[ENDESA LOGO]                                                 Investor Relations



             RAFAEL MIRANDA UNDERSCORES THE COMPANY'S COMMITMENT TO
                PRESERVING SHAREHOLDERS' DECISION-MAKING ABILITY

o    In a speech  given in  Barcelona  as guest  speaker  at the ESADE  business
     school,  the CEO of ENDESA stated that although the E.On bid is objectively
     better for shareholders than Gas Natural's,  neither reflects the Company's
     true value.

o    Rafael  Miranda  assured that ENDESA's  standalone  business  project would
     create more value for shareholders

o    In his speech, he highlighted ENDESA's excellent 2005 results,  with record
     profits,  and the bright outlook for 2006, as well as the Company's ability
     to beat  the  targets  presented  to the  market  in  October  2005 and pay
     shareholders over Euro 7 billion in dividends in the next five years.

o    This  generous  shareholder   remuneration  policy  is  predicated  on  the
     Company's  continuing a business project that guarantees a more competitive
     and profitable company and stronger leadership than the project put forward
     by Gas Natural  with its takeover  bid,  which would  significantly  weaken
     ENDESA's position.

o    The CEO stated that over meaningful  periods of time,  ENDESA has generated
     much higher shareholder returns than Gas Natural.

New York,  April 3rd,  2006.- Last  Thursday  (March 30th,  2006) in  Barcelona,
ENDESA CEO Rafael Miranda  underscored that the Company's number one priority is
to protect and facilitate its shareholders' decision-making.

Mr. Miranda  insisted that ENDESA's  standalone  business  project is the option
that will create most value for shareholders  over both the short and long term.
He said that not only does the Gas Natural bid not add anything of  significance
to ENDESA's current  position,  but that it actually destroys value and that the
E.On bid, while certainly better from an economic  standpoint,  does not reflect
the Company's true value.

ENDESA's  CEO made these  statements  while  speaking at a session  organized in
Barcelona by the ESADE business school's alumni association.

Mr. Miranda  highlighted  ENDESA's excellent 2005 results and strong performance
in 2006,  providing  the Company  with the  confidence  that it is not only in a
position to meet, but even beat, the strategic  targets  presented to the market
in October 2005.

These targets,  which include annual net profit growth in excess of 12%,  EBITDA
growth of 10-11% and the  distribution  of over Euro 7 billion in  dividends  in
five years are clearly  designed to maximise  shareholder  returns and guarantee
consistent  value  creation  on the  basis  of the  Company's  current  business
project.

EBITDA grew Euro 1.468 billion in 2005,  as much as Gas  Natural's  total EBITDA
last year.

The European context

In his speech titled  "Endesa:  major  proyecto,  mas valor"  (Endesa:  stronger
business,  greater value),  Rafael Miranda  reviewed the bids by Gas Natural and
E.On  against the  backdrop of the current  European  Community  energy  market,
contributing his experience and vision as President of Eurelectric, the European
association of electric utilities.

He recalled that the  fulfilment  of EU economic  growth,  energy  intensity and
environmental   efficiency   targets  for  2030  required  hefty  investment  in
electricity facilities, particularly in generation and interconnection,



estimated at Euro 1 trillion between 2000-2030.  All this in the face of soaring
raw material prices and the cost of CO2 emission  rights  -currently Euro 27 per
tonne- and against the backdrop of promoting and creating  regional markets that
will subsequently merge into a single European market.

He warned that suitable,  predictable and transparent  regulation is required to
achieve  these  goals.  In  the  words  of  the  International   Energy  Agency,
"regulators  need to create stable,  transparent and  predictable  conditions to
permit deregulated market agents to assess risk".

In this  context,  the energy  issues  facing  Spain are very similar in nature:
sharp increases in fuel prices and the high cost of CO2 emission rights that are
not  reflected  in  Spain's  electricity  tariffs,  among the  lowest in Europe;
limited  capacity  to import due to the lack of  interconnections,  representing
just 4% of  installed  capacity  compared to the 10% target set by the  European
Council;  and the local  phenomenon of frequent  periods of low rainfall,  which
lead to higher generation costs and lower reserve margins.

