Philips Completes Exit of TSMC Shareholding

Hsinchu, Taiwan, R.O.C. — August 14, 2008 — TSMC (TAIEX: 2330, NYSE: TSM) today announced that the multi-phased plan for Philips’ exit from its TSMC shareholding, as announced in March 2007, has come to an orderly and successful conclusion.

Philips today sold all of its remaining TSMC common shares through a block trade to long-term financial investors mutually agreed by Philips and TSMC.

Ms. Lora Ho, TSMC Vice President and Chief Financial Officer said: “We are pleased that Philips has successfully exited its holding of TSMC shares. In addition, this block trade does not alter TSMC’s stock buyback program which started on August 13. Meanwhile, we reiterate our commitment to maintaining our current annual cash dividend per share or steadily increase the amount.”
