Kim’s children and grandchildren, the Foundation and the Partnership, who each exercise voting or investment power with respect to shares of the Issuer’s Common Stock in concert with other members of the Group. James J. Kim, as general partner of the Partnership, has voting and investment power with respect to the Partnership. All of the directors and officers of the Foundation are members of the Kim Family. Accordingly, the Foundation might be expected to vote the shares of Common Stock of the Issuer that the Foundation owns in concert with the Kim Family, the Kim Trusts and the Partnership.

James J. Kim, the Foundation, Irrevocable Deed of Trust of James J. Kim for Jacqueline Mary Panichello dated 10/3/94, Irrevocable Deed of Trust of James J. Kim for Alexandra Kim Panichello dated 12/24/92, Irrevocable Deed of Trust of James J. Kim for Dylan James Panichello dated 10/15/01, Irrevocable Deed of Trust of James J. Kim for Allyson Lee Kim dated 10/15/01, Irrevocable Deed of Trust of James J. Kim FBO Jason Lee Kim dated 11/17/03 and Irrevocable Deed of Trust of James J. Kim f/b/o Children of David D. Kim dated 11/11/05 (collectively, the “2005 Investors”) entered into a voting agreement dated as of November 18, 2005 (the “2005 Voting Agreement”). Pursuant to the 2005 Voting Agreement, the 2005 Investors agreed to vote all shares of Amkor Common Stock issued upon conversion of the 6 1/4% convertible subordinated notes (the “2005 Notes” and upon conversion to Amkor Common Stock, the “2005 Converted Shares”) in accordance with the 2005 Voting Agreement. The 2005 Investors agree to vote all 2005 Converted Shares in a “neutral manner” on all matters submitted to Amkor stockholders for a vote, such that the shares subject to the 2005 Voting Agreement are required to be voted in the same proportion as all of the other outstanding securities (excluding securities beneficially owned, directly or indirectly, by the 2005 Investors) that are actually voted on a proposal submitted to Amkor’s stockholders for approval. The 2005 Investors are not required to vote in a “neutral manner” any 2005 Converted Shares that, when aggregated with all other voting shares held by the 2005 Investors, represent 41.6% or less of the total then-outstanding voting shares of Amkor Common Stock. The 2005 Voting Agreement shall terminate upon the earliest of (i) December 1, 2013, (ii) such time as no principal amount of 2005 Notes or any 2005 Converted Shares remains outstanding, (iii) a change of control transaction (as defined in the 2005 Voting Agreement) of Amkor, or (iv) the mutual agreement of the 2005 Investors and Amkor. A copy of the 2005 Voting Agreement is attached as Exhibit 10.1 to Amendment No. 3 of this Statement and incorporated herein by reference.

The James J. Kim 2008 Trust FBO Alexandra Kim Panichello and Descendants, the James J. Kim 2008 Trust FBO Jacqueline Mary Panichello and Descendants, the James J. Kim 2008 Trust FBO Dylan James Panichello and Descendants, the James J. Kim 2008 Trust FBO Descendants of John T. Kim and the James J. Kim 2008 Trust FBO Descendants of David D. Kim are collectively referred to as the “2008 Trusts”. On February 11, 2008, the 2008 Trusts acquired an aggregate of 8,180,400 shares of Common Stock from Agnes C. Kim in a private transaction and financed such purchase by issuing promissory notes maturing on February 10, 2011, which on December 31, 2008 were replaced with promissory notes maturing on December 31, 2016 (the “2008 Notes”). In connection with the 2008 Notes, the 8,180,400 shares held by the 2008 Trusts have been pledged to Agnes C. Kim as collateral for the 2008 Notes. If an event of default with respect to any of the 2008 Notes occurs, which may include failure to make note payments when due, default in a payment of other borrowed money, distribution of a

substantial part of a trust’s property or judgments exceeding $25,000 being entered against a trust, Agnes C. Kim may declare any of the 2008 Notes in default and acquire voting and investment power with respect to the shares pledged as collateral.

In connection with the issuance of the $150 million of a 6.00% convertible senior subordinated note due April 15, 2014 (the “2009 Note”), James J. Kim and the Partnership (collectively, the “2009 Investors”) and Amkor entered into a voting agreement dated as of March 26, 2009 (the “2009 Voting Agreement”). Pursuant to the 2009 Voting Agreement, the 2009 Investors agreed to vote all shares of Amkor Common Stock issued upon conversion of the 2009 Note (the “2009 Converted Shares”) in accordance with the 2009 Voting Agreement. The 2009 Investors agree to vote all 2009 Converted Shares in a “neutral manner” on all matters submitted to Amkor stockholders for a vote, such that the shares subject to the 2009 Voting Agreement are required to be voted in the same proportion as all of the other outstanding securities (excluding securities beneficially owned, directly or indirectly, by the 2009 Investors) that are actually voted on a proposal submitted to Amkor’s stockholders for approval. The 2009 Investors are not required to vote in a “neutral manner” any 2009 Converted Shares that, when aggregated with all other voting shares held by the 2009 Investors, represent 41.6% or less of the total then-outstanding voting shares of Amkor Common Stock. The 2009 Voting Agreement shall terminate upon the earliest of (i) such time as no principal amount of the 2009 Note remains outstanding and the 2009 Investors or their affiliates no longer beneficially own any of the 2009 Converted Shares, (ii) consummation of a change of control (as defined in the 2009 Voting Agreement) of Amkor, or (iii) the mutual agreement of the 2009 Investors and Amkor. A copy of the 2009 Voting Agreement is attached as Exhibit 10.2 to Amendment No. 3 of this Statement and incorporated herein by reference.

