1. Interim Financial Statements

     Basis of Presentation. The condensed consolidated financial statements and related disclosures as of March 31, 2005 and for the three months ended March 31, 2005 and 2004 are unaudited, pursuant to the rules and regulations of the Securities and Exchange Commission. Certain information and footnote disclosures normally included in financial statements prepared in accordance with generally accepted accounting principles have been condensed or omitted pursuant to such rules and regulations. In our opinion, these financial statements include all adjustments (consisting only of normal recurring adjustments) necessary for the fair statement of the results for the interim periods. These financial statements should be read in conjunction with our latest Annual Report as of December 31, 2004 filed on Form 10-K/A with the Securities and Exchange Commission.

     The results of operations for the three months ended March 31, 2005 are not necessarily indicative of the results to be expected for the full year. Certain previously reported amounts have been reclassified to conform to the current period presentation.

     2005 restatement. We are filing this amendment on Form 10-Q/A to our Quarterly Report on Form 10-Q to restate our condensed consolidated financial statements for the three months ended March 31, 2005. In connection with finalizing the restatement of our previously filed financial statements for each of the three years in the period ended December 31, 2004, as included in our amended Annual Report on Form 10-K/A filed on June 6, 2005, we have revised the amount of unpaid capital expenditures utilized in preparing our condensed consolidated statement of cash flows for the three months ended March 31, 2005 that was included in our Quarterly Report on Form 10-Q filed on May 16, 2005. In conjunction with the restatement of our Annual Report, as described above, we restated our condensed consolidated financial statements included in our Quarterly Reports on Form 10-Q for the quarters ended March 31, June 30, and September 30 of 2004. We filed amendments on Form 10-Q/A to these Quarterly Reports on June 6, 2005.

     The following table sets forth the effects of the restatement on certain line items within our previously reported condensed consolidated statement of cash flows for the three months ended March 31, 2005:

     Use of Estimates. The condensed consolidated financial statements have been prepared in conformity with accounting principles generally accepted in the United States of America (“U.S.”), using management’s best estimates and judgments where appropriate. These estimates and judgments affect the reported amounts of assets and liabilities and disclosure of the contingent assets and liabilities at the date of the financial statements. The estimates and judgments will also affect the reported amounts for certain revenues and expenses during the reporting period. Actual results could differ materially from these estimates and judgments.

     Income Taxes. For the three months ended March 31, 2005, income tax expense was $1.2 million, reflecting an effective tax rate of 1.0%. For the three months ended March 31, 2004, income tax expense was $1.4 million, reflecting an effective tax rate of 11.3%. Our effective tax rates for the three months ended March 31, 2005 and March 31, 2004 differ significantly from the U.S. statutory tax rate of 35% primarily due to tax losses in the U.S. and certain foreign jurisdictions for which we can not take a benefit. The tax expense for the three months ended March 31, 2005 and March 31, 2004 related primarily to foreign withholding taxes and income taxes at our profitable foreign locations.

     We operate in and file income tax returns in various U.S. and foreign jurisdictions which are subject to examination by tax authorities. For our larger operations, our tax returns have been examined through 1998 in the Philippines and the U.S., through 2000 in Taiwan, and through 2002 in Japan. The tax returns for open years in all jurisdictions in which we do business are subject to changes upon examination. During 2003, the Internal Revenue Service commenced an examination

6

related to years 2000 and 2001. In February 2005, we verbally agreed to a settlement in principle with the IRS for these years. As a component of the settlement, we agreed to make certain income adjustments to our U.S. tax returns in the years 2000 through 2003 for local attribution of income resulting from significant inter-company transactions, including ownership and use of intellectual property, in various U.S. and foreign jurisdictions. These adjustments would effectively lower our U.S. net operating loss carry-forwards at December 31, 2004 by $52.7 million. This settlement agreement is not final until review and approval by the Congressional Joint Committee on Taxation, the timing of which is uncertain. We believe that we have estimated and provided adequate accruals for the additional taxes and interest expense that will result from these adjustments. Our estimated tax liability is subject to change as examinations of specific tax years are completed in the respective jurisdictions. We believe that any additional taxes or related interest over the amounts accrued will not have a material effect on our financial condition or results of operations, nor do we expect that examinations to be completed in the near term would have a material favorable impact. In addition, changes in the mix of income from our foreign subsidiaries, expiration of tax holidays and changes in tax laws or regulations could result in increased effective tax rates in the future.

