment suppliers — our business may suffer if the cost, quality or supply of materials or equipment changes adversely.	
      We obtain from various vendors the materials and equipment required for the packaging and test services performed by our factories. We source most of our materials, including critical materials such as leadframes,

13

 
laminate substrates and gold wire, from a limited group of suppliers. Furthermore, we purchase all of our materials on a purchase order basis and have no long-term contracts with any of our suppliers. Our business may be harmed if we cannot obtain materials and other supplies from our vendors: (1) in a timely manner, (2) in sufficient quantities, (3) in acceptable quality or (4) at competitive prices.

      Beginning in the second quarter of 2003, we began to experience increases in substrate material costs as a result of supply shortages. Substrate material costs have stabilized at the higher price levels set during the second quarter of 2003. We have significantly enhanced our supply base and do not foresee substrate material availability as an ongoing issue. However, supply shortages may again occur in the future, and in such an event gross margins could be negatively impacted.

      In addition, the average price of gold has been increasing over the past few years. Although we have been able to partially offset the effect of gold price increases through price adjustments to customers and changes in our product designs, gold prices may continue to increase. To the extent that we are unable to offset these increases in the future, our gross margins could be negatively impacted.

 	Capital expenditures — we are required to make substantial capital expenditures, which may adversely affect our business.	
      As customer demand increases, our business requires us to increase our capital expenditures in order to meet increased production requirements. We expect growth in our business in 2004 based on industry estimates for the semiconductor industry as a whole, and our expectation that the trend towards increased outsourcing of packaging and test services in the semiconductor industry will continue. As of April 30, 2004, we spent $221.6 million on capital expenditures, and we expect to spend between $300 million and $500 million in total on capital expenditures in 2004, excluding expenditures on business combinations to diversify our geographic operations and expand our customer base. Our capital expenditure requirements may strain our cash and short-term asset balances, and we expect that the depreciation expenses and, to a lesser extent, factory operating expenses associated with our capital expenditures to increase production capacity, will put downward pressure on our near-term gross margin. In addition, there can be no assurance that we will be able to recognize these expenditures with future revenue.

 	Increased litigation incident to our business — our business may suffer as a result of our involvement in various lawsuits.	
      We are currently a party to various legal proceedings, including those noted below. While we currently believe that the ultimate outcome of these proceedings, individually and in the aggregate, will not have a material adverse effect on our financial position or overall trends in results of operations, litigation is subject to inherent uncertainties. If an unfavorable ruling were to occur, there exists the possibility of a material adverse impact on our net income in the period in which the ruling occurs. The estimate of the potential impact from the following legal proceedings on our financial position or overall results of operations could change in the future.

     EPOXY MOLD COMPOUND LITIGATION

      We have become party to an increased number of litigation matters relative to our historic levels. Much of our recent increase in litigation relates to an allegedly defective epoxy mold compound, formerly used in some of our products, which is alleged to be responsible for certain semiconductor chip failures. In the case of each of these matters, we believe we have meritorious defenses, as well as valid third-party claims against Sumitomo Bakelite Co., Ltd. (“Sumitomo Bakelite”), the manufacturer of the challenged epoxy product, should the epoxy mold compound be found to be defective. We cannot be certain, however, that we will be able to recover any amount from Sumitomo Bakelite if we are held liable in these matters, or that any adverse result would not have a material impact upon us. Moreover, other customers of ours have made inquiries about the epoxy mold compound, which was widely used in the semiconductor industry, and no assurance can be given that claims similar to those already asserted will not be made against us by other customers in the future.

14

 
We incurred legal fees associated with this epoxy mold compound litigation of $4.9 million during the three months ended March 31, 2004, and expect to continue to incur related expenses throughout 2004.

 	• Fujitsu Limited v. Cirrus Logic, Inc., et al.	
      On April 16, 2002, we were served with a third-party complaint in an action entitled Fujitsu Limited v. Cirrus Logic, Inc., No. 02-CV-01627 JW, pending in the United States District Court for the Northern District of California, San Jose Division. In this action, Fujitsu Limited (“Fujitsu”) alleges that semiconductor devices it purchased from Cirrus Logic, Inc. (“Cirrus Logic”) are defective in that a certain epoxy mold compound used in the manufacture of the chip causes a short circuit which renders Fujitsu disk drive products inoperable. Cirrus Logic, in response, denied the allegations of the complaint, counterclaimed against Fujitsu for unpaid invoices, and filed its third-party complaint against us alleging that any liability for chip defects should be assigned to us because we assembled the subject semiconductor devices. Upon receipt of Cirrus Logic’s third-party complaint, we filed an answer denying all liability, and our own third-party complaint against Sumitomo Bakelite. Sumitomo Bakelite filed an answer denying liability. In June 2003, Fujitsu amended its complaint and added direct claims against us. In response, we filed an answer denying all liability to Fujitsu. The parties engaged in discovery activities. Fujitsu has indicated that it may seek damages in excess of $100 million. In November 2003, Fujitsu filed an action against Cirrus Logic, Sumitomo Bakelite and us entitled Fujitsu Limited v. Cirrus Logic, Inc., et al., Case No. 1-03-CV-009885, in the California Superior Court for the County of Santa Clara, based on facts and allegations substantially similar to those asserted in the Northern District Court of California. In December 2003, Cirrus Logic filed a cross-complaint against Sumitomo Bakelite and us in the Superior Court case, also based on facts and allegations substantially similar to those asserted in the Northern District Court case. By stipulation among the parties, the Court has granted a stay of the action pending in the Northern District Court of California in favor of the action pending in the Santa Clara Superior Court, where discovery is ongoing and a trial is scheduled to begin on January 31, 2005. On March 29, 2004, we filed a motion to dismiss Fujitsu’s amended complaint in the Superior Court. On April 2, 2004, we also filed a motion to dismiss Cirrus Logic’s cross-complaint. At the May 4, 2004 hearing on our motions to dismiss, the Court sustained our motion to dismiss in part, and gave Fujitsu and Cirrus Logic thirty days to replead its complaint against us. If necessary, we intend to deny all liability, to file cross-claims against Sumitomo Bakelite, and to seek judgment in our favor in due course.

 	• Seagate Technology LLC v. Atmel Corporation, et al.	
      In March 2003, we were served with a cross-complaint in an action between Seagate Technology LLC and Seagate Technology International (“Seagate”) and Atmel Corporation and Atmel Sarl (“Atmel”) in the Superior Court of California, Santa Clara County, Case No. 1-02-CV809883. Atmel’s cross-complaint seeks indemnification from us for any damages incurred from the claims by Seagate involving the allegedly defective epoxy mold compound manufactured by Sumitomo Bakelite. We answered Atmel’s cross-complaint, denying all liability, and filed a cross-complaint against Sumitomo Bakelite. Atmel later amended its cross-complaint, including adding ChipPAC Inc. (“ChipPAC”) as a cross-defendant. ChipPAC filed a cross-complaint against Sumitomo Bakelite and us. On January 27, 2004, the Superior Court sustained Sumitomo Bakelite’s motion to dismiss Atmel’s amended cross-complaint, granting Atmel 30 days to file an amended pleading. Atmel filed its Second Amended Cross-Complaint on or about March 12, 2004. On April 13, 2004, we filed an answer denying all liability to Atmel. We filed a motion to dismiss ChipPAC’s cross-complaint on February 13, 2004; ChipPAC has indicated its intent to file an amended cross-complaint by April 27, 2004. If appropriate, we may seek to dismiss ChipPAC’s amended pleading, and otherwise intend to deny all liability to ChipPAC. All parties are currently conducting discovery and no trial date has been set.

 	• Maxtor Corporation v. Koninklijke Philips Electronics N.V., et al.	
      In April 2003, we were served with a cross-complaint in an action between Maxtor Corporation (“Maxtor”) and Koninklijke Philips Electronics (“Philips”), in the Superior Court of California, Santa Clara County, Case No. 1-02-CV-808650. Philips’ cross-complaint sought indemnification from us for any damages incurred from the claims by Maxtor involving the allegedly defective epoxy mold compound manufactured by

15

 
Sumitomo Bakelite. Philips subsequently filed a cross-complaint directly against Sumitomo Bakelite, alleging, among other things, that Sumitomo Bakelite breached its contractual obligations to both us and Philips by supplying a defective mold compound resulting in the failure of certain Philips semiconductor devices. We denied all liability in this matter and also asserted a cross-complaint against Sumitomo Bakelite. Sumitomo Bakelite has denied any liability. The parties completed fact discovery and most expert discovery. Maxtor and Philips reached a settlement of Maxtor’s claims against Philips on or about April 28, 2004. Philips and Amkor have publicly announced that they have resolved the dispute between them by means of a settlement agreement stated by the parties on the record before the Court on April 29, 2004. The parties are currently preparing papers to memorialize the settlement. For the three months ended March 31, 2004, we recorded a charge of $1.5 million in Resolution of Legal Dispute in our consolidated statement of income associated with this resolution. The trial of Philips’ claims against Sumitomo Bakelite is scheduled to start on August 2, 2004.

 	• Maxim Integrated Products, Inc. v. Amkor Technology, Inc., et al.	
      In August 2003, we were served with a complaint filed by Maxim Integrated Products, Inc. (“Maxim”) against us, Sumitomo Bakelite and Sumitomo Plastics America, Inc. (“Sumitomo Plastics”) in the Superior Court of California, Santa Clara County, Case No. 1-03-CV-001310. The complaint seeks damages related to our use of Sumitomo Bakelite’s epoxy mold compound in assembling Maxim’s semiconductor packages. Both the Sumitomo defendants and we filed motions to dismiss Maxim’s complaint in September 2003. In lieu of contesting those motions to dismiss, Maxim filed an amended pleading on or about April 26, 2004. We intend to file a motion to dismiss Maxim’s amended complaint, to deny all liability to Maxim and to file cross-claims against Sumitomo Bakelite. Discovery has not commenced and there is no trial date set.

 	• Fairchild Semiconductor Corporation v. Sumitomo Bakelite Singapore Pte. Ltd., et al.	
      In September 2003, we were served with an amended complaint filed by Fairchild Semiconductor Corporation (“Fairchild”) against us, Sumitomo Bakelite, Sumitomo Plastics and Sumitomo Bakelite Singapore Pte. Ltd. in the Superior Court of California, Santa Clara County, Case No. 1-02-CV-810034. The amended complaint seeks damages related to our use of Sumitomo Bakelite’s epoxy mold compound in assembling Fairchild’s semiconductor packages. Both the Sumitomo defendants and we filed motions to dismiss Fairchild’s amended complaint in October 2003. Fairchild filed a second amended complaint in January 2004. On February 11, 2004, we filed a motion to dismiss Fairchild’s second amended complaint. The Superior Court granted our motion to dismiss on March 16, 2004, giving Fairchild thirty days to file a further amended pleading. Fairchild filed a third amended complaint on or about April 15, 2004. We filed a motion to dismiss Fairchild’s third amended pleading on May 17, 2004. We otherwise intend to deny all liability and to file cross-claims against Sumitomo Bakelite. Discovery is ongoing and no trial date has been scheduled.

     OTHER LITIGATION

 	• Amkor Technology, Inc. v. Motorola, Inc.	
      On August 16, 2002, we filed a complaint against Motorola, Inc. in an action captioned Amkor Technology, Inc. v. Motorola, Inc., C.A. No. 02C-08-160 CHT, pending in the Superior Court of the State of Delaware in and for New Castle County. In this action, we were seeking declaratory judgment relating to a controversy between us and Motorola concerning: (i) the assignment by Citizen Watch Co., Ltd. (“Citizen”) to us of a Patent License Agreement dated January 25, 1996 between Motorola and Citizen (the “License Agreement”) and concurrent assignment by Citizen to us of Citizen’s interest in U.S. Patents 5,241,133 and 5,216,278 (the “’133 and ’278 patents”); and (ii) our obligation to make certain payments pursuant to an immunity agreement (the “Immunity Agreement”) dated June 30, 1993 between us and Motorola.

      We and Motorola resolved the controversy with respect to all issues relating to the Immunity Agreement, and all claims and counterclaims filed by the parties in the case relating to the Immunity Agreement were dismissed or otherwise disposed of without further litigation. The claims relating to the License Agreement and the ’133 and ’278 Patents remained pending.

16

 

      We and Motorola both filed motions for summary judgment on the remaining claims, and oral arguments were heard on September 3, 2003. On October 6, 2003, the Superior Court of Delaware ruled in favor of us and issued an Opinion and Order granting our motion for summary judgment and denying Motorola’s motion for summary judgment. On October 22, 2003, Motorola filed an appeal in Supreme Court of Delaware. The appeal was argued on March 9, 2004, and we are awaiting the Court’s decision. We believe we will prevail on the same merits in such appeal. In addition, should Motorola prevail at the appellate level, we believe we have recourse against Citizen. However, no assurance can be given that an adverse outcome in the case cannot occur, or that any adverse outcome would not have a material impact.

 	• Alcatel Business Systems vs. Amkor Technology, Inc., Anam Semiconductor, Inc.	
      On November 5, 1999, we agreed to sell certain semiconductor parts to Alcatel Microelectronics, N.V. (“AME”), a subsidiary of Alcatel S.A. The parts were manufactured for us by Anam Semiconductor, Inc. (“ASI”). AME transferred the parts to another Alcatel subsidiary, Alcatel Business Systems (“ABS”), which incorporated the parts into cellular phone products. In early 2001, a dispute arose as to whether the parts sold by us were defective. On March 18, 2002, ABS and its insurer filed suit against us and ASI in the Paris Commercial Court of France, claiming damages of 50 million Euros (approximately $60.9 million based on the spot exchange rate at March 31, 2004). We have denied all liability and intend to vigorously defend ourselves. Additionally, we have entered into a written agreement with ASI whereby ASI has agreed to indemnify us fully against any and all loss related to the claims of AME, ABS and ABS’ insurer. The Paris Commercial Court commenced a special proceeding before a technical expert to report on the facts of the dispute. The report of the court-appointed expert was put forth on December 31, 2003. The report does not specifically allocate liability to any particular party. A hearing was held on April 28, 2004, and a ruling is expected within 30 days of this date.

      In response to the lawsuit, on May 22, 2002, we filed a petition to compel arbitration in the United States District Court for the Eastern District of Pennsylvania (the “Court”) against ABS, AME and ABS’ insurer, claiming that the dispute is subject to the arbitration clause of the November 5, 1999 agreement between us and AME. ABS and ABS’ insurer have refused to arbitrate. In August 2003, the Court denied the motion of ABS and its insurer to dismiss our petition for arbitration. The Court also subsequently denied a motion for reconsideration filed by ABS. The Court has not yet set a date for final disposition of our petition.

 	• Amkor Technology, Inc. v. Carsem (M) Sdn Bhd, Carsem Semiconductor Sdn Bhd, and Carsem Inc.	
      In November 2003, we filed complaints against Carsem (M) Sdn Bhd, Carsem Semiconductor Sdn Bhd, and Carsem Inc. (collectively “Carsem”) with the International Trade Commission (“ITC”) in Washington, D.C. and subsequently in the Northern District of California. The complaints allege infringement of our United States Patent Nos. 6,433,277, 6,455,356, and 6,630,728 (collectively the “Amkor Patents”). We allege that by making, using, selling, offering for sale, or importing into the U.S. the Carsem Dual and Quad Flat No-Lead Package, Carsem has infringed on one or more of our MicroLeadFrame®packaging technology claims in the Amkor Patents. The District Court action has been stayed pending resolution of the ITC case. The ITC action is scheduled for trial in July 2004.

     	Rapid Technological Change — Our business will suffer if we cannot keep up with the technological advances in our industry.	
      The complexity and breadth of semiconductor packaging and test services are rapidly changing. As a result, we expect that we will need to offer more advanced package designs in order to respond to competitive industry conditions and customer requirements. Our success depends upon our ability to develop and implement new manufacturing processes and package design technologies. The need to develop and maintain advanced packaging capabilities and equipment could require significant research and development and capital expenditures in future years. In addition, converting to new package designs or process methodologies could result in delays in producing new package types that could adversely affect our ability to meet customer orders.

17

 

      Technological advances also typically lead to rapid and significant price erosion and may make our existing products less competitive or our existing inventories obsolete. If we cannot achieve advances in package design or obtain access to advanced package designs developed by others, our business could suffer.

     	Competition — We compete against established competitors in the packaging and test business.	
      The subcontracted semiconductor packaging and test market is very competitive. We face substantial competition from established packaging and test service providers primarily located in Asia, including companies with significant manufacturing capacity, financial resources, research and development operations, marketing and other capabilities. These companies also have established relationships with many large semiconductor companies that are current or potential customers. On a larger scale, we also compete with the internal semiconductor packaging and test capabilities of many of our customers.

     	Environmental Regulations — Future environmental regulations could place additional burdens on our manufacturing operations.	
      The semiconductor packaging process uses chemicals and gases and generates byproducts that are subject to extensive governmental regulations. For example, at our foreign manufacturing facilities, we produce liquid waste when silicon wafers are diced into chips with the aid of diamond saws, then cooled with running water. Federal, state and local regulations in the United States, as well as international environmental regulations, impose various controls on the storage, handling, discharge and disposal of chemicals used in our manufacturing processes and on the factories we occupy.

      Increasingly, public attention has focused on the environmental impact of semiconductor manufacturing operations and the risk to neighbors of chemical releases from such operations. In the future, applicable land use and environmental regulations may: (1) impose upon us the need for additional capital equipment or other process requirements, (2) restrict our ability to expand our operations, (3) subject us to liability or (4) cause us to curtail our operations.

