5 PROSPECTUS SUMMARY The following summary highlights selected information from this prospectus and may not contain all of the information that is important to you. You should read this prospectus in its entirety for specific terms of the new Senior Notes that we are offering in exchange for the old Senior Notes. AMKOR TECHNOLOGY, INC. Amkor is the world's largest independent provider of semiconductor packaging and test services. We believe that we are also one of the leading developers of advanced semiconductor packaging and test technology. We offer one of the industry's broadest integrated sets of packaging and test services, which are the final procedures necessary to prepare semiconductor devices for further use. Our customers outsource the packaging and testing of semiconductor chips to us in order to benefit from our expertise in the development and implementation of our technology and our advanced manufacturing capabilities. We also market the wafer fabrication services provided by a foundry owned by Anam Semiconductor, Inc. ("ASI"). Our customers include, among others, Agere Systems, Inc., Altera Corporation, Infineon Technologies AG, Intel Corporation, LSI Logic Corporation, Motorola, Inc., Philips Electronics N.V., ST Microelectronics PTE, Texas Instruments, Inc. and Toshiba Corporation. We generate revenues primarily from the sale of semiconductor packaging and test services. In addition, we generate revenue by marketing the wafer fabrication services performed by the foundry owned by ASI. Historically, we performed packaging and test services at our factories in the Philippines and subcontracted for additional services with ASI, which operated four packaging and test facilities in Korea. In May 1999, we acquired K4, one of ASI's packaging and test facilities, for $582.0 million. In May 2000, we acquired ASI's remaining three packaging and test facilities, K1, K2 and K3, for a purchase price of $950.0 million. In connection with our purchase of K1, K2 and K3, we made an additional equity investment in ASI of $459.0 million, and as a result we now own 42% of ASI. With the completion of our acquisition of K1, K2 and K3, we no longer depend upon ASI for packaging or test services, although we continue to market ASI's wafer fabrication services. We were incorporated in Delaware in 1997. Our principal offices are located at 1345 Enterprise Drive, West Chester, PA 19380. Information contained in our website does not constitute part of this prospectus. Our telephone number is (610) 431-9600 and our website can be accessed at www.amkor.com. 1

6 THE EXCHANGE OFFER Old Senior Notes.............. On February 20, 2001, we completed the offering of $500,000,000 aggregate principal amount of our 9.25% Senior Notes due 2008 to Salomon Smith Barney Inc. and Deutsche Banc Alex. Brown Inc., as initial purchasers. The initial purchasers sold the old Senior Notes to "qualified institutional buyers" as defined in Rule 144A under the Securities Act of 1933 or outside the United States in accordance with Regulation S under the Securities Act. We have filed the registration statement of which this prospectus is a part to comply with a registration rights agreement between us and the initial purchasers. Exchange Offer................ We are offering to exchange the old Senior Notes for new Senior Notes in the aggregate principal amount of up to $500,000,000 provided that the old Senior Notes are properly tendered and accepted for exchange. We will issue the new Senior Notes promptly after the expiration of the exchange offer. If you are not prohibited from participating in the exchange offer and you do not tender your old Senior Notes prior to the completion of the exchange offer, you will have no further exchange rights under the registration rights agreement. Accordingly, any old Senior Notes that are not tendered for exchange will continue to be subject to restrictions on transfer. See "Risk Factors -- Consequences of Not Tendering Old Senior Notes." Expiration Date............... The exchange offer will expire at 5:00 p.m., New York City time, on August 29, 2001, or on a later extended date and time as we may decide. Conditions to the Exchange Offer......................... The exchange offer is subject to certain customary conditions. The conditions are limited and relate in general to proceedings or laws that might impair our ability to proceed with the exchange offer. As of the date of this prospectus, none of these events had occurred, and we believe their occurrence to be unlikely. If any such conditions do exist prior to the expiration date, we may take the following actions: - refuse to accept any old Senior Notes and return all previously tendered old Senior Notes; - extend the duration of the exchange offer; or - waive such conditions. Procedures for Tendering Old Senior Notes.................. If you wish to participate in the exchange offer, you must complete, sign and date the letter of transmittal and send it, together with your old Senior Notes to be exchanged and any other required documentation to State Street Bank and Trust Company, as exchange agent, at the address set forth in the letter of transmittal. Brokers, dealers, commercial banks, trust companies and other nominees may tender old Senior Notes which they hold as nominee 2

7 by book-entry transfer. Questions regarding the tender of the old Senior Notes or the exchange offer, generally, must be directed to the exchange agent. Special Procedures for Beneficial Owners......... If you are the beneficial owner of old Senior Notes which are registered in the name of a broker, dealer, commercial bank, trust company or other nominee and you wish to tender the old Senior Notes in the exchange offer, you should contact such registered holder promptly and instruct such registered holder to tender the old Senior Notes on your behalf. If you wish to tender on your own behalf, you must, prior to completing and executing the letter of transmittal and delivering the old Senior Notes, either make appropriate arrangements to register ownership of the old Senior Notes in your own name or obtain a properly completed bond power from the registered holder. The transfer of registered ownership may take considerable time and it may not be possible to complete prior to the expiration date. Guaranteed Delivery Procedures.................... If you wish to tender your old Senior Notes and your old Senior Notes are not immediately available or you cannot deliver your old Senior Notes, the letter of transmittal or any other documents required by the letter of transmittal to the exchange agent, or you cannot complete the procedure for book-entry transfer, then prior to the expiration date you must tender your old Senior Notes according to the guaranteed delivery procedures set forth in "The Exchange Offer -- Guaranteed Delivery Procedures." Withdrawal Rights............. Tenders of old Senior Notes may be withdrawn at any time before 5:00 p.m., New York City time, on the expiration date by delivering a written notice of such withdrawal to the exchange agent in conformity with the procedures set forth under "The Exchange Offer -- Withdrawal of Tenders." Acceptance of Old Notes and Delivery of New Notes......... Subject to the satisfaction or waiver of the conditions of the exchange offer, we will accept for exchange any and all old Senior Notes that are properly tendered in the exchange offer before 5:00 p.m., New York City time, on the expiration date. We will deliver the new Senior Notes promptly following the expiration date. If we do not accept any of your old Senior Notes for exchange, we will return them to you as promptly as practicable after the expiration or termination of the exchange offer without any expense to you. Certain Tax Considerations.... The exchange pursuant to the exchange offer should not result in the recognition of income, gain or loss to you or to us for federal income tax purposes. See "Federal Income Tax Considerations" for a discussion of the material federal income tax consequences of the exchange offer. Exchange Agent................ State Street Bank and Trust Company, the trustee under the Indenture, is serving as exchange agent in connection with the exchange offer. 3

8 CONSEQUENCES OF NOT EXCHANGING OLD SENIOR NOTES If you do not exchange your old Senior Notes for new Senior Notes, you will be unable to offer, sell or otherwise transfer your old Senior Notes except: - in compliance with the registration requirements of the Securities Act and any other applicable securities laws; or - pursuant to an exemption therefrom; or - in a transaction not subject to such securities laws. Old Senior Notes that you do not exchange for new Senior Notes in the exchange offer will continue to bear a legend reflecting such restrictions on transfer. In addition, upon consummation of the exchange offer, you will not be entitled to any rights to have old Senior Notes registered under the Securities Act. We do not intend to register under the Securities Act any old Senior Notes that remain outstanding after completion of the exchange offer (subject to limited exceptions, if applicable). To the extent that old Senior Notes are tendered and accepted in the exchange offer, any trading market for old Notes that remain outstanding after the exchange offers could be adversely affected. See "Risk Factors -- Consequences of Not Tendering Old Senior Notes." The new Senior Notes and any old Senior Notes that remain outstanding after consummation of the exchange offer will vote together as a single class for purposes of determining whether holders of the requisite percentage in outstanding principal amount thereof have taken certain actions or exercised certain rights under the Indenture. TERMS OF NEW SENIOR NOTES The exchange offer applies to up to $500,000,000 aggregate principal amount of our old Senior Notes. The new Senior Notes will evidence the same debt as the old Senior Notes and will be entitled to the benefits of the same indenture as the old Senior Notes. The terms of the new Senior Notes are the same as the terms of the old Senior Notes in all material respects except that the new Senior Notes: - have been registered under the Securities Act, - do not include certain rights to registration under the Securities Act, and - do not contain transfer restrictions or terms with respect to additional interest payments applicable to the old Senior Notes. New Senior Notes Offered...... $500,000,000 in aggregate principal amount of 9.25% Senior Notes due 2008. Maturity...................... February 15, 2008. Interest...................... Interest on the new Senior Notes will accrue at the rate of 9.25% per annum and will be payable in cash in arrears semi-annually on February 15 and August 15 of each year, commencing on August 15, 2001. Ranking....................... The new Senior Notes will be our unsecured senior debt and will have the same ranking as the old Senior Notes: N The new Senior Notes will be effectively subordinated to all of our existing and future secured debt, if any, to the extent of such 4

9 security and to all existing and future debt and other liabilities of our subsidiaries, including trade payables; N The new Senior Notes will rank equally with all of our existing and future unsecured senior debt, including the old Senior Notes and our 9.25% Senior Notes due 2006; and N The new Senior Notes will rank senior to all of our existing and future debt that expressly provides that it is subordinated to the Senior Notes, including our 10.5% Senior Subordinated Notes due 2009 (the "Senior Subordinated Notes") and our outstanding 5.00% Convertible Subordinated Notes due 2007 and our 5.75% Convertible Subordinated Notes due 2006 (collectively, the "Convertible Notes"). At March 31, 2001, the old Senior Notes were: N effectively subordinated to $346.5 million of senior secured debt and $300.0 million of liabilities of our subsidiaries; N ranked equally with our 9.25% Senior Notes due 2006; and N senior to $566.5 million of subordinated debt, including our 10.50% Senior Subordinated Notes due 2009, our 5.00% Convertible Subordinated Notes due 2007, and our 5.75% Convertible Subordinated Notes due 2003. Mandatory Offer to Repurchase.................... If we sell certain assets or experience a Change of Control (as defined in the Indenture), we must offer to repurchase the new Senior Notes at the prices listed in the section entitled "Description of Notes -- Repurchase at the Option of Holders -- Offer to Repurchase Upon a Change of Control." Basic Covenants of the old and new Senior Notes Indenture.... We will issue the new Senior Notes under an indenture (the "Indenture") with State Street Bank and Trust Company, as Trustee. The Indenture will, among other things, restrict our ability and the ability of our subsidiaries to: N incur additional indebtedness; N pay dividends, repurchase stock, prepay subordinated debt and make investments and other restricted payments; N create restrictions on the ability of our subsidiaries to pay dividends or make other payments; N engage in sale and leaseback transactions; N create liens; N enter into transactions with affiliates; and N sell assets or merge with or into other companies. These covenants are subject to important exceptions which are described in the section entitled "Description of the Notes --" under the heading "Certain Covenants." 5

10 Registration Rights........... Holders of the new Senior Notes (other than as set forth below) are not entitled to any registration rights with respect to the new Senior Notes. Pursuant to the registration rights agreement among the initial purchasers of the old Senior Notes and us, we agreed to file an exchange offer registration statement with respect to an offer to exchange the old Senior Notes for the new Senior Notes. The registration statement of which this prospectus is a part constitutes such exchange offer registration statement. Under certain circumstances, certain holders of old Senior Notes (including holders of old Senior Notes who may not participate in the exchange offer) may in certain circumstances require us to file, and cause to become effective, a shelf registration statement under the Securities Act which would cover resales of old Senior Notes by such holders. Use of Proceeds............... We will not receive any proceeds from the exchange offer. RISK FACTORS You should carefully consider all the information set forth in this prospectus and, in particular, you should evaluate the specific risk factors set forth under "Risk Factors," beginning on page 9, for a discussion of certain risks involved in making an investment in the new Senior Notes. 6