     Recent Accounting Pronouncements. In March 2004, the Emerging Issues Task Force (“EITF”) reached a consensus on Issue 03-01, The Meaning of Other-Than-Temporary Impairment and Its Application to Certain Investments. EITF 03-01 provides guidance on other-than-temporary impairment models for marketable debt and equity securities accounted for under SFAS No. 115, Accounting for Certain Investments in Debt and Equity Securities, and SFAS No. 124, Accounting for Certain Investments Held by Not-for-Profit Organizations, and non-marketable equity securities accounted for under the cost method. The EITF developed a basic three-step model to evaluate whether an investment is other-than temporarily impaired. On September 30, 2004, the FASB approved the issuance of the FASB Staff Position (“FSP”) EITF 03-01-1, which delays the effective date until additional guidance is issued for the application of the recognition and measurement provisions of EITF 03-01 to investments in securities that are impaired. We will apply the guidance in EITF 03-01 to our investments when it becomes effective. See Note 6 for the investments held by us which would be effected by EITF 03-01.

     In December 2004, the FASB issued Statement of Financial Accounting Standards (“SFAS”) No. 123R, Share-Based Payment. SFAS No. 123R is a revision of SFAS No. 123, Accounting for Stock Based Compensation and supersedes APB 25. Among other items, SFAS No. 123R eliminates the use of APB 25 and the intrinsic value method of accounting and requires companies to recognize the cost of employee services received in exchange for awards of equity instruments, based on the grant date fair value of those awards, in the financial statements. On April 14, 2005, the Securities and Exchange Commission (“SEC”) amended the effective date of SFAS No. 123R to January 1, 2006, for calendar year companies. We intend to adopt this statement on the new effective date.

     We currently utilize a standard option pricing model (Black-Scholes) to measure the fair value of stock options granted to employees. While SFAS No. 123R permits entities to continue to use such a model, the standard also permits the use of a “lattice” model. We have not yet determined which model we will use to measure the fair value of employee stock options upon the adoption of SFAS No. 123R.

     SFAS No. 123R also requires the benefits associated with the tax deductions in excess of recognized compensation cost be reported as a financing cash flow, rather than as an operating cash flow as required under current literature. This requirement will reduce net operating cash flows and increase net financing cash flows in periods after the effective date. These future amounts cannot be estimated because they depend on when the employees exercise stock options, among other things.

     We are currently reviewing the effect SFAS No. 123R will have on our financial statements; however, we believe the impact to our net income (loss) will be determined by the number of options that we grant in the future. In August 2004 we accelerated the vesting of all outstanding employee stock options, thereby eliminating charges to our future statements of operations related to these stock options. In addition to eliminating future compensation charges upon the adoption of SFAS No. 123 R, we also undertook the acceleration to enhance employee morale and to help retain high-potential individuals in the face of a downturn in industry conditions.

     Stock Compensation. We apply Accounting Principles Board (APB) Opinion No. 25, Accounting for Stock Issued to Employees, and related Interpretations, to our stock option plans. No compensation expense has been recognized for our employee stock options that have been granted. If compensation costs for our stock option plans had been determined using the fair value method of accounting as set forth in SFAS No. 123, Accounting for Stock-Based Compensation, our reported net income (loss) and per share amounts would have been decreased (increased).

     The following table illustrates the effect on net income (loss) and per share amounts if the fair value based method had been applied to all outstanding and unvested awards in each period.

