FOR IMMEDIATE RELEASE

ADDITIONAL INFORMATION OF THE MADECO’S AGREEMENT WITH NEXANS

(Santiago, CHILE, November 16, 2007) Madeco S.A. (“Madeco” or “the Company”) (NYSE ticker: MAD) reported today the following information to the Superintendencia de Valores y Seguros (Chilean Securities and Insurance Superintendency, or “SVS”):

Yesterday in Paris, Madeco and Nexans concluded a Framework Agreement, whereby it was agreed to transfer all the assets of Madeco’s cable units in Chile, Argentina, Peru, Brazil and Colombia to Nexans, at a price of US$448 million plus 2.5 million shares of Nexans, totaling approximately US$823 million.

Madeco complements this given information as follows:

• According to the Framework Agreement, Nexans commits to propose a Madeco’s representative in its Board during the shareholders’ meeting to be carried out in March 2008;

• The financial effects arising from the transaction between Madeco and Nexans would produce an estimated profit of USD 283 million, based on the balance of the book value of assets and liabilities involved in the operation as of September 30, 2007. The estimated profit will be conditioned by the change of value that the factors involved in the transaction can experience between this date and the closure date of the operation. All these effects are being analyzed and will be reviewed by our External Auditors, Ernst & Young, in order to determine the financial effect that the transaction will generate to the Company;

• The signing of the Framework Agreement with Nexans will begin a due diligence process, which will be extended for the period and deadlines established in the Framework Agreement. In case mentioned due diligence was satisfactory to both parties, the final agreement will be implemented in June 2008;

• Madeco S.A. would proceed to separate the cable business units in Chile and Argentina incorporating new subsidiaries. It should also be noted that, because this operation involves the sale of approximately 60% of the Company’s assets, a future Extraordinary Shareholders' Meeting will be arranged in order to agree this issue.