(2) Prior to our reorganization in April 1998, our predecessor, Amkor Electronics, Inc. ("AEI"), elected to be taxed as an S Corporation under the Internal Revenue Code of 1986 (the "Code") and comparable state tax laws. As a result, AEI did not recognize any provision for federal income tax expense from January 1, 1994 through April 28, 1998. In accordance with applicable Securities and Exchange Commission regulations, we have provided in our 1998 consolidated financial information the pro forma adjustments for income taxes (unaudited) to reflect the additional U.S. federal income taxes which we would have recorded if AEI had been a C Corporation during these periods. (3) Represents ASI's 40% interest in the earnings of Amkor/Anam Pilipinas, Inc. ("AAP"), one of our subsidiaries in the Philippines. We purchased ASI's interest in AAP with a portion of the proceeds from our initial public offering in May 1998. (4) We have calculated EBITDA by adding: (a) income (loss) before income taxes, equity in income (loss) of investees and minority interest, (b) foreign currency (gain) loss, (c) interest expense, net, (d) non-cash other (income) expense, net and (e) depreciation and amortization. We have included data concerning EBITDA because we understand that investors use it to evaluate our historical ability to service debt. EBITDA is not determined in accordance with U.S. GAAP. EBITDA is not indicative of cash flows from operating activities, and you should not consider EBITDA in isolation, or as an alternative to, or more meaningful than, measures of performance determined in accordance with U.S. GAAP. In addition, EBITDA, as defined here, may not be comparable to similarly titled measures used by other companies. 8

13 RISK FACTORS You should carefully consider the risks described below and the other information contained or incorporated by reference in this prospectus before tendering your old Senior Notes for exchange. The risks and uncertainties described below are not the only ones facing our company. Additional risks and uncertainties that are presently unknown 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 our securities could decline, and you might lose all or part of your investment. You should also carefully consider the risks described in "Risk Factors that May Affect Future Operating Performance" in the section entitled "Management's Discussion and Analysis of Financial Condition and Results of Operation" in our Annual Report on Form 10-K for the fiscal year ended December 31, 2000 and other documents incorporated by reference in this prospectus. 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 RELATED TO AN INVESTMENT IN THE SENIOR NOTES HIGH LEVERAGE AND RESTRICTIVE COVENANTS -- OUR SUBSTANTIAL INDEBTEDNESS COULD ADVERSELY AFFECT THE FINANCIAL HEALTH OF OUR COMPANY AND PREVENT US FROM FULFILLING OUR OBLIGATIONS UNDER THE NEW SENIOR NOTES. Substantial Leverage We now have, and after this exchange offer will continue to have, a significant amount of debt. However, despite current debt levels, the terms of the Indenture governing the new Senior Notes and our other securities do not prohibit us or our subsidiaries from incurring substantially more debt, including debt senior to the new Senior Notes. 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 ratios at March 31, 2001 and for the twelve months ended March 31, 2001: AT MARCH 31, 2001 ----------------- (IN THOUSANDS) Total debt, including current maturities.................... $1,838,026 Stockholders' equity........................................ $1,246,258 Ratio of total debt to stockholders' equity................. 1.5x TWELVE MONTHS ENDED MARCH 31, 2001 ------------------- Ratio of EBITDA to cash interest expense.................... 4.3x Ratio of total debt to EBITDA............................... 2.9x 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. 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. 9

14 Our substantial indebtedness could have important consequences to holders of the new Senior Notes. For example, it could: - make it more difficult for us to satisfy our obligations with respect to the new Senior Notes, - increase our vulnerability to general adverse economic and industry conditions, - 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 debt, 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 new Senior 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 new Senior Notes, which we will be required to repay or refinance. For example, our 5.75% Convertible Subordinated Notes due 2006, our 5.00% Convertible Subordinated Notes due 2007, our 9.25% Senior Notes due 2006 and all amounts outstanding under our Credit Agreement will mature prior to the February 15, 2008 maturity of the new Senior Notes and will be payable in cash unless the holders of the convertible notes elect to convert the principal amount of such notes prior to their maturity into our common stock. In addition, we may need to refinance all or a portion of our debt, including the new Senior Notes, on or before their maturity, and we cannot assure you that we will be able to do so. Additional Borrowings Available Despite current debt levels, the terms of the Indenture 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. EFFECTIVE SUBORDINATION OF THE NEW SENIOR NOTES TO SENIOR SECURED DEBT -- THE NEW SENIOR NOTES ARE EFFECTIVELY SUBORDINATED TO OUR EXISTING SENIOR SECURED DEBT. The new Senior Notes are not secured. Holders of secured debt will have claims that are prior to claims of holders of new Senior Notes to the extent of the assets securing such other debt. At March 31, 2001, the old Senior Notes were effectively subordinated to $346.5 million of secured debt without providing holders of the Senior Notes collateral on a pari passu basis or at all. Under the terms of the Indenture, we are permitted to incur additional secured debt without providing holders of the Senior Notes collateral on a pari passu basis or at all. EFFECTIVE SUBORDINATION OF THE NEW SENIOR NOTES TO LIABILITIES OF OUR SUBSIDIARIES -- YOUR RIGHT TO RECEIVE PAYMENTS ON THE NEW SENIOR 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. We expect distributions from our subsidiaries to be a large source of funds for payment of interest on the Senior Notes. 10

15 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 Senior 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 Senior 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. 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 Senior Notes may receive ratably less than other such creditors or interest holders. At March 31, 2001, the Senior Notes would have been effectively subordinated to $300.0 million of liabilities (including trade payables) of our subsidiaries. FINANCING CHANGE OF CONTROL OFFER -- WE MAY NOT HAVE THE ABILITY TO RAISE THE FUNDS NECESSARY TO FINANCE THE CHANGE OF CONTROL OFFER REQUIRED BY THE INDENTURE. Upon the occurrence of certain specific kinds of change of control events, we will be required to offer to repurchase all outstanding Senior 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 Senior Notes or that restrictions in our future credit facilities may not allow such repurchases. CONSEQUENCES OF NOT TENDERING OLD SENIOR NOTES -- IF YOU DO NOT TENDER YOUR OLD SENIOR NOTES, YOU WILL CONTINUE TO HOLD RESTRICTED SECURITIES. Upon consummation of the exchange offer, we will have no further obligation to register your old Senior Notes, except under limited circumstances. Thereafter, if you do not tender your old Senior Notes in the exchange offer, you will continue to hold restricted securities which may not be offered, sold or otherwise transferred, pledged or hypothecated except pursuant to Rule 144 and Rule 144A under the Securities Act or pursuant to any other exemption from registration under the Securities Act relating to the disposition of securities, provided that an opinion of counsel is furnished to us that such an exemption is available. These restrictions will likely limit the trading market and price for the old Senior Notes. LACK OF PUBLIC MARKET -- BECAUSE THERE IS NO PUBLIC MARKET FOR THE NEW SENIOR NOTES, YOU MAY FIND IT DIFFICULT TO SELL THE NEW SENIOR NOTES. The new Senior Notes are being offered to the holders of the old Senior Notes. Prior to this exchange offer, there has been no existing trading market for any of the old Senior Notes, and a trading market may not develop for the new Senior Notes. We do not intend to apply for listing of the new Senior Notes on any securities exchange or on the Nasdaq National Market. The new Senior Notes may trade at a discount from their initial offering price, depending upon prevailing interest rates, the market for similar securities, our performance and other factors. In connection with the issuance of the old Senior Notes, we were advised by the initial purchasers that they intended to make a market in the new Senior Notes. However, the initial purchasers are not obligated to do so and any such market-making activities may be discontinued at any time without notice. Therefore, we cannot assure you that an active market for the new Senior Notes will develop. 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 Senior Notes may be not collectible within the U.S. If holders of Senior 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. 11

16 USE OF PROCEEDS We will not receive any cash proceeds from the issuance of the new Senior Notes offered in exchange for old Senior Notes. The old Senior Notes will be exchanged for new Senior Notes of like principal amount. Old Senior Notes that are exchanged will be retired and canceled. OUR INDEBTEDNESS AND FINANCING AGREEMENTS As of March 31, 2001, the principal amount of all our indebtedness, calculated on a consolidated basis, was approximately $1,838.0 million. On April 28, 2000 we entered into a credit agreement with various lenders which provided us with $900 million of secured credit facilities (the "Secured Credit Facilities"). On March 30, 2001, the credit agreement was amended and restated (as amended and restated, the "Credit Agreement") and the Senior Secured Credit Facilities were reduced to $546.5 million. The Secured Credit Facilities consist of a $200.0 million revolving credit facility, subject to borrowing base availability, none of which was drawn as of March 31, 2001, and a $346.5 million term loan. The revolving credit facility bears interest at LIBOR plus 2.75% per annum and is payable in full on March 31, 2005. The term loan currently bears interest at LIBOR plus 3.00% per annum and is payable in quarterly installments with a final installment payable September 30, 2005. The interest rates on the revolving credit facility and the term loan are subject to reduction in the event of improvements in our leverage ratio. Amounts borrowed under the revolving credit facility may be repaid and reborrowed. Under the terms of the Secured Credit Facilities, we are required to make mandatory prepayments with a portion of any excess cash flow, net proceeds of any asset sales and net proceeds of any issuance of debt or equity securities, subject to certain exceptions. The Secured Credit Facilities are secured by our domestic assets and those of our domestic subsidiaries, and other investments owned by us and our domestic subsidiaries, including certain intercompany loans and 66% of the stock of our first-tier foreign subsidiaries. The Secured Credit Facilities include various financial and other covenants and events of default, including covenants that restrict our ability to incur debt, pay dividends, make certain investments and payments, repurchase securities and encumber or dispose of assets. We have outstanding $425.0 million of 9.25% Senior Notes due May 1, 2006 that we issued in May 1999. On or after May 1, 2003, we have the right to redeem such notes at the redemption prices specified in the indenture governing such notes. The holders of such notes will have the right to require us to repurchase such notes following the occurrence of a change of control or certain asset sales. We have outstanding $200.0 million of 10.50% Senior Subordinated Notes due May 1, 2009 that we issued in May 1999. At any time prior to May 1, 2002, we have the right to redeem up to 35% of such notes with the cash proceeds of offerings of our common stock at the redemption prices specified in the indenture governing such notes. On or after May 1, 2004, we have the right to redeem such notes at the redemption prices specified in such indenture. The holders of such notes will have the right to require us to repurchase such notes following the occurrence of a change of control or certain asset sales. We have outstanding $258.8 million of 5.00% Convertible Subordinated Notes due March 15, 2007 that we issued in March 2000. The holders have the option to convert such notes into our common stock at any time prior to maturity on March 15, 2007 at $57.34 per share. We have the right to redeem such notes after September 20, 2001 and before March 20, 2003 at the redemption prices specified in the indenture governing such notes, conditioned upon the closing price of our common stock being at or above 150% of the conversion price of such notes for at least 20 trading days within a period of 30 consecutive trading days prior to the date we mail the notice of redemption. On or after March 20, 2003, we have the right to redeem such notes at the prices specified in the indenture governing such notes. The holders of such notes will have the right to require us 12