7

     In order to calculate the fair value of stock options at date of grant, we used the Black-Scholes option pricing model. The following assumptions were used to calculate weighted average fair values of the options granted:

2. Comprehensive Income (Loss)

     The following table summarizes comprehensive income (loss) for the periods presented:

3. Inventories

     Inventories consist of the following:

     The following table reconciles our activity related to property, plant and equipment payments as presented on the statement of cash flows to property, plant and equipment additions as reflected in the balance sheet:

5. Goodwill and Intangibles

     Our goodwill balance relates to our packaging services reporting unit. The change in the carrying value of goodwill is as follows:

     Intangibles as of March 31, 2005 consist of the following:

     Intangibles as of December 31, 2004 consist of the following:

     Amortization expense was $2.4 million and $1.4 million for the three months ended March 31, 2005 and 2004, respectively.

     Based on the amortizing assets recognized in our balance sheet at March 31, 2005, amortization expense for each of the next five fiscal years is estimated as follows:

6. Investments

     Investments consist of the following:

7. Accrued Expenses

     Accrued expenses consist of the following:

8. Corporate Relocation Expenses

     During the third quarter of 2004, we commenced efforts to relocate certain corporate functions from our West Chester, Pennsylvania location to our Chandler, Arizona location. In connection with these efforts, we expect to pay $1.2 million in severance and related costs. Of this $1.2 million, we recorded a charge of $0.9 million to selling, general and administrative expenses during 2004, and we charged the remaining $0.3 million to selling, general and administrative expenses during the first quarter of 2005. For the three months ended March 31, 2005, we paid out $0.8 million in severance benefits. As of March 31, 2005 we have $0.4 million accrued in severance and related costs which we expect to be paid in the second quarter of 2005.

9. Debt

     The major components of debt consist of the following:

     We have a significant amount of indebtedness and expect this will continue for the foreseeable future. Our indebtedness requires us to dedicate a substantial portion of our cash flow from operations to service debt and interest payments.

     Our 5.75% Convertible subordinated notes (“Notes”) are due in June 2006. We are currently evaluating alternatives to meet this payment obligation.

     Senior Secured Credit Facilities

     On April 22, 2003, we entered into a new $200.0 million senior secured credit facility consisting of a $170.0 million term loan maturing January 31, 2006 (the “2006 Term Loan”) and a $30.0 million revolving line of credit that was available through October 2005. The funds available under this new credit facility were used to repay a $96.9 million term loan previously outstanding and for general corporate purposes. In March 2004, with the proceeds from our 7.125% senior notes (discussed further below), we satisfied in full the 2006 Term Loan, which carried a balance of $168.7 million. In connection with the satisfaction of the 2006 Term Loan, we recorded charges during the first quarter of 2004 of $1.7 million for the associated premiums paid and $1.0 million for the associated unamortized deferred debt issuance costs.

     In June 2004, we entered into a new $30.0 million senior secured revolving credit facility (the “Facility”). The Facility, which is available through June 2007, replaced our prior $30.0 million secured revolving line of credit which was scheduled to mature on October 31, 2005. At March 31, 2005, there was $29.7 million available under this Facility. As of March 31, 2005, we have outstanding $0.3 million of standby letters of credit. Such standby letters of credit are used in our ordinary course of business and are collateralized by our cash balances.

11

     In October 2004, we entered into a new $300.0 million term loan credit facility with a group of institutional lenders. The term loan bears interest at a rate of LIBOR plus 450 basis points and matures in October 2010. The net proceeds of $288.8 million from the term loan were raised for working capital and general corporate purposes.