     	Protection of Intellectual Property — We may become involved in intellectual property litigation.	
      We maintain an active program to protect our investment in technology by acquiring intellectual property protection and enforcing our intellectual property rights. Intellectual property rights that apply to our various products and services include patents, copyrights, trade secrets and trademarks. We have filed and obtained a number of patents in the United States and abroad. We expect to continue to file patent applications when appropriate to protect our proprietary technologies, but we cannot assure you that we will receive patents from pending or future applications. In addition, any patents we obtain may be challenged, invalidated or circumvented and may not provide meaningful protection or other commercial advantage to us.

      We may need to enforce our patents or other intellectual property rights or to defend ourselves against claimed infringement of the rights of others through litigation, which could result in substantial cost and diversion of our resources. The semiconductor industry is characterized by frequent claims regarding patent and other intellectual property rights. If any third party makes a valid claim against us, we could be required to:
 	 	 	
 	• 	discontinue the use of certain processes;	
 	 	 	
 	• 	cease the manufacture, use, import and sale of infringing products;	
 	 	 	
 	• 	pay substantial damages;	
 	 	 	
 	• 	develop non-infringing technologies; or	
 	 	 	
 	• 	acquire licenses to the technology we had allegedly infringed.	
      If we fail to obtain necessary licenses or if we face litigation relating to patent infringement or other intellectual property matters, our business could suffer.

18

 

 	Continued Control by Existing Stockholders — Mr. James Kim and members of his family can substantially control the outcome of all matters requiring stockholder approval.	
      As of May 1, 2004, Mr. James Kim and members of his family beneficially owned approximately 42% of our outstanding common stock. Mr. James Kim’s family, acting together, will substantially control all matters submitted for approval by our stockholders. These matters could include:
 	 	 	
 	• 	the election of all of the members of our board of directors;	
 	 	 	
 	• 	proxy contests;	
 	 	 	
 	• 	mergers involving our company;	
 	 	 	
 	• 	tender offers; and	
 	 	 	
 	• 	open market purchase programs or other purchases of our common stock.

You are cautioned not to place undue reliance on these forward-looking statements, which speak only as of the date of this prospectus or, as applicable, as of the date of any such document incorporated by reference herein. Moreover, in the future, we may make forward-looking statements about the matters described in this prospectus or about other matters concerning us.

PRIVATE PLACEMENT

      We issued $250 million in principal amount of the original notes dated as of March 12, 2004 to the initial purchasers of those notes and received proceeds that after deducting expenses and commissions represented an aggregate of $245.2 million in net proceeds. We issued the original notes to the initial purchasers in a transaction exempt from or not subject to registration under the Securities Act. The initial purchasers then offered and resold the original notes to qualified institutional buyers in compliance with Rule 144A or non-U.S. persons in compliance with Regulation S under the Securities Act.

USE OF PROCEEDS

      We are making the exchange offer to satisfy our obligations under the Registration Rights Agreement that we entered into in connection with the private offering of the original notes. We will not receive any cash proceeds from the issuance of the exchange notes. In consideration of issuing the exchange notes in the exchange offer, we will receive an equal principal amount of original notes. Any original notes that are properly tendered and accepted in the exchange offer will be canceled and retired and cannot be reissued. As a result, the issuance of the exchange notes will not result in any increase or decrease in our outstanding indebtedness.

THE EXCHANGE OFFER

Purpose and Effect of the Exchange Offer

      On March 12, 2004, we sold $250 million in aggregate principal amount at maturity of the original notes in a private placement. The original notes were sold to the initial purchasers who in turn resold the notes to a limited number of “Qualified Institutional Buyers,” as defined under the Securities Act, and to non-U.S. persons in transactions outside the United States in reliance on Regulation S of the Securities Act. In connection with the sale of the original notes, we entered into a Registration Rights Agreement with the initial purchasers of the original notes. A copy of the Registration Rights Agreement has been filed as an exhibit to our Quarterly Report on Form 10-Q for the quarter ended March 31, 2004, which is incorporated by reference herein.

      Under the Registration Rights Agreement, we have agreed to file a registration statement regarding the exchange of the original notes for the exchange notes which are registered under the Securities Act. We have also agreed to use our commercially reasonable efforts to cause the registration statement to become effective with the SEC by October 8, 2004. For a more detailed explanation of our obligations under the Registration Rights Agreement, see the section entitled “Description of Notes — Registration Rights; Liquidated Damages.”

      In order to participate in the exchange offer, you must represent to us, among other things, that:
 	 	 	
 	• 	you are acquiring the exchange notes in the exchange offer in the ordinary course of your business;	
 	 	 	
 	• 	you are not engaged in, and do not intend to engage in, a distribution of the exchange notes;	
 	 	 	
 	• 	you do not have any arrangement or understanding with any person to participate in the distribution of the exchange notes;	
 	 	 	
 	• 	you are not a broker-dealer tendering original notes acquired directly from us for your own account; and	
 	 	 	
 	• 	you are not one of our “affiliates,” as defined in Rule 405 of the Securities Act.	
Resale of the Exchange Notes

      Based on interpretations by the Staff of the SEC set forth in no-action letters issued to third parties, including Exxon Capital Holdings Corporation (available May 13, 1988) and Morgan Stanley & Co. Incorporated (available June 5, 1991), we believe that the exchange notes issued in the exchange offer may be offered for resale, resold and otherwise transferred by you, except if you are an affiliate of us, without compliance with the registration and prospectus delivery provisions of the Securities Act, provided that the representations set forth in “— Purpose and Effect of the Exchange Offer” apply to you.

      If:
 	 	 	
 	• 	you are a broker-dealer; or	
 	 	 	
 	• 	you acquire exchange notes in the exchange offer for the purpose of distributing or participating in the distribution of the exchange notes, you cannot rely on the position of the staff of the SEC contained in the no-action letters mentioned above and must comply with the registration and prospectus delivery requirements of the Securities Act in connection with any resale transaction, unless an exemption from registration is otherwise available.	
      Each broker-dealer that receives exchange notes for its own account in exchange for private notes, which the broker-dealer acquired as a result of market-making activities or other trading activities, must acknowledge that it will deliver a prospectus in connection with any resale of the exchange notes. The letter of transmittal states that 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. A broker-dealer may use this prospectus, as it may be amended or supplemented from time to time, in connection with the resales of

21

 
exchange notes received in exchange for private notes which the broker-dealer acquired as a result of market-making or other trading activities. Any holder that is a broker-dealer participating in the exchange offer must notify the exchange agent at the telephone number set forth in the enclosed letter of transmittal and must comply with the procedures for broker-dealers participating in the exchange offer. We have not entered into any arrangement or understanding with any person to distribute the exchange notes to be received in the exchange offer. The exchange offer is not being made to, nor will we accept surrenders for exchange from, holders of original notes in any jurisdiction in which the exchange offer or the acceptance thereof would not be in compliance with the securities or blue sky laws of the particular jurisdiction.

Terms of the Exchange Offer

      This prospectus and the accompanying letter of transmittal together constitute the exchange offer. Upon the terms and subject to the conditions set forth in this prospectus and in the letter of transmittal, we will accept original notes for exchange which are properly tendered on or before the expiration date and are not withdrawn as permitted below. The expiration date for this exchange offer is 5:00 p.m., New York City time, on July 6, 2004, or such later date and time to which we, in our sole discretion, extend the exchange offer, subject to applicable law.

      As of the date of this prospectus, $250 million in aggregate principal amount at maturity of the original notes are outstanding. This prospectus and the letter of transmittal are being sent to all registered holders of the original notes on this date. There will be no fixed record date for determining registered holders of the original notes entitled to participate in the exchange offer. However, holders of the original notes must cause their original notes to be tendered by book-entry transfer or tender their certificates for the original notes before the expiration date of the exchange offer in order to participate in the exchange offer.

      The form and terms of the exchange notes being issued in the exchange offer are the same as the form and terms of the original notes, except that:
 	 	 	
 	• 	the exchange notes being issued in the exchange offer will have been registered under the Securities Act;	
 	 	 	
 	• 	the exchange notes being issued in the exchange offer will not bear the restrictive legends restricting their transfer under the Securities Act; and	
 	 	 	
 	• 	the exchange notes being issued in the exchange offer will not contain the registration rights and provisions for liquidated damages contained in the original notes.	
      The exchange notes will evidence the same debt as the original notes and will be issued under the same Indenture, so the exchange notes and the original notes will be treated as a single class of debt securities under the Indenture.

      Outstanding notes being tendered in the exchange offer must be in integral multiples of $1,000. We will issue $1,000 principal amount of exchange notes in exchange for each $1,000 principal amount of outstanding notes surrendered pursuant to the exchange offer.

      We intend to conduct the exchange offer in accordance with the provisions of the Registration Rights Agreement and applicable federal securities laws. Original notes that are not tendered for exchange in the exchange offer will remain outstanding and will be entitled to the rights under the Indenture. Any original notes not tendered for exchange will not retain any rights under the Registration Rights Agreement and will remain subject to transfer restrictions. See “— Consequences of Failure to Exchange.”

      We will be deemed to have accepted for exchange validly tendered original notes when, as and if we have given oral or written notice of our acceptance of the validly tendered original notes to the exchange agent. The exchange agent will act as agent for the tendering holders for the purposes of receiving the exchange notes from us. If any tendered original notes are not accepted for exchange because of an invalid tender or the occurrence of other events set forth in this prospectus or otherwise, certificates for any unaccepted original notes will be returned, or, in the case of original notes tendered by book-entry transfer, those unaccepted original notes will be credited to an account maintained with DTC, without expense to the tendering

22

 
holder of those original notes as promptly as practicable after the expiration date of the exchange offer. See “— Procedures for Tendering.”

      Those who tender original notes in the exchange offer will not be required to pay brokerage commissions or fees or, subject to the instructions in the letter of transmittal, transfer taxes with respect to the exchange of original notes in the exchange offer. We will pay all charges and expenses, other than applicable taxes described below, in connection with the exchange offer. See “— Fees and Expenses” and “— Transfer Taxes.”

Expiration Date; Extensions, Amendments

      The exchange offer will expire at 5:00 p.m., New York City time, on July 6, 2004, or such later date and time to which we, in our sole discretion, extend the exchange offer, subject to applicable law. In case of an extension of the expiration date of the exchange offer, we will issue a press release or other public announcement no later than 9:00 a.m., New York City time, on the next business day after the previously scheduled expiration date. During any such extension, all original notes you have previously tendered and not withdrawn will remain subject to the exchange offer, and we may accept them for exchange.

Conditions to the Completion of the Exchange Offer

      We may not accept original notes for exchange and may terminate or not complete the exchange offer if:
 	 	 	
 	• 	any action, proceeding or litigation seeking to enjoin, make illegal or delay completion of the exchange offer or otherwise relating in any manner to the exchange offer is instituted or threatened;	
 	 	 	
 	• 	any order, stay, judgment or decree is issued by any court, government, governmental authority or other regulatory or administrative authority and is in effect, or any statute, rule, regulation, governmental order or injunction shall have been proposed, enacted, enforced or deemed applicable to the exchange offer, any of which would or might restrain, prohibit or delay completion of the exchange offer or impair the contemplated benefits of the exchange offer to us;	
 	 	 	
 	• 	any of the following occurs and the adverse effect of such occurrence shall, in our reasonable judgment, be continuing:	

 	• 	any general suspension of trading in, or limitation on prices for, securities on any national securities exchange or in the over-the-counter market in the United States;	
 	 	 	
 	• 	any extraordinary or material adverse change in U.S. financial markets generally, including, without limitation, a decline of at least 10% in either the Dow Jones Industrial Average, the NASDAQ Index or the Standard & Poor’s 500 Index from the date of commencement of the exchange offer;	
 	 	 	
 	• 	a declaration of a banking moratorium or any suspension of payments in respect of banks in the United States;	
 	 	 	
 	• 	any limitation, whether or not mandatory, by any governmental entity on, or any other event that would reasonably be expected to materially adversely affect, the extension of credit by banks or other lending institutions;	
 	 	 	
 	• 	a commencement of a war or other national or international calamity directly or indirectly involving the United States, which would reasonably be expected to affect materially or adversely, or to delay materially, the completion of the exchange offer; or	
 	 	 	
 	• 	if any of the situations described above existed at the time of commencement of the exchange offer and that situation deteriorates materially after commencement of the exchange offer;	

 	• 	any tender or exchange offer, other than this exchange offer by us, with respect to some or all of our outstanding common stock or any merger, acquisition or other business combination proposal involving us shall have been proposed, announced or made by any person or entity;	
 	 	 	
 	• 	any event or events occur that have resulted or may result, in our reasonable judgment, in a material adverse change in our business or financial condition; or	
23

 
 	 	 	
 	• 	as the term “group” is used in Section 13(d)(3) of the Exchange Act:	

 	• 	any person, entity or group acquires more than 5% of our outstanding shares of common stock, other than a person, entity or group which had publicly disclosed such ownership with the SEC prior to the date of commencement of the exchange offer;	
 	 	 	
 	• 	any such person, entity or group which had publicly disclosed such ownership prior to such date shall acquire additional common stock constituting more than 2% of our outstanding shares;	
 	 	 	
 	• 	any new group shall have formed that beneficially owns more than 5% of our outstanding shares of common stock that in our judgment in any such case, and regardless of the circumstances, makes it inadvisable to proceed with the exchange offer or with such acceptance for exchange of existing notes;	

 	• 	any stop order is threatened or in effect with respect to the registration statement of which this prospectus constitutes a part or the qualification of the Indenture under the Trust Indenture Act of 1939;	
 	 	 	
 	• 	any governmental approval or approval by holders of the original notes has not been obtained if we, in our reasonable judgment, deem this approval necessary for the consummation of the exchange offer; or	
 	 	 	
 	• 	there occurs a change in the current interpretation by the Staff of the SEC which permits the exchange notes to be issued in the exchange offer to be offered for resale, resold and otherwise transferred by the holders of the exchange notes, other than broker-dealers and any holder which is an “affiliate” of ours within the meaning of Rule 405 under the Securities Act, without compliance with the registration and prospectus delivery provisions of the Securities Act, provided that the exchange notes acquired in the exchange offer are acquired in the ordinary course of that holder’s business and that holder has no arrangement or understanding with any person to participate in the distribution of the exchange notes to be issued in the exchange offer.	
      If any of the above events occur, we may:
 	 	 	
 	• 	terminate the exchange offer and promptly return all tendered original notes to tendering holders;	
 	 	 	
 	• 	complete and/or extend the exchange offer and, subject to your withdrawal rights, retain all tendered original notes until the extended exchange offer expires;	
 	 	 	
 	• 	amend the terms of the exchange offer; or	
 	 	 	
 	• 	waive any unsatisfied condition and, subject to any requirement to extend the period of time during which the exchange offer is open, complete the exchange offer.	
      We may assert these conditions with respect to the exchange offer regardless of the circumstances giving rise to them. All conditions to the exchange offer, other than those dependent upon receipt of necessary government approvals, must be satisfied or waived by us before the expiration of the exchange offer. We may waive any condition in whole or in part at any time in our reasonable discretion. Our failure to exercise our rights under any of the above circumstances does not represent a waiver of these rights. Each right is an ongoing right that may be asserted at any time. Any determination by us concerning the conditions described above will be final and binding upon all parties.

      If a waiver constitutes a material change to the exchange offer, we will promptly disclose the waiver by means of a prospectus supplement that we will distribute to the registered holders of the original notes, and we will extend the exchange offer for a period of five to ten business days, as required by applicable law, depending upon the significance of the waiver and the manner of disclosure to the registered holders, if the exchange offer would otherwise expire during the five to ten business day period.

Procedures for Tendering

      To effectively tender original notes by book-entry transfer to the account maintained by the exchange agent at DTC, holders of original notes must request a DTC participant to, on their behalf, in lieu of physically

24

 
completing and signing the letter of transmittal and delivering it to the exchange agent, electronically transmit their acceptance through DTC’s Automated Tender Offer Program (“ATOP”). DTC will then edit and verify the acceptance and send an agent’s message to the exchange agent for its acceptance. An “agent’s message” is a message transmitted by DTC to, and received by, the exchange agent and forming a part of the Book-Entry Confirmation (as defined below), which states that DTC has received an express acknowledgment from the DTC participant tendering original notes on behalf of the holder of such original notes that such DTC participant has received and agrees to be bound by the terms and conditions of the exchange offer as set forth in this prospectus and the related letter of transmittal and that we may enforce such agreement against such participant. A timely confirmation of a book-entry transfer of the original notes into the exchange agent’s account at DTC (a “Book-Entry Confirmation”), pursuant to the book-entry transfer procedures described below, as well as an agent’s message pursuant to DTC’s ATOP system must be mailed or delivered to the exchange agent on or prior to 5:00 p.m., New York City time, on the expiration date.

      To effectively tender any original notes held in physical form, a holder of the original notes must complete, sign and date the letter of transmittal, or a facsimile thereof, have the signatures thereon guaranteed if required by the letter of transmittal, and mail or otherwise deliver such letter of transmittal or a facsimile thereof, together with the certificates representing such original notes and any other required documents, to the exchange agent prior to 5:00 p.m., New York City time, on the expiration date.

      Holders of original notes whose certificates for original notes are not lost but are not immediately available or who cannot deliver their certificates and all other documents required by the letter of transmittal to the exchange agent on or prior to the expiration date, or who cannot complete the procedures for book-entry transfer on or prior to the expiration date, may tender their original notes according to the guaranteed delivery procedures set forth in “— Guaranteed Delivery Procedures” below.

