U.S. Disclaimer – Unsponsored ADR (American Depository Receipt)

Effective October 10, 2008, the United States Securities and Exchange Commission (“SEC”) , by revising U.S. Exchange Act Rule 12g3-2(b), made it possible for depository institutions or banks to establish ADR programs without the participation of a non-U.S. issuer (a so called “Unsponsored ADR”). An ADR, or American Depositary Receipt, is a negotiable receipt, similar to a stock certificate, which is issued by a U.S. bank or depository to evidence an ordinary share of a non-U.S. issuer that has been deposited with the U.S. bank or depository. ADRs permit a U.S. investor to purchase in the U.S. market an interest in a non-U.S. issuer’s securities. An ADR program which is unsponsored is set up without the non-U.S. issuer’s cooperation or even its consent. Shin-Etsu Chemical Co., Ltd. (the “Company”) does not support or encourage the creation of Unsponsored ADR programs in respect of its securities and in any event disclaims any liability in connection with an Unsponsored ADR. The Company does not represent to any depository institution, bank or anyone nor should any such entity/person rely on a belief that the website of the Company includes all published information in English, currently, and on an ongoing basis, required to claim an exemption under U.S.Exchange Act Rule 12g3-2(b).