     Senior Notes

     In March 2004, we sold $250.0 million of 7.125% senior notes due March 2011. The notes were priced at 99.321% of the $250.0 million face value, yielding an effective interest rate of 7.25%. We sold these notes in a private placement and the notes were resold to qualified institutional investors. We used the net proceeds of the issuance to satisfy in full our outstanding term loan due 2006 of $168.7 million and used the remainder of the proceeds for general corporate purposes, including working capital and capital expenditures. The notes have a coupon rate of 7.125% annually and interest payments are due semi-annually. In connection with the offering of these notes, we entered into a registration rights agreement with the purchasers. The registration rights agreement entitled the purchasers, within 210 days from the original issuance, to exchange their notes for registered notes with substantially identical terms as the original notes. We filed a registration statement with the Securities and Exchange Commission for the exchange of the notes, and the exchange was completed in July 2004.

     At March 31, 2005 we were in compliance with all debt covenants contained in our loan agreements and have met all debt payment obligations.

     Notes Payable and Other Debt

     At March 31, 2005 our notes payable balance primarily consists of a $15.2 million note (net of a $0.3 million unamortized debt discount) related to our Unitive acquisitions, of which $15.5 million is due in the third quarter of 2005. At March 31, 2005 our other debt primarily relates to our foreign subsidiaries. The significant components of other debt include term debt and a revolving line of credit. One of our Japanese subsidiaries utilizes the revolving line of credit for working capital purposes and term debt for equipment financing. The revolving line of credit is due in the fourth quarter of 2005 and we expect to extend the agreement or refinance the amount owed. In addition, our Taiwanese subsidiaries have various amounts of term debt maturing between 2005 and 2010. These debt instruments do not include significant financial covenants.

10. Pension and Severance Plans

     Our Philippine, Taiwan and Japanese subsidiaries sponsor defined benefit plans that cover substantially all of their respective employees who are not covered by statutory plans. Charges to expense are based upon costs computed by independent actuaries. The components of net periodic pension cost for these defined benefit plans are as follows:

     For the three months ended March 31, 2005 $0.3 million was contributed to fund the pension plans. We anticipate contributing an additional $4.8 million in 2005 to fund the pension plans.

     Our Korean subsidiary participates in an accrued severance plan that covers employees and directors with one year or more of service. Eligible plan participants are entitled to receive a lump-sum payment upon termination of their employment, based on their length of service and rate of pay at the time of termination. Accrued severance benefits are estimated assuming all eligible employees were to terminate their employment at the balance sheet date. The contributions to the national pension fund made under the National Pension Plan of the Republic of Korea are deducted from accrued severance benefit liabilities. For the three months ended March 31, 2005 and 2004, the provision recorded for severance

12

benefits was $7.1 million and $4.3 million, respectively. The balance recorded in long-term liabilities for accrued severance was $99.5 million and $92.0 million at March 31, 2005 and December 31, 2004, respectively.

11. Earnings Per Share

     Statement of Financial Accounting Standards (SFAS) No. 128, “Earnings Per Share,” requires dual presentation of basic and diluted earnings per share on the face of the income statement. Basic EPS is computed using only the weighted average number of common shares outstanding for the period, while diluted EPS is computed assuming conversion of all dilutive securities, such as options, convertible debt and warrants. For the three months ended March 31, 2005, we excluded from the computation of diluted earnings per share 17.4 million and 9.2 million for outstanding options and convertible notes for common stock, respectively, potentially dilutive securities which would have an antidilutive effect on EPS due to our net loss for the period. For the three months ended March 31, 2004, potentially dilutive securities related to outstanding options, our convertible notes and warrants of 10.4 million, 9.2 million and 3.9 million, respectively, were antidilutive and therefore excluded from the diluted earnings per share calculation.

12. Indemnifications, Guarantees and Contingencies

Indemnifications and Guarantees

     We have indemnified members of our board of directors and our corporate officers against any threatened, pending or completed action or proceeding, whether civil, criminal, administrative or investigative by reason of the fact that the indemnitee is or was a director or officer of the company. These officers and directors are indemnified, to the fullest extent permitted by law, against related expenses, judgments, fines and any amounts paid in settlement. We also maintain Directors and Officers insurance coverage in order to mitigate our exposure to these indemnification obligations. The maximum amount of future payments is generally unlimited. Due to the nature of this indemnification, it is not possible to make a reasonable estimate of the maximum potential loss or range of loss. No assets are held as collateral and no specific recourse provisions exist related to this indemnification.