      The method of delivery of the letter of transmittal, any required signature guarantees, the original notes and all other required documents, including delivery of original notes through DTC, and transmission of an agent’s message through DTC’s ATOP system, is at the election and risk of the tendering holders, and the delivery will be deemed made only when actually received or confirmed by the exchange agent. If original notes are sent by mail, it is suggested that the mailing be registered mail, properly insured, with return receipt requested, made sufficiently in advance of the expiration date, as desired, to permit delivery to the exchange agent prior to 5:00 p.m. on the expiration date. Holders tendering original notes through DTC’s ATOP system must allow sufficient time for completion of the ATOP procedures during the normal business hours of DTC on such respective date.

      No original notes, agent’s messages, letters of transmittal or other required documents should be sent to us. Delivery of all original notes, agent’s messages, letters of transmittal and other documents must be made to the exchange agent. Holders may also request their respective brokers, dealers, commercial banks, trust companies or nominees to effect such tender for such holders.

      The tender by a holder of original notes, including pursuant to the delivery of an agent’s message through DTC’s ATOP system, will constitute an agreement between such holder and us in accordance with the terms and subject to the conditions set forth herein and in the letter of transmittal.

      Holders of original notes registered in the name of a broker, dealer, commercial bank, trust company or other nominee who wish to tender must contact such registered holder promptly and instruct such registered holder how to act on such non-registered holder’s behalf.

      Signatures on a letter of transmittal or a notice of withdrawal must be guaranteed by a member firm of a registered national securities exchange or of the National Association of Securities Dealers, Inc., a commercial bank or trust company having an office or correspondent in the United States or an “eligible guarantor institution” within the meaning of Rule 17Ad-15 under the Exchange Act (each an “eligible

25

 
institution”) unless the original notes tendered pursuant to the letter of transmittal or a notice of withdrawal are tendered:
 	 	 	
 	• 	by a registered holder of original notes who has not completed the box entitled “Special Issuance Instructions” or “Special Delivery Instructions” on the letter of transmittal, or	
 	 	 	
 	• 	for the account of an eligible institution.	
      If a letter of transmittal is signed by trustees, executors, administrators, guardians, attorneys-in-fact, officers of corporations or others acting in a fiduciary or representative capacity, such person should so indicate when signing, and, unless waived by us, evidence satisfactory to us of their authority to so act must be submitted with such letter of transmittal.

      If the letter of transmittal is signed by a person other than the registered holder, the original notes must be endorsed or accompanied by a properly completed bond power, signed by the registered holder as the registered holders’ name appears on the original notes.

      All questions as to the validity, form, eligibility, time of receipt, acceptance and withdrawal of the tendered original notes will be determined by us in our sole discretion, which determination will be final and binding. We reserve the absolute right to reject any and all original notes not validly tendered or any original notes which, if accepted, might, in the opinion of our counsel, be unlawful. We also reserve the absolute right to waive any irregularities or conditions of tender as to particular original notes. Our interpretation of the terms and conditions of this exchange offer, including the letter of transmittal and the instructions thereto, shall be final and binding on all parties. Unless waived, any defects or irregularities in connection with tenders of original notes must be cured within such time as we shall determine. Although we intend to notify you of defects or irregularities with respect to tenders of original notes, none of us, the exchange agent, or any other person shall be under any duty to give notification of defects or irregularities with respect to tenders of original notes, nor shall any of them incur any liability for failure to give such notification. Tenders of original notes will not be deemed to have been made until such irregularities have been cured or waived. Any original notes received by the exchange agent that are not validly tendered and as to which the defects or irregularities have not been cured or waived will be returned without cost to such holder by the exchange agent, unless otherwise provided in the letter of transmittal, as soon as practicable following the expiration date of the exchange offer.

      Although we have no present plan to acquire any original notes that are not tendered in the exchange offer or to file a registration statement to permit resales of any original notes that are not tendered in the exchange offer, we reserve the right, in our sole discretion, to purchase or make offers for any original notes after the expiration date of the exchange offer, from time to time, through open market or privately negotiated transactions, one or more additional exchange or tender offers, or otherwise, as permitted by law, the Indenture and our other debt agreements. Following consummation of this exchange offer, the terms of any such purchases or offers could differ materially from the terms of this exchange offer.

      By tendering, each holder will represent to us that, among other things:
 	 	 	
 	• 	it is not an affiliate of ours;	
 	 	 	
 	• 	the person acquiring the exchange notes in the exchange offer is obtaining them in the ordinary course of its business, whether or not such person is the holder, and	
 	 	 	
 	• 	neither the holder nor such other person has any arrangement or understanding with any person to participate in the distribution of the exchange notes issued in the exchange offer.	
      If any holder or any such other person is an “affiliate,” as defined under Rule 405 of the Securities Act, of us, or is engaged in or intends to engage in or has an arrangement or understanding with any person to participate in a distribution of exchange notes to be acquired in the exchange offer, that holder or any such other person:
 	 	 	
 	• 	may not rely on the applicable interpretations of the staff of the SEC; and	
 	 	 	
 	• 	must comply with the registration and prospectus delivery requirements of the Securities Act in connection with any resale transaction.	
26

 

      Each broker-dealer who acquired its original notes as a result of market-making activities or other trading activities, and thereafter receives exchange notes issued for its own account in the exchange offer, must acknowledge that it will deliver a prospectus in connection with any resale of such exchange notes issued in the exchange offer. The letter of transmittal states that 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. See “Plan of Distribution” for a discussion of the exchange and resale obligations of broker-dealers in connection with the exchange offer.

Acceptance of Original Notes for Exchange; Delivery of Exchange Notes Issued in the Exchange Offer

      Upon satisfaction or waiver of all of the conditions to the exchange offer, we will accept, promptly after the expiration date, all original notes properly tendered and not withdrawn, and will issue exchange notes registered under the Securities Act. For purposes of the exchange offer, we will be deemed to have accepted properly tendered original notes for exchange when, as and if we have given oral or written notice to the exchange agent, with written confirmation of any oral notice to be given promptly thereafter. See “— Conditions to the Completion of the Exchange Offer” for a discussion of the conditions that must be satisfied before we accept any original notes for exchange.

      For each original note accepted for exchange, the holder will receive an exchange note registered under the Securities Act having a principal amount equal to that of the surrendered original note. As a result, registered holders of exchange notes issued in the exchange offer on the relevant record date for the first interest payment date following the completion of the exchange offer will receive interest accruing from the most recent date to which interest has been paid or, if no interest has been paid on the original notes, from March 12, 2004. Original notes that we accept for exchange will cease to accrue interest from and after the date of completion of the exchange offer. Under the Registration Rights Agreement, we may be required to make additional payments in the form of liquidated damages to the holders of the original notes under circumstances relating to the timing of the exchange offer.

      In all cases, we will issue exchange notes in the exchange offer for original notes that are accepted for exchange only after the exchange agent timely receives:
 	 	 	
 	• 	certificates for such original notes or a book-entry confirmation of such original notes into the exchange agent’s account at DTC;	
 	 	 	
 	• 	an agent’s message or a properly completed and duly executed letter of transmittal; and/or	
 	 	 	
 	• 	any other required documents.	
      If for any reason set forth in the terms and conditions of the exchange offer we do not accept any tendered original notes, or if a holder submits original notes for a greater principal amount than the holder desires to exchange or a holder withdraws original notes, we will return such unaccepted, non-exchanged or withdrawn original note without cost to the tendering holder. In the case of original notes tendered by book-entry transfer into the exchange agent’s account at DTC, such non-exchanged original notes will be credited to an account maintained with DTC. We will return the original notes or have them credited to the DTC account as promptly as practicable after the expiration or termination of the exchange offer.

Book-Entry Transfer

      The exchange agent will establish an account with respect to the original notes at DTC for purposes of this exchange offer. Any financial institution that is a participant in DTC’s ATOP systems may use DTC’s ATOP procedures to tender original notes. Such participant may make a book-entry delivery of original notes by causing DTC to transfer such original notes into the exchange agent’s account at DTC in accordance with DTC’s procedures for transfer. However, although delivery of original notes may be effected through a book-entry transfer at DTC, the letter of transmittal, or facsimile thereof, with any required signature guarantees, or an agent’s message pursuant to the ATOP procedures and any other required documents must, in any case, be transmitted to and received by the exchange agent at the address set forth in this prospectus on or prior to the

27

 
expiration date of the exchange offer, or the guaranteed delivery procedures described below must be complied with. Delivery of documents to DTC will not constitute valid delivery to the exchange agent.

Guaranteed Delivery Procedures

      If your certificates for original notes are not lost but are not immediately available or you cannot deliver your certificates and any other required documents to the exchange agent on or prior to the expiration date, or you cannot complete the procedures for book-entry transfer on or prior to the expiration date, you may nevertheless effect a tender of your original notes if:
 	 	 	
 	• 	the tender is made through an eligible institution;	
 	 	 	
 	• 	prior to the expiration date of the exchange offer, the exchange agent receives by facsimile transmission, mail or hand delivery from such eligible institution a validly completed and duly executed notice of guaranteed delivery, substantially in the form provided with this prospectus, or an agent’s message with respect to guaranteed delivery which:	

 	• 	sets forth your name and address and the amount of your original notes tendered;	
 	 	 	
 	• 	states that the tender is being made thereby; and	
 	 	 	
 	• 	guarantees that within three New York Stock Exchange trading days after the expiration date, the certificates for all physically tendered original notes, in proper form for transfer, or a book-entry confirmation, as the case may be, and any other documents required by the letter of transmittal will be deposited by the eligible institution with the exchange agent; and	

 	• 	the certificates for all physically tendered original notes, in proper form for transfer, or a book-entry confirmation, as the case may be, and all other documents required by the letter of transmittal are received by the exchange agent within three New York Stock Exchange trading days after the expiration date.	
Withdrawal of Tenders

      Tenders of original notes may be properly withdrawn at any time prior to 5:00 p.m., New York City time, on the expiration date.

      For a withdrawal of a tender to be effective, a written notice of withdrawal delivered by hand, overnight by courier or by mail, or a manually signed facsimile transmission, or a properly transmitted “Request Message” through DTC’s ATOP system, must be received by the exchange agent prior to 5:00 p.m., New York City time, on the expiration date. Any such notice of withdrawal must:
 	 	 	
 	• 	specify the name of the person that tendered the original notes to be properly withdrawn;	
 	 	 	
 	• 	identify the original notes to be properly withdrawn, including the principal amount of such original notes;	
 	 	 	
 	• 	in the case of original notes tendered by book-entry transfer, specify the number of the account at DTC from which the original notes were tendered and specify the name and number of the account at DTC to be credited with the properly withdrawn original notes and otherwise comply with the procedures of such facility;	
 	 	 	
 	• 	contain a statement that such holder is withdrawing its election to have such original notes exchanged for exchange notes;	
 	 	 	
 	• 	other than a notice transmitted through DTC’s ATOP system, be signed by the holder in the same manner as the original signature on the letter of transmittal by which such original notes were tendered, including any required signature guarantees, or be accompanied by documents of transfer to have the trustee with respect to the original notes register the transfer of such original notes in the name of the person withdrawing the tender; and	
 	 	 	
 	• 	specify the name in which such original notes are registered, if different from the person who tendered such original notes.	
28

 

      All questions as to the validity, form, eligibility and time of receipt of such notice will be determined by us, and our determination shall be final and binding on all parties. Any original notes so properly withdrawn will be deemed not to have been validly tendered for exchange for purposes of this exchange offer. No exchange notes will be issued with respect to any withdrawn original notes unless the original notes so withdrawn are later tendered in a valid fashion. Any original notes that have been tendered for exchange but are not exchanged for any reason will be returned to the tendering holder thereof without cost to such holder, or, in the case of original notes tendered by book-entry transfer into the exchange agent’s account at DTC pursuant to the book-entry transfer procedures described above, such original notes will be credited to an account maintained with DTC for the original notes as soon as practicable after withdrawal, rejection of tender or termination of the exchange offer. Properly withdrawn original notes may be retendered by following the procedures described above at any time on or prior to the expiration date of the exchange offer.

Exchange Agent

      Wells Fargo Bank, National Association has been appointed as exchange agent for this exchange offer. Letters of transmittal, agent’s messages or request messages through DTC’s ATOP system, notices of guaranteed delivery and all correspondence in connection with this exchange offer should be sent or delivered by each holder of original notes or a beneficial owner’s broker, dealer, commercial bank, trust company or other nominee to the exchange agent at the following address: Wells Fargo Bank, National Association, Corporate Trust Operations, MAC N9303-121, Sixth Street and Marquette Avenue, Minneapolis, MN 55479, Attention: Joe Taffe, telephone: (612) 667-6961, facsimile: (612) 667-9825. Requests for information or documents relating to the exchange offer may also be directed to the exchange agent by calling (800) 344-5128. We will pay the exchange agent reasonable and customary fees for its services and will reimburse it for its reasonable out-of-pocket expenses in connection therewith. Delivery or facsimile to a party other than the exchange agent will not constitute valid delivery.

Fees and Expenses

          We Will Bear The Expenses Of Soliciting Tenders. The Principal Solicitation Is Being Made by Mail; However, We May Make Additional Solicitation By Facsimile, E mail, Telephone Or In Person By Our Officers And Regular Employees And Those Of Our Affiliates.

      We have not retained any dealer-manager in connection with the exchange offer and will not make any payments to broker-dealers or others soliciting acceptances of the exchange offer. We will, however, pay the exchange agent reasonable and customary fees for its services and reimburse it for its related reasonable out-of-pocket expenses. We may also pay brokerage houses and other custodians, nominees and fiduciaries the reasonable out-of-pocket expenses incurred by them in forwarding copies of this prospectus, letters of transmittal and related documents to the beneficial owners of the original notes and in handling or forwarding tenders for exchange.

      We will pay the cash expenses to be incurred in connection with the exchange offer. They include:
 	 	 	
 	• 	SEC registration fees for the exchange notes,	
 	 	 	
 	• 	fees and expenses of the exchange agent and the Trustee,	
 	 	 	
 	• 	accounting and legal fees,	
 	 	 	
 	• 	printing costs, and	
 	 	 	
 	• 	related fees and expenses.	
Transfer Taxes

      If you tender your original notes for exchange, you will not be required to pay any transfer taxes. We will pay all transfer taxes, if any, applicable to the exchange of original notes in the exchange offer. The tendering

29

 
holder will, however, be required to pay any transfer taxes, whether imposed on the registered holder or any other person, if:
 	 	 	
 	• 	certificates representing exchange notes or original notes for principal amounts not tendered or accepted for exchange are to be delivered to, or are to be issued in the name of, any person other than the registered holder of the original notes tendered,	
 	 	 	
 	• 	tendered original notes are registered in the name of any person other than the person signing the letter of transmittal, or	
 	 	 	
 	• 	a transfer tax is imposed for any reason other than the exchange of original notes for exchange notes in the exchange offer.	
      If satisfactory evidence of payment of any transfer taxes payable by a tendering holder is not submitted with the letter of transmittal, the amount of such transfer taxes will be billed directly to that tendering holder. The exchange agent will retain possession of exchange notes with a face amount equal to the amount of the transfer taxes due until it receives payment of the taxes.

Consequences of Failure to Exchange

      Holders who desire to tender their original notes in exchange for exchange notes registered under the Securities Act should allow sufficient time to ensure timely delivery. Neither the exchange agent nor us is under any duty to give notification of defects or irregularities with respect to the tenders of original notes for exchange.

      Original notes that are not tendered or are tendered but not accepted will, following the completion of the exchange offer, continue to be subject to the provisions in the Indenture regarding the transfer and exchange of the original notes and the existing restrictions on transfer set forth in the legend on the original notes set forth in the Indenture for the notes. Except in limited circumstances with respect to specific types of holders of original notes, we will have no further obligation to provide for the registration under the Securities Act of such original notes. In general, original notes, unless registered under the Securities Act, may not be offered or sold except pursuant to an exemption from, or in a transaction not subject to, the Securities Act and applicable state securities laws.

      We do not currently anticipate that we will take any action to register the original notes under the Securities Act or under any state securities laws. Upon completion of the exchange offer, holders of the original notes will not be entitled to any further registration rights under the Registration Rights Agreement, except under limited circumstances.

      Holders of the exchange notes issued in the exchange offer and any original notes which remain outstanding after completion of the exchange offer will vote together as a single class for purposes of determining whether holders of the requisite percentage of the class have taken certain actions or exercised certain rights under the Indenture.

      The tender of original notes in the exchange offer will reduce the outstanding principal amount of the original notes. Due to the corresponding reduction in liquidity, this may have an adverse effect on, and increase the volatility of, the market price of any original notes that you continue to hold.

Other

      Participation in the exchange offer is voluntary, and you should carefully consider whether to accept. You are urged to consult your financial and tax advisors in making your decision on what action to take. In the future, we may seek to acquire untendered original notes in open market or privately negotiated transactions, through subsequent exchange offers or otherwise. We have no present plan to acquire any original notes that are not tendered in the exchange offer or to file a registration statement to permit resales of any untendered original notes, except as required by the Registration Rights Agreement.

DESCRIPTION OF THE NOTES

      You can find the definitions of certain terms used in this description under the caption “— Certain Definitions.” In this description, the word “Amkor” refers only to Amkor Technology, Inc. and not to any of its Subsidiaries and the term “Notes” refers to both the original notes and the exchange notes.

      Amkor will issue the exchange notes under the Indenture (the “Indenture”) between itself and Wells Fargo Bank, National Association, as trustee (the “Trustee”). The terms of the Notes include those stated in the Indenture and those made part of the Indenture by reference to the Trust Indenture Act of 1939.