As for Spain's  regulatory  framework,  currently  provisional,  he assured that
ENDESA is always willing to collaborate  with regulatory  authorities and bodies
to help draw up suitable proposals, as it has done in the past and will continue
to do in the future.

The Gas Natural bid: an initiative that weakens ENDESA's position in the
industry

Mr Miranda  assessed  the bids for ENDESA  with  respect to their  impact on the
Company's positioning, emphasizing the bidders' proposed business projects.

He rejected the economic  terms of Gas Natural's  bid, both the actual bid price
- -currently  scarcely  above Euro 21- and the payment  method,  which consists of
paying  two-thirds with Gas Natural shares. He emphasised that the consideration
was substantially  less than the value attached to ENDESA by applying  generally
accepted valuation  criteria.  Since this is a takeover bid that, if successful,
would mean a change of control in ENDESA,  shareholders should receive a control
premium  on the value of their  shares,  as is common  practice  in this type of
transaction.  However,  Gas Natural's  bid does not include any control  premium
whatsoever.

Mr.  Miranda also pointed out that Gas Natural's  offer was well below  ENDESA's
market price,  currently  around Euro 26.5 per share,  and that E.On's,  of Euro
27.5 per share, entailed full payment in cash.

Apart from the specific  economic  offer put forward by Gas  Natural,  which was
widely rejected and the market itself more than priced in, ENDESA's CEO said the
defence of  shareholders'  interests  required  the  Company to keep the related
business project very much in mind, since what  shareholders  were being offered
is a payment based mainly on the delivery of Gas Natural  shares,  whose current
price overstates the Company's weak medium- and long-term business prospects.

He provided  assurance in this respect  that the gas  company's  project for the
merged company would represent a significant loss of  competitiveness  and value
creation.  Gas  Natural  has argued  that its aim was to create a global  energy
leader.  However, this leader already exists...and it is ENDESA. Our EV is worth
quadruple Gas Natural's,  and with four times higher  EBITDA.  Gas Natural would
barely  contribute  any  additional  size  since  EV would  only  grow by 9% and
forecast  EBITDA  for  2005 by only  2%;  and  this at a cost of  losing  21% of
installed  capacity and 25% of our gas customers  following the asset  disposals
Gas Natural would have to carry out.

Furthermore,  the merged  company would be much less  competitive in electricity
and not be in a more advantageous position in gas.

In relation to the first question,  Mr. Miranda emphasised that as a consequence
of the disposals,  the resulting  company would: 1) lose its position as Spain's
leading  electric  utility  to its main  competitor;  2)  generate  considerable
regulatory risk; 3) lose the balance ENDESA currently enjoys between  generation
and supply and which constitutes one of its main competitive advantages; 4) have
a much worse  production  mix than ENDESA  currently has, since it would be more
dependent on gas, a fuel whose  supply is more  insecure and whose price is more
volatile than coal; and 5) also be under worse  conditions to favourably  manage
the price performance of CO2 emission rights.

He added that according to Gas Natural's  project the disposals would be carried
out as a consequence of a prior agreement  reached with  Iberdrola,  which could
constitute  collusion  and which does not  maximise the value of the assets that
would  be sold as it does not  entail a  competitive  auction  process,  thereby
seriously harming the interests of ENDESA shareholders.

As for the  position  in the gas  sector,  he  reminded  that  Gas  Natural  was
basically a distributor, whose business was facing some unfavourable prospects



given that  Spanish gas tariffs  -the highest in Europe- can only go down and is
vulnerable  to high  regulatory  risk. It is also Europe's only gas company that
does not have its own  reserves.  It would  not  diversify  ENDESA's  contracts,
enhance its bargaining  strength in gas  procurement  or its future  contracting
ability.

In short,  Gas Natural would not add value to ENDESA's gas  business,  but would
give rise to a company  with a business  that is in decline  and subject to high
regulatory risk.

Loss of international presence

Rafael Miranda  especially  emphasised the effects the Gas Natural  takeover bid
would have on ENDESA's presence in Europe.