     We generally provide a standard ninety-day warranty on our services. Our warranty activity has historically been immaterial and is expected to continue to be immaterial in the foreseeable future.

Litigation

     We are currently a party to various legal proceedings, including those noted below. If an unfavorable ruling were to occur, there exists the possibility of a material adverse impact on our net results in the period in which the ruling occurs. The estimate of the potential impact from the following legal proceedings on our financial position or overall results of operations could change in the future. Attorney fees related to legal matters are expensed as incurred.

Epoxy Mold Compound Litigation

     We have become party to an increased number of litigation matters relative to our historic levels. Much of our recent increase in litigation relates to an allegedly defective epoxy mold compound, formerly used in some of our packaging services, which is alleged to be responsible for certain semiconductor chip failures. In the case of each of the pending matters, we believe we have meritorious defenses, as well as valid third-party claims against Sumitomo Bakelite Co., Ltd. (“Sumitomo Bakelite”), the manufacturer of the challenged epoxy product, should the epoxy mold compound be found to be defective. We cannot be certain, however, that we will be able to recover any amount from Sumitomo Bakelite if we are held liable in these matters, or that any adverse result would not have a material impact upon us. Moreover, other customers of

13

ours have made inquiries about the epoxy mold compound, which was widely used in the semiconductor industry, and no assurance can be given that claims similar to those already asserted will not be made against us by other customers in the future.

     Fujitsu Limited v. Cirrus Logic, Inc., et al.

     On April 16, 2002, we were served with a third-party complaint in an action entitled Fujitsu Limited v. Cirrus Logic, Inc., in the United States District Court for the Northern District of California, San Jose Division. Subsequently, substantially the same case was filed in the Superior Court of California, Santa Clara County, and the United States District Court case was stayed. In this action, Fujitsu Limited (“Fujitsu”) alleged that semiconductor devices it purchased from Cirrus Logic, Inc. (“Cirrus Logic”) were defective in that a certain epoxy mold compound manufactured by Sumitomo Bakelite and used by Amkor in the manufacture of the chip causes a short circuit which renders Fujitsu disk drive products inoperable. Cirrus Logic, in response, denied the allegations of the complaint, counterclaimed against Fujitsu for unpaid invoices, and filed its third-party complaint against us alleging that any liability for chip defects should be assigned to us because we assembled the subject semiconductor devices. We filed a cross-complaint against Sumitomo Bakelite asserting claims for breach of warranties and indemnification.

     On April 18 and 19, 2005, we participated in a private mediation with all parties involved. As a result of the mediation, on April 28, 2005 an agreement was reached among Fujitsu, Cirrus Logic, Sumitomo Bakelite and ourselves to settle this litigation; the parties entered the agreement into the record in Superior Court. We have agreed to pay $40 million to Fujitsu in consideration of a release from and dismissal of all claims related to this litigation. This amount is reflected as part of the provision for legal settlements and contingencies in our Statement of Operations for the three months ended March 31, 2005. The $40 million is expected to be paid during the second quarter of fiscal 2005.

     Seagate Technology LLC v. Atmel Corporation, et al.

     In March 2003, we were served with a cross-complaint in an action between Seagate Technology LLC and Seagate Technology International (“Seagate”) and Atmel Corporation and Atmel Sarl (“Atmel”) in the Superior Court of California, Santa Clara County. Atmel’s cross-complaint seeks indemnification from us for any damages incurred from the claims by Seagate involving the allegedly defective epoxy mold compound manufactured by Sumitomo Bakelite. We answered Atmel’s cross-complaint, denying all liability, and filed a cross-complaint against Sumitomo Bakelite. Atmel later amended its cross-complaint to include claims for negligence and negligent misrepresentation against us and added ChipPAC Inc. (“ChipPAC”) and Sumitomo Bakelite as cross-defendants. ChipPAC filed a cross-complaint against Sumitomo Bakelite and us.