      The following description is a summary of the material provisions of the Indenture. It does not restate that agreement in its entirety. We urge you to read the Indenture because it, and not this description, defines your rights as holders of the Notes. Copies of the Indenture are available as described below under the caption “Available Information.”

Ranking

      The Notes are:
 	 	 	
 	• 	general obligations of Amkor;	
 	 	 	
 	• 	effectively subordinated in right of payment to existing and future secured debt, if any, including our obligations under our secured bank facilities, to the extent of such security, and to all existing and future debt and other liabilities of our subsidiaries, including trade payables;	
 	 	 	
 	• 	equal in right of payment with all our existing and future unsecured senior debt, including our 9.25% senior notes due February 15, 2008 and our 7.75% senior notes due May 15, 2013; and	
 	 	 	
 	• 	senior in right of payment to all our existing and future debt that expressly provides that it is subordinated to the Notes, including our 10.50% senior subordinated notes due 2009, our 5.75% convertible subordinated notes due 2006 and our 5.00% convertible subordinated notes due 2007.	
      The Notes are “Designated Senior Debt” for purposes of the indentures governing our 10.50% senior subordinated notes due 2009, our 5.75% convertible subordinated notes due 2006 and our 5.00% convertible subordinated notes due 2007.

      As of March 31, 2004, Amkor had total senior secured debt of $1.6 million. In addition, our subsidiaries had total liabilities of approximately $381.0 million, including trade payables but excluding intercompany obligations. The Indenture will permit us to incur additional senior secured debt and subsidiary indebtedness subject to certain restrictions as outlined in the indenture. See “— Incurrence of Indebtedness and Issuance of Preferred Stock” beginning on page 37.

      We conduct a large portion of our operations through our Subsidiaries. Accordingly, our ability to meet our cash obligations is dependent upon the ability of our Subsidiaries to make cash payments to us. Payments from our Subsidiaries are expected to be a large source of funds for payment of interest on the Notes. The claims of creditors (including trade creditors) of any Subsidiary will generally have priority as to the assets of such Subsidiary over the claims of the holders of the Notes. In the event of a liquidation of any of our Subsidiaries, our right to receive the assets of any such Subsidiary (and the resulting right of the holders of the Notes to participate in the distribution of the proceeds of those assets) will effectively be subordinated by operation of law to the claims of creditors (including trade creditors) of such Subsidiary and holders of such Subsidiary’s preferred stock and any Guarantees by such Subsidiary of Indebtedness of Amkor. If Amkor were a creditor of such Subsidiary or a holder of its preferred stock, we would be entitled to participate in the distribution of the proceeds of such Subsidiary’s assets. Our claims would, however, remain subordinate to any Indebtedness or preferred stock of such Subsidiary that is senior in right of payment to the Indebtedness or preferred stock held by us. In the event of the liquidation, bankruptcy, reorganization, insolvency, receivership or similar proceeding or any assignment for the benefit of our creditors or a marshaling of our assets or liabilities, holders of the Notes may receive ratably less than other such creditors or interest holders.

31

 

      As of the date of the Indenture, all our Subsidiaries were “Restricted Subsidiaries.” However, under the circumstances described below under the caption “— Certain Covenants — Designation of Restricted and Unrestricted Subsidiaries,” we will be permitted to designate certain of our Subsidiaries as “Unrestricted Subsidiaries.” Unrestricted Subsidiaries will not be subject to many of the restrictive covenants in the Indenture.

Principal, Maturity and Interest

      The Notes will mature on March 15, 2011.

      Interest on the Notes will accrue at the rate of 7 1/8% per annum and will be payable semiannually in arrears on March 15 and September 15, commencing on September 15, 2004. Amkor will make each interest payment to the holders of record of the Notes on the immediately preceding March 1 and September 1.

      Interest on the Notes will accrue from the date of original issuance or, if interest has already been paid, from the date it was most recently paid. Interest will be computed on the basis of a 360-day year comprised of twelve 30-day months.

      The interest rate on the Notes is subject to increase if Amkor does not file a registration statement relating to the exchange offer on a timely basis, if the registration statement is not declared effective on a timely basis or if certain other conditions are not satisfied, all as further described under the caption “— Registration Rights; Liquidated Damages.”

      All references to interest on the Notes include any such Liquidated Damages that may be payable. Amkor will issue Notes in denominations of $1,000 and integral multiples of $1,000.

Optional Redemption

      Except as set forth below, the Notes will not be redeemable at the option of Amkor prior to March 15, 2011. The Notes are subject to redemption upon not less than 30 nor more than 60 days’ notice by mail, as a whole or in part, at the election of Amkor, at a price equal to the sum of (i) 100% of the principal amount thereof plus accrued interest to the redemption date plus (ii) the Make-Whole Amount, if any.

      At any time, and from time to time, prior to March 15, 2007, Amkor may redeem up to a maximum of 35% of the aggregate principal amount of the Notes with the proceeds of one or more Equity Offerings at a redemption price (expressed as a percentage of the principal amount) equal to 107.125% of the principal amount thereof, plus accrued and unpaid interest to the redemption date (subject to the rights of holders of record on the relevant record date to receive interest due on the relevant interest payment date); provided, however, that after giving effect to any such redemption at least 65% of the original aggregate principal amount of the Notes (excluding Notes held by Amkor and its Subsidiaries) remains outstanding. The redemption must occur within 45 days of the date of the closing of such Equity Offering.

Repurchase at the Option of Holders

     Offer to Repurchase Upon Change of Control

      If a Change of Control occurs, each holder of the Notes will have the right to require Amkor to repurchase all or any part (equal to $1,000 or an integral multiple thereof) of that holder’s Notes pursuant to an offer made by Amkor (the “Change of Control Offer”). In the Change of Control Offer, Amkor will offer to make a payment (the “Change of Control Payment” in cash equal to 101% of the aggregate principal amount of Notes repurchased, plus accrued and unpaid interest thereon and Liquidated Damages, if any, to the date of purchase. Within 30 days following any Change of Control, Amkor will mail a notice to each holder of the Notes describing the transaction or transactions that constitute the Change of Control and offering to repurchase Notes on the date specified in such notice (the “Change of Control Payment Date”), pursuant to the procedures required by the Indenture and described in such notice. Amkor will comply with the requirements of Rule 14e-1 under the Exchange Act and any other securities laws and regulations

32

 
thereunder to the extent such laws and regulations are applicable in connection with the repurchase of the Notes as a result of a Change of Control.

      On the Change of Control Payment Date, Amkor will, to the extent lawful:
 	 	
 	      (1) accept for payment all Notes or portions thereof properly tendered pursuant to the Change of Control Offer;	
 	 	
 	      (2) deposit with the Paying Agent an amount equal to the Change of Control Payment in respect of all Notes or portions thereof so tendered; and	
 	 	
 	      (3) deliver or cause to be delivered to the Trustee the Notes so accepted together with an Officers’ Certificate stating the aggregate principal amount of Notes or portions thereof being purchased by Amkor.	
      The Paying Agent will promptly mail to each holder of the Notes so tendered the Change of Control Payment for such Notes, and the Trustee will promptly authenticate and mail (or cause to be transferred by book entry) to each holder a new Note equal in principal amount to any unpurchased portion of the Notes surrendered, if any; provided that each such new Note will be in a principal amount of $1,000 or an integral multiple thereof.

      Amkor will publicly announce the results of the Change of Control Offer on or as soon as practicable after the Change of Control Payment Date.

      The provisions described above that require Amkor to make a Change of Control Offer following a Change of Control will be applicable regardless of whether or not any other provisions of the Indenture are applicable. Except as described above with respect to a Change of Control, the Indenture does not contain provisions that permit the holders of the Notes to require that Amkor repurchase or redeem the Notes in the event of a takeover, recapitalization or similar transaction.

      Amkor will not be required to make a Change of Control Offer upon a Change of Control if a third party makes the Change of Control Offer in the manner, at the times and otherwise in compliance with the requirements set forth in the Indenture applicable to a Change of Control Offer made by Amkor and purchases all Notes validly tendered and not withdrawn under such Change of Control Offer.

      The definition of Change of Control includes a phrase relating to the sale, lease, transfer, conveyance or other disposition of “all or substantially all” of the assets of Amkor and its Subsidiaries taken as a whole. Although there is a limited body of case law interpreting the phrase “substantially all,” there is no precise established definition of the phrase under applicable law. Accordingly, the ability of a holder of the Notes to require Amkor to repurchase such Notes as a result of a sale, lease, transfer, conveyance or other disposition of less than all the assets of Amkor and its Subsidiaries taken as a whole to another Person or group may be uncertain.

     Offer to Repurchase by Application of Excess Proceeds of Asset Sales

      Amkor will not, and will not permit any of its Restricted Subsidiaries to, consummate an Asset Sale unless:
 	 	
 	      (1) Amkor (or the Restricted Subsidiary, as the case may be) receives consideration at the time of such Asset Sale at least equal to the fair market value of the assets or Equity Interests issued or sold or otherwise disposed of;	
 	 	
 	      (2) such fair market value is determined by the Board of Directors; and	
 	 	
 	      (3) at least 75% of the consideration therefor received by Amkor or such Restricted Subsidiary is in the form of cash or other Qualified Proceeds.	
33

 

      Within 365 days after the receipt of any Net Proceeds from an Asset Sale, Amkor may apply such Net Proceeds at its option:
 	 	
 	      (1) to repay Permitted Bank Debt, and if such Permitted Bank Debt is revolving debt, to effect a corresponding commitment reduction thereunder;	
 	 	
 	      (2) to acquire all or substantially all the assets of, or a majority of the Voting Stock of, another Permitted Business;	
 	 	
 	      (3) to make a capital expenditure; or	
 	 	
 	      (4) to acquire any other long-term assets that are used or useful in a Permitted Business.	
      Pending the final application of any such Net Proceeds, Amkor may temporarily reduce revolving credit borrowings or otherwise invest such Net Proceeds in any manner that is not prohibited by the Indenture.

      Any Net Proceeds from any Asset Sale that are not applied or invested as provided in the preceding paragraph within 365 days of such Asset Sale will constitute “Excess Proceeds.” When the aggregate amount of Excess Proceeds exceeds $10.0 million, Amkor will make an offer (the “Asset Sale Offer”) to all holders of the Notes and all holders of other Indebtedness that is pari passu with the Notes containing provisions similar to those set forth in the Indenture with respect to offers to purchase or redeem with the proceeds of sales of assets to purchase the maximum principal amount of Notes and such other pari passu Indebtedness that may be purchased out of the Excess Proceeds. The offer price in any Asset Sale Offer will be equal to 100.0% of principal amount plus accrued and unpaid interest, if any, to the date of purchase, and will be payable in cash. If any Excess Proceeds remain after consummation of an Asset Sale Offer, Amkor may use such Excess Proceeds for any purpose not otherwise prohibited by the Indenture. If the aggregate principal amount of Notes and such other pari passu Indebtedness tendered into such Asset Sale Offer exceeds the amount of Excess Proceeds, the Trustee shall select the Notes and such other pari passu Indebtedness to be purchased on a pro rata basis. Upon completion of each Asset Sale Offer, the amount of Excess Proceeds shall be reset at zero.

Certain Covenants

     Restricted Payments

      Amkor will not, and will not permit any of its Restricted Subsidiaries to, directly or indirectly:
 	 	
 	      (1) declare or pay any dividend or make any other payment or distribution on account of Amkor’s or any of its Restricted Subsidiaries’ Equity Interests (including, without limitation, any payment in connection with any merger or consolidation involving Amkor or any of its Restricted Subsidiaries) or to the direct or indirect holders of Amkor’s or any of its Restricted Subsidiaries’ Equity Interests in their capacity as such (other than dividends or distributions payable in Equity Interests (other than Disqualified Stock) of Amkor or to Amkor or a Restricted Subsidiary of Amkor);	
 	 	
 	      (2) purchase, redeem or otherwise acquire or retire for value (including, without limitation, in connection with any merger or consolidation involving Amkor) any Equity Interests of Amkor or any direct or indirect parent of Amkor or any Restricted Subsidiary of Amkor (other than any such Equity Interests owned by Amkor or any Restricted Subsidiary of Amkor);	
 	 	
 	      (3) make any payment on or with respect to, or purchase, redeem, defease or otherwise acquire or retire for value any Indebtedness that is subordinated to the Notes, except a payment of interest or principal at the Stated Maturity thereof; or	
 	 	
 	      (4) make any Restricted Investment (all such payments and other actions set forth in clauses (1) through (4) above being collectively referred to as “Restricted Payments”),	
unless, at the time of and after giving effect to such Restricted Payment:
 	 	
 	      (1) no Default or Event of Default shall have occurred and be continuing or would occur as a consequence thereof;	
34

 
 	 	
 	      (2) Amkor would, at the time of such Restricted Payment and after giving pro forma effect thereto as if such Restricted Payment had been made at the beginning of the applicable four-quarter period, have been permitted to incur at least $1.00 of additional Indebtedness pursuant to the Consolidated Interest Expense Coverage Ratio test set forth in the first paragraph of the covenant described below under the caption “— Certain Covenants — Incurrence of Indebtedness and Issuance of Preferred Stock”; and	
 	 	
 	      (3) such Restricted Payment, together with the aggregate amount of all other Restricted Payments made by Amkor and its Restricted Subsidiaries after the Issue Date (excluding Restricted Payments permitted by clauses (2), (3), (4), (7) and (9) of the next succeeding paragraph), is less than the sum, without duplication, of:	

 	      (a) 50% of the Consolidated Net Income of Amkor for the period (taken as one accounting period) from the beginning of the fiscal quarter commencing on April 1, 2003 to the end of Amkor’s most recently ended fiscal quarter for which internal financial statements are available at the time of such Restricted Payment (or, if such Consolidated Net Income for such period is a deficit, less 100% of such deficit), plus	
 	 	
 	      (b) 100% of the aggregate net cash proceeds received by Amkor since the Issue Date as a contribution to its common equity capital or from the issue or sale of Equity Interests of Amkor (other than Disqualified Stock) (other than Equity Interests (or Disqualified Stock or debt securities) sold to a Subsidiary of Amkor), plus	
 	 	
 	      (c) to the extent that any Restricted Investment that was made after the Issue Date is sold for cash or otherwise liquidated or repaid for cash, the lesser of (i) the cash return of capital with respect to such Restricted Investment (less the cost of disposition, if any) and (ii) the initial amount of such Restricted Investment, plus	
 	 	
 	      (d) the amount by which (i) Indebtedness (other than Disqualified Stock) of Amkor or any Restricted Subsidiary issued after the Issue Date is reduced on Amkor’s consolidated balance sheet (if prepared in accordance with GAAP as of the date of determination) and (ii) Disqualified Stock of Amkor issued after the Issue Date (held by any Person other than any Restricted Subsidiary) is reduced (measured with reference to its redemption or repurchase price), in each case, as a result of the conversion or exchange of any such Indebtedness or Disqualified Stock into Equity Interests (other than Disqualified Stock) of Amkor, less, in each case, any cash distributed by Amkor upon such conversion or exchange, plus	
 	 	
 	      (e) to the extent that any Investment in any Unrestricted Subsidiary that was made after the Issue Date is sold for cash or otherwise liquidated, repaid for cash or such Unrestricted Subsidiary is converted into a Restricted Subsidiary, the lesser of (i) an amount equal to the sum of (A) the net reduction in Investments in Unrestricted Subsidiaries resulting from dividends, repayments of loans or advances or other transfers of assets, in each case to Amkor or any Restricted Subsidiary from Unrestricted Subsidiaries, and (B) the fair market value of the net assets of an Unrestricted Subsidiary at the time such Unrestricted Subsidiary is designated a Restricted Subsidiary, and (ii) the remaining amount of the Investment in such Unrestricted Subsidiary which has not been repaid or converted into cash or assets.	
      The preceding provisions will not prohibit:
 	 	
 	      (1) the payment of any dividend within 60 days after the date of declaration thereof, if at the date of declaration no Default has occurred and is continuing or would be caused thereby and such payment would have complied with the provisions of the Indenture;	
 	 	
 	      (2) the making of any payment on or with respect to, or in connection with, the redemption, repurchase, retirement, defeasance or other acquisition of, any Indebtedness of Amkor or any Restricted Subsidiary that is subordinated to the Notes or of any Equity Interests of Amkor or any Restricted Subsidiary in exchange for, or out of the net cash proceeds of the substantially concurrent sale (other than to a Subsidiary of Amkor) of, Equity Interests (other than Disqualified Stock) of Amkor or any	
35

 
 	 	
 	subordinated Indebtedness of Amkor; provided that the amount of any such net cash proceeds that are utilized for any such redemption, repurchase, retirement, defeasance or other acquisition shall be excluded from clause (3)(b) of the preceding paragraph;	
 	 	
 	      (3) the making of any payment on or with respect to, or in connection with, the defeasance, redemption, repurchase or other acquisition of Indebtedness of Amkor or any Restricted Subsidiary that is subordinated to the Notes with the net cash proceeds from the incurrence of Permitted Refinancing Indebtedness;	
 	 	
 	      (4) the payment of any dividend by a Restricted Subsidiary of Amkor to the holders of its common Capital Stock on a pro rata basis;	
 	 	
 	      (5) so long as no Default has occurred and is continuing or would be caused thereby, the repurchase, redemption or other acquisition or retirement for value of any Equity Interests of Amkor or any Restricted Subsidiary of Amkor held by any employee of Amkor or any Restricted Subsidiary pursuant to any employee equity subscription agreement, stock ownership plan or stock option agreement in effect from time to time; provided that the aggregate price paid for all such repurchased, redeemed, acquired or retired Equity Interests shall not exceed $2.0 million in any twelve-month period and $10.0 million in the aggregate;	
 	 	
 	      (6) the making of any payment on or with respect to, or repurchase, redemption, defeasance or other acquisition or retirement for value of the 5.75% subordinated convertible notes due 2006 or the 5.00% subordinated convertible notes due 2007 in connection with (i) so long as no Event of Default has occurred and is continuing or would be caused thereby, an optional redemption of such convertible notes on or after the dates such notes become redeemable, or (ii) the honoring by Amkor of any conversion request into Capital Stock (other than Disqualified Stock) by a holder of either such convertible notes or any future convertible notes of Amkor (including the payment by Amkor of any cash in lieu of fractional shares) in accordance with their terms;	
 	 	
 	      (7) that portion of Investments the payment for which consists exclusively of Equity Interests (other than Disqualified Stock) of Amkor;	
 	 	
 	      (8) so long as no Default has occurred and is continuing or would be caused thereby, other Restricted Payments in an aggregate amount not to exceed $75.0 million;	
 	 	
 	      (9) the repurchase of Equity Interests of Amkor that may be deemed to occur upon the exercise of stock options if such Equity Interests represent a portion of the exercise price thereof;	
 	 	
 	      (10) any payments to one or more stockholders of Amkor in connection with settling stockholder obligations for income taxes in respect of tax periods ending prior to the conversion of Amkor from “S” corporation status to “C” corporation status;	
 	 	
 	      (11) in the case of an Asset Sale, any Asset Sale Offer after Amkor has complied with its obligations to the holders of the Notes under the “Asset Sale” covenant contained in the Indenture; and	
 	 	
 	      (12) in the case of a Change of Control, any Change of Control Offer to repurchase the senior subordinated notes after Amkor has complied with its obligations to the holders of the Notes under the “Change of Control” covenant contained in the Indenture.	
      The amount of all Restricted Payments (other than cash) shall be the fair market value on the date of the Restricted Payment of the assets or securities proposed to be transferred or issued by Amkor or such Restricted Subsidiary, as the case may be, pursuant to the Restricted Payment. The fair market value of any assets or securities that are required to be valued by this covenant with a fair market value in excess of $1.0 million but less than $5.0 million shall be evidenced by an Officer’s Certificate which shall be delivered to the Trustee. The fair market value of any assets or securities that are required to be valued by this covenant with a fair market value in excess of $5.0 million shall be determined by the Board of Directors whose resolution with respect thereto shall be delivered to the Trustee.

