Trend Micro to be Listed on the First Section of the Tokyo Stock Exchange

Tokyo, Japan August 10, 2000 -Trend Micro Inc (Japan OTC: 4704; Nasdaq: TMIC), a leading provider of enterprise antivirus and Internet security software, today announced that the Tokyo Stock Exchange (TSE) has approved its application to be listed in the stock market's prestigious first section. The shares will be listed on the TSE commencing August 17, 2000, and will simultaneously be delisted from the OTC market. The security trading code will remain the same, 4704, and the company will be classified as a "Service Business."

The Tokyo Stock Exchange is Japan's major international equity exchange. It lists about 2,000 companies on its two main boards, compared to about 900 on the OTC market. The trading volume of shares in the TSE's first section totaled approximately 355 trillion yen in 1999, compared to 15 trillion yen for the second section and 22 trillion yen for the OTC market.

The listing regulations of the Tokyo Stock Exchange, which are much stricter than those of the OTC market, required Trend Micro to meet minimum market capitalization and share listing requirements, in addition to meeting requirements as to the number of shareholders and percentage of shares held by major investors. The company hopes the listing will attract public notice and raise Trend Micro's profile with new investors - particularly institutional investors who may not invest in the OTC market.

Trend Micro held its initial public offering and shares began trading on Japan's over-the-counter market on August 17, 1998. Additional shares were offered in the form of American Depositary Shares and quoted on the Nasdaq National Market in July 1999.