     On April 14, 2005 an agreement was reached among Seagate, Atmel, ChipPAC, Sumitomo Bakelite and ourselves to settle this litigation. We have agreed to pay $5 million to Seagate in consideration of a release from and dismissal of all claims related to this litigation. This amount is reflected as part of the provision for legal settlements and contingencies in our Statement of Operations for the three months ended March 31, 2005. The $5 million is expected to be paid during the second quarter of fiscal 2005.

     Maxtor Corporation v. Koninklijke Philips Electronics N.V., et al.

     In April 2003, we were served with a cross-complaint in an action between Maxtor Corporation (“Maxtor”) and Koninklijke Philips Electronics (“Philips”) in the Superior Court of California, Santa Clara County. Philips’ cross-complaint sought indemnification from us for any damages incurred from the claims by Maxtor involving the allegedly defective epoxy mold compound manufactured by Sumitomo Bakelite. Philips subsequently filed a cross-complaint directly against Sumitomo Bakelite, alleging, among other things, that Sumitomo Bakelite breached its contractual obligations to both us and Philips by supplying a defective mold compound resulting in the failure of certain Philips semiconductor devices. We denied all liability in this matter and also asserted a cross-complaint against Sumitomo Bakelite. Sumitomo Bakelite denied any liability. Maxtor and Philips reached a settlement of Maxtor’s claims against Philips on or about April 28, 2004 in which, reportedly, Philips agreed to pay Maxtor $24.8 million. On October 15, 2004, we and Sumitomo Bakelite reached a settlement agreement whereby Sumitomo Bakelite agreed to indemnify us for any damages awarded to Philips in excess of $3.5 million. In exchange, we dismissed our cross-claims against Sumitomo Bakelite. Trial of this matter before a jury began on October 18, 2004 and closing arguments were heard on November 29, 2004. On December 1, 2004, the Court and the jury rendered verdicts in our favor related to all of Philips’ claims against us. By those verdicts, we were exonerated of all alleged liability. The jury’s verdict further determined Sumitomo Bakelite’s share of liability to be 57% and Philips’ share to be 43%. Philips

14

has agreed not to appeal the judgment in our favor in return for our agreement not to seek costs of suit from Philips. In January 2005, Sumitomo Bakelite appealed the judgment against it.

     We recorded a charge of $1.5 million related to the above matter during the three months ended March 31, 2004. However, in response to the December 1, 2004 verdict, we reversed this charge during the three months ended December 31, 2004.

Pending Epoxy Mold Litigation

     While the ultimate outcome is uncertain, as a result of the previously discussed epoxy mold compound litigation settlements, we have established a $5 million loss accrual related to the following two pending claims. This amount is reflected as part of the provision for legal settlements and contingencies in our Statement of Operations for the three months ended March 31, 2005.

     Maxim Integrated Products, Inc. v. Amkor Technology, Inc., et al.

     In August 2003, we were served with a complaint filed by Maxim Integrated Products, Inc. (“Maxim”) against us, Sumitomo Bakelite and Sumitomo Plastics America, Inc. (“Sumitomo Plastics”) in the Superior Court of California, Santa Clara County. The complaint seeks damages related to our use of Sumitomo Bakelite’s epoxy mold compound in assembling Maxim’s semiconductor packages. Written discovery is ongoing, with depositions and expert discovery to follow. The Court has set a trial date of April 24, 2006. We have denied all liability. We intend to defend ourselves vigorously, pursue our cross-claims against Sumitomo Bakelite and seek judgment in our favor.