     Incurrence of Indebtedness and Issuance of Preferred Stock

      Amkor will not, and will not permit any of its Restricted Subsidiaries to, directly or indirectly, create, incur, issue, assume, guarantee or otherwise become directly or indirectly liable, contingently or otherwise, with respect to (collectively, “incur”) any Indebtedness (including Acquired Debt), and Amkor will not issue any Disqualified Stock and will not permit any of its Restricted Subsidiaries to issue any shares of preferred stock; provided, however, that Amkor and any Restricted Subsidiary that is a Guarantor may incur Indebtedness (including Acquired Debt), and Amkor may issue Disqualified Stock, and any Restricted Subsidiary that is a Guarantor may issue preferred stock, if the Consolidated Interest Expense Coverage Ratio for Amkor’s most recently ended four full fiscal quarters for which internal financial statements are available immediately preceding the date on which such additional Indebtedness is incurred or such Disqualified Stock or preferred stock is issued would have been at least 2.0 to 1, determined on a pro forma basis (including a pro forma application of the net proceeds therefrom), as if the additional Indebtedness had been incurred, or the Disqualified Stock or preferred stock had been issued, as the case may be, at the beginning of such four-quarter period.

      The first paragraph of this covenant will not prohibit the incurrence of any of the following items of Indebtedness (collectively, “Permitted Debt”):
 	 	
 	      (1) the incurrence by Amkor and any Restricted Subsidiary of any Permitted Bank Debt; provided that the aggregate principal amount of all Permitted Bank Debt at any one time outstanding shall not exceed $100.0 million plus 85% of the consolidated accounts receivable of Amkor plus 50% of the consolidated inventory of Amkor;	
 	 	
 	      (2) the incurrence by Amkor and its Subsidiaries of Existing Indebtedness;	
 	 	
 	      (3) the incurrence by Amkor and any Guarantor of Indebtedness represented by the Notes, and any Subsidiary Guarantees;	
 	 	
 	      (4) the incurrence by Amkor or any of its Restricted Subsidiaries of (a) Indebtedness incurred for the purpose of financing all or any part of the purchase price or cost of construction or improvement of property, plant or equipment used in the business of Amkor or such Restricted Subsidiary and (b) Capital Lease Obligations, in an aggregate amount at any time outstanding, including all Permitted Refinancing Indebtedness incurred to refund, refinance or replace any Indebtedness incurred pursuant to this clause (4), not to exceed the greater of $75.0 million and 10% of Amkor’s Consolidated Net Assets;	
 	 	
 	      (5) the incurrence by Amkor or any of its Restricted Subsidiaries of Permitted Refinancing Indebtedness in exchange for, or the net proceeds of which are used to refund, refinance or replace Indebtedness (other than intercompany Indebtedness) that was permitted by the Indenture to be incurred under the first paragraph of this covenant or clause (2), (3), (5), (13) or (14) of this paragraph;	
 	 	
 	      (6) the incurrence by Amkor or any of its Restricted Subsidiaries of intercompany Indebtedness between or among Amkor and any of its Restricted Subsidiaries; provided, however, that:	

 	      (a) if Amkor or any Guarantor is the obligor on such Indebtedness and such Indebtedness is in favor of a Restricted Subsidiary other than a Wholly Owned Restricted Subsidiary, such Indebtedness must be expressly subordinated to the prior payment in full in cash of all Obligations with respect to the Notes, in the case of Amkor, or the Subsidiary Guarantee, in the case of a Guarantor; and	
 	 	
 	      (b) (i) any subsequent issuance or transfer of Equity Interests that results in any such Indebtedness being held by a Person other than Amkor or a Wholly Owned Restricted Subsidiary thereof and (ii) any sale or other transfer of any such Indebtedness to a Person that is not either Amkor or a Wholly Owned Restricted Subsidiary thereof shall be deemed, in each case, to constitute an incurrence of such Indebtedness by Amkor or such Restricted Subsidiary, as the case may be, that was not permitted by this clause (6);	
37

 
 	 	
 	      (7) the incurrence by Amkor or any of its Restricted Subsidiaries of Hedging Obligations that are incurred for the purpose of fixing or hedging interest rate, commodity or currency risk in the ordinary course of business for bona fide hedging purposes; provided that the notional principal amount of any such Hedging Obligation with respect to interest rates does not exceed the amount of Indebtedness or other liability to which such Hedging Obligation relates;	
 	 	
 	      (8) the Guarantee by Amkor or any of the Guarantors of Indebtedness of Amkor or a Restricted Subsidiary of Amkor that was permitted to be incurred by another provision of this covenant;	
 	 	
 	      (9) the incurrence by Amkor’s Unrestricted Subsidiaries of Non-Recourse Debt; provided, however, that if any such Indebtedness ceases to be Non-Recourse Debt of an Unrestricted Subsidiary, such event shall be deemed to constitute an incurrence of Indebtedness by a Restricted Subsidiary of Amkor that was not permitted by this clause (9);	
 	 	
 	      (10) the incurrence of Indebtedness solely in respect of performance, surety and similar bonds or completion or performance Guarantees, to the extent that such incurrence does not result in the incurrence of any obligation for the payment of borrowed money to others;	
 	 	
 	      (11) the incurrence of Indebtedness arising from the agreements of Amkor or a Restricted Subsidiary of Amkor providing for indemnification, adjustment of purchase price or similar obligations, in each case, incurred or assumed in connection with the disposition of any business, assets or a Subsidiary; provided, however, that:	

 	      (a) such Indebtedness is not reflected as a liability on the balance sheet of Amkor or any Restricted Subsidiary of Amkor; and	
 	 	
 	      (b) the maximum assumable liability in respect of all such Indebtedness shall at no time exceed the gross proceeds, including non-cash proceeds (the fair market value of such non-cash proceeds being measured at the time received and without giving effect to any subsequent changes in value), actually received by Amkor and its Restricted Subsidiaries in connection with such disposition;	

 	      (12) the accrual of interest, accretion or amortization of original issue discount, the payment of interest on any Indebtedness in the form of additional Indebtedness with the same terms, and the payment of dividends on Disqualified Stock in the form of additional shares of the same class of Disqualified Stock; provided, in each such case, that the amount thereof is included in Consolidated Interest Expense of Amkor as accrued;	
 	 	
 	      (13) the incurrence of Indebtedness by Foreign Subsidiaries in an amount not to exceed 10% of the Total Tangible Assets of the Foreign Subsidiaries, taken as a whole; and	
 	 	
 	      (14) the incurrence by Amkor or any of its Restricted Subsidiaries of additional Indebtedness in an aggregate principal amount (or accreted value, as applicable) at any time outstanding, including all Permitted Refinancing Indebtedness incurred to refund, refinance or replace any Indebtedness incurred pursuant to this clause (14), not to exceed $50.0 million.	
      Indebtedness or preferred stock of any Person that is outstanding at the time such Person becomes a Restricted Subsidiary of Amkor (including upon designation of any Subsidiary or other Person as a Restricted Subsidiary) or is merged with or into or consolidated with Amkor or a Restricted Subsidiary of Amkor shall be deemed to have been incurred at the time such Person becomes such a Restricted Subsidiary of Amkor or is merged with or into or consolidated with Amkor or a Restricted Subsidiary of Amkor, as applicable.

      Amkor will not incur any Indebtedness (including Permitted Debt) that is contractually subordinated in right of payment to any other Indebtedness of Amkor unless such Indebtedness is also contractually subordinated in right of payment to the Notes on substantially identical terms; provided, however, that no Indebtedness of Amkor shall be deemed to be contractually subordinated in right of payment to any other Indebtedness of Amkor solely by virtue of any Liens, Guarantees, maturity of payments or structural seniority.

38

 

      For purposes of determining compliance with this “Incurrence of Indebtedness and Issuance of Preferred Stock” covenant, in the event that an item of proposed Indebtedness meets the criteria of more than one of the categories of Permitted Debt described in clauses (1) through (14) above, or is entitled to be incurred pursuant to the first paragraph of this covenant, Amkor will, at its sole discretion, classify or reclassify such item of Indebtedness (or any part thereof) in any manner that complies with this covenant, and such item of Indebtedness shall be treated as having been incurred pursuant to only one of such clauses or pursuant to the first paragraph of this covenant.

      For purposes of determining any particular amount of Indebtedness under this covenant, Guarantees, Liens or obligations in support of letters of credit supporting Indebtedness shall not be included to the extent such letters of credit are included in the amount of such Indebtedness.

      Any increase in the amount of any Indebtedness solely by reason of currency fluctuations shall not be considered an incurrence of Indebtedness for purposes of this covenant.

     Liens

      Amkor will not, and will not permit any of its Restricted Subsidiaries to, directly or indirectly, create, incur, assume or suffer to exist any Lien of any kind securing Indebtedness on any asset now owned or hereafter acquired, except Permitted Liens, unless the Notes are equally and ratably secured with the obligations so secured for as long as such Indebtedness will be so secured.

 	Dividend and Other Payment Restrictions Affecting Subsidiaries	
      Amkor will not, and will not permit any of its Restricted Subsidiaries to, directly or indirectly, create or permit to exist or become effective any encumbrance or restriction on the ability of any Restricted Subsidiary to:
 	 	
 	      (1) pay dividends or make any other distributions on its Capital Stock to Amkor or any of Amkor’s Restricted Subsidiaries, or with respect to any other interest or participation in, or measured by, its profits, or pay any indebtedness owed to Amkor or any of Amkor’s Restricted Subsidiaries;	
 	 	
 	      (2) make loans or advances to Amkor or any of Amkor’s Restricted Subsidiaries; or	
 	 	
 	      (3) transfer any of its properties or assets to Amkor or any of Amkor’s Restricted Subsidiaries.	

 	However, the preceding restrictions will not apply to encumbrances or restrictions existing under or by reason of:	

 	      (1) Existing Indebtedness as in effect on the date of the Indenture and any amendments, modifications, restatements, renewals, increases, supplements, refundings, replacements or refinancings thereof;  provided  that such amendments, modifications, restatements, renewals, increases, supplements, refundings, replacements or refinancings are no more restrictive, taken as a whole, with respect to such dividend and other payment restrictions than those contained in such Existing Indebtedness, as in effect on the date of the Indenture;	
 	 	
 	      (2) the Indenture and the Notes;	
 	 	
 	      (3) applicable law;	
 	 	
 	      (4) any instrument governing Indebtedness or Capital Stock of a Person acquired by Amkor or any of its Restricted Subsidiaries as in effect at the time of such acquisition (except to the extent such Indebtedness was incurred in connection with or in contemplation of such acquisition), which encumbrance or restriction is not applicable to any Person, or the properties or assets of any Person, other than the Person, or the property or assets of the Person, so acquired;  provided  that, in the case of Indebtedness, such Indebtedness was permitted by the terms of the Indenture to be incurred;	
 	 	
 	      (5) customary nonassignment provisions in leases, licenses or other contracts entered into in the ordinary course of business and consistent with past practices;	
39

 
 	 	
 	      (6) purchase money obligations or Capital Lease Obligations for property acquired in the ordinary course of business that impose restrictions on the property so acquired of the nature described in clause (3) of the first paragraph of this section;	
 	 	
 	      (7) any agreement for the sale or other disposition of a Restricted Subsidiary that restricts dividends, distributions, loans, advances or transfers by such Restricted Subsidiary pending its sale or other disposition;	
 	 	
 	      (8) Permitted Refinancing Indebtedness; provided that the restrictions contained in the agreements governing such Permitted Refinancing Indebtedness are no more restrictive, taken as a whole, than those contained in the agreements governing the Indebtedness being refinanced;	
 	 	
 	      (9) agreements entered into with respect to Liens securing Indebtedness otherwise permitted to be incurred pursuant to the provisions of the covenant described above under the caption “— Certain Covenants — Liens” that limit the right of Amkor or any of its Restricted Subsidiaries to dispose of the assets subject to such Lien;	
 	 	
 	      (10) provisions with respect to the disposition or distribution of assets or property in joint venture agreements and other similar agreements entered into in the ordinary course of business;	
 	 	
 	      (11) restrictions on cash or other deposits or net worth imposed by customers under contracts entered into in the ordinary course of business;	
 	 	
 	      (12) any Receivables Program; and	
 	 	
 	      (13) any restriction imposed pursuant to contracts for the sale of assets with respect to the transfer of the assets to be sold pursuant to such contract.	

 	Merger, Consolidation or Sale of Assets	
      Amkor may not, directly or indirectly consolidate or merge with or into another Person (whether or not Amkor is the surviving corporation) or sell, assign, transfer, convey or otherwise dispose of all or substantially all of its properties or assets, in one or more related transactions, to another Person, unless:
 	 	
 	      (1) either (a) Amkor is the surviving corporation or (b) the Person formed by or surviving any such consolidation or merger (if other than Amkor) or to which such sale, assignment, transfer, conveyance or other disposition shall have been made is a corporation organized or existing under the laws of the United States, any state thereof or the District of Columbia;	
 	 	
 	      (2) the Person formed by or surviving any such consolidation or merger (if other than Amkor) or the Person to which such sale, assignment, transfer, conveyance or other disposition shall have been made assumes all the obligations of Amkor under the Notes, the Indenture and the Registration Rights Agreement pursuant to agreements reasonably satisfactory to the Trustee;	
 	 	
 	      (3) immediately after such transaction no Default or Event of Default exists;	
 	 	
 	      (4) except in the case of the amalgamation, consolidation or merger of Amkor (a) with or into a Wholly Owned Restricted Subsidiary or (b) with or into any Person solely for the purpose of effecting a change in the state of incorporation of Amkor, Amkor or the Person formed by or surviving any such consolidation or merger (if other than Amkor) will, on the date of such transaction after giving pro forma effect thereto and any related financing transactions as if the same had occurred at the beginning of the applicable four-quarter period, be permitted to incur at least $1.00 of additional Indebtedness pursuant to the Consolidated Interest Expense Coverage Ratio test set forth in the first paragraph of the covenant described above under the caption “— Certain Covenants — Incurrence of Indebtedness and Issuance of Preferred Stock”; and	
 	 	
 	      (5) Amkor shall have delivered to the Trustee an Officer’s Certificate stating that such consolidation, merger, sale, assignment, transfer, conveyance or other disposition complies with the Indenture.	
40

 

      In addition, Amkor may not, directly or indirectly, lease all or substantially all of its properties or assets, in one or more related transactions, to any other Person. This “Merger, Consolidation or Sale of Assets” covenant will not apply to a sale, assignment, transfer, conveyance or other disposition of assets by Amkor to any of its Wholly Owned Restricted Subsidiaries.