17 to repurchase such notes following the occurrence of a change of control or a termination of trading of our common stock. We have outstanding $250.0 million of 5.75% Convertible Subordinated Notes due June 1, 2006 that we issued in May 2001. The holders have the option to convert such notes into our Common Stock at any time prior to maturity on June 1, 2006 at $35.00 per share. We have the right to redeem such notes after June 4, 2004 at the redemption prices specified in the indenture governing such notes. The holders of such notes will have the right to require us to repurchase such notes following the occurrence of a change of control or certain asset sales. 13

18 THE EXCHANGE OFFER PURPOSES OF THE EXCHANGE OFFER In issuing the old Senior Notes, we agreed to use our commercially reasonable efforts to cause to become effective a registration statement with respect to the exchange offer (the "Exchange Offer Registration Statement") on or prior to September 18, 2001. We will file with the Securities and Exchange Commission (the "SEC") a shelf registration statement (the "Shelf Registration Statement") if: (1) the exchange offer is not permitted by applicable law or SEC policy; or (2) any holder of old Senior Notes notifies us prior to the 20th day following the consummation of the exchange offer that: (a) it is prohibited by law or SEC policy from participating in the exchange offer; or (b) it may not resell the new Senior Notes it acquired 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; or (c) it is a broker-dealer and owns old Senior Notes acquired directly from us or one of our affiliates. The Shelf Registration Statement will cover resales of old Senior Notes by holders who have provided certain information required by us in connection with the Shelf Registration Statement. We are making the exchange offer to satisfy our obligations under the registration rights agreement into which we entered in connection with the sale of the Old Senior Notes. Once the exchange offer is complete, we will have no further obligation to register any of the old Senior Notes not tendered by the holders for exchange. See "Risk Factors -- Consequences of Not Tendering Old Senior Notes." We filed a copy of the registration rights agreement as an exhibit to the registration statement of which this prospectus is a part. RESALE OF THE NEW SENIOR NOTES We believe that new Senior Notes issued in the exchange offer in exchange for old Senior Notes may be offered for resale, resold and otherwise transferred by their holders without compliance with the registration and prospectus delivery provisions of the Securities Act. Our belief is based on an interpretation by the staff of the SEC set forth in the staff's Exxon Capital Holdings Corp. SEC No-Action Letter (available April 13, 1989), Morgan Stanley & Co., Inc. SEC No-Action Letter (available June 5, 1991), Shearman & Sterling SEC No-Action Letter (available July 7, 1993), and other no-action letters issued to third parties. Any holder who is an "affiliate" of ours or who intends to participate in the exchange offers for the purpose of distributing the new Senior Notes: (1) cannot rely on the interpretation by the staff of the SEC set forth in the above referenced no-action letters, (2) cannot tender its old Senior Notes in the exchange offer, and (3) must comply with the registration and prospectus delivery requirements of the Securities Act in connection with any sale or transfer of the old Senior Notes, unless such sale or transfer is made pursuant to an exemption from such requirements. In addition, each broker-dealer that holds old Senior Notes acquired for its own account as a result of market-making or other trading activities (a "Participating Broker-Dealer") that receives new Senior Notes for 14

19 its own account in exchange for old Senior Notes not acquired directly from us must acknowledge that it will deliver a prospectus in connection with any resale of such new Senior Notes. See "Plan of Distribution." Except as described above, this prospectus may not be used for an offer to resell, resale or other transfer of new Senior Notes. TERMS OF THE EXCHANGE OFFER General. Upon the terms and subject to the conditions of the exchange offer described in this prospectus and the letter of transmittal, we will accept any and all old Senior Notes validly tendered and not withdrawn before 5:00 p.m., New York City time, on the expiration date. We will issue $1,000 principal amount of new Senior Notes in exchange for each $1,000 principal amount of outstanding old Senior Notes accepted in the exchange offers amount of old Senior Notes accepted in the exchange offer. You may tender some or all of your old Senior Notes pursuant to the exchange offer. Old Senior Notes may be tendered only in integral multiples of $1,000 principal amount. As of June 20, 2001, there was $500,000,000 aggregate principal amount of the old Senior Notes outstanding. We are sending this prospectus, together with the letter of transmittal to such registered holders as of July 18, 2001. We arranged for the old Senior Notes to be issued and transferable in book-entry form through the facilities of The Depository Trust Company acting as depositary. The new Senior Notes will also be issued and transferable in book-entry form through DTC. See "-- Book-Entry Transfer; Delivery and Form." We will accept validly tendered old Senior Notes by giving oral (confirmed in writing) or written notice of acceptance to the exchange agent. The exchange agent will act as agent for the tendering holders of old Senior Notes for the purpose of receiving the new Senior Notes from us. If any tendered old Senior Notes are not accepted for exchange because of an invalid tender, the occurrence of certain other events described in this prospectus or otherwise, the certificates for any such unaccepted old Senior Notes will be returned, without expense, to the holder tendering them or the appropriate book-entry transfer will be made, in each case, as promptly as practicable after the expiration date. You 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 old Senior Notes tendered in the exchange offer. We will pay the expenses, other than certain applicable taxes, of the exchange offer. WE ARE NOT MAKING, NOR IS OUR BOARD OF DIRECTORS MAKING, ANY RECOMMENDATION TO YOU AS TO WHETHER TO TENDER OR REFRAIN FROM TENDERING ALL OR ANY PORTION OF YOUR OLD SENIOR NOTES IN THE EXCHANGE OFFER. FURTHERMORE, NO ONE HAS BEEN AUTHORIZED TO MAKE ANY SUCH RECOMMENDATION. YOU MUST MAKE YOUR OWN DECISION WHETHER TO TENDER YOUR OLD SENIOR NOTES IN THE EXCHANGE OFFER AND, IF SO, THE AGGREGATE AMOUNT OF OLD SENIOR NOTES TO TENDER AFTER READING THIS PROSPECTUS AND THE LETTER OF TRANSMITTAL AND CONSULTING WITH YOUR ADVISERS, IF ANY, BASED ON YOUR OWN FINANCIAL POSITION AND REQUIREMENTS. Expiration Date; Extensions; Amendments. The "expiration date" is August 29, 2001. In our sole discretion, we may extend the exchange offer, in which case the term "expiration date" means the latest date to which the exchange offer is extended. To extend the expiration date, we will notify the exchange agent and the record holders of old Senior Notes of any extension by oral (followed by written) notice, before 9:00 a.m., New York City time, on the business day following the previously scheduled expiration date. We may extend the exchange offer for a specified period of time or on a daily basis until 5:00 p.m., New York City time, on the date on which a specified percentage of old Senior Notes are tendered. 15

20 We reserve the right to delay accepting any old Senior Notes, to extend the exchange offer, to amend the exchange offer or to terminate the exchange offer and not accept old Senior Notes not previously accepted if any of the conditions described below in "-- Conditions" occurs and is not waived. Waiver must be given by oral (confirmed in writing) or written notice to the exchange agent as promptly as practicable. If the exchange offer is amended in a manner we determine to be material, we will promptly disclose such amendment in a manner reasonably calculated to inform the holders of such amendment. We will also extend the exchange offer in such circumstances for a period of five to ten business days, depending upon the significance of the amendment and the manner of disclosure to holders of the old Senior Notes, if the exchange offer would otherwise expire during such five to ten business day period. We have no obligation to publish, advertise, or otherwise communicate any public announcement of any delay, extension, amendment or termination of the exchange offer, other than by making a timely release to the Dow Jones News Service. We may make such announcement in any additional ways at our discretion. INTEREST ON THE NEW NOTES AND THE OLD NOTES The old Senior Notes will continue to accrue interest at the rate of 9.25% per annum through (but not including) the date new Senior Notes are issued in exchange for tendered old Senior Notes. Any old Senior Notes tendered or accepted for exchange will continue to accrue interest at the rate of 9.25% per annum in accordance with their terms. From and after the date of issuance of the new Senior Notes, the new Senior Notes will accrue interest at the rate of 9.25% per annum from the last date to which interest was paid on the old Senior Notes. Interest on the new Senior Notes and any old Senior Notes not tendered or accepted for exchange will be payable semi-annually in arrears on February 15 and August 15 of each year, commencing on August 15, 2001. PROCEDURES FOR TENDERING To tender in the exchange offer, you must follow these steps: (a) complete, sign and date the letter of transmittal, or a facsimile of it; (b) have the signatures on the letter guaranteed if required by Instruction 3 of the letter of transmittal; and (c) mail or otherwise deliver such letter of transmittal or such facsimile, together with the old Senior Notes and any other required documents, to the exchange agent before 5:00 p.m., New York City time, on the expiration date. If delivery of the old Senior Notes is made through book-entry transfer into the exchange agent's account at DTC, you must tender the old Senior Notes in accordance with DTC's Automated Tender Offer Program (ATOP) procedures. See "-- Book-Entry Transfer; Delivery and Form." Your tender of old Senior Notes will constitute an agreement between us in accordance with the terms and subject to the conditions set forth in this prospectus and in the letter of transmittal. You must deliver all documents for tender to the exchange agent at its address set forth below. You may also request your brokers, dealers, commercial banks, trust companies or nominees to effect the above transactions for you. THE METHOD OF DELIVERY OF CERTIFICATES, THE LETTER OF TRANSMITTAL AND ALL OTHER REQUIRED DOCUMENTS, IS AT YOUR OPTION AND YOUR SOLE RISK. DOCUMENTS ARE DELIVERED ONLY WHEN ACTUALLY RECEIVED BY THE EXCHANGE AGENT. IF DELIVERY IS BY MAIL, WE RECOMMEND REGISTERED MAIL, RETURN RECEIPT REQUESTED, PROPERLY INSURED, OR AN OVERNIGHT DELIVERY SERVICE. IN ALL CASES, YOU SHOULD ALLOW SUFFICIENT TIME TO INSURE TIMELY DELIVERY. 16

21 Only a holder of old Senior Notes may tender such old Senior Notes in the exchange offer. The term "holder" with respect to the exchange offer means any person in whose name old Senior Notes are registered on our books or any other person who has obtained a properly completed bond power from the registered holder. If your old Senior Notes are registered in the name of your broker, dealer, commercial bank, trust company or other nominee and you wish to tender your old Senior Notes, you should contact such registered holder promptly and instruct such registered holder to tender on your behalf. If your old Senior Notes are so registered and you wish to tender on your own behalf, you must, prior to completing and executing the letter of transmittal and delivering your old Senior Notes, either make appropriate arrangements to register ownership of the old Senior Notes in your name or obtain a properly completed bond power from the registered holder. The transfer of record ownership may take considerable time. Signatures on a letter of transmittal or 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., or a commercial bank or trust company having an office or correspondent in the U.S. (an "Eligible Institution"). Signatures do not need to be guaranteed if the old Senior Notes are tendered (1) by a registered Holder who has not completed the box entitled "Special Payment Instructions" or "Special Delivery Instructions" on the letter of transmittal or (2) for the account of an Eligible Institution. If the letter of transmittal is signed by a person other than the registered holder of any old Senior Notes listed on the letter, such old Senior Notes must be endorsed or accompanied by appropriate bond powers signed as the name of the registered holder or holders appears on the old Senior Notes. If the letter of transmittal or any old Senior Notes or bond powers are signed by trustees, executors, administrators, guardians, attorneys-in-fact, officers of corporations or others acting in a fiduciary or representative capacity, such persons must indicate their capacity when signing. Unless waived by us, you must then submit evidence satisfactory to us of their authority to so act with the letter of transmittal. We will determine in our sole discretion all questions as to the validity, form, eligibility (including time of receipt) and acceptance of tendered old Senior Notes and withdrawal of tendered old Senior Notes. Our determination will be final and binding. We reserve the absolute right to reject any and all old Senior Notes not properly tendered or any old Senior Notes acceptance of which would, in the opinion of our counsel, be unlawful for us to accept. We also reserve the right to waive any defects, irregularities or conditions of tender as to particular old Senior Notes. Our interpretation of the terms and conditions of the exchange offer (including the instructions in the letter of transmittal) will be final and binding on all parties. Unless waived, any defects or irregularities in connection with tenders of old Senior Notes must be cured within such time as we determine. No one is under any duty to give notification of defects or irregularities with respect to tenders of old Senior Notes, nor will any person incur any liability for failure to give such notification. Old Senior Notes are not properly tendered until such irregularities have been cured or waived. Any old Senior Notes received by the exchange agent that are not properly tendered and as to which the defects or irregularities have not been cured or waived will be returned by the exchange agent to the tendering holders of such old Senior Notes, unless otherwise provided in the letter of transmittal, as soon as practicable after the expiration date. In addition, we reserve the right in our sole discretion: - to purchase or make offers for any old Senior Notes that remain outstanding after the expiration date; - to terminate the exchange offer as described in "-- Conditions;" and - to the extent permitted by applicable law, purchase old Senior Notes in the open market, in privately negotiated transactions or otherwise. The terms of any such purchases or offers could differ from the terms of the exchange offer. 17