     Fairchild Semiconductor Corporation v. Sumitomo Bakelite Singapore Pte. Ltd., et al.

     In September 2003, we were served with an amended complaint filed by Fairchild Semiconductor Corporation (“Fairchild”) against us, Sumitomo Bakelite, Sumitomo Plastics and Sumitomo Bakelite Singapore Pte. Ltd. in the Superior Court of California, Santa Clara County. The amended complaint seeks damages related to our use of Sumitomo Bakelite’s epoxy mold compound in assembling Fairchild’s semiconductor packages. Trial is currently scheduled to commence on November 7, 2005, and to last 15 court days. We have denied all liability. We intend to defend ourselves vigorously, pursue our cross-claims against Sumitomo Bakelite and seek judgment in our favor.

Other Litigation

     Amkor Technology, Inc. v. Motorola, Inc.

     In August 2002, we filed a complaint against Motorola, Inc. (“Motorola”) seeking declaratory judgment relating to a controversy between us and Motorola concerning: (i) the assignment by Citizen Watch Co., Ltd. (“Citizen”) to us of a Patent License Agreement dated January 25, 1996 between Motorola and Citizen (the “License Agreement”) and concurrent assignment by Citizen to us of Citizen’s interest in U.S. Patents 5,241,133 and 5,216,278 (the “‘133 and ‘278 patents”); and (ii) our obligation to make certain payments pursuant to an immunity agreement (the “Immunity Agreement”) dated June 30, 1993 between us and Motorola, pending in the Superior Court of the State of Delaware in and for New Castle County.

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

     We and Motorola both filed motions for summary judgment on the remaining claims, and oral arguments were heard in September 2003. On October 6, 2003, the Superior Court of Delaware ruled in favor of us and issued an Opinion and Order granting our motion for summary judgment and denying Motorola’s motion for summary judgment. On October 22, 2003, Motorola filed an appeal in the Supreme Court of Delaware. In May 2004, the Supreme Court reversed the Superior Court’s decision, and remanded for further development of the factual record. A trial date has been set for October 17, 2005. We believe we will prevail on the merits at the Superior Court level. In addition, should Motorola prevail, we believe we will have recourse against Citizen.

     Citizen Watch Co. Ltd. v. Amkor Technology, Inc.

15

     We entered into an intellectual property assignment agreement (“IPAA”) with Citizen Watch Co., Ltd. (“Citizen”) with an effective date of March 28, 2002, pursuant to which Citizen assigned to us (i) its rights under a Patent License Agreement dated January 25, 1996 between Motorola and Citizen (the “License Agreement”) and (ii) Citizen’s interest in the ‘133 and ‘278 patents. The parties entered into the IPAA in conjunction with having entered into a Master Purchase Agreement under which we purchased substantially all of the assets of a division of Citizen in April 2002. Subsequent to that transaction, Motorola challenged the validity of Citizen’s assignment of its rights under the License Agreement to us, which resulted in our litigation with Motorola, Inc., which is described above (the “Motorola case”). Pending resolution of the Motorola case, and in accordance with the terms of the IPAA, we are withholding final payment of 1.4 billion yen ($13.0 million based on the spot exchange rate at March 31, 2005).

     In March 2004, Citizen submitted a Demand for Arbitration in the International Chamber of Commerce (“ICC”), claiming breach of our obligation to make the deferred payment of 1.4 billion yen. In May 2004, we filed our Answer to Request for Arbitration, Counterclaim and Request for Abeyance of Proceedings. In our Answer, we contend, among other things, that we do not have an obligation to make the deferred payment due to (i) our inability to perfect the rights assigned by Citizen under the License Agreement, and (ii) Citizen’s breach of its representations and warranties that it had all right and authority to assign its rights under the License Agreement to us.

     The arbitration hearing before the ICC on this matter was held in May 2005. A ruling by the ICC is expected by July 31, 2005.