 	Transactions with Affiliates	
      Amkor will not, and will not permit any of its Restricted Subsidiaries to, make any payment to, or sell, lease, transfer or otherwise dispose of any of its properties or assets to, or purchase any property or assets from, or enter into or make or amend any transaction, contract, agreement, understanding, loan, advance or Guarantee with, or for the benefit of, any Affiliate (each, an “Affiliate Transaction”), unless:
 	 	
 	      (1) such Affiliate Transaction (when viewed together with related Affiliate Transactions, if any) is on terms that are no less favorable to Amkor or the relevant Restricted Subsidiary than those that would have been obtained in a comparable transaction by Amkor or such Restricted Subsidiary with an unrelated Person; and	
 	 	
 	      (2) Amkor delivers to the Trustee:	

 	      (a) with respect to any Affiliate Transaction or series of related Affiliate Transactions involving aggregate consideration in excess of $10.0 million, a resolution of the Board of Directors set forth in an Officer’s Certificate certifying that such Affiliate Transaction complies with this covenant and that such Affiliate Transaction has been approved by a majority of the disinterested members of the Board of Directors (of which there must be at least one); and	
 	 	
 	      (b) with respect to any Affiliate Transaction or series of related Affiliate Transactions involving aggregate consideration in excess of $25.0 million, an opinion as to the fairness to the holders of such Affiliate Transaction from a financial point of view issued by an accounting, appraisal or investment banking firm of national standing;	
provided that (i) Amkor and its Restricted Subsidiaries may enter into Affiliate Transactions pursuant to the Supply Agreement, the Foundry Agreement, the Asset Purchase Agreement, the Transition Services Agreement and the Intellectual Property Rights Licensing Agreement, and may amend, modify and supplement such agreements from time to time, so long as Amkor shall have determined that any such amendment, modification or supplement will not have a material adverse economic effect on Amkor and its Subsidiaries, taken as a whole, and (ii) Amkor and its Restricted Subsidiaries may only enter into transactions pursuant to the Supply Agreement, the Foundry Agreement, the Asset Purchase Agreement, the Transition Services Agreement and the Intellectual Property Rights Licensing Agreement, and amend, modify and supplement such agreements from time to time, in circumstances in which clause (i) is not applicable, if a majority of the disinterested members of the Board of Directors (of which there must be at least one) shall have approved such transaction, amendment, modification or supplement;  provided ,  further , that in the case of both clauses (i) and (ii), Amkor shall deliver to the Trustee within 30 days of such transaction, amendment, modification or supplement an Officer’s Certificate (A) describing the transaction, amendment, modification or supplement approved, (B) in the case of transactions, amendments, modifications and supplements to which clause (i) is applicable, setting forth the determination of Amkor required pursuant to clause (i), and (C) in the case of transactions, amendments, modifications and supplements to which clause (ii) is applicable, attaching a resolution of the Board of Directors certifying that such Affiliate Transaction complies with this covenant.

      The following items shall not be deemed Affiliate Transactions and, therefore, will not be subject to the provisions of the prior paragraphs:
 	 	
 	      (1) any employment agreement or arrangement entered into by Amkor or any of its Restricted Subsidiaries or any employee benefit plan available to employees of Amkor and its Subsidiaries generally, in each case in the ordinary course of business and consistent with the past practice of Amkor or such Restricted Subsidiary;	
41

 
 	 	
 	      (2) Affiliate Transactions between or among Amkor and/or its Restricted Subsidiaries;	
 	 	
 	      (3) payment of reasonable directors’ fees to Persons who are not otherwise Affiliates of Amkor and indemnity provided on behalf of officers, directors and employees of Amkor or any of its Restricted Subsidiaries as determined in good faith by the Board of Directors of Amkor;	
 	 	
 	      (4) Any Affiliate Transactions pursuant to which Amkor makes short-term advances or otherwise makes short-term loans to ASI, which advances or loans are to be repaid by ASI (i) within three months from the date of such advance or loan and (ii) by offsets by Amkor of amounts payable by Amkor to ASI pursuant to the Supply Agreement, if a majority of the disinterested members of the Board of Directors (of which there must be at least one) shall have approved such transaction, amendment, modification or supplement;  provided  that the total amount of such advances and loans outstanding at any one time shall not exceed $50.0 million; and	
 	 	
 	      (5) Any Restricted Payments that are permitted as described above under the caption “— Certain Covenants — Restricted Payments.”	
      For purposes of this “Transactions With Affiliates” covenant, any transaction or series of related Affiliate Transactions between Amkor or any Restricted Subsidiary and an Affiliate that is approved by a majority of the disinterested members of the Board of Directors (of which there must be at least one to utilize this method of approval) and evidenced by a Board resolution or for which a fairness opinion has been issued shall be deemed to be on terms that are no less favorable to Amkor or the relevant Restricted Subsidiary than those that would have been obtained in a comparable transaction by Amkor or such Restricted Subsidiary with an unrelated Person and thus shall be permitted under this “Transactions With Affiliates” covenant.

 	Sale and Leaseback Transactions	
      Amkor will not, and will not permit any of its Subsidiaries to, enter into any sale and leaseback transaction; provided that Amkor or any Restricted Subsidiary may enter into a sale and leaseback transaction if:
 	 	
 	      (1) Amkor or such Restricted Subsidiary, as applicable, could have incurred Indebtedness in an amount equal to the Attributable Debt relating to such sale and leaseback transaction (if the lease is in the nature of an operating lease, otherwise the amount of Indebtedness) under the Consolidated Interest Expense Coverage Ratio test in the first paragraph of the covenant described above under the caption “— Certain Covenants — Incurrence of Indebtedness and Issuance of Preferred Stock”; and	
 	 	
 	      (2) the transfer of assets in that sale and leaseback transaction is permitted by, and Amkor applies the proceeds of such transaction in compliance with, the covenant described above under the caption “— Repurchase at the Option of Holders — Offer to Repurchase by Application of Excess Proceeds of Asset Sales.”	
      The foregoing restriction shall not apply to any sale and leaseback transaction if (i) the transaction is solely between Amkor and any Restricted Subsidiary or between Restricted Subsidiaries or (ii) the sale and leaseback transaction is consummated within 180 days after the purchase of the assets subject to such transaction.

 	No Amendment to Subordination Provisions	
      Without the consent of the holders of at least a majority in aggregate principal amount of the Notes then outstanding, Amkor will not amend, modify or alter the indenture governing the 10.50% senior subordinated notes due 2009 in any way to:
 	 	
 	      (1) increase the rate of or change the time for payment of interest on any 10.50% senior subordinated notes due 2009;	
 	 	
 	      (2) increase the principal of, advance the final maturity date of or shorten the Weighted Average Life to Maturity of any 10.50% senior subordinated notes due 2009;	
42

 
 	 	
 	      (3) alter the redemption provisions or the price or terms at which Amkor is required to offer to purchase any 10.50% senior subordinated notes due 2009; or	
 	 	
 	      (4) amend the subordinated provisions of Article 10 contained in the indenture governing the 10.50% senior subordinated notes due 2009.	

 	Subsidiary Guarantees	
      If Amkor or any of its Restricted Subsidiaries acquires, creates or capitalizes a Domestic Subsidiary after the date of the Indenture that is a Significant Subsidiary, then that newly acquired, created or capitalized Subsidiary must become a Guarantor and execute a supplemental indenture satisfactory to the Trustee and deliver an opinion of counsel to the Trustee within 10 business days of the date on which it was acquired or created. There are currently no subsidiary Guarantors.

 	Designation of Restricted and Unrestricted Subsidiaries	
      The Board of Directors may designate any Restricted Subsidiary to be an Unrestricted Subsidiary if that designation would not cause a Default. If a Restricted Subsidiary is designated as an Unrestricted Subsidiary, all outstanding Investments owned by Amkor and its Restricted Subsidiaries in the Subsidiary so designated will be deemed to be an Investment made as of the time of such designation and will reduce the amount available for Restricted Payments under the covenant described above under the caption “— Certain Covenants — Restricted Payments” or Permitted Investments, as applicable. All such outstanding Investments will be valued at their fair market value at the time of such designation. That designation will only be permitted if such Restricted Payment would be permitted at that time and if such Restricted Subsidiary otherwise meets the definition of an Unrestricted Subsidiary. The Board of Directors may redesignate any Unrestricted Subsidiary to be a Restricted Subsidiary if the redesignation would not cause a Default.

 	Limitation on Issuances and Sales of Equity Interests in Wholly Owned Restricted Subsidiaries	
      Amkor will not, and will not permit any of its Wholly Owned Restricted Subsidiaries to, transfer, convey, sell, lease or otherwise dispose of any Equity Interests in any Wholly Owned Restricted Subsidiary of Amkor to any Person (other than Amkor or a Wholly Owned Restricted Subsidiary of Amkor), unless:
 	 	
 	      (1) such transfer, conveyance, sale, lease or other disposition is of all the Equity Interests in such Wholly Owned Restricted Subsidiary or immediately following such transfer, conveyance, sale, lease or other disposition, the Wholly Owned Restricted Subsidiary is a Restricted Subsidiary; and	
 	 	
 	      (2) the cash Net Proceeds from such transfer, conveyance, sale, lease or other disposition are applied in accordance with the covenant described above under the caption “— Repurchase at the Option of Holders — Offer to Repurchase by Application of Excess Proceeds of Asset Sales.”	
      In addition, Amkor will not permit any Wholly Owned Restricted Subsidiary of Amkor to issue any of its Equity Interests (other than, if necessary, shares of its Capital Stock constituting directors’ qualifying shares) to any Person other than to Amkor or a Wholly Owned Restricted Subsidiary of Amkor unless immediately following such issuance the Wholly Owned Restricted Subsidiary is a Restricted Subsidiary.

Methods of Receiving Payments On The Notes

      If a holder has given wire transfer instructions to Amkor, Amkor will make all principal, premium and interest payments on those Notes in accordance with those instructions. All other payments on the Notes will be made at the office or agency of the Paying Agent and Registrar within the City and State of New York unless Amkor elects to make interest payments by check mailed to the holders at their addresses set forth in the register of holders.

43

 

Paying Agent and Registrar for the Notes

      The Trustee will initially act as Paying Agent and Registrar. Amkor may change the Paying Agent or Registrar without prior notice to the holders of the Notes, and Amkor or any of its Subsidiaries may act as Paying Agent or Registrar.

Transfer and Exchange

      A holder may transfer or exchange Notes in accordance with the Indenture. The Registrar and the Trustee may require a holder, among other things, to furnish appropriate endorsements and transfer documents and Amkor may require a holder to pay any taxes and fees required by law or permitted by the Indenture.

      The registered holder of a Note will be treated as its owner for all purposes.

Payments for Consent

      Amkor will not, and will not permit any of its Subsidiaries to, directly or indirectly, pay or cause to be paid any consideration to or for the benefit of any holder of the Notes for or as an inducement to any consent, waiver or amendment of any of the terms or provisions of the Indenture or the Notes unless such consideration is offered to be paid and is paid to all holders of the Notes that consent, waive or agree to amend in the time frame set forth in the solicitation documents relating to such consent, waiver or agreement.

Reports

      Whether or not required by the SEC, so long as any Notes are outstanding, Amkor shall file with the SEC (if permitted) all the reports and other information as it would be required to file with the SEC by Sections 13(a) and 15(d) under the Exchange Act, as if it were subject thereto. Amkor shall supply the Trustee and each holder of the Notes, or shall supply to the Trustee for forwarding to each holder of the Notes, without cost to any such holder, copies of such reports and other information (whether or not so filed).

Events of Default and Remedies

      With respect to the Notes, each of the following is an “Event of Default”:
 	 	
 	      (1) default for 30 days in the payment when due of interest on, or Liquidated Damages with respect to, the Notes;	
 	 	
 	      (2) default in payment when due of the principal of or premium, if any, on the Notes;	
 	 	
 	      (3) failure by Amkor or any of its Subsidiaries to make any payment required to be made under the provisions described above under the caption “— Repurchase at the Option of Holders — Offer to Repurchase Upon Change of Control” or “— Repurchase at the Option of Holders — Offer to Repurchase by Application of Excess Proceeds of Asset Sales;”	
 	 	
 	      (4) failure by Amkor or any of its Restricted Subsidiaries for 60 days after notice to comply with any covenant, representations, warranty or other agreements in the Indenture is provided to Amkor by the Trustee or the holders of at least 25% in principal amount of then outstanding Notes;	
 	 	
 	      (5) default under any mortgage, indenture or instrument under which there may be issued or by which there may be secured or evidenced any Indebtedness for money borrowed by Amkor or any of its Restricted Subsidiaries (or the payment of which is guaranteed by Amkor or any of its Restricted Subsidiaries) whether such Indebtedness or Guarantee now exists, or is created after the date of the Indenture, in an aggregate principal amount of $10.0 million or more, if that default:	

 	      (a) is caused by a failure to pay principal of such Indebtedness at the Stated Maturity thereof (a “Payment Default”); or	
 	 	
 	      (b) results in the acceleration of such Indebtedness prior to the Stated Maturity thereof;	
44

 
 	 	
 	      (6) failure by Amkor or any of its Significant Subsidiaries or any group of Subsidiaries that, taken together, would constitute a Significant Subsidiary, to pay final judgments aggregating in excess of $10.0 million (other than amounts covered by insurance), which judgments are not paid, discharged or stayed for a period of 60 days; and	
 	 	
 	      (7) certain events of bankruptcy or insolvency with respect to Amkor or any of its Significant Subsidiaries, or any group of Subsidiaries that, taken together, would constitute a Significant Subsidiary.	
      In the case of an Event of Default arising from certain events of bankruptcy or insolvency, with respect to Amkor, any Subsidiary that is a Significant Subsidiary or any group of Subsidiaries that, taken together, would constitute a Significant Subsidiary, all outstanding Notes will become due and payable immediately without further action or notice. If any other Event of Default occurs and is continuing, the Trustee or the holders of at least 25% in principal amount of the then outstanding Notes may declare all the Notes to be due and payable immediately.

      Holders of the Notes may not enforce their respective indentures or the Notes except as provided in the Indenture. Subject to certain limitations, holders of a majority in principal amount of the then outstanding Notes may direct the Trustee in its exercise of any trust or power. The Trustee may withhold from holders of the Notes notice of any continuing Default or Event of Default (except a Default or Event of Default relating to the payment of principal or interest) if it determines that withholding notice is in their interest.

      The holders of a majority in aggregate principal amount of the Notes then outstanding by notice to the Trustee may on behalf of the holders of all of the Notes waive any existing Default or Event of Default and its consequences under the Indenture except a continuing Default or Event of Default in the payment of interest on, or the principal of, the Notes.

      Amkor is required to deliver to the Trustee annually a statement regarding compliance with the Indenture. Upon becoming aware of any Default or Event of Default, Amkor is required to deliver to the Trustee a statement specifying such Default or Event of Default.

No Personal Liability of Directors, Officers, Employees and Stockholders

      No director, officer, employee, incorporator or stockholder of Amkor or any Guarantor, as such, shall have any liability for any obligations of Amkor or the Guarantors under the Notes, the Indenture, and the Subsidiary Guarantees or for any claim based on, in respect of, or by reason of, such obligations or their creation. Each holder of the Notes by accepting a Note waives and releases all such liability. The waiver and release are part of the consideration for issuance of the Notes. The waiver may not be effective to waive liabilities under the federal securities laws.

Legal Defeasance and Covenant Defeasance

      Amkor may, at its option and at any time, elect to have all of its obligations discharged with respect to the outstanding Notes and all obligations of the Guarantors discharged with respect to their Subsidiary Guarantees (“Legal Defeasance”), except for:
 	 	
 	      (1) the rights of holders of outstanding Notes to receive payments in respect of the principal of, premium, if any, and interest and Liquidated Damages on such Notes when such payments are due from the trust referred to below;	
 	 	
 	      (2) Amkor’s obligations with respect to the Notes concerning issuing temporary Notes, registration of Notes, mutilated, destroyed, lost or stolen Notes and the maintenance of an office or agency for payment and money for security payments held in trust;	
 	 	
 	      (3) the rights, powers, trusts, duties and immunities of the Trustee, and Amkor’s obligations in connection therewith; and	
 	 	
 	      (4) the Legal Defeasance provisions of the Indenture.	
45

 

      In addition, Amkor may, at its option and at any time, elect to have the Obligations of Amkor and the Guarantors released with respect to certain covenants that are described in the Indenture (“Covenant Defeasance”), and thereafter any omission to comply with those covenants shall not constitute a Default or Event of Default with respect to the Notes. In the event Covenant Defeasance occurs, certain events (other than nonpayment, bankruptcy, receivership, rehabilitation and insolvency events) described under the caption “— Events of Default and Remedies” will no longer constitute an Event of Default with respect to the Notes.