In addition, the 2009 Investors, Deutsche Bank Securities Inc. (“Deutsche Bank”) and Citigroup Global Markets Inc. (“Citigroup”) entered into a commitment letter on March 25, 2009 (the “Commitment Letter”) pursuant to which the 2009 Investors agreed to purchase in the aggregate a minimum of $150 million and up to a maximum of $200 million of promissory notes in the April 1, 2009 offering. Pursuant to the Commitment Letter, the 2009 Investors entered into a lock-up agreement with Deutsche Bank and Citigroup for a lock-up period of ninety days after April 1, 2009 in which the 2009 Investors agree not to, directly or indirectly, offer, sell, contract to sell, pledge or otherwise dispose of or enter into any transaction which is designed to or might reasonably be expected to result in the disposition by the 2009 Investors or any their affiliates or any person in privity with the 2009 Investors of any shares of capital stock of Amkor or any securities convertible into or exercisable or exchangeable for such capital stock with certain limited exceptions, including the exercise of options, transactions pursuant to Rule 10b5-1 or in certain circumstances when the transferee agrees to be bound by these restrictions. A copy of the Commitment Letter, including the form of lock-up agreement executed on March 25, 2009 by the 2009 Investors, Deutsche Bank and Citigroup, is attached as Exhibit 10.3 to Amendment No. 3 of this Statement and incorporated herein by reference.

Amkor and the 2009 Investors also entered into a letter agreement dated March 26, 2009 (the “Letter Agreement”) pursuant to which, among other things, Amkor agreed to use reasonable efforts to register the resale of the 2009 Note (and any shares of Common Stock issued upon the conversion thereof) on a shelf registration statement pursuant to Rule 415 under the Securities Act of 1933, as amended (the “Securities Act”), upon the request of the 2009 Investors at any time after April 1, 2010. Amkor agreed to reimburse James J. Kim for the reasonable legal fees and expenses incurred by Mr. Kim in connection with the negotiation and purchase of the 2009 Note by the Partnership. A copy of the Letter Agreement is attached as Exhibit 10.4 to Amendment No. 3 of this Statement and incorporated herein by reference.

Finally, Amkor executed the 2009 Note in favor of the Partnership, which matures on April 15, 2014. The 2009 Note accrues interest at a rate of 6.00% per year, which is subject to increase in certain circumstances, and is payable semi-annually in arrears on April 15 and October 15 of each year commencing October 15, 2009. The 2009 Note may be converted at any time by the 2009 Investors into shares of Common Stock at an initial conversion rate of 330.6332 shares of Common Stock per $1,000 principal amount of 2009 Note, subject to certain adjustments, which represent a conversion price of approximately $3.02 per share of Common Stock. Upon the occurrence of a designated event, which includes a change of control or termination of trading, the 2009 Investors

may require Amkor to repurchase the 2009 Note at a price equal to 100% of the principal amount plus accrued and unpaid interest up to but excluding the repurchase date. The 2009 Note contains certain events of default that could, subject to certain conditions, cause the unpaid principal amount plus accrued and unpaid interest on the 2009 Note to be due and payable, which include default in the payment of principal or installment interest, default in the delivery when due of any Common Stock deliverable upon conversion, breach of covenants, failure to provide timely notice of any designated event, failure of Amkor or any of its material subsidiaries to make timely payment of debt in excess of $20 million and certain events of bankruptcy or insolvency of Amkor or any of its material subsidiaries. The shares issuable upon conversion of the 2009 Note have not been registered under the Securities Act. All of the notes issued in connection with the April 1, 2009 note offering, including the 2009 Note, are subordinated to the 2005 Notes. A copy of the form of 2009 Note is attached as Exhibit 10.5 to Amendment No. 3 of this Statement and incorporated herein by reference.

The trust agreements for certain of the Kim Trusts authorize the trustees of such trusts to vote the shares of Common Stock of the Issuer held by them, in their discretion, in concert with members of the Kim Family. The Partnership grants James J. Kim, its general partner, sole voting and investment power with respect to all of the securities held by the Partnership. James J. and Agnes C. Kim are husband and wife. James J. Kim and Agnes C. Kim are the parents of Susan Y. Kim, David D. Kim and John T. Kim. Each of the David D. Kim Trust of 12/31/87, the John T. Kim Trust of 12/31/87 and the Susan Y. Kim Trust of 12/31/87 has as their sole trustee David D. Kim, John T. Kim and Susan Y. Kim, respectively. Susan Y.