     Alcatel Business Systems v. Amkor Technology, Inc., Anam Semiconductor, Inc.

     On November 5, 1999, we agreed to sell certain semiconductor parts to Alcatel Microelectronics, N.V. (“AME”), a subsidiary of Alcatel S.A. The parts were manufactured for us by Anam Semiconductor, Inc. (“ASI”) and delivered to AME. AME transferred the parts to another Alcatel subsidiary, Alcatel Business Systems (“ABS”), which incorporated the parts into cellular phone products. In early 2001, a dispute arose as to whether the parts sold by us were defective. On March 18, 2002, ABS and its insurer filed suit against us and ASI in the Paris Commercial Court of France, claiming damages of approximately 50.4 million Euros (approximately $65.1 million based on the spot exchange rate at March 31, 2005). We have denied all liability and intend to vigorously defend ourselves and have not established a loss accrual associated with this claim. Additionally, we have entered into a written agreement with ASI whereby ASI has agreed to indemnify us fully against any and all loss related to the claims of AME, ABS and ABS’ insurer. The Paris Commercial Court commenced a special proceeding before a technical expert to report on the facts of the dispute. The report of the court-appointed expert was put forth on December 31, 2003. The report does not specifically allocate liability to any particular party. On May 18, 2004, the Paris Commercial Court of France declared that it did not have jurisdiction over the matter. The Court of Appeal of Paris heard the appeal regarding jurisdiction during October 2004, confirmed the first tier ruling and dismissed the appeal. A motion was recently filed by ABS and its insurer before the French Supreme Court to challenge the lack of jurisdiction ruling.

     In response to the French lawsuit, on May 22, 2002, we filed a petition to compel arbitration in the United States District Court for the Eastern District of Pennsylvania (the “Court”) against ABS, AME and ABS’ insurer, claiming that the dispute is subject to the arbitration clause of the November 5, 1999 agreement between us and AME. ABS and ABS’ insurer have refused to arbitrate and continue to challenge the lack of jurisdiction ruling.

     Amkor Technology, Inc. v. Carsem (M) Sdn Bhd, Carsem Semiconductor Sdn Bhd, and Carsem Inc.

     In November 2003, we filed complaints against Carsem (M) Sdn Bhd, Carsem Semiconductor Sdn Bhd, and Carsem Inc. (collectively “Carsem”) with the International Trade Commission (“ITC”) in Washington, D.C. and subsequently in the Northern District of California. The complaints allege infringement of our United States Patent Nos. 6,433,277, 6,455,356, and 6,630,728 (collectively the “Amkor Patents”). We allege that by making, using, selling, offering for sale, or importing into the U.S. the Carsem Dual and Quad Flat No-Lead Package, Carsem has infringed on one or more of our MicroLeadFrame® packaging technology claims in the Amkor Patents. The District Court action had been stayed pending resolution of the ITC case. The ITC Administrative Law Judge conducted an evidentiary hearing during July and August of 2004 in Washington D.C. and issued an initial determination that Carsem infringed some of our patent claims relating to our MicroLeadFrame® package technology, that some of our 21 asserted patent claims are valid, and that all of our asserted patent claims are enforceable. However, the judge did not find a statutory violation of the Tariff Act. We filed a petition in November 2004 to have the judge’s ruling reviewed by the full International Trade Commission. The Commission has ordered a new claims construction related to various disputed claim terms and has remanded the case to the Administrative

16

Law Judge for further proceedings. The Commission has set a new date of November 21, 2005 for completion of the investigation. The District court action remains stayed pending completion of the ITC investigation.

     Other Matters

     In June 2004, the Securities and Exchange Commission informed us that it was conducting an informal inquiry into certain trading in Amkor securities. The focus of the inquiry appears to be activities during the first half of 2004. We have cooperated with the inquiry by voluntarily producing documents to the Commission and providing testimony. The Commission staff has not informed us of any conclusions of wrongdoing by any person or entity.
