ASE Inc. and ASE Test Announce Anticipated Effective Date of

Proposed “Going Private” Acquisition of ASE Test by ASE Inc.

May 9, 2008 – Advanced Semiconductor Engineering, Inc. (NYSE: ASX, TAIEX: 2311, “ASE Inc.”) and its majority-owned subsidiary ASE Test Limited (NASDAQ: ASTSF, TAIEX: 9101, “ASE Test”) today announced May 30, 2008 as the anticipated effective date of the proposed “going private” acquisition by ASE Inc. of the outstanding ordinary shares of ASE Test that ASE Inc. does not directly or indirectly own by way of a scheme of arrangement under Singapore law (the “Scheme”).

ASE Inc. and ASE Test announced on May 6, 2008 that the Scheme was approved by the requisite majority of unaffiliated shareholders of ASE Test at the May 6, 2008 meeting of shareholders of ASE Test convened by the order of the High Court of Singapore (the “Court”). ASE Test applied on May 7, 2008 to the Court to sanction the Scheme, and a Court hearing to sanction the Scheme is scheduled to take place on May 22, 2008. The Scheme will only become effective when the order of the Court sanctioning the Scheme is lodged with the Accounting and Corporate Regulatory Authority of Singapore (the “ACRA”).

ASE Inc. and ASE Test currently anticipate that the Scheme will become effective on May 30, 2008, pending the receipt of the order of the Court sanctioning the Scheme, the lodging of such order with the ACRA and the satisfaction of other customary closing conditions. The books closure date for determining the entitlements of shareholders of ASE Test under the Scheme is expected to be the same date as the effective date of the Scheme.
