Dividends include a cash dividend of NT$3.02507290 for each common share
and a stock distribution of 5.04178823 shares per 1,000 common shares

Hsinchu, Taiwan, R.O.C. — July 1, 2008 — TSMC (TAIEX: 2330, NYSE: TSM) today announced that the ex-dividend date for TSMC common shares shall be July 16, 2008. The dividends include a cash dividend of NT$3.02507290 for each common share and a stock distribution of 5.04178823 shares per 1,000 common shares.

The above-mentioned dividend was calculated based on the total amount of profits to be distributed and capital surplus to be capitalized, as approved by the Company’s shareholder meeting on June 13, 2008, and the actual number of common shares outstanding on the record date for said dividend distribution. As a result of the employee stock options exercised and TSMC share buy back between the day the Company’s board proposed said dividend distribution, and the record date of the distribution, the total number of outstanding common shares has decreased slightly, resulting in a miniscule difference in the per-share dividends from the per-share amount proposed by the Company’s board on February 19, 2008.