22 By tendering, you will represent to us, among other things, that: - the new Senior Notes you acquire in the exchange offer are being obtained in the ordinary course of your business; - you have no arrangement with any person to participate in the distribution of such new Senior Notes; and - you are not an "affiliate," as defined under Rule 405 of the Securities Act, of ours. If you are a Participating Broker-Dealer that will receive new Senior Notes for your own account in exchange for old Senior Notes that were not acquired directly from us, by tendering you will acknowledge that you will deliver a prospectus in connection with any resale of such new Senior Notes. See "Plan of Distribution." BOOK-ENTRY TRANSFER; DELIVERY AND FORM The old Senior Notes were initially in the form of one or more registered global notes without interest coupons and were registered in the name of the Depository Trust Company ("DTC"). The new Senior Notes exchanged for the old Notes represented by the global old Senior Notes will be represented by global new Senior Notes in fully registered form, registered in the name of the nominee of DTC. The global new Senior Notes will be exchangeable for definitive new Senior Notes in registered form, in denominations of $1,000 principal amount and integral multiples of $1,000. The new Senior Notes in global form will trade in DTC's same-day funds settlement system, and therefore secondary market trading activity in the new Senior Notes will settle in immediately available funds. We understand that the exchange agent will make a request promptly after the date of this prospectus to establish an account with respect to the old Senior Notes at DTC for the purpose of facilitating the exchange offer. Subject to the establishment of this account, any financial institution that is a participant in DTC's system may make book-entry delivery of old Senior Notes by causing DTC to transfer such old Senior Notes into the exchange agent's account with respect to the old Senior Notes in accordance with DTC's ATOP procedures for such book-entry transfers. Although delivery of the old Senior Notes may be effected through book-entry transfer into the exchange agent's account at DTC, the exchange for old Senior Notes so tendered will be made only after the following two conditions are met: - First, DTC must timely confirm (a "Book-Entry Confirmation") such book-entry transfer of the old Notes into the exchange agent's account. - Second, the exchange agent must timely receive a Book-Entry Confirmation with a message, transmitted by DTC and received by the exchange agent and forming part of the Book-Entry Confirmation, which states that DTC has received express acknowledgment from a participant tendering old Senior Notes that such participant has received and agrees to be bound by the terms of the letter of transmittal, and that such agreement may be enforced against such participant. GUARANTEED DELIVERY PROCEDURES If your old Senior Notes are not immediately available or if you cannot deliver your old Senior Notes, the letter of transmittal or any other required documents to the exchange agent prior to the expiration date, you may effect a tender if: (1) the tender is made through an Eligible Institution; (2) before the expiration date, the exchange agent receives from such Eligible Institution a properly completed and duly executed notice of guaranteed delivery (by facsimile transmission, mail or hand 18

23 delivery) setting forth the name and address of the holder of the old Senior Notes, the certificate number or numbers of such old Senior Notes and the principal amount of old Senior Notes tendered, stating that the tender is being made thereby and guaranteeing that, within three New York Stock Exchange trading days after the expiration date, the letter of transmittal (or facsimile of such letter) together with the certificate(s) representing the old Senior Notes to be tendered in proper form for transfer and any other documents required by the letter of transmittal, or a Book-Entry Confirmation, as the case may be, will be delivered by the Eligible Institution to the exchange agent; and (3) such properly completed and executed letter of transmittal (or facsimile of such letter), as well as the certificate(s) representing all tendered old Senior Notes in proper form for transfer and all other documents required by the letter of transmittal, or a Book-Entry Confirmation, as the case may be, are received by the exchange agent within three New York Stock Exchange trading days after the expiration date. Upon request of the exchange agent, a notice of guaranteed delivery will be sent to holders who wish to tender their old Senior Notes according to the guaranteed delivery procedures set forth above. WITHDRAWAL OF TENDERS Except as otherwise described in this prospectus, tenders of old Senior Notes may be withdrawn at any time before 5:00 p.m., New York City time, on the expiration date. To withdraw a tender of old Senior Notes in the exchange offer, the exchange agent must receive a written or facsimile transmission notice of withdrawal at its address set forth in this prospectus before 5:00 p.m., New York City time, on the expiration date. See "-- Exchange Agent." Any such notice of withdrawal must: (1) specify the name of the person having deposited the old Senior Notes to be withdrawn (the "Depositor"); (2) identify the old Senior Notes to be withdrawn (including the certificate number or numbers and principal amount of such old Senior Notes); (3) be signed by the holder in the same manner as the original signature on the letter of transmittal by which the old Senior Notes were tendered (including any required signature guarantees) or be accompanied by documents of transfer sufficient to have the trustee with respect to the old Senior Notes register the transfer of the old Senior Notes into the name of the person withdrawing the tender; and (4) specify the name in which any the old Senior Notes are to be registered, if different from that of the Depositor. We will determine all questions as to the validity, form and eligibility (including time of receipt) of such notices and our determination will be final and binding on all parties. Any old Senior Notes so withdrawn will be deemed not to have been validly tendered for purposes of the exchange offer and no new Senior Notes will be issued with respect thereto unless the old Senior Notes so withdrawn are validly retendered. Any old Senior Notes which have been tendered but which are not accepted for exchange will be returned to their holder without cost to such holder as soon as practicable after withdrawal, rejection of tender or termination of the exchange offer. Properly withdrawn old Senior Notes may be retendered by following one of the procedures, described above under "-- Procedures for Tendering" at any time before the expiration date. 19

24 CONDITIONS Notwithstanding any other term of the exchange offer, we will not be required to accept for exchange, or exchange new Senior Notes for, any old Senior Notes not accepted for exchange. We may terminate the exchange offer as provided in this prospectus before accepting old Senior Notes, if any of the following conditions exist: (1) the exchange offer, or the making of any exchange by a holder, violates applicable law or any applicable interpretation of the SEC; (2) any action or proceeding is instituted or threatened in any court or by or before any governmental agency with respect to the exchange offer which, in our sole judgment, might impair our ability to proceed with the exchange offer; (3) any law, statute, rule or regulation is adopted or enacted which, in our sole judgment, might materially impair our ability to proceed with the exchange offer; (4) trading on the New York Stock Exchange or generally in the U.S. over-the-counter market is suspended by order of the SEC or any other governmental authority which, in our judgment, would reasonably be expected to impair our ability to proceed with the exchange offer; or (5) a stop order is issued by the SEC or any state securities authority suspending the effectiveness of the registration statement or proceedings are initiated or, to our knowledge, threatened for that purpose. If any such conditions exist, we may - refuse to accept any old Senior Notes and return all tendered old Senior Notes to exchanging holders; - extend the exchange offer and retain all old Senior Notes tendered prior to the expiration of the exchange offers, subject, however, to the rights of holders to withdraw such old Senior Notes (see "-- Withdrawal of Tenders"); or - waive certain of such conditions with respect to the exchange offers and accept all properly tendered old Senior Notes which have not been withdrawn or revoked. If such waiver constitutes a material change to the exchange offer, we will promptly disclose such waiver in a manner reasonably calculated to inform holders of old Senior Notes of such waiver. The conditions described above are for our sole benefit. We may assert any condition regardless of the circumstances giving rise to any such condition. We may waive any condition in whole or in part at any time and from time to time in our sole discretion. We are not waiving these rights by failing to exercise them. These rights are ongoing and may be asserted at any time and from time to time. EXCHANGE AGENT We appointed State Street Bank and Trust Company as exchange agent for the exchange offer.

We will pay the exchange agent and solicitor reasonable and customary fees for their services and will reimburse it for its reasonable out-of-pocket expenses in connection therewith. 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 and related documents to the beneficial owners of the old Senior Notes, and in handling or forwarding tenders for exchange. We will pay the cash expenses to be incurred in connection with the exchange offer. We estimate these cash expenses will aggregate approximately $150,000, including fees and expenses of the exchange agent, the trustee under the indenture, the solicitor and accounting and legal fees. We will pay all transfer taxes, if any, applicable to the exchange of old Senior Notes in the exchange offer. The amount of any such transfer taxes (whether imposed on the registered holder or any other persons) will be payable by the tendering holder if: (1) certificates representing new Senior Notes or old Senior Notes for principal amounts at maturity not tendered or accepted for exchange are to be delivered to, or are to be registered in the name of, any person other than the registered holder of the old Senior Notes tendered; (2) tendered old Senior Notes are registered in the name of any person other than the person signing the letter of transmittal; or (3) a transfer tax is imposed for any reason other than the exchange of old Senior Notes in the exchange offer. In such circumstances, you must submit satisfactory evidence of payment of such taxes or exception from such taxes with the letter of transmittal or the amount of such transfer taxes will be billed directly to you. ACCOUNTING TREATMENT The new Senior Notes will be recorded at the same carrying value as the old Senior Notes, which is face value as reflected in our accounting records on the date of the exchange offer. Accordingly, no gain or loss for accounting purposes will be recognized upon completion of the exchange offers. The issuance costs incurred in connection with the exchange offer will be capitalized and amortized over the term of the new Senior Notes. 21

