Home Jurisdiction Documents. The following document is attached to this Form CB as Exhibit A: News release issued by Telefonica announcing the offer dated June 23, 2003. Item 2. Informational Legends. This offer is made for the securities of a foreign company. The offer is subject to disclosure requirements of a foreign country that are different from those of the United States. Financial Statements included in the document, if any, have been prepared in accordance with foreign accounting standards that may not be comparable to the financial statements of U.S. 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 because the offeror is located in a foreign country and some or all of its officers and directors may be residents of a foreign country. You may not be able to sue a foreign company or its officers or directors in a foreign court for violations of U.S. securities laws. It may be difficult to compel a foreign company and its affiliates to subject themselves to a U.S. court's judgment.
