Gas Natural has extended the expiration date of its US offer for Endesa to November 17, 2006, unless the offer is further extended, lapses or is withdrawn.

Gas Natural’s obligation to complete its US offer is conditional on, among other things, the completion of its Spanish offer, which has been temporarily suspended as a result of the injunctions issued by the Court for Business Matters in Madrid and the Spanish Supreme Court. The suspension of the Spanish offer is currently pending resolution of Gas Natural’s appeals, as well as the underlying lawsuits.

Gas Natural said that it intends to cause the offer periods of its US offer and Spanish offer to end at the same time.

Gas Natural’s US offer is open to all holders of Endesa ordinary shares who are located in the US and to all holders of Endesa ADSs, wherever located.