26 DESCRIPTION OF THE NOTES GENERAL The new Senior Notes will be issued pursuant to an Indenture between the Company and State Street Bank and Trust Company, as trustee. The terms of the new Senior Notes include those stated in the Indenture and those made part of the Indenture by reference to the Trust Indenture Act of 1939, as amended (the "Trust Indenture Act"). The new Senior Notes are subject to all such terms, and holders of new Senior Notes are referred to the Indenture and the Trust Indenture Act for a statement of such terms. The following summary of the material provisions of the Indenture and the Registration Rights Agreement does not purport to be complete and is qualified in its entirety by reference to such agreements, including the definitions in those agreements of certain terms used below. Copies of such agreements have been filed as exhibits to our Quarterly Report on Form 10-Q for the quarter ended March 31, 2001, which has been incorporated by reference in this prospectus and is available from the SEC or as set forth under "Available Information." The definitions of certain terms used in the following summary are set forth below under "--Certain Definitions." For purposes of the following summary, the term "Company" refers only to Amkor Technology, Inc. and not to any of its Subsidiaries and the term "Senior Notes" refers to the old and new Senior Notes. DESCRIPTION OF THE SENIOR NOTES RANKING The Senior Notes: - are general obligations of the Company; - are 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; - are equal in right of payment with all of our existing and future unsecured senior debt, including our 9.25% Senior Notes due May 1, 2006; and - are senior in right of payment to all of our existing and future debt that expressly provides that it is subordinated to the Senior Notes, including our 10.50% Senior Subordinated Notes due 2009, our 5.00% Convertible Subordinated Notes due 2007 and our 5.75% Convertible Subordinated Notes due 2006. The Senior Notes are "Designated Senior Debt" for purposes of the indentures governing our 10.50% Senior Subordinated Notes due 2009, our and our 5.00% Convertible Subordinated Notes due 2007 and our 5.75% Convertible Subordinated Notes due 2006. As of March 31, 2001, the Company had total senior secured debt of approximately $346.5 million. In addition, our subsidiaries would have had total liabilities of approximately $300.0 million. The Indenture will permit us to incur additional senior secured debt. 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 Senior 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 Senior 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 Senior Notes to participate in the distribution of the proceeds of those assets) will effectively be subordinated by 22

27 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 the Company. If the Company 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 which 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 Senior Notes may receive ratably less than other such creditors or interest holders. As of the date of the Indenture, all of our Subsidiaries other than Amkor Iwate, Co., Ltd., will be "Restricted Subsidiaries." However, under the circumstances described below under the subheading "-- 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 Senior Notes will mature on February 15, 2008. Interest on the Senior Notes will accrue at the rate of 9.25% per annum and will be payable semi-annually in arrears on February 15 and August 15, commencing on August 15, 2001. The Company will make each interest payment to the Holders of record of the Senior Notes on the immediately preceding February 1 and August 1. Interest on the Senior 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 Senior Notes is subject to increase if the Company 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; Liquidation Damages." All references to interest on the Senior Notes include any such Liquidated Damages that may be payable. The Company will issue Senior Notes in denominations of $1,000 and integral multiples of $1,000. REDEMPTION The Company is not entitled to redeem the Senior Notes prior to maturity. REPURCHASE AT THE OPTION OF HOLDERS Offer to Repurchase Upon Change of Control If a Change of Control occurs, each Holder of Senior Notes will have the right to require the Company to repurchase all or any part (equal to $1,000 or an integral multiple thereof) of that Holder's Senior Notes pursuant to the Change of Control Offer. In the Change of Control Offer, the Company will offer a Change of Control Payment in cash equal to 101% of the aggregate principal amount of Senior Notes repurchased plus accrued and unpaid interest thereon, if any, to the date of purchase. Within 30 days following any Change of Control, the Company will mail a notice to each Holder of Senior Notes describing the transaction or transactions that constitute the Change of Control and offering to repurchase Senior 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. The Company will comply with the requirements of Rule 14e-1 under the 23

28 Exchange Act and any other securities laws and regulations thereunder to the extent such laws and regulations are applicable in connection with the repurchase of the Senior Notes as a result of a Change of Control. On the Change of Control Payment Date, the Company will, to the extent lawful: (1) accept for payment all Senior 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 Senior Notes or portions thereof so tendered; and (3) deliver or cause to be delivered to the Trustee the Senior Notes so accepted together with an officers' certificate stating the aggregate principal amount of Senior Notes or portions thereof being purchased by the Company. The Paying Agent will promptly mail to each Holder of Senior Notes so tendered the Change of Control Payment for such Senior Notes, and the Trustee will promptly authenticate and mail (or cause to be transferred by book entry) to each Holder a new Senior Note equal in principal amount to any unpurchased portion of the Senior Notes surrendered, if any; provided that each such new Senior Note will be in a principal amount of $1,000 or an integral multiple thereof. The Company 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 the Company 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 Senior Notes to require that the Company repurchase or redeem the Senior Notes in the event of a takeover, recapitalization or similar transaction. The Company 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 the Company and purchases all Senior 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 the Company 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 Senior Notes to require the Company to repurchase such Senior Notes as a result of a sale, lease, transfer, conveyance or other disposition of less than all of the assets of the Company 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 The Company will not, and will not permit any of its Restricted Subsidiaries to, consummate an Asset Sale unless: (1) the Company (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 Company's Board of Directors; and 24

29 (3) at least 75% of the consideration therefor received by the Company or such Restricted Subsidiary is in the form of cash or other Qualified Proceeds. Within 365 days after the receipt of any Net Proceeds from an Asset Sale, the Company 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 of 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, the Company 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, the Company will make an Asset Sale Offer to all Holders of Senior Notes and all holders of other Indebtedness that is pari passu with the Senior 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 Senior 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, the Company may use such Excess Proceeds for any purpose not otherwise prohibited by the Indenture. If the aggregate principal amount of Senior Notes and such other pari passu Indebtedness tendered into such Asset Sale Offer exceeds the amount of Excess Proceeds, the Trustee shall select the Senior 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 The Company 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 the Company's or any of its Restricted Subsidiaries' Equity Interests (including, without limitation, any payment in connection with any merger or consolidation involving the Company or any of its Restricted Subsidiaries) or to the direct or indirect holders of the Company'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 the Company or to the Company or a Restricted Subsidiary of the Company); (2) purchase, redeem or otherwise acquire or retire for value (including, without limitation, in connection with any merger or consolidation involving the Company) any Equity Interests of the Company or any direct or indirect parent of the Company or any Restricted Subsidiary of the Company (other than any such Equity Interests owned by the Company or any Restricted Subsidiary of the Company); 25

30 (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; and (2) the Company 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 the Company and its Restricted Subsidiaries after May 13, 1999 (the date of the indenture governing the last senior notes we issued) (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 the Company for the period (taken as one accounting period) from the beginning of the fiscal quarter commencing on July 1, 1999 to the end of the Company'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 the Company since May 13, 1999 as a contribution to its common equity capital or from the issue or sale of Equity Interests of the Company (other than Disqualified Stock) (other than Equity Interests (or Disqualified Stock or debt securities) sold to a Subsidiary of the Company), plus (c) to the extent that any Restricted Investment that was made after May 13, 1999 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 the Company or any Restricted Subsidiary issued after May 13, 1999 is reduced on the Company's consolidated balance sheet (if prepared in accordance with GAAP as of the date of determination) and (ii) Disqualified Stock of the Company issued after May 13, 1999 (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 the Company, less, in each case, any cash distributed by the Company upon such conversion or exchange, plus (e) to the extent that any Investment in any Unrestricted Subsidiary that was made after May 13, 1999 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 the Company or any Restricted 26

31 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 the Company or any Restricted Subsidiary that is subordinated to the Senior Notes or of any Equity Interests of the Company 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 the Company) of, Equity Interests (other than Disqualified Stock) of the Company or any subordinated Indebtedness of the Company; 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 the Company or any Restricted Subsidiary that is subordinated to the Senior Notes with the net cash proceeds from the incurrence of Permitted Refinancing Indebtedness; (4) the payment of any dividend by a Restricted Subsidiary of the Company 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 the Company or any Restricted Subsidiary of the Company held by any employee of the Company 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 2003 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 May 3, 2001 or September 20, 2001, respectively pursuant to the terms thereof, or (ii) the honoring by the Company of any conversion request by a holder of either such convertible notes (including the payment by the Company 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 the Company; (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 $25.0 million; (9) the repurchase of Equity Interests of the Company that may be deemed to occur upon the exercise of stock options if such Equity Interests represent a portion of the exercise price thereof; 27

32 (10) any payments to one or more shareholders of the Company in connection with settling shareholder obligations for income taxes in respect of tax periods ending prior to the conversion of the Company from "S" corporation status to "C" corporation status; (11) in the case of an Asset Sale, any Asset Sale Offer after the Company has complied with its obligations to the Holders of the Senior 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 the Company 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 asset(s) or securities proposed to be transferred or issued by the Company 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 The Company 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 the Company 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 the Company and any Restricted Subsidiary that is a Guarantor may incur Indebtedness (including Acquired Debt), and the Company may issue Disqualified Stock, and any Restricted Subsidiary that is a Guarantor may issue preferred stock, if the Consolidated Interest Expense Coverage Ratio for the Company's most recently ended four full fiscal quarters (the "Reference Period") for which internal financial statements are available immediately preceding the date on which such additional Indebtedness is incurred or such Disqualified Stock is issued would have been at least 2.5 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 the Company 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 the Company plus 50% of the consolidated inventory of the Company; (2) the incurrence by the Company and its Subsidiaries of Existing Indebtedness; (3) the incurrence by the Company and any Guarantor of Indebtedness represented by the Senior Notes, and any Subsidiary Guarantees; (4) the incurrence by the Company 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 the Company or such Restricted Subsidiary 28

33 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 10% of the Company's Consolidated Net Assets; (5) the incurrence by the Company 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 clauses (2), (3), (5), (13) or (14) of this paragraph; (6) the incurrence by the Company or any of its Restricted Subsidiaries of intercompany Indebtedness between or among the Company and any of its Restricted Subsidiaries; provided, however, that: (a) if the Company 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 Senior Notes, in the case of the Company, 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 the Company 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 the Company or a Wholly Owned Restricted Subsidiary thereof; shall be deemed, in each case, to constitute an incurrence of such Indebtedness by the Company or such Restricted Subsidiary, as the case may be, that was not permitted by this clause (6); (7) the incurrence by the Company 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 the Company or any of the Guarantors of Indebtedness of the Company or a Restricted Subsidiary of the Company that was permitted to be incurred by another provision of this covenant; (9) the incurrence by the Company'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 the Company 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 the Company or a Restricted Subsidiary of the Company 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 the Company or any Restricted Subsidiary of the Company; and 29

34 (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 the Company 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 the Company 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 the Company 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 $25.0 million. Indebtedness or preferred stock of any Person which is outstanding at the time such Person becomes a Restricted Subsidiary of the Company (including upon designation of any Subsidiary or other Person as a Restricted Subsidiary) or is merged with or into or consolidated with the Company or a Restricted Subsidiary of the Company shall be deemed to have been incurred at the time such Person becomes such a Restricted Subsidiary of the Company or is merged with or into or consolidated with the Company or a Restricted Subsidiary of the Company, as applicable. The Company will not incur any Indebtedness (including Permitted Debt) that is contractually subordinated in right of payment to any other Indebtedness of the Company unless such Indebtedness is also contractually subordinated in right of payment to the Senior Notes on substantially identical terms; provided, however, that no Indebtedness of the Company shall be deemed to be contractually subordinated in right of payment to any other Indebtedness of the Company solely by virtue of any Liens, Guarantees, maturity of payments or structural seniority. 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, the Company will, in 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 The Company 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 30

35 hereafter acquired, except Permitted Liens, unless the Senior 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 The Company 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 the Company or any of the Company's Restricted Subsidiaries, or with respect to any other interest or participation in, or measured by, its profits, or pay any indebtedness owed to the Company or any of the Company's Restricted Subsidiaries; (2) make loans or advances to the Company or any of the Company's Restricted Subsidiaries; or (3) transfer any of its properties or assets to the Company or any of the Company'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, replacement 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 Senior Notes; (3) applicable law; (4) any instrument governing Indebtedness or Capital Stock of a Person acquired by the Company 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 non-assignment provisions in leases, licenses or other contracts entered into in the ordinary course of business and consistent with past practices; (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; 31

