Advanced Semiconductor Enginnering, Inc. Press Release

TAIPEI, Taiwan, April 17 /Xinhua-PRNewswire-FirstCall/ -- Advance Semiconductor Engineering, Inc. (TAIEX: 2311; NYSE: ASX) ("ASE" or the "Company") announced today that it was notified by the investor consortium led by The Carlyle Group (the "Consortium") that the Consortium would withdraw its plans, originally announced by the Consortium on November 24, 2006, to make an offer to acquire 100% of the outstanding shares of the Company at NT$39 per share (the "Proposed Offer").

The Consortium stated that the reason for withdrawing the Proposed Offer was the inability of the Consortium and the evaluation committee formed by Director T.C. Cheng at the request of the Company's Board of Directors (the "Evaluation Committee") to reach agreement on the proposed offer price after a number of meetings between the Evaluation Committee.

During its most recent meeting with the Evaluation Committee, the Consortium agreed to increase the offer price to NT$39.50 per share. The Evaluation Committee concluded that this proposed offer price did not reflect the value of the Company and informed the Board of the Company and the Consortium that it would not support a transaction at the proposed offer price. Following this, the Company received a letter from the Consortium today (April 17, 2007) stating that the Consortium had determined not to pursue the proposed transaction.
