· Issued by Tsubakimoto Chain Co.

The business combination described in this document involves securities of a Japanese company. The business combination is subject to disclosure requirements of Japan that are different from those of the United States. Financial information included in this document, if any, was excerpted from financial statements prepared in accordance with foreign accounting standards that may not be comparable to the financial statements of United States companies.

It may be difficult for you to enforce your rights and any claim you may have arising under the U.S. federal securities laws, since the issuer is located in Japan and some or all of their officers and directors reside outside of the United States. You may not be able to sue a Japanese company or its officers or directors in a Japanese court for violations of the U.S. securities laws. It may be difficult to compel a Japanese company and its affiliates to subject themselves to a U.S. court's judgment.

You should be aware that the issuer may purchase securities otherwise than under the business combination, such as in the open market or through privately negotiated purchases.