He  pointed  out  that  ENDESA  was  currently  a  benchmark  in the EU,  with a
consolidated  business  and a  bright  future,  as  underscored  by its  ongoing
projects in the gas industry in Italy,  in  renewable  energies in France and in
generation in Poland.  Were Gas Natural's takeover to go through,  the resulting
company would lose 58% of its installed  power in Europe,  completely  disappear
from France and give up a business that  contributed Euro 425 million of profits
to ENDESA  shareholders  in 2005.  As for Latin  America,  Gas  Natural's  token
presence  there,  the scant  geographical  overlap between the two companies and
virtually  no chance of  extracting  synergies  would  render the gas  company's
contribution irrelevant.

In his speech,  the CEO  recognised  that the economic  terms of E.On's bid were
objectively  more  favourable  than  those  of Gas  Natural,  since  they  offer
shareholders  Euro 27.5 per share in cash,  enabling  shareholders to accurately
assess the price offered and, consequently, helping them make a decision.

He also  reminded  that E.On,  unlike Gas  Natural,  would  completely  maintain
ENDESA's  business project without any asset disposals.  He also pledged to keep
the company listed on Madrid and New York stock exchanges, which also safeguards
shareholders.

That said, he reiterated,  in line with the preliminary  evaluation made in this
regard  by  ENDESA's  Board of  Directors,  that the offer  does not  adequately
reflect the  Company's  real  value.  In any case,  he repeated  that one of the
Company's top priorities was to safeguard shareholders' decision-making ability.

ENDESA: stronger business, greater value

ENDESA is currently a global leader. It is the leading Spanish electric utility,
ranks second in Italy, third in France and first in Latin America, with a market
cap of  approximately  Euro 29 billion.  Mr. Miranda reminded that net profit in
2005  reached a new  all-time  high for the Company of Euro 3.18  billion.  Even
stripping  out the capital gains  generated by the disposal on non-core  assets,
recurring profit would have been Euro 1.841 billion, a like-for-like increase of
60% from 2004, and would still imply a new record for the Company.

All the company's electricity  businesses recorded growth in net profit: of Euro
1.36  billion  or 54% in Spain and  Portugal,  of Euro 425  million or 151.5% in
Europe and of Euro 262 million or 106.3% in Latin America.

Meanwhile,  these three businesses made a balanced contribution to the Company's
main financial  indicators.  EBITDA for the entire electricity  business in 2005
was Euro 6.03 billion  euros,  broken down as follows:  54% from the business in
Spain and Portugal, 15% from Europe and 31% from Latin America.

What's more,  in relation to the interests of ENDESA  shareholders,  the Company
boasts a far stronger  track record in  profitability  than Gas Natural.  In the
last six years, ENDESA shares have gained an average of 7.5% p.a., vs. 5% by the
broader Ibex 35 index. The total return  including  dividends in this period was
77.4%.

ENDESA  is also  still  the  Spanish  electric  utility  that  pays the  highest
dividend. Dividend per share for the Company rose from Euro 0.12 in 1988 to Euro
0.74 in 2004, implying a CAGR of 12%. The payout in 2005 was 57%.

In short, given the excellent results in 2005 and the upbeat prospects for 2006,
the Company estimates that EBITDA will surpass Euro 7.5 billion and net ordinary
profit Euro 2.2bn in 2009.  These figures mean  exceeding the strategic  targets
presented to the markets.

These results underscore  ENDESA's ability to provide  shareholders with a total
return via  dividends  of more than Euro 7 billion  over five years and that its
standalone  business  project will provide them more medium- and long-term value
than what the takeover bids made for the Company recognise.



Mr. Miranda highlighted in this regard that the Company's Board of Directors has
still not spoken about the value which,  in its opinion,  the Company  currently
has,  but that if the same  multiples  applied to  Iberdrola  or Union FENOSA in
transactions  either put forward or carried out over the last few years or other
yardsticks  for these types of  estimates  were  applied to ENDESA,  it would be
worth more -in some cases considerably- than Euro 30 per share.
