                Endesa's response to Gas Natural's bid; Endesa:
                     ``Stronger business, greater value.''

     NEW YORK--(BUSINESS WIRE)--Oct. 3, 2005--The following is a transcript of
an interview by UK based Cantos Communications with Endesa's (NYSE: ELE) CEO and
CFO regarding Gas Natural's bid:


     Endesa's response to Gas Natural's bid
     Endesa: "Stronger business, greater value."


     Rafael Miranda Robredo, CEO

     Unacceptable offer

     Q: Why aren't you recommending this takeover to your shareholders?
     A: Because Endesa offers higher value and strong growth with less risk than
        the offer made by Gas Natural, which is completely unacceptable, is at a
        ridiculous price, offers very little cash, no takeover premium and also
        the stock component has a huge risk.

     Q: So what's the reaction of your major shareholders so far?
     A: We are starting our roadshow now.  Within the next three weeks,  we will
        see most of our major  shareholders.  I'm  completely  convinced  that
        they will support us, rejecting the offer of Gas Natural, which is an
        opportunistic offer.



     Q: Why do you think a takeover by Gas Natural would destroy value?
     A: Because they are proposing selling strategic assets cheaply, destroying
        our leading position in Spain. They are also proposing to destroy our
        European platform, which clearly will give us growth of approximately
        15 per cent. in the near future. Also, they are introducing a
        declining business, which is losing market share, and, on top of that,
        there are a lot of execution risks and huge negative synergies.

     Q: But isn't there some logic in integrating electricity and gas going
        forward?
     A: It depends on the integration and with whom you integrate. In the case
        of Gas Natural, Gas Natural is mainly a distribution company. They are
        not adding value to our project. For example, they do not have reserves
        and, also, we are now buying cheaper gas than them.

     Q: Now, you've talked about shareholders losing out, but wouldn't consumers
        actually benefit from this deal?
     A: Clearly no, because they are proposing to create a duopoly in Spain. It
        would also create monopolies for gas and electricity in large regions of
        the country. This would mean that will be a step backwards in the
        liberalisation process of Spain. So, clearly, there is no benefit for
        consumers.

     Growth prospects

     Q: Why do you believe Endesa is stronger as an independent company?
     A: Because we are convinced that Endesa will deliver superior growth and
        value than the combined entity, with less risk.

     Q: But can you  deliver the same growth that can be achieved by a merger of
        the two companies?
     A: Absolutely, yes. The growth, in our case, will come from markets with
        high potential growth, such as Spain and Portugal, which will grow at 7
        per cent., or our business in Italy that will grow close to double
        digits. It will also come from operational improvements and from our
        ongoing cost reduction programme that will deliver us a margin above
        EUR 500m.



     Q: So what are your mid-term targets?
     A: We have clear targets for the next five years. EBITDA will grow between
        10 per cent. to 11 per cent. and the dividend will grow above 12 per
        cent.

     "Stronger business, greater value"

     Q: Germany and France have both effectively created "national champions" in
        the utility sectors. So why shouldn't Spain?
     A: The combined entity would not be larger than the current Endesa. In
        fact, in enterprise value, it would only be 12 per cent. larger than us,
        because they propose to dispose of assets. Also, let me say that, in
        electricity, they are smaller and weaker. I believe that "national
        championship" is an old-fashioned idea and probably an anti-competitive
        idea.

     Q: So why should shareholders stand by this management?
     A: This management is the one that has really created a leading and
        respected company in the world. We have been able to maintain our
        leadership in Spain even after the liberalisation measures in 1997.

        We have created a platform of growth in Europe, being in the top five of
        European utilities. We also have a good business in Latin America. We
        have created value for our shareholders and we are probably now in our
        best moment.

     Q: And are you  looking for a "white  knight"?
     A: All I can say is that we know everybody in the industry. We are very
        well known by the industry and, of course, I am sure that there is a lot
        of interest in this transaction because Endesa is a great company.
        Anything could happen, but I'm sure that Endesa has a clear and great
        future as an independent company.

     Q: So you're confident that Endesa can retain its independence?
     A: Absolutely, yes.



     Jose - Luis Palomo, CFO

     Valuation and bid structure

     Q: Endesa has characterised the Gas Natural bid as cheap and hostile, so
        what would be a fair price for your stock?
     A: Well, I don't want to be specific on the price because I don't want to
        put a cap on the valuation of the company for the shareholders. But the
        bid that we have on the table, and the price, is very low. It's clearly
        very low for the shareholders and the market has already discounted the
        offer in less than two weeks.

     Q: So what do you make of the mixed cash/stock bid structure?
     A: It is totally unacceptable. The cash component is very small - only one
        third - and the cash is coming from the assets of our company, so there
        is no cash component on the offer. And the paper - that is two thirds -
        is overvalued paper. It has a lot of risk, and there is also a risk of
        flowback.

     Q: So what do you make of the  proposal  to on-sell  some of your assets to
        one of your biggest competitors, Iberdrola?
     A: I think it's kind of a rip-off of our shareholders. Those assets have
        been earmarked for a large competitor, and they are not getting the
        proper value that they should have. Actually, in a public auction, they
        would have a much higher value than the one they have announced.

     Regulatory issues

     Q: Why do you believe Brussels should oversee this bid?
     A: Well, we have received clear advice on how to calculate the revenues of
        the company, according to the regulations of mergers and concentrations
        with the regulations of the European Union. It is clear that more than
        one third of the turnover - more than one third of the revenues - is
        outside of Spain, because we have large operations in Italy and France.
        So we do not have two thirds in one country. Therefore, the competitive
        authorities in this case should be Brussels.



     Q: So do you feel you'll be disadvantaged by regulators if the bid doesn't
        go through?
     A: We do not think so. The regulator has to be fair. They have to regulate
        for everybody and they cannot discriminate. Maybe just the opposite; the
        White Paper studies the regulations and it goes very much along the
        lines that Endesa has been supporting.

     Returns to shareholders

     Q: Why are you announcing the sale of non-strategic assets? Is this just to
        bolster your defence?
     A: Not at all. It is not that we announced the sale of non-strategic
        assets. We have already sold other non-strategic assets; for instance,
        the telecom assets, for close to EUR 3bn. Therefore, we have a policy of
        selling those non-strategic assets and in the last 12 months we have
        sold more than EUR 3.5bn worth of assets. Right now, what we are doing
        is keeping going with this policy of selling the non-strategic assets.
        We have identified another EUR 750m worth of assets that are going to be
        sold in the short-term.

     Q: So what are you  promising in terms of  dividends?
     A: We are promising  something that the  shareholders are going to like. We
        are  promising 12 per cent.  growth in the dividend,  based on ordinary
        income, plus 100 per cent. in dividends rising from the capital gains of
        the company.

     Q: So why are you announcing specific performance targets for the first
        time now?
     A: Well, there is a bad bid on the table right now and we want our
        shareholders to evaluate properly the value of Endesa. We want to share
        with them the vision that we have for the company and the targets that
        we think we can achieve. We have identified growth in EBITDA of close to
        11 per cent. That is a EUR 3bn growth in EBITDA. The shareholders should
        now have this information, given the transparency that is needed right
        now.

     Q: And you're saying this management's committed to that?
     A: Absolutely. We are committing our own compensation to those targets and
        to achieving the goals that we are now promising to our shareholders.
