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 terminated pursuant to its terms on December 31, 2013. 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 (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 $150 million of a 6.00% convertible senior subordinated note due April 15, 2014 (the “2009 Note”), James J. Kim and the 915 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. On June 18, 2013, the 2009 Investors exchanged the 2009 Notes for 49,594,980 shares of Common Stock in transactions reported on a Form 4 filed with the Commission on the same date. As a consequence of this conversion, the 2009 Voting Agreement terminated pursuant to its terms. A copy of the 2009 Voting Agreement and the 2009 Note are attached as Exhibits 10.2 and 10.5, respectively, to Amendment No. 3 of this Statement and incorporated herein by reference.

None of the trust agreements for the Kim Trusts prohibit the trustees of such trusts from voting the shares of Common Stock of the Issuer held by them, in their discretion, in concert with members of the Kim Family. The 915 Partnership grants James J. Kim, its general partner, sole voting and investment power with respect to all of the securities held by the 915 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. The David D. Kim Trust of December 31, 1987 has as its sole trustee David D. Kim. The John T. Kim Trust of December 31, 1987 has as its sole trustee John T. Kim. Susan Y.
