The company plans to fund the Offer with proceeds from a $180,000,000 term loan by Woori Bank to the company’s wholly-owned Korean subsidiary (the “Term Loan”).

The “Tender Offer Consideration” for each $1,000 principal amount of the Notes tendered and accepted for payment pursuant to the Offer will be $1,020. Registered holders (“Holders”) of Notes that are validly tendered and not validly withdrawn on or before 5:00 p.m., New York City time, on June 7, 2010 (the “Early Tender Date”), and accepted for purchase will receive the Tender Offer Consideration plus $30 for each $1,000 principal amount of Notes (the “Early Tender Premium”, and together with the Tender Offer Consideration, $1,050 or the “Total Consideration”). Holders of Notes that are validly tendered after the Early Tender Date and not validly withdrawn on or before 11:59 p.m., New York City time, on June 21, 2010 (the “Expiration Date”) and accepted for purchase will receive only the Tender Offer Consideration. In addition to the Tender Offer Consideration or the Total Consideration, as the case may be, payable in respect of Notes accepted for purchase, Holders will receive accrued and unpaid interest on their purchased Notes from the last interest payment date up to, but not including, the date of payment for purchased Notes.

As of today, the aggregate outstanding principal amount of the Notes is $390,000,000. In the event that the amount of Notes validly tendered and not validly withdrawn on or prior to the Expiration Date exceeds $175,000,000, the company will accept for payment the Notes that are validly tendered and not validly withdrawn on a pro rata basis from among the tendered Notes.

Securities tendered on or before the Early Tender Date may be validly withdrawn at any time on or before 5:00 p.m., New York City time, on the Early Tender Date, but not thereafter, and securities tendered after the Early Tender Date but on or before the Expiration Date may not be withdrawn, provided, however, that if Amkor amends the Offer in a manner that is materially adverse to Holders that have previously tendered, the company will extend withdrawl rights for a period it reasonably determines will afford Holders a reasonable opportunity to assess such amended terms.

The Offer is scheduled to expire at 11:59 p.m., New York City time, on Monday, June 21, 2010, unless extended. The tender offer will not be contingent upon any minimum number of Notes being tendered. The tender offer, however, will be subject to certain conditions, including the consummation of the Term Loan on terms reasonably satisfactory to the company and the receipt of the Term Loan proceeds. None of Amkor, its board of directors, the dealer manager, the depositary, or the information agent is making any recommendations to Holders of Notes as to whether to tender or refrain from tendering their Notes into the tender offer. Holders of Notes must decide how many Notes they will tender, if any.

The complete terms and conditions of the Offer are set forth in the Offer to Purchase and Letter of Transmittal that are being sent to Holders of Notes. Holders are urged to read the tender offer documents carefully. Copies of the Offer to Purchase and Letter of Transmittal may be obtained from the Information Agent for the Offer, Global Bondholder Services, at (866) 804-2200 (toll-free).