36 (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 the Company 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 The Company may not, directly or indirectly: (1) consolidate or merge with or into another Person (whether or not the Company is the surviving corporation); or (2) 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) the Company is the surviving corporation; or (b) the Person formed by or surviving any such consolidation or merger (if other than the Company) 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 the Company) or the Person to which such sale, assignment, transfer, conveyance or other disposition shall have been made assumes all the obligations of the Company under the Senior 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 the Company (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 the Company, the Company or the Person formed by or surviving any such consolidation or merger (if other than the Company) 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) the Company 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. In addition, the Company 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 the Company to any of its Wholly Owned Restricted Subsidiaries. 32

37 Transactions with Affiliates The Company 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 the Company or the relevant Restricted Subsidiary than those that would have been obtained in a comparable transaction by the Company or such Restricted Subsidiary with an unrelated Person; and (2) the Company 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 Officers' 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) the Company 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 the Company shall have determined that any such amendment, modification or supplement will not have a material adverse economic effect on the Company and its Subsidiaries, taken as a whole, and (ii) the Company 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), the Company 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 the Company 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 to be Affiliate Transactions and, therefore, will not be subject to the provisions of the prior paragraphs: (1) any employment agreement or arrangement entered into by the Company or any of its Restricted Subsidiaries or any employee benefit plan available to employees of the Company and its Subsidiaries generally, in each case in the ordinary course of business and consistent with the past practice of the Company or such Restricted Subsidiary; (2) Affiliate Transactions between or among the Company and/or its Restricted Subsidiaries; 33

38 (3) payment of reasonable directors fees to Persons who are not otherwise Affiliates of the Company and indemnity provided on behalf of officers, directors and employees of the Company or any of its Restricted Subsidiaries as determined in good faith by the Board of Directors of the Company; (4) Any Affiliate Transactions pursuant to which the Company 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 the Company of amounts payable by the Company 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 the Company 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 the Company or the relevant Restricted Subsidiary than those that would have been obtained in a comparable transaction by the Company or such Restricted Subsidiary with an unrelated Person and thus shall be permitted under this "Transactions with Affiliates" covenant. Sale and Leaseback Transactions The Company will not, and will not permit any of its Subsidiaries to, enter into any sale and leaseback transaction; provided that the Company or any Restricted Subsidiary may enter into a sale and leaseback transaction if: (1) the Company 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 the Company 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 the Company 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 Senior Notes then outstanding, the Company will not amend, modify or alter the indenture governing the 10.25% Senior Subordinated Notes due 2009 in any way to: (1) increase the rate of or change the time for payment of interest on any 10.25% Senior Subordinated Notes due 2009; 34

39 (2) increase the principal of, advance the final maturity date of or shorten the Weighted Average Life to Maturity of any 10.25% Senior Subordinated Notes due 2009; (3) alter the redemption provisions or the price or terms at which the Company is required to offer to purchase any 10.25% Senior Subordinated Notes due 2009; or (4) amend the subordinated provisions of Article 10 contained in the indenture governing the 10.25% Senior Subordinated Notes due 2009. Subsidiary Guarantees If the Company 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. Each Subsidiary Guarantee will be subordinated to the prior payment in full of all Permitted Bank Debt of that Subsidiary Guarantor, and senior in right of payment to any future subordinated Indebtedness of such Subsidiary Guarantor. 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 the Company 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 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 The Company 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 the Company to any Person (other than the Company or a Wholly Owned Restricted Subsidiary of the Company), 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, the Company will not permit any Wholly Owned Restricted Subsidiary of the Company 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 the Company or a Wholly Owned Restricted Subsidiary of the Company unless immediately following such issuance the Wholly Owned Restricted Subsidiary is a Restricted Subsidiary. 35

40 METHODS OF RECEIVING PAYMENTS ON THE SENIOR NOTES If a Holder has given wire transfer instructions to the Company, the Company will make all principal, premium and interest payments on those Senior 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 the Company elects to make interest payments by check mailed to the Holders at their address set forth in the register of Holders. PAYING AGENT AND REGISTRAR FOR THE SENIOR NOTES The Trustees will initially act as Paying Agent and Registrar. The Company may change the Paying Agent or Registrar without prior notice to the Holders of the Senior Notes, and the Company or any of its Subsidiaries may act as Paying Agent or Registrar. TRANSFER AND EXCHANGE A Holder may transfer or exchange Senior 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 the Company may require a Holder to pay any taxes and fees required by law or permitted by the Indenture. The registered Holder of a Senior Note will be treated as the owner of it for all purposes. PAYMENTS FOR CONSENT The Company 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 Senior Notes for or as an inducement to any consent, waiver or amendment of any of the terms or provisions of the Indenture or the Senior Notes unless such consideration is offered to be paid and is paid to all Holders of the Senior 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 Commission, so long as any Senior Notes are outstanding, the Company shall file with the Commission (if permitted) all of the reports and other information as it would be required to file with the Commission by Sections 13(a) and 15(d) under the Securities Exchange Act of 1934, as amended, as if it were subject thereto. The Company shall supply the Trustees and each Holder of Senior Notes, or shall supply to the Trustees for forwarding to each Holder of Senior 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 Senior 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 Senior Notes; (2) default in payment when due of the principal of or premium, if any, on the Senior Notes; (3) failure by the Company or any of its Subsidiaries to make any payment required to be made under the provisions described 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;" 36

41 (4) failure by the Company 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 the Company by the Trustees or the Holders of at least 25% in principal amount of then outstanding Senior 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 the Company or any of its Restricted Subsidiaries (or the payment of which is guaranteed by the Company 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; (6) failure by the Company 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 the Company 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 the Company, any Subsidiary that is a Significant Subsidiary or any group of Subsidiaries that, taken together, would constitute a Significant Subsidiary, all outstanding Senior 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 Senior Notes may declare all the Senior Notes to be due and payable immediately. Holders of the Senior Notes may not enforce their respective Indentures or the Senior Notes except as provided in the Indenture. Subject to certain limitations, Holders of a majority in principal amount of the then outstanding Senior Notes may direct a Trustee in its exercise of any trust or power. A Trustee may withhold from Holders of the Senior 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 Senior Notes then outstanding by notice to a Trustee may on behalf of the Holders of all of the Senior 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 Senior Notes. The Company is required to deliver to the Trustees annually a statement regarding compliance with the Indenture. Upon becoming aware of any Default or Event of Default, the Company is required to deliver to the Trustees 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 the Company or any Guarantor, as such, shall have any liability for any obligations of the Company or the Guarantors under the Senior Notes, the Indenture, the Subsidiary Guarantees or for any claim based on, in respect of, or by reason of, such obligations or their creation. Each Holder of Senior Notes by accepting a Senior Note waives and releases all such liability. The 37

42 waiver and release are part of the consideration for issuance of the Senior Notes. The waiver may not be effective to waive liabilities under the federal securities laws. LEGAL DEFEASANCE AND COVENANT DEFEASANCE The Company may, at its option and at any time, elect to have all of its obligations discharged with respect to the outstanding Senior 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 Senior Notes to receive payments in respect of the principal of, premium, if any, and interest and Liquidated Damages on such Senior Notes when such payments are due from the trust referred to below; (2) the Company's obligations with respect to the Senior Notes concerning issuing temporary Senior Notes, registration of Senior Notes, mutilated, destroyed, lost or stolen Senior 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 the Company's obligations in connection therewith; and (4) the Legal Defeasance provisions of the Indenture. In addition, the Company may, at its option and at any time, elect to have the Obligations of the Company 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 Senior Notes. In the event Covenant Defeasance occurs, certain events (other than non-payment, bankruptcy, receivership, rehabilitation and insolvency events) described under "Events of Default" will no longer constitute an Event of Default with respect to the Senior Notes. In order to exercise either Legal Defeasance or Covenant Defeasance: (1) the Company must irrevocably deposit with the Trustee, in trust, for the benefit of the Holders of the Senior Notes, cash in U.S. dollars, non-callable 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 Senior Notes on the stated maturity or on the applicable redemption date, as the case may be, and the Company must specify whether the Senior Notes are being defeased to maturity or to a particular redemption date; (2) in the case of Legal Defeasance, the Company shall have delivered to the Trustee an Opinion of Counsel reasonably acceptable to the Trustee confirming that (a) the Company 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 Senior 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, the Company shall have delivered to the Trustee an Opinion of Counsel reasonably acceptable to the Trustee confirming that the Holders of the outstanding Senior 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 38

43 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) or 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 the Company or any of its Restricted Subsidiaries is a party or by which the Company or any of its Restricted Subsidiaries is bound; (6) the Company 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) the Company must deliver to the Trustee an Officers' Certificate stating that the deposit was not made by the Company with the intent of preferring the Holders of Senior Notes over the other creditors of the Company with the intent of defeating, hindering, delaying or defrauding creditors of the Company or others; (8) the Company must deliver to the Trustee an Officers' 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) release any Guarantor from any of its Obligations under its Guarantee of the Senior Notes or the Indenture, except in accordance with the terms of the Indenture. 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 Senior 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 Senior Notes. Without the consent of each Holder affected, an amendment or waiver may not (with respect to any Notes held by a non-consenting Holder): (1) reduce the principal amount of Senior Notes whose Holders must consent to an amendment, supplement or waiver; (2) reduce the principal of or change the fixed maturity of any Senior Note or alter the provisions with respect to the redemption of the Senior 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 Senior Note; (4) waive a Default or Event of Default in the payment of principal of or premium, if any, or interest on the Senior Notes (except a rescission of acceleration of the Senior Notes by the Holders of at least a majority in aggregate principal amount of the Senior Notes and a waiver of the payment default that resulted from such acceleration); (5) make any Senior Note payable in money other than that stated in the Senior Notes; 39

44 (6) make any change in the provisions of the Indenture relating to waivers of past Defaults or the rights of Holders of Senior Notes to receive payments of principal of or premium, if any, or interest on the Senior Notes; (7) waive a payment required by one of the covenants described above under the caption "-- Repurchase at the Option of Holders;" or (8) make any change in the preceding amendment and waiver provisions. Notwithstanding the preceding, without the consent of any Holder of Senior Notes, the Company and the Trustee may amend or supplement the Indenture or the Senior Notes: (1) to cure any ambiguity, defect or inconsistency; (2) to provide for uncertificated Senior Notes in addition to or in place of certificated Senior Notes; (3) to provide for the assumption of the Company's obligations to Holders of Senior Notes in the case of a merger or consolidation or sale of all or substantially all of the Company's assets; (4) to make any change that would provide any additional rights or benefits to the Holders of Senior Notes or that does not adversely affect the legal rights under the Indenture of any such Senior Holder; or (5) to comply with requirements of the Commission in order to effect or maintain the qualification of the Indenture under the Trust Indenture Act. CONCERNING THE TRUSTEE If a Trustee becomes a creditor of the Company or any Guarantor, the Indenture limit 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; however, if it acquires any conflicting interest it must eliminate such conflict within 90 days, apply to the Commission for permission to continue or resign. The Holders of a majority in principal amount of the then outstanding Senior Notes will have the right to direct the time, method and place of conducting any proceeding for exercising any remedy available to a Trustee, subject to certain exceptions. The Indenture provides that in case an Event of Default shall occur and be continuing, the Trustees will be required, in the exercise of their power, to use the degree of care of a prudent man in the conduct of his own affairs. Subject to such provisions, the Trustees will be under no obligation to exercise any of their rights or powers under the Indenture at the request of any Holder of Senior Notes, unless such Holder shall have offered to the Trustees security and indemnity satisfactory to it against any loss, liability or expense. ADDITIONAL INFORMATION Anyone who receives this prospectus may obtain a copy of the registration statement and the exhibits to the registration statement, which include the Indenture and Registration Rights Agreement, without charge by writing to Amkor Technology, Inc., 1345 Enterprise Drive, West Chester, Pennsylvania 19380, Attention: Kevin Heron, Esq. GOVERNING LAW The Indenture provides that they and the Senior Notes will be governed by, and construed in accordance with, the laws of the State of New York without giving effect to applicable principles of conflicts of laws to the extent that the application of the law of another jurisdiction would be required thereby. 40

