An American Depositary Receipt ("ADR") is a negotiable receipt issued by a US depositary bank to represent a specified number of ordinary shares of a non-US issuer that has been deposited with the depositary bank or its custodian. As of 10 October 2008, certain amendments to US securities laws became effective which made it easier for depositary banks to establish unsponsored ADR programmes without the participation or consent of the issuer.

Singapore Technologies Engineering Ltd has not authorised and does not support or encourage the establishment of any unsponsored ADR programmes in respect of its securities and disclaims any liability in connection with any unsponsored ADRs. Singapore Technologies Engineering Ltd also does not represent to any depositary bank nor should any depositary bank rely on a belief that Singapore Technologies Engineering Ltd publishes on its website or any electronic information delivery system all information in English currently and on an ongoing basis required to claim or maintain the exemption from registration under Rule 12g3-2(b) under the US Securities Exchange Act of 1934.