      In order to exercise either Legal Defeasance or Covenant Defeasance:
 	 	
 	      (1) Amkor must irrevocably deposit with the Trustee, in trust, for the benefit of the holders of the Notes, cash in United States dollars, noncallable government securities, or a combination thereof, in such amounts as will be sufficient, in the opinion of a nationally recognized firm of independent public accountants, to pay the principal of, premium and Liquidated Damages, if any, and interest and Liquidated Damages on the outstanding Notes at the Stated Maturity or on the applicable redemption date, as the case may be, and Amkor must specify whether the Notes are being defeased to maturity or to a particular redemption date;	
 	 	
 	      (2) in the case of Legal Defeasance, Amkor shall have delivered to the Trustee an opinion of counsel reasonably acceptable to the Trustee confirming that (a) Amkor has received from, or there has been published by, the Internal Revenue Service a ruling or (b) since the date of the Indenture, there has been a change in the applicable federal income tax law, in either case to the effect that, and based thereon such opinion of counsel shall confirm that, the holders of the outstanding Notes will not recognize income, gain or loss for federal income tax purposes as a result of such Legal Defeasance and will be subject to federal income tax on the same amounts, in the same manner and at the same times as would have been the case if such Legal Defeasance had not occurred;	
 	 	
 	      (3) in the case of Covenant Defeasance, Amkor shall have delivered to the Trustee an opinion of counsel reasonably acceptable to the Trustee confirming that the holders of the outstanding Notes will not recognize income, gain or loss for federal income tax purposes as a result of such Covenant Defeasance and will be subject to federal income tax on the same amounts, in the same manner and at the same times as would have been the case if such Covenant Defeasance had not occurred;	
 	 	
 	      (4) no Default or Event of Default shall have occurred and be continuing either (a) on the date of such deposit (other than a Default or Event of Default resulting from the borrowing of funds to be applied to such deposit) or (b) insofar as Events of Default from bankruptcy or insolvency events are concerned, at any time in the period ending on the 91st day after the date of deposit;	
 	 	
 	      (5) such Legal Defeasance or Covenant Defeasance will not result in a breach or violation of, or constitute a default under any material agreement or instrument (other than the Indenture) to which Amkor or any of its Restricted Subsidiaries are parties or by which Amkor or any of its Restricted Subsidiaries are bound;	
 	 	
 	      (6) Amkor must have delivered to the Trustee an opinion of counsel to the effect that after the 91st day following the deposit, the trust funds will not be subject to the effect of any applicable bankruptcy, insolvency, reorganization or similar laws affecting creditors’ rights generally;	
 	 	
 	      (7) Amkor must deliver to the Trustee an Officer’s Certificate stating that the deposit was not made by Amkor with the intent of preferring the holders of the Notes over the other creditors of Amkor with the intent of defeating, hindering, delaying or defrauding creditors of Amkor or others;	
 	 	
 	      (8) Amkor must deliver to the Trustee an Officer’s Certificate and an opinion of counsel, each stating that all conditions precedent relating to the Legal Defeasance or the Covenant Defeasance have been complied with; and	
 	 	
 	      (9) except as otherwise provided in the Indenture, each Guarantor shall have been released from any of its Obligations under its Guarantee of the Notes.	
46

 

Amendment, Supplement and Waiver

      Subject to the exceptions specified in the following paragraphs, the Indenture may be amended with the consent of the holders of a majority of the aggregate outstanding principal amount of the Notes and any Default or compliance with any provision of the Indenture may be waived with the consent of the holders of a majority of the aggregate outstanding principal amount of the Notes.

      Without the consent of each holder affected, an amendment or waiver may not (with respect to any Notes held by a nonconsenting holder):
 	 	
 	      (1) reduce the principal amount of Notes whose holders must consent to an amendment, supplement or waiver;	
 	 	
 	      (2) reduce the principal of or change the fixed maturity of any Note or alter the provisions with respect to the redemption of the Notes (other than provisions relating to the covenants described above under the caption “— Repurchase at the Option of Holders”);	
 	 	
 	      (3) reduce the rate of or change the time for payment of interest, including default interest, on any Note;	
 	 	
 	      (4) waive a Default or Event of Default in the payment of principal of or premium, if any, or interest on the Notes (except a rescission of acceleration of the Notes by the holders of at least a majority in aggregate principal amount of the Notes and a waiver of the Payment Default that resulted from such acceleration);	
 	 	
 	      (5) make any Note payable in money other than that stated in the Notes;	
 	 	
 	      (6) make any change in the provisions of the Indenture relating to waivers of past Defaults or the rights of holders of the Notes to receive payments of principal of or premium, if any, or interest on the Notes;	
 	 	
 	      (7) waive a payment required by one of the covenants described above under the caption “— Repurchase at the Option of Holders;”	
 	 	
 	      (8) make any change in the preceding amendment and waiver provisions; or	
 	 	
 	      (9) release any Guarantor from any of its obligations under its Guarantee of the Notes or the Indenture, except in accordance with the terms of the Indenture.	
      Notwithstanding the preceding, without the consent of any holder of the Notes, Amkor and the Trustee may amend or supplement the Indenture or the Notes to:
 	 	
 	      (1) cure any ambiguity, defect or inconsistency;	
 	 	
 	      (2) provide for uncertificated Notes in addition to or in place of certificated Notes;	
 	 	
 	      (3) provide for the assumption of Amkor’s obligations to holders of the Notes in the case of a merger or consolidation or sale of all or substantially all of Amkor’s assets;	
 	 	
 	      (4) make any change that would provide any additional rights or benefits to the holders of Notes or that does not adversely affect the legal rights under the Indenture of any such holder; or	
 	 	
 	      (5) comply with requirements of the SEC in order to effect or maintain the qualification of the Indenture under the Trust Indenture Act of 1939.	
Concerning the Trustee

      If the Trustee becomes a creditor of Amkor or any Guarantor, the Indenture limits its right to obtain payment of claims in certain cases, or to realize on certain property received in respect of any such claim as security or otherwise. Such Trustee will be permitted to engage in other transactions, but if it acquires any conflicting interest, it must eliminate such conflict within 90 days, apply to the SEC for permission to continue or resign.

47

 

      The holders of a majority in principal amount of the then outstanding Notes will have the right to direct the time, method and place of conducting any proceeding for exercising any remedy available to the Trustee, subject to certain exceptions. The Indenture provides that in case an Event of Default shall occur and be continuing, the Trustee will be required, in the exercise of its power, to use the degree of care of a prudent man in the conduct of his own affairs. Subject to such provisions, the Trustee will be under no obligation to exercise any of its rights or powers under the Indenture at the request of any holder of the Notes, unless such holder shall have offered to the Trustee security and indemnity satisfactory to it against any loss, liability or expense.

Governing Law

Registration Rights; Liquidated Damages

      We and the initial purchasers entered into the Registration Rights Agreement on March 12, 2004. Pursuant to the Registration Rights Agreement, we agreed to use commercially reasonable efforts to file with the SEC the exchange offer registration statement on the appropriate form under the Securities Act with respect to the exchange notes. Pursuant to the exchange offer registration statement of which this prospectus is a part, we are offering to the holders of Transfer Restricted Securities pursuant to the exchange offer who are able to make certain representations the opportunity to exchange their Transfer Restricted Securities for exchange notes.

      If (1) the exchange offer is not permitted by applicable law or SEC policy or (2) any holder of Notes that are Transfer Restricted Securities notifies us prior to the 20th business day following the consummation of the exchange offer that (a) it is prohibited by law or SEC policy from participating in the exchange offer, (b) it may not resell the exchange notes acquired by it in the exchange offer to the public without delivering a prospectus, and the prospectus contained in the exchange offer Registration Statement is not appropriate or available for such resales by it, or (c) it is a broker-dealer and holds Notes acquired directly from us or any of our Affiliates, we will file with the SEC a Shelf Registration Statement to register for public resale the Transfer Restricted Securities held by any such holder who provides us with certain information for inclusion in the Shelf Registration Statement.

      For the purposes of the Registration Rights Agreement, “Transfer Restricted Securities” means each Note until:
 	 	
 	      (1) the date on which such Note has been exchanged by a Person other than a broker-dealer for an exchange note in the exchange offer;	
 	 	
 	      (2) following the exchange by a broker-dealer in the exchange offer of a Note for an exchange note, the date on which such exchange note is sold to a purchaser who receives from such broker-dealer on or prior to the date of such sale a copy of the prospectus contained in the exchange offer Registration Statement;	
 	 	
 	      (3) the date on which such Note has been effectively registered under the Securities Act and disposed of in accordance with the Shelf Registration Statement; or	
 	 	
 	      (4) the date on which such Note is distributed to the public pursuant to Rule 144 under the Securities Act.	
48

 

      The Registration Rights Agreement provides that:
 	 	
 	      (1) we will use commercially reasonable efforts to file an exchange offer Registration Statement with the SEC on or prior to July 10, 2004;	
 	 	
 	      (2) we will use commercially reasonable efforts to have the exchange offer Registration Statement declared effective by the SEC on or prior to October 8, 2004;	
 	 	
 	      (3) unless the exchange offer would not be permitted by applicable law or SEC policy, we will:	

 	      (a) commence the exchange offer; and	
 	 	
 	      (b) use commercially reasonable efforts to issue on or prior to 30 business days, or longer, if required by the federal securities laws, after the date on which the exchange offer Registration Statement was declared effective by the SEC, exchange notes in exchange for all Notes tendered prior thereto in the exchange offer; and	

 	      (4) if obligated to file the Shelf Registration Statement, we will use commercially reasonable efforts to file the Shelf Registration Statement with the SEC on or prior to 60 days after such filing obligation arises and to cause the Shelf Registration to be declared effective by the SEC on or prior to 120 days after such obligation arises.	
      If:
 	 	
 	      (1) we fail to file any of the registration statements required by the Registration Rights Agreement on or before the date specified for such filing; or	
 	 	
 	      (2) any of such registration statement is not declared effective by the SEC on or prior to the date specified for such effectiveness (the “Effectiveness Target Date”); or	
 	 	
 	      (3) we fail to consummate the exchange offer within 30 business days of the Effectiveness Target Date with respect to the exchange offer Registration Statement; or	
 	 	
 	      (4) the Shelf Registration Statement or the exchange offer Registration Statement is declared effective but thereafter ceases to be effective or usable in connection with resales of Transfer Restricted Securities during the periods specified in the Registration Rights Agreement (each such event referred to in clauses (1) through (4) above, a “Registration Default”),	
then we will pay Liquidated Damages to each holder of the Notes, with respect to the first 90-day period immediately following the occurrence of the first Registration Default, at a rate equal to 0.25% per annum in principal amount of Transfer Restricted Securities held by such holder for each week or portion thereof. The rate of such Liquidated Damages will increase by 0.25% per annum with respect to each subsequent 90-day period until all Registration Defaults have been cured, up to a maximum amount of Liquidated Damages for all Registration Defaults of 1.00% per annum. If, after the cure of all Registration Defaults then in effect, there is a subsequent Registration Default, the rate of Liquidated Damages for such subsequent Registration Default shall initially be 0.25%, regardless of the Liquidated Damages rate in effect with respect to any prior Registration Default at the time of the cure of such Registration Default.

      All accrued Liquidated Damages will be paid by us on each interest payment date to the holder of the global securities (as defined below) by wire transfer of immediately available funds or by federal funds check and to holders of certificated securities (as defined below) by wire transfer to the accounts specified by them or by mailing checks to their registered addresses if no such accounts have been specified.

      Holders of the Notes will be required to make certain representations to us (as described in the Registration Rights Agreements) in order to participate in the exchange offer and will be required to deliver certain information to be used in connection with the Shelf Registration Statement and to provide comments on the Shelf Registration Statement within the time periods set forth in the Registration Rights Agreement in order to have their Notes included in the Shelf Registration Statement and benefit from the provisions regarding Liquidated Damages set forth above. Holders of the Notes will also be required to suspend their use of the prospectus included in the Shelf Registration Statement under certain circumstances upon receipt of

49

 
written notice to that effect from us. By acquiring Transfer Restricted Securities, a holder will be deemed to have agreed to indemnify us against certain losses arising out of information furnished by such holder in writing for inclusion in any Shelf Registration Statement.

Additional Terms of the Exchange Notes

      The terms of the exchange notes will be identical in all material respects to those of the original notes except that the exchange notes:
 	 	 	
 	• 	will have been registered under the Securities Act and therefore will not be subject to certain restrictions on transfer applicable to the original notes; and	
 	 	 	
 	• 	will not be entitled to certain registration rights under the Registration Rights Agreement, including the provision for Liquidated Damages of up to 1.00% per annum on the original notes.	
      Holders of original notes should review the information set forth under “Risk Factors” and “The Exchange Offer — Consequences of Failure to Exchange.”

64

 

BOOK-ENTRY; DELIVERY AND FORM

The Global Securities

      The original notes are, and the exchange notes will be, issued in the form of one or more global certificates, known as “global securities.” The global securities will be deposited on the date of the acceptance for exchange of the original notes and the issuance of the exchange notes with, or behalf of, DTC and registered in the name of Cede & Co., as DTC’s nominee.

      Exchange notes that are issued as described below under “Issuance of Certificated Securities” will be issued in the form of registered definitive certificates, known as “certificated securities.” Upon the transfer of certificated securities, such certificated securities may, unless the global securities have previously been exchanged for certificated securities, be exchanged for an interest in the global securities representing the principal amount of exchange notes being transferred.

      Persons holding interests in the global securities may hold their interests directly through DTC or indirectly through organizations that are participants in DTC.

      The descriptions of the operations and procedures of DTC, Euroclear and Clearstream set forth below are provided solely as a matter of convenience. These operations and procedures are solely within the control of the respective settlement systems and are subject to change by them from time to time. Neither we, the trustee, nor any paying agent or registrar takes any responsibility for these operations or procedures, and holders of securities are urged to contact the relevant system or its participants directly to discuss these matters.

      DTC has advised us that it is (1) a limited purpose trust company organized under the laws of the State of New York, (2) a “banking organization” within the meaning of the New York Banking Law, (3) a member of the Federal Reserve System, (4) a “clearing corporation” within the meaning of the Uniform Commercial Code, as amended, and (5) a “clearing agency” registered pursuant to Section 17A of the Exchange Act. DTC was created to hold securities for its participants and facilitates the clearance and settlement of securities transactions between participants through electronic book-entry changes to the accounts of its participants, thereby eliminating the need for physical transfer and delivery of certificates. DTC’s participants include securities brokers and dealers, including the initial purchasers, banks and trust companies, clearing corporations and certain other organizations. Indirect access to DTC’s system is also available to other entities such as banks, brokers, dealers and trust companies, referred to as “indirect participants,” that clear through or maintain a custodial relationship with a participant, either directly or indirectly. Investors who are not participants may beneficially own securities held by or on behalf of DTC only through participants or indirect participants.

      Ownership of the exchange notes will be shown on, and the transfer of ownership thereof will be effected only through, records maintained by DTC, with respect to the interests of participants, and the records of participants and the indirect participants, with respect to the interests of persons other than participants.

      The laws of some jurisdictions may require that some types of purchasers of exchange notes take physical delivery of the securities in definitive form. Accordingly, the ability to transfer interests in exchange notes represented by a global security to these persons may be limited. In addition, because DTC can act only on behalf of its participants, who in turn act on behalf of persons who hold interests through participants, the ability of a person having an interest in securities represented by a global security to pledge or transfer the interest to persons or entities that do not participate in DTC’s system, or to otherwise take actions in respect of the interest, may be affected by the lack of a physical definitive security in respect of the interest.

      So long as DTC or its nominee is the registered owner of a global security, DTC or such nominee, as the case may be, will be considered the sole owner or holder of the exchange notes represented by the global security for all purposes under the indenture. Except as provided below, owners of beneficial interests in a global security will not be entitled to have securities represented by the global security registered in their names, will not receive or be entitled to receive physical delivery of certificated securities, and will not be considered the owners or holders thereof under the indenture for any purpose, including with respect to the

65

 
giving of any direction, instruction or approval to the trustee under the indenture. Accordingly, each holder owning a beneficial interest in a global security must rely on the procedures of DTC and, if the holder is not a participant or an indirect participant, on the procedures of the participant through which the holder owns its interest, to exercise any rights of a holder of exchange notes under the indenture or the global security.

      We understand that under existing industry practice, in the event that we request any action of holders of exchange notes, or a holder that is an owner of a beneficial interest in a global security desires to take any action that DTC, as the holder of such global security, is entitled to take, DTC would authorize the participants to take the action and the participants would authorize holders owning through the participants to take the action or would otherwise act upon the instruction of the holders. Neither we nor the trustee will have any responsibility or liability for any aspect of the records relating to, or payments made on account of securities by, DTC, or for maintaining, supervising or reviewing any records of DTC relating to the exchange notes.

      Payments with respect to the principal of, and premium, if any, and interest on, any exchange notes represented by a global security registered in the name of DTC or its nominee on the applicable record date will be payable by the trustee to or at the direction of DTC or its nominee in its capacity as the registered holder of the global security representing the exchange notes under the indenture. Under the terms of the Indenture, we may treat, and the trustee may treat, the persons in whose names the exchange notes, including the global securities, are registered as the owners of the exchange notes for the purpose of receiving payment on the exchange notes and for any and all other purposes whatsoever. Accordingly, neither we nor the trustee has or will have any responsibility or liability for the payment of these amounts to owners of beneficial interests in the global security, including principal, premium, if any, and interest. Payments by the participants and the indirect participants to the owners of beneficial interests in the global securities will be governed by standing instructions and customary industry practice and will be the responsibility of the participants or the indirect participants and DTC.

      Transfers between participants in DTC will be effected in accordance with DTC’s procedures, and will be settled in same-day funds. Transfers between participants in Euroclear or Clearstream will be effected in the ordinary way in accordance with their respective rules and operating procedures.

      Subject to compliance with the transfer restrictions applicable to the securities, cross-market transfers between the participants in DTC, on the one hand, and Euroclear or Clearstream participants, on the other hand, will be effected through DTC in accordance with DTC’s rules on behalf of Euroclear or Clearstream, as the case may be, by its respective depositary; however, such cross-market transactions will require delivery of instructions to Euroclear or Clearstream, as the case may be, by the counterparty in the system in accordance with the rules and procedures and within the established deadlines (Brussels time) of the system. Euroclear or Clearstream, as the case may be, will, if the transaction meets its settlement requirements, deliver instructions to its respective depositary to take action to effect final settlement on its behalf by delivering or receiving interests in the relevant global securities in DTC, and making or receiving payment in accordance with normal procedures for same-day funds settlement applicable to DTC. Euroclear participants and Clearstream participants may not deliver instructions directly to the depositaries for Euroclear or Clearstream.

      Because of time zone differences, the securities account of a Euroclear or Clearstream participant purchasing an interest in a global security from a participant in DTC will be credited, and any such crediting will be reported to the relevant Euroclear or Clearstream participant, during the securities settlement processing day, which must be a business day for Euroclear and Clearstream, immediately following the settlement date of DTC. Cash received in Euroclear or Clearstream as a result of the sale of an interest in a global security by or through a Euroclear or Clearstream participant to a participant in DTC will be received with value on the settlement date of DTC but will be available in the relevant Euroclear or Clearstream cash account only as of the business day for Euroclear or Clearstream following DTC’s settlement date.