45 ENFORCEABILITY OF JUDGMENTS Since most of the assets of the Company are outside the United States, any judgments obtained in the United States against the Company, including judgments with respect to the payment of principal, premium, interest, Liquidated Damages, Change of Control Payment, offer price, redemption price or other amounts payable under the Senior Notes, may be not collectible within the United States. The Company has been informed by its Korean counsel, Kim & Chang, that the laws of the Republic of Korea permit an action to be brought in a court of competent jurisdiction in the Republic of Korea (a "Korean Court") on any final and conclusive judgment in personam of any federal or state court located in the Borough of Manhattan in The City of New York ("New York Court") that is not impeachable as void or voidable under the internal laws of the State of New York for a sum certain in respect of the enforcement of the Indentures or the Notes provided that (i) such judgment was final, conclusive and non-appelable and was rendered by the New York Court having valid jurisdiction, (ii) the defendant against whom such judgment was awarded received service of process in conformity with the laws of the jurisdiction of the New York Court rendering judgment otherwise than by publication or responded to the action without having been served with process, (iii) recognition and enforcement of such judgment is not contrary to the public policy of Korea, and (iv) judgments of the courts of Korea would be similarly recognized and enforced in the courts of the State of New York which had given such judgement. The Company has been informed by its Philippines counsel, Ortega, Del Castillo, Bacorro, Odulio, Calma & Carbonell Law Offices, that the Rules of Court of the Republic of the Philippines and jurisprudence related thereto permit an action to be brought in a court of competent jurisdiction in the Republic of the Philippines (a "Philippines Court") on any final and conclusive judgment in personam of any New York Court that is not impeachable as void or voidable under the internal laws of the State of New York for a sum certain in respect of the enforcement of the Indenture or the Senior Notes if (i) the court rendering such judgment had jurisdiction over the subject matter and the judgment debtor, as recognized by the Philippines Court (and submission by the Company in the Indentures to the non-exclusive jurisdiction of the New York Court will be sufficient for that purpose), (ii) such judgment was not obtained by want of jurisdiction or lack of notice to any affected party or collusion or fraud or clear mistake of law or fact and the enforcement thereof would not be inconsistent with public policy, as these terms are interpreted by a Philippines Court, (iii) the enforcement of such judgment does not constitute, directly or indirectly, the enforcement of such foreign revenue, expropriatory or penal laws and (iv) the action to enforce such judgment is commenced within the applicable limitation period. Provided conditions (i) through (iv) as set forth above are satisfied, the Company has been advised by Ortega, Del Castillo, Bacorro, Odulio, Calma & Carbonell that it knows of no reason, based upon public policy under the federal laws of the Republic of the Philippines for avoiding recognition of a judgment of a New York Court to enforce the Indenture or the Senior Notes. BOOK-ENTRY, DELIVERY AND FORM AND TRANSFER The old Senior Notes were initially in the form of one or more registered global notes without interest coupons (collectively, the "old Global Notes"). Upon issuance, the old Global Notes were deposited with the Trustee, as custodian for The Depository Trust Company ("DTC"), in New York, New York, and registered in the name of DTC or its nominee for credit to the accounts of DTC's Direct Participants and Indirect Participants (as defined below). Beneficial interests in all old Global Notes and all old Certificated Notes (as defined below), if any, will be subject to certain restrictions on transfer and will bear a restrictive legend. See "Risk Factors -- Consequences of Not Tendering Old Senior Notes." In addition, transfer of beneficial interests in any Global Notes will be subject to the applicable rules and procedures of DTC and its Direct or Indirect Participants, which may change from time to time. 41

46 The new Senior Notes initially will be in the form of one or more registered global notes without interest coupons (collectively, the "new Global Notes"). Upon issuance, the new Global Notes will be deposited with the Trustee as, custodian for DTC, in New York, New York, and registered in the name of DTC or its nominee for credit to the accounts of DTC's Direct Participants and Indirect Participants. Transfer of beneficial interests in new Global Notes will be subject to the applicable rules and procedures of DTC and its Direct or Indirect Participants, which may change from time to time. The old and new Global Notes may be transferred, in whole and not in part, only to another nominee of DTC or to a successor of DTC or its nominee in certain limited circumstances. Beneficial interests in the old and new Global Notes may be exchanged for Senior Notes in certificated form in certain limited circumstances. See "-- Transfer of Interests in Global Notes for Certificated Notes." Initially, the Trustee will act as Paying Agent and Registrar. The Senior Notes may be presented for registration of transfer and exchange at the offices of the Registrar. Depositary Procedures DTC has advised the Company that DTC is a limited-purpose trust company created to hold securities for its participating organizations (collectively, the "Direct Participants") and to facilitate the clearance and settlement of transactions in those securities between Direct Participants through electronic book-entry changes in accounts of Participants. The Direct Participants include securities brokers and dealers, banks, trust companies, clearing corporations and certain other organizations. Access to DTC's system is also available to other entities that clear through or maintain a direct or indirect, custodial relationship with a Direct Participant (collectively, the "Indirect Participants"). DTC has advised the Company that, pursuant to DTC's procedures, DTC will maintain records of the ownership interests of Direct Participants in the old and new Global Notes and the transfer of ownership interests by and between Direct Participants. DTC will not maintain records of the ownership interests of, or the transfer of ownership interests by and between, Indirect Participants or other owners of beneficial interests in the old and new Global Notes. Direct Participants and Indirect Participants must maintain their own records of the ownership interests of, and the transfer of ownership interests by and between, Indirect Participants and other owners of beneficial interests in the old and new Global Notes. Investors in the old and new Global Notes may hold their interests therein directly through DTC if they are Direct Participants in DTC or indirectly through organizations that are Direct Participants in DTC. All ownership interests in any old or new Global Notes may be subject to the procedures and requirements of DTC. The laws of some states in the United States require that certain persons take physical delivery in definitive, certificated form, of securities that they own. This may limit or curtail the ability to transfer beneficial interests in an old or new Global Note to such persons. Because DTC can act only on behalf of Direct Participants, which in turn act on behalf of Indirect Participants and others, the ability of a person having a beneficial interest in an old or new Global Note to pledge such interest to persons or entities that are not Direct Participants in DTC, or to otherwise take actions in respect of such interests, may be affected by the lack of physical certificates evidencing such interests. For certain other restrictions on the transferability of the Senior Notes see "-- Transfers of Interests in Global Notes for Certificated Notes." EXCEPT AS DESCRIBED IN "-- TRANSFERS OF INTERESTS IN GLOBAL NOTES FOR CERTIFICATED NOTES", OWNERS OF BENEFICIAL INTERESTS IN THE OLD AND NEW GLOBAL NOTES WILL NOT HAVE SENIOR NOTES REGISTERED IN THEIR NAMES, WILL NOT RECEIVE PHYSICAL DELIVERY OF SENIOR NOTES IN CERTIFICATED FORM AND WILL NOT BE CONSIDERED THE REGISTERED OWNERS OR HOLDERS THEREOF UNDER THE INDENTURE FOR ANY PURPOSE OTHER THAN WITH RESPECT TO THE PAYMENT OF LIQUIDATED DAMAGES. Under the terms of the Indenture, the Company and the Trustees will treat the persons in whose names the Senior Notes are registered (including Senior Notes represented by the old and new Global Notes) as the 42

47 owners thereof for the purpose of receiving payments and for any and all other purposes whatsoever. Payments in respect of the principal, premium, Liquidated Damages, if any, and interest on old and new Global Notes registered in the name of DTC or its nominee will be payable by the Trustees to DTC or its nominee as the registered holder under the Indenture. Consequently, neither the Company, the Trustees nor any agent of the Company or the Trustees has or will have any responsibility or liability for (i) any aspect of DTC's records or any Direct Participant's or Indirect Participant's records relating to or payments made on account of beneficial ownership interests in the Global Notes or for maintaining, supervising or reviewing any of DTC's records or any Direct Participant's or Indirect Participant's records relating to the beneficial ownership interests in any Global Note or (ii) any other matter relating to the actions and practices of DTC or any of its Direct Participants or Indirect Participants. DTC has advised the Company that its current payment practice (for payments of principal, interest and the like) with respect to securities such as the Senior Notes is to credit the accounts of the relevant Direct Participants with such payment on the payment date in amounts proportionate to such Direct Participant's respective ownership interests in the old and new Global Notes as shown on DTC's records. Payments by Direct Participants and Indirect Participants to the beneficial owners of the Senior Notes will be governed by standing instructions and customary practices between them and will not be the responsibility of DTC, the Trustee or the Company. Neither the Company nor the Trustees will be liable for any delay by DTC or its Direct Participants or Indirect Participants in identifying the beneficial owners of the Senior Notes, and the Company and the Trustees may conclusively rely on and will be protected in relying on instructions from DTC or its nominee as the registered owner of the Senior Notes for all purposes. The old and new Global Notes will trade in DTC's Same-Day Funds Settlement System and, therefore, transfers between Direct Participants in DTC will be effected in accordance with DTC's procedures, and will be settled in immediately available funds. Transfers between Indirect Participants who hold an interest through a Direct Participant will be effected in accordance with the procedures of such Direct Participant but generally will settle in immediately available funds. DTC has advised the Company that it will take any action permitted to be taken by a holder of Senior Notes only at the direction of one or more Direct Participants to whose account interests in the old and new Global Notes are credited and only in respect of such portion of the aggregate principal amount of the Notes to which such Direct Participant or Direct Participants has or have given direction. However, if there is an Event of Default under the Notes, DTC reserves the right to exchange old and new Global Notes (without the direction of one or more of its Direct Participants) for Senior Notes in certificated form, and to distribute such certificated forms of Senior Notes to its Direct Participants. See "-- Transfers of Interests in Global Notes for Certificated Notes." Although DTC has agreed to the foregoing procedures to facilitate transfers of interests in the old and new Global Notes among Direct Participants, it is under no obligation to perform or to continue to perform such procedures, and such procedures may be discontinued at any time. Neither the Company nor the Trustees shall have any responsibility for the performance by DTC or its Direct and Indirect Participants of their respective obligations under the rules and procedures governing any of their operations. The information in this section concerning DTC and its book-entry systems has been obtained from sources that the Company believes to be reliable, but the Company takes no responsibility for the accuracy thereof. Transfers of Interests in Global Notes for Certificated Notes An entire old or new Global Note may be exchanged for definitive Senior Notes in registered, certificated form without interest coupons ("Certificated Notes") if (i) DTC (x) notifies the Company that it is unwilling or unable to continue as depositary for the old and new Global Notes and the Company thereupon fails to appoint a successor depositary within 90 days or (y) has ceased to be a clearing agency registered under the 43

