CORPORATE RELEASE

STATS ChipPAC Acquires LSI’s Assembly and Test
Operation in Thailand

United States — 7/25/2007, Singapore — 7/26/2007 — STATS ChipPAC Ltd. (“STATS ChipPAC” or the “Company” — NASDAQ: STTS and SGX-ST: STATSChP), a leading independent semiconductor test and advanced packaging service provider, and LSI Corporation (NYSE: LSI) today announced a definitive agreement for STATS ChipPAC to acquire LSI’s assembly and test operation in Pathumthani, Thailand for an aggregate purchase price of approximately $100 million.

Under the terms of the agreement, STATS ChipPAC will acquire LSI’s assembly and test operation in Thailand which consists of a facility with approximately 440,000 square feet of floor space, manufacturing equipment and certain other assets. STATS ChipPAC will offer employment contracts to LSI employees in the Thailand facility. LSI will further enter into a long-term supply agreement with STATS ChipPAC for their assembly and test services needs.

“The acquisition of LSI’s Thailand facility and its world class workforce secures long term business commitment from LSI to STATS ChipPAC and reinforces our position in the data storage and communications market. It also adds scale and improves the economies of scale of our leadframe business. Over the years, we have built a strong relationship with LSI and we are pleased to expand the level of services and support we can offer them,” said Tan Lay Koon, President and Chief Executive Officer of STATS ChipPAC.

“LSI’s strategic agreement with STATS ChipPAC provides a tremendous amount of value to both companies.

It also provides us with assured capacity and access to the same high quality assembly and test services that LSI requires going forward,” said Andy Micallef, Executive Vice President of Operations, LSI.

The transaction is expected to close within 90 days, subject to the satisfaction of customary closing conditions and regulatory approvals.