      Although DTC, Euroclear and Clearstream have agreed to the foregoing procedures to facilitate transfers of interests in the global securities among participants in DTC, Euroclear and Clearstream, they are under no obligation to perform or to continue to perform such procedures, and such procedures may be discontinued at any time. Neither we nor the trustee will have any responsibility for the performance by DTC, Euroclear or

66

 
Clearstream or their respective participants or indirect participants of their respective obligations under the rules and procedures governing their operations.

Issuance of Certificated Securities

      If (1) we notify the trustee in writing that DTC, Euroclear or Clearstream is no longer willing or able to act as a depositary or clearing system for the exchange notes or DTC ceases to be registered as a clearing agency under the Exchange Act, and a successor depositary or clearing system is not appointed within 90 days of this notice or cessation, (2) we, at our option, notify the trustee in writing that we elect to cause the issuance of exchange notes in definitive form under the indenture, or (3) upon the occurrence and continuation of an event of default under the indenture with respect to any series of exchange notes, then, upon surrender by DTC of the global securities, certificated securities will be issued to each person that DTC identifies as the beneficial owner of the exchange notes represented by the global securities. Upon any such issuance, the trustee is required to register the certificated securities in the name of the person or persons or the nominee of any of these persons and cause the same to be delivered to these persons.

      Neither we nor the trustee shall be liable for any delay by DTC or any participant or indirect participant in identifying the beneficial owners of the related exchange notes and each such person may conclusively rely on, and shall be protected in relying on, instructions from DTC for all purposes, including with respect to the registration and delivery, and the respective principal amounts, of the exchange notes to be issued.

CERTAIN UNITED STATES FEDERAL INCOME TAX CONSIDERATIONS

      This section summarizes some of the U.S. federal income tax considerations relating to the exchange of original notes for exchange notes in the exchange offer and the ownership and disposition of the exchange notes. This summary does not provide a complete analysis of all potential tax considerations. The information provided below is based on existing authorities. These authorities may change, or the Internal Revenue Service (the “IRS”) might interpret the existing authorities differently. In either case, the tax consequences of exchanging the original notes for exchange notes and of owning or disposing of exchange notes could differ from those described below. The summary generally applies only to “U.S. Holders” that hold the notes as “capital assets” (generally, for investment). For this purpose, U.S. Holders include citizens or residents of the United States and corporations organized under the laws of the United States or any state, including the District of Columbia. Trusts are U.S. Holders if they are subject to the primary supervision of a U.S. court and the control of one of more U.S. persons. Special rules apply to beneficial owners of the Notes who are nonresident alien individuals and foreign corporations or trusts (“Non-U.S. Holders”). This summary describes some, but not all, of these special rules. For U.S. federal income tax purposes, income earned through a foreign or domestic partnership or other flow-through entity is attributed to its owners. Accordingly, if a partnership or other flow-through entity holds exchange notes, the tax treatment will depend on the status of the partner or other owner and the activities of the partnership or other entity. The summary generally does not address tax considerations that may be relevant to particular investors because of their specific circumstances, or because they are subject to special rules. Finally, the summary does not describe the effect of the federal estate and gift tax laws on U.S. Holders or the effects of any applicable foreign, state, or local laws.

      INVESTORS SHOULD CONSULT THEIR OWN TAX ADVISORS REGARDING THE APPLICATION OF THE U.S. FEDERAL INCOME TAX LAWS TO THEIR PARTICULAR SITUATIONS AND THE CONSEQUENCES OF FEDERAL ESTATE AND GIFT TAX LAWS, FOREIGN, STATE, AND LOCAL LAWS, AND TAX TREATIES.

Tax Consequences of the Exchange Offer

      An exchange of original notes for exchange notes pursuant to the exchange offer will not be a taxable event for United States federal income tax purposes. Consequently, U.S. Holders and Non-U.S. Holders will not recognize any taxable gain or loss for United States federal income tax purposes as a result of exchanging original notes for exchange notes pursuant to the exchange offer. The holding period of the exchange notes will include the holding period of the original notes, and the tax basis in the exchange notes will be the same as the tax basis in the original notes immediately before the exchange.

Tax Consequences to U.S. Holders of Ownership and Disposition of Exchange Notes

 	Taxation of Interest	
      U.S. Holders will be required to recognize as ordinary income any interest paid or accrued on the exchange notes, in accordance with their regular method of accounting. In general, if the terms of a debt instrument entitle a holder to receive payments other than fixed periodic interest that exceed the issue price of the instrument by more than a de minimis amount, the holder may be required to recognize additional interest as “original issue discount” over the term of the instrument. The original notes were not issued with more than a de minimis amount of original issue discount and thus the exchange notes will not be treated as having original issue discount.

      In certain circumstances, we may be required to make payments to holders of the exchange notes in addition to principal and stated interest. For example, if we do not complete the exchange offer as required by the Registration Rights Agreement, as described under “Description of the Notes -Registration Rights; Liquidated Damages,” we will be required to make additional payments to holders of the notes as liquidated damages. In addition, if we experience a change of control, we will be required to make an offer to repurchase the exchange notes at a price that exceeds the principal amount plus accrued but unpaid interest. See “Description of Notes — Repurchase at the Option of Holders — Offer to Repurchase Upon Change of

68

 
Control.” The original issue discount rules allow contingent payments such as these to be disregarded in computing a holder’s interest income if the contingency is “remote” or the amount of the payment is “incidental.” We believe that only a remote possibility exists that we will experience a change of control or be required to pay liquidated damages because of a failure to fulfill our registration obligations. Our determination in this regard is binding on U.S. Holders unless they disclose their contrary position. If, contrary to expectations, we pay liquidated damages, U.S. Holders would be required to recognize additional ordinary income. If we pay a premium to redeem the exchange notes after a change of control, the premium should result in additional capital gain under the rules described below under the heading “Sale, Exchange or Redemption of the Exchange Notes.”

     	Market Discount	
      If a U.S. Holder acquires an exchange note other than in connection with the exchange offer at a price that is less than its issue price, the amount of such difference is treated as “market discount” for U.S. federal income tax purposes, unless such difference is less than  1/4 of one percent of the principal amount at maturity multiplied by the number of complete years to maturity from the date of acquisition. Under the market discount rules, a U.S. Holder is required to treat any gain on the sale, exchange, retirement or other disposition of an exchange note as ordinary income to the extent of the accrued market discount that has not previously been included in income. If a U.S. Holder disposes of an exchange note which has accrued market discount in a nonrecognition transaction in which the U.S. Holder receives property the basis of which is determined in whole or in part by reference to the basis of the exchange note, the accrued market discount is generally not includible in income at the time of such transaction. Instead, the accrued market discount attaches to the property received in the nonrecognition transaction and is recognized as ordinary income upon the disposition of such property. In general, the amount of market discount that has accrued is determined on a ratable basis, by allocating an equal amount of market discount to each day of every accrual period. A U.S. Holder may, however, elect to determine the amount of accrued market discount allocable to any accrual period under the constant yield method. Any such election applies to all debt instruments acquired by the U.S. Holder on or after the first day of the first taxable year to which the election applies, and is irrevocable without the consent of the IRS. If such an election is made, the U.S. Holder’s tax basis in the exchange notes will be increased by the amount of market discount included in income. Unless a U.S. Holder elects to include market discount in income as it accrues, such U.S. Holder may not be allowed to deduct on a current basis a portion of the interest expense on any indebtedness incurred or continued to purchase or carry exchange notes with market discount.

     	Amortizable Bond Premium	
      If a U.S. Holder purchases an exchange note at a price that exceeds the principal amount of the note, the amount of the difference is referred to as “bond premium” for U.S. federal income tax purposes. The U.S. holder may elect to amortize the bond premium against interest payable on the exchange note. In addition, any bond premium in excess of the interest payable on the exchange note may be deductible over the term of the note. If a U.S. Holder elects to amortize bond premium, the amount of bond premium allocable to each period will be based on a constant yield to maturity over the period the exchange note is held. The amortized bond premium would reduce the U.S. Holder’s tax basis in the exchange note. Any such election applies to all fully taxable bonds held by the U.S. Holder at the beginning of the first taxable year to which the election applies, and all fully taxable bonds acquired thereafter, and is irrevocable without the consent of the IRS. If the election is not made, a U.S. Holder must include the full amount of each interest payment in income as it accrues or is paid, and premium will not be taken into account until principal payments are received on the exchange note or the exchange note is sold or otherwise disposed of.

     	Sale, Exchange or Redemption of the Exchange Notes	
      A U.S. Holder will generally recognize capital gain or loss if the holder disposes of an exchange note in a sale, exchange or redemption. The holder’s gain or loss will equal the difference between the proceeds received by the holder and the holder’s adjusted tax basis in the exchange note. The proceeds received by the holder

69

 
will include the amount of any cash and the fair market value of any other property received for the exchange note. The holder’s tax basis in the exchange note will generally equal the amount the holder paid for the exchange note. The portion of any proceeds that is attributable to accrued interest will not be taken into account in computing the holder’s capital gain or loss. Instead, that portion will be recognized as ordinary interest income to the extent that the holder has not previously included the accrued interest in income. The gain or loss recognized by a holder on a disposition of the exchange note will be long-term capital gain or loss if the holder held the exchange note for more than one year. Long-term capital gains of individual taxpayers are taxed at lower rates than those applicable to ordinary income. The deductibility of capital losses is subject to limitation.

Special Tax Rules Applicable to Non-U.S. Holders Owing and Disposing of Exchange Notes

 	Taxation of Interest	
      Payments of interest to nonresident persons or entities are generally subject to U.S. federal income tax at a rate of 30 percent, collected by means of withholding by the payor. Payments of interest on the exchange notes to most Non-U.S. Holders, however, will qualify as “portfolio interest,” and thus will be exempt from the withholding tax, if the holders certify their nonresident status as described below. The portfolio interest exemption will not apply to payments of interest to a Non-U.S. Holder that
 	 	 	
 	• 	owns, directly or indirectly, at least 10 percent of our voting stock, or	
 	 	 	
 	• 	is a “controlled foreign corporation” that is related to us.	
      In general, a foreign corporation is a controlled foreign corporation if more than 50 percent of its stock is owned, directly or indirectly, by one or more U.S. persons that each owns, directly or indirectly, at least 10 percent of the corporation’s voting stock.

      The portfolio interest exemption and several of the special rules for Non-U.S. Holders described below apply only if the holder certifies its nonresident status. A Non-U.S. Holder can meet this certification requirement by providing a Form W-8BEN or appropriate substitute form to us or our paying agent. If the holder holds the exchange note through a financial institution or other agent acting on the holder’s behalf, the holder will be required to provide appropriate documentation to the agent. The holder’s agent will then be required to provide certification to us or our paying agent, either directly or through other intermediaries. For payments made to a foreign partnership or other flow-through entity, the certification requirements generally apply to the partners or other owners rather than the partnership or other entity, and the partnership or other entity must provide the partners’ or owners’ documentation to us or our paying agent.

 	Sale, Exchange or Redemption of Exchange Notes	
      Non-U.S. Holders generally will not be subject to U.S. federal income tax on any gain realized on the sale, exchange, or other disposition of exchange notes. This general rule, however, is subject to several exceptions. For example, the gain would be subject to U.S. federal income tax if
 	 	 	
 	• 	the gain is effectively connected with the conduct by the Non-U.S. Holder of a U.S. trade or business,	
 	 	 	
 	• 	the Non-U.S. Holder was a citizen or resident of the United States and thus is subject to special rules that apply to expatriates, or	
 	 	 	
 	• 	the Non-U.S. Holder is an individual who is present in the United States for 183 days or more in the year of disposition and certain other conditions are met.	

 	Income or Gains Effectively Connected With a U.S. Trade or Business	
      The preceding discussion of the tax consequences of the purchase, ownership or disposition of exchange notes by a Non-U.S. Holder assumes that the holder is not engaged in a U.S. trade or business. If any interest on the exchange notes or gain from the sale, exchange or other disposition of the exchange notes is effectively connected with a U.S. trade or business conducted by the Non-U.S. Holder, then the income or gain will be

70

 
subject to U.S. federal income tax at the regular graduated rates. If the Non-U.S. Holder is eligible for the benefits of a tax treaty between the United States and the holder’s country of residence, any “effectively connected” income or gain will be subject to U.S. federal income tax only if it is also attributable to a permanent establishment or fixed place of business maintained by the holder in the United States. Payments of interest which are effectively connected with a U.S. trade or business are not subject to the 30 percent withholding tax. To claim exemption from withholding, the holder must certify its qualification, which can be done by filing Form W-8ECI. If the Non-U.S. Holder is a corporation, that portion of its earnings and profits that is effectively connected with its U.S. trade or business would generally be subject to a “branch profits tax.” The branch profits tax rate is generally 30 percent, although an applicable tax treaty might provide for a lower rate.

 	U.S. Federal Estate Tax	
      The estates of nonresident alien individuals are subject to U.S. federal estate tax on property with a U.S. situs. The exchange notes generally will not be U.S. situs property if interest on the exchange notes paid immediately before the death of the holder would have qualified as portfolio interest, exempt from withholding tax as described above under “Special Tax Rules Applicable to Non-U.S. Holders Owning and Disposing of Exchange Notes — Taxation of Interest.” Even if interest paid on the exchange notes would have been portfolio interest, however, the exchange notes might still be U.S. situs property if the interest is also effectively connected with a U.S. trade or business. The U.S. federal estate tax liability of the estate of a nonresident alien may be affected by a tax treaty between the United States and the decedent’s country of residence.

Backup Withholding and Information Reporting

      Unless a U.S. Holder is an exempt recipient, such as a corporation, interest and proceeds received from the sale of the exchange notes generally will be subject to information reporting, and will also be subject to U.S. federal backup withholding tax at the applicable rate (currently 28%) if the holder fails to supply an accurate taxpayer identification number or otherwise fails to comply with applicable U.S. information reporting or certification requirements.

      In general, no backup withholding will be required with respect to payments we make with regard to the exchange notes to a Non-U.S. Holder if the holder has provided us with a Form W-8BEN (or a suitable substitute form) directly or through an intermediary or otherwise establishes an exemption, and we do not have actual knowledge or reason to know that the holder is a U.S. person. However, interest paid to Non-U.S. Holders will be subject to information reporting requirements, even if no tax is required to be withheld from such payments.

      Any amounts withheld under the backup withholding rules will be allowed as a credit against a holder’s U.S. federal income tax liability provided the required information is timely furnished to the IRS.

     The preceding discussion of certain U.S. federal income tax considerations is for general information only. It is not tax advice. Each prospective investor should consult its own tax advisor regarding the particular U.S. federal, state, local, and foreign tax consequences of exchanging, holding, and disposing of our notes, including the consequences of any proposed change in applicable laws.

PLAN OF DISTRIBUTION

      Each broker-dealer that receives exchange notes for its own account pursuant to the exchange offer must acknowledge that it will deliver a prospectus meeting the requirements of the Securities Act in connection with any resale of such exchange notes. This prospectus, as it may be amended or supplemented from time to time, may be used by all persons subject to the prospectus delivery requirements of the Securities Act, including a broker-dealer in connection with resales of exchange notes received in exchange for original notes, where such original notes were acquired as a result of market-making activities or other trading activities. We have agreed that, for a period of up to 180 days after consummation of this exchange offer, we will make this prospectus, as amended or supplemented, available to any broker-dealer that requests it in the letter of transmittal for use in connection with any such resale. In addition, until January 3, 2005, all dealers effecting transactions in the exchange notes may be required to deliver a prospectus.

      Although we have no present plan to acquire any original notes that are not tendered in the exchange offer or to file a registration statement to permit resales of any original notes that are not tendered in the exchange offer, we reserve the right, in our sole discretion, to purchase or make offers for any original notes after the expiration date of the exchange offer, from time to time, through open market or privately negotiated transactions, one or more additional exchange or tender offers, or otherwise, as permitted by law, the Indenture and our other debt agreements. Following consummation of this exchange offer, the terms of any such purchases or offers could differ materially from the terms of this exchange offer.

      We will not receive any proceeds from any sale of exchange notes by brokers-dealers or any other persons. Exchange notes received by broker-dealers for their own account pursuant to the exchange offer may be sold from time to time in one or more transactions in the over-the-counter market, in negotiated transactions, through the writing of options on the exchange notes 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 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-dealer and/or the purchasers of any such exchange notes. Any broker-dealer that resells exchange notes 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 exchange notes may be deemed to be an “underwriter” within the meaning of the Securities Act and any profit of any such resale of exchange notes and any commissions or concessions received by any such persons may be deemed to be underwriting compensation under the Securities Act. The letter of transmittal states that by acknowledging that it will deliver and by delivering a prospectus meeting the requirements of the Securities Act, a broker-dealer will not be deemed to admit that it is an “underwriter” within the meaning of the Securities Act.

      We have agreed to pay all expenses incident to this exchange offer other than commissions or concessions of any brokers or dealers and will indemnify the holders of the original notes (including any broker-dealers) against certain liabilities, including liabilities under the Securities Act.

      The broker-dealer further acknowledges and agrees that, upon receipt of notice from us of the happening of any event which makes any statement in the prospectus untrue in any material respect or which requires the making of any changes in the prospectus to make the statements in the prospectus not misleading, which notice we agree to deliver promptly to the broker-dealer, the broker-dealer will suspend use of the prospectus until we have notified the broker-dealer that delivery of the prospectus may resume and have furnished copies of any amendment or supplement to the prospectus to the broker-dealer.
