TSMC Monthly Sales Report - January 1999

Hsin-Chu, Taiwan, February 9, 1999- Taiwan Semiconductor Manufacturing Company Ltd. (TAIEX: 2330, NYSE: TSM), ("TSMC" or "the Company" ) today announced that its net sales for January, 1999, were NT$3,845 million.

Mr. YC Huang, Spokesman of TSMC, stated that as a result of an obvious pick-up in order volume, unit sales in January, 1999 increased on a month-over-month comparison. The increase of unit sales consequently contributed to a 11.2% growth in sales revenues of January, 1999 compared with those of December, 1998. However, due to the relatively unfavorable unit sales and average selling price in comparison with those of early 1998 when TSMC was in the midst of its peak sales period, sales revenues of January, 1999 decreased 29.4% over the same period a year ago.