48 Exchange Act, (ii) the Company, at its option, notifies the appropriate Trustee in writing that it elects to cause the issuance of Certificated Notes or (iii) there shall have occurred and be continuing a Default or an Event of Default with respect to the Notes. In any such case, the Company will notify the appropriate Trustee in writing that, upon surrender by the Direct and Indirect Participants of their interest in such Global Note, Certificated Notes will be issued to each person that such Direct and Indirect Participants and the DTC identify as being the beneficial owner of the related Senior Notes. Beneficial interests in old and new Global Notes held by any Direct or Indirect Participant may be exchanged for Certificated Notes upon request to DTC, by such Direct Participant (for itself or on behalf of an Indirect Participant), to the appropriate Trustee in accordance with customary DTC procedures. Certificated Notes delivered in exchange for any beneficial interest in any old or new Global Note will be registered in the names, and issued in any approved denominations, requested by DTC on behalf of such Direct or Indirect Participants (in accordance with DTC's customary procedures). Neither the Company nor the Trustees will be liable for any delay by the holder of any old or new Global Note or DTC in identifying the beneficial owners of Senior Notes, and the Company and the Trustees may conclusively rely on, and will be protected in relying on, instructions from the holder of an old or new Global Note or DTC for all purposes. Same Day Settlement and Payment The Indenture will require that payments in respect of the Senior Notes represented by the old and new Global Notes (including principal, premium, if any, and interest and Liquidated Damages, if any) be made by wire transfer of immediately available same day funds to the accounts specified by the holder of interests in such old or new Global Note. With respect to Certificated Notes, the Company will make all payments of principal, premium, Liquidated Damages, if any, and interest by wire transfer of immediately available same day funds to the accounts specified by the holders thereof or, if no such account is specified, by mailing a check to each such holder's registered address. The Company expects that secondary trading in the Certificated Notes will also be settled in immediately available funds. REGISTRATION RIGHTS; LIQUIDATED DAMAGES The Company and the Initial Purchasers entered into the Registration Rights Agreement on February 20, 2001. Pursuant to the Registration Rights Agreement, the Company agreed to use commercially reasonable efforts to file with the Commission the Exchange Offer Registration Statement on the appropriate form under the Securities Act with respect to the Exchange Notes. The registration statement of which this prospectus forms a part constitutes such Exchange Offer Registration Statement. Pursuant to the Exchange Offer Registration Statement of which this prospectus forms a part, the Company is offering to the Holders of Transfer Restricted Securities who are able to make certain representations the opportunity to exchange their Transfer Restricted Securities for new Senior Notes. As described above, the terms of new Senior Notes will be identical in all material respects to those of the old Senior Notes, except that the new Senior Notes will not contain terms with respect to transfer restrictions, registration rights or payment of Liquidated Damages. See "Additional Terms of New Senior Notes." 44

49 If (i) the Exchange Offer is not permitted by applicable law or Commission policy or (ii) any Holder of Senior Notes which are Transfer Restricted Securities notifies the Company prior to the 20th business day following the consummation of the Exchange Offer that (a) it is prohibited by law or Commission 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 Senior Notes acquired directly from the Company or any of the Company's affiliates, the Company will file with the Commission a Shelf Registration Statement to register for public resale the Transfer Restricted Securities held by any such Holder who provides the Company with certain information for inclusion in the Shelf Registration Statement. For the purposes of the Registration Rights Agreement, "Transfer Restricted Securities" means each Senior Note until: (1) the date on which such Senior 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 Senior 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 Senior 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 Senior Note is distributed to the public pursuant to Rule 144 under the Securities Act. The Registration Rights Agreement provides that: (1) the Company will use commercially reasonable efforts to file an Exchange Offer Registration Statement with the Commission on or prior to the 120th day after the Closing Date; (2) the Company will use commercially reasonable efforts to have the Exchange Offer Registration Statement declared effective by the Commission on or prior to the 210th day after the Closing Date; (3) unless the Exchange Offer would not be permitted by applicable law or Commission policy, the Company 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 Commission, Exchange Notes in exchange for all Senior Notes tendered prior thereto in the Exchange Offer; and (4) if obligated to file the Shelf Registration Statement, the Company will use commercially reasonable efforts to file the Shelf Registration Statement with the Commission on or prior to 60 days after such filing obligation arises and to cause the Shelf Registration to be declared effective by the Commission on or prior to 120 days after such obligation arises. If: (1) the Company fails 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 statements is not declared effective by the Commission on or prior to the date specified for such effectiveness (the "Effectiveness Target Date"); or 45

50 (3) the Company fails 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 the Company will pay Liquidated Damages to each Holder of Senior 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 the Company on each Damages Payment Date to the Global Note Holder by wire transfer of immediately available funds or by federal funds check and to Holders of Certificated Notes 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 Senior Notes will be required to make certain representations to the Company (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 Senior Notes included in the Shelf Registration Statement and benefit from the provisions regarding Liquidated Damages set forth above. Holders of Senior Notes will also be required to suspend their use of the prospectus included in the Shelf Registration Statement under certain circumstances upon receipt of written notice to that effect from the Company. By acquiring Transfer Restricted Securities, a Holder will be deemed to have agreed to indemnify the Company against certain losses arising out of information furnished by such Holder in writing for inclusion in any Shelf Registration Statement. CONSENT TO JURISDICTION AND SERVICE The Indentures provide that the Company will irrevocably appoint CT Corporation System as its agent for service of process in any suit, action, or proceeding with respect to the Indentures or the Notes and for actions brought under federal or state securities laws in any federal or state court located in the Borough of Manhattan in The City of New York, and submits to such jurisdiction.

Notwithstanding the preceding, the provision for taxes based on the income or profits of, and the depreciation and amortization and other non-cash charges of, a Restricted Subsidiary of the Company shall be added to Consolidated Net Income to compute Consolidated Cash Flow of the Company only to the extent that a corresponding amount would be permitted at the date of determination to be dividended to the Company by such Restricted Subsidiary without prior approval (that has not been obtained), pursuant to the terms of its charter and all agreements, instruments, judgments, decrees, orders, statutes, rules and governmental regulations applicable to that Subsidiary or its stockholders. "Consolidated Interest Expense" means, with respect to any Person for any period, the sum, without duplication, of: (1) the consolidated interest expense of such Person and its Restricted Subsidiaries for such period, whether paid or accrued, including, without limitation, amortization of debt issuance costs and original issue discount, non-cash interest payments, the interest component of any deferred payment obligations, the interest component of all payments associated with Capital Lease Obligations, imputed interest with respect to Attributable Debt, commissions, discounts and other fees and charges incurred in respect of letter of credit or bankers' acceptance financings, and net payments, if any, pursuant to Hedging Obligations; plus (2) the consolidated interest of such Person and its Restricted Subsidiaries that was capitalized during such period; plus (3) interest actually paid by the Company or any Restricted Subsidiary under any Guarantee of Indebtedness of another Person; plus (4) the product of all dividend payments, whether or not in cash, on any series of preferred stock of such Person or any of its Restricted Subsidiaries, other than dividend payments on Equity Interests payable solely in Equity Interests of the Company (other than Disqualified Stock) or to the Company or a Restricted Subsidiary of the Company. "Consolidated Interest Expense Coverage Ratio" means with respect to any specified Person for any period, the ratio of the Consolidated Cash Flow of such Person and its Restricted Subsidiaries for such period to the Consolidated Interest Expense of such Person for such period.

In addition, for purposes of calculating the Consolidated Interest Expense Coverage Ratio: (1) acquisitions that have been made by the specified Person or any of its Restricted Subsidiaries, including through mergers or consolidations and including any related financing transactions, during the four-quarter reference period or subsequent to such reference period and on or prior to the Calculation Date shall be deemed to have occurred on the first day of the four-quarter reference period and Consolidated Cash Flow for such reference period shall be calculated without giving effect to clause (3) of the proviso set forth in the definition of Consolidated Net Income; 50

55 (2) the Consolidated Cash Flow attributable to discontinued operations, as determined in accordance with GAAP, and operations or businesses disposed of prior to the Calculation Date, shall be excluded; and (3) the Consolidated Interest Expense attributable to discontinued operations, as determined in accordance with GAAP, and operations or businesses disposed of prior to the Calculation Date, shall be excluded, but only to the extent that the obligations giving rise to such Consolidated Interest Expense will not be obligations of the specified Person or any of its Restricted Subsidiaries following the Calculation Date.

We cannot assure you that the Internal Revenue Service will not successfully challenge one or more of the tax consequences described herein, and we have not obtained, nor do we intend to obtain, a ruling from the IRS or an opinion of counsel with respect to the U.S. federal income tax consequences of acquiring or holding new Senior Notes. This discussion does not purport to deal with all aspects of U.S. federal income taxation that may be relevant to a particular holder in light of the holder's circumstances (for example, persons subject to the alternative minimum tax provisions of the Code). Also, it is not intended to be wholly applicable to all categories of investors, such as foreign persons, dealers in securities, banks, insurance companies, tax-exempt organizations, and persons holding new Senior Notes as part of a hedging or conversion transaction or straddle or persons deemed to sell new Senior Notes under the constructive sale provisions of the Code, some of which may be subject to special rules. The discussion below is premised upon the assumption that the new Senior Notes and old Senior Notes are held (or would be held if acquired) as capital assets within the meaning of Section 1221 of the Code. The discussion also does not discuss any aspect of state, local or foreign law. EACH HOLDER OR PROSPECTIVE HOLDER OF NEW SENIOR NOTES IS STRONGLY URGED TO CONSULT ITS OWN TAX ADVISOR WITH RESPECT TO ITS PARTICULAR TAX SITUATION INCLUDING THE TAX EFFECT OF ANY STATE, LOCAL, FOREIGN, OR OTHER TAX LAWS AND POSSIBLE CHANGES IN THE TAX LAWS. EXCHANGE OF SENIOR NOTES The exchange of old Senior Notes for new Senior Notes pursuant to the exchange offers should not be a taxable exchange for U.S. federal income tax purposes. Accordingly, a holder should have the same adjusted issue price, adjusted basis and holding period in the new Senior Notes as it had in the old Senior Notes immediately before the exchange. PLAN OF DISTRIBUTION Each broker-dealer that holds any old Senior Notes acquired for its own account as a result of market-making or other trading activities (a "Participating Broker-Dealer") may exchange old Senior Notes for new Senior Notes. Each Participating Broker-Dealer receiving new Senior Notes for its own account in connection with the exchange offer must acknowledge that it will deliver a prospectus in connection with any resale of such new Senior Notes. Participating Broker-Dealers may use this prospectus during the period referred to below in connection with resales of the new Notes received in exchange for old Senior Notes if such old Senior Notes were acquired by such Participating Broker-Dealers for their own accounts. We agreed that this prospectus may be used by a Participating Broker-Dealer in connection with resales of such new Senior Notes for a period ending 180 days after the effective date of the registration statement (subject to extension under certain limited circumstances described herein) or, if earlier, when all such new Senior Notes have been disposed of by such Participating Broker-Dealer. See "The Exchange Offer -- Terms of the Exchange Offer." We will not receive any cash proceeds from the issuance of the new Senior Notes offered by this prospectus. New Senior Notes received by Participating Broker-Dealers for their own accounts in connection with 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 new Senior Notes or a combination of 62

67 such methods of resale, at market prices prevailing at the time of resale, at prices related to such prevailing market prices or at negotiated prices. Any resale of the new Senior Notes 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 broker-dealer and/or the purchasers of any new Senior Notes. Any Participating Broker-Dealer that resells new Senior Notes that were received by it for its own account in the exchange offers and any broker or dealer that participates in a distribution of such new Senior Notes may be deemed to be an "underwriter" within the meaning of the Securities Act. Any profit on any such resale of new Senior 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, a Participating Broker-Dealer will not be deemed to admit that it is an "underwriter" within the meaning of the Securities Act.
